Task 3 – Flow Monitoring
T
ask 3.1 – Develop Flow Monitoring Plan
• Woodard & Curran will develop a flow monitoring plan for the sewer system. The monitoring plan will be designed to isolate major sewer basins and subbasins in the system and confirm flows in major trunk sewers. The plan will describe the strategy for the flow monitoring program and identify recommended sites for meter and, if needed, rain gauge placement. The plan will consider the location of previous meters under the 2017/18 monitoring program and existing permanent meters, as well as other critical sites (e.g., flow diversion locations, areas with anticipated significant future development). In preparing the plan, Woodard & Curran will solicit City staff input into the proposed meter locations. The plan will include maps showing the meter sites (and alternate sites should any of the primary sites be found to be unsuitable based on the site investigations under Subtask 3.2) and tributary areas, as well as a system schematic showing the location of the meters with respect to each other. The draft plan will be submitted to the City for review and approval. A workshop will be scheduled following the submittal of the draft flow monitoring plan to discuss the proposed sites and get approval from the City for moving forward with the site investigations.
Assumptions for Task 3.1:
• It is assumed that the flow monitoring program will be similar in size and scope to previous City-wide programs conducted in 2010 and 2018 (35 to 40 sites); however, the advisability of conducting a more targeted program with fewer sites focused on major trunks plus areas where the City has implemented system improvements and rehabilitation projects, or where future development is anticipated will be considered.
Deliverables for Task 3.1:
• Flow monitoring plan detailing the basis of approach and implementation strategy for effective flow monitoring, including maps. (Electronic format) City of San Mateo 5

T
ask 3.2 – Meter Site Investigations (Now combined with Task 3.3) After the City’s review and approval of the draft flow-monitoring plan, Woodard & Curran’s flow monitoring subcontractor, ADS, will conduct a reconnaissance of the flow monitoring sites to confirm the locations are appropriate for monitoring from the standpoint of hydraulic conditions, safety, and access. ADS will also determine the appropriate meter type for the specific hydraulic conditions at each site (all gravity flow meters will be area-velocity type, capable of recording both flow depth and velocity).
Assumptions for Task 3.2:
• For purpose of estimating the budget for this subtask, 35 sites are assumed, with some of them assumed to be the same as in the previous system-wide flow monitoring program.
• City to facilitate access to any site locations, as needed. • City will be responsible for (or waive) encroachment permit fees.
Deliverables for Task 3.2:
• Site sheets showing proposed meter locations and flow conditions, including photographs and manhole sketches.
Task 3.3 – Conduct Flow Monitoring (Optional)
After approval of the flow monitoring sites and if the flow monitoring work is authorized by the City, ADS will obtain necessary permits and submit traffic control plans as required by the City.
ADS will then install, calibrate and maintain the flow meters for up to two months during the 2026/27 wet weather season (likely during the December/January/February timeframe, to be determined jointly by Woodard & Curran and City) and remove the flow meters at the end of the monitoring period. In addition, up to 5 recording rain gauges will also be installed to capture rainfall data during the flow monitoring period (if sufficient existing gauges are not available). ADS will upload the data remotely to its PRISM web-based data delivery system.
Woodard & Curran will review the flow monitoring data during the flow monitoring period to check data quality and consistency. ADS will provide final electronic data files (15-minute data) at the conclusion of the monitoring and a report including general description of the program, site reports, tabular summaries of the data, and graphs of flow depth, velocity and flowrate and rainfall for each meter. Analysis of the flow monitoring data to quantify infiltration/inflow (I/I) and develop design flows is an integral part of model calibration and system performance evaluation and will be conducted as part of Tasks 4 and 5.
Assumptions for Task 3.3:
• City will be responsible for (or waive) encroachment permit fees. • City to facilitate access to any site locations, as needed. • City staff to perform cleaning of the sewer line, if required. • Standard traffic control plans and basic traffic control will be provided truck-mounted light boards and 300-foot maximum cone tapers). City will provide additional traffic control if needed, or project budget will be adjusted to include preparation of site- specific traffic control plans and/or additional traffic control services if required by City.

