Confluence Environmental Company

What Confluence Environmental Company does

Confluence Environmental Company is a privately held environmental consulting firm founded in 2007 and headquartered in Seattle, Washington, with a second office in Bellingham. The firm delivers environmental science, project management, and regulatory strategy services for public and private capital and restoration projects, employing approximately 30+ credentialed scientists including Professional Wetland Scientists, Certified Ecological Restoration Practitioners, and senior biologists with 20-30+ years of experience. Its service portfolio spans environmental project delivery, natural resource assessments (marine, estuarine, freshwater), mitigation and restoration design, regulatory strategy and permitting (Corps Section 404, ESA Section 7, NEPA/SEPA), GIS and remote sensing, and UAV-based aerial data collection, with a newer climate resilience and greenhouse gas reduction planning line launched in 2025-2026.

The business model is professional services: revenue is generated through project-based contracts acquired via competitive bidding, RFP responses, and ongoing client relationships with government agencies, tribal nations, and private-sector clients. Anchor engagements include the WSDOT SR 520 Bridge Replacement Program (a $4.6B program for which Confluence obtained nearly 75 separate permits and delivered 185 acres of habitat restoration), the Tulalip Tribes/BNSF railway culvert assessment covering 73 miles of Puget Sound nearshore, the $2B Mid-Barataria Sediment Diversion in Louisiana, and offshore wind services for South Fork Wind Farm. Differentiated technical assets include proprietary GIS databases, the Ecosystem Diagnosis and Treatment (EDT) model developed by Senior Aquatic Ecologist Eric Doyle in partnership with the Confederated Tribes of the Colville Reservation, and UAV data collection workflows.

The firm serves federal, state, and local government agencies, tribal governments, and enterprise clients across transportation, infrastructure, mining remediation, energy, and shellfish aquaculture. The company is certified as a Small Business Enterprise by Washington State (supporting set-aside contract access) and has earned multiple industry awards including the 2021 WSDOT Environmental Excellence Award, the 2022 Society for Ecological Restoration NW Special Award for Innovative Tools and Techniques, and the 2023 American Fisheries Society President's Fishery Conservation Award. Geographic reach spans the Pacific Northwest as the core market, with project-driven extensions into Louisiana, California, Oregon, Alaska, and New York.

Expansion highlights5 records

Broad incumbents

• AECOM: Global infrastructure consulting firm with extensive environmental services practice covering NEPA/SEPA, ESA compliance, water resources, and restoration. Competes for mega-program primes where Confluence typically operates as a subconsultant.
• HDR Inc. Engineering and environmental consulting firm with strong transportation and water practices that compete directly for WSDOT and similar DOT environmental work. Larger scale and broader geographic reach but overlapping service offerings in permitting and environmental documentation.
• Stantec: Global engineering and environmental consulting firm providing water resources, permitting, habitat restoration, and environmental assessment services. Competes for infrastructure and environmental program work across the PNW and beyond.
• ICF International: Global consulting firm with major environmental and climate practice, including climate resilience planning (overlapping Confluence's Yelm work), NEPA support, and regulatory advisory. Competes on municipal climate planning and federal environmental contracts.
• Tetra Tech: Global environmental and water resources consulting leader providing permitting, impact assessment, restoration, and climate resilience services at scale. Competes for the same large capital program primes (e.g., transportation, water infrastructure) but operates across a far broader service portfolio and geographic footprint.

Direct peers

• Anchor QEA: PNW-headquartered environmental and water resources consulting firm providing similar services in environmental permitting, habitat restoration, NEPA/SEPA documentation, and regulatory strategy across infrastructure and waterfront projects. Most comparable direct competitor given overlapping Pacific Northwest geography, federal/state client base, and marine/freshwater specialty.
• Kleinfelder: Engineering, environmental, and infrastructure consulting firm with strong presence in environmental permitting, NEPA documentation, and water resources. Similar mid-size consulting profile with comparable regulatory and natural resource service offerings.
• Environmental Science Associates (ESA): West Coast-based environmental consulting firm delivering planning, permitting, and restoration services for infrastructure, water, and natural resource projects. Active teaming partner on Confluence's BNSF culvert assessment project; competes for the same transportation and water infrastructure RFPs.
• Aspect Consulting: Pacific Northwest environmental and water resources consulting firm specializing in hydrogeology, environmental site assessments, and regulatory compliance. Comparable in scale, geography, and service mix, with similar mix of public agency and private developer clients.

Others

• Shannon & Wilson: PNW-based geotechnical and environmental engineering firm. Listed as a Confluence teaming partner on the BNSF railway culvert assessment rather than a direct competitor, but operates in adjacent environmental and infrastructure consulting space.
