RECOMMENDATION(S):

APPROVE and AUTHORIZE the Interim Public Works Director, or designee, to execute a contract amendment with Contract Sweeping Services, Inc., to extend the term from October 31, 2017, through April 30, 2018, to provide street sweeping services, with no change to the payment limit, Countywide.

FISCAL IMPACT:

All costs associated with this contract will not exceed $600,000, and will be funded by the Stormwater Utility Assessment revenue from the unincorporated areas (Fund No. 251700) designated to the County Watershed Program.

BACKGROUND:

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 extension 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 non-routine 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 during these three months. 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.
