which in essence may remove any incentive to construction homes on the smaller
lots. Upon making this statement, there was additional discussion about the
underlying premise for having the ground floor coverage requirements in the first
place. Mr. Zenner noted that the limitation was to ensure that home scale was
proportionate to available lot area and building area. Commissioners recognized
this purpose; however, still noted that a more flexible sliding scale would better
address the matter.
There was further discussion with respect to how the original ground floor
calculation was computed. Commissioners recommended that creating a flat 35%
percent lot coverage with the opportunity to seek a bonus may be a better
approach. Mr. Zenner noted he’d have to look at what the actual percentage should
be such that lots smaller than 5000 sq. ft. would not be permit greater ground floor
area than a standard 5000 sq. ft. lot such that conventional lot development be
discouraged. Commissioners agreed that evaluating this impact was appropriate.
With respect to the potential for a bonus in ground floor area, it was recommended
that a maximum of 40% may be appropriate if such lots were to utilize traditional
setback standards or standards similar to those found within the UDC relating to
solar or conservation subdivisions. Mr. Zenner stated he would look at the possible
standards that could be utilized from these existing provisions. He also
recommended that an increase in ground floor coverage could be tied to
“use-specific standards” applicable to the newly created lot sizes.
Having gained the added clarity on the Commission’s desired outcome relating to
the ground floor area limitations, Mr. Zenner moved onto the unfinished business
of definitions. He noted that the Commission’s prior discussion had raised concern
with the term “floor area”. Mr. Zenner noted the UDC and the City’s Taxation
provisions contained definition relating to this term. The UDC’s definition was
specific to uses within the floodplain regulation. Given the narrow nature of the
UDC’s definition Mr. Zenner noted that the Taxation definition was more
appropriate. He further noted that bolded text within the Taxation definition
would exclude all accessory structures (i.e. ADU’s, detached garages, and sheds)
from counting toward a lot’s maximum FAR.
There was general discussion on this point. It was a noted that by counting
everything within the foundation walls would also include a basement. There was
some concern with this; however, it was noted that such an inclusion is how
property is taxed and if a different definition was created it would likely result in
more confusion than clarity. A question was asked about the instance of a carport
being attached to a dwelling in lieu of a garage. Mr. Zenner noted that he’d have to
research that question, but thought given the exterior supports of the carport
(holding up its roof) were not on a foundation wall such area may not count toward
the dwelling’s FAR. There was also discussion on how this definition would impact
the new style of lots that could accommodate an ADU.
Mr. Zenner noted that Commissioner Loe raised a question at the March 7 Regular
Planning Commission meeting when discussion was occurring on the ADU
amendments about a statement in the work session memo in which it stated ADUs
were not being permitted on small lots. To clarify, Mr. Zenner noted that the
statement was meant to apply to lots smaller than 5000 sq. ft.. So with respect to
how a “medium-sized” lot using the reduced setbacks would be impacted by the
proposed Taxation definition of “floor area” it was noted that an ADU of any size
could be constructed on such a lot provided the total ground floor area limits that
were just discussed were not being exceeded.
Given this clarification, the Commissioners agreed to support the definition of
