1127.10 ERECTION AND STRUCTURAL REQUIREMENTS.
   (a)    Loads, Allowable Stresses and Materials for all Signs. 
      (1)    All signs and supporting structures shall be of sufficient strength and bracing to withstand wind pressures of thirty pounds per square foot of surface exposed. The exposed area subjected to wind pressure shall be the total area of all parts of the sign including structural framing on a plane perpendicular to the direction of the wind. In determining the stress in any member the wind shall be assumed to flow from the horizontal direction and from that compass direction which produces the maximum stress in that member.
      (2)    In all signs, the allowable stresses, materials and details of design shall render all signs safe to persons, property and traffic along all streets, public thoroughfares and publicly traveled areas. All signs shall be designed, constructed and installed in conformity with the provisions of this chapter, Part Thirteen of the Building Code and applicable statutes of the State.
      (3)    All signs shall be supported by sign structures which are made of steel or other metal, concrete or wood and designed and constructed to resist wind pressures, dead loads and lateral loads in accordance with the following specifications:
         A.    For steel sign structures - American Standard Building Code requirements for structural steel as approved by the American Standards Association.
            Secondary members in contact with or directly supporting the facing may in all types of signs be formed of light gauge steel, provided such members are designed in accordance with the Light Gauge Steel Design Manual of the American Iron and Steel Institute.
         B.    For wood sign support structures - National Design Specifications for stress grade lumber and its fastenings, recommended by the National Lumber Manufacturers Association.
         C.    The working stresses of chains, cables, wire ropes and steel rods and their fastenings shall not exceed one-fourth of their ultimate strength.
      (4)    Signs may be constructed of steel or equivalent metal, industry approved plastics, wood or combination thereof, except illuminated exterior signs shall be constructed entirely of metal and noncombustible materials. Faces may be made of an approved combustible plastic provided the remainder of the sign and structure is noncombustible.
   (b)    Metal Parts. All metal parts used in any sign or structure, supports and braces, shall be of corrosion-resistant material, or shall be galvanized and/or painted with approved corrosive-resistant paint at least once every two years. When existing poles or structures are used for new or remodeled sign installation, all remaining parts must be brought to like-new condition, and painted with approved rust and corrosion-resistant paint. Existing pole or sign supports must be approved before being used in new or remodeled sign installation.
   (c)    Electrical Wiring. All electrical wiring, fittings and component parts used in the construction, connection and operation of an electrically illuminated sign shall be in conformance with the National Electrical Code.
      (1)    There shall be a disconnect switch on all roof signs at the sign.
      (2)    There shall be a lock-type switch on all signs.
   (d)    Name of Sign Company. All signs hereafter erected, altered or relocated, shall be plainly marked with the name of the person, firm or corporation erecting, altering or relocating such signs.
   (e)    Obstructing Fire Escape. No sign of any description shall be installed, erected or constructed in such a manner as to obstruct any fire escape or any door or window giving access to any fire escape, nor shall any sign be attached in any form, shape or manner to a fire escape.
   (f)    Obstructing Window. No flat wall sign above the first floor, projecting sign or marquee sign or their supports shall be situated to cover any window or part of a window or obstruct the light or vision of a window.
   (g)    Maximum Height and Weight. No free-standing sign shall have a height greater than thirty feet; no roof signs shall be erected and no projecting or marquee sign shall have a weight greater than 1,000 pounds per section unless an application is accompanied with complete drawings and specifications bearing the seal of an Ohio licensed engineer or architect.
   (h)    Attachment to Wall. Every permitted sign shall be securely attached to the building walls, marquees or structure, suitable metal poles or supports, by iron or metal anchors, bolts, supports, chains, stranded cables, steel rods or braces.
   (i)    Wall Signs. Wall signs attached to exterior walls of solid masonry or concrete shall be safely and securely attached to the same by metal anchors, bolts or lead expansion anchors of not less than three-eights of an inch in diameter and shall be imbedded to the manufacturer's required depth for the device used.
      (1)    No wooden blocks or anchorage with wood used in connection with screws, nails, spikes or staples shall be considered proper anchorage.
      (2)    Wall signs attached to wood walls may be supported by lag screws of not less than one-fourth of an inch in diameter, but must be of a size and length to support the load involved.
   (j)    Roof Signs. No roof sign shall be placed upon the roof of any building so that it will project beyond the edge of such roof in any direction nor setback less than four feet from the face of any front or rear wall.
      (1)    No sign shall be placed on top of any parapet wall or corner so that it interferes in any way with the free and easy passage to the roof.
      (2)    All roof signs shall be constructed so as to leave a clear space of not less than three feet between the roof surface and the lowest part of the sign structure and at least five feet clearance between the vertical supports thereof.
      (3)    Roof sign supports, uprights and braces shall be constructed of noncombustible materials.
      (4)    Every roof sign shall be thoroughly secured to the building by steel or other metal anchors, bolts, supports, rods or braces. When erected on buildings which are not constructed entirely of fireproof material, the bearing plates of the sign shall be fastened or attached directly upon the masonry walls and intermediate steel columns in the building or structure. No roof sign shall be supported or anchored to a wooden framework of a building or other structure.
 
   (k)    Free-Standing Signs. 
      (1)    All parts of a free-standing sign shall set back no less than five feet from the front property line. The sign face shall be no less than nine feet above the surface of the ground if parking or pedestrian traffic is permitted beneath the sign or adjacent to the sign. No such signs shall be supported or braced from utility poles, City property, sidewalks, streets or street right of way. (Ord. 128-74. Passed 11-5-74.)
      (2)    Pole sizes, structural supports and foundations shall be of sufficient strength to support the sign and withstand all imposed loads as required by the latest edition of the Ohio Building Code.
      (3)    No foundation is to be poured and no sign erected until the excavation for foundation or foundations has been inspected by the Building Inspector.
      (4)    Free-standing signs shall be designed and constructed in accordance with the latest edition of the Ohio Building Code.
 
   (l)    Signs Located Near Overhead Conductors. Signs shall be located not less than six feet horizontally or twelve feet vertically from overhead electrical conductors which are energized in excess of 750 volts. The term "overhead conductor" means any electrical conductor, either bare or insulated, installed above the ground, except such conductors as are enclosed in iron pipe or other material covering of equal strength.
