E. What design criteria and/or site changes would be required to reduce the percentages in C and D above? The parking area would need to roughly match the existing driveway slope, which isn't practical since this would make it difficult to comply with ADA requirements. F. Specify site’s hydrologic soil group (HSG) percentages: HSG A: HSG B: HSG C: 100% HSG D: G. Specify percentage of each HSG that will be permanently disturbed: HSG A: HSG B: HSG C: 100% HSG D: H.Locating site disturbance within areas with less permeable soils (HSG C and D) and minimizing disturbance within areas with greater permeable soils (HSG A and B) can help maintain groundwater recharge rates and reduce runoff volume increases. In light of the HSG percentages in F and G above, what other practical measures if any can be taken to achieve this? None I. Does the site include Karst topography? Yes: No: X If yes, discuss measures taken to limit Karst impacts: New Jersey Stormwater BMP Manual • Appendix A: Low Impact Development Checklist • February 2004 • Page A-7
