Transect Zones are the proposed new form-based zoning paradigm for much of the urban core in CodeNEXT. While current "Euclidian" zones primarily regulate the allowed *use* of buildings and secondarily regulate the building form, form-based zoning focuses regulation on the allowed size and shape of buildings and also has some (more flexible) rules governing building uses. The aim is to create more walkable neighborhoods by allowing more businesses and more dwelling units among houses, creating more destinations within walking distance. Unfortunately, many of the proposed transect zones, especially the T3 ones, do not allow enough density to support walkability.

Transect zone names follow the following convention:

 T +  [#]    +  [form descriptor]   + [optionally, setback level] + [optionally, Variation in Range of Uses]

where

  • [#] is a number that refers to the zone's land use intensity. For us, this is one of {3, 4, 5, 6}. Higher numbers are more intensive.
  • [form descriptor] : one of {NE, N, MS, U, UC}
    • NE : "Neighborhood Edge"
      • House-form
      • Generally more strictly residential, bigger setbacks
    • N : "Neighborhood"
      • House-form
      • Space between Bldgs
      • Somewhat flexible uses
    • MS: "Main Street"
      • block-form
      • maybe space between buildings, maybe not
      • Can have near-continuous frontage; adjacent to neighborhood
      • Example: Quacks in Hyde Park
    • U: "Urban"
      • Street of near continuous building frontage in mixed usage setting
    • UC: "Urban Core"
      • downtown
