gradually from the center of the site towards the north and south. A significant portion of the property has been disturbed by the existing residences developed approximately 40 years ago.

The upland portion of the project site is underlain by the following soils as depicted by the U.S. Department of Agriculture; Ocean County Soil Survey. Figure 3 is a copy of the Soil Survey with the site located. Soil Type % Slope Depth to SHWT* EvB –Evesboro Sand 0-5 >6.0' *SHWT = Seasonal High Water Table
The permeability of Evesboro Sand is typically rapid and the available water capacity is low. The depth to seasonal high water is typically greater than 6 feet. Evesboro is hydrologic soil group A. Soil test pits were performed at each stormwater BMP (Best Management Practice) to assess soil conditions and seasonal high water table. The depth to seasonal high water occurs at a depth greater than five (5) feet. The location of each test pit and log are shown on the subdivision plans.
There are no surface water bodies on or within 300 feet of the subject property.
The upper part of the Kirkwood Formation and the Cohansey Sand are hydraulically well connected and together function as an aquifer system. Underlying the Kirkwood-Cohansey aquifer system is the composite confining unit, a complex series of geologic units that, depending on location, can include as many as nine distinct units. The part of the composite confining unit of interest in this area ranges in age from Palecene to early Miocene and is made up of the Vincentown Formation, Manasquan Formation, Shark River Formation, Piney Point Formation, and basal clay of the Kirkwood Formation. Two minor aquifers are present in this part of the composite confining unit. The Vincentown aquifer consists of the Vincentown Formation, which is comprised of moderately permeable Quartz sand. The Vincentown aquifer is used as a source of water only in and near the outcrop areas, in the northwestern part of the County. The other minor aquifer, Piney Point aquifer, is confined and is composed of fin to coarse grained glauconitic quartz sand and shell beds.
The project will utilize public water supplies for potable water. The project will also recharge stormwater runoff to this aquifer by virtue of compliance with the New Jersey Stormwater Management Regulations.
Topographic contours and all existing feature onsite and within 50 feet of the site are depicted on the inserted site plans.
Wetlands are areas where the substrate is inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands include
