1              Introduction
1.1            Summary
A local flood study for the site was conducted by Cardno in 2006. The purpose of the study was to determine
the 1% Annual Exceedance Probability (AEP) local flood levels for the Noosa Care Carramar site. This flood
study was conducted using the 1D modelling program HEC RAS. Due to improvements in available flood
assessment since this time, and the potential impacts of climate change, the local flood study was required to
be updated. The results of the recent Noosa River Flood Study 2016 (WMA Water) were also required to be
referenced for relevant regional flood model levels.
The site is located at Lot 2 on RP177554, known as 186 Cooroy-Noosa Road. The site has an area of 4.047
hectares and has an existing aged care facility located on the western half of the site. Additional buildings are
proposed to be constructed on the site as part of a 48 bed dementia village. The location of the site is shown
on Figure 1-1.
The Flood Information Certificate from Noosa Council is provided in Appendix A.

1.2            Site Description
The site is located near the corner of Carramar Street and Cooroy-Noosa Road, Tewantin. The site is bound
to the south by Cooroy-Noosa Road, to the east by a tributary of Wooroi Creek and to the north and west by
residential allotments.
A dam is located on the tributary, with the dam wall located near the downstream boundary of the site. The
tributary merges with Wooroi Creek upstream of the crossing of Golf Course Drive and Griffith Avenue. Figure
1-1 shows the locations of the creek and tributary in relation to the site.
