5 Section B Introduction and Approach Wastewater Collection System Hydraulic Modeling and Master Plan Development Services B. Introduction and Approach

6 Section B Introduction and Approach Project Understanding The Town of Los Altos Hills (Town) is initiating preparation of an updated Wastewater Collection System Master Plan in order to assess the capacity needs of its sanitary sewer system. The Town s last Master Plan was prepared in 2004 based on limited flow monitoring data and a rudimentary, spreadsheet-based hydraulic model. The updated Master Plan will be based on a new state-of-the-art dynamic hydraulic model of the system calibrated to flow monitoring data collected during this past winter season. The model will allow the Town to more accurately determine its current and projected future flows, assess the capabilities of its existing collection system, and identify any capacity improvements needed to adequately serve its residents. In recent years, the Town has taken a number of proactive steps to develop a comprehensive program for effective operation, maintenance, and capital planning of its collection system: + + Developed a geographic information system (GIS) database linked to a computerized maintenance management system (CMMS) to inventory its system assets and schedule and track maintenance activities + + Implemented a closed-circuit television (CCTV) inspection program to document the condition of the sewers and identify rehabilitation/replacement (R/R) needs + + Developed a risk model to prioritize system improvements The capacity assessment of the system to be conducted as part of this Master Plan study will be an important element of this overall program. Land uses within the Town are predominantly single family residential (there are only 14 non-residential connections, City of Palo Alto counting the six Town facilities). While growth within the Town limits has been relatively modest (average of about 11 new residential units per year between 2007 and 2014), the Town s wastewater collection system currently serves only about half of the approximately 3,000 developed parcels, with the remainder served by on-site septic systems. Since one of the Town s goals is to ultimately provide public sewer service to all of its residents, there may be a significant increase in flows in the future. Confirming the adequacy of the system to handle these flows will be an important part of this Master Plan. The Town currently has agreements with the Cities of Los Altos and Palo Alto to convey its flows through their systems to the Palo Alto Regional Water Quality Control Plant. The Town s system discharges into the Los Altos and Palo Alto systems at seven separate locations. None of these locations is currently Sanitary Sewer Line Outlet Pipes Streets/HWY City of Palo Alto Palo Alto Basin Los Altos Basin Town Boundary The Sewer Master Plan will help quantify the dry and peak wet weather flows discharged to Los Altos and Palo Alto. City of Los Altos Wastewater Collection System Hydraulic Modeling and Master Plan Development Services B.1

7 Introduction and Approach < < RMC Water and Environment metered, and the Town s contractual agreements with the two cities to convey its wastewater flows are based on the number of connections and assumed flow per connection. Therefore, it is critical for the Town to have an accurate assessment of its current and projected future flow discharged to each city. Both agreements reference a limit on peak wet weather flow, although without metering, such a limit cannot easily be enforced. However, in the interest of minimizing downstream impacts, as well as impacts in its own system, controlling peak wet weather flows is also an important planning objective for the Town. Key objectives of this Master Plan are: + + Accurately quantify both existing and future flows + + Determine the capability of the existing sewer system to handle projected flows, including new connections due to growth and connection of septic parcels + + Identify required sewer improvements to provide needed capacity and estimate costs + + Prioritize improvements based on timing of new connections and extent of capacity deficiencies Project Approach RMC s approach to developing the Master Plan will provide an accurate hydraulic model that can be used effectively to assess the existing and future capacity needs of the Town s wastewater collection system. The key elements of our approach are summarized in the table below and discussed in the paragraphs that follow. In the appendix, we have also included a more detailed scope of work that can serve as a basis for initiating contract negotiations should RMC be selected for this project. RMC agrees to the terms of the Town s standard consulting services agreement.