Task 4 – Hydraulic Model Development
T
ask 4.1 – Update Hydraulic Model and Network
The model update process will start with the City’s existing hydraulic model. Woodard & Curran will also import the City’s sewer GIS data directly into the InfoWorks model database to create an “all-pipe” network in ICM. Unmodeled sewers will be added to the model network, as well as any recent improvements that may not yet have been incorporated. A QA/QC process called “model validation” will be used to verify the data before beginning any model runs. This process includes checking network connectivity (using “tracing” routines in InfoWorks) and data completeness and reasonableness for apparent discrepancies (e.g., missing data, negative pipe slopes, outlet pipe invert elevations higher than inlet elevations, etc.). Missing or suspect data will be resolved through review of available record drawing, requested field verification, or making reasonable inferences. The source of any new or corrected data in the model will be documented directly in the model database using InfoWorks “flags” and notes, so that this information can be provided back to the City for updating its GIS files. Note that in a system such as San Mateo, where new high-density polyethylene (HDPE) sewers may have been installed in some areas, it will be important to identify pipe material in order to accurately attribute the correct inside diameter to each pipe in the model. Woodard & Curran will also discuss with the City whether or not lower ‘n’ values should be assigned to such pipes, rather than the standard ‘n’ of 0.013 typically used for sewer master planning evaluations. In general, Woodard & Curran recommends that the standard value be used, as the roughness of these newer pipes may be reduced over time due to accumulation of a “slime layer” on the pipe wall.
Each parcel is the City will be considered a “subcatchment” in the model, with its existing and future wastewater load determined based on the work completed under Subtasks 4.2 and 4.3. parcel loads will be assigned to the appropriate pipe in the model based on lateral GIS data (if available) or proximity. Information about each parcel used to determine its load (e.g., customer type, development name, number of dwelling units, etc.) will also be documented in user fields in the model database.
Assumptions for Task 4.1:
• Current InfoWorks® ICM hydraulic model files are up-to-date with respect to the sewer network (except for possibly recent improvements in the system and smaller diameter pipes that may not be included) and model loads are based on calibration conducted based on the 2018 flow monitoring data and any updates made since that time under the CWP.
• GIS data is reasonably complete and includes invert data for most City-owned pipes.
Record drawing research or field investigations will not be necessary. • Up to 10 pump stations will be added to the model where needed. • Pump curves and wet well geometry for all pump stations will be provided by the City, or pump stations will be modeled as pass-through pump stations. • Hydraulic model will be updated to the latest version of InfoWorks ICM. Woodard & Curran will use its own software licenses for the modeling work.
Deliverables for Task 4.1:
• Documentation for this subtask will be included in the TM developed under Task 4.4.

T
ask 4.2 – Develop Existing Model Loads
Woodard & Curran will review existing data collected under Task 2 and discussions with City staff to determine the best approach for using this data to develop existing base wastewater flows. It is anticipated that sewer billing data or winter water use records will be the primary source of data for developing existing parcel loads, Winter water use will be summarized by customer category/land use type and also used to develop preliminary estimates of unit flow factors that can be applied to future parcel loads. (Flow factors will be validated through dry weather model calibration, as discussed under Subtask 4.4.) Assumptions for Task 4.2:
• City will assist Woodard & Curran in obtaining water use records from Cal Water.
Deliverables for Task 4.2:
• Documentation for this subtask will be included in the TM developed under Task 4.4.
Task 4.3 – Develop Future Model Loads
Based on information collected and discussions with City planning staff under Subtask 2.2, Woodard & Curran will tabulate future land use information at the parcel level, drawing upon the various available sources of information described in that task. The parcel-based land uses and flows developed in this subtask will be compiled in a GIS database for use in developing model loads.
Assumptions for Task 4.3:
• City staff will provide development information (“projects in the pipeline”) and Housing Element sites in a spreadsheet, geodatabase or shapefile format, with associated APNs.
General plan data will be provided in a shapefile or geodatabase format.
Deliverables for Task 4.3:
• Documentation for this subtask will be included in the TM developed under Task 4.4.
Task 4.4 – Calibrate Model
Woodard & Curran will use the flow monitoring data collected as part of this study to calibrate the hydraulic model. The model will first be calibrated for dry weather flows to confirm the base wastewater flow estimates developed under Subtask 4.2, as well as to refine diurnal wastewater profiles and non-rainfall groundwater infiltration (GWI) rates. GWI is estimated based on the difference between model-simulated base wastewater flows and observed flows at the meter sites and expressed as a unit areal flow (gpd/acre) distributed uniformly to the meter tributary area. Wet weather parameters will be determined for each flow meter tributary area based on calibration to monitored storm events. After calibration of the hydraulic model developed in the previous sub-tasks, a Hydraulic Model Technical Memorandum, including documentation of the basis for the model network update, development of existing and future model loads, and model calibration will be provided.
