Sustainable Parking Lot Design
1.
For purposes of this Section 4.3.J, "sustainable parking lot design" means a parking lot with parking spaces and drives that use innovative stormwater management practices, vegetation, and permeable paving materials to mitigate adverse environmental impacts of large expanses of paving and designed to reduce storm water run-off, manage water as a resource by promoting infiltration, protect local water quality through effective filtration and minimizes the heat island effect through effective landscaping.
2.
The maximum number of parking spaces allowed for a particular nonresidential use as set forth in Section 4.3.C.4.c may be increased, or the required minimum number of parking spaces for a particular nonresidential use as set forth in Section 4.3.C.4.a may be decreased up to 15% of the number of required parking spaces, by applying two or more of the following sustainable design principals:
a.
Bioswale or raingardens. As part of the overall storm water management plan for a property, bioswale or rain gardens constructed and used to reduce storm water run-off and treat storm water through filtration subject to the following:
i.
Drainage area map and calculations shall incorporate bioswale or rain gardens proposed within the parking lot and establish positive reduction in storm water drainage and sheet flow subject to review and approval by the Public Works Director;
ii.
Plant materials installed within the depression or swale area of a rain garden shall be of native variety and shall tolerate wet roots for the amount of time the rainwater takes to drain; and
iii.
Soil preparation, irrigation and fertilizer for the rain garden during installation shall be required.
b.
Permeable Pavement. Not less than 30% of the parking lot surface constructed with a porous or permeable pavement to allow transmission of water to aggregate base and subsoils. Runoff shall be temporarily stored in the base for infiltration into the subsoils and/or slow released to storm drain system. The three permeable pavement systems authorized by this paragraph b. are porous asphalt and concrete, permeable interlocking concrete pavers, and reinforced grass/gravel pavement systems. Additional types of permeable pavement may be considered subject to approval by the Director of Sustainability and Public Health and/or Public Works Director.
