Purpose & background

Low Impact Development (LID), is a well-established approach now integral to numerous land development guidelines and regulations nationwide. This course will cover the fundamental principles of LID, the critical importance of water-centric site planning, and the nature-based engineered devices used and unit process in them that control runoff quantity and quality. The course will emphasize LID as a holistic approach that includes conventional stormwater management. 

Learning outcomes

Upon completion of this course, you will be able to:

  • Explain LID principles and how LID controls operate.
  • Determine if a site design development plan is water-centric using LID concepts.
  • Engage in exchanges with designers and stakeholders on high-level principles surrounding a site’s layout.
  • Explain the fundamental principles of LID and recognize the paramount role of water-centric site planning to minimize the impact of impervious surfaces on receiving waters.
  • Identify LID stormwater devices, describe their basic configurations, identify the unit processes that control water quantity and water quality, and understand their applicability.
  • Determine operation and maintenance issues for LID controls.
  • Describe the relationship between LID and conventional stormwater management and recognize that LID is a comprehensive approach that includes traditional stormwater management.
