Let’s say the total site area is 600m2 and the highlighted elements have the following areas:
Gravel driveway | 24.00m2 |
Open deck with natural ground under | 15.70m2 |
Trees/shrubs/lawn | 300.00m2 |
Total | 339.70 |
Site coverage =( (Total Permeable Area)/(Site Area) ) x 100
=( 339.70/600.00 ) x 100
=56.6%, greater than 20%
