"City of Chehalis will develop a master plan and banking proposal for flood hazard reduction and storage for a 156-acre basin located between the Chehalis River and Louisiana Avenue, and between Highway 6 and Airport Road in Chehalis. The City will demolish the old WWTP to create flood storage capacity in the floodplain of the Chehalis River. Phase I of this project included a grading plan with hydraulic analysis to demonstrate the positive impacts to the Chehalis River during flood stage. The project consists of the following four major Phases: Demo/remove wastewater facility; Create 10-acres wetland habitat; Monitor wetland/flood storage; Install recreational amenities."
