Hanford

What Hanford does

Hanford ARC (doing business as "Hanford Builds") is a licensed general engineering and landscape contractor headquartered at 775 Baywood Drive, Petaluma, California, founded in 1984 by Doug Hanford. The company specializes in ecological restoration and heavy civil construction within environmentally and culturally sensitive resource areas, with more than 100 civil projects completed across Northern California. Its work spans wetland mitigation, tidal habitat restoration, fish passage improvement, dam removal, meadow restoration, shoreline stabilization, and erosion control. The firm operates four service divisions: Heavy Civil Construction (large-scale technical projects in ecologically sensitive areas), Construction Services (work for private landowners, utilities, and government agencies), Land Management (vegetation management, invasive species removal, and ongoing stewardship), and Estimating (project cost estimation). Notable projects include the 230-acre Ackerson Meadow Restoration in Yosemite National Park, the Lookout Slough tidal habitat project in the Sacramento-San Joaquin Delta (608 acres of mesohaline tidal habitat for Delta smelt), the Sunol Valley Fish Passage Project on Alameda Creek, the Dry Creek Habitat Enhancement for Sonoma County Water Agency, and the Dunphy Park Phase 2 shoreline stabilization in Sausalito.

Hanford operates on a project-based revenue model, acquiring work through competitive bidding administered via the SmartBidNet Plan Room system, where subcontractors and suppliers must pre-register. Revenue is generated from heavy civil construction services, general construction services, and ongoing land management services, with pricing determined per project rather than via published rate cards and contracts typically spanning multiple years. Customer segments are organized vertically: federal, state, and local government agencies as the primary segment (National Park Service, U.S. Forest Service, California Department of Fish and Wildlife, California Department of Water Resources, San Francisco Public Utilities Commission, Sonoma County Water Agency, San Mateo Resource Conservation District, and multiple municipalities); public utilities (Pacific Gas & Electric, served since 2013); nonprofit conservation organizations (California Trout, Golden Gate National Parks Conservancy, American Rivers, Trout Unlimited); and private landowners.

On April 30, 2025, Hanford was acquired by The Dutra Group, a family-owned Bay Area dredging and marine construction company that operates nationwide across all 50 states, as a wholly-owned subsidiary. The acquisition provided Hanford with additional capacity and financial backing while allowing the business to continue executing work autonomously. Founder Doug Hanford transitioned to Founder and Vice President; Ryan Abood (formerly Vice President of Dutra's Delta Division) was appointed Chief Operating Officer; and Aaron Johnson (formerly Vice President of Materials at Dutra) became Vice President of Operations at Hanford. In June 2026, the Twin Pines Belmont Creek Restoration Project was named Project of the Year by the American Public Works Association Silicon Valley Awards.
