C I T Y OF SAN L U IS O B I S P O FROM: John Moss, Utilities Directr`— Prepared By: Gary W. He rsco: Water Division Manager 4,� SUBJECT: SALINAS RESERVOIR EXPANSION PROJECT–PROJECT APPROVAL CAO RECOMMENDATION Adopt a Resolution approving the Salinas Reservoir Expansion Project, adopting the CEQA Findings (including Statement of Overriding Considerations), approving the Mitigation Monitoring and Reporting Plan, and directing staff to file a Notice of Determination. DISCUSSION Background The City of San Luis Obispo has been pursuing the Salinas Reservoir Expansion Project as a supplemental water supply project for many years. The project involves the installation of an operable spillway gate in the existing dam which would raise the maximum water surface level by 19 feet. The maximum reservoir capacity would be increased from approximately 23,843 acre feet (af) to 41,792 af. This additional storage would increase the safe annual yield available to the City from the lake by 1,650 acre feet per year. The City of San Luis Obispo and the U.S. Army Corps of Engineers jointly hold a water rights permit (#5882) from the State Water Resources Control Board relative to the Salinas Reservoir. The permit was issued in 1941 and allows for storage of up to 45,000 acre feet. Since the gates were not installed at the time of construction the maximum storage rights allowed by the permit have not been realized. In 1991, the City requested a time extension from the State Water Resources Control Board (Board) relative to our permit. A protest was received from the California Sports Fishing Alliance relative to the City's request and a hearing was held in October of 1999 to resolve the issue. The City of Paso Robles was also a party to the hearings. The Board has issued the final Order (WR 2000 – 13) on October 19, 2000 following extensive hearings and review of submitted information. Numerous conditions were included in the Order to address concerns and issues raised during the process. One of the conditions of the Order requires the City to approve the project and file a Notice of Determination for the Salinas Reservoir Expansion Project within 25 days of the Board's adoption of the Order. This imposes a mandatory, non-negotiable deadline of November 13, 2000 for the City to submit documentation of the filing to the Chief of the Division of Water Rights. 1-1 Council Agenda Report: Salinas Reservoir Expansion Project—Project Approval Page 2 Environmental Impact Report Certification The development of the environmental impact report (EIR) for the project was initiated in 1992. The firm of Woodward-Clyde Consultants was hired by the City to prepare the necessary studies and documentation. The initial draft EIR was released for public review and comment in November of 1993 and numerous comments and concerns were raised by individuals and interested agencies. Based on the comments received, the City Council directed staff to prepare a revised draft EIR to address additional issues and areas of concern. The revised draft was released for public comment in May of 1997 and the Final Environmental Impact Report (FEIR) for the Salinas Reservoir Expansion Project was certified by the City Council on June 2, 1998. The project description as certified in the FEIR is shown below: "The purpose and objectives of the proposed project are as follows: 1) to reduce the City of San Luis Obispo's projected water supply deficit by approximately 1,650 acre feet per year (AFY) on a safe annual yield basis; 2) to increase the total storage capacity of Salinas Reservoir to provide the City greater flexibility in the use of its water resources, particularly in times of drought or other emergency; and 3) to allow the City to enjoy the benefits of its Water Rights Permit and to exercise its existing water rights thereunder by installing an operable gate in the spillway of the existing dam." Potential Project Impacts The FEIR identified a number of potential environmental impacts associated with the project. The impacts involve short-term construction related impacts as well as impacts associated with inundation of areas around the lake due to the 19-foot rise. There was also an evaluation of potential impacts to downstream resources relative to reductions in flows from the dam. The FEIR assesses the potential impacts associated with implementation of the project and includes measures to mitigate the predicted significant impacts to acceptable levels, as practical, in accordance with the California Environmental Quality Act (CEQA). The main impacts that cannot be mitigated in the short-term result from inundation of oak woodlands, riparian woodlands, native grasslands, and stream/riparian areas. Strategies were developed to mitigate these impacts in the long-term, but short-term impacts were still deemed significant until the mitigation measures mature or establish to the point that the lost habitat is restored or offset. The project would also result in a short-term significant impact due to a partial loss of public access to the County Park for one season during the construction phase. Mitigation Measures for Significant Impacts The mitigation measures for the potentially significant impacts are set forth in the FEIR. Implementation of the mitigations will reduce the majority of the impacts to a level of insignificance. In addition, the State Water Resources Control Board (SWRCB) Order Conditionally Granting an Extension of Time as adopted on October 19, 2000 includes a condition that requires preparation of a Project Operations Plan which will eliminate the FEIR 1-Z Council Agenda Report: Salinas Reservoir Expansion Project—Project Approval Page 3 finding of a significant cumulative impact on the over-drafted Paso Robles groundwater basin. The most significant environmental impacts which cannot be reduced to a level of insignificance in the short-term involve the oak and riparian woodlands inundation and the periodic inundation of the lower reaches of the several creeks and Salinas River which flow into the lake. The FEIR identifies that the increased water level, recreation facility relocation activities, and dam base modification activities would impact habitats as follows: non-native grassland (191 acres), oak woodland (84 acres), riparian woodland/forest (16.1 acres), willow woodland (35.6 acres), freshwater marsh (0.9 acre), willow woodland understory (22.1 acres), and approximately 16,050 feet of streambed habitat. These habitats will be mitigated on an in-kind basis. Oak woodland, riparian woodland, and freshwater marsh habitats will be mitigated on a 2:1 acreage ratio; grassland, willow woodland, and streambed habitats would be mitigated on a 1:1 acreage ratio. Hence,the required habitat replacement acreage or linear distance is as follows: • Grassland 191 acres • Oak woodland 168 acres • Riparian woodlands 103 acres • Freshwater marsh 1.8 acres • Willow woodland understory 22.1 acres • Streambed/aquatic habitat 16,050 feet* (* in conjunction with riparian woodland). It is anticipated that grasslands, streambed/aquatic habitat and wetlands will be successfully mitigated within 5 years. Mitigation of oak and riparian woodlands is expected to be successful within 10 years. Until the mitigation efforts are deemed successful in accordance with the performance criteria and agency reporting requirements specified in the Mitigation Monitoring and Reporting Plan, the project impacts are deemed to be significant. Mitigation Monitoring and Reporting Plan While the City has certified the FEIR for the project along with mitigation strategies, the development of a Mitigation Monitoring and Reporting Plan (Plan) is required prior to the City's approval of the project and filing the Notice of Determination. The Plan which is required by Assembly Bill 3180 has been developed and is included as Exhibit B of Attachment 1 to this report. The Plan identifies the success criteria to be used for evaluating the mitigation measures and the monitoring and reporting requirements that will be imposed to ensure that mitigation is properly carried out. If performance goals are not met, replanting or reseeding will be required. Woodlands - The success criteria developed in the Plan relative to oak and riparian woodland restoration will require that at least 80% of the targeted acreage must be successfully restored or enhanced by the 10'h year of monitoring. During the monitoring period,reporting, and replanting or reseeding will occur each year until the objectives are achieved. Monitoring will continue for 3 years after the last planting. If any plantings fail to meet success criteria described in the Plan, additional plantings or supplemental mitigation will be required. 1-3 Council Agenda Report: Salinas Reservoir Expansion Project—Project Approval Page 4 Grasslands - The Plan identifies that at least 50% of the targeted acreage of new or enhanced self-sustaining grasslands in the oak woodland understory be well-established by the 5`h year of monitoring. During the monitoring period, reporting, and replanting or reseeding will occur each year until the objectives are achieved. Monitoring will continue for 2 years after the last planting. Aquatic Habitat/Wetlands- The final major areas of mitigation involve enhancement of streambed/aquatic habitat areas to offset periodic inundation impacts on the lower reaches of streams flowing into the lake, and restoration of freshwater marsh areas to compensate for project construction impacts at the County Park and at the base of the dam. The Plan requires that mitigation results in new or restored aquatic habitat in the region of similar magnitude to that impacted. The Plan requires that at least 80% of the targeted freshwater marsh area be successfully restored or enhanced. Monitoring will continue for 2 years after the last plantings in wetland areas. If plantings fail to meet success criteria described in the Plan, additional plantings or supplemental mitigation will be required. Statement of Overriding Considerations Since there are residual significant impacts even after implementation of the mitigation measures, the City Council must make a statement of Overriding Considerations as part of its approval of the Salinas Reservoir Expansion Project. This statement is included in Exhibit A to the Resolution (Attachment 1) and is recommended for adoption by the City Council. Legal Review The Final Environmental Impact Report for the Salinas Reservoir Expansion Project has been reviewed by independent legal counsel for the City of San Luis Obispo. The Final Environmental Impact Report along with the Mitigation Monitoring and Reporting Plan adequately identify the mitigation measures that have been incorporated in the project. The opinion of our legal counsel is that the EIR meets all the requirements of CEQA and counsel concurs with the recommendation to adopt the findings, approve the Mitigation Monitoring and Reporting Plan, adopt the statement of Overriding Considerations, approve the project and file the Notice of Determination. Dam Seismic Analysis An issue that has arisen since the certification of the FEIR involves the structural analysis of the dam. The firm of URS (formerly Woodward-Clyde) was hired by the City to update the analysis prepared by Woodward-Clyde in 1989/90 based on the latest criteria of the State Division of Safety of Dams (DSOD). An initial seismic study was conducted and the results were presented to the City Council on July 18, 2000. This study included changes in the design assumptions, based on conservative evaluations and somewhat limited information. For example, the engineers opined that the existing dam (i.e. 1-4 Council Agenda Report: Salinas Reservoir Expansion Project—Project Approval Page 5 without the gates) would meet the current DSOD standards with minor remedial work. The study also opined that the expanded dam, as proposed, would not meet DSOD standards and would require strengthening measures prior to increasing the water level behind the dam. Limited preliminary options for strengthening the dam were discussed but a thorough review of all strengthening alternatives and associated costs were not part of the scope of work for the studies. Staff have discussed this preliminary report with our consultants as well as other dam safety professionals. Based on these discussions and upon further scrutiny of certain assumptions upon which the report was based, staff recommends further investigation and peer review. These additional analyses are necessary to determine what design assumptions are valid and to evaluate all potential strengthening measures in much more detail, should strengthening prove to be necessary at all. It is feasible that a more detailed analysis and additional review of the design assumptions could indicate that the existing dam structure could be expanded and meet State design standards. If future studies reveal that the dam must be strengthened, supplemental environmental review will likely be necessary to address any changes to the project description. However this will not be known until additional studies and review are completed. At this time, there is insufficient information available to warrant a change in the project description. Summary The City of San Luis Obispo has been pursuing the Salinas Reservoir Expansion Project for many years and extensive studies and evaluations have been undertaken to minimize potential environmental impacts associated with project. The mitigation measures identified in the Final EIR along with the success criteria, monitoring and reporting requirements identified in the Mitigation Monitoring and Reporting Plan will insure that project related impacts are mitigated to the extent reasonably feasible. CONCURRENCES The Community Development Department and the City Attorney concur with the recommendation. FISCAL IMPACT The specific recommended action has minimal fiscal impact. There is a$25 filing fee associated with the Notice of Determination and also an $850 fee to the Department of Fish and Game. Additional project related studies, design, construction, and mitigation costs will be identified at future stages as these items are brought forward for Council approval and funding. ALTERNATIVES Do not approve the project: Failure to approve the project and file the NOD will result in the denial of the City's request for the time extension for our permit from the State Water Resources 1-5 Council Agenda Report: Salinas Reservoir Expansion Project—Project Approval Page 6 Control Board. The denial of the request for the time extension for the City's permit will result in the City being unable to consider expanding the reservoir capacity under the existing water rights permit. This alternative is not recommended. Delay the approval of the project until additional seismic analysis is completed: Delaying approval of the project and failure to file the Notice of Determination by November 13, 2000 will result in the denial of the City's request for the time extension for our permit from the State Water Resources Control Board. The denial of the request for the time extension for the City's permit will result in the City being unable to consider expanding the reservoir capacity under the existing water rights permit. This alternative is not recommended. ATTACHMENTS 1.

DIR by Marge Erickson r GYOTILDIR ❑PERS DIR The City of San Luis Obispo thinks it needs more water to A"ejVen;cn accommodate future planned growth . In order to get more water , the City proposes to raise the height of the Salinas Dam by 19 feet . While that might not seem much , the scope of the project is immense . The capacity of the dam would be increased 75% from- 23 , 843 acre feet to 41 , 792 acre feet . The project would result in periodic inundation of an additional 395 acres of wetlands , riparian habitat and oak woodlands , including 16 ,050 linear feet of stream habitat , 73 acres of pine-oak woodland containing 1639 coast live oaks , 633 blue oaks , and 198 valley oaks , for a total of 2470 oak trees , plus 469 gray pines . Also included in the periodic innundation zone are 35 .6 acres of willow scrub/woodland , 3 .9 acres of mixed riparian woodland , 12 .2 acres of riparian forest , and degradation of 22 . 1 acres of riparian woodland understory owing to periodic innundation . The area to be inundated by the raised dam and disturbed by the relocation of recreational resources contains many species of special concern , such as the Southwestern Pond Turtle and the Two- Striped Garter Snake , as well as several federally and state endangered and threatened species , including the Bald Eagle , California Condor , White-tailed Kite , American Peregrine Falcon , Least Bell 's Vireo , Southwestern Willow Flycatcher , California Red- legged Frog . Although the City claims that there are no threatened Steelhead Trout below the dam, recent evidence suggests otherwise , and until the dam was built , they were abundant in the Salinas River . In connection with the project , virtually all of the current recreational facilities surrounding the lake will be moved , with new roads to be built and considerable cut-and-fill operations to be undertaken . In order to accommodate the increased capacity of Santa Margarita Lake, the dam will need to be substantially strengthened and the spillway will need to be armored . Before the City can undertake the project as planned , it must obtain an extension of time to complete the beneficial use granted in its water rights permit in 1941 . The State Water Resources Control Board will shortly issue its decision regarding granting the City another 10 years to complete the project . . In June 1998 , the City certified a Final Environmental Impact Report . But the FEIR does not adequately address concern adverse impacts to habitat above and below the dam, incr ase EIVED NOV 0 9 2000 11/9/00 untitled 3 Page 1 ���� SLO CITY CLERK Gj�"�� seismic vulnerability because the of greatly increased volume of water to be impounded behind the dam, adverse impacts to downstream water users , and the growth-inducing effects of the added water supply . To some extent , the State Water Resources Control Board has . recognized these deficiencies and is expected to order additional studies before it will grant the City an extension of time to increase the height of the dam. The City 's Plans To Mitigate for Lost Habitat Are Inadequate and Illusory The City recognizes that the law requires it to mitigate the detrimental impacts to the environment that the dam project will cause . However , it has not yet developed any tangible mitigation plans for the loss of riparian habitat and wetlands , and admits that any habitat restoration or creation will not reach fruition until 5 to 15 years after they are begun . The endangered and threatened species will have nowhere to be in the interim, and may be lost forever . Although the City claims it will develop a mitigation plan that will rely on restoring and/or enhancing native habitats on nearby private lands with willing landowners , thus far no land has been contracted . Currently , the only property the City is attempting to acquire is 49 acres of steep , not-in-kind habitat out of the Salinas watershed and 15 miles from the project , property that cannot provide the habitat that will be destroyed by the project . Even worse . there is some evidence that the City in fact will attempt to avoid its obligation to replace destroyed habitat by offering monetary compensation to public or private agencies , as if money can mitigate destruction of habitat and species . Seismic Concerns Recently the City received a Dam Safety Evaluation Study undertaken in order to meet the requirements of the California Department of Water Resources , Division of Safety of Dams requirements . This report concludes that the FEIR did not accurately consider the magnitude of earthquake possible along the Rinconada fault . The study concluded that the dam will be seismically unsafe unless it is strengthened beyond the degree of strengthening contemplated in the FEIR, increasing the cost of the project by $11 , 000 , 000 or over 50%. The City Did Not Plan To Mitigate for the Decreased Amount of Water it Would Be Releasing Downstream Although the City claims the increased size of the dam will have no impact or only minimal impact on the river downstream, both the State Water Resources Control Board and the National Marine 11/9/00 untitled 3 Page 2 t Fisheries Service has determined otherwise . In its draft order . the SWRCB concluded that the raised dam will contribute to the overdraft in the Paso Robles groundwater basin . The SWRCB also noted that it could not conclude that there were no Steelhead in the river below the dam or that the project would not adversely impact any steelhead that might be present . In addition , the National Marine Fisheries Service is also concerned with the downstream impacts of even the current operation of the Dam and is requesting the SWRCB to order interim releases of water . This Project Will Induce Growth and Development . The stated purpose of the project is to provide the City with an additional 1650 acre feet of water per year (AFY) . The City projects that it will require 3861 AFY of water by the year 2022 to meet growth projections . This project is projected to supply 43% of that anticipated need . That 1650 AFY could easily be supplied by water conservation and by buying up state water rights that are currently available . In fact , however , the project will supply an additional 2000 AFY for increased reserves , which can potentially provide for more growth than the City claims . , The FEIR projects that raising the dam will provide water to accommodate a portion of the City 's planned growth between now and 2022 . The FEIR projects water need at 145 gallons of water per person per day , which would allow for 5000 additional people . However , the current water usage is 123 gallons per person per day. If current water use rema.ins the same , the water contemplated by this project can accommodate an additional 12 ,000 people . If the 2000 AFY is used , then over 25 ,000 additional people could be accommodated . m Marge Erickson is an attorney (for 20 years) in Santa Barbara with a keen interest in environmental issue .

Exhibit A-;;t— 1.1 CERTIFICATION OF THE EIR The Final Environmental Impact Report (EIR) was presented to each member of the City Council who reviewed and considered the EIR and its appendices prior to certifying the EIR and prior to project approval. In addition, the City Council reviewed the administrative record and considered public comment and testimony concerning the proposed project. The City Council conducted a public hearing on the Final EIR on June 2, 1998. City of San Luis Obispo Resolution No. 9812 documents the City Council's Certification of the EIR, including the City Council members' votes. 1.2 FULL DISCLOSURE The City Council finds and certifies that the Final EIR (May, 1998) constitutes a complete, accurate, adequate, and good faith effort at full disclosure under CEQA. A summary of the public review process for the Salinas Reservoir Expansion Project EIR follows: As required by Section 15126 of the California Environmental Quality Act (CEQA) Guidelines (Title 14, California Code of Regulations), the EIR focuses on potentially significant issues, including issues of apparent public and regulatory agency concern. The Notice of Preparation (NOP)/Initial Study regarding CEQA compliance and EIR preparation for the Salinas Reservoir Expansion Project was issued by the City of San Luis Obispo (as CEQA Lead Agency) on June 29, 1992. Comments received on the NOP/Initial Study and at public "scoping" meetings held on July 22, 1992 in Santa Margarita and in the City of San Luis Obispo were considered, as appropriate, in the EIR. In addition, an initial Draft EIR for the project was issued in November 1993 and a Revised Draft EIR was issued in May 1997. Oral comments were received on the initial Draft EIR at two public hearings which were held at the City of San Luis Obispo Council Chambers and at the Centennial Park facility in Paso Robles on December 14 and 15, 1993, respectively. Additionally, oral comments were received on the Revised Draft EIR at two public hearings which were held at the Atascadero Lake Pavilion and the City of San Luis Obispo Council Chambers on July 9 and 10, 1997, respectively. Comments received at the public hearings held for the initial and Revised Draft EIRs as well as written comments are considered and addressed in the Final EIR. The City Council certified the Final EIR at a public hearing at City Council Chambers on June 2, 1998. 1.3 LOCATION OF DOCUMENTS The documents and other materials that constitute the record of proceedings upon which this decision is based are in the custody of the Utilities Department, City of San Luis Obispo. CAWINDOWSIDESKTORCEOA FINDING.DOC -2- 1-10 I \ Exhibit A-3 1.4 ADDITIONAL STUDIES TO BE COMPLETED PRIOR TO PROJECT IMPLEMENTATION The City Council has resolved that several additional studies will be performed and completed prior to project implementation. The additional studies are required to fulfill mitigation requirements specified in the Final EIR or to comply with conditions imposed by the SWRCB Order Conditionally Granting an Extension of Time as adopted on October 19, 2000. Based on the results of the forthcoming additional studies, the City may revise the mitigation plans and/or amend or supplement the Final EIR, as appropriate. Future Studies and Plans to Complete Project • National Environmental Policy Act (NEPA) compliance related studies associated with property transfer from federal to local control. • Further seismic analysis and peer review of URS study to resolve dam strength issues. • Final engineering design studies and Division of Safety of Dams review and approvals related to dam modifications to allow expansion of reservoir storage capacity from about 23,843 acre feet to 41,792 acre feet. • Final Recreation and Facility Relocation Plan, including Construction Recreation Plan component. • To implement the Habitat Mitigation Plan described in Appendix D of the Final EIR, Mitigation Site Specific Restoration/Enhancements Plans for sites to be selected for mitigation of biological impacts due to reservoir inundation. • Pre-construction Spring survey for red-legged frog along Alamo Creek and, if found, develop a long-term management program to protect the population. Studies and Plans to Comply with SWRCB Conditions (10/19/00) • Project Operations Plan specifying how the Salinas Reservoir Expansion Project will avoid contributions to the overdraft conditions in the Paso Robles Groundwater Basin. • A plan for conducting: 1) a population study to determine the occurrence of steelhead between the Salinas Dam and Highway 58; 2) a water temperature study to determine if there are temperatures adequate for summer rearing of steelhead between the Salinas Dam and Highway 58; and 3) if feasible, a stream habitat survey in the stretch of the Salinas River not previously surveyed between the Salinas Dam and Highway 58. If warranted, a plan for geomorphologic studies to identify the stream flows necessary to maintain the habitat diversity of the river channel downstream of the Salinas Reservoir dam to the Highway 58 Bridge. CAWINDOWSMESKTORCEOA FINDING.DOC -3- Exhibit ` _q 1.5 FINDINGS THAT CERTAIN ENVIRONMENTAL IMPACTS ARE UNAVOIDABLE AND ARE MITIGATED TO THE MAXIMUM EXTENT REASONABLY FEASIBLE The SWRCB Order Conditionally Granting an Extension of Time as adopted on October 19, 2000 also imposes other requirements for developing compliance plans and obtaining SWRCB approvals. These items are reflected in the Summary Mitigation Plan, the separate Mitigation Monitoring and Reporting Plan, and the overall Findings herein. The City Council finds, based upon the evidence presented to it in the EIR and in the testimony and comments in the record, that significant environmental impacts of the Salinas Reservoir Expansion Project have been mitigated to the maximum extent feasible. The impact findings include consideration of the mitigation measures specified in the Summary Mitigation Plan (Attachment 1 to these Findings), and the separate Mitigation Monitoring and Reporting Plan. Notwithstanding the imposition of feasible mitigation measures, certain environmental impacts of the Salinas Reservoir Expansion Project cannot be mitigated to a level of insignificance and, therefore, are considered to be unavoidable. These impacts are: 1) Vegetation (inundation of 73 acres of pine-oak woodland); 2) Vegetation (inundation of 51.7 acres of wetland and riparian woodlands, and periodic inundation of 22.1 acres of riparian woodland understory); 3) Vegetation (clearing and disturbance of 11 acres of oak woodland and 0.5 acre of freshwater marsh during the construction phase, including relocation of facilities at the County Park); 4) wildlife (inundation of 51.7 acres of riparian and wetland habitat on the eastern end of the reservoir); 5) aquatic ecology (inundation and conversion of about 16,000 feet of streambed habitat in tributaries to Salinas Reservoir); 6) aquatic ecology (potential impacts on red-legged frogs along Alamo Creek, if present),- 7) resent);7) recreation resources (short term loss of public access to County Park during construction phase); and 8) cumulative impacts (contribution to cumulative impacts on biological resources in Salinas River Planning Area). As discussed in the EIR, the City has committed to implement substantial biological mitigation (e.g., Habitat Mitigation Plan in Appendix D of Final EIR) which is expected to reduce identified significant impacts to levels of insignificance over time once the mitigation measures are successful. Additionally, the City has committed to perform the additional biologic and hydrologic studies required by the SWRCB Order (dated October 19, 2000). The City also intends to comply with the endangered species act. The City has also committed to implement substantial mitigation (Recreation and Facility Relocation Plan in Appendix B of the EIR) and forthcoming Construction Recreation Plan to mitigate recreation impacts at the County Park. The adverse recreation impacts at the County Park will be short term and limited to the construction phase. In the long term, recreation facilities and Park traffic circulation are expected to be improved due to implementation of the City's Recreation and Facility Relocation Plan. To the extent that impacts remain significant and unavoidable, the impacts are acceptable when weighted against the overriding social, economic, legal, technical and other considerations, including providing a long-term source of additional water to help reduce the City's projected future water supply district. The City Council's Statement of Overriding Considerations for these unavoidable significant impacts is presented in Section 1.9 of the Findings. CAWINDOWSIDESKTORCEOA FINDING.DOC 4- 1-12 Exhibit A-! 1.5 FINDINGS THAT CERTAIN ENVIRONMENTAL IMPACTS ARE UNAVOIDABLE AND ARE MITIGATED TO THE MAXIMUM EXTENT REASONABLY FEASIBLE (CONTINUED) The unavoidable significant impacts identified in the Final EIR are discussed below, along with the appropriate findings as per CEQA Guidelines Section 15091. Vegetation (1) Impacts: Construction of the proposed project would result in potential adverse effect to botanical resources in the approximate 395 acre inundation zone including loss of 84 acres of pine-oak woodland containing approximately 2,470 oak trees (1,639 coast live oaks, 633 blue oaks, and 198 valley oaks) and 469 gray pines and 191 acres of grassland habitat. (1) Mitigation Measures: Mitigation measures have been identified from the Final EIR and included in the Mitigation Monitoring and Reporting Plan (MMRP) to address said vegetation impacts to the maximum extent feasible. These mitigation measures include implementing a Habitat Mitigation Program, which results in 146 acres of new or enhanced woodlands. Oak woodland habitats would be mitigated on a 2:1 acreage ratio. Grasslands would be mitigated on a 1:1 ratio. See mitigation measure BIO-1 in Summary Mitigation Plan. (1) Findings: It has been determined that a residual significant impact will exist after mitigation until the new woodlands and grasslands are functionally self-sustaining after which, impacts are insignificant. (2) Impacts: The proposed project would also result in potential adverse effects due to an estimated net loss associated with inundation of 51.7 acres of wetland and riparian woodlands (35.6 acres of willow scrub/woodland, 3.9 acres of mixed riparian woodland, 12.2 acres of riparian forest), and the degradation of 22.1 acres of riparian woodland understory due to periodic inundation. (2) Mitigation Measures: Mitigation measures have been identified from the Final and included in the Mitigation Monitoring and Reporting Plan (MMRP) EIR to address said vegetation impacts to the maximum extent feasible. These mitigation measures include implementing a Habitat Mitigation Program. See mitigation measure BIO-1 in Summary Mitigation Plan. (2) Findings: Impacts are determined to be Significant to Insignificant ("Significant" until the mitigation [see MMRP] results in 103 acres of self-sustaining, functional riparian woodland and 22.1 acres of riparian woodland understory via implementation of enhancement/restoration measures; expected to require about 5 years; insignificant thereafter). CAWINDOWSTESKTORCEOA FINDING.DOC -5- 1-13 Exhibit A-6 1.5 FINDINGS THAT CERTAIN ENVIRONMENTAL IMPACTS ARE UNAVOIDABLE AND ARE MITIGATED TO THE MAXIMUM EXTENT REASONABLY FEASIBLE (CONTINUED) (3) Impacts: The proposed project would result in potential adverse impacts to vegetation due to clearing and disturbance during the construction phase, including relocation of recreational facilities and roadways in the County Park (including about 11 acres of oak woodland and 0.5 acre of freshwater marsh). (3) Mitigation Measures: Mitigation measures have been identified from the Final EIR and included in the Mitigation Monitoring and Reporting Plan (MMRP) to address said vegetation impacts to the maximum extent feasible. These mitigation measures include implementing a Habitat Mitigation Program. See mitigation measure BIO-1 in Summary Mitigation Plan. (3) Findings: Impacts are determined to be Significant to Insignificant ("Significant" until the mitigation results in 22 acres of new or enhanced woodlands and 1.0 acre of freshwater marsh that are self-sustaining; expected to require about 10 years for the oak woodland and 5 years for the freshwater marsh; after which impact levels would be insignificant). Wildlife (1) Impacts: The project would result in potential adverse impacts on sensitive vertebrate species in the approximate 395 acre inundation zone, including sensitive obligate riparian bird species (e.g., breeding habitat of yellow warbler) in the 51.7 acres (net) of riparian and wetland habitat that would be lost on the eastern (upstream) end of the reservoir. (1) Mitigation Measures: Mitigation measures have been identified from the Final EIR and included in the Mitigation Monitoring and Reporting Plan (MMRP) to address said vegetation impacts to the maximum extent feasible. These mitigation measures include implementing a Habitat Mitigation Program. See mitigation measure 13I0-1 in Summary Mitigation Plan. (1) Findings: Impacts are determined to be Significant to Insignificant ("Significant" until the mitigation results in 103 acres of self-sustaining, functional riparian vegetation via implementation of enhancement/restoration measures; expected to require about 5 years, after which the impact level would be insignificant). Aquatic Ecology(Inundation) (1) Impacts: The project would result in potential adverse inundation effects due to conversion of approximately 16,000 feet of streambed habitat (Salinas River, Alamo Creek, Chaparral Creek, Salsipuedes Creek, Toro Creek, and several unnamed tributaries) from intermittent stream habitat to more regularly flooded stream or pool habitat. CAWINDOW&DESKTORCEOA FINDING.DOC -6- 1-14 \ Exhibit A-`i 1.5 FINDINGS THAT CERTAIN ENVIRONMENTAL IMPACTS ARE UNAVOIDABLE AND ARE MITIGATED TO THE MAXIMUM EXTENT REASONABLY FEASIBLE (CONTINUED) (1) Mitigation Measures: Mitigation measures have been identified from the Final EIR and included in the Mitigation Monitoring and Reporting Plan (MMRP) to address said streambed habitat impacts to the maximum extent feasible. These mitigation measures include implementing a Habitat Mitigation Program. See mitigation measure 13I0-1 in Summary Mitigation Plan. (1) Findings: Impacts are determined to be Significant to Insignificant ("Significant" unless and until the mitigation results in new or restored aquatic habitat in the region of similar magnitude; expected to require about 5 years, after which the impact level would be insignificant). Recreation Resources (1) Impacts: Construction of the proposed project, including the relocation of recreational facilities and roadways in the County Park would result in short-term significant impacts on recreational opportunities and use during the construction phase due to expected partial park closures for public safety. (1) Mitigation Measures: Implementation of the Recreation and Facility Relocation Plan (see Appendix B of Final EIR) will fully mitigate long term impacts to the County Park. The forthcoming Construction Recreation Plan will mitigate short term construction phase impacts at the County Park to the extent practical. See mitigation measure REC-1 in Summary Mitigation Plan. (1) Findings: Significant(short-term); Insignificant in long-term. Cumulative Impacts (1) Impacts: Contribution to short-term cumulative impacts on biological resources in the Salinas River Planning Area. (1) Mitigation Measures: Mitigation measures have been identified from the Final EIR and included in the Mitigation Monitoring and Reporting Plan(MMRP) to address said biological resource impacts to the maximum extent feasible. These mitigation measures include implementing a Habitat Mitigation Program. (1) Findings: Significant to Insignificant ("Significant" until the biological resources mitigation is successful). (2) Impacts: Incremental contribution to cumulative impact on existing overdraft condition in the Paso Robles groundwater basin. CAWINDOWMEWORCE0A FINDINGLOC -7- 1-15 Exhibit A-8 1.5 FINDINGS THAT CERTAIN ENVIRONMENTAL IMPACTS ARE UNAVOIDABLE AND ARE MITIGATED TO THE MAXIMUM EXTENT REASONABLY FEASIBLE (CONTINUED) (2) Mitigation Measures: (a) offer to participate in development of basin management plan; (b) prepare and submit to SWRCB a Project Operations Plan specifying how the project will avoid contributing to the overdraft condition. (2) Findings: Insignificant. 1.6 FINDINGS THAT CERTAIN IMPACTS ARE MITIGATED TO LEVELS OF LESS THAN SIGNIFICANCE BY PROJECT REDESIGN OR BY CONDITIONS OF APPROVAL The Final EIR identified several subject areas for which the project is considered to have the potential to cause or contribute to significant environmental impacts that can be reduced to insignificant levels by incorporation of feasible mitigation measures into the project approval. The City Council finds that the following potentially significant impacts have been reduced to the level of insignificance as a result of the mitigation measures incorporated into the project approval_ Each of the mitigable impacts is discussed below along with the appropriate findings as per CEQA Section 15091. Soils and Topography (1) Impacts: Construction activities associated primarily with relocation of recreation facilities in the County Park would disturb approximately 25 acres of soils and topography, including cut-and-fill of approximately 150,000 cubic yards of material; the areas to be disturbed include moderately to highly erodible soils that could be subject to accelerated erosion following construction. (1) Mitigation Measures: Implement soil erosion and sediment control measures as necessary during construction; following construction, perform reclamation and revegetation of disturbed areas; perform monitoring of reclaimed/revegetated areas and implement supplemental corrective measures in problem erosion areas, as applicable. See mitigation measures SOILS-I through SOILS-6 in Summary Mitigation Plan. (1) Findings: Insignificant. Geology (1) Impacts: Seismically-induced damage to the right abutment of the dam related to severe groundshaking of the potentially unstable right abutment bedrock. (1) Mitigation Measures: Implement the proposed remedial measures to strengthen the right abutment such as installation of post tensioned rock anchors (or other appropriate means) as determined during the planned detailed engineering analysis(in accordance with Division of Safety of Dams requirements). See GEO-DAM SAFETY in Summary Mitigation Plan. CAWINDOWS\DESKTORCEOA FINDING.DOC -8- 1-16 Exhibit A-1 1.6 FINDINGS THAT CERTAIN IMPACTS ARE MITIGATED TO LEVELS OF LESS THAN SIGNIFICANCE BY PROJECT REDESIGN OR BY CONDITIONS OF APPROVAL (CONTINUED) (1) Findings: Insignificant. (2) Impacts: Seismically-induced damage due to ground failure at the relocated recreational facility and roadway areas that are on newly created fill. (2) Mitigation Measures: In areas to be filled, use blended fill which is at least 2 parts sandstone to 1 part mudstone to mitigate concerns regarding the use of mudstone. Clayey soils should be blended with sandstone and/or treated with lime to minimize shrink-swell potential. Compaction of local fill materials should be accomplished wet of optimum. See mitigation measure GE04 in Summary Mitigation Plan. (2).Findings: Insignificant. (3) Impacts: Scour-related damage to the dam base as a result of dam overtopping during a major flood. (3) Mitigation Measures: Install concrete armoring over an approximate 0.4 acre area at the base of the dam to preclude scouring damage in accordance with the proposed project design. See mitigation measure GEO-DAM SAFETY in Summary Mitigation Plan. (3) Findings: Insignificant. (4) Impacts: Seepage related damage to the left abutment of the dam associated with increased reservoir level/pressure and movement of water through fractures in the abutment bedrock. (4) Mitigation Measures: Implement the proposed remedial grouting program prior to raising the reservoir level and/or monitor seepage and perform grouting, as necessary. See mitigation measure GEO-2 in Summary Mitigation Plan. (4) Findings: Insignificant. (5) Impacts: Damage to relocated recreational facilities and roadways in the County Park due to slope failure in cutslope areas. (5) Mitigation Measures: Employ conservative design of cutslope inclinations including constructing benches in any cutslopes greater than 25 to 30 feet in height-, limit cutslopes to no steeper than 2:1 horizontal to vertical in sandstone, 2.5:1 in mudstone, and 3:1 in clayey colluvial soils. Prepare detailed grading and slope stabilization/restoration plans during the detailed design phase for implementation during the construction phase. Perform all cut-and- fill operations under the supervision of a qualified geotechnical engineer. See mitigation measure GEO-3 in Summary Mitigation Plan. C:IWINDOWSIDESKTORCEOAFINDING.DOC -9- 1-17 / Exhibit A-10 1.6 FINDINGS THAT CERTAIN IMPACTS ARE MITIGATED TO LEVELS OF LESS THAN SIGNIFICANCE BY PROJECT REDESIGN OR BY CONDITIONS OF APPROVAL (CONTINUED) (5) Findings: Insignificant. (6) Impacts: Induced-landslide related slope failure and endangerment of public safety due to inundation and saturation of existing landslide areas. (6) Mitigation Measures: Implement slope stabilization measures (if deemed necessary during the final design phase), monitor slope stability in areas of concern following the construction phase, and implement additional stabilization/safety measures until any remaining unstable areas are stabilized, as appropriate. See mitigation measure GEO-1 in Summary Mitigation Plan. (6) Findings: Insignificant. Air Quality (1) Impacts: Exceedance of San Luis Obispo County Air Pollution Control District's (SLOAPCD) significance threshold criteria for NO,, and PM10 emissions during the construction phase of the project. No project-related air emissions are expected to occur during the operational phase. (1) Mitigation Measures: Implement Best Available Control Technology (BACT) measures for NO,, emissions in accordance with the SLOAPCD's specifications for projects that will move 50,000 cubic yards of material (or more) within any 3 month period, and the SLOAPCD's "additional measures". Implement the SLOAPCD's measures for mitigating PM10 emissions for projects that exceed 4.0 acres of grading in a quarter. See mitigation measures AQ-1 through AQ-5 in Summary Mitigation Plan. (1) Findings: Insignificant. Water Resources/Quality (1) Impact: Temporary construction related deterioration of surface water quality in Salinas Reservoir and the Salinas River due to project related erosion and sedimentation. (1) Mitigation Measures: Implement erosion control and stabilization procedures for all disturbed areas and construct siltation/sedimentation basins or control structures, as appropriate. See mitigation measure WATER-1 in Summary Mitigation Plan. (1)Findings: Insignificant. (2) Impacts: Deterioration of surface water and/or groundwater quality due to accidental spills of fuel,lubricants, or hazardous materials during the construction or operational phase. CANNDOWSIDESKTORMA FINDING.DOC -10- 1-18 Exhibit A'1 I 1.6 FINDINGS THAT CERTAIN IMPACTS ARE MITIGATED TO LEVELS OF LESS THAN SIGNIFICANCE BY PROJECT REDESIGN OR BY CONDITIONS OF APPROVAL (CONTINUED) (2) Mitigation Measures: Design, construct, and operate all facilities or operations in accordance with applicable regulations; perform refueling and maintenance of construction equipment only in designated lined and bermed areas; prior to initiation of construction, prepare spill contingency plans for implementation, if necessary. See mitigation measure WATER-2 in Summary Mitigation Plan. (2) Findings: Insignificant. (3) Impacts: Potential adverse hydrologic or hydrogeologic effects in the Salinas River area downstream from the reservoir due to decreases in downstream flows during the winter months of above normal rainfall years. The worst-case incremental project related average annual reduction in downstream flow based on computer model simulations is 2041 acre feet for the period of record from 1972-1995 and 1841 acre feet for the period of record from 1943-1995. The average annual flows at selected downstream points using the 1972-1995 period of record with and without the project are: Average Flow Average Flow Location Without Project(AFY) With Project(AFY) Base of Dam 14,927 12,886 Atascadero 27,614 25,647 Paso Robles 72,547 70,579 Bradley 360,726 358.759 Spreckels 305,361 303,393 The maximum possible annual incremental reduction in downstream flow is 17,949 AF. The average annual reduction in groundwater levels in shallow and deep wells in Atascadero based on historical groundwater data and computer modeling is estimated to be 0.14 and 0.46 feet, respectively. The maximum annual incremental reductions in shallow and deep wells in Atascadero are estimated to be 1.54 and 4.15 feet, respectively. Groundwater impacts would be less discernible downstream of Atascadero. (3) Mitigation Measures: The SWRCB's Order Conditionally Granting an Extension of Time (as adopted October 19, 2000) on the City's water rights petition requires that the City prepare a Project Operations Plan (for expanded reservoir) to avoid any contribution to the overdraft condition of the Paso Robles groundwater basin. See mitigation measure WATER-3 in Summary Mitigation Plan. (3) Findings: Project-specific flow reductions are not expected to be significant, however, the cumulative effects of the overall surface water diversions and groundwater withdrawals by all downstream users could be considered significant. With implementation of the SWRCB ordered Project Operations Plan, the cumulative contribution of the Salinas Reservoir Expansion Project would be insignificant. CAWINDOWSTESKTOPICEOA FINDING.DOC _11- 1-19 Exhibit Alz-- 1.6 FINDINGS THAT CERTAIN IMPACTS ARE MITIGATED TO LEVELS OF LESS THAN SIGNIFICANCE BY PROJECT REDESIGN OR BY CONDITIONS OF APPROVAL (CONTINUED) Vegetation (1) Impacts: Potential adverse effects due to inundation of two Hickman's checkerbloom plants (CNPS List 113, Rare or Endangered California and elsewhere) near the mouth of Chaparral Creek; this species is rare in San Luis Obispo County. (1) Mitigation Measures: Re-establish these plants in suitable habitat above the inundation zone prior to raising the dam. See mitigation measure BIO-2 in Summary Mitigation Plan. (1) Findings: Insignificant. Aquatic Ecology(Downstream) (1) Impacts: Potential adverse effects on downstream aquatic resources due to project- related flow reductions in the winter months of wet years. Continuation of the "live stream agreement" is expected to protect downstream water users and aquatic resources during periods of low flow. The assessment conducted for the EIR concluded that no adverse impacts to downstream aquatic habitats would occur due to project related reductions in spill frequency and amount. Therefore, no significant impacts on downstream aquatic ecology would be expected to occur. The proposed project would not adversely affect steelhead that either use the mainstem of the river below the dam for migration, or that use the mainstem for spawning and rearing habitat because of the following reasons. The project would only affect the magnitude and frequency of the spill events. During non-spill years, which account for most years, there would be no change in the amount or timing of downstream flows. Additionally, the average reduction in the depth and velocity of flows downstream of the dam during spill events were estimated to be less than two inches and one foot per second respectively. These reductions are not large enough to adversely affect the ability of the steelhead to migrate upstream to tributaries below the dam, particularly because the effect of reduced spills would be attenuated with distance from the dam. Finally, the reduction in spill frequency and amount is not expected to adversely affect potential spawning and rearing habitat along the mainstem below the dam because the effect on spills would typically occur early in the wet season prior to spawning and rearing activities. (1) Mitigation Measures: Although the Final EIR concluded that the proposed project would not adversely impact downstream aquatic resources, including steelhead, the SWRCB has ordered the following mitigation to make sure that the downstream habitat is not adversely impacted. Conduct additional biologic and hydrologic studies downstream of the dam between Salinas Dam and Highway 58 to assess whether suitable habitat for steelhead spawning and rearing is present and, if so, what flows are necessary to maintain habitat diversity in the channel. In addition, consult with the National Marine Fisheries Service regarding steelhead. See mitigation measure BIO-1 (refer to additional SWRCB measures) in CAWIN00WSUESKT0PXCEOA FINDING.DOC -12- 1-20 Exhibit A--15 1.6 FINDINGS THAT CERTAIN IMPACTS ARE MITIGATED TO LEVELS OF LESS THAN SIGNIFICANCE BY PROJECT REDESIGN OR BY CONDITIONS OF APPROVAL (CONTINUED) Summary Mitigation Plan. Implementation of any forthcoming SWRCB conditions based on the results of additional hydrologic and biologic studies to be performed between the dam and the Highway 58 bridge (required by the SWRCB) are expected to preclude significant impacts due to project effects. (1) Findings: Insignificant. (2) Impact: The California red-legged frog is a state and federal endangered species and may be present at the reservoir and/or its tributaries (i.e., Alamo Creek); one adult frog was found during the 1992 surveys but none were found in 1996. The general absence of this species, or its apparent small population, may be due to the predatory effects of the introduced bullfrogs and sunfish that reside in the lake. Increasing the water level in the lake would extend suitable habitat for the bullfrog and sunfish up Alamo Creek and other tributaries to the lake. Increasing the habitat for the bullfrog could adversely affect any population of red-legged frog that may still exist along the upper reaches of Alamo Creek and other tributaries to the lake. This impact is considered potentially significant. The actual magnitude of this impact or its probability cannot be predicted. It is possible that the red-legged frog is absent from the Salinas River, and that the population along Alamo Creek is very small or non-existent. (2) Mitigation Measures: Implement an intensive survey in the Spring preceding the initiation of construction to locate and assess the red-legged frog population, if present, along Alamo Creek. If present, develop and implement a long-term management program to monitor and protect the population using aquatic habitat improvement measures, predator control, and possibly installation of an in-stream barrier to limit predator (i.e., bullfrog) access. See mitigation measure BIO-4 in Summary Mitigation Plan. (2) Findings: With implementation of mitigation, the potential impacts to this species would be expected to be reduced to a level of insignificance. If red-legged frogs are indeed still present and the proposed mitigation is unsuccessful, adverse affects on any remaining individuals would be considered significant. Land Use Construction and operation of the proposed project would be expected to be consistent with A the identified County plans, goals, and policies that would be potentially applicable to the project. No significant land use impacts are expected. Recreation Resources Implementation of the proposed project will result in inundation of the existing County Park facilities and roadways. The proposed Salinas Reservoir Recreation and Facility Relocation Plan (see Appendix B of the FEIR) will replace the inundated facilities. With implementation Q%WINDOWS%DESKT0*'TEOA ANDING.DOC -13- 1-21 �01 Exhibit A-11 1.6 FINDINGS THAT CERTAIN IMPACTS ARE MITIGATED TO LEVELS OF LESS THAN SIGNIFICANCE BY PROJECT REDESIGN OR BY CONDITIONS OF APPROVAL (CONTINUED) of the proposed Recreation and Facility Relocation Plan, no long-term significant recreation impacts are expected. Visual and Aesthetics (1) Impacts: Degradation of visual quality in areas to be graded in the County Park (associated with recreational facility and roadway relocations) until denuded areas are revegetated. (1) Mitigation Measures: Implement measures recommended to mitigate impacts to soils and vegetation (i.e., stabilization, reclamation, and revegetation of disturbed areas [except rocky areas]). (1) Findings: Insignificant. (2) Impacts: Potential long-term adverse visual impacts associated with the presence of dead trees in the inundation zone. (2) Mitigation Measures: Remove dead trees in the inundation zone following project implementation if the County determines that the trees constitute an adverse visual impact; removal to be selective and limited to sensitive viewing areas (unless removal is warranted for other reasons such as to reduce navigational hazards to boats). (2) Findings: Insignificant. Traffic and Circulation (1) Impacts: Potential short-term adverse traffic related impacts during the construction phase due to commuting workers and material/equipment truck deliveries (up to 100 per day) through the town of Santa Margarita and within the County Park. (1) Mitigation Measures: Stipulate that the construction contractor must require strict adherence to applicable speed limits (to increase safety, reduce noise and vibration, and reduce dust generation), and use flagmen within the County Park to direct traffic during the construction phase. Refer to mitigation measure TRAFFIC-1 in Summary Mitigation Plan. (1) Findings: Insignificant. Noise (1) Impacts: Potential short-term adverse noise impacts due to truck traffic during the construction phase in the town of Santa Margarita and at the County Park. CANNDOWMEWORCEOA FINDING.DOC -14- 1-22 \ Exhibit A_�s 1.6 FINDINGS THAT CERTAIN IMPACTS ARE MITIGATED TO LEVELS OF LESS THAN SIGNIFICANCE BY PROJECT REDESIGN OR BY CONDITIONS OF APPROVAL (CONTINUED) (1) Mitigation Measures: Limit construction related truck traffic to weekdays between 7:00 AM and 8:00 PM, and require the construction contractor to utilize adequate mufflers on trucks and applicable construction equipment. Refer to mitigation measures NOISE-1 and NOISE-2 in Summary Mitigation Plan. (1)Findings: Insignificant. Cultural Resources (1) Impacts: Impacts to significant cultural resources due to inundation or direct disturbance during earth moving activities. (1) Mitigation Measures: Mitigate effects via site evaluation, documentation, data recovery and/or resource relocation, as applicable, in accordance with Section 106 of the NHPA and implementing regulations in 36 CFR 800. Refer to mitigation measures CUL-1 through CUL-3 in Summary Mitigation Plan. (1) Findings: Insignificant. (2) Impacts: Impacts to the historical significance of Salinas Dam (recommended eligible for the National Register of Historic Places) due to spillway modification and dam strengthening activities. (2) Mitigation Measures: Mitigate effects by assessing and documenting the dam's historical significance and condition to standards of the State Office of Historic Preservation and the National Park Service. Refer to mitigation measure CUL-4 in Summary Mitigation Plan. Note: the required Historic Architectural Engineering Record (HAER) documentation has already been completed and submitted to the National Park Service. (2)Findings: Insignificant. Risk of Upset/Human Health (1) Impacts: Flooding in downstream areas in the highly unlikely event of a dam failure, including up to approximately an additional 17,949 AF of water associated with expansion of the existing reservoir. A sudden dam failure would likely cause substantial flooding in the narrow canyon below the dam and would increase flood depths (with respect to the existing reservoir volume) as far downstream as the town of Bradley. In the highly unlikely event that the dam failed, significant downstream effects would be expected to occur for many miles downstream. CAWINDOWMDESKTORCEOA FINDING.DOC -15- 1-23 Exhibit A—(to 1.6 FINDINGS THAT CERTAIN IMPACTS ARE MITIGATED TO LEVELS OF LESS THAN SIGNIFICANCE BY PROJECT REDESIGN OR BY CONDITIONS OF APPROVAL (CONTINUED) (1) Mitigation Measures: Implement the proposed dam strengthening and protection plans in accordance with the specifications to be developed during the detailed engineering design in accordance with Division of Safety of Dam (DSOD) requirements. The proposed project includes standard procedures/methods for reducing potential dam failure/flood risks to acceptable levels. Refer to mitigation measure GEO-DAM SAFETY in Summary Mitigation Plan. (1) Findings: Insignificant. (2) Impact: A recent preliminary seismic safety report opines that the existing dam would require some fortification, to the extent presently unknown, for the project to be completed. The City recently commissioned an update of previous seismic safety studies of the Salinas Dam. Studies of this issue will be ongoing in the future as the City prepares engineering plans and applies to the Division of Safety of Dams (DSOD) for approval of the reservoir expansion project. One preliminary study has been completed by USR Greiner Woodward Clyde. This study was based upon assumptions and partially completed data. The study, contrary to earlier studies, concluded for an expanded reservoir volume that the existing dam structure was not sufficient to withstand the magnitude of seismic event predicted by the report. This conclusion was based upon certain assumptions and conclusions regarding potential seismic events in the vicinity of the dam, as well as other assumptions that may not be supportable. The issue merits further expert analysis, inquiry into the basis for the report's assumptions, and peer review. The City intends to commission additional studies, analysis, and peer review to arrive at resolution of the contradictory evidence that it has received to date regarding dam safety issues. A comment has been made that the URS Greiner report constitutes new information that requires preparation of a new EIR. The City does not agree that this comment is valid at this time. The new information is one expert's opinion. It is contrary to the opinions provided in earlier reports used in preparation of the EIR. The City is not prepared to accept this expert's opinion for the purpose of approving this project and will rely upon the EIR instead. Where there are conflicting expert opinions on a subject, the City may exercise its discretion in determining upon which it will rely in approving the project. (2) Mitigation Measures: None adopted or proposed at this time. Until further analysis can be conducted, the City has received conflicting information. There is substantial evidence in the record to support the EIR's conclusion that with the mitigation measures recommended and analyzed in the EIR, the dam will be safe with the project. The City is not prepared to accept the conclusions of the URS Greiner report without peer review, analysis of the assumptions and evidence upon which the report was based, and further field investigation. The City proposes to conduct further studies, and will continue to do so in the course of conducting final engineering design work and applying for DSOD approval. (2) Findings: Insignificant but should the additional studies conducted by the City result in a recommendation for dam modifications, the modification options will be reviewed and additional environmental review conducted as needed. CAW INDOWSADESKTORCEDA FINDING.DOC -16- 1-24 Exhibit A-11 1.7 FINDINGS THAT THERE ARE NO SIGNIFICANT IMPACTS WITH PROJECT AS PROPOSED Aquatic Ecology (Inundation) (1) Impact: The southwestern pond turtle is a California Species of Special Concern that is known to be present in the project area. Raising the lake level is not expected to result in a substantial loss of suitable habitat for this species which currently adapts to the ever- changing water level in the reservoir under current conditions. It is anticipated that new emergent wetland vegetation would become established rapidly after increasing the water level, providing shoreline habitat for this species. (1) Mitigation Measures: None. (1) Findings: Insignificant. Growth Inducement Accommodation of a portion of the City's planned growth between now and 2022 when the City's General Plan buildout population of 56,000 is expected to be reached; the proposed project would provide an estimated 1650 AFY of new water supplies on a safe annual yield basis -- this amount of water could support a portion (5000 people) of the allowable additional population until the General Plan buildout population is reached; population growth has the potential to result in cumulative effects on air quality, traffic, noise, etc. Assuming the City continues to control the rate of growth in accordance with the City's approved General Plan, no significant project-related effects are anticipated. Energy Use The proposed project would be expected to reduce the need to operate the electric pumps near the dam base and to increase electrical consumption at the pumps at the Cuesta Grade booster station facility, assuming more water is conveyed in the future associated with the proposed project. The electrical supply for project pumps is provided by Pacific Gas and Electric Company (PG&E). The additional energy requirements of the project are insignificant. Cumulative Impacts The Salinas Reservoir Expansion Project will contribute to temporary area-wide cumulative effects on traffic, air quality, noise, etc. during the construction phase when considered together with other projects occurring in the same geographic area of influence. No other specific projects were identified that would result in significant cumulative effects in the project area during the construction phase. CAWIN00WSIDESKT0RCEOA FINDINGLOC -17- 1-25 Exhibit A�18 1.7 FINDINGS THAT THERE ARE NO SIGNIFICANT IMPACTS WITH PROJECT AS PROPOSED (CONTINUED) The project has the potential to contribute to area-wide cumulative effects during the operational phase related to the growth accommodating aspects of the project within the City of San Luis Obispo's urban reserve line. As discussed for Growth Inducement, no significant impacts are anticipated. The project also has the potential for cumulative effects during the operational phase related to growth accommodation and downstream flow effects when considered together with the possible future Nacimiento Reservoir Water Supply Project. The City does not currently plan to obtain supplemental water supplies from both projects, thus cumulative impacts are not expected. 1.8 FINDINGS REGARDING ALTERNATIVES Alternatives The Final EIR assesses a range of alternatives to the proposed project,including: 1) other water supply alternatives considered (Nacimiento Water Supply Project, seawater desalination, increased storage in Whale Rock Reservoir via transfers from Salinas Reservoir, and cloud seeding);2) alternate technologies/methods for expanding the reservoir capacity and alternate reservoir expansion volumes;3)alternatives removed from further consideration;and 4) the No Project Alternative.An overview of the alternatives which have been considered is presented in the following sections—refer to Section 4.0 of the Final EIR for more information. Other Water Supply Alternatives Considered The purpose of the proposed project is to provide the City with 1650 AFY of additional water supplies on a safe annual yield basis. The only alternatives to the proposed project that have been identified which could potentially supply up to 1650 AFY on a safe annual yield basis, are the Nacimiento Water Supply Project,seawater desalination,and possibly increased storage in Whale Rock Reservoir via transfers from Salinas Reservoir.Of these three alternatives,only the Nacimiento Water Supply Project is currently being pursued by the City. Nacimiento Water Supply Project The Nacimiento Water Supply Project is proposed by the County of San Luis Obispo and would involve conveyance and beneficial use of a portion of the County's entitlement of 7,500 AFY of water from Lake Nacimiento in northern San Luis Obispo County. The County's entitlement has been tentatively allocated amongst various water purveyors in San Luis Obispo County.The City of San Luis Obispo has requested an allocation of 3380 AFY. The feasibility of this project is currently still being assessed, and an environmental impact report is currently being prepared for the project by the County of San Luis Obispo. The County of San Luis Obispo has indicated that they intend to prepare and issue a Revised Draft CAWINDOWS\DESKTORCEOA FINDING.DOC -18- 1-26 Exhibit A-11 1.8 FINDINGS REGARDING ALTERNATIVES (CONTINUED) EIR for the Nacimiento Project.The Revised Draft EIR is anticipated to address revisions to the project(e.g.,alternative water intake structures at the lake,new pipeline alignments,etc.)as well as numerous environmental issues raised in the public and agency comment letters received on the Draft EIR (August 1997). The Revised Draft EIR is expected to be completed in 2001. Due to uncertainties regarding the ultimate configuration of the Nacimiento Project and the associated environmental impacts,the feasibility of the Nacimiento Project is currently unknown. Seawater Desalination Previous analysis of the seawater desalination alternative by the City in 1991 determined that implementation of this water supply alternative could result in multiple significant effects on the environment and that the desalinated water would be very expensive.This alternative is not considered to be feasible at the present time and is not considered to be environmentally preferable to the proposed project. Whale Rock Transfers Another potential alternative for increasing the City's water supply would be to transfer water via pipeline from Salinas Reservoir to Whale Rock Reservoir. Preliminary analysis of this alternative (see Final EIR Section 4.2.4, Increased Storage in Whale Rock Reservoir via Transfers from Salinas Reservoir, indicates that it is probably not feasible and it could adversely affect other users of Whale Rock Reservoir water. In summary,the feasibility of this alternative is questionable related to the following issues: unknown ability of existing pipeline and conveyance facilities to handle reversed flow and associated pressures; potential for introduction of non-native species and/or lower quality water into Whale Rock Reservoir from Salinas Reservoir; and the potential yield of this alternative in terms of safe annual yield is unknown and subject to multiple variables outside of the City's control and this alternative could interfere with normal deliveries of water from Whale Rock Reservoir to other users which rely on pipeline flows in the opposite direction. New Reservoir The possibility of constructing a new reservoir has not been seriously considered because it would be expected to result in substantially more environmental effects than the proposed project and no potentially feasible sites(e.g., suitable canyon location covering a large enough area and that has existing water rights which the City could assume)have been identified. Alternate Techniques Considered for Modifying Dam Alternative techniques for modifying the dam to increase the storage capacity of Salinas Reservoir have been considered and include other ways of structurally modifying the spillway and/or dam crest. None of these alternatives are currently considered to be preferable to the proposed project design which involves installation of an operable gate in the existing dam spillway. CAW INDOWSIDESUORCEOA FINDING.DOC -19- 1-27 Exhibit A-zo 1.8 FINDINGS REGARDING ALTERNATIVES (CONTINUED) Alternatives Removed From Further Consideration State Water Project Although the City of San Luis Obispo had an opportunity to participate in the State Water Project prior to construction of the Coastal Branch Phase II extension that connected San Luis Obispo and Santa Barbara County communities to the terminus of State Water Project facilities in Kern County, City of San Luis Obispo voters in an election held in 1992 voted against that participation. Several communities within San Luis Obispo County opted to participate in the Coastal Branch project and, as a result obtained entitlements (4830 AFY) to State Water Project water and to capacity in the Coastal Branch. The Coastal Branch pipeline has been constructed and its capacity fully committed.In order to gain entitlement to a permanent supply of State Water Project water and to receive continuous deliveries through the portion of the Coastal Branch pipeline that passes the City, the City would have to purchase entitlement(and thus capacity rights) from a participant adjacent to, or downstream of, the City. The Salinas Reservoir Expansion Project is expected to increase the safe annual yield of the reservoir by 1650 AFY. No other subscriber to the State Water Project with entitlement to capacity in the portion or "reach" of the Coastal Branch pipeline that could serve the City has offered to permanently sell or transfer any part of that entitlement.The purpose of the project is not solely to augment annual water supplies.The Salinas Reservoir Expansion Project would also provide increased storage from which the City could draw during drought periods and would allow the City to enjoy certain water storage rights of which it has been unable to take advantage due to the incomplete construction of the dam as designed.The State Water Project does not represent a feasible alternative to the project. Consequently,participation in the State Water Project was not carried forward in this EIR as a potentially feasible project alternative. No Project Alternative The "No Project" alternative would result in no environmental impacts. However, this alternative would not be consistent with the purpose and need for the project and would limit the ability of the City to fulfill its obligations to meet projected future water supply needs within the City. The "No Project" alternative would leave the City with no present feasible option to provide the storage, yield, and other benefits of the project necessary to serve the water needs of its water users set forth in more detail in the Statement of Overriding Considerations. Therefore, the City Council finds that specific economic, social, or other considerations make infeasible the "No Project" alternative identified in the EIR and that the proposed project as adopted is preferable. Environmentally Superior Alternative The No Project Alternative would result in the least environmental effects. However, the No Project Alternative would not meet the project goals (i.e., City's need to reduce its projected water supply deficit of approximately 3861 AFY by the year 2022), and it is not considered to be a reasonable or feasible alternative. CAW INDOWSOESKrORCEOA FINDING.DOC -20- 1-28 Exhibit A2) 1.8 FINDINGS REGARDING ALTERNATIVES (CONTINUED) This Final EIR for the Salinas Reservoir Expansion Project considers the results of the Draft EIR (August 1997) for the Nacimiento Water Supply Project, and evaluates and compares the environmental effects of the two projects (refer to Final EIR Section 4.2.2). As of November, 2002,the County of San Luis Obispo has indicated that they intend to prepare a Revised Draft EIR for the Nacimiento Project; the Final EIR is not expected to be certified until sometime in 2002. The feasibility of the Nacimiento Project relative to environmental impacts,water rights, economics, and timeframe for implementation are currently unknown. Additionally,approval and implementation of the Nacimiento Project are not within the City of San Luis Obispo's jurisdiction. The Salinas Reservoir Expansion Project is considered by the City of San Luis Obispo to be the only feasible alternative at the time the Final EIR was prepared and at the time of project approvals in November 2000. Therefore, the Salinas Reservoir Expansion Project is currently considered to be the environmentally superior alternative. 1.9 STATEMENT OF OVERRIDING CONSIDERATIONS The EIR for this project identifies the impacts discussed above in Section 1.4 as being unavoidable, adverse significant impacts. Pursuant to CEQA Guidelines Section 15093, the City Council makes the following Statement of Overriding Considerations that warrants approval of this project notwithstanding the identified impacts that are not mitigated to a less than significant level. Having balanced the benefits of the proposed project against the significant and unavoidable effects, the City Council hereby determines that the benefits outweigh the significant and unavoidable effects and that these effects are nonetheless acceptable, based on the following individual and collective overriding considerations. The project will: • Reduce the City of San Luis Obispo's projected water supply deficit by approximately 1650 acre feet per year(AFY)on a safe annual yield basis; • Increase the total storage capacity of Salinas Reservoir to provide the City with greater flexibility in the use of its water resources, particularly in times of drought or other emergency; and • Allow the City to enjoy the benefits of its Water Rights Permit and to exercise its existing water rights thereunder by installing an operable gate in the spillway of the existing dam. CAWINDOWS0ESKT0PICEOA FINDING.DOC -21- 1-29 Exhibit A-22 1.10 ENVIRONMENTAL REPORTING AND MONITORING PROGRAM Public Resources Code Section 21081.6 requires the lead agency to adopt a reporting or monitoring program for the changes made to the project or conditions of project approval, adopted in order to mitigate or avoid significant effects on the environment. The approved project description with its corresponding mitigation monitoring and reporting plan (MMRP) requirements, are hereby adopted as the monitoring program for this project. The monitoring program is designed to ensure compliance during project implementation. The MMRP is a separate document (Exhibit B to Resolution) which has been considered in these Findings and has been approved and adopted by the City Council.

