The challenge of the 30-Year Plan for Greater Adelaide’s urban infill target

Getting to 85 per cent

The origins of the infill target

2008

2010

Planning and Development Review

The 30-Year Plan

50:50 ratio between infill and greenfield

70:30 ratio over 30 years


Context of higher population growth 1.2% – 1.3% p.a

4

The origins of the infill target

The 30-Year Plan High Growth Scenario

258,000 Total Dwelling Target

• 134,000 – infill – 52%

• 82,700 – fringe – 32%

• 41,300 – township – 16%

48%


5

Not counted as fringe

6

2010 - 2015

Aiming for the infill target

• Regional Targets – 2010 30-Year Plan

• LGA Targets – 2010 DPTI advice to LGAs

• Development Plan Amendments (Rezoning)

− Capital City

− Inner Metro

− Bowden

− West Lakes

− St Clair

− Northgate

− Minda (North Brighton)

− Glenelg


7

Five years in…

76%

New dwellings as infill in 2015

About 33% from minor infill

Only a small proportion are new housing forms

Target achievement

North Eastern Areas - Blair Athol - Enfield - Klemzig - Campbelltown

2010 - 2015

Infill Developments Mawson Lakes

Lightsview/Northgate North Western Areas - Woodville West - Seaton - Fulham Gardens

St. Clair

Shiedow Park

Southern Areas - Marion - Warradale - Ascot Park - Plympton - Park Holme

Fringe supply focus

But it wasn’t expected

Fringe Supply

Fringe Demand Now Zoned for Fringe

- Population growth slowed - Demand shifted

- Supply went to 30+ Years


10

2017 Update

The 30-Year Plan

• Reduced fringe land

• Legislated EFPA

• Expanded corridors

• 248,000 total dwellings estimated for high population growth scenario


11 Getting to 85% - PIA National Congress 2018

12

2017 Update to 85%

Now, a new target

Infill target increased significantly

• Overall percentage of infill

• Absolute numbers of infill dwellings

We have significantly underestimated the impact

of 80% of dwellings from infill in next 30 years


13

2017 Update

But how to get there?

• No Regional Targets

• No LGA Targets


14

City of Holdfast Bay

Case Study

Southern Adelaide Region

Infill Dwelling Target (2010) = 31,500

LGA Dwelling Target

DPTI Advised (2010) = 1600

Development Plan Amendments

Glenelg & Minda

Case Study

Significant misalignment with organic growth rate

30-Year Dwelling Requirement

= 4100

Southern Adelaide Region

Infill Dwelling Target (2010) = 31,500

LGA Dwelling Target

DPTI Advised (2010) = 1600

Development Plan Amendments

Glenelg & Minda

800

Major sites

16


Yield Analysis

1800

Residential Zone

= 2600

Assumed yield

• Relies on 2-for-1 growth

• Misalignment with pattern of development applications

• Assumes land is developable

• Policy more restrictive than indicated by yield

• MINDA Site accounts for 600 dwellings

• No yield analysis undertaken for Glenelg Ministerial DPA

• Glenelg added zero dwellings 2010-2015

• Questions regarding reliability of yield

• Supply insufficient for 30 years at current growth rate

• Serious undersupply if higher growth rates

Community Response

“Just because we are on a ‘transport line’ doesn't mean we need to increase population density. The bloody tram is

at capacity now…”

“Please leave medium density development to

the City of Marion...”

“This will add unnecessary pressures on our roads and change the feel of the suburb.”

“It would absolutely ruin our neighbourhood and really it

is an absolute joke…”

“Urban infill near transport does not reduce the number of cars

parked on street.”

“Do NOT support 'down zoning' of existing residential allotments to the proposed 'low density area‘… Encourag(ing) detached dwellings on large allotments is nonsensical…”


19

Is this a new response?

Stop Population Growth Now Party

1.0% population growth rate over 10 years

Others include: SOS, FOCUS, Burnside Resident Action Group, West Lakes, Lifecare

Is the response justified?

Quality of Development

Seaton – Western Suburbs

Intensity of Development

22


Cumulative Impact

Warradale – South-Western Suburbs

Is this just another form of POLLUTION?


State Planning Commission / DPTI / Planning Profession

• Community / social connection

• Sustainability

• Equity

• Self-sufficiency

• Health and wellbeing

23

So what’s the response?

Changing the Narrative


State Planning Commission / DPTI / Councils

• Face the quantum of change

• Understand the spatial implications

• Greater flexibility for density

• Tighter restrictions on housing pollution

• Address the challenge of infrastructure

24


Regional Planning


State Planning Commission / DPTI / Councils

• Better design outcomes

• Tighten policy on small-scale infill – performance driven

− site coverage

− car parking / driveways / hard surface

− landscaping

− sustainability

• Encourage/support consolidation of sites

− incentives

Planning & Design Code


26

Developing a new approach to infill

Current System

Site 2 • Developed in accordance to the

Residential Zone Policy. DPA required for intensive development.

Site 1 • Both portions will need to be

developed in accordance to the respective zones.

27

Developing a new approach to infill

Potential System

1

2

Site 1 and 2 • Catalyst site provisions provide

increased yield scenarios from larger/consolidated sites.

Site 1 and 2 • Assessed against broader policy

objectives for the corridor. • Focus on the interface issues with

adjoining land

Prospect Road as a Corridor

Neighbourhood-level Planning • Defines outcomes for the

corridor

Policy relevant to urban corridors and high density development exists broadly


28 Getting to 85% - PIA National Congress 2018

Ongoing, constant and evolving

• Issues education

• Strategic decisions

• Policy making

• Development assessment

The critical element

Community Engagement
