Description -- The project consists of cleaning out and restoring approximately 7,500 lineal feet of the existing drainage pathway along the historic railway grade (now Willapa Rails to Trail System) and replacing culverts as necessary to provide historic levels of protection to the surrounding areas (Adna High School and surrounding households). Phase I consists of about 4,200 linear feet of channel clearing eastward from Bunker Creek Road. Phase I channel clearing is to occur outside of wetland areas. Phase II consists of protection of the levee low point, replacement of Dieckman Road culvert, and ditch grading. Phase I will be completed 2/2013. Phase II will be completed 9/2013.
Flood Hazard Reduction Benefits -- The project would restore previously established drainage routes and provide additional flood protection for a concentrated group of residents, business, a fire station, a public park and a public school within the unincorporated Adna community.
