INCONSISTENCIES:
This application as currently proposed is inconsistent with the following standard(s) of the Jackson Township certified land use ordinances and the Pinelands Comprehensive Management Plan (CMP):
1. Stormwater Management:
A. Stormwater runoff (N.J.A.C. 7:50-6.84(a)6iii)
The Township land use ordinance and the CMP require that the stormwater runoff quantity standards contained in the New Jersey Department of Environmental Protection's (NJDEP) stormwater regulations (N.J.A.C. 7:8-5.6(b)3), as cross referenced in the CMP, be met for current and projected two-, 10-, and 100-year storm events as defined and determined pursuant to N.J.A.C. 7:8-5.7(c) and (d). No information has been provided to demonstrate that the proposed development will meet this standard.
B. Stormwater volume (N.J.A.C. 7:50-6.84(a)6iv(1))
The Township land use ordinance and the CMP require that any proposed development retain and infiltrate the total runoff volume generated from the net increase in impervious surfaces by a 10-year, 24-hour storm. Please note that the required volume must be met below the lowest outfall elevations within the proposed stormwater management measures.
Soil permeability (N.J.A.C. 7:50-6.84(a)6v(2))
The Township land use ordinance and the CMP require that stormwater infiltration facilities be sited in suitable soils verified by field testing to have permeability rates between one and twenty inches per hour. The submitted information indicates that all proposed stormwater management measures will be located in soils having a permeability rate greater than twenty inches per hour. This inconsistency may be resolved by removing soils below each Best Management Practice (BMP) and replacing those soils with a two foot layer of soil having an acceptable permeability rate (such as a K3 or K4 soil). Any replacement soils must also be replaced up to the elevation of the lowest outfall within each BMP.
2. Wetlands Protection (N.J.A.C. 7:50-6.14)
Based upon the scale of the above referenced site plan, a portion of the disposal field for the proposed commercial alternate design wastewater treatment septic system is located within 300 feet of the wetlands located south of the parcel. This inconsistency is resolvable by revising the plan to locate the entire disposal field at least 300 feet from these wetlands or by demonstrating that the disposal field is no closer to wetlands than the existing septic disposal field servicing the existing residential building.
Commission receipt of any county or municipal approval or permit for the development as currently proposed will likely result in the scheduling of a Commission staff public hearing to review the issues raised by the above-referenced inconsistency(ies).
