LID bioretention facilities that infiltrate stormwater offer new markets for landscape and nursery professionals.
This article is geared to landscape and nursery professionals. Low Impact Development (LID) landscapes can include either rain gardens or bioretention facilities. Both facilities consist of shallow depressions combining vegetation with amended or designed soils to filter and absorb water – much like a forest floor. The soil mix and vegetation enhance the infiltration, storage and removal of pollutants from stormwater. When designed properly, they hold standing water for no longer than forty eight hours after the end of a rain event with maximum ponding depths of 6-12 inches. These properties can help new and redevelopment projects meet stormwater requirements.
