They provided the data for the preparation of the Draft EIR which included a list of 10 mitigation measures that could be used to reduce the impact of the project to the less.than significant level. Comments have been received on the Draft EIR and on the proposed mitigation measures. It is now necessary to develop a complete mitigation and monitoring plan to include in the Final EIR. As part of the mid-year review on February 27, 1996, the Council approved an additional appropriation of $75,000.00 for the study phase of the Water Reuse Project. This included $35,000.00 needed to have Fugro complete the mitigation plan in sufficient detail to process the Final EIR. The attached Addendum for an amount not to exceed $18,903.00 proposes to complete the work needed to satisfy the requirements of the CEQA process. After the completion of this work, the mitigation plan will include a list of mitigation measures and locations where these should be implemented. After the EIR is certified and the State Water Resources Control Board has issued the necessary permit to change the purpose and place of use of the effluent of the Water Reclamation Facility it will be necessary to accomplish the detailed design of these mitigation measures, monitor their construction, and then monitor the success of the measures for at least 5 years. At this time it is estimated that the cost of obtaining this work through a qualified consultant will be close to $200,000. The existing contract with Fugro West, Inc. was awarded on April 12, 1994 in the amount of $12,090.00 following a formal request for proposals. Addendum No. 1, in the amount of $2,900.00, was approved by the Utilities Director on March 2, 1995 to evaluate additional minimum discharge flows of 1.7 and 3.0 cfs. Addendum No. 2, in the amount of$16,514.00, was approved by City Council on June 13, 1995 to expand the evaluation of impacts on the Tidewater Goby. Addendum 3, in the amount of$4,350, was approved by the CAO on August 24, 1995 to provide hydrologic analysis associated with the impacts to the Tidewater Goby. a_3-/ Council Agenda Report- Water Reuse Project - Biological Resources N[itigation Plan Page 2 FISCAL EMPACT Approval of the recommended action will authorize execution of an $18,903.00 contract addendum with Fugro West, Inc., for mitigation plan services, and approve up to $2,000.00 in contingency funding , if needed, for these services. FUNDS REQUIRED Previous Expenditures Mitigation Plan $18,903.00 Basic Contract 12,090.00 Contingencies 2,000.00 Addendum No. 1 2,900.00 $20,903.00 Addendum No. 2 16,514.00 Addendum No. 3 4,350.00 This Addendum (No. 4) 18.903.00 Revised Contract Total $64,757.00 The Water Reuse Project CIP - Study budget (500-9124-510-551) has a balance of $72,900 to support the recommended action. During the 1995-96 Mid Year review, $75,000 was added to the studies phase including $35,000 that was identified for this additional work to be completed by Fugro in preparation of the mitigation plan. Water Reuse Project Studies Phase Expenditures to date: $35,854.00 to Fugro West Biological Resources Evaluation $44,344.00 to Stetson Engineers Hydrologic Model $ 8.133.22 to Thomas Payne & Associates Instream Flow Study $88,331.22 ALTERNATIVES A contract could be awarded to Fugro West, Inc., for all the remaining work that will be required to complete the project. This includes design, construction monitoring, and monitoring of the success of the mitigation measures. The award of such a contract is estimated to cost $200,000.00. However, the scope would be in very general terms because the specific projects to be designed have not yet be defined. Staff recommends that at this time the contract be awarded as recommended and that additional contracts be awarded for the additional services when the scopes are more clearly defined and the costs can be more closely estimated. Following completion of this phase of work it may be preferable to seek proposals for the remaining work related to design and construction. Staff will evaluate this option and provide an appropriate recommendation to Council upon completion of this phase of work.

