OLD BUSINESS
K. Request to Reconsider Utility Payment Requirements by Silverspot Nursery School City Manager Dennis reported that staff recommends that the Council consider Silverspot Nursery School’s request to reconsider its responsibility for water utility payments under the current lease agreement and provide direction to staff accordingly.

After Council questions, Jessica Farkas and Teacher Diana Ji asked the Council to reconsider the school’s utility payment requirements as Silverspot Nursery School is just getting back on their feet. Based on the information available at the time and prior consumption patterns, Silverspot anticipated an additional annual expense of approximately $500. However, discussions during the lease renewal period did not account for recent citywide rate increases affecting all water customers, nor for additional components reflected on utility bills, including water service fees, sewer charges, capital project assessments, and drought contingency fees. Silverspot has requested that the Council reconsider the requirement that it assume full responsibility for water utilities, noting that the projected annual cost is closer to $3,100 rather than the $500 initially anticipated.

After further Council discussion, Councilmember Lentz made a motion, seconded by Councilmember Davis, to waive the sewer portion of Silverspot Nursery School’s utility payment over the duration of their two-year lease (through July 31, 2027) and reimburse Silverspot Nursery School back of any sewer charges they have already paid to the City. The motion was carried unanimously by all present.

Ayes: Councilmembers Davis, Kern, Lentz, O’Connell and Mayor Mackin Noes: None

Absent: None
Abstain: None
Councilmembers also reminded staff they are looking forward to having a conversation and update from Silverspot Nursery School after the completion of the first year of the lease agreement or July 31st, 2026.

NEW BUSINESS
M. Receive Security Update on Flock Cameras
Over the past several months, there has been increased public discussion regarding the use of Automated

March 5, 2026

License Readers (ALPR) technology, particularly involving the vendor FLOCK Safety. Police Chief Macias and Police Commander Garcia provided a security update on Flock Cameras stating that the department remains committed to balancing public safety needs with privacy protection.

Police Commander Garcia also reported that ALPR cameras has proven to be a valuable investigative tool that has supported stolen vehicles recovery, notification, and crime reduction and their use must remain lawful, limited, transparent, and accountable.

After Council questions, Shelley Hodes asked a question about tracking vehicles that have no license plates.

Erin Becker commented that she liked the transparency of the ALPR Community Engagement Letter and she also recommended an external and independent audit of the ALPR program.

Councilmembers thanked the Polic Department for their update.

N. Pilot Program for Use of a Camera in the Community Park City Manager Dennis reported that the policy of the pilot program for use of a camera in the community park is before the Council.

After no council questions, Clint Cardoza asked council to support the program after he was a victim of a pitbull attack.

Linda Salmon, Michele Salmon, Steve, a resident, and Erin Becker encouraged the Council not to support the pilot program due to invasion of privacy concerns and concerns about government surveillance in a low crime safe community.

Anthony Dana shared his concerns about AI usage and who can access the data.

Linda Salmon, Fran, a resident, and Michele Salmon commented that this issue is more about enforcing rules for off-leash dogs.

Al Cardoza commented that his son was attacked by the pitbull and this is a proactive program where the City can monitor an area where police cannot be for 24 hours a day. He also asked how many off-leash dog citations had Police Chief Macias issued during her tenure? After council discussion, Councilmember Kern made a motion, seconded by Councilmember Mackin, to approve a 90-day pilot program for use of a camera in the community park. The motion was denied by a 3-2 vote.

Ayes: Councilmember Kern and Mayor Mackin
Noes: Councilmember Davis, Lentz and O’Connell

Absent: None
Abstain: None
Councilmembers took a brief recess.

February 2026 Review
The City's overall investments and cash balances decreased by net $277K from the previous month, primarily due to the residual payment of $468K towards a fire apparatus ordered in 2023, offset with an increase in sales taxes and utility billing receipts.

As reflected on Page 1, the BNY Mellon agency bonds subtotal grew to $8M. The City continues to seek and purchase longer term bonds with rates higher than LAIF to ladder maturities when available. One $1M bond earning 3.75% was redeemed and offset with purchases of two bonds, each for $1M, with rates of 4.0% and 4.05%. The City also moved $2M of noninterest earning funds from WFB to the BNY Custody Money Market account.

The shift in balances from WFB to higher-earning accounts in BNY Custody Money Market accounts resulted in a slight increase in the City's portfolio weighted interest to 3.56%, slightly higher than the 2-year Treasury rate benchmark of 3.38%.

The City's Cash with Fiscal Agents February 2026 $8.8M balance is primarily comprised of $7.3M of the PARS trust accounts and $1.5M of the 2023 Bond proceeds held in trust, as reflected on Page 1. The increase of $194K included a transfer of $74K to cover March debt service payments, and the remaining was for interest earned on the 2023 Bond series and PARS trust accounts.

City Council Staff Report
Meeting Date: April 2, 2026
From: Jeremy Dennis, City Manager
Subject: Adopt Resolution Authorizing the Director of Public Works or the City Clerk to Accept and Consent to Deeds
or Grants of Real Estate
Recommendation
Staff recommends adopting a resolution authorizing the Director of Public Works or the City Clerk to accept and consent to deeds or grants of real estate.

Background
Section 27281 of the Government Code pertains to the requirements for recording deeds or grants conveying any interest in or easement upon real estate to political corporations or governmental agencies for public purposes. Specifically, it states that such documents must not be accepted for recordation without the consent of the grantee, evidenced by a certificate or resolution of acceptance attached to the deed or grant.

In 1977, the Brisbane City Council adopted Resolution No. 1977-56 authorizing the Director of Public Works to accept and consent to deeds or grants of real estate.

Discussion
Should the Director of Public Works not be available to accept and consent to deeds or grants of real estate, this resolution will authorize the City Clerk to have acceptance authority. Having options will help expedite the recording process.

Generally, before deeds or grants of interest in real property are accepted, City Council provides its consent and authorizes the deed or grant to be recorded. From time to time, however, the City may require an easement or a small section of property for utility or similar purposes. In those cases, the Public Works Director has accepted the easement without taking the item to Council. Accordingly, similar to the Resolution in 1977, prior to the Director of Public Works or the City Clerk accepting and consenting to any deed or grant, the relevant official shall notify the City Council, in writing, the name of grantor and purpose of the deed or grant for which the official intends to accept and consent.

Fiscal Impact
None.

City Council Staff Report
Meeting Date: April 2, 2026
From: Maz Bozorginia, Public Works Director, Jerry Flanagan Subject: Adopt Resolution Approving and Recertifying of the City of Brisbane's 2026 Sewer System Management Plan
Recommendation
Adopt a resolution approving and re-certifying the City's 2026 Sewer System Management Plan (SSMP).

Background
The California State Water Resources Control Board (SWRCB) adopted the Statewide General Waste Discharge Requirements (WDRs) for Sanitary Sewer Systems (Order No. 2006-0003- DWQ) on May 2, 2006, to establish uniform, statewide regulatory requirements governing the operation, maintenance, and management of wastewater collection systems. These requirements apply to all public agencies that own or operate sanitary sewer systems consisting of more than one mile of pipeline conveying wastewater to a publicly owned treatment facility. The 2006 Order was subsequently amended in 2008 and 2013 to clarify and strengthen regulatory provisions.

On December 6, 2022, the SWRCB adopted the reissued Statewide WDR (Order No. 2022- 0103-DWQ), which became effective on June 5, 2023, thereby rescinding and replacing the 2006 Order. The reissued Order incorporates updated regulatory requirements, enhanced reporting and monitoring provisions, and expanded technical criteria, including more prescriptive requirements for the development, implementation, and periodic evaluation of Sewer System Management Plans (SSMPs).

