SLIDE 2 Redetermination
- Background
- JD 18 SM completed redetermination in November of 2016
- Concerns with
- Outlet fee for JD 17 MS, paying over 9% of the benefits
- Watershed boundaries do not match up to those previously
redetermined
- CD 65 boundary was extended to include portions of JD 18 SM
- Redetermination stays in effect until
another redetermination is complete
- Total cost of the project was $1,033,395.89
- Cost less seeding and damages was
$92,167.32
SLIDE 3 Redetermination
- Proposed
- Do a redetermination on JD 18 SM, JD 17 MS, JD 32 SM, Sibley CD 65
- Upon completion they are combined into 1 large system
SLIDE 4 Redetermination
Including:
SLIDE 5 Redetermination
RECAP:
- Eliminates current outlet fees
- All 4 ditch systems, big or small, pay for the maintenance of the others
- All acres are part of the system and watershed boundaries become
seamless
- CD65 and JD 18 SM boundary would no longer be an issue
- Need to pay for the redetermination again
- Drainage authority would be realigned to reflect the new benefit
percentages
- All expenses incurred up until ROB is final are spread on current benefits
- Current debt on JD 18 SM is $647,637.50
