Construction continues on the Alliance for the Chesapeake Bay’s Greening Virginia’s Capitol project at Capitol Square in Richmond, Va., on June 7, 2011. Richmond is “going green” by retrofitting city streets and the grounds of Capitol Square, implementing porous brick pavers and rainwater harvesting to reduce polluted stormwater runoff.