Pursuant to the Statewide WDRs, each enrolled sanitary sewer system is required to develop, implement, and maintain an SSMP that documents the agency’s policies, procedures, and activities for the proper management, operation, and maintenance of its wastewater collection system. The SSMP must address key program elements, including system inventory, operations and maintenance, overflow emergency response, fats, oils, and grease (FOG) control, capacity management, monitoring and reporting, training, and program audits. The SSMP is required to be updated at a minimum frequency of once every six (6) years and must be recertified by the governing body upon completion of any significant revisions.

Discussion
The 2026 Sewer System Management Plan represents the City of Brisbane’s formal certification of compliance with the requirements set forth in Statewide WDR Order No. 2022-

0103-DWQ. This document establishes the City’s comprehensive framework for ensuring regulatory compliance, minimizing sanitary sewer overflows (SSOs), and maintaining the longterm reliability and resilience of the wastewater collection system. As a living document, the SSMP is subject to ongoing evaluation and refinement to incorporate regulatory updates, operational improvements, and evolving best management practices.

Adoption of this Resolution is not a project under CEQA because it is a continuing administrative activity, such as general policy and procedure making, and not applied to any specific instance. CEQA Guidelines, Section 15378 (b)(2). Accordingly, no further environmental review is necessary.

Fiscal Impact
None as a direct result of the recommended actions.

Blockage – An object that partially or fully hinders flow through a sewer pipeline. The blockage can be caused by debris in the sewer, grease buildup, root intrusion, or a partial or full collapse of the pipeline. Also known as a stoppage.

California Integrated Water Quality System (CIWQS) – A computer system used by the State and Regional Water Quality Control Boards to track information about SSOs, among other information. CIWQS is the tool used for online submittal of SSO details, which are then made available to the public. Website: http://www.swrcb.ca.gov/ciwqs/ Enrollee – The legal public entity that owns a sanitary sewer system, as defined by the Statewide WDR. Also known as a sewer system agency or wastewater collection system agency.

Geographic Information System (GIS) – A database linked with mapping that records sewer system information. The GIS database could include sewer features such as pipe location, diameter, material, condition, or last date cleaned or repaired. GIS maps also typically contain base information such as streets and parcels.

Infiltration – The seepage of groundwater into a sewer system, including from service connections. Seepage frequently occurs through defective or cracked pipes, pipe joints, connections or manhole walls and joints.

Inflow – Water discharged into a sewer system from such sources as roof leaders, cellars, yard and area drains, foundation drains, through holes in manhole covers, cross connections from the storm system or street wash waters. Inflow differs from infiltration in that it is a direct discharge into the sewer rather than a leak through defects in the sewer.

Lateral or Private Lateral – The privately-owned sewer pipeline that conveys wastewater from the premises of a user to the City’s sewer system. The upper lateral extends from the building to property line (or easement line). The lower lateral extends from the property or easement line to the connection to the City-owned sewer main pipe.

Overflow Emergency Response Plan (OERP) – This document identifies measures that are needed to respond to sanitary sewer overflows in a way that maximizes the protection of public health and the environment.

Rehabilitation and Replacement Plan (also referred to as a Capital Improvement Plan) – Identifies and prioritizes system deficiencies and implements short-term and long-term rehabilitation actions to address each deficiency.

San Francisco Bay Regional Water Quality Control Board – Also known as Region 2 or RWQCB. This regulatory agency preserves, enhances and restores the quality of California's water resources, and ensures their proper allocation and efficient use for the benefit of present and future generations. Website: http://www.waterboards.ca.gov/sanfranciscobay

City of Brisbane – Sewer System Management Plan vi
Sanitary Sewer Spill (Spill) – Any release, discharge or diversion of untreated or partially treated wastewater from a sanitary sewer system, including releases that reach waters of the United States, overflows or releases that do not reach water of the United States, and backups into buildings and/or private property caused by conditions within the publicly owned portion of the sewer system.

Sanitary Sewer System – Any system of pipes, pump stations, sewer lines, or other conveyances, upstream of a wastewater treatment plant head works used to collect and convey wastewater to the wastewater treatment plant.

Sewer Pipe Blockage Control Program –Program implemented at the discretion of the agency, based on the identified causes of sewer overflows, to reduce the discharge of fats, oils and grease into the sewer system.

Sewer System Management Plan (SSMP) – A series of written programs that address how a collection system owner/operator conducts daily business. Each SSMP is unique for an individual discharger. The plan includes provisions to provide proper and efficient management, operation, and maintenance of sanitary sewer systems, while taking into consideration risk management and cost benefit.

Spill Emergency Response Plan (SERP) – This document identifies measures that are needed to respond to sanitary sewer overflows in a way that maximizes the protection of public health and the environment.

State Water Resources Control Board – Also called the State Board. This agency developed and passed the Statewide Waste Discharge Requirements for collection systems and maintains the spill reporting web site.

System Evaluation and Capacity Assurance Plan – A required component of an agency’s SSMP that provides hydraulic capacity of key sanitary sewer system elements for dry weather peak flow conditions, as well as the appropriate design storm or wet weather event.

Statewide Waste Discharge Requirements – The Statewide General Waste Discharge Requirements for Sanitary Sewer Systems was adopted by the SWCRB in 2023 (Order No. 2022-0103-DWQ).

Wastewater Collection System – See Sanitary Sewer System.

City of Brisbane – Sewer System Management Plan 2
C. Regulatory Context
The City of Brisbane has adopted this SSMP in accordance with the Statewide General Waste Discharge Requirements General Order for Sanitary Sewers (GWDR). The first SSMP to be adopted by City Council was in August 2006 under General Order No. 2006-0003-DWQ. Since the first adoption of the SSMP, the plan has been audited and updated to remain compliant with the SWRCB’s regulations, including Order No. WQ-2008-0002-EXEC effective in February 2008 and Order No. WQ-2013-0058-EXEC effective in September 2013. The SSMP was adopted and approved previously by City Council in 2010 and most recently on October 1, 2020.

Under the reissued General Order, 2022-0103-DWQ, effective on June 5, 2023, the SSMP must be updated within every six (6) years after the required due date of its last plan update and audited internally every three (3) years. The completed SSMP updates and audits are uploaded to the California Integrated Water Quality System (CIWQS). A copy of the SSMP Revision Log can be found in Appendix A.

D. SSMP Update and Audit Schedule
The City’s SSMP update schedule is shown in Table 1-1 below and follows the required update plan for every six (6) years. The SWRCB has created an online look-up tool to show each System’s SSMP audit and update due dates.

E. City of Brisbane Service Area and Collection System
The City of Brisbane is located within the County of San Mateo, with the City of San Francisco directly to the north, and provides sanitary sewer services to the residents and businesses within its 3.4 square mile service area. The service area consists of approximately 4,900 residents, several commercial areas and some light industrial development. The wastewater collection system consists of more than 80,000 feet of laterals, mains, trunks and 20,000 feet of force mains, ranging in size from 6 to 24 inches in diameter. Additionally, there are approximately 4,350 feet of private sewers consisting of 4- and 6-inch diameter pipelines. A series of gravity

City of Brisbane – Sewer System Management Plan 3
collection system mains and smaller lift stations convey most of the wastewater flow to the Valley Drive Lift Station. The wastewater is then delivered to the 66-inch diameter City of San Francisco (SFPUC) interceptor and ultimately conveyed to the SFPUC Southeast Treatment Plant.

The City of Brisbane currently has a wholesale wastewater service agreement with the SFPUC, to convey, treat, and dispose of wastewater through the SFPUC treatment plant facilities. The City also has an agreement with the City of South San Francisco to receive and provide sanitary sewer service from a small commercial area located just outside the southern border of the City of Brisbane.

