I'm looking for examples of two-story minimums in form-based zoning codes (particularly TOD zoning codes). Although two-story minimums may be implemented in mixed use districts to encourage higher density, they can also create some difficulties, such as:
-Some civic uses, such as churches and theaters, may need the height, but not the dual stories.
-Small size; a structure may not be big enough to support two stories.
-Topography may preclude two-stories.
The main questions I'm interested in answering are:
1. How does one define a "two-story building" or a "story" in general? (Do churches with choir lofts or theaters with balconies count as two-story buildings?)
2. How can one build in flexibility to codes that include a two-story minimum? Are there precedents for procedural or other ways to adjust this requirement when necessary?
