Drainage update 8/06/2019

  

Upcoming Drainage Hearings or Meetings:

  • Blue Earth County will be holding a landowner informational meeting on August 9, 2019, for CD35 (Mapleton Township).  Landowners affected by this meeting will be notified via mail.  The mailer will include details of times, location and meeting information.                                                                                                                                      

Project Updates:

   

  • CD48 (Cambria Twp.)  The contractor has been out doing a few check-list items that include putting some finishing touches on a few of the water quality intakes in the road right-of-way.
  • JD09 (Le Ray Twp.)  Nothing new to report from last week. 
  • JD34 (Le Ray Twp.)  A few final check-list items still remain for the contractor.    
  • JD51 Waseca (Danville Twp.)  All but a few small areas of buffer reseeding are done.  Cleaning is completed and new outlets installed where needed. 
  • CD28 (Lincoln Twp.)  With some drier weather lately, the contractor has been able to gain some ground on installing the new 24-inch HDPE tile.  This has been a challenging repair from the start: lots of rain, high water table in the soil, and sandy soils are all a mix for challenging a contractor.  Photo below of the new pipe being installed.cd28
                                                                                                                                                         

Drainage Minutes:

We are finally able to catch a break as far as the weather.  The recent drier spell has been much welcomed by some of our contractors.  We have only one major project going on at the moment,  CD28 in Lincoln Township.  We still have a fair number of repairs from this spring that need completing - hopefully by the end of the year.

Looking towards fall of this year, things will get very busy after harvest.  We will have a few major cleanings and reshaping projects going on.  Some possible tile replacements may occur on various drainage systems across the county. 

The recent trend is trying to repair tile on some of our old and failing drainage systems.  For some tile systems and branches this is an option, but for many it just doesn’t work.  Many times, the existing tile lines are too shallow and too small.  

As the drainage authority, we have to make a call.  The drainage authority has to act in the overall best interest of the drainage system.  If we receive notice of a large tile repair, we need to consider all the facts, including if it is going to serve the drainage system better as a repair or an improvement.  The past three years of wet conditions have definitely increased the number of large repairs and improvement projects in the county.

Over the next few weeks, I will try to navigate and explain to people the process the drainage authority goes through to determine if a project is a repair vs. an improvement.  I will try to explain the steps to both options and give some reasoning behind why one would be better than the other.  I'll try to explain why one option costs so much more than the other, both monetarily and time wise. 

Stay tuned in the next few weeks if you’re interested in learning more about this process.

Have a great week everyone and get out and enjoy the nice weather.                                                                                                                                                             

Recent Drainage Inspections – week of July 29 – August 2:

  • CD35 (Mapleton Twp.)  Despite removing some of the beaver and their dam, we still have another beaver dam.  A more thorough investigation might be needed.  
  • CD28 (Lincoln Twp.)  Drier weather this past week has helped make progress with the new tile install.  Conditions are still tough with wet soil conditions.
  • JD51 Was. (Danville Twp.)  Final buffer seeding should be finished as of today.
  • CD29 (Danville Twp.)  We had a contractor replace a portion of old clay tile line.  New tile is HDPE dual wall installed at same depth and location of old clay.
  • CD27 (Lincoln Twp.)  Hydro-seeding and all other seeding is done as of today.  The hydro-seeding from last week is already sprouting.  Things look nice and hopefully the new shelf area will serve us well going into the future.
  • JD09Bro (Cambria Twp.) JD36Bro (Cambria & Butternut Valley Twp.) JD48Bro (Butternut Valley Twp.)  We had a contractor start mowing some of the buffer areas along portions of these ditches.  Our contractor will continue on most of all the open ditches in the westerly and southerly townships of the county.  After mowing of these ditches is completed, the contractor will follow up with spraying for re-growth of weeds and brush.
  • JD36Bro (Butternut Valley Twp.)  We have a contractor trying to televise two portions of the old tile system.

Just as a friendly reminder with the grass buffer areas along our county ditches, we ask that people please do not place rocks or any debris that may damage our contractor’s mower or sprayer equipment in those areas.  We also ask that no equipment or permanent items be parked or left in this buffer area.  We are doing the mowing and spraying as part of maintenance and preserving the overall health of the ditch system.  Please call or email with questions or concerns.

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.
