The property is currently designated as a Contributing List Resource and is located with the Downtown Historic District. Previous Council or Advisory Body Action On April 26, 2021 the Cultural Heritage Committee considered this request and found that the property meets eligibility criteria for historical listing to a degree that qualifies it for designation as a Master List Resource and recommended that the City Council designate the property as such in the City’s Inventory of Historic Resources. Site and Setting The property is on the south side of Dana Street, about 400 feet west of Nipomo Street, within a smaller residential section of the Downtown Historic District that includes a spectrum of settlement from the mid-19th century to the 1920s. The applicant has provided an evaluation of the property and its eligibility for historic listing prepared by Betsey Bertrando of Bertrando & Bertrando Associates (Attachment B). Page 15 of 422 Item 6c The dwelling that is the subject of this evaluation was originally constructed in the late 19th Century, from about 1887, on property across Dana Street (at 550), and moved to the subject site in 1914.1 The property (531 Dana) appears as a “Contributing Property” on the listing of historic properties adopted by the City Council in 1988 (by Resolution No. 6424). Building Architecture As described in the applicant’s Historic Resource Evaluation, the dwelling reflects Victorian vernacular architecture,2 sheathed in shiplap siding, with several distinctive elements: Unusual mix of roof lines, including flat front and gable with two-patterned shingle Square bays on front façade, with ins-set columns at corners and continuous sill Recessed porch with flat sawn balusters, wood railing, and saw cut border of circles above The City’s Historic Context Statement describes the growing prevalence of wood fra me construction in the City’s late 19th-Century Residential Development, noting representative forms and styles of the era that include cottages and Folk Victorian. The specific architectural and historical characteristics of the building are more fully discussed in the Historic Resource Evaluation submitted with this application, and summarized in the Evaluation section of this report, below. John Wesley Barneberg and Grace Barneberg The applicant’s Historic Resource Evaluation also provides biographical details about John Wesley Barneberg and his daughter Grace, who are most closely associated with the property. John Wesley Barneberg, born in Iowa, had been farming in Arroyo Grande and relocated to Dana Street after marrying Sarah Elizabeth Anderson in 1873. As more fully described in the Historic Resource Evaluation, he was active in the community, running a foundry and machine shop and a hardware store, serving as City Tax Collector, and involved in many civic committees, later becoming president of two local banks, and having some success in exploration and development of oil resources in the region. 1 See description of building history, from page 17 of the Bertrando Historic Resource Evaluation (Attachment B) 2 Bertrando, Historic Resource Evaluation (Attachment B), from pg. 23. Figure 1: 531 Dana (1995 View) Page 16 of 422 Item 6c His daughter Grace lived much of her life in the house, up until the time of her death. She taught high school, having been educated at Stanford and Berkeley, was one of the founders of the Monday Club, and was active in several local organizations and boards. She also helped her parents raise her brother’s two children, Helen Maxine and Jack Barneberg, grandchildren of Charles William Dana, who, in turn, was the son of William Goodwin Dana. Further detail, including discussion of the intertwined relationship between the Dana and Barneberg families, is provided from page 11 of the applicant’s Historic Resource Evaluation (Attachment B). Evaluation of Eligibility To be eligible for listing as an historic or cultural resource, the resource must exhibit a high level of historic integrity, be at least 50 years old, and meet one or more of the eligibility criteria described in § 14.01.070 of the Historic Preservation Ordinance (see Attachment C). As provided in § 14.01.050 of the Ordinance, the most unique and important resources and properties in terms of age, architectural or historical significance, rarity, or association with important persons or events in the City’s past may be designated as “Master List Resources.” 1. Architectural Criteria As described in the applicant’s Historic Resource Evaluation, the dwelling exhibits many characteristic features of Victorian vernacular examples form the late 19th Century, in a manner that expresses interesting details with notable attractiveness, consistent with listing criteria for “Style” and for “Design”: The 1880s architectural style of the Dana/Barneberg House used an abundance of elements that were popular with the prominent citizens of San Luis Obispo at that time. Using elements found on Queen Anne cottages such as the squared bay, panels under the windows, and shingle work under the gables, it also represents a composite of borrowed elements. The saw cut balustrades and scroll sawn border under a narrow front facing gable behind a shed roof belie other aspects of design. […] (pg. 26) 2. Historic Criteria The Historic Resource Evaluation provides a summary (pp. 26 & 27) of the local activities in which John Wesley Barneberg and his daughter Grace were engaged, illuminating their contributions to the local community, and notes the association of the Barnebergs with the Dana family, to demonstrate the association of this property with the lives of persons important to local history, as described by listing criteria for “History – Person.” Page 17 of 422 Item 6c 3. Integrity To demonstrate satisfaction of listing criteria for “Integrity,” the Historic Resource Evaluation notes the retention of the original design, footprint, and character- defining elements of the home intact in moving to its current site from its original site across Dana Street, the lack of significant alteration of the building, and its sensitive restoration in 2006, overseen by Darryl Joseph “Joe” Shauerman, a local glazer and craftsman (pp. 20-21, pg. 28). Overall, the house retains more than enough of its character to communicate its significance as an innovative, abstracted example of Minimal Traditional architecture with some extraordinary interior features. (pg. 24). Conclusion The information in the Historic Resource Evaluation prepared for this application, documenting the architectural character and integrity of the house, and describing the people associated with the property, provides a basis for the Council to find that the dwelling satisfies Architectural Criteria for Style and Design (§§ 14.01.070 (A) (1) & (2)), Historic Criteria for “History-Person” (§14.01.070 (B) (2)), and Criteria for Integrity (§§ 14.01.070 (C) (1) & (2)), to a degree that qualifies the property for designation as a Master List Historic Resource. Policy Context The recommended action on this item is supported by historical preservation policies set out in § 3.0 of the Conservation and Open Space Element of the City’s General Plan, and with procedures and standards for listing of historic resources set out in the City’ s Historic Preservation Ordinance §§ 14.01.060 & 14.01.070. Public Engagement Public notice of this hearing has been provided to owners and occupants of property near the subject site, and published in a widely circulated local newspaper, and hearing agendas for this meeting have been posted at City Hall, consistent with adopted notification procedures. Public notice was also previously provided for the Cultural Heritage Committee meeting of April 26, 2021. ENVIRONMENTAL REVIEW This project is categorically exempt from the provisions of the California Environmental Quality Act (CEQA). Inclusion of the subject properties on the City’s Inventory of Historic Resources does not have the potential for causing a significant effect on the environment, and so is covered by the general rule described in § 15061 (b) (3) of the CEQA Guidelines.

Decline to designate the property as a Master List Resource in the Inventory of Historic Resources. This decision would be based on finding that the Property is not considered to be sufficiently unique or important, or found to satisfy Evaluation Criteria for listing to a degree warranting such designation. The Property would remain in the Inventory as a Contributing List Resource. 2. Continue consideration of the request for additional information or discussion.

Agenda of: 6/15/2021 Placement: Consent Estimated Time: N/A FROM: Greg Hermann, Deputy City Manager Prepared By: Lee Johnson, Economic Development Manager SUBJECT: DOWNTOWN SLO AGREEMENT 2021-23 RECOMMENDATION Authorize the City Manager to negotiate and approve the two-year agreement with Downtown SLO and other agreements as needed to execute the Downtown related initiatives in the 2021-23 financial plan. DISCUSSION The City’s Economic Development Program is responsible for implementing the policies laid out in the City’s Economic Development Strategic Plan (EDSP) as well as the initiatives outlined in the City’s Economic Recovery, Resiliency and Fiscal Sustainability Major City Goal. The recovery and vitality of the City’s downtown is a critical piece of the City’s short- and long-term economic health. Background The agreement with Downtown SLO (Attachment A) is the foundation of the City’s cooperation to ensure the success of the downtown. Downtown SLO’s mission is to foster an economically vibrant downtown by providing promotional activities to benefit downtown businesses including but not limited to Farmers’ Market, Concerts in the Plaza, and seasonal holiday events. The Downtown SLO also manages the Clean and Safe Ambassador Program which provides litter and graffiti removal, sidewalk and gutter sweeping, and cleaning services beyond the baseline services provided by the City. Downtown SLO also provides an educational series on a wide range of topics for business owners, managers, and employees. This agreement also includes several new initiatives including, the “Light up Downtown” holiday program, leading a vacancy task force , and supporting the “Dining in the Plaza” initiative. In addition to the City collected revenue through the Downtown Business Improvement District assessments, which is passed directly to Downtown SLO, the City is also planning to allocate up to $150,000 ($100,000 in direct funding and up to $50,000 in matching funds) per year in additional funding for the “Light up Downtown” holiday program and up to $65,000 in funding for the Clean and Safe Program per year. Page 73 of 422 Item 6d This report requests authorization for the City Manager to negotiate the final funding and scope of work based on the adoption of the financial plan and current status of the State’s reopening plans. Previous Council Action On June 18, 2019, the Council approved the last two-year agreement with Downtown SLO. Policy Context The recommendation for renewing agreements for the years 2019-21 are supported by the City’s EDSP and the adoption of the 2021-23 Major City Goal of Economic Recovery, Resiliency and Fiscal Sustainability. Public Engagement Through forums and surveys, community members expressed a desire for the downtown to remain a focus as part of the 2021-23 Major City Goals. CONCURRENCE The proposed agreement for Downtown SLO has the concurrence of the Administration, Police, Parks and Recreation, Public Works and Utilities departments. ENVIRONMENTAL REVIEW The California Environmental Quality Act does not apply to the recommended action in this report, because the action does not constitute a “Project” under CEQA Guidelines Sec. 15378. FISCAL IMPACT Budgeted: Yes Budget Year: 2021-22,2022-23 Funding Identified: Yes Page 74 of 422 Item 6d Fiscal Analysis: Funding Sources Total Budget Available Current Funding Request Remaining Balance Annual Ongoing Cost General Fund $430,000 $430,000 $0 $215,000 Other (Special Fee District): $505,000* $505,000 NA Total $935,000 $430,000 $505,000 $215,000 *The budget for the downtown assessment is $245,000 for 2021-22 and $260,000 for 2022-23. This position is not part of this contract but is shown for reference. ALTERNATIVES The City Council may choose to not authorize the City Manager to negotiate and approve the two-year agreement and other related agreements. This is not recommended as Downtown Vitality is a key component of the Major City Goal of Economic Recovery, Resiliency and Fiscal Sustainability. The City Council may choose to approve partial funding for the agreement. This is not recommended as the proposed agreements are cost effective tools in advancing the City’s economic development initiatives. ATTACHMENTS A – Downtown SLO Agreement 2021-23 Page 75 of 422 Page 76 of 422 1 AGREEMENT THIS ECONOMIC DEVELOPMENT AGREEMENT is made and entered into in the City of San Luis Obispo on _____________________________, by and between the DOWNTOWN SLO, a 501(c)(6) non-profit corporation organized under the laws of the State of California, with a place of business at 1135 Chorro Street, San Luis Obispo, California 93401 ("DSLO"), and the CITY OF SAN LUIS OBISPO, a municipal corporation and charter city ("City"). W I T N E S S E T H: WHEREAS, on October 6, 1975, the City Council adopted, and subsequently amended on various occasions, Ordinance 649 (1975 Series) (collectively, "the Ordinance") creating the Downtown Parking and Business Improvement Area (“BIA”) in the downtown area of San Luis Obispo, and levying the authorized assessment on all businesses within that area; and WHEREAS, the City and DSLO have benefited from a close working relationship for the benefit of business and tourism in the downtown area of San Luis Obispo since the inception of the Downtown Parking and Business Improvement Area in 1975 and desire to continue their relationship for the betterment of tourism and business; and WHEREAS, DSLO is uniquely qualified to provide the promotional activities services contemplated under this contract due to its intimate knowledge of downtown, unique connection to businesses in the downtown, and its long experience producing and providing promotional services for the benefit of DSLO members; and WHEREAS, DSLO has historically added substantial value to the events produced under contract with the City by utilizing the financial resources of its membership and dedication of its staff that in total far exceed the BIA assessment revenues; and WHEREAS, DSLO brings experienced and competent management of the subcontractors that it hires for the contracted events; and WHEREAS, both parties acknowledge that the Thursday Night Farmers’ Market, Concerts in the Plaza, and Holiday Activities are unique events that activate the downtown city streets and public areas and draw visitors; and WHEREAS, having determined that promotional activities to benefit business and tourism activities in the downtown area of San Luis Obispo are an appropriate use of BIA assessment proceeds since such activities are expected to maintain and increase revenues derived by the City from the downtown area and to preserve and enhance the unique character of the downtown for the special benefit of downtown area businesses, and further, having determined that DSLO is able to conduct such promotional activities, the City Council desires to contract with DSLO to conduct promotional activities in the downtown area of San Luis Obispo using BIA assessment proceeds; and Page 77 of 422 2 WHEREAS, the City is authorized to enter into a contract to provide services to the members of the BIA and to administer the assessment collected for that purpose; DSLO, a 501(c)(6) organization, wishes to enter into this contract with the City to provide agreed upon services to the BIA members. NOW THEREFORE, in consideration of their mutual promises, obligations, and covenants hereinafter contained, the parties hereto agree as follows: 1. Scope of Services. DSLO will conduct promotional activities to benefit business, cultural, and tourism activities in the downtown area of the City, more specifically set forth in this Agreement as the Scope of Services, attached hereto as Exhibit A and incorporated as if fully set forth herein, as limited by State law and the Ordinance, and subject to any modifications approved in writing by the City Manager. During the term of the contract, the Scope of Services, Exhibit A may be amended by mutual consent of the parties. The City Manager is hereby authorized to approve periodic amendments to Exhibit A without further consent by Council to the extent that any such amendments do not result in the elimination of required Special Events, as set forth in Exhibit A. 2. Financial Reporting. DSLO will prepare and file with City, consistent with City policy, quarterly financial reports within 60 days after the end of the quarter showing qualifying expenditures made by DSLO and shall, upon request by City, produce supporting invoices, receipts, vouchers and statements showing how the BIA revenues have been expended consistent with this Agreement. Such financial reports shall include a line-item schedule that matches expenditures with specific, budgeted amounts and activities. The reports will be filed with the City Finance Director consistent with the City’s financial reporting policies and practices, and as reasonably requested by the Finance Director. In addition to interim quarterly reports, DSLO shall contract with an independent certified public accountant to prepare an annual compilation of DSLO’s financial operations related to qualifying revenues and expenses. Said compilation shall be completed every year, at the end of the contract period and shall show the purposes to which the BIA funds were applied by providing the name and date of the event and the allocation of BIA funds relative to the costs of the event. The compilation shall be conducted in accordance with accounting standards generally accepted in the United States. The objective of a compilation is to assist management in presenting financial information in the form of financial statements without undertaking to obtain or provide any assurance that there are no material modifications that should be made to the financial statements. DSLO’s fiscal year shall be July 1 to June 30; and the compilation shall be completed and submitted to the City’s Finance Director within 180 days of the fiscal year end. The City reserves the right to request an audit of DSLO financial statements and DSLO agrees to comply with such a request, in intervals no more often than every four years nor less often than every six years. Page 78 of 422 3 3. Quarterly Activity Reports.

Page 93 of 422 Page 94 of 422 Item 6e Department: Fire Cost Center: 8503 For Agenda of: 6/15/2021 Placement: Consent Estimated Time: N/A FROM: Keith Aggson, Fire Chief Prepared By: Rodger Maggio, Fire Marshal Chief Building Official SUBJECT: AUTHORIZATION TO CONTINUE THE COLLECTION OF MULTI- DWELLING PROPERTY FIRE AND LIFE SAFETY INSPECTION FEES RECOMMENDATION Adopt a Resolution entitled, “A Resolution of the City Council of the City of San Luis Obispo, California, authorizing the San Luis Obispo County Auditor to collect fees for 2021-22 Fire and Life Safety Inspections of Multi-Dwelling Properties containing three or more dwelling units on the Secured Property Tax Roll pursuant to California Government Section 54988, Et Seq.” DISCUSSION Background In May 2005, the City Council approved a cost recovery program for State-mandated fire and life safety inspections for multi-dwelling properties with three or more units. In June 2017, the Council approved a change on how fees for apartment buildings, hotels/motels, and sorority/fraternity inspections are calculated. This change is reflected in Exhibit A to the Resolution (Attachment A). The result was an increase from approximately $194,000 per year in gross revenue to approximately $260,000 at the time of change in the fee schedule. Since the adoption of the new fee schedule, revenue under this program has increased to $325,000 for fiscal year 2021-22 due to the increase in the number of units for each category and the annual CPI adjustment to the fee. Staff is not recommending any further changes in the current fees for 2021-22, however, the County requires an annual resolution adopted by the Council authorizing the continued collection of those fees on the property tax roll. Staff is recommending that the fee collection continue to be done through the secured property tax role in 2021-22 and is requesting that Council adopt the required resolution to authorize that collection. Policy Context California Health & Safety Code Section 13146. 2(b) authorizes cities to charge property owners in recovering the reasonable costs of providing these annual inspections. As part of this program, on June 7, 2005, the Council adopted Ordinance No. 1472 authorizing the collection of annual fees for these inspections through the secured County property Page 95 of 422 Item 6e tax roll as the most cost-efficient method for fee collection (City Municipal Code Section 3.50.01(c)). Public Engagement This item is on the agenda for the June 15, 2021 City Council meeting and will follow all required postings and notifications. The public will have the opportunity to provide comment on this item at or before the meeting. ENVIRONMENTAL REVIEW The California Environmental Quality Act does not apply to the recommended action in this report, because the action does not constitute a “Project” under CEQA Guidelines Sec. 15378. FISCAL IMPACT Budgeted: Yes Budget Year: 2021-22 Funding Identified: N/A The Finance Department will work with the County of San Luis Obispo to place the fees on the annual tax rolls. Fiscal Analysis: Funding Sources Total Budget Available Current Funding Request Remaining Balance Annual Ongoing Cost General Fund N/A N/A N/A N/A State Federal Fees Other: Total N/A N/A N/A N/A In fiscal year 2020-21, the City is scheduled to collect roughly $325,000 in multi-dwelling property fire and life safety inspection fees. As of May 10, 2021 the City had collected $287,015 with the remaining amount expected to be posted in the near future as the deadline to pay property taxes was April 10, 2021 and tax payments are now delinquent. Projected revenue for fiscal year 2021-22 is expected to increase due to the increased number of multi-dwelling properties within the City. Page 96 of 422 Item 6e ALTERNATIVES Do not adopt the Resolution and go to a less cost-effective billing system by the Finance Department. This is not recommended as it would be counter to fiscal sustainability while the City continues to navigate the fiscal impacts of COVID-19 health restrictions.

Page 102 of 422 Item 6f Department: Parks and Recreation Cost Center: 7008 For Agenda of: 6/15/2021 Placement: Consent Estimated Time: N/A FROM: Greg Avakian, Parks & Recreation Director Prepared By: Dave Setterlund, Recreation Supervisor SUBJECT: ACCEPTANCE OF JACK HOUSE ART RESTORATION DONATION RECOMMENDATION Authorize the Mayor to execute a donation agreement with the Jack House Family Trust, accepting a donation valued at $7,450 for its payment for contract Art Restoration and Installation work at the Historic Jack House. DISCUSSION Background The Jack House and Gardens, a community gem, is in the heart of downtown San Luis Obispo at 536 Marsh Street and was deeded to the City in 1975. The Jack House Committee (JHC) was established in 1975 as a condition of the grant deed of the former Jack Family residence to the City. The JHC is comprised of a seven-member committee that serves to assist the City Council and Parks and Recreation Department in the administration and restoration of the historic Jack Residence. The JHC makes recommendations for general rules and regulations that allow for the greatest possible public use and enjoyment of the house and grounds, while protecting and preserving the history and integrity of this historical and recreational facility. In deeding this facility to the City, the Jack Family descendants articulated their desires to keep, preserve, and use the property and the residence in a manner which maintained, enhanced, and celebrated its place in the historical development of the City of San Luis Obispo. The grant deed (Attachment B) specifies that the residence shall be maintained in its original character, a Victorian vintage residence. General maintenance and any restoration improvements are to be in keeping with the age and period when the original residence was constructed. For the past 46 years, the residence and public gardens have been home to a variety of tours, special events, and weddings. During non-pandemic times, this historic location is visited and enjoyed by thousands of community members annually. Page 103 of 422 Item 6f Need for Art Restoration Recently, City staff was approached by the Jack House Committee with the proposition of an art restoration project within the interior of the historic residence. The current works of art (Attachment C – Works of Art) are aging and some are in poor condition. Further deterioration of the artwork could result in permanent damage if not addressed in the immediate future. Proposed Donation The Jack House Committee, in collaboration with the Jack Family Trust executor, and Parks and Recreation Department staff, have worked to identify a local Conservator, Patina Conservation Studios, who could provide the necessary paper conservation and archival materials work. The estimated cost of Patina Conservation Studios’ conservation and archival materials restoration work is approximately $7450. The Jack Family Trust proposes to donate funds for the installation and restoration of the identified works of art at the City of San Luis Obispo Historic Jack House. In communication with the Jack House Committee, staff has drafted and included a proposed donation agreement to memorialize the terms of this donation (Attachment A). Previous Council or Advisory Body Action At the May 12, 2021 Jack House Committee meeting, the board recommended council approve the execution of in-kind donation, not to exceed $7500. (Attachment E – Draft Minutes). Policy Context Parks and Recreation and Public Works Department staff have reviewed the proposed art restoration donation for consistency with the City’s approved donation policy (Attachment D – Donation Policy). Per the City’s Donation Policy, all donations exceeding $5000 in value must be accepted through a written agreement and approved by City Council. The proposed donation is consistent with the grant deed restrictions and the Parks and Recreation Department goals and objectives and will enhance the historical experience of San Luis Obispo residents and visitors. The proposed donation is valued at over $5000 in materials and donated labor. Staff notes that per the City’s Financial Management Manual, the bidding process is not required for either the paper conservation or archival materials restoration work as the value of those contracts are not to exceed $7,500. Public Engagement At the May 12, 2021 Jack House Committee discussed the donation and provided an opportunity for public comment. Page 104 of 422 Item 6f CONCURRENCE The Public Works Department concurs with this recommendation. ENVIRONMENTAL REVIEW The California Environmental Quality Act does not apply to the recommended action in this report, because the action does not constitute a “Project” under CEQA Guidelines Sec. 15378. FISCAL IMPACT The donation is valued at $7450. All project expenditures will be supported by private funds raised by the Jack Family Trust. There is no General Fund fiscal impact associated with Council’s acceptance of this Art Restoration donation. Budgeted: No Budget Year: 2020-21 Funding Identified: Yes Fiscal Analysis: Funding Sources Total Budget Available Current Funding Request Remaining Balance Annual Ongoing Cost General Fund $0 $0 $0 $0 State $0 $0 $0 $0 Federal $0 $0 $0 $0 Fees $0 $0 $0 $0 Other: $0 $0 $0 $0 Total $0 $0 $0 $0 ALTERNATIVES Decline the donation. Declining the Jack House Committee art restoration donation is not recommended as the art restoration and installation donation is consistent with the Jack House grant deed for restoration improvements and are in keeping with the age and period of the original residence. And finally, declining this donation is not recommended as there is no General Fund impact associated with this acceptance.

Authorize the advertisement of Requests for Proposals (RFP) for on-call tree maintenance; and 2. Authorize the City Manager to award the tree maintenance contract to the selected company. DISCUSSION Background The City of San Luis Obispo has a longstanding history of contracting out tree pruning services to maintain the City’s urban forest. The City’s on-call pruning contractor is selected through the Request for Proposal process, through which City Staff selects the most qualified contractor based on company history, ability to perform work, and value to the City. In 2016, the City of San Luis Obispo issued a formal Request for Proposal (RFP) for tree maintenance services to assist the Urban Forest and Natural Resources Programs with tree maintenance tasks in the City’s Parks, Public Right-of-Way, and Open Space. This process resulted in the City obtaining the lowest cost services provided by contractors capable of completing these services in compliance with the City’s Purchasing Policy. This contract term was for four (4) years with an optional two-year extension and was set to expire in August 2022. Due to rising overhead cost, the City’s Tree Maintenance Contractor, Bunyon Bros. recently informed the City they can no longer perform work at the contracted rate. Due to this recent development, the City must advertise a new RFP for tree maintenance services. Page 137 of 422 Item 6g This RFP is for on-call tree maintenance services, which are primarily used by Public Works and Natural Resources. Although not regularly used by other departments, this contract will provide contracted rates to other departments should an unforeseen need arise. The main scope of this contract is for on-call services to assist the City with emergency tree work, minor pruning request, tree removals, stump grinding, and tree plantings. Policy Context The City’s purchasing policy designates maintenance services as a General Services Purchase and requires issuance of a formal RFP document approved by the City Council for services with a cost greater than $150,000. Because trees are dynamic and are impacted by meteorological conditions, there will be years the City’s cumulative contract amount exceeds $150,000. Public Engagement No public engagement is necessary as this is considered to be an administrative item. CONCURRENCE The Office of Sustainability, Parks and Recreation, and Community Development departments concur with these recommendations. ENVIRONMENTAL REVIEW The California Environmental Quality Act does not apply to the recommended action in this report, because the action does not constitute a “Project” under CEQA Guidelines Sec. 15378. FISCAL IMPACT Budgeted: Yes Budget Year: 2020-21 Funding Identified: Yes Fiscal Analysis: Funding Sources Total Budget Available Current Funding Request Remaining Balance Annual Ongoing Cost General Fund PW & Natural Resources $315,000 $150,000 $165,000 $150,000 State Federal Fees Other: Total $315,000 $150,000 $165,000 $150,000 Page 138 of 422 Item 6g Public Works funding for tree pruning services is found in the 2020-21 Urban Forest budgets. The funding level within Urban Forest is expected to remain consistent during the next Financial Plan. The remaining Urban Forest contract funding will be used in a separate forthcoming RFP for large-scale area pruning. Natural Resources funding is used for tree pruning and fuel reduction projects. The program anticipates an increase of $20,000 during the 2021-23 Financial Plan to address hazardous tree removals in creeks and open spaces; however, this amount was not included in the fiscal impacts because the next financial plan has not been approved by the City Council. The remaining Natural Resources contract funding will be used for fuel reduction projects. ALTERNATIVES Deny, or reduce work scope. The Council may choose to deny authorization for the Request for Proposal. Staff does not recommend this alternative as this would reduce the City’s ability to respond to trees related and the frequency of maintenance, which increases the City’s risk of liability.

DISCUSSION Background As enterprise funds, the Water and Sewer Funds finance the City’s water and sewer operations almost entirely through rates charged for service. W ater and sewer rates must be sufficient to cover operations, capital asset maintenance and improvements, debt obligations, and appropriate reserve levels to keep the Water and Sewer Funds healthy and prepared for unforeseen funding needs. Recommended water and sewer rate increases for 2021-22 and 2022-23 are lower than originally projected. The Water Fund is requesting a rate increase of 3.5% effective July 1, 2021 and 3.5% effective July 1, 2022. The most recent rate study, conducted in 2018, projected the water rate increase would need to be 5.5% in 2021 and 5.5% in 2022. The Sewer Fund is requesting a rate increase of 3.5% effective July 1, 2021 and 3.5% effective July 1, 2022. The most recent rate study, conducted in 2018, projected the sewer rate increase would need to be 6.5% effective July 1, 2021 and 6.5% effective July 1, 2022. The City’s rate consultant recently completed a rate confirmation study to confirm or modify the originally forecasted rate increase estimates. As a result of additional revenue from Cal Poly and refined investment and impact fee revenue projections, the rate consultant has now recommended lower than previously projected rate increases. Page 169 of 422 Item 7a Table 1: 2021-23 Proposed Rate Increases July 1, 2021 July 1, 2022 Water 3.5% 3.5% Sewer 3.5% 3.5 % Proposed Water Rate Increase The water rate increase is driven primarily by the need to maintain consistent and reliable water treatment and delivery service, a high credit rating, and to maintain an adequate working capital balance to cover unanticipated expenses associated with aging infrastructure. Long Term Fiscal Health and Infrastructure Maintenance Both the City’s source water and treated drinking water infrastructure are aging and need to be continually maintained. The amount of work needed to ensure continued service is high with source water supplied to the City from reservoirs as far as 50 miles away and with over 190 miles of publicly owned drinking water pipelines inside the community, the majority of which have not been replaced since their original construction. The Water Fund has a bond issuance that requires the Fund to be evaluated and given a credit rating each year. The credit rating (“Fitch Rating”) is an indicator of the Fund’s overall health and its ability to meet its debt obligations and operating costs. The credit rating is important because it allows the City to access loans for infrastructure projects more readily and at lower interest rates which results in a saving to ratepayers. The Fitch Rating considers, among other things, whether the Water Fund is consistently adjusting rates to keep up with inflation, whether it is maintaining its progress on capital improvements (maintenance and new), and its capital reserve levels. Due to the unprecedented times, during its 2020 credit evaluation, the credit rating agency understood the City’s decision to defer the adopted 2020 water rate increase temporarily. However, the credit rating agency noted in its report that future deferments of rate increases would lead to insufficient revenues needed to maintain infrastructure and could result in the Water Fund losing its AA credit rating. The Water Fund aims to maintain a minimum $10,000,000 working capital balance 1 to prepare the Fund for unforeseen emergencies. As mentioned above, the credit rating also considers reserve levels. The Utilities Department strives to anticipate upcoming capital improvement needs, but aging infrastructure occasionally leads to unexpected, emergency repairs. In recent years, working capital has been used for an emergency repair within the pipe gallery at the Water Treatment Plant and to procure an emergency generator to ensure the Water Treatment Plant can continue operating in the event of a Public Safety Power Shutoff (PSPS) event. 1 The minimum fund balance is 90 days operating & maintenance expense ($2.6 million) plus average annual capital investment ($7.2 million). Page 170 of 422 Item 7a An unreserved working capital that drops below minimum levels will jeopardize the Fund’s ability to react to emergencies and maintain its high credit rating. Staff recommends water rates be increased 3.5% effective July 1, 2021 and 3.5% effective July 1, 2022 to maintain the fund’s credit rating, to mitigate the declining capital balance, and to continue to provide reliable essential services. This action would increase the water portion of the average residential bill by $1.942 per month. Proposed Sewer Rate Increase The sewer rate increase is driven by the need to prepare for the cost of the Water Resource Recovery Facility (WRRF) upgrade, to maintain consistent sewer collection infrastructure and service, and to maintain an adequate working capital balance. Long Term Fiscal Health and Infrastructure Maintenance Based upon aging wastewater infrastructure, the Sewer Fund needs to continue replacement of sewer mainlines to reduce inflow and infiltration into the collection system, reduce scheduled maintenance, increase capacity to allow for development, and reduce wastewater overflows. The Sewer Fund is also preparing for the costs of near-term projects including the potential relocation of the Wastewater Collection shop as it is projected to be impacted by the City’s Prado Road Overpass project, operational costs associated with the WRRF upgrade, and a nearly $6 million per year WRRF upgrade debt payment. The Sewer Fund aims to maintain a minimum $15,000,000 working capital balance 3. This balance was increased over the past several years to manage the cash flow and financing requirements of the Water Resource Recovery Facility (WRRF) upgrade project. As the project nears completion, this amount will return to the $15,000,000 target. Staff recommends sewer rates be increased 3.5% effective July 1, 2021 to maintain the working capital balance for the WRRF upgrade, to prepare for the annual $6 million debt payment, address the aging wastewater collection system, and to continue to provide essential services. This will increase the sewer portion of the average customers’ bill by $2.224 per month. Protest Procedures The City sent out 19,947 written notices of the proposed assessment and ballots (see Attachment B) in late April 2021 in compliance with Proposition 218 (Prop 218). Under Prop 218, property owners and/or customers directly responsible for the payment of the rate subject to the proposed increase may submit a written protest against the proposed rate increases. 2 Based upon 5 units of consumption. 3 The minimum fund balance is 90 days operating & maintenance expense ($2.2 million) plus average annual rate- funded capital investment excluding the WRRF upgrade ($12.8 million). 4 Based upon 5 units of consumption and a sewer cap of 8. Page 171 of 422 Item 7a The protest must be submitted on the form provided by the City, received by the City Clerk at or before the June 15, 2021 public hearing, identify which rate, water and/or sewer, is being protested, and contain the address of the property receiving service. The party signing the protest must be listed on the account as the person responsible for payment of the water bill and/or the property owner. If a protest is submitted by the owner and by the tenant responsible for payment of the water bill, then one valid protest is counted for the account. If written protests are filed by a majority (50% + 1), the proposed water rate structure and rates may not be imposed. A majority of the City’s 15,794 water customers is 7,898. As of May 13, 2021, a total of 192 water and 196 sewer written protests were received by the Office of the City Clerk. All protests will need to be validated regarding property ownership and duplicate addresses. The City Clerk will provide an updated summary of the protests received at the conclusion of the public hearing on June 15, 2021. Previous Council or Advisory Body Action In May 2018, the City Council reviewed the “Comprehensive Water & Wastewater Rate Study.” In June 2020, the City Council deferred the adopted 5.5% water and 5.0% sewer 2020-21 rate increase. In December 2020, the City Council implemented the adopted 2020-21 rate increase at a lower level: 3.6% for water and 3.6% for sewer. Policy Context Water and sewer rates are subject to the requirements of Article XIIID, Section 6 of the California Constitution (Proposition 218). Public Engagement In compliance with the Proposition 218 noticing schedule, the City of San Luis Obispo mailed a notice to each property owner and water and sewer customer in the City in April 2021. The notice included the two years proposed rate increases, a summary of the purpose of the increase, and instructions on how to protest the proposed increase. Less than 800 of the 15,794 water and sewer customers had protested the proposed rate increase as of May 13, 2021. If the rate increase is approved, customers will be notified of the July 1, 2021 rate increase via utility bill insert, social media, and the City website. CONCURRENCE The City’s Finance Department concurs with the recommended action. Page 172 of 422 Item 7a ENVIRONMENTAL REVIEW Environmental Quality Act (CEQA) under Section 15273 of the CEQA Guidelines because the change in fees is not intended to fund expansion of capital projects not otherwise evaluated under CEQA. Therefore, no environmental review is required for this item. FISCAL IMPACT Budgeted: Yes Budget Year: 2022 and 2023 Funding Identified: N/A Fiscal Analysis: Funding Sources Current Rate Revenue Budget Recommended Increase Rate Revenue Budget with Increase Water Fund $22,482,863 $786,900 $23,269,763 Sewer Fund $17,395,214 $608,832 $18,004,046 Total $39,878,077 $1,395,732 $41,273,809 The proposed rate increase will increase water sales revenue by $786,900 in 2021-22 and will increase sewer sales revenue by $608,832 in 2021-22. This additional revenue was included in the water and sewer budget adopted on June 1, 2021. ALTERNATIVES 1. Do not approve implementation of the water and sewer rate increases. This is not recommended because the health of the Water and Sewer funds and their ability to provide essential services relies upon rate increases. 2. Approve a rate increase for water or sewer, not both. This is not recommended because the health of both the Water and Sewer funds and their ability to provide essential services relies upon rate increases. 3. Approve a rate increase that is less than 3.5%. This is not recommended because the health of the Water and Sewer funds and their ability to provide essential services relies upon rate increases. A lower rate increase now may drive the need for a higher rate increase in the future.