Monitoring will occur for 10 years following initiation of restoration and/or enhancement. The activities are described below and in Table A-1 and supplement the Habitat Mitigation Plan Approach (HMP) as provided in Appendix D of the Final Environmental Impact Report (FEIR) for the Salinas Reservoir Expansion Project(May 1998). This Plan also considers biological mitigation related measures specified in the State Water Resource Control Board's (SWRCB) Order Conditionally Granting an Extension of Time as adopted October 19, 2000. The Summary Mitigation Plan (Attachment 1 to CEQA Findings) itemizes the Board's biology related Orders that require additional studies and plan reviews. This Plan will be modified, if necessary, once the studies and plan reviews ordered by the Board are completed. 1.0 MONITORING REQUIREMENTS The mitigation program presented in the HMP represents a practical and feasible approach to provide compensation for wetlands, riparian, grassland, and oak woodlands that could be eliminated by the project. Monitoring of mitigation efforts is necessary to meet Assembly Bill 3180 legal requirements and to identify needed changes in maintenance methods, evaluate the effectiveness and suitability of the restoration procedures, and broaden knowledge of habitat restoration procedures. Habitats to be mitigated include non-native grassland (191 acres), oak woodland (84 acres), riparian woodland/forest (16.1 acres), willow woodland (35.6 acres), freshwater marsh (0.9 acre), willow woodland understory (22.1 acres), and stream/aquatic habitat (16,050 linear feet). These habitats will be mitigated on an in-kind basis. Oak woodland, riparian woodland, and freshwater marsh habitats will be mitigated on a 2:1 acreage ratio; grassland and willow woodland habitats would be mitigated on a 1:1 acreage ratio. Stream/aquatic habitat (16,050 linear feet) will be mitigated on a 1:1 basis in conjunction with the riparian woodland enhancement and/or restoration. Hence, the required habitat replacement acreage is as follows: • Grassland 191 acres • Oak woodland 168 acres • Riparian woodlands 103 acres • Freshwater marsh 1.8 acres • Willow woodland understory 22.1 acres CAWINDOWSCESKrORMIT MON PLAN-ATA.DOC A-1 1-72 !achment A -fie Exhibit ATTACHMENT A MONITORING PLAN FOR HABITAT RESTORATION AND ENHANCEMENT SALINAS RESERVOIR EXPANSION PROJECT CITY OF SAN LUIS OBISPO November, 2000 • Streambed/aquatic habitat 16,050 feet (in conjunction with riparian woodland). The required habitat replacement acreage exceeds the impacted acreage because riparian and oak woodlands will be mitigated on a 2:1 acreage ratio. The net habitat gain will be 136 acres. Following project approval, the City will begin the HMP implementation. First, mitigation sites will be identified and purchased. Timing for site identification and purchase is estimated to take 1 year. Second site-specific, restoration/enhancement plans will be developed for each individual mitigation site and is estimated to take a minimum of 3 months total. Third, the site-specific restoration/enhancement plans will be implemented. Restoration and enhancement plans typically take 1 year to implement. Monitoring will occur both during construction activities and following site construction to document the degree of success or failure attained in achieving the performance objectives and to identify any needed remedial actions. Wetlands and grasslands will be monitored for a minimum of 5 years following site construction. The 5-year monitoring period is based on the assumption that the success criteria will be achieved within that 5-year period. If success criteria have not been met by the end of 5 years, monitoring will continue for additional years as needed to achieve the success criteria for 2 successive years. If achievement of success criteria at a mitigation site appears to be infeasible, a substitute mitigation measure, that achieves comparable habitat values, will be implemented. Monitoring will be complete when the City verifies in writing to agency resource staff that the performance standards have been achieved and no further mitigation is required. Riparian, streambed/aquatic, and oak woodland habitats will be monitored for a minimum of 10 years following revegetation. The 10-year monitoring period is based on the assumption that the success criteria will be achieved within 7 years after restoration/enhancement activities and sustained for 3 successive years without human intervention beyond scheduled maintenance activities. If success criteria have not been met by the end of 10 years, monitoring will continue for additional years as needed to achieve the success criteria for 3 successive years. If achievement of success criteria at a mitigation site appears to be infeasible, a substitute mitigation measure, that achieves comparable habitat values, will be implemented. Monitoring will be complete when the City verifies in writing to agency resource staff that the performance standards have been achieved and no further mitigation is required.

Performance standards for new and enhanced habitats are listed in Table A-1. These standards should be achieved 5 years after grassland or wetland habitat construction or enhancement efforts begin and 10 years after riparian or oak woodland habitat construction or enhancement efforts begin. If performance goals are not met, replanting and re-seeding, with continued monitoring and maintenance, will occur. Vegetation Performance Standards Vegetation performance standards represent values that document a trend toward the successful establishment of desired plant species and cover for each habitat. Cover values among the different habitats vary because of different growth patterns. Percent vegetation cover and plant species diversity will be measured at each site to determine success or failure. At least 80 percent of constructed and enhanced habitat acreage must meet the performance standards described for that habitat for the mitigation program to be deemed successful. Any portion of a mitigation site meeting the vegetation performance standard will be credited toward the acreage total. This performance standard will ensure that the mitigation program will provide more acreage than that permanently impacted by the proposed project, with a substantial net gain of habitat value (a net gain of 136 acres). No concentrations of weeds larger than 8 feet by 8 feet in diameter in wetland areas, and 200 feet by 200 feet in diameter in grassland, riparian, and oak woodland areas will be allowed. No more than 15 percent of the total vegetative cover may be dominated by invasive weedy species. Container plant and seedling survival will be assessed annually. If mortality occurs, replanting and/or reseeding, with continued monitoring and maintenance, will be required. Replanting and/or reseeding will occur annually, as needed. If performance criteria standards are achieved after 3 years and maintained for 2 years for the wetland and grassland restoration/enhancement areas, and after 7 years and maintained for 3 years for the riparian and oak woodland restoration/enhancement areas, the HMP will be considered complete and no further action will be required. If the performance standards are not achieved, replanting and reseeding will occur. Monitoring will continue for 2 years after the last plantings in CIWINDOWSIDESI(TOPUT MON PLAN-ATA.DOC A-31-74 Vtachment .A 'b Exhibit ('3� ATTACHMENT A MONITORING PLAN FOR HABITAT RESTORATION AND ENHANCEMENT SALINAS RESERVOIR EXPANSION PROJECT CITY OF SAN LUIS OBISPO November, 2000 wetland and grassland habitats and 3 years after the last planting in riparian and oak woodland habitats. Planted trees should have a minimum of 2 inches in basal diameter, be a minimum of 6 feet tall, have survived 3 years with no supplemental irrigation, and 2 years with no protection from herbivores. Understory must be comprised of a blend of native grasses and shrubs dominating 70 to 80 percent of woodland areas. In addition, at least 16,050 linear feet of enhanced or restored stream/aquatic habitat must be present in the riparian woodland. A restoration parcel may provide both stream restoration credit (in linear feet) and riparian restoration credit(in acres). Wildlife Performance Standards Although wildlife species and their use of the mitigation sites will be monitored during the 5- and 10- year monitoring periods, numerical performance standards are not specified. The vegetation performance standards guarantee that habitat requirements for wildlife will be achieved. 3.0 MONITORING METHODS Vegetation Methods Typical plant vegetation sampling methods will be used during the 5-year grassland and wetland monitoring period and during the 10-year oak woodland and riparian monitoring period. For example, plant species composition and percent cover will be determined for individual mitigation sites by placing transects with sampling plots throughout the site and recording relevant data, such as: • Plant cover, growth, survivorship and weed cover(all habitat types) • Hydrologic conditions (wetland and riparian areas only) • Oak, willow, sycamore, and cottonwood tree growth based on measurements of vigor, height, and diameter at breast height(oak woodlands and riparian areas only). • Percent cover of overstory to understory ratio (oak woodlands and riparian areas only). Monitoring will also occur within the entire mitigation site and will include recording relevant data such as: CAWINDOWSIDESKTORMIT MON PLAN-ATA.DOC A-4 1-75 Attachment A 4b Exhibit 8'9 ATTACHMENT A MONITORING PLAN FOR HABITAT RESTORATION AND ENHANCEMENT SALINAS RESERVOIR EXPANSION PROJECT CITY OF SAN LUIS OBISPO November,2000 • Removal and replacement of all dead and diseased planted species • Watering on a strictly "as needed" basis with gradual weaning schedule • Removal of invasive species • Placement, removal, and repair of plant protection devices Qualitative information about general site conditions (e.g., wildlife use, vegetation establishment trends, weed invasion, evidence and extent of erosion, and the need for remedial actions) will also be collected during the monitoring activities. Permanent photo-documentation points will be established at each mitigation site. They will be marked with T-bar fence posts that will be removed after completion of the monitoring period. Color photographs will be taken each year at the time of monitoring to qualitatively document plant establishment, hydrologic conditions, and other site conditions. The photographs will be included in the annual monitoring report to allow comparison between monitoring years. Monitoring will occur 4 times per year for 2 years and 2 times per year for each year thereafter. If plantings appear to be stressed, monitoring will be more frequent. Wildlife Methods Wildlife monitoring methodology is designed to document wildlife use of mitigation sites. The value of the mitigation site to wildlife can be determined by documenting wildlife use at the mitigation sites during the 5-year monitoring period in grassland and wetlands and 10-year monitoring period in oak woodlands and riparian habitats. Wildlife monitoring will occur during the years scheduled for quantitative vegetation monitoring Wildlife surveys will be conducted in spring and are intended to determine the species and type of activity at each mitigation site. Monitoring will consist of visiting a portion of the reference and mitigation wetlands to record observations of vertebrate and invertebrate wildlife species and estimates of the number of each species observed. Surveys will be conducted between sunrise and 11:00 a.m. when bird activity is highest. Surveys will not be conducted during periods of rain,high winds, or extreme cold, which severely inhibit wildlife activity and detectability. Evidence of wildlife use such as tracks, nests, and droppings also will be recorded. Wildlife monitoring methods will also include net-dipping of ponded areas in the mitigation wetland areas to determine possible use of the wetlands by amphibian species.

The annual monitoring period will be from January through September. The monitoring period will begin the first growing season following plant installation. Each monitoring report will detail the results of the monitoring for the previous year. The reports will provide a list of names, titles, and affiliations of persons conducting the monitoring and preparing the report and photographs taken of each mitigation site. Summary results of the previous years' monitoring will also be included in the reports. A final report will contain a quantitative analysis of attainment of performance standards at the conclusion of the monitoring program. The City will notify appropriate agencies when the final performance standards have been met. 5.0 MAINTENANCE ACTIVITIES AND REMEDIAL ACTIONS If the performance standards are not met following the 5 year monitoring effort in wetlands and grassland habitats and 10 year riparian and oak woodland habitats, the causes of failure to meet these performance standards will be determined and results will be reported to the resource agencies. Replanting or seeding will occur each year until the objectives are achieved. Monitoring will continue for 2 years after the last planting necessary to meet the above standards in wetland and grassland habitats and 3 years after the last planting necessary to meet the standards in riparian, stream/aquatic, and oak woodland habitats. Ongoing plant maintenance and weeding will occur throughout the monitoring period by the restoration contractor. Activities may include maintaining the irrigation system, maintaining the health of planted species, replanting and reseeding one time per year to ensure plant and seed establishment, and removing non-native invasive species. 6.0 CONTINGENCY PLANS Unforeseen circumstances may cause delays in the implementation of the restoration and enhancement activities, or may cause failure to meet performance goals in the proposed period of time for measuring success (i.e., 5 and 10 years after planting). Contingency actions for minor and major events are described below: CAWINDOWSTESKTORMIT MON PLAN-ATA.DOC A-E Attachment A '}a Exhibit ATTACHMENT A MONITORING PLAN FOR HABITAT RESTORATION AND ENHANCEMENT SALINAS RESERVOIR EXPANSION PROJECT CITY OF SAN LUIS OBISPO November, 2000 Container Plant Damage and Poor Seed Germination Due to Drought Conditions In the event that severe drought affects the integrity of the newly planted mitigation site, the City or their revegetation contractor must ensure that imported water is available for irrigation use. Erosion Due to Excessive Rainfall In the event that excessive rainfall and runoff at a mitigation site jeopardize the integrity of the newly-planted mitigation site, the City or their revegetation contractor must repair erosion control devices and take other measures to ensure protection of the revegetated areas. If the erosion causes significant damage to any part of or all of the mitigation site such that applicable performance goals are not met during the 5- and 10-year monitoring periods, the City will revegetate the affected areas. Damage to Mitigation Sites Due to Fire In the event that fire causes damage to any part of or all of the mitigation sites, replacement planting would not be required. Poor Plant Establishment or Growth Diseased plants or unsuccessfully seeded areas will be replanted or reseeded on an annual basis during the monitoring period. In the event that plant establishment and/or seed germination performance fails to meet half of the quantitative performance goals during either (1) the 5-year monitoring period for grassland and wetland restoration/enhancement, or (2) the 10-year monitoring period for riparian and oak woodland restoration/enhancement, the City will reseed or replant as necessary. If the goals are not met for either (1) 2 consecutive years in the grassland or wetland areas, or (2) 3 consecutive years in the riparian or oak woodland areas, the City will contact the involved agencies and present a contingency revegetation plan. The contingency plan will identify the causative factors and provide remedial action to increase plant establishment, seed germination, and/or vegetation growth in the affected areas or to undertake mitigation at an alternative site.

