Report Title: On-call Contract with Blankinship, a Bowman Company, Countywide.
☒Recommendation of the County Administrator ☐ Recommendation of Board Committee
RECOMMENDATIONS:
APPROVE and AUTHORIZE the Public Works Director, or designee, to execute a contract with Blankinship, a Bowman Company, a California Corporation, in an amount not to exceed $715,000 to provide on-call professional stormwater quality services for the Aquatic Pesticides and the San Francisco Bay Region Municipal Regional Stormwater National Pollutant Discharge Elimination System (NPDES) Permit (MRP) requirements for the period of April 1, 2025 through March 31, 2028, Countywide.
FISCAL IMPACT:
This project, including the contract, will be funded 80% by the agencies under the Aquatic Pesticides NPDES Permit Joint Exercise of Powers Agreement (JEPA), including Contra Costa County Flood Control and Water Conservation District (FC District), and 20% by the Stormwater Utility Area Assessment Funds. Project No. 7517-6W7241
BACKGROUND:
The Contra Costa County Watershed Program (CWP) assists with the coordination of the JEPA for the Aquatic Pesticide General NPDES Permit (Water Quality Order No. 2013-0002-DWQ, General Permit No. CAG990005) and is responsible for implementing the MRP under the NPDES No. CAS612008 on behalf of Contra Costa County and the FC District.
The FC District is one agency under the JEPA for the Aquatic Pesticide Permit. The other JEPA members include the City of Antioch, Alameda County Public Works, and Zone 7 Water Agency. The City of Concord was active when the group was formed in the early 2000s, but has been inactive with the JEPA and NPDES for over a decade. The JEPA was formed to develop and implement a monitoring plan for each discharger’s permit under the Aquatic Pesticides permit.
The Aquatic Pesticides permit requires agencies to minimize the impacts of and monitor creeks for aquatic pesticides, if used. The MRP requires municipalities to reduce pollutants in the stormwater flowing through their drainage systems and subsequently reducing negative impacts to creeks, the Bay, and the Delta from trash, abandoned waste, and other pollutants of concern found in urban runoff.
The CWP requires on-call professional service contracts for the provision of expertise in a variety of technical fields in support of meeting requirements of the NPDES Permits and additional County initiatives.
CONSEQUENCE OF NEGATIVE ACTION:
Without the approval of this contract by the Board of Supervisors, Contra Costa County will be unable to meet its requirements under the Aquatic Pesticides permit CAG990005 and the MRP No. CAS612008.
