Cannabis Community Benefits DAs - Staff Report

STAFF REPORT
Meeting Date: February 11, 2025
Agency: City of Belmont
Staff Contact: Kathy Kleinbaum, Assistant City Manager
Agenda Title: Cannabis Retail Businesses Community Benefit Terms Agenda Action: Discussion & Direction
Recommendation
Provide direction on the proposed Development Agreement terms under negotiation for the retail cannabis operators under entitlement review at 1397 El Camino Real and 1538 El Camino Real, Suite C and whether to continue to support consideration of one or both retail cannabis applications.

Strategic Focus Area
Economic Development and Housing
Background
The Belmont City Council has evaluated allowing cannabis-related businesses to operate in the City since January 2021.The City Council adopted a Cannabis Retail and Distribution Overlay Zoning District (S-3) on November 28, 2023 that may be applied to properties located in the El Camino Real corridor between O’Neill Avenue and F Street. Properties within this area may apply to be rezoned to the S-3 District and can then be considered for a Cannabis Use Permit to operate a cannabis retail and distribution business.

The S-3 Overlay District allows for up to 2 cannabis retail and distribution businesses within this area, provided that they are located at least 600-feet apart and are not adjacent to any sensitive uses such as childcare facilities or schools.

The City Manager’s Office created a process to pre-qualify interested businesses prior to them applying to be rezoned to the S-3 Overlay District. The process allowed staff to vet the proposed businesses with regards to the site attributes of their location, business operations, security plans, and potential benefits to the community. In addition, it allowed the City to verify the background and qualifications of all persons associated with the proposed business. Staff from multiple city departments participated in the prequalification review process including the Police Department, City Attorney’s Office, and Community Development. Four retail cannabis businesses submitted proposals for consideration. No cannabis distribution businesses were interested in locating in Belmont at this time.

As a result of this thorough vetting process, two cannabis retail businesses were invited to go through the entitlement review process: Canna-Bel at 1397 El Camino Real and NUG at 1538 El Camino Real, Suite C. To establish a cannabis retail store, these businesses have applied to have their locations rezoned to the S-3 Overlay District, for a Conditional Use Permit (CUP), and a Cannabis Permit which requires Police Department (PD) review and approval of operational/safety plans and state licensing to ensure that these uses operate in accordance with all applicable laws. Staff have reviewed the applications for 6

Cannabis Community Benefits DAs - Staff Report
compliance with all required design standards, safety protocols, and the business operators have completed the fingerprinting and background check screening process. In addition, these two businesses meet the distance requirements for both any sensitive uses in the surrounding neighborhood and from each other.

The cannabis entitlement applications will go before the Planning Commission for recommendation and before the City Council for approvals prior to the businesses being issued a Cannabis Permit allowing them to operate. As part of the entitlement process, the City will be entering into a Development Agreement with each business to memorialize their community benefit offers. Although staff intends to bring both applications forward for review at the same time, it is at the City Council’s discretion whether to grant entitlement approvals to both locations. Staff anticipates bringing the entitlement applications to the Planning Commission in March.

Analysis
Economic Development Opportunity
Retail cannabis provides an important economic development opportunity for Belmont. Cannabis stores have the potential to provide an ongoing, stable source of revenue for the City from both sales tax and business license tax receipts. The City Council established a business license tax rate of 6% of gross receipts for cannabis retail businesses while the rate for other retailers is 0.4%. These revenues are in addition to any community benefit contribution offered by the cannabis businesses as part of their Development Agreement terms.

Currently, only a handful of cities in San Mateo County allow for retail cannabis operators which means that the local market is not yet saturated. However, there are a lot of uncertainties in the retail cannabis market and not every business that launches is ultimately successful. Staff had extensive discussions with other local communities that have operating retail cannabis storefronts and have learned that while some cannabis retailers are very successful, others are struggling or have closed. In addition, staff in other cities have said they could not have predicted in advance which businesses would ultimately end up being successful. Certain business models and retail styles may resonate better with different segments of the community.

As a result, staff recommends that the City move forward with approving both cannabis retail applications in order to diversify the City’s portfolio and provide for some contingency if one operator is ultimately not viable. Given the City's constrained tax revenue streams, it is essential to optimize revenue generation from this key source to support fiscal sustainability and economic growth to support the community’s service needs.

Cannabis Retail Businesses
The Canna-Bel dispensary will be located at 1397 El Camino, at the site of the current Sumac restaurant.

The property is a stand-alone commercial building at the corner of El Camino and the east-bound leg of Harbor Boulevard that backs up to the Caltrain railroad tracks. The business is a partnership between Benny Lau and Al El-Shawa. Al El Shawa currently operates 3 other cannabis dispensaries in San Francisco: the San Francisco Mission Cannabis Club, the Russian Hill Cannabis Club, and the Union Cannabis Club.

Cannabis Community Benefits DAs - Staff Report
The NUG dispensary will be located at 1538 El Camino Real, Suite C, at the site of the former Jenny Craig outlet. The store front is located within a small strip shopping center on the west-side of El Camino, south of the intersection of the west-bound leg of Harbor Boulevard. The ownership team for the Belmont dispensary includes Hrant Ekmekjian, and Adam Peterson and Raj Pottabathni. The NUG corporate entity and related companies control 29 commercial cannabis permits nationwide and operate 13 retail cannabis locations in California, including several in the East Bay under the NUG brand.

Development Agreement Terms
The Development Agreements with the cannabis retail businesses provide a mechanism for the City to memorialize the proposed community benefit offers and provide the ability for the City to outline specific remedies for non-payment of the proposed community benefits, business license taxes, or other applicable fees. In addition, the Development Agreements provide another lever for the City to ensure compliance with the operating requirements, including the unique security measures, related to this specialized business type. The term of the Development Agreements will be for a 10-year period with an option to renew for an additional 10 years.

The community benefit contributions provided by each business represent the individual proposals and negotiations with each ownership entity based on their unique business operational and financial models.

NUG Community Benefit Terms:
• $50,000 one-time donation to Belmont Parks and Recreation towards purchase of a mobile recreation vehicle
• On-going community benefit contribution of 1.5% of gross receipts up to $12 million revenues, then 2% of gross receipts for revenues above $12 million starting after the first year of operation.

The community benefit contribution will be distributed as follows:
o 50% directly to the City to be used for Parks and Recreation for programming, scholarships, and capital needs
o 50% to Belmont Community Foundation (BCF) with a provision that if BCF sunsets then the funds are assigned to the City
Canna-Bel Community Benefit Terms:
• On-going community benefit contribution of 1.5% of gross receipts starting after the first year of operation. The community benefit contribution will be distributed as follows:
o 30% directly to the City to be used for Parks and Recreation programming, scholarships, and capital needs
o 40% to BCF with a provision that if BCF sunsets then the funds are assigned to the City o 30% discretionary, the use of which will be determined on an annual basis by the CannaBel Community Advisory Board (made up of designated community stakeholders) In conclusion, staff seeks the Council’s feedback on the proposed Development Agreement terms for the two retail cannabis operators under entitlement review. This includes guidance on whether to proceed with consideration of one or both retail cannabis applications. The community benefit contributions offered by 8

Clear direction from the Council will allow staff to finalize the negotiations for Development Agreements that align with the City's priorities and ensure an equitable approach to community benefits and regulatory compliance.

Business License Tax Administration Services

STAFF REPORT
Meeting Date: February 11, 2025
Agency: City of Belmont
Staff Contact: Grace Castaneda, Finance Director, [email protected] Nawel Voelker, Management Analyst, [email protected] Agenda Title: Business License Tax Administration Services Agenda Action: Motion
Recommendation
Motion authorizing the City Manager to negotiate and execute a 5-year Task Order with HdL Companies for Business License Tax administration services for an amount not to exceed $625,000, subject to annual Council budget appropriation.

Strategic Focus Area
Fiscal and Organizational Sustainability
Background
Revenue, audit and recovery services are specialized in nature and require an in-depth knowledge of local and state government operations and legislation. These services ensure that the City is applying local law equitably and accurately for all individuals and entities subject to local taxation in the City of Belmont.

The City has contracted with HdL Companies (HdL) to provide a broad array of audit and revenue administration services, including business license tax administration.

In the past, the City has executed Task Orders under a Master Service Agreement with HdL on triennial basis to the City’s satisfaction. The proposed five-year term on business license tax administration will continue to provide staff with a reasonable time period to measure and ensure performance from HdL, while also securing the current fee structures as proposed.

Analysis
Based on the satisfactory service that HdL has provided, staff recommends renewing the same services for a five-year term, and that the City Manager be authorized to negotiate the Task Order agreement(s) with HdL for the required services within the approved budget. While annual Consumer Price Index (CPI) increases have been included in past for these services, staff was able to negotiate with HdL and freeze the CPI increase for the first two years of the five-year term.

The City issues over 1,500 business licenses annually. HdL currently administers the City’s business license tax program, including renewal processing, new account processing, delinquent account processing and online filing and payment posting, in addition to regular audits monitoring for tax compliance. Based on historical data, the estimated fees for business license tax services after incorporating CPI increases are approximately $100,000 to $125,000 annually. 24

Business License Tax Administration Services
If approved by Council, the contract with HdL to perform Business License Tax administration services would commence effective immediately for a five-year term expiring December 31, 2029.

Alternatives

1. With direction seek an alternative firm.

2. Take no action.

STAFF REPORT
Meeting Date: February 11, 2025
Agency: City of Belmont
Staff Contact: Grace Castaneda, Finance Director, [email protected] Agenda Title: Annual Investment Policy
Agenda Action: Motion
Recommendation
Affirm the City of Belmont Investment Policy as submitted by the Finance Director/City Treasurer.

Strategic Focus Area
Fiscal and Organizational Sustainability
Background
In past years, the State of California Government Code Section 53646 required the Treasurer to render to the Council, at a public meeting, an annual investment policy.

Analysis
The Investment Policy, as recommended, affirms the Finance Director’s/City Treasurer’s fiduciary responsibility to safeguard public assets. The policy places a high priority on insuring safety of principal first and foremost, and then ensuring that the liquidity needs for payment of City obligations are met, prior to considering yield on investments.

Alternatives

1. With direction, refer the presented Investment Policy back to the Finance Director/City Treasurer.

CITY OF BELMONT

INVESTMENT POLICY

TO: Belmont City Council
Belmont City Manager
FROM: Grace Castaneda, Finance Director/City Treasurer

RE: Annual Investment Policy
DATE: February 11, 2025

1.0 Policy:

It is the policy of the City of Belmont to invest public funds in a manner which will maximize security, followed by meeting the daily cash flow demands of the entity and then provide the highest investment return consistent with, and conforming to, all state and local statutes governing the investment of public funds.

