PLANNING & ENVIRONMENT COMMITTEE MEETING AGENDA                               6 DECEMBER 2016


The initial staff review of the draft third Briefing Note and GIS output took over three months to
complete, resulting in a revised final document being agreed with Unitywater in August 2016. The
revisions made only related to minor corrections and to ensure consistency with the model’s
exported excel spreadsheet LGIP classification totals.
It is important the actual “Base” and “Ultimate” potential data be accurate since this forms the
basis for all discussions within Council and with the State regarding the remaining potential future
development growth of the planning scheme. The in-between 2016, 2021, 2026 and 2031
forecasts are simply estimates that can be adjusted to meet the required State’s projected
(census resident) growth forecasts.
The initial review revealed that a small number of properties did have some incorrect base
development data and, while not significant in the overall totals, it is proposed to be accounted
for and corrected in the final review and assessment for determining the final LGIP tables. The
discrepancies would then be provided to Unitywater for correcting their DMaTT model property
data for updating to the next version and new base date.
The final staff review of GIS outputs primarily relating to ultimate capacities and associated
adjustments to the property LGIP details is taking much longer than anticipated. This is due to
the sheer volume of the individual property data, limited availability of specialised staff time to
dedicate solely to this task and the computing speed of the IT systems necessary to undertake
the review. It is anticipated that this final review and any associated adjustments may take a
further 4 months plus to complete.
In order to progress the LGIP to meet the desired project plan timeline for submitting a draft LGIP
to the first State review, it is recommended the Council proceed with the LGIP Planning
Assumptions per the DMaTT Briefing Notes and adjust to align with the “residential” population
and dwelling forecasts prepared by the Queensland Government Statistician. This is further
discussed in section 2.4.
Should there be any significant discrepancies discovered following the staff final review of the
DMaTT GIS output data, then this can be reported to Council for adjustment prior to the second
State review. If any significant discrepancy arises, is anticipated that this will        relate
predominantly to ultimate capacities, it will therefore not impact the ensuing infrastructure
network planning projects to cater for projected development growth within the required 10 to 15
year horizon (i.e. to the year 2031).
2.   Planning Assumptions for the new LGIP
The Planning Assumptions proposed for the new LGIP must comply with the Statutory Guideline
03/14 which comprises the following items:
2.1. Base Date and Projection Years
The LGIP is required to be prepared for a designated “Base Date” and projection years to accord
with future Australian Bureau of Statistics census years for at least a period of 15 years and the
estimated ultimate capacity of the planning scheme.
As preparation of the LGIP first commenced with the Unitywater DMaTT model base data at June
2014, it is suitable that the LGIP “Base Date” also be set at mid 2014 with the future projection
years for mid 2016, 2021, 2026, 2031 and estimated ultimate capacity of the planning scheme.
2.2. Development Types and Uses
The planning assumptions must be prepared for a limited number of development types where
uses under the planning scheme must be grouped into broader types of development that
adequately reflect differences in infrastructure demand for the trunk infrastructure networks.
For the new LGIP, it is proposed that the planning assumptions be grouped and stated in
accordance with the required minimum statutory guideline development types and this is
provided in Attachment 1.
