Grading Permits

A grading permit is required for any non-agricultural land disturbance. Land disturbance includes all activity that disturbs the root zone of existing vegetation (for example, clearing trees with a dozer requires a grading permit but clearing trees with a chainsaw does not). Construction of ponds is considered an agricultural activity unless the soil leaves the property (which would require a grading permit) or is located within a Special Flood Hazard Area (which would require a floodplain development permit). For a complete copy of the regulations, see the Greene County Stormwater Design Standards or contact the Environmental Section office at .

The following items must be submitted prior to issuance of a grading permit:

  1. Completed grading permit application signed by the property owner or their legally authorized agent.
  2. Grading permit fee. Checks must be made payable to Greene County Treasurer.
  3. An approved sediment and erosion control plan.
  4. Security Agreement, performance bond or other required security.
  5. Copy of the MDNR land disturbance permit for sites over 1 acre.
  6. Approved Storm Water Pollution Prevention Plan (SWPPP) for sites over 1 acre.
  7. Other State or Federal permits, if required.

Floodplain Development Permits

A floodplain development permit is required for any activity within the Special Flood Hazard Area (often referred to as the mapped floodplain) designated on the Flood Insurance Rate Maps for unincorporated Greene County. A floodplain development permit application must be submitted to the Environmental Section office along with plans for the proposed activity and the appropriate fee.

On-Site Wastewater Systems

On-site wastewater systems are commonly referred to as "septic systems" but include all systems not connected to public sewer. A permit is required for installation of a new system and for repair or replacement of an existing system. Permits may be obtained from the Building Regulations office located in Room 305 of the Historic Courthouse. For a complete copy of the regulations pertaining to on-site wastewater systems, see the On-Site Wasterwater Regulations & Standards or contact the Environmental Section office at .

In order to obtain a permit for construction of a new on-site wastewater system or for repair or replacement of an existing system, the following information must be submitted:

  1. Appropriate building permit application from Building Regulations
  2. Site Evaluation Form (Form EV01) and Soil Evaluation - Soil Factors Form (Form EV02) prepared by a qualified Soil Scientist.
  3. Site Plan and System Design prepared by a qualified Soil Scientist, Professional Engineer, Registered Sanitarian, or Geologist. All commercial, non-residential or mechanical systems must be designed by a Professional Engineer.

On-site wastewater system installers must be currently certified with Greene County and the Missouri Department of Health & Senior Services. Contact information for installers certified with Greene County are maintained by this office.
