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

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

Redetermination

Including: • Process • Cost • Timeframe

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
