9. The lot area in square feet identified on each lot on the plat.

10. The location, approximate acreage, and dimensions of areas proposed for public use.

13. Maximum residential density to be completed in the development.

14. Buildable area envelope for each lot (for residential developments).

15. Proposed housing type/form for each lot (for residential developments).

16. Existing contour lines at two-foot intervals based on NAVD ’88 Vertical Datum.

17. The approximate curve radii of any existing public street or road within the proposed development. The approximate location, width, names, and curve radii for all proposed streets.

18. Existing uses of the property and locations of all existing buildings and designating which existing buildings are to remain after completion of the proposed development.

19. The location of areas subject to inundation, overflows from stormwater facilities, and/or within a designated one-hundred-year floodplain, all areas covered by water, and the location, width and direction of flow of all water courses.

20. Locations of existing natural features such as rock outcroppings, which would affect the design of the development.

21. A vicinity map showing the location of the proposed development in relation to the rest of the city.

22. The locations and dimensions of proposed lots and the proposed lot and block numbers. Numbers shall be used to designate each block and lot. Where a plat is an addition to a plat previously recorded, numbers of blocks and lots or parcels shall be in consecutive continuation from a previous plat.

23. Locations and widths of streets and roads to be held for private use and all reservations or restrictions relating to such private roads.
