(a) Measurement Standards.
(1) Sign Area. That portion of a sign to be considered in determining its dimension shall be the area that is normally visible from any one direction. For example, a single-faced rectangular wall sign measuring four feet by six feet would have a sign area of twenty-four square feet. Free-standing signs may, however, have more than a single sign face. In such case, the maximum permitted sign face area for a single sign face shall apply to all sign faces. For example, if a sign face area of twenty-four square feet is permitted for a single sign face, a double-faced sign is permitted twenty-four square feet of sign face area for each sign face, or a total of forty-eight square feet. Frames and structural members not including advertising matter shall not be included in calculation of surface area. A logo, however, is to be considered part of the sign. The area shall be measured by the smallest square, rectangle or triangle, or any combination thereof, which will encompass the entire advertising device, including border, trim, cutout and extension.
(2) Building and Lot Frontages. Whenever the area of a sign is related to the size of the building or lot, the following shall apply:
A. The frontage of a building shall be the width of the facade of the building (excluding any roof overhang or non-bearing decorative walls) which faces the principal street or contains the main entrance. If a building is divided into units, the building unit frontage shall be the width of the unit, as measured from the party wall centerlines, on the frontage of the building.
B. The frontage of a lot not covered by a building shall be the number of linear feet the lot abuts on the principal street.
C. The maximum gross area of all permanent signs for each tenant occupying a building, or unit of a building, shall be related to the width of the building unit, adjusted, however, so that smaller establishments may be permitted reasonable sign areas and so that the large establishments may not have excessive sign areas.
(3) Temporary Window Sign Coverage. In determining the percentage of window area covered by temporary signs, each facade or side of the building shall be considered separately. Window area shall be measured to include all windows and the glass portions of doors, but shall exclude all such area covered by permanent signs or other relatively permanent material.
(4) Sign Height. The height of free-standing signs shall be measured from the base of the sign at its point of attachment to the ground to its topmost element. However, if the support of a free-standing sign is attached to a wall or other man-made base, including a graded earth mound, the sign height shall be measured from the grade of the nearest street, drive or parking area, as determined by the Building Commissioner.
(5) Sign Location. In determining the location of signs in relation to lot lines, including zoning district and street right-of-way lines, distances shall be measured from the vertical projection of the lot line, zoning district line or street right-of-way line to the closest point on the sign.
(6) Corner Lots.
A. Buildings, building units or lots with frontage on two public streets may be permitted additional signage along the secondary street, provided that such additional signage shall not exceed 20% of the area of the signage permitted along the main facade, and provided, further, that such signage shall not exceed the number of signs permitted for the principal facade and street. There shall be no greater than one building sign per street face and a maximum of two building signs per building.
B. In the case of building units within a building, an individual building unit must have direct frontage and customer entrances on both the principal street as well as the secondary street to be eligible for any additional signs under this subsection.
(b) Design Standards. Signs, as permitted in the various zoning districts, shall be designed so as to be similar in character with regard to material, color and size to signs designed or located on the same building and on adjoining buildings in order to equalize the attention they are meant to attract and to produce an overall unified effect, and in accordance with the following standards:
(1) Sign Bands Across Multiple Store Fronts. In the case of a strip center-type business building that provides an unbroken "sign band" across multiple store fronts, the Building Commissioner may, for reasons of aesthetics and balance, approve signs that may not comply with the requirement that a sign shall be set back three feet from the party wall of the business to which it pertains.
(2) The elements of the sign shall create an overall cohesive design, reflect simplicity, avoid visual clutter and ensure legibility. To that end, each sign shall:
A. Be consolidated into a minimum number of elements, whether words, symbols or graphics.
B. Have a simple shape.
C. Have appropriate contrast.
D. Be designed with a limited number of, and harmonious use of, color.
E. Be constructed with a minimum number of materials.
F. The number of items of information displayed shall be limited to ten items. An "item of information" includes a symbol, geometric shape, logo, word, abbreviation or number, or a grouping of letters or numbers which together convey meaning.
(3) Window signs shall have a clear background. A maximum of eight window signs is allowed.
(4) No part of a sign is allowed to extend above parapet, eave or gutter line.
(5) Projecting Signs. Projecting signs may be attached to the building wall or canopy and project at an angle of approximately 90 degrees for a distance of not more than three feet. Projecting signs shall be located not less than five feet from a party wall line, and the lowest member of a projecting sign shall be at least eight feet above a public sidewalk. Signs shall not project into any dedicated right-of-way or private drive.
(6) Ground Signs. Permanent ground signs shall not extend higher than seven feet above the finished grade or what is permitted within the zoning district, whichever is lower.
(7) Vertical Dimensions. The lowest member of all signs, with the exception of ground signs, which project or are supported on posts, shall be not less than eight feet above the finished grade of a sidewalk or any other pedestrian way. If located over a pavement used for vehicular traffic or within 18 inches of the vertical projection of the edges of such pavement, the lowest member of the sign shall be not less than 15 feet above the finished pavement.
(8) Relation to Windows, Doors and Emergency Means of Egress. Signs shall not project over or obstruct the required windows or doors of any building, shall not be attached to or obstruct a fire escape, and shall not interfere with other safety provisions as may be further regulated in the Building and Housing Code or the Fire Prevention Code of the City.
(9) Relation to Traffic Devices. Signs shall not be erected so as to obstruct sight lines along any public way, traffic control lights, street name signs at intersections, street sight lines or signals at railroad grade crossings. Signs visible from the sight lines along a street shall not contain an arrow or words such as "stop", "go", "slow", etc., and the movement, content, coloring or manner of illumination shall not resemble highway traffic signs.
(10) Corner Lots. No sign shall be allowed within a triangle formed between points on the front and side lot lines within 35 feet from their intersection.
(11) Changeable Copy Sign shall include mechanical and manual changeable copy. Changeable copy signs shall be permitted in industrial, public facility and business districts only and subject to the following limitations:
A. Changeable copy signs may be included as an integral part of the area of a permitted pylon or ground sign, provided that the changeable copy portion does not exceed 30% of the total sign face area of the sign. The items of permanent information shall be modified according to the following schedule:
Changeable Copy Area As a Percent Total Sign Area
Maximum Number of Permanent of Items of Information
No changeable copy:
Up to 25%:
B. All changeable copy shall comply with the lettering style, lettering color, background color and all other elements approved by the Building Commissioner but in no event display more than four lines of characters at one time with a maximum total sign text limited to ten items to allow passing motorist to read the entire copy with minimal distraction; and
C. The changeable copy or any portion of the message shall have a minimum duration of eight seconds and must be a static display. No portion of the message may flash, scroll, twirl, change color, fade in or out, or in any manner imitate movement; and
D. The changeable copy shall otherwise demonstrate compliance with all other provisions of the zoning district in which the sign is located and North Royalton Ordinance Chapter 1284; and
E. Changeable copy signs shall be permitted on the site of the use identified or advertised by the sign. No off site advertising or messages shall be displayed; and
F. Audio speakers or any form of pyrotechnics are prohibited in any sign.
