ANALYSIS
Comprehensive Plan. The Comprehensive Plan establishes that water utilities are to be
provided for the purposes of accommodating anticipated growth with a compact, urban form
with staged expansion polices to manage development, provide for a balance of residential use
types, and increase commercial and industrial development. The City has adopted a Water
Item 3.4
2
System Management Plan to facilitate long-range development of utility infrastructure to meet
the service needs of existing and future users. The addition of water treatment facilities for the
water system is being undertaken to improve water quality for all users. The Well House #3 –
Water Treatment Plan project is an essential service necessary to implement the policies of the
Comprehensive Plan in accordance with the Water System Master Plan.
Zoning. The lot is zoned I-2, General Industrial District. The zoning of the property was
established on 24 September 2007 with platting of Dara Glen concurrent with approvals for
Kaleidoscope Charter School to the west. The I-2 District zoning reflects the guidance of the
Comprehensive Plan for development of the subject property for industrial land uses. The City
proposes to rezone the property to INS, Institutional District reflecting the proposed use of the
property for City utilities.
City utilities are allowed as a conditional use within both the I-2 and INS District. Requirements
for allowance within the INS District is as provided for by Section 11-90-6.G of the Zoning
Ordinance requiring approval of a Conditional Use Permit in accordance with Section 11-4-4 of
the Zoning Ordinance.
The Planning Commission and City Council must take into consideration the possible effects of
the Zoning Map amendment and Conditional Use Permit with their judgment based upon (but
not limited to) the criteria outlined in Section 11-3-2.F and Section 11-4-2.F of the Zoning
Ordinance:
1. The proposed action's consistency with the specific policies and provisions of the Otsego
Comprehensive Plan.
Comment: The 2023 Comprehensive Plan establish that costs incurred for the provision
of City services shall be financed by those who receive such service. This is implemented
by reducing the risk of payment for the provision of the utility systems by non-users
through utility phasing, identification of potential water revenue sources, establishment
of realistic growth expectations, and adoption of a Capital Improvement Plan. The
improvement of Well House #3 – Water Treatment Plant is consistent with the
Comprehensive Plan, Water System Master Plan and Capital Improvement Plan.
2. The proposed use's compatibility with present and future land uses of the area.
Comment: The subject property is guided for industrial use. There is an undeveloped
industrial lot to the north and undeveloped parcel guided for Office uses to the east of
the subject site. Kaleidoscope Charter School is located west of the subject property
across Kalland Avenue, which has an underlying guidance for industrial use. The
Kittredge Crossings subdivision is located to the south of the subject site and is separated
by increased setback and proposed/existing stormwater basins and wetlands. The
proposed. The proposed Well House #3 – Water Treatment Plant will not affect
surrounding properties.

3. The proposed use's conformity with all performance standards contained within the
Zoning Ordinance and other provisions of the City Code.
Comment: The proposed municipal well will comply with the applicable requirements of
the Zoning Ordinance and City Code.
4. Traffic generation of the proposed use in relation to capabilities of streets serving the
property.
Comment: The proposed use will not generate any traffic beyond service trips by Utilities
Department staff, which is within the capacity of Kalland Avenue as a local industrial
street.
5. The proposed use can be accommodated by existing public services and facilities and
will not overburden the City's service capacity.
Comment: The City has planned for development of the Well House #3 – Water
Treatment Plant to provide service capacity in accordance with the Comprehensive Plan,
Water System Master Plan, and Capital Improvement Plan.
Structure. The proposed 5,900 square foot structure encompasses piping equipment and
chemical storage for treatment of raw water drawn from Well House #3 located to the east at
Lachman Avenue and 77th Street. The finished treated water is then pumped from the Well
House #3 – Water Treatment Plant to the water towers for storage.
Section 11-17-4.D.2 of the Zoning Ordinance requires institutional uses have exterior finishes of
masonry or precast concrete panels having a surface treatment over a minimum of 65 percent
of any elevation facing a public street and use of masonry materials, precast concrete, fiber
cement, or other architectural paneling for 90 percent of the other elevations. The proposed
structure uses precast concrete panels with a combination of limestone block and exposed
aggregate finish. There is a horizontal metal panel surrounding the upper section of the
structure above the interior piping area, and metal roof. The proposed exterior finish of the
proposed building complies with the requirements of the Zoning Ordinance.
Buildings within the INS District are limited to a maximum height of three stories or 40 feet.
The proposed structure is one story and measures 24 feet to the midpoint of the pitched roof
section. The height of the proposed structure complies with the limits established by the
Zoning Ordinance.

Lot Requirements. Section 11-90-7.A.1 of the Zoning Ordinance requires uses within the INS
District to have a minimum lot area of five acres unless reduced by Conditional Use Permit.
There is no minimum lot width requirement within the INS District. The subject property is 2.5
acres in area. Allowance of the proposed use of the property for City utility purposes through
approval of a Conditional Use Permit will be subject to compliance with applicable setback
requirements.
Setbacks. Section 11-90-7.B of the Zoning Ordinance requires that the utility structures be
subject to the setback requirements shown in the table below. The proposed building complies
with the setback requirements applicable within the INS District, indicating that the area of the
lot is suitable for the proposed use.

Proposed 85ft. 75ft. 65ft. 277ft.
Access. The utility facility is to be accessed from a single driveway off of Kalland Avenue.
Kalland Avenue is constructed as a local industrial street. The proposed access is to be
constructed with a concrete apron that is 30 feet wide. Section 11-21-6.C.2 of the Zoning
Ordinance establishes that a street access for non-residential uses is limited to 24 feet in width
unless approved by the City Engineer to allow for adequate turning movements.
The interior drive aisle provide access to service doors on the west and south elevations of the
proposed structure. The interior drive aisles are to be surfaced with asphalt include perimeter
concrete curb as required by Sections 11-21-7.C and 11-21-7.D of the Zoning Ordinance.
There are no designated parking spaces within the subject property, which will not be a staffed
facility. There is sufficient space within the interior drive aisles for Utilities Department Staff
monitoring the facility or performing maintenance to park without interfering with traffic on
Kalland Avenue. The drive aisles are also designed to accommodate truck maneuvers within the
site so as not to require backing off of or onto Kalland Avenue.
The design and construction specifications for access and off-street parking areas are subject to
review and approval of the City Engineer.
Exterior Lighting. The submitted plans detail two exterior light fixtures at the service doors on
the west elevation of the proposed building. The light fixtures must have a 90 degree
horizontal cut-off to cast light at the ground, not towards Kalland Avenue. All exterior lighting
is subject to review and approval of the Zoning Administrator.

Grading. Plans for grading, drainage, and erosion control for development the subject property
have been prepared. The side development includes a stormwater basin for management of
stormwater runoff created by the impervious surfaces within the lot. No landscaping of the
subject property is proposed beyond seeding for erosion control. A more detailed plan for low
maintenance, low water natural plantings should be considered with input from the Zoning
Administrator. All stormwater management issues are subject to review and approval of the
City Engineer.
