In addition, the engineer or surveyor shall certify to the accuracy of the survey, the drawn plan, and the placement of the monuments;
(b) All straight lot lines and chords and radii of curved lot lines, defined in feet and hundredths of a foot by distances, and in degrees, minutes and seconds either by magnetic bearings or by angles of deflection from other lot and street lines;
(c) Lot numbers, lot areas both total and net area in both acres and square feet, and a statement of the local number of lots and parcels, together with post office address for each lot;
(d) A statement of the intended use of all nonresidential lots. A statement of restrictions of any type which exist as covenants in the deed(s) for all lots contained wholly or in part in the subdivision and, if covenants are recorded, including the deed book and page number;

Rights-of-way shall be shown and accurately identified on the plan, and easements shall either be shown or specifically described on the plans. Easements should be located in cooperation with the appropriate public utilities;
(h) Location, size, material used, invert elevation, and percent of grade of all sanitary and storm sewers and location of all manholes, inlets and culverts. This data may be submitted as a separate plan;
(i) If the subdivision proposes a new street intersection with a state legislative route, the intersection permit number(s) shall be indicated for all such intersections;

[1] Courses and distances with length in feet and hundredths of a foot of all straight lines and of the radius and the arc (or chord) of all curved lines with delta angles including curved lot lines, and bearings in degrees, minutes and seconds for all straight lines; and
[2] The width in feet of the cartway, right-of-way and of the ultimate right-of-way, and (in degrees, minutes and seconds) of the delta angle of all curved lines, including curved lot lines.
(2) The final plan shall be accompanied by the following supplementary data:
(a) Typical street cross-section drawing(s) for all proposed streets. Cross-section drawings may be shown on the final plan or on the profile sheets;
(b) Profile sheets for all proposed streets within the tract. Such profiles shall show at least the following information, properly labeled:
[1] Existing, natural profile along the centerline of each street;
[2] Proposed finished grade elevations at fifty-foot stations along the centerline of the street;
[3] The length of all vertical curves, and the station and elevation of the point of vertical curve and the point of vertical tangent;
[4] The station and elevation of all high and low points along the entire profile;
[5] The station and elevation of the point of intersection of all curves;
[6] Existing and proposed sanitary sewer mains and manholes, including invert and grade elevations, and size and type of pipe;
[7] Existing and proposed storm sewer mains, inlets, manholes, and culverts, including invert and grade elevations, size and type of pipe; and
[8] The percent of slope along the entire roadway profile with stations and elevations.
(c) The profile sheets shall be legibly drawn at one of the following sets of scales or any combination thereof:
[1] One inch equals 10 feet horizontal and one inch equals one foot vertical; or
[2] One inch equals 20 feet horizontal and one inch equals two feet vertical; or
[3] One inch equals 40 feet horizontal and one inch equals four feet vertical; or
[4] One inch equals 50 feet horizontal and one inch equals five feet vertical.
(d) All offers of dedication, and covenants governing the reservation and maintenance of undedicated open space, shall bear the certificate of approval of the Township Solicitor as to their legal sufficiency.