Box 100 Alliance (CSPA) Sacramento, CA 95812-0100 1586 La Cita Court, Chiefs fax no.: 916-657-0932 San Luis Obispo, CA 93401 805-5449741 (home phone) 11 756-2505 (work phone) September 17, 2000 Subject: Following are my comments as a fish and wildlife biologist for CSPA relative to CSPA's participation rights to comment on the State Water Resources Control Board (SWRCB) Draft Order "WR 2000-_" of 8/24/2000 titled "In the Matter of the Petition for Extension of Time of the City of San Luis Obispo Permit 5882 (Application 10216)" regarding San Luis Obispo City's Proposed Salinas Reservoir Expansion Project. Dear Mr. Baggett: I appreciate the opportunity to provide comments on behalf of CSPA on the Subject SWRCB Draft Order of 8/24/00 (hereafter referred to as Draft Order). I provided my fish and wildlife biologist specialist/professional qualifications statement to the SWRCB for its October 12, 13, and 18, 1999, hearing that provided the basis for the SWRCB Draft Order of 8/24/00. I also provided similar personal professional informations to the SWRCB in CSPA Exhibits BB and DD submitted and accepted at the October 1999 hearing. So I will not recover that personal vitae here. I will now comment on the SWRCB Draft Order in 3 sections: (1) legal issues, (2) issues downstream of the Salinas Dam, and (3) issues upstream of the Salinas Dam. I. Legal Issues: As others representing CSPA are attornies, I will not go into great detail on several legal concerns. But I do want to bring these issues up for the record as the timeframe provided by the SWRCB has made it difficult for CSPA representatives to fully coordinate our comments on the Draft Order. A. The City Did Not Use Due Diligence in putting the Project Water to Beneficial Use- The SWRCB claims in the Draft Order that the City has shown due diligence since the completion of the Salinas Dam in 1942 to put the Reservoir's entire water supply to beneficial use. The Dam's 19' high gate was not installed by the U. S. Army Corps of Engineers (hereafter referred to as the Corps) when the Dam was built due to seizmic safety considerations. However, the SWRCB's claim that the City has shown due diligence in the subsequent 58 years since the Dam was completed to put the entire Project water to beneficial use is unfounded. The SWRCB makes this claim by stating "San Luis Obispo has diligently pursued the reservoir expansion by taking 2 actions to facilitate a property transfer between the.Corps and a local entity, to resolve the issue of duplicate permits, to identify project funding, and to comply with CEQA." (page 15, paragraph 2). No one that I know of is questioning that the City has shown due diligence throughout the 1990's to attempt to put the Project's entire water supply to beneficial use. However, except for unsupported statements by the City, the Draft Order refers to no evidence, other than in the 1990's, that any of the above quoted diligent steps took place prior to 1990. Regarding these unsupported City statements the Draft Order states "Witnesses for San Luis Obispo testified that there were a number of meetings between the Corps and San Luis Obispo, and at times, the County, between 1971 and 1999 to resolve the issue of which local entity should acquire the facilities." (page 15, paragraph 2). This statement does not prove that any of these meetings took place prior to 1990. And even if one or a few meetings of possibly a few hours each did take place prior to 1990, that alone could not represent due diligence on the part of the City to put the entire Project water supply to beneficial use over a 48-year period from 1942 to 1990. To the contrary, all of the evidence referred to in the Draft Order proves that only in the 1990's did the City use diligence to put the entire Project water to beneficial use. The Draft Order demonstrates the simple issue of resolving the duplicate permits was stipulated to in 1995 (page 15, paragraph 3). And the Draft Order demonstrates that Project funding and CEQA compliance efforts were all not acted on until "the years between 1993 and 2001." (page 16, paragraph 2). If the standard established by the SWRCB for a jurisdiction to show due diligence to put a projects' water to beneficial use over a 58 year period is maybe at most have one or a few meetings about the project over the first 48 years of the project, then the SWRCB is making a mockery of the due diligence concept. What the SWRCB should do in this case is to modify the Draft Order (1) to void the City's existing Permit 5882 for the City failing to show due diligence over a 58-year period to put the Salinas Reservoir entire water supply to beneficial use and (2) to, therefore, disapprove the proposed Project, and (3) to take no further action on the Project, unless the City chooses at a later date to apply for a new permit. B The SWRCB Has Turisd+_ction to Determine the Legal Adequacy of the ER: Several places in the Draft Order the SWRCB makes statements similar to "the SWRCB does not have the authority to make a determination concerning the legal adequacy of San Luis Obispo's EIR." (page 11, paragraph 1 and page 22, paragraph 2). This is a tactic used by the SWRCB in the Draft Order to justify approving the Project, which the Draft Order does (page 21, paragraph 1), while admitting in the Draft Order that the ER is inadequate (page 31, paragraph 2, and page 32, paragraph 4). It is obvious, without my quoting either from CEQA or CEQA case law, that a responsible public trust agency (which the SWRCB is, page 21, paragraph), that has the authority to approve or disapprove a project based on the environmental adeqaucy of the ER, clearly 3 has the legal authority to make a determination on the legal adequacy of the EIR, as well as its environmental adequacy. On the one hand, the SWRCB needs to be commended for coming to the correct conclusion that the EER is inadequate in concluding the Project will not have significant adverse impacts on steelhead downstream of the Salinas Dam (pages 31 and 32). On the other hand, it is untenable for a trust agency as the SWRCB to assert that whenever a trust agency determines that an EIR is inadequate, it has to approve the project because under CEQA (or any other public trust law) it has no authority not to approve the project. By asserting this the SWRCB is even more untenably asserting that whenever the SWRCB, or any other responsible California trust agency, concludes in their administrative proceedings that an EIR is inadequate, the public must take the trust agency to court to prove the trust agency's admission the EIR is environmentally inadequate is the same thing as the trust agency admitting the EIR is legally inadequate under CEQA. The courts would be clogged to a standstill if every California public trust agency made the same assertions the SWRCB does here, in turn forcing the public to use the courts in every instance to get trust agencies to do what CEQA requires them to do— rule on the legal as well as the environmental adequacy of the EIR, which for all practicle purposes is the same thing under CEQA. In unfortunately coming to the wrong conclusion in the Draft Order that the SWRCB has no authority to rule on the legal adequacy of the San Luis Obispo City (hereafter referred to as the City) EIR, the SWRCB only addressed Paso Robles position that the EIR is inadequate (page 10, bottom, and page 11, top). The Draft Order does not address CSPA's major position that the EIR is grossly inadequate in many areas and a Supplemental EIR (SEER) needs to be done before the SWRCB considers approving the Project. For Example, in my written comments for the October 1999 hearing on the Project and the adequacy of the City's EIR (.CSPA Exhibit BB), I covered a spectrum of issues where the EIR was inadequate and the SWRCB therefore needed to require that the City do a SEIR before proceeding further with the Project. I repeatedly made this recommendation to the SWRCB in CSPA Exhibit BB after extensive discussion of each major issue where the EIR was inadequate[ After extensive discussion in CSPA Exhibit BB of each major environmental issue where the EIR was inadequate, I made the recommendation in the following places in CSPA Exhibit BB that the..SWRCB require that the City do a SEIR before the SWRCB proceeds further with the Project: (1) cumulatively significant adverse impacts with other projects, page 4; (2) cumulatively significant adverse downstream flow impacts of the existing Salinas Dam combined with the proposed Project to raise the Salinas Dam 19', page 6; (3) significant adverse downstream flow impacts caused by the proposed Project by itself downstream of the Dam, pages 12, bottom, page 13, top half, page 22, and (4) significant adverse environmental impacts upstream of the Dam, page 25. Nowhere in the Draft Order that I saw does the SWRCB address these recommendations by CSPA to require the City to do a SEIR on these issues very inadequately covered or not at all covered in the original EIR, before the 4 SWRCB proceeds furhter with the Project. In fact, of the many issues CSPA brought up in written, oral, and exhibit testimony and evidence at the October 1999 SWRCB hearing, the only CSPA issue that is partly addressed in the Draft Order, relative to the SWRCB requiring more information from the City than is in the existing EIR, as I previously covered herein, is the likelyhood the proposed Project would have significant adverse impacts on steelhead and their habitat downstream of the Salinas Dam (page 31 and 32). But instead of the SWRCB requiring the City to do a SEiR on this issue once flow studies are done for the 14.3 mile Salinas River Canyon stretch of the River immediately downstream of the Dam, the Draft Order merely says that after the SWRCB has approved the Project the City needs to study the proposed Project impacts on steelhead and their habitat in this stretch of the River. Based on the foregoing discussion, what the SWRCB should have done, in part based on the SWRCB concluding the EIR is inadequate, is require that the City do a SEIR on all the issues discussed above that were very inadequately or not at all addressed in the existing EIR before the SWRCB proceeds further with the Project. That is still what the SWRCB needs to do relative to the CEQsA issues. This concludes the Legal Issues section of my comments on the Draft Order. However, the SWRCB should consider that all my subsequent comments on environmental and ecological issues downstream and upstream of the Salinas Dam relative to the Draft Order have legal as well as administrative significance. H. Issues Downstream of Salinas Dam: As I stated previously, the SWRCB is to be commended for coming to the conclusion in the Draft Order that the Proposed Project, contrary to the conclusion of the EIR, could have significant impacts on steelhead and the riverine ecosystem they are reliant on downstream of the Dam (page 31 and 32). The SWRCB primarily comes to this conclusion based on the EIR using average annual hydrological data instead of monthly hydrologic data to conclude from (page 32, paragraph 4). The SWRCB then concluded in the Draft Order that monthly Dam spill figures (which the EIR contained) are better than annual averaged Dam flow release figures for analysing to make conclusions about the Project's adverse impacts on steelhead and the downstream Salinas River ecosystem (page 33, paragraph 2). . The SWRCB then made this analysis of the EIR monthly spill data and concluded in the Draft Order "SWRCB staff has prepared Table 1 (attached), which examines the project's impacts on a monthly basis, and which demonstrates that the project may indeed have an impact on steelhead if they are present." (page 33, paragraph 2). However, the SWRCB first grossly simplifies and then therefore wrongly concludes in the Draft Order that "CSPA's other analysis provides a single value obtained by averaging 52 years of data (CSPA BB.) This does not provide the level of specificity needed to analyze impacts." (page 25, paragraph 2).. CSPA exhibit BB is my written comment letter submitted and accepted for the SWRCB hearing of Oct. 12, 13, and 18, 1999, on the proposed Project. In my multi-paged analyses of the hydrologic data in the M1 I did use some annually averaged figures for the long period since the Project was built in 5 the early 1940's. I did this to show that, contrary to the EIR's conclusuion the Project would not significantly impact steelhead and their downstream Salinas River ecosystem, one could use annually averaged figures generated from the E1R data to come to the opposite conclusion that the Project would have significant adverse impacts on steelhead and their Salinas River ecosystem downstream of the Dam. These analyses I made are still valid since spills, which the SWRCB uses in the Draft Order to show the proposed Project could have significant impacts on steelhead and their habitat downstream of the Dam, are only one source of Salinas River water the Dam Project impacts. As I discussed in CSPA Exhibit BB, spills from the Dam occur so rarely (about one third of the years) and in so few months in the years they do exist, that spills from the Dam are not adequate to maintain the sustainable existence of steelhead downstream of the Dam (CSPA Exhibit BB, page 8, bottom, page 11, bottom, and page 12, paragraph 12). I agree with the SWRCB conclusion in the Draft Order that spill data shows that the proposed Project would have significant adverse impacts on steelhead and their Salinas River habitat downstream of the Dam. But the SWRCB needs to acknowledge that these spills are so infrequent due to the existing Dam, and will be less frequent and intense with the proposed Project raising the Dam 19", that constant operational water releases from the pipes at the bottom of the Dam, and not rare Dam-topping spills, are what is needed to maintain a sustainable population of steelhead downstream of the Dam. The SWRCB's reliance to date on the 1972 "lave Stream Agreement" (ISA) that provides that a mere trickle of water visible in the Salinas River downstream of the Dam is presumptive proof steelhead and other aquatic species survival, maintenance, and restoration needs and requirements are being met is environmentally and ecologically unacceptable. Especially when promulgated by of a California trust agency as the SWRCB. Nearly my entire hydrological flow analyses in CSPA Exhibit BB (pages 8 through 17) of the adverse impacts the existing Dam has and the proposed Project of raising the Dam 19' would have on steelhead and their River habitat in the Canyon downstream of the Dam is based on the very inadequate flows released from the Dam pipes that meet the absurd "visible trickle" requirements of the ISA but do not meet the requirements of steelhead to sustainably survive in the River downstream of the Dam. So, I strongly object to the SWRCB Draft Order ignoring or rejecting my important hydrological flow analyses mostly made from the existing EIR data that demonstrates that the pipe flow releases from the Dam to meet the ISA requirement of a visible trickle in the River are very inadequate to meet the survival, maintenance, and restoration needs of threatened steelhead and other aquatic species downstream of the Dam. The danger of the SWRCB using only rare monthly spill data in the Draft Order to conclude there could be a significant impact on steelhead and their River habitat downstream of the Dam, is that the SWRCB may ultimately try to use a modification of rare spill events to then conclude the proposed Project would not have a significant impact on steelhead and their habitat. Whereas, the obvious is that no matter how rare spill events might be modified by the City's operation of the Dam, spill events can never by themselves or in combination 6 with the currently inadequate LSA meet the survival, maintenance, and restoration needs of steelhead downstream of the Dam. These steelhead needs must be met with steady flows on a daily, hourly, and minutely basis being released from the Dam pipes through operational changes of the existing Dam operation proceedures. In my written comments in CSPA Exhibit BB, I provided the SWRCB with extensive discussion and supplemental CSPA exhibits to show that a monthly- averaged analysis of flows below the Dam, whether spill data or flow release data, is inadequate by itself to show if there is or is not water being released from the Dam on a daily, hourly, and minutely basis to keep steelhead and other fish and aquatic species in good condition below the Dam as required by Fish and Game Code Section 5937 (CSPA Exhibit BB, pages 14 and 15). Supplementing this discussion were 4_photographs. I referred to that I took 4/23/99 on the Salinas River in the Salinas River Canyon about 5 miles below -thie Salinas Dam on Mr. Otto Schmidt's property. These shotographs showed that virtually no water was being released from the Dam (2 photos on page 2 of CSPA Exhibit Of, and photos 1 and 2 of Exhibit 2 of CSPA Exhibit DD, my comment letter justifying the preservation of CSPA's Environmental Protest against the proposed Project). This evidence was further supplemented by my discussion in CSPA Exhibit BB (pages 14 & 15) of daily flow data CSPA obtained from San Luis Obispo County conclusively proving that for that date of 4/23/99,_the City-only released 0.07 cfs (cubic feet per second) from the Dam liereas 11.6 cfs was flowing into the Salinas Reservoir for the day of 4/23/99 (CSPA Exhibit K). This discussion in CSPA Exhibit BB further pointed out that for the critical water flow period of the entire months of March and April, 1999, while 27 cfs on average flowed into the Reservoir, the City only released 0.07 cfs for the entire 2 months. Under no system of analysis and measurement, "Live Stream Agreement" or any other, can a 0.07 cfs flow release from the Dam represent adequate flows to keep steelhead and other fish and aquatic species in good condition as required by Code Section 5937, the Federal and State Endangered Species acts, CEQN, NEPA, or any other public trust law. Based on the foregoing discussion, the SWRCB must not ignore or reject my extensive monthly and daily hydrologic flow analyses in CSPA Exhibit BB. This is especially important because my above discussed flow analyses in CSPA Exhibit BB support the SWRCB conclusions in the Draft Order that (1) the proposed Project could have significant impacts on steelh6A and their habitat in the Salinas River downstream of the Dam (pages 31 and 32) and (2) more studies need to be done to determine the proposed Projects impacts on steelhead and their habitat downstream of the Dam (page 32, paragraph 2, and page 33, paragraph 4). However, this is where my support of the SWRCB Draft Order ends relative to the direction the SWRCB is taking in the Draft Order to have such fisheries/flow studies performed. Therefore I request that the SWRCB modify the Draft Order to do the following. First as I previously discussed under Legal Issues, the SWRCB needs to modify the Draft Order to require the City to do these fisheries/flow studies now and incorporate them and their results into a SEIR before the SWRCB proceeds any further with the proposed Project. Second. the SWRCB needs to modify the Order to require that the City do these fisheries/flow studies under the close supervision and coordination of the National Marine Fisheries Servive (NMFS) and Calif. Dept. of Fish and Game (CDFG). How can the public or the SWRCB have any confidence that the City will do these studies in a manner to find, protect, and restore steelhead in their Salinas River Habitat below the Dam, when it has already done an EER inappropriately biased to prove steelhead do not exist below the Dam in numbers worth saving or in habitat worth protecting and improving for steelhead recovery. The irony with these City EIR conclusions is that it is the City's existing Salinas Dam Project that has primarily so impacted steelhead in the Salinas River that they are now a Federally threatened species in the Salinas River. And yet the City through its biased IIR wants the public and trust agencies to buy into its perspective that when a jurisdiction as the City primarily causes a species to be listed as threatened it then is so rare as to not be worth protecting and restoring to greater numbers. Yet this is the City's position in their existing IIR. They therefore clearly cannot be trusted to do, without pre-bias against Salinas River steelhead and their habitat, the fisheries/flow studies the SWRCB requires them to independently do in the Draft Order. The Draft Order needs to be modified to require the City to do the fisheries/flow studies under the supervision of and coordination with the NMFS and CDFG. Third. It is totally inappropriate for the SWRCB in the Draft Order to state: "The SWRCB finds that if steelhead are present in the reach between the Salinas Dam and Highway 58 . . . . a geomorphologic study would be necessary to identify what stream flows are required for maintenance of the river channel downstream of the Salinas Dam." Just about anyone involved with the proposed Project and familiar with this stretch of the River knows that due to the existing Salinas Dam operation by the City, flows are so inadequately provided to this stretch of River that steelhead of any age class will only be found there under extra-ordinary weather conditions that generate enough rain long enough downstream of the Dam to overcome the City's existing unacceptable operation of the Dam. It is well known that the building of Salinas Dam and the City's operation of it relative to inadequate flow releases, including the period since the ISA was promulgated in 1972, has caused steelhead to decline to the point of being threatened with extinction from the Salinas River (CSPA Exhibit BB, page 21). So I and anyone else including the SWRCB should expect at any given time it is more likely that steelhead will not be found, rather than be found, in this reach of the River. That does not mean that with adequate and appropriate flow releases to the Salinas River from the Salinas Dam, steelhead will not recover in the Salinas River to the point they could be considered no longer threatened with extinction from the Salinas River. So the goal of the initial fisheries study required by the Draft Order must not be to necessarily find steelhead before the flow studies are required. But instead the goal of the initial fisheries study under NMFS and CDFG supervision must be to determine 8 only if the 14.3 mile Canyon reach of the River immediately downstream of the Dam is suitable recovery habitat for the steelhead. Therefore the SWRCB needs to modify the Draft Order to state that the studies need to be done on I for the purpose of determining if the 14.3 mile Canyon stretch of the Salinas River immediately below the Dam is adequate habitat for steelhead for survival, maintenance, and recovery, if adequate and appropriate water flows are released to the Canyon stretch of Salinas River. Four. for the SWRCB to comply with its Draft Order statement of responsibility, relative to State waters and species reliant on it, to "in the public interest and to protect public trust uses" and "in furtherance of the SWRCB's continuing authority and duty of continuing supervision, under the public trust doctrine, over all Salinas Reservoir diversions" (page 34, footnote 24) the SWRCB needs to modify the Draft Order to require the City to provide interim flow releases adequate to keep steelhead and other fish and aquatic species alive and in good condition downstream of the Dam. Not to do this would be illogical. Why would the SWRCB (1) on the one hand in the Draft Order require a study to attempt to find steelhead in the 14.3 mile Canyon reach of the River below the Dam, and (2) on the other hand in the Draft Order allow the City to continue releasing flows, or no flows much of the time, nearly guaranteeing steelhead will not be found there unless extraordinary rain-yielding weather conditions happen to exist when the study is done? The only purpose I can understand for the SWRCB allowing these 2 opposed conditions to exist in the Draft Order is to help ensure the City does not find steelhead in the Canyon reach of the River. I hope that this is not the SWRCB's purpose for not requiring interim Dam flow releases to begin as soon as possible, which should be before this coming rainy season to increase the chances the fisheries study will find steelhead. CSPA attorney Ms. Lorraine Scarpace and/or CSPA fisheries biologist Mr. Felix Smith are providing the SWRCB with Draft Order comment recommendations for interim flow releases from Salinas Dam to keep steelhead and other fish and aquatic species in good condition until the Draft Qrder required fisheries and flow release studies are done and resultant long-term flow releases are put into effect. These flow recommendations by CSPA are only meant to provide interim flows until the studies generate the appropriate long-term flow regime needed. CSPA's fisheries specialists do not 100% agree on the regime of our recommended flows and that is a healthy minor disagreement which acknowledges that only the proper fisheries and flow studies, open to interested parties for review and comment, can generate the necessary long- term flow release regime for steelhead survival, maintenance, and recovery in the Salinas River downstream of the Dam. But what CSPA fisheries specialists do 100% agree on is that the interim flow regime CSPA is recommending to you is vastly superior for steelhead and their Salinas River habitat downstream of the Dam than the inadequate and often non-existant flow releases the City has done in the past and present under the very inadequate ISA! 9 Before I leave this section of my comments titled Issues Downstream of Salinas Dam. I will recover my discussion in CSPA Exhibit BB on the importance of the 14.3 mile Canyon stretch of the Salinas River immediately below the Salinas Dam to the survival and recovery of steelhead in the Salinas River (CSPA Exhibit BB, pages 6 & 7). Other than enormous flow reductions to this Canyon stretch of River from the construction of the Salinas Dam and its flow release operation ever since by the City, this stretch of River has had little of the human development impacts to it that almost all other downstream reaches of the River and its tributaries have had since the Dam was built in 1942. This River stretch has relatively few land owners living along it and it is otherwise remote with the Canyon terraine being steep, rugged, and generally inaccessible to people and development, unlike nearly all other areas of the Salinas River System. The Dam cut off the headwaters of the Salinas where steelhead would have historically migrated and spawned. And tributaries to the Salinas River below the Dam are more and more rapidly being robbed of their flows by developments diverting their surface flows and pumping their underflows. Most unfortunate for steelhead that spawn in these downstream tributaries has been the rapid expansion of Grapescape in San Luis Obispo County. Most of the County's 20,000 acres of Grapescape have been planted in the last 10 years and more 1000's of acres are being planted every year. Many of the historical Salinas River steelhead spawning streams pass through the hill lands which were once ranchlands and are now becoming more and more exclusively water guzzling Grapescape. The impact of this Grapescape in historical steelhead spawning habitat can only be reasonably guessed at— because no "trust" agencies that I know of, including the SWRCB, have the trusted will to analyze and study this water guzzling impact in steelhead spawning and rearing habitat. But there can be little doubt that this hill land, water guzzling Grapescape, where only recently ranches existed, is sucking steelhead spawning streams dry! There have been many other adverse development impacts on the water supply of steelhead spawning Salinas River tributaries; Grapescape is just the enormous most recent ongoing adverse impact. Old timers in the County who are now dying off so the stories cannot be so well remembered and told, themselves remember and tell of when many of the tributaries to the Salinas River had plenty of water for steelhead to spawn in. Whereas now these old timers tell how many of these streams have little or no water left in them for steelhead spawning, hatching and rearing. And these old timers believe and tell that it is due to all of the human water using developments along these streams that they are going dry and many are thus no longer suitable for the steelhead life cycle. The bottom line for steelhead is that due to all these difficult to control adverse development impacts along Salinas River tributaries, their spawning habitat has greatly diminished. And it is likely more rapidly than ever continuing to diminish, especially because of all the new Grapescape developing in the historical hill land stream spawning habitat of steelhead. 10 I believe the best major hope for recovery of steelhead in the Salinas River is the 14.3 mile Canyon stretch of the Salinas River where little of these stream tributary types of water guzzling development activities can occur. Before the Salinas Dam was built and much of the Salinas River's flows were diverted, the Canyon stretch of the River would likely not have usually been suitable spawning habitat. Winter flows in the Canyon stretch of the River would typically have been too high and powerful for successful steelhead spawning activity. However, before the Dam was built, high flows prohibitive to steelhead spawning would not have been significant. Steelhead would have just passed through the turbulant Canyon waters to their natural headwater spawning areas upstream of the Canyon. But with the building of the Dam two things happened. First, the steelhead lost their headwater spawning areas for all time, or until the Salinas Dam is ultimately removed. Second, because the Dam blocked off much of the turbulant historical winter flows, the Canyon became a kind of defacto or even surrogate steelhead spawning and rearing area. Where there were once mostly turbulant rapids and raging pools in the Canyon in the winter, with the Dam there were now alternating riffles, slicks, and pools much of the time in the winter. Ideal habitat for not only spawning steelhead, but also hatching and rearing juvenile steelhead. But there has been a major problem and obstacle with the Canyon stretch of the Salinas River becoming a significant spawning and rearing habitat for steelhead. Due to the City's unacceptable operation of the Dam relative to releases to the River, even in the winter months there often has not been enough flow in the Canyon stretch of the River for steelhead in most years to migrate to and spawn in. Then, even if enough flows existed in the winter for steelhead spawning to occur, the City releases so little if any water to the River during much of the spring hatching and the summer rearing seasons that juvenile steelhead survival in the Canyon stretch of the River would typically likely be very low. That is why, if steelhead are to have the best chance for recovery in the Salinas River, somewhat artificial though it may be due to construction of the Dam, the Canyon stretch.of the Salinas River must from now on be treated as a spawning and rearing habitat for steelhead. And of absolute importance for this steelhead restoration to successfully happen, flow releases from the Salinas Dam must from now on be managed to allow and enhance in this Canyon reach of the River (1) adult steelhead migration to it and over any of the 5 illicit private dams in the Canyon, (2) steelhead spawning in this reach, (3) steelhead egg hatching in this reach, (4) juvenile steelhead rearing in this reach, and (5) juvenile steelhead migration from this reach to the ocean. For number "(4)" above to occur, adequate flows must be released in the summer and fall low flow seasons for juvenile steelhead to be able to stay in the protective riffle areas where they can successfully avoid large native and non-native predatory fish. CSPA's recommended interim flow release regime for the low flow season should adequately provide these juvenile steelhead rearing protective flows from predatory fish. For number "(5)" above to occur, CSPA's interim flow regime may not be adequate in some years. One of the concerns of juvenile steelhead successfully migrating to the ocean is having enough water to do so. In a year where 11 significant rains of about an inch or more start earlier than November 15, when CSPA's recommended interim flows increase from the low flow season recommended minimum, steelhead could migrate out of the bedrock underlain Canyon reach where water does not rapidly disappear downward from the stream bed. However, once these juvenile steelhead migrate out of the Canyon area into the broad expanses of the sandy Salinas River bottom where water can rapidly disappear into the sand, they could become stranded and die. In this situation of rain occuring before November 15, juvenile steelhead could begin migrating out of the Canyon on as little as about a 1" rain storm. This is because the Canyon reach is steep, narrow, and mostly bedrock underlying this soils, all of which can lead to fairly high flows flashing out of the Canyon on a single rain storm of about 1". Last year Cal Poly University fisheries professor emeritus Dr. Richard Krejsa told me he was doing some fisheries investigative work along San Luis Obispo Creek in San Luis Obispo City when the early November rain of about 1" hit. He said this caused about a 15" rise and fall of the Creek over a few hour period. San Luis Creek in the City is only a couple of miles downstream of its headwaters in Cuesta Canyon which has the same steep, narrow, bedrock underlain conditions of the Salinas River Canyon. I reveal my conversation with fisheries biologist Dr. Krejsa hereto get us all thinking ahead of time that if juvenile steelhead in some years migrate out of the Canyon reach on rain induced flows occuring earlier than typically expected, a flow release regime strategy needs to be worked out in advance to ensure these juvenile outmigrants do not get stranded in the "Big Sandy" early in the rain season only to dessicate and die there. Such a situation could have happened last year if there were any outmigrant juvenile steelhead because that significant 1" rain in early November was not followed by any other significant rains until late in the winter, several months later. Any juvenile steelhead migrating out in early November could have been stranded and died in the downstream sandy Salinas River before these later rains arrived providing more outmigrating flows. In this not normal but still fairly often occuring rain/flow pattern, a Salinas Dam flow release regime would need to be utilized that either (1) kept early outmigrant juvenile steelhead alive in the downstream sandy areas of the River until more rains arrived or (2) provided enough flows, but for a likely shorter period, for juvenile outmigrants to swim downstream to the confluence with the Nacimiento River where incoming Nacimiento River flows would likely be adequate to keep juvenile steelhead alive until more rain inducing outmigrating flows occurred. Whatever the unique or not unique situations might be for using the Canyon stretch of the Salinas River for Salinas River steelhead recovery, they need to be recognized or discovered and dealt with. For I know of no other way nor have no other hope for steelhead recovery in the Salinas River than this reasonable plan involving the Canyon reach of the Salinas River. But adequate and appropriate flows must be released from the Salinas Dam for this recovery plan to work, and in the long past since the Salinas Dam was built and currently under the "Live Stream Agreement" these flows have not been released and are not being released from the Salinas Dam. 12 1Il. Issues Upstream of Salinas Dam: Because I do not have a current copy of CEQA I cannot completely challenge the RWQQB's conclusions in the Draft Order that regarding the adequacy of the City's EIR: "it is unnecessary for San Luis Obispo to identify every detail of its proposed mitigation" and "Under the CEQA Guidelines, mitigation measures may specify performance standards that would mitigate the significant effects of a proposed project and that may be accomplished in more than one specified way. (Cal. Code Regs., tit. 14, section 15126.4, subd. (a)(1)(B).)" (Draft Order, page 38, paragraph 2). However, this must be a fairly new CEQA code section because it goes against the CEQA case law that I am familiar with. I do not have time to find and quote any of these CEQA cases, but they say that before an agency approves an EIR the actual mitigations in it must be specified so that the public and other reviewers can determine from the EIR that the mitigations are or are not adequate, and can therefore comment on them, and file court proceedings against the EIR certification/approval agency if the mitigations in the EIR are inadequate. How would the public ever know if the actual mitigations were adequate or not and therefore could comment on them and file legal action against them if they were not adequate if the actual mitigations were not required to be delineated in the EIR? When the City certified their Final EIR in June 1998, the City did not know where any mitigations would be located for the proposed Projects's significant impacts upstream of the Dam on 73 acres of oak-pine woodlands (2500 oaks of various species and 470 grey pines), 74 acres of wetland/riparian woodland habitats (estimated by myself and other environmentalists [since the City refused to count riparian tree losses for disclosure in the EIR] to be as many as 100,000 willows and other riparian trees of various sizes), about 16,000 feet (about.3 linear miles) of Salinas Reservoir feeder stream channel impacts, and chaparral habitat. And today, over 2 years later, as the Draft Order demonstrates (pages 35 to 38), the City still does not know where any of the mitigation sites will be for the many significant impacts the EIR admits the proposed Project would cause to extensive stream and upland habitats upstream of the Dam. This nearly total lack of knowledge by the City where its mitigation sites will be 2 years after certifying the FEIR is a far cry from the SWRCB saying in the Draft Order "it is unnecessary. for San Luis Obispo to identify every detail of its proposed mitigation" (page 38). The SWRCB has in its Draft Order inappropriately tentatively approved the City's proposed Project not only without knowing "every detail" of the City's EIR mitigations but without knowing anv detail of the City's mitigation sites! If this is what CEQA allows under the code section the SWRCB cited in the Draft Order, then relative to meaningful mitigations and the publics rights to administratively and legally challenge EIR "mitigations", then CEQA is virtually worthless for the use of mitigations to reduce project adverse environmental impacts to a level of insignificance. 13 The public would never have a clue what the EIR's final mitigations were because they would be chosen, as in this case, years after the EIR was certified, and in some cases, as in this case, on private land where the public would have no right to visually review the mitigation sites compounding the fact the public never had an opportunity to review the sites in the ER because none were specified at the time of certification. The whole mitigation scenerio the SWRCB sets forth in its Draft Order to justify approving the Project without itself knowing where any of the mitigation sites will be is outlandish. Actually, apparently unknown to the SWRCB as evident from its discussion of Upstream Water Resources Impacts and Mitigation Measures in the Draft Order (pages 35 - 38), on 3/7/00 the City Council did approve funding for one totally inappropriate "mitigation" site 15 miles from the proposed Project's Dam impact sites and arguably not-in-kind habitat. This site is 49 acres of very steep hillside land adjacent to Cal Poly University. The 2/29/00 Council Agenda Report and Council Agenda on the "mitigation" site states "The property has considerable potential for oak woodland mitigation that will be needed in relation to either the Salinas or Nacimiento projects" and the site will be purchased with funds from the "Salinas Reservoir Mitigation Program" (pages C7-1 and 4, attached). The SWRCB should pay particular attention to the fact that, as the Draft Order indicates (page 36, paragraph 2), the EIR Habitat Management Plan (HMP) indicated that the City would.place its highest mitigation priority on acquiring mitigations sites near the areas of Project impacts around the Salinas Reservoir and upstream of it. But in the City's apparently first endeavor to acquire a mitigation site for the Project, it failed miserably to do what it said it would do in the HMP and bought an inappropriate "mitigation" site 15 miles from the proposed Project impact areas. This is not good initial evidence that the City is going to honor its HMP promises and acquire mitigation sites close to the Project impact areas. The concept of placing the highest priority on mitigating in the immediate area of the Project adverse impacts is environmetally/ecologically well founded It is based on plant and animal species that use the project site are the ones that are impacted by the project. Therefore, for their best chances for survival they need to be mitigated for in the area where they live. A mitigation site 15 miles from the areas that will be adversely impacted by the proposed Salinas Dam Project will not mitigate the impacts on species living in and around the Salinas Reservoir. Furthermore, although I may have overlooked it or forgotten it, I do not recall the EIR indicating, as the Draft Order indicates (page 36, paragraph 2), that if the City cannot find mitigation sites around and upstream of the Reservoir as the HMP indicates it would, it will take the approximately.$10,000,000 it has ear-marked for Project mitigation and give it to agencies and private parties in a money give-away contest. If you want to make voters and constituents and the public and agencies happy, then give them money. But this buying of the public's silence does not in any way mitigate for the wild species that lose their homes, habitat, health, and lives from the adverse environmentaVecological impacts of a project. Such "mitigation" money handouts to agencies and the public thus buying off their citizenship trust responsibilities is destroying other species and their 14 rights to survival. The SWRCB as a trust agency should never forget the inappropriateness of this disgraceful "mitigation" tactic,which is as of recent destroying all the environmental and ecological premises upon which mitigation has heretofore been rightfully founded and enacted on. And one of the most disgraceful of all such agency and public buyoffs was the Regional Water Quality Control Board earlier this year allowing PG&E to make an upland public park out of land surrounding the Diablo Canyon Nuclear Power Plant. But this is to absurdly mitigate for the billions of gallons of cooling tower hot water dumped daily into a cold water marine environment for the past 15 years. And in turn this has caused enormous deadly adverse impacts to the marine environment invertebrates, fishes, mammals (dying in large numbers from warm water red tied poisoning likely enhanced by the huge plume of Diablo Canyon hot water outfall into the ocean), and plants. Where is the justice, and there must be justice, for these long-term adversely impacted marine species? Now with the buying off of the public's and agencies' trust concerns with a popularist "mitigation" park, this deadly hot water will go on being dumped .into the ocean without ever the marine species getting just compensation survival mitigation, because the RWQCB says the project has for all time now been "mitigated". That is similar to what the SWRCB is condoning in the Draft Order when it passively states "If San Luis Obispo is unable to acquire the mitigation sites and obtain the required agency permits, it will consider alternative mitigation, including providing of monetary compensation funds to public or private agencies" (page 36). The SWRCB has acted irresponsible by forcing the City to hurry to complete and certify an obviously inadequate, EIR lacking any bonified mitigations. The SWRCB has pushed for this sloppy hurry up job on the ER in order for the SWRCB to rule on the City's request for an extension of its water rights Permit 5882. Was the SWRCB worried that someone would claim the City was not showing due diligence in putting the entire water supply of Salinas Reservoir to beneficial use? I do not know anyone who is arguing the City has not, as of late (in the 1990's to now), shown due diligence. But I know everyone who is making the claim the City has not shown due diligence, is instead making this rightful claim based on the City failing to show due diligence over the fust 48 years (1942 to 1990) of the Project. Therefore it is time the SWRCB act reponsibly as a reponsible agency under CEQA and, based on the above discussion, modify the Draft Order to indicate the SWRCB will not approve or disapprove the proposed Project until the City does a SEIR indicating where the mitigation sites will be for the many significant adverse environmental/ecological impacts upstream of the Salinas Dam. M Summary. In this written testimony on the SWRCB Draft Order WR 2000-_ of 8/24/00, I have given the administrative, legal, environmental, and ecological reasons .and justifications for requesting that the SWRCB: ( 1) for the reasons discussed in section "I. A." of these comments, modify its Draft Order (a) to void the City's existing Permit 5882 for the City failing to 15 show due diligence over a 58-year period to put the Salinas Reservoir entire water supply to beneficial use and (b) to, therefore, disapprove the proposed Project, and (c) to take no further action on the Project, unless the City chooses at a later date to apply for a new permit; (2), after it concluded in the Draft Order that the City's IIR was inadequate to determine if the Project would or would not have significant impacts on steelhead and their Salinas River ecosystem downstream of the Dam, modify its Draft Order to require that the City to do a Supplemental EIR on the Project for all the reasons discussed in section "I:B." of these comments, including fisheries and flow studies, and the need for these studies to be supervised and coordinated with NMFS and CDFG, and to proceed no further with the Project until the SIIR is done; (3), for the reasons discussed in section H. (under the headings "Second" and "Third") of these comments, modify its Draft Order (a) to require that the City do the ordered fisheries and flow studies under the close supervision of and coordination with the NMFS and CDFG, as the City has proven with its anti- steelhead biased IIR it cannot be trusted to do these studies independently, and (b) to require that the fisheries study not be done to find steelhead as a prerequisite to doing the flow study, but instead, due to the City releasing inadequate flows from the Dam for steelhead to likely exist in the 14.3 mile long Canyon reach of the Salinas River most of the time, that the fisheries study only be done to determine, as a prerequisite to doing the flow study, that if adequate flows are released from the Dam, if the Canyon reach of the Salinas River would be good habitat for the existence of steelhead there; (4), for the reasons discussed in section II. (under the heading "Fourth") of these comments, modify its Draft Order to provide the interim flow releases from Salinas Dam recommended by CSPA in our comments being provided to you on the Draft Order, to keep steelhead and other fish and aquatic species in good condition as required by Code Section 5937, until the necessary fisheries and flow studies are completed and the resultant derived flow regimes are determined and put into use, and (5) modify its Draft Order to require that the City to do a Supplemental IIR on the Project for all the reasons discussed in sections 'Ill." and "III." of these comments and to proceed no further with the Project until the SIIR is done, I again want to thank the SWRCB for this opportunity to comment on the SWRCB Draft Order WR 2000-_of 8/24/00.

John Moss,Utilities Director#, n Prepared By: Neil Havlik,Natural Resources Manager (),74, SUBJECT: APPROVAL OF PURCHASE OF REAL PROPERTY IN STENNER CANYON FROM UNION PACIFIC RAILROAD COMPANY CAO RECOMMENDATION 1. Approve the purchase of a 49-acre property in Stenner Canyon from the Union Pacific Railroad Company for$65,000,plus an allowance of$5,000 for closing costs. 2. To fund the purchase,bring forward and appropriate$70,000 from the Capital Improvement Plan's Salinas Reservoir Mitigation program(previously scheduled for 2002-03). DISCUSSION The Union Pacific Railroad (UPRR) property in Stenner Canyon consists of four parcels totaling 363 acres. One of the parcels, of 49 acres, lies within the San Luis Obispo Greenbelt, and is where the State Water pipeline and Salinas Reservoir pipeline emerge from the Cuesta tunnel. The parcel is a valuable resource area, offering significant potential.for oak woodland, wetland, and grassland mitigation. City staff has been very interested in this parcel for that mitigation potential, and for its value in cooperating with Cal Poly on long-term research on mitigation. Pursuant to Council direction, staff has had discussions regarding this property with the Railroad Company since August 1998. We have reached agreement on all matters of the transaction, and staff therefore recommends that the City Council approve the purchase. FISCAL EWPACT The cost of the land is $65,000, the appraised value of the property. There will also be minor closing costs, not to exceed $5,000. The property has considerable potential for oak woodland mitigation that will be needed in relation to either the Salinas or Nacimiento projects. Water Enterprise funding for the Salinas Reservoir Mitigation Program has been scheduled in fiscal year 2002-03 of the Capital Improvement Plan. It is recommended that these funds be brought forward and appropriated to support.this transaction. A portion of these funds will be returned to the Water Fund, since the City has also received a grant of$10,000 from the Federal Government in support of the acquisition. However, as is usual with Federal grants, the grant monies will be paid to the City only after the transaction has been fully completed with UPRR.