Select and Prioritize Mitigation Measures Fugro staff will meet with the City to discuss mitigation objectives and phases of the mitigation plan for the Water Reuse Project. Fugro will develop a mitigation summary table that will indicate the level of priority for implementation and preliminary information on potential constraints and benefits of each measure. Fugro will submit the mitigation summary table to the City for review and comment. All requested revisions will be incorporated prior to the meeting with U.S. Fish and Wildlife Service(USFWS). Fugro will meet with the City and resource agency representatives (e.g., USFWS) to determine/agree on impact assessments for special-status species, primarily tidewater goby. Fugro will review proposed mitigation measures with the City and USFWS to develop and agree on mitigation priorities and preliminary mitigation plan concepts. Based on discussions with USFWS and the City, Fugro will prepare a final mitigation summary table that indicates mitigation implementation priorities. This mitigation summary table will be used as a guide throughout the next project phase, when selecting mitigation measures in coordination with the City, and will be used by the City for the Final EIR. Task I-2. Develop a Preliminary Mitigation Plan Proposal Outline Fugro will prepare and submit to the City and applicable resource agencies a preliminary mitigation plan proposal outline for review and consideration. The preliminary mitigation plan will identify potential mitigation sites of each aspect (e.g., target species) and mitigation targets (i.e., aerial extent, mitigation requirements, etc.). No data on proposed mitigation sites will be gathered during this task. Task I-3. Meet with the City, Resource Agency Staff, and Land Conservancy Fugro will meet with the City, resource agencies, and Land Conservancy to discuss objectives and proposed concepts of the mitigation plan. This task assumes that Fugro (up to three persons) will attend one meeting in San Luis Obispo. uuwtttmmon.t�at-sow�tr ........... May 16, 1996 a 6R0 Project No. 96-61-1651 Task 14. Develop a Final Mitigation Plan Proposal Outline Fugro will finalize the preliminary plan outline after the City and agency review comments are received. The revised outline will be submitted to the City for review and comments will be incorporated into final mitigation plan proposal. Task 1-5. Develop a Final Mitigation and Monitoring Plan After the City has decided on specific mitigation sites and details, Fugro will prepare a final written mitigation plan and submit to the City for approval, with location maps of mitigation sites. The plan will describe in detail what mitigations will be implemented to offset significant impacts to biological resources in San Luis Obispo Creek. The plan will identify specific mitigation measures that avoid, minimize, or compensate for significant impacts to special-status species resulting from implementation of the 1.7 cfs discharge proposal. The plan will identify mitigation measurement criteria that must be attained or maintained for a predetermined number of years. A monitoring program will also be developed to satisfy CEQA mitigation monitoring requirements. The plan will be presented in graphic and report formats and submitted to the City and resource agencies for review. Task 1-6. Meet with Interested Parties Fugro will meet with the City, resource agencies, Land Conservancy, and other interested parties in a workshop format to discuss the objectives and concepts of the mitigation plan and monitoring program.

The following scope of additional services is based on these discussions. Task 4.2 Preparation of Draft Biological Assessment The biological assessment will analyze potential impacts associated with the two reclamation scenarios proposed by the City. Analysis will include a description of the existing conditions regarding general riparian vegetation and wildlife resources and sensitive species habitat and populations, assess potential impacts associated with each scenario, and recommend appropriate mitigation measures as necessary. A specific scope of work for preparation of the Biological Assessment is presented below. Task 4.2.1 Assessment of Existing Resources/Conditions A. Identify sensitive species documented as occurring in or adjacent to San Luis Obispo Creek or species that may occur based on the presence of suitable habitat. Sensitive species will include all Federally or State listed species, including candidate species, and species of local importance. At a minimum, the investi- gated species will include the southwestern pond turtle, red-legged frog, two striped garter snake, tidea,ater goby, Chorro Creek bog thistle, and the San Luis mariposa lily. This assessment of sensitive species occurring in or adjacent to San Luis Obispo Creek will include the following: • Use of RAR.EFINI) to access CDFG's California Natural Diversity Data Base (CNNDB) • Review of the "Biological Resources" section of the DF_IR • Search for and.evaluation of pertinent literature and previous. biological surveys conducted on the resources of San Luis Obispo Creek • Consultation with staff of CDFG, USFWS, SWRCB, and biologists at the California State Polytechnic University (Cal Poly). 