Davenport regulates stormwater under Municipal Code Chapter 13.34, administered by the Public Works Natural Resources Division. Any development adding 5,000 square feet of impervious surface must retain or infiltrate the full 1.25-inch, 24-hour rainfall event on site.
Chapter 13.34 requires a stormwater management plan for development or redevelopment that cumulatively creates 5,000 square feet of impervious surface, or any project within 50 feet of a waterway. Structural best management practices must deliver 80% bacteria reduction and 100% retention or infiltration of the 1.25-inch, 24-hour storm, designed to the Iowa Stormwater Management Manual, SUDAS, and the Davenport Stormwater Manual. Post-construction facilities are inspected, maintained by the owner, and no certificate of occupancy is issued until they are built. The city's municipal separate storm sewer system operates under an Iowa DNR NPDES permit that prohibits illicit discharges to storm drains.
Enforced by the Public Works Natural Resources Division under Section 13.34.090: stop-work orders, municipal infraction citations, mandatory correction of illicit discharges, and forfeiture of the required 125% completion bond for unfinished stormwater facilities.
