Terraphase has provided environmental assessment services to the Confederated Tribes of the Chehalis Reservation in Washington state to support land acquisition, Fee-to-Trust property transfers, and economic development initiatives. These efforts have played a key role in advancing both high-profile and community-focused tribal development projects.
Scope of Services
Terraphase’s work includes Phase I Environmental Site Assessments (ESAs) for pre-acquisition due diligence, environmental risk opinions, and Environmental Assessments (EAs) conducted under the National Environmental Policy Act (NEPA). Our services have supported commercial development, residential land purchases, and acquisition of floodplain and environmentally sensitive lands. These projects have required coordination with engineering teams, adherence to tight timelines, and management of public input and comment processes.

- Delivered EAs for the new Elder’s Center, and wastewater system improvement projects, and treatment clinic projects
