Cooroy RV Stopover-Flood Bushfire Hazard-Management Plan_FINAL

2           RISKS TO RV STOPOVER AREA USERS

2.1        Flooding

The area is subject to flooding from Cooroy Creek which is to the east and drains through the remnant bushland to
north. Cooroy Creek forms part of the Six Mile Creek catchment that flows into the greater Mary River catchment.

Cooroy Creek receives run-off from an intermittent stream (essentially an open drain) that crosses the north-west
corner of the RV Stopover site as per map below (blue line denotes waterways).




As part of the application for Material Change of Use, hydrology & water consultants were engaged to assess
potential flood impacts on the site for events of varying recurrence intervals – refer Dwgs 1-5 Attached.

The drawings demonstrate impacts for:

      a)    ARI – 2 yr
      b)    ARI – 10 yr
      c)    ARI - 100 yr
      d)    ARI - 500 yr
      e)    ARI - 2,000 yr
      f)    ARI – Peak 9999 yr

The likelihood of an event occurring in Annual Recurrency Interval (ARI) is:
     A – Almost Certain ARI 1
     B – Likely ARI 10
     C – Possible ARI 50
     D – Unlikely ARI100
     E – Rare ARI500
