How does it work? Input Black Box Output
Input • 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
Black Box • For each benefit type – Model (where available) of the economic benefit – Peer reviewed or “industry standard” models – Ability to include additional information if you open the black box! – Or leave default settings and go straight to outputs
Output
Economic value and benefit quantification

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 ....
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!
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

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
Influencing investment decisions • GI i incr ncreasing la land v value - encourages investment generally and allows sites to more easily be brought forward for development. • Reducing t the time me to o developme ment /r /reducing vo voids– bringing forward the date at which income is received.
