EXISTING SLOPE ANGLE

means the maximum slope segment angle of all slope segments. For a Cut – slope segments are measured (on a horizontal plane); – within the extent of the cut; and – uphill of the cut, the distance to the boundary or 10m whichever is the lesser. For a Fill – slope segments are measured (on a horizontal plane); – within the extent of the fill; and – downhill of the fill, the distance to the boundary or 10m whichever is the lesser. A slope segment is a segment of sloping ground that falls generally at the same angle to the horizontal (slope segment angle) sustained over a distance of at least 3m, measured horizontally.
