A support device for a hollow traffic marker utilizing a base having a foot positioned at the ground surface. A boss extends from the base. A flexible sleeve positions over the outer surface of the boss, the hollow traffic marker lies within the flexible sleeve. A gap within the flexible sleeve separates the first and second spacers.

A method of forming a post sleeve within a post hole in the ground to include a post receiving cavity to insertably receive and support a post is provided. The method includes positioning a post sleeve core within the post hole with the aid of an elongate installation member and depositing uncured material into the post hole to at least partially surround the post sleeve core while the post sleeve core is attached to the elongate installation member. The method further includes allowing the uncured material to harden around the post sleeve core to form at least a portion of the post-receiving cavity of the post sleeve and removing the post sleeve core from the hardened material to expose the post receiving cavity to receive and support the post. Other related methods of forming post sleeves are also provided.

A mount for a charging station comprising a precast concrete base. The precast concrete base has a bottom surface, a top surface, and a base height. The base height is the distance from the bottom surface to the top surface. The mount further comprises a through hole extending from the bottom surface to the top surface. The through hole is centrally located on the precast concrete base. The mount further comprises a plurality a plurality of non-through holes extending upward from the bottom surface toward the top surface. Each of the plurality of non-through holes has a depth that is less than the base height. Each of the plurality of non-through holes is adapted and configured to enable a user to increase the depth of each of the non-through holes to convert the plurality of non-through holes to a plurality of bollard mounting holes.
