RECOMMENDATION(S):

APPROVE and AUTHORIZE the Chief Engineer, Contra Costa County Flood Control and Water Conservation District (Flood Control District), or designee, to execute a contract with Kjeldsen, Sinnock & Neudeck, Inc. (KSN) in an amount not to exceed $2,393,020 to provide professional construction management and biological monitoring services in support of the Lower Walnut Creek Restoration Project for the period of November 12, 2020 through December 31, 2024, Martinez area.

FISCAL IMPACT:

This contract is funded by a combination of local funds from the Flood Control District Zone 3B (53%) and local and state grants (33% San Francisco Bay Restoration Authority Measure AA, 14% California Department of Fish and Wildlife Proposition 1).

BACKGROUND:

The Lower Walnut Creek Restoration Project (Project) will improve habitat for a number of rare and endangered species while providing sustainable flood risk reduction near the mouth of Walnut Creek on the southern shore of Suisun Bay. The construction contract for the Project was awarded by the Board on March 23, 2021.

BACKGROUND: (CONT'D)

Implementing this wetland restoration project requires specialized professional services that are not available with in-house staff. To address this need, the Flood Control District issued a Request for Qualifications and a subsequent Request for Proposals, developed a shortlist of qualified firms, interviewed the top three, and ultimately selected KSN as the most qualified firm to fill this need.

The tasks to be performed by KSN generally include managing the overall construction contract on behalf of the Flood Control District, providing inspection and quality assurance field and laboratory testing of the construction contractor’s work, surveying for rare and endangered species, delineating sensitive habitat areas, providing biological monitoring of the construction contractor’s work, ensuring contractor’s compliance with regulatory permit requirements and with California Environmental Quality Act (CEQA) mitigation measures, and providing post-construction monitoring and reporting to ensure the Project performs as designed.

The duration of this contract generally matches the duration of the Project’s recently awarded construction contract, which includes the construction season, plus three years of vegetation monitoring and maintenance.

CONSEQUENCE OF NEGATIVE ACTION:

Without the approval of this contract by the Board of Supervisors, the Flood Control District will be unable to perform the biological monitoring required by the Project’s regulatory permits and CEQA mitigation measures, and the Flood Control District will not be able to provide needed professional construction management services for the Project.
