The plan view and profile shall include as many sheets as are necessary to show adequately all improvements. Each sheet shall contain a plan view and a profile, and it shall show the page number and the number of pages.

      (3)   The latest revision date;

      (4)   The name or designation and right-of-way and pavement widths of each street;

      (5)   The centerline of each proposed street, with stationing to one-hundredths of a foot at points of intersection; points of tangents, points of curves, and street intersection, together with deflection angles, degree of curves, radii of curves, sub-tangent lengths, and lengths of curves;

      (6)   All proposed drainage structures, including manholes, catch basins, junction boxes, pipe storm drains, ditches, and other drainage facilities, including headwalls;

      (7)   The size, type, and location of existing and proposed easements;

      (9)   Location of bench marks with elevations referred to U.S.G.S. sea level datum;

      (10)   A typical section of road;

      (11)   Adjoining streets, drainage ways, or drainage structures affecting the design of the subdivision;

      (12)   Details of structures requiring special design;

      (13)   Soundings, if required; and

      (14)   Environmentally-constrained areas as defined in §§ 155.030 through 155.033.

   (B)   The profile shall show:

      (1)   Proposed road grades, designated by solid lines, with percent of grade and lengths of vertical curves;

      (2)   The elevations of proposed road grades to one-hundredths of a foot every 100 feet on uniform grades, every 50 feet on vertical curves, and at the center of all street intersections;

      (3)   The elevations and grades of proposed roadway ditches not conforming to road grades;

      (4)   The elevations, length, and grades of other existing and proposed ditches, drainage structures, manholes, catch basins, junction boxes, pipe storm drains, and other drainage facilities, including headwalls;

      (5)   Stationing to be shown along the bottom of each sheet;

      (6)   The original ground and final grade elevations, lettered at the proper station along the bottom of each sheet;
