   5. (5) The topographic information within the area of each lot that is used to determine lot loading shall be prepared using the method referenced in (f)(1) or in (f)(2), above; and
   6. (6) If the property is not level, contour lines shall be drawn with contour intervals of 2 feet or 5 feet or if the property is level, a sufficient number of spot elevations that are obtained using the method referenced in Env-Wq 1003.07(f)(1) shall be shown on the plan; i
7. (g) The location of any part of the subject property that lies within a special flood hazard area;
8. (h) The location of any part of the subject property that is subject to deeded rights of flowage;
9. (i) The location of all surface waters and wetlands on or within 75 feet of the subject property, identified in accordance with Env-Wq 1014.06;
10. (j) If wetlands or surface waters are located on or within 75 feet of the area required by Env-Wq 1005.02(b)(2) or the ISDS location, a note certifying that all wetlands have been delineated in accordance with Env-Wq 1014.06 and identifying who performed the delineation and the month and year in which it was done;
11. (k) The location of existing and proposed culverts and dredge and fill areas;

12. (l) Proposed lot boundaries and, for each lot:

    1. (1) The area of the lot and the specific lot number;
    2. (2) Access to the lot from a street or other public way;
    3. (3) A delineation of all areas unsuitable for conventional subsurface disposal;
    4. (4) A delineation of the area(s) dedicated to sewage disposal; and
    5. (5) If the lot will have an on-lot well, the location of the well and its protective radius, with the protective radius depicted on-lot or in an area precluded from development;

13. (m) For each lot having shoreland frontage, the:

    1. (1) Length of the frontage; and
    2. (2) Topography of an area equal to or greater than the lot size determined by Env-Wq 1005.03 for the lot;

14. (n) The location of:

    1. (1) Each proposed or previously-approved ISDS or 4,000 SF area required by Env-Wq 1005.02(b)(2);
    2. (2) Each existing ISDS; and
    3. (3) Water pipes and existing buildings on the subject property and within any of the setbacks established in Env-Wq 1000 on abutting properties, or, if access to an abutting property is denied, a statement to that effect;

15. (o) All ledge outcrops within 75 feet of:

    1. (1) Any proposed EDA; or
