How Could Zoning Change in Your Neighborhood?
From single-family homes to 40-foot townhomes, mapping the transition areas and zones
One of the most highly anticipated components of the LDC revision involves the rezoning of properties along corridors, centers, and transit priority networks, as defined in Imagine Austin and the Austin Strategic Mobility Plan. These areas are seen by planners and developers as places where new housing capacity can be created to respond to market forces that have driven up land values in such desirable locations, with incremental increases in density (along what urbanists call a "transect") between existing single-family homes and these target areas. Code skeptics have worried loudly and publicly that this will effectively wipe out established neighborhoods that now lie within Austin's urban core and between high-demand centers and corridors. The LDC revision attempts to respond to both of these forces, as directed by City Council in its May 2 guidance to staff. Here's what their efforts look like in the mapping.
Transition areas are the parts of town – generally within one to three blocks of a corridor, center, or transit priority network – that are proposed to be rezoned for more missing-middle and multifamily uses.
Transition zones are the new zoning categories to be applied to all tracts in the transition areas that are currently zoned for single-family homes and duplexes, plus a scattering of other current zonings. There are two such zones: RM1 and R4, with one providing more height, more units, and more impervious cover nearer to a major corridor, and the other slightly less on lots farther away.
Corridor MappingBelow are six of the corridors with the most extensive transition zoning.
RM1: (DARK BLUE) A residential multi-unit zone. Generally, it allows 40 feet in height; 60% impervious cover; narrow lot widths for townhomes, duplexes, and live/work spaces; and up to 6 units on a 5,000-square-foot lot, or up to 10 units with participation in an Affordable Housing Bonus Program (AHBP).
R4: (LIGHT BLUE) A residential house-scale zone. It allows 4 units (8 with the AHBP bonus), 35 feet in height, 50% impervious cover, slightly narrower lot widths than in RM1, and standards intended to "maintain a house-scale aesthetic."
Single-Family/Duplex: (YELLOW) Properties outside the transition areas currently zoned SF will generally be rezoned to R2A, allowing two units per lot or, in some cases, left with their current zoning.
Other Zones: (OTHER COLORS) Properties in the transition areas zoned other than single-family/duplex residential were generally either left with their current zoning or given roughly similar new zoning.
