SITE DESCRIPTION AND ENVIRONMENTAL ANALYSIS The project site is an existing flag lot with a stem portion containing the driveway which fronts on Ridgeway Avenue The 1.219 acre property was developed with a single family dwelling with attached garage, covered parking or storage area, retaining walls, bocci court and koi pond. The property is located within an existing residential neighborhood. The existing home is served by public utilities which are located within the bed of Ridgeway Avenue. A small portion of the property (approximately 3,000 sf) drains overland from a highpoint on the driveway stem towards Ridgeway Avenue. The remainder of the site drains overland from South to the North towards the rear of Lot 21.01 at which point runoff from the site is collected by an existing inlet and piped through Lot 21.01 to the Township storm sewer system. No existing stormwater management facilities were found on the site. There are no protected steep slopes on the site; slopes on the property are predominantly between 1.5% and 8%. The soils on the site are silt loam to loamy sand noted as BouB Boonton Urban Land within hydrologic soil type “C’, with a seasonal water table depth exceeding 80” in depth and a moderately low to moderately high infiltration rate of the most restrictive soil layer of 0.06 to 0.20 in/hr (USDA NRCS Soil Survey). On site soils testing revealed a depth to seasonal high water varying from 5’ to 7.5’ with an infiltration rate varying from 0.32’/hr to 1.00”/hr. The vegetation on the site is predominantly well established lawn, with a number of large deciduous trees located predominantly along the exterior boundary of the site with a lesser concentration within the site interior. A review of the NJ Geoweb site along with a site inspection by the engineer did not reveal any indications of wetlands, springs, seeps, intermittent or perennial streams or waterways or presence of protected species which might impact the development of the site. FACTORS CONSTRAINING DEVELOPMENT The on site soils testing consisting of four soil logs determined that the soils to the south of the property have an infiltration rate above 0.5”/hr which is the minimum allowable for stormwater management facilities which are infiltration based systems. The area to the north demonstrated infiltration rates below the minimum allowed for infiltration based

the minimum allowable for stormwater management facilities which are infiltration based systems. The area to the north demonstrated infiltration rates below the minimum allowed for infiltration based systems. PRESSED CURD D: RIDGEWAY AVENUE (VARIABLE WIDTH R.O. w.)
