A riparian buffer corridor of a minimum of 100 feet in width shall be located adjacent to any stream, intermittent stream, closed depression if prone to wetness, identified sinkholes, and any other surface water areas, i.e., ponds and wetlands. The riparian buffer shall be measured starting from the edge of the defined stream bank, top of sinkhole/depression, and/or edge of pond embankment, wetland as the case may be. The 100 feet shall then be a distance of area measured perpendicularly from the edge. Within the buffer area impervious surfaces are prohibited except for driveway accessways and site stormwater management areas. The buffer area shall be landscaped with year-round ground cover at a minimum.
