 “Adamson Town Planning, specialising in providing higher order town planning advice”




    •   all habitable rooms are located 580mm or more above the DFE, with the planning scheme
        requiring 300mm;
    •   the extension to dwelling has been structurally designed to cater for a 1%AEP storm event;
    •   the depth and rate of flow across the access accords with the level of safety under the relevant
        standard (QUDM) and has a limited duration of 10-15 minutes; and
    •   regardless of the proposal to reconfigure the land, the level of risk remains the same for
        occupants of the extension.

Noosa Plan 2006
The application made is for reconfiguring a lot for the creation of two (2) allotments from a single
allotment. The subject land is located within the Noosa Heads Locality and is included in the Detached
House Zone.

Under the assessment table for development other than Material Change of Use (Table 9.10), the
proposed development is code assessable against the Noosa Heads Locality Code, Reconfiguring a
Lot Code, Landscaping Code and Engineering Works Codes.

Noosa Heads Locality Code
Under Part 9.7.1 of the Noosa Heads Locality Code, the overall outcomes are the purpose of the Code.
Under part 9.7.2 the most relevant overall outcomes include (a) and (nn). Having regard to overall
outcome (a), the dwelling on the new allotment:
   i.  is compatible with other uses and works in the locality;
  ii.  will maintain the safety of people and works;
 iii.  will not have a significant impact upon the amenity enjoyed by users or other premises; and
 iv.   avoids any significant adverse effect on the natural environment.

Having regard to overall outcome (nn), specially for the Detached House Zone:
   i.  the development has a low site impact and is a low-density development form having a
       domestic scale;
  ii.  maintains a high level of residential amenity;
 iii.  the allotment sizes and density are consistent with the character of the neighbourhood;
 iv.   the existing building style will remain unchanged and is befitting of the character of the
       locality, and is integrated with the site characteristics including slope and vegetation; and
  v.   no further building work is being proposed with landscaping provided amongst the existing
       buildings, with some trees and vegetation also being retained.

Under Table 9.11, the most relevant specific outcome is O16 (Flooding and drainage), with buildings
and other works designed and sited:
   a) with flood free habitable rooms being located at least 580mm above the DFE (1%AEP storm
       event) on Lot 1, a vehicle can safely traverse the access should that be necessary given the
       velocity and depth of flow is below the level of safety required and has a limited duration of
       10-15 minutes;
   b) the inundation of Lot 1 is relatively minor, short term and infrequent and does not affect any
       habitable rooms;

                                                                                             6|Page
