CITY OF CAMBRIDGE: A STAR COMMUNITY
3
7 GOALS, 44 OBJECTIVES, 500+ METRICS
4
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 walls b)Water management through wetlands, stream buffers, permeable surfaces c)Recreation through parks and greenways 2.Demonstrate that 85% of population lives within.5 mi walk from green infrastructure.
5
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.
6
Identify where people live: residential units Identify park entrances
7
TOTAL: 100% POPULATION Calculate.5 mi walk from park entrances: Run network analysis
8
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
9
CCC OUTCOMES: DENSITY, DESTINATIONS, ACCESS 1.Diverse Uses: > 7 diverse uses present 2.Walkability a)Intersection Density: > 90/sq mi b)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 line b)80% of building setbacks on commercial blocks <10 ft. from property line
10
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 USES 20+ USES IN EACH CCC
11
Intersection Density: >90 intersections/sq mi. Earned bonus points for having 176-419 intersections/sq mi WALKABILITY
12
Sidewalks: >90% roadways have sidewalks on both sides Earned full points in each CCC WALKABILITY
13
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
14
110-174 JOBS/ACRE Calculate land area used for employment in each CCC Use 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
15
Residential setbacks: >80% of buildings are <25 ft. from property line: full points Commercial setbacks: 80% of buildings <10 ft. from property line DESIGN
16
Commercial setbacks: 80% of buildings <10 ft. from property line: No points in Harvard or Kendall/MIT CCCs DESIGN
17
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
18
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.
