The Village of Roselle recommends the flags be installed between the sidewalk and house on private property. For uniformity, flags will be installed approximately ten feet from the sidewalk. They will be secured by a ½-inch metal support that will go into the ground, at a 70-degree angle, between 10 and 12 inches. The Village also recommends that, prior to installation, residents contact J.U.L.I.E. at 1-800-892-0123 or at 811, to avoid possible interference with any underground utilities.
