Working in Colusa County

BC Brown General Engineering has served Colusa County since 1999. Colusa County is rice country along the Sacramento River, from the county seat at Colusa to the I-5 towns of Williams and Maxwell and the Coast Range foothills. We bring the same crews, equipment, and standards to every job here, from a single driveway to a full site build.

Colusa County covers heavy valley clay rice ground. We work all of it, matching the approach to the ground: engineered bases on valley clay, benched cuts in the foothills, and frost-ready work up high.

Colusa County is south down the valley. We pull permits through Colusa County Environmental Health when the job calls for it, from septic and grading to encroachment, and handle the inspections so the work closes out clean.
