Auckland City CouncilIncorporating 7 cities and districts to become a Super City.
1.5 million people, 33% of the population of New Zealand.
The ChallengeA 30 year plan that includes the addition of 1 million people and 400 thousand dwellings.
Super City incorporates 4 regional plans and 7 district plans.
Politics and Media.
Capacity of Growth StudyDetermine how many people can be added to a region given planning provisions.
Scheduled every 5 years.
Previous plan required 4 years to finalize.
The Study
Assessments• Vacant land• Vacant potential• Redevelopment
potential• Infill capacity

Outputs
Developing CapacityThree methods:● Expand city limits.● Develop new land that lacks infrastructure.● Look for capacity in existing developed areas
(Infill).
Infill is the most cost effective.
Infill in the blanks
Spot the Infill: in-personLook out back of your house...● Do you have space to lawn bowl?● Is it reasonable to play AFL, rugby or football out
there?● Do you have a riding lawn mower?● Does your horse look happy?
There’s potential for people to be there instead.

Inputs
Algorithm
Residential Infill
Computed
Residential Planning Provisions● Area thresholds
● Building setbacks
● Access widths
● Density controls
A story of:
triangles and circles and squares and buffers.
Oh my!
Residential Infill Algorithm
TIN the parcel
Find the big triangles
Circle the triangles
Clip the circle from the parcel
Fit an oriented bounding box
Clip the box from the parcel
Clip the building offsets from the parcels and qualify area size
Qualify road access
Results
Commercial Infill
Computed
Commercial Planning ProvisionsMaximum number of stories
Recession planes
Yard setbacks
Upper level road setbacks
Start with flat boundaries
Boxes to represent floors
Boxes for setbacks and recessions
Recessions planes looking like staircases
Clip the setbacks/recessions from the infill
Smart MovesStaging
Repeating
Staged Implementation
RepeatabilityComputation only takes 1 to 2 days for 500,000 parcels.
Enables near-real-time scenario modelling.
What-if Scenarios?Planning provisions are stored in Excel file.Planners can tweak provisions like setbacks or densities without touching the modelling algorithm.Planners can run the model themselves.
Changing the RulesSmall provision changes can result in large increases in capacity.
Current Zoning Net Redevelopment Yield = 1065 new dwelling candidates
Test Zoning Net Redevelopment Yield = 2743 new dwelling candidates
In the EndCapacity Planning Evolved
SummaryStudy took 12 months to develop instead of 4 years.Data driven, evidence based approach can be scientifically criticized. Less emotional, less political, more accurate.Modelling algorithm is self-documented and repeatable.Assessments can now be regenerated in days.Planning staff are empowered to drive the scenarios.
