General construction plans shall be prepared for all required improvements. Plans shall be drawn at a scale of not greater than 50 feet to an inch, and map sheets shall be of the same size as the preliminary plat. The following shall be shown:
   (A)   Profiles showing existing and proposed elevations along centerlines of all streets. Where a proposed street intersects an existing street or streets, the elevation along the centerline of the existing street or streets, within 100 feet of the intersection, shall be shown. Approximate radii of all curves, lengths of tangents, and central angles on all streets.
   (B)   Where steep slopes exist, and when required by the Plan Commission, cross-sections of all proposed streets at 100-foot stations shall be shown.
   (C)   Plans and profiles showing the locations and typical cross-sections of street pavements, including curbs and gutters, sidewalks, drainage easements, servitude, rights-of-way, manholes, and catch basins; the locations of street trees, street lighting standards, and street signs; the location, size, and invert elevations of existing and proposed sanitary sewers, storm water drains, and fire hydrants, showing connection to any existing or proposed utility systems; and exact location and size of all water, gas, or other underground utilities or structures.
   (D)   Location, size, elevation, and other appropriate description of any existing facilities or utilities, including, but not limited to, streets, sewers, drains, water mains, easements, water bodies, streams, flood plains, swamps, railroads, buildings, features noted on the Official Map or Comprehensive Plan, features at the point of connection to proposed facilities and utilities within the subdivision, and each tree with a diameter of eight inches or more, measured four feet above ground level. The water elevations of adjoining lakes or streams at the date of the survey, and the approximate high and low water elevations of such lakes or streams. All elevations shall be referenced to the U.S. Coast and Geodetic Survey datum plane. If the subdivision borders a lake, river or stream, the distances and bearings of a meander line established not less than 20 feet back from the ordinary high-water mark of such waterways shall be shown.
   (E)   Topography with a contour interval of two feet, referenced to sea-level datum. All datums provided shall be latest applicable U.S. Coast and Geodetic Survey datum and shall be so noted on the plan.
   (F)   All specifications and references required by the Design Standards and Specifications Manual, including a site-grading plan for the entire subdivision.
   (G)   Title, name, address, and signature of the professional engineer and/or surveyor, and date, including revision dates.
   (H)   The elevation of the 100-year flood plain for lands identified elsewhere by ordinance as including flood prone areas.
   (I)   Drainage improvements with calculations supporting the design of the drainage system.
   (J)   Notation of approval, as follows:
