CONSENT
ITEM NUMBER: 8.

TITLE
4th Quarter Investment Report for the City and Fire District

RECOMMENDATION
Receive and file the City and Fire District’s Treasurer’s Report for the month ended June 30, 2022.

CONTACT
Jemelyn Cruz, Interim Finance Director

BACKGROUND & ANALYSIS
The City’s Investment Policy requires; the Treasurer to submit a quarterly investment report to the City Council. The report(A5achment 1) for the quarter ended June 30,2022 includes investment transac8ons for both the City and Fire District. The report shows the City’s cash and investment book balance, including debt reserves and unspent proceeds, was $73,972,521. The Fire District’s book balance was $6,865,876.

The City’s diversified porBolio includes $45.03 million invested in the California State Treasurer’s Office Local Agency Investment Fund (LAIF) and $23.89 million managed by Chandler Asset Management. The funds managed by Chandler are invested in U.S. Treasury Notes, Federal Agency Securities, Asset Backed Securities, U.S. Corporate Notes, Supranational Securi8es, and FDIC insured Corporate Notes. The lower market value to book value is due to the rising interest rate environment. That is an unrealized number, since the City normally holds investments to maturity. The increasing rate environment also offers an opportunity to invest to achieve higher returns.

The Fire District maintains cash and investment accounts separately from the City. The book value of the District’s total porBolio is $6.86 million. All cash not needed to meet the current opera8onal requirements of the Fire District is invested with Local Agency Investment Fund (LAIF).

COUNCIL PRIORITY PROGRAMS AND PROJECTS

TITLE
Property Exchange with Napa Valley Unified School District

RECOMMENDATION
Adopt a Resolu,on approving a Property Exchange and Acquisi,on Agreement to transfer approximately 5.6 acres of land where the community center/gymnasium is located to the Napa Valley Unified School District in exchange for receiving the 6.57-acre property where the former Napa Junc,on Elementary School is located (on Napa Junc,on Rd.) from the Napa Valley Unified School District.

CONTACT
Jason Holley, City Manager

BACKGROUND & ANALYSIS
Executive Summary
On August 22, the City Council approved the Property Exchange and Acquisi,on Agreement. The Agreement is revised to remove provision for a due diligence period and to require a reconcilia,on of the amount of school fees paid at building permit issuance. Staff recommends the Council approve the updated Agreement.

Background
The City of American Canyon and the Napa Valley Unified School District (NVUSD) are the two largest landowners in American Canyon. As the City’s popula,on grew from 6,200 people at incorpora,on in 1992 to nearly 22,000 people today, the City worked with the NVUSD to expand educa,onal opportuni,es here. Twenty-five years ago, this unique partnership manifested itself in the crea,on of a joint civic complex that includes the American Canyon Middle School (ACMS), a community center/gymnasium and the Philip West Aquatics Center (PWAC).

Tonight, the Council will discuss the par,es' inten,on to collaborate on the future of school and civic sites within American Canyon. The discussions pertain to various proper,es, including the site of the former Napa Junc,on Elementary School (located on Napa Junc,on Road), the community center/gymnasium at ACMS, and vacant lands on Eucalyptus Drive and American Canyon Road. Key components of the new partnership include the City relinquishing its role as the co-owner of the community center/gymnasium and NVUSD transi,oning its ownership of the former Napa Junc,on 362
Elementary school site to the City. The City and NVUSD intend upon accomplishing this exchange by through a "Property Exchange and Acquisition Agreement" (Attachment 2, Exhibit A).

Importantly, the City and NVUSD are commiEed to ensuring exis,ng civic facili,es will remain available for use by the community through the City’s and NVUSD’s respec,ve facility rental programs. As noted in a recent joint press release, NVUSD Superintendent Dr. Rosanna MuceF states, “It is our duty and responsibility to provide the best educa,onal programs for students across the district, and this exchange will allow us flexibility for enhanced programs for American Canyon students. At the same ,me, our collec,ve hope with the City is to maximize the space for the broader community – so we believe this exchange will represent a ‘win-win’ for everyone.” Meanwhile City Manager Holley added, “The future of the former school site is a ‘blank slate’ and aMer an agreement is finalized, the City Council will begin its process for listening to the community’s ideas and interests before ul,mately deciding its new future. The con,nued sharing of our respec,ve civic facili,es and maximizing their use remains essen,al for the community's benefit.

The City appreciates our collaborative relationship with NVUSD and values our partnership”. 100 Benton Way Property
The City currently owns a 9.66 acre-property (APN 058-040-026) located at 100 Benton Way, which is used for educa,on and community recrea,on purposes. The "L-shaped" property was dedicated by a developer to the former American Canyon County Water District in 1986, and it became a City asset at Incorporation in 1992 (Attachment 2, Agreement Exhibit A).

The "100 Benton Way Property" contains the community center/gymnasium, a por,on of the ACMS track and field, a temporary skateboard park, and the PWAC. Per "1997 Agreements" (Attachment 3), the NVUSD is a "tenant" of the City for the first 20-years and then star,ng July 1, 2022, the NVUSD and the City are to become "co-owners" of the gymnasium/community center. Additionally, each party retains separate sole ownership of the ACMS and PWAC respectively.

Unfortunately, the 1997 Agreements are rela,vely silent as to details of the future transi,on from landlord-tenant rela,onship to one of co-ownership. Of note, the NVUSD is not a tenant nor do they "co-own" any other educa,onal facili,es districtwide. Suffice it to say, standards for educa,onal facili,es and the general public are different. Prospec,vely this juxtaposi,on is likely resolve in favor of the most conservative conditions.

For example, the ACMS track/field straddles the ACMS Property and 100 Benton Way Property. The maintenance standards for this facility are not severable based upon separate ownership and must meet the more strict CA Department of Educa,on (Cal-Ed) and NVUSD requirements. Under a coownership scenario, the City may have to pay for a por,on (if not all) of any needed repairs, even though it rarely uses the facility. Likewise, this concept holds true for the gymnasium/community center itself - a 20-year old building approaching significant lifecycle maintenance costs (e.g. roof replacement, etc.) Lastly, aMer discussing future co-ownership issues with the "NVUSD 2x2 CommiEee" (Joseph/Washington), it also became clear changes to allowable uses at the building 363
were imminent. In par,cular, consistent with State Law (California Business and Professions Code Sec,on 25608) and NVUSD policy, the use of alcohol would be prohibited at the community center/gymnasium.

Under the proposed agreement, the City would relinquish its (impending) co-ownership of a 5.6- acre por,on of the 100 Benton Way Property through the execu,on of a Quitclaim Deed (dashed area shown on AEachment 2, Agreement Exhibit B). The community center/gymnasium, a por,on of the ACMS track and field, a temporary skateboard park are all located on the por,on of land to be transferred to NVUSD. The PWAC would stay under City ownership on a new (smaller) parcel.

Prospec,vely, the gymnasium will be available for City and community use consistent with the NVUSD policies and facility rental program. Addi,onally, the temporary skateboard park will be relocated to a loca,on that is s,ll TBD. Lastly, the northern (rear) of the property will be secured in the same manner as the northern boundary of the ACMS property to prevent unauthorized access and thus, pedestrians will no longer access the property from the north.

Former Napa Junction Elementary School Property
NVSUD owns a 6.57-acre property (APN 058-320-0015) which is the site of the (former) Napa Junc,on Elementary School (“Napa Junc,on Rd. Property”). Napa Junc,on Elementary was moved from its former loca,on due to the damage from the 2014 earthquake and recently opened a brandnew campus on Eucalyptus Drive. The City's acquisi,on of the Napa Junc,on Rd. Property is for public community and recrea,on purposes and to con,nue vehicle access for Napa Junc,on Road.

The property abuts the 7-acre LiEle League Field - which came under City ownership in conjunc,on with the 1997 Agreement and is an example of the prior land exchange. All told, the City would own

13.5-acres of land bounded by Napa Junc,on Rd. and Hess Road (on 2 sides) (AEachment 2, Agreement Exhibit C). While the exis,ng buildings can be re-used, development of new buildings will be constrained by the presence of earthquake faults. Unoccupied facili,es such as new parks, ballfields, parking lots and unoccupied structures would not be constrained.

In the near term, the City intends to develop a full-,me opera,onal presence on a por,on of the now vacant property to prevent vandalism, etc. Addi,onally, the mul,-purpose room (with kitchen) and classrooms are intended to be made available for public through the City's facility rental program. Long-term, the property is a blank slate. Strategically located next to the City-owned LiEle League Field and underdeveloped property to the east, there are numerous opportuni,es for public serving amenities.

General Plan Conformity
Consistent with California Government Code Sec,on 65402, on May 26, the Planning Commission unanimously confirmed the proposed exchange of public proper,es conforms with the City's General Plan (AEachment 4). Of note, the Commission determined the City's co-ownership interests in a por,on of the "100 Benton Way Property" containing the community center/gymnasium et al. to be exchanged to the District will be unnecessary for the City as it will be gaining the Napa 364
Junc,on Rd. Property from the District intended for community and recrea,on purposes and to con,nue vehicle access to implement, consistent with Government Code Sec,on 65103(b) its General Plan, 2018 Circula,on Element (Pps. 11, 13), designa,ng Napa Junc,on Road as a minor and major collector.

General Plan Update - Land Use Element
The City is currently processing a comprehensive update to its General Plan, including the Land-Use Element. On May 5 and June 7, the City Council reviewed the General Plan Update DraM Environmental Impact Report (DEIR) No,ce of Prepara,on (NOP), which included poten,al changes to the Land-Use Element (AEachment 4). The Agreement provides that City staff will include residen,al land-use designa,ons for certain undeveloped parcels of land adjacent to the (new) Napa Junc,on Elementary School and the American Canyon High School, and these changes are shown in the DEIR NOP. The changes shown in the DEIR NOP will incorporated into the DraM General Plan, which will be available for further review and comment by the public, before considera,on/approval by the Council.

Next Steps
Assuming the Council approves the Agreement tonight, then the NVUSD Board is scheduled to consider items related to this property exchange at an upcoming meeting in August.

On August 4, the Parks and Community Services Commission will consider recommenda,ons to City Council for loca,ons to relocate the skate park, which is scheduled to be brought forward for Council consideration on August 16.

COUNCIL PRIORITY PROGRAMS AND PROJECTS
Community and Sense of Place: "Build on the strength of our local community to develop a clear 'sense of place' and establish our unique identity."

FISCAL IMPACT
Increased Future Costs
The Agreement will result in increased one-,me costs of at least approximately $100k for the reloca,on of the temporary skate park. One-,me costs for renova,ons of the former school property have not been determined and will depend upon future decisions about short-term and long-term uses. Addi,onally, the City's is expected to incur increased on-going costs to for ren,ng the gymnasium. If all of the current recrea,on programing remains at the gymnasium, the cost is es,mated to be $60k; however, staff an,cipates moving some programming to the Napa Junc,on Rd. location to reduce cost.

Avoided Future Costs
The Agreement is expected to contain "as-is" provisions - meaning each party is solely responsible for future maintenance costs, liabili,es, etc. Thus, all future costs to maintain/repair/replace the ACMS track and field, gymnasium etc. up to "educa,on standards" will be borne by the NVUSD. 365
Near-term es,mates of the costs for the ACMS track and field exceed one million dollars. Future costs for the building have not been estimated, but expected to be significant.

ENVIRONMENTAL REVIEW
The Project is exempt under the California Environmental Quality Act (Pub. Res. Code § 21000 et seq., "CEQA") as it is not a "Project" under CEQA Guidelines § 15378(b), and is categorically exempt under CEQA Guidelines § 15312-sale of surplus government property, and statutorily exemp,on under Government Code § 65996: Methods of considering and mi,ga,ng impacts on school facilities.

{SR750989}
2 NOW, THEREFORE, incorporating the foregoing Recitals, the Parties agree as follows:

1. Property Exchange. The Parties shall cooperatively accomplish the following transactions to effectuate the property exchange:
a. The City will convey fee title to the City Exchange Property, including all right, title, and interest to all buildings and improvements located thereon, to the District by grant deed substantially in the form attached as Exhibit “F” hereto (“City Exchange Property Grant Deed”). b. The District will convey fee title to the District Exchange Property, including all right, title, and interest to all buildings and improvements located thereon, to the City by grant deed substantially in the form attached as Exhibit “G” hereto (“District Exchange Property Grant Deed”).

2. Conditions of Property Exchange.
a. Conditions applied to District and City:
i. The Subject Properties will be transferred to the District and the City, respectively, in an “as-is” condition.
ii. The shared ownership/operation of Community Center/ACMS Gym Property by District and City will terminate as described in this Agreement. All past agreements regarding ACMS Gym Property not specifically referenced in this Agreement - including but not limited to - that certain March 20, 1997 Sublease and Joint Use Agreement between the Parties will terminate as of the Closing (as that term is defined in Section 8(b) hereof). iii. Respective “Title(s)” to the Subject Properties shall be "free and clear" of any and all encumbrances before the Closing, including but not limited to removal of any current debt obligations secured by either of the Subject Properties. The intent is for the Subject Properties to be unencumbered at the time of Closing.
iv. The Parties will take all actions reasonably necessary to cause the existing License Agreement ("License Agreement") made and entered into July 23, 2020, by the City and Pacific Gas & Electric Company (“PG&E”) to be replaced and superseded by a new license agreement between the City, the District and PG&E.
v. Promptly after the Closing, the Parties will notify any 3rd-party users of the Subject Properties about change in ownership and termination of use. vi. After Closing, each Party will be responsible for paying the cost of utility services to their respective property.
b. City Obligations.
i. On or prior to the Effective Date, City will cease renting facilities at the City Exchange Property to community groups and other third-party users. In the event that City has scheduled any such rentals, District will honor scheduled rentals through October 30, 2022, as long as those rentals do not conflict or interfere with school activities, events, or athletic programs, which shall have priority use of the facilities for practices and games. Subject to the foregoing, the Parties will cooperate with one another to resolve any issues related to such rentals affecting District use or school activities. City 370
{SR750989}
3 shall take all actions necessary to cancel such rentals scheduled after October 30, 2022. City shall provide District with reasonable documentation evidencing any such cancellations. ii. City will remove the skate park within one-hundred-eighty (180) days of the Agreement Closing Date. District will grant City a temporary right of entry valid for one-hundred-eighty (180) days from the Agreement Closing Date to accomplish removal. District shall have the right in its sole discretion to fence off the skate park area so long as such fencing does not prevent the City from removing the skate park.
iii. As shown on Exhibits B and F-1, the top of the southerly bank of the Rio Del Mar Creek generally represents the boundary between the property to be owned by the District (i.e..

City Exchange Property) and the northern remnant of the Community Center/ACMS Gym Property which is to be retained in ownership by the City after Closing. While the preponderance of Rio Del Mar Creek lies within said northern remnants of property retained in ownership by the City, a portion of the southerly bank of the Rio Del Mar Creek lies within the City Exchange Property, and notwithstanding provisions of this Agreement stipulating each Party is solely responsible for maintenance of only its own property after Closing, the Parties agree the City is solely responsible for maintenance of those portions of Rio Del Mar that lie upon the City Exchange Property (owned by the District). The Parties agree that they will memorialize their specific, separate obligations related to the City’s maintenance responsibility by separate instrument to be recorded within thirty (30) days after Closing. iv. As evidenced by that certain “Notice of Preparation of the City of American Canyon General Plan Update”, dated July 5, 2022 (Exhibit “H”), City has designated the Remnant District Parcels as “Residential” in the Draft General Plan Land Use Element, with residential density similar to the immediately surrounding area
v. City will ensure that all school impact fees required for the Oat Hill Residential Project (“Project”) pursuant to Education Code sections 17620, et seq., and Government Code sections 65995, et seq. (“Fees”), are provided to the District prior to Closing. Fees will be based on the amount of fees approved and adopted by the District’s Board on April 21, 2022, which is $4.79 per square foot of residential development and $0.78 per square foot of commercial development. As of the Effective Date, the Parties anticipate that the Project will include 263,472 square feet of residential development, such that the amount of Fees to be paid at Closing will be One Million Two Hundred Sixty-Two Thousand Thirty Dollars ($1,262,030.00) (“Prepayment Amount”).

