Surface Water Inventory.
Describe existing watercourses and water bodies that are partially or totally on the site and their relationship to the area of land disturbance. Calculate existing surface runoff from the site and the associated watershed, including the potential development of the remainder of the watershed. When the natural drainage pattern will be significantly altered, an analysis shall be conducted which will investigate flow, depth, capacity and water quality of the receiving waters. When required, floodplain areas will be mapped in consultation with the Department of Environmental Protection. Existing drainage structures shall be mapped and the capacity of the drainage network shall be determined. Additionally, wetland areas as defined by the Department of Environmental Protection and the U.S. Corps of Army Engineers shall be delineated.

Subsurface Water Inventory.
Describe the subsurface water conditions on the site both in terms of depth to ground water and water supply capabilities of the site. Where existing conditions warrant, provide detailed information regarding existing wells within 1,000 feet of the site relative to depth, capacity and water quality. Discuss the water supply capabilities of the adjacent areas and the recharge capabilities of the site.
