                                                                                         Page 9




Sediment basins are to remain in place until all roofs are connected to internal stormwater
pipes and driveway, concrete pavement and landscaping construction is at least 50% complete.
All new stormwater pits are to be protected from sediment infiltration by wrapping new pits
and grates in geofabric or covering appropriately with timber board. Silt fences are to remain in
place during the maintenance period until the site is established (80% ground cover) and
accepted "Off Maintenance" by Noosa Council.


5.3 Roadworks
Access to the proposed residential development will be provided primarily from the roundabout
at the end of Resort Drive and the connecting internal roads of Precinct F after precinct F is
constructed. The internal access road has been designed in accordance with Noosa Council’s
standard grades for minor access roads.

The internal road will have a width of 6.0m to provide adequate access and turning for
passenger cars and refuse collection vehicles. Various refuse collection bays with a maximum
grade of 5% will be provided along the internal road adjacent to the access to each basement. A
temporary turnaround area external to the site within Precinct F adjacent to the eastern end of
the internal road will be provided. The temporary turnaround area will be provided in an
easement in favour of Precinct E2 prior to Precinct F being constructed.

Refer Appendix E for the Refuse Collection Vehicle Turning Plan and the Siteworks and
Drainage Plans indicating the alignment, grades, location and levels of the proposed internal
road.

5.4 Stormwater Quantity Management
5.4.1 Legal Point of Discharge
The site currently drains to the west onto Resort Drive. As previously outlined, Precinct E2 is
part of the master planned Noosa Springs development. Accordingly, the existing stormwater
infrastructure contained within Resort Drive is the legal point of discharge for the site.

5.4.2 Noosa Springs Drainage Infrastructure and Lake System
A Master Drainage Report prepared by Ralph M. Grierson Pty Ltd dated June 1995 was prepared
for the entire Noosa Springs development. The report outlines the stormwater drainage concept
of the Noosa Springs development and summarises the internal lake system and associated
drainage infrastructure contained within the Noosa Springs development. The lake system and
drainage infrastructure has been designed to cater for the ultimate development of Noosa
Springs including Precinct E2.

5.4.3 Design Standards
The roof and allotment drainage system for Precinct E2 is to be designed to comply with:
    1. AS/NZS 3500.3:2003 - Plumbing and Drainage Part 3: Stormwater Drainage;
    2. the Queensland Urban Drainage Manual (QUDM), and the;
    3. The Noosa Council Planning Scheme
