New York City Zoning Code - Permeable pavement requirements

Since 2007, New York City’s zoning code has required parking lots for community facilities to allow permeable pavements where appropriate. Parking lots with more than 18 spaces or more than 6,000 sq ft must capture stormwater through perimeter plantings and planting islands. The lot must be properly graded to drain runoff to those plantings. Both types of plantings must include trees of a certain diameter and spacing, and all vegetation must be from a list of pre-approved species. The objectives of these zoning requirements are to better manage stormwater on parking lots and reduce urban temperatures by providing shade. (City of New York Zoning Resolution, Article III, Ch. 7, Section 37-921).
