RFQ: Deep River Engineering for Construction & Bidding 
Cover Letter


The Columbia River Estuary Study Taskforce (CREST) is seeking professional engineering services for an infrastructure and habitat restoration project in Wahkiakum County, Washington. CREST is working closely on this project with Wahkiakum County Public Works, who owns and maintains significant infrastructure within the project footprint. This project is located on the East Fork of Deep River, in the small unincorporated community of Deep River.

Beginning in 2022, Environmental Science Associates (ESA) won the preliminary and subsequent design contracts. ESA assisted CREST in developing conceptual design alternatives in the East Fork Deep River project area, including hydraulic modeling and 30% Designs for culvert replacements, fish passage improvements and habitat enhancements, and drainage improvements across the project area. In March 2024, ESA completed 100% Design Plans for Phase 1 of the project, which focused on replacing the failing culverts and tide gates on E Deep River Road with a new concrete tide gate structure and targeted channel constriction grading to improve drainage at a bottleneck approximately halfway between E Deep River Rd and Wirkkala Rd. With design work complete, the remaining engineering work includes engineering services during bidding and construction.

Due to funding requirements, CREST must re-advertise this Request for Professional Qualifications. CREST requires a firm with direct experience with overseeing projects involving Muted Tidal Regulator (MTR) tide gates and watershed-scale restoration activities in highly modified floodplains. If a firm does not address this key component in their proposal, CREST will eliminate the firm from further consideration.

All proposals must be received electronically by 4:00 pm, June 13th, 2025. Electronic proposals no larger than 20mb can be emailed to [email protected]. Late proposals and paper proposals will not be accepted. There will not be a site visit.




CREST's mission is to provide locally-based, high quality environmental planning, habitat restoration, and research services to the Columbia-Pacific Region."
