14-2H-2: ZONES:
   A.   Purpose: This section establishes the Form-Based Zones that implement the City’s Comprehensive Plan to generate and support the intended variety and physical character.
   B.   Sub-Zones: Sub-zones are slightly modified versions of the base Form- Based Zone. This chapter includes one (1) type of sub-zone:
      1.   Open: The open sub-zone can provide additional flexibility to design sites located at or near intersections that function or can function as a neighborhood node of non-residential uses. The open sub-zone is indicated in the future land use maps of the Comprehensive Plan and is used for either or both of the following purposes:
         a.   To allow more uses than the base zone allows in specific areas but within the same form and character of the base zone; and/or
         b.   To more easily allow certain uses that are already allowed in the base zone.
   C.   T3 Neighborhood Edge Zone (T3NE):
General note: The illustrations above are intended to provide a brief overview of the zone and are descriptive in nature.
      1.   Intent:
         a.   A walkable neighborhood environment of detached, small- to-large building footprint, low-intensity housing choices from house large, duplex side-by-side to cottage court, supporting and within short walking distance of neighborhood-serving retail, food and service uses.
         b.   The following are appropriate form elements in the zone:
            (1)   House-scale buildings.
            (2)   Detached buildings.
            (3)   Medium-to-large design site width.
            (4)   Small-to-large building footprint.
            (5)   Medium-to-large front setbacks.
            (6)   Medium side setbacks.
            (7)   Up to 2.5 stories.
            (8)   Porch, dooryard and stoop frontage types.
