When do I need Iowa One Call (IOC)?

Contact IOC anytime you plan to excavate. Whether it’s a small or a large construction or homeowner project (such as putting up a fence or clothes line, planting trees or shrubbery, landscaping, building a home addition, deck, foundation, or replacing a driveway or sidewalk, etc.) you must submit a locate request at least 48 hours (not counting weekends and/or legal holidays) prior to excavation. IOC will notify the owners/operators of underground facilities who are IOC members and who have facilities in the area of planned excavation, of this planned excavation activity.