2.0 Scope:

This investment policy applies to all investments as defined by the State of California Government Code accounted for in the City of Belmont’s Annual Comprehensive Financial Report.

3.0 Prudence:

Investments shall be made with judgment and care – under circumstances then prevailing – which persons of prudence, discretion, and intelligence exercise in the management of their own affairs, not for speculation, but for investment, considering the probable safety of their capital as well as the probable income to be derived.

3.1 The standard of prudence to be used by investment officials shall be the “prudent person” standard and shall be applied in the context of managing an overall portfolio. Investment officers acting in accordance with written procedures and the investment policy and exercising due diligence shall be relieved of personal responsibility for an individual security’s credit risk or market price changes, provided deviations from expectations are reported in a timely fashion and appropriate action is taken to control adverse developments.
30 2

4.0 Objectives:

The primary objectives, in priority order, of the City of Belmont’s investment activities shall be:

4.1 Safety: Safety of principal is the foremost objective of the investment program. Investments of the City of Belmont shall be undertaken in a manner that seeks to ensure the preservation of capital in the overall portfolio. To attain this objective, diversification is required in order that potential losses on individual securities do not exceed the income generated from the remainder of the portfolio. Funds invested with the California Local Agency Investment Fund administered by the California State Treasurer meet this requirement for diversification.

4.2 Liquidity: The City of Belmont’s investment portfolio will remain sufficiently liquid to enable the City of Belmont to meet all operating requirements as reasonably anticipated.

4.3 Return on Investments: The City of Belmont’s investment portfolio shall be designed with the objective of attaining a rate of return throughout budgetary and economic cycles, commensurate with the City of Belmont’s investment risk constraints and the cash flow characteristics of the portfolio.

5.0 Delegation of Authority:

No person may engage in an investment transaction except as provided under the terms of this policy and the procedures established by the Finance Director/City Treasurer. The Finance Director/City Treasurer shall be responsible for all investment transactions undertaken and shall establish a system of internal controls to regulate the activities of authorized personnel.

6.0 Ethics and Conflicts of Interest:

Officers and employees involved in the investment process shall refrain from personal business activity that could conflict with proper execution of the investment program, or which could impair their ability to make impartial investment decisions. Employees and investment officials shall disclose to the Belmont City Clerk any material financial interests in financial institutions that conduct business within this jurisdiction.
31 3

7.0 Reporting:

The Finance Director/City Treasurer shall provide to the City Council monthly investment reports which provide a clear picture of the status of the current investment portfolio.

Schedules in the monthly report should include the following:
- A listing of individual securities held at the end of the reporting period by authorized investment category.
- Final maturity of all investments listed.
- Coupon, discount, or earnings rate.
- Par value and market value.

8.0 Investment Policy Adoption:

The City of Belmont’s investment policy shall be accepted by the City Council.

The policy shall be reviewed annually, and any modifications made thereto must be approved by the City Council.

FEMA Pre-Disaster Mitigation Grant MOU - Staff Report

STAFF REPORT
Meeting Date: February 11, 2025
Agency: City of Belmont
Staff Contact: Brigitte Shearer, Parks and Recreation Director, [email protected] Agenda Title: MOU with the City of San Bruno for FEMA Pre-Disaster Mitigation Grant and Contracted Fuel Reduction Under FEMA Grant and CAL FIRE Fire Prevention Grant Agenda Action: Resolution
Recommendation
Adopt two resolutions: (1) authorizing the City Manager to negotiate and execute a Memorandum of Understanding (MOU) with the City of San Bruno regarding the administration of FEMA Pre-Disaster Mitigation Grant No. LPDM-PJ-09-CA-2023-003 and (2) authorizing the City Manager to negotiate and execute two agreements purchasing fuel reduction work to be reimbursed by the FEMA grant and CAL FIRE Fire Prevention Grant No. 5GG21211 for a combined amount not to exceed $403,704.

Strategic Focus Area
Public Safety
Background
In keeping with the City’s Strategic Plan initiative to "Continue with urban forestry, fire, and hazard mitigation projects," the Parks and Recreation Department has secured $697,575 in grant funding for projects including hazardous fuel reduction and education and outreach. Of these funds, $372,575 come from Federal Emergency Management Agency (FEMA) Pre-Disaster Mitigation Grant No. LPDM-PJ-09- CA-2023-003 and $325,000 come from California’s Department of Forestry and Fire Protection (CAL FIRE) Fire Prevention Grant No. 5GG21211.

Some CAL FIRE grant activities, such as developing a treatment plan and expanding the City’s residential chipping program, are already underway; however, before proceeding with any FEMA grant activities, it is necessary for the City of Belmont to enter a Memorandum of Understanding (MOU) with the City of San Bruno. The FEMA grant was jointly awarded to both cities, requiring the formalization of roles, responsibilities, and procedures for managing grant funds and associated projects.

Most of the combined grant funds (70%) are reserved for contracted fuel reduction. In 2024, under the CAL FIRE grant, Dudek, an environmental, planning, and engineering firm, conducted a comprehensive assessment of the City’s open space, recommending specific treatment strategies based on wildfire behavior and Belmont’s unique topography and biology. The resulting treatment plan was completed in 2024 and will inform forthcoming requests for proposals (RFPs) for fuel reduction work. 33

FEMA Pre-Disaster Mitigation Grant MOU - Staff Report
Analysis
MOU
The attached draft MOU proposes a framework for collaboration between the City of Belmont and the City of San Bruno in the implementation of the FEMA grant. In summary, it memorializes both cities’ understanding that each will serve as the Project Manager for all grant activities occurring within our respective jurisdictions while the City of Belmont will serve as the sole Fiscal Agent and Grant Administrator. This MOU was drafted by City of Belmont staff and at the time of writing this report, is still awaiting comments from the City of San Bruno.

Fuel Reduction RFPs
Proceeding with the contracted fuel reduction work proposed under Dudek’s treatment plan and funded by both grants will include publishing two requests for proposals (RFPs), one for each grant. In total, there is $403,704 in grant funds available ($168,704 under CAL FIRE and $235,000 under FEMA) for the fuel reduction work and staff is working closely with Dudek to define an appropriate scope of work for each.

To comply with grant terms, the City must expend the funds initially but will be fully reimbursed up to the available amount.

The contracted work will include fuel reduction along emergency access roads in Waterdog Lake and San Juan Canyon Open Spaces. In these areas, the first 25 feet from the roadway will be cleared of ladder fuels, dead trees, etc. while the second 25 feet will be treated, but to a lesser degree. Mechanical clearing with occur in some places, but due to the steep terrain, hand crews will be engaged in many areas.

City Council’s Recommended Action
To proceed with work under both grants, City staff also ask that the Council adopt two resolutions: (1) authorizing the City Manager to negotiate and execute a Memorandum of Understanding (MOU) with the City of San Bruno regarding the administration of FEMA Pre-Disaster Mitigation Grant No. LPDM-PJ09-CA-2023-003 and (2) authorizing the City Manager to negotiate and execute two agreements purchasing fuel reduction work to be reimbursed by the FEMA grant and CAL FIRE Fire Prevention Grant No. 5GG21211 for a combined amount not to exceed $403,704.

Emergency Services Council JPA - Staff Report

STAFF REPORT
Meeting Date: February 11, 2025
Agency: City of Belmont
Staff Contact: Afshin Oskoui, [email protected], 650-595-7408 Agenda Title: Revised Emergency Services Council Joint Powers Agreement (JPA) Agenda Action: Resolution
Recommendation
Approve the Second Revised and Restated Joint Exercise of Powers Agreement for the San Mateo County Operational Area Emergency Services Organization and authorize the City Manager to execute.

Strategic Focus Area
Public Safety
Background
The San Mateo County Operational Area Emergency Services Organization Authority, also known as the Emergency Services Council (ESC), brings together local governments, special districts, and other entities to coordinate emergency planning and response, including for hazardous materials. This council engages in planning with respect to all phases of the emergency management cycle: prevention, protection, response, recovery, and mitigation efforts, while also maintaining key public information systems like SMC Alert.

The ESC last revised and restated the Joint Exercise of the Powers Agreement (“JPA” or “Agreement”) on October 17, 2014. Since then, the Agreement has become outdated following significant changes within the County’s Department of Emergency Management (DEM), which now operates as a standalone agency separate from the Sheriff’s Office.

Analysis
To accurately reflect the current responsibilities of the DEM and the ESC, the ESC unanimously approved the changes to the JPA. The City of Belmont partners with ESC and DEM to receive services such as Hazmat Responses, Emergency Alert and Warning, and Training and Exercises for the whole Operational Area.

Key changes to the Agreement include:
• Standardizing nomenclature;
• Updating agreement language; and
• Clarifying and defining the roles of the ESC, the ESC Finance Committee, and the DEM.

To ensure that Belmont continues to receive these services, the City Council is requested to approve the updated JPA.

ANNEX A – COMMON TERMINOLOGY
A.01 Terminology Defined
Not all vocabulary of technical terms listed in the Agreement is used in the Agreement. In part, the terms are included as a resource to further clarify terminology utilized in documentation, field operations and/or applicable subject matter.

A.02 All-Hazards: The consideration of the full spectrum of emergencies (natural, technological, or human-caused incidents) that calls for action to protect life, property, and environment. The advantages of adopting an all-hazards approach to prepare for and respond to disasters include comprehensive planning, resource flexibility, coordination among agencies, training, and community engagement to effectively control different types of disasters to reduce or eliminate duplication of effort and cost.

A.03 California Governor’s Office of Emergency Services (Cal OES): State-level organization that functions as the central command center during major emergencies and disasters in California.

Cal OES oversees the response, direction, and coordination of state and federal resources, as well as mutual aid assets, to support diverse communities in the state.

A.04 Catastrophe: Any incident, natural or human-caused, with consequences of high rates of mass casualties, damage, or disruption severely affecting the population, infrastructure, environment, economy, national morale, and/or government functions. A catastrophic event could result in sustained impacts over a prolonged period, exceed resources normally available in the impacted area, and significantly interrupt governmental operations and emergency services to such an extent that national security could be threatened.

A.05 Community Emergency Response Team (CERT): Community-level organizations of volunteer emergency workers who can provide immediate assistance to supplement the efforts of professional responders in the event of a major disaster. CERT programs train volunteers in disaster preparedness and basic disaster response skills during disaster situations so professional responders can prioritize and allocate resources to more complex tasks. Local CERT programs are supported by the Federal Emergency Management Agency (FEMA), as well as the California Governor’s Office of Emergency Services (Cal OES).

