## Sign plan & submission notes

- Special conditions within large-scale developments may be addressed through a "planned signing program" (also called a planned signing program or common sign plan) intended to provide flexibility while meeting Chapter 410 objectives (Section 410.095(A)).
- A planned signing program application must be processed in conjunction with a PD/PUD area plan or amended area plan, following the PD/PUD procedures in Chapter 400, Article V (Section 410.095(A)(1)).
- A planned signing program must include and provide for all signs within the development boundaries; no sign within the development is permitted unless it is part of the approved planned signing program (Section 410.095(A)(2)(a)).
- All signage under a planned signing program must share common design and materials and be crafted specifically for that development, must not be located in rights-of-way, must comply with intersection visibility standards, must comply with the prohibited-signs article, and must meet safety and maintenance requirements (Section 410.095(A)(2)(b)-(f)).
- If a planned signing program is denied, individual sign permits may be applied for and processed under otherwise applicable standards (Section 410.095(A)(4)).
- Multiple-building, multiple-tenant developments may use a "common sign package" consisting of: (a) external development signage (primary and secondary freestanding signs based on frontage); and (b) internal outlot signage (one small freestanding sign per lot, with slightly larger signs for multi-tenant buildings) (Section 410.090(A)(6)).
- In MUTDD, HTCD and other specially designated mixed-activity or community-style areas, owners may seek additional internal "community" signage upon approval of a conditional use permit by the Planning and Zoning Commission; the size, height, configuration, design and number of such signs are reviewed and approved as part of the CUP (Section 410.090(A)(5)).
- For interchange signs and other special use signs, a sign permit application must include scaled drawings or renderings prepared by a licensed or registered professional showing sign size in relation to surrounding structures and topography (Section 410.090(A)(1)(e)).
- All multiple-tenant developments containing two or more buildings on separate lots can create a comprehensive sign package, which functions as a coordinated sign plan, combining external development signage and internal outlot signs (Section 410.090(A)(6)).
- All applications for sign permits (including those under sign plans, planned signing programs, and common sign packages) must be electronically submitted with a scaled plot plan or building elevation, sign configuration details, and structural information as specified in Section 410.100(A)(1).
- Variances, interpretations and appeals from the sign regulations, including for any sign plan, must follow the general procedures set out in the O’Fallon Zoning Code, and a variance requires a showing of exceptional circumstances that prevent practical use of the property under strict application of the regulations (Section 410.160(A)-(1)).
