Memorandum
TO: Mayor & City Council
Mark McNeill, City Administrator
FROM: Bruce Loney, Public Works Director
SUBJECT: Overhead Power Relocation on CSAH 69 Reconstruction
DATE: December 20, 2011
INTRODUCTION:
BACKGROUND:
S r 7 T
This agenda item is to consider relocation of existing overhead or undergrounding of the existing
power lines on the proposed 2012 County State Aid Highway (CSAH) 69 Reconstruction Project
and was tabled at the December 6, 2011 Council meeting.
On September 6, 2011, the City Council approved a layout drawing on the Scott County CSAH
69 Reconstruction Project. Associated with this project is the relocation of existing overhead
-power lines. Council has the right to require the existing power lines go underground or be
relocated overhead.
Previously, Council was given a memo from Joe Adams of Shakopee Public Utilities
Commission (SPUC) in regard to the relocation of this facility that has gone to the November 2,
2011 SPUC meeting. Mr. Adams outlines the cost alternatives for removal of existing overhead,
for relocating overhead or undergrounding power lines. Attached is an e -mail from Joe Adam's
on the undergrounding of power lines, from Scott Street to Shakopee Substation, in which no
property owner would have to go to an underground service with this mainline undergrounding
unless they desired to pay for that cost.
In review of the project area, the cost of undergrounding power lines is more than overhead due
to rock excavation. The SPU Commission voted to accept the estimated costs and move this
item to the City Council for action, per the City's Right -of -Way Management Ordinance.
In review of the items listed in Mr. Adam's memo and e-mail, staff would recommend relocating
the existing overhead line from the Shakopee Substation to Scott Street and to be placed
underground.
Staff would not recommend the undergrounding of the 1 2 °d and 3 overhead primary
crossings over CSAH 69 at just west of the substation, north of the railroad bridge and 3rd
Avenue, respectively. The reason being is the high cost of undergrounding in these areas due to
rock excavation.
ALTERNATIVES:
1. Approve a motion determining that the existing overhead power lines on CSAH 69, from
the Shakopee Substation to Scott Street be relocated and shall be placed underground.
2. Approve a motion determining that the existing overhead power lines on CSAH 69, from
the Shakopee Substation to Scott Street shall remain overhead.
3. Approve a motion determining that the existing overhead power line crossings on CSAH
69 at west of Shakopee Substation, north of railroad bridge and 3 Avenue remain
overhead.
4. Table for additional information.
RECOMMENDATION:
Staff would recommend Alternative No. 1 and No. 3.
ACTION REQUESTED:
1. Approve a motion determining that the existing overhead power lines on CSAH 69, from
the Shakopee Substation to Scott Street be relocated and shall be placed underground.
2. Approve a motion determining that the existing overhead power line crossings on CSAH
69 at west of Shakopee Substation, north of railroad bridge and 3 Avenue remain
overhead.

Bruce —
This is to confirm our telephone discussion. First of all I apologize to you and the City council for missing the meeting on December
6' I intended to go and got caught up in an after school activity with my kids.
The underground relocations costs that I previously submitted to you do include removing the overhead crossings east of our
Shakopee substation down to Scott Street. We would place those primary wires underground across CR 69. However, we did not
include the cost to have the service lines to those parcels on the south side of Cr 69, e.g. Mike's Auto, etc. placed underground. To
do so would require the customers to convert their service to underground, since it is SPUC' policy that underground services be
owned and maintained by the customer while the utility owns and maintains overhead services up to the customer's mast on their
building. Consequently, and because no customers have expressed a desire to have their service lines placed underground, we plan
to have the underground crossings of CR 69 go back up onto the poles that are located outside the CR 69 right of way to continue
the overhead services that are presently in place.
Please contact me if there are any other questions about the project.
Thanks,
Joe