At such time as the City intends to issue one or more building permits for the Project (or any portion thereof), City shall first require the Project developer or his or her successor-ininterest or assignee (“Developer”) to obtain certification from the District, as required by Education Code section 17620(b), and provide same to the City. District shall calculate the amount of Fees owing, taking into account any Fee increases adopted by the District’s Board after Closing. District shall credit the Developer for Fees owing up to the Prepayment Amount. In the event that either the amount of square footage of the Project or the rate of the Fees increases prior to issuance of all building permits for the Project, then Developer shall be responsible to pay for any additional amounts owing above and beyond the Prepayment Amount. In the event that the rate of such Fees increases subsequent to Closing or the square footage of the Project increases, and the City issues any building permit(s) for the Project (or any portion thereof) prior to receipt of said certification from the District, then the City will be liable to the District for any incrementally increased amount of Fees or Fees associated with the added square footage. c. District Obligations.
371
{SR750989}
4 i. Consistent with the “Civic Center Act” and other applicable state law, District shall allow the American Canyon community to continue to use City Exchange Property, subject to adopted District policies/fee schedule.
ii. District has no obligation to maintain existing pedestrian access across ACMS Property.
iii. District has no obligation to maintain any trees, vegetation, or bank of the Rio Del Mar Creek that may be located on the ACMS Property. Notwithstanding the foregoing, any changes to the physical environment remain subject to local, state, and federal laws and regulations. Given that the pedestrian pathway bifurcates City Exchange Property, it is understood and acknowledged by the City that the community will likely not have access to the trees or vegetation through said Property after the exchange.

3. Consideration. In consideration of the property exchanges provided herein, the City shall convey the City Exchange Property via grant deed to the District, and the District shall convey the District Exchange Property via grant deed to the City.

In the event of any administrative, legal, or equitable action or other proceeding instituted by any person not a party to this Agreement challenging the validity of any provision of this Agreement or all actions, discretionary or ministerial, relating to the exchange of the Subject Properties, the Parties will agree to jointly defend the validity and implementation of the Agreement and to cooperate with one another to the extent practicable in defending against the claims so asserted, with each Party bearing its own attorneys’ fees and costs in connection with the defense of the Agreement. Participation in a joint defense as contemplated by this Agreement shall not constitute representation by counsel by one Party for another Party, nor shall such participation be grounds to disqualify counsel or experts from representing any Party. Further, each Party agrees to waive any conflict that may be created between Parties and/or their counsel and experts as a result of this Agreement. The Parties shall cooperate in defending such action or proceeding to settlement, stipulation, or final judgment including all appeals; provided, however, that nothing in this Section shall be construed as requiring either Party to defend a lawsuit or other administrative, legal, or equitable action or proceeding if such Party determines, in its sole and absolute discretion, that it would not be financially or otherwise prudent to do so.

10. Notices. Any notice, request, demand or other communication required or permitted to be given hereunder shall be in writing, may be personally served, telecopied, telexed or sent by an internationally recognized overnight delivery or courier service and shall be deemed to have been given when delivered in person or by courier or overnight service or upon receipt of a telecopy or telex, addressed to the recipients as follows:

CITY COUNCIL AGENDA
SEPTEMBER 6, 2022

STAFF REPORT

CONSENT
ITEM NUMBER: 10.

TITLE
2021 Annual Napa Airport Corporate Center Development Agreement Review

RECOMMENDATION
Adopt a Resolu)on finding that, during calendar year 2021, Napa Airport Corporate Center l, LLC (“Owner”) has provided “Good Faith Efforts” to comply with its obliga)ons in conjunc)on with the Napa Airport Corporate Center ("NACC") Development Agreement.

CONTACT
Brent Cooper, AICP, Community Development Director

BACKGROUND & ANALYSIS
On August 4, 2020, the Council approved the Napa Airport Corporate Center (Project) Development Agreement (DA) with, Napa Airport Corporate Center l, LLC (Ordinance No. 2020-03, Agreement 2020-08). The DA provides the owner with a 5-year vested right to develop the “Project Approvals” for the following entitlements that accommodate up to 193,741 square feet as follows:

1. A Tenta)ve Subdivision Map for subdivision of the Property into five lots, including public road rights-of-way;

2. Condi)onal Use Permits approving a Condi)onal Use Permit for Buildings A and B on Lots 1 and 2);

3. Conditional Use Permit and Design Permit for Building E on Lot 4;

4. Condi)onal Use Permit and Design Permit for Building G on Lot 5. These approvals allowed development of the Property with up to 261,541 square feet of industrial uses (warehouse, distribu)on, and/or E-commerce with accessory retail/office uses), and allowed the relaxa)on of certain lot size, front yard setbacks, and side yard landscaping requirements. The City condi)oned the approval of the Project on the Owner’s agreement to provide public infrastructure and other benefits to the City; and

5. On July 10, 2020, the Owner obtained approvals from the City for modifica)ons of the Condi)onal Use Permit/Design Permit for Building E on Lot 4 and Building G on Lot 5, which increased the area of preserved wetlands on Lot 4 and Lot 5, reduced the square footage and building site coverage of Building E and Building G, adjusted parking and loading consistent with the revised buildings and reduced overall development on the Property from approximately 261,541 square feet to approximately 193,741 square feet. 460
Furthermore, the Owner consented to the inclusion of the Property in the Green Island Road Community Facilities District.

Standards of Review
Annual review of Development Agreements is required by State law and Chapter 19.47 of the American Canyon Municipal Code. This annual report represents the 2021 Calendar Year monitoring report.

The burden of demonstra)ng good faith compliance is dependent on the Owner. On August 1, 2022, the Owner transmiIed a leIer to the City explaining the Project’s en)tlement status and progress made in substan)al compliance with the Development Agreement’s terms. A copy of this letter is included as Attachment 2 and is included in the Resolution as Exhibit A.

Development Agreement Public Benefits
Sec)on 3.3 of the Development Agreement describes substan)al public benefits the City will receive from the NACC Project. A table explaining each public benefit and its status is included as Attachment 3.

COUNCIL PRIORITY PROGRAMS AND PROJECTS
Economic Development and Vitality: "AIract and expand diverse business and employment opportunities."

FISCAL IMPACT
The fiscal impacts of the Projects were addressed as part of the Tenta)ve Parcel Map, Condi)onal Use Permits and Development Agreement.

ENVIRONMENTAL REVIEW
The annual Development Agreement monitoring report is categorically exempt from California Environmental Quality Act (CEQA) in accordance with Government Code 15321 – Enforcement Ac)ons by Regulatory Agencies (Class 21). Class 21 applies as an exemp)on because the annual Development Agreement monitoring report is intended to serve as a tool to enforce the Napa Logistics Park Phase 2 Development Agreement.

STAFF REPORT

CONSENT
ITEM NUMBER: 11.

TITLE
GHD Staff Augmentation - Encroachment

RECOMMENDATION
Adopt a Resolu+on authorizing the City Manager to execute Amendment #1 to Task Order #11 (2022-66) with GHD, Inc. for Encroachment Permit Processing and Construc+on Observa+on Services in an amount not to exceed $75,000.

CONTACT
Erica Ahmann Smithies, P.E., Public Works Director/City Engineer

BACKGROUND & ANALYSIS
Encroachment Permit services are required to maintain the integrity of City infrastructure. Public Works provides Encroachment Permit services to Developers, U+li+es and Residents. On June 21, 2022, City Council approved a new Engineering Technician posi+on in the City budget that will allow for Encroachment Permit services and inspec+ons to be handled internally. The City’s consultant for Encroachment Permit Services re+red on June 30, 2022 and in order to maintain the current level of service the City brought on GHD through the City's on-call contract agreement.

GHD’s contract has been necessary to bridge the gap between the recent re+rement and City recruitment process for a new Engineering Technician. Staff an+cipates the City posi+on will be filled within the next couple of months and the proposed amendment will provide for the addi+onal coverage.

The ini+al task order with GHD was for a not to exceed amount of $25,020 and the amendment will increase this to a total not to exceed amount of $75,000.

COUNCIL PRIORITY PROGRAMS AND PROJECTS
Organizational Effectiveness: "Deliver exemplary government services."

FISCAL IMPACT
The FY22/23 budget is sufficient for the recommended ac+on. Line item 100-50-515-42160 for nonreimbursable or flat rate encroachment permits and 105-60-660-42165, $15,020 will be offset by a 468
corresponding increase in revenue from major encroachment permits and developers who will reimburse the City for these costs.

ENVIRONMENTAL REVIEW
15378(b) - The ac+on is not a "Project" subject to the California Environmental Quality Act ("CEQA") because it does not qualify as a "Project" under Public Resources Code Sec+ons 21065 and 21080 and in Section 15378(b) of Title 14 of the California Code of Regulations.

PUBLIC HEARING
ITEM NUMBER: 12.

TITLE
Amendment of 2015 Urban Water Management Plan (UWMP) and Adop+on of 2020 Urban Water Management Plan (UWMP)

RECOMMENDATION
Conduct a Public Hearing and take the following actions:

1. Adopt a Resolu+on of the City Council of the City of American Canyon adop+ng the City's amendment to the 2015 Urban Water Management Plan - Appendix G Demonstra+on of Reduced Delta Reliance

2. Adopt a Resolu+on of the City Council of the City of American Canyon adop+ng the City's 2020 Urban Water Management Plan

CONTACT
Felix Hernandez, III, Maintenance and Utilities Director Dominic Patrick, Water Systems Manager

BACKGROUND & ANALYSIS
Background
In 1983, the State of California Legislature enacted the Urban Water Management Planning (UWMP) Act. The law required an urban water supplier, providing water for municipal purposes to more than 3,000 customers or serving more than 3,000 acre-feet annually, to adopt an Urban Water Management Plan every five years demonstra+ng water supply reliability in normal, single dry, and mul+ple dry water years. These plans support the suppliers’ long-term resource planning to ensure that adequate water supplies are available to meet exis+ng and future water needs. Within UWMPs, urban water suppliers must: assess the reliability of water sources over a 20-year planning +me frame, describe demand management measures and water shortage con+ngency plans, report progress mee+ng a targeted 20 percent reduc+on in per-capita urban water consump+on by the year 2020, and discuss the use and planned use of recycled water. The informa+on collected from the submitted UWMPs is useful for local, regional, and statewide water planning. (Attachment 4) Star+ng May 2016 Governor Brown’s execu+ve order B-37-16 directs an increased focus on improved water usage planning. In 2017, the California Department of Water Resources and several other agencies developed an implementa+on framework +tled "Making Conserva+on a California Way of Life" (Framework) Senate Bill 606 and Assembly Bill 1668 put forth requirements that were 486
adopted in the California Water Code to advance the goals of the order/framework including; use water more wisely, eliminate water waste, strengthen local drought resilience, improve agricultural water use efficiency and drought planning. (Attachment 5).

Analysis
New 2020 UWMP requirements are expected to cover a greater scope and increase the level of details as compared to the requirements for past rounds. Some of the biggest changes for municipal water purveyors include; more specific water conserva+on requirements aimed at mee+ng water use efficiency, standards for indoor residen+al use, outdoor residen+al use, commercial outdoor irriga+on and water loss. Enhanced requirements for evalua+ng water supply reliability including considera+on of climate change, impacts on supplies and demands, and developing a drought risk assessment to establish shortage condi+ons for a five-year drought. A Demonstra+on of Reduced Delta Reliance (AGachment 2) serves as a purpose to demonstrate compliance with the SacramentoSan Joaquin Delta Reform Act of 2009 and provide an analysis of the City's reduced reliance on the Delta and expected outcomes in accordance with State protocols.

COUNCIL PRIORITY PROGRAMS AND PROJECTS
Infrastructure: "Develop and maintain infrastructure resources to support sustainable growth."

FISCAL IMPACT
No fiscal impact.

ENVIRONMENTAL REVIEW
Providing the Water Conserva+on Plan ordinance is not a "project" under the California Environmental Quality Act ("CEQA"). Further, the item is categorically exempt from CEQA review as an ac+on by an agency for the protec+on of natural resources (pursuant to CEQA Guidelines sec+on 15307) and for the protection of the environment (pursuant to CEQA Guidelines section 15308).

Section 1

INTRODUCTION
The Sacramento-San Joaquin Delta Reform Act of 2009 requires State and local public agencies with a “covered action” to submit a written certification of consistency to the Delta Stewardship Council as to whether the covered action is consistent with applicable policies. The City of American Canyon (City) receives supply through the State Water Project (SWP) by contract with Napa County Flood Control and Water Conservation District (FCWCD) and through an agreement with Vallejo for Delta water. Both supplies impact the Sacramento-San Joaquin Delta (Delta). Covered actions can include a multi-year water transfer, conveyance facility, or new diversion that involves transferring water through, exporting water from, or using water in the Delta. Therefore, the City is required to demonstrate consistency with Delta Plan Policy WR P1 (Reduce Reliance on the Delta Through Improved Regional Water Self-Reliance). Delta Plan Policy WR P1 identifies Urban Water Management Plans (UWMP) as the tool to demonstrate consistency with State policy to reduce reliance on the Delta for a Supplier that carries out or takes part in a covered action.

The purpose of this document is to demonstrate compliance with the Sacramento-San Joaquin Delta Reform Act of 2009 and provide an analysis of the City’s reduced reliance on the Delta and expected outcomes in accordance with State protocols. The analysis provided herein includes the WR P1 requirements needed in a water supplier’s UWMP to support a certification of consistency for covered actions. The inclusion of this document as an appendix in the 2015 and 2020 UWMPs fulfills the requirements of WR P1. Future projects under evaluation will fulfill the requirements of WR P1.

Section 2
DELTA PLAN POLICY WR P1 REQUIREMENTS
WR P1 details the requirements for a covered action to demonstrate consistency with reduced reliance on the Delta and improved regional self-reliance. WR P1 subsection (a) states that:

Water shall not be exported from, transferred through, or used in the Delta if all of the following apply:
• One or more water suppliers that would receive water as a result of the export, transfer, or use have failed to adequately contribute to reduced reliance on the Delta and improved regional self-reliance consistent with all of the requirements listed in paragraph (1) of subsection (c).
• That failure has significantly caused the need for the export, transfer, or use. • The export, transfer, or use would have a significant adverse environmental impact in the Delta.
498
CITY OF AMERICAN CANYON | DEMONSTRATION OF REDUCED DELTA RELIANCE 2 | AUGUST 2022 | REVISED DRAFT
WR P1 subsection (c)(1) further defines what adequately contributing to reduced reliance on the Delta means in terms of (a) above. Water suppliers that have done all the following are contributing to reduced reliance on the Delta and improved regional self-reliance and are therefore consistent with this policy:
• Completed a current UWMP which has been reviewed by the California Department of Water Resources (DWR) for compliance with the applicable requirements of Water Code Division 6, Parts 2.55, 2.6, and 2.8;
• Identified, evaluated, and commenced implementation, consistent with the implementation schedule set forth in the Plan, of all programs and projects included in the Plan that are locally cost effective and technically feasible which reduce reliance on the Delta; and
• Included in the Plan, commencing in 2015, the expected outcome for measurable reduction in Delta reliance and improvement in regional self-reliance. The expected outcome for measurable reduction in Delta reliance and improvement in regional selfreliance shall be reported in the Plan as the reduction in the amount of water used, or in the percentage of water used, from the Delta watershed. For the purposes of reporting, water efficiency is considered a new source of water supply, consistent with Water Code section 1011(a).

