Fact Sheet: Infiltration Trenches and Dry Wells

Posted on November 1, 2010 at 12:08 pm. Written by Kit Un

Infiltration trenches and dry wells are standard stormwater management structures that can play an important role in Low Impact Development site design. Dispersed around the site, these infiltration structures can […]

Fact Sheet: Low Impact Site Design

Posted on November 1, 2010 at 12:01 pm. Written by Kit Un

Conventional development strategies treat stormwater as a secondary component of site design, usually managed with “pipe-and-pond” systems that collect rainwater and discharge it off site. In contrast, Low Impact Development […]

Fact Sheet: Vegetated Swales

Posted on October 27, 2010 at 3:18 pm. Written by Kit Un

Vegetated swales are an important Low Impact Development technique used to convey stormwater runoff. These open, shallow channels slow runoff, filter it, and promote infiltration into the ground; as a […]
