Stephanie,
Thanks for sending this—we did receive it, but since we distribute Committee member emails on a
different schedule than the other memos, etc. it had not yet been posted to the email
communications folder. Rest assured that it has been added and will be distributed soon.
I've added a few thoughts and responses to your message below in purple.
Thanks,
Erik Olson

Subject: MHCAC- Further Consideration for Detached Plexes, Building Width, and Garage Standards
Hi Erik,
I would like to clarify my thinking and provide context for my votes from Meeting 3 (Key Issue 2—
Scale and Character for Dup/Tri/Quad plexes) and Meeting 4 (relating to Townhouse Garage
Standards).
Please see my comments below relating specifically to: (1) the scale and character of dup/tri/quad
plexes, especially if allowing detached units, (2) limits on building width, and (3) garage standards.
(1) Further Considerations if Allowing Detached Plexes:
Based on our discussion in Meeting 3 and further review of shared email comments, I would like to
modify my responses to provide more nuance and context relating to the relationship of detached
versus attached and how the scale and character of each form would be handled.
If detached plexes are not allowed, the existing bulk and massing standards would seem to suffice as
the single unit would likely be of similar scale and form to the single family homes of the
neighborhood. However, if detached plexes are allowed, the nature of these units could be
significantly different from the existing character and would warrant further design standards to
create cohesive integration with existing neighborhood character.
Simply stated, if detached plexes are allowed, I believe that bulk and massing standards should be
adjusted to more tightly control building sizes. If detached plexes are not allowed, I believe that
existing bulk and massing standards can be applied to all housing types.
Unfortunately, we were able to clarify that this would not be allowed under the state's Division 46
rules—since even detached plexes are considered "middle housing" and must be treated the same
as attached plexes. Thus, we would only be able to accomplish this through an "alternative"track
where we would need to take extra measures to show that this would not produce unreasonable
cost and delay for this type of middle housing construction. Even DLCD thought it'd be possible to
prove that additional design standards for detached plexes would not produce such cost/delay,
though it may not be possible for the City to do this on the same timeline as the other amendments.
Along these lines, I am curious how SB 458 would align to and/or affect current zoning designations
for minimum lot size. By allowing detached plexes, it appears that would allow any lot to be
partitioned into 4 parcels, unless otherwise protected. I would like to suggest that the lot
partitioning under SB 458 would only apply to the attached plexes (a required element of HB 2001),
and would not apply to the detached plexes (which are not a required component of HB 2001 and
therefore not necessarily eligible under SB 458).
Similar to the above, I wanted to clarify that this would not be allowed under the state's Division 46
rules—since detached plexes must be treated as all other middle housing, according to DLCD.
That aside, I am having some difficulty following this line of thought... under SB 458, any lot with
attached plexes, townhouses, and cottage clusters may be partitioned into four or more lots through
an expedited process. Cottage cluster units in particular will have a detached character and will likely
contain more than four units per cottage cluster project. What is your specific concern about
partitions for detached plexes? (With respect to your statement above expressing concerns that any
lot could be partitioned into four parcels under SB 458—I wanted to note that this would be true for
all other middle housing types, regardless of if we allow it for detached plexes.)
Another area of overlap, and potential confusion, exists between detached quadplexes and 4-unit
cottage clusters. One way to improve clarity, could be to allow detached dup/tri plexes, but not
detached quadplexes, as detached quadplexes would instead fall under the cottage cluster
standards for characteristics including building size, siting, and orientation.
(2) Further Considerations on Limiting Building Width:
There was great discussion during the meeting around how to best achieve an integrated, cohesive
feel even for larger attached buildings. While design standards and bulk and massing standards will
provide significant guidance on how to develop a well-integrated large-scale unit, I think it is
important to also address the issue of open space and the relationship of buildings with that open
space.
This issue relates not only to the visual impact and sense of place, but also to issues of walkability,
connectivity, and accessibility. On a single parcel,the existing set-backs and bulk& massing and
design standards seem adequate to address issues of integrating into the neighborhood character.
However, when consolidating parcels,the loss of interior set-backs could result in very long
stretches of connected townhouses or other units without a physical break for accessibility and
visual relief. I would like to suggest that when parcels are consolidated,the overall amount of open
space that would have been required as setbacks on the pre-consolidated individual parcels would
be retained as a requirement for the newly consolidated parcel.
The City has lot coverage standards that would partially address the "open space" component of
your concern, as the percentage of a lot that is allowed to contain structures would still apply to a
larger consolidated lot.
I understand the concerns about neighborhood character, but I have some questions about the way
you're discussing "walkability, connectivity, and accessibility" in the context of this discussion. How
would setbacks between,for instance,townhouse units, accomplish these goals?The City does not
typically create policy to expand public access to private yards, and even with setbacks there would
likely be no public accessways to the yard space. Given that the space is intended for occupants of
the townhomes, wouldn't they continue to have access to their yard space through their unit? I
think we should be deliberate about increasing accessibility/walkability/connectivity in our
communities, but I don't quite understand how those issues would be addressed through providing
separation between middle housing units.
When I mentioned this concept briefly in our Sept 15 meeting (after the vote had been completed in
a previous meeting), the question was raised: If this concept were applied, what would be the
benefit of consolidating parcels? I do believe there would still be economies of scale for the overall
project, as well as improved flexibilities for developing the project infrastructure. There could be
flexibility granted in terms of how those required open spaces (from lost interior setbacks) could be
applied. This could be especially helpful to preserve significant trees. I think that requiring these
spaces would better preserve the neighborhood-scale cadence of structure/open space and would
create a more cohesive result.
(3) Garage standards
In Meeting 4, we discussed options for the Townhouse Garage Standards, including a choice
between applying the existing garage standards or applying the Model Code standards for
townhouses. My aim with this vote is to minimize negative visual impacts of prominent front-facing
garages, without negatively impacting parking and accessibility. I voted to apply existing standards;
however, I would only choose this option if the existing single family home garage standard was
tightened to allow a maximum garage width of 50%of front façade, or an even lower threshold (it is
currently set at 60%). This proposed change aligns with the results of the neighborhood character
survey findings that prominent garages are common but are not desired.
There was a comment made by a committee member during the meeting that suggested changes to
the existing single family home garage standard was out of scope, however it is my understanding
from the City and consultants, that such a change to the existing single family home garage standard
is within scope. I would ask for your clarification so that the committee can make a fully informed
recommendation.
I've clarified at recent meetings that—yes, you're correct that changes to single-family zoning are
within scope of the project. Apologies if this was not made clear in the questions and memos.
Thank you for your consideration of these comments.
Also, I am hoping we will have an opportunity to revisit the committee votes as part of the closeout
process and wrap up in making "official" recommendations to the City, as new details have
continued to emerge on a number of topics during the course of the meetings, but after the close of
initial voting.
I'm not sure we'll be able to revisit all votes, but we could revisit questions where we've received
additional questions/comments/concerns following the vote. Generally speaking, we were
thinking that we would use the meeting to clarify important details on previous recommendations—
i.e. if we allow detached plexes, should we just allow duplexes? Duplexes and triplexes? Or all
plexes?, etc.
Let me know if you have any specific questions you'd like to revisit after getting a better sense of
how the regulations would function over the course of subsequent meetings.
Best,
Stephanie
