A system and method for creating a pole support base for the installation of a road-side pole. A mounting head assembly is provided. Support legs extend from the bottom surface of the mounting head assembly and support the mounting head assembly at a predetermined height that can be selectively adjusted. Pole mounts are provided on the top surface of the mounting head assembly that enable the base of a pole to be bolted to the mounting head assembly. A hole is excavated in the place where the pole is to be erected. The mounting head assembly is placed into the hole. The legs support the mounting head assembly within the hole and enable the mounting head assembly to be adjusted for height and levelness. The hole is then filled with poured concrete until at least the legs are submersed.