B. Legally Responsible Official
Per Section 5.1 of the Order 2022-0103-DWQ, the Legally Responsible Official (LRO) must have responsibility over the entire sanitary sewer system and have the authority to make decisions governing operations of the sewer system, including explicit or implicit duty of making capital improvement recommendations. Furthermore, the LRO must have or be in direct authority over individuals that:

1. Possess a recognized degree or certificate related to operations and maintenance of the sewer system, and/or

2. Have professional training and experience related to the management of sanitary sewer systems, demonstrated through extensive knowledge, training and experience.

In consideration of the above criteria, the City of Brisbane has designated the Director of Public Works, Maz Bozorginia, as the primary LRO for the Brisbane collection system.

C. Chain of Communication for Reporting and Responding to Spills In response to any spill event, the City of Brisbane Public Works implements a Spill Emergency Response Plan, which is discussed in detail in Element 6. The Spill Emergency Response Plan provides directions for the notification of City Staff and the California Office of Emergency Service (Cal OES).

If a spill is reported to City Hall during working hours, the Public Works Administrative Assistant will make note of the time reported, the name and contact information of the reporting party, and location and details of the spill. The Administrative Assistant will immediately notify the Public Works Supervisor or Utility Team Leader and provide the recorded information, and appropriate field crews will be dispatched to the site. Once City crews have responded to the site and assessed the situation, they will report back to the Public Works Supervisor or Utility Team Leader, who will then notify the Deputy Director, Public Works Department - Utilities with the details of the spill.

City of Brisbane – Sewer System Management Plan 9
For spills reported during non-working hours to the police or fire departments, dispatch will record the time reported, the name and contact information of the reporting party, and location and details of the spill. This information will be relayed to the Public Works Supervisor or Utility Team Leader or directly to on-call personnel if the Public Works Supervisor or Utility Team Leader cannot be reached. The Public Works Supervisor or Utility Team Leader will relay the details of the spill and dispatch the on-call personnel to the scene. The Deputy Director, Public Works Department - Utilities will be notified on the next working day unless the spill requires reporting within 2 hours, in which case, notification will occur as soon as feasible after the spill is corrected.

The City of Brisbane currently has a wholesale wastewater service agreement with the SFPUC, to convey, treat, and dispose of wastewater through the SFPUC treatment plant facilities. The City and the SFPUC meet to review the service agreement every few years, as needed.

The City also has an agreement with the City of South San Francisco to receive and provide sanitary sewer service from a small commercial area located just outside the southern border of the City of Brisbane.

City of Brisbane – Sewer System Management Plan 11
Element 4 – Operation and Maintenance Program
A. Collection System Map
The City currently has electronic maps of the entire sewer system in GIS format. As part of the 2003 Sanitary Sewer Master Plan development, all of the City's sewer manholes were surveyed and inspected, documenting size, rim and invert elevations, location coordinates, condition, and size and type of pipes entering and exiting. As such, the City now has electronic maps that show accurate manhole locations with rim and invert elevations and pipe sizes, lengths, and materials.

Maps include manhole and pipe IDs and can be cross-referenced with electronic street and parcel maps to give additional location information. Direction of flow can be determined from manhole invert elevations.

In 2016 the City updated the City’s Sanitary Sewer Maps after extensive field verification of the entire sanitary sewer system. This field information was then georeferenced in AutoCAD and mapped with a satellite imagery background into a 37-page map book of the entire system. The City has merged these CAD maps with the City’s GIS program to create searchable maps based off the CCTV database. A copy of the current sanitary sewer map system can be found in Appendix I.

In addition to the sanitary sewer maps, the City also maintains an electronic map of all applicable stormwater conveyance structures in GIS format. The City also has various historical sewer maps and construction plan sets, for both public and private sewers, all maintained in a databaseorganized filing system.

B. Resources and Budget
The City has a reliable, consistent funding source for collection system operations, maintenance, and repair through a dedicated Utility Fund. Revenues for this fund are generated by sewer service charges and connection fees, as well as some revenues that are part of the Guadalupe Valley Municipal Improvement District (GVMID) (a special district that the City Council also oversees). All sewer service charges and connections fees for the City and GVMID are the same.

The sewer operating budget includes funding for maintenance personnel salaries and benefits, insurance, services and supplies, and depreciation. Services and supplies include safety clothing, communications equipment, equipment maintenance, maintenance of structures, improvements, and/or grounds, association memberships, general office expenses, professional services, equipment rental, special department expenses, small tools and supplies, travel and training, and utility and wastewater treatment costs. The adopted budgets also include department objectives and associated performance measures.

The City has annual capital improvement budgets in addition to operations/maintenance budgets.

Capital projects vary from year to year. The Public Works Director requests funding from the City Council for capital improvement projects on a regular basis; however, the amount the Council allocates in any given year for sewer projects depends upon the City's overall capital improvement priorities for water, sewer, storm drain, streets, buildings, and grounds.

City of Brisbane – Sewer System Management Plan 12
The 2017 Sanitary Sewer Master Plan Update developed a list of priority-based Capital Improvement Projects. A couple of major developer-funded upgrades to the City’s Sanitary Sewer System were designed and implemented, which increased the capacity of flow at the Sierra Point Lift Station and increased flow in the existing gravity lines at Sierra Point. These projects helped to mitigate the hydraulic deficiencies identified in the 2017 Sanitary Sewer Master Plan Update.

C. Prioritized Preventive Maintenance
The City's Prioritized Preventive Maintenance program consists of five main components: 1) annual chemical foaming for root control, 2) annual cleaning for known sewer main segments with blockage issues, 3) investigation and resolution of customer complaints, 4) lift station maintenance, and 5) keeping maintenance activity records. Each of these components is described in more detail, as follows, along with plans for improvements:

Root Control: City staff chemically treat approximately 16 sanitary sewer main locations quarterly. As new areas of root intrusion are identified, City crews add them to the list for quarterly chemical root control. The City currently uses "Root-X" in its chemical root control program. Maintenance staff initiate CCTV inspections for line sections scheduled for chemical root control in advance to determine if root control is effective or if adjusting the frequency, additional volume of chemical used, or mechanical cleaning is needed to control root growth.

Sewer Main CCTV Inspection Program: City staff have continued an ongoing CCTV inspection program with the intention of shifting the City’s sanitary sewer system maintenance from reactive to proactive. Staff can inspect 1/3 of the gravity system with CCTV annually. In addition to identifying areas needing grit and root removal, the high frequency CCTV inspections and cleaning schedule help to identify sections of main to repair or replace. The crew has utilized CCTV to inspect over 28,000 linear feet (LF) of sewer main annually.

Sewer Cleaning: The CCTV inspection program allows the City to add additional line sections to a list of locations that need attention once a year or more, which has led to a more proactive sewer cleaning program.

As the City crews perform CCTV inspections of the City’s gravity sewer mains and manholes throughout the year, each CCTV inspection is saved as a PDF video report with condition assessment, photos and distances of issues within the pipe, and notes regarding any issues at the manhole. The pipe sections are rated at the time of inspection, and their inspection frequency is based upon this rating. These reports are then added to the maintenance program spreadsheets. A table of this CCTV Inspection Rating System is included below.

Investigation and Resolution of Complaints: When customers contact the City with complaints about sewer issues, appropriate staff personnel are promptly dispatched to the location to investigate. If the blockage is between the building and the mainline, City crews inform the property owners of their responsibility to contact a plumber to assess and fix the problem. (The property owner owns and is responsible for maintaining the sewer lateral from the property structure up to and including the connection at the City’s sewer main.) Lift Station Maintenance: The City currently owns and operates three sewer lift stations.

City crews perform regular maintenance at all stations on a prioritized schedule, as well as a fourth lift station servicing the City’s Fire Station. The City's main lift station, the Valley Drive Lift Station, has a detailed operations and maintenance manual that City crews use to schedule maintenance activities. The City also contracts for annual standby generator maintenance at each of the four lift stations.