Assumptions for Task 4.4:
• Workshop will be scheduled prior to the submittal of the Technical Memorandum Deliverables for Task 4.4:

• Hydraulic Model Draft Technical Memorandum. (Electronic format). Comments to be incorporated in the final report
• Final files in the determined file format with all flow scenarios will be provided at the conclusion of the study.
Task 4.5 – Model Software Evaluation & Training (Optional) InfoWorks modeling software has served the City well for over 20 years. While we do not feel that there would be any benefit to the City in switching to a different program, we will assist the City in evaluating other software options should it wish to consider them. Our team has licenses and direct experience with several other fully-dynamic modeling programs including AquaTwin Sewer and SewerGems and can assist the City in evaluating those programs and obtaining the necessary model software for City use if desired. Additionally, Woodard & Curran will train City staff to use the selected software (or in InfoWorks ICM), including multiple training sessions and materials.
Assumptions for Task 4.5:
• Purchase of software license is not included and is assumed it will be purchased by the City.
• A total of four (4) training sessions will be provided Deliverables for Task 4.5:
• Software Evaluation Technical Memorandum
• Training materials (Electronic format)
Task 5 – System Performance Evaluation and Improvement Needs T
ask 5.1 – Develop Design and Hydraulic Criteria
Woodard & Curran will propose appropriate design and hydraulic criteria to be used for assessing the capacity of existing sewer facilities and sizing new facilities, including pipe friction factors, maximum flow depth to diameter (d/D) ratios, minimum and maximum velocities, slopes, depth of cover, and pump station design and reliability considerations (e.g., firm capacity, efficiency, emergency storage). Additionally, Woodard & Curran will review the City’s existing design criteria as compared to industry and other agencies’ standards and propose an appropriate design storm to be used for assessing system capacity, and criteria for evaluating the performance of the system under the design event based on the City’s desired level of service and risk acceptance. A draft Technical Memorandum will be prepared to provide background information and recommendations for the City to review and serve as basis for discussion at a workshop to review and reach agreement on the criteria.
Deliverables for Task 5.1:
• Design Flow and Hydraulic Criteria Draft Technical Memorandum (to be incorporated as a chapter in the final report)
Task 5.2 – Evaluate Sewer System Performance
Using the hydraulic model, Woodard & Curran will evaluate the performance of the existing sewer system under existing and future dry and design wet weather flows. This includes City of San Mateo 9
Sanitary Sewer Master Plan Update
June 24, 2026
identifying the capacity deficiencies based on the performance criteria and preparing thematic maps and hydraulic grade line plots to present the identified capacity problem areas.
Deliverables for Task 5.2:
• Thematic maps and hydraulic profiles of model results Task 5.3 – Conduct I/I Analysis
Woodard & Curran will review the I/I flow characteristics associated with the different subbasins in the system (based on flow monitoring data and model results) and their location with respect to identified capacity deficiencies. Based on the analysis, areas that may be suitable for rehabilitation to further reduce I/I will be identified.
Subsequently, Woodard & Curran will develop estimates of the percent I/I reduction that can be achieved through rehabilitation of various combinations of mains, lower laterals, and upper laterals and provide recommendations on how best to reduce I/I from private properties. The I/I reduction estimates will then be incorporated into the hydraulic model to determine the effects of the rehabilitation alternatives on peak flows.
Deliverables for Task 5.3:
• Results will be included in the Task 5.5 Technical Memorandum Task 5.4 – Conduct WWTP Alignment Analysis
Woodard & Curran will review the available documentation from the CWP to determine how previous analyses and assumptions align with the current operational demands, projected future growth, and evolving regulatory requirements under the Clean Water Program and regional initiatives such as the Pure Water Peninsula Project. This task will integrate evaluation of liquid treatment processes, solids and biosolids systems, and supporting infrastructure to identify gaps, risks, and opportunities for optimization and improvement.
