ANALYSIS
Comprehensive Plan. The 2023 Comprehensive Plan guides the subject property for Industrial
land uses within the West Sewer District. The existing use of the subject property as a
contractor business is consistent with the guided land use of the subject property. The City’s
economic development goals further encourage in-place expansion of existing industrial
business to create employment opportunities, expand tax base within Otsego, and utilize land
efficiently. The proposed office building expansion is consistent with the 2023 Comprehensive
Plan.
Zoning. The subject property is zoned I-2, General Industrial District. The office component of
the construction contractor facility is a permitted use within the I-2 District.
Surrounding Uses. The table below summarizes existing and planned land uses surrounding
the subject property. The proposed expansion of the office use within the subject property will
be compatible with existing and planned land uses in the area.

Building Height. Principal buildings within the I-2 District are limited to a height of four stories
or 48 feet as required by Section 11-86-9 of the Zoning Ordinance. The proposed office building
expansion is two stories and 28 feet in height consistent with the height of the existing office
building. The height of the office building expansion complies with the allowances of the I-2
District.
Building Coverage. Section 11-86-8 of the Zoning Ordinance limits building coverage to 50
percent of the lot area. With the proposed office building expansion, buildings will cover
65,615 square feet of the 45.81 acre subject property. The proposed 32.9 percent building
coverage of the subject property complies with the Zoning Ordinance.
Lot Requirements. Lots within the I-2 District must have a minimum area of 2.0 acres and
minimum width of 200 feet to a public street. The subject property is 45.81 acres in area and

reduce the number of required parking stalls by 29 spaces. The number of existing off-street
parking stalls complies with the requirements of the Zoning Ordinance with any additional build
out of the office building expansion subject to additional review as provided for by Section 11-
21-4.D of the Zoning Ordinance.
Landscaping. The original site and building plan approval included a landscape plan. The

where the proposed expansion is to be constructed. As a result of the pre-planning for the
expansion by the property owner, there is no removal of trees installed with the initial site
development. No landscape plan has been submitted related to the proposed office expansion,
but is not required based on no change to the approved landscape plan.

Exterior Lighting. The submitted plans do not include an updated exterior lighting plan. Any
additional exterior lighting to be installed with the office building expansion must comply with
the provisions of Section 20-16-6 of the Zoning Ordinance. All exterior lighting is subject to
review and approval of the Zoning Administrator prior to issuance of a building permit.
Trash. Section 20-18-4.C of the Zoning Ordinance requires trash and recycling containers
stored outside must be within an enclosure at least six feet in height and constructed of
materials consistent with that used for the principal building. If outdoor storage of trash and
recycling containers occurs, plans for an enclosure must be submitted prior to issuance of a
building permit and are subject to review of the Zoning Administrator.
Signs. The submitted plans indicate only an additional wall sign above the entrance to the
office building expansion within the subject property. All signs are to comply with Section 37 of
the Zoning Ordinance and a sign permit is required prior to placement of signs upon the subject
property.

plan for alteration of the existing utility connections necessary for the proposed office building
expansion. All utility plans are subject to review and approval of the City Engineer. Utility
Availability Charges were paid with the plat approval for the subject property. Utility
connection charges for the proposed office building expansion will be collected at the time a
building permit is issued in accordance with Title 8, Chapter 1 of the City Code.
Performance Agreement. Section 11-9-4 of the Zoning Ordinance provides that the site and
building plan approval and the stipulations, limitations, and conditions therein be applied to the
subject property. All written and graphic materials officially submitted to the City are deemed
to be a formal agreement between the property owner and the City. Once approved, no
changes, modifications or alterations may be made to any plan detail, standard, or
specifications without prior submission of a plan modification request to the Zoning
Administrator for review and approval. It is not necessary for the property owner to enter into
a separate Site Improvement Performance Agreement with the City for the proposed office
building expansion.
