Drainage update 7/10/2017
Hearings or Meetings:
No upcoming meetings are scheduled as of this time.
(Lincoln Twp.) For the most part
this project is done. There are just a
few small clean up items to finish, but otherwise the major stuff is
finished. The contractor removed all
their large equipment last week. Seeding
and reshaping some areas was taking place late last week. A few final items to address with tile
hook-ups remain, then this project will be complete.
(Beauford Twp.) DMI finished midafternoon
on Friday, July 7, with the additional tile on this repair project. The site is graded and water is running
nicely in our newly installed tile.
Minus maybe a few clean up items to address, this project is also
(Garden City Twp.) This simple ditch
cleaning project has turned out to be more challenging than originally thought. The contractor is moving at
a slower pace due in part to the issues of debris in the ditch and very
saturated ditch banks. We have many
areas of ditch bank sloughing, but the extreme westerly side of Garden
City Township, where the ditch crosses into Lincoln Township, seems to be the
epicenter for the most slough issues.
The issue is very steep side slopes on the ditch banks and water weeping
through the ditch banks, making the soil on the side slopes very wet and highly
unstable. Normal slough repair methods
are not working, so we are trying a method we’ve used before on other
ditches. We are installing areas of “toe
drains”, basically a small tile that’s installed down at the level of
where the water is seeping out into the ditch.
These tiles are usually 4 or 6 inch tiles installed parallel with the
ditch. The reason for doing this method
is to catch the seeping water before it saturates the ditch bank anymore and
causes even more erosion. We have used
this “toe drain” system on other ditches with very similar issues and have had
very good results.
(Mankato Twp.) Fairly quiet at this
construction site lately. Things will
start to get busier soon as the Blue Earth County Highway Department has
awarded the CSAH 12 expansion project to a contractor. Our drainage ditch goes right under the road
that is getting expanded and redone.
When that new culvert is installed, that will make a huge difference in
the drainage of CD12. The new road
crossing will be installed at the proper legal ditch grade and then our
contractor can start with their ditch cleaning.
Things should move along fairly quickly once the new crossing is
This last week was a very busy week. Two of the three days we held landowner
meetings. In between preparing and
hosting landowner meetings, we still have multiple projects going on at the same
time. It’s a huge sense of relief to
have two of our major projects for the year done. CD28 and CD86 are both (for the most part)
finished, minus some very minor clean-up work.
CD28 (Lincoln Twp.) was a very large project that started in the spring
of 2016. This is not our largest
project ever, but it was one of the most challenging.
The challenges as many might know with Lincoln Township, besides 70
inches of rain in a season, are the extremely tough soil conditions. We had our share of challenges along the way
with this project, but the contractor did a great job of getting the new pipe
in and installed under tough working conditions most of the time.
The Blue Earth County Highway 12 extension project will be
starting shortly. This is near the Blue Earth County Justice Center and the newer
MNDOT building. I’ve seen the plans for
this highway project, and it will be a good size project with many challenging
aspects to it. This will be a great
relief to the current Highway 22 route through town. Mankato still seems to be expanding out that
way, with the new school and new subdivisions going in around the school. We in the drainage department look forward to
the start of the Highway 12 project.
One of our drainage ditches that is currently being repaired is
awaiting a new culvert on one of the crossings for the new highway.
We had three very productive landowner meetings last
week. There always seems to be issues
somewhere in the county with drainage.
We had some interesting weather in the last few days. Hot and humid turned to very windy, violent
and destructive storms Sunday night.
There are many photos and videos of the multiple tornadoes that came out
of the storms that made their way through Blue Earth County. I used to work up in the Winthrop, Minnesota
area and still have friends up there.
They got anywhere from golf ball sized hail to some reports of almost
softball size hail. Compared to last
year, locally we’ve been very fortunate as far as weather this year.
Not much else going on in the drainage world
at the moment, but a lot can happen in a one week.
Inspections – week of July 3 – July 7:
(Lincoln Twp.) Project site drop-ins
to check on progress of the project.
(Garden City Twp.) I just stop by
randomly three or more times a week to check on progress of the current repair
project and to address issues that may arise.
(Beauford Twp.) I tried to stop in a
couple times during the week randomly as DMI finished up the additional tile to
be replaced on this repair project.
Please call with issues you observe on our
public drainage system, as there is a lot of open ditch and tile in our county
and only two of us in the drainage department.
We will do our absolute best to service your issues and concerns as we
We require that all
repairs to a county drainage system (tile or open ditch) be authorized by one
us in the drainage office, either Craig or myself, before any repairs are made.
