Determine if the Project is subject to Redevelopment Requirements:

Site Area = 2.072 ac
Net Site Area = 2.072 ac
Existing Imp. Area = 0 ac
Percent Impervious (I) = 0 %
I <40%. Project Not subject to Redevelopment requirements.
Step 1 - Determine Stormwater Management Requirements

Initial Site Assessment (Site Data):
Existing Conditions

Total Disturbance Area: 90,272 sf
Soil Types: HSG A B C D
Area 90,272
Percent 100

Proposed Layout

Impervious Cover: 43,503 sf
Percent Impervious (I) 48 %

Determine RCNs for Wooded Conditions:

HSG A B C D
Area 90,272
Percent 100
RCN 38 55 70 77
Weighted RCN: 77
