       Figure 2 - Elevation Profile through site (based on 1m LIDAR data). ‘A’ marks site access from Upper
       Pinbarren Road; ‘B’ marks proposed lodge; Star marks bridge over creek; Circle marks level crossing.

There are two creek crossings on the site, the primary crossing located at the site entrance is via a bridge and a
second level crossing north of the caretakers house where a spillway overtops from the pond.

(It should be noted that both bridge and level crossing works are proposed to improve the flood resilience and
better notify site users of the risks at these locations.)

SITE FLOOD RISK
The primary source of flood risk to the site and in particular site users relates to flash flooding within the site
and wider catchment from heavy rainfall events. Specifically, there are number of ponds on the site which pick
up runoff from rainfall within the site and overflow down the site and into the main creek that forms the south
western border of the site. Although these ponds and other features are significantly lower than any of the
existing or proposed buildings on the site and would not pose direct risk to those buildings, access routes to and
from the site could be subject to inundation and flooding in more severe events. The purpose of this Flood
Management Plan presented in Appendix 1 is to provide a quick reference guide for the site owners and users
of the site in an emergency situation.

We trust this information is satisfactory for your current needs. Should you have any questions, please feel free
