Dial before you dig.
Planting shrubs in early fall gives the plants a head start at establishing roots in the season's cool, moist soil. Perhaps you’re planning to build a new deck to enjoy those cool autumn evenings. If any of your fall projects require digging––such as planting trees or shrubs, or setting posts––remember to dial 811 first.
Underground utilities, such as buried gas, water and electric lines, can be a shovel thrust away from turning a fall project into a disaster. Play it safe by dialing 811 to find out where utility lines run on your property. Your call will be routed to a local “one call” center. Tell the operator where you're planning to dig and what type of work you will be doing, and affected local utilities will be notified.
In a few days, a locator will arrive to designate the approximate location of any underground lines, pipes and cables. These areas will be marked with flags or paint so you'll know what's below. Then the safe digging can begin.
Also, when planting trees, keep the tree’s growth potential in mind to ensure that it will not encroach the power line right-of-way.