CA 95813-3000 Subject: On behalf of CASA and representing California Sportfishing Protection Alliance (CSPA) regarding fish and wildlife. following are my comments, evidence. and arguments opposing the SWRCB (the Board) proposed cancellation, in its March 34, 1999 letter (the Letter) to CSPA. of CSPA's formai/official Environmental Protest (the Protest) regarding Water Rights Permit 5883 (the Permit). Application 10216. of San Luis Obispo City (the City) relative to the Citv's 'proposal to divert even greater flows than it has since 1943 from the Salinas River at Salinas Reservoir by the Proposed Salinas Reservoir Expansion Project (the Proposed Project). Dear Mr. Scheuller: I am a professional fish and wildlife biologist. I received my B.S. in biology from Cal Poly University San Luis Obispo (Cal Polv) in 1969 and my NI.S. in fisheries from Humboldt State University in 1974. [ worked for California Department of Fish and Game (CDFG) in 1970 and the U.S. Fish and Wildlife Service (USFWS) from 1973-75 as a career fisheries biologist also doing substantial wildlife biology for the Service. I have been a biology technician in the Biology Department at Cal Poly since late 1975 where I have also taken considerable course work in wildlife biology. As an environmental advocate fish and wildlife biologist the past 34 years. I have worked and commented on many development projects at city, county. state, and federal levels. I have lived in SLO County for 38 years and the City for the last 10 years. The Proposed Project relative to the City's Permit 5S83 is the Proposed Salinas Reservoir Expansion Project and its Final Environmental Impact Report For The Proposed Salinas Reservoir Expansion Project (FEIR) certified illegally (due to its lack of a Mitigation Plan for biological and other impacts) by the City Council June 3, 1998. . I have testified orally and in writing on every phase of this project including public hearings on the Initial Draft Environmental Impact Report (IDEIR), in 1993-94, the Revised Draft EiR (RDEIR) in 1997• the Mitigation Advisory Committee (MAC) in 1996, the FEIR in 1998, and now the Board's ill-advised proposal to cancel CSPA's official Protest of the City's Permit 5383. According to the FEIR the proposed project would raise the height of the Reservoir about 19' and would increase the storage capacity from the existing 23.843 acre feet (AF) to 41.792 AF. an increase of about 75`,'c. This nearly doubling of the Reservoir size and diversion of sisnificant and cumulatively significant flows downstream (cumulatively significant in recognition of the historical diversion to fill the existing Reservoir to 23.843 AF combined with the proposed diversion of 17.949 AF to fill the expanded Reservoir to 41,792 AF) would only supply the City with about 1650 AF per year (AFY). My comments. evidence, and arguments opposing the SWRCB's proposed cancellation of CSPA's official Protest of the City's Water Rights Permit 5882 follow. 1. The Board's Letter of March 24 to CSPA is very inaccurate in its characterization that CSPA has not filed adequate environmental/ecological information or evidence to accompany its Protest demonstrating and documenting that the Proposed Project will cause adverse impacts downstream and upstream of the Salinas Reservoir Dam '(the Dam). This characterization of CSPA's Protest is inaccurate for two (2) significant reasons. First, over the past year. including this 45 day period the Board has given CSPA to provide such environmental documentation. I have received many documents from CSPA that it has filed with the Board supporting its Protest environmental damage/adverse impacts will result from the Proposed Project. I will not list those documents here because the Board has them and should be becoming familiar with them again. Apparently the Board had forgotten about them, else it is unlikely its letter of 3/24 would have been written proposing the cancellation of CSPA's official Protest. And secondly. the Board's letter is inaccurate and cause for great concern that a natural resource trust agency such as the SWRCA without adequate review of the entire EIR administrative record, which took place over nearly a 5 year period (1993-98). took the perspective of the City that the Proposed Project will not cause significant and cumulatively significant impacts to the environment. The Board took this position in its Letter mainly because it assumed that the City's act of certifying the FEIR demonstrated the Proposed Project is environmentally sound. However, jurisdictions as Cities vote all the time to certify EIRs that say with strong pro-project bias that the substantial evidence in the EIR demonstrates that significant and cumulatively significant adverse impacts will not occur because they have been mitigated to less than significant or cumulatively significant. Cities hire consultants to prepare EIRs and come to such conclusions-- else they will not be rehired by ANY developer entity. public or private, that is required by the California Environmental Quality Act (CEQA) to do an EIR. It is a disappointing fact that consultants are more concerned about being rehired than primarily protecting the environment under CEQA. Twenty-five years of promulgating CEQA in this State bears this out, and written history will eventually clearly record this sad environmental truth that is in immediate and serious need of societal. legal. and environmental correction! It is not surprising that even without a Mitigation Plan with specific mitigations. which has been proven illegal time and wain in California courts, the Cite certified the FEIR. They are under the illusion of desperation to acquire new water sources to continue wasting water_ as thev have in the pasts rather than learning bonified modern water conservation technology. .The City sees water acquisition at almost any and all environmental and economic cost as their duty to their citizens, rather than attempting to educate citizens to change their behavior to be more water conservation oriented. But what is surprising is that the Board that has an entirely different mandate than the City, took the City's perspective without question. Possibly more than any other agency in the State, the SWRCB has a public trust responsibility to ensure that the water's of the State are not used in a way that will harm those waters or the natural resources and people of the State reliant on them. Contrary to the City's EIR conclusion and the Board's erroneous conclusion in its Letter, there are scores of comment letters on the IDEIR. RDEIR. and FEIR, and scores more recorded public oral testimonials at hearings on the EIR and Proposed Project that strongly demonstrate that the project will have significant and cumulatively significant as of yet unmitigated impacts on the environment. As a citizen of this State. I ask that the SWRCB cease acting as an agent for the City, and instead act as the public trust agency we the public honor it as and seriously review these pri%ate, public, and aeencv comments that are ALL in the administrative record on this project. If the Board does this. I feel confident it will come to a different conclusion than it did in its Letter proposing to cancel CSPA's Environmental Protest on the inaccurate basis of the lack of evidence regarding environmental harm that would be caused by the Proposed Project. It is also important that the Board know that at the City's public hearing on its various proposed water projects on 3/33/99-- one day before SWRCB sent its Letter to CSPA proposing to cancel CSPA's Protest-- the City told the -1,1404- public there would be an upcoming Board hearing, possibly this summer, on CSPA's official Protest. This City hearing public information contradicts so dramatically with what the Board's Letter to CSPA says and attempts to do that I request that the City Staff Report, written public comments, and the entire City Clerk recorded 3/33/99 City public hearing for the City's proposed water projects he made a part of the SWRCB Administrative Record for its review of all information and evidence pertinent to its proposal to cancel CSPA's Protest. When the Board does this, it will find many public written and oral comments on many water conservation technologies the City inexplicably refuses to consider, which if it did, could make the City's Proposed Project to divert an additional 17,949 AFY of critical Salinas River flows for a mere 1,650 AFY supply yield a moot issue. Given this background. please hold to what the City told the public 3/33/99. and proceed with your plans all along to hold a Board hearing on CSPA's Protest. To assist your review of the many comment letters and oral testimonials on the Proposed Project and its EIR demonstrating and documenting that the Proposed Project would cause significant inadequately mitigated impacts on the environment. I have provided you with copies of all my Proposed Project EIR comment letters, although you already have access to them in the Proposed Project EIR Administrative Record. Niv comment letters in themselves document many aquatic and terrestrial Proposed Project impacts downstream and up!:rrcam of the Dam that would occur and have yet to be adequately addressed and mitigated, which will help you to come to the decision not to cancel CSPA's Protest. My comment letters herein attached as "Exhibit I" are (1) my 6/2/98 comment letter and attachments including color photographs on the FEIR. (2) my 8/13/97, 7/24/97 and attached photos, and 7/15/97 comment letters on the RDEIR, and (3) my 1/2/94 comment letter on the IDEIR. My 7/15/97 comment letter had 3 other attached comment letters from the City's Environmental Quality Task Force (EQTF), which I was a member of. I have not attached them here due to lack of adequate time to copy and attach them. But they and several other documents are listed as Comment Items 21B through 21J on page J-3 of Appendix J of the FEIR. And my 7/15/97 comment letter that they were originally attached to is listed on the same page as Comment Item 21A. All of these Comment Items are in Appendix J, and I request that you review them all in making your decision not to cancel CSPA's Protest. Finally, since your Letter proposing to cancel . CSPA's Protest refers to the City's Proposed Project EIR as the main documentation for cancelling the Protest, I now ask that you include the ENTIRE Administrative Record of all the Proposed Project EIR related hearings and EIR ( IDEIR. RDEIR. &: FEIR) documents as part of vour Administrative Record in the matter of your proposal to cancel CSPA's Protest. 2. The Proposed Project will have 2 major types of significant and cumulatively significant adverse impacts. It will have these impacts (1) downstream of the Dam on the Salinas River (the River) and (2) upstream of the Dam on the River and around the Reservoir shoreline. I will address major, significant. and cumulatively significant impacts downstream of the Dam in this comment section. My primary concern as a fish and wildlife biologist relative to the downstream adverse impacts of this project are in the approximately 14 mile long Salinas River Canyon (the Canyon) immediately downstream of the Dam. This is the area I believe the "Live Stream Agreement" (the Agreement) discussed in Appendix F has the least benefit for. One of many problems with the inadequate FEIR is that in appendix F it only gives the original sere sketchy wording of the Agreement. which is described in number "7." (new permit condition 8 for the City's Water Rights Permit 5882). The Agreement basically merely says that all downstream vested water rights will be presumed met by the Board if a visible flow exists, or if not. all water entering the Reservoir is to be released. I have heard word of mouth that there are various checkpoints on the River where a visible flow is looked for. However, the EIR failed to say where these checkpoints are or if they exist at all. In fact. the wav the Agreement reads, it could be interpreted that as long as a visible flow can be seen anywhere between the Dam and the River's confluence with Nacimiento River about 30 miles downstream. the Agreement is met. The public and everyone else involved have a right to know exactly what the Agreement is. This is extremely important for everyone's understanding of how the FEIR can conclude that there will he no sisnificant downstream impacts to the River and its reliant aquatic and terrestrial species because the Proposed Project does not alter the Agreement. But no more than the FEIR tells us about the Agreement, it must be assumed that if a visible flow is seen somewhere in the above described River stretch. the Agreement is being met. and that does not support a conclusion the Live Stream Agreement prevents adverse impacts to the River Downstream of the Dam-- with or without the Proposed Project. One problem is that the further downstream one goes on the River in this stretch. the more likely they are to see a visible flow as more and more streams enter the River from a larger and larger watershed. This makes the likelyhood that a visible flow will be seen further downstream in the Atascadero and Paso Robles cities stretch of the River very likely. On the other hand. in the 14 mile Canyon just below the dam where only 3 streams enter the River and .the watershed is only a few square miles. a visible Flow may not exist at all. And as far as vested downstream water rights referred to in the Agreement are concerned. unfortunately little of the concern to date has been in the Canyon stretch of the River. Almost all of the concern so far has been along the valley stretch of the River where private property owners abound and where the mentioned cities and towns of Templetown and Santa Margarita exist. Almost all of these entities draw some portion of their water from River basin wells and pumps addressed by the Agreement. Even CDFG does not seem to be very interested in the 14 mile Canyon stretch of the River. This is demonstrated by the fact that their comment letters on the EIR do not address adverse impacts that would occur to the River ecosystem downstream of the Dam due to the diversion of even more water from the River than the City has historically diverted! Soy many people and water entities in towns and rural areas in the valleys downstream of the Canyon are watching to be sure visible flow exists in the River along these fairly heavily populated areas. But who is watching to ensure a visible flow exists throughout the Canyon. or that a flow exists at all in the Canyon. even though visible flow exists further downstream in the populated valley areas'? My concern about this was greatly elevated on April 23 of this year when I was invited onto .\Ir. Otto Schmidt's Canyon property along the River several miles downstream of the Dam. There, was virtually no flowing water in the River in the Canyon! Photographs I and 2 of my attached "Exhibit 2" (Photographs) shows this situation at the private instream earthen dam immediately upstream of Mr. Schmidt's property. I estimated there was less than I cubic feet per second (cfs) flow coming over the spillway to the private dam. The lack of flow was not due to the private dam holding back water. since the reservoir behind the dam was at maximum capacity and the spillway was releasing all of what little water was flowing in the River. Also. I checked various riffles on Mr. Schmidt's property and they all were flowing at less than I cfs. Last year when I was at this site over a month later in the year. May 30. 1998. there was significantly more flow in the River coming over this same spillway. as shown by photographs I and 2 in my attached 6/3/98 FEIR comment letter. I did not estimate the flow last year. but now looking at the photograph. I estimate that it was likely around 10 cfs or more. I recognize last year was an EI Nino year with late and above average rainfall, but this year had enough late .rain to bring it up to a nearly average rain year (around 30"). Furthermore, one week earlier on April 17 of this year. I was on the River just upstream of where it enters the Salinas Reservoir and the flow entering the Reservoir was substantial. I did not estimate it at the time, but my recollection of the flow conditions was it was likely somewhere around 15cfs. So I have grave concerns about flows in the Canyon relative to the FEIR saying there would be no significant impact below the Dam from the. Proposed Project due to the Live Stream Agreement not being changed by the Proposed Project. Whereas in reality the "Live Stream Agreement" seems to be killing the flows in the Canyon. as on 4/33/99. So, as previously discussed herein, there may be visible flows down in the valley where a very large watershed and many steams feed into the River. But up in the Canyon. where the Dam blocks the Canyon off from about 130 square miles of upstream watershed and all of its flows that the Canyon would otherwise benefit from, there is a very small. narrow watershed obviously incapable of supplying the River with anything more than a trickle or less during a nearly average rain year, as I observed on 4/33/99 and as can be seen in Photo I. I recognize that during those more rare drought periods when no flow is seen downstream, the second part of the Agreement comes into play requiring then that all of the River flow coming into the Reservoir must be released from it. And under these less common conditions, the River stretch in the Canyon would benefit first from any releases, since it is closer to the Dam than the downstream urbanized valley areas are. But this is somewhat of a paper tiger, since under these types of drought conditions, no River flow may be entering the Reservoir either-- so therefore none has to be released! From this evidence. either during drought or wet periods. I conclude that it is very likely the Live Stream Agreement is inadequate to supply the 14 mile Canyon stretch %with enough flows to maintain an adequate aquatic ecosystem including threatened steelhead. The question that I now ask and that must be answered is where are the instream flow studies done by the City and/or CDFG proving and justifying that the Live Stream agreement is based on sound scientific study and evidence'? When was a standard Instream Flow Incremental Method study done by the City or CDFG (1 ) in the Canyon and (3) elsewhere on the River demonstrating that the Live Stream Agreement actually protects aquatic species and their Salinas River and riparian habitat, as native fish and amphibians including Federally threatened steelhead and red-legged frogs, etc.'? And when were such studies done to prove that the Agreement adequately protects the River habitat for many terrestrial species reliant on the River system and its riparian zone. including federally threatened willow flycatchers, least Bell's vireos, and arroyo southwestern toads, whose ranges historically and may still include the Salinas River downstream and upstream of the Dam'? .and whose recovery habitats certainly should include the Salinas River downstream and upstream of the Dam. Or when vas an even simpler flow study methodology as the "Montana Method" (attached as "Exhibit ?") done on the Salinas River, as it has been done for other rivers with dams. to help demonstrate that the Agreement is scientifically aquatically adequate to maintain native aquatic species in good condition'.) Until such fisheries instream flow studies are done on the River in the Canyon and downstream of it. the agreement, which may have just been an unscientific political deal. could be far more environmentally damaging than beneficial. If the Agreement is simply based on the conclusion some water in the River is better than no water, but it is not known whether or not the Agreement "flows" .are adequate to sustain aquatic and terrestrial species reliant on the flows, then it is a very damaging Agreement. Bad "mitigation" perpetuated without proof or evidence as to its effectiveness for accomplishing what it is intended is compoundingly bad. Such ineffective but unquestioned and untested mitigations tend to get used again and again elsewhere, with similar long term adverse environmental results occurrg there also. This Live Stream Agreement is especially environmentally suspect because the City, its consultants, and the EIR all rest their conclusions the Proposed Project will not have a significant adverse environmental impact downstream of the Dam needing flow mitigations because the Live Stream Agreement is . not being changed by the Proposed Project. But if the existing Agreement is not adequate for the River ecosystem. then it can only be concluded that diverting even more flows from the River by the Proposed Project will compound the inadequacy of the Agreement. The Board needs to require that the City and/or CDFG either provide the scientific evidence of these already done stream flow studies proving the Agreement is adequate to protect the River ecosystem including threatened species as steelhead and red-legged frogs and their recovery habitat. or the Board needs to require that these studies be done. And because a Live Stream Agreement is being perpetuated on the possible myth that it is adequate when in reality it may not be. the Board needs to require such flow study evidence before it takes any further action on the City's Water Rights Permit 5882. Furthermore these flow studies are necessary because Fish and Game code 5937 requires that adequate flows be maintained in streams to keep all fish and their habitat ix" good condition. It is unknown but unlikely that the Live Stream Agreement is in compliance with this code section. Flow studies must be done to ensure this code section is being complied with. or that it will soon be complied with if it currently is not being complied with. Furthermore, since it is known and uncontested that the Citv's existing and historical diversions of Salinas River flows have significantly adversely impacted native fishes including threatened steelhead (see appendix L. section Appendix L-2. page L-1-+), the Board shou;d take the position that the City has a responsibility to mitigate past impacts to the River. The Board needs to ensure that the City acknowledges that diverting even more water from the River would have cumulatively significant adverse impacts on the River when combined with its existing and historical diversions that are cumulatively in need of flow mitigations. The Board then needs to ensure that the City adequately mitigates these impacts through doing* instrcam flow studies and O . using appropriate and adequate mitigations derived from such instream flow studies. It is irresponsible that the City has attempted historically with its original Salinas Reservoir River diversion project and now again attempts with its Proposed Project to deny major, significant, and cumulatively significant adverse impacts on the downstream River ecosystem, including steelhead and their habitat, that need more and adequate flow mitigations. They have acted in this unacceptable manner despite the fact that CEQA requires a cumulative projects impacts analysis, including past, present, and proposed future projects, that in turn requires appropriate mitigations. With this CEQA background relative to the City's flow diversion adverse impacts on the Salinas River including on steelhead and their habitat, the Board needs to require these instream flow studies of the City directed at the application of appropriate flow mitigations for steelhead, other aquatic and terrestrial species, and their River/riparian habitat. And it is because the City is so tenuously clinging to the conclusion there will be no significant or cumulatively significant adverse impacts downstream of the Dam resulting from the Proposed-Project that need new flow mitigations. the Board needs to vigorously retain CSPA's Protest. In fact, the Board has strong support from the FEIR itself that the Proposed Project will cause cumulatively significant downstream impacts. Page 5-2 states "the cumulative effects of the project when considered together with the overall surface water diversions and groundwater withdrawals by all downstream users could be considered a significant environmental impact". Furthermore. relative to downstream impacts. page 3.4-20 states "the greatest impacts are expected to occur during periods of reservoir refilling following extended drought periods". The City is willing to admit to such impacts, but then hedges on any mitigations on several bogus grounds. On page 5-2 it indicates it is willing to participate in a basin-wide water management plan. A willingness to participate in a basin-wide water management plan is not flow mitigation for the City's past. present. and Proposed Project flow diversions from the River. It also argues Proposed Project flow reductions would occur during wet winter months when there would be adequate flow in the River despite what the City diverts now and would additionally divert with the Proposed Project. This may be true many miles downstream where there is a large watershed and many streams draining into the River to greayty dilute the environmental effects of the City's water diversions. But it is not true in the 14-mile Canyon where there is only a very narrow, steep, small watershed where winter flows flash in quickly and flush out and disappear just as quickly-- in a matter of hours, or a few days at most. In fact, other than during uncommon Dam spill years (only once every 3 years on average over the past 50 years-- see Appendix K-E and Appendix L-2 of the FEIR) the City has done no hydrology in the EIR to prove there will be adequate, sustained flows in the Canyon when it is diverting all of the flows with its Proposed Project. And finally, the City defaults to its main argument, the Proposed Project will not cause adverse impacts in need of flow mitigations because it is not altering the Live Stream Agreement, which I have argued here is environmentally suspect and potentially in the long term even damaging to the River ecosystem. However, because the FEIR admits to cumulatively significant downstream adverse impacts from the Proposed Project and then weasel words around having to do any flow mitigations to offset the impacts, the Board has strong grounds to require the necessary instream flow studies and associated flow mitigations ensuing from such studies. Regarding the downstream impacts of the Proposed Project, there are several other points I will now cover. This is necessary because the City with its Proposed Project EIR has went to considerable effort to demonstrate that the Salinas River including the River stretch in the Canyon is not steelhead habitat worthy of acknowledging for mitigation, restoration, and recovery for steelhead. However, if one carefully reads the 2 parts to Appendix L of the FEIR, entirely different conclusions can be arrived at than the River is not good steelhead habitat and the Proposed Project would do nothing to worsen that condition to threatened steelhead that in turn would require Proposed Project flow mitigations. The first part of Appendix L is Appendix L-1, which is titled "Additional Information on the Occurrence of Steelhead .along the Salinas River Below the Dam". When one reads the 6-page Appendix L-1, a logical conclusion that can be reached after this fairly brief historical review of steelhead in the Salinas River dating from the early 1900's to the present, is that the Salinas was once very good steelhead habitat destroyed in large part by the building of the Salinas Dam in 1942. Snyder (1913) reported that "large numbers" of steelhead entered the Salinas River. By 1965 CDFG estimated the steelhead spawning runs to be a little more than 500 fish. Though there is no numbers given by Snyder in 1913, it can be assumed that his reference to large numbers of steelhead entering the River. meant numbers much larger than 500 spawning steelhead. By 1991 Nehlsen et. al. reported the Salinas River steelhead was at moderate risk of extinction. However, in appendix L-1 no information was given on the estimated numbers of spawning steelhead in the River in 1991 when Nehlsen made his extinction risk analysis. So it is not known if steelhead numbers are above or below the 19$0's estimate of 500 fish. 6 Three conclusions can be made from this information. First. the River was once very good steelhead habitat, second, construction of the Dam in 1942 dramatically adversely impacted the steelhead habitat to reduce steelhead runs to 500 fish by the 1910's, and third, whether Salinas River steelhead spawning numbers are now above or below 500 fish, as of 1991, the fish is at risk of extinction. Contrary to what the City irresponsibly concludes in the EIR. I can only come to one conclusion from this information-- it is time to restore flows to Salinas River below the dam to not only remove the risk of extinction to steelhead but to also help the steelhead recover to numbers well above 500 fish per year. These flows need to be adequate enough to ensure in most years the Salinas - River can be migrated up by spawning steelhead from the ocean to the Dam. At l0 the Dam spawning steelhead could be trucked to their historical headwaters above the Dam. or a fish ladder could be built around the Dam. As for Appendix L-1 presenting some information derived from minimal City consultant site trips in 1997 that some of the Canyon stretch of River may not be adequate steelhead spawning and rearing habitat. I presented written and photographic evidence in my 7/24/97 comment letter on the RDEIR and my 6/2/98 comment letter on the FEIR contradicting this EIR conclusion. I will not cover all of that information again, but please read my 2 comment letters and look at their supporting photograph evidence. I will, however. briefly cover the issues that the EIR/Appendix L-I concluded River water temperature and man-made barriers are limiting factors in the Canyon precluding this stretch of River from being high-quality steelhead spawning and rearing habitat. I provided River temperature information in my 7/24/97 and 6/2/98 comment letters demonstrating water temperatures are not a problem to spawning and rearing juvenile steelhead in the Canyon stretch of the River. I also provided written and photographic evidence in my 6/2/98 comment letter that the upper private dam in the Canyon would not be a migration barrier to either upstream spawning steelhead or downstream migrant juvenile steelhead. However. I did not have site visit or photographic evidence 6/2/98 on the lower private dam. On 4/10/99 I obtained this evidence and have concluded that except under very low flow conditions of only a few cubic feet per second, it would not be a barrier to upstream migrating spawning steelhead. This private dam and its spillway can be seen in photographs 3 and 4 of "Exhibit 2". The spillway has a jump about 6 feet high, which with adequate Flows is well within adult steelhead leaping ability. But I do not believe they could have leaped over the spillway with the flows of 4/10/99 shown in the photographs. I estimate that there was only about 5 cfs flow in the spillway 4/10/99, and I also estimate it would likely take about twice that amount of flow in the spillway before steelhead could leap over the spillway. In fact there is adequate evidence that spawning steelhead are getting over this lower barrier in the Canyon. Appendix L=l discusses the 24" steelhead that was caught in the pool just below the upper private dam in the Canyon, so obviously it jumped over the lower dam spillway. I have had a recent discussion with Chuck Marshall of CDFG who saw this frozen steelhead and Mr. Marshall verified to me it was a steelhead and not a hatchery fish that could have washed over the Salinas Reservoir Dam. Also Mr. Schmidt said that when CDFG. City employees. and others saw this large steelhead in 1997, tissue samples were taken for genetical testing. The Board needs to now request the results of these genetical tests on this steelhead because at the City's FEIR certification hearing 6/2/98, the City's Utility Department Director attempted to discredit what the property owner said regarding the steelhead was caught on his property. The Utility Department Director alleged that the steelhead could have been caught somewhere else and then presented as a steelhead caught where it was said to have been caueht. This accusation that the property owner was not telling the truth could be dispelled by the results of the genetical testing that was going to be done on this steelhead's tissue samples. I request that the Board follow up on this issue. Furthermore, Mr. Otto Schmidt, who owns the River property just below the upper private dam in the Canyon, is sending you in this 45 day period (for supplying evidence supporting not cancelling CSPA's Protest). a photograph of an approximately 20" steelhead he caught spring of 1997 in the River on his property. He is also supplying you with written evidence that he caught juvenile salmonids at about the same time he caught the large one in the photograph. He said these were fairly small. (6" or so), sleek. well conditioned, silvery fish, with all their fins intact, in contrast to the larger. fin-clipped, stocked trout he occassionally catches that wash over the Salinas Dam from time to time. Based on this discussion with Mr. Otto, I too conclude the smaller salmonids he has caught were juvenile steelhead. He also told me that in the 70's and 80's there were fairly large runs of upstream migrant spawning pacific lampreys in the River. He has not seen lamprey in the River since the 80's. However. I have talked to several people recently who have seen or heard others describe seeing lamprey in the River near Atascadero in the past 5 years. Except for the lamprey information, which was presented here for recent native lamprey documentation in the River, all of this information leads to a logical conclusion the stretch of River in the Canyon is steelhead habitat. However, the key to the question how good of steelhead habitat it is or could be. rests with the City's willingness or lack of willingness to provide adequate flows i-n the Canyon below the Dam during the winter steelhead migration season and the summer juvenile steelhead rearing season. Adequate flows are necessary so the 2 private dam spillways can be negotiated by upstream spawning steelhead and so gravels in the ample gravel spawning and rearing beds of riffles and runs (ample as attested to in Appendix L-2 and my EIR comment letter of 7/24/97) will be adequately cleaned. This cleaning of gravels by adequate flows is critical for steelhead so (1) the steelhead eggs will not be suffocated by silt and (2) the gravel bottom will provide good clean bottom substrate for a diversity of aquatic insects and other aquatic invertebrates, which the juvenile steelhead will feed on while rearing in these gravel bed areas. However, despite what the City says in its Proposed Project EIR. for the past 50 years adequate natural flows do not exist in the River below the Dam in the 14 mile long Canyon and the City has not provided adequate winter and summer flows from the Dam outlet for steelhead, and often it has provided no flows for steelhead. It is time it provides these flows voluntarily or is forced to do so by the .Board and other State and Federal trust agencies. This leads into my discussion of the second part of Appendix L. which is Appendix L-2 titled "Additional Information on Biological Consequences of reduced spills". This Appendix only deals with a hydrological model analysis of winter flows in the river during uncommon spill years. which has been 17 Dam spill years out of the total 50 years the City has historically diverted water from the River. This indicates that on average there is only Dam spills once every three years. So the study did not hydrologically analyse flows in the _ Canyon for 33 of the 50 years. 66% of the years. !Z But even for the spill years Appendix L-2 did analyse, it came to an untenable conclusion that the Proposed Project will not adversely impact the River's ability to scour the River bed in the Canyon. This scouring is important to (1) sustain the long term dynamic cycle of riparian vegetation regeneration, (2) create fish and other aquatic species habitat (as pools, riffles, cut banks. etc.), and (3) cleanse gravel beds and sand bars for spawning fish, their hatching eggs, and aquatic bottom invertebrates which form the base of the aquatic food web of life. This conclusion in Appendix L-2 is untenable because what the model predicts is not what is actually happening to the River most of the time due to the City's past and present diversions, which would only be worsened by the Proposed Project. It could be true that in these spill years, which only happen 33% of all years. these scouring functions of. the River in the Canyon are attained. But even for these years, no one knows if the model is correctly predicting these scour functions of the River, because no one is looking at the River itself during these spill years to see if these scouring functions are actually occuring. Actual field studies need to be done to prove if the model is accurate or not. Furthermore, in those 66% of the years when the City is diverting all the upstream watershed Flows, it is doing major and significant hydrologic damage to the River, including eliminating critical scour function. The City argues in the EIR it is diverting these flows mostly in the winter when there will be adequate scouring flows in the River in the Canyon stretch. However. despite this EIR argument, other than during infrequent spill year modeling, the City has persistently refused to do hydrologic flow analysis in the Canyon to prove there will be adequate flows for scouring, spawning, egg hatching, rearing, bottom invertebrate biodiversity, etc. And despite the City's EIR argument that the Proposed Project will not have significant adverse flow impacts, due to mostly diverting during wet winter months and the Live Stream Agreement, currently adverse flow impacts are occuring and will only be worsened by the Proposed Project. For example, when I was on Mr. Schmidt's River property in the Canyon on :/23/99, clean gravel beds I had seen and photographed in 1998 (see Photo 5 of my 6/2/98 FEIR comment letters showing clear flows and clean gravel interspersed with rocks in a run at the tail of a long riffle just out of view upstream) were covered with silt. This was due to the lack of flows to scour the gravel beds clean. Apparently what is happening at least some of the time during the 66% of the years there are no Dam spills, is contrary to what the EIR argues, there are not enough flows generated in the small, narrow Canyon watershed to provide sustained flows high and fast enough to adequately clean the gravel beds. It may be true that during short periods of hours or days at most. silt transporting higher flows occur. But apparently these silt transporting flows stop just as fast as they start and the silt they were transporting is then deposited in place on gravel beds and sand bars, with significant adverse impacts on the River ecosystem including steelhead. It has been my experience with coastal streams as the Salinas River. that although sudden high flows, that are also over with rather suddenly, may 13. provide the scouring functions for regenerating riparian vegetation and creating fish and other aquatic species pool, riffle. bank, etc.. habitat, such temporary flows do not properly scour the gravel and sand beds clean of silt. This takes longer more sustained flows that need not be of the high magnitude of the flows needed for the other stream scouring functions. Based on what I saw 4/23/99 on Mr. Schmidt's property, neither of the City's EIR promoted arguments that (1) winter flows below the Dam will provide enough scouring to offset City diversions from the River and (2) the Live Stream Agreement will maintain the downstream River in adequate ecological condition, are working to prevent significant adverse impacts to the River. Flows generated in just the small watershed of the Canyon are not adequately scouring gravel and sand bars clean and the Live Stream Agreement is not providing adequate, if any, flows to the Canyon stretch of the River. And this damage to the River in the Canyon due to lack of flows is occurring even when substantial flows are in the River above Salinas R rvoj r , as was the case on 4/17/99. My belief is that although there has been no significant rain for a month now. the flow in the Salinas River above the Reservoir is still fairly substantial-- scouring the bottom clean and supporting cold water fish and other aquatic life upstream of the Reservoir. unlike what is happening downstream of the Reservoir. I will soon verify this belief with another site visit upstream of the Reservoir. So the Board needs to not be mislead by the EIR claims winter flows below the dam and the Live Stream Agreement are adequate to maintain the ecological health of the River ecosystem, when my experience indicates neither are adequate. Instream fisheries flow studies in the River below the Dam, especially in the Canyon, are necessary without further delay. As part of these instream flow studies, the Board also needs to require that the City provide it and the public and all other concerned parties as CSPA. CASA. and the Santa Barbara Environmental Defense Center (EDC). with all flow release data from the Salinas Dam in cubic feet per second (not AFY which has little application to stream surface flow studies and can be very misleading information). This flow release data needs to be in the smallest increments of time that the City has. as on a daily or hourly basis. And this flow release information in cfs needs to go back as far as the City has records for including as far back as the inception of the Live Stream Agreement and preferably all the way back to the City's involvement with the first operation of the Dam in the early 1940's. And this flow release information needs to make it clear what flows in cfs are (1) from spills. ('_) from the Dam outlet release valves, and (3) for meeting the Live Stream Agreement. Finally, on the issue of the Proposed Project's impacts in the Canyon downstream of the Dam, the City has used its EIR hydrologic data to very questionably demonstrate lower flow reductions than would actually occur. I have addressed this in my previous EIR comment letters, which I have requested that you read, but I will summarize this problem here. Several places in the EIR it is indicated flows just below the Dam will be decreased about 6.79c by the Proposed Project (Table 3.4-13). However, on page ES-6 of the EIR it is indicated that this Proposed Project flow reduction at the downstream base of the Dam is 13.717c (see page 8 of my 6/2/98 comment letter for the simple — calculation vieldine 13.75'0). And in the Bob Roos "Salinas Reservoir Expansion Downstream Flow Impacts" report (attached here as "Exhibit 4") filed in local libraries, different methods of calculating the Proposed Project flow reductions at the base of the Dam (Dam Outlet) yield flow reductions of 6.45% (a DEIR figure changed to the above referred to 6.7% in the FEIR), 11.2%, 13.1%. 15.3%, 29%. 30%. 32%, and 58%. Obviously by purposely selecting the method that gave the smallest flow reduction to present in the EIR, the City is using statistics to bend the facts to present its case in the best light. But it matters little whether one takes the smallest 6.7% number used by the City in the FEIR. or the 13.7% number which I quickly determined from page ES-6 of the FEIR (which contradicts the 6.7% figure), or any other number. What does matter greatly is that when that number is added to the approximately 40% number the City now diverts from the River annually, the cumulative impacts of the original and Proposed Project diversions are about 50% or more of the entire flows in the River! The City has gotten away without providing adequate flow mitigation for these past and current flow diversions. And now with the Proposed Project it is trying to divert even more flow without any .downstream flow mitigation to the River ecosystem in the Canyon or further downstream. It is clearly time that the Board require this flow mitigation. To this end it is only environmentally just, fair. and legal that the Board retain CSPA's official Protest. This will help to ensure that the City mitigates its Salinas River water diversions appropriately and adequately for steelhead and all other species and habitats in the Salinas River ecosystem downstream of the Dam. 3. I will now address major, significant, and cumulatively significant impacts of the Proposed Project upstream of the Dam. It is important that the Board read my previous comment letters, especially those of 7/24/97 on the RDEIR and 6/2/98 on the FEIR. as they go into considerable detail on what the unmitigated or inadequately mitigated adverse impacts of the Proposed Project would be around and upstream of the Salinas Reservoir. I'm not going to repeat that critical and important information here, when you already have it. But I do want to emphasize and summarize what I consider to be the most important impact above the Dam. This would be the loss of what is without question one of the most magnificent and extensive willow riparian forests left in the State. Most others have been destroyed by all sorts of development including inundation drowning by over 160 large manmade reservoirs. And much of the riparian forest I am concerned about with this Proposed Project disappeared from inundation drowning by the construction and filling of the original Salinas Reservoir 50 years ago. It is preposterous that the FEIR argues that if the Proposed Project is built and the Reservoir level is raised 19', this magnificent riparain forest about 2 miles long on the Salinas River will notbe entirely destroyed by inundation. No trees beyond seedlings and saplings would ever reestablish were this riparian forest now exists. .and these seedlings and saplings, if they grow at all, would only survive until the next high water inundation drowns them a year or two - later. Such small intermittent "twigs" would never replace the multi-storied willow riparian forest canopy that . currently exists nearly undisturbed by human intervention-- especially since cattle grazing has been eliminated in the riparian area in recent years by the Corps of Engineers/SLO County. Still the City argues in its EIR that some of this riparian forest will survive the frequent and long inundation periods. To disspell this argument once and for all, please see Photograph 5 in "Exhibit 2", which I took on .4/17/99. This Photo shows the current high water line at the upper end of the Reservoir where the River enters the Reservoir. Note the downstream end of the River riparian forest, which is about a quarter mile wide at this point. The line where the high water line of the Reservoir intersects the riparian forest is dramatic and telling. On the upland side of the Reservoir high water line stands a magnificent and ancient riparian forest to 50' or more high. On the lake side of the Reservoir high water line not a single tree exists! There are some native and some weedy perennial and annual herbaceous marsh plants (palustrial wetland hydrophytes), but no riparian trees or shrubs exist. If the Reservoir is raised 19' by the Proposed Project, it will reach about 2 miles upriver and between there where it establishes its new high water mark and the existing high water mark. every single tree (tens of thousands of them) in this riparian forest will be destroyed by inundation drowning-- just as was the entire riparian forest 50 years ago that once existed below the level of the existing Reservoir high water mark. Furthermore, another 3/4 mile of excellent riparian forest will be destroyed by drowning on Alamo Creek with large old willows that in some places reach to 60' or more in height (see Photo 6 of "Exhibit 2"). And over a quarter mile of riparian forest combined will be lost on Toro, Chaparral, and Salsipuedes creeks. Color Photographs 6 through 14 of my attached 6/2/93 FEIR comment letter show portions of the 2-mile long Salinas River riparian forest that would be destroyed by inundation drowning including some of the 2470 oaks that would also be destroyed. The FEIR says that though it has not yet done so, the City will find places to mitigate the loss of this magnificent, intact Salinas River riparian forest. Despite boasts the City makes that it can mitigate this riparian forest loss, the best it will ever do is restore bits and pieces of riparian forest in various other places to attempt to offset the over 70 acres of riparian forest/wetland that would be destroyed by the Proposed project. But these will be smaller fragmented riparian areas compared to the large intact forest that will be destroved. And the former would never replace or have nearly the ecological value to wildlife as the latter. Therefore, such proposed riparian restoration mitigations of various un-named areas, likely many far from the area of proposed impact, are inadequate for replacing the existing large, complex. diverse, riparian forest. Since I wrote my 6/2/91 comment letter on the FEIR. I have talked several times by phone with Mr. Roger Zachary who is a long-time biology teacher at Atascadero High School. Mr. Zachary has provided me with new information that needs to be considered for the Proposed Project. In March 1997 Mr. Zachary discovered foothill yellow-legged frogs in small wetland drainages along the trail on the north side of the 2-mile long Salinas River riparian forest I just discussed, and that would be destroyed�by inundation by the Proposed Project. These frogs. which are currently on both the Federal and l�. State species of special concern lists, were found within 100' or so of Toro Creek near its confluence with the River. The problem is this entire area where Mr. Zachary found the frog and its habitat would be destroyed by inundation from the Proposed Project. For the Board's information and review I have attached Mr. Zachary's brief report here as "Exhibit 5". Furthermore, he is having 3 color photos prepared from slides and these will be available this weekend. I will send you color copies as soon as Mr. Zachary supplies them to me late this weekend or ear'.y next week. The destruction of this rare frog's habitat by the Proposed Project needs to be taken into consideration as part of the Board's review of the City's Permit 5882. It is therefore important that the Board preserve CSPA's Protest so this and other environmefial/ecological information can be properly dealt with at CSPA's rightful Protest hearing. Finally, regarding impacts of the Proposed Project upstream of the Dam. I will now briefly discuss the approximately 2170 oaks (live oaks, valley oaks, and blue oaks) and 469 gray pines according to the FEIR that would also be destroyed by inundation from the Proposed Project. It is easy to talk about the destruction of trees. but it is more difficult to understand the loss without visual perspective. The Board and the SWRCB staff should go to Salinas Reservoir and see for yourselves the tremendous magnitude of the potential loss of these ancient and large oak and pine trees around the Reservoir in the Proposed Project inundation zone. This is especially important because unfortunately the EIR does not provide color (or any) photographs of these trees that would be drowned. However, for the time being, to assist you in your current review to come to the conclusion to retain CSPA's Protest. I have provided you with Photographs 7 and 8 (taken 4/10/99) in "Exhibit 2" here. These photos show just a small portion of the oaks and pines that would be drowned by the Proposed Project. but some visual perception of this magnitude of native tree loss is better than none provided by the EIR. The FEIR says it will mitigate the loss of these mostly ancient and large oaks and pines. But due to their age and size and the fact that the City will likely later inappropriately propose planting seedlings and saplings in rapidly disappearing valley grassland habitat, no adequate mitigation exists to date for this great amount of native tree habitat loss. The Board needs to consider this native oak and pine tree loss that would occur from the Proposed Project. And in this respect the Board needs to preserve CSPA's Protest so this and all other environmental/ecological information and evidence relative to the Proposed Project can be properly dealt with at CSPA's official Protest hearing. In summary, CSPA. others, myself, and the EIR provide enormous information. evidence, and arguments on the major, significant, and cumulatively significant unaddressed. inadequately addressed, or inadequately mitigated adverse impacts of the Proposed Project. And these inadequately mitigated adverse impacts would occur extensively upstream and downstream of the Dam. as discussed herein and in many other people's and agencies documented oral and written comments on the Proposed Project and its EIR. So, please take all this information as to the adverse environmental/ecological impacts of the Proposed Project into consideration. and when you do. I am confident that you will come to the correct conclusion to preserve CSPA's Environmental Protest so it can properly be addressed at a Board hearing. Sincerely, �j RECEIVED NOV - 9 2000 t Mr. Harry S. Schueller, Chief Phil Ashley SLO CITY CLERIC Division of Water Rights California Sportfishing State Water Resources Control Board Protectin Alliance (CSPA) P. O. Box 2000 1586 La Cita Court Sacramento, CA 95812-2000 San Luis Obispo, CA 93401 805-544-9741 (home) 805-756-2505 (work) September 29, 1999 Subject: Following is my written testimony as a fish and wildlife biologist for CSPA regarding its Protest against San Luis Obispo City's water diversion Permit 5882 (Permit), Application 10216, for its Proposed Salinas Reservoir Expansion Project (Project) to be heard by the State Water Resources Control Board (SWRCB) at its hearing in Sacramento on October 12, 1999. I. Background: I have provided comment letters and oral testimony on the Subject Project including the Initial Draft Environmental Impact Report (IDEIR), the Revised Draft EIR (RDEIR), and the Final EIR (FEIR). This testimony as well as other oral testimony at Project meetings and hearings is published in the FEIR, except for my oral testimony and comment letter on the FEIR, which I provided to San Luis Obispo City (City) at its hearing on the FEIR 6/2/99. My oral testimony on the FEIR is part of the transcripts of the 6/2/99 hearing. My comment letter on the FEIR was supplied to you as part of Exhibit 1 in my letter to you May 5, 1999, justifying the prevention of the dismissal of CSPA's Subject Protest, and therefore my 5/5/99 letter and its 5 Exhibits are part of the administrative record for the Subject hearing on October 12, 1999. However, because my 6/2/98 FEIR comment letter is directly tied to some of my written testimony herein, it is also being provided to you as CSPA "Exhibit FF" for the Oct. 12 SWRCB hearing. IT. An Unfriendv SWRCB Hearing Arrangements For The Working Public: The SWRCB has scheduled the Subject hearing for 10/12/99, despite efforts by CSPA Counsel to have that date postponed for several reasons. However, another reason this date is inappropriate is it has been established in conjunction with another SWRCB hearing on November 1, 1999, for the same City's Proposed Water Reuse Project (WRP) diversion from San Luis Obispo Creek (SWRCB Application WW-2). It is impossible for CSPA and its representitives including myself to provide adequate testimony on the Subject Project and the WRP based on these conflicting hearing dates. The SWRCB has provided myself and CSPA with a letter dated September 17, 1999, stating for the WRP "The State Water Resources Control Board has tentatively scheduled a hearing on this matter for November 1, 1999. This matter will be continued on November 2, if necessary. Formal notice of the exact time and place of the hearing will be given at least 20 days prior to that time." But 20 days prior to Nov. 1 is October 12-- the exact day the SWRCB Subject Project hearing starts in Sacramento! And since it is now less than two weeks until the Subject hearing on complex issues, CSPA's limited representatives and their also limited time and monetary resources are currently devoted to the Subject hearing. The SWRCB Sep. 17 letter then states "The notice will contain a list of the hearing issues and procedures for participating in the hearing." But as the SWRCB letter attests to, the SWRCB allows very little time after the notice for noticees to prepare often considerable and complex written hearing testimony and supporting evidence/documentation. How can CSPA including myself be expected to be preparing and sending you our testimony for the WRP at the same time we are either in the last few days of preparing for the your Subject hearing or we are actually in Sacramento providing oral testimony on the Subject Project? This type of hearing arrangement is publicly unfriendly because members of the public like myself who have full time jobs other than the kinds that get paid for working weekday business hours for their SWRCB work and testimony, have to prepare all of our input and testimony at nights and on weekends when we have many other family and social obligations. However, since the same SWRCB staff person is a lead person on both the above discussed projects, it should be relatively easy for the referenced staff member to immediately coordinate with you to correct this hearing date conflict. In this regard I would appreciate it if you would reschedule the SWRCB hearing on the WRP after Monday, November 8, 1999: After the Oct. 12-13 Subject hearing, I must devote all of my spare time outside of my 40-hour work week to working extensively with my attorney who has to prepare a complex brief for me, which is due at the Ventura Appellate Court November 8. My attorney is trying to help me out of difficult arrangements I have been compelled to live under for several years, so I have no reasonable choice in this matter. Unlike in my case, CSPA's, and the fish, wildlife, and stream ecosystem resources we represent, it will not be a hardship on the City if you reschedule the City's WRP hearing to a later date. That is especially true because at the City's proposed water projects hearing on March 23, 1999, which I attended and testified at, City staff told the public that the SWRCB hearing on its WRP would not be until at least January 2000. If you do not change the WRP hearing date until after Nov. 1, my SWRCB hearing testimony for both the Subject Project and the WRP will be seriously dimenished. Therefore, as the State's trust agency for the wise and balanced environmental, economic, and social use of water, I sincerely and faithfully trust that you will change the date for the WRP hearing to after Nov. 8, so I can adequately testify for CSPA on behalf of fish, wildlife, and stream ecosystem resources. III. The FEIR Did Not Adequately Assess cumulative Impacts: The SWRCB should not make a decision on the Project until the City makes an adequate assessment of the cumulative water diversion impacts of the proposed Project combined with the proposed Santa Margarita Ranch and Nacimiento A 3 Water Supply projects. The FEIR superficially discusses both of these projects on pages 3.16-3 and 3.16-6 respectively. However, it does not discuss these projects relative to cumulative adverse impacts on the Salinas River, tributaries, and related environmental resources due to the potential water diversions from all three projects. The FEIR indicates buildout of Santa Margarita Ranch could occur either under present agricultural use or under a potentially approvable Specific Plan allowing 500 dwellings and 1350 people, among other water using development as a golf course, other recreational facilities and water using agriculture. The FEIR should have assessed this admitted potential future development's use of groundwater as well as surface flow and underflow of creeks on Santa Margarita Ranch as Rinconada, Trout, Yerba Buena, Santa Margarita creeks and their tributaries. It is clear the City has been monitoring the potential water use of this type of future develpoment because the City sent San Luis Obispo County a letter on February 12, 1999 (CSPA "Exhibit AA") stating relative to the adjacent similarly proposed Spanish Oaks Ranch development (proposed houses, golf course, etc.,) in the County's jurisdiction: "The environmental review should specifically address the availability of the water supply for the proposed project....If the water supply is surface flows (creeks) or undrflow of the creek systems, then there could be impacts to the City's water supply from Santa Margarita Ranch....If the proposed project will impact surface flows in the creeks flowing through the site, which are tributary to the Salinas River, there may be an impact to the establishment of a "live stream" condition in the Salinas River and a subsequent impact to the City's water supplies from the lake." It is as important for the City to assess the cumulative impacts relative to stream water diversion on the known proposed Santa Margarita Ranch Project, as it was for the County to assess under CEQA similar impacts on the proposed Spanish Oaks Ranch development. It is now known to the City that the current developer for Santa Margarita Ranch proposes to develope 3000 acres of water- using vineyards with wells that draw from the underflow of the above stated creeks on Santa Margarita Ranch (CSPA Exhibits "F" and "AA"). Recently CSPA filed a water diversion Protest with the SWRCB relative to this proposed vineyard use of stream underflow of tributaries to Salinas River. This new proposed vineyard stream water use information plus the previously unassessed cumulative impacts associated with the proposed Santa Margarita Ranch Project require the preparation of a Supplemental EIR (SEIR). Similarly, the FEIR states eii page 3.16-6 for the proposed NacimientoWater Supply Project that p 'I would receive from this project 3380 acre feet per year (AFY). Page ES-8 of the FEIR also indicates that this proposed project would divert 17,500 AFY. With this information admitted to in the FEIR, in turn a cumulative impact analysis should have been done for this amount of annual diversion from Nacimiento River which is a tributary to Salinas River. It is not reasonable for the City to rationalize on page 3.16-6 of the FEIR that "cumulative effects between the Salinas Reservoir Expansion Project and the Nacimiento Water Supply Project are not anticipated", when immediately after the FEIR states "the City may decide to pursue the Salinas Project in the future....even if the Nacimiento Project is implemented." The absence in the FEIR of a cumulative impacts analysis of the foregoing information makes it imperative that before the SWRCB makes ' a decision on the Project, the SWRCB needs to require that the City do a SEIR making this cumulative impacts analysis on the Salinas River and its potentially effected tributaries from the combined impacts of the Subject Proposed Project and the proposed Santa Margarita Ranch and Nacimiento Water Supply projects. IV. Environmental Impacts Downstream of Salinas Dam: A. Unassessed Cumulatively Significant Environmental Impacts: Although this Project would have significant unmitigable adverse environmental impacts upstream of the Salinas Reservoir Dam (Dam) mostly related to inundation impacts, which will be covered subsequently in this testimony, much of the controversy regarding this Project has centered on adverse environmental impacts associated with reduced flows downstream of the Salinas Reservoir Dam. This is understandable when the City took the position that although their would be significant cumulative impacts downstream of the Dam, other than the existing inadequate "Live Stream Agreement" (also known as the "Dead Stream Agreement" or "Dead Fish Agreement", but hereafter referred to herein as the LSA), no mitigation was required. This is remarkable considering in October 1972 when the LSA was added as a condition of the City's SWRCB Permit, it was also determined that the LSA would only be temporary until studies could b done for appropriate flow releases from the Dam (CSPA "Exhibit J"). Yet, 2� years later, without these flow studies being done to the satisfaction and approval of the SWRCB, or no other studies ever being done regarding the environmental adequacy of the Agreement itself, the FEIR remarkably concluded the LSA was adequate mitigation even though it does not mitigate the significant cumulative impacts acknowledged in the FEIR (pages ES-17 and 5-2). To allegedly mitigate those cumulative impacts the FEIR on page ES-17 states that the City would "Consider participation in a basin-wide manaeement plan". The FEIR then states "The authority to require and implement such a basin- wide plan for the Salinas River (River) is not within the jurisdiction of the City, thus this recommendation measure is not currently considered to be feasible." A "mitigation" that is not feasible under the jurisdiction of the EIR project proponent, the City in this case, cannot be construed as mitigation under CEQA. Furthermore the FEIR never addressed the cumulative impacts of the City's existing Dam project combined with the Proposed Project. Without this cumulative impacts analysis the FEIR is inadequate and needs a SEIR for this purpose. In the matter of the FEIR never discussing the cumulative impacts of the City's existing Dam Project combined with the Subject Project, environmental issues of 'impactson downstream flows and species reliant on them must be considered. These species include common, rare, and threatened and endangered species, as the federally threatened Salinas River steelhead, S federally endangered willow flycatcher, State and federally endangered least Bell's vireo, federally threatened red-legged frog, and federally endangered arroyo toad. These species also include quite a few amphibian, reptile, bird and mammal State and federal Special Concern species. Pertaining to the federally endangered arroyo toad, I failed to discuss in my 5/5/99 letter to the SWRCB justifying preserving the CSPA Protest, that when I was on the Salinas River 4/10/99 to see the downstream most of the two private dams in the Canyon, I found a toad near the River. I am not a toad specialist and did not have with me at that time amphibian keys to help identify the toad. So I was not aware that I should have taken a photo of the tubercles on its hind feet to help identify it. But I did take several dorsal and side photos of it and still have not had time to find a herpetologist who can tell me with certainty if it is a western toad, as I suspect it is, or the endangered arroyo toad. There does faintly appear to be a pale bar across the eyes and top of the head, which is typical of the arroyo toad as indicated in several amphibian keys that I have. But the bar is so vague on this specimen that it is not a distinguishing identification feature. I have provided the SWRCB with two photos of this toad on Page 1 of CSPA "Exhibit CC". The point of this discussion and these provided photos is to seek clarification from the SWRCB or an affiliated trust agency as CDFG if it is the endangered arroyo toad. If it is, it needs to be investigated as part of a SEIR to determined if the Proposed Project would adversely impact its population in the Canyon. Although the FEIR acknowledges significant impacts on most of these species in the proposed Subject Project inundation zone above the Dam, including the listed threatened and endangered species, except for the steelhead (which the FEIR unjustifiably concludes does not likely exist in the Salinas River proposed inundation zone), it fails to acknowledge significant or any impacts on all these species downstream of the Dam. All of these species in one way or another rely on riparian vegetation along the River. And the FEIR fails to acknowledge or conclude that a 13.7% flow reduction (see FEIR page ES-17 comparing Average Flow Without Project to Average Flow With Project, and also see my 6/2/98 FEIR comment letter and my 5/5/99 letter to preserve the CSPA Protest on the Project) starting in the Salinas River Canyon (Canyon) below the Dam will have a significant impact on riparian vegetation and the mentioned species, threatened and endangered and otherwise, reliant on it. This is a serious oversight by the EIR. Even a more serious oversight is that the FEIR failed to assess the cumulative impacts of the reduced flows of the proposed Subject Project combined with the reduced flows of the City's existing Dam Project on downstream riparian vegetation and the terrestrial and aquatic species reliant on it. Based on the total inflow and outflow (Downstream Releases plus Spills) data in the table titled Appendix A of APPENDIX K ADDITIONAL HYDROLOGICAL ANALYSES DOCUMENTATION of the FEIR, for the 51 year period from the beginning of Dam diversion flow data in flow year 1944/45 to the last full year for which flow data are shown in 1994/95, historical River flows have been reduced 43 % (588,851AF [total releases + spills for the 51 years] divided by 1,041,009AF [total inflow for the 51 years] = 0.57 X 100 = 57% outflow expressed as a per cent of total inflow; 100% [historical inflows] minus 57% outflow = 43% reduction in historical Salinas River flows caused by the existing Dam Project). Reasonableness would indicate that this 43% flow reduction to the River immediately downstream of the Dam is a significant adverse environmental impact. Because the 13.7% the Subject Project would further reduce River flows is expressed as the reduction from the existing situation, which is with the Dam, this figure cannot be added to the 43%. Instead, the amount the Subject Project reduces historical River flows must be added to the 43% the existing Dam Project has reduced historical flows. It can be calf lated that the Subject Project alone will reduce historical River flows by c (from page ES-17 of the FEIR: at Base of Dam, Average [annual] Flow Without Project [meaning with the existing Dam Project] IS 14,927AFY minus Average Flow With Project [raising the Dam 19'] 12,886AFY = 2,041AFY flow reduction from the Subject Project; historical average inflows = 1,041,009AF [see above] divided by 51 years = 20,412AFY; 2,041AFY/20,412AFY = .10 X 100 = 10% reduction in historical Salinas River flows caused by the proposed Subject Project). And again reasonableness would indicate that this flow reduction to the River immediately downstream of the Dam is a significant environmental impact, or at least a cumulatively significant environmental impact. So it is also reasonable to conclude that the 53% (43% + 10%) cumulative average annual flow reduction to the Salinas River caused by the existing Dam Project and the proposed Project would be a cumulatively significant environmental impact. But the FEIR did not assess or even consider this cumulatively significant reduction in flows impact on downstream riparian vegetation and the species reliant on it. Therefore the SWRCB should not make any decision on this Project until it first requires the City to do a SEIR to assess this cumulatively significant impact on the downstream environment. And in requiring the City to do this SEIR it should also take into consideration that the Salinas River downstream (as well as upstream) of the Dam is historic or recovery habitat for the federal threatened and endangered species listed above (U. S. Fish and Wildlife Service, 1998, and 1999) and the Board should ensure in its orders to the City that this threatened/endangered species information is taken into account by the City in doing this SEIR. B. Downstream Flow Reduction Impacts to Steelhead and Other Species: In discussing the adverse impacts on Steelhead and other species downstream of the Dam, it is important to analyse the impacts the existing Dam Project has had and is having and the increased impacts the Subject Project would add to that. So in this discussion it is neither possible nor desirable to move away from adding to the previous discussion on cumulative impacts. Additionally, most of the following discussion on the downstream ecological impacts of the existing Dam Project and the Subject Project will focus on the 14 mile stretch of Salinas River in the Salinas River Canyon (Canyon) immediately downstream of the dam. For downstream impacts this is consistent with my previous EIR comment letters and my 5/5/99 letter to the SWRCB to 7 preserve the CSPA Protest on this Project (these letters are part of the SWRCB administrative record for the upcoming Oct. 12 hearing). I have focused on this downstream stretch of the River not only because the City has ignored discussing its ecological richness in the FEIR based on an erroneous assumed no impact due to the inadequate Live Stream Agreement, but because this stretch of River has great potential for steelhead and other species if adequate flows are restored to the Salinas River. Other than the ecological insult fostered on it of large past, present, and additional proposed flow reductions, the Canyon environs and the River itself are fairly pristine compared to areas downstream of the Canyon. I have also found it important and necessary to focus on this ecologically important stretch of River because mostly SLO City and north County cities along the River tend to somewhat selfishly debate the merits of the River and its extractable water downstream of the Canyon. They are themselves focused on the economic value of the River's water and unfortunately give little attention to its ecological attributes, especially to those in the Canyon which are mostly out of sight and out of mind with very few public human access points. But it is that inaccessibility that leads to relative pristineness lending the Canyon to great environmental potential, if adequate water can be restored to the River within! And if that water can be returned to the River, it will have great benefit for steelhead and manyother species. Adding water back to the River within the Canyon also has the enormous environmental benefit of in turn adding needed flows to the River for approximately 130 miles downstream of the Canyon .all the way to the Pacific Ocean. project Consistently throughout my oral testimony on the proposed SubjectAand my EIR comment letters on it (part of the SWRCB administrative record), I have requested from the City to no avail that they do flow and hydrology analysis in this important Canyon stretch of the Salinas River. I believe they refused to do this perceiving any attempt to do it as a further admission of the Subject Project's likely significant impact on the Canyon stretch. It was simply easier for them to consistently in return in the EIR and Project meetings state that the LSA would mitigate any significant/cumulatively significant impacts from flow reductions combined with runoff flows that would be generated from within the Canyon watershed (FEIR, page ES-17 and 5-1). But the avoidance of a lead project proponent CEQA agency from the very beginning of an EIR process to assess impacts on an ecosystem based on the assumed/presumed adequacy of (1) past environmentally unanalysed "mitigations", as in the case of the LSA, or (2) existing conditions, as flows generated only from the mostly narrow Canyon watershed, to mitigate those impacts is clearly illegal under CEQA. CEQA requires an assessment of impacts and any past unanalysed "mitigations" or existing conditions before any conclusions can be drawn on those impacts and the ability of past "mitigations" and conditions to reduce them to less than significant/cumulatively significant. Because the City shirked its CEQA responsibilities and basically provided no hydrologica! or flow data for the Canyon stretch of River, other than to indicate the proposed Project will reduce the average annual flows from the 8 current situation by 13.7% (documented previously herein from the FEIR), CSPA with very limited monetary resources has had to provide some reasonable approximation analysis of these flow reductions at various points in the Canyon to demonstrate the significance/cumulative significance of past, present, and proposed flow reductions associated with this Dam project. It has previously been shown herein that the cumulative flow reduction to the River immediately downstream of the Dam caused by the existing Dam and the Proposed Project is 53%. This does not give an idea of what the flow reductions would be at different points on the River further downstream in the Canyon. Furthermore this average annual cumulative flow reduction figure does not give an idea of what the flows in the Canyon are with the existing Dam and would be with the Proposed Project. The reality is that in the Canyon during the annual rainy season (primarily November through April for the mediterranean type climate of the Central Coast area of California) the Dam captures nearly all of the flows generated from the approximately 134 square mile watershed upstream of the Canyon and Dam (This approximately 134 square mile watershed is determined from the approximately 112 square mile Salinas River watershed upstream of Salinas Reservoir given on page 3.4-2 of the FEIR added to the approximately 21.85 square mile watershed of the Reservoir itself which is in Appendix B of CSPA geotechnical consulting engineer Leon Chaulet's written testimony for the Oct. 12 SWRCB hearing). I stated that the Dam captures nearly all of the rainy season flows because for the 52 year period (1943/44 - 1994/95) Appendix A of the FEIR's ADDITIONAL HYDROLOGICAL ANALYSES DOCUMENTATION (APPENDIX K) provides rainy season flow data, it can easily be calculated that only 1.7 cfs (cubic feet per second) flows on average have been released from the Dam for the rainy season months of November through April. The only factor nee4ed for calculating this 1.7 cfs amount from the Downstream Releases inA F column in APPENDIX K of the FEIR i I nv r io. i fja,,€€tyor of 2AF per day is equivalent to I cfs per day (therefore: tota -+ or tie W'- year, 6 month rain season = 32,418AF divided by the total number of days in the 52 year, 6 month rain season [9516 days] = 3AAF per day divided by 2 [2AF/day = lcfs] = 1.7cfs downstream releases). The only time the flows in the River in the Canyon are not almost entirely generated from the.. narrow Canyon . watershed itself is in those uncommon occassions when the Dam spills during the rainy season. The Yearly Spill Data figure in APPENDIX K of the FEIR (a page number is not provided for this figure in APPENDIX K) shows that for the 51-year period of spill data records (1945-1995) since the Dam was built there has only been 16 years with spills and with the Proposed Project there would only be 15 years with spills. And in 10 of those years spills with the Proposed project would be reduced significantly by 209o' or more from the spills without the Proposed Project. And in either situation it is obvious spills from the Dam are uncommon during the raining season-- on average every third year at most, or about 33% of the time. Except for uncommon spill years, given the refusal of the City to do flow analysis in. the Canyon relative to the existing Dam and the Proposed Project, c! CSPA provides the following idea of the Dams past, present, and proposed flow reductions to the Salinas River in the Canyon based on our limited personnel and monetary resources. Rain falling on the Salinas River watershed generates flows in the Salinas River. Prior to construction of the Dam the Salinas River in the Canyon had the benefit of the entire watershed above the site of the Dam as well as the watershed in the Canyon for generating its flows. When the Dam was installed and the City in the early 1940's started capturing nearly all of the rain season flows from the watershed upstream of the Dam, as previously discussed, thereafter flows in the River in the Canyon were severly restricted to being generated from within the narrow 14-mile long Canyon and its few side canyons along Pilitas, Rinconada, and Calf Canyon creeks. Regardless of what the amount of flows would have been during a particular storm or series of storms without the Dam, with the Dam the flows would be reduced generally proportional to the upstream area of watershed eliminated by the Dam. So at each successive point along the River in the Canyon it can reasonably be determined how much the flows have been reduced by the existing Dam Project. To get the fraction of the watershed remaining for flow generation at any given point along the River in the Canyon, the watershed of the Canyon between that point and the Dam is divided by the entire Salinas River watershed upstream of that point. This fraction -i-rr can then be converted to percent (multiply by 100) to get the percentage of watershed remaining to generate flows on the River at this point after the Dam was built. Since watershed area is generally directly related to flows generated, this percent of watershed remaining after the Dam was constructed gives a reasonable approximation of the percentage of flows remaining in the River at that point after the Dam was built, as compared to the flows that would have existed at that point on the River prior to the construction of the Dam. To make these flow approximations at several critical points along the River in the Canyon, the watershed area in square miles in the Canyon upstream of these points has been provided in Appendix A of CSPA geotechnical consultant Leon Chaulet's written SWRCB testimony. For example, it can be determined that after the Dam was built, the percent of watershed remaining to generate River flows at the point just upstream of Pilitas Creek, which is about 2 miles downstream of the Dam, is 1.4% of what it would have been prior to construction of the Dam (1.95 sq. mi. divided by 1.95 sq. mi. + 134 sq. mi. (the watershed area above the Dam] = 0.014 X 100 = 1.4%). In other words, 2 miles downstream of the Dam, only about 1.4% of the watershed remains after the Dam was constructed to generate flows in the River at this point. So only about 1.4% of the historical flows will exist in the River at this point during the rain season, except when the infrequent spills occur. Or conversely the River flows at this point on the River have been reduced approximately 98.6% from what they would have been before the Dam was built. Calculated in the same manner as above, the approximate percent that flows have been reduced by the existing Dam Project at the various other points along the River in the Canyon shown in Mr. Chaulet's Appendix A are: (1) co about 2 miles downstream of the Dam just below the River's confluence with Pilitas Creek, 3.6%, (2) about 4 miles downstream of the Dam just upstream of Rinconada Creek, 90.8% (3) about 4 miles downstream of the Dam just below the River's confluence with Rinconada Creek, 81.9%. (4) about 9.5 miles downstream of the Dam just upstream of Calf Canyon Creek, 7 .8%, (5) about 9.5 miles downstream just below the confluence with Calf Canyon Creek, 74.9%, and (6) about 14.3 miles downstream of the Dam at the mouth of the Canyon just upstream of Santa Margarita Creek, 72.6%. To give more insight to what these existing Dam Project caused flow reductions to the River in the Canyon mean, one can easily determine from Appendix A of APPENDIX K of the FEIR what the- inflows to the Reservoir have been during the 6 month rain season for the 52 year period inflow records are provided. Then one can use the above percent flow reduction figures to see how the existing Dam Project has reduced those flows on average during the rain season for 52 years at these various River points in the Canyon. One can calculate the average 52 year rain season flow in cfs the same way the 1.7 cfs average Downstream Releases were previously herein determined for the 52 year rain season period. The average inflow (which is basically equivalent to the historical flows in the River if the Dam had not been built) for the 52 year, 6 month rain season is 52.7 cfs (total inflow for the 52 years 6 month rain season = 1,003,504AF divided by the number of days in the 52 year, 6 month rain season [9516 days] = 105.5AF per day (AFD) divided by 2 [2AFD = icfs] = 52.7 cfs inflows or historical flows in the River if the Dam had not been built). Therefore, in considering that this 52.7 cfs represents a reasonably average flow in the River during the 6 month rain season if the Salinas Dam did not exist, then one can in turn use the previously calculated percentages at points on the River in the Canyon to determine how much the existing Dam Project has reduced the flow in the River at those points. These reduced flows must then be increased by 1.7 cfs, which is the average Downstream Releases previously calculated herein for the 52 year, 6 month rain season. Except in those uncommon years when there are Dam spills (slightly less than 33% of the years), these Dam caused rain season reduced flows for slightly over 66% of all years are: (1) 1.7 efs flows at the base of the Dam (since there is no watershed contributing to the River in the Canyon at the base of the Dam, the only water that would be in the River at this point is the 1.7 cfs contributed by the Downstream Releases during the rain season); (2) 2.4 cfs about 2 mile downstream of the Dam just upstream of Pilitas Creek (10017o - 98.6%a = 1.4%; 1.4% of 52.7 cfs = 0.7 cfs; 0.7 cfs + 1.7 cfs = 2.4 cfs); (3)-L.1 cfs about 2 miles downstream of the Dam just below the River's confluence with Pilitas Creek (100% - 93.6% = 6.4%; 6.4% of 52.7 cfs = 3.4 cfs + 1.7 cfs t 5.1 cfs); (4) 6.5 cfs about 4 miles downstream of the Dam just upstream of Rinconada Creek (100% - 90.8% = 9.2%; 9.2% of 52.7 cfs = 4.8 cfs + 1.7 cfs = 6.5 cfs); (5) 11.2 cfs about 4 miles downstream of the Dam just below the River's confluence with Rinconada Creek (100% - 81.9% = 18.1%; 18.1% of 52.7 cfs = 9.5 cfs + 1.7 cfs = 11.2 cfs); (6) 12.9 cfs about 9.5 miles downstream of the Dam just upstream of Calf Canyon Creek (100% - 73.8% = 21.2%; 21.2% of 52.7 cfs = 11.2 cfs + 1.7 cfs = 12.9 cfs); (7) 14.9 cfs about 9.5 miles downstream of the Dam just below the River's it confluence with Calf Canyon Creek (100% - 74.9% = 25.1%; 25.1% of 52.7 cfs = 13.2 cfs + 1.7 cfs = 14.9 cfs), and (8) 16.1 cfs about 14.3 miles downstream of the Dam at the mouth of the Canyon just upstream of Santa Margarita Creek (100% - 72.6% = 27.4%; 27.4% of 52.7 cfs = 14.4 cfs + 1.7 cfs = 16.1 cfs). Since each of the above highlighted flow amounts is a reasonable approximation of the flows in the River at various points in the Canyon resulting from the reduced flows caused by the Existing Dam Project, one can determine the approximate flows that would occur in the River at these points in the Canyon if the Dam had not been built by adding 52.7 cfs to each of the above highlighted flow amounts. The only other adjustment that would then need to be made to these flow amounts if the Dam did not exist is to subtract from each amount the 1.7 cfs Downstream Releases, since there would be no such releas6s if the Dam did not exist. Therefore, after making these adjustments, the approximate flows that would be in the River at these same points in the Canyon if the Dam had not been built are,. in the same sequence as above: (I) 52.7 cfs, (2) 53.4 cfs, (3) 56.1 cfs, (4) 57.5 cfs, (5) 62.2 cfs, (6) 63.9 cfs. (',) 65.9 cfs, and (8) 67.1 cfs. From comparing the corresponding flows in the above 2 paragraphs for each point in the Canyon with and without the existing Dam Project, one can see that the existing Dam Project has for over the past half century since its construction in 1941 caused more than simply unspecific significant flow reduction impacts. It has caused enormous flow reductions to the River throughout the Canyon from the Dam to the Canyon mouth 14.3 miles downstream. These enormous flow reductions ranging from 98.6% at the base of the Dam to 72.6% at the Canyon mouth indicate that even without the EIR doing analysis for significant and cumulatively significant impacts to the Canyon River ecosystem, steelhead and other aquatic and terrestrial River and riparian species .would be significantly impacted. In fact, even though mounting evidence exists that steelhead still use the River in the Canyon, flow reduction of this great a magnitude certainly had a significant impact on the numbers of steelhead using the Canyon stretch of River. Previously herein I showed that from APPENDIX K of the.A*a+-FEIR, it could be determined from the EIR data that on average flows have been reduced in the Salinas River at the base of the dam about 43%. This figure, even though itself dramatically indicating the long-term flow reductions that have occurred to the River below the Dam, does not correspond to the- much higher approximately 98.6% flow reductions below the Dam to 72.6% flow reductions at the mouth of the . Canyon that I have subsequently calculated herein. The main reason for this sizeable difference is the 43% figure determined from EIR data includes uncommon but often large spills. These large but uncommon spills when averaged in with the frequent but much smaller Downstream Releases, yield an average flow reduction from the existing Dam Project that is considerably less than the flow reductions that actually occur in the Canyon stretch of the River during the 6 month rainy season. One can see how the infrequent (occuring about every third year) but large Spills distort the average flow reduction which includes the much smaller Downstream Releases by a simple analysis of flow data in Appendix A in APPENDIX K of the FEIR. It can be calculated from Appendix A that Spills total tz 530,600AF of the 588,851AF total outflow (Spills + Downstream Releases) from the Dam over the 51 year period data are provided, whereas Downstream Releases total only 58,251AF of the 588,851AF total outflow. Therefore, although Spills occur only about 33% of the years and typically for only a few months out of the year when they do occur, as compared to Downstream Releases, which occur 100% of the years and typically year round, the former have yielded 900/v (530,600AF of Spills divided by 588,851AF total outflow X 100 = 90%) of the total Dam outflow and the latter only 10% (58,251AF of Downstream Releases divided by 588,851AF total outflow X 100 = 10%) of the outflow over this 51 year period since the Dam was built. The reality of this analysis for steelhead and all other species utilizing the River/riparian ecosystem and for the River/riparian ecosystem itself is that except in those few months of the year in those infrequent years when spills occur, all .the rest of the greater number of years and much greater number of months, there is dismally inadequate flows in the River to prevent significant and. cumulatively significant adverse impacts to these species and the River/riparian ecosytem. The forgoing discussion has focused on flow reductions to the River in. the Canyon caused by the existing Dam Project to give one a better idea of the significant and drastic effects it has had on the River in the Canyon and in turn on the species, as steelhead, reliant on it. In this respect, one will better be able to now understand the significant and especially cumulatively significant adverse impacts the Proposed Subject Project would have on this Canyon riverine ecosystem if the Dam is raised 19' and flows are reduced even more in the stretch of River in the Canyon, as well as further downstream. This discussion can be brief because any additional flow reduction, large or small, to the River in the Canyon caused by any project including the Proposed Project will clearly have a cumulatively significant adverse impact when combined with the significant impact the existing Dam Project already has had. So when one considers, as earlier shown herein from the .EIR (page ES-17 and Appendix A of APPENDIX K) that the Proposed project would reduce flows immediately downstream of the Dam 13.7% from the existing flow situation in the River, or 10% from the historical flow situation in the River if the Dam had not been built, this amount of flow reduction, which is likely significant in itself, when added to the already discussed significant and drastic flow reductions caused by the existing Dam Project, will cause cumulatively significant impacts to the Salinas River ecosystem in the Canyon. I stated above that the Proposed Project would, besides causing cumulatively significant impacts with the existing Dam Project, also likely itself cause significant impacts to the River stretch in the Canyon. However, this latter determination is difficult to state with certainty because inappropriately and illegally under CEQA the City refused to assess this potentially significant impact on the Canyon riverine ecosystem simply stating in the FEIR without any analysis that, one, the LSA (page ES-17). and, two, winter flows downstream of the Dam during wet years (page 5-1) would adequately mitigate downstream impacts. I have previously addressed the latter with discussion and data showing that whether during wet years or dry years, when the Dam blocks nearly all the 13 flows from the River upstream of the Canyon, there is very little flow generated in the narrow Canyon watershed itself to compensate for the much larger upstream flows that have been blocked off by the Dam that the River ecosystem in the Canyon was in the past reliant on. Furthermore the FEIR (page ES-17) contradicts itself and comes to the same conclusion I have for the significant/cumulatively significant downstream impacts of the Proposed Project during wet years when under the heading Potentially Significant Impacts it states "Potential adverse hydrologic or hydrogeologic effects in the Salinas River downstream from the reservoir due to decreases in downstream flows during the winter months of above normal rain years." Then the FEIR leaves this impact unmitigated when on the same page under the heading Residual Impact it states for this impact "Insignificant (project specific) to Significant (cumulative)". With this FEIR contradiction and admission to . an unmitigated cumulatively significant downstream riverine impact, as .previously stated herein, the SWRCB should require the City to do a SEIR on this FEIR admitted cumulatively significant impact. And the SEIR should this time do an indepth study of the impacts of the Proposed Project on the River ecosystem in the Canyon to truly and honestly help determine if there will be significant as well as cumulatively significant impacts to this downstream ecosystem. Because the FEIR also said the LSA will mitigate downstream flow reductions caused by the Proposed Project, I will now specifically address the LSA relative to its inadequacy for mitigating downstream flows. B. The Inadequacy of the Live Stream Agreement to Mitigate Project Flow Reductions: I thoroughly discussed the inadequacy of the LSA to mitigate significant and cumulatively significant adverse impacts from reduced flows in the Salinas River caused by the existing Dam Project and that would be caused by the Proposed Project in my letter of 5/5/99 to the SWRCB to preserve the CSPA water diversion Protest on this Project. Although my 5/5/99 letter is already part of the administrative record for the Oct. 12 hearing, as a convenience and courtesy to the SWRCB members, CSPA is also submitting it as CSPA "Exhibit DD", but this time without its 5 exhibits, which you already have in the record (including in its "Exhibit 1" 14 color photographs downstream and upstream of Salinas Reservoir as part of .my 6/2/98 FEIR comment letter, and in its "Exhibit 2" 8 color photographs downstream and upstream of the Reservoir directly referred to in the narrative of my 5/5/99 letter to the SWRCB). Since CSPA has provided you with my 5/5/99 letter in the above two manners, I will not repeat here as my written testimony for the Oct. 12 hearing everything I said in that letter relative to the LSA or anything else discussed subsequently in this letter, as significant unmitigable impacts the Proposed Project would cause upstream of the Dam primarily by inundation. Instead in this written testimony herein, I will summarize what I covered in my 5/5/99 letter to you on these relevent environmental issues and cover in more detail new information available to me on these relevent environmental issues since I provided you with the 5/5/99 letter. As I have already discussed herein, I have focused on the past, present, and proposed adverse impacts of the Salinas Dam Project in the Canyon stretch of l� the River and I will do it relative to the LSA also. As I said in the 5/5/99 letter, I believe the Canyon stretch of the River is being seriously (and likely negligently) environmentally overlooked in the operation of the already inadequate LSA. I essentially stated in my 5/5/99 tetter that I knew of no one associated with the Project or otherwise that was checking for a "visible flow", as required by the LSA, in the Canyon area. Since then I think someone told me unofficially that a "visible" LSA flow is checked for at the Highway 58 Bridge, which is about 9.5 miles downstream of the Dam. Even if the LSA is checked for compliance at this Bridge, that leaves 9.5 miles of River below the Dam that is not checked for LSA compliance. Furthermore, the fact that the River might be checked at the Highway 58 bridge does not mean even if a visible flow is seen in the River at the Bridge, one exists for the next approximately 4.8 miles downstream to the mouth of the Salinas River Canyon. Also I stated in my 5/5/98 letter that I was concerned flows were not being released from the Dam often enough and in quantitites enough to provide adequate scouring to create fish and other aquatic species' cut bank, pool, riffle, and run habitat, and to provide necessary scouring function for the regeneration of riparian vegetation. I have seen nor heard nothing since to change my concern on these impacts not being addressed by the LSA or other Dam releases. And I expressed concern in the letter that in the low flow season (typically late spring, summer, and early fall often coinciding with May through October) flows were not being released in a persistent and sustained manner to scour (flush) the runs and riffles clean of silt so clean gravels would aid in the nursery and rearing stages of young fish, as juvenile steelhead, native western suckers. etc.. I am now even more worried than then about this concern for the following reasons. As I mentioned in the 5/5/99 letter, I was on Mr. Otto Schmidt's property in the Canyon on 4/23/99. And I further stated that contrary to the FEIR indicating that there would be no Proposed Project specific significant downstream impact due to the unaltered existence of the LSA, the LSA was clearly not preventing significant impacts to the River that day because I estimated there was less than 1.0 cfs flow in the River that day. I supplied two color photos numbered I and 2 in Exhibit 2 of my 5/5/99 letter to the SWRCB documenting this less than 1 cfs flow on 4/23/99. I am also supplying the Board with two more photos on Page 2 of CSPA "Exhibit CC" for the Oct. 12 SWRCB hearing showing this terribly inadequate flow for the Salinas River ecosystem and species reliant on it as steelhead. I also indicated in my 5/5/99 letter that this lack of nearly any flow was allowing gravel beds to silt over and riffles to dry up. And I stated that just a few days before, on 4/17/99, I was on the Salinas River immediately upstream of the Reservoir and estimated significantly greater inflows into the Reservoir. Now that CSPA has acquired the daily flow data for most of the years that the LSA has been in existence (CSPA "Exhibit K"), the days of 4/17/99 and 4/23/99, when I was on the River, indicate a possibly more alarming situation than I previously expected relative to the inadequacy of the LSA for maintaining fish and their habitat in good condition, as required at all times downstream of a Dam by Fish and Game Code 5937. According to the inflow data for 4/17/99 r� when I was on the River above the Reservoir, 65.5AF flowed into the lake that day, or 32.75 cfs inflows (2AF per day = lcfs per day), which is a fairly significant inflow for most years at the very end of the rain season. In light of this amount of flow in the River upstream of the Reservoir, one can see how environmentally inadequate in comparison virtually no flow being released from the Dam just a few days later on 4/23/99 would be. But before this harsh a conclusion can be drawn, one must look at what the flow in the River above the Reservoir was not on 4/17/99 but instead on 4/23/99,• the day I saw virtually no flow in the River below the Dam at about 4pm, which is when I took all the photos just referred to and that CSPA has supplied to the SWRCB. The inflow to the Reservoir for 4/23/99 was 23.16AF, or 11.6 cfs. Clearly the natural flowing River upstream of the Reservoir was rapidly declining in flows this late in the rain season, which would be expected. But 11.6 cfs flow in the River above the Reservoir is still a decent mid spring flow for the River upstream of the Reservoir. However the Downstream (flow) Releases from the Dam for 4/23/99 were 0.13AF, or about 0.07 cfs, which confirms what I saw that day and what the 4 CSPA photographs at your disposal for viewing likewise show. In fact, the flow data in CSPA "Exhibit K" show not only 0.07 cfs Downstream (flow) Releases for 4/23/99, but 0.07 cfs releases for the entire months of March and April, even though the average daily inflow for these two months was 54AF, or 27 cfs (calculated from the Inflow totals for 3/99 and 4/99 in CSPA "Exhibit K"). No other conclusion can be reached from a fisheries management perspective that late winter and early springtime (as represented by the two months of March and April) flow releases of 0.07 cfs is a human caused catostrophe to the Salinas River ecosystem in the Canyon and further downstream. Even if Salinas River tributaries downstream of the Canyon are providing a "visible flow" in the Salinas River down to its confluence with the Nacimiento River about 20 miles downstream from the Canyon, this does not mean compliance with the already inadequate LSA when no flow is being provided to the Canyon stretch of the River and all the species residing in or otherwise relying on the River. The LSA has been a political hoax and a highly biased Agreement in favor of SLO City at the great environmental/ecological expense of the Salinas River. It hides behind the non-ecological notion that the Salinas River ecosystem in the Canyon and further downstream can healthily survive on a mere "visible" trickle. Fish as juvenile steelhead and other aquatic species cannot live in a visible trickle, but instead must have adequate flows to carry on all of their life cycle stages throughout a given year and in sequential years. In fact the LSA has acted to harm the River system more due to its existence than if it did not exist. For example, CSPA "Exhibit U titled One Hundred Years of Rainfall Trends in California shows on Figure 1 that the average annual rainfall for all of California from about the end of the early 1940's when the City began taking water from the River coincided with a somewhat less than average period of rainfall up to about the time of the beginning of the LSA in 1972. Thereafter, Figure 1 shows an overall period of somewhat greater than average rainfall coinciding with the LSA period of time, other than, the drought period in the late 1980's. This same rain trend is shown for most 16 regions of the State including the Central Coast on Figure 2 of CSPA "Exhibit U (see also CSPA "Exhibit M"). However, the River's inflow bounty to the Reservoir in a period of overall good rain years, need not be shared as outflow to the River downstream of the Dam. This problem derives from the LSA only requiring that a visible trickle be seen in the River downstream of the Dam even in wet years, .or if a visible trickle cannot be seen, then all thel` flows equivalent to the inflows must be released from the Dam. But, to the benefit of the City, often when the latter situation developes and no flows are visible downstream as per the LSA, no flows have to be released because by that time it is either late in the year or in a drought period when no flows exist in the Salinas River entering the Reservoir. One can see what a dismal record the LSA has had for the downstream River by comparing Inflows to Downstream Releases since the LSA was crafted in 1972. The average daily Inflow to the Reservoir over the 23 year period since 1972 that data is provided in Appendix A of APPENDIX K of the FEIR is 68AF (574,337AF Inflow divided by 8395 days [23 yrs. X 365 days/yr.] ), or 32 cfs. In comparison the outflows over this same period are very small. From Appendix A it can easily be determined for the 23 year LSA period how many months fell into different average AF per day (AFD) categories (by dividing the AF released for each month by 30.5 days/month to get average AFD for each month) for Downstream Releases, as 0 AFD, 1 AFD, 2 AFD, 4 AFD, 6 AFD, 8 AFD, 10 AFD, etc.. Then, because fisheries scientists do not typically communicate in AFD flows, but rather in cfs flows, these AFD flows were converted to cfs flows using the conversion 2 AFD = ]cfs. This determination from Appendix A Downstream Releases data gave the following number of months with the following cfs Downstream (flow) Releases during the 23 year LSA period: 45 months with 0 cfs, 74 months with less than 1 cfs, 41 months with between 1 and 2 cfs, 33 months with between 2 and 3 cfs, 25 months with between 3 and 4 cfs, 9 months with between 4 and 5 cfs, 29 months with between 5 and 8 cfs, 5 months with between 8 and 10 cfs, 2 months with between 10 and 20 cfs, and O months with over 20 cfs. This information shows that for the 23 year period flow data is available since the beginning of the LSA, (1) 5990 of the months had Downstream Releases of less than 2 cfs. (2) 88% of the months had Downstream Releases of less than 5 cfs. (3) 98% of the months had Downstream Releases of less than 8 cfs, and (4) 99% of the months had Downstream Releases of less than 10 cfs. These Downstream Releases figures are paltry in comparison to the average monthly Inflow of32 cfs for the same 23 year period since the beginning of the LSA. Spills marginally augment these flows in the years they occur, but as already discussed herein, over the long term spills do not occur in enough of the years and in enough of the months (only a few months during the rain season) of the years that they do occur. So, relative to the impacts of the LSA on the River ecosystem, Spills are of no help to Downstream Releases for the great majority of the months when the only outflow from the Dam is Downstream Releases. In fact, Appendix A shows that of the 276 months in the 23 year LSA period, only 29 months had spills, or only 10.5% of the total months had spills. And this 17 10.5% figure is higher than what can be expected over the longer term, since Appendix A shows that for the 624 months of the 51 complete years (1944/45 to 1994/95) for which Dam flow data is compiled, only 47 months had spills, or only 7.5% of the total months for the 51 year period had spills. So these few spill months do not augment flows for the great majority of the months (92.5%) that the downstream River must receive all of its flows from the Downstream Releases operation of the Dam! The LSA with its assumption that a visible trickle meets all downstream users vested water rights, including fishes' vested water rights under Fish and Game Code 5937, has led to the unteniable and unacceptable Downstream Releases in comparison to River inflows as analysed and discussed above. Also, as I discussed in my 5/5/99 letter to the SWRCB, adequate flow releases unaddressed by the miserly LSA are needed for upstream migrating adult spawning steelhead to pass over the two small private Dams on the River in the Canyon. I already provided my opinion with discussion in my 5/5/99 letter that these two Dams do not constitute a migration barrier to spawning steelhead if adequate flows exist in the River so steelhead can pass over the spillways of these Dams. In Exhibit 1 of my 5/5/99 letter I provided the SWRCB with two color photographs (labelled 1 and 2) taken 5/30/98 of the upper small dam and its spillway. These 2 photographs show adequate flows passing over the spillway for fish such as steelhead to migrate upstream over the dam, or for downstream migrant fish such as adult and juvenile steelhead to swim downstream past the dam. However, the 2 photos labelled 1 and 2 previously discussed herein taken on 4/23/99 and provided to you in Exhibit 2 of my 5/5/99 letter to the SWRCB, and the two additional photos being provided to you on Page 2 o�SPA "Exhibit CC" for the Oct. 12 hearing show the herein discussed 0. cfs Downstream Releases for 4/23/99, which is not nearly adequate flow for fish to migrate up or down stream in the spillway to get past this upper small dam. I also provided the SWRCB with two photos labelled 3 and 4 in Exhibit 2 of my 5/5/99 letter to the SWRCB showing the lower small dam in the Canyon on 4/10/99 with what I estimated to be inadequate flows for spawning steelhead to jump and swim over the spillway that particular day. But I made it clear that with adequate flows, perhaps 10 cfs or slightly more, steelhead would be able to jump and swim over the spillEway for this Dam. Besides the 2 photos of this small dam and spillway I have already supplied you with in my 5/5/99 letter, I am providing you with on Page 3 of CSPA "Exhibit CC" two more photos of this dam and spillway also taken 4/10/99. One of these photos shows a 6' tall man standing. next to the spillway. The point of this photo is that, as it is well within the ability of adult steelhead to jump over 6' high instream obstacles, as the approximately 6' verticle part of the spillway shown adjacent to the man, it can be seen from the photo this dam and its spillway are not a barrier to upstream migrant adult spawning steelhead, if adequate flow is in the River. It should also be noted from this photo that the upper few feet of this spillway just above the height of the man's head, is not verticle, but instead angled in such a way that once a steelhead jumps the 6' verticle part of L8 the spillway and lands on this angled portion, all it has to do to finish passing over the spillway is to swim over these last few feet of the spillway. The other photo on Page 3 of CSPA "Exhibit CC" has been provided to you to show the overall configuration and size of this instream private dam. Although I have determined that these dams and their spillways are not migration barriers to upstream and downstream migrating steelhead and other fish if adequate flows are in the River, the spillways of both dams need to be reworked to be even more friendly to migrating steelhead and other fish. Steelhead likely have vested rights to the River prior to these dam owners, and it is incumbent on these people to ensure their spillways are easily passable by steelhead. In this regard, both spillways need assessement for some rehabilitation work for easy passage of steelhead and other fish. I believe these spillways should be reworked so spawning steelhead and other fish could jump and swim over them not only in medium to high water conditions but also in the low flow water conditions of a drought or the seasonal low flow conditions of summer and fall. Also in my 5/5/99 letter to the SWRCB I stated that there is adequate proof spawning steelhead can pass upstream over the downstream dam in the Canyon. That proof was given in my letter in the form of recent personal professional fisheries communication between Mr. Chuck Marshall, a local Calif. Dept. of Fish and Game (CDFG) fisheries biologist, and myself. I stated in my 5/5/99 letter that Mr. Marshall confirmed to me 'that in 1997 he and others were shown a 24" frozen steelhead by the owner of the property of the upstream private dam in the Canyon. The owner had told Mr. Marshall and the others that he caught the large steelhead in the pool below his dam, which attests to this fish migrating over the downstream dam in the Canyon. I also stated in the 5/5/99 letter that Mr. Marshall had told me that based on his seeing this 24" fish, he was sure it was a native steelhead and not a trout that had been stocked in Salinas Reservoir and washed over the Dam during high water. Since I sent the SWRCB my 5/5/99 letter, I have again talked to Mr. Marshall and he reconfirmed to me that in his expert opinion the 24" fish was a steelhead and not a planted trout. And as I indicated in my 5/5/99 letter, Mr. Otto Schmidt, who owns the property just downstream of the upstream dam, has also told me about this 24" steelhead, as well as other personal knowledge he has regarding catching steelhead in the Canyon stretch of the River below the Dam (see CSPA "Exhibit Z"). In my opinion the most noteworthy information Mr. Schmidt has told me about regarding catching steelhead in the past, were the juvenile steelhead in the approximately plus or minus 6" size range he caught and released in 1997. He described these fish to me as being sleek, in good condition, and with healthy completely intact fins. The description of these fish fit that of what one would expect for juvenile steelhead in the River; and was significantly different from the larger, poorly conditioned, frayed and clipped finned rainbow trout Mr. Schmidt caught on 5/30/98 when I was with him. I believe that it is likely these larger trout in the 10" to 14" size range were fish that washed over Salinas Dam during that El Nino winter. A photo that I took on 5/30/98 of one of these larger, non-steelhead, stocked rainbows that Mr. Schmidt had just caught in the River on his property is on Page 4 of CSPA "Exhibit CC". This fish is not at all like the small, sleek juvenile steelhead Mr. Schmidt described to me and caught the year before on his property. Because it is incumbent for the recovery of steelhead in the Salinas River and specifically in the 14 mile Canyon stretch of the River that they have unbridled, and easy access over the two private dams in the Canyon, progress needs to be made on this issue. Therefore, as part of the SWRCB's overall work on water issues of the Salinas River, it and other water and natural resource public trust agencies should start working immediately with the owners of these two dams and all other interested parties as CSPA to ensure these two private dams and their spillways in the Canyon stretch of the River are as easy as possible for migrating fish as steelhead to pass over in both directions and in high and low flow conditions. C. Resolving the Live Stream Agreement and the City's Proposed Subject Project: The City has huge, complex, unresolved environmental, economic and social issues associated with the existing Dam Project. These issues as demonstrated by the long paper trail of SWRCB Permit extensions and proceedings on such extensions on multiple issues that .become more convoluted as one researches into the overall issue of the City's existing and Proposed Dam projects are going to be extremely difficult for all involved to solve without adding to the problem more water diversions from the Proposed Project. It is time, hard and tough, or not, for the City to not only acknowledge that it has taken all the water it possibly can from the Salinas River under the existing Dam Project, with much undone mitigation remaining to be done on that issue, without continuing to try to add the likely forever unresolvable, unsolveable issues and impacts of the Proposed Project. The LSA by most accounts but the City's has been an environmental/ecological failure. And such a failing form of alleged mitigation must not from this point on be allowed by the SWRCB, CDFG, or anyone else to be promulgated across the State and land as bonified stream flow mitigation worthy of being carried forth into the new century and millennium. The tenacity of the City to cling to this unstudied, untested Agreement without any other idea in their massive set of FEIR documents how to resolve the downstream environmental, water rights, and all other matters of issues., is strong admission in itself the Proposed Project is not doable. Before the City' has any right to pursue this water dream, it must come to grips with reality and help solve all the complex issues left hanging with the existing Dam Project. For the River ecosystem it cannot be assumed that the LSA based on a mere .visible" trickle is adequate for meeting the vested rights of the River ecosystem including steelhead, other fish and aquatic species, and terrestrial species dependent on it (see CSPA "Exhibit Y"). These vested rights of fish and their River habitat go back in law before the Corps of Engineers hurriedly built the Dam in WWII years. without due regards for downstream water rights because of the emergency nature of those times. Somehow the City still thinks an equivalent emergency is facing it and the citizens it always alleges to represent. I live in SLO City and it does not represent me or others concerned about the environment/ecosystem on this issue. zo California Fish and Game Code 5937 states "the owner of any dam shall allow sufficient water at all times to pass through a fish way, or in the absence of a fishway, allow sufficient water to pass over, around or through 'the dam, to keep in good condition any fish that may be planted or exist below the dam." This Code section dates to 1937 and was prior to that Code Section 637 dating back to 1915 (see CSPA representative Felix Smith's written testimony for the Oct. 12 hearing). This establishes fishes' vested rights to adequate water in the Salinas River 1pelow the Dam for their "good" condition (which definition is also supplied 4VMr. Smith in his written testiminy) prior to the Corps' or the City's early 1940's Permit rights to the diverted water. Appropriating pre-vested water without adequate study of the previous rights to that water during war years is one thing, but continuing to do the same thing 55 years later still without adequate analysis and study of thoserights is another. The City needs to know that people interested in protecting the Salinas River ecosystem downstream of the Dam will not relinquish the River ecosystem's, including fishes' vested pre-City appropriations ef- alinas River water. tty ►ts Also the highest question has to be does the City actually hold any appropriations rights to Salinas River water? This is based on the pre-City vested rights to Salinas River water as per Code Sectio 937 and on other downstream users various rights to such water. TheJdWrights are clearly manifest in ORDER FOR RECONSIDERATION OF "ORDER GRANTING EXTENSION OF TIME ON CERTAIN PERMITS, IMPOSING CLARIFYING PERMIT TERMS, AND REVOKING CERTAIN PERMITS TO APPROPRIATE WATER" DATED JUNE 1, 1972 (CSPA "Exhibit J"). Page 4 of this Order states: According to the Corp's operations and maintenance manual for Upper Salinas River Dam, the depletion rate for the underground reservoir between Salinas Dam and the City of Paso Robles was estimated at 70 acre- feet per day in 1959 but may vary from year to year. The Board estimates that the summer water requirements of the users along that reach of the river are about 30 cfs. With fish and their River ecosystem having prior water rights to the Salinas River downstream of the Dam and users between the Dam and Paso Robles potentially having summer low flow season water rights to about 30 cfs, and with possibly at least some of these users having vested rights prior to the City's, it could be that the City has very little rights to the water being diverted from its existing Dam Project. This possibility which must soon be resolved by the SWRCB and others, could lead to the distinct possibility the City has no rights beyond some portion of the water it diverts from the existing Dam Project making the Proposed Subject Project moot. Beyond soon resolving this complex water rights issue, as I discussed in my 5/5/99 letter to the SWRCB, flow studies must also be soon initiated to determine adequate flows for the River with the existing Dam Project to keep fish as steelhead and all aquatic and terrestrial species reliant on the River ecosystem and the River ecosystem itself in good condition downstream of the Dam including in the ecologically important Salinas River Canyon. Whether the various experts and interested parties determine the Instream Flow Incremental Methodology (IFIM), as for in the steelhead suitable 14-mile Canyon stretch of the River, or some other flow study methodology as the 21 Montana Method, or whatever be used to make these adequate flow determinations, this process must start soon. In the meantime the SWRCB should issue an order prescribing the conditions at the end of CSPA representative Felix Smith's written testimony. And the SWRCB should further in consultation with CDFC, CSPA, NMFS, USFWS, and other interested parties issue an order or initiate in some other manner an interim process that will . establish temporay flow regimes far more conducive to the survival of fish, other aquatic and terrestrial species, and their Salinas River ecosystem habitat than the current inadequate LSA provides (a visible trickle), until the proper flow studies to determine adequate flows foE fishes' good condition can be done. D. Habitat Requirements for Steelhead in the Salinas River Canyon Relative to Flow Requirements: In both my 515/99 letter to you (CSPA "Exhibit DD") and my FEIR comment letter to you (CSPA "Exhibit FF"), I discussed habitat requirements for steelhead in the Canyon stretch of the River specifically and the River in general in relation to my knowledge as a fisheries biologist and in relation to the FEIR's APPENDIX L (comprised of APPENDICES L-1 and L-2) ADDITIONAL INFORMATION ON THE OCCURRENCE OF STEELHEAD BELOW THE DAM AND THE BIOLOGICAL CONSEQUENCES OF REDUCED SPILLS. In summary here of my discussions in those two letters I covered the historical background information from APPENDIX L and elsewhere establishing the excellence of the Salinas River for steelhead in the pre-Salinas Dam era. I also discussed based on jnformation in the same FEIR documents how that excellence has been diminished primarily by the construction of the Dam in 1941, to the point where it was reported in APPENDIX L-I that Nehlsen et. al. in 1991 concluded that the Salinas River steelhead was at moderate risk of extinction. And the steelhead may be at even higher risk of extinction now nearly a decade later. But based on my own knowledge and information in APPENDIX L, I also discussed in my two letters and will briefly add to it here that with adequate flows the 14-mile Canyon stretch of the Salinas River would be excellent steelhead habitat not just as upstream migration habitat to Canyon tributaries and downstream. adult and juvenile steelhead migration habitat to the Ocean, but also good spawning, nursing, and rearing habitat. I have already discussed herein that if adequate flows are provided (1) the two small private dams in the Canyon will not be a barrier to steelhead migration and (2) proper scouring and flushing will take place - to create good steelhead and other aquatic species stream system habitat (cut-banks, pools, riffles, runs, clean gravel and other bottom types, etc.) and to regenerate riparian forests on a continual basis. There was a small question raised in the EIR that at least some areas of the Canyon stretch of the River might not be conducive to steelhead survival. However, I answered this in my two letters by indicating that such. steelhead survival parameters as water temperature, riffles, and gravel conditions are not only adequate for steelhead survival in the Canyon stretch of the River now, but with adequate flows to keep fish in good 'condition such parameters in the� stretch of the ,� t` will be very conducive to adult steelhead Zz spawning, steelhead egg incubation and hatching, and juvenile steelhead rearing and migration downstream. I further discussed that my summertime water temperature measurements indicated temperatures well within the limits for steelhead summertime survival. And I provided three photographs (labelled 3, 4, and 5) in Exhibit I of my 5/5/99 letter to you (these photos are attached to my 6/2/98 FEIR comment letter which is also part of Exhibit 1 of my 5/5/99 letter) showing areas with good steelhead spawning, hatching and rearing gravels, riffles, and runs in the Canyon. For the�WRCB's review I have also provided you with more photos on Pages 4 and Pag of CSPA "Exhibit CC" showing good gravels, riffles, and runs for steelhead spawning, incubating/hatching, and rearing in the Canyon stretch of the Salinas River. The point in this part of my written testimony is that with adequate flow conditions in the River most of the 14-mile stretch of River in the Canyon will be excellent steelhead habitat. All of the necessary conditions except adequate flows exist in the Canyon for steelhead. Therefore, the SWRCB needs to require the City to do a SEIR to assess the heretofore unassessed significant and cumulatively significant adverse impacts of the Proposed Project on the Canyon riverine ecosystem including impacts on steelhead and other aquatic and terrestrial species including threatened and endangered species discussed elsewhere herein, and all of which rely on this River/riparian system. And the SWRCB needs to initiate by order or other means available to it flow studies that will lead to information to soon correct the serious environmental inadequacies of the LSA. And as previously discussed herein, the SWRCB needs to convene or help convene the necessary experts and interested parties to develope an interim flow regime much better than the LSA for keeping fish and other species and their River habitat in good condition, until the formal flow studies with recommended mitigations, alternatives, and conditions are completed, reviewed, modified if necessary, and implemented. V. Enviromental Impacts Upstream of Salinas Dam: In my IDEIR and RDEIR comment letters, which are part of the FEIR, I devoted more U t t� ev�erre and extensive significant adverse environmental impact at wo°Ould' occur from the Proposed Project. The primary reason for 7at s was because the City was overlooking then as now downstream impacts but sessing the upstream impacts that would primarily occur due to inundation caused by raising the Dam 19', it was relatively easy at that time to comment on the adequacy or inadequacy of their upstream EIR assessment. It took much longer for interested individuals and parties as myself to develope comments on the many unassessed downstream impacts, as in the Canyon, because we commenters had to do the environmental assessing and commenting dde to the City's negligence regarding downstream impacts. Negligence is a proper term because the LSA the City relies on solely for "mitigating" downstream adverse environmental impacts from past, present, and now proposed water diversions, is basically a dead fish agreement because fish cannot live in a visible trickle. And that visible trickle is all the LSA requires year round, except when the River is dry. Then the LSA requires Dam flow releases equivalent to the "dry flows" in the River upstream of the Reservoir. As I have had time to do more assessing of the EIR unassessed environmental impacts downstream of the Dam, I have been able to build a downstream environmental case against the City and its EIR, and have devoted considerably more time on downstream impacts in my 6/2/98 FEIR comment. letter, my 5/5/99 letter to the SWRCB to preserve the CSPA Protest, and this written testimony for the Oct. 12 SWRCB hearing. However this more recent greater emphasis on my part to the downstream impacts does not mean that I am any less concerned than I ever was regarding the upstream impacts of the Proposed Project. If anything I am more concerned than ever, as I have likewise had more time to assess in the field the devastating impacts this Proposed Project will have on the environment in the proposed inundation zone. Over 70 acres of wetland and . mature multi-canopied riparian forest on nearly 3 miles of creek and River will be lost. This type of nearly unharmed mature, valley, riverine riparian forest along a wide (up to 400 yards wide), braided unchannelized, undeveloped, stream channel is very rare in California, as over 200 major mountain valley and canyon bottom dams have wiped them out in so many places. And in other places where their remnants still exist, they have been channelized, developed along, and diked into vestiges of their past _ ecological beauty and grandeur. But here is a large intact riparian forest g �� worth saving every part of for its many aquatic and terrestrial species that use it. And it should be saved for people who need relatively unscathed examples of what was and what could be again in other areas. And the inundation zone will destroy about 2500 oaks of various species and about 470 grey pines. Many of the oaks are large and several hundred years old, and many of the pines are also tall and ol� There is also important wildlfe foraging grassland and oak savannah habitat scent to the upper Salinas River riparian forest and significant chaparral wildlife food and cover habitat around the lake in the Proposed Project inundation zone. In my 5/5/99 letter to the SWRCB, I provided color photos of some of the significant riparian, oak, and pine forest areas. These photos of the 2-mile long riparian forest along the upper Salinas River that will be destroyed by pUfSr inundation drowning are labelled 6 through 14 in Exhibit 1 (attached to my }) 6/2/99 FEIR comment letter which is also a part of Exhibit 1 of the 5/5/99 letter). And these same photos labelled 6, 7, 9, and 12 show some of the native fish inhabited braided upper Salinas River channel as well as the multi- storied/canopied mature willow riparian forest along the River that will be lost to inundation. And in Exhibit 2 of my 5/5/99 letter, color photo 5 shows the 400 yard—wide end of this up to 60' tall mature willow riparian forest where the current Salinas Reservoir high water line level has drowned and eliminated over time the same type of riparian forest that would have existed in the Reservoir area prior to construction of the Dam. This photo -also dramatically shows what will 32 be the drowning faight of the marvelous existing long and wide riparian forest if the Proposed Project is built. Color photo 6 shows a similar tall (over 60' high in places) mature riparian forest of about 3/4 mile iong on Alamo 2�f Creek which would likewise be destroyed by inundation drowning. And color photos 7 and 8 show some of the thousands of oaks and hundreds of gray pines 33, that would also be drowned around the edges of the Reservoir. To supplement these photos showing the unmitigable damage that will be done to these extensive mature habitats in the inundation zone around the Reservoir, I have provided you with more photos in CSPA "Exhibit CC". 3 rf Pages 6 and 7 show more of the mature riparian forest on the upper Salinas River and Alamo Creek that will. be drowned. And Pages 8 and 9 of "Exhibit CC" and CSPA "Exhibit Y" show more of the oaks and pines that will be destroyed by 35. drowning. In viewing and assessing this loss of ancient mature habitat it is almost incomprehensible that for the loss of mature multi-canopied riparian forest, ancient oak woodlands, and old tall pines, the City will likely end up planting seedlings. That is what the great new politically correct buzzword "restoration/enhancement" mitigation with all its developer and water diverter "mitigation" money is all about. But why not spend more effort trying to preserve and protect the works of nature with its ancient riparian, oak, and pine forests? But restore and enhance is what the City's inadequate mitigation plan is all about. This mitigation plan is proposed on pages 2-1 to 2-3 of the City's PROPOSAL Phase I of Services for Salinas Reservoir -Expansion Project (CSPA "Exhibit V). But in reading this plan one can see besides planting .many seedlings for the thousands of large, old oaks, willows, and fi9afieA� trees, the City plans to buy bits and pieces of habitat on many sites in and on places yet unknown. This is proposed to replace large intact oak, pine and riparian forests around the lake and along the Salinas River and Alamo and Toro creeks. The photos referred to above, as in CSPA Exhibits "CC" and "Y'� give some idea of the magnitude of these large unfragmented habitat areas so critical to native plant and wildlife survival. With such large unbroken habitat areas native fish, wildlife, and plants have a great measure of protection from within the vastness of the habitat. When this natural habitat is destroyed and proposed to be replaced by many smaller restoration and enhancemenfffMat environmental harm is done to these species and their existing natural unfragmented habitat areas. To give the SWRCB and others a better idea of the many ecological problems that result from breaking up large habitat areas, or equivalently as in the case of this Proposed Project by destroying large habitat areas and proposing to replace them with many smaller areas, I provided . an attachment to my 6/2/98 FEIR comment letter (CSPA "Exhibit FF") titled Biological Consequences of Ecosystem Fragmentation: A Review. Please read this Review because it sets the stage for what will replace large, unfragmented habitats that would be lost in the inundation zone due to the Proposed Project. Many small areas of restored and enhanced habitat areas are equivalent to habitat fragments when compared to these large unfragmented forested habitat areas that will be destroyed by the Proposed Project. And due to the many smaller areas far lesser ecological value than the large unfragmented areas, the former under any environmental/ecological measure cannot be construed as mitigation for the latter. As a final point on this issue, page 2-1 of CSPA "Exhibit X" indicates in .bullets two and three that 128 acres of riparian and marsh will be restored and 3 miles of 100-foot-wide stream corridor will be enhanced. But these areas will be found and enhanced and restored in multiple areas according to the City's mitigation Proposal, in order to come up with the acreages shown in these two bullets. But as discussed above, these many small areas are not near as ecologically valuable to wildlife as the large intact areas that now exist that are represented by the acreages of these two bullets. For example the 3 miles of 100-foot-wide stream corridor enhancement is not ecologically close to replacing the 3-miles of in many places several hundred yard wide braided stream and riparian habitat. And the millions of dollars the City has indicated in their mitigation Proposal (CSPA "Exhibit X") and various other associated EIR documents cannot buy or replace habitat anywhere close to equivalent to these large unfragmented forested habitats that this Proposed Project would destroy. And if the City wants to pursue this environmentally unreasonable project, then the SWRCB must require that the City does a SEIR, explain where all these bits and pieces of proposed fragmented habitat in their mitigation Proposal are going to be and to assess how these small habitat areas are going to ecologically replace the large unfragmented habitat areas this Proposed Project would destroy. This must be done honestly because up to now, neither in the certified FEIR nor in the City's post FEIR mitigation Proposal, has the City explained where all this mitigation is going to be and how it truthfully is going to replace what the Proposed Project would destroy. The point is the Proposed Project must not be built, for the loss of these large unfragmented riparian, oak, and pine forest habitats are unmitigable, as demonstrated by the City's Proposal (CSPA "Exhibit X") to replace them with many much smaller, ecologically unequivalent habitat areas. At some point society must say the environmental costs far outweigh they in comparison economic gains. And this is just such a project. The diversion of 17,949AFY to supply the City with only 1650AFY when compared to the downstream environmental impacts associated with more flow reductions, as impacts on threatened steelhead, and these enormous unmitigable losses of mature ancient oak, pine, and riparian forests is simply not a reasonable tradeoff for society as a whole and the many species we entrust ouselves with to protect. VI. Conclusion: In this written testimony I have given the environmental/ecological reasons and justifications for requesting that the SWRCB (1) require that the City do a Supplemental EIR for heretofore unassessed impacts upstream and downstream of the Dam, (2) initiate right away flow studies to determine and set into action ecologically adequate flows to replace the "Live Stream Agreement" in order to keep fish, as steelhead, and other species and their Salinas River/riparian habitat in good condition, (3) issue an interim order within 30 days of the hearing date requiring the permittees to release additional flows from the Salinas .Reservoir based on the evidence presented at this hearing, and (4) deny the City's request for an extension of time to complete construction of the Salinas Reservoir Expansion Project and the beneficial use of the unused portion of the water referred to in Permit 5882.

