SIOUX CITY -- A city project that is greening up Fourth Street while reducing storm water runoff has received a state award.
Sioux City's Promenade Improvements Project received the award for Renovated Civic Project from the 1,000 Friends of Iowa. It was one of 11 projects across the state receiving one of the group's Best Development Awards.
Situated on Fourth Street outside Promenade Cinema 14, the Promenade Improvement Project has eliminated half the concrete paving and replaced it with various elements including bio-retention cells -- landscape elements that capture and treat storm water runoff -- as well as tree trenches and soil quality restoration. The project was completed in September.
Prior to the renovation, the half-acre site was mostly impervious and received significant storm water runoff during rain events, which led to problems with drainage and wear.
Design and construction of the project cost $415,333.50, approximately $68,000 of which was covered by grant funds through the Iowa Department of Land Stewardship's Water Quality Initiative Program. Sioux City's project was one of 13 in Iowa that received grants.