93•P4148-90I B.0 -l- —31 �/ March 1994 Giza Project No. 9448.8018 L�� • Review of pertinent Cal Poly senior theses relating to the distribution of various sensitive species along San Luis Obispo Creek. B. Determine habitat preferences of sensitive species documented as occurring in San Luis Obispo Creek. Specific seasonal habitat requirements for these.species %%U be addressed. This task will primarily be accomplished using resources indicated above. C. Determine habitat availability in San Luis Obispo Creek and adjacent areas potentially utilized by these species. Parameters to be included in this habitat assessment are water quality, flow rates, cover, and food availability. Habitat currently available for these species will be determined through: • Contact with resource agency staff and Cal Poly biologists. • Review of current and historic aerial photos. • Review of historic and current streamflow data (Assumed to be available through the hydrologic study). This will require the City to provide average monthly discharge rates to compare the two scenarios. • Limited field surveys (2 days in field). • Review of the information associated with the Instream Flow Study conducted by Thomas R. Payne and Associates (for location of various habitat types within the study area). D. Determine the type and quantity of general riparian habitat along the creek corridor downstream of the discharge point. It is assumed that the habitat mapping from the geographical information system (GIS) will be available free of charge and on a timely basis through the Regional Water Quality Control Board. Contract with RWQCB indicates that it should not be difficult obtaining the needed data. This mapped information will be checked through: • Review of current aerial photos. • Expansion of the field surveys to include spot checks along the creek for ground-truthing of the GIS maps. • Acquisition of coverage data from the Instream Flow Survey conducted by Thomas R. Payne and Associates. SSP<:ef-FO1F.0 -2- �_ d ���— March 1994 Project No. 9948•E078 �E—�� . During the field surveys, characterization of habitat along San Luis Obispo Creek will primarily be restricted to those areas that would most likely support the identified sensitive species. Aerial photos and available literature will be utilized to select specific sites within the study area to collect habitat data. The field surveys will focus primarily on the lagoon located at the mouth of San Luis Obispo Creek, where the tidewater goby has been documented as occurring, and on slower moving reaches of the stream containing pools with substantial cover, which are considered particularly important habitat for the southwestern pond turtle and red- legged frog. The survey will also include a search for bullfrogs since the presence of this species would indicate that red-]egged frog populations may no longer be viable along San Luis Obispo Creek. To further characterize wildlife habitat and augment the fisheries study, a variety of data will be collected at chosen study areas. These data.will include but not be limited to, habitat type, stream depth, streambank slope, substrate type, and type and approximate amount of instream and riparian cover. Data gathered during the field surveys will be incorporated with information compiled from the sources previously discussed and the GIS mapping to produce maps that identify the general locations of potential sensitive species habitat within the study area and illustrate the extent of riparian habitat. Task 4.2.2 Impact Analysis The primary impact associated with water diversion in San Luis Obispo Creek is the ' reduction in surface water, particularly the size and duration of pools. These pools are suitable breeding habitat for the southwestern pond turtle and red-legged frog, and foraging habitat for the two-striped gal–ter snake. These species need near-permanent pools with vegetated mzrgins which may be lost if water is diverted. A. Identify project impacts to sensitive species for each discharge scenario. The impact analysis will compare each project scenario to the existing discharge flow of 5.5 cfs. Predicted habitat conditions associated with implementing each alternative will be determined through review of data produced as part of the expanded. Instream Flow Study being conducted by Thomas R. Payne and Associates and the hydrologic study being conducted by Stetson Engineering. It is assumed that the hydrologic study would include sufficient analysis to determine surface water conditions along the various reaches downstream of the effluent discharge point. B. Evaluate beneficial and/or detrimental impacts to sensitive species associated with each project scenario. Utilizing predicted flow data associated with each project scenario, resulting seasonal changes in habitat quality anticipated at the various study locations will be evaluated based on information obtained during the s:.paras-so�s.c -3- — ice` March 1994 Project No. 9948-8018 rar ccxa;�a literature review and typical habitat values. Predicted habitat conditions associated with each project scenario will be compared to species habitat preferences, critical seasonal flow requirements and improvements and/or reductions in habitat availability will be determined. Direct and indirect impacts to identified sensitive species will be evaluated. Assessment of changes in habitat availability will be quantitativewhere possible. C. Identify probable project impacts to the downstream riparian habitat and anticipated effects on local wildlife populations. Evaluate the cumulative impacts of decreased effluent discharge and agricultural pumpage on the riparian habitat and associated wildlife based on the results of the hydrological analysis. 