A.06 Command: The act or directing and or controlling by virtue of explicit legal, agency or delegated authority. The term “Command” may also refer to the Incident Commander.

A.07 Emergency: Any incident, natural, technological, or human-caused, that requires responsive action to protect life, property, and environment. Under the Robert T. Stafford Disaster Relief and Emergency Assistance Act (Stafford Act), an emergency means any occasion or instance for which, in the determination of the President, federal assistance is needed to supplement state and local efforts and capabilities to save lives and to protect property and public health and safety or to lessen or avert the threat of a catastrophe in any part of the United States. 59 September 19, 2024 13
A.08 Emergency Management: A subset of incident management, the coordination and integration of all activities necessary to build, sustain and improve the capability to prepare for, protect against, respond to, recover from, or mitigate against threatened or actual natural disasters, acts of terrorism or other human-caused disasters.

A.09 Emergency Operations Center (EOC): The physical location at which the coordination of information and resources to support incident management activities normally takes place. An EOC may be a temporary facility or maybe in a more central or permanently established facility, such as at a higher level of organization within a jurisdiction.

A.10 Federal Emergency Management Agency (FEMA): Federal-level organization that coordinates the federal government's response to major disasters and emergencies, providing support and resources to state and local authorities. Its role includes managing disaster relief efforts, facilitating recovery operations, and helping communities prepare for future incidents.

A.11 Incident: An occurrence or event, natural or human-caused, which requires a response to protect life or property. Incidents can, for example, include major disasters, emergencies, terrorist attacks, terrorist threats, civil unrest, wildland and urban fires, floods, hazardous materials spills, nuclear accidents, aircraft accidents, earthquakes, hurricanes, tornadoes, tropical storms, tsunamis, war-related disasters, public health and medical emergencies, and other occurrences requiring an emergency response.

A.12 Incident Command System (ICS): A standardized on-scene emergency management construct specifically designed to provide for the adoption of an integrated organizational structure that reflects the complexity and demands of single or multiple incidents, without being hindered by jurisdictional boundaries. It is used for all kinds of emergencies and can be applied to small as well as large and complex incidents.

A.13 Local Emergency: The duly proclaimed existence of conditions of disaster or extreme peril to the safety of persons and/or property within territorial limits of a county, city and county, or city caused by such conditions as fire, flood, storm, epidemic, riot, drought, sudden and severe energy shortage, plant or animal infestation or disease, earthquake, tsunami or other conditions which are likely to be beyond the control of the services, personnel, equipment and facilities of that local political subdivision to combat.

A.14 Local Government: A county, municipality, city, town, township, local public authority, school district, special district, intrastate district, council of governments (regardless of whether the council of governments is incorporated as a nonprofit corporation under state law;) regional or interstate government entity or agency or instrumentality of a local government; an Indian tribe or authorized tribal entity, or in Alaska a Native Village or Alaska Regional Native Corporation; a rural community, unincorporated town or village or other public entity. See Section 2 (10), Homeland Security Act of 2002, P.L. 107−296, 116 Stat. 2135 (2002).

A.15 Mitigation: Activities providing a critical foundation in the effort to reduce the loss of life 60 September 19, 2024 14
and/or property from natural and/or human-caused disasters by avoiding or lessening the impact of a disaster and providing value to the public by creating safer communities. Mitigation seeks to fix the cycle of disaster damage, reconstruction, and repeated damage. These activities or actions, in most cases, will have a long-term sustained effect.

A.16 National Incident Management System (NIMS): A system that provides a proactive approach guiding government agencies at all levels, the private sector and nongovernmental organizations to work seamlessly to prepare for, prevent, respond to, recover from, and mitigate the effects of incidents, regardless of cause, size, location or complexity, to reduce the loss of life or property and harm to the environment.

A.17 National Response Framework: Document that establishes a comprehensive, national, allhazards approach to domestic incident response. It serves as a guide to enable responders at all levels of government and beyond to provide a unified national response to a disaster. It defines the key principles, roles, and structures that organize the way U.S. jurisdictions plan and respond.

A.18 Operational Area (OA): An intermediate level of the state emergency services organization, consisting of SMC and all political subdivisions within the county area. In a state of emergency, the OA shall serve as a link in the system of communications and coordination between the political subdivisions comprising the OA and the Regional Emergency Operations Center (REOC) or State Operations Center (SOC). The SMC OA mirrors the County’s geographic boundaries.

A.19 Preparedness: Actions that involve a combination of planning, resources, training, as well as exercising and organizing to build, sustain, and improve operational capabilities. Preparedness is the process of identifying the personnel, training, and equipment needed for a wide range of potential incidents, and developing jurisdiction-specific plans for delivering capabilities when needed for an incident.

A.20 Recovery: The development, coordination, and execution of service- and site-restoration plans; the reconstitution of government operations and services; individual, private-sector, nongovernmental and public-assistance programs to provide housing and to promote restoration; long-term care and treatment of affected persons; additional measures for social, political, environmental and economic restoration; evaluation of the incident to identify lessons learned; and post-incident reporting and development of initiatives to mitigate the effects of future incident.

A.21 Resources: Personnel and major items of equipment, supplies, and facilities available or potentially available for assignment to incident operations and for which status is maintained. Under the NIMS, resources are described by kind and type and may be used in operational support or supervisory capacities at an incident or an EOC.

A.22 Response: Immediate actions to save and sustain lives, protect property and the environment, and meet basic human needs. Response also includes the execution of plans and actions to support short-term recovery.
61 September 19, 2024 15
A.23 Standardized Emergency Management System (SEMS): The cornerstone of California’s emergency response system and the fundamental structure for the response phase of emergency management. SEMS is required by the California Emergency Services Act (ESA) for managing multiagency and multijurisdictional responses to emergencies in California. The system unifies all elements of California’s emergency management community into a single integrated system and standardizes key elements. SEMS incorporates the use of the ICS, California Disaster and Civil Defense Master Mutual Aid Agreement (MMAA), the OA concept, and multiagency or inter-agency coordination. State agencies and local governments are required to use SEMS to be eligible for any reimbursement of response-related costs under the state’s disaster assistance program. 62

69 STAFF REPORT
Meeting Date: February 11, 2025
Agency: City of Belmont
Staff Contact: Karen Clark, Management Analyst, [email protected] Agenda Title: Ongoing Communications Outreach and Consulting Services Agenda Action: Motion
Recommendation
Authorize the City Manager to negotiate and execute Task Order No. 3 to the Master Service Agreement with The Lew Edwards Group to provide communications outreach and consulting services in the amount of $78,000 plus a 10% contingency.

Strategic Focus Area
Fiscal and Organizational Sustainability
Background
In September 2019, as part of the strategic planning process, the City Council directed staff to develop alternatives for long-term capital financing of deferred maintenance needs, maximize existing revenue sources, and identify new revenue sources to maintain financial stability. This prompted staff to issue a Request for Qualifications (RFQ) for Opinion Research and Communications Services to gauge public interest, determine feasibility, and raise community awareness for projects meeting these goals. Projects included upgrading the Barrett Community Center, improving storm drainage infrastructure, and modernizing the business license tax structure. These projects were primarily unfunded; therefore, the City was seeking guidance on where it made sense to allocate resources to advance efforts for community consideration. Following the RFQ process, the City entered a Master Service Agreement with The Lew Edwards Group (LEG).

Analysis
Communications outreach and consulting services are desired to further 2023-2027 Strategic Plan initiatives, specifically pertaining to addressing aging City facilities and infrastructure. To complete this work, City staff request that the City Council authorize the City Manager to negotiate and execute Task Order No. 3 to the Master Service Agreement with The Lew Edwards Group in the amount of $78,000 plus a 10% contingency. Funding for January-June 2025 has already been included in the 2024-25 (current) fiscal year budget; July-December 2025 services will be incorporated into the 2025-26 proposed fiscal year budget.

Bishop Subdivision Open Space Acceptance - Staff Report

STAFF REPORT
Meeting Date: February 11, 2025
Agency: City of Belmont
Staff Contact: Tracy Scramaglia, Public Works, (650) 595-7469, [email protected] Agenda Title: Bishop Subdivision Open Space and Fire Road Acceptance Agenda Action: Resolution
Recommendation
Adopt a resolution accepting the Bishop subdivision’s street improvements and fire road as completed and compliant with the City’s approved plans, authorizing the release of subdivision improvement bond, accepting a maintenance and warranty bond for the required one-year warranty period, and accepting the dedication of open space.

Strategic Focus Area
Infrastructure and Mobility
Background
In December 2009, the Belmont City Council authorized the purchase of approximately 35 acres of undeveloped land in the San Juan Hills area, including an approximately 8.2 acres Bishop Road property.

In March 2013, the Council directed the sale of the 8.2 acres Bishop Road property, subject to certain requirements and development restrictions in the purchase documents. These requirements, which the purchaser committed to, include the preservation of approximately 6.2 acres as open space for public use and limiting development to no more than three single family residential lots on the remaining two acres.

The purchaser is also responsible for maintaining the existing fire road/ public access trail from Bishop Road to the Sugarloaf Open Space Area.

The property owner has made an irrevocable offer of dedication to the City for the open space parcel in the above-referenced purchase documents. However, the offer of dedication, a decision that rests with the City, has not been accepted and is contingent upon the developer completing all public improvements.

Before the City accepts the open space, the area of dedication is dedicated as easements for fire road access, open space, drainage, public utilities, and public access.

On April 10, 2018, the Council adopted a resolution approving the development's final subdivision map and subdivision improvement agreement. The development is a four-lot subdivision that includes three residential lots and a fourth lot consisting of 6.2 acres of permanent public open space. The developer for this project is Belmont Investment Group, LLC.

The developer has entered into subdivision improvement agreements with bonds to guarantee the completion of all public improvements related to the project. The developer is responsible for constructing 74

Bishop Subdivision Open Space Acceptance - Staff Report all off-site improvements fronting their parcels. The project also includes relocating the fire road/public access trail within the boundaries of the 6.2 acres of open space parcel, thus continuing to allow pedestrian access to the Sugarloaf Mountain/open space area.

Analysis
The developer has completed the construction of the street improvements and the relocation of the fire road. They are requesting that the City accept the improvements and release the security bonds in accordance with the terms of their Subdivision Improvement Agreement. On behalf of the City Engineer, the City's Public Works Inspectors have inspected the improvements and found them to follow the City's approved plans and specifications. The City Engineer recommends the City Council accept the improvements and release the security bonds. The 10% Maintenance and Warranty bonds will be held by the City and released following the expiration of the one-year warranty period and confirmation by the that no claims of defective improvements have been received.

