Subsurface Gravel Wetland and Bioretention System Design
Subsurface Gravel Wetland and Bioretention Design Workshop
The subsurface gravel wetland is a recent innovation in Low Impact Development (LID) stormwater design. It approximates the look and function of a natural wetland, effectively removing sediments and other pollutants commonly found in runoff, while enhancing the visual appeal of the landscape and adding buffers or greenscape to urban areas.
Bioretention systems, also known as “raingardens,” are among the most common Low Impact Development (LID) stormwater approaches in use today. These systems consist of landscaped depressions which collect runoff that subsequently ponds, filters through a soil mix, and infiltrates into the ground, or discharges to the surface.
This workshop provides stormwater management professionals with the most up to date characteristics of successful subsurface gravel wetland and bioretention system designs and installations. This full-day training includes field visits to a variety of on-the ground installations throughout the UNH campus and the town of Durham. Participants will learn key design principles necessary to successfully design, evaluate, specify, and install subsurface gravel wetland and bioretention systems for stormwater management.
Where are the workshops?
The workshops will begin at the UNHSC field facility located in the Western corner of the West Edge Parking Lot. The UNH campus map may be found at: http://www.unh.edu/transportation/visitor/map.pdf The field facility at the West End Parking lot is the blue-colored lot on the upper left hand corner of the map.
