Ground elevations on the tract, based on a datum plan approved by the city engineer, along all drainage channels or swales and at selected points not more than one hundred feet apart in all directions; show contours with an interval of not more than one foot if ground slope is regular and such information is sufficient for planning purposes.
7. Subsurface conditions on the tract, if required by the planning board: Location results of tests made to ascertain subsurface soil, rock and ground water, unless test pits are dry at the depth of five feet; location and results of soil percolation tests if individual sewage disposal systems are proposed.

9. Other conditions on adjacent land: Approximate direction and gradient of ground slope, including any embankments or retaining wall; character and location of buildings, railroads, power lines, towers and other nearby land uses or adverse influences; owners of adjacent unplatted land; for adjacent platted land, refer to subdivision plat by name, recordation data and number and show approximate percent built up, typical of lot size and dwelling type.
10. Photographs, if required by the planning board; camera locations, directions of views and key numbers.
11. Zoning on and adjacent to the tract.
12. When known, proposed public improvements: Highways or other major improvements planned by public authorities for future construction on or near the tract.

1. Streets: Names; right-of-way and roadway widths; approximate grades and gradients; similar data for alleys, if any.
2. Other rights-of-way or easements: Location, widths and purpose.
3. Location of utilities, if not shown on other exhibits.
4. Lot lines, lot numbers and block numbers.
5. Sites to be reserved or dedicated for parks, playgrounds or other public uses.
6. Sites, if any, for multi-family dwellings, shopping centers, churches, industry or other non-public uses, exclusive of single-family dwellings.
7. Minimum building setback lines.
8. Site data, including number of residential lots, typical lot size and acres in parks, etc.

E. Other Preliminary Plans. When required by the city engineer, the preliminary plat shall be accompanied by profiles showing existing ground surface and proposed street grades, including extensions for a reasonable distance beyond the limits of the proposed subdivision; typical cross section of the proposed subdivision; typical cross section of the proposed grading, roadway and sidewalks; and preliminary plan for proposed sanitary and storm sewers, with grades and sizes indicated. All elevations shall be based on a datum plane approved by the city engineer.
