Description:The Queensland Government broadhectare (residential land supply) study
quantifies the amount of land, which is predominantly greenfield
(undeveloped), available for future residential development. A number of
constraints (characteristics) are analyzed against parcels of land to identify
those that are physically suitable, potentially available under planning
scheme provisions and in the case of urban residential development, intended
to be serviced with reticulated water and sewerage. By comparing dwelling
projections against the residential land supply, an estimate of supply can be
calculated and any potential shortages identified.
The land identified in the broadhectare study is the first stage in the land
development pipeline. It includes parcels of land identified as suitable and
potentially available for future residential development. The study focuses on
land parcels greater than 0.25 ha.
The identified residential land is categorised according to development
potential as for either urban or rural residential use. The timing for land
development is based on local government infrastructure extension programs,
recent lot approvals and the development intentions of major developers.
Timing is divided into the following five categories:
0–2 years
2+–5 years
5+–10 years
10+ years
not specified.
The category ‘not specified’ also includes smaller parcels in existing
developed areas where development occurs randomly (depending on the owners’
intentions).
The spatial analysis process utilised in the broadhectare study involves
creating segments based on the Digital Cadastral Database (DCDB) over each
local government area. Each segment is then updated with data that impact on
the suitability and availability for residential development. Using rule-based
filtering, broadhectare land stocks are identified.