California Code of Regulations (CCR), Title 23, § 5003(c) is followed by a description of programs and projects that reduce reliance on the Delta. Programs and projects that reduce reliance could include, but are not limited to, improvements in water use efficiency, water recycling, stormwater capture and use, advanced water technologies, conjunctive use projects, local and regional water supply and storage projects, and improved regional coordination of local and regional water supply efforts.

Section 3

DEMONSTRATION OF REDUCED DELTA

RELIANCE
The approach to determine the City’s reduced Delta reliance and improved regional self-reliance is consistent with the approach detailed by the California DWR in Appendix C of their “Urban Water Management Plan Guidebook 2020” (DWR Guidebook), issued in March 2021. The data used in the reduced reliance analysis for demands and supplies is detailed below. All data represent average or normal water year conditions and were obtained from the 2020 UWMP, previously adopted UWMPs, and City records.

The data inputs used in the reduced reliance analysis include:
• Water Years:
- Baseline (2010) – The analysis uses a normal water year representation of 2010 as the baseline, which is consistent with the approach described in the DWR 499
DEMONSTRATION OF REDUCED DELTA RELIANCE | CITY OF AMERICAN CANYON REVISED DRAFT | AUGUST 2022 | 3
Guidebook. Data for the City’s 2010 baseline are taken from City records and information presented in the City’s 2015 UWMP.
- 2015 and 2020 Conditions – The actual conditions for 2015 and 2020 are based on data reported in the City’s 2015 and 2020 UWMPs, respectively. - 2025-2045 Conditions – Normal year projections for 2025 through 2045 are taken from the City’s 2020 UWMP.
• Service Area Water Demands with Water Use Efficiency Accounted For – These values reflect the City’s actual and projected water use, including potable water demands, agricultural raw water, and losses.
• Non-Potable Water Demands – These values consist of agricultural raw water that is not treated.
• Population – Population data for 2010 and 2015 are taken from previous UWMPs. The population for 2020 and projected populations are taken from the 2020 UWMP. • Water Supplies Contributing to Regional Self-Reliance:
­ Water Use Efficiency – This amount is calculated by DWR’s spreadsheet tool based on the City’s baseline demand, actual demands, and projected demands. Calculated by multiplying the reduction in per capita water demand from the baseline (2010) for a year by the actual or projected population for the same year. For example, in 2025 there would be a gain of 481 acre-feet (AF) in supply from water use efficiency. ­ Water Recycling – Reflects the actual or projected recycled water delivered to customers within the City’s drinking water service area. Recycled water contributes to regional self-reliance by reducing the demand for potable water. Note that there was no recycled water delivered within the service area in 2010. For example, in 2025 there would be a gain of 625 AF in supply from water recycling. ­ Other Programs – Distribution loss reductions are anticipated due to City programs.

The 2020 UWMP assumed a water loss of 7.5 percent of potable demands. If this was reduced to 5.0 percent, it would contribute to reduced reliance. The difference between the losses estimated at 7.5 percent and 5.0 percent are included in the table for 2025-2045. For example, in 2025 the difference between 7.5 percent and

5.0 percent losses would be a gain of 63 AF in supply.
- Other categories in the table do not currently apply to the City’s supply portfolio.

Supply options the city is evaluating include surface water storage at Lake Curry, groundwater production wells outside of City limits, and potable reuse of recycled water.
• Water Supplies from the Delta Watershed:
- The City sub-contracts with the Napa County FCWCD for imported surface water from the SWP.
- The City has an agreement with Vallejo to purchase raw and treated water. Vallejo has an appropriative water right for Delta water from the State Water Resources Control Board (SWRCB) pre-dating the construction of the SWP.

Tables 1 and 2 contain demand calculations. Table 3 contains the regional self-reliance analysis and Table 4 contains the analysis of the City’s reduced Delta reliance. The tables were generated using DWR’s spreadsheet tool and fulfill the requirements of WR P1 subsection (c)(1) Paragraph C. 500

Section 4

EXPECTED OUTCOMES FOR REDUCED

RELIANCE ON THE DELTA
As stated in WR P1(c)(1)(C), commencing in 2015, UWMPs are required to include expected outcomes for measurable reduction in Delta reliance and improved regional self-reliance. WR P1 further states that those outcomes shall be reported in the UWMP as the reduction in the amount or percentage of water used from the Delta. The following provides a summary of the near-term (2025) and long-term (2045) expected outcomes for the City’s Delta reliance and regional self-reliance based on the assumptions described in the previous section and DWR’s analysis tool. The results show that the City is measurably reducing reliance on the Delta and improving regional self-reliance, based on the percentage of the City’s water supplies from the Delta watershed.

Expected Outcomes for Regional Self-Reliance (Table 3):
• Near-term (2025) – Normal water year regional self-reliance is expected to increase from 358 acre-feet per year (AFY) in 2015 to 1,169 AFY in 2025. This is achieved through water use efficiency, increased recycled water use, and distribution system loss reductions. • Long-term (2045) – Normal water year regional self-reliance is expected to increase from 1,169 AFY in 2025 to 2,149 AFY in 2045. This is achieved through water use efficiency, increased recycled water use, and distribution system loss reductions.

Expected Outcomes for Percent of Water Supplies from the Delta Watershed (Table 4):
• Near-term (2025) – Normal water year reliance on supplies from the Delta watershed is expected to decrease by approximately 45 percent relative to the 2010 baseline. • Long-term (2045) – Normal water year reliance on supplies from the Delta watershed is expected to decrease by approximately 6.6 percent relative to the 2010 baseline.

NEW APPENDIX TO 2015 UWMP
The information contained in this document is also included as a new Appendix G to the City’s 2015 UWMP, consistent with WR P1 subsection (c)(1)(C) (CCR, Title 23, Section 5003). As described in Chapter 10 of its 2020 UWMP, the City followed the required public notification, public review and hearing, and adoption processes required by the Urban Water Management Planning Act. Appendix G to the City’s 2015 UWMP, the 2020 UWMP (including this Appendix), and the City Municipal Code Water Conservation Plan Chapter 13.14 were adopted by the City Council on August 16, 2022 (see Appendix K of the 2020 UWMP). 501

Chapter 1

INTRODUCTION AND LAY DESCRIPTION

1.1 Lay Description
The City of American Canyon (City) is located at the southern end of Napa County, just north of Solano County and the City of Vallejo. The City is located approximately 45 miles west of Sacramento along Interstate I-80 and is approximately 5.5 square miles in size. American Canyon incorporated in 1992 from Napa County. Since its incorporation, the City has increased residential development and added a large amount of business and commercial expansion along the Highway 29 corridor.

The City’s potable water service area is approximately 30 square miles and encompasses the City limits and its sphere of influence and extends from the Napa River to the west to the Napa/Solano County line to the east and from the Napa/Solano County line to the south to Soscol Ridge north of the airport.

The City water supply is purchased or imported water sources, mainly State Water Project (SWP) water purchased from the Napa County Flood Control and Water Conservation District (FCWCD) and the City of Vallejo. The City owns, maintains, and operates the Water Treatment Plant (WTP) which has a maximum capacity of 5.5 million gallons per day (mgd) with an average daily demand of approximately 3 mgd. Treated water is delivered by gravity to the 2.5 million gallon (MG) water storage tank located at the WTP and flows from the tank to the distribution system.

The potable water distribution system consists of approximately 102 miles of water mains, 3 storage tanks, and 2 booster pump stations.

Water demands served by the City are primarily residential, including single-family residential (SFR) and multi-family residential (MFR), commercial, industrial, and institutional (CII), and landscape irrigation. All connections in the City are metered. The total demand (potable and non-potable) in 2020 was approximately 2,613 acre-feet (AF). Residential demands account for 1,454 AF (56 percent) of the total demand, while CII demands account for 763 AF (29 percent), and landscape irrigation demands account for 139 AF (5 percent). Raw water for agricultural irrigation was 63 AF (2 percent). The remaining balance is attributed to other uses (private fire protection services, temporary watering of construction sites) at 73 AF (3 percent) and water loss of 121 AF (5 percent). Based on the projected population growth rate, demands under normal conditions are anticipated to be 3,834 AF by the year 2045 with passive conservation. "Passive" savings are water savings from codes, standards, ordinances, or transportation and land use plans.

The per capita water demand was 116 gallons per capita per day (gpcd) in 2020. Although the City was able to meet the 2020 target of 162 gpcd, the year 2020 did not represent a typical year due to the impacts of the COVID-19 pandemic. Since the 2020 per capita demand of 116 gpcd was below the 2020 goal, adjustments for extraordinary events were not made. 522
CITY OF AMERICAN CANYON | 2020 URBAN WATER MANGEMENT PLAN 1-2 | AUGUST 2022 | REVISED DRAFT
Supply availability was reviewed under a single-dry year and a five-consecutive-year drought, in addition to a drought risk assessment (DRA) from 2021 through 2025. The City anticipates it can supply all its water demands by purchasing supplemental imported water through existing agreements through the planning horizon (2045) for all water year scenarios.

The City Water Conservation Plan Chapter 13.14 was also updated to address the latest requirements set forth by California Department of Water Resources (DWR) for drought planning, which now includes six supply shortage stages, response actions for demand reduction, supply augmentation, operational changes, and mandatory prohibitions to address shortage levels.

1.2 Background and Purpose
The California Water Code (CWC) requires urban water suppliers within the state to prepare and adopt an Urban Water Management Plan (UWMP) for submission to the DWR. The UWMP, which must be filed every five years, must satisfy the requirements of the Urban Water Management Planning Act (UWMPA) of 1983, including amendments that have been made to the Act. The UWMPA requires urban water suppliers servicing 3,000 or more connections, or supplying more than 3,000 AF of water annually, to prepare a UWMP.

The purpose of the UWMP is to maintain efficient use of urban water supplies, continue to promote conservation programs and policies, ensure that sufficient water supplies are available for future beneficial use, and provide a mechanism for response during water drought conditions. This document, which was prepared in compliance with the CWC, and as set forth in the 2020 Urban Water Management Plan Guidebook for Urban Water Suppliers (March 2021) established by the DWR, constitutes the City 2020 UWMP.

This 2020 UWMP was prepared in compliance with the UWMPA (CWC §10610 et seq.) and the Water Conservation Bill of 2009 (Senate Bill [SB] X7-7) by Carollo Engineers, Inc. (Carollo).

Contact information for the City and Carollo is included in the Contact Sheet provided at the beginning of this document.

The City recognizes the importance of maintaining a high-quality reliable water supply. Although water is a renewable resource, it is limited. A long-term reliable supply of water is essential to protect the local and state economy. The main focus for the City is to provide high quality water, maximize the efficient use of water, and promote conservation.

1.2.1 Previous Urban Water Management Plan
The City previously prepared an UWMP in 2015, which was approved and adopted on June 21, 2016. Following adoption, the 2015 UWMP was submitted to and formally approved by the DWR. The 2020 UWMP report serves as an update to the 2015 UWMP and pulls extensively from that report.

1.3 Urban Water Management Planning and the California Water Code The CWC sections applicable to UWMPs are summarized in the sections below.

1.3.1 Urban Water Management Planning Act
In 1983, State Assembly Bill (AB) 797 modified the CWC Division 6 by creating the UWMPA.

Several amendments to the original UWMPA, which were introduced since 1983, have increased the data requirements and planning elements to be included in the UWMPs. 523
2020 URBAN WATER MANGEMENT PLAN | CITY OF AMERICAN CANYON REVISED DRAFT | AUGUST 2022 | 1-3
Initial amendments to the UWMPA required that total projected water use be compared to water supply sources over the next 20 years, in 5-year increments. DWR guidelines also suggest projecting through a 25-year planning horizon to maintain a 20-year timeframe until the next UWMP update has been completed.

Other amendments require that UWMPs include provisions for recycled water use, demand management measures (DMMs), and a Water Shortage Contingency Plan (WSCP). The UWMPA requires a WSCP which meets the specifications set forth therein. Recycled water was added in the reporting requirements for water usage and figures prominently in the requirements for evaluation of alternative water supplies, when future projections predict the need for additional water supplies. Each urban water purveyor must coordinate the preparation of the WSCP with other urban water purveyors in the area, to the extent practicable. Water suppliers must also describe their water DMMs that are being implemented or are scheduled for implementation.

In addition to the UWMPA and its amendments, there are several other regulations that are related to the content of the UWMP. In summary, the key relevant regulations are:
• AB 1420: Requires implementation of DMMs/best management practices (BMPs) and meeting the 20-by-2020 targets to qualify for water management grants or loans. • AB 1420: Requires a plan to quantify and report on distribution system water loss. • AB 1420: Provides for water use projections to display and account for the water savings estimated to result from adopted codes, standards, ordinances, or transportation and land use plans, when that information is available and applicable to an urban water supplier.
• AB 1465: Requires water suppliers to describe opportunities related to recycled water use and stormwater recapture to offset potable water use. • Amendments SB 610 (Costa, 2001) and AB 901 (Daucher, 2001): Require counties and cities to consider information relating to the availability of water to supply new large developments by mandating the preparation of further water supply planning (Daucher) and Water Supply Assessments (Costa).
• SB 1087: Requires water suppliers to report SFR and MFR projected water use for lower income areas separately.
• Amendment SB 318 (Alpert, 2004): Requires the UWMP to describe the opportunities for development of desalinated water, including but not limited to, ocean water, brackish water, and groundwater, as long-term supply.
• AB 105 (Wiggins, 2004): Requires urban water suppliers to submit their UWMPs to the California State Library.
• SB X7-7: Requires development and use of new methodologies for reporting population growth estimates, base per capita use, and water conservation. An agency can choose from four methods to establish their interim (2015) and year 2020 water conservation targets.
• AB 2067: Requires water suppliers to provide narratives of water DMMs. • SB 1036: Provides for an urban water supplier to include certain energy-related information, including, but not limited to, and estimate of the amount of energy used to extract or divert water supplies.
• AB 2409: Requires urban water suppliers to analyze and define water features that are artificially supplied with water, including ponds, lakes, waterfalls, and fountains separately from swimming pools and spas.

1.3.2 New Requirements to the Water Code since the 2015 UWMPs The major new requirements to the CWC since 2015 UWMPs are summarized in Table 1-1.

Table 1-1: Applicable Changes to the Water Codes since 2015 UWMPs Topic Summary
Five Consecutive
Dry-Year Water
Reliability
Assessment
The Legislature modified the dry-year water reliability planning from a “multiyear” time period to a “drought lasting five consecutive water years” designation.

Drought Risk
Assessment
(DRA)
The DRA requires a Supplier to assess water supply reliability over a five-year period from 2021 to 2025 that examines water supplies, water uses, and the resulting water supply reliability under a reasonable prediction for five consecutive dry years.

Seismic Risk Requires Suppliers to specifically address seismic risk to various water system facilities and to have a mitigation plan.

Energy Use
Requires Suppliers to include readily obtainable information on estimated amounts of energy for their water supply extraction, treatment, distribution, storage, conveyance, and other water uses.

Water Loss
Reporting for
Five Years
The Water Code added the requirement to include the past five years of water loss audit reports as part of this UWMP.

WSCP New requirements are more prescriptive than previous versions.

