The business owner, property owner, and/or sign contractor shall submit photographs and/or a rendering of the affected building and details of the proposed sign, including design, size, location, materials and color, to the Community Development Department for review and approval by the Downtown Architectural Review Board prior to the issuance of a building permit as may be required by this section. Certain minor actions that do not affect the character of the Downtown Design Overlay District may be approved by the Community Development Department, such as the repair, modification or replacement of an approved sign. Community Development staff shall determine if a structure and/or site is of historic or architectural significance, and if so, whether requirements of Chapter 374, Historic Preservation, apply. Where a property is a City-designated historic site or structure, the Historic Preservation Commission shall review new signage and, if compatible, approve; review by the Downtown Architectural Review Board is not required.
