TH 212/312 Update - Project No. 03-09
DISCUSSION
Representatives from MnDOT are planning to be in attendance to give the
Council an update on the progress of the TH 212 project. The presentation will
include what is scheduled for this year's summer construction season and the
tentative schedule for the next two years.
After the MnDOT presentation, staff would like to discuss potential changes to
the TH 212 contract the City has with MnDOT. On February 13, 2006, Council
approved a change order for installation of street lights on the new Powers
Boulevard bridge over TH 212. MnDOT has included lights on the TH 101
bridge over TH 212 in their contract, however, the lights that are included in the
contract are only on the east side of the bridge. To have a consistent light pattern
over the entire bridge, some of the lights should be moved to the west side of the
bridge and one light standard added. To move the light standards, MnDOT would
charge the City for the increased cost. The City received a quote from ZRC for
the work. The work includes adding one lighting unit and blister (lighting unit
foundation) to the bridge, conduit system to the west side of the bridge and
wiring. The total cost for the work quoted is $26,250.
The City staff is working with MnDOT on acquisition of a remnant piece of right-
of-way along the TH 212 corridor for sighting of a future satellite fire station.
MnDOT has verbally indicated the parcel of property would be available to the
City, but official notice has not been received by the City. Plans for Lyman
Boulevard are nearing completion and staff would like to ask MnDOT to include
improvements into the TH 212 contract to plan for the future fire station. It would
be more cost effective to make these improvements now then wait until the fire
station is ready to be built.
The improvements for the future fire station include sanitary sewer, storm water,
turn lane and gas main lowering. Stubbing a sanitary sewer pipe from Lake Susan
Drive across Lyman Boulevard to the property should be included since Lyman
Boulevard will be closed this summer for two months. The sanitary sewer can
easily be installed during the closure. If the sewer pipe is not put in at this time,
the sewer would need to be jacked under Lyman Boulevard which would be

significantly more expensive. The TH 212 project will be constructing a
stormwater treatment pond on west of the proposed fire station site. This pond
can easily be expanded to accommodate the future stormwater run off of the fire
station. Since Lyman Boulevard will be reconstructed and widened, an eastbound
right turn lane should be included in the design for the fire station. A Magellan
Gas Pipe line runs along Lyman Boulevard. MnDOT is planning to have the
Magellan lowered the pipe line east of the site for the TH 212 project. The pipe
line should be lowered on the fire station site at the same time as the TH 212
project.
Staff has estimated the cost for the fire station improvements as follows:
Sewer Extension Improvements
Pond Expansion Improvements
Lower Magellan Pipeline
Turn Lane Improvements
$ 20,000
$ 15,000
$ 35,000
$ 110,000
$ 180,000
The total costs for the improvements discussed including the street lights
improvements at TH 101 bridge and the five fire station improvement items are
$206,250.
The changes to the TH 212 Project are as follows:
Improvement Items Costs (+-)
Delete - Bluff Creek Bridge -$260,000
Add - Lights on Powers Bridge +$121,000
Add - TH 101 Bridge Light Changes +$ 26,250
Add - Estimate for Satellite Fire Station Improvements +$180,000
Total $67,250
The changes being proposed would require increasing the TH 212 contract by
$67,250. No other major changes to the TH 212 project are anticipated at this
time.
Funding for these improvements is proposed from the State of Minnesota loan
agreement that the City is utilizing to fund the City improvements.