At the time of parcel map approval, the City Council adopted Resolution 2018-027, directing the City Manager to determine the condition of the public improvements constructed, and make recommendations on whether the City shall accept the irrevocable offer of dedication of open space, after the expiration of a one-year warranty period. Since the public improvements were substantially completed more than a year ago, and the recent inspection determined they are in acceptable conditions, staff recommend the open space dedication can be accepted now. Staff also recommends that the City accept the improvements constructed on Bishop Road fronting the property as a part of the City's street system for maintenance.

Sanitary Sewer Master Plan - Staff Report

STAFF REPORT
Meeting Date: February 11, 2025
Agency: City of Belmont
Staff Contact: Bozhena Palatnik, Public Works, (650) 595-7463, [email protected] Agenda Title: Adoption of Updated Sanitary Sewer Master Plan Agenda Action: Motion
Recommendation
Motion to adopt the updated Sanitary Sewer Master Plan (Plan), a forward-looking document that guides the management, maintenance, and development of the City’s sewer infrastructure.

Strategic Focus Area
Infrastructure and Mobility
Background
The City of Belmont sanitary sewer system has two components: collection and treatment. The collection system ranges in age from 40 to 100 years and consists of approximately 80 miles of gravity sanitary sewer pipes and force mains, 1,500 maintenance access points/manholes (MH) and 10 lift stations. The pipes range in size from 4 to 27 inches in diameter. The City’s collection area is approximately five square miles and serves a population of about 27,000 residents, in addition to businesses and visitors. The property owners are responsible for installation, maintenance and repair of the private sewer lateral(s) connecting the property to the City’s public mains. The City is a member of Silicon Valley Clean Water (SVCW) who is responsible for the treatment and disposal of its member agency’s wastewater flows.

The City routinely conducts systematic assessment, repair, and upgrade of its sanitary sewer system including pump stations. The sewer system is divided into fifteen drainage basins and each year one or more basins have been selected for a two to four-year evaluation and rehabilitation process, consisting of inspection, design, and repair or replacement construction. The sewer system is funded as an enterprise utility fund supported by the annual sewer service charges collected on property tax bills. Since 2000, approximately half of the system has been rehabilitated and or replaced.

The City has invested significantly in sewer system maintenance and upgrades since 2000, with half of the system rehabilitated or replaced. Routine inspections, preventive cleaning, and repairs have established Belmont as a leader in minimizing sanitary sewer overflows (SSOs) and reducing inflow and infiltration (I&I).

Through a coordinated effort by the operations and engineering staff, the results of the field activities (smoke testing, root foaming, CCTV, cleaning and jetting) are routinely reviewed to identify any potential maintenance or capital replacement plan of the sewer system for repairs, replacement, and rehabilitation needs. The engineering staff evaluates the conditions of the sewer lines based on the video inspection reports, historical maintenance records, and rehabilitation history to determine the priority and type of 96

Sanitary Sewer Master Plan - Staff Report
rehabilitation of the defects using a proactive approach.

Additionally, the City routinely updates its short- and long-term capital improvement projects (CIPs) through its master plans. Staff has been implementing CIPs listed in the 2007 Sanitary Sewer Rehabilitation Master Plan and the 2010 Sewer System Capacity Analysis. The estimated cost of these CIPs per the Master Plan documents was $45.9M at that time. The vast majority of projects listed in these CIPs were completed. The four remaining major projects to be completed are the Island Park Pump Station Upgrade, Citywide Force Main Replacement project, and Notre Dame Avenue capacity improvement projects.

The City’s Sewer Pump Station Master Plan, and Force Main Master Plan were updated in the past eight years. The subject of this report, the updated Sanitary Sewer Master Plan (Plan), represents a comprehensive evaluation of the City's sewer infrastructure, offering critical insights into capacity, condition, and future needs. The Plan serves as a roadmap for CIPs and maintenance strategies to ensure the system operates efficiently and sustainably for the community's current and future needs.

The Plan identifies key projects to address infrastructure deficiencies, optimize system performance, and enhance resilience. Adoption of the Plan is a significant step in maintaining high service standards and safeguarding the health and well-being of Belmont’s residents, businesses, and the environment. This Plan improves the asset management processes using state of the art technologies for both the City of Belmont, as well as the Harbor Industrial Area, that is targeted as a planned annexation area.

The funding for the sanitary sewer CIPs and Operation and Maintenance is provided by the property related sewer usage charges, sewer connection fees for new development, and any potential development related fair share contributions.

Analysis
The updated Plan is an important milestone in our community's infrastructure development. The comprehensive analysis and planning conducted in this Plan will provide valuable insights into our sanitary sewer system, identifying areas for improvement and ensuring the safety and well-being of our existing and future residents. This process has involved rigorous data collection in Belmont, as well as in the Harbor Industrial Area, analysis of the existing system and proposed growth, and stakeholder consultations. This Plan focused on sanitary sewer capacity evaluation and condition assessment.

Key Findings and Plan Highlights

1. Capacity Evaluation
The Plan used hydraulic modeling to assess sewer system capacity under current and future conditions. Sixteen capacity improvement projects have been prioritized into short- and long-term phases to address deficiencies and accommodate growth, see Attachment A. o Notable Projects:
 Upsizing the San Juan Pump Station ($5 million, 2025-2027)  Multiple pipeline upgrades citywide to enhance flow capacity and reduce bottlenecks.

Sanitary Sewer Master Plan - Staff Report

2. Condition Assessment
The condition of the sewer system was evaluated using CCTV data. Pipes with higher risk scores were prioritized for rehabilitation or replacement, see Attachment A. o Rehabilitation methods include point repairs, partial/full lining, and replacements. o Over 100,000 feet of pipelines are planned for upgrades, targeting basins with the greatest need.

3. Preventive Maintenance and Proactive Measures
The City employs advanced technologies such as root foaming, smoke testing, geographic information system (GIS) and asset management software to identify issues early and maintain system integrity.
o Routine cleaning cycles and inspections ensure the system remains in excellent condition.

Capital Improvement Program Overview
The CIP is based on a detailed capacity evaluation and condition assessment as described above to prioritize upgrades and expansions. The key goals are to address current deficiencies, accommodate future development, and maintain reliable service. Cost estimates incorporate a 5% escalation factor to account for inflation over the life of the program.

Funding Sources
• Wastewater Enterprise Fund: Primarily supports the CIP implementation. • Connection Fees: Paid by new developments to offset costs related to capacity increases in the system.

Project Prioritization
• Critical projects will be scheduled in the early years (2024–2029) to address immediate needs. • Project schedules are adjustable based on operating conditions and funding availability.

CIP Phases and Costs
The program is divided into three phases:

Phase 1: 2024–2029
• Focus: Capacity improvements, addressing condition-related issues, and lift station upgrades. • Total Cost: $35,948,000
o Capacity-Related Improvements: $11,803,460 (Gravity Mains & Manholes) o Condition-Related Improvements: $24,144,484 (Gravity Mains, Manholes, Lift Stations, Force Mains, and Others)

Executive Summary
This Sanitary Sewer Master Plan Update (Master Plan) presents an evaluation of the City of Belmont (City)’s wastewater collection system under existing and future conditions, and recommendations for a 16-year Capital Improvement Program (CIP) based on findings from capacity evaluation and condition assessment studies. This Master Plan is a tool to help the City proactively make decisions on implementing and budgeting for CIP projects to provide reliable and resilient sewer services to its existing and future customers. This Master Plan has a 20-year planning horizon till year 2043.

Existing Wastewater Collection System
The City’s sewer service area encompasses approximately 4.6 square miles (sq. mi.) serving a population of approximately 28,335.1
The City’s wastewater collection system is divided into 15 sewer basins with approximately 80 miles of gravity mains, 10 lift stations, and approximately 3.4 miles of force mains. Under current condition, the majority of the City’s wastewater flows are carried by two parallel trunk sewer lines along Ralston Ave, herein referred to as “Ralston Trunk Lines”, and discharged into the Belmont Pump Station (BPS) that is owned and operated by Silicon Valley Clean Water (SVCW), and subsequently treated at the SVCW Wastewater Treatment Plant (WWTP). A small portion of wastewater flows are discharged into the wastewater collection systems of the City of San Mateo (San Mateo) and a small portion of wastewater flows are flowing from and to the City of San Carlos (San Carlos). SVCW recently completed the construction of Belmont Gravity Pipeline (BGP) project and is planning to demolish the BPS. The City’s wastewater will be discharged into BGP and carried to the San Carlos Pump Station by gravity once BGP is in service.

The City has also planned to annex a small collection system south of the City limit called the Harbor Industrial Sewer Maintenance District (HISMD) that is in the unincorporated part of San Mateo County, and is currently owned and operated by the County.

Wastewater Flows
Based on the historical BPS influent data, water consumption data, and temporary flow monitoring data, the City’s existing average dry weather flow (ADWF) is estimated to be 1.44 million gallons per day (mgd) with 1.38 mgd discharged into the BPS, 0.017 mgd discharged into San Mateo’s wastewater collection system, and 0.036 mgd discharged into San Carlos’s wastewater collection system. The City’s maximum dry day flow (MDDF) between 2016 and 2021 was 1.91 mgd, approximately 1.38 times the ADWF. With anticipated future developments and population growth, the City’s ADWF is projected to increase to 2.65 mgd by 2043.

The City is subject to high rainfall dependent infiltration and inflow (RDII) during storm events. A temporary flow monitoring study was performed between November 2021 and April 2022 as part of the Master Plan. During the rain event that occurred between December 12, 2021 and December 17, 2021, 1 Source: U.S. Census Bureau, 2020 Census of Population and Housing (https://www.census.gov/quickfacts/fact/table/belmontcitycalifornia/POP010220) 110

Executive Summary Page 2
observed peak flow at BPS influent was 10.92 mgd which occured on December 13, 2021, and was approximately 7.9 times the existing ADWF. Details on the City’s wastewater flow characteristics are provided in Section 5.

Capacity Evaluation
The City’s wastewater collection Geographic Information System (GIS) database has been updated as part of the Master Plan project. In addition, a field survey of approximately 200 manholes was performed as part of the Master Plan. Based on the updated GIS database, survey data, flow monitoring data, and other supporting information, the City’s hydraulic model was updated and recalibrated to reflect current flow characteristics observed in the system. System RDII responses to storm events were analyzed by sewer basin using the RTK method described in Section 6. Based on the calibrated results, Sewer Basins 8,12, and 14 have the highest RDII responses and Sewer Basin 9 has the lowest RDII responses. These RDII responses may change with the City’s on-going rehabilitation and maintenance program as rehabilitating and replacing aged and defective pipes and manholes can reduce RDII into the collection system. Therefore, a temporary flow monitoring study is recommended to be performed every three to five years as part of future model updates.

