CITY COUNCIL AGENDA REPORT
MEETING DATE: July 16, 2001
AGENDA #: 8A
PREPARED BY: Bud Osmundson, Director of Public Works
AGENDA ITEM: CONSIDER APPROVAL OF CONSTRUCTION OF A DRAINAGE SWALE AND
EXTRAORDINARY SNOW PLOWING AT 4585 PLEASANT STREET (Elmer
and Della Klingberg).
DISCUSSION: Historv: At the May 21, 2001 City Council forum, Mr. Lee Klingberg advised the
City Council of a drainage problem at his parents home, Mr. Elmer and Della
Klingberg, at 4585 Pleasant Street. Staff was requested to provide a report to the
City Council on what could be done to provide a solution to the problem.
ISSUES:
At the June 18, 2001 City Council meeting this item was deferred to allow all
parties to be present. Based upon discussions with the Klingbergs at that time,
Mr. Klingberg is asking for the letter from the City to assure that plowing will
continue in perpetuity. The City Attorney has recommended against such a letter
and that has been communicated to the Klingbergs. Elmer and Della appear to
be comfortable with a third option identified below. However, Lee continues to
insist on the letter. Lee has also raised the issue of access to our lift station. The
City has an access easement to the lift station.
The home is located on the south side of Pleasant which is an east/west street,
two blocks south of CSAH 21. The Klingberg home is 450 feet east of Duluth
Avenue and 650 feet west of Main Street. The street grade is relatively flat
immediately in front of the house and to the west, with a two percent grade to the
high point approximately 600 feet east. The home is about 0.5 feet lower than the
sidewalk adjacent to Pleasant, and the crown of the street is about one foot
higher than the house. Using survey equipment, Engineering Department
personnel shot elevations at the house, which are shown on the attached
drawing.
The drainage problem occurs in the spring of the year and is caused by snow in
the street gutter damming the runoff from the east, causing the runoff to flow
south on the Klingberg driveway. The house side or back of the sidewalk is only
0.2 feet higher than the street gutter line, so that when the snow from plowing is
piled 4 to 5 feet out into the street to the west. There is not any storm drain catch
basins or piping in the street. Being on the south side of the street, the snow piles
do not melt off like they do on the north side, which attributes to the drainage
problem.
This past March during the snowmelt, the Klingbergs called the Mayor, who
called me, and maintenance personnel opened up the snow dam with a loader

which allowed the runoff to flow down the gutter line and not the driveway. You
may remember that this last snow season had near record amounts of snow and
it was quite high and wide in front of the Klingberg residence.
The Klingbergs are looking for a permanent solution to prevent problems
occurring in the future. Mr. Lee Klingberg on behalf of his parents, requested that
the City provide a letter guaranteeing that the City would clear snow from the
street and sidewalk from the Klingberg house to Duluth. I visited the site and
discussed several options with the Klingbergs.
Option #1 was to reconstruct the sidewalk to a higher elevation so that the
drainage would have to flow down the street and not toward the Klingberg home.
This option is not very feasible due to the reconstruction of several concrete
driveways that would be required and all the grading of front yards that would
have to be completed.
Option #2 would be to install storm drain piping from the catch basin at the
intersection with Duluth to a new catch basin on the east side of the Klingberg
driveway. The idea would be to intercept the snowmelt runoff prior to running
down the driveway. This option would be expensive and may not work when the
catch basin is frozen over, which could occur.
Option #3, the option we agreed upon, was to construct a swale in front of the
Klingberg home, forcing the water down the driveway on the east side, plus
removing the snow from the street gutter line when it is piled high. This will
include the removal of two shrubs and some of the two-foot wide sidewalk on the
property. We would re-grade this area, plant two new shrubs, and sod when
finished. This also will include the construction of about twelve feet of sidewalk
from the existing sidewalk to the driveway. We would accomplish this work with
City personnel, but contract out the sidewalk installation. The total out of pocket
expense will be less than $500.
The snow removal in the gutter line in front of the Klingbergs should be extended
westerly at least past the funeral home next door. This part of Pleasant has a lot
of traffic due in part to the funeral home and St. Michaels Church and School. We
would not have to remove this snow immediately after a snowfall, but would
come back to cleanup the area a couple of days after snowplowing is complete.
We estimate that it will only take 15 to 20 minutes to do this snow removal, two or
three times a season.
I would recommend that the expenses for the swale construction be paid out of
the street operating fund, budget number 43100. The added snow removal costs
are small when compared to the capital costs of other alternatives. In twenty or
thirty years when the street is reconstructed, a deep catch basin draining to the
wetland to the south may be a viable permanent solution. However, at this time
Options #1 and #2 would be very expensive, estimated at more than $20,000.
(1) Approve a motion authorizing staff to construct a swale on the Klingberg
residence and to pay expenses out of the street operating fund and to
remove snow from the area as needed.
