During an expansion of Aqua America’s Bryn Mawr headquarters in 2005, Lower Merion Township’s Environmental Advisory Council recommended the addition of bioretention areas to the site’s parking lot to help alleviate the overflow of runoff into Lancaster Avenue. Parking lot islands near the entrance were planted with native vegetation to capture runoff from the parking lot, which helps to filter sediment and other pollutants from runoff. Additionally, the bioretention areas increase the site’s capacity to infiltrate runoff to promote groundwater recharge.