Page 182 of 422 Item 7b Department: Utilities Cost Center: 6001 For Agenda of: 6/15/2021 Placement: Public Hearing Estimated Time: 30 minutes FROM: Aaron Floyd, Utilities Director Prepared By: Mychal Boerman, Deputy Director – Water Nick Teague, Water Resources Program Manager Jennifer Metz, Utilities Project Manger SUBJECT: ADOPTION OF 2020 URBAN WATER MANAGEMENT PLAN AND WATER SHORTAGE CONTINGENCY PLAN RECOMMENDATION 1. Adopt a Resolution entitled, “A Resolution of the Council of the City of San Luis Obispo, California, adopting the 2020 Urban Water Management Plan;” and 2. Adopt a Resolution entitled, “A Resolution of the Council of the City of San Luis Obispo, California, adopting the 2020 Water Shortage Contingency Plan.” DISCUSSION Background The California Urban Water Management Planning Act (Act) is a part of California Water Code (CWC) sections 10610-10656 and 10608. The Act requires urban water suppliers to adopt and submit an updated plan to Department of Water Resources (DWR) every five years. In the Act, urban water suppliers are defined as agencies that provide water for municipal purposes to more than 3,000 customers or supply more than 3,000 acre- feet of water annually (the City meets both criteria). The City adopted its first Urban Water Management Plan (UWMP) in November 1994 and updated the UWMP in 2000, 2005, 2010, and 2016.1 The City Council adopted the 2015 UWMP by Resolution 10726 on June 14, 2016. By adopting a technically compliant UWMP, the City remains eligible for State grants, low interest loans, and other assistance. 2020 UWMP and WSCP Requirements State legislation established new requirements in 2018 for 2020 UWMPs, including standardized requirements for water shortage contingency planning and drought risk assessments. Under the State requirements, water suppliers must now plan for a dry period that lasts for five consecutive years, an increase from the previous requirement of three years. Other required elements of UWMPs include: 1 For the 2015 UWMP, the state legislature extended the filing deadline to July 1, 2016. Per the CWC, UWMPs are to be updated at least once every five years on or before July 1, in years ending in six and one, incorporating updated and new information from the five years preceding each update. Page 183 of 422 Item 7b 1. Discussion of local water supplies, with a long-term forecast for each source, including climate change. 2. Assessment of the reliability of water supply sources over a 20-year time frame. 3. Description of demand management measures, also known as conservation measures. 4. Demonstrated compliance with - Senate Bill X7-7 2020.2 5. Description of water reliability. 6. Incorporation of land use planning in water demand forecasting. 7. Preparation of a water energy analysis. 8. Inclusion of five previous years of system water losses. The State-required UWMP sections and corresponding chapters in the City’s 2020 UWMP are shown in Table 1. The City’s 2020 UWMP is provided as Attachment A to this report. Table 1 - Required Sections and Corresponding City Chapters Required Sections (by Water Code): City’s 2020 UWMP Chapter: Introduction and Lay Description Chapter 1, Introduction Plan Preparation System Description Chapter 2, Service Area and Water System Description Customer Water Use Chapter 3, Past, Current, and Projected Water Use by Sector Conservation Target Compliance System Supplies Chapter 4, Water Sources Chapter 5, Recycled Water Water Service Reliability and Drought Risk Assessment Chapter 6, Water Supply Reliability Demand Management Measures Chapter 7, Water Conservation & Demand Management Measures Plan Adoption, Submittal, & Implementation x Notices of Public Hearings included in an appendix x Checklist included in an appendix x Electronic submittal following Council Approval For 2020, the City’s Water Shortage Contingency Plan (2020 WSCP) is required to be published separately (Attachment B) from the 2020 UWMP. The 2020 WSCP is the City’s action plan for a drought or catastrophic water supply shortage. Although the State’s new requirements are more prescriptive than previous versions, many elements have been included in the City’s prior plan. As discussed in the April 13, 2021 Study Session (Attachment C), the 2020 WSCP includes six progressive stages consistent with state requirements, as shown in Table 2 page 3 of this report. Each stage corresponds to an additional ten percent shortage in available water supply. 2 Senate Bill X7-7 (Water Conservation Act of 2009) is a California state law that requires the state to reduce urban water consumption by 20 percent by the year 2020. The City’s 2020 reduction target of 117 GPCD was met and surpassed by the City. The City’s 2020 pe r capita water consumption was 94 GPCD. Page 184 of 422 Item 7b As suggested during the Study Session, an action has been added to the 2020 WSCP requiring that the City cease all water sales when entering a water shortage. A section allowing for the use of aerial imagery3-based water allotments in place of the traditional days/per week irrigation restrictions and indoor water budgets has also been added, as directed by Council. Table 2: 2020 Water Shortage Contingency Plan Water Shortage Response Stages - Quick Reference Guide STAGE WATER SUPPLY STATUS1 CITY ACTIONS Monitor 5+ years of available water supply City maintains existing water conservation staffing levels and budget that supports meeting internal water efficiency goals and regulatory requirements for water conservation, including ongoing public outreach. Watch < 5 years of available water supply (up to 10% water shortage) City increases programs that encourage voluntary water conservation including public outreach, rebate programs, and water efficient fixture giveaways. City examines available alternative water sources (groundwater expansion, recycled water filling stations, water purchase agreements, etc.), City modifies internal operations to focus on decreasing water loss and prepares for subsequent WSCP stages. City ceases any outside-City water sales/leases. Warning < 4.5 years of available water supply (up to 20% water shortage) City implements time of use irrigation restrictions (7:00 PM – 7:00 AM). City increases staffing, budget, and outreach to achieve additional voluntary conservation savings while preparing for Alert-Critical stages. Alert < 4 years of available water supply (up to 30% water shortage) City requires mandatory conservation measures including outdoor irrigation restrictions (four day a week watering) and considers a Water Offset Program for new connections. Severe < 3.5 years of available water supply (up to 40% water shortage) City implements Water Allotment Program. Water Offset Program for new connections may be increased (1.5:1 or 2:1 offset ratio). Allowable irrigation reduced to three days per week. Extreme < 3 years of available water supply (up to 50% water shortage) City continues to implement a Water Allotment Program with reduced allotment levels. Water Offset Program for new connections may be increased (1.5:1 or 2:1 offset ratio). Allowable irrigation reduced to two days per week with optional additional measures limiting turf and spray irrigation. Critical < 2.5 year of available water supply (>50% water shortage) City continues to implement a Water Allotment Program at further reduced levels (minimum for public health and safety). Irrigation no longer permitted. Water Offset Program to cease and no new connections permitted. NOTE: The City’s Water Supply Status is informed by the Water Projection Model described in Section 2 of the WSCP, Annual Water Shortage Assessment. 3 Aerial imagery are high-resolution photographs taken from an aircraft or drone. Page 185 of 422 Item 7b Should the 2020 UWMP and 2020 WSCP be approved by the City Council via the Resolutions provided in Attachment D and Attachment E, staff will return to Council later this year with an update to the City’s Water Conservation Ordinance (Chapter 13.07 of the Municipal Code) to establish the regulations and procedures for implementing the 2020 WSCP and update the ordinance to comply with newer requirements under CWC Chapter 3.3: Excessive Residential Water Use During Drought. Current City Water Supply Status Utilizing the City’s Water Projection Model as part of its water supply management, staff analyzes whether a water supply shortage is anticipated in any given year, and the severity of a shortage based on the availability of the City’s different sources of supply and water demand trends. The City uses the model to study the potential impacts of various intensities of drought conditions, including increased temperature and evaporation rates, along with decreased precipitation. Using the Water Projection Model for 2021, the City currently has more than ten years of water available. As of May 2021, the City has over 16,000 acre-feet of water in storage at Salinas Reservoir and its available balance of Whale Rock Reservoir is 15,295 acre- feet. The City requested its full contractual allocation of 5,482 acre-feet of water from Nacimiento Reservoir for 2021. Ongoing Public Outreach Regarding City Water Supplies As much of California is experiencing significant drought, the City has received many inquiries regarding water supply status and whether any specific actions are being requested of community members. As described above, City water supplies are secure and adequate to meet community needs for the foreseeable future. No water use restrictions are in place in the City or necessary at this time. To provide the community with ongoing information on the City’s current water supply availability and drought, the Utilities Department established a communications plan and calendar which outlines the methods the City will take to inform the community of current water supply conditions. This plan contains information on written communication efforts such as utility bill stuffers, the quarterly Resource Newsletter, and utilizing updates in local newspapers. Table 3 - Reservoir Storage Reservoir Volume (Acre-Feet) Percent of Capacity Salinas 16,267 68.23% Whale Rock 30,050 77.12% Nacimiento 123,365 32.64% NOTES: 1. Reservoir volumes are as of 5/13/2021. 2. City’s available balance of Whale Rock Reservoir’s total storage volume is 15,295 acre-feet. MONITOR STAGE 3 Communicate on the City’s Water Supply Status 3 Monitor Community Water Use 3 Encourage Efficient Indoor and Outdoor Water Use (Voluntary Conservation) 3 Identify and Notify Customers of Possible Leaks 3 Enforce Water Efficiency Ordinances Page 186 of 422 Item 7b The plan also outlines options for radio and social media content, and a return to public events once COVID-19 restrictions ease or are lifted. The plan focuses efforts on community groups that may be overlooked such as incoming Cal Poly students, the Spanish speaking community, and the City’s senior citizen community. Previous Council or Advisory Body Action On June 14, 2016, Council adopted the City’s 2015 UWMP by Resolution 10726. The City Council participated in a Study Session on April 13, 2021 on the 2020 Urban Water Management Plan and 2020 Water Shortage Contingency Plan (Attachment 5). Policy Context General Plan, Water and Wastewater Management Element, Program A 5.3.3 states “Prepare and update the Urban Water Management Plan every five years as required by the State.” On Short-term Water Shortages, General Plan Policy A 6.2.2, states “Mandatory water conservation measures as described in the City’s Water Shortage Contingency Plan, included in the City’s Urban Water Management Plan, may be implemented when the City's water supplies are projected to last five years or less.” Public Engagement On April 13, 2021, a Study Session was conducted to allow for community input related to the WSCP stages and associated actions. The City’s water planning documents including the 2015 Urban Water Management Plan, 2020 Water Resources Status Report, and General Plan Water and Wastewater Management Element are provided on the Utilities Department webpage, under Documents and Files, at the link below: https://www.slocity.org/government/department-directory/utilities- department/documents-and-files A complete draft of the City’s 2020 Urban Water Management Plan and 2020 Water Shortage Contingency Plan was made available on the City’s website on May 27, 2021.

Plan (UWMP) describes and evaluates current and projected water supply sources through the year 2040, describes the City’s water treatment and distribution system, reports current and projects future water demands, assesses current drought risk and the method used for future drought risk assessment, and identifies water demand management measures. The City’s 2020 UWMP was prepared in accordance with the requirements of the Urban Water Management Planning Act, as amended, and includes the following chapters: 1. Introduction 2. Water Service Area and System Description 3. Water Demand and Reduction Targets 4. Water Sources 5. Recycled Water 6. Water Supply Reliability 7. Demand Management Measures This UWMP was prepared consistent with the land uses, population projections, goals, policies, and programs in the City’s General Plan. Per new requirements for the 2020 UWMP, the City’s 2020 Water Shortage Contingency Plan (WSCP) is published as a separate volume and may be modified separately from the 2020 UWMP. 1.1 URBAN WATER MANAGEMENT PLANNING ACT The City’s UWMP was prepared in accordance with the Urban Water Management Planning Act (Act). The Act is defined by the California Water Code (CWC), Division 6, Part 2.6, and Sections 10610 through 10656. The Act requires every urban water supplier that provides water for municipal purposes to more than 3,000 connections or supplies more than 3,000 acre-feet (AF) of water annually, to adopt and submit a plan every five years to the California Department of Water Resources (DWR). Since its passage in 1983, several amendments have been added to the Act, such as those enacted in 2009 related to Senate Bill X7-7 (SB X7-7) requiring each urban retail water supplier to develop urban water use targets to help meet the statewide 20 percent water use reduction goal by 2020 and an interim ten percent goal by 2015. Chapter 4 of this Plan explains the City’s targets and implementation strategy used to meet state requirements related to SBx7-7. The Act has undergone expansion and revision reflected in the City’s 2020 UWMP and WSCP to address changing conditions in California’s water resource management. These changes focus on water use efficiency, resiliency, and impacts of climate change. New requirements include water loss reporting, analysis of energy use, and a drought risk assessment that analyzes the impact of a drought lasting five consecutive years on local water supplies. The City’s WSCP has been modified to be consistent with the required six progressive water shortage levels (10, 20, 30, 40, and 50 percent). The City’s 2020 UWMP serves as a foundational document and source of information for a Water Supply Assessment, (Water Code Section 10613), and a Written Verification of Water Supply, (Water Code Section 66473.7). Both statutes require detailed information regarding water supply availability to be evaluated prior to approval of specific large development projects. The purposes of the 2020 UWMP are to: 1. Assess current and future water use trends in the community 2. Describe the sources of water supply and the water system 3. Assess water supply reliability 4. Document the water demand management measures 5. Demonstrate compliance with SB X7-7 6. Act as a source document for the City’s General Plan Page 194 of 422 2020 Urban Water Management Plan 1-2 7. Act as a source document on the background and history of the water supply system 8. Comply with the state requirements to qualify for State grants and loans. General Plan and UWMP Interface The City’s General Plan Water and Wastewater Management Element (WWME) has been the guiding policy document for the provision of water and wastewater services to the community since 1987. The City adopted the WWME to address water and wastewater services because of the vital role these resources play in the community and the far-reaching impacts of water-related policies on community growth and character. The WWME translates the General Plan Land Use Element's capacity for development into potential demand for water supply and wastewater service. Additionally, the WWME outlines how the City plans to provide adequate water and wastewater services for its citizens, consistent with the goals and policies of other General Plan Elements. The Water Management Section of the WWME was adopted during a time when the City was experiencing water supply shortages. The policies in the original section were written in a manner to address the water scarcity issues that were facing the City in 1987. Though it has been revised and amended several times over the years (the last update was in 2019), each revision focused on how to best allocate the City’s limited water supply for the existing residences and future growth envisioned in the General Plan. 1.2 AGENCY COORDINATION The Act requires the City to coordinate the preparation of its Plan with other appropriate agencies, including other water suppliers that share a common source, water management agencies, and relevant public agencies. The following is a summary of the coordination that the City took in the preparation of this Plan. Supporting documentation is provided in Appendix I. Whale Rock Reservoir Commission Whale Rock Reservoir provides water to the City, California Polytechnic State University (Cal Poly), the California Men’s Colony, and the town of Cayucos. The Whale Rock Commission oversees the reservoir operations and is made up of representatives from the City, California Men’s Colony, and Cal Poly, as well as a representative from the State Department of Water Resources. The City provides the staff for oversight of daily operations and maintenance activities of Whale Rock Reservoir. City staff works closely with staff from the Commission members relative to water planning issues. Cayucos Area Water Organization The Cayucos Area Water Organization (CAWO) includes the three water purveyors that serve the town of Cayucos (Paso Robles Beach Water Association, Morro Rock Mutual Water Company, County Service Area 10A) and the Cayucos-Morro Bay Cemetery District. The Whale Rock Commission and the CAWO have an agreement which includes a provision to provide up to 600-acre feet of water per year from the reservoir. The agreement dates back to the period when the dam was being planned and constructed. The agreement has been amended since that time. The water provided to the CAWO is delivered from the Whale Rock pipeline to the Cayucos Water Treatment Plant operated by the County of San Luis Obispo (County). CAWO was notified that the City was updating its UWMP in March 2021. County Water Resources Advisory Committee The City is represented on the county-wide Water Resources Advisory Committee (WRAC). The WRAC is an advisory committee to the County Board of Supervisors on issues pertaining to water resources planning. The Committee holds monthly meetings to discuss water resource issues, planned projects or developments, policies, or other related issues that may have county-wide water resource impacts. Recommendations are forwarded to the County Board of Supervisors for its consideration. The Committee discusses items ranging from new water supply projects to water conservation programs and policies. An update regarding the City’s preparation and updating of its UWMP was provided to the WRAC. Review and comment by interested members was requested. Nacimiento Project Commission The County has an entitlement of 17,500-acre feet of water from Nacimiento Lake and acts as the wholesaler of this water supply. The County oversees the project that delivers water from Nacimiento Page 195 of 422 2020 Urban Water Management Plan 1-3 Reservoir to agencies participating in the Nacimiento Water Project. The current participating entities include the cities of Paso Robles and San Luis Obispo, Atascadero Mutual Water Company, Templeton Community Services District, Santa Margarita Ranch, Bella Vista Mobile home park, and County Service Area 10A (Cayucos). The Nacimiento Project Commission is made up of representatives from each of the four original participating agencies’ governing boards, as well as a representative from the County Flood Control and Water Conservation District (i.e. County Board of Supervisors). The Nacimiento Project Commission provides oversight and recommendations to the District relative to the project operations and maintenance and the associated budget. The County, as the water supply “wholesaler”, was notified that the City was updating its UWMP in March 2021. Integrated Regional Water Management Plan The County has developed an Integrated Regional Water Management Plan which included involvement and participation by the City as well as other agencies and interested individuals throughout the County. The County was notified that the City was updating its UWMP in March 2021. 1.3 PUBLIC PARTICIPATION AND PLAN ADOPTION The City encouraged public involvement in the 2020 UWMP through a City Council study session in April 2021 and a City Council public hearing in June 2021 for review of the draft document. The City further encouraged involvement of the public through correspondence and public notices. Public hearing notifications were published in The New Times (the local area newspaper). A copy of the published Notice of Public Hearing, correspondence, and the resolution of adoption are included in Appendix I. The hearing process provided an opportunity for all City water users to become familiar with the Plan and ask questions about its water resources in addition to the City’s continuing plans for providing a reliable, safe, and high - quality water supply. 1.4 PLAN IMPLEMENTATION Implementation of the 2020 UWMP is the responsibility of the City’s Utilities Department. Key staff overseeing the implementation is the Utilities Director, Deputy Director of Utilities (Water), Utilities Project Manager, and Water Resources Program Manager. Annual updates regarding UWMP implementation, as well as other City water resources issues, are provided to the City Council as part of the City’s annual Water Resources Status Report in accordance with the General Plan, Water and Wastewater Management Element, Policy A5.3.1. The 2016 through the 2020 Water Resources Status Reports are provided in Appendix II. 1.5 STANDARDIZED TABLES In response to the requirements of the CWC, standardized tables for the reporting and submittal of UWMP data were developed and are required for use in 2020 UWMPs by the State. The standardization of data tables allows for efficient data management, expedited review of UWMPs, and compilation of data for regional and statewide planning. The City will submit UWMP and WSCP data electronically to DWR using standardized tables and have included the standardized tables at the end of each chapter and Appendix IV. 1.6 COMPLIANCE CHECKLIST The City completed the checklist of specific 2020 UWMP requirements and included it in the Plan as Appendix III as requested by DWR.

Page 199 of 422 2020 Urban Water Management Plan 2-1 Chapter 2: Service Area and Water System Description 2.1 SERVICE AREA DESCRIPTION The City of San Luis Obispo is located about half-way between Los Angeles and San Francisco and has a total area of 13.2 square miles of which 13.02 square miles is land and 0.18 square miles (1.3 percent) is water. Situated in a coastal valley approximately ten miles inland from the Pacific Ocean, the City’s Mediterranean climate provides for mild and dry summers and cool winters, with an annual average of about 20 inches of precipitation. Summers are generally warm and sunny, often with morning fog from the Pacific coast. Winters are generally mild, though below freezing lows may be expected during the winter. Temperatures vary widely, with 80° F readings in January and February not uncommon. Table 1, San Luis Obispo Climate, includes the 2020 monthly evapotranspiration rate, average maximum high temperature, and average precipitation for the City of San Luis Obispo. As the City receives water from surface water reservoirs located in different watersheds, climate data specific to those surrounding the reservoirs are utilized in water management models. 2.2 SERVICE AREA POPULATION PROJECTION & OTHER DEMOGRAPHIC INFORMATION Founded in 1772 and incorporated in 1856, San Luis Obispo is one of California’s oldest communities and now serves as the County’s hub for commercial and government services. This section describes the City’s population projections, demographics information, and employment characteristics. The City’s 2020 population totaled 45,9201. From 2011 to 2020, the City grew by 502 people which was below the General Plan’s one percent growth maximum. The City’s future growth is projected to be located in the Margarita, Orcutt, Airport, Avila Ranch, and Froom Ranch specific plan areas, as well as infill and intensification of existing developed areas, such as the City’s’ downtown. The City’s total water demand has not increased at a rate that follows the rate of population growth (see Water Supply and Demand with Population chart below). In the past 30 years (from 1991 to 2020), annual water demand in the City has been as high as 6,416 acre-feet in 2007 and as low as 4,040 acre-feet in 1991, a variance of over 2,300 acre- feet. In the past ten years (from 2011 to 2020), water demand has been as high as 5,715 acre-feet and as low as 4,520 acre-feet, a variance of 1,195 acre-feet. This deviation in water demand is influenced by many factors including annual rainfall, the state and local drought declaration from 2014 to 2017, plumbing 1 Population estimates for the City of San Luis Obispo are available at the California Department of Finance website at: www.dof.ca.gov/Forecasting/Demographics/Estimates/e-1/ TABLE 1: San Luis Obispo Climate ETo (in) Average rainfall (in) Average temperature (F) January 2.44 4.98 51 February 3.36 3.51 51.5 March 3.07 3.36 54.2 April 4.63 1.44 56.3 May 6.24 0.46 60.2 June 6.32 0.12 64.6 July 6.27 0.12 67.5 August 5.87 0.02 67.6 September 4.52 0.03 66.9 October 4.30 1.22 62.9 November 3.17 1.28 56.4 December 2.64 3.93 51 Annual 52.83 20.46 59.2 Source: 1.

To be conservative in its water planning, the City uses the growth rate and population projections from the City’s General Plan Land Use Element (57,200 persons in 2035) and General Plan Water and Wastewater Management Element policy on the City’s maximum per capita water use rate under SB X7-7 of 117 gpcd, described further in Chapter 3. To comply with State requirements, the 2020 UWMP looks ahead twenty years to project water demand through 2040. As this period extends beyond the 2035 horizon of the General Plan Land Use Element, the City has assumed the population would continue to grow annually by one percent for the five years to 2040 for this UWMP. This projection yields a future population of 60,118 in 2040. Table 2 provides the City’s actual 2020 population and population projections to 2040. This approach to projecting future water demand ensures the City’s water needs will be accommodated.

City of San Luis Obispo, General Plan, Land Use Element, Table 3, 2014. 2. Population estimate for the City of San Luis Obispo is from the California Department of Finance website at: www.dof.ca.gov/Forecasting/Demographics/Estimates/e-1/ According to the US Census American Community Survey Five-Year Estimates for 2013-2017, the City’s population age demographics are 13 percent under the age of 18, 35 percent from 18 to 24, 22 percent from 25 to 44, 18 percent from 45 to 64, and 12 percent who are 65 years of age and older. The City is the civic, economic and cultural hub of the Central Coast. With these major regional employers (Table 3), the City has an estimated daytime population of up to 90,000 persons. Public sector jobs account for a sizeable portion of the job market in the City. Service and retail jobs also comprise a large percentage of employers. The City’s median household income was $56,071 (in 2019 dollars2), up from $42,461 in 2010. According to the City's 2020 Comprehensive Annual Financial Report, the top employers within and adjacent to the City are: TABLE 3: Top Employers # Employer # of Employees 1 California Polytechnic State University (Cal Poly) 3,000 2 County of San Luis Obispo 2,920 3 Dept. of State Hospitals - Atascadero 2,000 4 Pacific Gas and Electric 1,866 5 California Men’s Colony 1,517 6 Tenet Health Care Corp. 1,305 7 Compass Health 1,200 8 Lucia Mar School District 1,000 9 Mind Body 929 10 San Luis Coastal Unified School District 760 2 https://www.census.gov/quickfacts/fact/dashboard/sanluisobispocitycalifornia/PST045219 Page 201 of 422 2020 Urban Water Management Plan 2-3 As the top employer in the area, Cal Poly student enrollment is planned to grow from 21,800 students in 2018-19 academic year to 25,000 students by the 2035-36 academic year (growth of approximately 200 students per year). Cal Poly’s faculty and staff population could increase from 3,266 to 3,935 during the same time frame. While Cal Poly has its own water supply source, the City treats water for the University which is located just outside of City limits. The City is also a popular tourist destination due to its proximity to beaches and open space areas, historic downtown, and its overall vitality. The City’s tourism is at its peak during the summer. However, Cal Poly is also out of session at this time, thus reducing the overall daily population served by the City during the summer months. 2.3 WATER SYSTEM DESCRIPTION The City utilizes three surface water reservoirs to meet its potable water demand. Salinas Reservoir, located nine miles southeast of the community of Santa Margarita, has provided water to the City since 1944. Whale Rock Reservoir, located one-half mile east of the town of Cayucos, has been a water source for the City since 1961. Water deliveries from Nacimiento Reservoir, located 14 miles northwest of the City of Paso Robles, to the City began in January 2011. All surface water supplies are considered to be dependable and of high quality. Three distinct raw water transmission facilities deliver water to the City’s Water Treatment Plant from the Salinas, Whale Rock, and Nacimiento Reservoirs. The City does not currently rely on local groundwater to serve the community’s long-term water supply needs. However, the City has relied heavily on groundwater during past droughts and is planning to resume the use of groundwater pumping in the future. Additional information is provided on the City’s water sources in Chapter 4. The City is supplied recycled water from its Water Resource Recovery Facility (WRRF). In 2021, recycled water was utilized for landscape irrigation and for construction water (dust suppression, compaction, etc.). The City will be maximizing the production of recycled water with the upgrade of the WRRF, under construction in 2021. Recycled water is discussed further in Chapter 6. Figure 1 shows the location of the City’s reservoirs and conveyance pipelines. With the enactment of the Safe Drinking Water Act (SDWA) in 1974, Congress authorized the federal government to establish national drinking water regulations. Since that time, many amendments have been made to the SDWA which require additional monitoring and treatment which has resulted in increased operational costs. The following sections discuss the impacts of the current regulations on the City's water treatment facilities and potential impacts of any foreseeable amendments to the current regulations. Water Treatment The City’s Water Treatment Plant (WTP) is located on Stenner Creek Road, northwest of the Cal Poly campus. The facility was constructed in 1964 to provide treatment of surface water from Salinas and Whale Rock Reservoirs. The WTP is a conventional plant that includes ozone disinfection, coagulation, flocculation, sedimentation, and filtration. The WTP was originally designed to treat up to eight million gallons per day (mgd). In 1977, the plant was upgraded to provide 11.5 mgd of treatment capacity but actually treated up to 12 mgd for limited periods during peak summertime water demands. In 1994, the WTP was upgraded to comply with new regulations and to increase the treatment capacity to 16.0 mgd. An upgrade completed in 2008 at the WTP added additional onsite storage facilities, replaced an existing pump station, and replaced the sedimentation basin with a new ballasted flocculation process among other improvements. The addition of the Actiflo process increased the sedimentation process capacity from eight mgd to 16 mgd. This process was needed to treat the water supply from the Nacimiento Reservoir that went online in January of 2011. Since the WTP was constructed in 1964, the Safe Drinking Water Act was adopted and was significantly amended. The 1986 amendments were broad in scope and required implementation of new regulations by the U.S. Environmental Protection Agency (EPA). The Safe Drinking Water Act also required the EPA to specify criteria under which filtration is required as a treatment technique for surface supplies. On June 29, Page 202 of 422 2020 Urban Water Management Plan 2-4 1989, the EPA issued the Surface Water Treatment Rule which defined the standards for surface water treatment and had specific compliance deadlines. The purpose of the regulation is to protect the public, as much as feasible, from waterborne diseases. Waterborne diseases, most notably Giardia lamblia, Cryptosporidium, and Legionella, are most commonly transmitted by surface water contamination. For the City, the most significant issue is the regulation aimed at reducing the formation of disinfection byproducts, specifically trihalomethanes (THMs), which are a group of compounds formed during disinfection by the reaction of chlorine with naturally occurring organics. The City upgraded the WTP in 1994 to use ozone as the primary disinfectant instead of chlorine. The use of ozone provides enhanced disinfection capability to meet federal and state requirements while reducing the levels of THMs. The use of ozone also helps produce water free of objectionable taste and odor associated with algae blooms at Salinas Reservoir and meets all current, as well as anticipated regulations. The highest levels of TTHMs typically occur where water age is the greatest, such as in large water tanks with low turnover or poor mixing. With increased levels of water conservation, mixing, and turnover within some of the City’s water tanks was decreased during the recent drought. In 2020, to address the issue of increasing TTHMs, mixing, aeration, and ventilation equipment was installed at two of the City’s water storage tanks (Clearwell 2 at the Water Treatment Plant and Edna Saddle Tank). Also in 2020, the City entered into a public/private partnership with Pacific Gas and Electric (PG&E) for the Water Energy Efficiency Project at the WTP. Project components include upgrading the ozone generation system, SCADA system, plant service water, and improvements to the Transfer Pump Station. It is estimated that implementation of the Water Energy Efficiency Project will result in a reduction of energy usage of over 33 percent annually from 2019 WTP operations. The Project is scheduled to be complete in 2021. Additional information on energy use associated with water conveyance, treatment, and distribution to the community is provided in Chapter 4. City of San Luis Obispo Water Treatment Plant, 2020 Page 203 of 422 2020 Urban Water Management Plan 2-5 Page 204 of 422 2020 Urban Water Management Plan 2-6 Possible Future Regulatory Changes As analytical techniques allow for lower levels of regulated water contaminants to be detected, and as new contaminants are added to the regulatory list issued by the EPA and state regulatory agencies, there may be impacts on the City's water treatment operations. While the WTP upgrade was designed to meet the current and anticipated future water treatment standards, new regulations may require additional modifications, depending on the action levels adopted by regulatory agencies. The following are possible regulatory changes which may influence WTP operations: Regulation of total organic carbon. Could require optimizing enhanced coagulation processes, which may add a pH reduction system to the treatment process (i.e. acid feed, carbon dioxide feed, etc.). Regulation of THM sub-species. Chlorinated bromides would most likely be targeted, which would not necessarily be problematic unless the action level is extremely low. Regulation of hypochlorites. Chlorates caused by the decomposition of hypochlorite solution may require coolers or insulation be installed on holding tanks to stabilize temperature inside the tanks. This is a requirement now being considered by the State. Regulation of THMs via LRAA. THMs are now regulated on a LRAA instead of a system- wide average. This could require changing from hypochlorite to chloramines for final disinfection and/or adding aeration systems to storage tanks and reservoirs. The effect of any of the potential regulations on the City's treatment operations is dependent on the action level adopted. More technical and complicated processes may require training or hiring of personnel skilled in the maintenance of sophisticated electronic equipment and with increased knowledge in telemetry and computer programming. Potable Water Distribution System The City’s potable water distribution system delivers water from the WTP to approximately 15,700 metered customers and over 2,000 fire hydrants via 190 miles of water mains, ten treated water storage tanks, and seven pump stations. The water delivered from the WTP is split into two main distribution networks, the high-pressure side of town and the low-pressure side. The WTP has a large pump station (the Transfer Pump Station) that pumps water to the high-pressure zones which provide service to the higher elevation areas in the City. The transfer pumps take approximately half of the produced water, increase the pressure, and then provide water to Reservoir #2, Cal Poly, and other portions of the City, generally north and east of the Union Pacific Railroad tracks. Water flows by gravity directly into the lower pressure zones from the WTP's onsite clear well tanks. Water storage facilities are necessary to provide water during peak demand periods and emergency situations such as fires. The City has ten water storage facilities, seven of which are steel storage tanks ranging in size from 0.04 to 4.0 million gallons and three concrete facilities with a capacity of 0.35 to 7.5 million gallons. In 2021, the combined storage capacity is 24.425 million gallons. The goal is to provide uninterrupted water flow at adequate pressures (between 40 pounds per square inch (psi) and 80 psi) to meet all fire and domestic flow requirements and to minimize system water loss due to leakage. This pressure range will meet the needs of most irrigation sprinklers and other uses, and provide adequate pressure for fire sprinkler systems. To accomplish this, the City’s Water Distribution staff has eight major work objectives, as follows: 1. Pump station and tank maintenance 2. Water main maintenance and repair 3. Valve exercise and repair 4. Water service repair and renewal 5. Fire hydrant maintenance and replacement 6. Cross connection control 7. Underground Service Alert (USA) markouts 8. Water quality sampling Page 205 of 422 2020 Urban Water Management Plan 2-7 Because of the City’s geographic setting, pressure zones are established in the distribution system to maintain these pressure ranges. The City’s water distribution system is a complex system of 15 pressure zones and 18 pressure regulating valves (PRVs). It is unlikely this distribution pattern will change, since the WTP will continue to be the principal source of treated water for the City. Aging pipes must be replaced to avoid major service disruptions and leaks due to deterioration. Parts of the City's water system are approaching, or past, their estimated lifespan with most of the pipes being made of cast iron and ductile iron. Other pipes are made of asbestos cement, or, since the mid-1970's, polyvinyl chloride (PVC). Water pipes serve two basic functions: 1. Larger pipes or transmission mains (ranging in size from 12 to 30 inches), move large volumes of water from one portion of the City to another. 2. Smaller pipes or distribution mains (ranging in size from four inches in the older portions of the City to 12 inches) distribute water within a local area and deliver it to each property in the City. Fire protection is an important service the City provides to its residents. The fire protection system is a network of over 2,000 public hydrants and approximately 200 private hydrants. The engineering estimate for the life expectancy of these facilities is 50 years or more depending on pipe type. Pipelines are prioritized for replacement in the City’s Potable Water Distribution System Operations Master Plan. System Operation and Maintenance To retain a reliable water distribution system, preventative maintenance is performed by the City’s Water Distribution operators. Preventative maintenance is necessary to minimize water service disruption and prolong system service life. The City’s comprehensive mainline valve exercise program is beneficial to ensure proper operation of valves and minimizes disruptions to water customers during an emergency shutdown. The program assists in identifying problem areas such as broken valves, buried gatewells, and misaligned access sleeves. Identified problem areas are scheduled for repair or replacement which minimizes future water outages and ensures availability in the event of fire. The program has a goal of exercising 1,000 of the system’s estimated 5,000 valves per year, allowing for all valves in the system to be exercised every five years. Since electrical and mechanical pumping equipment consists of moving parts that are subject to wear, a comprehensive preventative maintenance program is required to prolong the useful life and avoid costly emergency equipment breakdowns Weekly inspections of the City’s pump station are performed and preventive and corrective maintenance is performed as needed. The City’s water storage tanks are an important component of the water distribution system. As a result of the storage facilities, the system's flow and pressures are improved and stabilized to better serve the customers within a storage tank’s service area. Additionally, these supplies serve as a reserve for emergencies such fires, power outages, and equipment failure at the City’s Water Treatment Plant. Regular inspections and preventative maintenance are necessary to protect the City's investment in these facilities. This includes regularly scheduled inspections and cleaning, painting and renewing protective coatings, upkeep of facility security systems, maintenance of access roads and sites, and monitoring of cathodic protection systems. Page 206 of 422 2020 Urban Water Management Plan 2-8 The service line (from the water main to the customer water meter) repair and replacement program has been a priority for the City due to the high likelihood of failure of previously installed polybutylene pipe. The City's water service lines consist of mainly copper and polyethylene pipe, but small amounts of polybutylene pipe may still exist in the system. The City removes and replaces polybutylene materials as they are discovered through routine maintenance and CIP projects. The majority of the City’s water service lines have been upgraded to copper and polyethylene material due to the longevity and durability of these two types of materials. PRVs are necessary to maintain acceptable pressure levels in both low lying and higher elevation areas of the City. These valves reduce plumbing failures and system leakage in areas that would otherwise experience high pressure. The City has 18 PRVs that are inspected and tested annually and rebuilt as needed as part of a PRV maintenance program. To ensure that fire hydrants operate correctly when needed, testing, maintenance, and repair is performed on an annual basis. It is the responsibility of the Water Distribution staff to perform all maintenance, repairs, and hydrant replacement as needed. Hydrant exercising and flushing is performed by the City in order to proactively identify hydrants that require maintenance and to improve water quality. Prior to placing a newly constructed water line into service, procedures are in place for disinfection, sampling, and testing consistent with guidelines provided by American Water Works Association and the Division of Drinking Water (DDW). The City’s Water Distribution and Water Quality Laboratory staff provide the bacteriological sampling and testing. These procedures assure that all new water lines are free of waterborne pathogens before they are placed in service, protecting the health and safety of the community. All City-related Underground Service Alerts (USA) mark outs (potable water, wastewater, recycled water, storm drains, fiber optics, and street lights) are consolidated under a single position in the Water Distribution section of the Utilities Department. Consolidation streamlined the process and increased staffing efficiencies. The management of the Underground Utility Locator is the responsibility of the Water Distribution Supervisor. The City’s distribution system is a “D4” system based on rating criteria that classifies the complexity of the system. The State has mandated certification for water distribution operators (minimum of a Grade D1). The City requires water distribution operators to attain Grade D3 certification. Continuing education is mandatory for periodic certification renewals. Contract Meter Reading In January 2015, the City executed its first water meter reading contract to address irregular billing period lengths and dates during the City’s Average Winter Water Use billing cycle. Utilizing a contract meter reading service provider made it feasible to have all City’s water meters read in one week and for billing dates to be standardized for all ratepayers. Other efficiencies gained include, that contract meter readers take pictures of water meter reads that are outside a normal range of water consumption. These pictures have saved work effort and time in both the Water Resources and Utility Billing sections. Prior to contract meter reading, Water Resources staff had to visit a property to re-read a meter if the meter read appeared outside of a normal range. Staff are now able to utilize the picture taken by the contract meter reader to inform of the potential for a water leak or another cause of high consumption. The pictures have also reduced the number of billing errors related to misread meters. The City continues to utilize a contract meter reading service provider in 2021 and looks to expand the efficiencies gained through use of these services, and associated technology, in the future.

