Site Development Rules

The Drain Commissioner has published Site Development Rules for the review and approval of storm water management systems proposed for new and redevelopments. These rules shall be followed in the processing of all subdivision plats, and all other land developments (such as condominiums, planned unit developments, manufactured housing communities, and other residential, commercial, industrial, or institutional developments) which impact established county or intercounty drains, or for which the Drain Commissioner provides support to other state, county, or local reviewing agencies. The following development activities are exempt from these standards:

  • Construction of individual single and two-family residential structures.
  • Additions or modifications to existing single and two-family residential structures.
  • Parcel divisions along an existing county road (no common private drives).
