Course Title: New York Erosion and Sediment Control

Delivery Method: Live Online

Course Description: This course examines erosion and sediment control requirements and practices, goals and selection of erosion and sediment control practices, non-structural and structural control practices, stream and bank stabilization techniques, and sediment traps and sediment basins, with particular attention paid to site conditions in New York state.

Learning Objectives:

Learning Objective 1:
Learners will be able to utilize practices that minimize project site disturbances that cause erosion and preserve native vegetation.

Learning Objective 2:
Learners will be able to control erosion and control sedimentation on construction sites with structural best practices, including earthen dikes, pipe drains, silt fences, check dams, drainage swales, subsurface drains, and berms.

Learning Objective 3:
Learners will be able to comply with federal Environmental Protection Agency and New York erosion and sediment control requirements.

Learning Objective 4:
Learners will be able to control site disturbances with the use of non-structural best practices, including temporary and permanent seeding, sodding, mulching use of geotextiles, chemical soil stabilization, and buffer zones.

Learning Objective 5:
Learners will be able to establish practices to protect stream banks from erosion and be able to explain how to stabilize and repair damaged stream banks.

Learning Objective 6:
Learners will be able to discuss permanent stormwater management practices by understanding the basics of hydrology, rate versus volume control, and using ponds, infiltration practices, and bioretention.
