Protect the health and water quality of the Iowa River, Clear Creek, Muddy Creek, and all tributaries, lakes, and wetlands within these watersheds.
Address how stormwater is managed on new development and re-development within the community.
Reduce the degradation of our water resources that can result from pollutant and sediment runoff.
Minimize the damaging effects of localized flooding on residents, businesses, and property owners.
Within the first 18 months since the ordinance was implemented, 30 new developments or re-developments in Coralville implemented stormwater quality practices. These practices include bio-retention cells and swales, soil quality restoration, tree and infiltration trenches, and porous paving systems.
Post-Construction Stormwater Policy for Redevelopments
Over the next 20 years, an estimated 50% of development in Coralville will be redevelopment of existing properties. On July 12, 2016, the City Council approved Coralville's post-construction stormwater policy for redevelopment projects. View Post-Construction Stormwater Redevelopment Policy (PDF)
