4.2.7 Specific Standards
- For lots of one acre or more in area, a minimum of 10% of total contiguous area under single ownership or control is encouraged to be devoted to accessible open space, such as squares, greens, or greenways, located at high-use portions of the site. This open space should be framed by building facades where possible and should comply with the standards of the D-OS and/or D-OG zone. In lieu of site-by-site compliance, property owners of contiguous lots within the same zone may provide this accessible open space on an aggregate basis, so long as the total area of the space is equal to or greater than the combined minimum required area of accessible open space for each individual lot and the space is within 1,320 feet of sites served.
- All principal buildings, with the exception of those located more than 200 feet from a public thoroughfare, must be oriented to the thoroughfares onto which they face, with front and corner facades positioned parallel or radial to adjacent right-of-way lines.
- The following exterior facade materials are restricted on principal buildings:
- Exterior insulating finishing systems (EIFS) are prohibited on the ground story of front and corner side facades, and are limited to 20% on upper stories of front and corner side facades.
- Standard, fluted, or split face concrete masonry units (CMUs) are prohibited above the basement level on front and corner side facades. Glazed or heavily polished CMUs are allowed.
- Vinyl siding is prohibited.
- Reflective wall surface material with a Visible Light Reflectance (VLR) of greater than 15% is prohibited.
