The Environmental Division administers the County's Stormwater, sinkhole, erosion & sediment control, floodplain and on-site wastewater system regulations. This Division reviews proposed development plans and plats for compliance with environmental regulations, performs field inspections and provides information to developers, consultants and the general public regarding environmental issues.
A Grading Permit Application 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 Storm Water Design Standards
or contact the Environmental Division office at (417) 868-4147.
The following items must be submitted prior to issuance of a grading permit:
MS4 Permits are issued by the Missouri Department of Natural Resources to cities and counties under the National Pollutant Discharge Elimination System (NPDES) program of the federal Clean Water Act (CWA). The MS4 permit requires Greene County to develop a Stormwater Management Plan to reduce the discharge of pollutants from the stormwater collection system. Unlike wastewater, stormwater does not go to a treatment plant, but goes directly to streams and lakes. The Stormwater Management Plan describes the actions and activities implemented as part of Greene County’s Stormwater Program to reduce pollutants in stormwater and protect our lakes and streams.
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 must be submitted to the Environmental Division office along with plans for the proposed activity and the appropriate fee.
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 Wastewater Regulations & Standards or contact the Environmental
Division office at (417) 868-4147.
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:
On-site wastewater system installers must be currently certified with Greene County and the Missouri Department of Health & Senior Services . Contact information for County- Certified On-site Wastewater System Installers are maintained by this office.
