If a lot frontage is 200 feet or less, one freestanding sign shall be permitted per building frontage and shall consist of no more than two (2) faces, said faces to be parallel, and not to exceed 100 square feet in area per sign face. If a lot frontage is greater than 200 feet, one freestanding sign shall be permitted per building frontage and shall consist of no more than two (2) faces, said faces to be parallel, and not to exceed 50 square feet per foot of lot frontage, with a maximum of 300 square feet per sign face. In lieu of the foregoing, two freestanding signs may be permitted per building provided that each such sign does not have a sign face area in excess of 150 square feet. If a lot has frontage onto more than one street, one freestanding sign shall be permitted per street frontage. The size of said freestanding signs shall be governed by the amount of street frontage as stated in this section. However, if the secondary frontage is less than the primary frontage, the maximum size of the sign on the secondary frontage shall be reduced from 100 square feet to 50 square feet if the frontage is 100 feet or less, and to 25 square feet if the frontage is less than 50 feet.
