1. PROPOSAL
The application seeks approval for a Reconfiguring a Lot - Residential. The proposal will involve
converting most of the existing backyard of the subject site into a rear lot. The two proposed lots
will be regular in shape and have a vertical, northeast-southwest orientation. The proposal does
not include a building envelope or plans for development in the new proposed lot and does not
include changing the existing dwelling house.
Vehicle access to the proposed rear Lot 2, is intended to be provided by an easement over
proposed Lot 1, along the length of the eastern side boundary. The applicant’s material identifies
the easement/access strip as approximately 4.5 metres wide and intended to service both lots,
with the existing Dwelling house retained on Lot 1 and new vacant Lot 2 located to the rear.
A minor portion of the existing Dwelling house gutter appears to extend within the proposed
easement area. This is not considered to raise a substantive planning concern given the
encroachment is minor and relates to roof drainage infrastructure only. It is expected that the
matters such as building maintenance, access and servicing can be appropriately managed
through final survey, easement documentation and any necessary building/plumbing compliance
requirements prior to plan sealing. The reconfiguration does not alter the existing dwelling house
side setbacks.
The locality and proposal plan are included below.

2. APPLICATION HISTORY
The application was properly made on 27 February 2026. An information request was made on 7
April 2026, which required a revised Stormwater Management Plan, demonstration of a Legal Point
of Discharge, and demonstration of compliance with PO12 of the Reconfiguring a Lot Code. The
applicant responded to the information request on 29 May 2026 to address these items.
An Amended Stormwater Management Plan was submitted as part of this response. This was peer
reviewed and updated prior being endorsed by Council’s Development Engineers.

3. SITE DETAILS
3.1. Site Description
The subject site is located at 25 Tulip Street, Cooroy, on Lot 58 RP 32777, and as such is located
within the Cooroy Local Plan Area. The land area is 1533m2. The subject site is of a regular,
rectangular lot shape with a consistent width of approximately 20m, a length of approximately 75m,
and a vertical, northeast-southwest orientation. The site has an existing dwelling house towards
the south which fronts Tulip Street, with an approximate setback of 13m and an approximate
frontage of 20m. The site cover of the existing dwelling house is approximately 14%. There is also
an existing shed which falls within the new proposed northern lot.
The backyard to the north makes up most of the site area, which constitutes where the new
boundary is proposed to occur. While most of the site’s open space is cleared, there is some
vegetation, however none is mapped under the Biodiversity, Waterways and Wetlands Overlay
Map. The site falls within both the Water Resource Catchment and the Water Supply Buffer Area
under the Regional Infrastructure Overlay Map. A small area within the new proposed northern lot
is defined as a Moderate Hazard Area under the Landslide Hazard Overlay Map. The site is not
subject to any other overlays.
The subject site is serviced by standard urban infrastructure services including reticulated water
and sewerage supply, telecommunications, electricity supply. The sewerage infrastructure
transects the site to the rear of existing dwelling.
3.2. Surrounding Land Uses
The subject site falls within a block of Low Density Residential zoning, many of which contain
secondary dwellings or relatively large outbuildings. At the eastern edge of the block is a strip of
Medium Density Residential zoning. Further to the east and north is more Low Density Residential
zoning. The site is situated 500m south of the Cooroy town centre. Directly across Tulip Street to
the south of the site is Noosa District High School, with a shed and the school oval directly facing
the site.
4. ASSESSMENT
4.1. Instruments for Statutory Assessment
Under the Planning Act 2016 the application must be assessed against each of the following
statutory planning instruments to the extent they are relevant to the development:
State Planning Policy;
South East Queensland Regional Plan;
Planning Regulation 2017; and
Noosa Plan 2020 (20 March 2026).
4.2. Noosa Plan 2020
The following codes from the Noosa Plan 2020 are applicable to this development:
Low Density Residential Zone Code;
Cooroy Local Plan Code;
Reconfiguring a Lot Code;
Works Codes;
Landslide Hazard Overlay
Regional Infrastructure Overlay
The subject site is located in Cooroy and is zoned Low Density Residential. The proposed use is
identified as a consistent use within the zone and is required to follow a code assessable
application process.
