Resources for Low Impact Development and Green Infrastructure (LID/GI) which, among other benefits, reduces water pollution by capturing and filtering rain runoff using green roofs, permeable materials, alternative street and building design, trees and rain gardens. The Environmental Protection Agency (EPA) has found that in most cases implementing well-chosen LID practices saves money for developers, property owners, and communities while protecting and restoring water quality. It is also found that communities may experience amenities and associated economic benefits that go beyond cost savings. These include enhanced property values, improved habitat, aesthetic amenities, and improved quality of life. For these reasons, EPA is encouraging the increasing use of LID practices, including incorporating LID provisions in state issued stormwater permits (NPDES permits) which are required in large towns in cities.
