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

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

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

Topographical Information Contour Lines Closely spaced lines indicate steeper slopes

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

Topographical Information Contour Lines Profile drawings interpret contour plans

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

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

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