I-�endt�so•� San Luis Obispo, California 93401 Re: Salinas Reservoir Expansion Project Objection of Atascadero Mutual Water Company Dear Council Members: This law firm represents the Atascadero Mutual Water Company("AMWC"). On behalf of AMWC,we object to the proposed action to adopt a resolution(i) approving the Salinas Reservoir Expansion Project;(ii)adopting the California Environmental Quality Act findings;(iii)approving the Mitigation Monitoring and Reporting Plan(including Statement of Overriding Considerations); and(iv)directing City staff to file a Notice of Determination. The grounds for our objection are set forth below. Initially, it should be noted that the City Council is incapable of exercising its unbiased discretion in consideration of this matter if in fact it must either approve the proposed resolution and file a notice of determination by November 13, 2000 or forfeit the City's claimed right to an additional annual diversion of 1,650 acre feet of water. On or about October 19, 2000, the State Water Resources Control Board ("SWRCB') issued Order WR 2000-13 whereby the SWRCB approved the City's request for a time extension to complete beneficial use of water and construction of the Salinas Reservoir Expansion Proj ect on the express condition that the City approve the proj ect and filea notice of determination within 25 days after the issuance of Order WR 2000-13. If the . notice of determination is not filed within that time(November 13), the time extension is deemed denied. The SWRCB action apparently leaves the City.Council with no viable alternatives. They must approve the project or risk forever losing claimed water rights. Given this state of affairs, it is inconceivable that the City Council will be capable of exercising its discretion to perform an unbiased analysis of the project and the adequacy of current CEQA review. It is a foregone conclusion that the City Council will take the action necessary to secure the time extension as mandated by SWRCB. r City of San Luis Obispo November 9, 2000 Page 2 The City Council,under the present circumstances,cannot perform its duty to fully and fairly consider all issues before taking its actions. It is committed to one course of action and cannot reasonably be expected to veer from that course. Under analogous circumstances, the California Court of Appeal set aside the action of a local legislative body adopting a resolution of necessity because the agency hearing adopting the resolution was a "sham" and a merely "rubber stamped predetermined result." [Redevelopment Agency of the City of Huntington Park vs. Norm's Slauson (1986) 173 Cal. App 1121, 1127] We submit that the November 9 hearing is likewise a sham and that the City Council will merely "rubber stamp" a "predetermined result". If this happens, the decision in Redevelopment Agency vs.Norm's Slauson will require a court to ultimately set aside the City Council approval of the Salinas Reservoir Expansion Project.' The City Council's apparent inability to exercise its discretion is of particular concern because it must consider the adequacy of the final environmental impact report ("EIR") and the adoption of a statement of overriding considerations authorizing the project despite admitted Class I impacts. AMWC has previously submitted comments detailing the inadequacies of the draft and final EIR. Those comments are attached hereto and incorporated as part of the objection to the proposed action. Among the primary concerns is the failure of the EIR to conduct a meaningful analysis of the effect of the project on downstream recharge. Lacking that analysis,the EIR cannot possibly provide an adequate discussion of the physical impacts of the project. AMWC intends to present expert testimony at the November 9 hearing to more fully explain this issue. We are confident that this testimony would normally cause the City Council to find the EIR inadequate and require further analysis. It does not appear that such an action, although legally required, is an option the City Council will consider. Moreover,a serious environmental concern regarding seismic safety has been raised which requires further environmental review before the project can be approved. In fact,in its own staff report,the City admits that(i)a preliminary study conducted by Woodward-Clyde has determined that the dam,when expanded, "would not meet DSOD standards;" (ii) if the preliminary report is accurate a redesign of the project will be necessary before expansion; (iii)further investigation and analysis of the seismic issues is necessary; and (iv) "If future studies reveal that the dam must be strengthened, supplemental environmental review will likely be necessary..." Given these admissions by the City, it is clear that the City Council cannot approve the Project unless and until an adequate supplemental environmental impact report is prepared and adopted. The California Environmental Quality Act ("CEQA") requires the preparation of a supplement environmental impact report when either: 'Nothing in this letter should be construed as a challenge to the integrity or commitment of the San Luis Obispo City Council. Rather, it is our intention to point out the unfortunate circumstances that prevent the City Council from carrying out its legal obligation to fully and fairly consider the issues before it. City of San Luis Obispo November 9, 2000 Page 3 (1) new information,which was not known and could not have been known at the time the environmental impact report was certified as complete information becomes available. (2) substantial changes occur with respect to the circumstances under which the project is being undertaken which will require major revisions in the environmental impact report; or (3) substantial changes are proposed in the project which will require major revisions of the EIR. (Public Resources Code Section 21166 and CEQA Guidelines 15162) The October 20, 2000 letter from counsel for the City of Paso Robles to the City Council provides an excellent analysis of the necessity for a supplemental EIR based upon the Woodward Clyde seismic report. We incorporate that letter into our objection to the project. .Further,the City's approval ofthe Project must,of necessity,include further seismic analysis which will likely have a material impact on the design of the project. The project to be approved is simply not safe. This reliance on future studies to both design and to mitigate the Project impacts is a direct violation of CEQA. [Sundstrom v. County of Mendocino (1988) 202 Cal. App. 3d 296; Oro Fino Gold Mining Corp. v. County of El Dorado (1990)225 Cal.App.3d 872, 884-885.] The seismic study must be completed and evaluated as part of the EIR prior to Project approvaL It is clear that the City is not in a position to approve this Project unless and until further environmental analysis is performed. It is equally clear that,despite these statutory deficiencies,the City Council will almost certainly approve the Project in order to avoid the possible loss of its time extension. We urge the City Council to follow the law and consider the approval of the Project only after full, complete and meaningful environmental review.

