  3. Urban Bare Water Trees Open Space Impervious

  4. Resource Teams • Economy • Air • Water • Land • Overall

  5. Resource Team Framework • Define extent of topic area • Determine benchmarking of existing conditions • Identify goals for the topic • Define metrics used to achieve goals • Identify Targets of Opportunity for implementation • Summarize recommendations

  6. Economy Resource TeamExtent of Topic Area • Residential, industrial, commercial property values • Environmental mitigation cost savings • Economic value of recreation areas • Ecotourism value • Food production value • Reducing maintenance costs • Green jobs • Reducing health care costs

  7. Economy Resource TeamBenchmarking Existing Conditions • Residential, industrial, commercial property values • Identify parcel values near green infrastructure amenities (e.g. parks, trails) • Assume 2-6% of value is from GI (Land Policy Institute, 2008)

  9. Economy Resource TeamBenchmarking Existing Conditions • Environmental mitigation cost savings Source: Urban Ecosystems Analysis SE Michigan and City of Detroit, American Forests, 2006

  10. Economy Resource TeamBenchmarking Existing Conditions • Economic Value of Recreation Areas $401/acre Source: Economic Impact of Michigan’s State Parks: A Case Study of Ogemaw County, Land Policy Institute, 2007

  11. Economy Resource TeamBenchmarking Existing Conditions • Ecotourism Value • Identify ecotourism activities • Gather existing data (Lake St. Clair, Pure Michigan, MDNR’s Recreation Passport Program, etc) • Example: Licensed hunters contribute $1 billion annually to MI economy (3rd in nation)

  12. Economy Resource TeamBenchmarking Existing Conditions • Food production value Source: Census of Agriculture, USDA, National Agriculture Statistics Service, 2007

  13. Economy Resource TeamBenchmarking Existing Conditions • Reducing maintenance costs Source: Wayne County Department of Public Service, 2011

  14. Economy Resource TeamBenchmarking Existing Conditions • Reducing maintenance costs Source: Wayne County Department of Public Service, 2011

  15. Economy Resource TeamBenchmarking Existing Conditions • Reducing maintenance costs 47% Reduction in mowing costs Resulting in $31,120 in annual savings

  16. Economy Resource TeamBenchmarking Existing Conditions • Green jobs • Identify jobs produced in the Southeast Michigan Green Economy (Greening of Detroit’s Workforce Development Initiatives, others?)

  17. Economy Resource TeamBenchmarking Existing Conditions • Reducing health care costs • Lower medical expenses with increased physical activity • For every $1 invested in trails, $2.94 is gained in direct medical benefits (Wang et al, 2005)

  18. Resource Team FrameworkEconomy Review • Define extent of topic area • Determine benchmarking of existing conditions • Identify goals for the topic • Define metrics used to achieve goals • Identify Targets of Opportunity for implementation • Summarize recommendations

  19. Air Resource TeamExtent of Topic Area • Particulate matter/Fugitive Dust • Energy Efficiency • Shading of buildings • Urban Heat Island Effect • Carbon Sequestration and Storage

  20. Air Resource TeamBenchmarking Existing Conditions • Particulate matter/Fugitive Dust • Identify unpaved parcels, develop metrics to run through scenarios (such as X trees/meter) to implement on these parcels to mitigate fugitive dust.

  22. Air Resource TeamBenchmarking Existing Conditions • Particulate matter/Fugitive Dust • Identify roadways of differing speed limits to help identify impacts of mitigating particulate matter along roadways.

  23. Air Resource TeamBenchmarking Existing Conditions • Energy Efficiency • Shading of Buildings • Use building footprints and tree canopy data to determine reduced energy usage of existing canopy • Average seasonal savings of 3.6 – 4.8 kWh/day (Akabari, Pomerantz, Taha, 2001) • kWh reduced * $0.0959/kWh = value of savings (Center for Neighborhood Technology, 2010)

  24. Energy EfficiencyGrosse Pointe Farms

  25. Air Resource TeamBenchmarking Existing Conditions • Energy Efficiency • Urban Heat Island Effect • Identify impervious parking lots and tree canopy to determine percentage of shaded lots • Trees lower air temperatures by 5-9o (Midwest Community Tree Guide, 2006) (Center for Neighborhood Technology, 2010) • Lower temps reduce evaporation of hydrocarbons, reduce energy usage

  26. Air Resource TeamBenchmarking Existing Conditions • Carbon Sequestration and Storage • Use land cover data and run through CityGreen to identify baseline data for carbon storage in the region