Groundwater
Supplies
Coordination
Water Code now requires Suppliers’ 2020 UWMPs to be consistent with Groundwater Sustainability Plans, in areas where those plans have been completed by Groundwater Sustainability Agencies.

Lay Description
Suppliers to include a lay description of the fundamental determinations of the UWMP, especially regarding water service reliability, challenges ahead, and strategies for managing reliability risks. This section of the UWMP could be viewed as a go-to synopsis for new staff, new governing members, customers, and the media, and it can ensure a consistent representation of the Supplier’s detailed analysis.

1.3.3 Water Conservation Act of 2009 (SB X7-7)
Beginning in 2016, retail water suppliers are required to comply with the water conservation requirements in SB X7-7 in order to be eligible for State water grants or loans. Refer to Chapter 5 for detailed information on SB X7-7.

PLAN PREPARATION
This section includes specific information on how the UWMP was developed, including efforts in coordination and outreach.

2.1 Basis for Plan Preparation
CWC 10617 requires that urban water suppliers with 3,000 or more service connections or supplying 3,000 or more AF of water per year prepare an UWMP every five years. 10617 “Urban water supplier” means a supplier, either publicly, or privately owned, providing water for municipal purposes either directly or indirectly to more than 3,000 customers or supplying more than 3,000 acre-feet of water annually. An urban water supplier includes a supplier or contractor for water, regardless of the basis of right, which distributes or sells for ultimate resale to customers. This part applies only to water supplied from public water systems…

2.1.1 Public Water Systems
California Health and Safety Code 116275 (h) “Public Water System” means a system for the provision of water for human consumption through pipes or other constructed conveyances that has 15 or more service connections or regularly serves at least 25 individuals daily at least 60 days out of the year.

To demonstrate the basis of reporting, the Public Water Systems services by the City are listed in Table 2-1. As listed in Table 2-1, the City served 1 public water system with a total of 5,341 connections and a total of 2,613 acre-feet per year (AFY) in year 2020.

3.3 Service Area Population and Demographics
10631(a). Describe the service area of the supplier, including current and projected population… The projected population estimates shall be based upon data from the state, regional, or local service agency population projections within the service area of the urban water supplier and shall be in five-year increments to 20 years or as far as data is available.

This section summarizes historical, current, and projected population trends in the City.

Population projections are essential to the planning process and form the basis for most planning decisions, yet projecting future growth is far from an exact science given the complex set of variables that can affect the rate of growth. Typically, projections are developed by taking past patterns and combining them with assumptions regarding the future to obtain an estimate of future growth rates. These projections serve to provide the City insight on the type and 534
CITY OF AMERICAN CANYON | 2020 URBAN WATER MANGEMENT PLAN 3-4 | AUGUST 2022 | REVISED DRAFT
quantity of future growth as well as guidance regarding future planning activities; therefore, such planning activities can only be as effective as the ability to anticipate population growth.

3.3.1 Service Area Population
The current and projected population within the City’s water service area is summarized in Table 3-1 and includes the total populations within the City limits and outside of the City limits as described in the following sections.

Table 3-1: Population - Current and Projected

3.3.1.1 Population within City Limits
The City experienced rapid growth between 2000 and 2008 with an average annual growth rate of over 8 percent. Population growth has slowed in recent years, and the annual growth rate since 2010 has been around 1 percent (2015-2023 Housing Element).

The California Department of Finance (DOF) estimates population each year based on the number of building permits issued, residential units destroyed, requests for new electrical connections, etc. The City had a population of 19,454 in 2020 according to the most recent DOF estimates.

The projected population within the City limits was estimated based on the following specific plans for new developments which are expected to contribute to housing growth in the City:
• Watson Ranch Project: Approximately 1,253 housing units are expected to be added in the northeastern portion of the City.
• Broadway District Priority Development Area (PDA): Approximately 1,200 housing units are expected to be added along the Highway 29 corridor.

Other proposed development projects in planning and approval phases were not incorporated in the population projections.

To estimate the new population within the City limits, the total number of new housing units (2,453) was multiplied by the number of persons per household for the City for 2020, which was

3.43 according to the most recent DOF estimates. Based on this calculation, the new population within the City limits is estimated to be 8,414. Assuming that this population growth is distributed between 2020 and 2040, this results in a population increase of 2,104 every 5 years.

For 2040 to 2045, it was assumed that the population growth rate would remain at 8 percent every 5 years (same rate as 2035 to 2040).

3.3.1.2 Population Outside of City Limits
Less than 1 percent of the City’s single-family residential customers are located outside of the City limits in unincorporated Napa County in areas that have not experienced any housing development. These “legacy” accounts were originally connected and served by the American Canyon County Water District, a predecessor to the City.

To estimate the population outside of the City limits, the number of residential accounts in 2020 (28) was multiplied by the number of persons per household for unincorporated Napa County for 2020, which was 2.48 according to the most recent DOF estimates. Based on this calculation, the population outside of the City limits is estimated to be 70. For 2025 to 2045, it was assumed that there would be no change to the population outside of the City limits.

3.3.2 Other Social, Economic and Demographic Factors
10631. Describe the service area of the supplier, including… other social, economic and demographic factors affecting the supplier’s water management planning.

Analyzing demographic data can yield important information about possible shifts in demand for City water service.

According to the 2015-2023 Housing Element, the largest employment sectors are educational services (28.1 percent), Manufacturing (12.1 percent), and art, entertainment, and recreational services (10.1 percent).

The 2015-2023 Housing Element indicates that the majority of housing units are single-family detached homes (81.8 percent) and the number of housing units was 6,071 in 2014.

74.3 percent of the population is over 18 years of age and the population is split 49.8 to

50.2 percent male to female, respectively (United States Census Bureau QuickFacts).

Table 4-C.4 of the SB X7-7 Compliance Form (Appendix C) shows that the California Median Household Income in 2020 was $75,235. The median household income for the City from 2015-2019 in 2019 dollars was $101,792 (United States Census Bureau QuickFacts).

The California Employment Development Department (EDD) reported a 5.5 percent unemployment rate for 2015 and a 10.0 percent unemployment rate for 2020.

3.4 Land Uses within Service Area
10631(a). The description shall include the current and projected land uses within the existing or anticipated service area affecting the supplier’s water management planning. Urban water suppliers shall coordinate with local or regional land use authorities to determine the most appropriate land use information, including, where appropriate, land use information obtained from local or regional land use authorities…
The City’s existing General Plan was adopted in 1992. The City is in the process of completing a comprehensive General Plan update. The Land Use Element in the General Plan sets forth the City’s policies for guiding local development. The existing land uses within the City Limits are summarized in Table 3-2.

3.5 Climate Change
Climate change mitigation and adaptation efforts are being implemented as part of the 2020 UWMP Guidebook update. Projected climate change trends for California include increasing temperature and increasing precipitation as rainfall rather than snow. Water suppliers are now having to assess local climate challenges and plan for vulnerabilities within their systems. As these risks are identified, methods of adaption and mitigation can be employed to increase sustainability of water resources.

In the past decade, there has been a significant increase in tools and models to help identify potential impacts of climate change. The various resources differ in the information available in each service area, scenario assumptions, and parameters potentially impacted by climate change. The following tools were evaluated for this UWMP and are described in further detail in the sections below:
• Climate Resilience Evaluation and Awareness Tool (CREAT). • Cal-Adapt Extended Drought Scenarios Tool.
• Cal-Adapt Wildfire Tool.

3.5.1 EPA Climate Resilience Evaluation and Awareness Tool The United States Environmental Protection Agency (EPA) created an online resource called CREAT to assist water agencies in preparing for potential future impacts on their systems caused by climate change. This tool utilizes model simulation to estimate changes in temperature, precipitation, storms, extreme heat, and sea level rise. For the purposes of this UWMP, the Cal-Adapt tool was used, which is consistent with the tool presented by DWR.

3.5.2 Cal-Adapt Extended Drought Scenarios Tools
Cal-Adapt is an online resource created by the State of California’s scientific and research community to provide visualization tools and high-quality data regarding climate change at a local level. This resource allows the user to explore charts, maps, data, and projected climate variables for the State of California, and is a key recommendation of the 2009 California Climate Adaptation Strategy and the DWR. All projections generated include two possible climate outcomes; one scenario where greenhouse gas (GHG) emissions peak near year 2040 and decline 537
2020 URBAN WATER MANGEMENT PLAN | CITY OF AMERICAN CANYON REVISED DRAFT | AUGUST 2022 | 3-7
beyond 2040 (medium, Representative Concentration Pathway [RCP] 4.5), and another in which GHG emissions continue to rise throughout the 21st century (high, RCP 8.5). The tool allows the user to search by watershed, grid, counties, census tracts, and incorporated and census designated places. Thus, this tool was used to evaluate the impacts of climate change within the City’s service area using the medium, RCP 4.5, and high, RCP 8.5, GHG emission scenarios.

The Extended Drought tool was used to evaluate early- and late-century variable climate impacts for the City watershed over a 20-year drought including 5 years prior and 4 years following. This two-decade extended drought period is often referred to as a “mega-drought.” The results, which include minimum and maximum temperature, precipitation, ETo, and runoff, are summarized in Table 3-3.

The projected increase in maximum temperature from historical years to late-century is 6.6°F (9.3 percent), whereas the projected increase in minimum temperature is 5.7°F (12.5 percent).

Precipitation is projected to decrease by 3.4 inches by late-century (15.0 percent), ETo by

0.9 inches (5.9 percent), and runoff by 0.4 inches (14.8 percent).

3.5.3 Cal-Adapt Wildfire
The Cal-Adapt Wildfire tool utilizes four models identified by the California Climate Action Team as priority models contributing to the 2018 California Fourth Climate Change Assessment. The models listed below describe the scenarios used in area burned wildfire projections. • Warm/dry scenario (HadGEM2-ES).
• Cooler/wetter scenario (CNRM-CM5).
• Average scenario (CanESM2).
• A scenario that is unlike the first three models, the “complement” scenario (MIROC5).

The model projections generated include the same two possible climate outcomes: RCP 4.5 and RCP 8.5. Time periods for the wildfire analysis include historical (1961-1990), mid-century (2035-2064), and end of the century (2051-2070). The population growth scenario for the City service area was identified as central, or median. Summary statistics of all four priority models under medium and high RCP conditions are below in Table 3-4. 538

WATER USE CHARACTERIZATION
The UWMPA requires that the UWMP identify the quantity of water supplied to the agency’s customers including a breakdown by user classification. This section describes the water system demands and water demand projections.

4.1 Non-Potable Versus Potable Water Use
This chapter covers potable and raw water demand. Recycled water is addressed comprehensively in Chapter 6.

4.2 Past, Current, and Projected Water Use by Sector
10631(d). (1) For an urban retail water supplier, quantify, to the extent records are available, past and current water use, over the same five-year increments described in subdivision (a), and projected water use, based upon information developed pursuant to subdivision (a), identifying the uses among water use sectors, including, but not necessarily limited to, all of the following… (2). The water use projections shall be in the same five-year increments described in subdivision (a).
(4)(A) Water use projections, where available, shall display and account for the water savings estimated to result from adopted codes, standards, ordinances, or transportation and land use plans identified by the urban water supplier, as applicable to the service area. (B) To the extent that an urban water supplier reports the information described in subparagraph (A), an urban water supplier shall do both of the following: (i) Provide citations of the various codes, standards, ordinances, or transportation and land use plans utilized in making the projections. (ii) Indicate the extent that the water use projections consider savings from codes, standards, ordinances, or transportation and land use plans. Water use projections that do not account for these water savings shall be noted of that fact.

The following water use sectors and associated metered deliveries, as shown in Table 4-0, were reported in the 2015 UWMP.

• Commercial and Industrial: Assumed net 50 percent increase from 2020 demand (685 AFY) by 2045 (build-out). Application materials have been received by the City for a proposed South Napa Industrial Project. The project’s annual potable water demand is estimated to be a maximum of 109 AFY. The commercial and industrial potable water demand projection assumption will be revisited during preparation of the 2025 UWMP when more information about this project, such as planned implementation year, is available.
• Institutional: Assumed to remain at the 2020 water use through 2045 (78 AFY). • Landscape: Assumed to remain at the 2020 water use through 2045. Potable water demand for landscape irrigation is expected to decrease as conversion to recycled water occurs (see Table 6-6). The Water Waste Prohibitions Ordinance (City Municipal Code Section 13.14.060) and City Municipal Code Chapters 16.14 and 19.22 may also contribute to “passive” water savings (see Section 9.1). • Agricultural Irrigation: Assumed to remain at the 2020 water use through 2030 and be 0 AF by 2035 as conversion to recycled water occurs (see Table 6-6 Project RW13). • Other Potable (private fire protection services, temporary watering of construction sites): Assumed to remain at the 2020 water use through 2045. • Losses: Assumed to be 7.5 percent of the total projected potable water use.

10631.1(a). The water use projections required by Section 10631 shall include projected water use for single-family and multifamily residential housing needed for lower income households, as defined in Section 50079.5 of the Health and Safety Code, as identified in the housing element of any city, county, or city and county in the service area of the supplier.

As shown in Table 4-5, lower income household demand projections are included in the total water use projections (Table 4-2 and Table 4-3).

The Regional Housing Needs Assessment (RHNA) is mandated by State Housing Law as part of the periodic process of updating local housing elements of the General Plan. The RHNA for the City for the 2014 to 2022 projection period is 392 new housing units, including 116 very low-income units, 54 low-income units, 58 moderate-income units, and 164 above moderate-income units (2015-2023 Housing Element). It should also be noted, State legislation in 2017 made Accessory Dwelling Units (ADU) legal in all California cities. Homeowners can decide to build either a detached ADU in their backyard, an attached ADU that is part of a home addition, or an ADU conversion. Although the State has determined ADU’s contribute no additional stress on utilities, the addition of another dwelling unit, another family occupant, on a single-family property does impact water usage.

4.6 Climate Change Considerations
As temperature rises, water demands from various types of users will likely increase. Daily heat patterns, such as the duration of daytime heat prior to nighttime cooling, will change the diurnal demand patterns and peaking factors for activities, such as landscaping and other outdoor water use features (e.g., pools, fountains, open water bodies), due to increased ET values. The altered climate patterns in California creating hotter days and longer heat waves will increase customer water use and evaporative water losses. Extended drought periods are expected to become both more frequent, and more severe, which could lead to reduced rainfall and snowpack.

The combination of a long-term reduction in water supply availability with a long-term increase in water demand and higher summer demand peaks will increase pressure on the City to meet demands. Technology and devices to increase monitoring through the distribution system will help the City prepare for, and respond to, changes in supply and demand due to climate change.

Creating redundancy through backup systems, the addition of pipes to connect dead ends or areas only served by one main line or water source, will help the City achieve efficiencies required in the face of climate change considerations. Getting localized, region specific data on climate change forecasts and impacts would also help the City for planning purposes.

The City’s service area is predicted to have declining precipitation and increasing temperatures.

The increasing temperatures may change demand levels and patterns. Continued reduction in per capita demand with water conservation will become more challenging as BMP saturation levels climb. It can be concluded that climate change will likely put more strain on the City’s ability to meet demands long-term. If per capita water demand were to increase with temperature, or the population were to increase at a higher rate, or purchased or imported water supplies were to decrease due to extended droughts, or water availability were to be impacted due to wildfires, the effects could have serious and devastating consequences. 545

The UWMPA requires that the UWMP identify the baseline water demand, urban water use target, and interim urban water use target for the City. In the 2015 UWMP, water use targets were determined per the DWR Methodologies. The daily per capita water use, expressed in gpcd, is the total water use within the service area divided by the population. These targets are necessary to judge compliance with the 2020 use reductions set forth in the Water Conservation Bill of 2009 (SB X7-7).