These demand projections are used in the City’s Drought Risk Assessment provided in Chapter 6 and the annual water supply and demand assessments described in the 2020 Water Shortage Contingency Plan (annual assessments begin in 2022). This Chapter also includes description of the City’s water loss auditing program and data on water use for 2016-2019. 3.1 WATER USE BY SECTOR Existing water use in the City includes single-family and multi-family residential water users, commercial, institutional, and industrial water users (collectively “CII”), and dedicated landscape (irrigation) services. Water system loss and unbilled authorized consumption are also recorded by the City and are covered in detail in section 3.3 of this Chapter. At this time, the City does not provide potable or Title 22 recycled water for use for agricultural purposes, groundwater recharge, conjunctive use, saline water intrusion barriers, wetland or wildlife habitat, or sales/transfers/exchanges to other agencies. As shown in Table 4, water demand projections for 2025-2035 are based on estimated City population per residential growth management Policy 1.11.2 from the City’s General Plan Land Use Element updated in 2014. Projections for 2036 to 2040 are based on an extension of the City’s one percent population growth factor for that five-year period. This population growth rate limit is notably higher than the actual growth rate the City has experienced. The City has maintained a six-year average annual growth rate of 0.60 percent per year according to the Community Development Department’s residential construction permit data reported in the City’s 2020 General Plan Annual Report.1 Even the most efficiently managed water systems across the country experience unavoidable water loss from leaks, water main breaks, meter inaccuracies, and other causes. Despite efforts to minimize water loss, according to the US Environmental Protection Agency, the average water system sees a difference of about 15 percent between water produced and water sold each year. The City is working to reduce both real and apparent water losses. Water loss for 2020 and projected future water loss for 2025 through 2040 is provided in Table 4.

Such landscapes may be associated with multi-family, commercial, industrial, or institutional/government sites, but are considered a separate water use sector if the connection is solely for landscape irrigation. Commercial: A water user that provides or distributes a product or service. Industrial: A water user that is primarily a manufacturer or processor of materials as defined by the North American Industry Classifications System (NAICS) code sectors 31 to 33, inclusive, or an entity that is a water user primarily engaged in research and development. Institutional: A water user dedicated to public service. This type of user includes, among other users, higher education institutions, schools, courts, churches, hospitals, government facilities, and nonprofit research institutions. Distribution System Losses: Examples of system losses are provided in Table 5. Reporting of system losses is required by CWC Section 10631(d)(1). Unbilled, Authorized Consumption: water used for hydrant flushing, dead end waterline flushing, and other authorized but unbilled uses. Unconstrained Demand: water demand absent any water supply restrictions. 3.3 DISTRIBUTION SYSTEM WATER LOSS & UNBILLED AUTHORIZED CONSUMPTION TYPES Senate Bill 555, approved by Governor Brown in October 2015, requires retail water suppliers in California with 3,000 or more connections, or an annual water demand of over 3,000 acre-feet, to conduct an annual audit of their water distribution system to quantify water loss. The standardized audit must be validated by a certified water loss auditor to ensure data accuracy and consistency in reporting. The City submitted its first audited water loss audit to the Department of Water Resources in October 2017 for the 2016 calendar year and has submitted water loss audits annually since. The City performs annual water loss audits using the methodology outlined in the Water Audits and Loss Control Programs Manual (M36) published by the American Water Works Association (AWWA M36). The results of the annual water loss audits are submitted to the State to meet the distribution loss standards enacted by the SWRCB pursuant to Section 10631.1. Additionally, the City submits information identifying steps taken in the preceding year to increase the validity of the data entered in the final audit, reduce the volume of apparent losses, and reduce the volume of real losses. Water losses can be the result of a variety of issues such as water line leaks, meter inaccuracies, and data handling errors. This is not to be confused with unbilled authorized consumption which accounts for approved uses such as mainline flushing, fire flow testing, and other authorized uses of water that are not billed by the City. Losses which are neither billed nor metered are classified as apparent losses and include unauthorized consumption (water theft), metering inaccuracies, and systematic data handling errors. A sample of common water loss and unbilled authorized consumption types can be seen in Table 5. 2 The City compiles commercial, industrial, and institutional accounts in one category known as “CII” consistent with CWC 10608.12. Page 210 of 422 2020 Urban Water Management Plan 3-3 TABLE 5: Common Water Loss & Unbilled Authorized Consumption Types The City’s water loss volume has ranged from 11.5 percent to as low as 6.6 percent of volume supplied over the five-year period from 2016 to 2020. Reductions in water loss are the result of an increased focus on replacing aging infrastructure, including water meters which ensure accurate quantification of water use within the community. During the 2016-2020 period the City also constructed a Supervisory Control and Data Acquisition (SCADA) system which allows for ongoing monitoring of the water distribution system in order to quickly identify leaks and other system abnormalities. The AWWA M36 methodology utilizes the Infrastructure Leakage Index (ILI) as the metric to compare the performance of water suppliers, rather than percent of volume supplied. The ILI is a unit-less benchmarking metric calculated as the ratio of current losses to unavoidable losses, and is a method for comparing performance across suppliers, which accounts for the differences in how suppliers may categorize water loss. Unavoidable losses represent the theoretical lowest level of leakage, considering the water distribution system size, characteristics, and an estimation of background leakage expected in a distribution system. A well-performing system generally has an ILI score less than 3.0, indicating leakage loss is less than three times the unavoidable loss level. The City’s average ILI is 1.46 for calendar years 2016 through 2020 exceeding this standard, as shown in Table 6. Full water loss audits for 2016-2020 are available in Appendix VI.

CWC 10631 (e) (4) (B) (ii) requires that it be noted in the UWMP that the projected water use identified for 2025, 2030, 2035, and 2040 does not reflect any representation of water savings from codes, standards, ordinances, or transportation and land use plans.

The City’s projected water use figures provided in Table 4 include the projected water use for all future housing in the City, including future lower income households as defined in Section 50079.5 of the Health and Safety Code and the City’s Housing Element, as required by CWC 10631.1. Table 7 shows the quantity and category of lower income housing units from the Housing Element and estimated water use for these affordable housing units. 3.6 BASELINES AND TARGETS FOR WATER USE REDUCTION BY 2020 The Water Conservation Act of 2009 (SB X7-7) was incorporated into Division 6 of the CWC in 2009. According to the CWC, urban retail water suppliers must include in their urban water management plan the baseline daily per capita water use, along with the basis for determining the estimate, including references to the supporting data. The legislation specifically calls for using the methodologies and criteria developed by the DWR and contained in the guidance document Methodologies for Calculating Baseline and Compliance Urban Per Capita Water Use to determine compliance as required in the years 2015 and 2020. The legislation directs urban water suppliers to adopt one of the four outlined options or Target Methods in the legislation to determine their urban water use targets. As the City has invested in and implemented water conservation programs since 1988, the baseline periods outlined in the SB X7-7 used to create water use targets in 2015 and 2020 were not achievable using Target Method 1, a flat 20 percent reduction from the baseline period. After reviewing and analyzing the considerable resources required to perform Target Methods 2 and 4, the City chose Target Method 3. This method sets water use goals based on the state hydrologic region target as set forth in SB X7-7. This method represents the local climate and geography, it is important to note that the City lies completely within Central Coast Region (Region 3). The Central Coast Region’s 2020 target, expressed in gpcd, is the lowest of any region in the state. Central Coast region goals can be compared with other regions in Table 8. 3.7 UPDATING CALCULATIONS FROM 2010 UWMP In accordance with CWC 10608.20 (g), and per the recommendation of DWR, the City examined its 2020 Urban Water Use Target and will continue to utilize Method 3 (Hydrologic Region Goals); the City will not change its Target Method. Per DWR’s required use of 2010 U.S. Census data, and to correct for discrepancies between DOF’s projected populations for 2010, and actual census population data for 2010, the City updated the baseline population calculations for the 2015 Urban Water Management Plan.

Page 212 of 422 2020 Urban Water Management Plan 3-5 population corrections made slight changes to the 10-year average baseline GPCD, and the five-year average baseline gpcd, but did not change the City’s 2015 Interim, or 2020 Urban Water Use Reduction Goals as defined in Method 3 shown in Table 8. A requirement in the 2020 UWMP is completion and submission of the SB X7-7 Standardized Tables. These tables compile in-depth information about SB X7-7 and provide proof of compliance with the Water Conservation Act of 2009. The SB X7-7 Standardized Tables are provided in Appendix IV. 3.8 BASELINE PERIODS In the 2010 UWMP, the City defined both ten-year (Baseline GPCD) and five-year (Target Confirmation) baseline periods; these periods remain unchanged from the 2010 UWMP and are used to establish the 2020 Target Goal, along with baseline period per capita figures for water use reduction. Table 9 defines the ten-year baseline period from 1997-2006 and the five-year baseline period from 2004-2008. The methodology used to establish ten-year and five-year baseline periods is included below. Through analysis of the quantity of total water deliveries made up of recycled water in 2008, it was discovered that the City did not meet the ten percent threshold required to use a 15-year baseline period, leading the City to follow CWC 10608.12 (b) (1) guidance to use a ten-year baseline period. The City’s ten-year baseline period of 1997 to 2006 and corresponding populations, annual gross water use, and daily per capita water use (gpcd) calculations provided by DWR can be viewed in SB X7-7 Table 1 in Appendix IV. In accordance with CWC 10608.12 (b) the City calculated its five-year baseline average period water use. Ranging from 2004-2008, the five-year time frame was selected in accordance with Methodology 3: Base Daily Per Capita Water Use. TABLE 9: Baseline Period Ranges 1 If the 2008 recycled water percent is less than ten percent, the first baseline period is a continuous ten- year period. If the amount of recycled water delivered in 2008 is ten percent or greater, the first baseline period is a continuous ten- to 15-year period. 2 The ending year must be between December 31, 2004 and December 31, 2010. 3 The ending year must be between December 31, 2007 and December 31, 2010. NOTE: SB X7-7 Table 1, see Appendix IV. Baseline Parameter Value Units 10- to 15- year baseline period 2008 total water deliveries 6,359 Acre Feet 2008 total volume of delivered recycled water 90 Acre Feet 2008 recycled water as a percent of total deliveries 1.41 Percent Number of years in baseline period 1 10 Years Year beginning baseline period range 1997 Year ending baseline period range 2 2006 5-year baseline period Number of years in baseline period 5 Years Year beginning baseline period range 2004 Year ending baseline period range 3 2008 As defined by CWC 10608.12 (b), “base daily per capita water use” is defined as: (1) The urban retail water supplier’s estimate of its average gross water use, reported in gallons per capita per day and calculated over a continuous 10-year period ending no earlier than December, 31 2004, and no later than December 31, 2010. Or (2) For an urban water supplier that meets at least 10 percent of its 2008 measured retail water demand through recycled water that is delivered within the service area of urban water supplier or its urban wholesale water supplier, the urban water supplier may extend the calculation described in paragraph (1) up to an additional five years to a maximum continuous period ending no earlier than December 31, 2004, and no later than December 31, 2010. Page 213 of 422 2020 Urban Water Management Plan 3-6 3.9 SERVICE AREA POPULATION For the 2020 UWMP, the City’s service area boundaries have been found to correspond by 95 percent or more with the city limits. This correspondence allows the City to use Department of Finance population estimates as defined in DWR’s Urban Water Management Guidebook. These population estimates were updated from the 2015 UWMP to reflect differences in population between the Department of Finance projections and the 2010 Census. Population data for each of the baseline years can be found in Table 11. 3.10 GROSS WATER USE As defined by CWC 10608.12 (g), “Gross Water Use” means the total volume of water, whether treated or untreated, entering the distribution system of an urban water supplier, excluding all of the following: (1) Recycled water that is delivered within the service area of an urban water supplier or its urban water wholesale water supplier (2) The net volume of water the urban retail water supplier places into long term storage (3) The volume of water the urban retail water supplier conveys for use by another urban water supplier (4) The volume of water delivered for agricultural use, except as otherwise provided in subdivision (f) of Section 10608.24. The City’s gross water use is exclusively comprised of water entering the distribution system from four sources: Salinas Reservoir, Whale Rock Reservoir, Nacimiento Reservoir, and groundwater. Per Methodology 1: Gross Water of the methodologies document, recycled water delivered within the service area is excluded from the calculation of gross water. Water suppliers are not required to report their recycled water use, nor demonstrate any reduction in recycled water use for the purposes of SB X7-7. For detailed information on volume of water that entered the distribution during the baseline periods and in 2020, please refer to Table 10.

Page 214 of 422 2020 Urban Water Management Plan 3-7 3.11 BASELINE PER CAPITA WATER USE Daily Per Capita Water Use was calculated for the ten-year, five-year, and 2020 compliance year periods (see Table 11). The ten-year average baseline per capita water use was calculated at 123 gpcd while the five-year average baseline per capita water use totaled 124 gpcd. The 2020 compliance year figure of 94 gpcd is low due to continued conservation efforts by the community and decreases in system water losses. 3.12 2015 AND 2020 URBAN WATER USE TARGET Per CWC 10608.20 (e), water retailers were directed to calculate a 2020 urban water use target, and an interim urban water use target in their 2015 Urban Water Management Plan. This target is referred to as the 2020 target. As detailed in section 3.6, the City used Target Method 3 to comply with SB X7-7. As noted in Table 8, the Central Coast Hydrologic Region was required to reduce the regional goal of 123 gpcd by five percent, effectively establishing a 117 gpcd goal for the City. As a requirement of CWC 10608.22, an urban water supplier’s per capita daily water use reduction shall be no less than five percent base per capita water use as defined in the five- year baseline average. This calculation, and compliance is confirmed Table 12. The Central Coast Region target goal of 117 gpcd requires a six percent reduction in per capita water use, thus satisfying the requirement for at least a five percent reduction. All information and DWR tables used to develop baselines and the resulting 2020 target can be viewed in Appendix IV. The summarized information in Table 14 is provided at the recommendation of DWR for quick verification of compliance with the Water Conservation Act of 2009.

Low potable water usage and gallons per capita per day figures in 2020 are a result of a continued focus on efficient water use, largely from measures implemented in during the 2012-2015 drought. Beginning in 2015, potable water usage and gallons per capita per day figures were significantly reduced due to conservation efforts, prolonged drought, and Governor Brown’s April, 2015 drought declaration, requiring a statewide 25 percent reduction in potable water use. TABLE 14: 2020 SB X7-7 Compliance In accordance with statewide reduction efforts and Executive Order B-29-15, the City was required to reduce residential gallons per capita daily (RGPCD) consumption by 12 percent from 2013 usage levels. Due to a long history of successful conservation strategies, along with strong community support, the City surpassed both its drought reduction goals and its SB X7-7 water use reduction goals.

Source: City of San Luis Obispo, Utilites Department, 2021. 3.14 INFLUENCE OF CLIMATE CHANGE ON WATER DEMAND The potential influence of climate change on water demand is one of the factors that the City considers when using making its water demand projections, such as the potential for greater landscape irrigation demand due to a reduction in rainfall. The City recognizes the impact of rainfall variability on water demand. During years where the City receives less than average rainfall, irrigation can continue into late in the year (November and December) or resume early in the year (March and April). Table 16 provides the City’s Calendar Year 2020 monthly potable and recycled water demand, illustrating the variability of monthly water demand due to landscape irrigation. Climate change research suggest that water demand for agriculture will be affected more heavily than will demands in other sectors. However, the City does not supply any water for agricultural irrigation. Although the City has seen increased water demand for landscape irrigation during years with less rainfall, the City has also seen a shift in the types of landscapes being installed as part of new development and landscape retrofits since the 2012-2015 drought. The use of drought-tolerant landscaping and more efficient landscape design should reduce year-to-year variations in water use that are driven by variations in weather. 122 120 129 125 119 106 101 107 113 105 92 88 97 91 90 94 117 0 20 40 60 80 100 120 140 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020 2020 TargetGallons per Capita per Day (GPCD)Year TABLE 15: Average Gallons Per Capita Per Day (GPCD) Timeframe GPCD 10-Year Average (2011-2020) 98 5-Year Average (2016-2020) 92 Pre-drought Average (2006-2011) 117 Page 217 of 422 2020 Urban Water Management Plan 3-10 Reference Chapter 6 for a detailed discussion of climate change considerations related to the City’s water sources and the City’s Drought Risk Assessment.

Page 221 of 422 2020 Urban Water Management Plan 4-1 Chapter 4: Water Sources As the sole water purveyor within the City limits, the City maintains control over water quality, distribution, and service to the community, as well as ensuring consistency with the General Plan policies and goals. The City’s General Plan Water and Wastewater Management Element (WWME) was originally adopted in 1987. Policy A2.2.1 states “The City shall utilize multiple water resources to meet its water supply needs.” Having several sources of water avoids dependence on any one source that may not be available during a drought or other water supply reduction or emergency. There is generally greater reliability and flexibility if sources are of different types (such as surface water, recycled water, and groundwater) and if the sources of one type are in different locations (such as reservoirs in different watersheds). Consistent with the WWME, the City obtains water from Salinas Reservoir (Santa Margarita Lake), Whale Rock Reservoir, Nacimiento Reservoir, and recycled water from the City’s Water Resource Recovery Facility (WRRF). Groundwater was utilized in the past and is considered an available supplemental water supply. The following sections discuss each of the City’s water sources; the reliability of each water source is discussed in Chapter 6. 4.1 SALINAS RESERVOIR The Salinas Reservoir (also known as Santa Margarita Lake) is located on the upper Salinas River, approximately nine miles southeast of the community of Santa Margarita. The project was originally built by the War Department to ensure an adequate water supply for Camp San Luis Obispo, as well as the City of San Luis Obispo. The dam and appurtenances were declared surplus by the War Department on April 14, 1947 and the U.S. Army Corps of Engineers assumed responsibility for the facilities. On July 11, 1947, the Corps entered into an agreement with the San Luis Obispo County Flood Control and Water Conservation District (District) for the operation and maintenance of the dam and related facilities. The City has an agreement with the Corps for use of the reservoir, as well as a water rights permit to divert water from the Salinas River for storage within the reservoir. Operation and Distribution Salinas Reservoir is formed by a concrete arched dam. Immediately following construction, the reservoir had an estimated storage capacity of 24,000 acre-feet, surface area of 793 acres, and a drainage area of 112 square miles. As a result of siltation since the original construction, the reservoir capacity has been reduced. A 1990 analysis conducted by the County of San Luis Obispo indicates that the siltation rate is on the order of 40 acre-feet per year. The estimated loss in storage capacity for Salinas Reservoir between 1990 and 2010 was 800 acre-feet. Water is conveyed from Salinas Reservoir through 48,700 feet (9.2 miles) of 24-inch diameter reinforced concrete pipe to a three million gallon regulating reservoir at the Santa Margarita booster pump station near the northerly base of Cuesta Grade adjacent to Highway 101. The pipeline is designed to flow by gravity from the Reservoir to the regulating reservoir when the lake level is above the elevation of 1,267 feet. A booster pump station at the base of the dam, consisting of two horizontal centrifugal pumps, is capable of maintaining the rated flow of 12.4 cubic feet per second (cfs) when the water surface elevation falls below 1,267 feet. Three electrically driven, horizontal centrifugal pumps at the Santa Margarita booster station pump water through 6,810 feet of 24-inch diameter reinforced concrete pipe to the entrance portal of the Cuesta Tunnel, which runs 5,327 feet through the mountains near Cuesta Grade. From the outlet portal of the tunnel, water is conveyed through an 18-inch diameter steel pipeline a distance of 5,133 feet to the Whale Rock Reservoir, August 2019. Page 222 of 422 2020 Urban Water Management Plan 4-2 City's turnout point. From the turnout, an 18- inch diameter pipe runs 4,180 feet to the site of Reservoir #2 on Stenner Creek Road. From there, a pipeline that varies from 24-inches to 30-inches in diameter conveys the water by gravity to the water treatment plant 5,930 feet downstream. The operation and maintenance of the dam and water conveyance system (to the City’s turnout) are the responsibility of San Luis Obispo County Flood Control and Water Conservation District. The City pays all operating, maintenance, and capital costs associated with the reservoir and transmission system (excluding costs associated with recreational activities at the Lake). 4.2 WHALE ROCK RESERVOIR Whale Rock Reservoir is located on Old Creek approximately one-half mile east of the community of Cayucos. The project was planned, designed, and constructed under the supervision of the State Department of Water Resources. Construction took place between October 1958 and April 1961. The reservoir is jointly owned by the City, the California Men's Colony, and the California Polytechnic State University at San Luis Obispo (Cal Poly). These three agencies form the Whale Rock Commission which is responsible for operation and administration of the reservoir and associated water deliveries. Day-to-day operation is provided by the City. The City owns 55.05 percent of the water storage rights at the reservoir. The remaining water storage rights are apportioned between the two State agencies with Cal Poly owning 33.71 percent and the California Men’s Colony owning 11.24 percent. Operation and Distribution Whale Rock Reservoir is formed by an earthen dam and was able to store an estimated 40,662 acre-feet of water at the time of construction. The dam is 266 feet tall with a crest length of 850 feet and crest width of 30 feet. The top of dam elevation is 232.2 feet. The Reservoir covers an area of 600 acres. In 2021, the maximum storage capacity is 38,967 acre-feet. Over the life of the Whale Rock Reservoir and dam, the lake has filled to capacity and the spillway has been used 12 times, last spilling in 2005. The project facilities consist of a 30-inch pipeline, two pumping stations, over two miles of trails and a fishing access facility, a maintenance facility and office, and a structure used as a private residence. City staff is responsible for ongoing maintenance and operation of the reservoir, including the inlet and outlet structures, reservoir structural instrumentation, access roads, daily reservoir level readings and climatological data, reservoir patrol and security, pipelines and pumping stations, water meters, cathodic protection systems, and other associated duties. Staff also monitors public access to the lake. The conveyance system delivers water from the reservoir to the Whale Rock Commission member agencies located between the reservoir and the City. Outlets from the pipeline exist for water deliveries to Chorro Reservoir and water treatment plant (operated by the California Men's Colony), Cal Poly State University, the Cayucos water treatment facility and the City's Water Treatment Plant. In addition, water can be delivered to the Dairy Creek Golf Course under terms of an agreement between the California Men’s Colony and the County of San Luis Obispo. The Whale Rock pipeline is approximately 17 miles long, connecting the reservoir to the member agencies, and terminating at the City's Water Treatment Plant. The design capacity of the pipeline is 18.94 cubic feet per second (approximately 8,500 gallons per minute). The line consists of modified pre-stressed concrete cylinder pipe at most locations. Cement mortar lined steel pipe is used at creek crossings and junctions. Salinas Dam spillway, February 2019. Page 223 of 422 2020 Urban Water Management Plan 4-3 The pipeline has surge protection consisting of eight-inch, globe type, diaphragm-actuated pressure relief valves which protect the line from excessive pressures. The cathodic protection system consists of sacrificial anodes and test stations located in areas subject to galvanic corrosion. Previous inspections made during routine maintenance and repairs indicate the pipeline to be in good condition. Two pump stations transmit the water along the pipeline to member agencies. The first pump station is located in Cayucos at Chaney Way (elevation 44 feet). The second station is located near Camp San Luis Obispo, approximately six miles southeast of Morro Bay (elevation 181 feet). Each station has five-200 horsepower pumps capable of delivering various flow rates requested by member agencies. Upgrades to both pump stations, which included the addition of two pumps at each station, were completed in August 1993. In 2018, the City contracted with HDR Engineering, Inc. for inspection and assessment of the 850-foot long Whale Rock Dam spillway. The investgation included: 1. Review of design, construction, inspection, analysis, operation and maintenance, and geologic information, as provided by City. 2. Detailed visual, non-destructive inspection of the spillway slabs and walls from upstream of the spillway crest to downstream of the stilling basin. 3. Video/camera inspection of accessible outfall drains and heel drains. 4. Geologic inspection of foundation material adjacent to the spillway. 5. Evaluation of original spillway design versus a modern spillway design. 6. Evaluation of operations, inspection, and surveillance practices. 7. Evaluation of performance of previous repairs. A report was completed in March 2019 with recommendations including maintenance and repair activities for the drainage system and further engineering investigations. The City and its Whale Rock partners, Cal Poly and the California Men’s Colony, will implement corrections as recommended by the California Department of Water Resources, Division of Safety of Dams. Whale Rock trail. Whale Rock Dam Spillway. Page 224 of 422 2020 Urban Water Management Plan 4-4 Operating Agreements Several agreements establish policies for the operation of the Whale Rock system and actions of the member agencies. A brief description of the existing agreements follows: A) Agreement for the construction and operation of the Whale Rock Project, 1957, set forth the project's capital cost distribution to the member agencies. B) A supplemental operating agreement, 1960, established the Whale Rock Commission and apportioned the operating costs. C) Downstream water rights agreement (original 1958 agreement was amended and replaced with a new agreement in April 1996) established water entitlements for adjacent and downstream water users. The downstream water users (Cayucos Area Water Organization or CAWO) affected by this agreement consist of three public water purveyors and the cemetery. In addition to the agencies, water entitlements were identified for separate downstream landowners; see Table 17. D) A decision and order by the Fish and Game Commission of the State of California, October 24, 1964, required the Whale Rock Commission to stock the reservoir with 17,500 rainbow trout (between six and eight inches long) each year. The State Department of Fish and Game has directed that no fish be planted in the reservoir to protect the existing fish population in the reservoir (landlocked steelhead). E) Superior Court decision #36101, 1977, required the Whale Rock Commission to allow public entry to the reservoir for fishing. In 1981, construction was completed on access trails and sanitary facilities at the reservoir, and public fishing began at the lake. F) An agreement for water allocation and operational policy between the agencies forming the Whale Rock Commission. The agreement established the accounting procedures to allow each agency to carry over excess or deficit water each year. The operating policies were most recently amended in 2014 to allow agencies to utilize their water supplies in the reservoir as needed by their agency. G) An agreement between the Whale Rock Commission and the California Men's Colony, 1990, to establish maintenance and operation criteria for the Chorro Booster pumps. The Chorro Booster pumps were installed by the Commission on the California Men's Colony turnout from the Whale Rock line to reduce system pressures required to provide full flow to the California Men's Colony water treatment plant. Pump station maintenance, per the agreement, is the responsibility of the California Men's Colony. H) An agreement between the Whale Rock Commission and the County of San Luis Obispo for connection to the Whale Rock pipeline, 1995, allowed a pipeline connection to deliver water to the Dairy Creek Golf Course. Typically, the golf course uses reclaimed water from the California Men’s Colony Wastewater Treatment Plant. Water from Whale Rock Reservoir can be delivered when reclaimed water is not available under the terms of the agreement. 30-inch Whale Rock Pipeline Repair Conducted in June 2017 TABLE 17: Whale Rock Reservoir Downstream Entitlement Downstream Water Users Allocation Cayucos Area Water Organization 600 Paso Robles Beach Water Association 222 Morro Rock Mutual Water Company 170 County Water District #10A 190 Cayucos-Morro Bay Cemetery District 18 Mainini 50 Ogle 14 Total Downstream Entitlement: 664 NOTE: Allocations are in acre-feet per year.

The agreement allowed the installation of the State Water pipeline at seven locations within the existing Whale Rock pipeline easement. J) An agreement, updated in 2018, for exchange of water between the City of San Luis Obispo and the San Luis Obispo County Service Area No. 10A. The agreement allows for the exchange of up to 50 acre-feet per year of Nacimiento water for water from Whale Rock Reservoir.

SOURCE: Nacimiento Water Project Initial Watershed Sanitary Survey, 2014. Pipeline Condition Assessments During 2019, pipeline condition assessments were completed for the Whale Rock Reservoir and Salinas Reservoir (Santa Margarita Lake) water transmission pipelines. The condition assessments used free- swimming electromagnetic inspection technology, shown in the image below, to locate and identify segments of the pipeline in need of repair. Over 16 miles of 30-inch transmission pipeline from Whale Rock Reservoir was analyzed. The assessment found that 2,610 segments had no abnormalities, and 25 segments had varying deficiencies (broken bar wraps or cylinder wall loss). The Salinas pipeline condition assessment analyzed 1.25 miles of pipeline originally installed in 1940s. Results of the assessment were described in a May 2019 report revealing 222 of the total 236 segments had no abnormalities, and 14 segments had varying deficiencies. Funding is programmed to address the identified pipeline deficiencies in the next few years. Conceptual image of Electromagnetic Inspection Technology used to assess the Whale Rock and Salinas Reservoir transmission pipelines. Page 226 of 422 2020 Urban Water Management Plan 4-6 4.3 NACIMIENTO RESERVOIR In 1959, the San Luis Obispo Flood Control and Watershed Protection District entered into an agreement with Monterey County Flood Control and Water Conservation District (now Monterey County Water Resources Agency) to secure rights to 17,500 acre-feet of water per year from Nacimiento Reservoir. Nacimiento Reservoir is located entirely within San Luis Obispo County, California (County), and was built by Monterey County Flood Control and Water Conservation District who continues to control reservoir ownership and operations. Nacimiento Reservoir has a storage capacity of 377,900 acre-feet and serves the purpose of abating seawater intrusion in the groundwater aquifers of the Salinas River Valley. The Nacimiento Reservoir also provides flood protection and is a source of water supply for groundwater recharge for the Salinas Valley. 1,750 AFY of the County’s entitlement have been designated for uses around the lake, leaving 15,750 AFY for allocation to other areas within the County of San Luis Obispo. The “dependable yield” from Nacimiento Reservoir is the contractual amount of water that the City has rights to from Nacimiento Reservoir. The original amount contracted for was 3,380 acre-feet per year. Engineering studies, environmental impact reports, dependable yield analyses, and preliminary design reports were undertaken in an effort to meet the various water needs within the County. In 2004, the County requested interested agencies to approve the contractual agreements for participation in the Nacimiento Project. The four initial project participants included the cities of San Luis Obispo and Paso Robles, the Atascadero Mutual Water Company, and the Templeton Community Services District. All of these agencies executed participation agreements with San Luis Obispo County for entitlements of water which totaled 9,630 acre feet. On June 29, 2004, the City Council authorized participation in the Nacimiento Water Project for the delivery of the original 3,380 acre-feet of water. In 2004, the County Service Area 10A in Cayucos became a project participant (25 AFY). The County began construction in 2007 on a 45-mile pipeline project to deliver water from the Nacimiento Reservoir to participating agencies and cities. The facilities consist of a multi-port intake structure, three pump stations, three storage tanks, 45 miles of pipeline, four turnouts, a control center, and a Supervisory Control and Data Acquisition (SCADA) and Project control system. The Project budget was $176-million, including design, construction, construction management, environmental permitting, and right-of-way. Pipeline construction and related water delivery facilities were completed in the fall of 2010 with water deliveries to the City beginning in January of 2011. In March 2016, the City Council approved the addition of 2,102 AFY from Nacimiento Reservoir to the City’s secondary water supply. This addition brought the City’s total Nacimiento Reservoir Allocation to 5,482 AFY. Secondary water supplies are used to meet short-term losses to the City’s water supply due to events such as drought, pipeline maintenance, and repair of infrastructure. With uncertainty of future climatic conditions, regulation and aging infrastructure, the additional supply of Nacimiento water to the City’s portfolio reduces pressure on use of water supplies in the Whale Rock and Salinas reservoirs. It would serve to extend these stored supplies during future critical water shortage periods. San Luis Obispo County operates, maintains, and administers capital improvement projects for the water delivery system from Nacimiento Reservoir to participating agencies (currently the cities of Paso Robles and San Luis Obispo, Atascadero Mutual Water Company, Templeton Community Services District, County Service Area 10A [Cayucos], Santa Margarita Ranch, and Bella Vista Mobile Home Park).