Keeping Maintenance Records: City crews track locations and details of sewer maintenance activities using Mobile MMS, a computerized maintenance management system (CMMS).

Pertinent information is stored in the Public Works Database for future review and retrieval.

Plans for Improvement: City staff plan to make the following improvements to the Prioritized Preventive Maintenance program:

1. Schedule additional sewer main CCTV inspections and cleaning on an annual basis, to increase the overall percentage of the City's system that is regularly cleaned; and

2. Continue to develop improved electronic and paper systems for tracking sewer maintenance activities to provide enhanced analysis and reporting capabilities.

D. Scheduled Inspections and Condition Assessment
As part of the 2017 Sanitary Sewer Master Plan Update, the City identified and prioritized structural deficiencies for its collection system and implemented a Capital Improvement Program of prioritized short-term and long-term actions. The assessment of structural deficiencies was based on video surveys of approximately 42,000 linear feet of sewer line and inspections of all manholes through the City’s Sewer Main CCTV Inspection Program, and flow modeling to

City of Brisbane – Sewer System Management Plan 14
evaluate hydraulic deficiencies. Uniform condition assessment criteria were applied during review of the video inspections to determine deficiency ratings.

The City has conducted a flow monitoring study to evaluate rainfall induced infiltration and inflow (I&I) and to establish appropriate peak flow criteria for sizing wastewater facilities. The study will help to measure the degree to which I&I occurs across the City (utilizing smoke testing), calibrate the City’s sanitary sewer model, and prioritize future system assessment and rehabilitation efforts.

City crews perform station checks at each of the City's three sewer lift stations, as well as the Fire Department’s lift station, on a daily basis to ensure proper operation and identify any unusual operating characteristics. Sewer flow rates from central Brisbane (primarily residential with some commercial) are tracked with an ultrasonic transducer, and pumped flows from the Valley Drive Lift Station are tracked via magnetic flowmeters on the two discharge lines. City crews monitor these flows on a daily basis, noting and investigating any anomalous readings.

E. Contingency Equipment and Replacement Inventories
The following describes critical contingency equipment for the City's sewer system and lift stations:

Valley Drive Lift Station: This station utilizes four submersible non-clog sewage pumps, two of which are 50 horsepower and two 150 horsepower. Both sets of pumps discharge through two separate force mains, which allows for ongoing operation if one force main becomes non-operational. The two force mains also have a valved interconnection, which allows either set of pumps to discharge to either force main to allow maximum maintenance flexibility. The submersible pumps include thermal and moisture intrusion alarms to protect the pumps from mechanical failure, and various pressure and flow rate alarms will automatically shut down pumps in the event of a problem. This station has a 450-kilowatt propane-fired standby generator with an automatic transfer switch that powers the entire station in the event of a power failure. Two 500-gallon propane tanks fuel the standby generator, and City crews keep the tanks at least half-full at all times. The standby generator exercises on a weekly basis. A primary ultrasonic transducer, with a secondary backup, controls pump operation at this station. There are also backup mechanical floats to activate alarms in the event both transducers fail. The original channel grinder was replaced with a Franklin Miller Dimminutor channel grinder, which is capable of processing 13.8 million gallons a day of wastewater.

Sierra Point Lift Station (Lift Station #4): This station utilizes three submersible non-clog sewage pumps, all of which are 23 horsepower. The wet well also contains two Franklin Miller Dimminutor channel grinders. This station has a 60-kW standby diesel-powered generator with a 380-gallon fuel tank to keep the station operational in the event of a power failure, which is exercised on a weekly basis. A pressure level transmitter controls pump operation and there are backup floats switches if the transmitter fails. In 2020, the entire lift station was upgraded to meet the demands of the new commercial developments at Sierra Point, which included upgrades such as a new wet well, piping, instrumentation, and a landfill gas detection and monitoring system.

City of Brisbane – Sewer System Management Plan 15
Harbormaster Lift Station (Lift Station #1): This station utilizes two submersible selfcleaning semi-open channel impeller pumps. This station has an 80-kW standby dieselpowered generator with a 300-gallon fuel tank that will operate the entire station in the event of a power failure. The station exercises the generator on a monthly basis. The pumps, wet well piping, isolation valves, and the submerged flex hoses for this station were replaced over time. The station has a pressure transducer for pump operation and backup mechanical floats for alarms and pump control.

Fire Station No. 81 Lift Station (Lift Station #5): The City of Brisbane’s Fire Station No. 81, located at 3445 Bayshore Boulevard, is managed by North County Fire Authority (NCFA).

This fire station contains a wet well with two pumps operated by pressure transducers with backup mechanical floats for alarms and pump control. The City of Brisbane Public Works Department performs routine inspections and cleaning of this station and equipment, but repairs and equipment upgrades are the responsibility of NCFA.

Contingency Equipment: City crews maintain multiple portable sump pumps and generators for use during a sewer emergency. The City has a 2,500-gallon Vactor truck that is utilized for capturing and containing any sewer overflow volume, as well as cleanup and line clearing activities with a new truck. This truck has a small wheelbase and a tighter turning radius to help navigate the City’s narrow and twisty streets. City crews maintain an inventory of extra pipes of varying diameters and materials as well as necessary couplings and fittings to allow prompt repair of most gravity sewer failures. An equipment inventory list can be found in Appendix J.

F. Training
City staff participate in regular ongoing training activities, both in-house and through outside vendors. In-house safety training occurs on a bi-weekly basis, with some of the training seminars specific to collection systems management. The Public Works Supervisor possesses a Collection System Maintenance (CSM) Grade 2 certificate as issued by CWEA. Other Public Works employees have CSM Grade 1 and 2 certificates as well. CWEA certification requires biannual submittal of 12 contact hours of training related to Collection Systems Maintenance.

Crew members attend seminars by CWEA and other outside entities to accumulate contact hours.

City staff also participate in on-the-job training, where crew members are cross trained on different aspects of municipal maintenance. This helps ensure all crew members are able to respond to a variety of emergency situations. Certain crew members are also required to maintain Class B driver's licenses with air and tanker endorsements in order to operate the Vactor truck. A list of staff training can be found in Appendix J.

G. Outreach to Plumbers and Building Contractors
The City of Brisbane, as a member of the Bay Area Clean Water Agencies (BACWA), has access to plumber outreach materials if necessary and will evaluate sending materials to local plumbers. The City also maintains a list of qualified contractors for public projects, which is updated annually.

City of Brisbane – Sewer System Management Plan 16
Element 5 – Design and Performance Provisions
A. Standards for Installation, Rehabilitation, and Repair The City has identified minimum design and construction standards and specifications for installation of new sewer systems. The City's design standards are included as Appendix D in this document. The City also has construction specifications for installation of new sewers via pipe bursting or reaming from two completed sewer rehabilitation capital improvement projects.

B. Standards for Inspection and Testing of New and Rehabilitated Facilities The City has identified minimum design and construction standards and specifications for rehabilitation and repair of existing systems. The City's standards are included as Appendix D in this document. Inspection of new and rehabilitated facilities is performed by the Public Works Inspector in the field during and at the completion of construction. Depending on the situation, inspections vary from visual inspections to air/water pressure testing, mandrel testing, or video inspection. For City capital improvement projects, testing requirements are called out in the construction specifications, and typically include air testing, mandrel testing, and video inspection for sewer mains and water leakage testing for manholes.

Design standards and specifications will be periodically reviewed by City staff to ensure the industry’s current best practices are considered, and to confirm if any updates are necessary.

City of Brisbane – Sewer System Management Plan 17
Element 6 – Spill Emergency Response Plan
A. Staff Notification
Sanitary sewage spills (i.e., discharges of sewage from any portion of a sanitary sewer system due to a sanitary sewer system spill, operational failure, and/or infrastructure failure) are typically reported in one of two ways in the City of Brisbane:

1. Observed and reported directly to City staff by a member of the public, another agency, or City crews during working hours

2. Observed and reported by a member of the public or another agency to the police department during non-working hours
During Regular Hours:

1. The Public Works Administrative Assistant will make note of the time reported, the name and contact information of the reporting party, and location and details of the spill.