Capacity evaluation was performed using the calibrated model under existing (2023), near-term future (2028), and long-term future (2043) Peak Wet Weather Flow (PWWF) conditions. The PWWF scenarios account for a 10-year recurrence frequency, 24-hour duration storm event with a total precipitation of 3.64 inches based on the National Oceanic and Atmospheric Administration (NOAA) Atlas 14 Volume 6 Version 2 Point Precipitation Frequency Estimates at the San Mateo Station with Site ID 04-7864. Temporal distribution of the 10-year 24-hour design storm was derived based on the storm event that occurred on March 5, 2016. The design storm has a peak intensity of 0.97 inches per hour. The existing PWWF was estimated to be approximately 11.3 mgd at BPS inlet, the 2028 PWWF was estimated to be approximately 13.2 mgd discharging into BGP, and the 2043 PWWF was estimated to be approximately 16.3 mgd discharging into BGP. System capacity evaluation details are provided in Section 7.

Model results were checked against the established planning criteria. Most of the deficient pipelines identified under the 2043 PWWF condition are deficient under 2023 PWWF condition. There are 16 capacity-related gravity main improvement projects identified based on the capacity evaluation results.

Capacity-related Improvement CCIP_8 is considered a vital improvement for the City as it is an improvement proposed at the most downstream segments of the trunk lines that collect almost the entire system’s wastewater flows. CCIP_8 proposed upsizing of existing 21-inch line in Karen Rd to 27- inch, upsizing the downstream 27-inch line in Harbor Blvd to 30-inch, adding a new 27-inch parallel line crossing Hwy 101 connecting to the existing 18-inch line in Shoreway, and upsizing the 18-inch line in Shoreway bewteen the new 27-inch parallel line and the exisitng 27-inch line.

This proposed improvement will eliminate capacity deificiencies of the existing trunk lines and will accommodate wastewater flows from HISMD, so it is recommended be completed before the annexation of the HISMD wastewater collection system and is phased in the near-term (2024-2029) CIP.

San Juan Lift Station is also identified to be upsized to meet the recommended lift station capacity criteria. Proposed capacity-related projects have been prioritized into three phases: near-term (2024- 2029), intermediate-term (2029-2033), and long-term (2034-2038). 111

Condition Assessments
A desktop gravity main condition assessment was performed with the closed-circuit television (CCTV) inspection data provided by the City using InfoAsset Planner (by Autodesk). According to the inspection data, vitrified clay pipes (VCP) and lined VCP were observed to have higher structural defect scores and rating indexes than polyvinyl chloride (PVC) pipes and high-density polyethylene (HDPE) pipes.

Structural defect scores and rating indexes generally increase as pipes age. Rehabilitation actions were assigned to observed defects based on the type of defects.

In addition to evaluating the physical conditions of the pipes, a risk analysis was performed on the gravity mains based on Likelihood of Failure (LOF) criteria such as pipe structural condition, pipe age, pipe material, etc., and Consequence of Failure (COF) criteria such as pipe sizes, carried PWWF, proximity to water bodies, etc. A risk score was assigned to each pipe segment on a scale of 1 to 5.

The final rehabilitation method of a gravity main segment was determined based on a customized decision tree with additional considerations. For example, 6-inch pipelines are not good candidates for lining as it will reduce the inner diameter of the pipes and can lead to future maintenance issues. Thus, 6-inch pipelines which were determined to be fully lined based on defects were recommended to be replaced instead. Proposed rehabilitation methods for the gravity mains include CCTV inspection, cleaning/heavy cleaning/root removal, point repair, partial lining, point repair plus partial lining, investigation, and replacement. The City can perform CCTV inspection, cleaning, and heavy cleaning in-house. The City has also contracted out root removal service to some local vendors. Thus, pipelines proposed with these rehabilitation methods are not included in the CIP cost estimations. Conditionrelated improvement projects are grouped by rehabilitation methods. Pipelines with risk scores of 3 and above are included in the 16-year CIP. The City concurrently developed a pavement plan for street improvements throughout 2029 (2024-2029 Pavement Plan). This Master Plan proposed gravity main rehabilitation to align with the proposed pavement plan. Rehabilitation of pipelines in the streets proposed in the pavement plan between 2025 and 2029 are phased as near-term CIP and the remaining ones are phased as intermediate-term CIP and long-term CIP based on risk scores and locations.

Manhole assessments were not performed as part of this project scope. For CIP budgeting purposes, 30% of the manholes connected to the pipelines which are proposed to be repaired or replaced are assumed to be rehabilitated as well. Lift station (LS) and force main (FM) rehabilitation projects were identified based on previous condition assessment studies as well as interviews with City staff. Hiller LS, San Juan FM, Island Park LS and its force main, as well as the Sports Complex FM are proposed to be rehabilitated in 2024-2028, and Ralston Ranch LS is proposed to be rehabilitated in 2030-2034.

Condition assessment results are discussed in Section 8.

Capital Improvement Program (CIP)
Based on the findings from capacity evaluation and condition assessment and discussions with City staff, a recommended CIP was developed for a 16-year planning horizon that is phased in near-term CIP(2024 – 2029), intermediate-term CIP (2030-2034), and long-term CIP (2035-2039), as presented in Table ES-1. Costs estimations presented in Tables ES-1 were estimated based on unit costs developed from recent local bid results between 2018 and 2023 and the City’s adopted budget plans for 2020 to 2022 and are presented in the 2023 U.S. Dollars. Total CIP costs for near-term CIP, 112

1. Introduction
This section provides an overview of the project background, purposes of this Master Plan, and associated scope of work.

1.1. Background and Purpose
The City is located in the San Francisco Bay Area region approximately halfway between San Francisco and San Jose metros in San Mateo County (County). The City area spans approximately 4.6 square miles with a population of 28,335.2 The City’s existing sewer collection system consists of approximately 80 miles of gravity sewer pipelines, 10 lift stations, and approximately three miles of force mains. The system was first constructed in the early 1920’s.

The City’s most recent sewer master plan was completed by RMC Water and Environment and was adopted in 2007. The 2007 Sewer Master Plan (2007 SMP) did not include any capacity related improvement projects. Several studies and assessments of the sewer system were completed since then with recommendations on system improvements. The following is a timeline of the studies:
• In 2010, RBF Consulting completed a Sanitary Sewer Capacity Analysis (2010 Capacity Analysis) based on flow monitoring data, and recommended a list of improvement projects. • Between 2012 and 2016, Atlantic Consultants conducted multiple cathodic protection (CP) system testing on the San Juan FM with reports summarized their findings. • In 2015 Pure Engineering Services completed a Force Main Condition Assessment (2015 FMCA) on the City’s sanitary force mains and developed a list of prioritized capital improvement projects to rehabilitate or replace the force mains.
• In 2017, HydroScience Engineers completed a Pump Station Condition Assessment (2017 PSCA) on the City’s lift stations and developed a list of prioritized capital improvement projects to rehabilitate or replace the lift stations. In the same year, HydroScience Engineers completed the Belmont Village Development Hydraulic Modeling and Analysis (BVD Modeling and Analysis) and identified improvements needed to accommodate the proposed Belmont Village Development.
• In 2018 National Corrosion conducted CP testing of four of the City’s force mains (San Juan FM, El Camino FM, Island Parkway FM, and North Road FM) and made recommendations. • In 2020, IEC completed a Sewer Model Update and Capital Improvement Program Study (2020 Model Update and CIP Study) for the City based on a 2-year flow monitoring study conducted between 2015 and 2018. A list of capacity-related improvement projects was identified based on the model results under PWWF conditions.

Since the adoption of the 2007 SMP, the City has been conducting ongoing capital improvement and maintenance projects based on the above assessments and studies. Some of the improvement projects have been constructed while some of them have been deferred. In addition, many of the City’s 2 Source: U.S. Census Bureau, 2020 Census of Population and Housing, April 2020 115
Sanitary Sewer Master Plan Update
Introduction Page 7
gravity mains are aged, and some of the lift stations and force mains are under capacity or in poor condition, thus, they are in need of rehabilitation, replacement, or upgrade.

The primary objective of this Master Plan is to consolidate findings from this Master Plan and previous studies into one comprehensive planning document in order to provide a roadmap for planning, budgeting and implementing improvements to the City’s sewer infrastructure to accommodate future growth and provide reliable sewer service to existing as well as future customers. The City also has planned to annex the HISMD’s sewer collection system of about 60 laterals currently in an unincorporated part of San Mateo County. A separate sewer master plan was prepared concurrently for this area, and is included as Appendix A. PWWF from the HISMD post annexation improvements was accounted for under 2043 PWWF in this Master Plan. A prioritized 16-year CIP with cost estimations is developed as part of the Master Plan.

1.2. Scope of Work
This Master Plan includes the following tasks:
• Perform data review and field verifications on areas with missing/inconsistent data • Clean up and update the City’s sewer collection system GIS database with available as-built drawings, inspection reports, field verified data, and inputs from City staff • Perform temporary flow monitoring study to capture the system’s current flow characteristics for model update and tidal inflow analysis
• Update existing and future flows based on the latest flow monitoring data, water consumption data, and land use information
• Update and refine the City’s existing InfoSWMM-based sewer model using updated GIS database, survey data, and new flow data
• Review and update the City’s planning criteria based on professional manual and planning criteria used by other Bay Area agencies
• Evaluate the system under various flow conditions using the updated model and identify capacity-related issues
• Perform condition assessment for system assets based on available inspection data and previous condition assessment studies
• Develop a prioritized and phased CIP based on condition assessment results and capacity analysis results
• Develop a 2023 Sewer Master Plan Report

1.3. Authorization
The Master Plan was performed under an Architectural and Engineering Services Agreement (AESA) entered into between Infrastructure Engineering Corporation (IEC), now Ardurra, and the City of Belmont, dated February 19th, 2021.

2. Planning Area
This section provides general information on the City’s existing and future land use and population.

2.1. Study Area
The City was incorporated in October 1926 and operates under a Council-Manager form of government with a five-member City Council. The City is located in the San Mateo County, California, bounded by San Mateo and Foster City to the north, by Redwood City to the east, by San Carlos to the south, and by unincorporated County area to the west. The City encompasses approximately 4.6 square miles. A vicinity map of the City is shown in Figure 2-1. The City’s topography generally slopes downward from the eastern foothills of the Santa Cruz Mountains to the west along the flat Bay plain, ranging from sea level to almost 900 feet in elevation.

