OANThree simple points
A) Start with the correct Geography
B) Understand is no one correct answer
C) Whatever answer you get make it consistent with other chapters of the plan
![Page 7: Taking the devil out of the detail](https://reader033.vdocument.in/reader033/viewer/2022052907/55941c8b1a28abf02b8b4784/html5/thumbnails/7.jpg)
OANGeography
If you start with the wrong HMA geography
It is very difficult to correct half way through
If in doubt safer to include in the numbers you run
Caveat where needed; i.e. this LPA is poorly linked to the rest of the HMA
Note – applies to the main OAN document plus any updates
![Page 8: Taking the devil out of the detail](https://reader033.vdocument.in/reader033/viewer/2022052907/55941c8b1a28abf02b8b4784/html5/thumbnails/8.jpg)
OANUnderstand there is no one correct answer!
OAN is not a science
Key is to test the variables
Use the PAS note to help
So be prepared to defend any assumptions you make
By reference to sensitivity tests
![Page 9: Taking the devil out of the detail](https://reader033.vdocument.in/reader033/viewer/2022052907/55941c8b1a28abf02b8b4784/html5/thumbnails/9.jpg)
OANFinally
Whatever housing number you have
Ensure the plan is internally consistent
e.g. Households can support job growth
e.g. Households support the population assumed in the retail chapter….

Five year supplyEstablish your supply –what is deliverable: available, suitable and achievable?SHLAA / use practice guidance/ involve developers
Provide appropriate evidence• Windfalls• Lapse rates – non implementation allowance
Consistently apply the term ‘dwelling’ on both sides of equation
![Page 11: Taking the devil out of the detail](https://reader033.vdocument.in/reader033/viewer/2022052907/55941c8b1a28abf02b8b4784/html5/thumbnails/11.jpg)
Five year supplyBe clear what starting figure to use
Asses your shortfall and seek to deliver it within first five years
Evaluate whether there has been persistent under-delivery – apply appropriate buffer
Do the calculation ….
Then manage, phase and bring sustainable sites forward

Housing needs assessmentAligning jobs and housing
![Page 16: Taking the devil out of the detail](https://reader033.vdocument.in/reader033/viewer/2022052907/55941c8b1a28abf02b8b4784/html5/thumbnails/16.jpg)
What not to do• Buy a job forecast
• Translate the jobs into population into households & houses
– Assuming fixed commuting ratios
• Infer number of dwellings ‘needed’
• Why not?
– The forecast already assumes a given population
• And implicitly households and dwellings
– But not the same as you calculate at the end
• In economically buoyant areas usually fewer
– Because the forecaster’s jobs-to-population factors are different
– Especially commuting ratios are not fixed
• In real life commuting adjusts to supply-demand shifts
– Objectors have to ask just one question
• Show us the population figures behind your job forecast please
– And your numbers go in the bin
![Page 17: Taking the devil out of the detail](https://reader033.vdocument.in/reader033/viewer/2022052907/55941c8b1a28abf02b8b4784/html5/thumbnails/17.jpg)
![Page 18: Taking the devil out of the detail](https://reader033.vdocument.in/reader033/viewer/2022052907/55941c8b1a28abf02b8b4784/html5/thumbnails/18.jpg)
A real-life example• Experian forecasts 31,000 net new jobs in the plan period
• They also shows population growth
– In small print at the bottom
– 45,000 extra residents
– Taken from ONS 2010-based projections
• The planners didn’t look at that
• They calculate that 31,000 new jobs ‘needs’ 74,000 new residents
• Hence (say) 32,000 new houses
• Makes no sense
• Happens all the time
![Page 19: Taking the devil out of the detail](https://reader033.vdocument.in/reader033/viewer/2022052907/55941c8b1a28abf02b8b4784/html5/thumbnails/19.jpg)
What to do• Look at job forecasts
• Assuming the correct population
– As per preferred demographic projection
• Audit the forecasts
– Do you believe them?
– Are they consistent with policy aspirations?
– Are the commuting implications
• Credible?
• Acceptable / policy-friendly?
![Page 20: Taking the devil out of the detail](https://reader033.vdocument.in/reader033/viewer/2022052907/55941c8b1a28abf02b8b4784/html5/thumbnails/20.jpg)
What to do continued
• If Yes
– End of (almost)
– Make sure employment land policies use the same numbers
• If No
– Produce new job numbers (demand)
– Make sure they’re reasonably realistic
• Don’t get carried away
• Show why you think the forecast is wrong
– Translate into resident population > housing
• Not necessarily fixed commuting ratios
• Take an intelligent view
• Ideally working with the forecaster
• Understand how their jobs-to-population relationship works
• The models vary
– If you don’t like the result
– Reconsider the job number
![Page 21: Taking the devil out of the detail](https://reader033.vdocument.in/reader033/viewer/2022052907/55941c8b1a28abf02b8b4784/html5/thumbnails/21.jpg)
In short• Plan for enough housing to
– Support the number of jobs you are planning for
• Which may not equal latest (or any) forecasts
– Consistent with reasonable commuting patters
• Which may not be the same as today
• Keep it simple

Follow-up evaluation
• We employ Arup to follow-up on our work
– On reflection, was today actually useful?
– 10 mins of feedback in return for £100’s of support
• Our board use this to decide what we do with
our grant. If we don’t get positive feedback we
are unlikely to continue