8 RMC Water and Environment > > introduction and Approach Verifying Current Wastewater Flows Is Critical for an Accurate and Believable Capacity Analysis Flow estimates and projections form the fundamental basis for all capacity improvements recommended in sewer collection system master plans. RMC s approach emphasizes the importance of accurately estimating dry and wet weather flows from the start. + + Use parcel-level billing and water consumption records to estimate current base wastewater flows. We have found that developing base wastewater flows at the individual parcel level captures variations among users and results in the most accurate flow estimates possible. In many of our recent projects, we linked parcel GIS mapping, water use data, customer billing records and parcel land use data to develop average base wastewater flows for each parcel. For instance, for our projects for the cities of San Mateo, San Carlos, Santa Clara, Hayward, San Leandro, Berkeley, Pacifica, Daly City, and Hillsborough, among others, we used actual water consumption data at the parcel level (taken from wet months to minimize the outdoor water use adjustment required) to develop very precise estimates of flows from residents and businesses for both existing and future conditions. Our methodology provides the flexibility to tailor this approach to the particular format and availability of each agency s data. For Los Altos Hills, we will use the Town s database of sewer connections (identifying both single family residential dwellings as well as second units) and water use data from the Purissima Water District and Cal Water (if available) to develop initial estimates of parcel flow contributions. + + Verify unit flow rates and quantify groundwater infiltration and wet weather flow response using flow monitoring data and rigorous model calibration. Regardless of the method used to estimate current flows, accurate flow monitoring data is critical for calibrating and verifying the base wastewater flows and also for estimating the I/I characteristics throughout the system. The data from the 12 meters installed for the Town s flow monitoring program this past winter will be used effectively to confirm existing system flows. For the City of Berkeley, we estimated wastewater flows by parcel using water consumption data and parcel-based projections of future development. In RMC s experience, parcel-based information provides the most accurate wastewater flow estimates for hydraulic modeling. Accurate flow estimates and good flow monitoring data come together during model calibration. We use the flow monitoring data to ensure flow routing is correct and to adjust and verify base wastewater flow unit factors, diurnal flow patterns, groundwater infiltration, and the volume and routing of rainfall-dependent I/I until a good match is achieved between the model and the flow monitoring data. This process forms a sound technical basis for system capacity and I/I analyses. The graph shown here illustrates the model calibration for a meter in the Orinda area of CCCSD. In the graph, the green line represents the monitored (observed) flow and the brown line is the model-simulated flow, with the rainfall shown in blue above. RMC successfully calibrated an InfoWorks ICM model to 70 flow meters in CCCSD for the same flow monitoring period in February/March 2016 as the Town s program.

9 Introduction and Approach < < RMC Water and Environment Future Flow Projections Should Incorporate the Best Available Information on Anticipated New Sewer Connections and Unit Flows Although the Town is not anticipating significant growth in the future, the connection of existing parcels currently served by on-site septic systems will impact future sewerage needs. Furthermore, quantifying the increase in sewer connections by basin (Los Altos versus Palo Alto) will also be important for ensuring compliance with the Town s capacity allocations in those systems. As with existing flows, the challenge is to define the future scenarios at the parcel level and to forecast unit flows accurately. + + Use information from the latest Housing Element Update and input from Town planning staff to identify areas of potential new residential units. The Town s latest Housing Element Update estimates that it will meet its regional housing allocation goals through construction of new single family homes and second units (plus on-site housing at Foothill College, which is provided sewer service by the City of Los Altos). The historical trend of approximately six new single-family units per year is likely to continue, but construction of second units is projected to increase to about 10 new units annually. The Housing Element identifies 134 potential sites with the potential for 185 to 356 units on vacant or underutilized parcels. We will also consult with Town planning staff to identify the most likely locations for new units and probable timing. + + Identify septic parcels that may connect to sewer system in the future. The Town s database identifies developed parcels that are currently on septic systems. RMC will work with the Town to estimate the anticipated rate of connection of these parcels, and the areas likely to connect within the next five to ten years. The detailed information on current unit flow rates developed based on current water use and flow monitoring data will be used to estimate