Lookout Slough Restoration Project

The California Department of Water Resources is conducting geotechnical exploration activities for the Lookout Slough Restoration Project, specifically focusing on the Shag Slough Bridge Removal Soil Sampling in Solano County. The scope of work involves collecting one discrete soil sample from four predetermined boring locations, S1 through S4, situated on either side of the bridge scheduled for demolition. Using a 2.5-inch hand auger, borings S1 and S3 will be advanced to 10 feet below ground surface, while borings S2 and S4 will be advanced to 2 feet. Samples are to be collected at the terminus of each boring or at the point of drilling refusal and transferred directly into laboratory supplied containers. This project is classified as a forecast under NAICS code 541360 and is managed by the Division of Integrated Science and Engineering's Tidal Habitat Restoration Section. A Notice of Exemption was issued on July 16, 2026, claiming an exemption under Class 6, Section 15306 for information collection, as no significant environmental impact is anticipated. Primary points of contact for the project include Senior Environmental Scientist Emily Read and Program Manager Dan Riordan. The project location is specifically identified by coordinates 38.306586, -121.693500.
