2016 Street Improvements
➢ Contractor's Request for Payment No. 3 was approved at the August 2016 City Council
Meeting.
➢ Minor punch list items are scheduled to be completed by the end of September
and then final project closeout documents can be prepared for project closeout.
• 2016 Seal Coat and Crack Filling Project
➢ All work has been completed other than the second sweeping and 4" double
solid line (yellow paint) on 2201h Street N.
➢ Contractor's Request for Payment No. 1 is on the agenda as a separate business
item.
• 2016 Property Tax Report/Resources
➢ The Minnesota League's annual Property Tax Report and data tables are now
available. In the report, you'll learn that the trend of increasing property values
continued in Minnesota cities overall. You'll also find out about other market
value and tax capacity trends and get an update on current policy issues related
to the property tax system.

Road Ratings
➢ All the road ratings have been updated along with an updated colored map
showing the road ratings. The ratings were updated using the PASER Road
Rating System which is a visual system to rate the condition of pavements based
on rating number 10 (excellent) through 1 (failed).
• Guidance for dealing with Cell Towers and Small Cell Technologies
➢ With the increase in the use of cell phones and other mobile technology, cities
are getting more requests for placement of new cell towers and for placing cell
technology and distributed antenna systems (DAS) on city property and in public
rights of way. It's important for cities to proactively review their regulations to
ensure they are consistent with federal law, while still retaining control over the
deployment of structures and the use of rights of way.

Rating pavement surface condition
With an understanding of surface
distress, you can evaluate and rate
asphalt pavement surfaces. The rating
scale ranges from 10—excellent
condition to 1—failed. Most pave-
ments will deteriorate through the
phases listed in the rating scale. The
time it takes to go from excellent
condition (10) to complete failure (1)
depends largely on the quality of the
original construction and the amount
of heavy traffic loading.
Once significant deterioration begins,
it is common to see pavement decline
rapidly. This is usually due to a combi-
nation of loading and the effects of
additional moisture. As a pavement
ages and additional cracking develops,
more moisture can enter the pave-
ment and accelerate the rate of
deterioration.
Look at the photographs in this
section to become familiar with the
descriptions of the individual rating
categories. To evaluate an individual
pavement segment, first determine its
general condition. Is it relatively new,
toward the top end of the scale?
In very poor condition and at the
bottom of the scale? Or somewhere
in between? Next, think generally
about the appropriate maintenance
method. Use the rating categories
outlined below.
Finally, review the individual
pavement distress and select the
appropriate surface rating. Individual
pavements will not have all of the
types of distress listed for any
particular rating. They may have
only one or two types.
