3. Requirements:

a. There are three levels of bufferyard as de-

tailed to this Code section:

1) Type A is intended to provide landscape beautification and screening between developments. No barrier feature is required.

2) Type B is intended to provide buffering and screening to shield neighboring properties from adverse effects of adjacent parking lots and moderately incompatible land uses. A barrier feature providing solid screening from the ground to a minimum height of three feet is required.

3) Type C is intended to separate highly incompatible uses with a combination of space, dense vegetation and barriers. A barrier feature providing solid screening from ground to a minimum height of six feet is required.

4) Redevelopment situations.

b. Existing natural forested and natural undis-

turbed areas may be used as bufferyards in accordance with the following standards: 1) A natural bufferyard may be used along all property lines which require a buffer, however, a natural undisturbed bufferyard shall be located at least 25 feet from the street right-of-way.

2) Natural undisturbed bufferyard where used to meet a bufferyard requirement of this Code shall remain undisturbed during development and construction and shall remain undisturbed until such time as it is replaced with another bufferyard option.

3) Natural forested bufferyard, where used to meet the bufferyard requirement of this Code may be enhanced through trimming, brush removal and addition of trees, shrubs and other plantings. 4) A natural bufferyard shall possess the minimum width as shown on Exhibit B of this Code.

c. Open space may be used as bufferyards in

accordance with the following standards: 1) An open space bufferyard may be used along all property lines required to meet the Type A and Type B bufferyard requirements of Exhibit C except that where parking lot screening is required, the planted bufferyard shall be installed in accordance with one of the options outlined in Exhibit B;

2) An open space bufferyard shall possess the minimum widths as shown in Exhibit B in order to satisfy the requirements of this section.

d. Where used in combination with a bufferyard,

fences, walls, and berms shall comply with the following standards:

1) Berms: Minimum height — Two and one-half feet; minimum width to crest — one foot; maximum slope — three horizontal feet for each one foot vertical and planting area requires trees and shrubs shall be planted on the crest with remainder of crest and side slopes shall be planted with groundcover and/or sod;

2) Fences: Fences used as a barrier feature in a required bufferyard shall consist of concrete, natural finished wood, maintenance-free vinyl or a combination shall be solid and of a two-sided design;

3) Walls: Walls used as a barrier feature in a required bufferyard shall be constructed of solid masonry finished on both sides. Finish may consist of stucco, brick, stone, versa-lock and other materials as approved by the city engineer with a minimum of six inches thick. Unfinished concrete block is not permitted. The wall shall be located within three feet of the property line.

5) Back-to-back requirement: Nothing in this Code shall require the "back-toback" placement of fences or walls where an existing fence or wall on an adjoining property substantially meets the requirements of this section. An existing, solid fence which meets all the above requirements, except for type, may be substituted for the required wall provided the width of the landscape strip is increased such that at the time of development approval an equivalent amount of buffering between properties is provided.
