The County Watershed Program is responsible for ensuring the County’s compliance with two state mandated municipal stormwater discharge permits under the National Pollutant Discharge Elimination System (NPDES): the Municipal Regional Permit (MRP) No. CAS612008 and the East Contra Costa County Municipal NPDES Permit No. CAS083313. The permits’ 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.
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 will allow 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 will administer 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.
The contractor, Universal Building Services and Supply Co. (UBS) competed against three other companies in an electronic closed bid process (BidSync) and presented the lowest overall bid. UBS is currently successfully providing routine street sweeping services to the County.
No routine street sweeping service will be provided to residents of unincorporated Contra Costa County. The County will not be in compliance with its Municipal Stormwater NPDES Permits with the San Francisco Bay and Central Valley Regional Water Quality Control Board(s), which could result in enforcement action and fines of up to $15,000 per day. 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.
