  12. Design Excellence Since 1990 SSc6.1 Storm Water Design • Quality Control • Credit Intent • Limit disruption of natural hydrology by reducing the impervious cover, increasing on-site infiltration, and managing storm water runoff. • Potential Technologies & Strategies • Design the project site to maintain natural storm water flows by promoting infiltration. • Specify vegetated roofs, pervious paving, and other measures to minimize impervious surfaces. • Reuse storm water volumes generated for non-potable uses such as landscape irrigation, toilet and urinal flushing and custodial uses.

  13. Design Excellence Since 1990 SSc6.1 Storm Water Design

  14. Design Excellence Since 1990 SSc6.1 Storm Water Design

  15. Design Excellence Since 1990 SSc6.1 Storm Water Design • Vr=Volume Runoff • A=Area • Qr=Drawdown rate

  16. Design Excellence Since 1990 SSc6.2 Storm Water Design • Quantity Control • Credit Intent • Reduce or eliminate water pollution by reducing impervious cover, increasing on site infiltration, eliminating sources of contaminants, and removing pollutants from storm water runoff. • Potential Technologies & Strategies • Specify vegetated roofs, pervious paving, and other measures to minimize impervious surfaces and promote infiltration, thereby reducing pollutant loadings. • Use sustainable design strategies to design integrated natural and mechanical treatment systems such as constructed wetlands, vegetated filters, and open channels to treat storm water runoff.
