III. Reasons for Recommendations and Backl1round:
Adoption of this contract will result in semi-monthly street sweeping of curbed streets in the unincorporated
areas of Pacheco/Martinez,Clyde,industrial north central county(Concord area),Pleasant Hill BART,and
Discovery Bay. The City of Oakley is now incorporated and will handle their own street sweeping services.
The County's Clean Water Program will administer this contract. The contractor, Enviro Street Sweeping,
presented the lowest overall bid. Routine street sweeping satisfies the goal of the County's Clean Water
Program,to reduce,eliminate,and prevent stormwater pollution and is mandated by the California Regional
Water Quality Control Boards through their joint Municipal Stormwater NPDES Permit with the County and
cities of Contra Costa. This activity removes sediment,debris,and other contaminants that might normally
enter the storm drain system and flow untreated to creeks and other natural waterways.
The County's Clean Water Program is not responsible for non-routine street sweeping related to road
improvements and maintenance (chip seal cleanup) and/or construction projects.
Until 1996, departmental policy had been to employ street sweeping for public safety concerns, (e.g.,
removing gravel from roads with heavy bike use,debris related to road improvement projects or cleaning up
after pavement maintenance activities such as chip seal),not routine street sweeping. The exception to this
policy had been Discovery Bay, Pleasant Hill BART and the Alamo area (Danville Blvd., Stone Valley
Road) where the costs of routine street sweeping were covered by a special assessment or district. Other
exceptions include locations receiving the service from another agency, such as Delta Diablo Sanitary
District in Bay Point.The County's Clean Water Street Sweeping Program is not responsible for non-routine
cleaning services such as those referenced above (debris related to road construction or pavement
maintenance activities).
IV. Consequences of Negative Action:
No routine street sweeping will be provided to Pacheco/Martinez, Clyde, industrial north central county
(Concord area), Pleasant Hill BART, and Discovery Bay. The County will not be in compliance with its
Joint Municipal Stormwater Permits with the San Francisco Regional Water Quality Control Board and/or
the Central Valley Regional Water Quality Control Board.
