As part of the Sustainable and Healthy Communities Research Program, EPA has a project to study and develop tools that will help communities make decisions that support more sustainable development patterns. One component of this project will produce tools to fill identified gaps in community needs. Not all tools identified are appropriate for the EPA to produce so we will only produce tools that are appropriate to EPA goals and expertise. This project addresses filling gaps in the suite of available community planning tools for making sustainability decisions. While planning tools help communities to visualize change and evaluate potential consequences, one identified gap is the ability to evaluate the effects of change in the built environment on local public health.