'Discuss the implications of the project to the potential public trust resources of flora and fauna along San Luis Obispo Creek. Task 4.2.3 1ltitig2tion Nfeasures A. Where negative impacts to sensitive species and/or habitat of these species will likely result, appropriate mitigation measures to reduce impacts to less than significant levels will be developed. Development of mitigation measures will include consultation with staff of DFG and RWQCB, as well as other appropriate resource agencies. B. Methods for implementing specific mitigation measures will be addressed as well as approximate time frames for implementation. Upon completion, 5 Administrative Draft copies of the Biological Assessment will be forwarded to City staff for review. Upon review and incorporation of any staff comments, 15 copies of the Daft Biological Assessment will be forwarded to City staff for circulation to appropriate State agencies for review. Task 4.3 Preparation of Final Biological Assessment Upon review of the Draft Biological Assessment by State agencies, the Fugro project team will review comments received and will prepare written responses as necessary. The proposed budget assumes minimal agency comment, with a maximum of two letters with four comments each. Comments received and corresponding responses, as well as any required revisions, will be incorporated into the assessment. Upon completion, 15 copies of the Final Biological Assessment and one unbound camera ready copy will be forwarded to the City for incorporation-into the DEIR. cru«soy a.c -4- March 1994 Gctn Project No. 9948•8018 ' ="�`• Task 4.4 Response to Comments on the DEIR. The Fugro project team will be available to respond to comments on the Biological Assessment received during the public review period of the DEIR. Upon receipt from the City, written responses to public comment regarding the Biological Assessment will be prepared and forwarded to the District for incorporation into the Final EIR. The proposed budget assumes minimal comment, with a maximum of ten letters with four comments each. Task 4:5 Public Hearings The project manager will attend two public hearings, one during the DEIR public review period and one during the State Water Resources Control Board review period, has been included in this proposal. It is assumed that the State Water Resources Control Board review will b&-conducted in San Luis Obispo; if not, additional travel costs would be charged as a reimbursable expense. Attendance by additional staff or additional hearings would be provided on a time and materials basis. Project team staff will be prepared to make public presentations at each hearing attended; however, we have not made allowances for preparation of graphics other than those utilized in the biological assessment. 01 City's sole option, be extea, for such periods as may be agreed upon L. : City avd the Contractor. y` In the event drat there is insufficient time to grant such extensions prior to the completion date of the contract, the City may, at the time of acceptance of the work, waive liquidated damages which may have accrued for failure to complete on time, due to any of the above, after hearing evidence as to the reasons for such delay, and making a finding as to the causes of same, 21.

This scope of work includes five tasks, with subtasks, that will allow us to conduct supplemental field surveys, more fully assess impacts and expand on the mitigation plan, and coordinate more fully with you and the resource agencies. The scope of work and cost estimate spreadsheet are attached as Exhibits A and B. respectively, for your review. The tidewater goby is now listed as endangered, therefore the U.S. Fish and Wildlife Service (USFWS) must be-consulted if the project will cause a "take" of individuals or destruction of its habitat. Consultation with the USFWS needs to occur through the federal agency having permit authority or providing funding for the project. In this case, the U.S. Environmental Protection Agency (EPA) is responsible for informally consulting with the USFWS because EPA is ultimately funding the WRP. During our meeting on April 17, 1995, it was indicated that you would contact the EPA regarding this project and its potential to adversely affect an endangered species. In regard to Stetson Engineers hydrologic model, we recommend that instead of rerunning the hydrologic model, Fugro will evaluate the model's representative years (wet, average, and dry) to determine if they truly represent the wet, average, or dry years. This is important because we are basing our project alternatives impacts on this model; therefore, we must be confident that the years chosen truly reflect expected stream-flow conditions. If the results of our analysis indicate that other baseline years would more accurately ilhistrate expected conditions, we may need to revisit this issue before proceeding with the impact analysis and mitigation plan. Concurrently, Fugro will conduct a survey for the tidewater goby and assess its potential habitat at the lower end of San Luis Obispo Creek. Fugro will contract with Dr. Ramona Swenson, a I.AVVF%l 9WaS-2300*"0LTPL5W A member of the Fugro group of companies with offices throughout the world City of San Luis ObispoU May 30, 1995(95-61-2300) a noted tidewater goby expert (possessing a Section 10A collecting permit from the USFWS) to lead the sampling and habitat assessment.