The following are AMWC's comments to the discussion of potential downstream flow reductions in the Revised Draft Environmental Impact Report for the Proposed Salinas Reservoir Expansion Project dated May 1997 ("Revised Draft EIR'). AMWC reserves the right to supplement, withdraw, or limit any of the comments set forth in this letter. Initially, we reiterate that AMWC remains committed to full development and utilization of all water available to the County of San Luis Obispo for its highest and best use. Its highest priority, however,remains the protection of the rights of its water users to a constant and adequate water supply consistent with the full set of water rights held by AMWC. As set forth in more detail herein, the discussion of potential downstream flow reductions contained in the Revised Draft EIR is seriously deficient in several respects including the following: (a) it fails to accurately define the subject Project and its purpose; (b) it fails to adequately consider project alternatives; (c)it fails to adequately identify or analyze possible mitigation measures;and(d) it fails to accurately and objectively identify and analyze potential downstream impacts. CEQA requires that the City conduct an unbiased and impartial review of these issues. CEQA requires a public agency to deny or limit approval of a project with significant adverse effects when feasible alternatives or mitigation measures can substantially lessen such effects. To do so,the public agency must assure itself that the information contained in its review process is objective and unbiased. Unfortunately,it appears that the analysis of the alternatives,mitigation measures and impacts contained in the review was intentionally slanted to provide the desired result, e.g., no feasible alternative, no feasible mitigation measure and no significant impact As such, information and Mr. Glen Matteson July 24, 1997 Page 2 analysis critical to understanding the full impact of this project is not included in the Revised Draft EIR The City has repeatedly stated its desire to work with North County residents to address their concerns and to develop water resources cooperatively. Certification of the Revised Draft EIR in its current form would directly contradict this stated desire. 1. Atascadero Mutual Water Company. AMWC is a private company which provides water to its shareholders residing in and around the City of Atascadero. AMWC's existence dates back to 1913,when Edward Lewis purchased the 23,000 acre Henry Ranch which eventually became the Colony of Atascadero. In 1914, Lewis transferred all of the Henry Ranch's then existing water rights—including appropriative, riparian and overlying—to AMWC,a newly formed mutual water company. Water supplied by AMWC is used for residential and commercial uses including government, schools and hospitals within its service area Presently,AMWC provides water to over 25,000 North County residents. AMWC depends entirely upon shallow and deep ground water resources in the vicinity of the Salinas River to supply its customers. Atascadero is located in the Atascadero Sub-basin which is particularly dependent on recharge from the Salinas River,rather than being in the larger Paso Robles ground water basin which is influenced by recharge from other main tributaries. Prior to 1970, AMWC's sole source of water was the Salinas River. Currently, AMWC operates 7 wells ("shallow wells')which draw water from the underflow of the Salinas River. Since 1970,AMWC has also relied on groundwater withdrawn from the Atascadero Sub-basin to supylement its water supply. Currently, AMWC operates 7 wells ("deep wells') which draw water from the Atascadero Sub-basin. AMWC holds at least three forms of water rights related to the Salinas River. First,as a result of the 1914 transfer noted above,it holds on behalf of its shareholders a riparian right to the beneficial use of water from the Salinas River on lands within its service area Second, it holds pre-1914 appropriative rights to a portion of the Salinas River. Third, it has license to appropriate at least 3372 acre feet a year from the Salinas River. This last appropriation has a priority date of January 13, 1916. AMWC currently has no significant source of water other than the Salinas River and the Atascadero Sub-Basin. 2. Initial Draft EIR. The initial Draft EIR was released in November 1993. AMWC submitted written comments in a letter dated January 3, 1994,a copy of which is attached hereto as Exhibit"A". AMWC criticized Mr. Glen Matteson July 24, 1997 Page 3 the initial Draft EIR because it: (1) failed to analyze the impact of stream flow reductions from the dam to Paso Robles; (2) failed to discuss or analyze the potential effect of reduced stream flows on downstream riparian rights;(3) failed to identify and address all feasible mitigation measures;and(4) failed to consider all project alternatives. AMWC incorporates by reference the comments contained in Exhibit A as applicable and responsive to the Revised Draft EIR. Additional comments were submitted in a letter dated March 11, 1994, a copy of which is attached hereto as Exhibit"B". AMWC noted in this letter that the proposed expansion project could impact the recharge of downstream shallow and deep aquifers by reducing the "scouring" of stream sediments during strong flows and by decreasing the amount of time that there is"high water"within the recharge areas along the Salinas River corridor. AMWC incorporates by reference the comments contained in Exhibit B as applicable and responsive to the Revised Draft EIR AMWC also solicited comments from three hydrologists: (1)Tim Cleath,(2) Rick Hoffman; and (3) Donald Weaver. Written comments received from each of these gentlemen were forwarded to the City. Attached hereto as Exhibit"C"and"D"respectively are Mr. Cleath's letters of December 31, 1993 and February 9, 1994 discussing some of his concerns related to the project. Attached as Exhibit"E" is Mr. Hoffman's letter of February 8, 1994 addressing some of his concerns. Attached as Exhibit"F" is Mr. Weaver's letter of February 9, 1994 addressing some of his concerns. AMWC incorporates by reference the comments contained in these letters as applicable and responsive to the Revised Draft EIR- On May 2, 1994, the City—through its attorney Scott Slater—provided AMWC with a written response to its March 11, 1994 letter. A copy of this letter is attached as Exhibit"G". Mr. Slater stated that the City would address AMWC's concerns "in detail in its final EIR." In fact,no final EIR was issued. Mr. Slater stated,without any support,that"scouring effects from flood flows would be insignificant in terms of recharge to the groundwater basin"' As to flow reductions,Mr.Slater stated— again without support—that "a reduction in the duration of high water conditions will have no significant effect on recharge so long as the Live Stream Agreement is in effect......2 Thereafter, the City decided to withdraw the initial Draft EIR. AMWC made available all of its records relating to the Salinas River, including all daily and monthly data it had on its shallow and deep wells.AMWC personnel have also been available to the City. 'As discussed herein,the Revised Draft EIR fails to consider or analyze whether the expansion would retard the scouring effect identified in the March 11, 1994 letter. 2 A discussed herein, the Revised Draft EIR states that a higher flow(e.g., more than just a "live stream')will result in faster recharge of the underground aquifers. Revised Draft EK p. 34-23. Mr.Glen Matteson July 24, 1997 Page 4 3. Revised Draft EIR AMWC has again asked Mr. Cleath to comment on the analysis contained in the Revised Draft EIR. Some of Mr. Cleath's initial comments on the Revised Draft EIR are contained in his letter of July 17, 1997, a copy of which is attached hereto as Exhibit"H". AMWC incorporates by reference the comments contained in these letters as applicable and responsive to the Revised Draft EIR- Additional IRAdditional comments are set forth below. a. Inadequate Project Description. The Revised Draft EIR defines the project as the expansion of the Salinas Reservoir. Atone point, the Revised Draft EIR defines the `purpose" of the Project as securing "additional water supplies to help meet the City's projected water demand deficit. Elsewhere,however,it defines the purpose more narrowly as providing the City with 1650 AFY of additional water supplies on a safe annual basis. The failure to clearly and properly define the project and its purpose violates CEQA. The difference between these two Project definitions is critical. If the purpose is defined as securing additional water to meet a future estimated shortfall, it would obviously be incumbent on the City to identify and analyze known alternative sources for such water. However, by narrowly (and incorrectly)defining the purpose of the project as providing the City with 1650 AFY—and no less—from only one source,the City avoids the responsibility of engaging in such an analysis. Proper definition of the project and its purpose is critical to complying with CEQA. As one court has stated,"Responsibility for a project cannot be avoided by limiting the title or description of a project." Rural Land Owners Assoc. v. Lodi City Council (3rd Dis. 1983) 143 Cal.App.3d 1012, 1025. Here, the only proper description is securing additional water to meet the City's projected firture need. This is consistent with the City's General Plan which requires that-the City obtain additional water from multiple sources. The qualifier that the project being studied must secure 1650 AFY is not supported by the General Plan,masks the real purpose of the project and prevents a full,fair and objective consideration of the resulting environmental impacts. How the project and its purpose are defined is even more critical in light of the City's recent downward revision of its projected water needs. At the time of the initial Draft EIR, the City projected it needed 6265 AFY more a year by the year 2015. Since that time,the City has concluded that it needs only 3861 AFY more by the year 2022. This substantial reduction in projected need makes it even more likely that some combination of sources other than the dam expansion(or in conjunction with a modified expansion) could be readily utilized to fully satisfy the City's needs. The Revised Draft EIR acknowledges that the Naciemento Project alone could fully satisfy all of its needs. Selection of a source or set of sources other than the described Project would obviously have dramatically different environmental impacts. It is quite likely that a set of sources could be Mr. Glen Matteson July 24, 1997 Page 5 developed at less expense and with fewer detrimental impacts. However,because the Revised Draft EIR incorrectly defines the Project,no information is provided with which the City and the public can rely on to make a proper decision. The Revised Draft EIR needs to be rewritten to clearly state that the purpose of the Project is to increase the City's future water supply. b. Failure to Adequately Consider Alternatives. Under CEQA, the required discussion of alternatives must focus on alternatives which are "capable of avoiding or substantially lessening any significant effects of the project, even if these alternatives would impede to some degree the attainment of the project objectives,or would be more costly." CEQA Guidelines, Section 15126(d)(1). The EIR must ensure that all reasonable alternatives are thoroughly assessed by the responsible parties. At the time of the initial draft EIR,the City projected a water supply deficit of 6265 AFY by the year 2015. This included a 2000 AFY reliability reserve. The proposed project would provide approximately 1650 AFY of additional water or about 25 %of this projected deficit. The initial Draft EIR did not consider the following projects as alternatives because they were already being pursued by the City to"help"offset this projected deficit The projects not considered include:Naciemento-Reservoir Water Supply Project;groundwater increased wastewater reclamation; continued conservation; and periodic cloud seeding. The only alternatives actually considered were Seawater Desalination and Transfers from the Salinas Reservoir to the Whale Rock Reservoir. Since the initial Draft EIR,the City revised downward its projected need for additional water. As noted in the Revised Draft EIR, the City now concludes it needs only an additional 3,861_AFY (including the 2000 AFY reserve)by the year 2022. Despite this substantial reduction,the Revised Draft EIR refiises to consider as possible alternatives (either separately or conjunctively):groundwater, wastewater reclamation, continued conservation or cloud seeding. The Revised Draft EIR does note that all of the City's projected deficit could be satisfied by the Naciemento Reservoir Water Supply Project Further, the Revised Draft EIR notes that the dam expansion will not be needed if the Naciemento Project proceeds. Despite this conclusion, the Revised Draft EIR fails to adequately analyze or consider the Naciemento Water Supply Project—individually or in conjunction with other possible sources—as a possible alterative project Instead,it notes that the feasibility of the Naciemento project is"currently still being assessed...." According to the Revised Draft EIR,the findings in the forthcoming EIR on the Naciemento project will be "considered in the Final EIR.for the Salinas Reservoir Expansion Project" Mr. Glen Matteson July 24, 1997 Page 6 It is impossible to assess and comment on the potential environmental impacts of the expansion project without at least an initial assessment of the Naciemento project Naciemento water may fully meet the projected needs of the City. Alternatively, imported Naciemento"water could be used to partially or filly mitigate any potential reduction in downstream flows caused by the expansion project Importation of such water may also have an impact on operation of the Live Stream Agreement Further,effected entities may be able to"trade"water held back by the Salinas dam for Naciemento water. The Revised Draft EIR should also not remove from consideration other potential sources of water, merely because the City is already pursuing or counting on these sources to offset the alleged future deficit. This is particularly true in light of the fact that the City's projected deficit has been substantially reduced. In essence, the City had defined the project goal as development of a single source of 1650 AFY. This is simply not proper,particularly in light of the City's recent reduction of its projected deficit and the substantial time remaining before this deficit becomes an issue. The EIR should address how much water these other projects might produce. The EIR should also address whether these projects can be combined with Naciemento or a reduced dam expansion (e.g.,a smaller set of gates)to provide the City with the water it believes it needs. Finally, the Revised Draft EIR makes no mention of State Water as a possible alternative in conjunction with one or more of the above mentioned sources. AMWC understands that the County and other governmental entities are willing to sell or transfer excess State Water. The Revised Draft EIR should consider this possible alternative. AMWC and others believe that all these potential alternatives need to be planned and studied together to effect the"greatest good"including mm' h' n .ing environmental impacts. However,the City is effectively stifling both effective analysis and public comment by refusing to discuss these alternatives—separately or conjunctively—in any meaningful manner. These defects are particularly inexplicable in light of the recent substantial reduction in the projected deficit AMWC requests that the City produce a new draft EIR which filly addresses all of the relevant sources of water available to the City. At a minimum,the City should allow further comment on the Revised Draft EIR once the Naciemento EIR is circulated. c. Failure to identify and discuss reasonable mitigation measures. For purposes of CEQA,the proposed project is the expansion of the Salinas Dam. The purpose of the expansion is to increase the City's supply of water. It is not proper under CEQA to narrowly define the project as the expansion of the dam and acquisition of 1650 AFY and then reject out-of- hand any mitigation that might limit the City's ability to fully reach this goal every year. Unfortunately, this is precisely what both the initial Draft EIR and the Revised Draft EIR conclude that "downstream flow-related effects are not considered to be feasibly mitigable since Mr. Glen Matteson July 24, 1997 Page 7 releasing more water downstream would not allow the project's goals to be met" This reasoning, which rejects out-of-hand anything less than fall build out and operation in accordance with the project definition, falls far short of the analysis required by CEQA. Moreover, it assumes, without analysis, that any conceivable mitigating measure would: (1) require a release of water and (2) would prevent the City from obtaining an additional 1650 AFY every year. The EIR should fully analyze and discuss all potential mitigation measures. Possible mitigation measures include: (a) allowance of periodic "flood stage" runoff cycles; (b) controlled releases timed to offset adverse impacts; (c) construction of an emergency flow water pipeline; (d) storage of only a portion of the maximum stream flows in any one year,(e)conjunctive use of the dam and the Naciemento Project waters; (f) conjunctive use of dam and other sources (including those identified herein); and (g) strengthening the enforcement mechanism contained in the Live Stream Agreement. d. Failure to Adequately Identify and Assess Downstream Impacts. 1. Downstream Flows. The Revised Draft EIR attempts to set forth the impact of the project on downstream flows. The analysis is flawed for several reasons including the following: _ a) 10.000 AFY Assumption. The Revised Draft EIR uses a yield value of 10,000 AFY for both its existing and raised dam scenarios. It is not reasonable to assume the City will withdraw the same amount of water in both scenarios. The reservoir's current safe annual yield is estimated at 4,800 acre-feet The spreadsheet calculation assumes the City would knowingly overdraft the reservoir at a greater rate under existing condition than under the raised dam conditions. This effectively changes the operational management of the dam between the two scenarios. Moreover,the existing facilities cannot physically convey 10,000 AFY. b) Results Reported Annually. The spreadsheet model results are reported on an annual basis. Both the spreadsheet and data sets are available on a monthly basis. Reduced flows on water supply include both long-term and short-term impacts. Averaging such impacts annually does not address short-term impacts. At a minimum,the Revised Draft EIR should perform a monthly analysis of those periods identified as having the greatest potentially significant impacts(e.g., 1992-1994). c) Methodology Used to Calculate Flow. The Revised Draft EIR relied entirely on a methodology adopted by the Morro Group to estimate the flow at Atascadero. Mr. Cleath has concluded that the estimates resulting from the Morro Group's analysis are questionable. He believes more accurate estimates of flow can be made by relying on information not available or not used by the Morro Group, including reservoir inflow data and gaged records for Santa Margarita Creek,Trout Creek and Yerba Buena Creek. Mr. Glen Matteson July 24, 1997 Page 8 d) Methodology Used to Calculate Decrease in Flow. The spreadsheet concludes that the proposed project would result in an average decrease in downstream .flow("Average Project Impact')at the base of the dam of 6.45%, 3.52%at Atascadero and 1.24% at Paso Robles. For any one year,the Project Impact(%)was calculated by dividing the Project Impact (AF) by the Historic Flow Below Dam(AF). However,to obtain these Average Project Impacts, the Revised Draft EIR averages the column of annual impacts rather than divide the Average Project Impact(AF)by the Average Historic Flow Below Dam(AF). Using a consistent methodology would result in average decrease in downstream flow of 11.2% at the base of the dam, 6.6% at Atascadero and 2.6%at Paso Robles. e) Carry-over Impact. As with well levels, discussed infi-a. the Revised Draft EIR makes no effort to analyze whether a reduced flow in one year will have a"carry- over"effect in any of the following years. f) Margin of Error. As with well levels, discussed infra, the Revised Draft EIR fails to state whether any of the estimated flows are subject to a meaningful margin of error. 2. Impact on Well Levels. The last step performed in the impacts assessment for water resources was a calculation of the estimated amount of water level decline in two AMWC water supply wells. The Revised Draft EIR does not analyze impacts below Atascadero because it concludes that the impact on these two wells is "minimal." Thus, it is critical to the report that the impact in the Atascadero area is accurately assessed. Unfortunately,it was not a) Well No. 1 is Atypical. The Revised Draft EIR assumes AMWC's Well No. I is a typical shallow well for purposes of analyzing shallow well level impacts. In fact, Well No. 1 is downstream from AMWC's other shallow wells and only 150 feet from Atascadero Creek. Historically, Atascadero Creek has a surface flow before the Salinas River and Well No. 1 reacts to that flow. b) Well No. 7. Well No. 7 is assumed to be a typical deep well. However, it is below the confluence of the Atascadero Creek. Moreover, no explanation is given as to why this well is deemed "typical." The EIR consultants were given all AMWC well logs to evaluate. The Revised Draft EIR should explain why Well No. 7 is the best deep well to analyze. c) Use of Annual Avemges.The Depth to Water figures provided for both wells are annual averages. Timing of water flows, demand and supplies are critical to AMWC. Of particular importance to.AMWC is monthly and seasonal variations in well levels. Annual averages simply do not address these issues. In fact, they may mask a serious monthly or seasonal impact. In order to evaluate a worst case scenario, it is essential that monthly, or at least seasonal variations,be evaluated. Mr.Glen Matteson July 24, 1997 Page 9 The City should have sufficient data to make such an analysis. AMWC has kept detailed historical records on such variations. All of this data was made available to the City's consultants. d) Cann-over Impacts.No effort is made to ascertain the carry-over impact of the proposed expansion on water levels. Unanswered is how long an adverse impact in one year will cant'over into future months,seasons or years. e) Adjustments for Changes in Use.The Revised Draft EIR relies entirely on historical data to ascertain impact No adjustments are made for possible changes in the future concerning water use, population growth and other developments that may effect demands on the Salinas River downstream of the dam. f) Worst Case Scenario. The review claims that the maximum impact estimates are based on a worst case scenario in 1993, following many years of drought It would appear, however, that the maximum impact on downstream users would more likely be a relatively high flow year such as 1993 between several low flow years. In this scenario, downstream users may not be able to take advantage in subsequent low flow years of the carryover of a high flow year like 1993. As to establishing the historical worst case scenario, the initial Draft EIR discussed flows back to the mid40's. The Revised Draft EIR analysis stops in 1972. In ascertaining worst case scenarios for purpose of waxer use,most recent studies have gone back to the 30's or even earlier. The EIR should review all available historical data to determine if 1993 actually presents the historical worst case scenario. g) Impact not Actually Analyzed. No effort is made to correlate the estimated drop in well levels to actualproduction by AMWC. No effort is made to calculate impact on production,time of production or cost of production. For example,no consideration is given to the fact that several of AMWC's shallow wells have only 5 to 6 feet of perforated production and that they are the first to be tumed off when water levels are low. h) Scouting Effect High flows "scour" the riverbed enhancing percolation. In comments to the prior Draft EIR,AMWC asked that the City analyze what impact the expansion would have on this phenomena. The Revised Draft EIR fails to address this issue. i) Margin of Error. The Revised Draft EIR fails to fully explain whether any of the estimated well levels are subject to a significant margin of en-or. See also the comments contained in the Tim Cleath's letter of July 17, 1997. 3. Water Rights. The Revised Draft EIR fails to accurately,completely and impartially discuss the water rights held by downstream water users. There is no discussion of riparian rights held by actual and potential Mr. Glen Matteson July 24, 1997 Page 10 downstream water users,'including AMWC. There is no recognition given to the fact that whatever water rights the City may hold are inferior to earlier pre-1914 and appropriative rights, riparian rights and overlying rights. There is no discussion of possible challenges to the City's water rights. The City has never used the Rill amount of its appropriation raising at least the possibility that its right to increased storage has been waived or abandoned. The Revised Draft EIR assumes without discussion that neither the State nor an effected party will seek to have the Live Stream Agreement modified. The City is required to release from the reservoir an amount of water necessary to meet the rights of all entities with prior vested rights. "Until Rather ordered"it is assumed that"Live Stream"discharges meet this obligation. However, increasing use of downstream prior rights combined with the proposed expansion, may call in to question the validity of this assumption. The Revised Draft EIR states that requiring any discharge beyond that necessary to a live stream will defeat the purpose of the project. In that case, the Revised Draft EIR should discuss the possibility that the Live Stream Agreement may be altered in the future to protect the rights of existing and potential downstream users. See Comments contained in Donald Weaver's letter of February 9, 1994 attached hereto. Even if the Live Stream Agreement is not altered, it is likely that increasing demands will be placed on the Salinas River by downstream users. Such an increase may come as a result of a variety of factors. One would be increased population. Another would be more intensive use of water for agriculture. Increased flows may also be required to accommodate unforeseen environmental issues. The realistic possibility of increased use also calls into question the viability of the project. As noted, the Revised Drift EIR states that requiring any additional discharge for mitigation would defeat the whole project. As such, the City must analyze whether additional discharges reasonably called for by the Live Stream Agreement will also,defeat the project 4. Flood Risk. As to the potential risk of flooding from dam or gate failure, AMWC notes that the project assumes the dam will be transferred from the Federal Government to the County of San Luis Obispo. Whatever the risk of flooding,if flooding does occur,the County or some as of yet undefined portion of the County will bear the risk rather than the federal government The Revised Draft EIR should address the financial ability of the County or this portion of the County to repair any damage resulting from possible flooding. AMWC remains willing to work with the City and its consultants to provide a full analysis of the project's potential impacts, alternatives and mitigation measures. These issues must be fully considered to ensure that the City makes an informed decision and that the public is aware of the pros and cons on which they base any decision. As presently drafted, the Revised Draft EIR does not Mr. Glen Matteson July 24, 1997 Page 11 provide the City with acciirate, objective information. AMWC requests that the City's consultants revise the EIR to address the concerns set forth in this letter.

We were assisted in our review of the DEIR by Timothy S. Cleath of Cleath and Associates. Based upon our review, we have the following comments: General Comments Our primary concern in reviewing. the DEIR was the inevitable reduction in downstream flows along the Salinas River and the potential impacts of that reduction on the environment and those holding downstream water rights. The DEIR fails to address the potential impacts on that portion of the Salinas River between Salinas Reservoir and the City of Paso Robles. Rather, the limited analysis of the DEIR focuses on impacts beginning at the City of Paso Robles and beyond. Based upon the assumption in the DEIR that the impact of flow reduction is directly related to the distance of the measurement point from the Dam, it is imperative that the DEIR measure and analyze the impact of stream flow reductions on those points nearest the Dam. The DEIR, in failing to provide this measurement and analysis, falls short of discussing all relevant information and environmental impacts as required by the California Environmental Quality Act ("CEQA"). EXHIBIT A City of San Luis Obispo January 3, 1994 Page 2 AMWC is particularly interested in an accurate and complete analysis of the reduction in downstream flows because it depends upon shallow and deep ground water resources in the vicinity of the Salinas River for its supply. Those aquifers depend on recharge from the Salinas River to replenish ground water in storage, which is-ultimately used by AMWC. Atascadero is located in the western portion of the Paso Robles ground water basin, identified as "Atascadero Sub-Basin" in the Morro Group's 1991 report, "Long Term Viability of Water Supply, City of Atascadero", which is particularly dependent on recharge from the Salinas River, rather than being in the broader portion of the basin between Paso Robles and Shandon, which is influenced by recharge from other main tributaries (the Estrella and Huerhuero Creek systems). The Atascadero portion of the ground water basin refills from recharge during most wet seasons (The Morro Group report). Any reduction of flow which would otherwise contribute to recharge in the vicinity of the AMWC wells, must be evaluated and determined to be significant or insignificant. The DEIR is also inadequate because it fails to consider and discuss the potential effect of the reduction in flows on downstream riparian rights and how the environmental impacts resulting from any effect on the riparian rights. For example, if significant riparian rights are -effected, will those users seek to offset the loss by increased ground water withdrawals or will loss of riparian water rights result in a change in current land use for affected riparian lands? The DEIR must consider these issues in order to fully evaluate all impacts of the project.. The DEIR also fails to adequately address all feasible mitigation measures. In particular, the use of the increased storage capacity to provide water releases over and above those required by the Live Stream Agreement should be considered as a potential mitigation measure. The DEIR, however, provides no analysis of this potential mitigation measure. The reason given for this failure to provide analysis is that it would defeat the goals of the project. This reasoning, which rejects out-of-hand anything less than full buildout in accordance with the project definition, falls far short of the analysis required by CEQA. This potential.mitigation measure should be fully analyzed and discussed in the DEIR. Finally, the DEIR rejects the state water project as an alternative because the City's electorate has voted to forego participation. Failing to consider a project alternative merely because the project proponent does not prefer the alternative violates the analysis required by CEQA. All viable project alternatives must be considered regardless of whether or not they are preferred by the proponent. Even assuming that the City is precluded from contracting for water directly with the State, which is not established in the DEIR, it may be able to indirectly acquire water through contracting parties. City of San Luis Obispo January 3, 1994 Page 3 Specific Comments PAGE PARAGRAPH COMMENT ES-5 1 a) Reduced flow percentages at Atascadero should be estimated based on stream flow estimates in previous reports (The Morro Group, 1991). As noted in the general comments, the reduced annual flow percentage is probably much higher at Atascadero than the downstream localities cited. b) The DEIR should assess the incremental effect of the project assuming existing "cumulative effects". If the project increases the potential for an overdraft of the ground water basin, then this should be considered a significant impact. 3-78 3 This stream flow simulation should evaluate the impacts at Atascadero. See The Morro Group, 1991 for estimated historic annual stream flow totals for Atascadero. 3-88 2 The maximum incremental annual flow reduction at Atascadero should be estimated. 3-88 3 The peak monthly flow reduction at Atascadero should be estimated. The monthly flow reduction estimates are pertinent to the impact of the proposed project on water recharge. 3-90 2 This paragraph Purports to comprise the entire analysis of ground water recharge impacts but does not address the potential impact that reducing stream flow would have on ground water recharge in Atascadero. This should be addressed. 3-94 2 Mitigation measures directly related to the impacts of the proposed project on AMWC sources should be identified and discussed. City of San Luis Obispo January 3, 1994 Page 4 PAGE PARAGRAPH COMMENT 3-95 1 The conclusion that "impacts related to reduced ground water recharge are not expected to be significant" should not be made unless an analysis of the impact on the Atascadero area is performed and the conclusion is consistent with that analysis. 3-240 5 The cumulative impact of the project related to the incremental reduction in ground water recharge.resulting from this project is not discussed in this section despite the fact that this cumulative impact is referenced in other sections of the DEIR. 5-1&2 5&1 The discussion of reduced downstream flow should include those areas that exhibit the greatest reduced downstream flow (e.g., downstream of the dam to Atascadero). See the comment above regarding the inadequacy of the "cumulative effects" discussion of the DE1R AMWC is available to discuss these commentswith the City or a representative of Woodward-Clyde or to provide additional information or clarification.

Our earlier letter was based on a limited opportunity to review the potential geological/hydrological impacts of the project. We have subsequently retained expert consultants to further analyze the potential impacts. The preliminary conclusions of that analysis, which for the most part is an elaboration of our previous comments, are set forth below. Initially, however, we reiterate .the AMWC remains committed to hill development and utilization of all water in the County for its highest and best use. Its highest priority, however, is the protection of the rights of customers to a constant and adequate water supply consistent with water rights held by the AMWC. The DEIR needs to focus on the possible hydrologic impact of drought conditions on the recharge of Salinas River(shallow aquifer) and Atascadero sub-basin of the Paso Robles Groundwater Basin (deep aquifer). AMWC relies on recharge of the shallow aquifer and the deep aquifer to supply its customers. The Salinas Reservoir Expansion Project potentially impacts the recharge of the shallow and deep aquifers by reducing the scouring effect of stream sediments during floods and by decreasing the amount of time that there is "high water" within the recharge area along the Salinas River corridor. EXHIBIT $ City of San Luis Obispo March 11, 1994 Page 2 Total recharge depends on, among other things, the amount of water within the creek, its depth, the width of the creek, sediment particle size, and length of time the creek flows. The scouring effect of flood waters is vital to recharge of the aquifers because it removes fine grained sediments which collect on the creek bottom during normal low flow periods. The increase in water flow velocity during flood. periods exposes coarse grained sediments which have greater permeability and therefore allow more water to seep into the aquifers. The Salinas Reservoir currently spills over the dam about every two years. Expansion of the reservoir will cause a reduction in the peak monthly flow at Paso Robles gauging station of about 18 percent. This potentially reduces the scouring effect and the amount of recharge percolating to the aquifers. The reduction in frequency of dam overflow and peak monthly flows could also decrease recharge by decreasing the width, depth and duration of water flow: The increased capacity of the Salinas Reservoir may reduce the duration of high water conditions and resulting recharge to the aquifers. The maintenance of a "base flow" under the terms of the "live stream agreement" may not allow for the same amount of recharge to the aquifers as the high water conditions. In other words, reliance on the live stream agreement as the major mitigation factor, without a full analysis of the potential impacts of the expansion or aquifer recharge, is inadequate. The effect of Salinas Reservoir expansion on the supply of water for AMWC could possibly be mitigated by modifications to the "live stream agreement" or other agreements ensuring an ample water supply for AMWC during drought years. In any event, we believe that further analysis of the proposed project's effects on runoff conditions and the resulting recharge of aquifers must be conducted. As noted in my letter of January 3, the AMWC is willing to work with the City and its consultants to provide a full analysis of potential impacts. These impacts must be considered to ensure that the City Council makes an informed decision and that the public is aware of the pros and cons on which that decision is based.

Your main direction to me is to comment on whether or not the EIR consultant has adequately considered impacts to water supply sources on which the Atascadero Mutual Water Company depends. Atascadero Mutual Water Company depends upon shallow and deep ground water resources in the vicinity of the .Salinas River to supply its customers. Both the shallow and deep aquifers depend on recharge from the Salinas River to replenish ground water in storage, which is ultimately used by Atascadero MWC. Atascadero is located in the western portion of the Paso Robles ground water basin which is particularly dependent on recharge from the Salinas River, rather than being in the broader portion of the basin between Paso Robles and Shandon, which is influenced by recharge from other main tributaries (the Estrella and Huerhuero Creek systems) . The Atascadero portion of the- ground water basin refills from recharge during most wet seasons (The Morro Group, 1991) . With. these sources of water being recharged .by the Salinas River,. any reduction of flow which would otherwise contribute to recharge in the vicinity of the Atascadero MWC wells should be estimated and deemed a significant or insignificant impact. If significant, mitigation measures should be considered. I have identified several portions of the EIR which may need to be modified to address this issue.

Box 31 San Luis Obispo, CA 93406 SUBJECT: Potential Impact Considerations of Raising Salinas Reservoir Dam on Atascadero Mutual Water Company Water Sources Dear Mr. Adamski: Our main concern related to the Atascadero MWC water supply sources and the raising of the Salinas Reservoir continues to be that the EIR consultant needs to evaluate worst case conditions and not just historic records. It is these conditions which I will describe below: ASSIII4PTIONS Assume that there have been drought conditions for a couple of years and the reservoir is at the current capacity (the City having to use the Nacimiento water first and then using Whale Rock water, preferentially over Salinas Reservoir water) . Assume that there has been little water flowing into the reservoir for the prior few years, therefore resulting in less than live stream conditions downstream. Assume that, for the current year, there is only adequate runoff to fill a portion of the increased reservoir capacity, perhaps occurring during one storm, (while maintaining the minimum releases for live stream conditions downstream) . RESULTING CONDITIONS Under these conditions, ground water in storage would most likely be at low levels and that some of the water which could have recharged under existing conditions would be held in storage at the Salinas Reservoir. Runoff from the watershed area upstream of Atascadero but downstream, or adjacent to, the watershed area behind Salinas River Dam (which is roughly equivalent in area) should allow recharge of the Atascadero ground water supplies to some extent under these conditions but we would like to know if there will be sufficient recharge-under these conditions to maintain adequate resources for Atascadero MWC. ..\.KWC.LTft EXHIBIT 1 ) 1 February 9, 994 These conditions, if simulated, should be assessed on a monthly time step, showing shallow aquifer and deep aquifer ground water levels and stream flow amounts.

The purpose of the proposed Reservoir Expansion project Is to expand the capacity of the Salinas Reservoir by installing an operable gate within the spillway to effectively raise the level dam to capture and store more runoff water within the reservoir. The maximum storage capacity . will reportedly Increase from approximately 23,843 acre feet (AF) to 41,792 AF (page ES-1 within the EIR)., .The EIR concludes that the average annual incremental project related reduction in downstream flow relative to historical flow Is approximately 0.9 percent at the Paso .

However, the EIR further concludes that there could be significant cumulative effect on the overall surface water diversions and groundwater withdrawals by all of the downstream users (page ES-12). Based on our review of tho EIR, It Is our opinion that the writers of the document need to consider several other key hydrologic parameters in their. analysis of the potential for groundwater related impacts that could occur as a result of the expansion of the Salinas Reservoir storage capacity. -- ti Rick 04((man&Aaaoeratea.Eng(neer(ng9/\LpQ(et g�gu lQBUm Page 1 • Response to Salinas 9ese4 ;&pons/on CIA—Atoseadeco Mutuo/Wt. Company - FebrumV 8, YAN POTCNABL /MPRs: s Decrease in Storm Flow Events within the Salinas River The Atascadero Mutual Water Company (AMWC) pumps water from undertlow of the Safinas River (shallow aquifer) and from the Atascadero sub-basin of the Paso Robles Groundwater Basin (deep aquifer). In normal to wet rainfall/runoff years, two-thirds or more of the groundwater production is from underflow. However, in dry years more reliance is placed on the deep aquifer (Long Term Viability of the Water Supply of the City of Atascadero, Ca(ifomia, document prepared by the Morro Group,April, 1991). Recharge to the shallow (alluvial) aquifer Is therefore very Important to AMWC in terms of reliability and cost of operations. Estimates of recharge to the local aquifer was short of.prpopction by AMWC by.an.average of 4000 acre feet per year (afy) during the drought of 1987-1990. Production also exceeded recharge in the drought cycle of 1976-1977, 1959-1961, and 1947-1951 (page 2, Morro Group, 1991) The so-called "live stream agreement" requires the release of all water flowing Into-the Salinas Reservoir until a visible flow is observed between the dam and the confluence with the Nadmiento River(EIR, page 3-51). It Is inferred that the intent of this agreement is to allow for recharge to occur within.the Salinas River corridor, while allowing the Reservoir to capture excess surface water runoff during storm events. The EIR fails to discuss the impact of reduced storm flow events on the recharge capacity of the shallow and deep aquifers. Recharge could be Impacted by both a reduction in the scouring effect of the.stream sediments during flood events and the decreased amount of time when there is"high water"within the recharge area along the Salinas River corridor. We have briefly discussed below each of these potential impacts. Reel,, d Scour Wects During normal low flow(sometimes called "base flow') periods within the river corridor,the slow moving waters tend to deposit fine grained'sediments including sand, sllL.i3nd day.- These fine grained sediments tend to form a semi4mpervious layer at the interface between the water and the creek bottom. Recharge to the underlying alluvial and deep aquifers tends to be relatively slow during these base now periods. Total recharge is dependent on a number of variables Including (but not limited to) the amount of water within the creek, its depth, the width of the creek, sediment particle size,and the length of time the creek flows. Storm runoff events have the effect of scouring out the fine grained sediments from the central portions of the creek corridor by an increase in flow velocity. These higher flow periods expose coarse grained sediments (with their associated relatively higher permeability factors) to the water surface. Removal of the build up of the low permeability fine grained sediments daring low Rick 11qfrman 8t Asaoeiates.ErVineering Geologtst 8t Hydrologists page 2 ' - Rarponse to Sa/lnas Bcs( If Erpansloe EIR—Btosrodero Mutual Wi. ;r Componll fabroary B, 1994 flow periods by large and prolonged storm events is, in our opinion, critical to maintaining the recharge capability of the various shallow aquifers along the Salinas River corridor. The Salinas Reservoir currently spills over the dam on average every two years. (EIR, page 3- 78). Expansion of the reservoir will cause the reservoir to spill less frequently (EIR, page 3-88). The frequency and longevity of the reservoir non-spill cycles and the significance thereof is not presented within the EIR. The expansion of the reservoir will also cause a reduction in the peak monthly flow at Paso Robles gauging station of approximately 18 percent based on historic flow data and modeling analysis conducted in 1989 by Leedshill-Herkenfhoff (EIR, page 3-88). This reduction in peak storm water runoff cycles could reduce the amount of scouring effect within the Salinas River corridor,thereby effecting the amount of recharge available for percolation.. Reduced Duration andJlow Volume within the Salinas River Corridor As described above, the frequency of dam overflow and reduction in peak monthly flows could reduce the amount of scouring effects within the creek corridor. Reduced scouring could, in tum, reduce the amount of recharge that occurs both within the shallow and deep aquifers that the AMWC is dependent on. While the "live stream agreement"will allow for the passage of surface water within the Salinas River during an average winter month, the amount of flow could be reduced because of the increased capacity of the Salinas Reservoir. The reduced peak flow volume within the Salinas River could also decrease recharge because of the lessening of the width,depth, and duration of flow. Maintaining a'base flown condition under the terms of the"live stream agreement' may not allow for the same amount of recharge to the local aquifer as compared to longer duration flood flow conditions that currently occur every other year, on average. in our opinion, the decrease In duration of high water conditions within the Salinas River corridor has not been adequately addressed within-the EIR. POTENT/RL.:M/T/O17TlO1VMEASIFUCS: It Is our opinion that the Atascadero Mutual Water Company should consider discussing possible mitigation measures with the City of San Luis Obispo that could allow for the construction of an - expanded Salinas Reservoir while, maintaining a reliable supply of groundwater for the users within the down stream sections of the Salinas River.Corridorif We have provided below a list of several possible mitigation measures that could be considered to reduce the possible hydrologic Impacts to the AMWC.

' _"_" fwbrvory 8, 1994 Modification to the 'Live Stream Agreement" The give stream agreement" could be modified to'allow for one or more "flood stage" runoff cycles to occur during the winter months to improve the scouring effect within the creek corridor, thereby improving the potential for recharge into the underlying aquifer. The basis for the timing and duration of the release of flood stage waters could be based on historic flow data from the Salinas River near Atascadero or other appropriate area. Other wording could be developed that lengthens the duration of high water runoff cycles during the winter months to improve the recharge potential. Simply allowing what will be a lower than average"base flow"to occur during the winter runoff season (as Is currently allowed under the terms of the existing live stream agreement) does not insure that recharge will not be impacted. It.is these,"unknown" possible reductions in recharge potential that should be considered in much greater detail within the final EIR.. Controlled Releases of Stored Water into the Salinas River Because the AMWC is very dependent on its shallow (alluvial) aquifer for much of its water demand, the Salinas Reservoir Water Authority could provide for release of stored water during a"drought emergency"defined by a rfuutuaily negotiated agreement.` An alternative to this plan would be to construct a pipeline,from-the Salinas Reservoir'(or as part of the Nacimiento Reservoir, shared use plan)directly to Atascadero that could be activated during a severe water shortage.

Prior to our discussion, I made a quick review of the Woodward Clyde report regarding this proposed project and found it to be a pro-project statement without significant concern for the downstream users of the aquifers along the Salinas River drainage. This is to be expected, since Woodward - Clyde are consultants to the City•of San Luis Obispo, the beneficiary of such a. project and one that does not lie within the Salinas River drainage system. My initial concerns are as follows: 1. I suggest that under the current California groundwater law, the City of San Luis Obispo would ever be able to obtain other than surplus waters from the mtf r13 ^ -PO drainage since they lie outside of this major watershed. .However, two items should be given close attention. (a) Does the legal doctrine of prescription, especially when one considers the large amount of money as well as time frame involved with this project and when coupled with the modern concept of "intervening public interest," possibly alter or expand the ability to prescript outside of one's groundwater basins? and (b) With the greatly expanding need for water in the Southwestern United States, and particularly in California, one has to expect that the California constitutional concept of "highest and best use" of the water supply will outweigh the hundred years of case law that has long protected the groundwater rights of the individual property owners. In short, the water law will surely evolve in the immediate future towards what the politicians and the courts will decide is the "highest and best use". _- EXHIBIT F 1400 NOR-ni FAMVIF W • GOLZMA.

I am not intimately familiar with the referred to Live Stream Agreement, but one should be suspect of reducing the periodic flooding in a river system while believing that a trickle of water down a braided stream such as the Salinas River is sufficient protection for adequately recharging either the riparian gravels or the deeper associated aquifers. This is a complex relationship beyond the scope of this brief memo. I would suggest, however, that not only further studies be demanded by mutually agreed upon specialists in this field., but that the Live Stream Agreement, if found to be inadequate, be expanded to the benefit of Atascadero in order to insure that San Luis Obispo takes only those waters that are truly surplus to the drainage. In essence, if a shortage should occur, especially during a drought, downstream users have priority over all waters in the Reservoir necessary to insure the viability of the downstream aquifers. Thus I recommend a close examination of the legal rights of the City of San Luis Obispo to any but the surplus waters in the Salinas River drainage as well as the adequacy of the Live Stream Agreement to protect both the shallow and the deep aquifers. Perhaps an agreement can be worked out to benefit all, whereby during times of water shortage sufficient releases or availability of water are made to satisfy the needs of the Atascadero Water Company and other downstream users. If I can be of further aid or partake in any discussions, as it feels good to be asked during one's retirement years, please call upon me.

Bos 31 San Luis Obispo, California 93406-0031 Re: Salinas Reservoir Expansion Project, Draft Environmental Impact Report, Comments by Sinscheimer Schiebelhut & Baggett Dear Mr. Green: The following is provided in response to your follow-up comments dated March 11, 1994, on the Salinas Reservoir Expansion, Draft Environmental Impact Report (DEIR) . As a general note, the City has addressed these issues in- detail in its final EIR. In doing so, the City has analyzed the data contained in 1991 Moro Group Report. This information and analysis has been used in compilation of the final EIR. Thus you will find a more -comprehensive response to your concerns in the response to comments section of the final EIR. To briefly address your March 11, 1994, letter. . Section 3.4 of the DEIR addressed the downstream flow reduction impacts associated with the project. The impact of drought considerations on the recharge of the Salinas River and Atascadero sub-basin of the Paso Robles Ground- water Basin have been examined. Once the expanded reservoir -Ys filled, downstream flow effects would be similar to the current situation. A recharge area can be defined as that portion of the drainage basin in which the net saturated flow ofgroundwater is directed away from the water table. In a recharge area, the water table usually lies at some depth; in a discharge area, the water table is usually at or very near the surface. The Live Stream Agreement provides for a visible surface flow in the Salinas River resulting in a water table being at or near the surface. As a consequence, scouring effects from flood flows would be insignificant in terms of recharge to the groundwater basin. EXHIBIT G Mr. Green May 2, 1994 Page 2 The DEIR has previously noted flow reductions in the Salinas River could potentially reduce the quantity of recharge ' from the river bed into the groundwater basin. The Live Stream Agreement requires all reservoir inflow be released unless there is a visible stream to the confluence with the Nacimiento River and the reservoir captures water primarily during the wet winter months. Because the rate of recharge is also a function of the deep permeable sediments and a water table that does not rise to ground surface, a reduction in the duration of high water conditions will have no significant effect on recharge as, long as the Live Stre4.., agreement is in effi.Ct supplying a' visible El oiw of water at the surface. Perhaps, the most efficient nest step is for you to review the final EIR when it is available. If you .have any additional comments or concerns after your review of the final EIR, please contact Mr. Gary Henderson, City of San Luis Obispo, Water Division Manager, (805) 781-7237.

