The purpose of this ordinance is to establish minimum storm water management requirements and controls to protect and safeguard the general health, safety, and welfare of the public residing in watersheds within the city. This ordinance seeks to meet that purpose through the following objectives:
1. Minimize increases in storm water runoff from any land disturbing activity in order to reduce flooding, siltation, increases in stream temperature, and stream bank erosion and maintain the integrity of stream channels;
2. Minimize increases in nonpoint source pollution caused by storm water runoff from land disturbing activity which would otherwise degrade local water quality;
3. Minimize the total annual volume of surface water runoff which flows from any specific site during and following land disturbing activity to not exceed the pre-land disturbing activity hydrologic regime to the maximum extent practicable; and
4. Reduce storm water runoff rates and volumes, soil erosion and nonpoint source pollution, wherever possible, through storm water management controls and to ensure that these management controls are properly maintained and pose no threat to public safety.