Page 227 of 422 2020 Urban Water Management Plan 4-7 Project Commission provides oversight to project operations, maintenance, and the project budget. The Commission is made up of representatives from each of the four founding agencies’ governing boards and a County Representative who is a member of the County Board of Supervisors who also sits on the Board of Directors for the Flood Control District. 4.4 GROUNDWATER The principal source of groundwater for the City is the San Luis Obispo Valley Groundwater Basin (Basin). The Basin is oriented in a northwest-southeast direction and is composed of unconsolidated or loosely consolidated sedimentary deposits. It is approximately 14 miles long and 1.5 miles wide. It covers a surface area of about 12,700 acres (19.9 square miles). The Basin is bounded on the northeast by the relatively impermeable bedrock formations of the Santa Lucia Range, and on the southwest by the formations of the San Luis Range and the Edna fault system. The bottom of the SLO Basin is defined by the contact of permeable sediments with the impermeable bedrock Miocene-aged and Franciscan Assemblage rocks. The Basin is commonly referenced as being composed of two distinct valleys, with the San Luis Valley in the northwest, providing water to the City of San Luis Obispo, and the Edna Valley in the southeast providing water to unincorporated areas of the county and large agricultural operations. FIGURE 5: San Luis Obispo Valley Groundwater Basin The City's major source of water was groundwater and surface water local creeks until 1944 when the City began to use water from Salinas Reservoir. In 1943, the City pumped 1,380 acre-feet of groundwater. Groundwater was used again during the summer of 1948, when 440 acre-feet was pumped. From that point on until 1989, most groundwater in the City was used by agriculture and very little was used for domestic consumption. With the onset of the drought in 1986, resulting in decreasing surface water supplies, the City activated groundwater wells in 1989 to meet the City's water demand. In November 1992, nitrate levels in the Auto Page 228 of 422 2020 Urban Water Management Plan 4-8 Park Way Well exceeded State standards, so the well was taken out of service. In April 2015, the City stopped utilizing the Pacific Beach Well on Los Osos Valley Road for potable water purposes due to more stringent regulations for hexavalent chromium. The Fire Station #4 Well had been offline due to remediation of soil contamination at the adjacent Shell service station and is also currently offline due to hexavalent chromium. Like surface water, groundwater must meet the standards set in the Safe Drinking Water Act. Water quality analysis in 1989 indicated that advanced treatment was needed on the now decommissioned Dalidio and Auto Park Way Wells due to unacceptable levels of tetrachloroethylene (PCE). Carbon adsorption units were placed on each well to provide necessary treatment and were granted approval for domestic consumption by the State of California, Department of Public Health (now the State Water Resources Control Board, Division of Drinking Water (DDW)). The 1996 Amendments to the SDWA required the EPA to develop regulations that require disinfection of ground water systems to protect the public health. In 2006, the Groundwater Rule was adopted to further protect against waterborne illness due to fecal and E. Coli contamination in public water systems that use groundwater supplies. In the 2010 update of the WWME, the City eliminated groundwater from the water supply calculation as a basis for meeting long-term water demands. The decision was based on the water quality and availability issues which deemed groundwater as a potentially unreliable source. Consistent with Policy A 3.2.3 from the City’s WWME, the City does not rely on groundwater to meet long-term water demand. The City will utilize groundwater in the future, as the resource is needed, and plans to use well-head treatment to ensure the water quality is appropriate for potable purposes. Current groundwater use includes one non-potable well located within the City’s Corporation yard and two irrigation wells used at the City’s Laguna Golf Course. The City's drinking water wells are offline and not used to meet any of the City’s water needs. The Corp Yard well was established during the drought of 1987- 91 to serve as an alternative source of water for construction-related activities prior to the City’s recycled water program. The City placed limitations on the use of the Corp Yard well in 2015 and it is only available for municipal purposes, such as street sweeping and of City-owned trees. Table 19 shows the City’s groundwater production for 2016 through 2020. These production amounts do not include agricultural and private groundwater pumping by non-City entities. Table 19 does not identify any City groundwater production in the term examined as part of this UWMP. Sustainable Groundwater Management Act In the future, the City plans to use groundwater to balance of its overall water supply portfolio as the use of groundwater would contribute to resiliency in the City’s water supply portfolio. The Sustainable Groundwater Management Act (SGMA) is a statewide law that requires Groundwater Sustainability Agencies (GSA) to adopt groundwater management plans that outline actions needed to return groundwater basins to sustainable levels of pumping and recharge. In May 2017, the City Council approved Resolution 10796 authorizing the City to become a Groundwater Sustainability Agency (GSA) for the San Luis Valley Groundwater Basin for the area that lies beneath and within the City’s jurisdictional boundaries. In February 2019, the City Council, acting as the San Luis Valley Basin – City of San Luis Obispo Groundwater Sustainability Agency, approved the Notification of Intent to initiate development of a Groundwater Sustainability Plan (GSP) for the San Luis Obispo Valley Groundwater Basin. While the Basin as a whole has been identified to be in overdraft and is listed as a high priority basin under SGMA, the basin has two distinct, largely hydrologically disconnected sub areas that are experiencing drastically different conditions from one another. The area underlying the City of San Luis Obispo, from which the City historically pumped groundwater, has experienced no ongoing groundwater level decline and is estimated to have a groundwater surplus of 700 AFY. The area to the southeast of the City, generally within the Edna Valley area, has experienced ongoing groundwater level decline and is estimated to have more than 1,000 AFY in over-pumping of groundwater resources. The San Luis Valley Groundwater Basin is not an adjudicated basin. Page 229 of 422 2020 Urban Water Management Plan 4-9 The City is working in collaboration with the County of San Luis Obispo GSA to create a single Groundwater Sustainability Plan (GSP) that provides full coverage of the San Luis Valley Groundwater Basin where each GSA is responsible for ensuring compliance with SGMA for their respective portions of the groundwater basin. To get additional information, to sign up for the interested stakeholder email list, or to see materials for past or upcoming meetings related to the GSP development, interested parties are encouraged to visit www.slowaterbasin.com. The San Luis Valley GSP must be submitted to California Department of Water Resources (DWR) by January 31, 2022. 4.5 FUTURE WATER PROJECTS AND DESALINATED WATER OPPORTUNITIES The City has not identified the need for additional water supplies to meet potable water demand for the term of this UWMP. However, as described further in Chapter 5, construction of the upgrade of the WRRF is underway in 2021 to accommodate General Plan buildout and maximize recycled water production. The upgrade will enable the City to pursue potable reuse opportunities in the future, including opportunities to augment groundwater supplies with recycled water. In July of 2020, the City received a nearly $2 million planning-phase grant, funded through Proposition 1, to study PCE contamination of the groundwater basin. A detailed understanding of the extent of PCE contamination and remediation options are necessary steps in fully utilizing the City’s groundwater pumping opportunities. The planning phase work will continue into 2022. The City is planning to apply for an implementation-phase grant to fund necessary capital improvements to put an additional groundwater well into service. This work enhances the City’s ability to extract, treat, and utilize groundwater to meet a portion of the City’s potable water demand. Desalination is a viable technology which is not rainfall dependent. Desalination activities can have significant negative environmental impacts and significant energy requirements which drive up the cost of desalinized water. The major disadvantages of desalination are the cost, potential for environmental impacts, and significant energy demand. Desalination is currently being used or considered for use by multiple agencies in California and could potentially be a water supply consideration in the future if the City’s current supplies prove to be inadequate or insufficiently resilient. Advances in desalination technology and cost reductions may create opportunities to utilize this resource in the future. 4.6 WATER SUPPLY SUMMARY Tables 20 and 21 provide information for each source of water utilized by the City in 2020. The City utilized water from its multi-source supply in a conjunctive manner. The City intends use its contractual water supply from Nacimiento Reservoir first, with Whale Rock and Salinas used as needed to meet the City’s overall potable water demand. In the twenty years projected by this UWMP through 2040, the City assumes it will continue to use these water supplies in this coordinated manner. Recycled water was used at over 50 metered locations for landscape irrigation and construction water uses in 2020.

The agreement provides a general framework for exchanging water between agencies in the event of emergencies or other water disruptions. The agreement is voluntary based on each agency’s ability to assist at any point in the future. The City is also a member of the California Water/Wastewater Agency Response Network (CalWARN). This organization functions in coordination with the State Office of Emergency Services (OES) to support and promote statewide emergency preparedness, disaster response, and mutual assistance matters for public and private water and wastewater utilities. 0 20 40 60 80 100 120 140 160 180 2006 Exchange Agreement 2018 Updated Exchange AgreementAcre FeetNacimiento/Whale Rock Exchange Agreement Page 231 of 422 2020 Urban Water Management Plan 4-11 The San Luis Obispo County Service Area No. 10 (Cayucos) and the City have a water exchange agreement which was originally executed in October of 2006. In 2018, Following the full allocation of Nacimiento Reservoir, City and County staff recognized the need to update the Exchange Agreement to align with the entitlements in the provisions of the full allocation of Nacimiento. The updated agreement reduces the amount of water that could potentially be delivered to CSA 10 from 160 acre-feet, identified in the 2006 agreement, to 50-acre feet per year, coinciding with the total County Service Area No. 10A and Bella Vista Mobile Home Park entitlement. The updated Exchange Agreement, finalized in July 2018, facilitates a successful partnership between the City and County to meet regional water needs and minimizing cost and potential environmental issues. 4.8 ENERGY USE The 2020 UWMP is required to include energy information. For purposes of analyzing the energy used by the City to deliver potable water to the community in 2020, potable water management is divided into raw water conveyance, water treatment, and water distribution. Because the City conveys, treats, and distributes water as a retail provider to Cal Poly by agreement, the energy consumed for each water management process is calculated as a percentage of the total energy use for the process, equal to the City's portion of the water. The energy used to provide potable water to the community is summarized in Table 23. The energy used to provide recycled water to the community is described in Chapter 5 and summarized in Table 29. Raw Water Conveyance As described earlier in this Chapter, the City utilizes raw water from three surface water reservoirs (Salinas, Whale Rock, and Nacimiento) to meet the community water demand. Water is conveyed from Salinas Reservoir through 9.2 miles of 24-inch diameter reinforced concrete pipe to a three-million gallon regulating reservoir at Santa Margarita booster pump station near the northerly base of Cuesta Grade adjacent to Highway 101. The pipeline is designed to flow by gravity from the Reservoir to the regulating reservoir when the lake level is above the elevation of 1,267 feet. A booster pump station at the base of the dam, consisting of two horizontal centrifugal pumps, is capable of maintaining the rated flow of 12.4 cubic feet per second (cfs) when the water surface elevation falls below 1,267 feet. Three electrically driven horizontal centrifugal pumps at the Santa Margarita booster station pump water through 6,810 feet of 24-inch diameter reinforced concrete pipe to the entrance portal of the Cuesta Tunnel, which runs 5,327 feet through the mountains near Cuesta Grade. From the outlet portal of the tunnel, water is conveyed through an 18-inch diameter steel pipeline a distance of 5,133 feet to the City's turnout point. In 2020, 676,580 kWh of energy were used to move 1,718 acre-feet (559.96 MG) from Salinas Reservoir to the WTP. Conveyance of untreated, or “raw” water from Whale Rock Reservoir requires energy to power two pump stations. Each pump station has five-200 horsepower pumps capable of delivering water at various flow rates. The Whale Rock pipeline extends approximately 17 miles from the reservoir to the WTP. The design capacity of the pipeline is 18.94 cubic feet per second (approximately 8,500 gallons per minute). In 2020, 758,208 kWh of energy were used to move 1,305 acre-feet (425.12 MG) from Whale Rock Reservoir to the WTP. Water is conveyed from Nacimiento Reservoir through 45 miles of pipeline using three pump stations. San Luis Obispo County operates and maintains the water delivery system from Nacimiento Reservoir to participating agencies (currently the cities of Paso Robles and San Luis Obispo, Atascadero Mutual Water Company, Templeton Community Services District, County Service Area 10A [Cayucos], Santa Margarita Ranch, and Bella Vista Mobile Home Park). The City pays a proportion of the costs, equal to the volume of TABLE 22: Transfers and Exchanges Transfer Agency Transfer or Exchange Short- term or long-term Proposed Volume City of Morro Bay (emergency supply) Transfer Short-Term Not Identified San Luis Obispo County Service Area No.10 Exchange Long-Term 50 Total 50 NOTE: Water volumes are in acre-feet per year.

In 2020, 1,893,991 kWh of energy were used to move 1,958 acre-feet (637.98 MG) from Nacimiento Reservoir to the WTP. Potable Water Treatment Raw water from Salinas, Whale Rock, and Nacimiento Reservoirs is treated at the WTP via a process including ozone treatment for disinfection and oxidation, mixing and settling, filtration, chlorination, fluoridation, and THM removal using an in-tank aeration system. Energy included under that WTP also includes the Transfer Pump Station that pumps water to Reservoir 2. Potable Water Distribution The City's water distribution system utilizes pump stations to move water through over 190 miles of water mains for distribution to the community. The majority of the City’s water distribution system is fed by gravity from Reservoir 2.

Page 234 of 422 2020 Urban Water Management Plan 5-1 Chapter 5: Recycled Water This chapter was prepared to fulfill the requirements of Section 10633 (a-g) of California Water Code Division 6, Article 2, Part 2.6 regarding the City’s recycled water supply. As defined in Water Code Section 13050(n), “Recycled Water” means water which as, a result of treatment of waste, is suitable for a direct beneficial use or a controlled use that would not otherwise occur and is therefor considered a valuable resource. The City produces and distributes recycled water consistent with the regulatory requirements described below and therefore meets the minimum requirements to be classified as recycled water in this UWMP. These regulations, as set forth in Title 22, Division 4 of the California Code of Regulations, Wastewater Recycling Criteria (Title 22) and the conditions and requirements contained in the City’s National Pollutant Discharge Elimination System (NPDES) Permit Number R3-2003-081 prescribed by the Regional Water Quality Control Board (RWQCB), establish specific criteria for treatment, distribution, and application of recycled water within the state. The RWQCB and Division of Drinking Water (DDW) have a memorandum of understanding in which DDW agrees the RWQCB will be the implementing agency responsible for permitting recycled water programs. The RWQCB Master Permit for Recycled Water is the guiding document for most of the City’s requirements. In accordance with the Master Permit (WDR Order No. 03- 2003-081, October 24, 2003), the City complies with the following: 1. Meter the total quantity of reclaimed water distributed daily, 2. Monitor and record chlorine residual concentration at a point after the final chlorine contact basin, 3. Provide guidance to recycled water users including a user manual and other guidance as needed, 4. Provide instruction to all City field staff to report incidents of unauthorized daytime irrigation activity or runoff, 5. Cooperate with County Environmental Department of Health Services to ensure backflow devices are present, tested and repaired or replaced if found defective, 6. Inspect the operation of reuse sites, 7. Perform cross connection testing, 8. Conduct site supervisor training and quarterly interviews to verify system operation, and 9. Quarterly review of monthly meter readings with follow-up on change in patterns of use. The City also complies with minimum daily average discharge requirements from the Water Resource Recovery Facility (WRRF) to San Luis Obispo Creek for protection of downstream fish habitat as required by National Oceanic Atmospheric Association, National Marine Fisheries Service (NOAA NMFS). 5.1 WASTEWATER COLLECTION, TREATMENT, AND DISPOSAL The City’s wastewater collection system serves residential, commercial and industrial customers within the city limits. The City also provides service to Cal Poly State University and the County of San Luis Obispo Airport. The City’s WRRF is located on Prado Road, adjacent to U.S. 101 in the southern portion of the City. The design flow rate at the WRRF is 5.1 million gallons per day (MGD), with a 2020 average daily flow of 2.9 MGD. The WRRF discharges to San Luis Obispo Creek. An upgrade is underway at the WRRF to expand the design flow rate to 5.4 MGD. That project is scheduled to be complete in 2023. The City’s Water Reuse Project, which included improvements at the WRRF and the construction of eight miles of recycled water distribution system, was completed in October of 2006. The recycled water pump station was designed to provide up to 1,750 gallons per minute (gpm) of recycled water at a pressure of approximately 130 pounds per square inch (psi). Maximum design capacity is approximately 2.5 MGD. The distribution system was designed to serve the City through one pressure zone. Recycled water storage is provided by one-600,000 gallon underground storage tank located at the WRRF. The existing recycled water pump station was designed to accommodate future expansion with space for two additional pumps at the WRRF. The upgrade will enable the City to consider potable reuse in the future. Potable reuse is discussed more in section 5.7 of this Chapter. Page 235 of 422 2020 Urban Water Management Plan 5-2 The City’s recycled water distribution system extends to the east and west from the WRRF in the southern portion of the City. The distribution system was designed to supply irrigation water to several existing City parks, the City’s Laguna Lake Golf Course, a middle school, and future development areas. Recycled water is provided to Caltrans from a metered connection near the WRRF, which is adjacent to U.S. Highway 101. Caltrans utilizes recycled water to irrigate landscape areas along the entire highway corridor through the City, which was previously supplied with potable water. Annual usage for 2016 through 2020 is provided in Table 23. The City’s WRRF produced over 3,000 acre-feet of disinfected tertiary-treated effluent in 2020. The City is required to maintain a minimum average daily release, year-round, of treated effluent to San Luis Obispo Creek at a rate of 2.5 cubic feet per second (cfs), or approximately 1.6 mgd, to provide a flow volume adequate to support habitat for anadromous fish species within San Luis Obispo Creek. This rate totals a minimum of 1,807 acre-feet per year of creek discharge. The City monitors the release of effluent through an effluent meter at the WRRF. The balance, approximately 1,250 acre-feet in 2020, makes up the City’s available recycled water resource (See Table 24). 5.2 CURRENT RECYCLED WATER USE In 2020, recycled water was delivered to over 50 metered locations in the City for landscape irrigation. Additional sites will continue to be connected to the recycled water distribution system with new development in the City. Other notable recycled water demand figures: x Average Daily Demand in July, August, and September 2020 was over 342,000 gallons. x Peak Daily Demand was over 619,833 gallons on August 25, 2020. x Peak Monthly Demand was over 11.5 million gallons during August 2020. The City began issuing annual construction water permits in July 2009. During the 2019-20 fiscal year over 20 construction water permits were sold. Permit holders have access to an unlimited supply of recycled water for dust control and compaction on construction sites in the City. The City has metered wharf head hydrant filling stations on the recycled water distribution system, at the City’s Corporation Yard, and within the WRRF.

The 2017 Master Plan is part of a comprehensive strategy to efficiently manage the City’s water resources. The scope included the following: 1. Plan for the strategic and beneficial use of recycled water, including the potential for future potable reuse. 2. Analyze recycled water production capability in the short- and long-term, ensuring the Master Plan reflects current wastewater generation rates. 3. Understand the City’s expected growth patterns and recycled water demand. 4. Develop a hydraulic model for the recycled water distribution system that can be utilized for future infrastructure analysis. 5. Analyze the available recycled water supply, including surplus supply. 6. Confirm the long-term extent of the Master Plan area. 7. Provide a plan for incremental expansion of the recycled water distribution system. 8. Prioritize future retrofit opportunities based on defined criteria. 9. Identify future storage needs based on future peak day demand. 10. Evaluate infrastructure improvements needed to reach new customers and a prioritized Capital Improvement Project (CIP). The 2017 Master Plan covers the planning period to the year 2035 consistent with development projections in the City’s General Plan. In Table 4 of the 2017 Master Plan, the City estimated that demand existed for approximately 791 acre-feet of recycled water annually. This estimate includes serving approximately 400 AFY of recycled water for landscape irrigation to the Orcutt, Margarita, and Airport, San Luis Ranch, Avila Ranch, and Froom Ranch areas (some sites are actively using or under construction in 2021), as well as medium- and high-priority retrofits (63 AFY and 89 AFY, respectively) of existing irrigation systems to use recycled water. Projected recycled water use for 2025 through 2040 is provided in Table 23. Table 24 revisits estimates made in the 2015 UWMP for 2020 and actual 2020 recycled water deliveries.

Department of Water Resources, Table 6-5 (R). Source: City of San Luis Obispo Utilities Department, 2021. The City adopted a mandatory use ordinance for recycled water in 2004. The policy, codified in the Municipal Code as Chapter 13.24, allows the City to require the use of recycled water on parcels when considered feasible. The code language is as follows: 13.24.010 Statement of Policy When in the judgment of the city, reclaimed water service can be feasibly provided to a particular parcel for particular uses, the utilities director shall require the use of reclaimed water in lieu of potable water for those uses. As used herein, the term “feasible” means reclaimed water is available for delivery to the property in compliance with all applicable federal, state, and local laws, ordinances and regulations and such reclaimed water can be delivered to the property at an overall cost to the user which does not exceed the overall cost of potable water service (Ord. 1403 § 1,2001). For areas within the recycled water expansion area that are not subject to the mandatory use ordinance defined above, funding mechanisms or incentives may be required to achieve user site retrofits. 5.5 SEASONAL SURPLUS The City has identified a “seasonal surplus” of recycled water available in excess of required discharge to San Luis Obispo Creek (1.6129 million gallons per day or mgd as required by the National Oceanic and Atmosopheric Association, National Marine Fisheries Service in 2005) and recycled water for landscape irrigation. The primary use of recycled water in the City is for landsacpe irrigation with 73 percent of the City’s recycled water demand occuring from May through October. During 2020, 245 acre feet of recycled water was used for landscape irrigation and construction water. As only a limited amount of landscape irrigation takes place from November to April (seasonal off-peak period), more than 2 mgd of recycled water Page 238 of 422 2020 Urban Water Management Plan 5-5 is available during the seasonal off-peak period. Related to this seasonal surplus, the following goal and program was added to the General Plan, Water and Wastewater Management Element in 2010: Goal A7.1.2 Maximize the use of the City’s available recycled water supply for approved uses. Program A 7.3.4 Consider the potential to deliver available recycled water supplies to customers outside the city limits, including analysis of policy issues, technical concerns, and cost recovery, provided it is found to be consistent with the General Plan. With the update to the General Plan, Land Use Element in 2014, Policy 1.13.2 was added. This policy was broadened in 2020 to also include non-potable water: 1.13.2. Recycled Water Provision of non-potable or recycled water outside of City limits may only be considered in compliance with Water and Wastewater Element Policy A 7.3.4 and the following findings: A. Non-potable/recycled water is necessary to support continued agricultural operations. B. Provision of non-potable/recycled water will not be used to increase development potential of property being served. C. Non-potable/recycled water will not be further treated to make it potable. D. Prior to provision of non-potable/recycled water, the property to be served will record a conservation, open space, Williamson Act, or other easement instrument to maintain the area being served in agriculture and open space while non-potable/recycled water is being provided. E. Provision of non-potable and recycled water will not impair the City’s ability to maintain an adequate water supply that meets projected water demand at buildout under the General Plan including the required reliability reserve.

The upgrade will enable the City to consider either direct or indirect potable reuse in the future. Direct potable reuse is the planned introduction of recycled water either directly into a public water system (treated drinking water augmentation), as defined in Section 116275 of the Health and Safety Code, or into a raw water supply immediately upstream of a water treatment plant (raw water augmentation). Direct potable reuse is a practice which is not currently occurring in California; however, Assembly Bill (AB) 574 (Water Code, Division 7, Chapter 7.3) requires the State Water Board to adopt uniform water recycling criteria for direct potable reuse through raw water augmentation on or before December 31, 2023. Page 239 of 422 2020 Urban Water Management Plan 5-6 Additionally, the State Water Board Division of Drinking Water (DDW) published a Proposed Framework of Regulating Direct Potable Reuse in California in 2018 and updated the Framework in 2019. Indirect potable reuse occurs when tertiary or advanced treated wastewater augments drinking water resources. The two types of indirect potable reuse are: x Indirect potable reuse for groundwater recharge Ǧ where recycled water recharges a groundwater basin and groundwater is later extracted from the basin. x Reservoir water augmentation – where recycled water is added into a surface water reservoir used as a source of domestic drinking water supply. Indirect potable reuse does not actually occur until the water is subsequently pumped from the ground or withdrawn from the reservoir, treated, and added to the drinking water distribution system. Indirect potable reuse through groundwater recharge has occurred in California since 1962. Title 22, Division 4, Chapter 3, Article 5.1 (CCR §60320 et seq) describes the permitting and monitoring process required to obtain a RWQCB permit for groundwater recharge. Title 22, Division 4, Chapter 3, Article 5.3 (CCR §60320 et seq) describes the regulations governing reservoir augmentation. These regulations set requirements for the quality of treated recycled water that can be added to an augmented reservoir, the percentage of recycled water that can be added, and the required residence time before treatment at a drinking water facility. Like groundwater recharge with recycled water, reservoir water augmentation would only occur with a permit and monitoring requirements from the RWQCB. 5.7 ENERGY USE This section describes the City’s energy usage to produce and deliver recycled water to the community. Energy consumption data was acquired from PG&E for the meters associated with the recycled water process. As shown in Table 29, the process includes energy use for each of the following: x Wastewater collection conveyance, x Wastewater treatment, x Discharge and recycled water distribution. The City’s wastewater collection system includes 138 miles of gravity sewer line ranging from six -inch to 48-inch pipe. The system includes 2.4 miles of force main ranging from four- to 16-inch pipe. Wastewater generally flows by gravity to the City’s WRRF for treatment. Seven sewer lift stations (Airport, Laguna, Margarita, Prefumo, Silver City, Tank Farm) serve areas in the southern portion of the City down gradient from the WRRF. One lift station (Foothill) is located in the northern portion of the City serving approximately 70 parcels. All lift stations are monitored/controlled with a SCADA system. For 2020, influent flow is established from both metered flow and an estimation of unmetered internal recycled flow. Effluent flow is a calculation of multiple flow meters. The City’s WRRF is undergoing a comprehensive facility upgrade to address regulatory compliance and replace aging infrastructure. More accurate data will be available in the future when the upgrade is complete. The City’s recycled water pump station was designed to provide up to 1,750 gallons per minute (gpm) of recycled water at a pressure of approximately 130 pounds per square inch (psi). Maximum design capacity is approximately 2.5 MGD. The distribution system was designed to serve the City through one pressure zone. Recycled water storage is provided by one- 600,000 gallon underground storage tank located at the WRRF. The existing recycled water pump station was designed to accommodate future expansion with space for two additional pumps at the WRRF.

Page 243 of 422 2020 Urban Water Management Plan 6-1 Chapter 6: Water Supply Reliability & Drought Risk Assessment Chapter 4 discussed how the City uses multiple water sources to meet projected short- and long-term potable water demands. This chapter focuses on the reliability of those sources. This chapter also discusses the projected supplies available during a single dry water year and during multiple-dry water years to assess overall drought risk. As required by Water Code Section 10635 for the 2020 UWMP, this chapter provides an assessment of water supplies and water uses under an assumed drought period that lasts five consecutive years. Chapter 7 will discuss the water efficiency and demand management measures implemented by the City to maintain long-term water supply reliability. Actions that would be undertaken during a short-term water supply emergency, such as drought or a catastrophic supply interruption, are addressed in the City’s 2020 Water Shortage Contingency Plan (available under separate cover). 6.1 SALINAS AND WHALE ROCK RESERVOIRS For Salinas and Whale Rock Reservoirs, the City uses a computer model to simulate the combined operation of these two water supply sources over a historical period to determine the “safe annual yield” or the quantity of water which can be safely withdrawn every year without causing impacts to long- or short- term water availability, to accommodate City water demand. Salinas Reservoir and Whale Rock Reservoir are in geographically and climatologically distinct watersheds. Salinas Reservoir has a higher evaporation rate and larger watershed than Whale Rock Reservoir, but smaller storage capacity -- about 60 percent of the storage capacity of Whale Rock Reservoir. Whale Rock Reservoir has a smaller watershed, as compared to Salinas Reservoir, but greater storage capacity. Whale Rock experiences a lower evaporation rate as it is close to ocean. Coordinated operation of the two reservoirs results in maximization of safe annual yield. This approach increases the long-term water supply from these two sources when compared to operation of the two reservoirs independently. General Plan, Water and Wastewater Management Element, policy A3.3.2 states: The City will update the safe annual yield computer model for Salinas and Whale Rock Reservoirs following severe drought periods to determine if any changes are necessary to the safe annual yield amount. In 2018 to understand the impacts of climate change, the City updated to the safe annual yield model following the addition of data from the most recent drought that ended in 2016 and analysis of three independent climate change models by the U.S. Environmental Protection Agency (EPA), San Luis Obispo Council of Governments (SLOCOG)as part of the 2014 Regional Transportation Plan, and Nature Communications. The EPA climate assessment tool (Climate Resilience Evaluation and Awareness or “CREAT”) was created by the federal agency monitoring climate change. Changes identified in CREAT were derived from an evaluation of 38 global climate models recognized by the Intergovernmental Panel on Climate Change (IPCC). The SLOCOG model was recommended by City Council as it reflecteda summaryof work previously performed to examine impacts in the local area and is focused on three IPCC global climate models. The work by Nature Communications was selected as it is a preeminent peer-reviewed scientific publication. Each climate projection was applied to the City’s historical dataset for Whale Rock and Salinas reservoir’s inflow, precipitation, and evaporation. The City’s 2018 model was then used to calculate a revised safe annual yield assuming these conditions had prevailed during the historical period of record. Complete information on the analysis is LQFOXGed in the Technical Memo provided in Appendix 9. Salinas and Whale Rock Reservoirs 3 Potable Water Supplies 3 Located in Different Watersheds 3 Coordinated Operation 3 4,910 acre-feet Annually 3 Reliable during 5-Year Drought Page 244 of 422 2020 Urban Water Management Plan 6-2 On May 15, 2018, the City Council adopted Resolution 10893 amending the General Plan, Water and Wastewater Management Element to reflect a 2,030-acre-foot reduction in the safe annual yield, reducing the available volume from 6,940 acre-feet annually to 4,910 acre-feet annually from the coordinated operation of Salinas and Whale Rock Reservoirs. This reduction in safe annual yield results in a reduction of 2,030 acre-feet of water availability to the community annually. 6.2 RECYCLED WATER With a 2020 average influent flow of 2.9 million gallons per day, the City’s WRRF produces over 3,200 acre- feet of disinfected tertiary-treated effluent per year. A minimum of 1,807 acre-feet is discharged to San Luis Obispo Creek annually to provide satisfactory habitat and flow volume for fish species (steelhead trout) within the Creek environment. The balance makes up the City’s available recycled water resource which is available for approved uses. A consistent flow of wastewater to the WRRF enables the City to produce a volume of recycled water that exceeds identified seasonal demand for landscape irrigation. The distribution/delivery of recycled water is via a pump station located within the WRRF. The pump station does not have backup power during a power outage. Power outage events have been infrequent. Therefore, the City’s recycled water supply is considered a reliable water supply. Additional information on the City’s recycled water supply is provided in Chapter 5. 6.3 NACIMIENTO RESERVOIR In 2002, the San Luis Obispo County Flood Control and Water Conservation District (District) retained the services of Boyle Engineering Corporation to assess the ability of the Nacimiento Reservoir to reliably provide the District’s entitlement of 17,500 AFY to the District contractors. As part of the analysis, the study took into account the agreement with the Monterey County Water Resources Agency (MCWRA), which owns and operates the Nacimiento Reservoir facilities, that stipulates that the District entitlement through operational procedures will be “preserved” in the reservoir due to MCWRA being contractually obligated to maintain a “minimum pool” for the benefit of the District. This enables the District to maintain deliveries to the participating agencies even when reservoir levels are low, meaning that unless the water storage capacity drops below the “dead pool” of the reservoir, the District’s entitlement will always be available. The 2002 study took into account the following factors: x Short-term power outages x Delivery facility failure x Energy costs x Drought x Contamination of supply x Environmental restrictions Upon completion of the analysis relating to drought conditions, the 2002 study summarized that even though there have been several periods of drought, both short-term and long-term, the total annual entitlement for the District could be delivered consistently, even in periods of extended drought. During the worst-case drought on record in the region (2011 to 2015), Nacimiento Reservoir remained a resilient water supply capable of providing a consistent and reliable source of water for San Luis Obispo County, which includes the City’s contractual amount of 5,482 acre-feet per year. To confirm the prior analysis with more recent data, the City reviewed rainfall and inflow data from 2013 which was the driest year on record. Over that year, Nacimiento Reservoir received 35,000 acre-feet of inflow. Though this is significantly below the average inflow into the reservoir, the District’s entitlement could still be met if inflow remained at this level.

The goal of the project is to redirect water from Nacimiento Reservoir into San Antonio Lake to fill the excess capacity typically available in the lake. While the Interlake Tunnel Project has the potential to increase water storage up to 60,000 acre-feet per year in Lake San Antonio, it is unclear if the diversion from Lake Nacimiento would result in any positive or negative changes in reliability to water availability of the County’s 17,500 ace-feet per year entitlement. Lake San Antonio and Nacimiento Reservoir both discharge water to the Nacimiento River to support agriculture within the Salinas Valley, increasing storage within Lake San Antonio by diverting excess water from Nacimiento Reservoir during periods in which it was at full capacity could offer the opportunity to reduce downstream discharges from Nacimiento Reservoir during dry periods. Increased operational flexibility of the two reservoirs, if strategically implemented, could benefit all involved parties. The City will be closely monitoring the project to ensure its water rights are protected. According to the Monterey County Water Resource Agency website in 2021, the Interlake Tunnel “requires a detailed engineering analysis; but is generally planned to consist of an 11,000 foot gravity flow tunnel with an intake structure in Nacimiento Reservoir and an exit structure in San Antonio.” 6.4 GROUNDWATER Consistent with Policy A 3.2.3 from the City’s General Plan, Water and Wastewater Management Element, the City will continue to use groundwater for domestic purposes when available. As described in Chapter 4, groundwater may also be utilized by the City as a supplemental supply during a water shortage emergency. The City has utilized a number of wells in the past, with most in the southern portion of the City, especially during the drought period in the late 1980’s and early 1990’s when up to 50 percent of the City’s water demand was met utilizing groundwater. A study completed for the City in 2004 determined that up to 1,390 acre-feet of groundwater could be utilized annually. However, by the 2000 to 2009 period, the City’s ten-year average reduced to 156 acre- feet of groundwater use annually as the groundwater in the area of higher production wells was contaminated with nitrates and tetrachloroethylene (PCE). Though the City suspended using groundwater for potable purposes in April 2015, groundwater wells remain in an operable, stand-by position should the use of groundwater be needed. In July of 2020, the City received a nearly $2 million planning-phase grant, funded through Proposition 1, to study PCE contamination of the groundwater basin. A detailed understanding of the extent of PCE contamination and remediation options are necessary steps in fully utilizing the City’s groundwater pumping opportunities. The planning phase work will continue into 2022. The City is planning to apply for an implementation-phase grant to fund necessary capital improvements to put an additional groundwater well into service. This work enhances the City’s ability to extract, treat, and utilize groundwater to meet a portion of the City’s potable water demand.

The City has no known water quality constraints that would make a water source unavailable for potable water use. The City’s 2020 Annual Water Quality Report is provided in Appendix V. 6.6 WATER SUPPLY RELIABILITY ANALYSIS / DROUGHT RISK ASSESSMENT A regulatory requirement of the UWMP is to perform a water supply reliability analysis applying different worst-case drought years according to stringent guidelines set forth in the UWMP plan documentation. The following tables provide data on the reliability of the City’s water supply during normal, single-dry, and a severe drought period lasting five consecutive years. The City remains confident in the reliability of its multi- source water supply portfolio. Table 30 lists the years which correlate to the guidelines for the specific water year type and are based on rainfall information. The City’s average water year was determined to be 2020 based on review and update of the City’s average rainfall total. The City’s single dry water year was determined to be 2013 as the rainfall total that year was the lowest on record. The City’s multiple dry year scenario was determined to be 2011 to 2015 as the combined rainfall total for those five years was the lowest on record. The City makes projections of future water demand using a conservative per capita potable water use rate of 117 gpcd which is the City’s SB X7-7 target, actual water use within the community is currently 94 gpcd and not anticipated to increase beyond minor year-to-year variations over time. Table 31 summarizes the results of that analysis which, based on the City’s available water supplies and estimates of future water demand, indicates the City’s water resources are reliable during extended drought periods.

