The bioretention garden outside of Casey Trees Headquarters

Bioretention Planter

At our headquarters entrance we have installed a 1,700 square foot bioretention planter to capture up to five inches of rain in a storm.

Bioretention planters are depressions filled with soil designed to capture stormwater runoff from roads, parking lots, roofs and other surfaces. They not only filter and temporarily store water which reduces flooding – they also create favorable growing conditions for trees planted within thereby improving the site’s environmental and aesthetic characteristics.

Funding for our bioretention planter was provided by the District Department of the Environment and District Department of Transportation.
