RECOMMENDATION(S):

APPROVE and AUTHORIZE the Interim Public Works Director, or designee, to execute a contract amendment with LSA, Associates, Inc., for additional specialized assessments in preparation for construction and to comply with environmental regulations for the Marsh Creek Road Bridge (#28C-0141) Replacement-Environmental Technical Studies Project, with no change to the payment limit or term, Clayton area. Project No. 0662-6R4079/BRLO-5928(107).

FISCAL IMPACT:

FISCAL IMPACT: (CONT'D)

89% Federal Highway Bridge Program Funds and 11% Local Road Funds fund the contract. The amendment will have no fiscal impact.

BACKGROUND:

Contra Costa County Public Works Department intends to replace the existing Marsh Creek Road Bridge (#28C-0141) 2 miles east of Morgan Territory Road, located in the Clayton area. The Marsh Creek Road Bridge Replacement Project (Project) consists of widening and realigning the sections of Marsh Creek Road leading up to the bridge and constructing a new bridge.

The Project is federally funded, which requires special environmental analysis, assessments, technical studies, and associated reports to ensure environmental compliance in accordance with the standards and protocols pursuant to the following environmental laws and regulations: Federal Highway Administration (FHWA), California Department of Transportation Local Assistance (Caltrans), United States Army Corps of Engineers (USACE), National Environmental Policy Act (NEPA), the California Environmental Quality Act (CEQA), the Clean Water Act, the Porter-Cologne Water Quality Act, and the State and Federal Endangered Species Acts. All studies must meet Caltrans requirements, as well as state and federal requirements. The Project is located within the East Contra Costa County Habitat Conservation Plan/Natural Community Conservation Plan (HCP/NCCP) area, which also requires specialized assessments and surveys pursuant to the HCP/NCCP Plan.

Due to the County’s need for additional environmental services in preparation for construction to comply with environmental regulations, portions of the Contract Service Plan need to be amended to include additional scope of services.

CONSEQUENCE OF NEGATIVE ACTION:

Without Board approval, completion of the Project could be delayed due to non-compliance of environmental regulations.
