Have you seen one of DEP’s new green street rain gardens?
In 2012, DEP installed 46 rain gardens along roadways and parking lots at Forest Estates, White Oak, Dennis Avenue, Arcola Avenue, Aspen Hill Library, and Kensington Library. These rain gardens and other vegetated improvements were installed to reduce and filter rainfall and pollutants that wash off surface areas (stormwater runoff). Rain gardens like these help to keep our local streams and rivers healthy.
To keep these rain gardens looking good and functioning well, DEP hired a maintenance contractor to visit the sites monthly. So, if you see a couple people working around the rain gardens, they are:
DEP’s contractor completed winter pruning of the plants during their monthly maintenance in March. In May, we are replenishing mulch to a 3” depth to help prevent invasive weeds. It is important to do this routine maintenance regularly to make sure the rain gardens continue to filter stormwater from roads, parking lots, driveways, and roofs.
Thanks to all the neighbors who live along our Green Streets who have been helping us pick up trash and carefully mow grass along the edges of the stormwater facilities. With spring pruning done and the weather warmer, you should keep an eye out for these to turn green and spring back to life over the next few weeks!
