THE CITY OF 1 6 CITY COUNCIL AGENDA REPORT pLEASANTON August 21, 2018 Operations Services TITLE: ADOPT RESOLUTION TO APPROVE AN AGREEMENT WITH THE CALIFORNIA DEPARTMENT OF TRANSPORTATION TO RECEIVE $300,000 FOR THE DESIGN AND CONSTRUCTION OF A TRASH CAPTURE PROJECT TO TREAT RUNOFF FROM A 92-ACRE DRAINAGE AREA ADJACENT TO INTERSTATE 680 AND BERNAL AVENUE SUMMARY The California Department of Transportation (Caltrans) is constructing a ramp metering project at Interstate 680 and Bernal Avenue and proposing to discharge stormwater runoff from 1 .75 acres of the highway to the City's storm drain system. City staff has negotiated a Cooperative Agreement (the "Agreement") with Caltrans whereby Caltrans will contribute $300,000 for the construction of a full trash capture device, within a City easement at Koll Center, to treat runoff from 92 acres of nearby drainage area. In return, the City will implement the Project and maintain the trash capture device in perpetuity. The chosen trash capture device is on the State's list of systems certified to help the City meet full trash capture requirements contained in Provision C.10 of the San Francisco Bay Regional Water Quality Control Board's (RWQCB's) Municipal Regional Permit (MRP). Caltrans can also earn compliance credit under their own stormwater permit for their contribution of funds to this effort. RECOMMENDATION Adopt resolution approving the Agreement with Caltrans. FINANCIAL STATEMENT Staff expects $300,000 to be sufficient for the design and construction of the Project. Any additional costs, including those for the Project's on-going post-construction maintenance, are included in the annual Operations Services Department budget. No additional appropriations are required.
