Background
Preservation of existing on-site vegetation retains values such as wildlife habitat, soil integrity and shading. Vegetation that is preserved is already established in the absence of supplementary irrigation. Also, these preserved areas reduce overall irrigation demand and stormwater runoff.
Requirements and certification
A percentage of the lot shall be undisturbed and in a natural vegetative state.
Percent of Lot Preserved | Silver | Gold | Commercial/Institutional |
30 or more | NA | 15 points | NA |
20 or more | NA | 10 points | NA |
10 or more | NA | 5 points | NA |
Preserved Vegetation Point Calculation |
(Total preserved vegetation area ÷ total lot area) × 100 = percent of lot preserved |
The Inspector must confirm the amount of preserved area during the site inspection and measure the preserved area to determine the percentage in doubt.
