What is a Day of Review?

Several times a year, the Office of the Water Resources Commissioner holds Days of Review (DOR) of Apportionments and/or District Boundaries for selected County Drainage Districts.  A DOR is an opportunity for the public to review the apportionments (or percent of total) levied onto individual parcels within the District.

Some reasons to hold a DOR include:

  • District hasn't been assessed for drain maintenance costs in over 10 years.
  • District has never been assessed (typically for newer developments)
  • Drain construction project within District; DOR prior to a multi-year debt roll commitment
  • District boundary has been updated
  1. Apportionment
  2. District Boundaries
  3. Appeal

Apportionments are determined in the following way:

At-Large (Municipalities' Apportionments)

  • Michigan Department of Transportation (MDOT) for benefit to state highways and state-owned railways, based on Michigan Public Act 51, as amended, a part of Michigan Transportation Law.  This uses acreage and predetermined coefficients per surface type (pavement, gravel, sidewalks, grassy/other) 
  • Washtenaw County Road Commission (WCRC), for benefit to county roads, same as MDOT 
  • City/Village Streets (same as MDOT)
  • Townships and Cities, based on development ratio of District
  • Railroads
  • Each of these percentages is subtracted from the total, which leaves the overall percentage to levy on privately owned parcels

Property Owners' Apportionments

  • Acreage of the parcel within the District; common area acreage within developments is spread evenly amongst the parcels within that development.
  • Property class of parcel is used as a proxy for land use and a coefficient is applied.  We use these property class divisions:
    • Agricultural
    • Residential
    • Commercial
    • Industrial
    • Exempt applies to government parcels currently in public use (examples include parks, public schools, municipality city and township halls; DNR properties); cemeteries, authorities
    • Parcels that are exempt from property taxes are NOT exempt from special assessments (churches, private schools, non-profit organizations)

Proceedings conducted at these public meetings are subject to the provisions of the Michigan Open Meetings Act.
