Low Impact Development (LID) has several advantages over traditional stormwater management approaches. Since impervious pavement is the main source of stormwater runoff, LID strategies recommend permeable paving for hard surfaces. The course discusses LID, its goals and principles and how they are achieved. It provides an overview of permeable pavements, and more particularly, plastic permeable grid paver systems and how they support LID goals.

Upon completion of this course, the Learner should be able to:

• Discuss the need for Low Impact Development, its goals, and the environmental effects of LID Best Management Practices.
• Identify at least four benefits of sub-base water detention realized with plastic permeable grid paver systems.
• Compare various permeable pavements in terms of performance and cost.
• Use project examples to illustrate how plastic permeable grid paver systems can be used to achieve LID goals.
