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.

At the conclusion of this course, you will be able to:
•Recognize the characteristics and applicability of seven different LID methods including: bioretention (rain gardens), on-lot treatment, infiltration trenches, vegetated filter strips, green roofs, porous pavement and grassed swales.
•Explain the design considerations for the seven different LID methods
•Identify the limitations to use of each of the seven different LID methods
•Discuss the maintenance considerations for each of the seven different LID methods
•Discuss potential pollutant removal effectiveness for each of the seven different LID methods