The purpose of this section in the 2020 UWMP is to determine whether the City has met the 20 percent conservation mandate. All SB X7-7 forms are included in Appendix C.

5.1 2015 UWMP Baseline and Targets
A supplier may update the baseline and target water use if there were changes to their distribution area. The City’s distribution area has not changed since 2015. Therefore, the baseline and target gpcd values from the 2015 UWMP are utilized in this UWMP to determine compliance with the 2020 target.

In the 2015 UWMP, a 10-year baseline and a 5-year baseline were calculated to establish the minimum criteria for the City water use reduction targets. A summary of the 2008 total and recycled water deliveries, 10-year baseline range (1999 to 2008), and 5-year baseline range (2003 to 2007) is included in Table 1 of the SB X7-7 Verification Forms (Appendix C).

5.2 Service Area Population
10608.20. (e) An urban retail water supplier shall include in its urban water management plan due in 2010… the baseline per capita water use… along with the bases for determining those estimates, including references to supporting data.
(f) When calculating per capita values for the purposes of this chapter, an urban retail water supplier shall determine population using federal, state, and local population reports and projections.
10644. (a)(2) The plan… shall include any standardized forms, tables or displays specified by the department.

As shown in Table 2 of the SB X7-7 Verification and Compliance Forms (Appendix C), the 2020 population is per SB X7-7 Method for Population Finances 1 (DOF Table E-5) and per SB X7-7 Method for Population Finances 2 (Persons-per-Connection Method). Refer to Section 3.3.1 for additional details.
546
CITY OF AMERICAN CANYON | 2020 URBAN WATER MANGEMENT PLAN 5-2 | AUGUST 2022 | REVISED DRAFT
Service area population is reported for each year in the baseline periods as well as 2015 in Table 3 of the SB X7-7 Verification Form (Appendix C). Service area population is reported for 2020, the compliance year, in Table 3 of the SB X7-7 Compliance Form (Appendix C).

5.3 Gross Water Use
10608.12 (g) "Gross Water Use" means the total volume of water, whether treated or untreated, entering the distribution system of an urban retail water supplier, excluding all of the following:
(1) Recycled water that is delivered within the service area of an urban retail water supplier or its urban wholesale water supplier
(2) The net volume of water that 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.
“Gross Water Use” is the total volume of water, whether treated or untreated, entering the distribution system of an urban retail water supplier with certain acceptable exclusions. Gross water use is reported for each year in the baseline periods as well as 2015 and 2020, the compliance year, in Table 4 of the SB X7-7 Verification and Compliance Forms (Appendix C).

5.4 Baseline Daily Per Capita Water Use
The baseline daily per capita water use in each of the baseline years is calculated in Table 5 of the SB X7-7 Verification Form (Appendix C) by dividing annual gross water use by annual service area population. The average baseline daily per capita water use is summarized in Table 6 of the SB X7-7 Verification Form (Appendix C) for the 10-year baseline, 5-year baseline, and 2015. The average baseline daily per capita water use is summarized in Table 5 of the SB X7-7 Compliance Form (Appendix C) for the 2020 compliance year.

5.5 Baselines and Targets Summary
As mentioned above, a supplier may update the baseline and target water use if there were changes to their distribution area. The City’s distribution area has not changed since 2015.

Therefore, the baseline and target gpcd values from the 2015 UWMP are utilized in this UWMP to determine compliance with the 2020 target.

Based on the water use targets calculated in 2015, the City water use target for 2020 is 162 gpcd.

Based on the 10-year baseline of 203 gpcd, the 2015 interim water use target was 183 gpcd. The 2020 target was determined using Method 1. In order to meet the confirmation criteria, the 2020 target must fall below 95 percent of the 5-year baseline, which for the City is 204 gpcd.

According to the DWR guidelines, the 2020 target is valid since it is less than the target confirmation criteria of 194 gpcd.

A summary of the various baselines and the confirmed 2020 target are summarized in Table 5-1.

Refer to Table 7 and Table 8 of the SB X7-7 Verification Form (Appendix C) for more information on the calculation method and a summary of the targets. 547

Chapter 6

WATER SUPPLY CHARACTERIZATION
The UWMPA requires that the UWMP include a description of the agency’s existing and future water supply sources for the next 20 years. The description of water supplies must include detailed information on surface water, groundwater, the groundwater basin, potential opportunities for desalination of groundwater and seawater, and detailed information on the agency’s imported water.

6.1 Purchased or Imported Water
The City’s water supply is imported water from the SWP in addition to other supplemental imported water sources as described in the following subsections. The City also purchases water from the City of Vallejo

6.1.1 State Water Project
The main source for the City’s water supply is from the SWP, which is operated by DWR. SWP water used by the City is diverted from the Sacramento-San Joaquin Delta (Delta) and conveyed approximately 27 miles through the North Bay Aqueduct (NBA) system to the City’s WTP.

6.1.1.1 “Table A” Allotment
In 1967, the City (operating then as the American Canyon County Water District) entered into an agreement with the Napa County FCWCD for annual allotments of SWP water (i.e., “Table A” allotments). The City’s contract with Napa County FCWCD is through 2035 and includes provisions for extensions. It is anticipated that the contract will be extended through 2085.

The City’s current “Table A” allotment is 5,200 AFY. The actual amount of SWP water available to the City varies from year-to-year due to hydrologic conditions, water demands of other SWP contractors, SWP facility capacity, and environmental/regulatory requirements.

6.1.1.2 Article 21 Water
In certain years, the City may also receive additional SWP water known as Article 21 water, which is identified in Article 21 of SWP long-term water supply contracts between DWR and each SWP water contractor. The year-to-year availability of the Article 21 water supply varies and Article 21 water becomes available only when the following conditions are met:
• Such deliveries do not interfere with SWP “Table A” allocations and SWP operations. • Excess water is available in the Delta.
• Capacity is not being used for SWP purposes or scheduled SWP deliveries. • Contractors can use the SWP Article 21 water directly or can store it in their own system (i.e., the water cannot be stored in the SWP system).
550
CITY OF AMERICAN CANYON | 2020 URBAN WATER MANGEMENT PLAN

6.1.2 City of Vallejo
As described in the following subsections, the City has an agreement with the City of Vallejo to purchase the following water types:
• Vallejo Permit Water (raw water).
• Vallejo Treated Water (potable water).
• Vallejo Emergency Water (raw water).

6.1.2.1 Vallejo Permit Water
Vallejo has an appropriative water right for Delta water from the State Water Resources Control Board (SWRCB) referred to as Vallejo Permit Water. The City purchased 500 AFY of this water supply from the City of Vallejo in 1996, which is delivered through the SWP’s NBA system. Since the City began receiving Vallejo Permit Water in 1999, the City has received 100 percent of the full contracted volume every year.

6.1.2.2 Vallejo Treated Water
The City also purchases up to 628.6 AFY of Vallejo Treated Water (potable water). Vallejo Treated Water is delivered via three (3) connection points to Vallejo's potable water water distribution system located within the City.

6.1.2.3 Vallejo Emergency Water
The City purchases up to 500 AFY of Vallejo Emergency Water (raw water) only in years when the City’s “Table A” allotment is curtailed.

6.1.3 Other Imported Water Sources
In addition to the primary supply sources described previously, in some years, the City also uses other supplemental imported water sources as described in the following subsections. The availability of these water supplies vary from year-to-year.

6.1.3.1 Other State Water Project Sources
Dry Year Water Purchase Program
DWR’s Dry Year Water Purchase Program (or Dry Year Water Bank) allows interested SWP contractors in dry years the option to purchase emergency water supplies from Sacramento Valley rice farmers, if supply is made available.

Article 56 Carryover Water
DWR’s Article 56 Carryover Program allows water that is allocated to an SWP contractor but not used by the end of the year to be used in the next year. This water is exported from the Delta by the Banks Pumping Plant and stored in the San Luis Reservoir. “Table A” Exchange Return Water
DWR’s “Table A” Exchange Return Water Program allows interested SWP contractors to receive a portion of another SWP contractors approved “Table A” allotment in exchange for return of future approved SWP “Table A” water at an established exchange ratio. 6-2 | AUGUST 2022 | REVISED DRAFT
551
2020 URBAN WATER MANGEMENT PLAN | CITY OF AMERICAN CANYON REVISED DRAFT | AUGUST 2022 | 6-3
Turn-Back Water Pool Program
DWR’s Turn-Back Water Pool Program allows interested SWP contractors the option to buy and sell unused “Table A” water. The City has not purchased water through this program since 2016.

Dry-Year Transfer Program
DWR’s Dry Year Transfer Program allows for transfers in dry years through a combination of crop idling, groundwater substitution, and changes in reservoir operation. The City has not purchased water through this program since 2015.

Yuba Accord Dry-Year Water
The Lower Yuba River Accord is an agreement to settle issues related to in-stream flows in the Yuba River and fisheries habitat. The Yuba Accord Dry-Year Water Purchase Agreement allows interested SWP contractors the option to purchase water in dry years. The City has not purchased water through this program since 2015.

6.1.3.2 City of Napa
The agreement with Napa allows the City to purchase treated (potable) water under emergency conditions or when the NBA system or City WTP is offline for maintenance or other reasons. This water source would be deducted from the City’s SWP “Table A” allotment. The City has not purchased water through this program since 2014.

6.2 Groundwater
The City is located over the Napa-Sonoma Valley Lowlands Subbasin (identified as Groundwater Basin Number 2-002.03 by DWR). Previous studies of groundwater productivity in and near the City have indicated that usable groundwater resources in the City may be limited. As shown in Table 6-1, the City does not operate groundwater wells within the City limits for water supply.

6.4 Stormwater
The City has not identified any opportunities related to stormwater recapture to offset potable water use.

6.5 Wastewater and Recycled Water
The UWMPA requires that the UWMP address the opportunities for development of recycled water, including the description of existing recycled water applications, quantities of wastewater currently being treated to recycled water standards, limitations on the use of available recycled water, an estimate of projected recycled water use, the feasibility of said projected uses, and practices to encourage the use of recycled water.

6.5.1 Recycled Water Coordination
10633. The plan shall provide, to the extent available, information on recycled water and its potential for use as a water source in the service area of the urban water supplier. The preparation of the plan shall be coordinated with local water, wastewater, groundwater, and planning agencies that operate within the supplier's service area.

The City and NSD provide municipal wastewater and recycled water services within the City’s water service area.

The City provides wastewater collection, treatment and disposal services as well as recycled water services within the City limits as well as the Extra Territorial Sewer Service Area (ETSSA) located north of the City. Note that the ETSSA excludes the Chardonnay Golf Course and the Napa County Airport.

NSD provides wastewater collection, treatment and disposal as well as recycled water services for the City of Napa and portions of unincorporated Napa County, including northern portions of the City’s water service area.

The City’s and relevant portions of the NSD’s sewer/recycled water service area is shown in Figure 3-1.

6.5.2 Wastewater Collection, Treatment Systems, and Disposal 10633. (a) (Describe) the wastewater collection and treatment systems in the supplier's service area, including a quantification of the amount of wastewater collected and treated and the methods of wastewater disposal.

The City’s wastewater collection system consists of gravity pipelines, two force mains (the Main and Industrial Basins from the southern and northern ends of the City, respectively), and a series of pump stations. The wastewater is conveyed to the City’s Water Reclamation Facility (WRF) located near the City’s northwest limits (see Figure 3-1) for treatment.

NSD collects wastewater from the residents and businesses in the City of Napa, Silverado Country Club, the Napa County Airport and several adjacent unincorporated areas, including northeastern portions of the City’s water service area. The wastewater is conveyed to NSD’s Soscol Water Recycling Facility (WRF), located outside the City’s water service area northwestern border (see Figure 3-1) for treatment.
553
2020 URBAN WATER MANGEMENT PLAN | CITY OF AMERICAN CANYON REVISED DRAFT | AUGUST 2022 | 6-5
The 2020 wastewater flows from the City's service area is summarized in Table 6-2. As shown in Table 6-2, the City contributed 1,952 AFY of wastewater flow into the City’s WRF and 139 AFY of wastewater flow into the NSD’s Soscol WRF in 2020.

Table 6-2: Wastewater Collected Within Service Area in 2020

6.5.3 Wastewater Treatment and Discharge within Service Area The City owns, maintains, and operates the WRF. The WRF has a total wastewater treatment capacity of 2.5 mgd at average dry weather flow conditions and 5.0 mgd at peak wet weather flow conditions.

The WRF facilities consists of an emergency overflow basin, headworks, micro-screening, grit removal, four parallel biological treatment basins that use membrane bioreactor (MBR) technology, and disinfection. The four treatment trains can be used to segregate domestic wastewater (Main Aeration Basin) from industrial wastewater (North Aeration Basin). The WRF has separate disinfection systems for treated wastewater discharges and recycled water.

Treated wastewater discharges are disinfected by ultraviolet light (UV). Recycled water is disinfected using chlorine. Biosolids generated during the treatment process are stored in two sludge storage basins, until dewatered with a screw press and hauled to a landfill for disposal.

Treated wastewater discharges are regulated under National Pollutant Discharge Elimination System (NPDES) Waste Discharge Requirements (WDR) Order No. R2-2017-0008. Discharge is allowed to the North Slough on the Napa River (Discharge Point No. 001) and to two constructed freshwater wetlands that are tributary to the North Slough (Discharge Point No. 003). Treated wastewater is discharged from Discharge Point No. 001 during the wet season (November 1 Name of

21 City-owned facilities for landscape irrigation, and temporary users for dust control at construction projects.

The current and projected recycled water uses are summarized in Table 6-4. An analysis conducted for the City’s Recycled Water Master Plan (May 2016) estimated that the 2016 demand for recycled water was approximately 68 AFY for agricultural (vineyard) irrigation and 180 AFY for landscape irrigation. The projected recycled water volumes in Table 6-4 for agricultural and landscape irrigation are based on this baseline 2016 demand plus the planned methods to expand future recycled water use (see Table 6-6).

Application materials have been received by the City for a proposed South Napa Industrial Project. The project’s annual recycled water demand is estimated to be a maximum of 82 AFY.

This project is not accounted for in Table 6-6. The projected recycled water use for this project will be revisited during preparation of the 2025 UWMP when more information about this project, such as planned implementation year, is available.

6.6 Desalinated Water Opportunities
10631(d). Describe the opportunities for development of desalinated water, including, but not limited to, ocean water, brackish water, and groundwater, as a long-term supply.

The UWMPA requires that the UWMP address the opportunities for development of desalinated water, including ocean water, brackish water, and brackish groundwater.

At the present time, the City does not foresee any opportunities for the production of desalinated water. However, the City may pursue purchase of desalinated water if the supply became available through regional development.

6.7 Exchanges or Transfers
10631(d). Describe the opportunities for exchanges or transfers of water on a short-term or longterm basis.

The UWMPA requires the UWMP to address the opportunities for development of short or longterm transfer or exchange opportunities.

6.7.1 Exchanges
Water exchanges entail water being delivered by one water user to another water user, with the receiving water user providing water in return at a specified time or when the conditions of the parties' agreements are met.

The City does not have any existing or planned water exchanges. The City will continue to consider potential exchange opportunities.

6.7.2 Transfers
Water transfers entail a temporary or long-term change in the point of diversion, place of use, or purpose of use due to a transfer, sale, lease, or exchange of water or water rights.

The City does not have any existing or planned water transfers. The City will continue to consider potential transfer opportunities (such as one-time transfers from farmers who fallow fields and auction off their water).

