18.16.020 Purpose.
   The purpose of this chapter is to establish minimum stormwater management requirements and controls to protect and safeguard the general health, safety and welfare of the public residing in watersheds within this jurisdiction. This chapter seeks to meet that purpose through the following objectives:
   A.   Minimize increases in stormwater runoff from any development in order to reduce flooding, sillation, streambank/wash erosion, and maintain the integrity of channels;
   B.   Minimize increases in nonpoint source pollution caused by stormwater runoff from development that would otherwise degrade local water quality;
   C.   Minimize the total annual volume of surface water runoff that flows from any specific site during and following development to not exceed the pre-development hydrologic regime to the maximum extent practicable;
   D.   Reduce stormwater runoff rates and volumes, soil erosion and nonpoint source pollution, wherever possible, through stormwater management controls, and to ensure that these management controls are properly maintained and pose no threat to public safety. (Ord. 1397.18, § 1 (part), 2019)
