Soil Evaluation Requirements

To have a soil evaluation performed, you will need to complete the following items:

  • Prepare a boundary drawing of the property. The drawing must include property lines, easements and any neighboring wells or sewage systems within 150 feet of the proposed well or sewage system. An aerial photo of the property lines can substitute for the boundary drawing. These can be accessed and printed through the MapWashtenaw tool.
  • Submit a complete soil evaluation application to:
    Washtenaw County Environmental Health
    705 N Zeeb Road, P.O. Box 8645
    Ann Arbor, MI 48107 to 8645
    Phone: 734-222-3800
  • The application must include:
    • Completed application form
    • 10-digit parcel identification number
    • Boundary drawing
    • Survey, if available
    • Legal description of the property
    • Fee
  • Contact an excavating contractor and select a few tentative dates for the evaluation. The excavating contractor will dig test holes for the evaluation. Excavating contractors can be found in the yellow pages under "Excavating Contractors" or "Septic Tanks and Systems - Contractors and Dealers." Schedule the soil evaluation with the Sanitarian.
    Note: Prior to performing any excavation it is your or the excavators responsibility to determine the location of any buried utilities and utility easements on your site. Call Miss Dig at 811 or 800-482-7171 for this information. Keep in mind that it usually takes a few days for Miss Dig to mark your utility lines!
