Stop Sprawl
Healthy Growth Calculator

See the table below for your results. In the left column, you will find the impacts of typical sprawl density: costs of driving, how much water is available, what shopping is like, etc. In the right, you will see the impacts of your own choice.

For details about the impact and how it is calculated, click on the section heading, use the left navigation, or follow the "more info" links at the bottom. Numbers rounded and are developed using data for, and applies to, census tract sized neighborhoods (1,000 – 6,000 Hh) in metropolitan areas, not to isolated developments or rural towns.
