If you plan to build, remodel, plant a tree, or any project that requires digging, simply dial 811 to request underground utility locates. This special service, Iowa One Call, notifies all the necessary utilities before you dig, which helps you avoid potential injury or even death. Just call 811 at least 48 hours before you plan to dig. We will locate and mark the city owned buried lines in your yard free of charge.
