Track 2 Day 1: Williams


Putting the Green Back into Green Energy Construction

Wednesday March 20, 2019
3:30 to 4:00 pm


David Williams and Nick Emery, Stantec Consulting Ltd.


With the increased appetite for the construction of green energy infrastructure also comes an increased scrutiny on overall site design from owner, contractors, regulators and the public for these polarizing projects.

Ultimate conditions stormwater management controls are largely a vegetation management exercise involving minimizing impervious coverage and the conversion of agricultural lands to meadow grasses, resulting in an improvement of hydrologic characteristics from existing conditions for many of the sites. Often overlooked are the challenges of the interim hydrologic functionality of these sites.

This presentation highlights the variety of approaches Stantec has implemented in detailed design to mitigate potentially severe erosion and sediment control impacts of green energy construction sites. Considerations include clearcutting and topsoil stripping of entire site areas, managing external flows through the site, outlet restrictions, shallow bedrock etc., all while minimizing construction disruption.

Each project presents its own unique challenges and it is essential to consider all factors affecting design specifically for your site while also developing and implementing a robust monitoring and maintenance program.

Stantec’s erosion and sediment control designs for both solar and wind energy projects have earned many accolades from the Ministry of Environment, Conservation and Parks and have facilitated approvals for over 30 projects across Ontario.


Learning Objectives

1. Understand the many potential factors to consider when developing a SWM and ESC plan for green energy projects.

2. Present potential site-specific solutions to SWM and ESC for green energy projects.

3. Stress the importance of a robust and detailed monitoring and maintenance program.
