45m? was determined through the application of the Rational Method as outlined in QUDM. Refer to Bornhorst
and Ward’s Stormwater Management Plan for further information.

3.1.4 Stormwater Quality

The development, with a total developable area of 2,519m? does require stormwater treatment as per the
requirements set out in the State Planning Policy for a site with a developable area greater than 2500m2. A
proprietary stormwater quality device is proposed to treat stormwater runoff prior to its discharge from the site.
Refer to the proposed Stormwater Layout Plan within Appendix B and Bornhorst and Ward’s Stormwater
Management Plan for further information.

3.2 EARTHWORKS

Earthworks will be required to construct a level basement to facilitate the parking demands of the development
and to ensure the site can be adequately serviced. A detailed earthworks plan will be prepared as a part of the
detailed design operational works lodgement. Refer to the preliminary earthworks plan within Appendix B for
further information.

The site has been identified on Noosa Shire Council’s Natural Hazard: Acid Sulphate Overlay. As the proposed
development is to undertake filling and excavation below RL 20.0m AHD, it is anticipated that Acid Sulfate Soils
may be encountered. Therefore it is recommended that an Acid Sulfate Soil investigation be completed as part
of the detailed geotechnical investigation conducted for the site. If Acid Sulfate Soils are present, then an Acid
Sulfate Soil Management Plan will be required. All earthworks will be undertaken in accordance with Noosa Shire
Council guidelines. See Noosa Shire Council’s Potential Acid Sulphate Overlay Map in Appendix C for further
information.

3.3 ROADWORKS

Internal roadworks will be required to facilitate the development. Site access is proposed via a separate left in
only site access and left out only site exit onto Doonella Street. A 3m wide public thoroughfare easement is
proposed adjacent to the northern verge of the development. Refer to the Archicology Architectural Plans within
Appendix A for further details. Any proposed road works will be undertaken in accordance with Noosa Shire
Council Guidelines.

3.4 SEWER
3.4.1 Existing Infrastructure

There is existing sewerage infrastructure located within and surrounding the development site. An existing sewer
main drains east within Sidoni Lane to the north of the site. An existing sewer main drains east parallel to
Doonella Street within the southern boundary of the site. Manholes are located in the south east corners of lots
32 and 38 Doonella Street. Lot 30 and 32 Doonella Street are currently serviced via the sewer main running
within the southern boundary of each lot.

3.4.2. Proposed Infrastructure

It is proposed to service the development via a connection into the existing manhole in the south-east of the
site. The site naturally grades to this location. A Service Advice Notice application has been lodged with