Supply total includes the City’s contractual supply to Nacimiento Reservoir, Safe Annual Yield from Salinas and Whale Rock Reservoirs, and the projected increase in recycled water deliveries. Source: City of San Luis Obispo Utilities Department, 2021. Table 32 and Table 33 summarize the City’s water supplies in a single dry year and a multiple dry year scenario. To address Water Code Section 10635 (b), Table 34 includes available water supply and demand estimate for 2021 through 2025. The water demand projections were derived using 117 gpcd and on population growth to levels identified in the City’s General Plan. Both of these factors are higher than current gpcd and the City’s current population. As the City does not project a supply shortfall due to conservative water planning, the City does not anticipate a water shortage necessitating any water supply augmentation or requiring water use restrictions. Accounting for Siltation Siltation at reservoirs is a natural occurrence that can reduce the storage capacity over long periods. The reduction of available storage reduces the safe annual yield of the reservoirs. Siltation at reservoirs varies depending on factors such as rainfall intensity and watershed management practices. Climate change could have an impact on future water availability in the form of increased siltation in reservoirs resulting from wildland fires which could affect the safe annual yield of the City’s reservoirs. Numerous studies and reports addressing siltation at Salinas Reservoir have been completed. The Whale Rock Reservoir Bathymetric Survey and Volumetric Study was completed in May 2013. The City has policies and programs in the WWME to anticipate the loss of storage at Whale Rock and Salinas Reservoirs. WWME Policy A 4.2.2 relates to Accounting for Future Siltation. The policy states: The City will account for estimated safe annual yield losses at Salinas and Whale Rock Reservoirs through 2060 by deducting 500 acre-feet of available water supplies to account for these future losses. The siltation rate will be updated as information becomes available from subsequent siltation analyses. Accounting for siltation of reservoirs contributes to the overall reliability of the City’s water supply portfolio as it ensures that the City is planning for this occurrence.

Source: City of San Luis Obispo Utilities Department, 2021 Reliability Reserve and Secondary Water Supply The City’s WWME, includes policies to maintain a “Reliability Reserve” and “Secondary Water Supply” in an effort to reduce the impacts of a water shortage on the community. The “Reliability Reserve”, identified in the City’s Charter, provides a twenty percent buffer beyond the City’s projected water demand at build out to account for future unforeseen or unpredictable long-term impacts to the City’s available water resources such as loss of yield from an existing water supply source and impacts due to climate change. The City’s Secondary Water Supply is the amount needed to meet peak water demand periods or short-term loss of City water supply sources. The City’s “Secondary Water Supply” is identified as any water supply resources above those needed to meet the Primary Water Supply and Reliability Reserve. Water and Wastewater Management Element Policies Policy A 5.2.3 Reliability Reserve. The City will establish a reliability reserve that is 20-percent of the water use rate established in Policy A 5.2.1 multiplied by the current population. The water supply designated as the reliability reserve may not be used to serve future development. Policy A 5.2.4 Secondary Water Supply. After accounting for primary water supply and a reliability reserve, any remaining water supplies shall be utilized for meeting short-term water supply shortages or peak water demands.

Page 250 of 422 2020 Urban Water Management Plan 6-8 6.7 PRECAUTIONARY POWER OUTAGES In an effort to protect communities from wildfire, Pacific Gas & Electric (PG&E) notified its municipal and private customers in 2019 of its plans to implement precautionary measures during fire season. If extreme fire danger conditions threaten a portion of the PG&E electrical system, high-risk transmission lines may be turned off, resulting in widespread power outages to San Luis Obispo County. PG&E refers to this as a Public Safety Power Shutoff (PSPS). According to PG&E, a PSPS may be necessitated by strong winds, low humidity levels, and critically dry vegetation. These outages will not be localized; and regional solutions will be limited (one city may not be able to borrow from another neighboring city needed equipment and/or resources). In the past, the City has been able to continue to provide uninterrupted water service during short-duration power outages and when limited areas of the City are affected by outages utilizing the existing storage in the water system along with limited back-up power generation. With the potential for a PSPS, the City is working to prepare for the potential for power outages lasting up to seven days or more. The City provides water service to critical facilities such as the City’s Emergency Operations Center, area hospitals, as well as the SLO County Emergency Operations Center, the Cal Poly campus, and the SLO County airport. As the driver for the PSPS is climatic conditions which could result in the higher likelihood of catastrophic fire in the County, it is imperative that the City’s water system remain operable in the event that such a fire starts. The City has four portable generators that are mobilized as needed to various locations in the City’s water conveyance system, including Pump Station A and B on the Whale Rock pipeline, and water distribution system pump stations. A permanent back-up generator is planned to be in service in 2021 at the Salinas Booster Station. A temporary back-up generator is in place at the City’s Water Treatment Plant as a permanent on-site water treatment plant generator currently being designed. Back-up power is not currently planned for the Nacimiento Water Project pump stations. However, with generators available to provide water from both Whale Rock and Salinas reservoirs, staff is confident it can maintain water service during a PSPS event. 6.8 REQUIRED UWMP STANDARDIZED TABLES: Basis of Water Year Data Year Type Base Year Available Supplies if Year Type Repeats Agency may provide volume only, percent only, or both Volume Available % of Average Supply Average Year 2020 10,143 100% Single-Dry Year 2013 10,143 100% Multiple-Dry Years 1st Year 2011 10,143 100% Multiple-Dry Years 2nd Year 2012 10,143 100% Multiple-Dry Years 3rd Year 2013 10,143 100% Multiple-Dry Years 4th Year 2014 10,143 100% Multiple-Dry Years 5th Year 2015 10,143 100% NOTES: Table 7-1(R) Normal Year Supply and Demand Comparison 2025 2030 2035 2040 Supply totals (autofill from Table 6-9) 10,337 10,537 10,587 10,637 Demand totals (autofill from Table 4-3) 7,272 7,713 8,191 8,624 Difference 3,166 2,824 2,396 2,013 NOTES: Table 7-2(R) Page 251 of 422 2020 Urban Water Management Plan 6-9 Single Dry Year Supply and Demand Comparison 2025 2030 2035 2040 Supply totals 10,337 10,537 10,587 10,637 Demand totals 7,272 7,713 8,191 8,624 Difference 3,166 2,824 2,396 2,013 NOTES: Table 7-3(R) Multiple Dry Years Supply and Demand Comparison 2025 2030 2035 2040 First year Supply totals 10,337 10,537 10,587 10,637 Demand totals 7,272 7,713 8,191 8,624 Difference 3,166 2,824 2,396 2,013 Second year Supply totals 10,337 10,537 10,587 10,637 Demand totals 7,272 7,713 8,191 8,624 Difference 3,166 2,824 2,396 2,013 Third year Supply totals 10,337 10,537 10,587 10,637 Demand totals 7,272 7,713 8,191 8,624 Difference 3,166 2,824 2,396 2,013 Fourth year Supply totals 10,337 10,537 10,587 10,637 Demand totals 7,272 7,713 8,191 8,624 Difference 3,166 2,824 2,396 2,013 Fifth year Supply totals 10,337 10,537 10,587 10,637 Demand totals 7,272 7,713 8,191 8,624 Difference 3,166 2,824 2,396 2,013 NOTES: Table 7-4(R) Page 252 of 422 2020 Urban Water Management Plan 6-10 Five Year Drought Risk Assessment 2021 Total Total Water Use 6,463 Total Supplies 10,147 Surplus/Shortfall w/o/ WSCP Action 3,684 Planned WSCP Actions (use reduction and supply augmentation) WSCP – supply augmentation benefit 0 WSCP – use reduction savings benefit 0 Revised Surplus/(shortfall) 3,684 Resulting % Use Reduction from WSCP action 0% 2022 Total Total Water Use 6,528 Total Supplies 10,157 Surplus/Shortfall w/o/ WSCP Action 3,629 Planned WSCP Actions (use reduction and supply augmentation) WSCP – supply augmentation benefit 0 WSCP – use reduction savings benefit 0 Revised Surplus/(shortfall) 3,629 Resulting % Use Reduction from WSCP action 0% 2023 Total Total Water Use 6,593 Total Supplies 10,167 Surplus/Shortfall w/o/ WSCP Action 3,574 Planned WSCP Actions (use reduction and supply augmentation) WSCP – supply augmentation benefit 0 WSCP – use reduction savings benefit 0 Revised Surplus/(shortfall) 3,574 Resulting % Use Reduction from WSCP action 0% 2024 Total Total Water Use 6,659 Total Supplies 10,177 Surplus/Shortfall w/o/ WSCP Action 3,518 Planned WSCP Actions (use reduction and supply augmentation) WSCP – supply augmentation benefit 0 WSCP – use reduction savings benefit 0 Revised Surplus/(shortfall) 3,518 Resulting % Use Reduction from WSCP action 0% 2025 Total Total Water Use 6,725 Total Supplies 10,187 Surplus/Shortfall w/o/ WSCP Action 3,462 Planned WSCP Actions (use reduction and supply augmentation) WSCP – supply augmentation benefit 0 WSCP – use reduction savings benefit 0 Revised Surplus/(shortfall) 3,462 Resulting % Use Reduction from WSCP action 0% NOTES: Table 7-5(R) Page 253 of 422 2020 Urban Water Management Plan 7-1 Chapter 7: Water Conservation & Demand Management Measures 7.1 HISTORY Water conservation is an integral part of the City’s overall water management strategy and was first referenced as a part of the water management policies in 1973. In 1985, the City adopted the Annual Water Operational Plan policy that established water conservation as a means of extending water supplies during projected water shortages. Many technological and philosophical changes have occurred since that time, proving that water conservation can be used for both a short-term corrective measure to address immediate water supply shortages, and as a long-term solution to water supply reliability. Demand management measures are those water conservation measures, programs, and incentives that prevent the waste of water and promote the reasonable and efficient use and reuse of available supplies. Brief summaries of the City’s demand management measures are provided below to provide additional detail about the City’s water conservation program. 7.2 WATER CONSERVATION PROGRAM HIGHLIGHTS (2016-2020) The Utilities Department’s Water Resources section implemented the City’s core water conservation programs from 2016 to 2020. Examples of successful program activities during this timeframe were: 1. Enforcement of all water conservation related municipal codes 2. Monthly site inspections of properties with suspected leaks and inefficient uses of water 3. Enforcement of the toilet retrofit upon sale program 4.

Enforcement of Model Water Efficient Landscape Ordinance (MWELO) Through the City’s water conservation programs and policies, water demand over the five-year period ranged from a high of 97 gpcd in 2017 to a low of 88 gpcd in 2016, as shown in Figure 5. Annual per capita water use for that period was well below the City’s SBX7-7 compliance year goal of 117 gpcd. With the continuation of the demand management measures listed above, the City anticipates ongoing compliance with state conservation mandates into the future.

On June 2, 2015, the City Council adopted resolutions declaring a local drought emergency and requiring the deferral of new landscape installation or the use of modified landscape plans during the drought emergency. On June 16, 2015, the City Council adopted a resolution further limiting outdoor irrigation of ornamental landscaping or turf with potable water to two days a week. These measures remained in place through 2016. A 2016 Executive Order (B-37-16), approved by Governor Brown on May 9, 2016, bolstered California’s drought resilience and preparedness by establishing longer-term water conservation measures that include permanent monthly water use reporting, new urban water use targets, reducing system water loss, eliminating clearly wasteful practices, and strengthening urban drought contingency plans. These measures aim to not only reduce immediate water use but to establish a long-term change in the way Californians think about water. Following abundant rainfall, on April 7, 2017 Governor Brown issued an Executive Order ending the state of emergency in California and eliminating statewide water use reduction requirements, including the City’s 12 percent water use reduction requirement. The City Council rescinded the local emergency drought declaration and restrictions on water use on June 20, 2017. This conservation measure that originated with the drought became a permanent requirement under the 2016 Executive Order Page 255 of 422 2020 Urban Water Management Plan 7-3 7.4 WATER WASTE PREVENTION ORDINANCES According to the DWR 2020 UWMP Guidebook, a water waste ordinance that explicitly states the waste of water is to be prohibited must be adopted. To promote responsible use of water and minimize water waste, the City’s water waste prohibitions are included in Chapter 13.07 of the City’s Municipal Code, which defines water waste as follow: 13.07.020 – Water runoff prohibited. A. No person shall cause any water delivered by the city water system to flow away from property owned, occupied or controlled by such person in any gutter, ditch or in any other manner over the surface of the ground, so as to constitute water waste runoff. B. “Water waste runoff” means water flowing away from property and which is caused by excessive application(s) of water beyond reasonable or practical flow rates, water volumes or duration of application. (Ord. 1089 § 1 (part), 1987) In accordance with City Municipal Code 13.07.030, when deemed necessary in the judgment of the City Council to conserve water during critical water periods, the City Council may also by resolution declare an emergency condition and do any or all of the following which in its judgment is deemed advisable after publication of notice thereof in a newspaper of general circulation distributed in the City or after reasonable notice thereof is otherwise given by the City to users: 1. Limit irrigation within the City water service area to specified hours, or prohibit irrigation entirely within the service area or any portion or portions thereof; 2. Limit all customers inside the City water service area to specified maximum usages of water for each category of users; 3. Implement other water conservation measures as deemed appropriate. 7.5 WATER METERING In accordance with the 2020 UWMP guidebook and CWC 527 (a) (1), the City has metered all of its service connections. Having all service connections metered encourages water conservation by effectively billing customers for the quantity of water consumed, forming a relationship between water consumed and total cost of the water bill. The City also continues to implement effective metering requirements for new development requiring separate water meters for residential, non-residential, and landscape uses. There are approximately 450 dedicated landscape water meters in the City, which represents approximately three percent of the total number water meters. In 2020, 8.3 percent of potable water consumption was to dedicated landscape meters. An additional 4.4 percent of total water consumption was recycled water for landscape irrigation. In the City, separate landscape water meters are required for new commercial, institutional, and multi-unit residential development projects that have greater than 1,000 square feet of landscaping. The City does not allow submeters in place of a dedicated landscape meter for landscape irrigation. As the sewer charges are based on a customer’s water usage in the City, commercial, institutional, and multi-unit residential customers often opt to install a separate water meter to avoid paying sewer charges on water used for landscape irrigation. Use of recycled water for landscape irrigation is required for customers in the City’s Recycled Water Master Plan area. Recycled water is discussed in Chapter 6. City Municipal Code Section 17.70.220 (B) Water Efficient Landscape Standards states: For the efficient use of water, a landscape shall be designed and planned for the intended function of the project. Page 256 of 422 2020 Urban Water Management Plan 7-4 The City’s water meter replacement program is implemented by the Water Distribution section of the Utilities Department. Under the program, water meters are replaced based on age of meter and as defective or under-registering meter are identified. Water meter replacement ensures accurate consumption data is provided to both the customer and the utility. The City offers a downloadable tool on its website (Microsoft Excel file) to calculate a project’s Estimated Total Water Use (ETWU) and Maximum Applied Water Allowance (MAWA). The calculator is pre- populated with the City’s reference evapotranspiration for consistency. Annually, the Utilities Department calibrates the effluent meters at the City’s Water Treatment Plant to ensure accurate accounting of the water going to the water distribution system. Additionally, the City tests approximately 1 to 2 percent of its retired water meter inventory annually for a baseline of performance of the existing metering infrastructure. The City is currently piloting a cellular based automatic metering infrastructure (AMI) system in partnership with Cal Poly. The pilot is designed to monitor all water used by Cal Poly both on campus and at offsite facilities in 15-minute increments, to better understand the impact of the University’s demand on the City’s potable water system. 7.6 WATER RATE STRUCTURE AND COST OF SERVICE According to the DWR 2020 UWMP Guidebook, retail water agencies need to describe the pricing structure that is used by the water agency. The City’s water rates were developed as part of a comprehensive cost- of-service methodology that fairly apportions costs to all customers prepared by HDR Engineering, Inc. (HDR) in 2017. HDR developed the City’s water rates based on the American Water Works Association M1 Manual methodology to meet the requirements of California constitution article XIII D, section 6, commonly referred to as Proposition 218 (Prop 218). The City’s Cost of Service Study describes customer class characteristics, identifies unit costs, and equitably allocates costs among the City’s customer classes to establish the cost-basis of the water rates. This analysis looked at water consumption, seasonal usage patterns, water meter sizes, and other factors to determine service- related cost factors. Subsequent water rate confirmation studies were completed by HDR for the City in 2019 and 2021 to support proposed rate increases. 7.7 PUBLIC EDUCATION AND OUTREACH The City has used public education and outreach as a mechanism for decreasing water use in the City and for promoting water conservation since the 1970s. The City’s public outreach and education programs currently include the following: Table 37: Water Meters (2016 to 2020) Year Total Water Meters in the City Total Water Meters Replaced 2016 15,222 236 2017 15,353 156 2018 15,430 458 2019 15,651 311 2020 15,846 907 Five-Year Average of Water Meters Replaced 414 Source: City of San Luis Obispo Utilities Department, 2021.

School education programs (K-12) 15. Meetings with local homeowners associations 16. Meetings with local business groups The City is committed to reviewing and modifying the public education and outreach program to ensure that messaging stays effective and relevant. 7.8 PROGRAMS TO ASSESS AND MANAGE DISTRIBUTION SYSTEM REAL LOSS The City has been conducting annual AWWA water loss audits since 2009. Water loss statistics identified from the AWWA water audits can be viewed in detail in Chapter 3 and Appendix IV. To continue to reduce water loss, the City conducts service line replacement projects based on service line age and condition, along with extensive programs to replace defective polybutylene service lines that have been identified to have a high likelihood of failure. Water meter replacement programs exist to replace meters based on age, consequence of failure, and likelihood of failure. Along with these maintenance programs, the City also implements a valve exercising program that ensures water mains can be isolated during repairs to minimize the amount of water lost during water main breaks and repairs. In 2015, the City completed its Potable Water Distribution System Operations Master Plan which identifies and prioritizes future maintenance and capital improvement projects which will reduce future water loss due to infrastructure failure. That work effort included development of a comprehensive hydraulic model of the City’s water distribution system. The hydraulic model is used to determine available service pressure and is maintained annually to keep it current with waterline replacement project, new water main installations, zone consolidations, etc. In 2019, the City began using acoustic correlation equipment where acoustic sensors are attached to water valves to measure the speed at which sounds waves travel along the pipe. These sensors effectively listen to water flowing through the pipe and can detect when water is escaping through a leak. The location can then be pinpointed within about two feet, which helps reduce excavation costs. Using this tool regularly the City can: x More accurately locate small leaks, resulting in less damage to surrounding infrastructure x Further optimize its capital spending Page 258 of 422 2020 Urban Water Management Plan 7-6 x Minimize water main breaks, water loss, and damage from leaks x Better manage aging water infrastructure The City will continue to work to reduce real and apparent water losses by: 9 Replacing aging infrastructure to prevent pipe breaks and leaks. 9 Implementing a comprehensive meter testing and calibration program to ensure water meters are functioning per manufacturers’ specifications. 9 Continuing with its comprehensive meter replacement strategy to ensure water used at homes and businesses is correctly recorded. 9 Performing routine billing audits to reduce data handling errors. 7.9 WATER CONSERVATION PROGRAM COORDINATION AND STAFFING SUPPORT The Water Resources section of the Utilities Department manages and implements water conservation programs for the City. This section consists of a manager who coordinates the conservation programs, two full time Water Resource Technicians, and temporary staffing as needed. Many support services such as the school education program and elements of the public outreach program are provided by professional services contract to ensure the City meets its conservation goals and promotes responsible water use. 7.10 OTHER DEMAND MANAGEMENT MEASURES For over twenty years, the City has implemented cost-effective programs to increase water efficiency citywide. The City implemented the following demand management measures and plans to continue implementing these measures into the future. The following is a description of these additional programs. Customer Water Audits The Utilities Department’s Water Resources section offers no-cost indoor and outdoor water audits to customers who have high water use or would like to reduce their water consumption. Water resource technicians examine the property with the customer to identify potential water saving opportunities and provide information about irrigation reduction methods, proper property maintenance, low flow fixtures installation, and general information on methods for reducing water use. This service is often offered proactively to customers who have unexplained high use, water waste violations, or other instances where audits could provide potential water savings. Customers can also request a water audit on the City’s website. Rebate Programs During the past drought in 2015, the City Council authorized $100,000 in support of effective rebate programs. $100 dollar rebates were provided for qualified toilet and washing machine replacements. Going forward, staff will be examining effective rebate programs to offer the community in the future. Real Water Loss Leaks in distribution system infrastructure, pipeline breaks, and water tank overflows. + Apparent Water Loss Unauthorized consumption (water theft), water metering inaccuracies, and data handling errors. = Total Water Loss Page 259 of 422 2020 Urban Water Management Plan 7-7 Retrofit Upon Sale Program The City’s Retrofit Upon Sale Program requires the replacement of high flow indoor water fixtures when a home has a change of ownership or had a major remodel. This program has been in place since the early 1990’s and, along with several other fixture replacement programs, has reduced the City’s long-term water demand by an estimated 1,500 acre-feet per year. All properties that have been certified to have low-flow fixtures are shown via a user-friendly online mapping tool at slowater.org, shown below in Figure 6. This tool also provides the City with a database that can be used to help project the effectiveness of future indoor water fixture rebate, offset, and replacement programs.

The reporting period corresponds to the Water Year (October 1 through September 30), the 12-month period for which precipitation totals are measured. The water year is designated by the calendar year in which it ends. This report covers Water Year 2016. The Report is organized as follows: I. Drought Update II. Water Policy Update III. Water Supply IV. Water Demand V. Water Resource Availability VI. Water Supply Accounting VII. Water Demand Management I. DROUGHT UPDATE The statewide drought emergency continued during the 2016 Water Year, with the drought now into its fifth year during 2016. State drought regulations that began in 2014, were expanded in 2015, and continued through the 2016 Water Year. On May 9, 2016, the Governor issued an Executive Order that directed the State Water Resources Control Board to adjust and extend its emergency water conservation regulations through the end of January 2017 in recognition of the differing water supply conditions for many communities, and to develop proposed emergency water restrictions for 2017 if the drought persists. The Governor’s latest drought-related Executive Order (B-37-16) established a new water use efficiency framework for California by aiming to “Make Conservation a California Way of Life.” Page 267 of 422 City of San Luis Obispo 2016 Water Resources Status Report 3 The 2016 Executive Order bolsters the state’s drought resilience and preparedness by establishing longer- term water conservation measures that include: x Permanent monthly water use reporting, x New urban water use targets, x Reducing system water loss, x Eliminating clearly wasteful practices, and x Strengthening urban drought contingency plans. These updated measures aim to not only reduce immediate water use but to establish a long-term change in the way Californians think about water. LOCAL RESPONSE The drought brought about unprecedented regulatory action from the State of California which required a mandatory 12 percent reduction in City water use when compared with 2013 water use. To comply with this mandate, the City Council adopted a drought response strategy in June 2015. This strategy is still in place and includes the following: x Adoption of a resolution declaring a drought emergency; x Adoption of a resolution to defer new landscape installation or the use of modified landscape plans during the drought emergency; x Adoption of an ordinance amending Chapter 13.07 of the City’s Municipal Code to include two- day-a-week and time-of-day restrictions for outdoor watering; x Approval of an incentive program for high efficiency toilets and washing machines; and x Adoption of a resolution establishing a permit fee for the use of the Corporation Yard groundwater well. The community continues to do an outstanding job in reducing water consumption in response to the regulations. The City is on target to meet State requirements, as shown in the table below, achieving an average 21 percent reduction in the 2016 Water Year over 2013 water usage. 2015 Water Year Reduction 2016 Water Year Reduction Total Water Year Reduction from 2013 Usage 16% 21% Note: The reduction represents the total water reduction achieved in the Water Year from water usage in 2013. The City’s mandatory 12 percent reduction went into effect in June 2015, so were not in place during the full 2015 Water Year. Data does not include recycled water. Source: City of San Luis Obispo, 2016. Page 268 of 422 City of San Luis Obispo 2016 Water Resources Status Report 4 The City’s enforcement strategy has relied on active enforcement of water waste prohibitions, with a focus on providing information and resources to the public in order to encourage the correction of existing violations and to encourage voluntary compliance. During Water Year 2016, City staff issued 528 formal and informal violation notifications. Of the 528 violations recorded, only 55 were repeat violations with only 12 total properties being contacted more than two times throughout the course of the year. Violations throughout the year were predominantly related to issues with irrigation systems. 281 of the violations recorded were related to water runoff from irrigation systems while another 228 violations were due to irrigating on a prohibited day or during prohibited hours. The remaining 20 violations were related to issues such as watering within 48-hours of measurable rainfall, washing a vehicle without a shutoff nozzle, and using a hose to wash down a driveway or sidewalk. Given the strong relationship between irrigation and water waste violations, most violations occur during peak irrigation season (from May through October) and become nearly non-existent during winter months. As shown in the Violations Heat Map, there are several areas of town where violations occur most frequently. Given advanced reporting and tracking efforts, efforts are focused on areas of town with high likelihood of violations. When violations occur they are geocoded and permanently recorded with information such as type of violation, customer contact method, and outcome of contact. This recording of data helps track frequency of violation and if response to violations needs to be escalated due to repeated violations.

Page 270 of 422 City of San Luis Obispo 2016 Water Resources Status Report 6 II. WATER POLICY UPDATE The City’s guiding water policy document for water resource planning is the General Plan Water and Wastewater Management Element (WWME). The WWME was updated on June 16, 2016 along with the 2015 Urban Water Management Plan. As part of the 2016 update, the City changed the factor used in water supply accounting and demand projections to use the per capita potable water use rate allowed under Senate Bill X7-7 (Water Conservation Act of 2009) of 117 gallons per capita per day (gpcd). The updated policy language reads as follows: The City will utilize the per capita water use rate allowed by SB X7-7 for projecting future potable water demand established as 117 gallons per capita per day. Prior to this update, the City used a water use rate based on a 10-year running average of gpcd. Using 117 gpcd is a more conservative approach as a 10-year average can be influenced by drought years where the City can experience a significant reduction in potable water demand. In June of 2016, the City updated its Urban Water Management Plan. This update is required by the State of California Urban Water Management Planning Act to occur every five years. The preparation of the 2015 Urban Water Management Plan (2015 Plan) was unique in that it took place during unprecedented drought conditions statewide. As part of the 2015 Plan, changes were made to the City’s Water Shortage Contingency Plan. Water shortage contingency planning allows for the City to be prepared for and respond to water shortages such as a drought or a catastrophic supply interruption such as a break in a transmission pipeline. To provide more time to respond to water shortages, a six-staged demand management response was included in the plan with a “Monitoring” stage in place at all times. The update to the Water Shortage Contingency Plan in the 2015 Urban Water Management Plan includes implementation of mandatory water conservation measures when the City’s water supplies are projected to last five years or less. This change from the prior plan’s three year or less plan allows for more time to incrementally implement water shortage response strategies. The policy language is as follows: Mandatory water conservation measures as described in the City’s Water Shortage Contingency Plan will be implemented when the City's water supplies are projected to last five years or less. III. WATER SUPPLY Per WWME Policy A2.2.1, the City uses multiple water sources to meet its water supply needs. The city has four primary water supply sources including Whale Rock Reservoir, Salinas Reservoir, Nacimiento Reservoir, and recycled water (for landscape irrigation and construction water), with groundwater serving as a fifth supplemental source. The supply per source for Water Year 2016 (October 1, 2015 to September 30, 2016) is summarized below. City of San Luis Obispo Water Supply Sources 9 Nacimiento Reservoir 9 Whale Rock Reservoir 9 Recycled Water 9 Salinas Reservoir 9 Groundwater Page 271 of 422 City of San Luis Obispo 2016 Water Resources Status Report 7 2016 City Water Supply by Source (Acre Feet) Nacimiento Reservoir Whale Rock Reservoir 2 Recycled Water Salinas Reservoir Groundwater 3 Total City Water Demand 3,834.5 685.92 201.92 8.19 0 4,730.53 81.06% 14.50% 4.27% 0.17% 0 % 100% Notes: 1. All Values are rounded. 2. Water delivered to Cal Poly State University is excluded from the City’s water demand. 3. Groundwater was not used for potable purposes during the 2016 Water Year. NACIMIENTO RESERVOIR Water deliveries to the City of San Luis Obispo from Nacimiento Reservoir began in January 2011. San Luis Obispo County operates and maintains the delivery of water from Nacimiento Reservoir to participating agencies (currently the cities of Paso Robles and San Luis Obispo, Atascadero Mutual Water Company, Templeton Community Services District, County Service Area 10A [Cayucos], Santa Margarita Ranch, and Bella Vista Mobile Home Park). The Nacimiento Project Commission provides oversight to project operations, maintenance, and the project budget. The Commission is made up of representatives from each of the four agencies’ governing boards and a County Representative who is a member of the County Board of Supervisors which also sits as the Board of Directors for the Flood Control District. In March 2016, the City Council approved the addition of 2,102 afy from Nacimiento Reservoir to the City’s secondary water supply, referred to as the “full allocation” of Nacimiento. This addition brought the City’s contractual right to Nacimiento Reservoir from 3380 afy to 5,482 afy. The City uses secondary water supplies to meet short-term water supply losses due to events such as drought, pipeline maintenance, and repair of infrastructure. With uncertainty of future climatic conditions, regulation and aging infrastructure, the additional supply of water from Nacimiento Reservoir to the City’s portfolio reduces pressure on use of water supplies in Whale Rock and Salinas reservoirs serving to extend these stored supplies during future critical water shortage periods. Nacimiento Reservoir, 2016. Photo credit: City of San Luis Obispo. Page 272 of 422 City of San Luis Obispo 2016 Water Resources Status Report 8 Since the full allocation was approved in March 2016 and the budget amendment to cover the expense associated with the additional pumping costs was approved in June, the City has significantly increased the volume of water it utilized from Nacimiento to serve the community’s water demand. During the 2016 Water Year, over 81 percent of the City’s total water demand was met by Nacimiento Reservoir. The City utilized twice as much water from Nacimiento Reservoir during the 2016 Water Year than the prior year. SALINAS & WHALE ROCK RESERVOIRS Salinas and Whale Rock Reservoirs served as the City’s primary water supplies for over 50 years. The City pays the County of San Luis Obispo Flood Control and Water Conservation District (County) to provide oversight, operations, and maintenance of the Salinas Dam and related water delivery facilities. The City provides the oversight, operations, and maintenance of the Whale Rock Reservoir for the benefit of the Whale Rock Commission, a joint powers agency made up of Cal Poly State University, California Men’s Colony, and the City. During the 2016 Water Year, the City utilized a total of 694.11 acre feet from Salinas and Whale Rock reservoirs. RECYCLED WATER For the 2016 Water Year, the City delivered 202 acre feet of recycled water, up from 168 acre feet for the 2015 Water Year. The biggest increase in recycled water use during the 2016 Water Year was construction water. Total construction water use in the 2016 Water Year was 20 acre feet, up from 10 acre feet during the 2015 water year. The City has had a Construction Water Permit Program since 2010. 5,285 5,541 5,892 4,988 4,731 2,181 1,502 1,247 1,891 3,835 - 1,000 2,000 3,000 4,000 5,000 6,000 7,000 2012 2013 2014 2015 2016 Utilization of Water Supply from Nacimiento Reservoir Total City Water Demand (in acre feet)Acre Feet utilized from Nacimiento Reservoir Page 273 of 422 City of San Luis Obispo 2016 Water Resources Status Report 9 The design phase for the City’s Water Resource Recovery Facility (WRRF) Project is underway in 2016 which is planned to maximize recycled water production. The upgrade will enable the City to consider potable reuse, part of a One Water concept, in the future. The City is currently updating to the 2004 Water Reuse Master Plan which is scheduled to be complete in 2017. The City is also reviewing the rate it charges for recycled water, which has been set at 90 percent of the City’s potable rate since the program’s inception. GROUNDWATER The City transitioned from utilizing groundwater for potable purposes with the last withdrawal occurring in April 2015. The City’s groundwater wells remain in an operable, stand- by position should the use of groundwater be required. Other existing well casings are being revitalized to provide greater drought resiliency. The City is also working with a hydrogeologist to site a future well field for a potential groundwater program expansion and for siting of the withdrawal of highly treated wastewater for an indirect potable reuse system. With the emergency drought declaration in 2015, the City established a permit fee and procedures for use of the Corporation Yard groundwater well. The program was started in recognition of the drought and the importance of the groundwater resources and the management of this resource to community and others within the San Luis Groundwater Basin. During the 2016 water year, that permit program entered its second year and has 40 participants. Non-potable well water is also used at the Laguna Lake Golf Course for landscape irrigation. WATER MODELING The City performs water planning through the use of different models. The Water Projection Model, or Wet Water Model, is used to inform the amount of water the City has available during the water year. This model inputs include an annual one percent population increases, current total water demand (in gallons per capita per day), current levels of Salinas and Whale Rock Reservoir, contractual water received from Nacimiento Reservoir, and climate data associated with each reservoir in terms of lack of precipitation and increase in evaporation for the worst years of the drought (2012-14). These drought-year climate impacts are assumed for every year moving forward, even in more “normal” years such as 2015 and 2016. With this model, the City is able to analyze the effects of more severe climatic conditions, such as increased evaporation and decreased precipitation, in our stored water reservoirs. The upgrade of the Water Resource Recovery Facility will enable the City to consider potable reuse in the future, part of a One Water concept. Page 274 of 422 City of San Luis Obispo 2016 Water Resources Status Report 10 In March 2016, the model was updated to include the additional water supply from the full allocation of Nacimiento Reservoir. While the last model run shows the City having more than five years of available water, the uncertainty of when the drought will end and what impact future climate change may have still remain. IV. WATER DEMAND During Water Year 2016, over 63 percent of total water use in the City was to support single and multi-family residential uses. Historical water use is summarized below, as well as corresponding population, per capita use rate, and precipitation. The 2016 per capita water use was 91.6 gallons per capita per day (gpcd). Based on WWME policies, the City uses 117 gpcd to project water required to serve build- out population.

WATER SUPPLY ACCOUNTING Per WWME Section 5, the City accounts for water supplies necessary to meet three specific community needs: x Primary water supply x Reliability reserve x Secondary water supply The City’s primary water supply is defined as the amount of water needed to serve the build-out population identified in the General Plan, Land Use Element (2014). Table 3 in the Land Use Element identifies an urban reserve capacity of 57,200 people. The quantity of water needed for the primary water supply is calculated per WWME Policy A 5.2.2, using 117 gallons per capita per day (gpcd). The reliability reserve provides a buffer for future unforeseen or unpredictable long-term impacts to the City’s water supply. The quantity of water for the reliability reserve is established using 20 percent of the existing City population (46,117, 2016 population) at 117 gpcd, thus the reliability reserve will increase over time as population increases. The reliability reserve concept is included in the City’s Charter (Section 909) which identifies that the water may not be used to serve future development, and is defined per WWME Policy A 5.2.3. The secondary water supply is the amount of water remaining from the City’s available water resources above those needed to meet the primary water supply and reliability reserve. The secondary supply is identified to meet peak water demand periods or short-term loss of City water supply sources, per WWME Policy A 5.2.4. Water supply accounting is summarized in the table below . 2016 Water Supply Accounting (acre feet) Total Primary Water Supply Reliability Reserve Secondary Water Supply 12,109 7,496 1,499 3,114 Primary Water Supply = 117 gpcd x City Build-out Population = 117 gpcd x 57,200 x 365 day/year x Acre-Ft/325,853 gal 7,496 Acre-Ft/year Reliability Reserve = 117 gpcd x 2015 City Population x 20% = 117 gpcd x 46,117 x 365 day/year x Acre-Ft/325,853 gal x 20% 1,499 Acre-Ft/year Secondary Water Supply = Current Annual Availability – Primary Water Supply – Reliability Reserve = 12,109 Acre-Ft/year A – 7,496 Acre- Ft/year – 1,499 Acre-Ft/year 3,114 Acre-Ft/year A 2016 Annual Availability Page 277 of 422 City of San Luis Obispo 2016 Water Resources Status Report 13 VII. WATER DEMAND MANAGEMENT The City’s water conservation program is an integral part of its overall water management strategy. In the late 1980’s, the City implemented effective water efficiency programs and policies that allowed for continued community growth and economic development during water- constrained periods. Through strong conservation efforts, the community has reduced its annual average per capita water use from over 180 gallons in 1987 to 91.6 for the 2016 Water Year. With the lack of local drought relief from El Nino, the City continued its message related to water conservation while much of the media was declaring the drought “over” due to high quantities of rainfall in the northern half of the state. Along with its continued face-to-face contact with customers, the City continued to implement water conservation rebate programs, school education programs, and increased public outreach related to the ongoing drought. The outreach program currently consists of messaging on the City’s social media platforms and website along with traditional printed media such as the quarterly Resource Newsletter. In order to reach all local demographics, City staff diversified outreach efforts by attending local events such as Farmers Market, the SLO Home Expo, the Disaster Preparedness Expo, and the Community Water Forum. Adding to traditional media outlets, staff was interviewed on local radio, advertised on broadcast media, and created a video explaining the history of the City’s water resource and conservation programs. Page 278 of 422 City of San Luis Obispo 2016 Water Resources Status Report 14 REGIONAL WATER RESOURCE PLANNING Beyond the involvement in the Nacimiento Water Project, the City continues to participate as a member of the Water Resources Advisory Council and Regional Water Management Group, which promotes collaborative, integrated management of water resources within San Luis Obispo County and provides policy recommendations to the County Board of Supervisors. In addition, the City participates in the regional water conservation group Partners in Water Conservation. The Sustainable Groundwater Management Act (SGMA) is a statewide policy that empowers local agencies to adopt groundwater management plans that relate to the needs and resources of their communities. In the future, the City sees groundwater continuing to play an important and useful role in the balancing of its overall water supply portfolio. Associated with SGMA is the requirement to form a Groundwater Sustainability Agency by mid-2017 and create a Groundwater Sustainability Plan by 2022.