flows from these new connections, as well as a realistic assessment of potential future changes in post-drought unit rates. The Town s Housing Element identifies locations of potential new residential connections. Source: Town of Los Altos Hills General Plan Housing Element Update , Appendix F-2. A Fully-Dynamic Hydraulic Model Will Identify Current and Future Sewer Capacity Deficiencies and Needs Master planning for municipal sewer systems has evolved over the years toward fully-dynamic hydraulic modeling, which provides the most accurate representation of flows and hydraulics for quantifying the true risk of sanitary sewer overflows. The Town recognizes this, and has called for use of InfoWorks ICM modeling software for this project. RMC has extensive experience using InfoWorks (both ICM and its predecessor CS versions), and have completed over 40 projects using this software. We have five network software licenses for InfoWorks, which are shared by approximately eight experienced sewer system hydraulic modelers throughout our company. + + Develop a robust hydraulic model using InfoWorks ICM fully-dynamic hydraulic modeling software. The Town s wastewater collection system includes approximately 56 miles of 6- through 12-inch diameter pipelines and two sewage lift stations. A typical trunk system hydraulic model would normally include 15 to 25 B.4 Town of Los Altos Hills

10 RMC Water and Environment > > introduction and Approach percent of the system (the model developed in the 2004 Master Plan included 140 pipe segments, which would appear to be less than 10 percent of the pipes). The Town has an AutoCAD map of the system and has more recently developed GIS mapping of the system linked to asset IDs in the Lucity CMMS. We understand that the Town s sewer maintenance contractor, West Bay Sanitary District, has obtained survey data and populated the GIS with rim and invert elevations for the major sewers. RMC will import the GIS data into InfoWorks as the first step in developing the modeled sewer network. As part of our rigorous model validation process, RMC will review pipe profiles in the model and identify any suspect or missing data. We will work with the Town to verify or correct critical data through review of any available record drawings, requested field verifications, or inference (where reasonable). We will also use InfoWorks flags to document the source of any updated data, so that the Town can incorporate this information as it continues to update its GIS. RMC will use InfoWorks modeling tools to create profile plots of all modeled pipelines and will work with the Town to correct any potential data discrepancies. As discussed previously, we will calibrate the model to the data collected during the Town s 2016 flow monitoring program. Model calibration is an iterative process of progressively adjusting and refining model flow parameters (unit flow factors, diurnal patterns, I/I parameters) until a good match of modeled to monitored flows is achieved, which ensures that the model accurately represents the flows in the system and can be reliably used for capacity analysis. Criteria established by the international standard WaPUG Code of Practice for the Hydraulic Modeling of Sewer Systems are used as a guide for determining when the model is calibrated. The key WaPUG guidelines for model calibration include: Average and peak model flows for non-rainfall periods within +/- 10% of observed flows Model peak flows within +25% to -15% of significant wet weather peaks Modeled volume of flow within +20% to -10% observed volume of flow during rainfall event RMC has extensive experience calibrating hydraulic models for a wide range of flow conditions. For example, our recent work in calibrating CCCSD s model showed that while the March 5, 2016 storm produced the highest peak flows at most of the meters during the flow monitoring period as it also did in Los Altos Hills the later March storm events, although smaller, produced a much larger I/I response (per unit of rainfall) due to the saturated conditions, and even higher peak flows at some meters. Understanding the relationships between rainfall and I/I, which comes from experience, is key to achieving a well-calibrated model. + + Work with Town staff to establish risk-based criteria for design flows (including design storms) and hydraulic performance (allowable surcharge and freeboard). System performance goals must balance risk versus investment needs. These criteria provide a context for evaluating the collection system and determining where improvements need to be made. Establishing appropriate design flow and performance criteria is critical, as these decisions will directly affect both the cost of improvements recommended and the subsequent risk of failure. Performance issues include understanding: The impact the selected design storm has on the hydraulic evaluation The level of surcharge (i.e., risk of overflows) that is acceptable to the Town under a design event Wastewater Collection System Hydraulic Modeling and Master Plan Development Services B.5

