Dear Shannon:
In accordance with the request of the City we have reviewed the plans submitted by Telecad Wireless
dated April 16, 2014 referencing the construction of the proposed Sprint Project at the Tower Street
water tower in the City of Prior Lake, Minnesota.
Based on our review and the above information as provided by Telecad Wireless, it is our opinion the
City of Prior Lake can proceed with approval of this phase of the project the remaining comments have
been addressed to the satisfaction of the city. Following approval by the City a pre-construction meeting
must be scheduled by the tenant to include the City, SEH, the contractor and Sprint representatives
prior to commencement of project construction.
If you have any questions regarding our comments, please contact me directly at 651.765.2971.
Sincerely,
John Cvek
Senior Technician

Site Name: Prior Lake Water Tank
Site Address: 4741 Tower St, Prior Lake, MN 55372
Structure Type: Existing Water Tower
As requested, Selective Site Consultants, Inc. (SSC) has reviewed documents
regarding the subject site in order to assess its structural capability to support the
proposed antenna loadings. Documents reviewed include SSC Rev 0 drawings
dated 09-10-12 and current photos.
1. Interim Configuration:
• Elevation 80': (2) existing CDMA antennas, (1) KMW ET-X-TS-70-15-
62-18-IR-RD antenna, (1) RRH-C2A 800 MHz RRU, and (1) RRH-P4
1900 MHz RRU per sector mounted on frames attached to the leg of the
existing water tower corresponding to azimuths of 20 and 260 degrees.
• Elevation 80': (1) Andrew VHLP2-18 microwave dish mounted on a
frame attached to the leg of the existing water tower corresponding to an
azimuth of 312 degrees.
• Elevation 90': (2) existing CDMA antennas, (1) KMW ET-X-TS-70-15-
62-18-IR-RD antenna, (1) RRH-C2A 800 MHz RRU, and (1) RRH-P4
1900 MHz RRU per sector mounted on a frame attached to the leg of the
existing water tower corresponding to an azimuth of 120 degrees.
2. Final Configuration:
• Elevation 80': (1) KMW ET-X-TS-70-15-62-18-IR-RD antenna, (1) RRH-
C2A 800 MHz RRU, and (1) RRH-P4 1900 MHz RRU per sector mounted
on frames attached to the leg of the existing water tower corresponding to
azimuths of 20 and 260 degrees.
• Elevation 80': (1) Andrew VHLP2-18 microwave dish mounted on a
frame attached to the leg of the existing water tower corresponding to an
azimuth of 312 degrees.
• Elevation 90': (1) KMW ET-X-TS-70-15-62-18-IR-RD antenna, (1) RRH-
C2A 800 MHz RRU, and (1) RRH-P4 1900 MHz RRU per sector mounted
on a frame attached to the leg of the existing water tower corresponding
to an azimuth of 120 degrees.

The proposed antennas are to be mounted on existing frames attached to the legs of
the existing water tower and at the same centerline as the existing antennas. The
weight of the antennas and RRUs will be insignificant when compared to the gravity
loads carried by the water tower. The additional loads imparted to the water tower
by the proposed antennas will create less than a 5% increase in stresses. Per the
IBC code section 3403 the structure will be adequate for the proposed loads. The
existing frames will also be adequate to support the wind imparted by the proposed
antennas.
Assuming that the existing structure is built per all applicable codes and adequately
supports the existing loads it is the opinion of SSC that the existing structure will be 1
adequate to support the proposed interim and final Sprint installation.
Thank you, and please feel free to contact us if you require further information.
