At least another three or four weeks until the Dog Park can reopen. City Manager John Nachbar signed an agreement today to allow Plains Exploration & Production Co., PXP, to repair the leak on the abandoned oil well that has shut down the Dog Park since last month. “If things go smoothly,” said Mr. Nachbar, PXP will finish in a fortnight. But one further week will be needed to restore the Dog Park to its previous condition.