The City provided letters from the U.S. Fish and Wildlife Service (USFWS) and Central Coast Salmon Enhancement (CCSE), and a summary of issues addressed in meetings between the City, CCSE, Land Conservancy of San Luis Obispo, and California Department of Fish and Game (CDFG). Of primary concern to the USFWS is the potential occurrence of the federally endangered tidewater goby in San Luis Obispo Creek and the need for an expanded analysis of potential project-related impacts to the species' existing habitat. Other resource groups, including CCSE, Land Conservancy, and CDFG, requested that a detailed mitigation plan be developed that would identify specific areas of San Luis Obispo Creek proposed for enhancement. These resource groups requested additional meetings and site visits with Fugro biologists to discuss appropriate mitigation measures and define methods of implementation. Addressing general. comments submitted by agencies and local resource groups in response to the March 1995 draft biological assessment and finalizing our report are included under our existing scope of work submitted to the City in March 1994. However, responding to previously mentioned specific concerns by agencies and local resource groups requires additional work not included in our original scope of work. The following scope of work provides a description of additional work to be conducted as part of completing the final biological assessment and estimated costs for completing each task identified. Additional meetings and project coordination time have also been outlined within the supplemental scope and cost estimate. SCOPE OF WORK Task 1 -Evaluate Hydrologic Data Existing hydrologic data will be evaluated to determine the degree to which each modeled year is representativd,,of dry, average, or wet rainfall/runoff periods. Rainfall data for each modeled year will be compared to 20-year rainfall period and determination will be made as to the percentage of years each modeled year represents. In addition, as part of this task, uwvu�usnsaooioawrwr May 1995 f o RO Project No. 95-61-2300 significance thresholds, as related to the model output, will be clearly defined for each species targeted in the biological assessment impact analysis. These analyses will be used to support our findings of significance in the biological assessment, which will satisfy CEQA Guidelines requirement. Task 2 - Coordinate Project, Supplemental Work This task consists of the additional time needed to coordinate the project as related to expanding the impact analysis. This task includes time spent coordinating with the City and consulting with agencies and other professionals on tidewater goby related issues. Task 3 - Expand Habitat Assessment and Impact Analysis for Tidewater Goby In order to be responsive to comments from the USFWS, the draft biological assessment will be expanded to provide more detailed information on the tidewater goby in San Luis Obispo Creek. As part of the expanded analysis, the lower creek and lagoon will be surveyed for the tidewater goby, existing habitat will be characterized and the suitability of existing habitat will be determined. Following the field surveys, existing data will be used to determine expected impacts to tidewater goby habitat in the lower creek. We propose that Ms. Ramona OHalloran Swenson, from the Integrative Biology Department of the University of California at Berkeley, conduct the tidewater goby habitat assessment and expanded impact analysis. Ms. Swenson specializes in designing and implementing field surveys specifically for tidewater goby and has expertise in its ecology and reproductive behavior. Ms. Swenson's extensive qualifications are detailed in her resume, which is available upon request. A description of the work and methods we will employ are divided into three subtasks. Subtask 3.1 Coordinate with Resource Agencies As part of the expansion of the tidewater goby habitat assessment and impact analysis, close coordination with representatives of the USFWS will be required. The CDFG also has some regulatory authority over fisheries resources in the creek and have expressed interest in the City's project. Fugro biologists will consult with USFWS and CDFG representatives on pertinent regulatory issues and proposed management measures. Subtask 3.2 Perform Field Surveys To evaluate the status of the tidewater goby in San Luis Obispo Creek and assess existing habitat, a field survey will be.conducted by Ramona Swenson with Gaylene Tupen assisting. Surveying of the creek and lagoon area will be limited to a 2-day period, with 1 day scheduled for the subconsultant for mobilization and travel time. The surveys will focus on determining the 0a�� , AJMT - 2 - � May 1995 ORO Project No. 95-61-2300 m presence and locations of gobies in the stream, and