Beginning within the next 20 minutes, a casing will be hammered into the ground as part of the Bindley Expansion Project. This work should be complete between 10:15 and 10:30 am today. We do not know the amount of vibration that this will create. My apologies for the short notice - I was just notified of this activity by the contractor. Thank you for your patience, John John R.
