Raising the Bar: Green Stormwater Infrastructure Planning and Design Workshop – 2014

Please join us for a two-day intensive workshop focused on the use of green stormwater infrastructure (GSI) systems and practices to achieve stormwater management goals.

Stormwater runoff, caused by precipitation running off impervious surfaces and developed lands, is a leading cause of surface water pollution. Managing the quality and quantity of this runoff is of utmost importance for the health of our communities and the protection of natural resources.

The workshop will include an overview of why and how the national stormwater world is shifting to place more focus on volume reduction, small-scale practices close to the source of runoff, and green practices that utilize soils, vegetation, and natural processes to reduce the volume of and remove pollutants from stormwater. Presentations on green stormwater design practices and principles will be included, as well as a hands-on site design charette using real-world site plans from Vermont. This charette will give participants experience with applying green practices to sites that utilized more traditional approaches, but where there were missed opportunities to apply green practices. The workshop will also include a session on implementation strategies and challenges for Vermont.

Continuing education credits for both planners and landscape architects are anticipated.
