RECOMMENDATION(S):

APPROVE and AUTHORIZE the Public Works Director, or designee, to execute a contract amendment with Cleanstreet, LLC, to increase the payment limit by $271,000 to a new payment limit of $1,521,000 to provide routine street sweeping services for curbed streets in unincorporated Contra Costa County, and to extend the term from December 31, 2021 to December 31, 2022, Countywide.

FISCAL IMPACT:

The project is funded by 100% Local Road Funds.

BACKGROUND:

The County Watershed Program is responsible for ensuring the County’s compliance with the current and reissued National Pollutant Discharge Elimination System (NPDES) stormwater permit issued by the San Francisco Bay Region of the California Regional Water Quality Control Board (RWQCB). Permit provisions are met through various pollution prevention programs, including municipal maintenance and reduction of pollutants of concern, in order to reduce water-quality impacts from urban runoff.

BACKGROUND: (CONT'D)

Routine street sweeping helps satisfy the mandated reduction of pollutants to the County’s storm drain system. Street sweeping removes sediment, debris, and other contaminants that might normally enter the storm drain system and flow untreated to creeks and other natural waterways. Adoption of this contract amendment allows monthly street sweeping of curbed streets in unincorporated areas of the County to continue in the following four service areas and unincorporated communities:

· West County (El Sobrante, East Richmond Heights, North Richmond, SW Kensington, Rodeo, Crockett, Rollingwood, Montalvin/Montara Bay, and Tara Hills)
· Central County (Pacheco, Clyde, Vine Hill, North Concord, Pleasant Hill, and Saranap)
· East County (Discovery Bay)
· South County (Alamo and Camino Tassajara)

The Public Works Department, Watershed Program administers this street sweeping contract for clean water compliance. The County Watershed Program is not responsible for nonroutine street sweeping related to road improvements and maintenance (chip seal cleanup) and/or construction projects.

CONSEQUENCE OF NEGATIVE ACTION:

Without the approval of the Board of Supervisors, no routine street sweeping service will be provided to residents of unincorporated Contra Costa County. The County will be out of compliance with its Municipal Stormwater NPDES Permit with the RWQCB, which could result in enforcement action and fines. Neighborhoods will suffer from the unsightly accumulation of trash collecting within gutters. They may experience localized flooding from excess leaves collecting within drainage inlets during the rainy season, and they may encounter safety issues from the buildup of road-associated debris, i.e., rocks and aggregate.
