RECOMMENDATION(S):

APPROVE and AUTHORIZE the Public Works Director, or designee, to execute a contract amendment with CLEANSTREET, LLC, effective March 31, 2023, to increase the payment limit by $530,000 to a new payment limit of $2,130,000 and extend the term through December 31, 2023, for street sweeping services, Countywide.

FISCAL IMPACT:

This project is funded by 100% Local Road Funds.

BACKGROUND:

The County Watershed Program administers the National Pollutant Discharge Elimination System (NPDES) Municipal Regional Stormwater Permit (MRP) issued by the San Francisco Bay Region of the California Regional Water Quality Control Board for unincorporated Contra Costa County. The MRP provisions are met through various pollution prevention programs, including municipal maintenance best management practices and the reduction of pollutants of concern, in order to reduce pollutants to rainwater that flows to county creeks and streams.  




BACKGROUND: (CONT'D)
  
Routine street sweeping helps satisfy the mandated reduction of pollutants to the County’s storm drain system and helps keep the roads clean and safe. Street sweeping removes sediment, litter, 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, and some semimonthly, 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 the MRP, which could result in enforcement action and fines. Neighborhoods will suffer from accumulation of debris and litter 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.