2. The Administrative Assistant will immediately notify the Public Works Supervisor or Utility Team Leader and provide the recorded information.

3. The Public Works Supervisor or Utility Team Leader will then dispatch appropriate field crews to the site.

4. Once City crews have responded to the site and assessed the situation, they will report back to the Public Works Supervisor or Utility Team Leader, who will then notify the Deputy Director, Public Works Department - Utilities with the details of the spill.

During Non-Working Hours:

1. Spills reported to the police or fire departments, dispatch will record the time reported, the name and contact information of the reporting party, and location and details of the spill.

2. The information will be relayed to the Public Works Supervisor or Utility Team Leader or directly to the on-call personnel if the Public Works Supervisor or Utility Team Leader cannot be reached.

3. The Public Works Supervisor or Utility Team Leader will relay the details of the spill and dispatch the on-call personnel to the scene.

4. The Deputy Director, Public Works Department - Utilities will be notified on the next working day unless the spill requires reporting within 2 hours, in which case, notification will occur as soon as feasible after the spill is corrected.

To minimize spill impacts, the main priorities shall be protection of public health and the environment. For all spills, if there is potential for public contact with sanitary waste, the affected area shall be cordoned off to prevent public access, using traffic barricades, warning

City of Brisbane – Sewer System Management Plan 18
tape, cones, signs, etc. All spill volume that is recoverable shall be contained and pumped back into the sanitary sewer system, either with trash pumps or a Vactor truck. If the spill reaches the storm drain system, a downstream catch basin or storm system manhole shall be plugged with sandbags or inflatable drain plugs, and the contained volume pumped out or vacuumed with the Vactor truck. Impacted areas on the surface shall be washed down, with all wash water contained and returned to the sanitary sewer system. Impacted areas, including the storm drain system, shall be cleaned and disinfected, as appropriate, to eliminate any public health threats.

Should any spill volume visibly impact surface waters, the Water Quality Technician will pursue follow-up sampling and City staff will pursue mitigation efforts in coordination with appropriate regulatory agencies.

A copy of the full Brisbane Spill Emergency Response Plan and Spill Documentation Packet can be found in Appendix G.

In 2015 City Staff developed and implemented a set of Lift Station Emergency Response Plans, to be stationed at all the City maintained Lift Stations. These plans include maps, retention times, emergency contacts, and site-specific response plans. The purpose of these Emergency Response Plans is to mitigate any impact on the local waterways from a failure at any of the City’s Lift Stations. These Lift Station Emergency Response Plans can be seen in Appendix H.

City staff conduct “mock” field exercises that incorporate all steps of the SERP procedure. The Public Works Supervisor determines the type of field exercise that will be conducted by City staff.

City of Brisbane – Sewer System Management Plan 31
Element 7 – Sewer Pipe Blockage Control Program
The City currently implements a Sewer Pipe Blockage Control Program to reduce any potential blockages caused traditionally by fats, oils, grease (FOG), with the addition of debris and rags.

Although FOG has not been found to be a significant contributor to SSOs in the City of Brisbane, the City will implement the Sewer Pipe Blockage Control Program as follows:

A. Source Identification:

The source of the highest-concentration of FOG discharge to the sewer system are likely from the City’s food service facilities. There are typically between 30 and 40 food service facilities in Brisbane at any one time. These facilities are primarily located in “the Village” area of Brisbane along Old County Road and in the commercial district on Visitacion Avenue. Additional facilities are scattered in Crocker Industrial Park and at Sierra Point in association with the hotels and office buildings.

Other potential FOG sources may also be from residences in central Brisbane or the Northeast Ridge neighborhoods.

B. Source Control:

Source control measures for food service facilities are primarily accomplished through San Mateo County’s Environmental Health Department inspection program. County health inspectors enforce operation and maintenance of grease traps and ensure proper management of food service waste. In addition, if an SSO occurs in a residential or commercial area due to FOG buildup, City staff will distribute door hangers alerting residents that grease was found in sewer lines in their area and directing them to properly manage their FOG.

The installation of grease removal units is required in all new restaurants and in tenant improvements of existing restaurants. Installation of a grease removal unit is also required in all new commercial and industrial food-handling facilities and in tenant improvements of existing commercial and industrial food-handling facilities.

C. Inspection and Maintenance:

The City relies on the County Health inspectors for food service facility inspections. The County inspectors are required to inspect all food service facilities on a regular basis (at least annually) and can provide enforcement on issues related to FOG management and disposal. County inspectors will notify City staff if there is a problem at a particular facility requiring additional action.

City staff have identified various locations throughout the City that may be potential “hot spots” for FOG and have implemented cleaning schedules to mitigate and prevent any potential sewer pipe blockages.

City of Brisbane – Sewer System Management Plan 32
D. Legal Authority:

The City has adequate legal authority to prohibit discharges of FOG to the collection system as detailed in the Brisbane Municipal Code. Relevant sections of the Code are included in Appendix E.

In addition, the City’s municipal code adopts San Mateo County’s environmental health code as the applicable regulations for food service facilities.

City of Brisbane – Sewer System Management Plan 33
Element 8 – System Evaluation, Capacity Assurance and Capital Improvements
A. System Evaluation and Condition Assessment
The City's Sanitary Sewer System Master Plan, which was developed in 2003 and updated in 2017, evaluated the existing sewer system assets, updated the City’s sewer system hydraulic model, and provided recommended rehabilitation projects based on the findings. Utilizing a regular CCTV inspection program, the City has been able to identify and prioritize several sewer system replacements and repairs over the years, which has helped to develop future capital improvement projects based on condition assessment recommendations.

The City has also conducted a wastewater flow monitoring study to measure the degree and general location that rain induced infiltration and inflow (I&I) enters the City’s sanitary system.

This I&I study helps to establish baseline sanitary sewer flows, identifies the peak flows during rainfall events and the impact it has on sewer capacity, and prioritizes specific sections of the sewer system that need further condition assessment, with follow up methods such as smoke testing. This work helps to identify and address weaknesses in both the public and private sewer systems.

B. Capacity Assessment and Capital Improvement Plan
The City's Sanitary Sewer System Master Plan provided a capacity evaluation of the sewer system. These evaluations were based on hydraulic modeling of the sewer system using SewerCAD software. Modeling was done based on escalating peaking factors applied to base flow estimates for future (build-out) flow conditions. Flow estimates were prepared using peaking factors of 3, 5, 7, and 9. City staff decided to use a peaking factor of 5 to simulate design wet weather events, and used the following flow depth criteria for determining which gravity sewers were hydraulically deficient:
 When the peak flow depth exceeds one-half full for pipelines 10-inches in diameter or less
 When the peak flow depth exceeds two-thirds full for pipelines 12-inches in diameter or greater
A summary of the City’s gravity sewer assets from the Sanitary Sewer Master Plan can be found in Appendix K.

