Camp 4 Stormwater Pump Repair Project
City/County:

Unincorporated, Sonoma County
Comment Period:

10/14/2025 - 11/3/2025
Project Description:

Sonoma Land Trust will construct the Camp 4 Stormwater Pump Station Replacement Project in Fall of 2025 to replace an existing, collapsed stormwater pump station and flap gate. The pump station will convey stormwater from an agricultural ditch to Hudeman Slough to prevent flooding and to manage mosquito habitat. Without proper stormwater pump operation during the rainy season, the property will flood and create approximately 800 acres of mosquito vector habitat.
