Problems to be solved:

Minor Hazards: Smaller long term/ongoing sources of potential damage (managed by good house-keeping); like creation of stable batters on soil & colluvium, or preventing further erosion & undermining of clay filled joints by sealing with concrete, or removing uncontrolled water flow via PVC piping.
Major Hazards: Larger, obvious sources of potential damage, like the big boulder or large trees falling on the house being removed or engineer stabilised.
