3. Reduce traffic hazards.
4. Enhance the attractiveness of the City.

The Building Commissioner may require documentation from a structural engineer or manufacturer that indicates proper design and installation in relation to the sign’s structural support.
   2. Freestanding monument signs shall be mounted on a decorative masonry, metal or natural stone base. Alternative materials may be approved where they correspond with the appearance of one or more materials used on the exterior of the building.
