How does it work?

Input Black Box Output

  • Data on the project

– Area, green infrastructure interventions – Type of green infrastructure

  • Woodland, green roofs

– Access improvements – Quality of improvements – designated site etc. – Population – House prices – Average wage

Input

slide-13
SLIDE 13
slide-14
SLIDE 14
  • For each benefit type

– Model (where available) of the economic benefit – Peer reviewed or “industry standard” models – Ability to include additional information if you

  • pen the black box!

– Or leave default settings and go straight to

  • utputs

Good bits

  • Has been used on many projects
  • Now at version 1.5
  • Talks the language of economic

development and regeneration.

  • Capable of producing useful

information to help get a better picture of the broad value of a project.

  • Seems to be acceptable even

with caveats

  • BUT ....
slide-21
SLIDE 21

Bad bits.

  • No tools for some benefits - yet
  • 11 economic benefits structure

good for communication but not for robust assessment.

  • Extensive use of benefit transfer –

but problems with evidence transferability.

  • Problems with evidence

robustness.

  • Range and sensitivity gaps.
  • Clunky!
slide-22
SLIDE 22

What next?

– Look to update the model – Increase the number of tools – Tackle the identified “bad” bits – Link to Geographic Information System

  • Potential for scenario

modelling

  • Potential for Dynamic

Interactive Cost Benefit assessments

Investments

Setting the Scene for Growth

  • £1.4m

– Green Streets – Community engagement – Address the lack of green infrastructure in the area

Local Sustainable Transport Fund

  • £500,000

– Improving access routes to encourage walking /cycling – Green Streets

Conclusion

  • GI Val enabled us to join the conversation!
  • GI now seen as a key part of the development

programme

– Relatively low cost kick start to an area that was struggling to attract investment – GI outside the development boundary had positive feedback from residents – GI as part of TIF programme

  • Anecdotal evidence of land price increase

  • GI i

incr ncreasing la land v value - encourages investment generally and allows sites to more easily be brought forward for development.

  • Reducing t

Urban GreenUP Kick-off meeting – 06/06/2017

URBAN GreenUP is the demonstration of an innovative methodology to re-naturing cities through NBS interventions, considering new technologies, towards the adaptation of the cities to fight against climate change.