The Harbor Industrial Area (HIA) is an unincorporated area of the County south of the City limit, bounded by O’Neil Ave, Old County Rd, Belmont Creek, and US 101. Although the HIA is not within the City limit, it is within the City’s approved Sphere of Influence (SOI). Due to its location and proximity to the infrastructure and service area, the City is considering annexation. The County provides sewer services to this area and refers to this area as the Harbor Industrial Sewer Maintenance District (HISMD). As a result, HIA and HISMD are used interchangeably in this Master Plan. A sewer master plan for HIA was prepared concurrently with this Master Plan, and is included as Appendix A.

The City has a semi-arid Mediterranean climate with moderate to warm summers and mild winters.3 The average annual precipitation is 19.16 inches with 90% of the rain events occurring between October and April.

The City is one of four members of the SVCW, a Joint Powers Authority. Wastewater collected from the City is conveyed through a series of pipelines and lift stations to the SVCW WWTP for treatment and disposal.

2.2. Population
Based on the 2020 Census of Population and Housing (2020 Census) by the U.S. Census Bureau, the City has a population of 28,335 as of 2020. Based on a five-year estimate (2015-2019), the City has approximately 10,285 households with an average of 2.58 persons per household. Population forecasts from a few recently prepared planning documents were reviewed to develop population projection for this Master Plan. The City’s water service provider Mid-Peninsula Water District (MPWD) had recently adopted its 2020 Urban Water Management Plan (UWMP), which used population data from the Association of Bay Area Governments (ABAG)’s Plan Bay Area 2040 that was prepared in 2017. Plan Bay Area 2040 included city-level population forecast and estimated the City’s 2020 population as 27,405 with an estimated annual growth rate of 0.5% throughout 2040. The 2020 population estimated for the City by Plan Bay Area 2040 is approximately 3.3% less than the 2020 population from the 2020 Census.

The ABAG and the Metropolitan Transportation Commission (MTC) adopted the Plan Bay Area 2050 on October 21, 2021. It was developed on top of the Plan Bay Area 2040 and covers four key elements including housing, economy, transportation, and environment through 2050. As part of the Plan Bay Area 2050 plan, the regional growth forecast through 2050 has been revised using demographic and economic model, land use model, and travel model developed by MTC and ABAG staff. Plan Bay Area 2050 used 2015 as the plan baseline year for the regional growth forecast. Unlike Plan Bay Area 2040 which provided city-level growth forecasts on households, population, and jobs, Plan Bay Area 2050 did not include city-level growth forecasts but only county and sub-county growth forecasts on households and jobs.

The California Department of Finance (DOF) has released the county population projections from 2010 to 2060 data in July 2021. The population projections were calculated using the demographic balancing equation (Current Population = Previous Population + Births – Deaths + Net Migration) with the latest historical population, birth, death, and migration data available as of July 1, 2020. This county population projections used 2019 as the baseline year.

Notes:

1. Population data obtained from Projections 2040 by Jurisdiction as part of the Plan Bay Area 2040. (http://projections.planbayarea.org/)

2. 5-yr growth rate was estimated based on the Plan Bay Area 2040 population projection.

3. The modified population in 2020 was based on the 2020 Census.

Method 2 utilized the regional growth forecast from the Plan Bay Area 2050 and the City’s 2020 population from the 2020 Census, as shown in Table 2-2. The growth forecast including population, employment, households, and housing units have been provided from baseline year (2015) throughout 2050 in 5-year increment from the Plan Bay Area 2050. Growth forecast is only available for households and employment on a county and sub-county level for planning years 2015 and 2050. The City is within Central San Mateo County. To estimate the City’s population projection, average persons per household and the percentage of population growth with respect to the baseline year were first determined for each planning year. Then, population forecast for Central San Mateo County for 2015 and 2020 were estimated based on the projected households and the calculated average persons per household. Population growth with respect to the baseline year for Central San Mateo County for the intermittent planning years is assumed to be similar to the regional population growth pattern and is proportional to the percent of regional population growth.

Once the population is projected for the Central San Mateo County, 5-year population growth rate is determined for each planning year with respect to the previous planning year (baseline year of 2020).

The 5-year population growth rates for the Central San Mateo County are applied to the City’s 2020 population to estimate the population throughout 2050 assuming the City follows the same population growth pattern.

2.3. Land Use
The City’s land use is primarily residential and is nearly built-out. It’s 2035 General Plan (General Plan) was adopted in November 2017, which is the City’s primary guide and blueprint for developments through 2035. The City also adopted the Belmont Village Specific Plan (BVSP) in November 2017. The Housing Element 2015-2023 of the General Plan was prepared as a separate document and was adopted in May 2015. The City is working on updating its 2023-2031 Housing Element and is anticipated to adopt it by January 2024. The City has also established Zoning Ordinance as an important tool to implement the General Plan and to provide regulations and a precise guide for new developments or redevelopments. Land use classifications in the General Plan are slightly different from the Zoning Ordinance classifications. The General Plan’s land use classifications are more general than the Zoning Ordinance classifications. The City is in the process of making corrections or amendments to the mapping and zoning inconsistencies.

2.3.1. Existing Land Use
The City comprises of approximately 3,017 acres. Based on the City’s provided latest zoning GIS layer, the City has been designated into 32 zones, as summarized in Table 2-5 and shown in Figure 2-2.

2.3.2. Anticipated Future Developments
The City’s Planning Department has identified the anticipated development and redevelopment in the next 20 years. Most of the anticipated developments and redevelopments are located in the eastern side of the City, especially in the Belmont Village Planned Development Area (PDA), along El Camino Real, and east of US 101.4
Table 2-6 summarizes the anticipated developments and redevelopments over the next 20 years based on input and discussion with City’s Planning Department staff. Figure 2-3 shows the locations of the anticipated developments and redevelopments. These developments/redevelopments are either just completed and not yet fully occupied, under construction, approved for entitlement, under entitlement review, or are still conceptual. Specific development information regarding proposed dwelling units and building square footage are included if available. A few development areas have been identified with anticipated future density increase, as Projects 31, 32, and 35 in Table 2-6. A future floor area ratio (FAR) has been assumed for these areas based on the maximum FAR designated for the zones as well as input from City’s planning staff.

Anticipated future developments and redevelopments which will be connected to the HISMD sewer system are not included in Table 2-6 or shown in Figure 2-3. Details can be found in the 2023 HISMD Sanitary Sewer Master Plan (Appendix A).

3. Existing Sewer System Description
The City’s sewer collection system was constructed over a period of close to 100 years beginning in the 1920’s. The system consists of approximately 80 miles of gravity sewers ranging from 6 inches to 27 inches in sizes, 10 lift stations equipped with two to three pumps, and approximately 3.4 miles of force mains ranging from 2 to 12 inches in size. All lift stations are connected to a Supervisory Control and Data Acquisition (SCADA) System at the Corporation Yard managed by Mission Communications.

3.1.1. Geographic Information System (GIS)
The City maintains up-to-date CCTV inspection data and GIS database of its existing sewer facilities.

Based on the 2020 Model Update and CIP study, inconsistent data was found among hydraulic model, GIS records, and field observations. GIS data review and clean up has been performed as part of this Master Plan project. The City’s most recent GIS database and hydraulic model were reviewed to identify missing or inconsistent information including but not limited to pipe size, material, invert depth, network configuration, etc. These areas were corrected or updated utilizing knowledge from field staff, CCTV inspection records, as-builts, as well as field verifications. Two hundred manholes spatially spread throughout the system were selected to be field surveyed to validate the invert information from the hydraulic model and updated into GIS.

3.1.2. Sewer Basins
The City divided its service area into 15 sewer basins as part of an Inflow/Infiltration (I/I) study in the 1980s.5
The sewer basins have been updated and refined in the subsequent studies to reflect more accurate mapping of the sewer system. In this Master Plan, the sewer basins were further refined based on the updated GIS database, as shown in Figure 3-1. Most of the basins have slight boundary adjustments. Ralston Trunk Lines along Ralston Ave serve as the backbone of the system and collect flows from each basin.

3.1.3. Gravity Sewers
The City owns and operates approximately 80 miles of gravity sewer pipelines. More than half (approximately 59%) of the gravity sewer pipelines are VCP or lined VCP. Table 3-1 summarize the gravity mains by material. Figure 3-2 shows the locations of the gravity mains by material. Material information was obtained from the City’s latest sewer collection system geodatabase. Approximately 8,000 linear feet (LF) of gravity sewer were replaced or rehabilitated annually, and the gravity sewers were typically lined or replaced with plastic pipe such as Polyvinyl Chloride (PVC) or High-Density Polyethylene (HDPE) pipes.6

Gravity mains of the City’s sewer system were installed as early as in the 1920s. As shown in Table 3- 3, over half of the gravity mains were installed prior to Year 2000. The City has continuously rehabilitated or replaced its gravity mains since 1991 through its annual sewer maintenance and rehabilitation program. Gravity mains displayed by installation period are shown in Figure 3-4.

3.1.4. Lift Station and Force Main
The system consists of 10 lift stations equipped with 2 to 3 pumps at each station. Seven of the lift stations have either on-site or portable backup generators. The remaining lift stations have connections such as generator termination lugs or pin and sleeve generator receptables for portable backup generators. Table 3-4 summarizes the pump and wet well information of each lift station. Locations of the lift stations and force mains are shown in Figure 3-1. The City recently replaced and upgraded the North Road LS and its force main, and the wet well and force main of El Camino Real LS.

The system consists of approximately 3.4 miles of force mains ranging from 2 to 12 inches in size.

Force main materials include PVC, HDPE, asbestos cement (AC) pipe, cast iron pipe (CIP), and Ductile Iron Pipe (DIP). Table 3-5 summarizes the force main information. 138

3.1.5. Operation and Maintenance
The City revised its Sewer System Management Plan (SSMP) in October 2020 that details the City’s sewer system operation and maintenance efforts. The City implements an on-going inspection and rehabilitation program since the early 1990s. The program includes on-going CCTV inspection program for the gravity sewers, proactive, preventive, and corrective maintenance of the gravity sewers, rehabilitation and replacement of mains that are in poor condition, and periodic inspection and preventive maintenance for lift stations and force mains.7 The City has low Sanitary Sewer Overflows
(SSO) incidents. More details are provided in Section 8.

The City proactively cleans its entire gravity mains at least once every two to three years and preventively cleans sewers with a history of problems every three and six months. The City inspects manholes as part of the cleaning operations. The City routinely inspects the gravity sewers basin by basin utilizing its in-house CCTV crew and facilities and has inspected the gravity sewers of the entire system. The City can complete inspection of all the gravity sewers in the system once every three to four years with the current CCTV frequency. A list of known structural deficiencies determined from the inspection results is maintained and kept in order of priority by structural rating. Major defects that would result in a stoppage or overflow are immediately reported and scheduled for repair.

