The area of a lot shall be reduced dependent upon the slopes present on the lot as well as the presence of other natural features including wetlands, wetland transition areas, state open waters, floodway and riparian zones. Permitted density on the lot is based on the effective lot area. The building and impervious coverage are also computed on the effective lot area. |

(c) | Designed with underdrains. |
(d) | Designed to maintain at least a ten-foot-wide area of native vegetation along at least 50% of the shoreline and to include a stormwater runoff retention component designed to capture stormwater runoff for beneficial reuse, such as irrigation. |
(e) | Designed with a slope of less than 2%. |
(f) | Designed with a slope of equal to or greater than 2%. |
(g) | Manufactured treatment devices that meet the definition of "green infrastructure" at § 25-29.2. |
(h) | Manufactured treatment devices that do not meet the definition of "green infrastructure" at § 25-29.2. |
Best Management Practice | Maximum Contributory Drainage Area |
|---|---|
Dry well | 1 acre |
Manufactured treatment device | 2.5 acres |
Pervious pavement systems | Area of additional inflow cannot exceed three times the area occupied by the BMP |
Small-scale bioretention systems | 2.5 acres |
Small-scale infiltration basin | 2.5 acres |
Small-scale sand filter | 2.5 acres |