The application has been found to generally comply with all applicable statutory instruments. The
pertinent issues arising out of the assessment are discussed below:
Page 4 of 11
Page 5
Infrastructure Service
Acceptable Outcome AO12.4 of the Reconfiguring a Lot Code states:
AO12.4 If located in a Local plan area lots can be connected to Council’s stormwater drainage
network
The applicant has conceded that the proposed development would be unable to achieve
connection to the stormwater network, and as does not comply with AO12 of the Reconfiguring a
Lot Code. The proposal is therefore required to comply with corresponding Performance Outcome
PO12, which states:
PO12 New lots are located, sized and configured so as to ensure each lot is capable of
being serviced by appropriate levels of infrastructure including:
a. power supply;
b. telecommunications; and
c. where within Local Plan Areas
d. reticulated water supply;
e. reticulated sewerage; and
f. stormwater drainage.
Assessment
The proposal is considered to generally align with the intent of PO12 as the new lots are capable
of being serviced by appropriate levels of infrastructure. The site is already located within an
established urban area, with access to reticulated water, sewerage, power and
telecommunications services. The key servicing issue relates to stormwater drainage, as a direct
connection to Council’s stormwater drainage network is not available.
Notwithstanding this, the applicant has demonstrated through the amended Stormwater
Management Report that stormwater can be managed on site without creating an actionable
nuisance, consistent with the Legal Point of Discharge criteria in the Queensland Urban Drainage
Manual. The proposed stormwater strategy incorporates on-site detention and a level spreader
device to control the rate and manner of discharge to the nominated Legal Point of Discharge,
thereby reducing the potential for concentrated flows, erosion or downstream impacts on adjoining
land.
The amended stormwater approach has been reviewed and accepted by Council’s Development
Engineers. Subject to implementation of the approved stormwater measures, the proposed lots are
considered capable of being appropriately serviced and PO12 of the Reconfiguring a Lot Code is
achieved.
Rear Lot Proportion
Acceptable Outcome AO21.2 of the Reconfiguring a Lot Code states:
AO21.2 No more than 10% of lots within a subdivision are rear lots or lots accessed via
an access strip.
The applicant is proposing a rear lot proportion of 50% and as such the proposal does not comply
with Acceptable Outcome AO21.2 of the Reconfiguring a Lot Code. The proposal is therefore
required to comply with corresponding Performance Outcome PO21 of the Reconfiguring a Lot
Code, which states:
PO21 Rear (battle-axe) lots are created only where:
a. it would not be desirable nor practicable for the site to be reconfigured so that all
lots have full frontage to a road;
Page 5 of 11
Page 6
b. located in the Low density residential zone, Rural residential zone or Rural zone;
c. development positively contributes to the character of the neighbourhood;
d. development provides a high standard of amenity for residents and other users of
the rear lot and adjoining properties;
e. the lot is large enough to accommodate anticipated land uses including car parking
and manoeuvring;
f. development is not detrimental to the use and amenity of adjoining lots through loss
of privacy, sunlight or breezes once buildings are constructed;
g. vehicular access to rear lots will not have a detrimental impact on
lots adjoining the access strip due to excessive noise, light, dust, stormwater runoff
and the like;
h. access arrangements do not adversely affect the safety and efficiency of the road
from which access is gained;
i. their creation does not prejudice the anticipated development of adjoining land.
Assessment
The proposal involves reconfiguring 1 lot into 2 lots, one of which is a rear lot. The subject site is
within the Low Density Residential Zone and has a long, regular lot configuration, with the existing
dwelling house located toward the Tulip Street frontage. Given the existing siting of the dwelling
and the depth of the allotment, it would not be desirable or practicable to create two standard
frontage lots without substantially altering the established site arrangement or producing an
inefficient subdivision layout.
The rear lot is provided with sufficient area and dimensions to accommodate the existing shed and
future residential development, including private open space, vehicle access, parking and
manoeuvring. The proposed access arrangement utilises a single access strip from Tulip Street
and is not expected to compromise the safety or efficiency of the road network, having regard to
the low traffic generation associated with one additional residential lot.
The creation of the rear lot is considered to maintain the low density residential character of the
locality, which includes a pattern of larger residential lots, secondary dwellings and outbuildings.
Future built form on the rear lot can be appropriately managed through the applicable siting, design
and building requirements to protect the amenity of adjoining properties, including in relation to
privacy, access noise, light spill, sunlight and breezes. The proposed lot layout does not prejudice
the orderly development of adjoining land, as it is contained wholly within the subject site and
provides a logical rear-lot outcome for a deep residential allotment.
On balance, the proposal is considered to satisfy the relevant matters in PO21 of the Reconfiguring
a Lot Code.
