The illustrations in the Appendix1 graphically indicate the specifications of each bufferyard. Bufferyard requirements are stated in terms of the width of the bufferyard and the number of plant units required per one hundred (100) linear feet of bufferyard. The requirements of a bufferyard may be satisfied by any of the options thereof illustrated. The plant unit multiplier is a factor by which the basic number of plant materials required for a given bufferyard is determined given a change in the width of that yard. The type and quantity of plant materials required by each bufferyard and each bufferyard option are specified in this section. Only those plant materials capable of fulfilling the intended function shall satisfy the requirements of this chapter.
The options within any bufferyard are designed to be equivalent in terms of their effectiveness in eliminating the impact of adjoining uses. Cost equivalence between options was attempted where possible. Generally, the plant materials which are identified as acceptable are determined by the type(s) of soil present on the site. The illustrations have mathematically rounded the number of plant units required for each option with a given bufferyard. In actual practice, mathematical rounding would be applied to the total amount of plant material required by a bufferyard, not to each one-hundred-foot length of bufferyard. All of the illustrations are drawn to scale and depict the bufferyard according to the average project diameter of plant materials at five (5) years after planting.
Each illustration depicts the total bufferyard located between two (2) uses.
Whenever a wall, fence, or berm is required within a bufferyard, these are shown as structure required@ in the following illustrations, wherein their respective, specifications are also shown. All required structures shall be the responsibility of the higher intensity use. Whenever a wall is required in addition to a berm, the wall shall be located between the berm and the higher intensity use in order to provide maximum sound absorption.
