From:Jason Simpson, City Manager
Prepared by:Shannon Buckley, Assistant City Manager
Date:May 27, 2025
Subject: Amendment No. 2 to the Professional Services Agreement Between the City and Engineering Resources of Southern California Inc.(ERSC) for the Civil Engineering Services of the New City Hall Project (CIP Project Z20006).
Recommendation
Approve and authorize the City Manager to execute Amendment No. 2 with Engineering Resources of Southern California, Inc. (ERSC) for a total not to exceed amount of $144,642.00 in such final form as approved by the City Attorney.
Background
Staff has engaged the services of Engineering Resources of Southern California Inc. (ERSC) to provide civil engineering design services with valued engineering concepts. These services are needed to create an engineered building pad for the new corporate facility. ERSC and the City’s architect, STK Architectural, will work together with the help of Dennis Janda Surveying to establish an engineered build site complete with utility connections.
Discussion
These services are in addition to the original civil engineering services for the site development of the project and will include the needed civil engineering construction documentation to affect the utility connection and modified original site development plans. Key tasks are included in the following:
Grading & Street Plans - Modify the current plan set to account for the relocation of the existing access to the alley to the easterly edge of the city hall property.
ERSC Amendment No. 2 New City Hall Project (CIP Project Z20006).
- Modification of the street design along the south side of Graham Street includes curb and gutter, sidewalk, and a new commercial driveway approach including an accessible path of travel. Confirm the design of the proposed grind and overlay on Graham Street. - Redesign grading in the alley to provide access to the existing traveled way in the alley including grading and paving south of Graham Avenue and revised grading along the alley at the rear of the new building.
- Modify drainage design at the northeast corner of the proposed building and along the alley reconstruction to accommodate the modular wetland and ensure adequate treatment of site runoff.
Fire Line Connection – Design related to the relocation of the fire department connection to Graham Street east of the proposed driveway. Remove the fire department connection from its current location on Main Street to the new location Graham Avenue. Provide design of the proposed waterline connection, piping, DCDA, post indicator valve, fire department connection, various check valves, and a new fire hydrant. Route piping from the fire department connection to the point of connection at the building. Prepare fire flow calculations for multiple scenarios based on the new design and previously acquired fire flow data from EVMWD.
Potholing – Coordinate potholing activities with USI, review and interpret pothole reports, and add tabulated pothole data the plans for EVMWD.
Sewer Video – Provide coordination, video review, and data interpretation for video footage of the existing sewers in Main Street and Graham Avenue necessary to locate three sewer laterals serving the three buildings that previously occupied the city hall site. Add sewer lateral locations to the EVMWD plans and coordinate abandonment thereof with District staff.
Deliverables
Modified Grading, Drainage and Street Plans.
Modified Water and Sewer Plans with Fire Water Flow Calculations (EVMWD).
Additions to EVWMD plans to show tabulated pothole data.
Sewer video and addition of sewer laterals to EVMWD plans Fiscal Impact
