NJ Surface Geology Map). Upper Stream Terrace Deposits are made up of Sand and pebble gravel, minor silt and cobble gravel; yellow, reddish yellow, yellowish brown. As much as 20 feet thick. (NJGS 2009).
Disturbance to the Upper Stream Terrace Deposits will occur because of grading, subsurface utility installation, septic disposal system installation, basin excavation, and associated earth disturbances. Such disturbances will displace and modify underlying sands and gravel, which will remain on-site during construction of the site improvements. There are no geologic limitations including faults or impermeable bedrock that may pose development limitations.
According to the Stormwater Management Report prepared by Yosef Portnoy, P.E., P.P., revised on June 5, 2025, the stormwater management system consists of two (2) small-scale surface infiltration basins and one (1) small-scale underground infiltration basin. The office building area stormwater will be managed by underdrained porous pavement areas, and a small-scale surface infiltration basin (Basin 1). The area will be managed by underdrained porous pavement areas, a small-scale underground infiltration basin (Basin 2) and a small-scale surface infiltration basin (Basin 3). All the proposed underdrained porous pavement areas have been designed to provide water quality treatment and to attenuate the rate of stormwater runoff.
The project will be serviced by an on-site sewage disposal system and public water. According to Civil Core, the system and all its component parts shall be constructed and installed to conform in all details to the requirements set forth in N.J.A.C. 7:9A (Unless otherwise specified) and to the engineering design which has been approved by the administrative authority. Departures from he approved design which become necessary due to circumstances which arise during construction and installation shall be approved by the design engineer and the administrative authority in accordance with N.J.A.C. 7:9A-3.7.
All excavation and grading shall be performed in accordance with the site plan which includes soil erosion and sediment control provisions to prevent the displacement and translocation of exposed geologic sediments. The proposed project will adhere to an approved Soil Erosion and Sediment Control Plan which will follow BMPs contained within the Standards for Soil Erosion and Sediment Control in New Jersey. This is necessary to avoid adverse impacts of displaced soil (geologic substrate) on adjacent lands. It will include engineering standards and vegetative standards to control land disturbance activities. Standards to be employed include:
Proper grading will protect against soil loss from erosion, enhance establishment of permanent vegetative cover and help to properly manage stormwater runoff, all of which will reduce off-site discharge of pollutants.
