1. Bioretention Marker

Inscription. This facility was converted from a stormwater pond into a bioretention facility in 2009. A bioretention facility, also known as a rain garden, filters polluted stormwater before it enters into a waterway.

When it rains, water washes over parking lots picking up pollutants like oil, garbage, sediment, and gasoline. Without stormwater management, this pollution would run directly into the river. At this site, the bioretention facility intercepts such pollutants before they can reach the Saint Jones River.

Erected 2009 by Delaware Department of Natural Resources and Environmental Control.