6.7.3 Emergency Interties
The City does not have any emergency interties in which transfers of water can be made.

The City receives Vallejo Treated Water via an intertie connection (see Section 6.1.2.2).

6.8 Future Water Projects
10631(f)… The urban water supplier shall include a detailed description of expected future projects and programs that the urban water supplier may implement to increase the amount of the water supply available to the urban water supplier in normal and single dry water years and for a period of drought lasting five consecutive water years. The description shall identify specific projects and include a description of the increase in water supply that is expected to be available from each project. The description shall include an estimate with regard to the implementation timeline for each project or program.

The UWMPA requires that suppliers describe water supply projects and programs that may be undertaken to meet the projected water demands.

2020 URBAN WATER MANGEMENT PLAN | CITY OF AMERICAN CANYON REVISED DRAFT | AUGUST 2022 | 6-11
As described previously, the City is 100 percent reliant on purchased or imported water for its potable water supply. In order to diversify its water sources and improve local control over the water supply, the City has been exploring various long-term water supply options based on the following evaluation criteria:
• Institutional: Is it within the City’s operational authority? • Technical: Can it be designed, operated, and maintained? • Capacity: Will it meet anticipated demands now and in the future? • Schedule: Can it be designed, built, and permitted in time to meet the City’s requirements?
• Sustainability: Does it provide uninterrupted service without significant impacts? • Affordability: Can it be built and maintained at a reasonable cost? • Environmental: Is it consistent with local, state, and federal environmental regulations? • Quality: Is the water quality satisfactory and reliable? The City Council reviewed and discussed a preliminary list of long-term water supply options.

Based on the criteria above, the City selected three options for further evaluation, including surface water storage at Lake Curry, groundwater production wells outside of City limits, and potable reuse of recycled water. Specific projects or programs have not been selected for implementation; therefore, Table 6-7 has been left blank.

6.10 Climate Change Impacts to Supplies
The CWC requires that suppliers consider climate change in their water supply analysis. The potential water supply effects related to climate change are discussed briefly in this section.

Because the City is 100 percent reliant on purchased or imported water for its potable water supply, the effects of climate change are best summarized by considering the effects of the region as a whole. The City has continued to participate in regional climate change studies, such as, the San Francisco Bay Area Integrated Regional Water Management Plan (IRWMP) (2019) that assess potential long-term impacts of climate change and mitigation and adaption strategizes. According to the IRWMP, climate change is expected to increase water supply variability and affect regional imported water supplies as follows:
• Total precipitation is expected to decrease in the Sierra Nevada sources. • Snow pack projected to decrease from less storage in the mountains. • Precipitation projected to shift toward more rain and less snow. • Timing of runoff is expected to shift to earlier in the year, affecting reservoir storage and hydropower generation, especially in the spring and summer months. • Sea-level rise may impact Delta water deliveries.

As scientific understanding of climate change continues to advance, the nature of these impacts and the impact on water supply availability and reliability will be thoroughly studied to identify proper mitigation and adaptation strategies.

One additional consideration for the City is the impact of wildfires on water quality. The wildfire season is typically followed by the rainy season and sometimes heavy precipitation, leading to high levels of sediment in runoff that can severely degrade water quality, such as the increase in turbidity levels. In addition, Per- and polyfluoroalkyl substances (PFAS) is also an emerging contaminant that can be found in firefighting foam that can stay and spread in the environment for decades and become a major contributor to drinking water contamination.

increasing frequency of wildfires and atmospheric rivers across California, changes in treatment operations and/or treatment processes may be necessary to reliably treat and maintain water service to customers experiencing back-to-back impacts.

Additional details related to climate change data that has been collected using the Cal-Adapt tool are included in Chapter 3.

6.11 Energy Intensity
The 2020 UWMP guidebook requests that water suppliers provide information on the energy required to produce and distribute their water supply. Water energy intensity is the total amount of energy on a per acre-foot basis associated with water management processes occurring within the City’s operational control. The City has selected to report its energy intensity using the total utility approach Option B. In 2020, the City produced 2,550 AF of treated water entering the distribution system within its service area. The kilowatt hours (kWh) of energy needed across the City’s potable water system was 313,587 kWh. The energy intensity analysis is located in Appendix D. The City’s 2020 energy intensity is estimated at 123 kWh/AF (377 kWh/MG). 563

WATER SERVICE RELIABILITY AND DROUGHT

RISK ASSESSMENT
The UWMPA requires that the UWMP address the reliability of the agency’s water supplies. This includes supplies that are vulnerable to seasonal or climatic variations. In addition, an analysis must be included to address supply availability in a single-dry year and in a five-consecutive-year drought.
10635 (a) Every urban water supplier shall include, as part of its urban water management plan, an assessment of the reliability of its water service to its customers during normal, dry, and multiple dry water years. This water supply and demand assessment shall compare the total water supply sources available to the water supplier with the long-term total projected water use over the next 20 years, in five-year increments, for a normal water year, a single dry water year, and a drought lasting five consecutive water years. The water service reliability assessment shall be based upon the information compiled pursuant to Section 10631, including available data from state, regional, or local agency population projections within the service area of the urban water supplier.

7.1 Introduction
The City water supply is purchased or imported water sources, mainly SWP water (from the Delta) purchased from the Napa County FCWCD and from the City of Vallejo. Refer to Appendix A for the City’s demonstration of reduced Delta reliance.

The following factors affect water supply reliability and may pose an opportunity for inconsistency in supply.
• Legal: The SWP contract expires in 2035 with provisions for extensions. The agreement with Vallejo does not have an expiration.
• Environmental: The United States Fish and Wildlife Service (USFWS) and the National Marine Fisheries Service (NMFS) have operational rules that limit exports from the Delta for protection of several fish species per the Endangered Species Act. • Water Quality: The SWRCB has established salinity and other water quality objectives that can limit exports from the Delta.
• Climatic: Drought conditions can limit exports from the Delta. 564
CITY OF AMERICAN CANYON | 2020 URBAN WATER MANGEMENT PLAN 7-2 | AUGUST 2022 | REVISED DRAFT

7.2 Constraints of Water Sources
10631 (b)(1) A detailed discussion of anticipated supply availability under a normal water year, single dry year, and droughts lasting at least five years, as well as more frequent and severe periods of drought, as described in the drought risk assessment. For each source of water supply, consider any information pertinent to the reliability analysis conducted pursuant to Section 10635, including changes in supply due to climate change.

There are two aspects of supply reliability that can be considered. The first relates to immediate service needs and is primarily a function of the availability and adequacy of the supply facilities.

The second aspect is climate-related and involves the availability of water during mild or severe drought periods.

There are a variety of factors that can affect water supply reliability. The factors that might result in supply reliability issues include water quality and climatic changes.

7.2.1 Water Supply Quality
The UWMPA requires that the UWMP include a discussion of water quality impacts on the reliability of an agency’s water supplies. As indicated in Section 7.1, water quality may effect Delta supply reliability.

The City’s drinking water meets all applicable water quality regulations. The Annual Consumer Confidence Report (CCR) for the City’s service area in year 2020 can be found in Appendix E.

7.2.2 Climate Change
Climate change is likely to add uncertainties to supply planning and future supply availability.

The severe and prolonged drought that began in 2012 has been a test of the City's ability to prepare for, and adapt to, the effects of climate change. Considering reductions in per capita use and projected demands, the City continues to balance a cautious optimism with a long-term strategy for sustainable sources of supply.

As stated in Chapter 4, the altered climate patterns in California creating hotter days and longer heat waves will increase customer water use and evaporative water losses. Extended drought periods are expected to become both more frequent, and more severe, which could lead to reduced rainfall and snowpack. Higher temperatures and decreased precipitation will result in drought, making wildfires more frequent, more severe, and harder to fight with less water supplies. Wildfires, followed by flooding, mean more landslides and mudslides, further impacting water supply reliability. Creating defensible space as well as slope stabilization and erosion prevention near critical infrastructure will be important for preserving supplies.

Efficient use of water is paramount in the City’s effort to adapt to climate change. Technology and equipment to appropriately monitor and manage water supplies will be critical. Ensuring that pipes are appropriately sized and upgraded to minimize water loss is equally important.

Redundancy in source of supply will provide operational flexibility in the event supplies are interrupted by fire, floods, earthquakes, or drought. Climate change effects such as drought, wildfire, and temperature fluctuations may all contribute to a degradation of water quality over time.

2020 URBAN WATER MANGEMENT PLAN | CITY OF AMERICAN CANYON REVISED DRAFT | AUGUST 2022 | 7-3

7.2.3 Potential Alternative Sources
The City also uses other supplemental imported water sources as described in Section 6.1.3. The availability of these supplemental water supplies varies from year-to-year; therefore, supplemental water supplies have not been included in this water supply reliability assessment.

In order to diversify its water sources and improve local control over the water supply, the City has been exploring various long-term water supply options as described in Section 6.8.

7.3 Water Supply Reliability by Type of Year
This section considers the City’s water supply reliability during three water scenarios: average year, single-dry year, and five-consecutive-year drought. An average year is also referred to as a "normal" year.

These scenarios are defined as follows:
• Average Year: A year, or an averaged range of years, that most closely represents the average water supply available to the City. Generally, a year in the historical sequence that most closely represents median runoff levels and patterns. It is defined as the median runoff over the previous 30 years or more. This median is recalculated every 10 years.
• Single-Dry Year: The year that represents the lowest water supply available to the City.

Generally considered to be the lowest annual runoff for a watershed since the water-year beginning in 1903. Suppliers should determine this for each watershed from which they receive supplies.
• Five-Consecutive-Year Drought: The period that represents the driest five-year historical sequence for the City. Generally considered to be the lowest average runoff for a five-consecutive-year period for a watershed since 1903.

7.3.1 Basis of Water Year Data
Table 7-1 contains the water supply available for each of the water year types, as a percentage of the average water year, but the water type years have not been included. The volume available for each year type are based on the following assumptions:
• “Table A” Allotment: Assumed to be 56 percent, 5 percent, and 27 percent of the full contracted volume (5,200 AFY) for average, single-dry, and five-consecutive-year drought water types, respectively. The percent volume available for each water year type is based on the 1992 to 2003 average allocation (2021 Draft State Water Project Final Delivery Capability Report, DWR), 2014 allocation, and 1987 to 1992 average allocation, respectively.
• Article 21 Water: Assumed to be 568 AFY, 0 AFY, and 216 AFY for average, single-dry, and five-consecutive-year drought water types, respectively. This is based on the 2012 to 2020 average allocation, 2014 allocation, and 2012 to 2016 average allocation, respectively.
• Vallejo Permit Water: Assumed to be the full contracted volume (500 AFY) for all water year types.
566
CITY OF AMERICAN CANYON | 2020 URBAN WATER MANGEMENT PLAN 7-4 | AUGUST 2022 | REVISED DRAFT
• Vallejo Treated Water: Assumed to be full contracted volume (628.6 AFY) for average year water type and to be reduced by 20 percent for single-dry and consecutive dry year water types based on City of Vallejo’s WSCP Stage 2.
• Vallejo Emergency Water: Assumed to be full contracted volume (500 AFY) for single-dry and consecutive dry years 1 to 2, 400 AFY consecutive dry years 3 to 5, and to be 0 AFY for average year water type (based on historical past practice).

7.5 Drought Risk Assessment
10635(b) Every urban water supplier shall include, as part of its urban water management plan, a drought risk assessment for its water service to its customers as part of information considered in developing the demand management measures and water supply projects and programs to be included in the urban water management plan. The urban water supplier may conduct an interim update or updates to this drought risk assessment within the five-year cycle of its urban water management plan update. The drought risk assessment shall include each of the following…
(3) A comparison of the total water supply sources available to the water supplier with the total projected water use for the drought period. [Emphasis added] (4) Considerations of the historical drought hydrology, plausible changes on projected supplies and demands under climate change conditions, anticipated regulatory changes, and other locally applicable criteria.

CWC Section 10635(b) is a new requirement for the 2020 UWMPs where suppliers are required to prepare a DRA with descriptions of data and methods used, basis for the supply shortage conditions, determination of the reliability of sources, and a comparison of the total water supplies and uses during the drought. The DRA will be submitted every five years in addition to conducting an annual water supply and demand assessment. Evaluation for the DRA is based on the five dry years with consideration of climate changes, regulations, and other local criteria. In the event of stressed hydrologic conditions, suppliers will consider management of their water supplies in relation to customer usage, identify potential system vulnerabilities, and provide explanations of assumptions and decisions on which the analysis was based.

A summary of the City’s water supply DRA from 2021 through 2025 is summarized in Table 7-5.

The total water use reflects unconstrained demand without reduction measures. The supplies are based on the following conservative assumptions:
• “Table A” Allotment: Assumed to be 5 percent, 5 percent, 22 percent, 25 percent, and 27 percent of the full contracted volume (5,200 AFY) for 2021 through 2025. The percent volume available is based on the single dry year allocation of 5 percent and the 4-year drought allocation of 22 percent in the 2021 Draft State Water Project Final Delivery Capability Report, DWR.
• Article 21 Water: Assumed to be 242 AFY the first year and then unavailable the remaining years.
• Vallejo Permit Water: Assumed to be the full contracted volume (500 AFY) for all years. • Vallejo Treated Water: Assumed to be reduced by 20 percent for single-dry and consecutive dry years based on City of Vallejo’s WSCP Stage 2. • Vallejo Emergency Water: Assumed to be full contracted volume (500 AFY) for 2021 and 2022 and then 400 AFY for 2023 through 2025.

As shown, in Table 7-5, the City anticipates it can supply all its water demands by purchasing supplemental imported water through existing agreements through the planning horizon (2045) for all water year scenarios. Use reduction savings are not quantified in Table 7-5 (refer to Table 8-3).

Chapter 8

WATER SHORTAGE CONTINGENCY PLAN
In response to the severe drought of 2012-2016, new legislation in 2018 created a WSCP mandate replacing the water shortage contingency analysis under former law. The new requirements are more prescriptive to have consistency throughout California. The City Municipal Code Water Conservation Plan Chapter 13.14, included in Appendix F, serves as the City’s WSCP and may be amended as needed without amending this 2020 UWMP.

In the event any provision of this Chapter or the Water Conservation Plan (Appendix F) conflicts or overlaps with any mandatory State regulation related to water conservation, the most stringent shall apply.

8.1 WSCP Overview
The City’s WSCP details the stages of actions to be taken during a reduction in available water supply. These actions are broken up based upon six possible stages of water shortage.

Reductions in supply are most frequently associated with drought, but could also be the result of flooding, major fire emergencies, earthquakes, regional power outages, water contamination, and any other situation that could impact the City’s water supply.

The goal of a WSCP is to have a procedure for managing and mitigating shortages allowing the City to respond in an efficient and timely manner. Water shortage response actions include demand reduction, supply augmentation, operational changes, and mandatory prohibitions to address shortage levels. The following sections summarize the City’s water shortage stages and the measures employed during each stage, as outlined in the WSCP.

8.2 Stages of Action
The stages of action in response to water supply shortages, including greater than 50 percent reduction in water supply are summarized in Table 8-1. Detailed descriptions of each stage of action are included in the Water Conservation Plan (Appendix F). 574
CITY OF AMERICAN CANYON | 2020 URBAN WATER MANGEMENT PLAN 8-2 | AUGUST 2022 | REVISED DRAFT
Table 8-1: Water Shortage Contingency Plan Levels

8.3 Demand Reduction
Table 8-2 contains demand reduction actions and the water shortage stage when they are enacted. These prohibitions are detailed in the Water Conservation Plan (Appendix F).

