Ord No. 480-X00( Page 5
Portable Buildings:
• Special Exception Use regulations for portable buildings require that the building have a
masonry façade in compliance with the City's Masonry Ordinance. A variance is commonly
needed to this requirement due to the inherent nature of a portable building. Special
Exceptions Uses are considered by the Zoning Board of Adjustments and Masonry
variances are considered by the City Council. This requires the applicants to process two
applications in order to receive approval. This amendment proposes removing this from
Special Exception Uses and allowing this use with approval of a Specific Use Permit under
Section 45 of the Zoning Ordinance. The regulation proposed would closely follow those
under the current SEU section and those for Temporary Construction or Sales Facilities.
The Proposal is as follows.
Remove from SECTION 44.12.5 SPECIAL EXCEPTION USE POWERS and Insert under
SECTION 45.1.51 to be permitted is all district except RE-5, RE-7, SF-1A, SF-1B, SF-2,
SF-30, SF-20A, SF-20B, MF-1, MF-2, MH, PLOT SITE PLAN REQUIRED
11.12.5 45.1.51 Portable buildings not otherwise permitted under this ordinance, subject
to the following requirements of 45.21.
45.21 SPECIFIC REGULATIONS FOR PORTABLE BUILDINGS NOT OTHERWISE
PERMITTED UNDER THIS ORDINANCE
a Approval of a portable building shall be on a temporary basis only. Any permit
granted hereunder shall be for a maximum period of three (3) years, unless
otherwise approved by the City Council.

or federal code which regulates their construction or shall meet all requirements of
the City's building code.

previous condition

Ord. No 480-X0 ( Page 6
f. Portable buildings may also be subject to other requirements as deemed
necessary in order to promote public health, safety, welfare and aesthetics.
Sidewalks:
Zoning Ordinance No. 480, as amended
• The Zoning Ordinance requires sidewalks for all development requiring City Council
approval of a site plan In some instances, in particular with building elevation changes to
existing sites where there is no increase in building floor area or intensity of use, the
requirement may not be roughly proportional to the development. The proposal is to set a
threshold for when sidewalk construction is required related to increases in floor area or
off-street parking of the site Additionally, the proposal is to add a provision in which the
City Council can consider a variance to the sidewalk requirement where a hardship or
practical difficulty exists;
SECTION 33.19
SIDEWALK REQUIREMENTS —For all new development or existing development which
increases the existing floor area of building(s) or the number of parking spaces by twenty
(20) percent or more and fequiring require a City Council approved site plan, a five (5)-foot
wide concrete sidewalk shall be provided along all adjacent public streets unless identified in
the city's Pathways Plan, in which case the Subdivision Ordinance No. 483, as amended,
Section 5 06 shall apply. In addition, all non-residential development shall provide
pedestrian access to the City's existing or future trail system as identified in any City Council
adopted plan
The City Council may grant a variance to this regulation where compliance would present
extraordinary difficulties:
i. in the use of the property or;
ii. to construct due to characteristics of the development or surrounding properties.
Correct miscellaneous section references:
There are several references to other sections within the Zoning Ordinance as well as other City
codes which need to be updated This amendment is intended to correctly align all references
including the following:
Section 4 Definitions—"Building Line" Change references to pages 4-23 and 4-24,
Section 39 6 "FENCING AND SCREENING" "NON-RESIDENTIAL DISTRICTS — Change
reference from Section 39.6b to Section 39 6a.
Section 45 "Specific Use Permits"— Correct reference numbers to correspond with current
regulation sections and renumber in consecutive order
