Land Use Planning Department's primary function is to administer Onsite Wastewater (septic) and Land Use (zoning) ordinances and permitting services, as well as facilitating the AIS Prevention Program and participating in water planning initiatives throughout St. Louis County’s watersheds.
Land Use
The Land Use division is responsible for the administration and enforcement of land use regulations. This includes the comprehensive plan, zoning, land use permits, and the subdivision of property. The county has land use authority outside of all
municipal boundaries except in four
townships that have land use authority.
On-Site Wastewater
The On-Site Wastewater division administers the on-site wastewater permitting and regulation of individual subsurface sewage treatment systems (SSTS) and small community systems generating less than 10,000 gallons of wastewater per day. This includes oversight of Point of Sale Program intended to ensure that upon property transfer failing systems are upgraded to meet standards and administration of a septic loan and grant program.
