Green space refers to “Land area with landscaped or natural vegetation, including those vegetated areas located under upper story decks, porches and overhangs that are a minimum of seven feet from the ground at the lowest elevation”. Minimum green space requirements can be found in the Table of Dimensional Requirements, here.
To calculate your property’s green space, use one of the following formulas:
GS% = 100 – [(Square Footage of Impervious Surfaces / Square Footage of Property) x 100]
GS% = (Square Footage of Pervious Surfaces / Square Footage of Property) x 100
