The purpose of this chapter is to set forth minimum requirements for managing the quantity and quality of runoff from all types of land uses throughout the city to achieve the following objectives:
A. Protect, preserve, and use natural surface and ground water storage and retention systems;
B. Improve the quality of stormwater runoff reaching surface water resources within the city and the Mississippi River by reducing nonpoint source pollution (including sediment) carried as stormwater runoff;
C. Minimize flood damage to residential, business, commercial and public structures and property, and protect against increased flooding caused by land disturbing activities and other projects;
D. Reduce volumes of stormwater runoff and the amount of impervious surfaces in the developed parts of the city;
E. Limit the rates and volumes, and increase the treatment of stormwater runoff, by managing stormwater runoff as close to its source as possible and mimicking the system's natural hydrology;
F. Minimize flood damage to residential, business, commercial, and public structures and property, and protect against increased flooding caused by land disturbing activities and other projects;
G. Minimize erosion and sedimentation;
H. Minimize damage from sediments resulting from eroded soil;
I. Regulate land disturbing activities to protect against erosion and sedimentation;
J. Implement soil protection and sedimentation controls to maintain health, safety, and welfare;
K. Protect and enhance fish and wildlife habitat and water recreational facilities; and
L. Secure the other benefits associated with proper management of surface and ground water. (Ord. 1326, 11-28-2016)
