The sustainable suburb scenario

Population density	Vehicle miles traveled	Greenhouse gas emissions	Park space	Water quality
Environmental
A minimum of 2,500 people per square mile	Low to medium. Under 10,000 miles per year. Increased use of electric vehicles.	Low	10 acres or more per 1,000 residents	Good quality. Little stormwater runoff with use of green infrastructure.

Housing	Transportation	Health	Park space	Beauty
Social
More multi-family housing	More walking, biking, and transit. Less driving.	Better air quality, More physical activity in walking and biking.	Within a ten-minute walk of a park.	Nature and green infrastructure.

Housing	Infrastructure	Health	Jobs	Overall cost
Economic
End exclusionary zoning. Greater mix of housing types and affordability of housing. Energy efficient buildings.	Fewer roads and utilities. Renewable energy.	Lower health costs with less commuting and more physical activity.	More people working from home. Lower com-muting costs.	Lower housing, transportation, infrastructure, and health costs. Savings from greater climate resilience.
