2.2       TOPOGRAPHY AND SITE DRAINAGE
The site is located on the eastern side of a north-south ridge line upon which a railway corridor lies. The site therefore
falls from the western boundary with Cooroy Connection Road to the eastern boundary with Trading Post Road and the
neighbouring eastern lot. The highest point on the site is near the intersection of Cooroy Connection Road and Pearsons
Road at RL 111 m AHD. The lowest point is at the northern end of the site between the existing northern dam and
eastern boundary at approximately RL 98 m AHD.

Stormwater runoff from external areas, 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
‘central gully’ and ‘southern gully’. The average grade of the central 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 ‘central dam’ and ‘southern dam’. At the northern end of the site
there is a third existing dam, referred to as ‘northern dam’.