11 Introduction and Approach < < RMC Water and Environment The Town has specified that a 10-year, 24-hour event should be used as the design storm for the Master Plan. This is a reasonable decision that is consistent with criteria used by a number of other San Francisco Bay Area agencies. However, the distribution of rainfall over the 24-hour period is also an important consideration. As shown in the adjacent figure, a distribution that creates a high peak hour intensity, as is typical of design events formulated Based on intensity-duration-frequency statistics ( nested storm ) or standard hydrology guidelines (such as an SCS distribution) may also have a significant impact on the flows generated by that event. The Santa Clara County Drainage Manual also defines a design storm which is largely based on historical rainfall patterns. This design storm pattern has been used for sewer master planning by several nearby cities, including the Cities of San Jose and Santa Clara. For any of these patterns, the actual magnitude (e.g., 24-hour volume) would vary based on location, typically related to mean annual precipitation. And in addition to the design storm rainfall, the peak design flow criteria must also specify the type of I/I response (e.g., maximum soil saturation?) and the timing with respect to seasonal groundwater and diurnal base wastewater flows that will generate the peak flows that the sewer system should be capable of conveying. These types of issues will be discussed with the Town to arrive at consensus on the appropriate design flow and performance criteria to use for the Master Plan. Another issue that will be addressed is the design event criteria used by Los Altos and Palo Alto, which may differ from the Town s. The Santa Clara County Drainage Manual defines a design storm pattern (above) that has been used for sewer master planning by other Santa Clara County cities. B.6 Town of Los Altos Hills The temporal rainfall distribution of the design storm can have a significant impact on peak flows. Capacity deficiencies and priorities should be based on the risk of overflows rather than simpler criteria such as percent of full pipe utilized. Agencies around the Bay Area use a variety of criteria, from allowing no surcharging at all to allowing a few feet of surcharging if sewers are sufficiently deep, to allowing the hydraulic gradeline to reach within a few feet of the ground surface under a design storm condition. RMC will work with the Town to establish appropriate performance criteria to ensure that deficiencies that are identified using the model reflect the Town s desired level of service and risk tolerance with respect to overflows. This is a key step to focusing limited resources on high-risk sewers and avoiding unnecessary expenditures. Develop and Prioritize CIP Projects Based on Risk Factors The final step in the capacity planning process is to develop and test solutions to identified deficiencies and prioritize those projects. Capacity projects identified should be both constructible and cost-effective. Our approach to developing the City s CIP ensures a practical program for capacity projects that prioritizes the most critical projects, and clearly identifies those projects required to eliminate the risks of capacity-related SSOs. + + Develop and model solutions that optimize use of existing sewers and minimize cost of improvements. RMC understands the difficulties and potential large costs associated with pipeline construction in challenging terrains such as Los Altos Hills. To help meet these challenges and develop realistic CIP cost estimates, our master

12 RMC Water and Environment > > introduction and Approach planning approach includes planning-level analysis of pipeline alternatives in critical areas to confirm constructability and evaluate cost-effectiveness. The right answer for any particular agency depends on system-specific conditions. For Los Altos Hills, where pipe sizes are small, pipe bursting to increase capacity may be a viable alternative in many areas, whereas re-routing pipelines may not be feasible due to the terrain. We will also incorporate any information available from the Town s sewer condition assessment and rehabilitation planning efforts to identify pipes that may need both increased capacity as well as rehabilitation to address structural deficiencies or maintenance issues (e.g., sags, root intrusion). quality, regulatory, community impacts, public perception, etc)? What would it cost to fix the problem? Reducing I/I through targeted sewer rehabilitation may also be an option for reducing the need for capacity improvements (and complying with potential downstream flow limits); but, achieving substantial I/I reductions has generally been shown to be difficult to achieve, particularly without addressing private service laterals. However, coordinating sewer R/R efforts for structural repair with targeted I/I reduction could be a feasible approach in some areas. Using the model, we will be able to estimate the overall reduction in I/I that may be required to eliminate the need for specific capacity projects. For example, for the City of Berkeley, we identified seven capacity relief projects that could potentially be eliminated by modest I/I reductions of 20 percent or less. + + Prioritize projects based on risk of wet weather overflows and need to accommodate future connections. The ultimate goal of the master planning process is to proactively identify capital projects that need to be constructed to meet system performance goals. Clearly prioritized projects will ensure that capital improvement dollars are spent where they are really needed and will provide the greatest value at the lowest cost. RMC uses a riskbased approach to prioritize recommended capital improvement projects. This approach considers the following to ensure that any risk is appropriately balanced with desired level of service: What is the likelihood of the event (e.g., overflows) occurring? What are the consequences of that event occurring (e.g. health and safety, water These model hydraulic profiles from the Orange County Sanitation District illustrate four sewers that vary greatly in terms of priority and risk of causing an overflow. The Town s new InfoWorks model will provide the type of information needed to make informed decisions about needed capacity improvements and priorities. Wastewater Collection System Hydraulic Modeling and Master Plan Development Services B.7

