Office workers and others shut out of McPherson Square by Occupy DC since October will be barred from the park’s south lawns until at least September after the National Park Service shut off part of the square Monday to begin reseeding the lawn destroyed by Occupy’s tent city.

The Park Service began repairing the south end of the park at a cost of about $6,000, said Karen Cucurullo, deputy superintendent for operations, though the service originally estimated it would cost just $8,000 to place new sod across the entire park.
