Resource Teams • Economy • Air • Water • Land • Overall
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
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
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)

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
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)

Economy Resource TeamBenchmarking Existing Conditions • Reducing maintenance costs Source: Wayne County Department of Public Service, 2011
Economy Resource TeamBenchmarking Existing Conditions • Reducing maintenance costs 47% Reduction in mowing costs Resulting in $31,120 in annual savings
Economy Resource TeamBenchmarking Existing Conditions • Green jobs • Identify jobs produced in the Southeast Michigan Green Economy (Greening of Detroit’s Workforce Development Initiatives, others?)
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)
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
Air Resource TeamExtent of Topic Area • Particulate matter/Fugitive Dust • Energy Efficiency • Shading of buildings • Urban Heat Island Effect • Carbon Sequestration and Storage
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.

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.
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)
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
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
