CalSIP, California Stream Gage Improvement Program

The California Stream Gage Improvement Program, managed by the City of Petaluma Water Resources and Utilities Department, involves the installation of six stream gage monitoring sites across the Petaluma River, Adobe Creek, Washington Creek, and Lichau Creek. The project aims to fill critical data gaps in the state's surface water monitoring network by deploying sensors and telemetry equipment that provide real-time hydrologic data to the public and the California Data Exchange Center. All six sites must be installed by October 2026, with the work being performed by City Staff, Sonoma RCD, and a Field Engineer from Xylem Water Solutions. The project is categorized as a special notice under NAICS code 541370 and is administratively led by Oriana Hart, the Water Resources and Conservation Manager. Because the project involves minimal physical disturbance for the purpose of information collection, it is categorically exempt under CEQA Guidelines Section 15306. Equipment may remain in place beyond the initial one-year reporting period to continue the collection of internal surface water data.