Box 6075 Atascadero, CA 93423 SUBJECT.- Comments on Revised Draft EIR for the Proposed Salinas Reservoir Expansion Project. Dear Mr. Weathers: As requested, Cleath& Associates has reviewed portions of the above-referenced draft EIR relating to potential impacts to the Atascadero Mutual Water Company (AMWC) water resources. This letter presents the results of the review. Included herein is an evaluation and discussion of the assumptions and methods used by EIR consultant Woodward-Clyde with specific recommendations for improving the impacts analyses. The assessment of potentially significant impacts from the proposed project on AMWC water resources involved running a spreadsheet model developed by the City of San Luis Obispo, estimating Salinas River flows at Atascadei-o, and correlating the estimated flows with water levels in AMWC Well 1 (shallow) and Well 7 (deep). Each of the three tasks are discussed below. Spreadsheet Model The spreadsheet model developed by the City of San Luis Obispo runs on a monthly time-step and was used by Woodward-Clyde to estimate reductions in reservoir spills under two scenarios, the"existing dam case"and the"raised dam case^. A yield value of 10,000 afy was used for both existing and raised dam scenarios. It is not reasonable to assume that the City would withdraw the same amount of water, even under worst-case conditions, from the existing reservoir than from the raised dam reservoir. The raised dam reservoir reportedly increases the safe yield of the dam by 1,650 acre-feet per year (afy). Therefore, the City would plan on diverting, on average, 1,650 acre-feet more than it could now(the reservoir's safe yield was estimated at 4,800 afy in the City's Water Master Plan, 1986). Under worst- case conditions the safe yield of the reservoir could be exceeded for several years, however, by assuming the withdrawals under the two scenarios would be the same, the EIR consultant is assuming the City would knowingly overdraft the reservoir at a great rate under existing conditions than under the raised _.C:%A?Vn91El R%c e+nt EXHIBIT H Jv1Y 17. 1197 dam conditions. This is effectively changing the operational management of the dam between the two scenarios,which is not appropriate. If 10,000 afy is Woodward-Clyde's selection for an appropriate withdrawal amount for worst-case conditions under the raised dam, then the existing dam withdrawals should be no more than 8,350 afy. In addition,besides mentioning that the existing facilities cannot physically convey 10,000 afy from the reservoir, the draft EIR should clearly state that this value is used solely for impacts assessment and is greater than both the reservoir safe yield and the permitted diversion amount. Cleath&Associates recommends that the maximum historical withdrawal by the City in the model period (7,272 acre-feet)be used for the existing dam yield value and the maximum permitted diversion from the reservoir(8,977 afy) used for the raised dam yield value. These values are probably more in-line with actual dam operations under worst-case conditions. The spreadsheet model is run on a monthly time-step but the results are reported on an annual basis. Potential impacts of reduced flows on a water supply includes both long-term and short-term impacts. Averaging the potential impacts of the proposed project to water resources on an annual basis does not address the short-term impacts. Both the spreadsheet and data sets are available on a monthly basis. According to the current draft ETR impacts analyses,the greatest potentially significant impacts to downstream wells attributable to a raised dam would have occurred under 1993 conditions. Therefore, in addition to summarizing the impacts assessment on an annual basis for the selected 1972-1994 time period,the critical period in 1993 should also be analyzed and presented on a monthly basis. Cleath& Associates recommends performing the monthly analysis between October 1, 1992 and September 30, 1994. The validity of the City's spreadsheet model in performing the spill reduction calculations has been reviewed and deemed acceptable by the Woodward-Clyde. It would be helpful for technical review, however,for the EIR consultant to provide an example calculation of the monthly spill, to explain bow reservoir evaporation is adjusted for the model scenarios;to identify the monthly variation of City yield over the year, and to identify any reservoir diversions that were limited by the minimum pool requirements. Salinas River Flow Estimates The estimates of flow at Atascadero used in the draft EIR were from a study for the City of Atascadero by The Morro Group (Long-term Viability of Water Supply, City of Atascadero, March 1991). The methods used by The Morro Group to estimate flows between 1984 and 1989 (and used by Woodward- Clyde to extend the estimates through 1994) are based on a tenuous correlation between estima' stream flow at Atascadero with gaged stream flow at Paso Robles. Data on the pTots from which .. P:\ANAA97E 10.\dd®lf.t a.wpd 2 1•s1, 17. 1997 ■ algorithms for high- and low-flow conditions were derived is scattered and the resulting estimates are highly questionable(see Figure 5,page 16 of The Morro Group report). The Morro Group did not use, or did not have access to, the reservoir inflow data available to the EIR consultant. There is ample data to derive flow estimates for an appropriate point in the channel downstream of the dam. Besides reservoir inflow data,gaged records are available for Santa Margarita Creek,Trout Creek and Yerba Buena Creek from which these and other watershed contributions downstream of the dam may be estimated. Although the estimated flows would be the same for the baseline and project runs, the magnitude of the flows affect the degree of impact and is a major component of the impacts assessment. A greater level of effort by the EIR consultant in providing reasonable flow estimates is warranted. Water Level Estimates for AMWC Wells The last step performed in the impacts assessment for water resources was a calculation of the amount of water level decline at selected AMWC water supply wells from the raised dam project. The two wells . used by Woodward-Clyde for correlating water levels with stream flow are Well.l (shallow)and Well 7(deep). Neither one of these AMWC wells will necessarily incur the greatest impact from the project. Well 1 is at the confluence with Atascadero Creek and would benefit from runoff in that watershed. Upstream wells(such as Well 5 and Well 12)that are above the confluence of Atascadero Creek may be more sensitive to Salinas Reservoir operations. The EIR consultant assumes but has not shown that Well 1 and Well 7 are suitable for representing the worst-case impacts of the project on AMWC water resources. A review of available AMWC well information is recommended to identify the shallow and deep wells which experience the greatest drops in production due to water level declines and are the most sensitive to Salinas River flows. Correlating water level declines and well production losses is important for impacts assessment. The incremental water level declines due to the raised dam estimated for AMWC wells should be interpreted in terms of possible losses in production. A determination of pumping water levels (and the corresponding static levels)below which significant ant production losses occur at the appropriate AMWC wells would facilitate an impartial assessment of the project impacts. The comparison of modeled monthly water levels at these wells under existing and raised dam scenarios for the time period from October 1, 1992 through September 30, 1994, along with identification of the critical window where production drops in each well would show whether or not there was a significant impact on well production. Monthly production and water level data to perform these comparisons is available. As drafted, the EIR reports the average and maximum annual incremental decline in water levels and declares them not significant, without any hydrogeologic rationale to support this assertion. Average annual water levels and the average estimated annual flows were used to correlate water levels with estimated stream flow in the draft EIR. Due to the cyclic nature of water levels and stream flow, r:werc9�eacom.�c,. �a 3 July », 1091 the data should be correlated on a monthly time-step. This would provide many more data points and should improve the correlation. Actual well production figures may also be used to adjust historical water levels slightly up or down to control this third variable. Estimated water levels using historical flows and the algorithms in the draft EIR are within about 5 feet of the actual historical water levels for the shallow well and deviate up to about 25 feet of the actual historical water levels for the deep well. The incremental difference between the baseline and project scenarios are relative and therefore not subject to as great a variation. When comparing the modeled water level estimates under baseline and project conditions to the depth at which significant production losses occur,however,the accuracy of both the water level estimates and the incremental differences are important. Given the relatively.wide distribution of water levels at similar stream flow rates, water level estimates should reflect the lowest possible water level (worst case)for a given flow rate. There are several ways of adjusting the correlation curve to reflect worst-case, such as by subtracting an appropriate value from all water levels(effectively lowering the curve), or by using only the lowest water levels for deriving the . best-fit line. For example, in Figure 3.49 of the draft EIR, lowering the correlation curve by about four feet would result in conservatively modeled water level estimates appropriate for the impacts analys Conclusions The assessment of potentially significant impacts to AMWC water resources performed in the draft EIR has several major shortcomings, as listed below. • Yield assumptions used in the scenarios and the averaging of impacts on an annual basis are not appropriate. • Salinas River flow estimates at Atascadero are from previous work using limited data and questionable correlations. • The AMWC wells used for impacts assessment may not be those most severely affected by the raised dam project. • The correlation between water levels and river flow was made on an average annual basis instead of on a monthly basis and was not adjusted to reflect worst-case conditions. • No information was developed which would indicate whether or not the incremental water level declines attributable to the raised dam project would significantly impact AMWC production. The overall level of effort performed to quantify the impact and assess its degree of significance is not sufficient given the tremendous importance•of water resources in San Luis Obispo County_ The specific recommendations given in this letter should significantly improve the information quality for the impacts assessment. _ -- P:\A,9T\97EI¢\c9m9nt�.�p7 4 July 17. 1997 u1 :--.%uF- c ieacn ana assaciat-es out 0YJ- 1 / 00 r .uo ■ If you have any questions or comments regarding this letter, please do not hesitate to contact our office.

In order to get more water , the City proposes to raise the height of the Salinas Dam by 19 feet . While that might not seem much , the scope of the project is immense . The capacity of the dam would be increased 75% from' 23 , 843 acre feet to 41 ,792 acre feet . The project would result in periodic inundation of an additional 395 acres of wetlands , riparian habitat and oak woodlands , including 16 ,050 linear feet of stream habitat , 73 acres of pine-oak woodland containing 1639 coast live oaks , 633 blue oaks , and 198 valley oaks , for a total of 2470 oak trees , plus 469 gray pines . Also included in the periodic innundation zone are 35 .6 acres of willow scrub/woodland , 3 .9 acres of mixed riparian woodland , 12 . 2 acres of riparian forest , and degradation of 22 . 1 acres of riparian woodland understory owing to periodic innundation . The area to be inundated by the raised dam and disturbed by the relocation of recreational resources contains many species of special concern , such as the Southwestern Pond Turtle and the Two- Striped Garter Snake, as well as several federally and state endangered and threatened species , including the Bald Eagle , California Condor , White-tailed Kite , American Peregrine Falcon , Least Bell 's Vireo , Southwestern Willow Flycatcher , California Red- legged Frog . Although the City claims that there are no threatened Steelhead Trout below the dam, recent evidence suggests otherwise , and until the dam was built , they were abundant in the Salinas River . In connection with the project , virtually all of the current recreational facilities surrounding the lake will be moved , with new roads to be built and considerable cut-and-fill operations to be undertaken . In order to accommodate the increased capacity of Santa Margarita Lake , the dam will need to be substantially strengthened and the spillway will need to be armored . Before the City can undertake the project as planned , it must obtain an extension of time to complete the beneficial use granted in its water rights permit in 1941 . The State Water Resources Control Board will shortly issue its decision regarding granting the City another 10 years to complete the project . . In June 1998 , the City certified a Final Environmental Impact Report . But the FEIR does not adequately address concern adverse impacts to habitat above and below the dam, incr are EIVED 11/9/00 untitled 3 Page 1 No V 0 9 2000 SLO CITY CLERK seismic vulnerability because the of greatly increased volume of water to be impounded behind the dam, adverse impacts to downstream water users , and the growth-inducing effects of the added water supply . To some extent , the State Water Resources Control Board has recognized these deficiencies and is expected to order additional studies before it will grant the City an extension of time to increase the height of the dam. The City ' s Plans To Mitigate for Lost Habitat Are Inadequate and Illusory ` The City recognizes that the law requires it to mitigate the detrimental impacts to the environment that the dam project will cause . However , it has not yet developed any tangible mitigation plans for the loss of riparian habitat and wetlands , and admits that any habitat restoration or creation will not reach fruition until 5 to 15 years after they are begun . The endangered and threatened species will have nowhere to be in the interim, and may be lost forever . Although the City claims it will develop a mitigation plan that will rely on restoring and/or enhancing native habitats on nearby private lands with willing landowners , thus far no land has been contracted . Currently , the only property the City is attempting to acquire is 49 acres of steep , not-in-kind habitat out of the Salinas watershed and 15 miles from the project , property that cannot provide the habitat that will be destroyed by the project . Even worse , there is some evidence that the City in fact will attempt to avoid its obligation to replace destroyed habitat by offering monetary compensation to public or private agencies , as if money can mitigate destruction of habitat and species . Seismic Concerns Recently the City received a Dam Safety Evaluation Study undertaken in order to meet the requirements of the California Department of Water Resources , Division of Safety of Dams requirements . This report concludes that the FEIR did not accurately consider the magnitude of earthquake possible along the Rinconada fault . The study concluded that the dam will be seismically unsafe unless it is strengthened beyond the degree of strengthening contemplated in the FEIR, increasing the cost of the project by $11 ,000 ,000 or over 50%. The City Did Not Plan To Mitigate for the Decreased Amount of Water it Would Be Releasing Downstream Although the City claims the increased size of the dam will have no impact or only minimal impact on the river downstream, both the State Water Resources Control Board and the National Marine 11/9/00 untitled 3 Page 2 Fisheries Service has determined otherwise . In its draft order , the SWRCB concluded that the raised dam will contribute to the overdraft in the Paso Robles groundwater basin . The SWRCB also noted that it could not conclude that there were no Steelhead in the river below the dam or that the project would not adversely impact any steelhead that might be present . In addition , the National Marine Fisheries Service is also concerned with the downstream impacts of even the current operation of the Dam and is requesting the SWRCB to order interim releases of water . This Project Will Induce Growth and Development . The stated purpose of the project is to provide the City with an additional 1650 acre feet of water per year (AFY) . The City projects that it will require 3861 AFY of water by the year 2022 to meet growth projections . This project is projected to supply 43% of that anticipated need . That 1650 AFY could easily be supplied by water conservation and by buying up state water rights that are currently available . In fact , however , the project will supply an additional 2000 AFY for increased reserves , which can potentially provide for more growth than the City claims . . The FEIR projects that raising the dam will provide water to accommodate a portion of the City's planned growth between now and 2022 . The FEIR projects water need at 145 gallons of water per person per day , which would allow for 5000 additional people . However , the current water usage is 123 gallons per person per day. If current water use rema.ins the same, the water contemplated by this project can accommodate an additional 12 ,000 people . If the 2000 AFY is used , then over 25 ,000 additional people could be accommodated . m Marge Erickson is an attorney (for 20 years) in Santa Barbara with a keen interest in environmental issue .

This request is based on new information showing that the seismic and dam safety impacts of the reservoir expansion will be significantly more severe than shown in the original EIR for the project This new dam safety information was prepared by San Luis Obispo's engineering consultant,URS Greiner Woodward Clyde,after the original EIR was certified in 1998. The new dam safety analysis concludes that if the storage capacity of Salinas Reservoir were increased,the existing Salinas Dam would not be strong enough to withstand the design earthquake on the Rinconada fault In other words,the new studies conclude that the project,as originally designed and proposed,cannot be built without risking catastrophic dam failure. A copy of Volumes I and H of the Salinas Reservoir Expansion Project Dam Safety Evaluation Final Report prepared for the City of San Luis Obispo by URS Greiner Woodward Clyde is enclosed with this letter. Documents summarizing this new dam failure analysis and describing project redesign options were presented to the City Council in the July 18,2000,City of San Luis Obispo Council Agenda Report("Council Agenda Report"). The agenda packet contained two attachments: (1) Executive Summary of"Salinas Reservoir Expansion Project Dam Safety Evaluation" ("Executive Summary")and (2)July 5, 2000,letter from San Luis Obispo's dam expansion consultant,URS Greiner Woodward Clyde,to San Luis Obispo's water division manager,Gary ru0w uTY OFFICE 422 CENTURY PARK DRIVE,SUITE A BAY AREA OFFICE P.O.BOX 77 IPSO HARRISON STREET.SUITE 1100 VUBA CITY.CALIFORNIA B5902b0776 OAKLAND.CALIFORNIA 94612 TELEPHONCI(B2o)674-0761 TELEPHONE:(610)293-0760 FACSIMILE:(630)6T1-0990 FACSIMILE:(610)829.9104 City Council City of San Luis Obispo October 20,2000 Page 2 Henderson("URS Letter'). Copies of these documents are enclosed with this . letter. The Executive Summary of the Dam Safety Evaluation states that the results of the computer analy-is indicate that for the case of the raised reservoir level, "the stresses induced in the dam by the Maximum Credible Earthquake on the Rinconada fault would be much greater than the strength of the concrete in many portions of the dam. As such,the analyses indicate that the dam is not strong enough to withstand strong ground shaking with the increased load from a raised reservoir. The dam,under the proposed reservoir raise,does not satisfy modern seismic performance evaluation criteria such as those currently used by DSOD [Division of Safety of Dams]." (Executive Summary,pp. 2-3 (emphasis added).) The URS letter suggests two conceptual approaches for seismically strengthening Salinas Dam,each of which involves a major redesign of the proposed project and neither of which was discussed in the Salinas Reservoir Enlargement Project EIR. This new information requires preparation of a subsequent EIR under the California Environmental Quality Act("CEQA"). Public Resources Code section 21166 and State CEQA Guidelines section 15162 provide that a subsequent EIR must be prepared when any of the following three events occurs: (1) new information,which was not known and could not have been known at the time the environmental impact report was certified as complete becomes available. (2) substantial changes occur with respect to the circumstances under which the project is being undertaken which will require major revisions in the environmental impact report;or (3) substantial changes are proposed in the project which will require major revisions of the EIR; Pub. Res. Code§21166. Although only one of these three events need occur to require preparation of a subsequent EIR,the new seismic and dam safety analysis produced by San Luis's engineering consultant requires preparation of a subsequent EIR under all three tests. First, the seismic and dam safety analysis produced in June and July 2000 constitutes new information that was not known,and could not have been known,when San Luis certified its EIR in 1998,and thus triggers Public City Council City of San Luis Obispo October 20,2000 Page 3 Resources Code section 21166(c). The Agenda Report even calls the new seismic data "new information." (See Council Agenda Report at 4.) CEQA Guideline section 15162 clarifies that the type of new information that triggers the requirement to'r repare a subsequent EIR includes information showing that the project will have one or more significant effects not discussed in the previous EIR or showing that significant effects previously examined will be substantially more severe than shown in the previous EIR. The new-information shows that if the dam is expanded as San Luis proposes,it"would not be strong enough to withstand the design earthquake on the Rinconada fault." (Council Agenda Report at 4). Although previous seismic studies indicated that an expanded dam would be stable during the design earthquake, "current analyses show that the dam would not be strong enough to withstand the design earthquake." (Executive Summary at 3.) Accordingly, "[t]he dam with a raised reservoir level does not satisfy modern seismic performance evaluation criteria such as those currently used by DSOD." (Executive Summary at 5.) This information establishes that the project as described in the FEIR will have significant seismic impacts not discussed in the FEIR and substantially more severe than acknowledged in the section of the FEIR dealing with seismicity and faulting. Second,the new data shows that earthquake forces acting on the dam are likely to be 70 percent greater than the forces previously assumed. (See Council Agenda Report at 3;Executive Summary at 4-5.) The increase in the severity of the expected earthquake forces constitutes a substantial change in circumstances under which the project is being undertaken,triggering Public Resources Code section 21166(b). Third, the major new construction proposed to address the greater earthquake forces would transform the dam expansion project into something substantially different from the project proposed by San Luis and analyzed in its EIR. The EIR analyzed installation of drum gates at the dam's existing spillway, without any strengthening of the concrete arch dam structure. The new information shows that either the dam thickness must be substantially increased—an approach that might not be technically feasible—or a massive concrete buttress must be constructed to support the downstream side of the dam. (See Council Agenda Report at 3;June 30,2000,URS letter.) Either approach constitutes a substantial change to San Luis'proposed project that would cause potentially significant adverse environmental impacts that require major revisions to the existing EIR,triggering Public Resources Code section 21166(a).) City Council City of San Luis Obispo October 20,2000 Page 4 The URS Letter identifies a list of"CONS" for each approach to addressing the project's seismic safety problems. Building a massive concrete buttress would give the dam a "significantly different" appearance, (URS Letter at 4), which raises new aesthetic impact issues. Aggregate required to make the buttress concrete"can not be prodor:ed on site and will need to be imported", (id.),which raises new traffic and air quality issues. Building a buttress would prevent installation of the proposed spillway drum gates,which"could restrict reservoir operation flexibility." (Id.) This raises questions about all resource impacts affected by the dam's proposed operational regime, including harm to downstream water users,like Paso Robles..None of these potential adverse environmental impacts have been analyzed and subjected to public review and comment,as required by CEQA. A subsequent EIR is necessary under CEQA to present the new dam failure analysis,to describe the recommended alternatives for redesigning the dam expansion project to address the threat of catastrophic failure,to analyze the potential environmental impacts of the alternative project designs and to prescribe mitigation measures to avoid or reduce impacts. Only if the City of San Luis Obispo prepares a subsequent EIR containing this information will the public,other government agencies with authority to approve the project and the City Council,itself,have the information needed to understand the public safety" ' and environmental consequences of approving a dam expansion project. Just last month,in a case involving the State Water Project,Planning and Conservation league v. Department of Water Resources,83 Cal. App.4th 892(2000), the court of appeal stated: "The ultimate decision of whether to approve a project,be that decision right or wrong,is a nullity if based upon an EIR that does not provide the decision-makers,and the public, with the information about the project that is required by CEQA." Id. at 916. The error is prejudicial"if the failure to include relevant information precludes informed decision-making and informed public participation, thereby thwarting the statutory goals of the EIR process."Id. The court referred to the"essential mission of CEQA to present a full disclosure of the potential environmental impacts of the proposal." Id. Any decision by the City Council to approve the proposed dam expansion project without first disclosing important information regarding seismic impacts and dam.safety in a subsequent EIR would jeopardize public safety and violate CEQA. San Luis Obispo may not lawfully approve the proposed Salinas Dam Expansion Project unless and until the City prepares a subsequent EIR But even more important—the City of El Paso de Robles and other communities lie downstream of Salinas Dam. And there is no possible justification for the elected public servants on San Luis Obispo's City Council to approve a water supply City Council City of San Luis Obispo October 20,2000 Page 5 expansion project based on a design that threatens downstream communities with catastrophic loss of life and property damage from dam failure. The duty to avoid catastrophic dam failure must overcome the desire to support new growth and development by expanding the water supply from Salinas Reservoir. Conclusion The new seismic analysis shows that the Salinas Reservoir Enlargement Project, as described and analyzed in the original FEIR,has dam safety problems and would risk dam failure in the event of a maximum credible earthquake. The Salinas Reservoir expansion,as proposed,will not meet the standards of the Division of Safety of Dams. This is an important impact—it involves the potential for catastrophic downstream flooding. In light of these public safety problems,the City Council must not approve construction of the reservoir enlargement project as proposed. Nor can the City of San Luis Obispo approve an alternate design, until it prepares a subsequent EIR disclosing the true impacts of the project related to seismicity and faulting and addressing all impacts of any alternative design intended to address the seismic-impacts. Finally,the City of El Paso de Robles requests that San Luis Obispo notify Paso Robles of any upcoming City Council meeting at which the Salinas Reservoir Expansion Project will be considered as an action item.

Baggett,Jr. Acting Chair State Water Resources Control Board 901 P Street Sacramento,California 95812-0100 Re: Petition for Extension of time on Permit 5882 Comments of City of El Paso de Robles on Draft Decision Dear Chairman Baggett The City of El Paso de Robles ("Paso Robles" or "City") submits the following comments on the State Water Resources Control Board's ("SWRCB" or "Board") August 24, 2000, Draft Order conditionally granting the City of San Luis Obispo's petition for extension of time to construct an expanded Salinas Reservoir and to put the resulting additional stored water to full beneficial use. PROTECTION OF THE PASO ROBLES GROUNDWATER BASIN Conditions in the Draft Order address important concerns of the City regarding the significant adverse impact that an expanded Salinas Reservoir would have on the Paso Robles Groundwater Basin. Specifically, Condition 2 provides that San Luis Obispo's collection to storage that exceeds 23,000 acre- feet per water year "shall not contribute to overdraft conditions in the Paso Robles Groundwater Basin." The condition further requires San Luis Obispo to prepare and submit a reservoir operations plan specifying how the Salinas Reservoir will be operated to comply with this requirement prior to collecting any amount exceeding 23,000 AF per water year. Paso Robles supports the concept of Condition No. 2 and appreciates the Board's recognition of the need to protect the groundwater basin. However, there are two problems with Condition 2 as written in the Draft Order. First, YUBA CITY OFFICE 422 CENTURY PARK DRIVE.SUITE A BAY AREA OFFICE P.O.BOX'/70 1990 HARRISON STREET.SUITE 1300 YUBA CITY.CALIFORNIA 96992-0776 OAKLAND.CALIFORNIA 94612 TELEPHONE:(530)074-9761 TELEPHONE:C610)B72-6700 c"�a.N.l• /c•r..c+i-noon FAf,91MI1 FlKlnl R\Y-O.f1Y Arthur G. Baggett,Jr. Acting Chair State Water Resources Control Board September 14, 2000 Page 2 the Condition does not require submission of a reservoir operations plan prior to construction of the reservoir enlargement, but only prior to collection of more than 23,000 AF per water year. Because it may be difficult to devise an operations plan or physical solution that fully protects the groundwater basin, in order to insure that such a plan or solution actually is feasible, the plan or physical solution should be presented to the Chief of the Division of Water Rights (and to Paso Robles for comment) prior to construction of the enlarged reservoir. After San Luis has already expended $20 million or $30 million to construct the reservoir, the pressure to approve a plan, even if it does not fully protect the basin, will be overwhelming. This condition, like Condition 3, should apply prior to San Luis' proceeding with construction. Second, the impacts of the Salinas Reservoir on the Paso Robles Groundwater Basin stem from reduced spills once the storage capacity of the reservoir exceeds its existing storage capacity. Thus, the trigger for the operations plan should be further diversions to storage once the amount in storage exceeds 23,843 AF, the capacity of the existing reservoir given on page 24 of the Draft Order. Requiring the groundwater basin to be fully protected only when San Luis collects over 23,000 AF to storage In a sib water year, would leave the basin unprotected from the physical effects of storage of amounts. greater than the existing reservoir could hold whenever holdover storage and collection to storage in a given year.result in storage of more than 23,843 AF,but San Luis collects less than 23,000 AF in that year. For example, carryover storage of 12,000 AF and collection to storage of an additional 20,000 AF in a single water year could result in 32,000 AF of storage, far more than the existing capacity of the reservoir, and would reduce spills to the Salinas River and recharge to the Paso Robles Groundwater Basin, but would not appear to require an operations plan to be filed under Condition 2 as written. Arthur G. Baggett,Jr. Acting Chair State Water Resources Control Board September 14,2000 Page 3 Accordingly, Paso Robles suggests that the first two paragraphs of Condition 2 be reworded as follows: San Luis Obispo's eal ems to storage t4at exEeeds of more than the existing, reservoir capacity of 23,000 acre-feet (AF) p�shall not contribute to overdraft conditions in the Paso Robles Groundwater Basin. e)(E,,,,a:ng .3 999 AP per- water- year- prior to proceeding with construction for the purpose of enlarging the capacity of Salinas Reservoir. San Luis Obispo shall submit to the Chief, Division of Water Rights, for approval and modification, if necessary, a reservoir operations plan specifying how the Salinas Reservoir will be operated to comply with this requirement. The plan shall be provided to the City of Paso Robles for comment. The plan must include or identify the following: (1) an evaluation of the extent to which ee4e storage in excess of 23,000 AF per water- has the potential to reduce groundwater recharge in the Paso Robles Groundwater Basin, (2) measures San Luis Obispo will take to avoid reducing, by any amount the annual recharge of the Paso Robles Groundwater Basin attributable to Salinas River flow from the watershed area upstream of Salinas Reservoir whenever ^e"e� e storage exceeds 23,000 AF-peF tea, (3) the location and type of all measuring devices to be used, and (4) the frequency of measurement. The plan also must contain an analysis of how the proposed measures will avoid project-related reductions to average annual recharge of the groundwater basin. The plan must be based on water year data or modeling. A water year begins on October 1 of each year and ends on September 30 of the succeeding year. The Draft Order states that the SWRCB will prohibit operation of the reservoir in a manner that contributes to increased overdraft of the basin, and that San Luis will be required to develop a reservoir operations plan to this effect. Draft Order,page 27. The SWRCB must assure that Condition 2 is written in a way that will accomplish this result. Arthur G. Baggett,Jr. Acting Chair State Water Resources Control Board September 14, 2000 Page 4 COMPLIANCE WITH THE CALIFORNIA ENVIRONMENTAL QUALITY ACT The Draft Order does not adequately address problems arising from The Salinas Reservoir Enlargement Project Environmental Impact Report (TIR"), which lacks important information that the SWRCB needs in order to perform its duties as a responsible agency under the California Environmental Quality Act ("CEQA"). A. Analysis of Seismic Safety was Impermissibly Deferred in the EIR. During the proceedings on San Luis' extension petition, Paso Robles pointed out that the EIR had been certified before studies to determine the extent of seismic and dam safety impacts had been concluded. Paso Robles objected to the failure to include current seismic safety analysis in the certified EIR on grounds that San Luis was impermissibly deferring analysis of potentially significant project impacts. (Closing Brief of Paso Robles at pp. 33- 34.) Deferring this analysis also deferred development of mitigation measures, project alternatives and analysis of potentially significant impacts of such measures and alternatives. The EIR determined that seismic impacts were potentially significant, but concluded that they would be mitigated to insignificance because final dam engineering would be subject to the approval of the Division of Safety of Dams ("DSOD"). However, it reached this conclusion even before the completion of the studies showing the extent and significance of the impacts, with no discussion of the mitigation measures that might be required if the danger of dam failure were greater than shown in previous studies, or of the impacts of such mitigation measures. . While the Draft Order alleges on page 38 that CEQA allows the adoption of performance standards as mitigation measures, the purported use of an objective performance standard as mitigation does not allow an agency to Arthur G. Baggett,Jr. Acting Chair State Water Resources Control Board September 14,2000 Page 5 postpone and omit the analysis of significant impacts themselves. 14 Cal. Code Regs. § 15126.2(a). Furthermore, deferring analysis of dam safety impacts and handing off mitigation to DSOD's approval process would not guarantee analysis or avoidance of new impacts resulting from whatever concrete mitigation measures DSOD might require. The CEQA Guidelines state that an EIR "shall" discuss the significant impacts of a mitigation measure if they are different from the impacts of the project as proposed. 14 Cal. Code Regs. § 15126.4(a)(1)(D). In Stevens v. City of Glendale, 125 Cal. App. 3d 986 (1981), the court held that CEQA was violated because responsible agencies and the public never had an opportunity to review and comment on a mitigation measure r developed after an EIR had been circulated for public and agency review. The court found that both the new mitigation measure and its potentially significant impacts had evaded review in violation of CEQA. Here, downstream entities at risk of flooding in the event of catastrophic dam failure are entitled to a meaningful description of what measures will be taken to mitigate this danger to a less-than-significant level. And the public, trustee and responsible agencies are entitled to know what the impacts of these mitigation measures will be. Under CEQA, "a paramount consideration is the right of the public to be informed in such a way that it can intelligently weigh the environmental consequences of any contemplated action and have an appropriate voice in the formulation of any decision." Mira Monte Homeowners Ass'n v. County of Ventura, 165 Cal. App. 3d 357,365 (1985). Arthur G. Baggett,Jr. Acting Chair State Water Resources Control Board September 14, 2000 Page 6 B. New Seismic and Dam Safety Information Requires Preparation of a Subsequent EIR. New seismic safety and dam design information developed by San Luis' consultants and submitted by Paso Robles as its proposed Exhibit 32 shows that Paso Robles' concerns about deferring the required dam safety analysis were well-founded. See Letter to Hearing Officer John Brown dated August 15, -2000 ("Paso Robles' letter-motion"), with attachments. The new analysis shows that, if enlarged in the manner proposed in the EIR, Salinas Reservoir would not meet current DSOD standards. This information demonstrates that the seismic impacts are significantly more severe than recognized in the EIR. Moreover, the major engineering changes that the new information says would be required to mitigate the greater seismic danger would themselves constitute a change in the project from what was presented in the current EIR. As more fully explained in Paso Robles' letter-motion dated August 15, 2000, seeking admission of the new dam safety and project redesign information, this new information requires the preparation of a subsequent EIR. Public Resources Code section 21166 and CEQA Guidelines section 15162 require preparation of a subsequent EIR to address new significant impacts or the increased severity of previously identified significant impacts as a result of: (1) substantial changes to the project; (2) substantial changes in the circumstances surrounding the project; or (3) new information that was unavailable when the EIR was certified. San Luis' new dam safety and project redesign information triggers all three requirements for preparing a subsequent EIR. The Draft Order rejects Paso Robles' request to augment the record with the documents containing this new information. Draft Order at p. 11. Paso Robles respectfully requests the Board not to adopt this part of the Draft Order, but to admit and consider the new dam safety and project redesign information. We believe that it is the Board's duty as a responsible agency to Arthur G. Baggett,Jr. Acting Chair State Water Resources Control Board September 14, 2000 Page 7 consider relevant new environmental information that becomes available. For the reasons given in these comments, Paso Robles also supports the California Sportfishing Protection Alliance's Motion to Require the City of San Luis Obispo to Prepare a Supplemental Environmental Impact Report and to Reopen the Hearing Record. The documents presented to the San Luis City Council as part of the July 18, 2000, Agenda Report show that the computer analyses indicate that for the case of the raised reservoir level, "the stresses induced in the dam by the Maximum Credible Earthquake on the Rinconada fault would be much greater than the strength of the concrete in many portions of the dam. Thus, the analyses indicate that the dam is not strong enough to withstand strong ground shaking with the increased load from a raised reservoir." The proposed dam expansion project cannot be built without a massive concrete buttress or thickening of the existing concrete arch dam to prevent catastrophic dam failure in an earthquake. The SWRCB cannot avoid the necessity of a subsequent EIR by simply imposing a condition requiring dam design to be approved by DSOD. See Draft Decision, section 8.4.6, page 39. San Luis' own new documents show that the expansion project described and analyzed in San Luis' current EIR does not satisfy DSOD requirements, and the changed project has never been analyzed. "An accurate, stable and finite project description is the sine qua non of an informative and legally sufficient EIR." County of Inyo v. City of Los Angeles, 71 Cal. App. 3d 185, 192-193 (1977). The technicalities of DSOD compliance may lie beyond the SWRCB's expertise, but it is well within the SWRCB's purview to conclude that the substantial new construction San Luis's consultants describe as necessary to comply with DSOD requirements may have its own potentially significant adverse environmental impacts on biological and water resources. For example, the EIR's analysis of "Impacts Due to Spillway Modification and Dam Arthur G. Baggett,Jr. Acting Chair State Water Resources Control Board September 14,2000 Page 8 Strengthening" concludes that "Construction activities at the base of the dam would remove 0.4 acre of freshwater marsh. The loss of this habitat is considered an adverse, but not significant impact because of the small area involved compared to similar habitat below the dam." (SWRCB Exh. 3 at 3.7-20 (emphasis added).) In light of the massive concrete buttress or arch support described in the new seismic safety and dam design information produced by San Luis's consultants, which involves new construction at the base of the dam, it is possible that additional freshwater marsh would be affected, or other new impacts may result. ' Further, the substantial added cost of reinforcing a raised Salinas Dam to withstand a design earthquake calls into question the adequacy of the alternatives analysis contained in San Luis' EIR. If dam safety problems raise the estimated $20 million project cost to $31 million, as San Luis' new seismic safety and design information suggests, the universe of potentially feasible water supply alternatives is expanded to include alternatives not fully considered in the EIR.' If San Luis offered $31 million to acquire and make use of entitlements to the Coastal Branch of the State Water Project ("SWP"), it might have found more than the 773 acre feet of available SWP water described in the EIR as insufficient and, therefore, an infeasible alternative. (See SWRCB Exh. 3, at 4-14.) SWP water would.avoid the significant impacts arising from inundating oak woodland at the enlarged reservoir site. See 14 Cal. Code Regs. ' In Mira Monte Homeowners Assn v. County of Ventura,supra,165 Cal.App.3d at 360-361, the court found that new information showing that a project would encroach upon an additional quarter acre of wetland was significant and triggered the need for a subsequent EIR. The lead agency's adoption of mitigation measures addressing the additional wetland impact did not satisfy CEQA,because neither the impact nor the measures had been subject to public review. Id. at 365. 2 The substantial cost increase described in San Luis'new seismic safety and dam design information also calls into question the validity of the conclusion in the Draft Order that"San Luis can make satisfactory progress on the project;'in part,because"San Luis does not anticipate problems with its ability to finance all phases of the project." (Draft Order at 18,19.) Arthur G. Baggett,Jr. Acting Chair State Water Resources Control Board September 14,2000 Page 9 § 15162(a)(3)(C) (subsequent EIR required where new information shows mitigation measures or alternatives previously found infeasible to be feasible and would substantially reduce one or more significant project effects). In light of the new information, the SWRCB should defer acting on the extension until after San Luis has prepared a subsequent EIR pursuant to Public Resources Code section 21166 addressing the substantial new construction required to make the dam safe and the corresponding impacts on biological, water and other resources. Or the Board itself should prepare a subsequent EIR under CEQA Guidelines section 15096 (e) (3). C. The SWRCB,as Responsible Agency,must Consider the Adequacy of the Existing EIR and the Necessity for a Subsequent EIR. Evidence already in the record shows that important information is missing from the EIR, making it inadequate for the SWRCB's purposes. See Closing Brief of Paso Robles at pp. 29-37; Reply Brief of Paso Robles at pp. 16- 18). Moreover, the new dam safety information produced for San Luis highlights the inadequacies of the seismic analysis in the current EIR and demonstrates that a subsequent document is required. It is hard to square the Draft Order's assertion that the SWRCB must conclusively presume the adequacy of San Luis' EIR, see e.g. Draft Order at p. 22 (first full paragraph), at p. 39 (Section 8.4.6)), with the CEQA Guidelines provision addressing the circumstance where "a responsible agency believes that the final EIR or negative declaration prepared by the lead agency is not adequate for use by the responsible agency . . . ." 14 Cal. Code Regs. § 15096(e) (emphasis added). This Guideline suggest that a responsible agency does evaluate the adequacy of an EIR for its use. CEQA gives responsible agencies several options when they are asked to approve a project based on an EIR that fails to provide all the information needed for that responsible agency to approve the project and make its Arthur G. Baggett,Jr. Acting Chair State Water Resources Control Board September 14, 2000 Page 10 findings. If the EIR is inadequate, the responsible agency may: (1) take the issue to court within 30 days after the lead agency files a notice of determination (which San Luis Obispo has not yet done); (2) prepare a subsequent EIR if permissible under section 15162; or (3) assume the lead agency role pursuant to CEQA Guidelines section 15052(a)(3). CEQA Guidelines §§ 15096(e), 15162-15164. Only if a responsible agency does none of these is it deemed to have waived any objection to the adequacy of the EIR. 14 Cal. Code Regs. § 15096(e)(2). Even then, the responsible agency is to reach its own conclusions on whether and how to approve the project. 14 Cal. Code Regs. § 15096(a). If it does not have sufficient information to make the findings required by CEQA Guidelines section 15092, the agency cannot approve the project. 14 Cal. Code Regs. § 15092. The Board's assertion that, as a responsible agency, it cannot evaluate the adequacy of San Luis' EIR makes no sense' and contradicts the plain language of CEQA Guidelines section 15096(e). Public Resources Code section 21167.2 and section 21167.3 come into play only after the lead agency has approved its project, and the statute of limitations on a CEQA lawsuit has been triggered. Until the statute has run, the responsible agency itself could challenge the EIR. Moreover, there is a key exception to the presumption of adequacy where circumstances warrant preparation of a subsequent EIR under Section 21166. Public Resources Code section 21167.2 states that "the environmental impact report shall be conclusively presumed to comply with the provisions of this division for purposes of its use by responsible agencies, unless the provisions of Section 21166 are applicable." Pub. Res. Code § 21167.2 3. If a lead agency submitted an EIR comprised of 100 blank pages with a cover sheet titled "EIR",the SWRCB,as a responsible agency,would hardly be compelled to presume that the EIR is adequate. Similarly,if an EIR's impact analyses repeatedly stated that impact studies would be done in the future and any necessary mitigation measures would be developed and approved by. the relevant trustee and responsible agencies,the SWRCB would be unable to make the requisite findings. Yet this is exactly the deferred approach to CEQA review that San Luis Obispo asks the SWRCB to embrace. The SWRCB should reject this approach. Arthur G. Baggett,Jr. Acting Chair State Water Resources Control Board September 14,2000 Page 11 (emphasis added). Section 21166 applies here, providing another reason that the EIR cannot be presumed to be adequate for the SWRCB's purposes. Section 21166 requires preparation of a subsequent EIR if changes proposed in the project require major revisions of the EIR, if changes in project circumstances require major revisions to the EIR, or if new information becomes available. Pub. Res. Code § 21166. These circumstances exist, and the new information has been provided to the Board, a responsible agency, prior to its approval of the project. The Board should ask San Luis as lead agency to prepare a subsequent EIR, or the Board could do so itself, as a responsible agency. CEQA Guidelines, §15096(e)(3). The Board, as a responsible agency, has an obligation to decide if San Luis' EIR is adequate for the Board's purposes and whether a subsequent EIR is required. The Board should not pretend that it is bound by conclusive presumptions that do not apply to the circumstances of this proceeding. D. The EIR Reveals that the Project would have Several Significant Impacts Lasting up to 15 Years,so the SWRCB is required to Adopt Statements of Overriding Considerations before Approving the Project. The Draft Order states that "it is unnecessary for the SWRCB to adopt any findings of overriding considerations for unmitigated significant impacts." (Draft Order at 37.) This is simply incorrect as a matter of CEQA law. Public Resources Code section 21081 and CEQA Guidelines sections 15091 through 15093 require a public agency to make findings of overriding considerations whenever significant impacts within the agency's jurisdiction will remain after mitigation. The EIR identifies seven significant biological impacts that cannot be mitigated to less-than-significant levels for various periods of time, up to 10 to 15 years. (See SWRCB Exh. 3 at ES-18, 20-22, 26.) For example, the summary table at page ES-18 concludes that impacts to botanical resources in the 395-acre inundation zone will be significant until the mitigation results in 146 acres of Arthur G. Baggett,Jr. Acting Chair State Water Resources Control Board September 14, 2000 Page 12 new or enhanced woodlands, which is "expected to require about 10 to 15 years." On page ES-26, the EIR concludes that the short-term cumulative impact on biological resources will be "significant until the mitigation is successful", a rather indefinite period. The Draft Order itself states that the Final EIR recognizes that the impacts to certain habitats are significant until the various replacement habitats become established. Draft Order, p. 37. It does not matter that these impacts may not be permanent. CEQA requires that EIRs give "due consideration to both the short-term and long-term effects" of proposed projects. 14 Cal. Code Regs. § 15126.2(a). Before granting San Luis' extension petition, the SWRCB would have to adopt statements of overriding considerations for all significant impacts within the Board's jurisdiction, even if they are short-term impacts. Pub. Res. Code § 21081; 14 Cal Code Regs. §§ 15091, 15093. The SWRCB would have to revise its Draft Order to comply with this requirement. CONCLUSION The Draft Order addresses Paso Robles' concerns about the impact of an expanded Salinas Reservoir on the Paso Robles Groundwater Basin and attempts to resolve them by Condition 2. The Board must assure that the wording of the Condition accomplishes the intent of the Board to prohibit operation of the reservoir in a manner that contributes to increased overdraft of the basin. The order fails to overcome the inadequacy of the EIR's seismic impact analysis. This inadequacy cannot be remedied by conditioning project approval upon some subsequent approval by DSOD. Such an approach threatens to make the dam expansion project a fait accompli at a point when obvious potential impacts of redesigning the project to obtain DSOD approval have never been considered pursuant to CEQA. Arthur G. Baggett,Jr. Acting Chair State Water Resources Control Board September 14,2000 Page 13 In this case, the SWRCB should decline to approve the extension petition and should continue this proceeding to allow San Luis to prepare a subsequent EIR providing the information that the SWRCB needs to understand the full environmental consequences of granting the petition. The public and other responsible and trustee agencies need and have a right to this information before the project is approved. Thank you for the opportunity to comment.

The documents contain relevant new information concerning the seismic and dam safety impacts of raising the level of Salinas Reservoir. They conclude that if the storage capacity of Salinas Reservoir were increased,the existing Salinas Dam would not be strong enough to withstand the design earthquake on the Rinconada fault. The documents, recently obtained from the City of San Luis Obispo, include a July 18,2000,City of San Luis Obispo Council Agenda Report("Council Agenda Report") with two attachments: (1)Executive Summary of"Salinas Reservoir Expansion Project Dam Safety Evaluation" ("Executive Summary") and (2)July 5,2000,letter from San Luis Obispo's dam expansion consultant,URS Greiner Woodward Clyde,to San Luis Obispo's water division manager,Gary Henderson("URS Letter'). True and correct copies of the Council Agenda Report and the two attachments are enclosed herewith and marked as Paso Robles Exhibit 32. The Executive Summary of the Dam Safety Evaluation states that the results of the computer analysis indicate that for the case of the raised reservoir level, "the stresses induced in the dam by the Maximum Credible Earthquake on the Rinconada fault would be much greater than the strength of the concrete in many portions of the dam As such,the analyses indicate that the dam is not strong enough to withstand strong ground shaking with the increased load from a raised reservoir.

(Executive Summary,pp. 2-3.) The URS letter suggests two conceptual approaches for seismically strengthening Salinas Dam,each of which involves a major redesign of the proposed project and neither of which was discussed in the Salinas Reservoir Enlargement Project EIR. During the hearings on San Luis' extension petition, Paso Robles pointed out that San Luis Obispo improperly certified the FEIR before completing the necessary studies of structural and seismic safety issues. (Closing Brief of City of El Paso de Robles,pp. 33-34.) Documents in the Hearing Record established that final conclusions regarding seismic impacts were not yet drawn,and that the conclusion in section 3.2.3.2.2 at 3.2-20 of the FEIR that seismic impacts would be reduced to less than significant was premature. The newly recognized seismic problems and need to redesign the proposed project confirm that the EIR prepared for the project is legally inadequate to support Water Board approval. Pursuant to Public Resources Code section 21166,the new information produced by San Luis Obispo not only shows that the prior EIR is inadequate but triggers San Luis' duty to prepare a subsequent EM A subsequent EIR is required to disclose the previously unanalyzed significant seismic impact of the dam expansion project and to analyze the impacts resulting from the major redesign of the project that would be necessary to address this impact. The duty to prepare a subsequent EIR arises when any of the following three events occurs: (1) substantial changes are-proposed in the project which will require major revisions of the EIR; (2) substantial changes occur with respect to the circumstances under which the project is being undertaken which will require major revisions in the environmental impact report;or (3) new information,which was not known and could not have been known at the time the environmental impact report was certified as complete becomes available. Pub. Res. Code§21166. Although only one of these three events need occur to require preparation of a subsequent EIR,the new seismic and dam safety information would require preparation of a subsequent EIR under any of the three tests. John Brown, Hearing Officer August 15, 2000 Page 3 First, the new seismic analysis produced in June and July 2000 constitutes new information that was not known,and could not have been known when San Luis certified its EIR in 1998,and thus triggers Public Resources Code section 21166(c). San Luis even calls the new seismic data "new information." (See Council Agenda Report at 4.) CEQA Guideline section 15162 clarifies that the type of new information that triggers the requirement to prepare a subsequent EIR includes information showing that the project will have one or more significant effects not discussed in the previous EIR or showing that significant effects previously examined will be substantially more severe than shown in the previous EIR- The new information in Paso Robles Exhibit 32 shows that if the dam is expanded as San Luis proposes, it"would not be strong enough to withstand the design earthquake on the Rinconada fault." (Council Agenda Report at 4). Although previous seismic studies indicated that an expanded dam would be stable during the design earthquake,"current analyses show that the dam would not be strong enough to withstand the design earthquake." (Executive Summary at 3.) Accordingly, "[t]he dam with a raised reservoir level does not satisfy modem seismic performance evaluation criteria such as those currently used by DSOD." (Executive Summary at 5.)' This information establishes that the project as described in the FEIR will have significant seismic impacts not discussed in the FEIR and substantially more severe than acknowledged in the section of the FEIR dealing with seismicity and faulting. Second,the new data shows that earthquake forces acting on the dam are likely to be 70 percent greater than the forces previously assumed. (See Council Agenda Report.at 3;Executive Summary at 4-5.) The increase in the severity of the expected earthquake forces constitutes a substantial change in circumstances under which the project is being undertaken,triggering Public Resources Code section 21166(b). Third,the major new construction proposed to address the greater earthquake forces would transform the dam expansion project into something substantially different from the project proposed by San Luis and analyzed in its EIR. The EIR analyzed installation of drum gates at the dam's existing spillway, without any strengthening of the concrete arch dam structure. The new information shows that either the dam thickness must be substantially increased—an approach that might not be technically feasible—or a massive concrete buttress must be constructed to support the downstream side of the dam. (See Council Agenda Report at 3;June 30,2000,URS letter.) Either . approach constitutes a substantial change to San Luis'proposed project that would cause potentially significant adverse environmental impacts that require major revisions to the existing EIR,triggering Public Resources Code section 21166(a).) John Brown, Hearing Officer August 15,2000 Page 4 The URS Letter identifies a list of"CONS"for each approach to addressing the project's seismic safety problems. Building a massive concrete buttress would give the dam a "significantly different"appearance, (URS Letter at 4), which raises new aesthetic impact issues. Aggregate required to make the buttress concrete "can not be produced on site and will need to be imported", (id.),which raises new traffic and air quality issues. Building a buttress.would prevent installation of the proposed spillway drum gates,which"could restrict reservoir operation flexibility." (Id.) This raises questions about all resource impacts affected by the dam's proposed operational regime,including harm to downstream water users, like Paso Robles. None of these potential adverse environmental impacts have been analyzed and subjected to public review and comment, as required by CEQA. Accordingly, the Water Board may not lawfully approve the proposed project pursuant to CEQA unless and until San Luis Obispo prepares a subsequent EIR. Procedural Considerations The documents submitted as Paso Robles Exhibit 32 did not exist in October 1999,when the Water Board conducted three days of hearings on San Luis Obispo's petition. The Board adjourned the hearing on October 18, 1999, and the record was closed effective January 10,2000. (Transcript,October 18, 1999, at page 791,lines 22-23.) The seismic safety studies and project redesign options were not presented until June and July 2000. Thus,they could not have been brought to the Board's attention until now. Section 768 of the State Board's regulations allow a party to petition for reconsideration of an order of the Board where there is relevant evidence which, in the exercise of reasonable diligence,could not have been produced. Such relevant evidence should be admitted before the Board issues a decision,so that it can be taken into account in reaching a correct decision in the first place. The Council Agenda Report was prepared by San Luis Obispo's own staff,so it should come within one of the exceptions to the hearsay rule,including Evidence Code section 1220,admissions of a party. The URS Letter that San Luis' own staff attached to the Council Agenda Report also should come within one of the hearsay exceptions, such as Evidence Code section 1221,adopted admissions. The City of El Paso de Robles thus requests that the State Board reopen the record in the matter of the City of San Luis Obispo's Petition for Extension of Time and accept Paso Robles Exhibit 32 into evidence. Enclosed are 6 copies of the exhibit. Copies of this letter with the enclosure have been served on all parties. John Brown,Hearing Officer August 15, 2000 Page 5 Conclusion The State Board should reopen the record to admit the enclosed documents containing relevant new information about the seismic danger posed by San Luis'proposal to enlarge Salinas Reservoir. The new seismic analysis shows that the Salinas Reservoir Enlargement Project,as discussed in the FEIR . and presented during the hearings of October 1999,has.dam safety problems that threaten catastrophic failure in the event of a maximum credible earthquake. In light of these public safety problems and the failure of the FEIR to address them adequately,the State Board cannot approve the extension of time to permit construction of the reservoir enlargement project as proposed. Nor can the Board,or San Luis Obispo,approve an alternate design,until San Luis prepares a subsequent E1R disclosing the impacts of the project related to seismicity and faulting and addressing all impacts of any alternative design intended to address the seismic impacts.

