STEP 3 STATUS OF FEATURE

3.1 SEVERITY CODE: EMBANKMENTS
CUTS and NATURAL SLOPES

1 Minor shallow failure (<5m in length) 1 Cracks on embankment crest, road unaffected, no
subsidence, no other evidence of failure

2 Localised surficial loosening, localised evidence of fallen 2 Shallow failure on embankment surface, no crack or
material (rock) at base of slope depression on road

3 General evidence of fallen blocks and/or boulders at 3 Arcuate cracks on road and/or depression less than
base of slope 10cm - otherwise no mass movement evident

4 Failure affecting more than one berm but not the whole 4 Slope failure with arcuate cracks on road and/or
slope depression less than 10cm

5 Failure extending height of slope 5 Slope failure with extensive arcuate cracks on road
and/or depression greater than 10cm

*arcuate means 'in the shape of an arc' 6 Failure of slope and road - diversion required
