TO: Mayor & City Council
Mark McNeill, City Administrator
FROM: Bruce Loney, Public Works Director
SUBJECT: Request of PCI Roads, Inc. for Extending Work Hours on
Scott County Road 21 Project
DATE: April 5, 2011
INTRODUCTION:
PCI Roads, Inc., the paving contractor for the County Road 21 Improvement Project from
CSAH 42 to CSAH 18, has requested that City Code Sec. 10.60, Noise Elimination and
Noise Prevention, Subd. 3, Hourly Restrictions on Certain Operations, be suspended for
certain work hours.
BACKGROUND:
The above named section of the City Code restricts the hours of operation from 7:00
A.M. to 10:00 P.M. on weekdays, and from 9:00 A.M. to 9:00 P.M. on weekends and
holidays.
PCI Roads, Inc. is requesting a suspension on the hours to allow for work 24 hours a day,
for approximately 35 days of concrete paving beginning May 1, 2011. The contractor
needs to saw the joints in the concrete pavement within certain timelines which could be
all night in some cases. If the joints are not sawed within a certain timeline after paving,
mid paved cracks can develop and the pavement will not be acceptable.
Staff would recommend that if the suspension of hours is granted from May 1, 2011 to
October 1, 2011, that the approval is subject to the following conditions:
1. Approval is contingent upon minimizing noise exposure and this approval is for 35
days with 15 days adjacent to residential property and for concrete pavement sawing
only.
2. If property owner complaints are received by the City, the suspension can be revoked
or additional conditions can be imposed at the discretion of the City Engineer.
3. The County /contractor shall provide written notification to adjacent residents to C.R.
21 of this concrete sawing work during the night prior to the work commencing.
If Council approves the suspension, a public notice to meet the City Code requirements
and notice such as a news release would be placed in the Shakopee Valley News.
ALTERNATIVES:
1. Approve the suspension of City Code Sec. 10.60, Noise Elimination and Noise
Prevention, Subd. 3, Hourly Restrictions on Certain Operations, per this memo, and
direct staff to publish notice of the suspension terms with the conditions as
recommended by staff.
2. Approve the suspension of City Code Sec. 10.60, Noise Elimination and Noise
Prevention, Subd. 3, Hourly Restrictions on Certain Operations, for some other period
of time as determined appropriate by the City Council, and direct staff to publish
notice of the suspension terms.
3. Do not approve the suspension of City Code Sec. 10.60, Noise Elimination and Noise
Prevention, Subd. 3, Hourly Restrictions on Certain Operations, D.
RECOMMENDATION:
Staff recommends Alternative No. 1, as the concrete pavement sawing must be done
within certain timelines to produce a quality product.
ACTION REQUESTED:
1. Offer a motion approving a suspension of City Code Sec. 10.60, Noise
Elimination and Noise Prevention, Subd. 3, Hourly Restrictions on Certain
Operations, D, per this memo, and direct staff to publish notice of the suspension
terms with the conditions as recommended by staff.

Re: Scott County Road 21 Construction
Noise Variance
Dear Mr. Loney,
PCiRoads is a subcontractor to Enebak Construction Co. on the new construction of
Scott CSAH 21 from CSAH 42 to just north of Hansen Avenue. PCiRoads will be
constructing the concrete pavement which, as you may know, requires the sawing of
control joints at 15' intervals approximately 6 — 24 hours after placement. The time of
sawing is largely dependent upon temperature which effects the rate at which the
concrete pavement sets -up.
We really have no way of knowing exactly when the concrete will be sawed except that it
will include night work. The sawing has to be completed in a very small window relative
to its strength gain. Any delay in this operation will cause random cracking.
There are approximately 35 days of concrete paving beginning about May 1' with the
majority of paving being completed in the first month. The northerly area of the project,
which is in a residential area, could be expected to have approximately 15 paving days.
Some days may include sawing all night while others may not have any sawing past
10:00 p.m., although you should expect most days will include sawing into the early
morning hours. There are multiple phases to tie CSAH 21 into CSAH 18, therefore, there
will be work continuing into mid- summer. However, those tie -in areas are generally
small and should have little, if any night time sawing.
PCiRoads will make every effort to minimize the disturbance to the local residents,
however, I want to re- emphasize that the concrete must be sawed in that very small
window to prevent damage to the new pavement. Therefore, we are requesting a
variance to your noise ordinance that would allow concrete sawing operations during
night time hours during concrete paving operations.
Please call me with any questions you may have.
Sincerely,
PCiRoads, LLC