The reporting period corresponds to the Water Year (October 1 through September 30), the 12-month period for which precipitation totals are measured designated by the calendar year in which it ends. This report for Water Year 2017 is organized as follows: I. Drought Declaration Rescinded and Water Policy Update II. Water Supply III. Water Demand IV. Water Resource Availability V. Water Supply Accounting VI. Water Demand Management I. DROUGHT DECLARATION RESCINDED AND WATER POLICY UPDATE Following abundant rainfall this past winter, on April 7, 2017 Governor Brown issued Executive Order B- 40-17 ending the drought state of emergency in California and e liminating the City’s mandated 12 percent water use reduction. The City Council adopted resolutions to rescind the drought emergency locally on June 20, 2017. A 2016 Executive Order (B-37-16), approved by Governor Brown on May 9, 2016, bolsters California’s drought resilience and preparedness by establishing longer-term water conservation measures that include permanent monthly water use reporting, new urban water use targets, reducing system water loss, eliminating clearly wasteful practices, and strengthening urban drought contingency plans. These measures aim to not only reduce immediate water use but to establish a long-term change in the way Californians think about water. What a Difference a Year Makes – For California and San Luis Obispo The California Department of Water Resources Water Year 2017 report, subtitled “What a Difference a Year Makes,” noted that the water year “dramatically illustrated the variability in California’s annual precipitation, ending the state’s 5-year drought and coming in at second place for statewide runoff, behind the wettest year of 1983.” On the hydrologic impacts of a wet 2017, the statewide report states: Many of the hydrologic impacts of California’s prior five-year drought were remedied by the wet conditions. For the first time since 2011, runoff in major river basins exceeded 150 percent of average, in some cases exceeding 200 percent of average. The abundant runoff replenished depleted soil moisture. Depleted surface water storage in most of the state’s major reservoirs was refilled (excepting Lake Oroville, due to emergency repairs and reconstruction of its spillways). Locally, the City saw its surface water reservoirs recover between January and June of 2017. Since the end of the drought the City has seen a slight increase in overall consumption from 2016 to 2017, from 92 gallons per capita day (gpcd) in Water Year 2016 to 95 gpcd in Water Year 2017. For potable water only, the increase was from 88 gpcd in Water Year 2016 to 91 gpcd in Water Year 2017. This conservation measure that originated with the drought became a permanent requirement under the 2016 Executive Order Page 281 of 422 City of San Luis Obispo 2017 Water Resources Status Report Page 3 Water Resiliency Planning The City declared Climate Action a top priority during its January 2017 major city goal-setting workshop and identified objectives focused on energy efficiency and greenhouse gas reductions within City facilities, such as the City’s Water Treatment Plant. The City is in the study phase of an energy efficiency project at the Water Treatment Plant to utilize photovoltaic panels and install a hydropower turbine that would convert the energy in the high-pressure water line from Nacimiento Reservoir into electricity. The electricity generated on-site would offset the Water Treatment Plant’s overall power demand. Concurrently, the energy efficiency project will assess several projects identified in the adopted 2015 Potable Water Master Plan such as: pump efficiencies within plant, the primary disinfection system, water quality in storage tanks, distribution main inter-ties between service zones, and settings of related controls needed for control system (SCADA-Supervisory Control and Data Acquisition) integration. The assessment will make recommendations to replace aging infrastructure in a holistic manner from the surface water source, to the treatment plant, and within the distribution system. Although it is not clear exactly how San Luis Obispo and its watersheds will be affected, climate change will impact future water supplies. To ensure water supply resiliency under worse-case scenarios, the City utilizes a multi-source water supply discussed further in this report, makes conservative water demand projections, and continues to pursue increased water use efficiency, increased water recycling, and groundwater recharge.

Despite efforts to minimize water loss, according to the US Environmental Protection Agency, the average water system sees a difference of about 15 percent between water produced and water sold each year. The City is working to reduce both real and apparent water losses. Senate Bill 555, approved by Governor Brown in October 2015, requires retail water suppliers in California with 3,000 or more connections, or an annual water demand of over 3,000 acre-feet, to conduct an annual audit of their distribution system to quantify water loss. The standardized audit must be validated by a certified third party to ensure data accuracy and consistency in reporting. The City submitted its first annual water loss audit to the Department of Water Resources in October 2017 Calendar Year 2016 Water Loss Apparent Losses 102.8 AF Real Losses 412.9 AF Water Losses 515.7 AF Non-revenue water as percent by volume of water supplied 11.7% Non-revenue water as percent by cost of operating system 2.8% By “benchmarking” this data and setting water loss efficiency goals, the City will continue to work to reduce real and apparent water losses by: 9 Installing a computer system to monitor water system data such as pressure, flow, and tank levels for early detection of abnormalities in the water distribution system. 9 Replacing aging infrastructure to prevent pipe breaks and leaks. 9 Implementing a comprehensive meter testing and calibration program to ensure water meters are functioning per manufacturers’ specifications. 9 Implementing a comprehensive meter replacement strategy to ensure water used at homes and businesses is correctly recorded. 9 Performing routine billing audits to reduce data handling errors. Sustainable Groundwater Management Act and Formation of a Groundwater Sustainability Agency The Sustainable Groundwater Management Act (SGMA) is a statewide law that empowers local agencies to adopt groundwater management plans that relate to the needs and resources of their communities. Although currently banking its groundwater resources, the City envisions groundwater playing an important role in ensuring continued resiliency in its water supply portfolio. During the 2017 Water Year, the City became a Groundwater Sustainability Agency over the area of the San Luis Obispo Valley Groundwater Basin that lies beneath and within its jurisdictional boundaries. The San Luis Obispo Valley Groundwater Basin “eligible entities” (City, County, Golden State Water Company, Edna Ranch Mutual Water Company-East, Varian Ranch Mutual Water Company, and Edna Valley Growers Mutual Water Company) are all working collaboratively to comply with SGMA requirements for the entire Real Water Loss Leaks in distribution system infrastructure, pipeline breaks, and water tank overflows. + Apparent Water Loss Unauthorized consumption (water theft), water metering inaccuracies, and data handling errors. = Total Water Loss Page 283 of 422 City of San Luis Obispo 2017 Water Resources Status Report Page 5 groundwater basin. The GSA structure includes a Groundwater Sustainability Commission which is an advisory body to the City Council and the Board of Supervisors. The Commission consists of one member from the City Council, one County Supervisor and a representative of each of the identified water companies. The City, County, and eligible entities are required by SGMA to work together to create Groundwater Sustainability Plans by January 31, 2022. II. WATER SUPPLY Per the General Plan Water and Wastewater Management Element, Policy A2.2.1, the City uses multiple water sources to meet its water supply needs. The City has four primary water supply sources including Whale Rock Reservoir, Salinas Reservoir, Nacimiento Reservoir, and supplies recycled water for landscape irrigation and construction water. Groundwater serves as a fifth supplemental source. The supply per source for Water Year 2017 (October 1, 2016 to September 30, 2017) is summarized below. 2017 City Water Supply by Source (Acre Feet) Nacimiento Reservoir Whale Rock Reservoir 2 Recycled Water Salinas Reservoir Groundwater 3 Total City Water Demand 3,383 1,150 229 213 0 4,975 68% 23% 5% 4% 0 % 100% Notes: 1. All values are rounded. 2. Water delivered to Cal Poly State University is excluded from the City’s water demand. 3. Groundwater was not used for potable purposes during the 2017 Water Year. NACIMIENTO RESERVOIR Water deliveries to the City from Nacimiento Reservoir began in January 2011. During the 2017 Water Year, 68 percent of the City’s total water demand was met by Nacimiento Reservoir. San Luis Obispo County operates and maintains the water delivery system from Nacimiento Reservoir to participating agencies (currently the cities of Paso Robles and San Luis Obispo, Atascadero Mutual Water Company, Templeton Community Services District, County Service Area 10A [Cayucos], Santa Margarita Ranch, and Bella Vista Mobile Home Park). The Nacimiento Project Commission provides oversight to project operations, maintenance, and the project budget. The Commission is made up of representatives from each of the four agencies’ governing boards and a County Representative who is a member of the County Board of Supervisors which also sits as the Board of Directors for the Flood Control District. Since 2010, San Luis Obispo County Flood Control District, the Nacimiento Regional Water Management Advisory Committee, Monterey County Parks, and Monterey County Water Resources Agency have worked together to plan, advise, and organize a Mussel Prevention Program at Lake Nacimiento. On July 29, 2017, an inspector noticed hundreds of invasive mussels attached to a boat and prevented the owner from launching at the Heritage Ranch boat ramp.

Invasive mussels have not been found in any local San Luis Obispo County lakes to-date, due in part to inspection program efforts, along with responsible boat owners’ prevention efforts. SALINAS & WHALE ROCK RESERVOIRS Prior to receiving water from Nacimiento Reservoir, Salinas and Whale Rock Reservoirs served as the City’s primary water supplies for over 50 years. The City pays the County of San Luis Obispo Flood Control and Water Conservation District (County) to provide oversight, operations, and maintenance of the Salinas Reservoir and related water delivery facilities. The City provides the oversight, operations, and maintenance of the Whale Rock Reservoir for the benefit of the Whale Rock Commission, a joint powers agency made up of Cal Poly State University, California Men’s Colony, and the City. During the 2017 Water Year, the City utilized 1,373-acre feet from Salinas and Whale Rock reservoirs, meeting 27 percent of total City water demand. Safe Annual Yield Update Safe annual yield analyses of available water supply sources are based on rainfall, evaporation, and stream flow experienced during a historical period. Although future conditions are unlikely to occur in the precise sequence and magnitudes as have occurred historically, this technique provides a conservative estimate of the future water supply capability of the existing sources, and provides a tool for observing the impacts of increased temperature, evaporation, and decreased precipitation. In 1988, the City contracted with engineering firm Leedshill-Herkenhoff, Inc., to prepare a detailed analysis of the coordinated operation of Salinas and Whale Rock Reservoirs and create a model to determine the safe annual yield. The report was completed in 1989 and utilized data from 1943 through 1991 including drought periods in 1946-51, 1959-61, and 1976-77. Key assumptions used in the model were that the "controlling drought period" was from 1946 to 1951, that the City only used Whale Rock Reservoir when Salinas Reservoir was below minimum pool or could not meet the City’s monthly demand, and that minimum pool at Salinas and Whale Rock of 400 and 500 acre-feet, respectively. The minimum pool at each lake is the amount of water that must be left in the lake for fishery and habitat resources (in 2017, minimum pool for each lake is 2,000-acre feet). Under those assumptions, the study estimated the City’s total safe annual yield from the two reservoirs to be 9,080 acre-feet per year. In 1991, staff updated the safe annual yield model to examine the impact of the 1986-91 drought and revise the assumptions on the amount of water used from Whale Rock Reservoir each year to more accurately reflect the way the City used that resource. The analysis determined that the 1986-91 drought was the critical drought of record for the two reservoirs. When siltation is included, these revised assumptions resulted in a reduction in the safe annual yield estimate to the 6,940-acre feet recognized today. The most recent drought data is currently being analyzed and peer-reviewed to determine if reductions to the City’s current safe annual yield will be necessary going forward. Reductions are anticipated as the recent drought is now the critical drought of record. Revisiting the safe annual yield model will also Whale Rock Reservoir Level Gauge. Page 285 of 422 City of San Luis Obispo 2017 Water Resources Status Report Page 7 consider revision to the assumptions on the amount of water used from Salinas and Whale Rock Reservoirs each year to accurately reflect the way the City uses its available water resources. Spillway Assessment As a result of the spillway failure at Oroville Dam, the Department of Water Resources (DWR) is requiring detailed analyses of dams that have large spillways at high hazard dams. Though there are no known deficiencies in the Whale Rock spillway, in May 2017, the City received a letter from the DWR requesting preparation of a work plan for a comprehensive spillway condition assessment by August 1, 2017. By conducting an analysis of design, current conditions, and underlying or adjacent geology, any deficiencies in the spillway will be identified. If required, corrective action will be planned and projects implemented to ensure the ability of Whale Rock Reservoir’s spillway to function as designed. The Work Plan for Whale Rock Reservoir’s Comprehensive Spillway Condition Assessment was approved in September. The intent of the assessment is to evaluate the ability of the spillway to function as intended during normal operations as well as during a flood event. The tasks listed in the work plan include: x Review of the spillway’s design features using available as-built drawings, design and construction records x Evaluation of the existing conditions of the spillway x Geologic inspection x Evaluation of all inspection and repair records The City’s Utilities Department staff is developing a scope of work for the comprehensive spillway analysis based on the approved Work Plan. The scope of work will be the basis for a request for proposals to identify qualified consultants to perform the spillway analysis. Pipeline Reliability Analysis The 18-mile long Whale Rock pipeline was constructed in the late 1950s and has served the City well since 1960, requiring minimal maintenance and repairs. A pipeline reliability analysis was prioritized as part of the Whale Rock Reservoir capital improvement program for 2017-19. The analysis is expected to be completed during the 2018 Water Year. By determining the true condition of the pipeline utilizing modern technology, it is expected the Commission will be able to focus resources on needed point repairs to the pipeline and avoid full- scale replacement based on pipe age. Whale Rock Reservoir Spillway 30-inch Whale Rock Pipeline Repair Conducted in June 2017 Page 286 of 422 City of San Luis Obispo 2017 Water Resources Status Report Page 8 RECYCLED WATER For the 2017 Water Year, the City delivered 229-acre feet of recycled water, up from 202-acre feet for the 2016 Water Year. The City Council adopted a resolution approving the 2017 Recycled Water Master Plan on March 21, 2017 and authorized staff to negotiate an agreement for delivery of recycled water outside the city limits consistent with policies and findings identified in the City’s General Plan. The design phase for the City’s Water Resource Recovery Facility (WRRF) Project continued through Water Year 2017. Construction is planned to begin in October 2018 and continue through 2021. When complete, the WRRF Project will maximize recycled water production. The project will also enable the City to consider potable reuse, part of a One Water concept, in the future. As part of a larger property upgrade, the Irish Hills Hamlet, a 146-unit apartment complex on Los Osos Valley Road originally constructed in the 1970s, retrofitted its landscape and irrigation system to utilize recycled water. The property has almost 76,000 square feet of landscaped area and is estimated to offset five-acre feet of potable water use with the retrofit. GROUNDWATER The City stopped using groundwater for potable purposes in April 2015. The City’s groundwater wells remain in an operable, stand-by position should the use of groundwater be required. During the 2017 Water Year, the City continued its work with a hydrogeologist to site a future well field for a potential groundwater program expansion. III. WATER DEMAND During Water Year 2017, 67 percent of total water use in the City was to support single and multi-family residential uses, 25 percent was to support commercial and other non-residential development, and eight percent was to support landscape irrigation (separately metered). Historical water use is summarized below, as well as corresponding population, per capita use rate, and precipitation. The 2017 per capita water use was 95 gallons per capita per day (gpcd). Based on the City’s General Plan Water and Wastewater Management Element policies, the City uses 117 gpcd to project water required to serve build-out population. Irish Hills Hamlet became the City’s latest recycled water customer in August 2017 Page 287 of 422 City of San Luis Obispo 2017 Water Resources Status Report Page 9 Population, Water Use & Rainfall Year Population Total Water Use (acre feet) Per Capita Water Use (gpcd) Rainfall1,2,3 (inches) 2008 44,579 6,359 127 18.1 2009 44,829 6,134 122 18.9 2010 44,948 5,489 109 36.0 2011 45,418 5,285 104 18.9 2012 45,308 5,541 109 21.5 2013 45,541 5,892 116 3.8 2014 45,473 5,524 109 14.2 2015 45,802 4,990 97 11.8 2016 46,117 4,731 92 17.8 2017 46,724 4 4,975 95 35.1 Notes: 1.

WATER SUPPLY ACCOUNTING Per General Plan Water and Wastewater Management Element, Section 5, the City accounts for water supplies necessary to meet three specific community needs: x Primary water supply x Reliability reserve x Secondary water supply The City’s primary water supply is defined as the amount of water needed to serve the build-out population identified in the General Plan, Land Use Element (2014). Table 3 in the Land Use Element identifies an urban reserve capacity of 57,200 people. The quantity of water needed for the primary water supply is calculated per WWME Policy A 5.2.2, using 117 gallons per capita per day (gpcd). The reliability reserve provides a buffer for future unforeseen or unpredictable long-term impacts to the City’s water supply. The quantity of water for the reliability reserve is established using 20 percent of the existing City population (46,724, 2017 population) at 117 gpcd, thus the reliability reserve will increase over time as population increases. The reliability reserve concept is included in the Primary Water Supply = 117 gpcd x City Build-out Population = 117 gpcd x 57,200 x 365 day/year x Acre-Ft/325,851 gal 7,496 Acre-Ft/year Reliability Reserve = 117 gpcd x City Population x 20% = 117 gpcd x 46,724 x 365 day/year x Acre-Ft/325,851 gal x 20% 1,225 Acre-Ft/year Secondary Water Supply = Current Annual Availability – Primary Water Supply – Reliability Reserve = 12,115 Acre-Ft/year A – 7,496 Acre- Ft/year – 1,225 Acre-Ft/year 3,394 Acre-Ft/year A 2017 Annual Availability Page 289 of 422 City of San Luis Obispo 2017 Water Resources Status Report Page 11 City’s Charter (Section 909) which identifies that the water may not be used to serve future development, and is defined per WWME Policy A 5.2.3. The City’s secondary water supply is the amount of water remaining from available water resources above those needed to meet the primary water supply and reliability reserve. The secondary supply is identified to meet peak water demand periods or short-term loss of City water supply sources, per General Plan Water and Wastewater Management Element, Policy A 5.2.4. Water supply accounting is summarized in the table below. 2017 Water Supply Accounting (acre feet) Total Primary Water Supply Reliability Reserve Secondary Water Supply 12,115 7,496 1,225 3,394 VI. WATER DEMAND MANAGEMENT The water conservation program is an integral part of the City’s overall water management strategy. In the late 1980’s, the City implemented effective water efficiency programs and policies that allowed for continued community growth and economic development during water-constrained periods. It is estimated that 90 percent of residential toilets in the City have been retrofitted to 1.6 gallons per flush or more efficient. The City’s Toilet Retrofit Program is still active, requiring replacement of inefficient toilets upon change of ownership of a home. Through strong conservation efforts, the community has reduced its annual average per capita water use from over 180 gallons in 1987 to 95 for the 2017 Water Year. To reach all local demographics, outreach efforts were expanded by attending local events such as Farmers Market, Earth Day, and the Disaster Preparedness Expo. Conservation messaging also continued through traditional media sources as well as new avenues such as on-line “How To” videos available at the City’s website (slowater.org) explaining common areas around the house where leaks occur and unnecessarily consume water. During the 2017 Water Year, the City’s Water Efficient Landscape Ordinance was updated with new climate data which reduced the acceptable amount of irrigation demand at newly constructed and landscaped properties. REGIONAL WATER RESOURCE PLANNING The City continues to participate as a member of the Water Resources Advisory Committee and Regional Water Management Group, which promotes collaborative, integrated management of water resources within San Luis Obispo County and provides policy recommendations to the County Board of Supervisors. In addition, the City participates in the regional Partners in Water Conservation group which is made up of water conservation professionals from local agencies. The group meets every other month to discuss trends in the industry, upcoming changes to regulations, and to work together on regional messaging related to water conservation and water use efficiency.

The reporting period corresponds to the Water Year (October 1, 2017 through September 30, 2018), the 12-month period for which precipitation totals are measured designated by the calendar year in which it ends. This report for Water Year 2018 is organized as follows: I. Water Projects and Policy Update II. Water Supply III. Water Demand IV. Water Resource Availability V. Water Supply Accounting I. WATER PROJECTS AND POLICY UPDATE 2018 Update to General Plan, Water and Wastewater Management Element In May 2018, the City Council approved text amendments to the City’s Water and Wastewater Management Element (WWME) of the General Plan. The primary focus of the amendment was to provide updated water supply information from the City’s safe annual yield model. No policy changes were made as part of the amendment. The City defines the terminology “safe annual yield” as the amount of water which can be reliably withdrawn annually from coordinated operation of Salinas and Whale Rock Reservoirs. A previous key assumption used in the model was the "controlling drought period" from 1986-1991. The 2018 update to the safe annual yield model added data from the most recent drought that ended in 2016 consistent with WWME program A 3.3.2 and analyzed three climate change scenarios. Based on the updated modeling and analysis of climate change scenarios, safe annual yield from Salinas and Whale Rock Reservoirs was reduced from 6,940-acre feet to 4,910-acre feet as part of the amendment. Change in Annual Water Supply Availability 2017 Annual Availability 2018 Annual Availability Salinas Reservoir and Whale Rock Reservoir 6,940 AF 4,910 AF1 Nacimiento Reservoir 5,482 AF 5,482 AF Recycled Water 193 AF 238 AF Siltation to 2060 (500 AF) (500 AF) TOTAL 12,115 AF 10,130 AF NOTES: 1. Reflects reduction in Safe Annual Yield as determined by the City’s model. 2. Water supply accounting data is in “AF” or acre feet. Although this is a significant reduction in the safe annual yield from these reservoirs, the City has a multi- source water supply to meet the City’s future water demand. Data provided in Section IV of this report on Water Resource Availability, reflects the updated WWME. Page 292 of 422 City of San Luis Obispo 2018 Water Resources Status Report Page 3 Water Resiliency Planning – Water Energy Efficiency Project The City declared Climate Action a Major City Goal in the 2017-19 Financial Plan and identified objectives focused on energy efficiency and greenhouse gas reductions within City facilities, such as the City’s Water Treatment Plant. In April, the City Council approved Resolution 10878 authorizing participation in Pacific Gas and Electric’s Sustainable Solutions Turnkey Program for the Water Energy Efficiency Project. The Project is analyzing both the use of photovoltaic panels and a hydropower turbine that would convert the energy in the high-pressure water line from Nacimiento Reservoir into electricity. The electricity generated would offset the Water Treatment Plant’s overall power demand (Water = Energy). The Project is also assessing pump efficiencies within the Water Treatment Plant, the primary disinfection system, water quality in storage tanks, water distribution main inter-ties between service zones, and settings of related controls needed for control system (SCADA-Supervisory Control and Data Acquisition) integration. Recommendations will be presented to the City Council in 2019 on alternative energy generation opportunities as well as replacing aging infrastructure in a holistic manner from the surface water source, to the treatment plant, and within the distribution system. Water = Energy Water Energy Efficiency Project, 2018. Page 293 of 422 City of San Luis Obispo 2018 Water Resources Status Report Page 4 2018 State Legislation on Water Conservation and Drought Planning The California State Legislature (Legislature) enacted two policy bills in 2018 – Senate Bill (SB) 606 and Assembly Bill (AB) 1668 – to establish a new foundation for long- term improvements in water conservation and drought planning to adapt to climate change and the resulting longer and more intense droughts in California. These two bills amend existing law to provide expanded and new authorities and requirements to enable permanent changes and actions for those purposes, improving the state's water future for generations to come. In August 2018, the State made the Public Review Draft of Making Water Conservation a California Way of Life available addressing the four primary goals in Executive Order B-37-16 and the 2017 Framework: (1) use water more wisely, (2) eliminate water waste, (3) strengthen local drought resilience, and (4) improve agricultural water use efficiency and drought planning. Goals 1 through 3 will apply to the City’s water planning. The bills include changes in Urban Water Management Plan (UWMP) preparation requirements as well as schedule and content provisions for the most critical reporting requirement – the annual water use report. Under the new authorities and requirements, the City would be required to prepare, adopt, and submit a Water Shortage Contingency Plan (WSCP) and conduct a Drought Risk Assessment (DRA) every five years in addition to conducting an annual water supply and demand assessment. The City already has adopted a WSCP and prepares this WRSR annually. However, these documents will need to align with new State requirements with the 2020 update to the City’s UWMP.

WATER SUPPLY Per the General Plan Water and Wastewater Management Element, Policy A2.2.1, the City uses multiple water sources to meet its water supply needs. The City has four primary water supply sources including Whale Rock Reservoir, Salinas Reservoir, Nacimiento Reservoir, and supplies recycled water for landscape irrigation and construction water. Groundwater serves as a fifth supplemental source. The supply per source for Water Year 2018 (from October 1, 2017 to September 30, 2018) is summarized below. 2018 City Water Supply by Source (Acre Feet) Nacimiento Reservoir Whale Rock Reservoir 2 Recycled Water Salinas Reservoir Groundwater 3 Total City Water Demand 3,848 410 244 723 0 5,225 73% 8% 5% 14% 0% 100% Notes: 1. Values are rounded. 2. Water delivered to Cal Poly State University is excluded from the City’s water demand. 3. Groundwater was not used for potable purposes during Water Year 2018. During Water Year 2018, 73 percent of the City’s total water demand was met by Nacimiento Reservoir. San Luis Obispo County operates and maintains the water delivery system from Nacimiento Reservoir to participating agencies (currently the cities of Paso Robles and San Luis Obispo, Atascadero Mutual Water Company, Templeton Community Services District, County Service Area 10A [Cayucos], Santa Margarita Ranch, and Bella Vista Mobile Home Park). The Nacimiento Project Commission provides oversight to project operations, maintenance, and the project budget. The Commission is made up of representatives from each of the four agencies’ governing boards and a County Representative who is a member of the County Board of Supervisors which also sits as the Board of Directors for the Flood Control District. During Water Year 2018, the City utilized a total of 1,133-acre feet from Salinas and Whale Rock reservoirs, meeting 22 percent of total City water demand. The City pays the County of San Luis Obispo Flood Control and Water Conservation District (County) to provide oversight, operations, and maintenance of the Salinas Reservoir and related water delivery facilities. The City provides the oversight, operations, and maintenance of the Whale Rock Reservoir for the benefit of the Whale Rock Commission, a joint powers agency made up of Cal Poly State University, California Men’s Colony, and the City. For Water Year 2018, the City delivered 244-acre feet of recycled water for landscape irrigation and construction water, up from 229-acre feet in Water Year 2017 and five percent of total City water demand. New recycled water customers include the Homeless Services Center located on Prado Road and the new Park and Ride located on Calle Joaquin. Construction water use increased from 19-acre feet in Water Year 2017 to 36-acre feet in Water Year 2018. The design phase for the City’s Water Resource Recovery Facility (WRRF) Project continued through Water Year 2018. Construction of the Project is planned to begin in 2019 and will take approximately three years. When complete, the new technology used at the WRRF will reduce overall treatment time from approximately 28 hours to eight hours.

Page 295 of 422 City of San Luis Obispo 2018 Water Resources Status Report Page 6 With increasing demand for recycled water, the City has developed a recycled water production model to simulate future recycled water supply and demand. This model will assist in developing parameters for how much recycled water is available for in-City customers and excess recycled water that may be available for outside-City deliveries. Although the City stopped using groundwater for potable purposes in April 2015, groundwater wells remain in an operable, stand-by position should the use of groundwater be required. During Water Year 2018, the City continued its work with a hydrogeologist to site a future well field for a potential groundwater program expansion. The City submitted a Concept Proposal in August 2018, to be considered for the Proposition 1 Groundwater Grant Program. The City received notice from the State Water Resources Control Board inviting the City to submit a full proposal for consideration in 2019. The City’s permit program for the use of the Corporation Yard well expired December 31, 2018 and the well will be closed to the public starting January 1, 2019. After several years of close coordination with County of San Luis Obispo Public Works staff, a County-owned potable water filling station is scheduled to open to the public on January 1, 2019. This filling station is intended to supply the needs of those currently utilizing the City’s Corporation Yard well. III. WATER DEMAND During Water Year 2018, 62 percent of total water use in the City was to support single and multi-family residential uses, 24 percent was to support commercial and other non-residential development, and 14 percent was to support landscape irrigation that is separately metered. Historical water use is summarized below, as well as corresponding population, per capita use rate, and rainfall. The 2018 per capita water use was 100 gallons per capita per day (gpcd). Per capita water use is calculated by dividing total water use in the City by the City’s population. Total water use includes residential and daytime population needs for all uses such as restaurants, hotels, industrial/manufacturing, government/schools, and irrigation. Based on the City’s General Plan Water and Wastewater Management Element policies, the City uses a factor of 117 gpcd to project water required to serve the General Plan’s estimated population in 2035.

WATER RESOURCE AVAILABILITY The following table summarizes the Water Resource Availability based on Water and Wastewater Management Element, Section 3. Water availability for 2018 is 10,130-acre feet. 2018 Water Resource Availability Water Resource Acre Feet Description Salinas & Whale Rock Reservoirs 4,910 Safe Annual Yield 1 Nacimiento Reservoir 5,482 Dependable Yield 2 Recycled Water 238 2017 Annual Usage 3 Siltation from 2010 to 2060 (500) WWME Policy A 4.2.2 4 10,130 2018 Annual Availability NOTES: 1. The City’s Safe Annual Yield model was updated in 2018. 2. Dependable Yield is the contractual amount of water the City has rights to from Nacimiento Reservoir. 3. The quantity of recycled water included is the actual prior year’s recycled water usage (calendar year 2017) per General Plan Water and Wastewater Management Element Policy A 7.2.2. 4. Reservoir siltation is a natural occurrence that reduces storage capacity over long periods, resulting in the reduction of safe annual yield. Page 297 of 422 City of San Luis Obispo 2018 Water Resources Status Report Page 8 V. WATER SUPPLY ACCOUNTING Per General Plan Water and Wastewater Management Element, Section 5, the City accounts for water supplies necessary to meet three specific community needs: x Primary water supply x Reliability reserve x Secondary water supply The City’s primary water supply is defined as the amount of water needed to serve the build-out population identified in the General Plan, Land Use Element (2014). Table 3 in the Land Use Element identifies an urban reserve capacity of 57,200 people. The quantity of water needed for the primary water supply is calculated per WWME Policy A 5.2.2, using 117 gallons per capita per day (gpcd). The City’s reliability reserve provides a buffer for future unforeseen or unpredictable long-term water supply impacts. The quantity of water for the reliability reserve is defined in WWME Policy A 5.2.3, using 20 percent of the existing City population (46,548, 2018 population) at 117 gpcd. The reliability reserve will change over time as the City’s population changes. The reliability reserve concept is included in the City’s Charter (Section 909) which identifies that the water may not be used to serve future development. The City’s secondary water supply is the amount of water remaining from available water resources above those needed to meet the primary water supply and reliability reserve. The secondary supply is identified to meet peak water demand periods or short-term loss of City water supply sources, per General Plan Water and Wastewater Management Element, Policy A 5.2.4. The amendment to the City’s WWME to reflect the update to the City’s Safe Annual Yield model, discussed in Section I of this report, led to the reduction in the City’s available secondary water supply for Water Year 2018. Water supply accounting is summarized in the table below . 2018 Water Supply Accounting (acre feet) Total Primary Water Supply Reliability Reserve Secondary Water Supply 10,130 7,496 1,220 1,414 In summary, despite a significant reduction in safe annual yield from the combined operation of Whale Rock and Salinas Reservoirs, the City maintains a robust water supply portfolio with greater than five years of water available. Per capita water use (obtained from adding up all water used by visitors, residents, commercial uses, etc.) has increased to 100 gallons per capita per day (gpcd) from 95 gpcd the prior year. Recycled water use continues to rise over time. Primary Water Supply = 117 gpcd x City Build-out Population = 117 gpcd x 57,200 x 365 day/year x Acre-Ft/325,851 gal 7,496 Acre-Ft/year Reliability Reserve = 117 gpcd x City Population x 20 percent = 117 gpcd x 46,548 x 365 day/year x Acre-Ft/325,851 gal x 20 percent 1,220 Acre-Ft/year Secondary Water Supply = Current Annual Availability – Primary Water Supply – Reliability Reserve = 10,130 Acre-Ft/yearA – 7,496 Acre- Ft/year – 1,220 Acre-Ft/year 1,414 Acre-Ft/year A 2018 Annual Availability Page 298 of 422 2019 Water Resources Status Report For the Time Period October 1, 2018 through September 30, 2019 Whale Rock Reservoir, August 2019. Prepared by the Water Division of the City of San Luis Obispo, Utilities Department Page 299 of 422 City of San Luis Obispo 2019 Water Resources Status Report Page 2 The City’s 2019 Water Resources Status Report was prepared in accordance with the General Plan, Water and Wastewater Management Element, Policy A5.3.1. The reporting period corresponds to the Water Year (October 1, 2018 through September 30, 2019), the twelve-month period for which precipitation totals are measured designated by the calendar year in which it ends. This report for Water Year 2019 is organized as follows: I. Regulatory and Water Projects Update II. Water Supply III. Water Demand IV. Water Resource Availability V. Water Supply Accounting I. REGULATORY AND WATER PROJECTS UPDATE America’s Water Infrastructure Act America’s Water Infrastructure Act of 2018 (AWIA) was signed on October 23, 2018. AWIA is an update to the Bioterrorism Act of 2002 of the Safe Drinking Water Act. AWIA outlines that community water systems serving 3,300 persons must: x Conduct a Risk and Resilience Assessment (RRA), x Revise Emergency Response Plans (ERP), x Submit a certification letter to EPA, x Review and update at least every five years. The Act requires the City to certify the RRA by June 30, 2021 and the ERP December 30, 2021. Preparation for PSPS Events To protect communities from wildfire, Pacific Gas & Electric (PG&E) notified its customers of its plans to implement precautionary measures during fire season. If extreme fire danger conditions threaten a portion of the PG&E electrical system, high-risk transmission lines may be turned off, resulting in potentially widespread power outages to San Luis Obispo County. PG&E refers to this as a Public Safety Power Shutoff, or PSPS event. According to PG&E, a PSPS event may be necessitated by strong winds, low humidity levels, and critically dry vegetation. PG&E advises these outages will not be localized; regional solutions will be limited because resources are likely going to be scarce on a local, regional and possibly a statewide scale. Nearby communities have already experienced similar PSPS events from their power supplier. Since being informed by PG&E of the potential for PSPS events, the City has worked to prepare for power outages lasting up to seven days or more. In the past, the City has been able to continue to provide uninterrupted water and wastewater service during short-duration power outages and when limited areas were affected by utilizing existing water storage tanks with limited emergency power generation - some of the City’s water and wastewater facilities have permanent emergency generators in place, while others utilized a limited number of mobile generators. With the PSPS notification from PG&E and the changing climate, staff identified additional emergency power resources for the City’s water and wastewater systems to meet this increased duration. Electrical power is the greatest dependency of water systems, with heavy reliance on electricity to run pumps and other system components. Page 300 of 422 City of San Luis Obispo 2019 Water Resources Status Report Page 3 With the support of the City Council in August, the Utilities Department worked to quickly acquire additional temporary emergency generators and make necessary electrical improvements for the Water Treatment Plant, Whale Rock Reservoir, and other water pump stations and sewer lift stations. The City has also been working closely with the County of San Luis Obispo to acquire a generator for the Salinas Booster station that provides water from Salinas reservoir to the City. Installation of permanent generators are planned for 2020. These efforts will bolster the resiliency of the City’s water and wastewater services from any event that could result in loss of electricity. Whale Rock Dam Spillway Assessment The Whale Rock Reservoir and dam are located in San Luis Obispo County at the east boundary of the town of Cayucos. The dam is 266 feet tall with a crest length of 850 feet and crest width of 30 feet impounding Whale Rock Reservoir. The top of dam elevation is 232.2 feet. The Reservoir covers an area of 600 acres and has a maximum storage capacity of 38,967 acre-feet. Dam construction was completed in 1961. Whale Rock was constructed to provide municipal and agricultural water supplies, and fish and wildlife preservation. Over the 58-year life of the Whale Rock Reservoir and dam, the lake has filled to capacity and the spillway has been used 12 times, last spilling in 2005. In 2018, the City contracted with HDR Engineering, Inc. for inspection and assessment of the Whale Rock Dam 850- foot long spillway. The investgation included: 1. Review of design, construction, inspection, analysis, operation and maintenance, and geologic information, as provided by City. 2. Detailed visual inspection of the spillway slabs and walls from upstream of the spillway crest to downstream of the stilling basin. 3. Video/camera inspection of accessible outfall drains and heel drains. 4. Geologic inspection of foundation material adjacent to the spillway. 5. Evaluation of original spillway design versus a modern spillway design. 6. Evaluation of operations, inspection, and surveillance practices. 7. Evaluation of performance of previous repairs. A report was completed in March 2019 with recommendations including maintenance and repair activities for the drainage system and further engineering investigations. The City and its Whale Rock partners, Cal Poly and the California Men’s Colony, will implement corrections as recommended by the California Department of Water Resources, Division of Safety of Dams.

