Land disturbance associated with construction activities can leave the ground susceptible to stormwater erosion. This course covers methods to control surface runoff, sedimentation and soil erosion both during and after construction.
Although the focus is on stormwater runoff control during construction, the lessons learned from this course can be applied to any project. For each stormwater control measure, the course discusses the applicability of the measure, siting and design considerations, limitations, effectiveness, cost considerations and maintenance considerations.
The course is based on the EPA’s Best Management Practice relating to “Construction Site Storm Water Runoff Control”.
The student must take a multiple-choice quiz consisting of forty (40) questions at the end of this course to obtain PDH credits.
Specific Knowledge or Skill Obtained
This course teaches the following specific knowledge and skills:
- Land grading to reduce steep slopes and stabilize highly erodible soils
- Creating diversions where runoff from higher elevations can threaten property or worsen erosion
- Preserving natural vegetation to provide erosion control, stormwater detention, and biofiltration
- Stabilization of construction entrances
- The use of check dams for erosion control
- How to use gravel or stone filter berms for sediment control
- The applicability and limitations of grass-lined channels
- The use (and limitations) of riprap to stabilize drainageways and outlets
- Stabilization of exposed soils using chemical stabilization, mulching, permanent seeding, sodding and soil roughening
- Protection of steep slopes with geotextiles, gradient terraces, reinforced soil retaining structures, and temporary slope drainage
- How to protect waterways using temporary stream crossings and vegetated buffers
- Balancing the timing of land disturbance activities through construction sequencing
- How to minimize air and water pollution by using dust control measures
- Installation of dikes, wind and sand fences, brush barriers and silt fences to provide perimeter sediment control
