The proposed project will replace an existing fish passage barrier with a fish passable structure, regrade/realign 300 ft of the streambed channel, and enhance habitat. The project will restore salmon access to 2.74 linear miles of potential habitat; approximately 388 square meters (0.10 acres) of spawning habitat and 8,442 square meters (2.89 acres) of rearing habitat for the Southwest Washington ESU (evolutionary significant unit) of coho salmon, and the Southwest Washington DPS (distinct population segment) of steelhead trout. The primary objective is to replace an existing fish passage barrier with a fish passable structure. Culvert 021(64022)(00529) is an existing 2.13 m x 1.52 m (7 ft x 5 ft) corrugated metal squash pipe, located at MP 0.529 on Pigeon Springs Road, on Frase Creek. This culvert is under ownership of Lewis County and was calculated to be 0 percent passable due to a 1.16 m (3.8 ft) outfall drop, a slope of 2 percent and lack of substrate within the culvert. The culvert is ranked 18th for replacement within the upper Chehalis Basin and 11th for replacement within Lewis County. Replacement of this culvert is anticipated to restore access to an additional 2.74 linear miles of potential habitat; 8,442 square meters (2.89 acres) of rearing habitat and 388 square meters (0.10 acres) of spawning habitat. A priority index has not been generated for this culvert. test
