Low Impact Development Design Strategies
Course Highlights

This online engineering PDH course describes the wide array of impact reduction and site design techniques that allow engineers and planners to create stormwater control mechanisms that function in a manner similar to that of natural control mechanisms.


The low-impact development (LID) approach combines a hydrologically functional site design with pollution prevention measures to compensate for land development impacts on hydrology and water quality. The primary goal of Low Impact Development methods is to mimic the predevelopment site hydrology by using site design techniques that store, infiltrate, evaporate, and detain runoff. Use of these techniques helps to reduce off-site runoff and ensure adequate groundwater recharge. Since every aspect of site development affects the hydrologic response of the site, LID control techniques focus mainly on site hydrology.


This 7 PDH online course is intended for civil and environmental engineers and planners as well as construction professionals who are interested in learning about low impact development design techniques and their applications.
