RE: UDC Update
SUBJECT: Chapter 3
38.320.030 Table of Form & Intensity Standards
Residential Districts
Minimum Lot Width (pg. 197)
Greetings -
I am writing this letter to ask that, as part of the current UDC update and review, you
consider revising the attached table relating to minimum residential lot widths.
The current and proposed code allows lot widths of 30’ in all residential zoning districts,
but only if project will meet affordability standards. See Attachment A.
I would ask for consideration for lots, in R3 (medium density) and R4 (high density)
districts, to ALSO be allowed to be a minimum of 30’ in width, when adjacent to an
alley, regardless of how much the home costs.
This is not a density change issue, and other sections of the code ensure minimum lot
area, setbacks, lot coverage, height and uses for orderly development. Historically, lots
varied in width, and many examples exist around town where modest homes exist on
smaller lots, which is a characteristic we strive for in many parts of the existing code. I
believe this proposed change would result in quality infill where unique conditions exist
around the city and produce models to emulate going forward.
In short, the value of a project should not dictate zoning (lot width).

Thank you for your careful considerations,

Attachment B: Housing site scenarios
A comparison of the housing options of a 75’ wide lot (R3) illustrates how mass, scale
and density are affected by the code, and a traditional neighborhood development
pattern (smaller building foot prints) could be prohibited, while favoring larger buildings.
Small Homes / Garages
Separate Lots (32’w & 43’w)
Only if Affordable Standards Met
Large House / Garage

Attachment C: Example image of a potential lot
An example of an existing narrow lot exists adjacent to 413 North Black Avenue. This
could be a 32’x140’ lot, but only if what is built meets affordability standards.
Note: The previous condition of this lot was a 4 unit (14 bedroom) apartment building.
The structure was removed and a single-family house with detached garage/ADU was
recently completed on the left.
