What Farallon Consulting does

Farallon Consulting is a 100% employee-owned environmental consulting firm founded in 1998 and headquartered in Bellevue, Washington, with 100-plus employees distributed across nine offices on the US West Coast (Washington, Oregon, and California). The firm provides a comprehensive suite of environmental consulting services including Phase I Environmental Site Assessments and Phase II subsurface investigations, contaminated site investigation and cleanup (including vapor intrusion assessment, remedial system design, sediment services, and emerging contaminants such as PFAS), civil and environmental engineering, permitting and regulatory compliance, insurance claim evaluation, and mediation and litigation support that leverages environmental forensics such as chemical fingerprinting, statistical modeling, and hydrogeologic analysis. The firm also offers specialized capabilities including FAA Part 107-licensed drone-based aerial inspection and mapping and natural resources assessment.

Farallon serves a diversified client base spanning real estate developers and investors, construction and industrial operators, municipal and federal government agencies, insurance carriers, law firms requiring expert witness testimony, and specialized verticals such as senior housing developers and healthcare facilities. Named engagements include work for Capital Industries, UCSF-San Francisco General Hospital, the City of Bellingham, Standard Oil/Chevron, IDX Tower Development, AIG Insurance, a National REIT, a Port of Seattle shipping operator, and Earle M. Jorgensen at the Lower Duwamish Waterway Superfund site.

The firm operates as a professional services business, generating revenue through project-based engagements structured as time-and-materials or fixed-fee contracts initiated via RFP responses, referrals, and direct relationship-based business development. There is no public pricing, no external funding, no parent company, and no disclosed revenue figure. In January 2024, Farallon acquired Grette Associates, an environmental and engineering firm specializing in natural resources and permitting support, signaling continued inorganic growth in the Pacific Northwest.
