      (7)   The names, locations and dimensions (cartway and right-of-way widths) of all streets, both existing and proposed, within a distance of 500 feet from the boundaries of the subdivision, showing any connections from the proposed streets to existing streets and to those proposed arterial and collector streets as shown on the Master Plan or Official Map, as adopted.
   D.   A preliminary stormwater management plan at the same scale as the site plan showing:
      (1)   All existing and proposed watercourses, including lakes and ponds, including water level elevations.
      (2)   Cross sections of watercourses and/or drainage swales at an approximate scale showing the extent of floodplain, top of bank, normal water levels and bottom elevations at the following locations:
         (a)   At any point where a watercourse crosses a boundary of the development.
         (b)   At fifty-foot intervals for a distance of 500 feet upstream and downstream of any proposed and/or existing culvert or bridge within the subdivision and within 1,000 feet downstream of the development.
         (c)   At fifty-foot intervals up to 500 feet upstream and downstream of any point of juncture of two or more watercourses within 1,000 feet of the development.
         (d)   At a maximum of five-hundred-foot intervals, but not less than two locations along each watercourse which runs through or within 500 feet of the development.
         (e)   When ditches, streams or watercourses are to be altered, improved or relocated, the method of stabilizing slopes and measures to control erosion and siltation, as well as typical ditch section profiles, shall be shown on the plat or accompany it. Where the Universal Soil Equation indicates a tract soil loss during construction in excess of 10 tons per acre per year, an erosion-sedimentation control plan in conformity with the recommendations of the Soil Conservation Service shall be furnished to and approved by the Board Engineer.
         (f)   The boundaries of the floodplains of all watercourses within or adjacent to the development.
      (3)   The total acreage in the drainage basin of any watercourse running through or adjacent to a development in the area upstream of the development.
      (4)   The total acreage in the drainage basin to the nearest downstream drainage structure and the acreage in the development which drains to the structure.
      (5)   The location and extent of drainage and conservation easements and stream encroachment lines.
      (6)   All existing or proposed storm sewer lines within or adjacent to the development showing size and profile of the lines, direction of flow and the location of each catch basin, inlet, manhole, culvert and headwall.
      (7)   The location and extent of any proposed dry wells, groundwater detention basins, retention basins or other water or soil conservation devices.
      (8)   Data showing that the developed tract will not discharge stormwater to contiguous neighbors in quantity and rate (cubic feet per second) that exceeds the tract discharge in its natural undeveloped state. The quantity of natural and undeveloped discharge shall be determined utilizing natural and developed parameters and an intensity of six inches of rainfall and/or a fifty-year, twenty-four-hour storm. The excess stormwater shall be suitably detained and discharged at a controlled rate not to exceed the above-mentioned natural site discharge. The detention devices' performance shall also be investigated for storms of lesser frequency. If no watercourse is available for discharge, a retention basin with groundwater recharge may be permitted after the applicant has demonstrated the feasibility of successful operations.
      (9)   A plan showing all on-site watershed divides and the appropriate drainage areas to the various collection system inlets, superimposed on a site plan of the development.
   E.   A preliminary utilities plan at the same scale of the site plan showing:
      (1)   The location of existing utility structures, such as water and sewer mains, gas transmission lines and high tension power lines on the subdivision and within 200 feet of its boundaries.
      (2)   Plans of proposed improvements and utility layouts, including sewer, water, storm drains, gas, telephone, television and electricity, showing feasible connections to any proposed utility systems. If private utilities are proposed, they shall comply fully with all township, county and state regulations. If service will be provided by an existing utility company, a letter from that company stating that service will be available before occupancy will be sufficient. When individual on-lot water or sewage disposal is proposed, the plan for such system shall be approved by the appropriate township and state agencies, and the results of percolation tests shall be submitted with the preliminary plat under conditions designated by the County Board of Health. Where applicable, the utility company letter must indicate that wet hookups will be available for each subdivided lot.
