Beacon Institute Bioretention Basin


Bioretention basin at the Beacon Institute

This bioretention basin is an example of green infrastructure in an institutional setting. It protects the water quality of the Hudson River by capturing and filtering stormwater runoff from the building and site. The retained runoff allows heavier sediments to fall to the bottom of the basin where it is filtered by plants, natural decomposition, and evapotranspiration. Further filtering takes place as the runoff slowly seeps through the underlying soils before reaching groundwater. The location chosen was a naturally occurring basin in the existing landscape, maintaining the project's low-impact footprint. In addition, the plants in and around the basin are native to this area, have excellent filtering capabilities, and attract birds, butterflies and wildlife.
