1. B.1 – Low Screen Buffer. This buffer is intended for areas where a limited buffer screen is required to separate uses that are potentially incompatible. This buffer is composed of live ground cover through out the buffer and trees planted every thirty feet along the length of the buffer.

2. B.2 – Medium Screen Buffer. This buffer is intended for areas where a moderate buffer is needed to separate incompatible uses. This buffer is composed of live ground cover through out the buffer, evergreen shrubs which reach a minimum of two to four feet in height and trees planted every thirty feet along the length of the buffer.

3. B.3 – High Screen Buffer. This buffer is used where a high degree of visual screening is required between incompatible uses. This buffer consists of a fully site obscuring fence with landscaping between the fence and the property line composed of live ground cover through out the buffer, evergreen shrubs which reach a minimum of six feet in height and trees planted every thirty feet along the length of the buffer.