13 RMC Water and Environment > > introduction and Approach As noted previously, the use of a fully dynamic model that produces accurate hydraulic profiles and estimates of predicted overflow volumes is key in assessing a capacity project s priority, as it allows a realistic evaluation of the likelihood of a capacity deficiency to result in an overflow. Brief periods of surcharging during extreme wet weather events may be acceptable (or at least low priority) if the maximum water levels remain several feet below ground level. If the level of surcharging can be determined to present a low risk of overflow, a project to relieve the surcharging can be deferred or given a low priority for implementation, resulting in capital cost savings. In prioritizing projects, RMC will coordinate with Town staff and consultants who are involved in the development and application of the Town s risk model, to ensure that capacity needs are incorporated into the Town s overall risk-based capital planning process. Manage Project to Meet City Goals within Budget and Schedule Our team will implement our systematic approach to ensure your goals are met, all tasks are coordinated, and deliverables are submitted on time and within budget. + + Assign RMC s most experienced master planning engineers to key management and technical project roles. RMC believes the key to a successful project is an experienced, dedicated team. As demonstrated by our qualifications and references presented in later proposal sections, we are dedicating our master planning A Team to preparing the Los Altos Hills Master Plan. + + Communicate with Town staff regularly, and obtain input on key decisions at critical points in the project. Our project manager focuses on communication with the client and team members and sound project execution techniques to achieve a no surprises outcome for the project. Throughout the project, conference calls, progress meetings and other communications will ensure that the project team is all on the same page and will facilitate early identification and resolution of potential issues that would otherwise delay the project schedule. + + Implement RMC s standard project management tools and QA/QC procedures to provide detailed tracking of budget and schedule and delivery of quality work products. Having prepared many sewer master plans for clients with similar challenges, RMC has a thorough understanding of the issues and proven strategies that can help meet the project objectives. RMC uses several management tools to ensure that high quality deliverables are submitted on time and within budget. We have implemented an integrated business solutions software (Deltek Vision) which enables our project manager to track project costs, schedule and earned value for each project in real time. With this information readily at hand, we can proactively implement any adjustments needed to manage cost and schedule. At the start of each RMC project, our project manager complete a QA/QC Plan within our Deltek system that identifies any technical issues that would require quality control reviews, establishes the expected project deliverables and schedule, and assigns quality control review responsibilities. All work products undergo peer or senior review prior to being submitted to the client. We have also established rigorous quality control procedures specifically for hydraulic modeling and capacity assessment projects. The table below summarizes specific QA/QC procedures for developing the Town s hydraulic model and Master Plan. Work Element Flow Monitoring Data Review Hydraulic Model Construction Model Calibration Improvement Project Development and Cost Estimating RMC QA/QC Procedures Review flow monitoring data to check for data quality and consistency and overall flow balance between meters. Use model data validation tools and pipe profiles to check network connectivity and identify missing or suspect data (e.g., negative pipe slopes, outlet pipe invert elevations higher than inlet invert elevations, areas with apparent datum differences). Request field verification of critical locations such as flow splits. Graph and compare model results versus meter flows to confirm that model is realistically simulating flows in the system. Confer with Town staff to confirm that predicted problem areas agree with field experience. Model calibration is independently checked by designated QA/ QC reviewer. Proposed improvements and cost estimates are reviewed by an experienced design engineer and assessed for potential constructability and other issues through field visits or using aerial photography.

RMC has also played a key role in supporting Berkeley in complying with regulatory compliance orders from the U.S. EPA and State and Regional Boards, including preparing plans for flow monitoring and I/I assessment, inflow identification and elimination, and asset management; required annual reporting; and developing private sewer lateral compliance procedures In 2009, RMC completed the requirements of two critical SSMP elements for the North San Mateo County Sanitation District (which operates the City of Daly City sewer system): the Capacity Evaluation and Assurance Plan, and Condition Assessment and Rehabilitation Plan. Our phased approach to the capacity assurance plan included a thorough review and evaluation of the previous 1993 Master Plan, and development and implementation of a work plan to fill in potential gaps. The work included flow monitoring, development and calibration of an InfoWorks hydraulic model, development of a condition assessment methodology, and development of sewer system improvement CIP. RMC subsequently conducted several other modeling studies for NSMCSD, and in 2015 completed a major update the hydraulic model. Using the updated model, RMC has provided model support for development reviews and various sewer design projects. 680 Collection System Master Plan Update Central Contra Costa Sanitary District RMC prepared an update of the District s Collection System Master Plan in 2010 and is currently completing a new update as part of the District s Comprehensive Wastewater Master Plan. For both projects, existing model loads were determined from the district s HTE customer database, and future development projections were developed on a parcel-basis through review of development plans for each of the 11 planning jurisdictions within the district s service area. The project also included review and updates to design flow and capacity criteria through workshops with district staff. Since 2013, RMC has supported District staff in the development of its new InfoWorks ICM model, including constructing the model network, providing training and developing plans for flow monitoring to support the model development. RMC used flow monitoring data from 70 sites to calibrate the model, and identified capacity deficiencies and needed capacity improvements to handle peak wet weather flows. Collection System Capacity Evaluation/Assurance, Management and Improvement Plan and Collection System Model Update North San Mateo County Sanitation District/ City of Daly City Collection System Master Plan City of Hayward Since Hayward last updated its wastewater collection system master plan, many of the capital improvements recommended by the master plan and sewer impact studies have been completed and other changes have occurred. The city commissioned RMC to prepare an update of the master plan, primarily focusing on hydraulic capacity-related analysis, and recommendation of appropriate short- and long-term capital improvements required to accommodate current and project future wastewater flows. Work included data collection such as flow monitoring and land use inventory, development and calibration of an InfoWorks hydraulic model, establishment of the planning and C.4 Town of Los Altos Hills

19 RMC Water and Environment > > Qualifications engineering criteria, sewer system and pump station facility evaluation and assessment, sewer capacity analysis and improvement projects recommendation. Collection System Master Plan City of Pacifica Pacifica s wastewater collection system includes 96 miles of gravity sewers ranging from 6 to 30 inches in diameter and five pump stations and associated force mains. To assess the capacity of the system, RMC developed and conducted a wet weather flow monitoring program and developed a dynamic hydraulic model of the collection system in InfoWorks, including the major pump stations and force mains. Flow loads to the model were developed at the parcel level using winter water use data available from the water district that serves the city. RMC used the calibrated hydraulic model to develop specific capacity improvement projects, including replacement of undersized sewers to minimize the risk of wet weather SSOs, and a recommended wet weather flow equalization facility. Sanitary Sewer System Hydraulic Model City of Roseville RMC developed a comprehensive hydraulic model of Roseville s sanitary sewer system, after initially assisting the city with an evaluation of potential modeling software. The original model developed in H2OMap Sewer, included all sewers in the city s system, originally used populated based on data from the city s GIS. RMC used detailed land-use data compiled at the parcel level to develop base wastewater loads for the model. The model was calibrated for dry and wet weather conditions based on flow monitoring data collected at 25 locations in the system. We used additional record drawing research, field surveying, and interpolation tools to complete it. RMC coordinated development of the master plan with the efforts of the regional wastewater agency. RMC was subsequently hired to convert the model to InfoWorks ICM and is currently updating and re-calibrating the model using GIS and survey data, water use information, and flow monitoring data. Sewer Master Plan City of San Bruno Due to a high number of sanitary sewer overflows (SSOs), San Bruno was faced with regulatory actions requiring comprehensive capacity and condition assessments of the system. To assess system capacity, RMC conducted flow monitoring, including field verification to confirm critical inventory information, and developed an InfoWorks hydraulic model of the collection system. To facilitate developing a phased sewer rehabilitation plan based on CCTV inspection data collected for the entire collection system, RMC developed a condition assessment and rehabilitation decision process to utilize the CCTV inspection data to identify sewer repairs needed to address major structural defects and critical maintenance issues. The results of the assessments were used to develop a 20-year capital improvement program for needed capacity improvements and near-term and long-term sewer rehabilitation. RMC also provided model support for the design of two major sewer capacity improvement projects that were recommended by the Master Plan. Wastewater Collection System Master Plan City of San Carlos San Carlos is subject to a consent decree with a local nongovernmental organization (NGO) to reduce sanitary sewer overflows and take specific measures related to evaluating the capacity and condition of its system. RMC prepared a hydraulic modeling work plan, as well as a separate capacity assurance report for submittal to and review by the NGO. The capacity assessment included development of an InfoWorks model based on sewer data from multiple sources, calibrated to flow monitoring at 17 locations and verified based on historical SSO locations.