characterization of existing aquatic habitat. The lagoon located downstream of Marre Dam will be seined, as part of sampling for the tidewater goby. Other species of fish collected in the lagoon will be cataloged. A determination will be made as to whether other species of fish collected likely co-occur with the tidewater goby. The primary focus of the 2-day survey of the lagoon and lower creek area will be on habitat assessment. Features to be considered will include stream and lagoon morphology, salinity concentration, substrate, water velocity, depth, and vegetation types. Subtask 3.3 Conduct Impact Analysis Based on information collected during the 2-day field survey, existing data from the Hydrologic Study, and on Ms. Swenson's extensive experience, expected impacts to existing tidewater goby habitat resulting from project implementation will be determined. Any beneficial effects of the project on tidewater goby habitat will also be identified: With the exception of information collected during the 2-day field survey, no new data will be provided for the assessment of impacts. Quantification of impacts to tidewater goby habitat will be limited due to the absence of hydrologic data from the See Canyon Confluence downstream to the mouth of the creek. If impacts to tidewater goby habitat are determined to occur as a result of project implementation, wherever possible, measures to reduce impacts to less-than-significant levels will be recommended. Task 4-Prepare Expanded Mitigation Plan As requested by representatives of CCSE, CDFG, and the Land Conservancy, the mitigation plan of the biological assessment will be expanded to include additional information on proposed mitigation site locations on San Luis Obispo Creek and detailed methods of implementation. Representatives from these organizations have various recommendations for mitigating for identified impacts to aquatic resources. This task will involve meeting with representatives from these groups in the field, developing an expanded mitigation plan that includes their recommendations (if appropriate), as well as additional mitigation measures. The following describes methods for implementing each subtask. Subtask 4.1 Meetings and Site Visits With CCSE, CDFG, and Land Conservancy A maximum of 2 days will be scheduled for meeting with representatives from CCSE, CDFG, and Land Conservancy to discuss various mitigation options. A minimum of 1 day will be spent with representatives from CCSE, CDFG, and Land Conservancy, surveying portions of San Luis Obispo Creek targeted for project-related mitigation. Visited areas will include stream reaches identified by resource groups as preferred locations for focusing revegetation efforts. �rnvA,wsysnoo�xNwr GRD May 1995 c �a Project No. 95-61-2300 Subtask 4.2 Expand Mitigation Plan in Report Using information obtained during site visits and meetings with CCSE, CDFG, and Land Conservancy, the mitigation plan section within the biological assessment will be expanded to focus on specific areas identified for revegetation, provide more detailed methods for implementing mitigation measures, and contingency plans. General locations of revegetation/enhancement sites along San Luis Obispo Creek, as related to the project, will be mapped. The mitigation plan section will not include plans and drawings suitable for construction bidding but will provide detailed conceptual drawings and descriptions of the mitigation measures. Task 5-Attend Additional Meetings With City This task includes previous and future meetings occurring with City stag. (One out-of- scope meeting between Fugro and City staff occurred on April 17, 1995, to discuss comments submitted by resource groups and the agencies and to identify additional work to be conducted. This meeting is included in this scope of work.) As part of this task, Fugro expects that two additional meetings will occur between Fugro and City staff, following completion of all field surveys and prior to submittal of the final biological assessment. COST ESTIMATE Our estimated cost to complete the proposed supplemental scope of work is $16,514. The costs for responding to general agency comments, finalizing the biological assessment and attending public hearings is already covered under our existing March 1994 Scope of Work and contract (Project No. 94-48-8018). An illustration of cost per task for the supplemental work is provided in Exhibit B; however, Fugro retains the right to allocate funds between tasks as needed to complete the project. � „ - 4 - • �6RD a m Tn N ° U'r H O H H H H - p u F H � r � coi e r c m m r ooa �p O ••� U F H H H H N H N H H ee - y � - u � � s a Q a m n o E o a Tn H C 'pp t m N N to C _ ,M.� N yq Q C H oo V fV H 1+�1 L -•� U y K H H K H H Vi H O Lo O H G R w � m - O c y H a H H O O Cn u m v h e m n e r ,_, u H a m .0..

