19.30.140 Storm Water and Drainage.
This section is included in your selections.
A. Each use shall provide for approved on-site or off-site detention or control of excess storm water runoff or drainage resulting from the use. No use shall cause downstream property owners to receive storm water runoff at a higher peak flow than would have resulted from the same event had the use or improvement not been present.
B. Storm water runoff or drainage shall be controlled and contained on-site except where adequate off-site storm drainage systems are available. Storm water runoff and/or drainage resulting from a use must be controlled so that water will not flow on to a public sidewalk or on to adjacent property. Drainage into city storm sewer or onto a city street must be approved by the City Engineer.
