(A) Number of copies. The applicant shall provide three sets of construction plans and two sets of the pavement design report.
(B) Format.
(1) Construction plans shall be 24 inches by 36 inches, with a margin of two and one-half inches on the left side of the sheet and appropriate margins on the other three sides. Construction plans shall be drawn at a scale of 50 feet equals one inch.
(2) Where more than one sheet is necessary to accommodate the entire area to be subdivided, an index sheet showing the entire subdivision at an appropriate scale shall be attached to the plat.
(C) Contents. The plans and profiles for street, alley, cross walkway and drainage easement improvements submitted shall include the following information:
(1) Typical sections showing:
(a) The proposed pavement width, type, thickness and crown;
(b) The proposed curb and gutter type, and the location in relation to centerline and exposure;
(c) The proposed parkway grading slopes;
(d) The proposed locations and type of wheelchair ramps;
(e) The location of traffic signal conduit; and
(f) Construction details of all drainage, including dimensions, reinforcing and components, such as grates and manhole covers. The information shall be given for each different type of street and alley in the subdivision.
(2) Street specifications and property boundaries showing:
(a) Alignment of each street, alley, cross walkway and drainage easement showing a beginning and an ending station;
(b) Each deflection angle of the centerline and the station of the point of intersection;
(c) The station of the point of curvature and the point of tangency of each curve;
(d) The station and angle of intersection of each intersection with another street, alley or drainage easement;
(e) The station and radius of each curb return;
(f) The location of adjacent right-of-way lines;
(g) The location and limits of sidewalks and curbs of each street;
(h) The location of each drainage structure;
(i) The location and size of all storm sewers; and
(j) The length, width, and thickness of the cement-stabilized base.
(3) Storm water management facility information including:
(a) The top of curb grade at each curb end, each 50-foot station, and each end of each curb return;
(b) The centerline grade at each end and at each 50-foot station of alleys and drainage ditches;
(c) The gradient of each tangent grade and the location and length of each vertical curve;
(d) The direction of storm drainage flow at each intersection;
(e) The flow-line elevations of each drainage structure; and
(f) The flow-line elevation of each storm sewer at each point of change of grade, at each end, and at the intervening gradients. The profiles of streets, alleys and drainage ditches shall show the natural ground at adjacent property lines and the proposed centerline.
(4) Scale, north arrow, date and plat number of the associated plat. Plans and profiles shall be drawn to scales of 50 feet equals one inch horizontally and five feet equals one inch vertically, unless different scales are approved by the Code Enforcement Officer; and
(5) All street and alley plans and profiles shall bear the seal of a professional engineer.
