The coefficient of runoff to be used in the calculations shall be as follows:
Streets | 0.95 |
Industrial areas | 0.95 |
Business areas | 0.90 |
Multifamily | 0.65 |
Residential areas (less than 2 acres) | 0.50 |
Residential areas (2 acres or more) | 0.40 |
Park areas and permanent open space | 0.35 |
The coefficient of runoff for undeveloped land shall be the appropriate coefficient for the ultimate land development as shown on the Future Land Use Map of the Comprehensive Plan.
