Blackhawk Creek is a flashy urban stream that drains more than 4,500 acres through the south side of Davenport. It exhibited severe bank erosion of 8 to 14 feet. The creek is closely bounded by Indian Road on the west and single-family residences on the east. The creek banks continued to erode, threatening the stability of Indian Road and a sanitary sewer main adjacent to the creek. Due to the bank erosion, several manholes were exposed, as well as a few sanitary sewer pipes. The situation needed to be addressed to prevent imminent failure of the sanitary sewer system and maintain the integrity of Indian Road.
