The post-construction runoff hydrographs for the current and projected two-, 10-, and 100-year storm events do not exceed, at any point in time, the pre-construction runoff hydrographs for the same storm events.
Reductions in peak flows are to be compared to pre-developed drainage area points of discharge in the event that drainage is re-directed in the post developed condition. Reductions are only required of the developed or modified portions of the project site.
As documented in the subsections above, the proposed peak flows meet the above reductions, thereby achieving off-site stability.
14. CONCLUSION
The proposed development has been designed to control stormwater runoff in a manner consistent with the existing drainage patterns. In addition, the proposed development satisfies the runoff quantity, quality and groundwater recharge requirements set forth by the Township of Jackson Land Use Ordinance, Pinelands CMP and NJAC 7:8 through the use of the proposed small-scale underground infiltration basins. With this stated, it is evident that the proposed development will not have a negative impact on the existing drainage conditions, water quality or groundwater recharge on-site or within the vicinity of the subject site.
