Outside Zone Agreement to Connect Maddux Ranch Regional Park to the Airport Larkfield-Wikiup Sanitation Zone

The Sonoma County Water Agency has entered into an Outside Zone Agreement with Sonoma County Regional Parks to provide sanitation services to Maddux Ranch Regional Park. Located at 4555 Lavell Road in unincorporated Sonoma County, the project involves the authorization of a connection to the Airport-Larkfield-Wikiup Sanitation Zone. This infrastructure upgrade will support park facilities by enabling the installation of a public restroom to replace the existing use of portable toilets on the 10-acre parcel. The project is classified under NAICS code 237110 and is identified as exempt under Section 15301(b) for Existing Facilities, as the annexation into the existing sewer system is expected to result in negligible or no expansion of public use. Connie Barton serves as the primary point of contact for the agency. While the project is listed as a forecast with a posted date of August 4, 2026, specific contract values and performance periods are not provided in the current documentation.
