2.0 SCOPE OF SERVICES Dynamic Earth’s scope of services pertaining to this report included evaluating the subsurface conditions at soil profile pit locations to estimate the apparent seasonal high groundwater level, collecting samples for laboratory permeability testing and performing in-situ basin flood testing. Four soil profile pits (identified as SPP-1 through SPP-4) were excavated at the site using a track- mounted excavator. Based on results of the initial subsurface investigation, relatively shallow weathered rock and machine refusal on apparent rock was encountered. As such, additional authorized scope of services included in-situ infiltration testing which included basin flood testing. Basin flood testing was performed within locations SPP-1 through SPP-3. Test locations were located within the area of potential stormwater management facilities and were backfilled to the surface with excavated soils at completion. Test locations located within existing pavement areas were backfilled to the surface with excavated soils and restored with asphalt at completion. The test locations are shown on the Test Location Plan included within the Appendix of this report. Environmental conditions were not evaluated by Dynamic Earth. The soils encountered were classified in general conformance with the U.S. Department of Agriculture (USDA) soil classification system. Observations were made for groundwater and/or redoximorphic features indicative of zones of saturation or seasonal high groundwater as indicated in the New Jersey Department of Environmental Protection (N.J.D.E.P) stormwater best management practices (BMP). Soil logs are included in the Appendix of this report. Undisturbed tube permeameter tests were collected in general accordance with New Jersey Department of Environmental Protection (NJDEP) Stormwater Best Practices Manual – Chapter 12: Soil Testing Criteria test methods on representative samples obtained from anticipated stormwater management facility infiltration depths. The results of the permeability testing are included in the Appendix of this report. Infiltration testing was performed at select soil profile pit locations in general accordance with New Jersey Stormwater Best Management Practices Manual- Chapter 12 using basin flooding test methods. Detailed results of the in-situ infiltration testing are included in the Appendix of

cordance with New Jersey Stormwater Best Management Practices Manual- Chapter 12 using basin flooding test methods. Detailed results of the in-situ infiltration testing are included in the Appendix of this report. 3.0 UNITES STATES DEPARTMENT FO AGRICULTURE (USDA) SOIL SURVEY Based on a review of the United States Department of Agriculture – Natural Resources Conservation Services (USDA-NRCS) soil survey the following soil resources are mapped underlying the site within the area of the proposed site improvements and are described below: Boonton loam, three to eight percent slopes, stony (BogB): This soil series is generally mapped within the northern portion of the site. The parent material is described as coarse-loamy basal till Altera 769, LLC c/o Altera Development 2 2530-99-006E