Additionally, the City Municipal Code contains the Water Waste Prohibitions Ordinance (Section 13.14.060) (see Appendix F). This Water Waste Prohibitions Ordinance is in place at all times and is not dependent upon a water shortage for implementation.

Table 8-3: Supply Augmentation and Other Actions

8.5 Annual Water Supply and Demand Assessment Procedures The annual water supply and demand assessment identifies key data and methods for determining the supply reliability each year. The annual assessment is due to DWR on or before July 1 of each year, as required by CWC Section 10632.1. The assessment assumes the year following the planning calendar year is a dry year.

The annual supply and demand assessment will include:
• Anticipated shortage.
• Triggered shortage response actions.
• Compliance and enforcement actions.
• Communication actions.
• Review of assets.

8.5.1 Timeline
The timeline for the annual supply and demand assessment is listed below and is subject to change.
• Preparation of draft supply and demand analysis – February. • Submit and present assessment to City Manager – March. • Update and finalize assessment – April.
• Receive City Manager approval – May or June.
• Annual supply and demand assessment – Due to DWR July 1.

8.5.2 Decision-Making Process
The steps in the decision-making process that the City will use each year to determine and subsequently report to the state are listed below.

1. Determine supply available, infrastructure constraints, and expected demand.

2. Compare supply and demand and decide on the water supply reliability for the current year and one dry year.

3. Present the findings and recommendations of the Annual Assessment Report to the City Manager.

4. Prepare and submit the Annual Assessment Report to the state.

5. Determine the shortage levels and other conservation matters, including but not limited to any restrictions in the number of new service connections allowed annually for any or all portions of the City service area.

6. Maintenance and Utilities Director or a designated representative implements the provisions of the WSCP.

8.5.3 Key Data and Methodologies
The key data inputs and assessment methodology used to evaluate the City’s water supply reliability for the current year and one dry year, include the following:
• Current year unconstrained demand, considering weather, growth, building permit trends, and other influencing factors, such as policies to manage current supplies to meet demand objectives in future years, as applicable.
• Current year available supply, considering hydrological and regulatory conditions in the current year and one dry year. The annual supply and demand assessment may consider more than one dry year solely at the discretion of the City. • Existing infrastructure capabilities and plausible constraints. • A defined set of locally applicable evaluation criteria that are consistently relied upon for each annual water supply and demand assessment.
• A description and quantification of each source of water supply. • The California Drought Monitor.
• Precipitation on a calendar and weather year basis.
• Any potential State or regional actions related to drought and water use restrictions.

8.5.3.1 Water Supply
The annual assessment will evaluate the current year available and one subsequent dry year. The available water supplies for the City shall be quantified each year by summing the available water supplies. Potential production constraints, hydrological, and regulatory conditions will be considered.

8.5.3.2 Unconstrained Customer Demand
Water demand/consumption for the previous year shall be quantified by summing the meter usage of each customer class for the previous year. Customer water demands shall be projected for the upcoming year based on the previous year’s water consumption and the projected population growth.

8.5.3.3 Planned Water Use for Current Year Considering Dry Subsequent Year The planned water use for the current year is not impacted by an anticipated subsequent dry year. When SWP or Vallejo supplies are reduced, the City can purchase supplemental imported water sources.

8.5.3.4 Infrastructure Considerations
Infrastructure projects anticipated for the upcoming year that could impact water supply will be evaluated for the timeframe the projects will impact supply. The available water supply will be increased or reduced accordingly for each month.
578
CITY OF AMERICAN CANYON | 2020 URBAN WATER MANGEMENT PLAN 8-6 | AUGUST 2022 | REVISED DRAFT

8.5.3.5 Evaluation Criteria
Evaluation of the appropriate shortage level will include, but not be limited to, the following considerations:
• Current and recent trends in Delta levels.
• Other hydrological or other local conditions indicative of water supply available. • The previous winter’s precipitation.
• The previous year’s water demand.
• Current and anticipated demand for water by City customers. • Current and anticipated supply of City water sources. • Damage to the City’s water system.
• Predicted weather patterns.
• Water content of the snowpack.
• Climate change impacts.
• California Drought Monitor.
• Current or pending state and regional water use efficiency or drought related actions.

If the available water supply is greater than the anticipated customer demand for the upcoming year, then the City does not need to take any further action. If the anticipated customer demand for the upcoming year is greater than the available water supplies, or that additional conditions exist (such as a State declared drought emergency), the City can initiate water conservation actions as detailed in the WSCP.

8.5.3.6 Triggering Mechanisms for Shortage Levels
The triggering mechanisms to use as guidelines for the shortage levels include:
• System malfunction resulting in up to the percent shortage of a level or catastrophic interruption of water supplies.
• City or state declaration due to drought.
• Federal, state, or local disaster declaration that may impact water supplies. • City determination.
• Unplanned City water system maintenance.

The City may impose any of the shortage levels based upon facts and circumstances which may not have been otherwise anticipated in this chapter or WSCP.

8.6 Catastrophic Supply Intervention
The UWMPA requires that the City develop stages of action to be undertaken during a catastrophic interruption of water supply or the City’s water treatment facilities that could include flooding, major fire emergencies, regional power outage, an earthquake, water contamination, and acts of sabotage. In response to these possibilities, the City developed an Emergency Response Plan (ERP), which identifies the following goals:
• Rapidly restoring water service after an emergency.
• Ensuring adequate water supply for fire suppression.
• Minimizing water system damage.
• Minimizing impact and loss to customers.
579
2020 URBAN WATER MANGEMENT PLAN | CITY OF AMERICAN CANYON REVISED DRAFT | AUGUST 2022 | 8-7
• Minimizing negative impacts on public health and employee safety. • Providing emergency public information concerning customer service.

The ERP includes emergency planning process and water system information, including mutual aid agreements, emergency resources, emergency water supply calculations, and information on alternate water supplies. The ERP also contains emergency response chain-of-command information, concepts of operation, response and notification procedures, water quality sampling procedures, emergency response training, and action plans.

8.7 Hazard Mitigation Plan
The City is located in the seismically active San Francisco Bay region. The City’s main water transmission main is located less than a half mile from the West Napa Fault; however, all components of the City’s water system are vulnerable to seismic activity.

Napa County’s Multi-Jurisdictional Hazard Mitigation Plan is available for review at https://mitigatehazards.com/napa-county-mjhmp/documents/. The Hazard Mitigation Plan may be updated at any time. The most recent Hazard Mitigation Plan shall apply to the current WSCP.

8.8 Revenue and Expenditure Impacts
The City is fully metered and City customers are billed volumetrically. Therefore, the City may experience a decrease in revenue with reduced water sales during a water shortage. Although the variable costs of supplying water will be reduced as water usage decreases, the fixed costs will remain constant. The variable costs are linked to the purchase of imported water. The fixed costs include plant operations, salaries, debt service, capital projects, and other similar expenses.

Additional costs during water shortage situations could be associated with increased monitoring, efficiency incentives, and outreach, namely due to an increase in the hours required to monitor customer accounts and enforce reduction actions. The additional costs associated with this effort, however, are not expected to significantly impact revenues and expenditures.

To overcome a reduction in revenue due to a water shortage the City could adjust the water rates or develop a reserve fund.

8.8.1 Drought Rate Structures and Surcharges
Refer to the Water Conservation Plan Chapter 13.14 (Appendix F) for drought surcharges rates.

8.8.2 Use of Financial Reserves
The City has funding reserves established that can be utilized for a financially qualifying event, such as providing for the continued operation of the water system in the event of a decline in water service revenue.

8.8.3 Other Measures
The City will consider postponement of capital improvements and operational measures to temporarily reduce power and chemical costs as a means to overcome impacts from water shortage contingency planning to revenues and expenditures. 580
CITY OF AMERICAN CANYON | 2020 URBAN WATER MANGEMENT PLAN 8-8 | AUGUST 2022 | REVISED DRAFT

8.9 Monitoring and Reporting
The City is fully metered and City customers are billed volumetrically. The City uses these meters to monitor City-wide use, individual customer use, and track actual reductions in water use. By periodic review of customer water use, the City is able to track the effectiveness of the shortage level reduction actions, educate customers regarding water use, and also identify leaks and other areas where additional conservation may be possible.

Monitoring will be used to ensure appropriate data is collected, tracked, and analyzed for purposes of determining:
• Customer compliance.
• Effectiveness of reduction actions.
• Potential leaks in the distribution system.
• Accurate monthly demand data for the annual supply and demand assessment.

Monitoring and reporting key water use metrics is fundamental to water supply planning and management and will be a critical part of the annual supply and demand assessment. Monitoring is also essential to ensure that the shortage level response actions achieve their intended water use reduction purposes or to determine if improvements or new actions are needed. Monitoring for customer compliance tracking is useful in enforcement actions. It should be noted that timing, frequency, and metrics will likely be variable, depending on the water shortage level and enforcement action logistics.

The City can compare meter data with water use in prior months and during non-drought years to determine if it is achieving specific percentage goals for water consumption associated with the drought response levels. If the goals are not being met, the City can implement additional shortage response actions at any time.

8.10 WSCP Refinement Procedures
To evaluate the effectiveness of the WSCP and to ensure that procedures and practices developed under the WSCP are adequate and are being implemented properly, the City will perform audits of the program on a periodic basis, at least every 5 years in coordination with the UWMP update.

The City will perform a thorough review of monitoring and reporting program data to determine the effectiveness of the reduction actions and whether the procedures and provisions of the WSCP need to be revised. The review will compare the expected percent demand reduction against actual reductions and shortage response actions.

City staff, customers, and other interested parties may have suggested actions or procedures to refine the WSCP. The City will evaluate these on a case-by-case basis for incorporation into the WSCP.

Chapter 9

DEMAND MANAGEMENT MEASURES
The UWMPA requires that the UWMP involve a comprehensive discussion of the agency’s water conservation measures.
10631 (f)(A)… The narrative shall describe the water demand management measure that the supplier plans to implement to achieve its water use targets pursuant to Section 10608.30. (B) The narrative pursuant to this paragraph shall include descriptions of the following water demand management measures:
(i) Water waste prevention ordinances
(ii) Metering
(iii) Conservation pricing
(iv) Public education and outreach
(v) Programs to assess and manage distribution system real loss (vi) Water conservation program coordination and staffing support. (vii) Other demand management measures that have a significant impact on water use as measured in gallons per capita per day, including innovative measure, if implemented.

This chapter presents details of the DMMs contained in the UWMPA, as well as the City’s existing and planned efforts to further develop their water conservation program. The City is committed to water conservation and has implemented several policies and on-going programs that promote and encourage water conservation.

The UWMPA was amended in 2014 to streamline DMMs from 14 specific measures to 6 more general requirements and an "other" category. Brief descriptions of the City’s current and planned implementation of DMMs are included in the following sections. The UWMPA did not make any changes to the DMM requirements for the 2020 UWMP.

9.1 Water Waste Prevention Ordinances
This DMM involves adoption of an ordinance prohibiting water waste. The City Municipal Code contains the Water Waste Prohibitions Ordinance (Section 13.14.060) (see Appendix F). This Water Waste Prohibitions Ordinance is in place at all times and is not dependent upon a water shortage for implementation. See Chapter 8 and the Water Conservation Plan Chapter 13.14 (Appendix F) for detailed information on stages of action, prohibitions of end uses, and penalties.

In addition, the City Municipal Code Chapters 16.14 (Water Efficient Landscaping under Building and Construction Codes) and 19.22 (Water Efficient Landscaping under Zoning) summarize additional ongoing conservation efforts of the City (see Appendices G and H). 582
CITY OF AMERICAN CANYON | 2020 URBAN WATER MANGEMENT PLAN 9-2 | AUGUST 2022 | REVISED DRAFT

9.1.1 Implementation over the Past Five Years
The City has recorded violations over the past five years.

9.1.2 Planned Implementation
The City will continue to enforce this DMM. The effectiveness of this DMM will be evaluated by monitoring the number of warnings and offenses. If an area is determined to have excessive violations, the City could implement a specific public outreach program informing the public about the Water Waste Prohibitions Ordinance.

9.2 Metering
Installing water meters and billing for actual water use provides a strong incentive for customers to use less water and equalizes service cost for each customer to their actual use (high water users would pay a more equitable share of the system costs). Water metering can reduce exterior landscape water use and can also achieve a modest reduction in interior water use.

9.2.1 Implementation over the Past Five Years
All of the City customers are metered and are billed on a monthly basis. In addition, the City supply turnouts are also metered.

9.2.2 Planned Implementation
The best way to evaluate the effectiveness of metering is periodic review of customer water use.

The City could contact individual customers determined to have high water use.

9.3 Conservation Pricing
Water conservation is encouraged through a pricing system that rewards customers who use less water with financial incentives, while high water users are charged a higher rate. Often this is implemented through a tiered pricing system.

9.3.1 Implementation over the Past Five Years
The City has an increasing-tier water rate schedule for single-family residential use. These metered water rates consist of a fixed meter charge as well as a rate per unit (where 1 unit equals 748 gallons) based on usage (see Appendix I). Refer to the Water Conservation Plan Chapter 13.14 (Appendix F) for drought surcharges rates.

The City has an increasing-tier sewer rate schedule for single-family residential use, which consists of a flat rate based on the average monthly water use for January to March of the previous calendar year (see Appendix I). The City charges a sewer service rate for commercial customers based on a flat rate or water consumption, whichever is greater (see Appendix I).

9.3.2 Planned Implementation
Water rates are approved through fiscal year 2023. The water rates will continue to be in effect until new rates are adopted.

9.4 Public Education and Outreach
Examples for public education and outreach for water demand management can include coordination with other agencies and provision of programs promoting water conservation, speakers for the media or community groups, school education programs, public service 583
2020 URBAN WATER MANGEMENT PLAN | CITY OF AMERICAN CANYON REVISED DRAFT | AUGUST 2022 | 9-3
announcements, water conservation bill inserts, information booths at public events, websites, newsletters and newspaper articles, rebates, and daily water use comparisons on customer’s bills.

9.4.1 Implementation over the Past Five Years
The City has implemented this DMM through the provision of flyers, brochures, and information packets to customers, as well as providing bill inserts promoting water conservation and providing information on the City website.

The City also supplies free individual items for indoor conservation, including adjustable massage showerheads, shower timers, faucet aerators, toilet dye kits to detect leaks, and replacement toilet flapper valves, which are available for pick up at City Hall.

9.4.2 Planned Implementation
Public information can be one of the best tools to conserve water. The City will continue to promote water conservation.

9.5 Programs to Assess and Manage Distribution System Real Loss This DMM focuses on the water distribution system itself, and includes water audits, leak detection, and repair. The first step in a water audit is relatively straightforward, involving comparison of the amount of water produced with the amount of water delivered to customers.

The difference is termed “unaccounted water,” which includes actual losses (leaks) in the distribution system, authorized but unmetered use (e.g., hydrant flushing and firefighting), unauthorized water use, and meter error.

9.5.1 Implementation over the Past Five Years
When a complaint is lodged regarding a potential water leak, the City takes swift action to identify and repair the given leak as warranted.

9.5.2 Planned Implementation
The best way to evaluate the effectiveness of this program is to compare water production data at the WTP with water consumption from the City’s customers. To improve the effectiveness, the City should continue to review data and identify leaks for repair, perform an annual review of the AWWA audit information to determine if a full-scale system audit is warranted, and perform distribution leak detection when warranted and cost-effective.

9.6 Water Conservation Program Coordination and Staffing Support This DMM entails designating a Water Conservation Coordinator responsible for managing water conservation efforts, preparing conservation reports, promoting water conservation to agency staff, and evaluating the results of efforts. The Water Conservation Coordinator tasks may include, but are not limited to, monthly tracking of production versus consumption, enforcement of water use restrictions, and implementation of conservation programs.

