         Issue - Stormwater Management Plan - Quantity
         Section 4.5.2 of the Stormwater Management plan does not detail how the existing stormwater
         infrastructure will take into account any increases in stormwater quantity and flows from the
         development of this site.

         Information Required
         Provide further information of how the site does not change the existing hydrological regime including
         drainage patterns and run-off quantity. Detail how the existing stormwater infrastructure for the Noosa
         Civic Shopping Centre and Hofmann Drive drainage systems, accounts for any increases or changes in
         runoff from the site.


Response:
Stormwater discharge from site is consistent with the overall Noosa Civic and Noosa Business Centre
masterplanning. The proposed development will connect into the drainage system for Noosa Civic and
Hofmann Drive. The sites minor flows will run through the existing pipe system whilst major flows will
overland flow down the internal roads prior to discharging to the creek to the south of the site in
accordance with the overall Noosa Civic and Noosa Business Centre development. There will be no
impacts to external developments as a result of the flows through the internal site system.


         Issue – Grass Swale construction on northern boundary
         The earthworks appear to encroach into Cov I. SP182845

         Information Required
         Provide information detailing how vegetation, and the Tree protection zones of this vegetation, in
         Covenant I will be protected during construction of the swale and batters along the northern boundary of
         the site.

Response:
All earthworks have been revised to be fully contained within the development site and do not extend
over the boundary. Any works completed within the vicinity of existing trees to be retained will be
completed under the supervision of the project arborist as required.

Should you require further information or clarification on any items within this request for information
response please feel free to contact the undersigned.

Yours faithfully