Pierce Water Projects Manager i City of San Luis Obispo 955 Morro Street San Luis Obispo, California 93401 Dear Dave, This letter addresses the estimated cost and time frame for completing the work we outlined in your fax, dated October 3, 1994, and discussed in our conference call on October 5, 1994. 1. Revise Scenarios A and B per new WRF discharge schedule This work will require relatively minor revision to the data files for each of the three years simulated and each scenario. Once the model is run, fairly extensive review, error checking and data extraction will be necessary. The diversions that are not taken by the model in these Scenarios will be different for this run than in earlier versions. The output must be checked manually against the input data and the report tables must be revised. 2. Scenario D - Natural loss of the creek This scenario will require fairly extensive revision of two input files for each year simulated. Again most of the effort is in error checking, extracting the stream flow, drawdown and budget data and tabulating and writing up the results. The method for presenting these losses require additional effort since it is not a direct model output. 3. Scenario E - Change surface diversions to pumping as_necessary to maximize use of natural flow This scenario will require extensive revision of pumping and stream flow data files for each year. The mix of diversion and pumping will be optimized for each year and possibly each W A T E R R E S O U R C E E N G I N E E R S F.KA i7- A /I_ !3- STETSON ENGINEERS INC. month on a trial and error basis. Up to 14 new well sites will be selected and figures and tables will.be adjusted or added accordingly in order to summarize results. A uniform reduction of pumping and diversion may be necessary during the dry year and possibly during the normal year. The final simulations for this Scenario will reflect any such reductions. 4. Scenario F - Change surface diversions to pumping as necessary to maximize use of natural flow with the addition of a minimum of oneds WRF discharge per the new schedule ti This scenario will require relatively minor revision to the data files for each year with the usual effort to extract the data, create the necessary tables and figures and report on the . findings. The timing and configuration of pumping and diversion will be the same as that developed in the latter scenario. The cost to complete the above work is shown on the attached table. It includes analysis and reporting, release of preliminary data to FUGRO prior to completion of the final report, release of review copies of the draft final report for City and FUGRO review, and minor revision.of the report after receipt of City and FUGRO comments. Work has begun and we anticipate that preliminary results of all scenarios available by October 24. Preliminary data will by regular mail as it is completed. A one week delay in final analysis and report preparation will occur in late October due to previously scheduled field work. The draft final report will completed by November 7. Thank you for this opportunity continue our work with the ground-water model for the City of San Luis Obispo. Sincerely, �V� Peter M. Pyle 2 1640 Cost Esth for Addtional Work 1.

As you are aware, this area of San Luis Obispo Creek is habitat to the federally endangered Tidewater Goby. Project-related impacts to the Tidewater Giby is a critical issue to the Water Reuse Project- To date no data on surface water flows have been gathered or analyzed on the creek downstream of Highway 101. Stetson Engineers' hydrology model stops at Highway lol; therefore, determining the wetted area and avaliable aquatic habitat in the vicinity of Mane Dam can not be determined reliably without additional data from the target area. The following tasks must be accomplished to provide stage and velocity versus channel flow relationships for different release scenarios on San Luis Obispo Creek at Marre Dam. Fugro proposes to develop this information along four survey transects, two between Marre Dam and Highway 101 and two between Marre Dam and the lower area of Tidewater Goby habitat, as defined by Ramona Swenson. Channel elevation and morphology data (e.g., width, depth, flow rate, substrate) will be gathered at each transect. Fugro will use a Marsh- McBurney or equivalent type flow meter to determine current flow volume and velocity in the lower reach of the creek. These data will be used, in conjunction with Stetson's hydrologic analysis, to calibrate the channel roughness to the known flow and stage measured in the field. Fugro will then develop the stage and channel velocities versus flow relationships for a range of flows using the Mannings Equation for uniform flow in open channels, and plot curves of stage versus discharge and channel velocities versus discharge. These data and analyses will be used to determine changes in the creek's wetted area and available aquatic habitat under each project alternative and how changes in flow may adversely or beneficially affect wetland, riparian, and aquatic habitats that are used by special- status species. The special:status species likely to be affected by the Water Reuse Project include Tidewater Goby, Southwestern Pond Turtle, and Southern Steelhead Trout.
