Description:

Erosion control can be a challenge even on an easy site, but protecting Low Impact Development (LID) practices, which are designed to infiltrate or filter stormwater for more than 30 years, requires an ESC plan on steroids. The secret to success starts with an effective design that is communicated through a plan set and specifications that clearly define what will be required during construction and throughout the life of the LID practice. Once construction starts, communication and adaptability are the keys to meeting the unique needs of that development during mass grading, street and utility installation, building construction, final excavation and construction of the practice. For some practices it ends there, but for most LID’s we must more thoroughly address construction sequencing, performance testing, vegetation establishment and maintenance, and long term operations and maintenance for years to come.

This course will focus on understanding the difference between traditional stormwater practices and LID practices in new development from mass grading to final stabilization and certification, as well as retrofit projects from subwatershed analysis through concept development and final installation. We will also develop ESC plans for successfully installed new development and retrofit.

Learning Objectives:

Attendees of this class will be able to:

1. Differentiate between erosion control and sediment control.
2. Recognize which erosion and sediment controls work best in new and redevelopment scenarios.
3. Distinguish between traditional stormwater and Low Impact Development stormwater approaches.
4. Recall good LID basin practice design concepts.
5. Reproduce good installation specifications for LID basin practices.
6. Describe the process for developing an ESC plan for new development from mass grading through final stabilization.
7. Summarize how to identify and plan retrofit projects from initial analysis to final stabilization.
8. Recognize good LID plans and specifications.
