4 EXISTING STORMWATER DRAINAGE SYSTEM

4.1 Existing Infrastructure
Data obtained from Dial Before You Dig (DBYD), Noosa Council, Google Street View and a
detailed site survey identify the following existing drainage infrastructure:
    1. A series of existing stormwater pipes running along the western side of Val Crescent and
       a stormwater pipe adjacent to the northern site boundary within Val Cresent.
    2. Five existing stormwater gully pits within Val Crescent connected to the aforementioned
       stormwater pipes.
    3. A stormwater pipe contained within an easement that drains the above stormwater
       network. The stormwater pipe traverses the private property at 8 Val Crescent and
       discharges into the tidal Lake Doonella further west of the site.

4.2 Existing Drainage Patterns
Surface runoff from the existing site currently sheet flows from the southeast corner of the site
to the northwest corner and onto Val Crescent. Runoff from the existing residential roof areas
appears to discharge directly to the Val Crescent kerb via numerous kerb adaptors.

The surface runoff and roof water outlined above is eventually collected by the existing
stormwater infrastructure within Val Crescent and discharged to Lake Doonella.

Refer to Figure 4.1 below for a stormwater infrastructure schematic.
