Village of Rye Brook, NY
SUBJECT: Sunrise RyeBrook Comparisions from Current approved to Adjusted plans
The following are calculations comparing the Current approved plans to the Adjusted plans.
I. Impervious Coverage:
Current Townhouse Impervious Coverage = 102,443 s.f.
Adjusted Townhouse Impervious Coverage = 102,913 s.f.
Net Increase = +470 s.f.
Current Back of House Impervious Coverage = 25,403 s.f.
Adjusted Back of House Impervious Coverage = 24,827 s.f.
Net Decrease -576 s.f.
Current Combined Impervious Coverage = 127,846 s.f. / 773,908 = 16.5% of total site
Adjusted Combined Impervious Coverage = 127,740 s.f. / 773,908 =16.5 % of total site
No Impervious change 0%

II. Building Coverage:
Current Townhouse Building Coverage = No change
Adjusted Townhouse Building Coverage = No change
Current Back of House Building Coverage = No change
Adjusted Back of House Impervious Coverage = No change
Current Townhouse Building Coverage = 40,505 s.f. / 773,908 = 5.23% of total site
Adjusted Townhouse Building Coverage = 40,505 s.f. / 773,908 = 5.23% of total site
No Change in Building Coverage
