Removal of signs. A sign shall be removed by the owner upon receipt of notice from the Township stating that the sign is unsafe or not properly maintained or otherwise does not comply with the requirements of this chapter by reason of its size, height, design, condition or location. The notice shall state that if the owner does not remove the sign, or correct the unsafe or improper condition, within a specified time period, the sign may be removed by the Township. Upon failure to remove or correct the unsafe or improper condition, the Township may take whatever action is necessary to have the sign removed or to otherwise abate the unsafe or improper condition, and in addition to other available remedies, the Township shall have the right to recover from the owner of the sign the full costs of removing and disposing of the sign or abating the unsafe or improper condition.