Moss, Utilities Director Subject: Salinas Reservoir Expansion Project Approval and City of Paso Robles request for delay in action. The City Council will be considering formal approval of the Salinas Reservoir Expansion Project as Council agenda item #1 on November 9, 2000. This project approval under CEQA and filing of the subsequent Notice of Determination has been mandated upon the City by the State Water Resources Control Board to be completed no later than 5:00pm November 13, 2000. Failure to do so will result in the forfeiture of the City's rights to the expanded capacity of the Salinas Reservoir. The City of Paso Robles will be requesting that the City Council not approve the project as recommended, rather the City should petition the SWRCB for an extension of time relative to this condition and that Paso Robles would support such a request to the SWRCB. The purpose of the time extension would be to allow the City time to complete additional seismic engineering analysis and complete any additional environmental work as may be required. While we should accept this suggestion as an offer of cooperation by the city of Paso Robles, there is no mechanism to make such a requested time extension and doing so would result in the loss of our water rights. The Council may wish to assure Paso Robles representatives that the City has no.intention of completing a project that would not be seismically safe, and that should additional studies indicate that seismic reinforcement is necessary to such an extent as to require additional environmental review, the City will complete that review at that time. We wish to remain positive in our hopes for cooperation with the Paso Robles, however cannot at this time honor their request for delaying action on the project.

DISCUSSION The Salinas Dam was constructed in 1941/42 by the federal government to provide water for Camp San Luis Obispo and secondarily to provide water for the City of San Luis Obispo. The dam is a 135-foot high concrete arch-shaped facility which has a current maximum storage capacity of 23,843 acre feet. The facilities are under the control of the U.S. Army Corps of Engineers (Corps) but are operated by the San Luis Obispo County Flood Control and Water Conservation District.. Since the dam is federally owned, it does not currently fall under the jurisdiction of the State Division of Safety of Dams (DSOD). The City of San Luis Obispo has rights to all the water diverted from the reservoir under state water rights Permit 5882. The Corps.is also listed as a co-permittee on the water rights permit but no water is utilized for federal purposes. The City has proposed expanding the storage capacity of the reservoir for many years by installing 19-foot high spillway gates in the existing dam. With the installation of the gates, the storage capacity would be increased to 41,792 acre feet.with a resulting increase in safe annual yield of 1,650 acre feet. Since the dam no longer serves any federal purpose, the Corps has stipulated that prior to initiation of the Salinas Reservoir Expansion Project, the facility would have to be transferred to a local agency. In California, dams owned by local agencies are under the jurisdiction of the California Department of Water Resources, Division of Safety of Dams, and must meet current dam safety standards. As such, a dam safety evaluation has been performed to address dam safety issues, such as safety during earthquakes and flooding. Based on this requirement, the City contracted with URS (formerly Woodward-Clyde) to evaluate the safety of the dam considering the proposed reservoir expansion project and the ability of the dam structure to meet current state standards with the increased water storage. . S Salinas Reservoir Expansion Project—Dam Safety Evaluation Page 2 Previous Studies Woodward-Clyde Consultants completed an analysis of the feasibility of expanding the reservoir storage capacity in February 1989 (revised in December 1990). The study analyzed the seismic stability and the hydrology associated with the design flood flow event (Probable Maximum Flood). The analysis was based on design standards at the time and on an understanding.of local faults at that time. The analysis indicated that the dam expansion project could meet seismic standards with minor improvements to the facility. The analysis did indicate that the design flood would overtop the dam for both the existing condition and with the spillway gates installed. The flow over the dam could potentially erode the area at the base of the dam and therefore the report indicated that armoring (concrete) at the dam base would be necessary. Updated Studies The recently completed analysis for seismic loads and the flood flows associated with the Probable Maximum Flood (PMF) have been updated based on the current standards and DSOD requirements. Both the PMF and seismic loads have increased as discussed below. Probable Maximum Flood The PMF has been updated based on the new requirements which were issued in 1998. The current PMF rainfall event equates to 26.0" in 72 hours. The previous analysis was for 25.2" for 72 hours. With this increase in rainfall, the total flow into the reservoir will increase by about 2%_ The new analysis predicts that 108,000 acre feet would flow into the reservoir. This is an extremely large,amount of water and would fill the entire capacity of the existing reservoir 4'/z times. With these flows, the existing dam and the modified dam with spillway gates installed would be overtopped.. Therefore, armoring of the dam base is still recommended to prevent erosion in the unlikely event of a storm of this magnitude. Earthquake Event A number of faults have been identified which could potentially impact the Salinas Dam. These faults were evaluated to estimate which fault would generate the largest loads on the structure. The Rinconada fault, as in the previous analysis, was judged to be the controlling fault for seismic analysis. Seismic design criteria are updated as new earthquakes occur and our understanding of resulting seismic forces increases. An earthquake on the Rinconada fault is the controlling event (same as assumed in 1989), however, the earthquake forces that are predicted from a fault rupture have increased by approximately 70% for the reasons discussed_below. In 1989, the activity (historic movement) of the Rinconada fault was reviewed with respect to deciding if the fault was active and therefore capable of generating a damaging earthquake. The evidence was inconclusive, but to be conservative for the purposes of dam safety, the fault was assumed to be capable of generating a design earthquake. The ground motions from the earthquake were selected in the middle range of motions(for known active faults ground motions Salinas Reservoir Expansion Project—Dam Safety Evaluation Page 3 are selected towards the upper range, however, it was judged that a conservative assumption regarding the activity of the fault had already been made and that higher ground motions were judged to be overly conservative at that time). The Rinconada fault has three separate segments and the previous study assumed that a fault rupture would include up to 50% of the fault length. This assumption was consistent with design standards at that time. In 1992, an earthquake occurred near Landers, California which has resulted in revisions to seismic design for this project. The Landers earthquake occurred on a fault with three separate sections and demonstrated that a fault rupture could jump to several segments. The potential for multiple fault segment ruptures and additional evidence of fault activity have resulted in an increase of the assumed seismic loads by approximately 70% (0.65g to 1.10 g). This increase results in a significant increase in the potential seismic induced stresses in the dam. The structural computer analysis of the dam indicates that the existing dam (without the spillway gates) would be capable of withstanding the design earthquake and satisfies modem seismic performance evaluation criteria. The analysis also indicates that"the dam is not strong enough to withstand strong ground shaking with the increased load from a raised reservoir." Remedial measures will be necessary to strengthen the dam prior to installation of the spillway gates. Strengthening Alternatives There are two alternatives which could be utilized to strengthen the dam for the increased water storage. The two alternatives are discussed in more detail in Attachment 2 to this report The potentially least costly alternative would involve placement of an additional layer(about equal to the existing dam thickness) of concrete on the downstream face of the dam. While the costs may be less, there are questions concerning the "bond" strength between the existing concrete and the new concrete which may not be acceptable to DSOD. This method of strengthening has been approved by DSOD for a dam of this type in California, however, Salinas Dam has potentially greater seismic loading and therefore it may be difficult to receive approval. The estimated cost range for this alternative is $5.6 to $8.5 million which is in addition to other project related costs (i.e. spillway gate,recreation facilities relocation, environmental mitigations, etc.). The second alternative involves the placement of a"buttress"against the downstream face of the dam. The buttress would be constructed using "roller compacted concrete" (RCC) and would be a stepped wedge structure which would transform the current arch dam into a curved gravity structure. This method was successfully used on the Gilbraltar Dam near Santa Barbara to strengthen the existing concrete arch dam. This type of remedial strengthening measure has been used on a number of dams in California and has been accepted previously by DSOD, therefore this altemative would likely gain relatively easy approval from DSOD. The estimated cost for this alternative, excluding other project costs, would range between$7.2 and $11.0 million. Salinas Reservoir Expansion Project—Dam Safety Evaluation Page 4 Nest Steps The current draft dam safety evaluation report has not been submitted to the State Division of Safety of Dams or the U.S. Army Corps of Engineers for their review. The seismic design criteria for the structural analysis was presented to DSOD during development of the computer model. DSOD concurred with the criteria and assumptions to be used in the computer model runs. Following the presentation of the information to the City Council, staff will transmit the reports to DSOD and the Corps for their review and comment. The previously approved concrete core sampling component of the study has been placed on hold pending review of the analysis by the Corps and DSOD. The coring may not be necessary or may be reduced in scope based on review of this recent analysis by the state. Funding for the concrete coring and strength testing is currently included in the contract with URS. Based on this new information, staff will be preparing a thorough review and update of all the alternative water supply projects which could meet the city's projected future water supply deficit based on growth identified in the General Plan. In addition, the City is still waiting for a decision on our water rights permit hearing relative to increasing the storage capacity at Salinas Reservoir. Staff anticipates that a decision on the water rights permit should be received within the next several months. Staff will prepare the complete evaluation of water supply projects and strategies for Council consideration this fall. Summary The updated seismic evaluation of the Salinas Dam indicates that the existing facility meets current seismic design criteria. The analysis concludes that if the reservoir storage capacity were increased, the dam would .not be strong enough to withstand the design earthquake on the Rinconada fault. Remedial strengthening measures are available to safely allow the expansion of the reservoir to move forward, and would likely cost an additional $5.6 to $11.0. ATTACHMENTS 1.

Correspondence titled "Salinas Reservoir Expansion Project — Phase 1, Dam Engineering, Dam Strengthening Alternatives" On-File in Council Office: 1. Complete 2 Volume Report"Salinas Reservoir Expansion Project—Dam Safety Evaluation" Attachment 1 Salinas Reservoir Expansion Project Dam Safety Evaluation Executive Summary INTRODUCTION Salinas Dam is a 135400t high concrete arch-shaped dam, located in San Luis Obispo County on the Salinas River, about 9 miles southeast of the town of Santa Margarita, California. The reservoir at the dam is referred to as Santa Margarita Lake. The dam is owned by the US Army Corps of Engineers, and was constructed by the Corps between late 1941 through early 1942. The original purpose of the dam was to provide wartime water supply to Camp San Luis Obispo. The dam was constructed in accordance with the engineering standards of practice at the time, and visually appears to be in good shape. The County of San Luis Obispo currently operates the reservoir for the Corps of Engineers, to provide municipal water supply to the City of San Luis Obispo (City) and for recreation. The reservoir provides approximately 70 percent of the water supply to the City, and along with the Whale Rock Reservoir, is one of two surface water reservoirs providing water for the City's use. REASONS FOR STUDY The City is considering expanding the capacity of Santa Margarita Reservoir to meet the growth proposed in the City's General Plan. The current capacity of the reservoir of 23,840 acre-feet(af) would be increased by 17,950 of following completion of the expansion project The "safe yield"(the amount of water which would be available for use each year through a critical drought period) would increase by approximately 1650 acre-feet per year. A separate Environmental Impact Report has been prepared . describing the project, impacts from the project, and proposed mitigation measures. The layout of the dam includes a concrete-lined spillway channel on the north(right) side of the dam to convey flood flows past the dam. The crest elevation of the spillway(the spillway's highest location) is approximately 20 feet below the top of the dam. Therefore,to store additional water, spillway gates or other barriers would be installed at the spillway crest location. With the gates in place the reservoir level would be approximately 19 feet higher than currently exists when the reservoir is M. The dam would not be increased in height As part of the proposed reservoir expansion, dam ownership would be transferred from the Corps of Engineers to local control and the safety of the dam would therefore come under state jurisdiction. The California,Department of Water Resources, Division of Safety of Dams(DSOD) is responsible for dam safety for all jurisdictional non-federal dams in California. The DSOD takes a careful and stringent review of dam safety, _ because the consequences of the failure of a dam can be considerable. They have developed general guidelines for use in assessing dam safety during an earthquake or flood. Executive Summary Attachment 1 Page 2 of 5 Under an agreement (dated 1999) with the City of San Luis Obispo, URS Greiner Woodward Clyde conducted a study to update the previously performed engineering feasibility of increasing the storage capacity of Salinas Reservoir. The engineering studies addressed both the seismic and hydrologic consequences of raising the reservoir. The criteria for this current evaluation are based upon meeting DSOD dam safety requirements. STABILITY OF THE DAM DURING EARTHQUAKE Information Used in the Stability Evaluation of the Dam A comprehensive evaluation of the stability of the dam during an earthquake was performed using a computer model of the dam. This stability evaluation was performed for the dam with the proposed higher water level, as well as for the dam with the existing reservoir level. In order to evaluate the stability of the dam during an earthquake, several key pieces of information were developed. This information includes the following. • The location of the nearest active faults. An active fault is currently defined by the Division of Safety of Dams to show evidence of earthquakes occurring on them in the past 35,000 years. Faults with inconclusive evidence of activity, or that cannot be shown to be inactive, are treated as being active for the purposes of the evaluation of dam safety. • The size(or magnitude) of the largest earthquake that could occur on these faults. This largest earthquake is referred to as the Maximum Credible Earthquake (MCE), and is the largest earthquake that is thought possible to occur on that fault. The MCE is the"design earthquake." • The amount of ground shaking at the dam from the design earthquake. The larger the size or magnitude of the earthquake, and the closer the fault is to the dam,the greater the ground shaking will be at the dam. The results of the evaluation concluded that the closest and most significant active fault is the Rinconada fault, located about one mile to the west, close to Pozo Road. The design earthquake that could be generated on this fault is a magnitude 7-'/�,which is a large earthquake. As an example, the Magnitude 6.8 1989 Loma Prieta earthquake caused significant damage in San Francisco, and it occurred about 60 miles away from San Francisco. The combination of such a large earthquake located so close to the dam results in very strong ground shaking at the dam. The performance of the dam under this strong shaking was analyzed for the current and proposed raised reservoir levels using a computer model that estimates the stresses in the dam caused by the earthquake. The stresses were then compared with the strength of the concrete of the dam An assessment was made whether the dam will maintain sufficient integrity to prevent the sudden release of the reservoir. Stability of the Dam with the Raised Reservoir Level The results of the computer analysis indicate that for the case of the raised reservoir level, the stresses induced in the dam by the Maximum Credible Earthquake on the Rinconada c\windows\desktop\exec summary-revised draft rpt version.doe 07/10/00 9:48 AM Executive Summary Attachment 1 Page 3 of 5 fault would be much greater than the strength of the concrete in many portions of the dam. As such,the analyses indicate that the dam is not strong enough to withstand strong ground shaking with the increased load from a raised reservoir. The dam, under the proposed reservoir raise, does not satisfy modem seismic performance evaluation criteria such as those currently used by DSOD. Stability of the Dam with the Current Reservoir Level The computer analyses were also completed for the dam with the reservoir at its current maximum level. The analysis indicated that stresses could exceed the strength of the concrete at some locations of the dam, but with very short time durations. As such, the overall stress levels and distribution were found to remain within an acceptable range relative to the safety of the dam. The dam, under the existing maximum reservoir level, satisfies modern seismic performance evaluation criteria such as those currently used by DSOD. Comparison with 1990 Analyses The results of previous analyses (completed in 1990) indicated that the dam, with the maximum reservoir level raised by 19.3 feet, would be stable during the design earthquake. The current analyses show that the dam would not be strong enough to withstand the design earthquake. The reasons for this difference are largely due to the differences in estimations of earthquake ground motions used in the analyses, details of which are discussed below. A previous seismic hazard analysis was performed by Woodward Clyde Consultants for Salinas Dam in 1988 (submitted to the City in the 1989 Interim and 1990 Revised Report). Iii this report, an MCE of magnitude (Ms) 7.4 resulting from an earthquake on the Rinconada fault at a distance of about one mile was selected. This evaluation was based solely on available data and no field investigations were performed. An earlier study by the Corps of Engineers in 1977 concluded that the Rinconada fault was not active based on two trenches excavated across the fault. Thus the judgment that the fault was active in the 1988 study was conservative and was based principally on recording of seismicity in the vicinity of the fault As stated in the 1990 report,very little seismologic and geologic information is available on the Rinconada fault Considering the above,a median (or 50%percentile)peak horizontal acceleration of 0.65g was selected. This approach was judged to be consistent with DSOD procedures based on the information known at that time. In this current evaluation of Salinas Dam,an analysis of aerial photographs and a field reconnaissance was performed along portions of the Rinconada fault The analysis found evidence of active faulting. In addition, the fault consists of three segments, and previous assessments of the fault included that up to 50% of the fault length could rupture during an earthquake.' However,the Landers earthquake (Magnitude 7.3, 1992)showed that fault rupture could jump to several segments. Therefore,the likelihood of an earthquake occurring close to the dam was increased from the 1990 study. Considering this finding, a more conservative ground motion (mean + 1, or 84rh percentile)of 1.l Og (which is 70% c:lwindows\desktoplexec summary-revised draft rpt version.doc 07/10/00 9:48 AM Executive Summary Attachment 1 Page 4 of 5 h greater than the 1990 value of 0.65g) was selected for use in the analysis. Based on the updated information, it was judged that DSOD requires use of these higher seismic values. STABILITY OF THE DAM DURING FLOODING Standardized procedures are used to estimate the maximum amount of flooding which could occur at a dam. The most recent National Oceanic and Atmospheric Administration (NOAA) guidelines(referred to as HMR No. 58,published in 1998) were used to estimate probable maximum amount of rainfall that could occur over the Santa Margarita Lake watershed. The amount of rainfall was then used to calculate the design flood, referred to as the Probable Maximum Flood, or PMF. The computer model was used to check the stability of the dam with higher reservoir loads during the design flood. It was found that the dam could safely withstand the design flood under the raised reservoir scenario. For both-the existing maximum reservoir and the proposed raised reservoir level,the PMF would overtop the dam. With the raised reservoir, overtopping flow would be greater and occur over a longer duration compared to the current maximum reservoir level. The overtopping would not damage the dam itself,however, the rock at the base of the dam could be eroded. This erosion could lead to undermining of the dam foundation, which could lead to damage to the dam. Methods to prevent erosion damage from occurring are relatively simple, and include placing reinforced concrete at the areas where erosion could occur. RIGHT ABUTMENT STABILITY During the construction of the dam, measures were incorporated in the design to strengthen the rock mass on the right abutment, which was thought to be prone to movement during an earthquake. The DSOD has asked that the stability of the rock foundation at the right side of the dam be evaluated. Based on our evaluation of the data, our analysis results indicate that the rock mass is stable. COORDINATION WITH THE DIVISION OF SAFETY OF DAMS AND THE CORPS OF ENGINEERS Very good coordination and understanding of the project has been developed with the DSOD and the Corps of Engineers. Meetings have been held with the DSOD, Corps of Engineers, City and County to discuss dam safety issues. As part of the study, an interim report was prepared and submitted to DSOD in November 1999. The purpose of the document was to present basic analysis parameters and evaluation criteria proposed for use in the seismic analysis evaluation of Salinas Dam. In February 2000, DSOD sent a letter to the City confirming that the earthquake ground motions proposed for use in the analyses were satisfactory. POTENTIAL DAM STRENGTHENING MEASURES TO ALLOW RAISE IN MAXIMUM RESERVOIR LEVEL Remedial construction has been performed on a number of concrete dams in the U.S. in recent years to strengthen them to resist damage from strong earthquakes. On the basis of our own experience in the design of strengthening measures for concrete arch dams in c:\windows\desktop\exec summary-revised draft rpt version.doc 07/10/00 9:48 AM Executive Summary Attachment 1 Page 5 of 5 California (such as the 190-foot high Gibraltar Dam near Santa Barbara), the most straight-forward approach to strengthen the Salinas Dam would be to place a concrete buttress against the downstream face of the dam. This would"stiffen" the dam, and result in satisfactory stability of the dam. This approach could be combined with construction of a concrete barrier in the spillway, which would eliminate the need for the spillway gates and reduce overall construction costs. Another approach, which would result in less ground disturbance, would be to thicken the arch by placing additional concrete on the downstream face of the dam to stiffen the arch shell and improve its overall stability. We are considering this approach for a 100-foot high arch dam in California. An additional analysis was performed as part of our work to evaluate this strengthening concept considering a modified dam with an overall average concrete thickness which is approximately double that of the existing dam. The results of this analysis indicate that this approach would be technically feasible providing that a high quality bond can be achieved between the new and existing concrete. The actual required thickness of additional concrete would depend on a number of factors including constructibility-related considerations. However, although this approach may not be appropriate for Salinas Dam because of the site-specific factors such as strong groundshaking,it is recommended that its viability be reviewed in more detail at an appropriate time. In summary, there are a number of options that can be considered for strengthening the dam. The overall cost,technical feasibility and environmental feasibility will govern the feasibility of these options. SUMMARY AND CONCLUSIONS • The dam with a raised reservoir level does not satisfy modem seismic performance evaluation criteria such as those currently used by DSOD. • There are a number of options that can be considered for strengthening the dam. The overall cost,technical feasibility and environmental feasibility will govern the feasibility of these options. • The dam with the existing maximum reservoir level satisfies modem seismic performance evaluation criteria such as those currently used by DSOD. • The design flood will overtop the dam for the existing and raised reservoir cases,but can be safely remediated by relatively easy methods. • The dam can safely withstand the probable maximum flood(PMF) loading under the raised reservoir scenario. • Whether the reservoir is raised or not, it is recommended that the areas that could be damaged by overtopping during the design flood leading to erosion be covered with a suitably designed concrete blanket. c:\windows\desktop\exec summary-revised draft rpt version.doc 07/10/00 9:48 AM URS July 5, 2000 Project No: 66-099SB037.02 Mr..Gary Henderson, Water Division Manager City of San Luis Obispo 955 Morro Street San Luis Obispo, CA 93401 Subject: Salinas Reservoir Expansion Project-Phase 1, Dam Engineering Dam Strengthening Alternatives Dear Mr. Henderson: In accordance with your request, we are pleased to provide you with two conceptual approaches, along with ballpark cost estimates, for seismically strengthening Salinas Dam. These approaches are based on a 19-foot increase in the maximum reservoir level. Remedial construction has been performed on a number of concrete dams in the U.S. in recent years to strengthen them for critical seismic loading conditions. Our proposed strengthening approaches were developed on the basis of our experience in the design of strengthening measures for concrete arch dams in California under the California Department.of Water Resources, Division of Safety of Dams (DSOD)jurisdiction. As such, the most straightforward and effective method of strengthening Salinas Dam would be to construct a roller-compacted concrete(RCC) buttress against the downstream face of the dam. This approach has been successfully implemented on several arch dams in California_ The addition of a buttress would change the thin arch dam into a gravity structure. A second approach would be to thicken the arch by placing additional concrete on the downstream face of the dam. The dam thickening would "stiffen" the arch shell and thereby increase its structural capacity during an earthquake. Very preliminary analysis indicates that this approach would be technically feasible providing that adequate shear transfer capacity can be achieved between the new RCC materials and the existing concrete. This letter report presents a description of these two strengthening approaches, referred to herein as "RCC Buttress" and "Arch Thickening". The description includes precedent, design features, and relative advantages and disadvantages of each approach. Ballpark cost estimates are included for use in feasibility and planning studies. Please note that: • Both approaches are based on downstream additions so as to maintain the reservoir in operation during the construction. • Both approaches are based on methods accepted, or under favorable review, from DSOD. URS Corporation 500 12th Street.Suite 200 Oakland.CA 94607-4014 Tel:510.893.3600 Faz: 510.874.3268 URS Mr.Cary Henderson City of San Luis Obispo June 30,2000 Page 2 of 8 RCC BUTTRESS CONCEPT The roller-compacted-concrete(RCC) alternative involves construction of an RCC buttress against the downstream face of the existing dam. The objective of this design is to change the dynamic response of the dam and thus reduce the dynamic stresses induced in the dam under earthquake loading. The addition of the RCC buttress transforms the current arch dam into a curved gravity structure. PRECEDENT RCC has been used for structural upgrades of several concrete arch and multiple arch dams in California as well as in other States. In nearly all cases the need for upgrading has involved strengthening to address seismic loadings substantially higher than originally designed for. The use of an RCC buttress for arch dam rehabilitation and strengthening has gained general acceptance from Federal and State regulatory agencies in general and from DSOD in particular. Two arch dams strengthened using an RCC buttress and which are most similar to Salinas Dam are Gibraltar Dam in California and Santa Cruz Dam in New Mexico. Both of these dams are larger than Salinas Dam (195- feet and 151-feet maximum height respectively) although both are single curvature thick arch structures whereas Salinas Dam is a double curvature thin arch structure. The significance of this difference is discussed below. Gibraltar Dam came under the jurisdiction and both FERC and DSOD accepted the design. Construction of Gibraltar Dam was completed in 1991 and at Santa Cruz Dam in 1990. Recent examples of multiple arch dams in California strengthened using a downstream buttress include Littlerock Dam in Palmdale, and Bear Valley Dam in San Bernardino County. In addition, URS is currently finalizing the design of a partial height RCC.buttress at Weber Dam, a 3-bay arch dam in the Sierra foothills east of Sacramento. CONCEPT FEATURES The layout of the buttress section would be accomplished using conventional design methods for concrete dams such as those used by the U.S.Bureau of Reclamation and the U.S. Army Corps of Engineers. The layout was conservatively assumed, based upon stability and constructability considerations, and no analyses were performed. For the purposes of estimating cost, the buttress section is assumed to extend the full height of the overflow section of the arch. During preliminary design the possible use of a partial height buttress could be investigated, which if feasible would significantly reduce construction costs. Conceptual designs of the various components of the design include the following: 1. A minimum crest width of 20 feet to facilitate construction. This provides the minimum width for construction equipment to place, spread and compact the RCC at the top of the buttress section. 07/03/00 X:VAwtonNstrcngtbcning.doc URS W Cary Henderson City of San Luis Obispo June 30,2000 Page 3 of 8 2. A downstream slope of 0.711: 1.OV based upon previous design experience and on the use of a formed downstream face. An unfaced downstream face will be limited to the angle of repose of the RCC materials which would result in an upstream slope closer to 0.8H: 1.OV. 3. The downstream face will be designed as a stepped spillway. The surface of the steps will be conventional concrete that would be placed concurrent with the RCC placement. The steps act as roughness elements creating turbulence and entraining air in the flood flows in order to dissipate energy and minimize flow accelerations and terminal velocity. With reduced energy and lower flow velocity at the toe of the buttress, the erosive power of the floodwater is substantially reduced and the need for extensive erosion protection of the bedrock can be eliminated. Two-foot high steps are proposed as a compromise between hydraulic efficiency and ease of construction. 4. A drainage gallery will be included within the buttress. Drain holes for relief of foundation pore pressures will be installed from the gallery and used to reduce the amount of uplift acting on the base of the buttress. The gallery would also serve as access for post construction inspection and, if required, foundation grouting. 5. The buttress could extend across the spillway, thus eliminating the need for spillway gates, and leading to some overall reductions in cost. PROS AND CONS PROS 1. Provides the most positive strengthening for-the dam. Curved gravity dams are extremely resistant to structural failure and have performed well during seismic shaking. This concept would remove any possible argument.that could be made as to the seismic stability of the dam under the raised reservoir condition. 2. The RCC buttress-strengthening concept is accepted by DSOD. 3. There are several precedents to the use of an RCC buttress in California to seismically strengthen arch or multiple-arch dams. 4. Can readily accommodate a future raise. 5. Eliminates the need for the erosion protection slab on the abutments and in the channel beneath the arch crest. The use of a stepped downstream face as a secondary or auxiliary spillway dissipates much of the energy in the overtopping flows. 6. Any potential problems associated with the adverse structural geology on the right abutment are not a significant factor in the stability of a curved gravity structure. 7. Eliminates the need for spillway gates, which would remove the cost of gates from the total construction cost estimate. 07/05/00 X:\Lawtonlstrengthating.doc URS Mr.Gary Henderson City of San Luis Obispo June 30,2000 Page 4 of 8 CONS 1. The appearance of the facility, while pleasing, will be significantly different. 2. The extent of the buttress needs to be reviewed considering project description and other aspects of the EIR. 3. The overhanging or negatively sloping downstream face will restrict how close construction equipment can come to the face of the arch resulting in use of more conventional (i.e. expensive) "interface concrete" (ie, concrete placed between the overhang of the existing dam, and the new RCC) than would otherwise be necessary. This was not an issue at either Gibraltar dam or Santa Cruz Dams, which have positively sloping downstream faces. 4. Aggregate for the RCC can not be produced on site and will need to be imported (the Santa Margirita"Hansen" quarry is relatively close). 5. No spillway gate could restrict reservoir operational flexibility, although the intended operational approach is to operate the reservoir with the gates always maintaining a full reservoir. COST ESTIMATE A conceptual-level estimate of the cost of construction of the RCC alternative is presented in Table 2. The estimated construction cost, in 2000 dollars, is $8.7 million. Quantities and unit prices shown in Table 2 may change, and the number of work items will increase, as design work progresses and the required work becomes better defined. Consequently the conceptual level estimate should be considered to have a range of minus 15 percent to plus 30 percent, which equates to a range of$7.4 million to $11.3 million. The estimates do not include design or construction management costs, nor do they include the spillway related costs associated with raising the reservoir level. Potentially the three biggest factors affecting the cost are: 1. Price and availability of imported aggregate rock. The unit price for producing RCC shown in Table 2 is based on importing aggregate rather than producing it on site. A moderate haul distance(10 miles) and an approximate cost for 1'h aggregate(from Hansen Aggregates) were assumed in assessing a unit price. However, Hansen Aggregate's quarry in Santa Margirita only produces a 1'/2 x% aggregate which is too clean for RCC production. Their crushing plant and screens would need to be modified to produce aggregate with a substantially higher fines content. A conservative mix design comprising 200 pounds of cement and 100 pounds of pozzolan per cubic yard of RCC was assumed. - 2. Site Logistics. Having sufficient area available close to the dam in which to set up a batch plant and for aggregate storage. The cost of in-place RCC will increase substantially if off site production of RCC is necessary. The estimated cost is based 07/05/00 X.UAWtonstrrngthening.doe URS Mr.Gary Henderson City of San Luis Obispo June 30,2000 Page 5 of 8 on being able to set up a batch plant immediately downstream of the dam: Space would have to be created immediately adjacent to the outlet control building, along with use of space at the intersection of the access roads to the toe of the dam and the top of the right abutment. A more detailed analysis is needed to properly evaluate construction logistics. 3. Access to the dam. Transporting the RCC from the batch plant to the buttress can be accomplished by a variety of methods including using trucks, a conveyor belt or lifting with cranes. Access for construction equipment and RCC on to the buttress is restricted on the right abutment by the spillway and on the left abutment by the step topography. The spillway must remain serviceable during construction, effectively limiting vehicular access from the right abutment. The environmental impacts (and economics) associated with cutting haul roads at various elevations on the steep topography of the left abutment may effectively rule out the use'of haul trucks to transport the RCC. Such access restrictions may lead to the use of commonly used conveyor systems. If use of neither conveyors nor trucks proves feasible, the RCC could be placed by crane(tower crane or cable) although the setup cost and slow production rate would increase placement cost. The estimated cost is based on being able to use either a conveyor belt system or haul trucks. Allowances were made for water management downstream of the worksite during construction and for relatively minor modifications to the existing outlet system to incorporate it into the buttress. However, the extent of these items is not defined at a conceptual level and these may substantially impact the final cost. An allowance for unlisted and unidentified items, equal to 25% of the subtotal, was made. For review purposes, we compared the total unit cost(estimated total cost divided by the volume of RCC) for a Salinas Dam buttress with costs for some recent RCC projects, in order to assess the reasonableness of our conceptual estimate. The comparison summary is presented in Table 3. The comparison projects include both new construction and rehabilitation of embankment and concrete gravity dams. • The costs(except for Weber which is still in design) are an average of the bids received (ignoring extreme numbers) including the engineers estimate. • None of the projects(except again for Weber Dam, which includes extensive outlet works modification) have any unusual features that would distort the unit costs. • The unit cost for Salinas is approximately$190 per cubic yard, which places it at the low end of the$260 to $300 plus range for the four rehabilitation projects. These four projects are however much smaller than Salinas and the lower unit cost for Salinas reflects economies of scale. 07/05/00 XAL&vAonlstrmgthening.doe URS Mr.Gary Henderson City of San Luis Obispo June 30,2000 Page 6 of 8 • Furthermore, the cost of the RCC and facingrnterface concrete in the Salinas estimate is approximately 50% of the total projected cost, which is in line with the proportions reported by Hansen and Reinhardt (Roller Compacted Concrete Dams,199 1) ARCH THICKENING CONCEPT This.alternative consists of thickening the dam on the downstream side. The thickened dam would have moderately increased stiffness and rigidity(relative to a buttressed dam), which would reduce the fundamental period of the dam, thereby increasing the dynamic response. However, the stresses generated within the dam would be reduced from their current levels since a larger structural section is resisting the dynamic forces. Preliminary analyses using the finite element model of the dam indicate that thickening is technically effective at reducing stresses to levels that satisfy modem seismic performance evaluation criteria. PRECEDENT The concept is currently in the final design phase for the seismic upgrading of San Clemente Dam, a gravity arch dam located in Monterey County. San Clemente is under, the jurisdiction ofDSOD, and the State has worked closely with URS in implementing its design. There are examples of concrete-gravity and masonry-gravity dams being raised by placing mass concrete against the downstream face. However, in the majority of instances the dams were designed to accommodate such a modification by incorporating a stepped face in the original design to facilitate shear transfer with the overlay concrete. DESIGN FEATURES The approach involves placing conventional concrete against the downstream face of the dam to increase the structural capacity of the arch. The thickness of the new concrete would be approximately the same as the original thickness at each elevation and location along the dam profile (ie, the thickness of the dam would double). With the reservoir elevation raised by the proposed 19 feet, our preliminary analyses indicate that to avoid excessive overstressing of the during the MCE (on the Rinconada fault based on 8e percentile motions), the thickness of the arch portion of the dam would need to be approximately doubled. For dynamic stresses to be reduced to acceptable levels, sufficient shear transfer must be achieved between the new and existing concrete in order to produce a monolithic section. - 07105YOO x:V awtonlstreogthating.doc \\ URS Mr.Gary Henderson City of San Luis Obispo June 30,2000 Page 7 of S PROS AND CONS PROS 1. The appearance of the dam would not be substantially altered. 2. The footprint of the strengthened dam would remain within the area of disturbance identified in the EIR CONS 1. The option is not feasible if the reliable shear strength provided by concrete-to- concrete bond is insufficient to resist shear stresses generated along the interface. Unless the generated shear stresses are low, as may be the case with a thin overlay, providing adequate shear strength is generally not possible using the concrete-to- concrete bond strength. Extracting the interface shear stresses from the computer model of the thickened dam is not straightforward and was not done as part of this work. Typically, a stepped pattern on the interface is necessary to act as shear keys in order to achieve a reliable shear transfer mechanism. However, a stepped face is only achievable if the dam is constructed that way to, for instance, allow thickening to occur as part of a future dam raise. 2. If concrete bond (i.e. adhesion) is found to provide adequate shear strength,the surface of the existing concrete must be very carefully prepared. Adequate surface preparation is very sensitive to quality control exercised during construction. The bond strength achieved is markedly degraded if specified procedures are not precisely followed. 3. The preliminary analyses did not address the impact that doubling the mass of the arch may have on the effectiveness and stability of the thrust blocks, particularly on the right abutment. 4. The anchored concrete slab over the bedrock surface downstream of arch will still be necessary to prevent the dam from being undercut by flood flows overtopping the dam crest. 5. There is minimal precedent for this type of strengthening. COST ESTIMATE The cost estimate for the arch thickening is very conceptual, and is.based on the assumption that the required bond strength can be developed and that the quantity of additional concrete (or the thickness of the additional concrete) is approximately equal to the quantity of the existing concrete. 07/05100 X;%1A Aon\streagth=ing.doo URS Mr.Cary Henderson City of San Luis Obispo June 30,2000 Page 8 of 8 Assuming the technical and design issues can be satisfactorily resolved, a ball-park estimate of the cost of construction of the arch thickening alternative is $6.5 million. The estimate should be considered to have a range of minus 15 percent to plus 30 percent, which equates to a range of$5.6 million to $8.5 million. The estimate do not include design or construction management costs, nor does it include the spillway related costs associated with raising the reservoir level. SUNEVIARY Although the cost estimate for the arch thickening approach is lower compared to the buttress approach, the buttress approach is recommended for the following reasons: ❑ It is well accepted by the DSOD based on our recent design practice; ❑ The arch thickening concept, while appropriate for dams with relatively small seismic loading, my not be appropriate for the Salinas Dam project because of the relatively high seismic loading. We would be glad to discuss these concepts with you in further detail at your convenience. Very truly yours, URS GREINER WOODWARD CLYDE Gd M.

This request is based on new information showing that the seismic and dam Z c o¢�i safety impacts of the reservoir expansion will be significantly more severe than o<0 1=�s� shown in the original EIR for the project. This new dam safety information was p7 Lid 01 prepared by San Luis Obispo's engineering consultant,URS Greiner Woodward Clyde, after the original EIR was certified in 1998. The new dam safety analysis concludes that if the storage capacity of Salinas Reservoir were increased, the existing Salinas Dam would not be strong enough to withstand the design earthquake on the Rinconada fault. In other words, the new studies conclude that the project, as originally designed and proposed,cannot be built without risking catastrophic dam failure. A copy of Volumes I and II of the Salinas Reservoir Expansion Project Dam Safety Evaluation Final Report prepared for the City of San Luis Obispo by URS Greiner Woodward Clyde is enclosed with this letter. Documents summarizing this new dam failure analysis and describing project redesign options were presented to the City Council in the July 18,2000,City of San Luis Obispo Council Agenda Report ("Council Agenda Report"). The agenda packet contained two attachments: (1) Executive Summary of"Salinas Reservoir Expansion Project Dam Safety Evaluation" ("Executive Summary") and (2)July 5, 2000, letter from San Luis Obispo's dam expansion consultant,URS Greiner Woodward Clyde, to San Luis Obispo's water division manager, Gary VUBA CITY OFFICE 422 CENTURY PARK DRIVE.SUITE A BAY AREA OFFICE PO.BOK Y76 1999 HARRISON STREET,SUITE 1300 YUBA CITY. LIFORNIA 98992-0776 OAKLAND.CALIFORNIA 94612 TELEPHONE:(830)674-9761 TELEPHONE:(510)E73-0760 FACSIMILE:(530)671-0990 FACSIMILE:(BIO)039-9104 City Council City of San Luis Obispo October 20, 2000 Page 2 Henderson ("URS Letter"). Copies of these documents are enclosed with this letter. The Executive Summary of the Dam Safety Evaluation states that the results of the computer analysis indicate that for the case of the raised reservoir level, "the stresses induced in the dam by the Maximum Credible Earthquake on the Rinconada fault would be much greater than the strength of the concrete in many portions of the dam. As such, the analyses indicate that the dam is not strong enough to withstand strong ground shaking with the increased load from a raised reservoir. The dam, under the proposed reservoir raise,does not satisfy modern seismic performance evaluation criteria such as those currently used by DSOD [Division of Safety of Dams]." (Executive Summary, pp. 2-3 (emphasis added).) The URS letter suggests two conceptual approaches for seismically strengthening Salinas Dam, each of which involves a major redesign of the proposed project and neither of which was discussed in the Salinas Reservoir Enlargement Project EIR. This new information requires preparation of a subsequent EIR under the California Environmental Quality Act ("CEQA"). Public Resources Code section 21166 and State CEQA Guidelines section 15162 provide that a subsequent EIR must be prepared when any of the following three events occurs: (1) new information,which was not known and could not have been known at the time the environmental impact report was certified as complete becomes available. (2) substantial changes occur with respect to the circumstances under which the project is being undertaken which will require major revisions in the environmental impact report; or (3) substantial changes are proposed in the project which will require major revisions of the EIR; Pub. Res. Code § 21166. Although only one of these three events need occur to require preparation of a subsequent EIR, the new seismic and dam safety analysis produced by San Luis's engineering consultant requires preparation of a subsequent EIR under all three tests. First, the seismic and dam safety analysis produced in June and July 2000 constitutes new information that was not known,and could not have been known, when San Luis certified its EIR in 1998, and thus triggers Public City Council City of San Luis Obispo October 20,2000 Page 3 Resources Code section 21166(c). The Agenda Report even calls the new seismic data "new information." (See Council Agenda Report at 4.) CEQA Guideline section 15162 clarifies that the type of new information that triggers the requirement to prepare a subsequent EIR includes information showing that the project will have one or more significant effects not discussed in the previous EIR or showing that significant effects previously examined will be substantially more severe than shown in the previous EIR. The new information shows that if the dam is expanded as San Luis proposes, it "would not be strong enough to withstand the design earthquake on the Rinconada fault." (Council Agenda Report at 4). Although previous seismic studies indicated that an expanded dam would be stable during the design earthquake, "current analyses show that the dam would not be strong enough to withstand the design earthquake." (Executive Summary at 3.) Accordingly, "[t]he dam with a raised reservoir level does not satisfy modern seismic performance evaluation criteria such as those currently used by DSOD." (Executive Summary at 5.) This information establishes that the project as described in the FEIR will have significant seismic impacts not discussed in the FEIR and substantially more severe than acknowledged in the section of the FEIR dealing with seismicity and faulting. Second, the new data shows that earthquake forces acting on the dam are likely to be 70 percent greater than the forces previously assumed. (See Council Agenda Report at 3; Executive Summary at 4-5.) The increase in the severity of the expected earthquake forces constitutes a substantial change in circumstances under which the project is being undertaken, triggering Public Resources Code section 21166(b). Third, the major new construction proposed to address the greater earthquake forces would transform the dam expansion project into something substantially different from the project proposed by San Luis and analyzed in its EIR. The EIR analyzed installation of drum gates at the dam's existing spillway, without any strengthening of the concrete arch dam structure. The new information shows that either the dam thickness must be substantially increased—an approach that might not be technically feasible—or a massive concrete buttress must be constructed to support the downstream side of the dam. (See Council Agenda Report at 3;June 30, 2000, URS letter.) Either approach constitutes a substantial change to San Luis' proposed project that would cause potentially significant adverse environmental impacts that require major revisions to the existing EIR, triggering Public Resources Code section 21166(a).) City Council City of San Luis Obispo October 20, 2000 Page 4 The URS-Letter identifies a list of"CONS" for each approach to addressing the project's seismic safety problems. Building a massive concrete buttress would give the dam a "significantly different" appearance, (URS Letter at 4), which raises new aesthetic impact issues. Aggregate required to make the buttress concrete"can not be produced on site and will need to be imported", (id.), which raises new traffic and air quality issues. Building a buttress would prevent installation of the proposed spillway drum gates, which "could restrict reservoir operation flexibility." (Id.) This raises questions about all resource impacts affected by the dam's proposed operational regime, including harm to downstream water users, like Paso Robles. None of these potential adverse environmental impacts have been analyzed and subjected to public review and comment, as required by CEQA. A subsequent EIR is necessary under CEQA to present the new dam failure analysis, to describe the recommended alternatives for redesigning the dam expansion project to address the threat of catastrophic failure, to analyze the potential environmental impacts of the alternative project designs and to prescribe mitigation measures to avoid or reduce impacts. Only if the City of San Luis Obispo prepares a subsequent EIR containing this information will the public, other government agencies with authority to approve the project and the City Council, itself,have the information needed to understand the public safety and environmental consequences of approving a dam expansion project. Just last month, in a case involving the State Water Project,Planning and Conservation League v. Department of Water Resources, 83 Cal. App. 4th 892 (2000), the court of appeal stated: "The ultimate decision of whether to approve a. project,be that decision right or wrong, is a nullity if based upon an EIR that does not provide the decision-makers, and the public, with the information about the project that is required by CEQA." Id. at 916. The error is prejudicial "if the failure to include relevant information precludes informed decision-making and informed public participation, thereby thwarting the statutory goals of the EIR process." Id. The court referred to the "essential mission of CEQA to present a full disclosure of the potential environmental impacts of the proposal." Id. Any decision by the City Council to approve the proposed dam expansion project without first disclosing important information regarding seismic impacts and dam safety in a subsequent EIR would jeopardize public safety and violate CEQA. San Luis Obispo may not lawfully approve the proposed Salinas Dam Expansion Project unless and until the City prepares a subsequent EIR. But even more important—the City of El Paso de Robles and other communities lie downstream of Salinas Dam. And there is no possible justification for the elected public servants on San Luis Obispo's City Council to approve a water supply City Council City of San Luis Obispo October 20,2000 Page 5 expansion project based on a design that threatens downstream communities with catastrophic loss of life and property damage from dam failure. The duty to avoid catastrophic dam failure must overcome the desire to support new growth and development by expanding the water supply from Salinas Reservoir. Conclusion The new seismic analysis shows that the Salinas Reservoir Enlargement Project, as described and analyzed in the original FEIR,has dam safety problems and would risk dam failure in the event of a maximum credible earthquake. The Salinas Reservoir expansion, as proposed, will not meet the standards of the Division of Safety of Dams. This is an important impact—it involves the potential for catastrophic downstream flooding. In light of these public safety problems, the City Council must not approve construction of the reservoir enlargement project as proposed. Nor can the City of San Luis Obispo approve an alternate design, until it prepares a subsequent EIR disclosing the true impacts of the project related to seismicity and faulting and addressing all impacts of any alternative design intended to address the seismic impacts. Finally, the City of El Paso de Robles requests that San Luis Obispo notify Paso Robles of any upcoming City Council meeting at which the Salinas Reservoir Expansion Project will be considered as an action item.