The maintenance crew provides emergency standby operation 24 hours a day, 7 days a week. The City summarizes all sewer related service calls and keeps them in electronic records. Approximately 8,000 linear feet of video inspection, 31,000 linear feet of line cleaning in average were performed monthly in 2020. The City contracts out for root foaming on a regular basis to reduce stoppages due to invasive roots.8
The City inspects its lift stations on a weekly basis. Inspection activities include changing fluids, pump testing, checking batteries and batteries chargers, exercising valves and standby generators, cleaning wet wells and bar screens, locks and hardware lubrication, and visual evaluation of other elements.

Inspection forms are completed by the maintenance staff following each inspection to document their findings and actions.8

4. Planning Criteria
As part of the Master Plan, the City’s planning criteria were reviewed as well as compared against those criteria used by other Bay Area Agencies and related industry standards (2nd Ed. WEF Manual of Practice no. FD-5 Gravity Sanitary Sewer Design and Construction published by the American Society of Civil Engineers (ASCE) and the Water Environment Federation (WEF). This section presents the summary of planning criteria recommended and subsequently used for hydraulic analysis, evaluation of system capacity, and sizing of capital improvements to mitigate deficiencies and accommodate future growth. A separate document, the Design Guide, details the criteria presented herein and is included as Appendix A. Comparison matrices of the planning criteria against other agencies are included as Appendix B.

4.1. Gravity Sewers
The planning criteria used to evaluate the capacity of the gravity sewers are presented in Table 4-1.

Table 4-1. Planning Criteria for Gravity Main
Design Criteria Value
For existing gravity mains 12 inches or smaller in size maximum depth of Diameter (d/D) shall not
exceed 0.7 under PWWF condition
For existing gravity mains greater than 12 inches in size maximum d/D shall not exceed 0.85 under
PWWF condition
For new gravity mains 12 inches or smaller in size
maximum d/D shall not exceed 0.5 under PWWF
condition
For new gravity mains greater than 12 inches in size
maximum d/D shall not exceed 0.75 under
PWWF condition
Minimum velocity 2 fps when flowing half full
Maximum velocity 10 fps
Minimum size for new pipe 8 inches
Manning's n 0.013
Based on the previous flow monitoring studies as well as the 2021-2022 flow monitoring study conducted for this Master Plan between November 2021 and April 2022, the City’s sewer system has significant rainfall dependent Infiltration/inflow (RDII) issues during wet seasons.9 Therefore, it is
recommended to size new gravity mains under PWWF conditions. The minimum diameter for new gravity mains is recommended to be 8 inches for maintenance purposes.

The City is largely built out and future development patterns are relatively certain. Existing City-owned sewer gravity mains may be flowing at levels above a d/D of 50% and still be operating satisfactorily. 9 Sources: 2010 Capacity Analysis prepared by RBF Consulting, 2020 Model Update and CIP Study prepared by IEC, and the 2022 Flow Monitoring Study.
143
Sanitary Sewer Master Plan Update
Planning Criteria Page 35
Therefore, the maximum d/D recommended for existing gravity mains are higher than new gravity mains to “trigger” a capacity improvement project. For new gravity mains, the remaining pipeline capacity, d/D above 50% or 75% depending on pipe size, has been reserved to handle emergency flows and provide for ventilation within the pipe.

Pipe materials, pipe size, age, structural conditions, and other factors affect the pipe roughness. For planning purposes, a manning’s n value of 0.013 is used for hydraulic analysis of the gravity mains in the City’s sewer system. This is a typical design value used by various agencies, as shown in Appendix B. Minimum velocity of gravity mains is recommended to be 2 feet per second (fps) when flowing half-full to achieve self-cleaning, and maximum velocity of gravity mains is recommended to be 10 fps to minimize scouring and erosion.

4.2. Manhole
Manholes are recommended to be installed at points of change in pipe grade, changes in pipe size or material, at intersections of where two or more sewer mains join, and accessible locations for maintenance and emergency service. The maximum spacing for gravity mains 21 inches or smaller in diameter is 300 feet and the maximum spacing for gravity mains larger than 21 inches in diameter is 400 feet. Additional details are provided in the Design Guide (Appendix B).

4.3. Lift Station and Force Main
Lift stations are recommended to be sized with firm capacity sufficient to accommodate PWWF. Firm capacity is defined as the capacity with the largest pump not in operation. This would provide a factor of safety in case a pump malfunctions and require maintenance, or miscellaneous debris, and wear and tear that may reduce pumping performance.

The Hazen-Williams “C” factor for force mains varies depending on the pipe material, age, and structural conditions. For planning purposes, a Hazen-William’s “C” factor of 130 is used for the hydraulic analysis of the force mains. Force mains are recommended to be sized to provide minimum velocity of at least 3 fps at Peak Dry Weather Flow (PDWF) condition and maximum velocities not exceeding 8 fps under PWWF condition to minimize scouring, erosion, and surge issues. 144

5. Wastewater Flow Characteristics and Projections
This section discusses the City’s wastewater flow characteristics under existing (2023) system conditions and flow projections under near-term future (2028), and long-term future (2043) conditions.

5.1. Wastewater Flow Component
Below are brief descriptions of wastewater flow terms used in this Master Plan.

5.1.1. Average Dry Wastewater Flow (ADWF)
The Average Dry Weather Flow (ADWF) includes base wastewater flow (BWF) and groundwater infiltration (GWI). BWF is domestic (or sanitary) wastewater flow from residential, commercial, institutional, and industrial wastewater. GWI is defined as groundwater entering the sewer collection system through pipe joints, cracks, and manhole walls due to structural defects or improper construction.

5.1.2. Peak Dry Weather Flow (PDWF)
Domestic sewer flows vary throughout the day due to different customer water use patterns. Peak Dry Weather Flow (PDWF) is the highest flow during a typical dry day and is determined by multiplying a peaking factor to the ADWF.

5.1.3. Peak Wet Weather Flow (PWWF)
Peak Wet Weather Flow (PWWF) is the highest flow occurred during a significant rain event and is estimated as Peak Dry Weather Flow (PDWF) plus Peak Rainfall Dependent Infiltration/Inflow (RDII).

RDII is infiltration and inflow of storm water that enters the sewer collection system in direct response to the intensity and duration of a rainfall event. Typically, peak RDII is derived from flow monitoring data collected for wet weather events.

5.2. Historical Wastewater Flow
The City’s sewer system serves approximately 97% of the City’s jurisdictional area. A small portion of the area is connected to San Carlos’s sewer system and a small portion of the area is connected to San Mateo’s sewer system. In addition, there are some sewer flows from the City of Redwood City (Redwood City) and San Carlos discharging into the City’s sewer system, as shown in Figure 5-1.

Sewer flows collected by the City’s sewer system are conveyed to the BPS10, which is owned, operated, and maintained by SVCW and are subsequently treated at the SVCW WWTP.

The City’s existing ADWF was estimated based on a few sources of data, including: 1) flow data from the flow monitoring study conducted between November 2021 and April 2022 with 22 flow monitoring sites as part of this Master Plan, hereinafter referred to as 2021-2022 flow monitoring study ; 2) flow 10 Also commonly referred to as the Shoreway pump station 145
Sanitary Sewer Master Plan Update
Wastewater Flow Characteristics and Projections Page 37 data from the 2-year flow monitoring program conducted between 2015 and 2017 as part of the 2020 Model Update and CIP study, hereinafter referred to as 2015-2017 flow monitoring study; 3) daily BPS influent flow data between 2014 and 2021 as well as 15-minute time interval BPS influent flow data for period between January 1, 2021 and April 20, 2022 provided by SVCW.

The aforementioned data was used to quantify and characterize the City’s wastewater flows for the sewer hydraulic model update as well as developing sewer generation factors for future development flow calculations. The 2021-2022 flow monitoring data and the BPS influent flow data were used as the primary source for wastewater analysis as they were the most current data set. Data from the 2015- 2017 flow monitoring study was used as an additional source to help calibrate the hydraulic model.

Wastewater flow data was checked against water consumption data. Water billing records between November 2019 and April 2020 were provided by MPWD. Average day demand (ADD) was calculated by service connection and geocoded by service addresses. More than 99% of the billing records returned with matched addresses. Remainders were manually located if possible. The geocoded water billing records were then linked to the closest parcels. Water demands with irrigation classification were assumed to not return to the sewer system.

Parcel-level ADWF were calculated by applying calibration factors to the parcel-level ADD so that the total ADWF of parcels within the same flow monitoring meter tributary area match the observed ADWF from the 2021-2022 flow monitoring data and BPS influent flow data. No flow monitoring meters measured areas that connect to the San Carlos sewer system or the San Mateo sewer system. Existing ADWF from these areas were estimated based on the water consumption data and the calibration factors used on the metered areas within the same sewer basins.

Table 5-1 summarizes the City’s historical dry weather flows (DWF) to BPS between 2016 and 2021.

Table 5-1. Historical 2016-2021 Dry Weather Flow (DWF) to Belmont Pump Station Year ADWF (mgd) Max. Dry Day Flow (mgd)
2016 1.38 1.58
2017 1.65 3.66
2018 1.31 1.58
2019 1.39 1.91
2020 1.37 1.60
2021 1.19 1.39
The City’s ADWF to BPS was estimated based on influent flow data during dry months (months without precipitation). The City’s ADWF to BPS over the past 6 years (2016-2021) was approximately 1.38 mgd. The maximum dry day flow (MDDF) over the past 6 years of 3.66 mgd occurring on June 15, 2017, was considered an outlier and not representing the City’s typical MDDF and was disregarded.

The MDDF of 1.91 mgd occurring on April 2, 2019, was considered to be the MDDF over the past 6 years, which is 1.38 times the ADWF.

Table 5-2 summarizes the City’s existing ADWF by receiving sewer systems. 146

5.3. Sewer Generation Factors
As part of this Master Plan, sewer generation factors were developed for future development flow estimation, as shown in Table 5-3. These sewer generation factors were recommended based on the 2021-2022 flow monitoring data and water billing records, as well as sewer generation factors used by neighboring agencies. Average sewer flows were determined based on dry day data and compared to the geocoded water demands. These meters collected flow data from a mix of land use types.

Residential land uses made up a great portion of the metered areas.

Sewer flow was calculated for each land use type by applying a return-to-sewer ratio (RTS) assumed for each land use type to the water demands of the corresponding area and calibrating the RTS to match the metered flow as close as possible under an iterative, trial and error process. Lower density residential land use is assumed to have lower RTS than higher density residential land use due to more outdoor water use. Likewise, Commercial and Office land use types are assumed to have higher RTS than residential land use. Irrigation water usage is assumed to have 0% RTS.

