LATE RFI - Revised SWMP

 SITE DETAILS

     2.1. Existing Site Description & Drainage
The existing site, known in real property terms as Lot 3 RP 809059, is located at 35 Pavilion Street. The site contains
an existing an existing residential dwelling and secondary building, along with a free-standing shed structure. The
site covers an area of 2,574m² and is accessed by an easement over the existing driveway to Lot 4 RP 809059 (33
Pavilion Street). The site is located within an area zoned low density residential allotments, with dwellings to the
north, east and south, and undeveloped rural land to the west.


     2.2. Existing Drainage Patterns
The natural grade of the subject site would typically be around 10% falling to the west, however the site area
containing the existing buildings has been flattened creating a level pad with grades of between 2% to 5% based on
contour mapping of the region. A locality plan for the site is presented below in Figure 2.1 - Site Locality Plan (Noosa
Council Intramaps, 2022).

The run-off from the existing developed site typically drains overland as sheet flows following the existing
topography of the site towards the western boundary. Roof run-off is conveyed by downpipes which discharge
downstream of the dwelling to overland surface flows.

During inspection of the site, channelling of the driveway was observed that appears to indicate upstream flows from
the access driveway are discharging into the property, following the fall of the driveway through the site to the north.
Upstream flows from the adjacent properties to the east are also expected to flow through the site.
