It shall be the responsibility of the subdivider of every proposed subdivision to have prepared and certified by a land surveyor and/or professional engineer registered in the state, a complete set of construction plans, including profiles, cross-sections, specifications, and other supporting data for all required public streets, utilities, and other facilities.
(A) The final construction plans shall be based on the Drainage Plan, erosion plan and other information which have been approved with the primary plat, and shall be prepared and submitted prior to the secondary plat.
(B) Construction plans shall be prepared for all required improvements. Plans shall be drawn on standard 24 inch by 36 inch sheets at a scale of no more than one inch equals 50 feet, and map sheets shall be of the same size as the primary plat.
(C) Construction plans shall consist of the following:
(1) Topographic contours at intervals of one foot if the general slope of the tract is less than 5% or intervals of two feet if the slope exceeds 5% (contours shall be referenced to mean sea level elevations);
(2) Profiles showing existing and proposed elevations along center lines of all streets (where a proposed street intersects an existing street or streets, the elevation along the center line of the existing street or streets within 100 feet of the intersection. Approximate radii of all curves, lengths of tangents, and central angles on all streets);
(3) The Plan Commission may require, where steep slopes exist, that cross-sections of all proposed streets at 100 stations shall be shown at five points as follows: On a line at right angles to the center line of the street, and the elevation points shall be at the center line of the street, each property line, and points 25 feet inside each property line;
(4) Plans and profiles showing the location and typical cross-section of streets, including curbs and gutters, sidewalks, rights-of-way, drainage facilities, manholes and catch basins; 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; the location of street trees, street lighting standards and street signs; and exact location and size of all water, gas, or other underground utilities or structures; and
(5) Location, size, elevation, and other appropriate description of any other existing physical and natural features or facilities including trees with a diameter of eight inches or more (measured four feet above ground level), the points of connection to proposed facilities and utilities and the approximate high and low water elevations of all ponds, lakes, and streams. All elevations shall be referred to the U.S.G.S. datum plane.