RMC also provided extensive training to city staff on all aspects of model development and use so that they can continue supporting the modeling and master planning effort in the future. Water Pollution Control Plant Sanitary Sewer Capacity Study and Master Plan City of San Leandro San Leandro operates a sanitary sewer collection system that includes over 120 miles of collection pipe in diameters from 4 to 42 and 13 lift stations. RMC was hired to prepare a Sanitary Sewer Capacity Study and Master Plan to address changes in development, planning, and existing conditions of the wastewater collection system since a full capacity study was last completed (in 1993). The city also wished to enhance its programs and decision making processes for maintenance, inspection and rehabilitation of its collection system assets, with the goal of developing programs that optimize the effective use of city resources. Work included flow monitoring, constructing an InfoWorks hydraulic model of the collection system, assessing system capacity and lift station performance, and developing a capacity improvement projects to include in the City s CIP. Sanitary Sewer Model Calibration and Flow Monitoring City of San Mateo, Town of Hillsborough, Crystal Springs County Sanitation District RMC worked with these three San Mateo County cities and agencies to develop InfoWorks hydraulic models of their trunk sewer systems to meet the requirements of a Cease and Desist Order issued by the Regional Water Quality Control Board. The project included flow monitoring during the winter of 2008/09 at over 70 sites to quantify wet weather flows and calibrate the models. For San Mateo, RMC updated the system-wide model that Gisa Ju had previously developed as part of a City-Wide Sewer System Study. RMC compiled and reviewed previous models and existing model-related information, updated and developed the model networks from GIS, developed model loads using water use and land use development information, calibrated the hydraulic models to flow monitoring data, and conducted hydraulic analyses to identify system capacity deficiencies and locations of potential overflows. RMC has continued to provide modeling support to the city for the planning and design of capacity improvement projects. C.6 Town of Los Altos Hills

Gisa managed the preparation of the Phase II Master Plan, which addressed the capacity of trunk and interceptor sewers (10-inch and larger) in the City s entire 2,200-mile system, as well as an update to the areas included in the previous Phase I project to include an expanded sewer network and more focused analysis on priority development areas. The project included development of wastewater loads from water use, census, and land use planning data; wet weather flow monitoring and model calibration using radar rainfall data; assessment of hydraulic capacity using InfoWorks modeling software; and development of recommended capacity improvement projects. A key element of the work was the training of City modeling staff, who were responsible for the modeling for 2 of the 5 major areas of the system. RMC provided extensive guidance documents and both formal and informal model training. After completion of the Master Plan report, RMC continued to provide additional model support, development of GIS processes for updating model loads, and other analyses including estimating depth of sediment accumulation in inverted siphons to assess the potential risk of overflows. Collection System Master Plan for San Mateo (South) Sewershed, Town of Hillsborough Project Manager. Gisa prepared a master plan for the portion of the Town of Hillsborough s sewer system that is tributary to the City of San Mateo. The Master Plan was based on flow monitoring and hydraulic modeling conducted previously in conjunction with the City and the Crystal Springs County Sanitation District, which discharges into Hillsborough s system. The project expanded the model to include additional lines, and also developed a prioritized sewer rehabilitation plan and associated capital cost estimates based on relative infiltration/inflow contribution of the subbasins that comprise this portion of the Hillsborough system. Capacity Evaluation, Management and Improvement Plan, North San Mateo County Sanitation District Project Manager. Gisa managed a study to develop a sewer system rehabilitation and capacity assurance plan for NSCMD, which serves the City of Daly City and adjacent areas.
