Section 12.16.020 Purpose.

The purpose of this chapter 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 chapter seeks to meet that purpose through the following objectives:

1. Minimize increases in storm water runoff from any development in order to reduce flooding, siltation and stream bank erosion and maintain the integrity of stream channels;

2. Minimize increases in nonpoint source pollution caused by storm water runoff from development 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 development to not exceed the pre-development hydrologic regime to the maximum extent practicable;

4. Conserve storm water for beneficial use;

5. Limit development in flood plains;

6. 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. (Ord. 2002-1015)