The WWTP Alignment Analysis will include the following key elements:
• Existing Conditions and Capacity Assessment
o Assess liquid and solids treatment unit capacities relative to current flows and loadings
o Assess system redundancy, reliability, and operational constraints o Review performance relative to permit limits and operational targets • Regulatory Alignment Evaluation
o Assess compliance with existing requirements, including NPDES permit conditions, Title 22 recycled water criteria, and biosolids regulations o Evaluate readiness for anticipated regulatory changes, including:
San Francisco Bay nutrient reduction requirements
Emerging contaminants (e.g., PFAS)
SB 1383 biosolids diversion and reuse requirements
o Identify compliance gaps and areas of regulatory risk • Future Flow and Load Projections
o Evaluate hydraulic and organic constituent loadings (nitrogen, phosphorus) and capacity under dry and wet weather flow conditions.
City of San Mateo 10
Sanitary Sewer Master Plan Update
June 24, 2026
o Review solids and biosolids processing facilities under future growth scenarios (thickening, stabilization, dewatering, storage and hauling) • Alignment Analysis (Capacity, Compliance, and Flexibility) o Evaluate the current WWTP facilities and operations to verify and establish baseline performance and capacity.
o Compare projected conditions to existing process capacities o Evaluate the ability of existing facilities to meet future effluent and biosolids requirements.
o Assess WWTP flexibility to support recycled water expansion and regional reuse initiatives
Additionally, Woodard & Curran will provide recommendations for the improvement or additional studies of the WWTP facilities, including the liquid and solid processing operations.
The analysis will need to include the capacity of the current use and future growth needs, as well as the future regulatory compliance criteria set by the state that are expected to go into effect in the next decade, if not captured in previous studies.
Assumptions for Task 5.4:
• Analysis will be conducted at a planning-level and will rely on available data, reports, and City input.
• The City will provide access to relevant documentation, including prior studies, Clean Water Program deliverables, design reports, operational data, permit records, and biosolids management information.
• Existing flow, loading, and operational data provided by the City are assumed to be accurate and representative of current conditions.
• The scope does not include pilot testing or new monitoring programs. • Site visits and workshops will be limited to those reasonably necessary to support the analysis; extensive field investigations are not included. • Workshop will be scheduled following the submittal of the Technical Memorandum Deliverables for Task 5.4:
• WWTP Alignment Analysis Technical Memorandum (Electronic format) Task 5.5 – Develop Capacity Improvement Projects
Woodard & Curran will develop solutions to identify capacity deficiencies. Alternative solutions may include upsizing or paralleling existing pipes, consolidating flows in new sewers or existing sewers with available capacity, implementing flow diversions at critical locations, or sewer rehabilitation to reduce I/I. Potential alternatives will be developed based on hydraulic modelling results. Based on preliminary model results and discussion with City staff, the alternatives will be refined and focused on the most viable solutions for more detailed project development.
After the alternatives are refined, Woodard & Curran will evaluate potential improvement projects in further detail, including reviewing potential project alignments in Google Maps or, if needed, conducting field visits to potential project sites to confirm the suitability of pipeline alignments and identify any design, constructability, permitting, or environmental issues that City of San Mateo 11
Sanitary Sewer Master Plan Update
June 24, 2026
might impact the projects. Planning level cost estimates will be developed based on the most viable construction method for each potential solution for the identified deficiencies.
Assumptions for Task 5.5:
• Workshop will be scheduled following the submittal of the Technical Memorandum Deliverables for Task 5.5:
• Sewer System Capacity Analysis & Results Technical Memorandum summarizing results of Tasks 5.2, 5.3, and 5.5. (Electronic format)
Task 6 – Condition Assessment and Rehabilitation/Replacement Program T
ask 6.1 – Perform Gravity Sewer Condition/Risk Assessment Woodard & Curran’s subconsultant, VW Housen & Associates, will review the CCTV inspection database and reports provided by the City and provide recommendations for improvements to data collection methods (observation coding, segment identification, database management, QA/QC review procedures) for the City’s ongoing CCTV inspection program. Recommendations will be provided for improvements to data collection methods from the City’s Operations & Maintenance staff to streamline the use of this data for input into the risk analysis/CIP development. Observations and recommendations will be discussed with the City and later incorporated into the Gravity Sewer Condition Assessment TM.
The City’s CCTV, GIS, and available maintenance history data will be used along with other risk factors to develop a risk score for each gravity pipe in the collection system. The risk assessment will be based on a combination of Likelihood of Failure (LOF) based on CCTV inspection data, sewer material and age, and other relevant factors (e.g., maintenance history); and Consequence of Failure (COF) based on potential impacts on the environment (proximity to water bodies) and community (traffic, land uses, etc.). The risk assessment methodology will be designed to support the City’s strategies for near- and long-term rehabilitation or replacement. Where CCTV data is not available (approximately 10 percent of the system was not inspected as part of the CWP), a method for surrogate scoring (typically based on sewer material and age) could be used to identify pipes that should be prioritized for CCTV inspection. The results will be reviewed with City staff. Based on the results and with input from City staff, minor refinements to the risk calculations may be made if needed.
