Report Title: APPROVE a Contract Amendment with Arini Geographics LLC, for Geographic Information Systems (GIS) Support Services.
☒Recommendation of the County Administrator ☐ Recommendation of Board Committee
RECOMMENDATIONS:
APPROVE and AUTHORIZE the Chief Engineer, Contra Costa County Flood Control and Water Conservation District, or designee, to execute, on behalf of the Contra Costa Clean Water Program, a contract amendment with Arini Geographics LLC, effective June 10, 2025, to increase the payment limit by $550,000, to a new payment limit of $900,000 and to extend the contract termination date from June 30, 2026 to June 30, 2028 for Geographic Information Systems (GIS) Support Services necessary to maintain compliance with the Municipal Regional Stormwater Permit (MRP), Countywide.
FISCAL IMPACT:
All costs associated with this contract will not exceed $900,000 and will be funded by stormwater utility fee assessments collected by the Cities/Towns and County, proportional to their respective populations. (100% Stormwater Utility Assessment Funds)
BACKGROUND:
The Contra Costa Clean Water Program (the "CCCWP") consists of Contra Costa County, its 19 incorporated cities/towns, and the Contra Costa County Flood Control and Water Conservation District (referred to collectively as "Permittees"). The CCCWP was established in 1991 through a Program Agreement in response to the 1987 amendments to the federal Clean Water Act ("CWA"), which established a framework for regulating municipal stormwater discharges under the National Pollutant Discharge Elimination System ("NPDES") Permit Program. The U.S. Environmental Protection Agency published final rules implementing the 1987 CWA amendments in November 1990. The rules mandate that Permittees obtain and implement stormwater permits designed to reduce and eliminate the discharge of pollutants into and from Municipal Separate Storm Sewer Systems they own and operate. Through the CCCWP, Permittees conduct many of the mandated activities collectively (referred to as "Group Activities"), such as water quality monitoring, special studies, public education and outreach. The roles and responsibilities of the CCCWP and Permittees are outlined in the Program Agreement, which was last updated and adopted by all Permittees in June 2010.
The CCCWP Permittees request retain Arini Geographies LLC to assist CCCWP with GIS administration, system design and modification, technical assistance and training quality assurance and control to meet compliance with the Municipal Regional Stormwater Permit (MRP).
CONSEQUENCE OF NEGATIVE ACTION:
Without the approval of the Board of Supervisors, the CCCWP, 19 Cities and Towns, Contra Costa County, and the Flood Control District will be unable to meet the NPDES Permit requirements set forth by the San Francisco Bay Region Municipal Regional Stormwater. NPDES Permit No. CAS612008, Order R2-2015-0049