The City’s Sanitary Sewer Master Plan also presented recommended capital improvement programs for mitigating both hydraulic and structural deficiencies in the City's sewer collection system. The City has corrected the hydraulic deficiencies identified in both the 2003 and 2017 Master Plans by upsizing existing six-inch diameter vitrified clay pipes to eight-inch diameter high density polyethylene pipe through trenchless rehabilitation processes (pipe bursting). The hydraulic deficiencies for the Sierra Point Lift Station, identified in the Master Plan, have been remedied and have allowed increased capacity in handling all future flows for the Sierra Point area. A copy of the City’s most recent Sanitary Sewer System Master Plan can be made available upon request

City of Brisbane – Sewer System Management Plan 34
Element 9 – Monitoring, Measurement, and Program Modifications The City will monitor implementation of SSMP elements and measure effectiveness of SSMP elements in reducing SSOs through annual review meetings with collection system staff. During these review meetings, the following performance indicators will be evaluated:
 Number of SSOs in wet weather and dry weather
 Total number of SSOs
 Number of SSOs in each category
 Total volume of SSOs
 Total volume recovered
 Net volume of SSOs (total minus recovered)
 Total annual volume conveyed to wastewater treatment plant  Net volume of SSOs compared to total annual volume conveyed (% conveyed)  Number of SSOs caused by:
o Roots
o Grease/FOG
o Debris
o Pipe failure
o Pump station failure
o Capacity-limited pipe segment (no debris)
o Other
 Number of locations with more than one SSO in the past year  Average response time during business hours/outside of business hours  Planned/unplanned cleaning/chemical root control (LF)  Ratio of planned to unplanned cleaning/chemical root control (LF)  Number of blockages in the past year
 Number of blockages due to:
o Roots
o Grease/FOG
o Debris
o Other

City of Brisbane – Sewer System Management Plan 35
 Number of customer complaints in the last year
 Number of positive customer responses
At the annual review meetings, collection system staff will also go through the SSMP to ensure the information is current, including any updates to infrastructure, wastewater flow characteristics, new or modified operations and maintenance protocols, revised emergency response procedures, or changed organizational structure.

The main person on staff who is responsible for monitoring the effectiveness of the SSMP is the Deputy Director of Public Works - Utilities. This person will organize and oversee the annual review meetings with collection systems maintenance staff. After the annual review meeting, the Public Works Supervisor/Utility Team Leader will draft an annual review summary for the Deputy Director of Public Works - Utilities. Any SSMP modifications determined necessary during the annual review meeting will be detailed in the summary document. Minor SSMP modifications will be implemented by the Public Works Supervisor/Utility Team Leader.

Significant SSMP modifications will be reviewed and approved by the Public Works Director.

City of Brisbane – Sewer System Management Plan 36
Element 10 – Internal Audits
The City is required to conduct an internal audit of the SSMP on a triannual basis. The audit reviews the effectiveness of the SSMP and identifies if there are any deficiencies in the SSMP or maintenance processes that will need to be corrected. If updates or changes are required, the content and timeline to complete those changes are described in the audit form. The audit is conducted by City’s Public Works staff, including the engineering staff and field maintenance staff.

The most recent SSMP audit was completed and certified in October 2025, and a copy of the audit report can be found in Appendix L.

Following the audit, a comprehensive update of the SSMP will occur every 6 years in accordance with the Statewide WDR. All changes made to the SSMP are documented in the Change Log located in Appendix A.

City of Brisbane – Sewer System Management Plan 37
Element 11 – Communication Program
Public Education
The City has a link to the current SSMP on the main Sewer page of the City’s website. There is also a link to the Public Works Department with a note encouraging people to contact the City with any questions or concerns. Following is the link to that webpage. https://www.brisbaneca.gov/488/Sewer-Information
The City utilizes various media sources (utility bill inserts, weekly “Blast” updates, monthly STAR newsletters, social media) to inform utility customers of various topics including sanitary sewer collection system issues. City staff can also develop new web pages to cover specific topics such as Inflow & Infiltration (I/I) or FOG control.

Public Outreach Events
 Day in the Park – This is an annual Event held in the City of Brisbane’s Community Park. The City of Brisbane’s Public Works Department has a booth where the Sanitary Sewer Field Crew has the ability to set up a demonstration that includes a mockup sewer lateral and information points. The booth is staffed by the Maintenance Utility Workers from 8:00am – 3:00pm. This provides the public a full day to question, provide feedback, and learn about the City’s Sanitary Sewer System.  City Hall Office Hours – The City of Brisbane’s City Hall public walk-in hours are 8:30 AM – 4:30 PM, Monday through Thursday, and 8:30 AM – 12:30 PM on Fridays. City Hall Office Hours are subject to change.

Crew Interactions with the Public
The City’s Utility Maintenance workers regularly interact with the public during their daily activities. The crew is trained to handle all of these interactions with dignity and professionalism. If any of the public has questions or concerns that the crew members can’t answer, they are instructed to give out the business card for the City’s Public Works Department.

In the event of a spill that results in the closure of public areas, the City provides appropriate public notification signs and barricades to keep vehicle and pedestrian traffic away from contact with spilled sewage during spill response and cleanup.

The director may at his or her discretion provide emergency maintenance assistance to a property owner to determine if a sewer stoppage is within the public sewer or within the property owner's sewer lateral, provided that a sewer cleanout has been provided as required in Section 13.04.420(G). The city shall not be liable for the repair or replacement of any portion of the sewer lateral as a result of emergency maintenance. (Ord. No. 591, § 1, 3-19-15)

13.04.420 - Sewer installation specifications and requirements.

Sewers to be installed in the city shall satisfy the following requirements:

A. All sewers constructed in the public right-of-way shall be constructed in accordance with plans and specifications approved by the city council upon recommendation of the director. Sewer laterals shall be constructed in accordance with standard plans prepared by the director and approved by the city council.

B. Minimum size of all sewer laterals shall be four (4) inches and shall require a cleanout at the property line.

C. The minimum size of public sewers shall be eight (8) inches and standard manholes shall be placed at frequencies no greater than three hundred (300) feet or in places of change of direction or grade, except sewers twelve (12) inches in diameter or greater, under which circumstances the specific design shall be approved by the director.

D. When sewers cannot be placed in the public right-of-way or in existing rights-ofway of ten (10) feet in width or greater, special easements shall be acquired a

City of Brisbane – Sewer System Management Plan 45
minimum of ten (10) feet in width and wherever possible shall straddle existing property lines.

E. Wherever easements ten (10) feet in width or greater can be acquired, public sewers shall be extended in accordance with approved plans and specifications and in accordance with proper master planning for the area being served.

F. Wherever a public sewer can be extended along public rights-of-way or standard easements, each service shall be extended to the public sewer by a sewer lateral serving only one unit of ownership unless the city council, by resolution, approves the service of more than one unit of ownership by a lateral.

G. A cleanout shall be placed on each sewer lateral at the transition between the upper and lower portions of the lateral. The director may additionally require the installation of a backflow prevention device on the sewer lateral when he or she reasonably believes backflow has or may occur.

H. Wherever a substandard extension of the public sewer exists, i.e., a line smaller than eight (8) inch or across private easements, no further extension of the sewer line can be made until such a time as an agreement for maintenance and rights of easement for all individuals using the line is recorded with the office of the county recorder.

APPENDIX D
City Standards for
Sewer Installation, Rehabilitation, and Repair
and
Inspection and Testing of New and
Rehabilitated Sewer Facilities

DEFINITIONS
Sewage or Wastewater: This is the “used” water that contains human wastes from toilets and water from other sources such as sinks, showers, washing machines, dishwashers, etc. Industrial and commercial wastes are also considered sewage or wastewater.

Sanitary Sewer System, or Wastewater Collection System, or Sewers: These are pipes through which sewage is carried from homes and businesses to a treatment plant. The sanitary sewer system includes the main sewer lines in the streets and the branch lines to individual sewer customers called “sewer laterals.”
Sewer systems are generally designed to flow by gravity through sloped pipes until it reaches either the treatment plant or a sewage pumping station (which pumps the sewage up to another higher sewer or a treatment plant).

The term “sanitary sewer” is used because sewer pipes are separate from the pipes used for storm water drainage. This helps protect public health and the environment. In some older cities, such as San Francisco, sewage and rainwater flow through the same pipes. This can cause major environmental and public health problems because untreated or partially treated-sewage may be discharged into streams, rivers, and other water bodies during heavy rain.