Assumptions for Task 6.1:
• CCTV data is provided in a single consolidated NASSCO PACP export database which can be linked to the City’s sewer GIS based on manhole and pipe IDs. This task does not include any data compilation, analysis, or cleanup.
• Data needed for risk analysis (e.g., pipe age/installation date, material, maintenance frequency; land use or parcel use GIS mapping; GIS mapping of water bodies and drainage) will be provided by City.
Deliverables for Task 6.1:
• Workshop Materials
6.2 – Develop Sewer R/R Decision Process and Develop R/R Plan City of San Mateo 12
Sanitary Sewer Master Plan Update
June 24, 2026
Woodard & Curran and VW Housen & Associates will collaborate with City staff to develop a documented and objective decision process along with recommended methods to identify the specific defects requiring maintenance, repair, or rehabilitation/replacement (R/R). The risk scores developed in the previous step will be incorporated into the rehabilitation decision as well as an analysis of the type of defects, the quantity of each type of defect, the severity of the defects identified in each pipe segment based on the CCTV inspection data, and general constructability constraints. (Note that pipes found to be in good condition, such as those already replaced under the City’s rehabilitation program, will generate a “maintain” decision in this process.) Input from City staff on the proposed risk assessment and rehabilitation decision methodology will be solicited at a workshop before finalizing the analysis process.
The process developed in Subtask 6.2 will generate initial repair, rehabilitation, and replacement recommendations based solely on analysis of defect data and pipe risk scores, with consideration of constructability and access. The initial repair, rehabilitation, and replacement decisions will be linked to the sewer GIS and generate maps displaying condition ratings and the results. These results will be reviewed with the City and the segments identified for rehabilitation or replacement will be grouped into logical projects and prioritized based on a combination of risk scores, R/R method, and location. The projects will be incorporated into the sewer system capital improvement plan in Task 8.
Assumptions for Task 6.2:
• This task includes one additional iteration of the risk model to refine priorities, CIP objectives, and finalize the R/R CIP
Deliverables for Task 6.2:
• Gravity Sewer Condition Assessment and Rehabilitation Plan Technical Memorandum Task 6.3 – Pump Station Condition Assessment and Improvement Plan Woodard & Curran will perform a condition assessment of the City’s pump stations. First, Woodard & Curran will review existing available plans, pump specifications, and operation and maintenance records for the City’s pump stations. Then, we will meet with City staff to discuss any current issues with respect to capacity, operations, or condition, which will be followed by site visits to visually assess the stations. W&C will develop an Engineer’s Opinion of Probable Cost (EOPC) to replace the equipment deemed to be past its useful life or that is otherwise broken, unreliable, or poses a threat to health and safety. The findings and identified improvement needs based on the information review and field visits will be incorporated into a Pump Station Condition Assessment Technical Memorandum, which will be incorporated into the Sewer System Master Plan Update.
During the first step of the condition assessment process, Woodard & Curran will review the existing data to determine which of the pump stations have been recently rehabilitated under the Clean Water Program. These Pump Stations will not require a site visit.
Improvement needs will be determined by the following methods:
• Equipment reported to be broken, unreliable, or malfunctioning by City staff • Equipment or site features noted to be in poor condition or that present a danger to the public heath and safety, for example severely rusted or damaged equipment; broken concrete or uneven surfaces resulting in potential slips, trips, and falls; unstable City of San Mateo 13
Sanitary Sewer Master Plan Update
June 24, 2026
walls or fences; and wet well features like hatches, ladders, harness connections, and platforms.
