Ventura County is the northwestern end of our service area — coastal cities like Ventura and Oxnard, the Oxnard Plain’s working agricultural communities, and the Conejo Valley suburbs of Thousand Oaks, Simi Valley, Camarillo, and Moorpark. The scopes here are the same ones we build everywhere: underground utilities, sewer and water mains, storm drain, trenching, and street restoration, self-performed by our own crews. We serve Ventura, Oxnard, Thousand Oaks, Simi Valley, Camarillo, and Moorpark, bidding public and private work.
Civil & Underground Services in Ventura County
One Class A contractor for the whole underground scope — self-performed by our own crews, from open cut to final restoration.
- Underground Utilities — Complete wet and dry utility installation — pipe, vaults, and conduit — from trench to tie-in.
- Sewer & Water Mains — New mains, replacements, and tie-ins built to agency spec and pressure-tested before backfill.
- Storm Drain — Storm drain pipe, structures, and catch basins that move water where it belongs.
- Trenching & Excavation — Safe, shored, traffic-controlled excavation by our own operators and our own iron.