9.6.1 Implementation over the Past Five Years
The City has not designated a Water Conservation Coordinator. The City’s water conservation program is a coordinated effort amongst various City departments, including, but not limited to, 584
CITY OF AMERICAN CANYON | 2020 URBAN WATER MANGEMENT PLAN 9-4 | AUGUST 2022 | REVISED DRAFT
the City Manager’s office (Administrative Department), Public Works, Parks and Recreation, and Community Development.

9.6.2 Planned Implementation
The City will continue to implement the City’s water conservation program. The City could educate community volunteers to aid the City in water conservation efforts.

9.7 Other Demand Management Measures
The City will continue to evaluate implementation of new DMMs in the future.

9.7.1 Efficiency and Rebates
For residential and commercial/industrial customers, $100 rebates are offered for replacing a toilet that uses more than 1.28 gallons per flush with a high-efficiency toilet with WaterSense label.

The City also offers rebates for replacing grass with drip-irrigated, low water-use plants, and permeable hardscape. $1 per square foot (sf) rebates are available for single-family residential (up to 750 sf) and for homeowner's association [HOA]/multi-family/commercial/institutional (up to 2,500 sf).

Notifying customers of the available rebates could improve water conservation within the City.

9.7.2 Administrative Policies
The City implemented the following policies to promote water conservation:
• Zero Water Footprint (ZWF) Policy: This policy has a goal of no loss in reliability or increase in water rates for existing water service customers due to new demand for water within the City’s water service area. Developers must ensure that all new developments offset the amount of increased potable water that will be consumed by their project on a one-to-one basis. Developers are required to minimize their demand for new potable water by using water efficient fixtures, consuming recycled water for non-potable uses when available, dual plumbing buildings, installing water wise landscaping and irrigation, and other appropriate measures. Methods for offsetting the increase in potable water consumption might include contributing to the City’s existing conservation programs, converting an existing public use of potable water to recycled water, contributing to projects that reduce potable water demand, increase capacity to produce recycled water, or expand the reclaimed water system, or acquiring water supply from another source.
• Municipal Code Chapter 13.10 New Water and Sewer Connections and Services: This Chapter limits new industrial water users within the City’s water service area to a net use of 650 gallons per acre per day (GPAD) and requires dual-plumbing with purple pipe. For use greater than 650 GPAD, offset options include, but are not limited to, retrofit of existing residences with low flow fixtures, purchase of otherwise developable land as permanent open space, or acquisition of other water supply resources as provided for by a water supply analysis that follows the ZWF methodology. • Administrative Policy 2011-01 on the Management and Allocation of Raw Water: This policy has a goal of shifting the City’s raw water customers (new and existing) from the 585
2020 URBAN WATER MANGEMENT PLAN | CITY OF AMERICAN CANYON REVISED DRAFT | AUGUST 2022 | 9-5
State Water Supply to alternative supplies (e.g., recycled water) and also provides for the development of an agricultural water conservation program. • Administrative Policy 2011-02 on the Management and Allocation of Recycled Water:

This policy has a goal of providing recycled water as a substitute for potable water as a first priority to the City’s parks and then to other users for irrigation purposes. This policy establishes a framework for allocating the recycled water resource and encouraging the development of privately-owned seasonal, recycled water storage facilities.
• Administrative Policy 2011-03 on the Implementation of ZWF Policy: This policy has a goal of assigning or shifting commercial, industrial, and new residential water demands from the SWP supply to more reliable alternate sources of water. This policy describes the manner in which the City will consider and evaluate new development proposals and provides guidance on acceptable methods for offsetting new water demands within the existing water system or bringing new water supplies to the City.

9.8 Planned Implementation to Achieve Water Use Targets The City has met their 2020 target of 162 gpcd. If the City can maintain water consumption rates, it will maintain conservation goals.

Section 1

INTRODUCTION
The Sacramento-San Joaquin Delta Reform Act of 2009 requires State and local public agencies with a “covered action” to submit a written certification of consistency to the Delta Stewardship Council as to whether the covered action is consistent with applicable policies. The City of American Canyon (City) receives supply through the State Water Project (SWP) by contract with Napa County Flood Control and Water Conservation District (FCWCD) and through an agreement with Vallejo for Delta water. Both supplies impact the Sacramento-San Joaquin Delta (Delta). Covered actions can include a multi-year water transfer, conveyance facility, or new diversion that involves transferring water through, exporting water from, or using water in the Delta. Therefore, the City is required to demonstrate consistency with Delta Plan Policy WR P1 (Reduce Reliance on the Delta Through Improved Regional Water Self-Reliance). Delta Plan Policy WR P1 identifies Urban Water Management Plans (UWMP) as the tool to demonstrate consistency with State policy to reduce reliance on the Delta for a Supplier that carries out or takes part in a covered action.

The purpose of this document is to demonstrate compliance with the Sacramento-San Joaquin Delta Reform Act of 2009 and provide an analysis of the City’s reduced reliance on the Delta and expected outcomes in accordance with State protocols. The analysis provided herein includes the WR P1 requirements needed in a water supplier’s UWMP to support a certification of consistency for covered actions. The inclusion of this document as an appendix in the 2015 and 2020 UWMPs fulfills the requirements of WR P1. Future projects under evaluation will fulfill the requirements of WR P1.

Section 2
DELTA PLAN POLICY WR P1 REQUIREMENTS
WR P1 details the requirements for a covered action to demonstrate consistency with reduced reliance on the Delta and improved regional self-reliance. WR P1 subsection (a) states that:

Water shall not be exported from, transferred through, or used in the Delta if all of the following apply:
• One or more water suppliers that would receive water as a result of the export, transfer, or use have failed to adequately contribute to reduced reliance on the Delta and improved regional self-reliance consistent with all of the requirements listed in paragraph (1) of subsection (c).
• That failure has significantly caused the need for the export, transfer, or use. • The export, transfer, or use would have a significant adverse environmental impact in the Delta.
602
CITY OF AMERICAN CANYON | DEMONSTRATION OF REDUCED DELTA RELIANCE 2 | AUGUST 2022 | REVISED DRAFT
WR P1 subsection (c)(1) further defines what adequately contributing to reduced reliance on the Delta means in terms of (a) above. Water suppliers that have done all the following are contributing to reduced reliance on the Delta and improved regional self-reliance and are therefore consistent with this policy:
• Completed a current UWMP which has been reviewed by the California Department of Water Resources (DWR) for compliance with the applicable requirements of Water Code Division 6, Parts 2.55, 2.6, and 2.8;
• Identified, evaluated, and commenced implementation, consistent with the implementation schedule set forth in the Plan, of all programs and projects included in the Plan that are locally cost effective and technically feasible which reduce reliance on the Delta; and
• Included in the Plan, commencing in 2015, the expected outcome for measurable reduction in Delta reliance and improvement in regional self-reliance. The expected outcome for measurable reduction in Delta reliance and improvement in regional selfreliance shall be reported in the Plan as the reduction in the amount of water used, or in the percentage of water used, from the Delta watershed. For the purposes of reporting, water efficiency is considered a new source of water supply, consistent with Water Code section 1011(a).

California Code of Regulations (CCR), Title 23, § 5003(c) is followed by a description of programs and projects that reduce reliance on the Delta. Programs and projects that reduce reliance could include, but are not limited to, improvements in water use efficiency, water recycling, stormwater capture and use, advanced water technologies, conjunctive use projects, local and regional water supply and storage projects, and improved regional coordination of local and regional water supply efforts.

Section 3

DEMONSTRATION OF REDUCED DELTA

RELIANCE
The approach to determine the City’s reduced Delta reliance and improved regional self-reliance is consistent with the approach detailed by the California DWR in Appendix C of their “Urban Water Management Plan Guidebook 2020” (DWR Guidebook), issued in March 2021. The data used in the reduced reliance analysis for demands and supplies is detailed below. All data represent average or normal water year conditions and were obtained from the 2020 UWMP, previously adopted UWMPs, and City records.

The data inputs used in the reduced reliance analysis include:
• Water Years:
- Baseline (2010) – The analysis uses a normal water year representation of 2010 as the baseline, which is consistent with the approach described in the DWR 603
DEMONSTRATION OF REDUCED DELTA RELIANCE | CITY OF AMERICAN CANYON REVISED DRAFT | AUGUST 2022 | 3
Guidebook. Data for the City’s 2010 baseline are taken from City records and information presented in the City’s 2015 UWMP.
- 2015 and 2020 Conditions – The actual conditions for 2015 and 2020 are based on data reported in the City’s 2015 and 2020 UWMPs, respectively. - 2025-2045 Conditions – Normal year projections for 2025 through 2045 are taken from the City’s 2020 UWMP.
• Service Area Water Demands with Water Use Efficiency Accounted For – These values reflect the City’s actual and projected water use, including potable water demands, agricultural raw water, and losses.
• Non-Potable Water Demands – These values consist of agricultural raw water that is not treated.
• Population – Population data for 2010 and 2015 are taken from previous UWMPs. The population for 2020 and projected populations are taken from the 2020 UWMP. • Water Supplies Contributing to Regional Self-Reliance:
­ Water Use Efficiency – This amount is calculated by DWR’s spreadsheet tool based on the City’s baseline demand, actual demands, and projected demands. Calculated by multiplying the reduction in per capita water demand from the baseline (2010) for a year by the actual or projected population for the same year. For example, in 2025 there would be a gain of 481 acre-feet (AF) in supply from water use efficiency. ­ Water Recycling – Reflects the actual or projected recycled water delivered to customers within the City’s drinking water service area. Recycled water contributes to regional self-reliance by reducing the demand for potable water. Note that there was no recycled water delivered within the service area in 2010. For example, in 2025 there would be a gain of 625 AF in supply from water recycling. ­ Other Programs – Distribution loss reductions are anticipated due to City programs.

The 2020 UWMP assumed a water loss of 7.5 percent of potable demands. If this was reduced to 5.0 percent, it would contribute to reduced reliance. The difference between the losses estimated at 7.5 percent and 5.0 percent are included in the table for 2025-2045. For example, in 2025 the difference between 7.5 percent and

5.0 percent losses would be a gain of 63 AF in supply.
- Other categories in the table do not currently apply to the City’s supply portfolio.

Supply options the city is evaluating include surface water storage at Lake Curry, groundwater production wells outside of City limits, and potable reuse of recycled water.
• Water Supplies from the Delta Watershed:
- The City sub-contracts with the Napa County FCWCD for imported surface water from the SWP.
- The City has an agreement with Vallejo to purchase raw and treated water. Vallejo has an appropriative water right for Delta water from the State Water Resources Control Board (SWRCB) pre-dating the construction of the SWP.

Tables 1 and 2 contain demand calculations. Table 3 contains the regional self-reliance analysis and Table 4 contains the analysis of the City’s reduced Delta reliance. The tables were generated using DWR’s spreadsheet tool and fulfill the requirements of WR P1 subsection (c)(1) Paragraph C. 604
CITY OF AMERICAN CANYON | DEMONSTRATION OF REDUCED DELTA RELIANCE 4 | AUGUST 2022 | REVISED DRAFT
Section 4

EXPECTED OUTCOMES FOR REDUCED

RELIANCE ON THE DELTA
As stated in WR P1(c)(1)(C), commencing in 2015, UWMPs are required to include expected outcomes for measurable reduction in Delta reliance and improved regional self-reliance. WR P1 further states that those outcomes shall be reported in the UWMP as the reduction in the amount or percentage of water used from the Delta. The following provides a summary of the near-term (2025) and long-term (2045) expected outcomes for the City’s Delta reliance and regional self-reliance based on the assumptions described in the previous section and DWR’s analysis tool. The results show that the City is measurably reducing reliance on the Delta and improving regional self-reliance, based on the percentage of the City’s water supplies from the Delta watershed.

Expected Outcomes for Regional Self-Reliance (Table 3):
• Near-term (2025) – Normal water year regional self-reliance is expected to increase from 358 acre-feet per year (AFY) in 2015 to 1,169 AFY in 2025. This is achieved through water use efficiency, increased recycled water use, and distribution system loss reductions. • Long-term (2045) – Normal water year regional self-reliance is expected to increase from 1,169 AFY in 2025 to 2,149 AFY in 2045. This is achieved through water use efficiency, increased recycled water use, and distribution system loss reductions.

Expected Outcomes for Percent of Water Supplies from the Delta Watershed (Table 4):
• Near-term (2025) – Normal water year reliance on supplies from the Delta watershed is expected to decrease by approximately 45 percent relative to the 2010 baseline. • Long-term (2045) – Normal water year reliance on supplies from the Delta watershed is expected to decrease by approximately 6.6 percent relative to the 2010 baseline.

Section 5
NEW APPENDIX TO 2015 UWMP
The information contained in this document is also included as a new Appendix G to the City’s 2015 UWMP, consistent with WR P1 subsection (c)(1)(C) (CCR, Title 23, Section 5003). As described in Chapter 10 of its 2020 UWMP, the City followed the required public notification, public review and hearing, and adoption processes required by the Urban Water Management Planning Act. Appendix G to the City’s 2015 UWMP, the 2020 UWMP (including this Appendix), and the City Municipal Code Water Conservation Plan Chapter 13.14 were adopted by the City Council on August 16, 2022 (see Appendix K of the 2020 UWMP). 605

Subject: Notice of Preparation of the 2020 City of American Canyon Urban Water Management Plan This letter is intended to notify your agency that the City of American Canyon (City) is in process of preparing the 2020 Urban Water Management Plan (UWMP). The City is located in Napa County and supplies potable and recycled water to approximately 20,000 residents and businesses through approximately 5,600 connections.

The City’s water service area is approximately 5 square miles and includes the city limits as well as the industrial/commercial area to the north along State Highway 29, including the Napa Airport Industrial Park.

UWMPs are prepared and adopted by urban water suppliers of a certain size every five years. The UWMP is a planning document in which water suppliers evaluate and compare their water supply and reliability to their current and future water demands. A complete UWMP is necessary for the City to remain eligible for state drought water bank assistance and is a requirement of state grant and loan funding programs.

The City is encouraging participation by land use agencies, water use agencies, and other interested parties in the UWMP. The City would like to extend to your agency an opportunity to meet with us to go over the various elements of the UWMP, including assumptions about future population, future water demand, future water supplies, and upcoming water conservation programs.

Based on the City’s current schedule, we anticipate that a draft of the 2020 UWMP will be available for public review in late 2021 prior to adoption in early 2022. Your agency will receive a notification letter when the draft UWMP is available for public review.

If your agency would like to learn more about the 2020 UWMP, submit questions or comments, or provide input to the City, please contact me at (707) 647-4525 or [email protected].

The UWMP is a planning document in which water suppliers evaluate and compare their water supply and reliability to their current and future water demands. A complete UWMP is necessary for the City to remain eligible for state drought water bank assistance and is a requirement of state grant and loan funding programs.

The City is encouraging participation by land use agencies, water use agencies, and other interested parties in the UWMP. The City would like to extend to your agency an opportunity to meet with us to go over the various elements of the UWMP, including assumptions about future population, future water demand, future water supplies, and upcoming water conservation programs.

Based on the City’s current schedule, we anticipate that a draft of the 2020 UWMP will be available for public review in late 2021 prior to adoption in early 2022. Your agency will receive a notification letter when the draft UWMP is available for public review.

If your agency would like to learn more about the 2020 UWMP, submit questions or comments, or provide input to the City, please contact me at (707) 647-4525 or [email protected].

Sincerely,

CITY OF AMERICAN CANYON
