Leaves blanket the grass at 42nd Street and Stonewall Avenue in South Side — a familiar autumn scene in many areas of Richmond. Rake and blower time has arrived. In a move to save money, the city has pushed back its leaf collection and will limit it to one pass. The start date: Monday, Nov. 30. The collections will begin in neighborhoods in the North Side, adjacent to Downtown and in the near West End and continue across the city through early February. The work will be delayed if there are snowfalls.