The condition assessments used free-swimming electromagnetic inspection technology, shown in the image below, to locate and identify segments of the pipeline in need of repair. Over 16 miles of 30-inch transmission pipeline from Whale Rock Reservoir was analyzed. The assessment found that 2,610 segments had no abnormalities, and 25 segments had varying deficiencies (broken bar wraps or cylinder wall loss). The Salinas pipeline condition assessment analyzed 1.25 miles of pipeline originally installed in 1940s. Results of the assessment were described in a May 2019 report revealing 222 of the total 236 segments had no abnormalities, and 14 segments had varying deficiencies. Funding is programmed to address these pipeline deficiencies in the 2020-21 fiscal year. Conceptual image of Electromagnetic Inspection Technology used to assess the Whale Rock and Salinas Reservoir transmission pipelines. Sustainable Groundwater Management Act The use of groundwater contributes to resiliency in the City’s water supply portfolio by offering a potable water source to complement the City’s three surface water supplies. The Sustainable Groundwater Management Act (SGMA) is a statewide law that requires Groundwater Sustainability Agencies (GSA) to adopt groundwater management plans that outline actions needed to return groundwater basins to sustainable levels of pumping and recharge. In May 2017, the City Council approved Resolution 10796 authorizing the City to become a Groundwater Sustainability Agency (GSA) for the San Luis Valley Groundwater Basin for the area that lies beneath and within the City’s jurisdictional boundaries. In February 2019, the City Council, acting as the San Luis Valley Basin – City of San Luis Obispo Groundwater Sustainability Agency, approved the Notification of Intent to initiate development of a Groundwater Sustainability Plan (GSP) for the San Luis Obispo Valley Groundwater Basin. The City is working in collaboration with the County of San Luis Obispo GSA to create a single Groundwater Sustainability Plan (GSP) that provides full coverage of the San Luis Valley Groundwater Basin. To get additional information, to sign up for the interested stakeholder email list, or to see materials for past or upcoming meetings related to the GSP development, interested parties are encouraged to visit www.slowaterbasin.com. The San Luis Valley GSP must be submitted to California Department of Water Resources (DWR) by January 31, 2022. Page 302 of 422 City of San Luis Obispo 2019 Water Resources Status Report Page 5 Leak Detection In September 2019, staff from the City’s Water Distribution section field tested acoustic correlation equipment by Echologics on an existing cast iron water main on Bebee Street. Acoustic sensors were attached to water valves to measure the speed at which sounds waves travel along the pipe. These sensors effectively listen to water flowing through the pipe and can hear when water is escaping through a leak. The location can then be identified. Using this tool regularly the City will be able to: x More accurately locate small leaks, resulting in less damage to surrounding infrastructure x Further optimize its capital spending x Minimize water main breaks, water loss, and damage from leaks x Better manage aging water infrastructure The City’s correlator can identify leaks that have not come to the surface yet, and pinpoint leak location within about two feet. The City’s Water Distribution team is looking forward to utilizing this device to reduce water loss, find leaks before they create damage, reduce road repair work, and enhance proactive maintenance of the water distribution system. Waterline Replacement Projects Replacement of water distribution pipes and related facilities is an ongoing program aimed to address aging, substandard, and deteriorating infrastructure, with the added benefit of reducing customer impacts associated with emergency repairs. Waterline breaks occur with more frequency with aging waterlines, and the resulting repairs are disruptive to the public and expensive to repair. The main objectives of this program are to ensure reliable water service, reduce the need for emergency repairs, and to enhance available fire flows. During the 2019 Water Year, the City completed replacement of approximately 5,000 lineal feet of waterline on Pacific (from Nipomo to Walker), Boysen (from Chorro to Hwy. 1), Chorro (from Pismo to Pacific) and Sierra (from Ella to Bishop) streets at a cost of approximately $2.3 million. The Casa/Stenner/Murray Waterline Replacement Project proposes replacement of over 3,100 lineal feet of aged waterline on Casa, Stenner, Murray (from Hathway to Santa Rosa) and the intersections of Chorro/Meinecke and Chorro/Murray. The construction cost of the project is approximately $2 million. The waterlines replaced with this project are undersized and deteriorated. Their replacement will eliminate capacity limitations for Sierra Vista Hospital, reduce the likelihood of service interruptions due to leaks, and improve water flow for fire protection. Short-Term Water Sales At a March 2019 study session, City Council provided direction to staff related to short-term water sales. A potential recipient of this program may be Cal Poly while the university secures a permanent water supply specifically related to housing production. Council supported broadening existing policy language for the City to supply non-potable water (raw water or recycled water) through a short-term agreement for agricultural purposes. Short-term agreements would be crafted to include provisions for service interruption or reduction, due to operational issues or climatic events, low reservoir levels, increased Page 303 of 422 City of San Luis Obispo 2019 Water Resources Status Report Page 6 water demand forecasting, or water quality deterioration. Meaning, during a water shortage emergency, City water deliveries would be prioritized above those included in a short-term sales agreement. The City is uniquely positioned to assist Cal Poly in meeting its 2035 Master Plan goals as both a regional water partner and in support of City goals, particularly as it relates to additional on-campus housing. Cal Poly currently only has one source of potable water, which is raw water from Whale Rock Reservoir that is treated at the City’s water treatment plant and delivered to the campus as part of a contract between the City and Cal Poly. Any contracts for short-term water sales would be brought to the City Council for consideration. II. WATER SUPPLY Per the General Plan Water and Wastewater Management Element, Policy A2.2.1, the City uses multiple water sources to meet its water supply needs. The City has four primary water supply sources including Whale Rock Reservoir, Salinas Reservoir, Nacimiento Reservoir, and recycled water. Groundwater serves as a fifth supplemental source. The supply per source for Water Year 2019 (from October 1, 2018 to September 30, 2019) is summarized below. 2019 City Water Supply by Source (in acre feet) Nacimiento Reservoir Whale Rock Reservoir 2 Recycled Water Salinas Reservoir Groundwater 3 Total City Water Demand 3,406 350 201 805 0 4,762 71.5% 7.4% 4.2% 16.9% 0% 100% Notes: 1. Values are rounded. 2. Water delivered to Cal Poly State University is excluded from the City’s water demand. 3. Groundwater was not used for potable purposes during Water Year 2019. During Water Year 2019, 71.5 percent of the City’s total water demand was met by Nacimiento Reservoir. San Luis Obispo County operates and maintains the water delivery system from Nacimiento Reservoir to participating agencies (currently the cities of Paso Robles and San Luis Obispo, Atascadero Mutual Water Company, Templeton Community Services District, County Service Area 10A [Cayucos], Santa Margarita Ranch, and Bella Vista Mobile Home Park). The Nacimiento Project Commission provides oversight to project operations, maintenance, and the project budget. The Commission is made up of representatives from each of the four agencies’ governing boards and a County Representative who is a member of the County Board of Supervisors who also sits on the Board of Directors for the Flood Control District. During Water Year 2019, the City utilized a total of 1,155-acre feet from Salinas and Whale Rock reservoirs, meeting 24.3 percent of total City water demand. The City pays the County of San Luis Obispo Flood Control and Water Conservation District (County) to provide oversight, operations, and maintenance of Salinas Reservoir and related water delivery facilities. The City provides oversight, operations, and maintenance of the Whale Rock Reservoir for the benefit of the Whale Rock Commission, a joint powers agency made up of Cal Poly State University, California Men’s Colony, and the City. For Water Year 2019, the City delivered 201-acre feet of recycled water for landscape irrigation and construction water. This equates to 4.21 percent of total City water demand. New recycled water customers include Coast BMW, HASLO for the Iron Works housing project, and Prado Day Center. Recycled Water for Construction (in acre feet) 2017 2018 2019 19 36 20 Note: Values are rounded. Page 304 of 422 City of San Luis Obispo 2019 Water Resources Status Report Page 7 Construction water use decreased from 36-acre feet in Water Year 2018 to 20-acre feet in Water Year 2019. Construction of the Water Resource Recovery Facility (WRRF) Project began in 2019 and will take approximately three years to complete. When complete, the new technology used at the WRRF will reduce overall wastewater treatment time by approximately 20 hours, from approximately 28 hours to eight hours, providing a shortened timeframe for when wastewater comes into the plant and when it can be sent out into the recycled water system for irrigation use. Although the City suspended using groundwater for potable purposes in April 2015, groundwater wells remain in an operable, stand-by position should the use of groundwater be needed. During Water Year 2019, the City continued its work with a hydrogeologist to site a future well field for a potential groundwater program expansion. The City received notice from the State Water Resources Control Board inviting the City to submit a full proposal for the Proposition 1 Groundwater Grant Program for consideration in 2019. The City was notified in October 2019 that pending negotiation with the State Board, it will be receiving the $2 million planning-phase grant for installation of monitoring wells and for monitoring groundwater quality. These are necessary steps in reestablishing the City’s groundwater program. The planning phase will continue through 2020 with implementation planned for 2021. III. WATER DEMAND During Water Year 2019, 60.48 percent of total water use in the City was to support single and multi- family residential uses, 28.36 percent was to support commercial and other non-residential development, and 11.16 percent was to support landscape irrigation that is separately metered. Historical water use is summarized below, as well as corresponding population, per capita use rate, and rainfall. The 2019 per capita water use was 91 gallons per capita per day (gpcd). Per capita water use is calculated by dividing total water use in the City by the City’s population. Total water use includes residential and daytime population needs for all uses such as restaurants, hotels, industrial/manufacturing, government/schools, Salinas Dam spillway, February 2019. Page 305 of 422 City of San Luis Obispo 2019 Water Resources Status Report Page 8 and irrigation. Based on the City’s General Plan Water and Wastewater Management Element policies, the City uses a factor of 117 gpcd to project water required to serve the General Plan’s estimated population in 2035.

The quantity of recycled water included is the actual prior year’s usage (calendar year 2018) per General Plan Water and Wastewater Management Element Policy A 7.2.2. 4. Reservoir siltation is a natural occurrence that reduces storage capacity over long periods, resulting in the reduction of safe annual yield. Page 307 of 422 City of San Luis Obispo 2019 Water Resources Status Report Page 10 V. WATER SUPPLY ACCOUNTING Per General Plan Water and Wastewater Management Element, Section 5, the City accounts for water supplies necessary to meet three specific community needs: x Primary water supply x Reliability reserve x Secondary water supply The City’s primary water supply is defined as the amount of water needed to serve the build-out population identified in the General Plan, Land Use Element (2014). Table 3 in the Land Use Element identifies an urban reserve capacity of 57,200 people. The quantity of water needed for the primary water supply is calculated per WWME Policy A 5.2.2, using 117 gallons per capita per day (gpcd). The City’s reliability reserve provides a buffer for future unforeseen or unpredictable long-term water supply impacts. The quantity of water for the reliability reserve is defined in WWME Policy A 5.2.3, using 20 percent of the existing City population (46,802, 2019 population) at 117 gpcd. The reliability reserve will change over time as the City’s population changes. The reliability reserve concept is included in the City’s Charter (Section 909) which identifies that the water may not be used to serve future development. The City’s secondary water supply is the amount of water remaining from available water resources above those needed to meet the primary water supply and reliability reserve. The secondary supply is identified to meet peak water demand periods or short-term loss of City water supply sources, per General Plan Water and Wastewater Management Element, Policy A 5.2.4. Water supply accounting is summarized in the table below and shown in Appendix A. 2019 Water Supply Accounting (acre feet) Total Primary Water Supply Reliability Reserve Secondary Water Supply 10,136 7,496 1,227 1,413 In summary, the City maintains a robust water supply portfolio with greater than five years of water available. Per capita water use (obtained from adding up all water used by visitors, residents, commercial uses, etc.) decreased during the 2019 Water Year to 91 gallons per capita per day (gpcd) from 100 gpcd during the 2018 Water Year. Primary Water Supply = 117 gpcd x City Build-out Population = 117 gpcd x 57,200 x 365 day/year x Acre-Ft/325,851 gal 7,496 Acre-Ft/year Reliability Reserve = 117 gpcd x 2019 City Population x 20 percent = 117 gpcd x 46,802 x 365 day/year x Acre-Ft/325,851 gal x 20 percent 1,227 Acre-Ft/year Secondary Water Supply = Current Annual Availability – Primary Water Supply – Reliability Reserve = 10,130 Acre-Ft/yearA – 7,496 Acre- Ft/year – 1,220 Acre-Ft/year 1,413 Acre-Ft/year A 2018 Annual Availability Page 308 of 422 City of San Luis Obispo 2019 Water Resources Status Report Page 11 Appendix A.

Page 310 of 422 City of San Luis Obispo 2020 Water Resources Status Report Page 2 The City’s 2020 Water Resources Status Report was prepared in accordance with the General Plan, Water and Wastewater Management Element, Policy A5.3.1. The reporting period corresponds to the 2020 Water Year (October 1, 2019 through September 30, 2020), the twelve-month period for which precipitation totals are measured designated by the calendar year in which it ends. This report provides a summary of the following for the 2020 Water Year: I. Regulatory and Water Capital Projects Update II. Water Supply III. Water Demand IV. Water Resource Availability V. Water Supply Accounting I. CAPITAL PROJECTS AND REGULATORY UPDATE The City completed two large water infrastructure projects during the 2020 Water Year and began the implementation of a third project with capital improvements totaling over $18.7 million. These projects are summarized below along with key regulatory updates related to the Sustainable Groundwater Management Act and the upcoming update to the City’s Urban Water Management Plan. Disinfection Byproduct Reduction & Water Treatment Plant Pipe G allery Improvement Project In August, the City completed the approximately $2.6 million Disinfection Byproduct Reduction and Water Treatment Plant (WTP) Pipe Gallery Improvements Project. The Project included modifications at two potable water storage tanks (Clearwell #2 at the WTP and Edna Saddle Tank) for the installation of specialty equipment (mixers, aerators, and ventilators) to effectively reduce disinfection byproducts to improve water quality and meet regulatory requirements. The Project also included replacement of corroded pipe within the pipe gallery at the WTP, and the replacement of a sections of effluent line and additional valving to provide a means for improved maintenance flexibility within the pipe gallery. Water Energy Efficiency Project In November 2019, the City Council approved the Water Energy Efficiency project that includes $14.3 million of improvements to the City’s Water Treatment Plant. The benefits of the project include: 1. Contribute to the City’s sustainability goals and advancement toward Zero Net Energy. 2. Reduce energy consumption and greenhouse gas emissions. 3. Replace obsolete equipment and components. 4. Improve ability to perform maintenance. 5. Improve reliability of achieving permit compliance. 6. Increase operational reliability, flexibility, and redundancy. 7. Reduced staff requirements for manual operation. It is estimated that implementation of the Water Energy Efficiency Project will result in a reduction of energy usage of over 33 percent annually from 2019 WTP operations. The project is approximately 50 percent complete, with Phase 1 Installation of new Ozone Generators. Installation of new Dilution Air Dryers. Page 311 of 422 City of San Luis Obispo 2020 Water Resources Status Report Page 3 Commissioning planned for early 2021. The Project is scheduled to be complete in mid-2021. Waterline Replacement Projects During the 2020 Water Year, the City completed replacement of over 3,000 lineal feet of waterline on Casa, Stenner, and Murray Streets surrounding Sierra Vista Hospital at a cost of approximately $1.7 million. Replacement of water distribution pipes and related facilities is an ongoing program aimed to address aging, substandard, and deteriorating infrastructure, with the added benefit of reducing customer impacts associated with emergency repairs. Waterline breaks occur with more frequency with aging waterlines, and the resulting repairs are disruptive to the public and expensive to repair. The main objectives of this program are to ensure reliable water service, reduce the need for emergency repairs, and to enhance available fire flows. Capital Improvements at Whale Rock Reservoir At the request of the California Department of Water Resources, Division of Safety of Dams, the City began preparing plans and specifications for a Spillway Underdrain Repair project at the Whale Rock dam, as well as the first draft of the Emergency Action Plan update, during the 2020 Water Year. The Plan is under review internally by staff. The City performs this work with its Whale Rock Commission partners, Cal Poly State University and the California Men’s Colony. Ongoing capital improvements aimed at maintaining infrastructure safety and reliability include replacement of pressure relief valves for Whale Rock Pump Station B, replacement of 2,000 feet of fence- line around Whale Rock Reservoir, and replacement of the Reservoir’s boathouse structure. Sustainable Groundwater Management Act The use of groundwater will increase resiliency in the City’s water supply portfolio by offering a local water source to complement the City’s three surface water supplies. The Sustainable Groundwater Management Act (SGMA) is a statewide law that requires Groundwater Sustainability Agencies (GSA) to adopt groundwater management plans that outline actions needed to return groundwater basins to sustainable levels of pumping and recharge. Sunset bike ride at Whale Rock Reservoir. Page 312 of 422 City of San Luis Obispo 2020 Water Resources Status Report Page 4 The City is working with the County of San Luis Obispo GSA to create a single Groundwater Sustainability Plan (GSP) that provides full coverage of the San Luis Valley Groundwater Basin. To-date, the first seven chapters of the GSP have been drafted and released to the public for review. To get additional information, to sign up for the interested stakeholder email list, or to see materials for past or upcoming meetings related to the GSP development, interested parties are encouraged to visit www.slowaterbasin.com. The San Luis Valley GSP must be submitted to California Department of Water Resources (DWR) by January 31, 2022. 2020 Urban Water Management Plan Guidelines California’s Department of Water Resources issued its draft 2020 Urban Water Management Plan Guidelines in August 2020. The State’s new requirements include: 1. Water loss audit results that characterize distribution system losses. 2. Procedures for conducting annual water supply and demand assessment. 3. Five-year drought risk asssessment. 4. Energy analysis. 5. A six-phase water shortage contingency plan. Many of these new State requirements are already part of the City’s water planning, including the preparation of this Water Resource Status Report annually. Staff will present more information to the City Council on the new requirements at a March 2021 Study Session, with consideration of the City’s 2020 Urban Water Management Plan in June of 2021. II. WATER SUPPLY Per the General Plan Water and Wastewater Management Element, Policy A2.2.1, the City uses multiple water sources to meet its water supply needs. The City has four primary water supply sources including Whale Rock Reservoir, Salinas Reservoir, Nacimiento Reservoir, and recycled water. Groundwater serves as the City’s fifth supplemental water source. Substantial work efforts are being made to better understand the City’s groundwater supplies and how they may be fully utilized in the future. The quantity of water supplied by each water source for Water Year 2020 (from October 1, 2019 to September 30, 2020) is summarized in Table 1. Table 1: City Water Supply by Source during the 2020 Water Year (in acre-feet) Nacimiento Reservoir Whale Rock Reservoir 2 Recycled Water Salinas Reservoir Groundwater 3 Total City Water Demand 1,562 777 237 2,154 0 4,730 33% 16% 5% 46% 0% 100% Notes: 1. Values are rounded. 2. Water delivered to Cal Poly State University is excluded from the City’s water demand. 3. Groundwater was not used for potable purposes during Water Year 2020. During Water Year 2020, 33 percent of the City’s total water demand was met by Nacimiento Reservoir. San Luis Obispo County operates and maintains the water delivery system from Nacimiento Reservoir to participating agencies (currently the cities of Paso Robles and San Luis Obispo, Atascadero Mutual Water Company, Templeton Community Services District, County Service Area 10A [Cayucos], Santa Margarita Ranch, and Bella Vista Mobile Home Park). The Nacimiento Project Commission provides oversight to project operations, maintenance, and the project budget. The Commission is made up of representatives Page 313 of 422 City of San Luis Obispo 2020 Water Resources Status Report Page 5 from each of the four agencies’ governing boards and a County Representative who is a member of the County Board of Supervisors who also sits on the Board of Directors for the Flood Control District. During Water Year 2020, water demand totaled 4,730 acre-feet, below the ten-year average of 5,004 acre-feet (for 2011 to 2020), and the lowest total water demand since 2015. This is likely due to the impacts of COVID-19. The City utilized a total of 2,931 acre-feet from Salinas and Whale Rock reservoirs, meeting 62 percent of total City water demand. The City pays the County of San Luis Obispo Flood Control and Water Conservation District (County) to provide oversight, operations, and maintenance of Salinas Reservoir and related water delivery facilities. The City provides oversight, operations, and maintenance of the Whale Rock Reservoir for the benefit of the Whale Rock Commission, a joint powers agency made up of Cal Poly State University, California Men’s Colony, and the City. For Water Year 2020, the City delivered 237acre-feet of recycled water for landscape irrigation and construction water. This equates to five percent of total City water demand. New recycled water customers during the 2020 Water Year include several properties in the Orcutt Specific Plan Area. Although the City suspended using groundwater for potable purposes in April 2015, groundwater wells remain in an operable, stand-by position should the use of groundwater be needed. In July of 2020, the City received a nearly $2 million planning-phase grant, funded through Proposition 1, to study Tetrachloroethylene (PCE) contamination of the groundwater basin. A detailed understanding of the extent of PCE contamination and remediation options are necessary steps in fully utilizing the City’s groundwater pumping opportunities. The planning phase will continue through 2021 with implementation planned for 2022. III. WATER DEMAND During Water Year 2020, the breakdown of water use in the City by sector is as follows: x 65.8 percent of water use supported single and multi-family residential uses, or 3,112 acre-feet, x 20.8 percent of water use supported commercial and other non-residential uses, or 984 acre-feet, x 8.3 percent of water use supported separately metered landscape irrigation (potable water), or 393 acre-feet, x 4.4 percent of water use supported separately metered landscape irrigation (recycled water), or 208 acre-feet, and x 0.7 percent of water use supported construction (recycled water), or 33 acre-feet. Compared to the prior water year, total City water demand for single and multi-family residential uses increased from 60.5 percent in Water Year 2019 to 65.8 percent in Water Year 2020, likely due to both remote work and remote learning during COVID-19. During the same timeframe, water demand for commercial uses decreased from 28.4 percent in Water Year 2019 to 20.8 percent in Water Year 2020. Historical water use is summarized in Table 2, as well as corresponding population, per capita use rate, and rainfall. The 2020 per capita water use was 92 gallons per capita per day (gpcd). Per capita water use is calculated by dividing total water use (including recycled water) in the City by the City’s population. Total water use includes residential and daytime population needs for all uses such as restaurants, hotels, industrial/manufacturing, government/schools, and irrigation. Based on the City’s General Plan Water Page 314 of 422 City of San Luis Obispo 2020 Water Resources Status Report Page 6 and Wastewater Management Element policies, the City uses a factor of 117 gpcd to project water required to serve the General Plan’s estimated population in 2035. The City’s water supply reservoirs are in different watersheds, therefore rainfall at various locations within San Luis Obispo County benefits the City. As shown in Table 3, during Water Year 2020, two reservoir locations (Rocky Butte and Salinas Dam) received more than the annual average. The remaining location, Hwy 46 and W 7 Mile Road, Cambria, CA, received less than average rainfall.

Following the end of the drought in 2016, the City updated the Safe Annual Yield model for Whale Rock and Salinas Reservoirs incorporating rainfall data and three climate change scenarios. In 2018, the City recognized the reduction from 6,940 acre-feet to 4,910 acre-feet in Safe Annual Yield (-2,030 acre-feet). IV. WATER RESOURCE AVAILABILITY The following table summarizes the Water Resource Availability based on Water and Wastewater Management Element, Section 3. Water availability for Water Year 2020 is 10,107 acre-feet.

Page 316 of 422 City of San Luis Obispo 2020 Water Resources Status Report Page 8 V. WATER SUPPLY ACCOUNTING Per General Plan Water and Wastewater Management Element (WWME), Section 5, the City accounts for water supplies necessary to meet three specific community needs: x Primary water supply x Reliability reserve x Secondary water supply Primary water supply is defined as the amount of water needed to serve the City’s future residential and non-residential water demand, based on the population identified in the General Plan, Land Use Element (2014). Table 3 in the Land Use Element identifies an urban reserve capacity of 57,200 people1. The quantity of water needed for the primary water supply is calculated per WWME Policy A 5.2.2, using 117 gallons per capita per day (gpcd). The City’s reliability reserve is defined as the buffer for future unforeseen or unpredictable long-term water supply impacts. The quantity of water for the reliability reserve is defined in WWME Policy A 5.2.3, using 20 percent of the existing City population (45,920, 2020 population) at 117 gpcd. Based on this policy, the reliability reserve will change over time as the City’sactual population changes. The reliability reserve concept is included in the City’s Charter (Section 909) which identifies that the water may not be used to serve future development. The City’s secondary water supply is defined as the amount of water remaining from available water resources above those needed to meet the primary water supply and reliability reserve. The secondary supply is identified to meet peak water demand periods or short-term loss of City water supply sources, per WWME Policy A 5.2.4. Water supply accounting for the 2020 Water Year is summarized i n the table below and shown in Appendix A. 1 The City’s population projection of 57,200 persons, from the General Plan Land Use Element, is based one percent growth annually between 2014 and 2035. By policy, certain housing types and areas are excluded from this growth rate and projection (affordable housing, etc.). The City’s estimated Primary Water Supply need is based on projected population but encompasses all water demand in the City (residential, non-residential, and irrigation). In WY 2020, single-family and multi-family residential water demand was 65.8 percent of total City water demand. 2020 Water Supply Accounting Primary Water Supply = 117 gpcd x City Build-out Population, in acre-feet per year 117 gpcd x 57,200 x 365 day/year x acre-ft/325,851 gallons = 7,496 acre-ft per year Reliability Reserve = 117 gpcd x 2020 City Population x 20 percent, in acre-feet per year 117 gpcd x 45,920 x 365 day/year x acre-ft/325,851 gallons x 20 percent = 1,204 acre-ft per year Secondary Water Supply = Current Annual Availability – Primary Water Supply – Reliability Reserve 10,107 acre-ft/year A – 7,496 acre-ft/year – 1,204 Acre-Ft/year = 1,407 acre-ft per year A 2020 Annual Water Resource Availability from table above.

In summary, the City maintains a robust water supply portfolio with greater than five years of water available. Per capita water use (obtained from adding up all water used by visitors, residents, commercial uses, etc.) decreased during the 2020 Water Year to 92 gallons per capita per day (gpcd) from 93 gpcd during the 2019 Water Year. City population figures, and associated gallons per capita per day, reported in the 2019 Water Resource Status Report were updated from Department of Finance data.

Tradúzcalo o hable con alguien que lo entienda bien.Page 354 of 422 Quality First Once again, we are pleased to present our annual water quality report covering all testing performed between January 1 and December 31, 2020. As in years past, we are committed to delivering the best- quality drinking water possible. To that end, we remain vigilant in meeting the challenges of new regulations, source water protection, water conservation, and community outreach and education while continuing to serve the needs of all our water users. Thank you for allowing us the opportunity to serve you and your family. We encourage you to share your thoughts with us on the information contained in this report. After all, well-informed customers are our best allies. Q qualit sour ser f W Where Does My Water Come From? The City of San Luis Obispo is fortunate to have several sources of water. The Salinas Reservoir (also known as Santa Margarita Lake, eight miles east of Santa Margarita), Whale Rock Reservoir (Cayucos), and Nacimiento Lake (16 miles northwest of Paso Robles) are the main supplies. The surface water from the three lakes is treated at the Stenner Creek Water Treatment Plant. During 2020, the treatment plant delivered 1.71 billion gallons of water to San Luis Obispo. Public Meetings City Council meetings are held on the first and third Tuesday of each month at 6:00 p.m. at City Hall, 990 Palm Street, San Luis Obispo. A public comment period is held at the beginning of each meeting. Emergency Public Meeting Procedure due to COVID-19 Based on the threat of COVID-19, as reflected in the Proclamations of Emergency issued by the Governor of the State of California, the San Luis Obispo County Emergency Services Director, and the City Council of the City of San Luis Obispo as well as the Governor’s Executive Order N-29-20 issued on March 17, 2020, relating to the convening of public meetings in response to the COVID-19 pandemic, the City of San Luis Obispo will be holding all public meetings via teleconference. There will be no physical location for the public to attend the meeting. Using the most rapid means of communication available at this time, members of the public are encouraged to participate in council meetings in the following ways: View the webinar. Information is available on the city’s website at https://www. slocity.org/ The Benefits of Fluoridation Our water system treats your water by adding fluoride to the naturally occurring level to help prevent dental caries in consumers. State regulations require the fluoride levels in the treated water be maintained within a range of 0.6 to 1.2 ppm with an optimum dose of 0.7 ppm. Our monitoring showed that the fluoride levels in the treated water ranged from 0.0 to 0.9 ppm with an average of 0.59 ppm. Information about fluoridation, oral health, and current issues is available from http://www.swrcb. ca.gov/drinking_water/certlic/drinkingwater/Fluoridation.shtml. Important Health Information Some people may be more vulnerable to contaminants in drinking water than the general population. Immunocompromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants may be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. The U.S. EPA/CDC (Centers for Disease Control and Prevention) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline at (800) 426-4791 or http://water.epa.gov/drink/ hotline. m their DC on) the her m For more information about this report, or for any questions relating to your drinking water, please contact Jason Meeks, Water Treatment Plant Supervisor, at (805) 781-7566 or jmeeks@slocity.org. QUESTIONS? Source Water Assessment Assessments of the drinking water sources for the City of San Luis Obispo have been conducted. These sources include Salinas Reservoir, Whale Rock Reservoir, Nacimiento Lake, and Pacific Beach Well. These sources are considered most vulnerable to the following activities not associated with any detected contaminants: grazing, managed forests, recreational areas, septic systems, sewer collection systems, gas stations. A copy of the complete assessment is available from the SWRCB Division of Drinking Water, 1180 Eugenia Place, Suite 200, Carpinteria, California, 93013 or the City of San Luis Obispo, 879 Morro Street, San Luis Obispo, California, 93401. Page 355 of 422 Substances That Could Be in Water The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and, in some cases, radioactive material and can pick up substances resulting from the presence of animals or from human activity. In order to ensure that tap water is safe to drink, the U.S. Environmental Protection Agency (U.S. EPA) and the State Water Resources Control Board (State Board) prescribe regulations that limit the amount of certain contaminants in water provided by public water systems. The U.S. Food and Drug Administration regulations and California law also establish limits for contaminants in bottled water that provide the same protection for public health. Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. Contaminants that may be present in source water include: Microbial Contaminants, such as viruses and bacteria, that may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife; Inorganic Contaminants, such as salts and metals, that can be naturally occurring or can result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming; Pesticides and Herbicides that may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses; Organic Chemical Contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production and which can also come from gas stations, urban stormwater runoff, agricultural applications, and septic systems; Radioactive Contaminants that can be naturally occurring or can be the result of oil and gas production and mining activities. More information about contaminants and potential health effects can be obtained by calling the U.S. EPA’s Safe Drinking Water Hotline at (800) 426-4791. Lead in Home Plumbing If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. We are responsible for providing high-quality drinking water, but we cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to two minutes before using water for drinking or cooking. (If you do so, you may wish to collect the flushed water and reuse it for another beneficial purpose, such as watering plants.) If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline at (800) 426-4791 or at www.epa.gov/safewater/lead. Water Treatment Process The treatment process consists of a series of steps referred to as conventional surface water treatment. First, raw water is drawn from our water sources and sent to an ozone contact basin, which provides primary disinfection and oxidation of the high iron levels that are present in the water. The water then goes to a mixing tank, where aluminum sulfate and cationic polymer are added. The addition of these substances causes small particles (called floc) to adhere to one another, making them heavy enough to settle into a basin, from which sediment is removed. At this point, the water is filtered through layers of anthracite and silicate sand. As smaller suspended particles are removed, turbidity disappears and clear water emerges. Chlorine is added as a precaution against any bacteria that may still be present. We carefully monitor the amount of chlorine, adding the lowest quantity necessary to protect the safety of your water without compromising taste. Finally, fluoride (to prevent tooth decay) and a corrosion inhibitor (to protect distribution system pipes) are added before the water is pumped to sanitized underground reservoirs and water tanks and into your home or business. Page 356 of 422 Test ResultsDrinking water is monitored for many different kinds of substances on a very strict sampling schedule. The water delivered must meet specific health standards. This report only shows substances that were detected in the city’s drinking water (a complete list of all analytical results is available upon request). Remember that detecting a substance does not mean the water is unsafe to drink; the goal is to keep all detects below respective maximum allowed levels.The state recommends monitoring for certain substances less than once per year because the concentrations of these substances do not change frequently. In these cases, the most recent sample data are included, along with the year in which the sample was taken.The City of San Luis Obispo participated in the fourth stage of the U.S. EPA’s Unregulated Contaminant Monitoring Rule (UCMR4) program by performing additional tests on our drinking water. UCMR4 sampling benefits the environment and public health by providing the U.S. EPA with data on the occurrence of contaminants suspected to be in drinking water in order to determine if U.S. EPA needs to introduce new regulatory standards to improve drinking water quality. Unregulated contaminant monitoring data are available to the public, so please feel free to contact us if you are interested in obtaining that information. If you would like more information on the U.S. EPA’s Unregulated Contaminant Monitoring Rule, please call the Safe Drinking Water Hotline at (800) 426-4791.REGULATED SUBSTANCESSUBSTANCE(UNIT OF MEASURE)YEARSAMPLEDMCL[MRDL]PHG(MCLG)[MRDLG]AMOUNTDETECTEDRANGELOW-HIGHVIOLATION TYPICAL SOURCEAluminum (ppm) 2020 1 0.6 0.079 0.06–0.1 No Erosion of natural deposits; residue from some surface water treatment processesChlorine (ppm) 2020 [4.0 (as Cl2)] [4 (as Cl2)] 0.81 0.02–1.6 No Drinking water disinfectant added for treatmentControl of DBP Precursors [TOC]1 (percent removal)2020 TT NA 27 3–54 No Various natural and human-made sourcesFluoride2 (ppm) 2020 2.0 1 0.59 ND–0.9 No Erosion of natural deposits; water additive that promotes strong teeth; discharge from fertilizer and aluminum factoriesGross Alpha Particle Activity (pCi/L)2011 15 (0) 0.0145 ND–0.029 No Erosion of natural depositsHaloacetic Acids3 (ppb) 2020 60 NA 39 16–77 No By-product of drinking water disinfectionHexavalent Chromium (ppb) 2015 1040.02 2.0 ND–12.0 No Discharge from electroplating factories, leather tanneries, wood preservation, chemical synthesis, refractory production, and textile manufacturing facilities; erosion of natural depositsTTHMs [Total Trihalomethanes]3 (ppb)2020 80 NA 43 17–74 No By-product of drinking water disinfectionTurbidity5 (NTU) 2020 TT NA 0.18 0.05–0.18 No Soil runoffTurbidity (lowest monthly percent of samples meeting limit)2020 TT = 95% of samples meet the limitNA 100 NA No Soil runoffTap water samples were collected for lead and copper analyses from sample sites throughout the communitySUBSTANCE(UNIT OF MEASURE)YEARSAMPLED ALPHG(MCLG)AMOUNT DETECTED (90TH %ILE)SITES ABOVE AL/TOTAL SITES VIOLATION TYPICAL SOURCECopper (ppm) 2019 1.3 0.3 0.188 0/30 No Internal corrosion of household plumbing systems; erosion of natural deposits; leaching from wood preservativesLead (ppb) 2019 15 0.2 ND 0/30 No Internal corrosion of household water plumbing systems; discharges from industrial manufacturers; erosion of natural depositsPage 357 of 422 SECONDARY SUBSTANCESSUBSTANCE(UNIT OF MEASURE)YEARSAMPLED SMCLPHG(MCLG)AMOUNTDETECTEDRANGELOW-HIGHVIOLATION TYPICAL SOURCEAluminum (ppb) 2020 200 NS 0.079 0.06–0.1 No Erosion of natural deposits; residual from some surface water treatment processesChloride (ppm) 2020 500 NS 16 16–16 No Runoff/leaching from natural deposits; seawater influenceSpecific Conductance (µmho/cm) 2020 1,600 NS 467 467–467 No Substances that form ions when in water; seawater influenceSulfate (ppm) 2020 500 NS 78.2 78.2–78.2 No Runoff/leaching from natural deposits; industrial wastesUNREGULATED AND OTHER SUBSTANCES 6SUBSTANCE(UNIT OF MEASURE)YEARSAMPLEDAMOUNTDETECTEDRANGELOW-HIGHTYPICAL SOURCEHardness (ppm) 2020 184 120–300 Polyvalent cations present in the water, generally magnesium and calcium, which are naturally occurringSodium (ppm) 2020 23 23–23 Naturally occurring1 Total organic carbon (TOC) has no health effects. However, TOC provides a medium for the formation of disinfection by-products such as TTHMs and HAA5s. The city’s TOC reduction requirement was 25 to 35 percent based on a running annual average calculated quarterly.2 Our water system treats your water by adding fluoride to the naturally occurring level to help prevent dental caries in consumers. State regulations require the fluoride levels in the treated water be maintained within a range of 0.6 to 1.2 ppm, with an optimum dose of 0.7 ppm. Our monitoring showed that the fluoride levels in the treated water ranged from below detection limits to 0.9 ppm, with an average of 0.59 ppm. Information about fluoridation, oral health, and current issues is available from http://www.swrcb.ca.gov/drinking_water/certlic/drinkingwater/Fluoridation.shtml.3 Regulatory compliance is determined based on the locational running annual average (LRAA). Additional sample results are included in this report, along with regulatory compliance results.4 There is currently no MCL for hexavalent chromium. The previous MCL of 10 ppb was withdrawn on September 11, 2017.5 Turbidity is a measure of the cloudiness of the water. We monitor it because it is a good indicator of the effectiveness of our filtration system.6 Unregulated contaminant monitoring helps U.S. EPA and the State Water Resources Control Board determine where certain contaminants occur and whether the contaminants need to be regulated.Definitions90th %ile: The levels reported for lead and copper represent the 90th percentile of the total number of sites tested. The 90th percentile is equal to or greater than 90% of our lead and copper detections.AL (Regulatory Action Level): The concentration of a contaminant which, if exceeded, triggers treatment or other requirements that a water system must follow.MCL (Maximum Contaminant Level): The highest level of a contaminant that is allowed in drinking water.

