Rain barrels can reduce stormwater runoff from your property while providing water you can use for irrigating landscaped beds, watering potted plants, or outdoor chores like bike or car washing. In collaboration with the City of Charlottesville, the Rivanna Stormwater Education Partnership, the Albemarle County Service Authority, and the James River Association, the Piedmont Master Gardeners will participate in a workshop on how to set up your own rain barrel at 6 p.m. May 11 at Pen Park Shelter 2. Registration opens at 10 a.m. April 24. For the registration fee, you will receive a plastic barrel and a DIY assembly kit.
