Culvert Retrofit for Aquatic Passage Restoration, Kirby Brook, Washington, CT
Project lead: Housatonic Valley Association
Total Cost: $83,410
EBTJV/NFHAP funding: $26,598
Partner funding: $56,812
Objectives
1) modify the Kirby Brook culvert by installing rock steps downstream of the site to back up water/increase the depth of water through the structure and eliminate the outlet drop to fully restore passage for fish and other aquatic organisms in 1.8 miles of stream upstream and a total of 8 stream-miles;
2) provide education and outreach about the environmental benefits and feasibility of AOP. Applicants plan a site tour, an educational program and 1+ educational signs for 50 people reached/educated, and 60,000 signage interactions.
This may be one of several demonstration sites in partnership with a recently created municipal culvert replacement cooperative to showcase how a culvert retrofit can be a good option when a complete redesign is both infeasible and not warranted from a safety or flooding risk perspective. This project will also benefit wood duck and American eel.
