Repair V.S. Improvement (4):

Episode number four of “Repair versus Improvement.”  Last week I left off an improvement petition that was found to be valid.  We discussed that we have presented the petition to the drainage authority board and appointed an engineer for the improvement project.

Now, we order the engineer to do a preliminary survey report, which are also referred to as preliminary engineer reports (PERs).  The report from the engineer will provide details of current pipe sizes and drainage coefficients as well as open ditch capacities.  The report also outlines current issues with the drainage system and the proposed plan for improvement from the petitioners.  The report discusses the improvement details including the planned route, planned sizes and coefficients of new tile, along with proposed new structures, such as ponds, that might be added as part of the improvement. The report also includes approximate costs for the improvement project.   

The preliminary report is usually the point when landowners provide final input or  propose changes to the improvement project.  Once the report from the engineer is complete, the drainage authority board will hold an official hearing. 

The hearing, which is the first of three hearings, is to formally present and discuss the Preliminary Survey Report from the engineer.  The hearing is open to the public and provides landowners the opportunity to discuss the proposal and express any concerns they might have.  The engineer will also discuss the costs of the project with the drainage authority. The project will be reviewed to determine if it is feasible and cost effective.

If the report is approved by the drainage authority, the project is then ordered to continue moving forward through the improvement process.  As part of this first preliminary hearing, viewers will be appointed to make a new determination of benefits for the improvement.  The engineer for the project will also be ordered to start making a final engineer report.  This is where I will leave off for this week.     

Recent Drainage Inspections – week of August 26 – August 30:

  • CD28 (Lincoln Twp.)  Mowing has been completed for the most part.
  • JD82 (Pleasant Mound Twp.)  Mowing of the open ditch area has been started and should be finished up this week.
  • CD35 (Mapleton Twp.)  Monitoring on-going issues with bank erosion problems along with an active beaver situation.  
  • CD28 (Lincoln Twp.)  The recent nice weather conditions are helping crews make great gains on finishing this repair.  Crews finished the main line last week and hopefully finished branch number six over the past weekend.  Around 2,000 feet of branch seven, a 12-inch line, remains for this repair.  Shown below - crews installing final portions of branch six.cd28 branch 6
  • JD15 (Lincoln Twp.)  Some left-over repairs from this past spring are on our list for completion soon.  We have some contractors that are seeing some free time from now until harvest to get more repair work completed.  We had multiple sink hole areas along a portion of tile on this system.
  • CD56 (Lincoln Twp.) Inspecting areas of on-going slough issues.

Mowing and spraying of some of open ditch drainage systems is currently going on.  We have a contractor that is just about done with mowing and will start spraying for weeds and brush this week.  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.  We also ask that no equipment or permanent items be parked or left in this buffer area.  We are completing the mowing and spraying as 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.
