Ecological Restoration & Stormwater Management LLC (ERSM)

What Ecological Restoration & Stormwater Management LLC (ERSM) does

Ecological Restoration & Stormwater Management LLC (ERSM) is a Pacific Northwest environmental services firm delivering stormwater management, ecological and habitat restoration, invasive and noxious weed management, erosion control, and environmental permitting and compliance. The company serves five primary customer segments: homeowner associations and property managers, land developers and home builders, tribal governments and conservation nonprofits, power companies and utility providers, and public jurisdictions and public agencies across Washington and Oregon. Operationally, ERSM maintains offices in Vancouver (WA), Portland (OR), and Tacoma (WA), and oversees maintenance and inspections of more than 200 stormwater systems, including Contech filters, BayFilter systems, and Oldcastle stormwater filters. The technical stack centers on field-deployed environmental services supported by GIS mapping, CESCL-certified stormwater inspections, SWPPP development, wetland delineations led by a Senior Wetland Scientist/Professional Wetland Scientist (PWS), and WSDA-certified herbicide application for invasive species control.

ERSM operates as a project-based professional services firm rather than a software platform. Revenue is generated through service contracts, recurring maintenance agreements, and one-time project engagements, priced on a custom project-by-project basis with free estimates. The go-to-market motion is consultative enterprise field sales targeting government entities, HOAs, developers, tribal governments, and utilities, supplemented by reputation-based referrals and a content-oriented website. The company is privately held by five founding partners—Aaron Gibson (Senior Restoration Ecologist), Ryan Masterman (Stormwater Analyst, CESCL), Brian Nikolas (Erosion & Sediment Control Analyst, CESCL), Austin Ada (Restoration Ecologist), and Cameron Tilley (North Washington Stormwater Analyst & Ecologist)—with no disclosed institutional investors, parent company, or funding rounds. The firm holds no patents, trademarks, formal partnerships, or AI/ML capabilities.

Comparable service portfolio to ERSM but with national scale and broader disciplinary depth.
