Earn 1.0 AIA/CES HSW/SD learning units by studying this article and successfully passing the online exam.
Low impact development (LID) refers to a comprehensive land planning and engineering design approach to managing stormwater runoff that emphasizes conservation and the use of on-site natural features to protect water quality. According to the nonprofit Low Impact Development Center, Beltsville, Md., the goal of LID is to “maintain and enhance the pre-development hydrologic regime of urban and developing watersheds while allowing for development or infrastructure rehabilitation.”
After reading this article, you should be able to:
