Big-box stores have significant impacts on a community’s economy, environment, and character. The Big Box Evaluator (created by the Orton Family Foundation, which offers numerous programs that aid good land-use planning) is a new online tool designed to help citizens, activists, and municipal officials get the basics on these impacts in an unbiased manner.

It’s interactive, and lets you plug in variables like tax rates, community demographics, size of a hypothetical big-box proposal, and much more. The outcome is a well-rounded assessment of probable impacts, the good as well as the bad, which will help its users ask important questions when proposals like this come to town.
