(A) General. Construction plans shall be prepared for all required improvements. Plans shall be drawn at a scale of no more than one inch equals 50 feet, and map sheets shall be of the same size as the preliminary plat.
(B) To be shown. The following shall be shown:
(1) Profiles showing existing and proposed elevations along centerlines of all roads. Where a proposed road intersects an existing road or roads, the elevation along the centerline of the existing road or roads within 100 feet of the intersection, shall be shown. Approximate radii of all curves, lengths of tangents, and central angles on all streets;
(2) The Commission may require, where steep slopes exist, that cross-sections of all proposed streets at 100-foot stations shall be shown at five points as follows: on a line at right angles to the centerline of the street, and such elevation points shall be at the centerline of the street, each property line, and points twenty-five feet inside each property line;
(3) Plans and profiles showing the locations and typical cross-section of street pavements including curbs and gutters, sidewalks, drainage easements, servitudes, 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, stormwater 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;
(4) Location, size, elevation and other appropriate description of any existing facilities or utilities, including, but not limited to, existing streets, sewers, drains, water mains, easements, water bodies, streams and other pertinent features such as swamps, railroads, buildings and utilities within the subdivision, and each tree with a diameter of eight inches or more, measured 12 inches 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 referred to the U.S.G.S. 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;
(5) Topography at the same scale as the sketch plat with a contour interval; of two feet, referred to sea-level datum. All datum provided shall be latest applicable U.S. Coast and Geodetic Survey datum and should be so noted on the plat;
(6) All specifications and references required by the city’s construction standards and specifications, including a site-grading plan for the entire subdivision; and
(7) Notation of approval as follows:
