7. Topographical Information
Drawing describes surface features of building site
Contour information
Elevation
Benchmark
Contour lines
Contour intervals
Profile drawings
Spot elevations

8. Topographical Information Contour Lines
Elevations are vertical distances above sea level
Closed lines indicate hills or depressions

9. Topographical Information Contour Lines
“U” or “V” shaped lines that point toward higher elevations indicate ditches or streams

10. Topographical Information Contour Lines
Closely spaced lines indicate steeper slopes

11. Topographical Information Contour Lines
Lines farther apart indicate flat areas
Evenly spaced lines indicate uniform slope
Lines that cross indicate same elevation

12. Topographical Information Contour Lines
Profile drawings interpret contour plans

13. Topographical Information Drawing Contour Lines
Short dashed lines indicate existing topography
Solid lines indicate proposed changes

14. Topographical Information Drawing Contour Lines
Lines include numbers that indicate the elevation
Every fifth line drawn darker/bolder
Path/direction of contour line plotted by interpolating between known elevations

15. Topographical Information Engineering Measurements
Engineers scale
Measures in feet and tenths of a foot
