Site Development

Low Impact Development (LID) is a voluntary approach to stormwater management that can benefit both the economy and the environment by reducing infrastructure costs, increasing lot yields and enhancing water quality protection.

The Definition of LID

A development is considered LID when the volume of runoff leaving the site after development matches the volume of runoff before development. In addition, the  LID project should maintain adequate flows to the streams and wetlands on the site rather than piping stormwater to a single low point.
