REV: 01-27-23 JB <br />EXHIBIT “A” <br />SCOPE OF SERVICES AND FEE <br />Consultant shall provide hydraulic modeling support related to evaluating the impact of <br />the proposed developments at 1 and 10 Twin Dolphin Drive on the City’s Redwood <br />Shores wastewater collection system. The work will be based on the hydraulic model <br />developed and used for the City’s draft Sanitary Sewer Master Plan prepared in 2021. <br /> <br />The work items included in this project are described below. <br /> <br />Consultant will create new model scenarios incorporating the proposed Twin Dolphin <br />Drive development projects. Three (3) scenarios will be created: for each development <br />individually and a combined development scenario. The estimated flows from the <br />proposed developments will be added to the model based on the proposed development <br />types and sizes as provided by the City and the City’s design unit flow factors. <br />Consultant will run the model for dry weather and design storm wet weather scenarios. <br />Diurnal wastewater flow profiles, infiltration/inflow rates, pump station operating <br />parameters, and design storm rainfall will be based on those used for the draft Sewer <br />Master Plan. Based on the model results, Consultant will assess the capacity impact of <br />the projects on downstream sewers and pump stations PS01 and PS02 (based on their <br />firm capacity as reported in the draft Sewer Master Plan report). <br />Consultant will summarize the model results in a brief Technical Memorandum (TM) for <br />review by the City. The TM will document the model updates and assumptions made for <br />the evaluation. Comments received from the City will be incorporated into a final TM. <br />Consultant will provide overall contract management of the project, including monitoring <br />of project budget and schedule, preparation of invoices, and communication with the City <br />by telephone and e-mail regarding project status and issues. <br /> <br />Deliverables: <br />Draft and final summary TMs <br />Monthly invoices and progress reports <br /> Fees: <br />Consultant shall complete the services based the hourly rate schedule provided below. <br />Schedule: <br />Draft TM will be submitted within 21 working days after receipt of Notice to Proceed <br />from the City and confirmation of the development quantities for the two development <br />projects. <br />ATTY/AGR.2023.015/Woodard & Curran (Twin Dolphin Serwer Impact) (Page 11 of 12)
