17.38.041 Parking Lot Stormwater Requirements.

(Added by Ordinance No. 174745; amended by Ordinance Nos. 180037 and 187904, effective August 19, 2016.)  Stormwater runoff from parking lots must be managed in parking lot interior or perimeter landscaping to the extent required by the Stormwater Management Manual and the Source Control Manual.  The Director is authorized to exempt activities, land uses, or identified sites from these requirements if use of parking landscape areas is not needed or desirable because of non-conforming or existing landscape areas.  All exemptions are described in the Stormwater Management Manual and the Source Control Manual.