A water shortage could occur due to drought, earthquake, infrastructure failure, or other emergency. Drought may occur with unpredictable frequency, intensity, and duration. An update to the City’s Water Conservation Ordinance (Chapter 13.07 of the Municipal Code), will establish the regulations and procedures for implementing this Plan and update the ordinance to comply with newer requirements under Water Code Chapter 3.3: Excessive Residential Water Use During Drought. A preliminary draft Water Conservation Ordinance is provided in Appendix VI. 1. WATER SUPPLY RELIABILITY ANALYSIS Water supply reliability is the City’s ability to meet the water needs of its customers under varying conditions. Chapter 6 of the City’s Urban Water Management Plan (UWMP) assesses water supply reliability by analyzing the hydrological variability of the City surface water reservoirs (Salinas, Whale Rock, and Nacimiento), regulatory variability, climate conditions, and other factors that may affect the City’s water supplies and customer water uses. The analysis applies worst-case drought conditions according to guidelines set forth in the UWMP plan documentation. The following tables provide data on the reliability of the City’s water supply during normal, single-dry, and a severe drought period lasting five consecutive years. The City remains confident in the reliability of its multi-source water supply portfolio. Table 1 lists the years which correlate to the guidelines for the specific water year type and are based on rainfall information. The City’s average water year was determined to be 2020 based on review and update of the City’s average rainfall total. The City’s single dry water year was determined to be 2013 as the rainfall total that year was the lowest on record. The City’s multiple dry year scenario was determined to be 2011 to 2015 as the combined rainfall total for those five years was the lowest on record. Table 2, Table 3, and Table 4 summarize the City’s water supplies in a normal year, single dry year and a multiple dry year scenario. To address Water Code Section 10635 (b), Table 5 includes available water supply and demand estimate for 2021 through 2025. These water demand projections were derived using 117 gpcd and population growth levels identified in the City’s General Plan Land Use Element. Both factors are higher than current gpcd and the current population. The City does not anticipate a water shortage necessitating any water supply augmentation or requiring water use restrictions if the City entered five consecutive years of drought. The California Department of Water Resources defines drought as: “A deficiency of precipitation over an extended period of time resulting in a water shortage for some activity, group, or environmental sector.” TABLE 1: Basis of Water Year Data Year Type Base Year(s) Volume Available Average Year 2020 10,143 Single-Dry Year 2013 10,143 Consecutive-Dry Years, 1st year 2011 10,143 Consecutive -Dry Years, 2nd year 2012 10,143 Consecutive -Dry Years, 3rd year 2013 10,143 Consecutive -Dry Years, 4th year 2014 10,143 Consecutive -Dry Years, 5th year 2015 10,143 NOTES 1.

Page 367 of 422 2020 Water Shortage Contingency Plan WSCP-4 2. ANNUAL WATER SHORTAGE ASSESSMENT Consistent with the requirements of the 2020 UWMP, the City will perform a water shortage assessment each year to review available water supplies and confirm its approach for the coming year. The degree of the water supply shortage determines the necessary level of response from the City and customers, if any. This water shortage assessment includes evaluation of the following: a. Current year water demand across customer categories (residential, the “CII” sector which includes commercial, industrial, institutional uses, and irrigation) b. Water availability at each water supply source c. Available supplemental water supply options d. Infrastructure considerations, including planned maintenance, repairs, and upgrades The City utilizes a Water Projection Model to test both hypothetical and actual water demand scenarios and to forecast how long water supplies will sustain the community under specific conditions. The Water Projection Model accounts for the storage in the City’s surface water reservoirs, in conjunction with other available resources (i.e., groundwater and recycled water), needed to meet the City’s water demand. The model uses historical hydrologic information (rainfall, evaporation, inflow) based on the average for the worst drought period (2012 to 2014). Other data included in the model is: a. Water entitlement b. Current reservoir levels/storage c. Average gallons per capita per day community water demand d. Rainfall e. Temperature f. Evaporation g. Existing population h. Population growth Utilizing the Water Projection Model as part of its water supply management, the City can foresee whether a water supply shortage is anticipated in any given year, and the severity of a shortage based on the availability of the City’s different sources of supply and water demand trends. The City uses the model to study the potential impacts of various intensities of drought conditions, including increased temperature and evaporation rates, along with decreased precipitation. In accordance with 2018 UWMP requirements, each year the City will prepare a water supply and demand assessment, present it to the City Council for review, and submit its annual Water Shortage Assessment Report to DWR. The Assessment will be conducted based on the use of the City’s Water Projection Model and the key data inputs described above to characterize near-term water supply conditions (i.e., for the next 12 months). Using the Water Projection Model described above for 2021, the City has more than ten years of water available under current water supply and demand conditions. 3. WATER SHORTAGE RESPONSE The City’s water shortage response is dependent on the ability to temporarily augment supply and/or reduce water demand. The City’s water shortage response would combine a variety of strategies including outreach, indoor water efficiency regulations, and outdoor irrigation restrictions, each increasing in intensity as the shortage persists and the City’s water supplies are further restricted. Implementation of these restrictions is necessary to conserve the City’s water supply for the greatest public benefit regarding domestic use, sanitation, and fire protection. This section describes the general strategies the City will employ to mitigate the impacts of water shortage on the community.

The City may provide water conservation tips and suggestions through various public outreach methods, encourage and distribute conservation devices such as low flow shower heads and faucet aerators, discourage excessive outdoor watering, and encourage landscaping with drought tolerant plants. Voluntary reductions measures are described in more detail in Section 4. Mandatory Reduction Measures The City may place mandatory reduction measures on certain uses, such as restricting outdoor watering to prescribed times and number of days per week beginning in the Warning Stage, with days and times for landscape watering further limited in later stages of the plan. Mandatory reduction measures may limit specific inefficient methods of irrigation (i.e., overhead spray/sprinkler ban). The seasonal increase in water demand underscores the importance of implementing outdoor irrigationǦ focused reduction programs. Approximately 50 percent of residential water use in San Luis Obispo is for landscape irrigation. Therefore, restrictions on outdoor water use are generally effective in reducing water demand. Many outdoor uses are considered discretionary, or nonessential for health and safety purposes, are highly visible and relatively easy to monitor, and often are a substantial component of water demand, particularly during the summer months when drought conditions are often most severe. Water Use Prohibitions Water use prohibitions will vary by drought stage, with the fundamental purpose of restricting or prohibiting nonǦessential uses that are not required for basic health and safety. During a declared water shortage, specific prohibitions would be described in a Water Shortage Ordinance adopted by the City Council. In the Critical Stage, all nonǦessential outdoor water use, except recycled water or grey water, may be prohibited. The City will adopt regulations at the appropriate water shortage stage to promote water conservation, such as posting signage at various establishments, offering water audits to maximize water conservation, and prescribing to customerǦspecific water budgets (i.e., water allocations). Supplemental Water Supply Options During a declared water shortage emergency, the City may also utilize supplemental water supply options, or acquire a new supply as warranted by the current situation. This may include utilizing more groundwater and/or expanding the City’s use of recycled water. These water supply options may be less desirable during normal operations due to increased operational costs. 4. WATER SHORTAGE STAGES The goals of the WSCP are to extend the City’s available water resources long enough to gain another winter rainfall period which could serve to add to reservoir storage. Extending available water resources through water demand reduction provides time for the City to bring on supplemental water supplies to meet demand. It is the City’s goal to implement water demand reduction programs that will achieve measurable water savings without requiring customers to make significant lifestyle changes. In the more advanced water shortage stages lifestyle and water-use habit changes will be necessary. This section identifies the measures that may be taken at each stage to achieve desired water use reduction levels. The purpose of establishing water shortage stages is to clearly define the severity of the shortage and establish appropriate targets for demand reductions. Defining these stages allows the City to respond to worsening conditions, with each stage “triggering” different actions. The multiǦstage approach provides different levels of response for a water shortage event ranging from a ten percent supply deficiency up to a 50 percent or greater deficiency. Table 7 provides a quick reference guide to the WSCP, though City Council may adopt variations of these Water Shortage Response Actions, independent from the stage resulting from the use of the Water Projection Model, to strategically address the current water shortage situation. Each stage describes increasing levels of water demand reduction and water supply augmentation methods. As stated previously, during an actual water shortage emergency, other measures may be imposed. The City Council would formally declare a water shortage emergency, per Water Code Chapter 3. Page 369 of 422 2020 Water Shortage Contingency Plan WSCP-6 TABLE 7: Water Shortage Response Stages Quick Reference Guide STAGE WATER SUPPLY STATUS1 CITY ACTIONS Monitor 5+ years of available water supply City maintains existing water conservation staffing levels and budget that supports meeting internal water efficiency goals and regulatory requirements for water conservation, including ongoing public outreach. Watch < 5 years of available water supply (up to 10% water shortage) City increases programs that encourage voluntary water conservation including public outreach, rebate programs, and water efficient fixture giveaways. City examines available alternative water sources (groundwater expansion, recycled water filling stations, water purchase agreements, etc.), City modifies internal operations to focus on decreasing water loss and prepares for subsequent WSCP stages. City ceases any short-term outside- City water sales/leases. Warning < 4.5 years of available water supply (up to 20% water shortage) City implements time of use irrigation restrictions (7:00 PM – 7:00 AM). City increases staffing, budget, and outreach to achieve additional voluntary conservation savings while preparing for Alert-Critical stages. Alert < 4 years of available water supply (up to 30% water shortage) City requires mandatory conservation measures including outdoor irrigation restrictions (four day a week watering) and considers a Water Offset Program for new connections. Severe < 3.5 years of available water supply (up to 40% water shortage) City implements Water Allotment Program. Water Offset Program for new connections may be increased (1.5:1 or 2:1 offset ratio). Allowable irrigation reduced to three days per week. Extreme < 3 years of available water supply (up to 50% water shortage) City continues to implement a Water Allotment Program with reduced allotment levels. Water Offset Program for new connections may be increased (1.5:1 or 2:1 offset ratio). Allowable irrigation reduced to two days per week with optional additional measures limiting turf and spray irrigation. Critical < 2.5 year of available water supply (>50% water shortage) City continues to implement a Water Allotment Program at further reduced levels (minimum for public health and safety). Irrigation no longer permitted. Water Offset Program to cease and no new connections permitted. NOTE: The City’s Water Supply Status is informed by the Water Projection Model described in Section 2, Annual Water Shortage Assessment, of this WSCP. Page 370 of 422 2020 Water Shortage Contingency Plan WSCP-7 Water Shortage Response Stage: MONITOR The City of San Luis Obispo has made water conservation an integral part of the community’s culture and policy context for managing its water resources. The community has demonstrated a high commitment to reducing its water usage during water shortages. Although not an actual declaration of a water shortage, the Water Shortage Contingency Plan’s Monitor Stage remains in place at all times along with voluntary conservation. This stage is focused on achieving voluntary water savings, as opposed to a mandatory demand reduction programs. To ensure the City is using water responsibly and remaining in compliance with water efficiency goals are regulations, the City continually assesses available water supply levels, monitors customer water demand trends, conducts water loss audits, and evaluates potential supplemental supply projects. The following are examples of demand management measures that may be taken to maintain water use efficiency goals: 1. Implement public outreach and communication programs (bill stuffers, social media, etc.) 2. Participate in trade shows, home shows, and special community events 3. Offer complimentary water audits 4. Identify and notify customers of possible leaks and inefficient uses of water 5. Encourage the use of drip irrigation and drought tolerant plants 6. Implement school (K-12) education programs related to water conservation 7. Enforce the water efficiency retrofit program (toilet retrofit upon sale program) Actions at the Monitor Stage would also include active enforcement of the City’s water waste prohibitions, such as those from Chapter 13.07 of the City’s Municipal Code, which defines water waste as follow: City of San Luis Obispo, Municipal Code 13.07.020 – Water runoff prohibited. A. No person shall cause any water delivered by the city water system to flow away from property owned, occupied or controlled by such person in any gutter, ditch or in any other manner over the surface of the ground, so as to constitute water waste runoff. B. “Water waste runoff” means water flowing away from property and which is caused by excessive application(s) of water beyond reasonable or practical flow rates, water volumes or duration of application. (Ord. 1089 § 1 (part), 1987) Page 371 of 422 2020 Water Shortage Contingency Plan WSCP-8 Water Shortage Response Stage: WATCH When the City’s available water supply would provide less than five years of water, staff could recommend to the City Council that they adopt a resolution declaring a water shortage and to enter the Watch Stage and urge the public to reduce water use by approximately ten percent. During the Watch Stage, the demand management measures utilized during the Monitor Stage above will increase along with a continued focus on voluntary water use reduction. The City will also increase public outreach, implement system and operational changes, increase enforcement actions and patrols, and undertake other administrative actions. These program expansion and changes may include: 1. Water Demand Reduction Programs: A. Accelerate water audit programs for all customer classes B. Identify largest water users in each sector and contact for complementary water audits C. Increase water waste patrols D. Conduct water use surveys E. Implement rebate programs F. Consider the use of irrigation limitations G. Host workshops on effective irrigation practices 2. Public Outreach Programs: A. Issue a press release following Watch Stage declaration B. Include information in quarterly Resource Newsletter C. Evaluate outreach effectiveness and expand outreach for non-English languages as needed D. Update City website and create a page dedicated to information on details of WSCP Watch Stage E. Use billing inserts to notify public of current situation and needs F. Coordinate with regional partners on messaging and outreach G. Increase outreach to Cuesta and Cal Poly students and at public events such as Farmers Market, SLO Home Show, homeowners association board meetings, meetings with hospitality industry, etc. H. Focus social media platforms on issues consistent with needed demand reductions 3. System and Operational Changes: A. Cease any short-term water sales. B. Reduce water usage for water main flushing and hydrant flushing C. Reduce distribution system pressure where feasible D. Increase leak detection, water meter testing, and water meter replacement E. Require use of non-potable water sources for all street sweeping and hydrocleaning F. Activate the Drought Taskforce 4. Enforcement Actions: A. First Violation: Customer Notification and Education Staff will notify the customer of the particular violation observed, and the demand reduction programs currently in place. Staff will assist the customer in determining resources necessary to comply with requirements. Examples of notification include: door tags containing educational information, mailed letter, and/or personal phone call by staff. B. Second Violation: Issuance of Notice of Violation Customer will be issued a written notice of violation (NOV), notifying the customer of specific violation, date and time the violation was observed, and consequences of subsequent violations. Page 372 of 422 2020 Water Shortage Contingency Plan WSCP-9 C. Subsequent Violations: Customer may be issued a penalty/fine for violation. 5. Other Administrative Actions: A. Begin drafting ordinance revisions and code changes that would go into effect in subsequent water shortage stages. B. Plan for the funding and implementation of specific conservation programs launched in subsequent water shortage stages. C. Review potential fiscal impacts of drought (i.e., increased water supply, operational, and capital costs); and demand reductions (reduced revenue). D. Identify and plan for the need for additional staff. In planning for additional staff, consideration should be given to funding, available office space, vehicles, training, and other needed supplies and support. E. Consider need for drought surcharge to stabilize revenue. F. Consider deferring previously scheduled capital projects as necessary to invest in acquisition of needed water supply sources and demand reductions. G. Review available supplemental water supply options, such as increased use of groundwater, utilization of potable reuse, and implementation of residential recycled water filling stations for landscape irrigation. Water Shortage Response Stage: WARNING When the City’s available water supply would provide less than 4.5 years of water, staff could recommend to the City Council that they adopt a resolution to enter the Warning Stage and urge the public to reduce water use by an additional 10 percent including mandatory conservation measures. The water conservation measures described in the Monitor and Watch Stages above may increase during the Warning Stage, with an increased focus on limiting outdoor water uses. System and operational changes would remain in place. These increases and additions to programs may include: 1. Water Demand Reduction Programs: A. Continue implementation of and possible increase of all demand reduction programs listed in Watch Stage. B. Limit outdoor watering to between the hours of 7:00 PM and 7:00 AM. C. Require restaurants to only serve water upon request. D. Restrict use of decorative water features and fountains. 2. Public Outreach Programs: A. Continue implementation of and possible increase of all public outreach programs listed in Watch Stage. B. Issue a press release following Warning Stage declaration. C. Target outreach to customers with large landscapes regarding irrigation restrictions. D. Use of billing inserts, social media, postcards, and direct mail pieces to inform customers of new requirements and prohibitions. E. Coordinate with local business groups such as the Chamber of Commerce and landscaping associations to help encourage conservation among commercial customers. F. Coordinate with homeowners associations, property rental agencies, and other local groups to help encourage conservation among residential customers. 3. Enforcement Actions (Same as previous stage) Page 373 of 422 2020 Water Shortage Contingency Plan WSCP-10 4. Other Administrative Actions: A. Continue implementation of and possible increase of all other administrative actions listed in Watch Stage. B. Begin preparing for the Alert Stage. 5. Optional Implementation of a Water Demand Offset Program: During the Warning Stage, staff will begin updating the Water Demand Offset Program and messaging about the program to the development community. The City may consider implementing a water demand offset program during this stage. Water demand offset programs are designed to require new development that causes increased water demand to offset such demand through conservation or acquisition/development of new water supplies. The goal of an offset program is to ensure that new development does not increase current water demands. It should be noted that offset programs simply expedite water efficiency measures and thus create water savings in the short term. Depending on the nature of the offset, long-term savings may not be realized. At the Warning Stage the City may choose to implement a “net neutral” offset program, requiring that new demands offset usage at a rate of 1:1. Future stages of the WSCP may suggest a more aggressive, “net positive” water demand offset program. A “net positive” water demand offset program would require a positive offset of a project’s water demand. An example of this would be a project required to offset its water demand at a ratio higher than 1:1, such as 2:1 or 3:1. There are several types of offset programs in use across California and the United States. Examples of potential offset programs are listed below. A. Toilet replacements B. Smart irrigation controllers C. Submetering D. In-lieu fees (fees are used to support new water supply projects) E. Irrigation system retrofits F. Waterless urinals G. Rainwater capture H. Recycled Water Retrofit Projects Water Shortage Response Stage: ALERT When the City’s available water supply would provide less than four years of water, staff could recommend to the City Council that they adopt a resolution to enter the Alert Stage and urge the public to reduce water use by an additional 10 percent including mandatory conservation measures. The water conservation measures described in the stages above may increase during the Alert Stage, with an increased focus on limiting outdoor water uses. System and operational changes would remain in place. These increases and additions to programs may include: 1. Water Demand Reduction Programs: A. Limit outdoor watering to four days a week and only between the hours of 7:00 PM and 7:00 AM. B. Defer landscape installations for new development or require development to install landscaping that provides a 50 percent reduction in Maximum Applied Water Allowance (MAWA). This would not apply to sites irrigated with recycled water. Page 374 of 422 2020 Water Shortage Contingency Plan WSCP-11 2. Public Outreach Programs: A. Continue implementation of and possible increase of all public outreach programs listed in previous stages. B. Issue a press release following Alert Stage declaration C. Utilize water use allocation software to identify inefficient water users and make direct contact with these properties. 3. Enforcement Actions (Same as previous stage) 4. Other Administrative Actions: A. Continue implementation of and possible increase of all other administrative actions listed in prior stages. B. Prepare utility billing system and bill format for water allocations and reductions listed in subsequent stages. C. Establish appeals committee for customers who exceed allotments in subsequent stages, request health and safety variances, or receive fines from violating water waste prohibitions. D. Increase utility billing training and support to address additional requirements of future stages. E. Begin preparing for Severe Stage. Implementation of a Water Demand Offset Program: At the Alert Stage the City may implement a “net neutral” offset program or increase a previously approved program to a “net positive” program (ex: 1.5:1 or 2:1 offset ratio). Future stages of the WSCP may suggest a more aggressive, “net positive” water demand offset program. Water Shortage Response Stage: SEVERE When the City’s available water supply would provide less than 3.5 years of water, staff could recommend to the City Council that they adopt a resolution to enter the Severe Stage and urge the public to reduce water use by an additional approximately 10 percent. At this water shortage response stage, the City would continue implementation of demand reduction measures, public outreach, enforcement, and other responses and programs described in prior stages. System and operational changes would remain in place. At the Severe Stage, a water offset program may increase to a “net positive” program, such as 1.5:1 or 2:1 ratio. Previous Water Demand Reduction Programs should be increased to include: x Limit outdoor watering to three days a week and only between the hours of 7:00 PM and 7:00 AM. During the Severe, Extreme, and Critical stages of the WSCP the City may adopt a Water Allotment Program, restricting the water use on an account-by-account basis. The following allotment method may be used: Customer Classification Severe Stage Allotment Single-family Residential and Multi-family Residential A per capita allotment allowing for indoor use and a minimal outdoor irrigation budget. Verification of persons per household may be requested Commercial and Institutional Baseline allocation or allocation based on percent reduction from normal usage Landscape Meters Allocation based on percent reduction from normal usage Page 375 of 422 2020 Water Shortage Contingency Plan WSCP-12 Water Shortage Response Stage: EXTREME When the City’s available water supply would provide less than three years of water, staff could recommend to the City Council that they adopt a resolution to enter the Extreme Stage and urge the public to reduce water use by an additional 10 percent. At this water shortage response stage, the City would continue implementation of demand reduction measures, public outreach, enforcement, and other responses and programs described in prior stages. System and operational changes would remain in place. At the Severe Stage, a water offset program may increase to a “net positive” program, such as 1.5:1 or 2:1 ratio. Previous Water Demand Reduction Programs should be increased to include: x Limit outdoor watering to two days a week and only between the hours of 7:00 PM and 7:00 AM. x Optional implementation of additional restrictions on turf and/or spray irrigation. Customer Classification Extreme Stage Allotment Single-family Residential and Multi-family Residential A per capita allotment allowing for indoor use and a reduced outdoor irrigation budget versus the Severe Stage. Verification of persons per household may be requested Commercial and Institutional Reduced baseline allocation or allocation based on percent reduction from normal usage Landscape Meters Reduced allocation based on percent reduction from normal usage At this stage, due to the limited water supplies that remain, the City could consider removal of the “courtesy notification.” Water Shortage Response Stage: CRITICAL When the City’s available water supply would provide less than 2.5 years of water, staff could recommend to the City Council that they adopt a resolution to enter the Critical Stage and urge the public to reduce water use by an additional approximately 10 percent. At this water shortage response stage, the City would continue implementation of demand reduction measures, public outreach, enforcement, and other responses and programs described in prior stages. System and operational changes would remain in place. Due to the limited water supplies that remain, the City would consider the cessation of new connections to the City’s water system. Previous Water Demand Reduction Programs should be increased to include: x Cessation of irrigation for all customers, minus specific exemptions. Customer Classification Critical Stage Allotment Single-family Residential and Multi-family Residential A per capita allotment allowing for indoor water use. Irrigation not permitted. Verification of persons per household may be requested Commercial and Institutional Reduced baseline allocation or allocation based on percent reduction from normal usage. Irrigation not permitted. Landscape Meters Not permitted. Page 376 of 422 2020 Water Shortage Contingency Plan WSCP-13 5. AERIAL IMAGERY BASED WATER BUDGETS In 2021, the City is investigating the use of software that would allow for aerial imagery to be used to establish parcel-by-parcel water budgets during the Severe, Extreme, and Critical stages of the WSCP. This software utilizes aerial imagery to identify the irrigated, irrigable, and non-irrigable square footage of every parcel within the City’s water service area. These measurements can then be used to establish an outdoor irrigation budget for each property. If the City invests in this technology, day per week irrigation restrictions outlined in the WSCP may be replaced by property-specific outdoor irrigation efficiency goals, requiring that property owners meet increasing efficiency measures at progressive stages of the WSCP. Additionally, many of these aerial imagery software packages allow for indoor water use budgets to be established, generally based on the number of residents living within a home, much like the City’s water allocation program identified within the WSCP. The use of this technology in establishing water budgets would require an update to the City’s WSCP prior to implementation. 6. EXEMPTIONS AND APPEALS As the community was impacted by the 2011-2015 drought and irrigation restrictions were put into place, community members advocated for certain exemptions related to water use restrictions. The following series of exemptions will help ensure the health and well-being of the community while not making a substantial impact on available water supplies1 . Sites using Recycled Water for Irrigation Sites utilizing recycled water are exempt from irrigation restrictions due to their reliance on recycled water in place of potable water. These sites include major City parks, such as Damon Garcia Park, French Park, Islay Park, Laguna Lake Park, Laguna Hills Park, De Vaul Park, the Laguna Lake Golf Course, and Laguna Middle School, as well as many multifamily and commercial properties. Irrigation Exceptions at Specific Facilities During the recent drought City staff and community members provided feedback that City parks with inadequate irrigation allotments could lead to hazardous conditions at recreation and play environments. To address these concerns, and to provide communal spaces for recreation during times when many homes allowed landscapes to die, in 2016 the City Council approved an amendment to Chapter 13.07.030 of the Municipal Code, allowing for daily irrigation at designated City facilities during turf renovation, and three times per week thereafter. This exemption is recommended to be expanded to include schools within the City’s boundaries as they are used for recreation in a similar manner to City parks. This exemption would only go into place in stages of the WSCP requiring irrigation restrictions. Irrigation of Trees During the 2011-2015 drought, the City heard from many residents who opted to cease irrigation of their trees in order to reduce their water demand. Unlike turf, shrubs, and other groundcover, trees take a great amount of time to grow and provide substantial ecological, environmental, practical, and economic value to the community. An exemption to irrigation restrictions allowing for the use of a hose and shutoff nozzle to hand water trees will allow the community to preserve this precious multi-benefit resource. Hospitals, Healthcare Facilities, and other Specific Business Types Hospitals, healthcare facilities, and other businesses requiring water for the health and safety of at-risk people may apply for an exemption on a case by case-basis. This exemption may be granted at the discretion of the Utilities Director or his/her/their designee. Appeals Appeals related to water use restrictions within the WSCP and associated penalties may be appealed to the Utilities Director or his/her/their designee. 1 The City does not supply potable water to separately metered water features, such as ponds, lakes, waterfalls, and fountains. Page 377 of 422 2020 Water Shortage Contingency Plan WSCP-14 7. REVENUE AND EXPENDITURE IMPACTS During a water shortage, revenues from water sales can be reduced but the City’s operations and maintenance costs would not reduce accordingly. In fact, during these periods, the City’s operational and staffing budgets can increase due to the implementation of water demand reduction measures, public outreach, increased enforcement, groundwater exploration, and other actions taken by the City during the shortage. The reduction in revenues resulting from decreased water use may also result in the need to raise water rates during that period. Under the City’s existing water rate structure (updated in 2018), water rates include both a base fee and volumetric charge based on customer usage and resulting demand on the water system. To minimize the need to raise rates during water shortages, the City has a policy that requires a minimum reserve of twenty percent of the Water Fund’s operating budget. The City also maintains a rate stabilization fund which is ten percent of rate revenue. This rate stabilization fund is designed to help stabilize rate increases and could be used to achieve this purpose of costs went up during a water shortage. City staff provides ongoing tracking of revenues and evaluates the potential impacts associated with changes in water demand assumptions used in the Water Fund Analysis. The City Council considers the water rates necessary to provide water service to the community on an annual basis and must approve water rate increases in order for them to become effective. In addition to securing water supplies, Water Fund revenue supports ongoing maintenance and operating programs needed to ensure that the water treatment and delivery systems meet all federal and state water treatment regulations and are operated and maintained to provide safe and reliable service. During the 2012-2015 drought, the City utilized a drought surcharge to help with revenue shortfalls that occurred due to the State of California’s mandatory conservation measures. This drought surcharge was subject to Proposition 218 and expired upon the end of the State of Emergency related to the drought. The adoption of a temporary drought surcharge remains an option for meeting future drought-related revenue shortfalls. 8. MONITORING, REPORTING, AND REFINEMENT PROCEDURES The City reads water meters monthly to ensure water consumption data is collected for tracking, analysis, and to meet state reporting requirements. Monitoring and reporting key water use metrics is fundamental to water supply planning and management. Monitoring is also essential to ensure that the response actions are achieving their intended water use reduction purposes, or if new actions need to be considered. Compliance tracking is also necessary for an effective enforcement program. To evaluate the functionality of the WSCP and ensure strategies are effective, staff will monitor community response to water demand reduction measures, public outreach, enforcement, and other administrative actions at each water shortage response stage. This will include review of monthly water consumption data for each customer class and monitoring associated revenue and expenditure impacts. Staff will make recommendations on program refinements to the City Council with water shortage stage progression. 9. CATASTROPHIC WATER SUPPLY INTERRUPTION The City’s Local Hazard Mitigation Plan (LHMP) was completed in 2019 as part of a countywide effort. The LHMP was adopted by the City Council in 2020. This work included risk assessment related to seismic risk (earthquakes, faults, and liquefaction). The LHMP will be submitted with the 2020 UWMP to satisfy the requirements of CWC Section 10632.5. The City has an Emergency Response Plan (ERP) to cover a variety of potential disasters including earthquakes, floods, wildland fires, etc. The ERP identifies resources available to the City from other agencies or private companies in the area. Additionally, the City of Morro Bay and the Whale Rock Commission (of which the City of San Luis Obispo is a member) executed an agreement in June of 2000 which provides for Mutual Aid between the agencies during disruption of water deliveries or lack of available water supplies. The agreement provides a general framework for exchanging water between agencies in the event of emergencies or other water disruptions. The agreement is voluntary based on each agency’s ability to assist at any point in the future. Page 378 of 422 2020 Water Shortage Contingency Plan WSCP-15 In relation to providing water service, the City would utilize both on-site and portable generators to minimize water disruptions during an extended power outage. These generators are available to the City at any time and actively maintained to ensure they are functioning adequately. The City is a member of the Water Agency Response Network (WARN). WARN is a statewide organization of water agencies and companies that have entered into a mutual aid agreement to assist other water agencies during emergencies or other water related situations. The agreement provides the framework for providing assistance and provides a key contact to initiate a multiple agency response to a water emergency situation. 10.
