Concept Stormwater Management Plan
RSL Care – Cooroy Retirement Village

Stormwater runoff from areas external to the site, including part of the railway corridor and Cooroy Connection
Road, discharge to the site at two locations. Runoff drains through existing gullies from each of these locations.
The gullies are referred to as ‘northern gully’ and ‘southern gully’. The average grade of the northern gully is
approximately 1.8% and the southern gully is approximately 3.5% as measured from the western boundary to
the eastern boundary.

Each gully leads to existing dams on the eastern side of the site. Both gullies discharge across the eastern
boundary to neighbouring rural lots. The dams are referred to as ‘northern dam’ and ‘southern dam’.

The existing scenario stormwater catchment plan is presented in Drawing No. B07056-SK01 of Appendix A.
