The Environmental Health Unit reviews properties for the purpose of approving the site for land divisions when onsite
water supplies and/or onsite sewage treatment systems will be used. Michigan Department of Environmental Quality promulgates
administrative rules (pdf)
regarding onsite water supply and onsite sewage treatment for a land division and subdivisions (R560.401 to R560.428).
Several criteria are used to determine the suitability of a parcel of land for division. Parcels are evaluated to determine if they are large enough to allow for the installation of both onsite sewage treatment systems and onsite water wells with the necessary isolation requirements. Soil evaluations determine the suitability of the parcel for onsite sewage treatment systems. Parcels with soil permeability above 60 minutes per inch or groundwater signs within 24 inches of the surface are not suitable for onsite sewage treatment, and the land division will be denied. Groundwater is evaluated to assure that a long-term drinking water supply can be sustained. Neighboring onsite water supplies and test wells are sampled for coliform bacteria, chloride, fluoride, hardness, iron, nitrate, nitrite, sodium, sulfate, and arsenic. Expanded testing for other parameters may be required due to proximity to known sites of contamination. Onsite water wells must also meet minimum yield criteria.
There are three different types of evaluations available at this office.
Subdivision or site condominium developments that are submitted by a licensed engineer or surveyor: A Subdivision Site Report form and all pertinent data are submitted to our office (in triplicate) with the appropriate fee in accordance with state law. Material submitted is reviewed for compliance with applicable rules and regulations. The Environmental Health Unit visits the property to confirm data submitted by the consultant. Any restrictions put on the onsite water supplies and/or onsite sewage treatment systems must be made part of the deed restrictions in the final plat recording. For detailed information on how to submit an application for a subdivision or site condominium, see the consultant's guide for submittal.
Land divisions less than one acre in size: A Land Division Application and all pertinent data are submitted to our office (in triplicate) with the appropriate fee in accordance with state law. Material submitted is reviewed for compliance with applicable rules and regulations. The Environmental Health Unit visits the property to confirm data submitted by the consultant. Any restrictions put on the onsite water supplies and/or onsite sewage treatment systems must be made part of the deed restrictions in the final land division recording.
Pre-Preliminary Evaluation: This evaluation is not required by state law or county regulation but is offered as a service to persons interested in developing a property. A developer or landowner often uses this service before purchasing a large parcel of land with intention to divide. An application form and all pertinent data that are identified on the application form must be submitted to our office with the appropriate fee. Environmental Health will review all data submitted and information in our records, conduct onsite inspections, and issue a written report. The report will contain a summary of the suitability of the property for onsite sewage treatment systems and/or onsite water supply systems.
