<br />City of Redwood City - Sewer System Modeling, Capacity Assessment, and Master Planning <br />Draft Scope of Work <br /> <br />RMC will establish the criteria for model evaluation and selection in conjunction with City <br />engineering staff. The model evaluation criteria will include the model's capability to accurately <br />simulate the hydraulics of the City's system, compatibility with existing and future GIS data, <br />ease of use, purchase price and relative cost of implementation, and availability of technical <br />support and future upgrades. The criteria will also consider specific modeling applications that <br />are needed by the City, such as the ability to easily evaluate the potential impact of <br />redevelopment. Based on the criteria, RMC will identify suitable modeling software applications <br />and evaluate the software with respect to the selected criteria. <br /> <br />Subtask 2.2 - Prepare Technical Memorandum <br />RMC will prepare a TM that discusses the City's current and future modeling needs and <br />compares the modeling software available with respect to the criteria and needs. <br /> <br />Subtask 2.3 - Workshop with City Staff <br />RMC will present and discuss information from the TM at an informal workshop with City staff, <br />and jointly reach a decision on the most appropriate software to use. <br /> <br />Deliverables: <br />. TM on hydraulic model evaluation <br />. Workshop agenda and minutes <br /> <br />Task 3 - Develop Land Use Plannina Information and Parcel Loads <br /> <br />Subtask 3.1 - Review Planning Documents and Meet with Planning Staff <br />RMC will meet with City Planning Department staff to identify and obtain pertinent land use <br />planning maps, data, and documents that provide information required for the Master Plan, and <br />to discuss specific planning issues and potential growth or redevelopment areas in the City. <br />The projected timing of new development will also be discussed with City planning staff to <br />provide input for sewer improvement project phasing. <br /> <br />Subtask 3.2 - Develop Parcel Loads <br />RMC will review existing parcel, customer billing, and water use data to determine if it is feasible <br />to use this data to define existing land uses (e.g., number of dwelling units for residential areas <br />and floor area for commercial/industrial areas) and/or water usage on a parcel-by-parcel basis <br />for purposes of developing wastewater flows for the hydraulic model. The exact methodology to <br />be used to develop model loadings will depend on the format and completeness of the available <br />parcel-based data. If sufficient data is not available to generate loadings on a parcel basis, then <br />land use mapping will be used for this purpose. <br /> <br />Subtask 3.3 - Develop Large User Loads <br />RMC will identify significant point source dischargers such as large industries or major <br />institutional users based on information on water and/or wastewater volume in the billing <br />database and/or industrial monitoring data. Through discussions with the City, RMC shall <br />identify possible changes in flows for large users or potential new large users (industries or <br />institutions). In general, large users will be considered to be those users with average flows <br />greater than about 20,000 gallons per day. Average and peak seasonal and diurnal patterns <br />will be developed for each large user. <br /> <br />Subtask 3.4 - Develop Loading Information for County SSMDs <br />RMC will develop loading information for pertinent County Sewer System Maintenance Districts <br />(SSMDs), including Emerald Lakes, Fair Oak, and the other smaller districts located within the <br /> <br />2 <br />
