Track 2 Day 1: Letourneau


A Little Obsessed: Your Guide to Dominating Construction Erosion

Wednesday March 20, 2019
2:00 to 2:30 pm


Michelle Letourneau, Savanta


Erosion and sediment control (ESC) measures are pieces of the puzzle to control the movement of sediment on a construction site. Consider safety measures put in place in to protect workers in a factory, source controls are best. These are measures close to the source of the hazard and far from where harm could be caused. ESC measure installed adjacent to watercourses are on par with Personal Protective Equipment (PPE). As with PPE, proper use, fit and condition of ESC measures is essential to the measures providing the desired protection. Therefore, regular inspection of ESC measures is an important part of maintain functional ESC measures throughout the duration of the construction project. ESC measures may look good but not be performing as intended.

In this presentation I will:
• Propose a hierarchy of ESC measures;
• Provide key locations to check to assess the effectiveness of the Site ESC Plan; and,
• Use visuals to illustrate that ESC that is compromised may be hard to spot.


Learning Objectives

1. Discuss and learn a proposed hierarchy of ESC measures.

2. Learn where to look to determine if the Site ESC Plan is effective.

3. Photos will be used to develop an eye for what details of installed ESC indicate they are compromised.
