An Introduction to Low Impact Development

COURSE NO: C04-016
An Introduction to Low Impact Development
Course Highlights

This online engineering PDH course will present the basic concepts of Low Impact Development (LID); a stormwater management strategy concerned with maintaining or restoring the natural hydrologic functions of a site to achieve natural resource protection objectives and fulfill environmental regulatory requirements. You will learn about stormwater management using the hydrologic cycle approach, LID design goals and objectives, a comparison of LID to conventional stormwater management practices, and how distributed micro-scale systems are used in LID.


This 4 PDH online course is intended for engineers and construction professionals who are interested in gaining an understanding of the basic principles of LID that will allow them to apply LID strategies when addressing regulatory and environmental requirements associated with land development projects.
