b. c. d. 12/5/2005 considered include, but are not limited to, permeable pavements, decomposed granite, gravel, grasscrete and turfblock. Final approval of any surface is subject to the approval of the Engineering and Construction Division. Parking areas and access drives may be designed and constructed of permeable materials and permeable perimeter parking spaces are encouraged, subject to the approval of the Planning Division and Engineering and Construction Division. Where possible, drainage from parking areas and other impervious surfaces on a site shall be directed to landscape areas or other permeable surfaces for infiltration and/or detention of stormwater flows. Where possible, best management practices shall be incorporated into parking and landscape design to facilitate infiltration of stormwater prior to discharge from a site. Techniques to treat stormwater include, but are not limited to, using wheel stops rather than curbs to disperse drainage discharge, providing vegetated swales between rows of parking and/or at the perimeter of parking lots, use of permeable parking materials (hybrid parking lots) and creating parking groves within a parking lot. These and other best management practices are outlined in stormwater manuals, such as the "Start at the Source Handbook," prepared by the Bay Area Stormwater Management Agencies Association (BASMAA).
