Each zone is controlled by an electric valve and the valve for that zone is stuck open. It will likely need to be replaced. The house water and irrigation water are separate and there should be two separate valves in the front yard. You should be able to open the covers for those and turn them each off to see which is the irrigation valve (it should have purple colored piping going from the valve towards the house, denoting it is non-potable water). Just leave that one off until a repair person can come out.
