(A) A topographic map of the land to be subdivided and such adjoining land whose topography may affect the layout or drainage of the development. The contour intervals shall be one foot when slopes are less than 2% and shall be two feet when slopes exceed 2%.
(B) On this map, the following shall be shown:
(1) The location of streams and other floodwater runoff channels, the extent of the floodplains at the established 100-year flood elevation where available and the limits of the regulatory floodway, all properly identified and sources noted. Note: the regulatory floodway may be measured from the effective FEMA map. However, floodplain boundaries shall be determined based on the 100-year flood elevation/profile and the topographic survey map prepared according to this section;
(2) The normal shoreline of lakes, ponds, swamps, and detention/retention facilities, their floodplains, and direction of inflow and outflow, if any;
(3) The location of regulated drains, farm drains, inlets, and outfalls, if any of record;
(4) Storm, sanitary, and combined sewers and outfalls, if any of record;
(5) Septic tank systems and outlet, if any of record;
(6) Seeps, springs, flowing, and other wells, that are visible or of record; and
(7) Soil names and their hydrologic classification for the proposed development when hydrologic methods requiring soils information are used.
