RECOMMENDATION(S):

APPROVE and AUTHORIZE the Public Works Director, or designee, to execute the Cooperative Implementation Agreement, including County indemnification, with the California Department of Transportation (Caltrans) for Caltrans to reimburse the County in an amount not to exceed $3,945,000 for the County's design and construction of three large full trash capture devices in unincorporated San Pablo (Tara Hills) for the period of June 2, 2020 to May 1, 2023.

FISCAL IMPACT:

The Project is being funded by Caltrans, per the Cooperative Implementation Agreement (CIA). Some minimal set-up costs will be paid for by the Stormwater Utility Assessments as part of Contra Costa County’s (County) Trash Reduction Measures.

BACKGROUND:

The County is a permittee under the San Francisco Bay Region Municipal Regional Stormwater National Pollutant Discharge Elimination System Permit (MRP). One of the current MRP requirements is to reduce trash discharging from the County municipal separate storm sewer system (MS4) by 100% by 2022. As part of this effort, the County is looking for opportunities to install full trash capture systems to prevent trash from flowing from MS4s to creeks and the Bay.

Caltrans is also required to reduce trash from its highways, which travel through communities and have stormwater drainage systems that tie into MS4s. Caltrans is looking for opportunities to partner with municipalities to implement trash control measures. Unincorporated County has an opportunity to collaborate with Caltrans under a CIA. Under a CIA, Caltrans would provide the funds to pay for the design and installation of large full trash capture systems in the County storm drain system in Tara Hills, unincorporated San Pablo. The County would coordinate the planning, design, and installation and would maintain these systems within the County road right of way. Both Caltrans and the County would receive credits from the San Francisco Bay Regional Water Quality Control Board for the reduction of trash and possibly from the removal of PCBs (polychlorinated biphenyls) and mercury, bound to sediment, from the MS4.

The County is obligated to indemnify Caltrans for third party claims arising out of the County's acts or omissions in performing the agreement.

CONSEQUENCE OF NEGATIVE ACTION:

If this action isn’t approved, the County will not be able to install large full trash capture devices in Tara Hills.
