In addition to a review by Building and Zoning Services, a review by Columbus Public Health (CPH) is required for any lot split where a sewage treatment system will remain on a lot, no associated sanitary sewer plan is proposed, and/or potential buildable lots 5 acres or less in size will be created with no access to the sanitary sewer system.
The CPH Lot Split Review will:
- Assess any existing sewage treatment system(s) to ensure proper function.
- Establish that enough space remains on the lot(s) for replacement of existing sewage treatment system(s).
- Assign an area for the installation of sewage treatment system(s) on new lots.
- Make sure the split does not encroach on any required isolation distances.
