Mapping Sustainable Wellbeing
Erin CouttsGlobal Development And Environment Institute,Tufts University
City of Cambridge: A STAR Community
7 Goals, 44 Objectives, 500+ Metrics
Green Infrastructure
1. Demonstrate 35% of land area has protected vegetated surfaces performing a minimum of 2 of the following functions:a) Localized cooling through tree canopy, green
roofs, green wallsb) Water management through wetlands, stream
buffers, permeable surfacesc) Recreation through parks and greenways
2. Demonstrate that 85% of population lives within .5 mi walk from green infrastructure.
Total:38% Coverage
Calculate total land area in jurisdiction: Remove area covered in water
Calculate vegetative land area: Union canopy & open space, identify canopy over open space, calculate total canopy, calculate open space not covered in canopy.
Identify where people live: residential units
Identify park entrances
Total:100% population
Calculate .5 mi walk from park entrances:Run network analysis
Compact & Complete Communities Identify 4 land areas a .5 mi walk from a central point with the strongest mix of uses, transit availability, density, and walkability
CCC Outcomes:Density, Destinations, Access
1. Diverse Uses: > 7 diverse uses present
2. Walkabilitya) Intersection Density: > 90/sq mib) Sidewalks: >90% roadways have sidewalks
3. Residential Density: >12 dwelling units/acre
4. Employment Density: >25 jobs/acre
5. Design: a) 80% of building setbacks on residential blocks <25 ft. from
property lineb) 80% of building setbacks on commercial blocks <10 ft. from
property line
Food Retail: Supermarket, Grocery with produce section
Community-Serving Retail: Convenience store, hardware, pharmacy
Services: Bank, gym, laundry, restaurant
Civic & Community Facilities: Medical clinic, museum, place of worship
Diverse Uses20+ uses in each CCC
Intersection Density:>90 intersections/sq mi. Earned bonus points for having 176-419 intersections/sq mi
Walkability
Sidewalks: >90% roadways have sidewalks on both sides
Earned full points in each CCC
Walkability
units/acre:27-104
Identify residential parcels without transit access: All residential parcels in CCCs are within .5 mi of T stop or .25 mi of bus stop
Calculate dwelling units/acre for each CCC:Exclude residential parcels <50% in CCC. Divide remaining number of dwelling units by the area of land used for residential purposes.
Residential Density
110-174 jobs/acre
Calculate land area used for employment in each CCCUse only parcels >50% in CCC and designated for commercial land use
Calculate jobs/acre for each CCC:Use Journey to Work for data on total workers by TAZs. Divide # jobs by area of land used for employment purposes.
Employment Density
Residential setbacks: >80% of buildings are <25 ft. from property line: full points
Commercial setbacks:80% of buildings <10 ft. from property line
Design
Commercial setbacks:80% of buildings <10 ft. from property line:
No points in Harvard or Kendall/MIT CCCs
Design
Next Step: Equitable Access
Demonstrate increased access and proximity by residents of diverse income levels and race/ethnicity to the following community facilities, services, and infrastructure:
1. Public transit facilities and service levels 2. Public libraries 3. Public schools 4. Public spaces 5. Healthful food 6. Health and human services 7. Digital access or high speed internet 8. Urban tree canopy 9. Emergency response times
Recommendations
1. Consider contributing to STAR’s technical guide
2. Talk to STAR about which communities in your area are certifying. Suggest that your students consider interning with those communities.