• Equipment at or nearing its Remaining Useful Life (RUL). Age of equipment/systems will be calculated by one of the following methods depending on available data:
o Assume that equipment dates to the most recent record drawings that included the equipment.
o Specific installation year or timeframe if known by City staff. o Operators’ estimate of asset age.
o Estimated age/remaining life based on apparent condition Assumptions for Task 6.3:
• The City owns and operates 26 wastewater pump stations. All 26 pump stations will be included in the study and Technical Memorandum. It is assumed that 8 pump stations have recently been rehabilitated or are already planned to be rehabilitated under the old Clean Water Program. Therefore, a total of 18 pump stations will be assessed via a site visit
• The site visits will take place over 3 days, assuming 6 stations can be visited in one 10- hour day
• Meeting to discuss known issues with City staff will include City O&M personnel and will be conducted virtually
• City O&M staff will accompany Woodard & Curran to each pump station to provide access to the sites and will open panels, hatches, etc. to facilitate visual inspection • EOPC will conform to the Association for the Advancement of Cost Engineering (AACE) International Recommended Practice 17R-97, Class 5. Costs will be developed for equipment deemed to be past its useful life or that is otherwise broken, unreliable, or poses a threat to health and safety. A cost for a comprehensive pump station rehabilitation project will not be provided.
• Destructive and non-destructive testing is not included • Electrical inspection such as insulation check, resistance of contacts, and control device operation is not included
• Assessment of electrical equipment will be limited to visual checking and photographs of signs of wear, corrosion, flashover/carbon deposits, age, and Electrical Code clearances. Assessment is not intended to be an inspection of the facilities for Code compliance. However, if Electrical Code issues are observed, they will be incorporated into the assessment report.
• Review of control system logic and control strategies is not included. • The condition assessment does not include a load study, short circuit rating confirmation, device coordination review, or Arc Flash Study. • Structural observation does not include evaluation or calculations to verify seismic capacity or expected seismic performance of structures or pump station components. • Woodard & Curran will not enter any OSHA-defined confined spaces, which may include wet wells and dry wells. Should entry into such spaces be required to complete an asset assessment, Woodard & Curran will rely on photos/videos provided by the City. • Woodard & Curran will not operate any equipment or open electrical panels. If operator(s) can safely operate equipment and open such panels for observation, City of San Mateo 14
Sanitary Sewer Master Plan Update
June 24, 2026
Woodard & Curran will include observed conditions in its assessment. Use of specialized arc rated PPE by Woodard & Curran will not be required. • Geotechnical site investigation is not included at any of the pump stations as a part of this Subtask.
• No additional flow monitoring, system modeling, or pump analysis will be conducted. • Information required for the evaluation will be requested under Task 2 • The Draft Technical Memorandum will include a summary of the data review, meeting with City staff, site visits (including pictures), RUL, recommendations for replacement, and EOPC
Deliverables for Task 6.3:
• A Draft Technical Memorandum that summarizes the findings will be submitted for City review. The comments will be addressed and a Final version will be included in the Sewer Master Plan Update
Task 6.4 – Force Main Study and Inspection Plan
This task involves the review and desktop study of approximately 11.5 miles of force main located within the City and 1.9 miles of outfall from the WWTP. The desktop study will be summarized in a Force Main Inspection Plan. The purpose of the desktop study and inspection plan is to consolidate key information for each force main that would be needed for the City, consultants, and vendors to accomplish the following in a practical and efficient visual manner:
• Understand and discuss the age, material, and performance issues for each segment of force main.
• Understand existing access constraints and distances between force main access points for comparing against available inspection technologies deployment and retrieval needs, and inspection length capabilities
• Understand necessary shutdown and bypass operations needed to isolate force main sections for replacement and/or inspection of incremental force main sections, which may also consider the installation of permanent isolation valves and other features to facilitate an ongoing program
• Preparation of force main maps to provide available existing information for each force main that may be used to help plan for and define future force main inspection projects and rehabilitation or replacement projects identified after inspections have been completed.
• Develop an inspection plan for newer or newly replaced force mains for continued maintenance of the network
• Develop an EOPC for recommended force main inspection program • Develop a separate EOPC for recommended force main rehabilitation/replacement costs (see Assumptions for Task 6.4)
Prior to beginning the Force Main Study and Inspection Plan, Woodard & Curran will meet with City staff, including O&M personnel, to discuss any current performance issues with respect to capacity, operations, or condition. Force mains will be characterized by things like age, material, location, geometry, soils, repair history, and pressure fluctuations, assuming this information is provided to W&C by the City. This information will suggest how to prioritize inspections and will provide insight into possible inspection methods (i.e. CCTV, internal investigation methods, or external testing) and frequency.
