<br />Consulting Services Agreement between City of San Leandro and 6 November 2023 <br />Schaaf and Wheeler for Trash Load Reduction Planning Exhibit A – Page 1 of 5 <br />The following is a summary of the ‘Scope of Services’ to be included in the Contract Services <br />Agreement with Schaaf and Wheeler for the Storm Water Trash Capture Devices, Project No. <br />2017.0540 <br /> <br /> <br />SCOPE OF SERVICES <br /> <br />This contract provides for the design and preparation of construction bid documents for the <br />installation of trash capture devices (TCD) recommended in the Full Trash Capture Feasibility <br />Study dated June 2023. Six TCD sites are identified in this study and it is anticipated that all <br />sites will be designed and bid at the same time. The requirements and conditions vary for <br />each of the proposed TCD locations: two are in Caltrans right of way (ROW), four are on <br />Alameda County Flood Control District (ACFCD) pipes or ROW, and two are on the East Bay <br />Regional Park District (EBRPD) property. One is located near a pump station, and three are <br />likely to be tidally influenced. At three locations, there may be the opportunity to install an <br />outfall device. <br /> <br />Phase 1 - Preliminary Design <br />Task 1.1 Project Management and Meetings <br />This task includes project management and meetings with City staff as needed to <br />accomplish the preliminary design. Consultant to allow for a minimum of two (2) on- <br />site progress and coordination meetings. <br /> <br />Task 1.2 Data Collection and Research <br />This task includes items related to collecting the necessary background data needed to <br />start design work on the project, including the following: <br />• Onsite field assessments and reviews of existing stormwater drainage and utility <br />conditions at each proposed location. Review available construction drawings and <br />other available information. <br />• Investigation of existing site conditions, including existing utilities research and <br />geotechnical desktop analysis and pre-field activities. Includes one day of field visits <br />by the project engineer, geotechnical engineer, and the environmental permitting <br />consultant. <br />• Recommend brand and model for each TCD location that meets the 1-year event <br />down to 5 mm particles permit requirement. <br /> <br />Task 1.3 Hydraulic Evaluation and Analysis <br />This task will review and analyze hydraulic impacts of the proposed trash capture <br />devices on existing hydrology, including the following: <br />• Determine 1-year, 1-hour and peak (15- and 100-year) flow rates using hydraulic <br />models. Either existing models will be obtained from the ACFCD and modified to <br />determine the 1-year flow rate, or Consultant will develop hydrologic models in HEC-
