Design drawings for proposed sewerage shall, in addition to meeting the applicable requirements of Env-Wq 703.01 through Env-Wq 703.03, include the following:

1. (a) Contour lines at 2-foot intervals and elevation of existing and proposed project area;
2. (b) The locations of all streams and other surface waters within the proposed project area, including their direction of flow and water surface elevations at the time of survey;
3. (c) 100-year flood elevations, if available;
4. (d) The boundary lines of the municipality, sewer district, or other area to be sewered;
5. (e) The location, size, and direction of flow of all existing and proposed sewers;
6. (f) Insets and detail sections with the scale shown directly beneath their subtitles;
7. (g) Plan and profile views in which the plan view is placed at the top;

8. (h) Plans clearly showing the location of:

   1. (1) All existing structures affecting the project;
   2. (2) Existing and proposed sewer outlets or overflows; and
   3. (3) All other utilities in the vicinity of the proposed sewerage;
9. (i) The locations of existing, proposed, and future sewerage as differentiated by appropriate symbols or designations;
10. (j) All topographical symbols and conventions as employed by the USGS;
11. (k) The horizontal distance or stationing between manholes, grades in feet per foot, and sewer sizes, types, and class;
12. (l) All sewer appurtenances depicted by symbols and referenced by a legend, with detail drawings of all sewer appurtenances accompanying the detail sewerage plans;

13. (m) Profiles indicating:

    1. (1) All manholes with manhole identification numbers;
    2. (2) Existing and proposed water main crossings with elevations;
    3. (3) Siphons;
    4. (4) Sewage pumping stations; and
    5. (5) In the case of stream crossings, the elevations of stream beds, flow lines, and the type of pipe;
14. (n) The sizes and gradients of sewers, surface elevations, first floor house elevations, and sewer inverts shown at or between each manhole;
15. (o) Finish grade elevations;
16. (p) Elevations of manhole inverts shown to the nearest 0.01 foot;
17. (q) All elevations referenced to a standard datum that is indicated on the plans; and
18. (r) As specified by the engineer, any special precautions or methods of construction necessary to prevent surface water pollution.
