SSc5.2 -Site Development: Maximize Open Space- Intention and Implementation |

Definition
Intention = Create a high "open space to footprint" ratio, Promote biodiversity

Implementation = Case 1: if impervious surface less than or equal to 50% of total site area: 1) Post-development peak discharge rate and quantity should be equal to or less than pre-development (for 1&2-year, 24-hour design storms) OR 2) Implement a stormwater management plan that protects receiving steam channels from excessive erosion by implementing a Stream Channel Protection strategy and Quantity Control strategies . Case 2: if impervious surface is more than 50% of total site area: 1) Post-development peak discharge rate and quantity should be 25% less than pre-development (for 2-year, 24-hour design storm) Additional Notes: For stormwater design with reduction of impervious surfaces: a) Examples of alternative surfaces include Rain gardens, vegetated swales & rainwater recycling. b) Examples of non-structural surfaces include vegetated roofs, pervious pavement, grid pavers. |
