Purpose of the Ordinance


  • 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.

Measuring Progress

 
Within the first 18 months since the ordinance was implemented, 30 new developments or re-developments in Coralville have implemented stormwater quality practices. These practices include bio-retention cells and swales, soil quality restoration, tree and infiltration trenches, and porous paving systems.
