Davenport sits on the Mississippi River, not an ocean coast, so waterway development is governed by its stormwater and floodplain codes. Any project within 50 feet of a waterway triggers stormwater quality review regardless of size.
Development within 50 feet of a natural or modified waterway, or that adds a new storm-drain outfall, must meet Chapter 13.34 stormwater quality standards regardless of project size, to protect environmentally sensitive riparian areas. Work in the floodway is tightly limited — stormwater treatment is not permitted there, and treatment in the 100- or 500-year floodplain must show a net ecological benefit. Riverfront and floodplain construction also follows Chapter 15.44, and work in the regulated floodway requires an Iowa DNR floodplain permit under Iowa Code Chapter 455B. Dredging or fill in the Mississippi additionally needs a federal Army Corps of Engineers Section 404 permit.
Building or grading within 50 feet of a waterway or in the floodway without required approvals draws stop-work orders under the stormwater and flood codes; unpermitted floodway work must be removed or the site restored.
