RECOMMENDATION(S):

APPROVE and AUTHORIZE the Public Works Director, or designee, to execute a contract with LSA Associates, Inc., effective March 27, 2018 to March 27, 2021 in an amount not to exceed $183,335, for the Marsh Drive Bridge (#28C0442) Replacement over Walnut Creek Channel-Environmental Technical Studies Project, Concord area. County Project No. 0662-6R4119, Federal Aid No. BRLS-5928(128).

FISCAL IMPACT:

This Contract is funded 89% Federal Highway Bridge Replacement Funds and 11% Local Road and Transportation Funds.

BACKGROUND:

Contra Costa County Public Works Department (County) plans to replace the Marsh Drive Bridge over the Walnut Creek Channel (Bridge No. 28C-0442) to meet current California Department of Transportation (Caltrans) design standards as it has reached the end of its design life and will also improve channel hydraulics (the “Project”). The Project is located in the Concord area. The bridge is jointly owned by the City of Concord and Contra Costa County and is approximately 800 feet west of Solano Way.

The Project requires environmental technical studies to support Project impact analysis. Caltrans, acting as the lead agency under the assigned authority of the Federal Highway Administration (FHWA), is providing Project oversight as federal funds are involved. Therefore, LSA Associates, Inc. will provide environmental services to comply with the National Environmental Policy Act (NEPA), in accordance with FHWA and Caltrans requirements, as well as with the California Environmental Quality Act (CEQA) under this Contract.

CONSEQUENCE OF NEGATIVE ACTION:

If the contract is not approved by the Board of Supervisors, it may jeopardize funding and delay construction.
