Blackhawk Creek drains more than 4,500 acres through the south side of Davenport. The creek is closely bounded by Indian Road to the west and single-family residences on the east. The banks of the creek continue to erode westward, threatening the stability of Indian Road. Further, a sanitary sewer main exists between the creek and Indian Road. Several manholes have been exposed, as well as a few sanitary sewer pipes. The situation needed to be addressed quickly to prevent potential failure of the sanitary sewer system and maintain the integrity of Indian Road.

Bolton & Menk completed topographic survey, obtained regulatory agency approval, and designed bank stabilization measures to protect the sanitary sewer and Indian Road. The project stabilized approximately 3,350 feet of Blackhawk Creek. Both traditional and bioengineering stabilization methods were employed.
