CITY OR ST. JOSICPH Council Agenda Item 10(a)
MEETING DATE: September 2, 2010
AGENDA ITEM: Antenna Lease — Consent to Modify
SUBMITTED BY: Engineering, Public Works
BOARD /COMMISSION /COMMITTEE RECOMMENDATION:
PREVIOUS COUNCIL ACTION: The City Council has previously entered to a lease agreement with US
West Wireless, LLC to install and maintain antennas on the City Water Tower. The lease agreement
identifies the cost per antenna with is increased with inflation each year.
BACKGROUND INFORMATION: As you can see the City was approached in April by Buell Consulting to
modify the existing antennas on the Water Tower. BueII was required to deposit with the City $ 5,000 to
cover the cost for review and inspection. SEH forwarded the request to the Twin Cities office who has
staff that works on such items. They have reviewed the request and determined that request is to
modify the existing antennas, using the same number, to update to the most current technology.
Staff will conduct a pre construction meeting to address the items of concern and then SEH staff will
conduct period inspections to assure that the requirements are fulfilled. All costs incurred by the City
will be deducted from the escrow being held.

Dear Judy -
Pursuant to the above referenced agreement, Verizon Wireless, successor in interest to
US WEST Wireless is hereby requesting your consent to a change in the antenna
configuration at the above referenced site.
Verizon Wireless is in the process of upgrading their wireless network to the 4
Generation Technology known as "LTE" (Long Term Evolution). As technology
advances, it is necessary for Verizon Wireless to upgrade their equipment, which will
consist of replacing certain antennas at the site. The enclosed construction drawings
outline the specifics of this modification. A structural review of the site has been done,
and a copy of the engineer's letter is attached.
On page two of this letter, a form is provided for the City of St. Joseph to indicate their
consent for the proposed modification. Please complete the form and return it to me via
email or facsimile at 651- 225 -0795 as soon as possible.
Do not hesitate to contact me at 651 -361 -8111 with any questions or concerns you may

Antenna replacement.
Dear Mr. Edwards:
As requested, SSC has completed our analysis of the proposed Verizon antenna
replacement. The analysis was performed by reviewing information collected during
an SSC site visit on 12/05/09, a Verizon's SMR dated 11/13/09, and a report by
Robert Wozniak dated 5122/05. It is our understanding that there is (12) existing
antennas with (6) existing antennas being removed and (6) new antennas installed;
all new antennas are to be placed on the existing mounts.
The existing Verizon antennas, all at Elevation 109 ft., and mounted to the concrete
base of the water tower, are as follows:
• (6) APL869014 antennas (each 92" x 6" x 8 ", 12.1 lbs), two each sector.
• (0) LPA- 185080/8CF antennas (each 47.2" x 6.6" x 5.8 ", 9.0 lbs) two each
sector.
The proposed Verizon antenna configuration, also all at Elevation 109 ft. and
mounted on existing mounts, consists of the following:
• 16) APL869014 antennas (each 92" x 6 x 8", 12.1 lbs), two each sector.,
• (3) BXA 185085/12CF -2 antennas (each 72.4" x 6.1" x 4.1 ", 15.0 lbs), one
each sector.
• (3) BXA- 70080/8CF -2 antennas (each 94.6" x 8.0" x 5.9 ", 23.0 lbs), one each
sector. LTE antennas (all 94.5" x 15.2" x 14.1 ", 38 Ibs).

10(a) :5 -
After reviewing the proposed antenna locations and the above referenced structural
report, it is the opinion of SSC that the proposed antenna replacement will not create
a significant loading change or any overstressing of the tower structure or of the
existing mounts.
Assuming that the existing water tower is built in conformance with all applicable
codes, and is adequately supporting the existing loads, it is the opinion of SSC that
the existing structure will be adequate to support the proposed Verizon modifications.
Thank you, and please feel free to contact us if you require further information.
Sincerely,

Letter STCC St Joseph_7- 2- 10.pdf
Dear Terry:
We have completed the review of the information submitted by Buell Consulting Inc. on behalf
of Verizon Wireless for the upgrade of their equipment at the St. Joseph's water tower and
have the following comments for your review:
1. The new antennas will be larger the existing antennas. The two
existing center antennas are 47.5" long and weigh 7lbs, the new
antennas replacing them are 94.7" (231bs) and 72.4" (131bs) respectively. The
structural letters provided by Buell indicates that the
size and weight of the new antennas will not be an issue.
2. The plans do not make reference to the painting of the new antennas
and support poles to match the tank. Any new antennas, mounting poles and brackets should be
shop painted to match the existing tank.
3. Drawing A03, detail 3, Note indicates that the contractor is to
supply and install longer mounting pipes as needed. The drawings
should specify that any new mounting pipes or other mounting equipment needed for
the installation of these antennas be galvanized
and shop painted to match.
Attached please find the following pertinent information:
• Plan sheet A -1 illustrating the specific equipment in each sector to
be exchanged /upgraded
• manufacture's product sheet indicating the (to be installed) antennas
specifications for size /weight /and RF
• Engineers letter stating that the new equipment will not affect the
structural integrity of the existing support structure
It is our opinion that the issues referenced above are minor in nature and can be addressed
in the final construction drawings following the Bid -walk.
That said, we believe that the City of St. Joseph can proceed with project approval.
Following approval by the City a pre- construction meeting should be scheduled by the tenant
to include the City and Verizons's representatives prior to commencement of project
construction.
It is our understanding that the City wishes to have SEH provide inspection to include shop
observation of the surface preparation and painting of the antennas, and final field
installation prior to project closeout. Therefore Verizon should submit to the City an
overall project schedule prior to commencement.
If you have any comments or concerns on the information above please contact me directly at
651.490.2182.

Buell Consulting, Inc

Saint Paul, MN 55114
Dear Ms. Bernard:
In accordance with your request we have reviewed the plans submitted by SSC, dated March 18, 2010,
referencing the proposed Verizon equipment upgrade at the City's water tower, and have the following
comments for your review:
1. SCC should provide manufacture's product sheets indicating the (to be installed) antennas
specifications for size /weight/and RF.
2. SCC should revise the structural letter dated March 18, 2010, as the site address at the top is
incorrect and the second paragraph indicates that the antennas are to be mounted to the concrete
base of the tower. The pictures and plans provided indicate that this is a fluted tank, not a
composite tank.
If you have any questions regarding our comments, please contact me at 651.490.2160.
Sincerely,
Andy Roman