Sewer Lateral: This is the sewer pipe that connects a building's plumbing system to the main sewer line in the street. Maintenance and ownership of sewer lateral pipes is the responsibility of the property owner.

Sewer Main: This is the sewer pipe that collects flow from laterals. Mains are typically larger pipes than laterals, and get larger and larger further downstream as more and more flow enters the main. Sewer mains are typically located under public streets and maintained by the City.

Sewer Cleanout: This is a pipe rising from the sewer lateral to the ground surface with a removable cap or plug. It is used to access the sewer lateral to free blockages. A sewer cleanout is usually located just inside the property line. There may be additional sewer cleanouts at various other locations on a property.

Backflow Prevention Device: This is a device that prevents sewage from backing up from a main line into a lateral beyond where it is installed. This forces an overflow outside of a home, through a manhole or cleanout, rather than inside where significant property damage may occur.

City of Brisbane – Sewer System Management Plan 57
Infiltration: This refers to groundwater (water found below the ground surface) that enters sewer pipes through cracks, pipe joints, and other system leaks. Because sewers in coastal areas are typically buried deep, they are often located below the water table. Since most sewer lines do not flow full (under pressure), groundwater “infiltrating” into the sewer line is actually more of a problem than sewage leaking out of the line. Storm events can raise groundwater levels and increase infiltration of groundwater into sewer pipes. The highest infiltration flows are observed during or right after heavy rain. Too much infiltration may overload the sewers and cause spills.

Inflow: This is rainwater that enters the sewer system from sources such as yard and patio drains, roof gutter downspouts, uncapped cleanouts, pond or pool overflow drains, footing drains, crossconnections with storm drains, and even holes in manhole covers. Inflow is greatest during heavy rainfall and like infiltration, can cause excessive flows and sewage spills.

Manholes: Sewer manholes are underground structures used to provide access to underground sewer lines and are usually found in a street, parking area or sidewalk. Access is required to periodically inspect and clean the lines. Sewer manholes typically have heavy round covers with the words “Sanitary Sewer” on the cover.

Sanitary Sewer Overflow: Sewage spills are technically called “sanitary sewer overflows” since it involves the overflow of sewage from the sanitary sewer system. Sewage overflows often occur from sewer manholes in the streets. Sewage can also backup into homes through toilets, showers, and floor drains. Sewage spills are caused by sewage filling the sewer pipes behind the clog to the point where it spills out of an opening in the system (generally the lowest manhole, shower drain or other plumbing fixture).

Average Flows: Average flows are typically dry weather sewer flows over a specific time period and often expressed in gallons per day. Average flows do not account for inflow and infiltration and are therefore not usually the basis for designing a sewer piping system.

Peak Flows: Peak flows are typically average flows multiplied by a peaking factor to account for inflow and infiltration and diurnal fluctuations. Sewer designs are usually based on peak flows, and a typical peaking factor is between three and five.

Design Flows: Design flows are the flows used to design a sewer system. Typically, they are peak flows. For the City of Brisbane’s sewer design criteria, design flows are peak flows at build-out conditions, which are average flows multiplied by a peaking factor of three.

SEWER MAINS
Materials

1. New gravity mains shall be polyvinyl chloride (PVC) or high density polyethylene (HDPE) with a maximum standard dimensional ratio (SDR) of 35 for conditions with at least three feet of cover. In cases where the City authorizes less than three feet of cover, alternate SDRs may be required. The City may require alternate pipe materials in cases with less than minimum cover or when other utilities are in close proximity to the sewer main.

City of Brisbane – Sewer System Management Plan 58

2. For sewer main replacements that are five feet or less in length, pipe materials may match existing materials (e.g., when replacing a five-foot section of vitrified clay pipe (VCP), the replacement section can also be VCP). All sewer main replacements of more than five feet shall be PVC pipe.

Sizing

1. Flow Sizing
A. Gravity mains shall be a minimum of eight inches (8”) in diameter.

B. Mains shall be designed to carry peak flows at build-out conditions (“design flows”).

Average daily flow values shall be computed based on the following table, and multiplied by a peaking factor of five (5) to determine design flows. Calculations for design flow rates shall be submitted to the City Engineer for review.

B. Sewer trenches shall not extend under the edge of gutters.

C. When necessary to locate sewers in public easements, such easement shall have a width equal to twice the depth of the sewer main, or 15 feet, whichever is greater. Sewers 24 inches in diameter or larger, or over 12 feet in depth, may require wider easements. All easements shall allow for year-round vehicular access to all manholes and cleanouts.

Clearances to other utilities/structures

1. Sewer mains shall be installed a minimum of 10 feet horizontally from all structures and existing or proposed water mains. In situations where it is not feasible to maintain a 10-foot separation, the distance may be reduced at the City’s discretion.

Therefore, in general, the minimum depth for sewer to serve a given residential property shall be three feet plus 2% times the length of the house lateral (the distance from the sewer to the center of the house). Less than minimum cover is at the City’s discretion and may require alternative pipe material.

2. Slope
Laterals shall have a minimum two percent (2%) slope. Lesser slopes are at the City’s discretion.

3. Cover/trench requirements
Sewer lateral trenches shall be backfilled with four inches of compacted fill sand prior to laying pipe. Once pipe is installed, it shall be backfilled to twelve inches above the crown with compacted fill sand, followed by native material (with rocks over two inches removed) compacted to 90% relative compaction. Native material shall extend to finished grade in unimproved areas. In existing or new streets, native material shall be followed by asphalt concrete/aggregate base lifts in accordance with the City’s Street Standards.

Clearances to other utilities/structures
Laterals shall be installed with a ten-foot minimum horizontal separation to water service lines.

Cleanouts
Each lateral shall have an approved cleanout. Cleanouts shall be located approximately six inches (6”) from the property line on private property (at the right-of-way or easement line).

2. Lateral connections to existing mains may be made by tapping the existing main only when the lateral diameter is less than or equal to three-fourths (0.75) the main line size. If this ratio is exceeded, the connection shall be made by removing a section of the main line and installing a properly sized wye fitting. Laterals eight inches in diameter and larger shall connect to the mainline at a manhole.

3. Laterals shall be constructed perpendicular to the main line and shall intersect the property line a minimum of five feet from the property corners. Exceptions will be made in the case of cul-de-sacs where perpendicular service lines are not practical.

PRESSURE SYSTEMS
Materials
All pressure systems shall utilize heat-fused high-density polyethylene (HDPE) pipe meeting Specification Section 15066, or PVC pipe meeting American Water Works Association (AWWA)’s C900 specifications with appropriate couplings.

APPENDIX F

WATER QUALITY MONITORING PLAN
Introduction
This Water Quality Monitoring Plan describes the sampling and analytical methodology along with data management protocol that will be used by the Water Quality Technician to gather water quality data in the event of sanitary sewer spill of greater than 50,000 gallons, and the time frame for the events. The water quality sampling results will enable authorities to prioritize areas of concern with regard to water quality impacts.

Contact: Caleb Cayago at 415-508-2138 (office) and 415-218-3584 (cell) Surface Water Sampling Procedures
Surface water samples will be collected using the direct grab sampling technique. New, sterile, nitrile powder-free surgical gloves will be worn by sampling personnel at all times during sampling. Sampling gloves will be changed between sampling locations.

Samples will be collected in the following order using the procedures recommended by US EPA for surface water sampling.

