    Queen Lane

    December 16, 2012 Philadelphia

    The Philadelphia Water Department installed Philadelphia's first stormwater bumpouts, or landscaped curb extensions, on Queen Lane in East Falls in 2011. Runoff from the street is diverted into the bumpouts, where it infiltrates into the soil instead of entering the city's storm sewers. In addition to managing stormwater, bumpouts can help to calm traffic and may also keep pedestrians safer by reducing the street crossing distance when they are located at crosswalks.
