• Patching
For the past few weeks, Streets
maintenance crews have been out
patching City streets. The object is to
make repairs to small areas showing
surface distress so they do not
become larger problems in the next
few years. Crews use a milling
machine to remove the distressed
asphalt and a street sweeper to
remove the debris. This leaves an
area with a uniform depth that
allows better adhesion of the asphalt.
The vertical sides created by the milling
machine allow for a better joint with the
existing asphalt and prevents raveling at
the edges common to patches placed
over irregular surface distresses. Crews
will be out patching through the fall as
they work to prepare City streets for
winter.
• Flooding
Rainstorms throughout the summer have
caused a variety of problems for the
maintenance staff from downed trees to
erosion along curb lines. However, the
storm that arrived early on August 13
tested the city's storm water system.
Heavy rainfall, amounting to just over five
inches in some areas, during the early
morning hours resulted in flooding in
many low -lying areas and streets as
creeks quickly reached and then
exceeded their capacity. City staff from

Streets, Parks Maintenance, Utilities,
and the Fire Department responded
along with residents to fill sandbags in
several areas to protect property from
the rising waters. Within a few hours,
the water began to recede and by
mid - afternoon, most of the flooded
areas had returned to normal as the
storm water system caught up in
moving the runoff through the
watershed. Streets crews completed
the final cleanup a few days later.
Filled sandbags used to hold back the
storm water have been saved and
❖ Tower Cleaning
Rain and condensation affect water towers by
creating an environment that collects dust and dirt.
After a few years, the underside of the tower bowl
begins to look a little shabby from the accumulation.
It can also lead to premature failure of the coating.
Recently, and as part of planned maintenance
program, the City had the exterior of North Park
water tower washed, cleaned, and inspected. The
process is fairly simple, requiring only pressure
washers and plenty of water to remove the grime.
In total, the contractor's crew spent about two days
working their way around the tower
from the top down. The result is a
tower that looks like it did when the
City painted it five years ago. Removal
of the dust and dirt also aids in
extending the longevity of the exterior
coating. Later in September, after the
peak water demand period is over the
tower will be drained, the interior will
be cleaned and inspected to ensure
that there are no problems with the
coating.
stored to shorten our response to another storm should they be needed.

❖ Culvert Repair
Over many years, storm water runoff from King
Park caused a culvert under Highview Avenue to
erode. The flared ends and adjacent sections
separated from the main body of the culvert
because of the erosion and it continued to damage
the area on either side of the roadway. Working
with a contractor, damaged sections of the culvert
were replaced and the culvert was brought up to
City engineering requirements that should
eliminate the need for similar repairs in the future
and the potential for a failure under the roadway.