City of San Mateo 15
Sanitary Sewer Master Plan Update
June 24, 2026
A
ssumptions for Task 6.4:
• The City does not have condition assessment data for its force mains, hence the need for a Force Main Inspection Plan. Therefore, the requested recommendations and estimated costs for rehabilitation and replacement will be based solely on the age and material determined from the available record drawings, the performance issues communicated by City staff, and information within available maintenance records. • Engineer’s Opinion of Probable Cost will conform to the Association for the Advancement of Cost Engineering (AACE) International Recommended Practice 17R-97, Class 5
• Meetings with City staff will be conducted virtually
• City will provide relevant data regarding the force mains. At a minimum, this is expected to include record drawings and maintenance records but may include geotechnical reports and flow and pressure data.
• Woodard & Curran will not participate in field testing of force mains, design of bypasses, or calculations for allowable pump station shutoff time. However, Woodard & Curran will provide estimated cost of recommended field testing for each force main studied.
• For force mains, if field testing is conducted, Woodard & Curran (per separate contract) will review the results of pipeline testing performed by others and assess apparent force main condition based on this data. Data is expected to include, at a minimum, photographic data and in-situ pipe wall thickness. If data is inconclusive, Woodard & Curran may recommend additional testing. If data conclusively demonstrates poor force main condition, Woodard & Curran may recommend additional testing to determine the extent of the issue or may include a cost estimate for repair depending on the presumed extent of the concern. The approach will be determined by the quality of the testing data and the specific force main configuration.
Deliverables for Task 6.4:
• A Draft Force Main Inspection Plan that summarizes the findings will be submitted for City review. The comments will be addressed and a Final version will be included in the Sewer Master Plan Update
Task 7 – Seismic Vulnerability Assessment
T
ask 7.1 – Seismic Vulnerability Assessment
TYLin will perform a planning-level seismic vulnerability assessment of all (26) pump station facilities, including wet wells, valve vaults, and associated above-grade enclosures. The evaluation will be based on review of available documentation (e.g., as-built drawings, prior studies), supplemented by site visits to pump stations to confirm general structural configurations and observe accessible conditions.
The assessment will utilize a screening-level methodology, drawing from applicable provisions of the California Building Code (CBC), California Existing Building Code (CEBC), and ASCE 41 Tier 1 procedures, as appropriate. The evaluation will focus on key drivers of seismic vulnerability, including:
• Soil-structure interaction and geotechnical hazards (based on geotechnical input) City of San Mateo 16
Sanitary Sewer Master Plan Update
June 24, 2026
• Groundwater conditions and buoyancy effects on below-grade structures • Structural capacity of wet wells, vaults, and small above-grade buildings • Pipe penetrations and structural interfaces
• Anchorage of mechanical and electrical equipment
Pump stations are assumed to be small-scale facilities as described above, and the evaluation will be performed at a screening level consistent with master planning objectives. Detailed structural analysis, nonlinear modeling, and design-level evaluations are not included.
In addition, TYLin will perform a high-level, desktop seismic screening assessment of select solids processing facilities at the wastewater treatment plant (assumed on the order of 5 to 7 structures). The evaluation will be based on available ratings and prior documentation and will follow a screening-level methodology consistent with the pump station assessments. Our Team will also evaluate major sewer mains for potential seismic risks, with a primary focus on pipe material characteristics including ductility and strength, as well as the proximity of pipelines to geographically poor soil conditions, including bay mud areas, which may increase the likelihood of pipeline failure during seismic events.
This effort is limited to a desktop review; site visits, visual condition assessments, confined space entry, and detailed structural analysis of wastewater treatment plant facilities are not included.
Evaluation is limited to major solids processing structures and does not include detailed review of process equipment, piping systems, or liquid treatment facilities. The outcome will include identification of key seismic vulnerabilities and conceptual recommendations to support capital improvement planning and prioritization.
The seismic evaluation is intended to be screening-level and qualitative in nature; detailed structural calculations, nonlinear modeling, and design-level analyses are not included.
Geotechnical Subconsultant
TYLin will retain a geotechnical subconsultant to support the structural assessment with a planning-level evaluation of site conditions and seismic hazards. The geotechnical scope will include review of available geotechnical reports, regional geologic mapping, and published hazard data to characterize site class, liquefaction susceptibility, surface fault rupture, lateral spreading potential, seismic settlement, and groundwater conditions, including potential buoyancy effects on below-grade structures. This effort will be limited to a desktop-level screening intended to inform the structural vulnerability assessment and prioritization of improvements. Subsurface exploration, field investigations, laboratory testing, and detailed geotechnical analyses are not included. It is assumed that sufficient publicly available data and prior studies exist to support this screening- level evaluation; no new subsurface investigation will be performed.
