17.28 – Signs

17.28.010 – Purpose

The purpose of this Chapter is to establish a framework for a comprehensive system of sign controls governing the display, design, construction, installation and maintenance of signs that will:

  1. Balance the rights of individuals to identify their businesses and convey their messages, and the rights of the public to be protected against the unrestricted proliferation of signs.
  2. Protect the public health, safety, comfort, convenience and general welfare.
  3. Reduce traffic hazards.
  4. Enhance the attractiveness of the City.
  5. Protect property values.
  6. Promote economic development.
  7. Further the objectives of the Comprehensive Plan.
  8. Preserve the right of free speech exercised through the use of signs containing noncommercial messages.

17.28.020 – General provisions

  1. Violations
    It shall be unlawful for any person to erect, relocate, modify or alter any sign, or structure supporting a sign, in violation of the provisions of this Title. Signs which are not allowed by this Chapter as permitted signs or exempt signs shall be prohibited. No sign shall be placed on a lot without prior consent of the property owner.
  2. Placing Signs on Public Right of Way
    No signs shall be erected on any public right of way other than those placed by agencies of government or signs whose placement has been authorized by the jurisdiction having authority over the right of way. The City, without notice, may remove any sign placed on public right of way without authorization.
  3. View Obstruction
    All signs and attention getting devices shall comply with the sight triangle provisions of Section 17.22.010 F and the provisions of Section 12.04.200 of Title 12 of the St. Charles Municipal Code regarding corner obstructions, except that yard and ground signs otherwise meeting the requirements of this Chapter may be located within the sight triangle.
  4. Removal of Unused Structural Supports
    No foundation, pole, frame, cabinet, or other structural support for a sign shall be erected or maintained independently of a sign allowed by this Chapter. All such structural supports shall be removed at the time of removal of any sign or signs for which they provide support, except that a structural support may remain for a period of not more than 30 days following the issuance of a permit to change the face of a sign, or erect a different sign, using the same structural support.
(2018-Z-10: § 2)

17.28.030 – Sign area computation

  1. Area of Signs in Cabinets, Frames, and on Panels
    The area of a sign enclosed in a frame or cabinet or painted on or affixed to a panel shall be the area of the sign contained within the outer limits of the frame, cabinet or panel. The area of such sign shall not include any external architectural framing elements or supporting structure such as a post, unless the architectural elements, or supporting structure is designed as an integral part of the message or face of the sign. When there are multiple display signs within a frame, cabinet, or panel, the sign area shall be the area encompassed by the entire frame, cabinet, or panel, and not the area of the individual display signs.

  2. Area of Signs Composed of Individual Letters or Elements
    The area of a sign comprised of individual letters or other elements attached to a building wall or freestanding wall shall be the area of the smallest square or rectangle that can be drawn around the letters and/or elements.
  3. Area of Double-Faced Signs
    The sign area for a sign with two faces shall be a) when the sign faces are connected at an interior angle of sixty degrees (60) or more, the sign area shall be computed by measurement of both faces; when the sign faces are parallel or connected at an interior angle of sixty degrees (60) or less, the sign area shall be computed by the measurement of one (1) of the faces.
  4. Measurement of Sign Height Sign height shall be the vertical distance from the highest point of the sign to the grade of the adjoining street curb; if there is no adjoining curb, to the grade of the edge of the adjoining street pavement.
  5. Measurement of Sign Setback Required setbacks for freestanding signs shall be measured horizontally, from the closest point of the sign structure to the property line extended vertically.

17.28.040 – Sign standards by type

  1. Freestanding Signs
    1. The primary support of a permanent freestanding sign shall be erected in such a manner that at least forty-two (42) inches of the length of the structural support is underground. This requirement may be increased based upon the size of the sign and the height of the sign if necessary to provide for wind loads or other structural factors, as determined by the Building Commissioner. 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. The width of the base of any monument sign, as measured parallel to the sign face, shall be a minimum of fifty percent (50%) of the width of the sign face.
  2. Wall and Projecting Signs
    1. Wall and projecting signs shall be safely and securely attached to the building wall. No sign affixed to a building shall project higher than the building height.
    2. Except as permitted in the CBD-1 and CBD-2 Districts, signs shall not project into the public right-of-way.
    3. Wall signs shall be affixed flat against the building wall and shall not project more than twelve (12) inches. No wall sign shall cover wholly or partially any wall opening or architectural feature.
