derived from the underlying basalt. The typical soil profile (as detailed in the survey) consists of slightly decomposed plant material to a depth of three inches; loam to a depth of five inches; silt loam to a depth of 30 inches; sandy loam to a depth of 47 inches; underlain by loamy sand to a depth of 72 inches below the natural ground surface (limit of the report). The depth to the groundwater table is reported to be greater than 72 inches below the natural ground surface (limit of the report). Boonton-Urban land, Boonton substratum complex, zero to eight percent slopes (BouB): Boonton-Urban land, Boonton substratum complex, zero to eight percent slopes is mapped within the southern portion of the site (within the area of the proposed stormwater management facilities) and is reported to have a similar soil profile to BogB, as detailed above. Boonton loam, zero to eight percent slopes, extremely stony (BogBc): Boonton loam with zero to eight percent slopes is mapped within a relatively small area within the western and northeastern portions of the site (within the area of the proposed stormwater management facilities) and is reported to have a similar soil profile to BogB, as detailed above. Urban land-Boonton substratum, zero to eight percent slopes (URBONB): This soil series is generally mapped within the southern and central portions of the site. The parent material is detailed as surface covered by pavement, concrete, buildings, and other structures underlain by disturbed and natural soil material. The typical soil profile (as detailed in the survey) consists of surficial material to a depth of 12 inches; silt loam to a depth of 47 inches; underlain by loamy sand to a depth of 72 inches below the natural ground surface (limit of the report). The depth to the groundwater table is not reported within the report. 4.0 RESULTS Detailed descriptions of the subsurface conditions encountered at each location are provided on the Records of Subsurface Exploration included herein. A summary of the subsurface conditions encountered within the soil profile pits is included below. 4.1 Subsurface Soil Profile The soil profile pits were performed within existing undeveloped areas and pavement areas. Test locations performed within existing undeveloped areas encountered approximately 12 inches of topsoil at the surface. Test locations performed

within existing undeveloped areas and pavement areas. Test locations performed within existing undeveloped areas encountered approximately 12 inches of topsoil at the surface. Test locations performed within existing asphalt areas encountered approximately six inches of asphalt at the surface. Beneath the surface cover, existing fill material was encountered generally consisting of sandy clay loam, silty clay loam, and sandy loam with various amounts of gravel. The existing fill material was encountered to depths ranging between approximately 2.8 feet and five feet below the ground surface; corresponding to elevations ranging between 476.0 feet and 463.2 feet. Beneath the existing fill material, natural residual soils were Altera 769, LLC c/o Altera Development 3 2530-99-006E
