Several innovative design alternatives such as bioretention, on-lot treatment, porous pavement and green roofs have been developed in an effort to help combat the significant stormwater problems produced by traditional development methods. A number of these methods fall into the category “Low Impact Development (LID)” which focuses on water resource and natural resource protection.
This 3-hour interactive online course describes a number of the LID methods that have been proposed. It includes information on applicability, design considerations, limitations, maintenance considerations and pollutant removal effectiveness of these methods. The course is based on guidance provided by the US EPA.
