RiverSmart Summer 2011
Roof runoff will flow underneath walkway into rain garden.
Extended downspout near tree will send water over river rocks into rain garden.
Beautiful new rain garden sits within existing pachysandra.
Elevated side yard is now BayScaped with plants native to the Chesapeake Bay region.
Thirsty native plants fill a deep rain garden in small front yard.
Downspout on left now sends stormwater into pervious walkway—not into shed!
Runoff in Target Neighborhoods
RiverSmart Washington will reduce runoff from hard surfaces such as alleys and driveways which now act as “chutes”, sending sheets of water into storm drains and on to Rock Creek.
Front yards in target neighborhoods vary from pocket-sized, flat, or steeply sloped. BayScaping and rain gardens will help to slow and capture rain close to where it falls.
Water runs straight along street curbs, carrying trash and pollution into storm drains at intersections. “Streetscaping” with curb bumpouts and infiltration boxes will reduce the volume of runoff. The yellow arrow in photo at far right shows location where runoff is measured in the MacFarland neighborhood.
RiverSmart Washington will install porous materials in place of impervious walkways, parking lots and parking pads. Many attractive new designs and colors are available.

Rain garden will go between blueberry bush (left) and rose bush (right).
Rain gardens are at least 12” deep to hold runoff from rooftop.
Native plants are arranged in place.
Rain garden design is careful to protect existing plants.
Public space between sidewalk and street is often neglected.
