Project Summary:

This project consists of drainage improvements within an existing drainage way from Galway Avenue to Sundowner Avenue. The southwest area of Sioux Falls has seen significant drainage issues during major rain events over the last several years, and the improvements are being constructed to address those issues. Work includes grading of the channel from Galway Avenue to Anthony Avenue, and construction of a storm water detention pond between Anthony Avenue and Sundowner Avenue. A low flow storm drainage pipe will be constructed adjacent to the channel from Galway Avenue to Anthony Avenue. A sump pump collection system will also be constructed along the north side of 61st Street.  Stub outs will be provided residents to hook up to if they choose.
