Re: ADUs in Bozeman's May 8, 2017 draft UDC Update
The May 8, 2017 draft UDC update introduces a new dimension to
Accessory Dwelling Units1: second (Accessory) homes (Dwelling Units) on
lots with alley access, hundreds of which are in our National Register
Historic Districts. Historic preservation has long been a successful aspect
of city planning in Bozeman. Such wholesale construction of new Alley
Dwelling Units will invariably create zones of substandard quality of life,
and will futilely sacrifice Bozeman's historic districts forever.
The guiding principles for Bozeman infill (Saunders/Thomas Commission
Memorandum, September 23, 2013) included "All citizens of the
community should receive equivalent levels of services." A walking tour of
Bozeman's alleys in the Bon Ton, North Bozeman, and Cooper Park (see
http://bozeman-history.net/adu/Alleys.m4v) shows them to be narrow,
unpaved, ungraded (and unplowed), lacking sidewalks for pedestrian
safety, lacking streetlights for crime prevention, and lacking safe egress
from alleys to higher classification roadways. Are such levels of services
equivalent to our normal residential neighborhoods? Obviously not.
Notwithstanding these attributes, our present alleys provide several
practical elements of our quality of life: trash and recycling collection,
access to garages and sheds, access to yards and gardens, delivery of
cable and telephone services. Are these services important to us? Of
course they are. Do we want to move them onto the normal residential
streets of our historic districts? No way.
ADUs appear in several sections of the draft UDC update:
1. In neighborhoods zoned R-1 and R-S, the draft UDC update limits
ADUs to those that are integrated into primary residences2. Where
1 Sec. 38.360.040 - Item D.2.a 2 Table 38.310.030 - Note 9
FINAL DRAFT: BPAG position UDC ADUs 2
an historic district overlies an area zoned R-1 or R-S, this provides a
crucial protection for the architectural integrity of the district.
2. In neighborhoods zoned R-1 and R-S, the draft UDC update limits
above-garage ADUs to subdivisions with plat approval after January
1, 19973. Where an historic district overlies an area zoned R-1 or R-
S, this is another crucial protection for the architectural integrity of
the district.
3. On the other hand, the draft UDC update allows detached ADUs on
lots with alley access in all R-2, R-3, R-4, R-5, R-O, and REMU
districts4.
It is essential to recognize that only a small fraction of Bozeman's
residential historic districts are zoned R-1, and none are zoned R-S.
Primarily, the historic districts are zoned R-2 (Cooper Park, South Tracy /
South Black, South Tracy, Lindley Place, North Tracy). The Bon Ton and
Cooper Park historic districts include areas zoned R-4. These districts are
just as important to Bozeman's historic preservation as Bon Ton!
In the spirit of the stated guiding principle for Bozeman infill by providing all
Bozeman citizens with equivalent levels of services, while preserving
Bozeman as a place with high quality of life and pride in its history, we
suggest the following changes to the draft UDC:
1. Reduce the scope of applicability of Sec. 38.360.040.D, which
presently includes R-2, R-3, R-4, R-5, R-O, and REMU zoning
districts, to R-5, R-O, REMU zoning districts only.
2. Alternatively, create an exception to the draft UDC's Sec.
38.360.040.D for National Register Historic Districts or for
subdivisions with plat approval before January 1, 1997.
3. Incorporate these changes into the R-2, R-3, and R-4 columns of the
Accessory dwelling units row of Table 38.310.030.
4. Add the R-2, R-3, and R-4 districts to Note 6 of Table 38.310.030, or
add to this note a condition permitting ADUs above garages only
outside National Register Historic Districts.

Postcript.
The Historic Alleys Walking Tour shown at http://bozeman-
history.net/adu/Alleys.m4v covered 20-30% of the total length of
Bozeman's historic districts alleys -- enough to be representative. Alley
widths can measured in various meaningful ways:
1. Physical alley widths defined by measuring the distance between
well-defined fixed structures such as utility poles, transformers,
garages, sheds, etc.,
2. Physical alley widths defined by measuring the distance between
well-defined non-fixed structures such as dumpsters, trashcans,
household and garden debris, and construction debris.
3. Line-of-sight alley widths defined by visibility from vehicles as low as
passenger and police cars to vehicles as high as trash trucks and
fire trucks.
4. Line-of-sight and limit-of-visibility alley width defined by structures,
but also by less-well-defined live objects such as trees, shrubs, and
trellises.
5. Limit-of-visibility (say, where alleys intersect higher classification
roadways and sidewalks, or places where children play) are less
precisely measured, but very important.
Using surveyor’s tape, physical alley widths were measured in many
locations along the Historic Alleys Walking Tour. In many locations
physical alley widths as small as 13 ft were found. Line of sight and limits
of visibility alley widths were often several feet smaller.
A wide range of alley width codes are found in other cites. Most alley
widths are defined by utility purposes, not alley ADUs. Of the alley widths
that are specifically defined for dwelling purposes, those based on the
most diagnostically valuable experience are those of Washington, DC.
Alley dwelling units were started there when many former slaves moved
north after the Civil War. During the intervening 150 years of experience
code (and societal) standards have varied considerably. The existing
regulations strictly regulate residences on alley lots in all zones. Presently,
a single-family alley dwelling is permitted only on an alley lot accessible via
a 30-foot wide alley or alley network.
