A. Purpose. To preserve the character of designated historic properties and surrounding neighborhoods, an integrated design approach shall be taken when elevating Sullivan's Island Landmarks and Traditional Island Resources.
B. Design Standards. Any proposed elevation or site relocation of an historic structure shall carefully consider site conditions (site elevations and topography), parcel access, typology of architecture, building composition and scale, and its context with adjoining historic properties while employing the following standards:
(1) Height: To minimize the height of elevating historic structures, the finished floor elevation (FFE) shall exceed no more than three (3) feet above finished grade.
(2) Composition and Scale: To maintain an historic building's visual character and design compatibility with the surrounding neighborhood, an elevation design plan shall be submitted to illustrate the composition and scale of the building's principal architectural features are being maintained and will remain proportional to the elevated foundation.
(3) Perspective and Orientation: Any proposed elevation or relocation should maintain the building's historic perspective from the principal right-of-way. All historic architectural elements should be maintained after elevation or relocation.
(4) Scale Minimization and Architectural Screening: Appropriate measures should be introduced into the site design to reduce or eliminate negative visual effects from the elevation of a historic structure. These elements include fencing, landscaping (foundation plantings), stair configuration and any other site considerations noted by the Design Review Board.
C. Design Review Board. Design Review Board may on a case-by-case basis, increase the height of a historic structure by up to two (2) feet above the standard set forth in Section 21-44 B. (1) and make other determinations of the above design criteria to achieve greater neighborhood compatibility and to achieve the goals and standards of the Historic Preservation Overlay District (Article XI).