Cost Estimator Subconsultant
TYLin will retain and coordinate with a cost estimating subconsultant to develop planning- level construction cost estimates for recommended structural improvements to support development of the Capital Improvement Program (CIP). The cost estimator will be responsible for preparing opinions of probable cost based on conceptual improvement strategies and available project City of San Mateo 17
Sanitary Sewer Master Plan Update

information. TYLin will provide supporting input, including conceptual retrofit approaches, key cost drivers, and relevant quantities at a high level, to inform the estimating effoi1. Detailed quantity takeoffs, unit pricing development, and preparation of engineer’s estimates beyond planning- level opinions of probable cost are not included in TYLin's scope.
Assumptions for Task 7.1:
• City staff will accompany TY Lin to each pump station to provide access to the sites and will open any panels, hatches, etc. to facilitate visual inspection • Workshop will be held after the submittal of the draft Report Deliverables for Task 7.1:
• Seismic Vulnerability Assessment Report (to be incorporated into the Sewer Master Plan Update)
Task 8 – Long-Range Capital Improvement Plan Development T
ask 8.1 – Prioritize Capacity & Rehabilitation Projects Woodard & Curran will prioritize the recommended capacity improvement and rehabilitation projects. For capacity improvement projects, prioritization criteria will include severity of existing capacity deficiencies as indicated by the extent of surcharge or potential overflows predicted by the model, as well as:
• Potential impact on public health and safety, water quality, business and community facilities, etc.
• Timing of proposed development/redevelopment
• Maintenance history and/or sewer condition information • Coordination with other City projects (e.g., road improvements) Sewer and pump station rehabilitation projects will be prioritized based on condition (structural and maintenance) and risk level, as well as reliability (including seismic vulnerability).
Deliverables for Task 8.1:
• None
Task 8.2 – Develop Phased CIP
Woodard & Curran will use the City’s historical cost data as well as costs from other Bay Area sewer improvement projects to develop unit cost criteria for the various components of sewer construction, including pipeline and lower lateral replacement (via pipe bursting, open cut, and other applicable trenchless methods), as well as other cost factors associated with construction in urban areas. We will also work with the City to develop appropriate cost allowances for engineering, construction administration, legal and permitting costs based on the City’s experience.
Based on the cost criteria, Woodard & Curran will develop project-specific opinions of probable construction and capital costs for the recommended capacity improvement and sewer and pump station rehabilitation projects developed in Tasks 5 and 6.
City of San Mateo 18
Sanitary Sewer Master Plan Update
June 24, 2026
Based on the project prioritization developed in Task 8.1, Woodard & Curran will develop a phased Capital Improvement Plan (CIP) for short-term (10-year) and long-term (20-year) sewer improvements. The phasing will also consider the City’s financial constraints and include recommendations for low, medium, and high levels of investment for CIP duration terms.
Assumptions for Task 8.2:
• City to provide annual budget targets for the CIP
Deliverables for Task 8.2:
• Up to three Sewer System CIP schedules (to be incorporated into the Sewer Master Plan Update)
Task 8.3 – Evaluate Funding Strategies
Woodard & Curran will work with the City to define funding from a combination of the following sources:
• Pay as you go cash reserves
• Outside loan and grant funding (both State and Federal), and • Issuance of bonded indebtedness.
These funding scenarios will be able to illustrate to City management and Council the magnitude of cash flow requirements by scenario so that rate and fee impacts can be estimated using the City’s rate and fee models during annual budgeting.
Task 9 – Sewer Master Plan Update Preparation
T
ask 9.1 – Draft Sewer Master Plan Update Report
Woodard & Curran will incorporate the methodology, findings, and recommendations of the study into a comprehensive Sewer Master Plan Update report. The report appendices will contain supporting data including flow monitoring data plots, model calibration graphs, model data and results tables, sewer and pump station condition assessment data and rehabilitation/replacement recommendations, force main study and inspection plan, detailed project cost estimates and maps, and other pertinent information. The report will include an Executive Summary section that can be extracted as a stand-alone document and provided to City officials or other interested parties. The Seismic Vulnerability Report will be included as an appendix to the Master Plan; however, the recommendations of that report will be incorporated into the Master Plan. The Sewer Master Plan Update will serve as a basis for future master plan updates.