Gross acreage information was obtained from the City’s parcel GIS layer and the building square footage was estimated from the County’s building footprint GIS layer which includes footprint area and building height. An average story height of 12 feet was assumed to determine the building stories which was then multiplied by the footprint area to estimate the building square footage. Additional details of sewer generation factors calculated from sample areas are provided in Appendix D.

5. assumed a FAR of 0.5

6. based on sewer generation factors used by agencies in California.

5.4. Sewer Flow Projections
Using the sewer generation factors listed in Table 5-3, sewer flows for the future developments identified in Table 2-6 were estimated based on proposed land use types, as presented in Table 5-4.

For developments without specific proposed land use information, such as Project 31 and Project 32, sewer flows were assumed to increase proportionally to the increase in density using the FAR ratios.

Future sewer flows were projected for near-term (2028) and long-term (2043). Near-term future (2028) future flows account for developments that have been completed or are anticipated to be realized by 2028. Flows from the remaining areas are assumed to increase proportionately to the population growth to account for infill growth. Similarly, long-term (2043) future flows account for all the developments identified in Table 5-4 and flows from the remaining areas are assumed to increase proportionately to the population growth to account for infill growth. Sewer flows from the HIA area are assumed to be re-routed and discharged into the City’s collection system by 2043. The 2043 ADWF of the HIA area is projected to be 0.32 mgd. Table 5-5 summarizes the projected future sewer flows within the City’s sewer service area. Details of the projected future sewer flows within the HIA area are included in the 2023 HISMD Sanitary Sewer Master Plan (Appendix A). 150

5.5. Flow Monitoring Program
As mentioned in Section 5.2, a two-year flow monitoring program was conducted between 2015 and 2017 as part of the 2020 Model Update and CIP study, and a flow monitoring study was conducted between November 2021 and April 2022 with 22 flow monitoring sites as part of this Master Plan. The 2021-2022 flow monitoring study focused on locations with system improvements completed post the 2015-2017 flow monitoring study, flow splits in the Ralston Trunk Lines, and representative areas for institutional and commercial land uses. The flow data were reviewed for mass flow balance, that is, comparing the flows from upstream meters to downstream meters to check for flow continuity. Meters with mass flow balance issues were disregarded and not used for model calibration.

5.5.1. Temporary Flow Monitoring Sites
Table 5-6 lists the 2021-2022 flow monitoring meter locations and monitoring periods. The data was collected in 5-minute time intervals. Figure 5-2 shows the flow meter locations geographically. Figure 5-3 is the schematic diagram of the flow monitoring meters. 153

5.5.2. Flow Monitoring Results
Flow monitoring data collected from the 2021-2022 flow monitoring study was analyzed to determine observed ADWF, PDWF, and PWWF.

5.5.2.1. Rainfall Events
The City has rain gauges installed at Hiller Street LS (Hiller RG) and Naughton LS (Naughton RG).

Precipitation data from these two rain gauges were collected in 15-minute time intervals and was used to identify the flow data for dry days and wet days. Figure 5-4 shows the observed precipitation at the two rain gauges between November 15, 2021, and April 20, 2022.

Figure 5-4. Observed Rainfall Events during 2021-2022 Flow Monitoring Study

In general, precipitation observed at the Naughton RG was higher than what was observed at the Hiller RG. Between November 15, 2021, and April 20, 2022, there were two large rain events observed (with total precipitation greater than 0.5 inch), as summarized in Table 5-7.

During the 2021-2022 flow monitoring study, flow data during Event 1 had been partially captured at most meter sites and no flow data during Event 2 was captured, as shown in Table 5-7. During Event 1, the highest daily precipitation occurred on December 13, 2021, with 1.98 inch recorded at Hiller RG and

2.97 inches recorded at Naughton RG. According to the NOAA Atlas 14 Volume 6 Version 2 Point Precipitation Frequency Estimates at San Mateo Station (Site ID 04-7864), Event 1 recorded at Hiller RG was slightly larger than a 1-year 4-day storm event of 2.92 inches, and Event 1 recorded at Naughton RG was closed to a 5-year 4-day storm event of 4.99 inches.

5.5.2.2. Dry Weather Flow Data
Table 5-8 summarizes the observed ADWF and PDWF from each meter. As the data was in 5-minute time intervals, observed hourly PDWF were determined by averaging the flow data points hourly. Since the Ralston Trunk Lines are parallel trunk lines with multiple flow splits, as shown in Figure 5-3, multiple meters were reviewed in pairs to check for mass flow balance, such as Meters #6 and #7, Meters #8 and #9, and Meters #11 and #12.

comparing to the corresponding average water usage from the metered areas. The mass balance inaccuracies can be due to various factors such as meter calibration issues, device or sensor issues, or other factors that affect readings such as system transients or obstructions in the sewer system.

5.5.2.3. Wet Weather Flow Data
Table 5-9 summarizes the observed PWWF based on the available flow data. Most meters show the observed PWWF occurred on December 13, 2021, that is consistent with the precipitation data. Some meter sites showed different PWWF dates. This may be due to unusual flow events or instrumental error.

5.5.2.4. Tidal Influence
The City is situated near the eastern edge of the San Francisco Peninsula, a few miles inland from the Pacific Ocean. High infiltration and inflow (I&I) have been observed at the Island Park LS wet well and Hiller Street LS wet well that may be subject to sea level rise and tidal influence. Meter #18 was installed at the inlet of the Hiller LS wet well, Meter #25 was installed at the inlet of the Island Park LS wet well, and Meter #20 was located downstream of the Island Park FM in close proximity to the coastline. To exclude the impact of I&I due to rainfall event, minimum hourly nighttime flow observed during dry days at these meter sites were determined and flow patterns at these sites were compared with tide data to evaluate system response to tide fluctuation. Observed minimum hourly nighttime flows were assumed to be contributed by I&I at the sites. I&I rate of each meter site was estimated by dividing the observed minimum hourly flow by meter basin area. 162

The City does not have standards on maximum allowable I&I. Based on the ASCE Manual No. 60, the standards on maximum allowable I&I vary by agency. For example, the State of Oregon has an I&I allowance of less than 2,000 gpd/ac, and the Maryland Department of the Environment has an I&I allowance of 400 gpd/ac.

Based on the locations of the three meters, Meters #20 and #25 are closer to the coastline and are more likely to be subjected to tidal inflow. However, based on the flow data, observed minimum hourly flows at these two sites were minimal and observed minimum flow at Meter #18 was the highest. The I&I rate calculated for Meter #18 was below the typical I&I allowance.

In addition, level and temperature data collected from the three meters during a dry weather week were compared to the tide pattern obtained from NOAA’s Tides and Currents website at Station 9414523.11 It is assumed that when substantial tidal inflow enters the system at the metered areas, the observed flow level would increase correspondingly. Also, tidal inflow is assumed to have lower temperature than typical BWF and would reduce the wastewater flow temperature when substantial tidal inflow enters the sewer system.

None of the sites showed significant inflow changes or temperature reduction corresponding to tide level changes, as shown in Figure 5-5. Based on the available data, it is inconclusive that tidal influence occurs at the metered areas of the City’s sewer system. 11 Source: https://tidesandcurrents.noaa.gov/

5.6. Design Storm
System capacity is usually evaluated under PWWF condition, and sizing of facilities is based on PWWF. A design storm is a synthetic rainfall event used to evaluate the sewer system’s response under wet weather flow conditions. A design storm has a specific recurrence interval and rainfall duration. The selection of a design storm is a decision that balances risk of capacity deficiency during a particularly heavy rainfall event versus economic consequences of over-designing the collection system to handle flow that occurs only occasionally. Based on a review of neighboring agencies’ planning studies and management plans and discussion with City staff, a 10-year 24-hour design storm was used for hydraulic evaluation in this Master Plan. According to the NOAA Atlas 14 Volume 6 Version 2 Point Precipitation Frequency Estimates, a 10-year 24-hour storm within the City’s vicinity (Site 04- 7864) has a total precipitation of 3.64 inches. Temporal rainfall distribution of the design storm was developed based on the storm event that occurred on 3/5/2016 and has a peak intensity of 0.93 inch per hour, as shown in Figure 5-6.

Hydraulic Model Update

6. Hydraulic Model Update
The City’s sewer hydraulic model was updated and refined based on the updated GIS database, survey data, as well as flow monitoring data.

6.1. Previous Hydraulic Model
A sewer hydraulic model was developed in 2010 using H2OMap Sewer as part of the City’s 2010 Capacity Analysis. The model was converted to an InfoSWMM sewer model and was updated based on available as-built drawings, pump curves, and the 2015-2017 flow monitoring data as part of the 2020 Model Update and CIP Study. The model was calibrated to represent the observed peak flow conditions. Peak RDII was estimated from the flow monitoring data using the constant unit rate method.

That is, peak RDII was estimated as a fixed constant and was distributed evenly to the model nodes within the same flow meter tributary area.

6.2. Data Collection and Validation

6.2.1. Field Verification and GIS Update
In support of the hydraulic model update and analysis, and to provide more accurate and up-to-date maps, part of this Master Plan effort was to verify missing/inconsistent data such as invert depths, pipe size, pipe age, etc. in the existing sewer GIS database. Using available video inspection reports, asbuilts, field verified data, as well as interviews with City’s operation staff, DCSE, a subconsultant to Ardurra for this Master Plan, performed the cleanup and updates to the City’s GIS database.

Approximately 200 manholes, or about 8% of the City manholes, were surveyed in the field with the collection of manhole inverts, pipe inverts, and pipe sizes. Inverts were compared with the inverts in the existing hydraulic model to identify any discrepancies and make corrections accordingly.

6.3. Model Update
The updated GIS database and field survey data were utilized to update the City’s sewer hydraulic model, which included update and correction to network configuration, manhole and pipe inverts, and pipe sizes. As mentioned in Section 5, ADWF was calculated on a parcel level by applying multipliers to the water consumption data to match the observed ADWF from the most recent flow monitoring data and BPS influent flow data. Wastewater flows that were updated were apportioned on a manhole-by manhole basis by assigning each parcel to the closest manhole (model node).

6.4. Model Calibration
To make sure that the model accurately represents current system conditions, the model was further calibrated using the 2021-2022 flow monitoring data. Model calibration is an iterative process of comparing model prediction to actual field data and adjusting model parameters to produce model results that are within an acceptable agreement of the field measurements. The model was first calibrated for dry weather condition and then for wet weather condition for each sewer basin. Since there was no meter installed at Sewer Basins 6, 12, 13, 14, and 15 during the 2021-2022 Flow 166
