GRID CONTOURING ASSIGNMENT

The number shown is the R.L. of the land at the corner of the grid next to the number.

DRAW AND LABEL CONTOURS AT 1m INTERVALS OVER THIS GRID.

Using your contours, (and ignoring the grid lines) mark the route to be taken by a wheelchair friendly

path starting at the point marked by the blue circle (R.L. 27.5). The path must fall to the 24m contour

then rise till it meets the edge of the grid. The grade must always be 0.5%. (i.e. rise or fall 0.5m over

100m)

Each grid square represents 100m x 100m.