Order of sampling:

1. Ammonia

2. Fecal coliform

3. E. coli
Equipment and supplies

1. Cooler with blue ice

2. Sterile bacterial sampling bottles with or without preservative 3 per location (one may serve as duplicate for QC purpose

3. Gloves

4. Marking pen (water resistant of permanent sharpies)

5. Clean bucket/bailer in case need

6. Paper towels

7. Decontamination solution and a disposal bucket for storing liquid waste

8. Field log forms

9. Chain of custody and labels

10. Contact information for the Field supervisor

City of Brisbane – Sewer System Management Plan 71
Procedure:

Collect one water sample, each day of the duration of the spill at each location listed under steps 5 and 6 below using the following procedures:

1. Determine the point that the spill is discharged into waterway.

2. If the spill is occurring, the “point of discharge” location is the point where the spill is entering the waterway.

3. If sampling is performed after the spill has stopped, calculate the approximate downstream distance from the original spill location by dividing the time since the spill occurred by the estimated velocity. The velocity may be estimated by observing or dropping floatable debris in the surface water and timing how long it takes to travel over a measured distance.

4. Put on safety gloves and safety glasses.

5. Flow in Drainage Conveyance System (DCS) Prior to Discharge Sampling a. If sewage discharges to a surface water via a drainage conveyance system, collect the water sample from the manhole or other accessible structure located closest to the discharge point before the drainage conveyance system low discharges to a receiving water. Label the sample bottle “DCS-001” with the date and time. i. Take a photo of the sample location, including a reference point in the photo. ii. Fill the three labeled bottles against the direction of the water flow. Avoid sampling debris or scum layer from the surface.

6. Receiving Surface Water (RSW) Sampling
b. Upstream of Point of Discharge Sample Collection: Collect the upstream samples first from a point in the receiving water of the point of sewage discharge to capture ambient conditions absent of sewage discharge impacts. Move approximately one hundred feet (100ft) upstream of the discharge location. Label the sample bottle “RSW-001U” with the date and time.
i. Take a photo of the sample location, including a reference point in the photo. ii. Fill the three labeled bottles against the direction of the water flow. Collect samples well away from the bank, preferably at a point where water is visibly flowing. Avoid sampling debris or scum layer from the surface.
c. Point of Discharge Sample Collection: Collect the “point of discharge” samples next.

Move approximately ten feet (10ft) downstream of the point in the receiving water where sewage initially enters the receiving water. Label the sample bottle “RSW-001” with the date and time.
i. Take a photo of the sample location.
ii. Fill the labeled bottles against the direction of the water flow. Collect samples well away from the bank, preferably at a point where water is visibly flowing. Avoid sampling debris or scum layer from the surface.
d. Downstream Sample Collection: Lastly, collect the downstream of point of discharge sample. Move one hundred feet (100ft) downstream of the source location. Label the sample bottle “RSW-001D” with the date and time.

City of Brisbane – Sewer System Management Plan 72
i. Take a photo of the sample location.
ii. Fill the labeled bottles against the direction of the water flow. Collect samples well away from the bank, preferably at a point where water is visibly flowing. Avoid sampling debris or scum layer from the surface.

7. Submerge collection container into the water to the depth of 6 to 10 inches carefully to avoid:
a) contamination from land and surface debris; and b) losing the preservative tablet (sodium thiosulfate) in the bottle.

8. For safety reasons, it may not be possible to collect a bacteria sample directly into the sterile container. A clean bucket may be used to collect the sample then the sample transferred to the sterile container.

9. Alternatively, a clean sanitized bailer may be lowered into the receiving water to collect and transfer water into sterile containers sterile to minimize any possibility of contamination of the sample.

10. Fill bacterial container to the 125 ml mark, make sure there are enough containers/location to accommodate the testing needs.

11. Screw the caps on each bottle securely to avoid leakage. Avoid touching the inside of the sample bottle(s) or the cap(s).

12. Repeat the sampling process with the remaining containers.

13. Log all samples onto a Chain of Custody Document and place all samples in cooler with Blue ice. If exterior of the bottles get contaminated with highly turbid water, rinse the exterior of the bottles with deionized water before placing into the cooler.

14. If the receiving water has no flow during the duration of the spill, report “No Sampling Due to No Flow” for its receiving water sampling locations.

Fecal coliform and E. coli samples must be delivered to the laboratory within approximately five hours of sample collection to meet the six-hour holding time for these analyses.

Laboratory Quality Control Policy
 Maintain an updated ELAP certification
 Participate in third party proficiency testing
 Ensure sample is analyzed within its hold time of 6 hrs  Analyze Ten percent of the samples collected in duplicate to establish levels of precision.  Determine the acceptance and rejection of data based on established Control limits Field sampling Quality Control Policy
 Ten percent of the samples collected will be used for quality control purposes.  Duplicate samples will be used to determine laboratory method precision.  Replicate samples will be used to determine representativeness of sampling.  Field samples may be split for inter-laboratory comparisons.

City of Brisbane – Sewer System Management Plan 73
 All field instruments used in the measurement of physical, chemical, or biological parameters shall be properly calibrated and maintained. Records will be kept of these operations for each instrument.
 Decontamination of clean buckets and or bailer if used prior to sampling at a different location
 All liquid waste generated from decontamination must be collected and disposed of by the City

City of Brisbane – Sewer System Management Plan 93
MEASURED VOLUME METHOD (See page 6 of the Sewer Spill Estimation Guide) If not raining, the shape, dimensions, and depth of the spill may be used to estimate the volume.

Sketch spill with dimensions and depth (in feet)
Measure depth in several locations

1. Multiply (area) x (depth) to get volume: cu ft. Rectangle Area

2. Repeat as needed: cu ft. (length) x (width)

2. Repeat as needed: cu ft. Circle Area

2. Repeat as needed: cu ft. (dia) x (dia) x 0.785

3. Add volume from all shapes drawn to get Total
Volume: cu ft. Triangle Area
(base) x (height) x

0.5 4. Multiply (Total volume) x (7.48) to convert to
gallons: gallons
For spill of this shape draw 3 triangles, one circle, and one rectangle.

Measure depth for each shape in multiple locations and figure average.

EXAMPLE

City of Brisbane – Sewer System Management Plan 94
GUTTER FLOW ESTIMATION METHOD (See page 21 of the Sewer Spill Estimation Guide)

1. Drop a small floating object into the sewage flow and measure how far it floats in one second.

VELOCIT
Y (ft/sec)

2. Calculate the Area of flow in the gutter line in square inches.

Area of a triangle is 1/2 x Base x Height (common flow shape in gutter) AREA (in2)

3. Multiply: (in2) x .007 to get square feet (ft2) = AREA (ft2)

4. Multiply: (ft/sec) x (ft2) x 7.48 (gal/min) x 60
(sec/min) =
FLOW (gal/min)

5. Determine total spill time in minutes* TIME (min)

6. Multiply: (gal/min) x (min) = TOTAL SPILL VOLUME (gallons) * Add 30 minutes to the start time if start of spill is not witnessed or documented with photos Gutter Flow Estimation Example
For this example, let’s assume that a piece of bark floated 2ft in one second, when dropped into the sewage flow. Let’s assume that the spill lasted 16 minutes, but nobody witnessed the start, so we must add 30 minutes to bring our time to 46 minutes. 1 sq inch = .007 sq ft The area of a triangle is (1/2)Base x Height

1. That would mean that Velocity = 3ft/sec. Time = 46 minutes

2. The area of this flow would be (1/2) x 2” x 16” = 16 sq inches.

3. Convert 16 sq inches to sq ft. 16 x .007 = .112 The Area = .112 ft2

4. Flow = 2(ft/sec) x .112(ft2) x 7.48(gal/min) x 60 (sec/min)

5. Flow = 101(gal/min) x 46 minutes = 4,646 gallon Total Spill Volume EYEBALL ESTIMATION METHOD (See page 5 of the Sewer Spill Estimation Guide) Imagine amount of water that would spill from a bucket or barrel. This method useful up to 100 gallons.

This method should be used as a last resort if the other estimation methods aren’t available.

Size of bucket(s) or barrel(s) How
many? Mutliplier Estimated Volume
1 gallon water jug x1 gallons
5 gallon bucket x5 gallons
32 gallon trash can x32 gallons
