• The site is located on 171st Avenue and the south side of the BNSF railroad
tracks. Adjacent land uses include agricultural and LeFebvre Trucking.
Rezoning
In order to construct the proposed tower, a rezoning to AT is required. This
overlay district was established to manage the proliferation of antenna
towers and to insure there proper placement regarding health, safety and
welfare of the community. This overlay district does not change the
underlying PUD zoning district, all the uses allowed and the dimensional
regulations in the PUD district will continue to be allowed on land zoned AT.
In considering a rezoning request of this nature, consideration should be
given to the existing conditions within the area directly and indirectly
affected by the proposed rezoning as well as the compatibility with
surrounding land uses.
The rezoning request should not adversely impact and would be compatible
with the zoning and current use of the property which is under consideration
for rezoning and adjacent properties. The applicant has indicated they need
• this tower in order to meet their communication and dispatch needs. The
applicant stated they investigated co-locating on the towers owned by AT&T
and APT and found that they could not meet their coverage needs.
Conditional Use Permit
Co-location Requirements
The applicant has indicated verbally they contacted the owners of the two
nearest towers, APT and AT&T and found they could not meet their
communication needs by co-locating on either of those towers.
Construction Requirements and Design Standards
The applicant is proposing to construct a lattice type tower with guy wires. It
will be located on the roof of their building. The only construction information
provided at the writing of this report showed the proposed height and type of
the tower, proposed location on the building and the spacing of the guy wires.
A lattice type tower is allowed because this is a private tower; a monopole
design is required for commercial wireless telecommunication towers.

• Signage, Lighting and Accessory Structures
No signs or advertising is proposed.
No accessory structures or equipment is shown in the information provided.
No illumination is proposed.
Setback and Height Requirements
The proposed tower complies with the setback requirements. The proposed
height of the tower is about 174 feet above grade. The tower itself is 150 feet
and it is located on the roof of the building which is approximately 24 feet
above grade. In order to have a 174 foot high tower the applicant has to
provide space for one additional user.
Recommendation
It is recommended the Planning Commission recommend approval of the
rezoning request to AT based on the following findings:
• 1. The rezoning is compatible with the surrounding land uses and would
not adversely affect the property under consideration for rezoning.
2. The proposed rezoning is necessary in order to provide effective
telecommunication and dispatch coverage for Morrell Companies.
3. The rezoning is in accordance with the Comprehensive Plan for the
city.

conditional use permit for a 174 foot wireless telecommunication tower and
supporting equipment with the following conditions:

2. The tower shall be a color that blends in with the surrounding
environment.

Dear Scott, • •• •
•
Regarding the prouose I'tower for Morrell Companies; the design allows for•up to 8,3 square feet of antenna plate
area. Morrell's antenna will use 1.26 square feet of the maximum leaving 7 square feet of available antenna space on
the tower .this should be adequate for•twb to three co-users to share the tower-with lvlorrell's. This'will allow•the
tower to meet the requirements of the ordinance(item D-2). Please give me a call if you have any questions.
•
Sincerely,
• /1 /.
