Municipal stormwater code promotes public health, safety, and welfare in compliance with state and federal laws. The Eastern Washington Phase II Municipal Stormwater Permit (Permit) requires jurisdictions to develop and administer code to:
· Prohibit non-stormwater discharges into their stormwater system.
· Require erosion and sediment controls, and other construction-phase stormwater pollution controls.
· Require post-construction stormwater controls.
