The sugges7on is that all the ci7es housing supply can be delivered within the Se=lement Boundary. On this basis no sites outside the se=lement boundary are required.
This is a presump7on in favour densifica)on. This is a presump7on in favour of infill. This is a presump7on in favour of a saturated city. This is a big presump)on…
• presump)on prɪˈzʌm(p)ʃ(ə)n/ noun
1. an idea that is taken to be true on the basis of probability. "underlying presump7ons about human nature" the acceptance of something as true although it is not known for certain. "the presump7on of innocence” 2. behaviour perceived as arrogant, disrespecOul, and transgressing the limits of what is permi=ed or appropriate.
Is this deliverable, is this desirable?
Inside is complex and constrained Inside: Silver Hill – 300 down to 180 Police HQ – 297 down to 150 Fire Sta)on – 45 down to 16 On just 3 sites down 296 units Outside: Barton Farm – 2000 down to 2000

Cons

Sites inside and outside city boundary!
Combined capacity = 279 inside + 214 outside = 493!
493 deliverable less 421 target = 72 surplus
Only with the inclusion of suitable sites outside the SeXlement Boundary are the housing
numbers confidently deliverable.
Is this desirable?
Development outside the city boundary
Pros
– Proximity to facili7es – Limited impact on exis7ng residents ( Less Objec7ons) – Posi7ve impact on character and approaches to city – (Outside Conserva7on Area) – Improved access to the countryside – Code 5 viable – 40% Affordable Housing viable – Limited contextual constraints on density
Cons – Loss of low grade countryside
The tyranny of the ‘or’
Inside or outside Cellular renewal or comprehensive development
The beauty of the ‘and’
Inside and outside Cellular renewal and comprehensive development
Where are the best sites?

• Not all countryside is the same. Some7mes the countryside is less precious than the town.
• Some7mes the countryside is closer to town than the town!
• Some7mes the countryside is more viable and deliverable than the town.
• We need to carefully consider the most appropriate loca7ons for development on a case by case basis.
• We need to consider development in the east of the city.
• We need to consider sites inside and outside the se=lement boundary.
• We need to avoid planning by appeal.
Development outside the se=lement boundary can on occasions be be=er than development inside the se=lement boundary.
Its 7me to forget the planners black line on the map and look for land on a case by case basis.
