Yakweakwioose First Nation Stormwater Outfall

Yakweakwioose First Nation is developing a new subdivision at Yakweakwioose First Nation Reserve No. 12 (Yakweakwioose 12), in Chilliwack, BC. The proposed works include construction of a stormwater outfall into Chilliwack Creek. Works will include clearing of upland vegetation prior to the excavation and installation of underground stormwater infrastructure, including storm sewer pipes; junctions (with surface openings); and a stormwater control system.


These works will occur within designated riparian and aquatic critical habitat for Salish sucker (Catostomus sp. Cf. catostomus).


Fish and fish habitat offsetting measures will be implemented post construction, and will be monitored for 10 years.
