RECOMMENDATION(S):

APPROVE and AUTHORIZE the Public Works Director, or designee, to execute a contract amendment with AECOM Technical Services, Inc., effective July 20, 2019, to increase the payment limit from $260,000 to a new payment limit of $280,000 and extend the term from July 20, 2019 to July 20, 2020, to complete environmental compliance services for the Marsh Creek Road Bridges (#28C-0143 & #28C-0145) Replacement-Environmental Technical Studies Project, Antioch and Brentwood areas. (District III) County Project No. 0662-6R4083, Federal Project ID#BRLS-5928 (125)

FISCAL IMPACT:

70% Federal Highway Bridge Replacement Fund and 30% Local Road Fund

BACKGROUND:

Contra Costa County (County) Public Works Department plans to replace two existing bridges (#28C-0143 and #28C-0145) on Marsh Creek Road to meet current California Department of Transportation (Caltrans) design standards (the “Project”). The Project is located on Marsh Creek Road, in the unincorporated Antioch/Brentwood area. Bridge #28C-0143 is approximately 1.6 miles west of Deer Valley Road; and Bridge #28C-0145 is approximately 3.1 miles east of Deer Valley Road and approximately 0.2 mile west of Camino Diablo. The Project requires environmental technical studies for environmental compliance.

All environmental studies must meet federal, state, and local environmental regulations, including but not limited to Federal Highway Administration (FHWA) and Caltrans requirements, National Environmental Policy Act (NEPA), California Environmental Quality Act (CEQA), National Historic Preservation Act (NHPA), the Clean Water Act, the Porter-Cologne Water Quality Act, federal and state Endangered Species Acts, National Marine Fisheries Service (NMFS) requirements, U.S. Fish and Wildlife Service (USFWS), California Department of Fish and Wildlife (DFW), East Contra Costa County Habitat Conservation Plan/Natural Community Conservation Plan (HCP/NCCP), as well as with other responsible agency protocols, guidelines, and regulations. The Project is also within the HCP/NCCP inventory area, which requires specific environmental compliance.

Due to the County's continuing need for environmental technical services for the Project, the Contract payment term needs to be extended and the Contract Payment limit needs to be increased in order to meet federal, state, and local environmental regulations for environmental compliance.

All other terms and conditions of the original Contract between the County and the Contractor, not modified by any previous amendments and this amendment, shall remain in full force and effect.

CONSEQUENCE OF NEGATIVE ACTION:

If the amendment is not approved, the remaining work will not be completed to obtain necessary environmental clearances which may jeopardize funding and cause delays with construction.
