RECOMMENDATION(S):

Acting as the governing body of the Contra Costa County Flood Control and Water Conservation District (FC District), APPROVE and AUTHORIZE the Chief Engineer, or designee, to execute a Consulting Services Agreement (Contract) Amendment with Balance Hydrologics, Inc., to increase the payment limit by $650,000 to a new payment limit of $1,020,000 and to extend the term through May 13, 2024, for on-call professional engineering services relating to hydrology/hydraulic studies and modeling, Countywide.

FISCAL IMPACT:

This amendment, including the Contract, will be funded by 43% FC District Funds and 57% Flood Control Zone 1 Funds. (Project No.: Various)

BACKGROUND:

The FC District provides regional flood protection, technical information, hydrology data and education to cities and residents, and environmental stewardship for over 70 miles of streams and several detention basins, as part of the County’s flood protection system. The FC District anticipates the need to deliver important infrastructure in the Marsh Creek watershed to keep ahead of development. As such, the FC District is increasing the payment limit and extending the term for a single additional year of its agreement for on-call support for hydrology/hydraulic studies and modeling to plan and design the Lower Sand Creek Basin. Additionally, the City of Brentwood has begun work on the adjacent Sand Creek Sports Park, which is integrated with the FC District’s Lower Sand Creek Basin. This amendment is necessary to ensure that timely services for planning and design of the Lower Sand Creek Basin are delivered in tandem with the City of Brentwood’s sports park project.

CONSEQUENCE OF NEGATIVE ACTION:

Without the approval of the Board of Supervisors, the FC District will not be able to obtain timely on-call support for hydrology/hydraulic studies and modeling.
