SCREENING AND BUFFERING
Certain land uses, because of their character and intensity, may create an adverse impact when developed adjacent to other less intensive land uses. The general purpose of this article is to establish guidelines to preserve the value and appearance of property in the county and to recognize that the transition between certain uses requires attention to protect less intensive land uses. The goal is to identify land use relationships that may be incompatible and to specify an appropriate buffer or screen in order to minimize adverse impacts.
(Ord. of 1-19-98, § X)
The buffering and screening shall be adequate to meet the intent of section 21-211, but shall not exceed one hundred twenty-five (125) percent of the length of the development activity required to install the buffer and screening, unless required on a site plan approved by the board of commissioners. The requirements of this article shall apply to the side and rear yard of the operational area except driveways, sediment ponds, and detention areas unless otherwise indicated herein.
(Ord. of 1-19-98, § X; Amend. of 9-6-11; Amend. of 9-3-19)
(a)
Generally. Buffers shall be required in accordance with the table in section 21-216 when any use is being developed abutting an existing developed lot, however less intensive uses locating next to more intensive uses shall not be required to comply with the screening portion of the requirements of this article. Where a conflict exists between the buffer requirements for a use and setback requirements for a zoning district, the use requirements shall control. The required buffer may not be used for loading, storage, or similar operational area needs that are either part of or accessory to the proposed use unless otherwise indicated herein.
(b)
Modification of buffer requirements. Buffer requirements may be modified in accordance with the provisions of section 21-217.
(c)
Responsibility for requirements. One hundred (100) percent of the applicable buffer requirements shall be the responsibility of the developing land use, unless expressly provided otherwise.
(d)
Standards for trees and shrubs. Required trees and shrubs shall meet the following standards:
(1)
All required large maturing trees shall have a minimum caliper of one and one-half (1½) inches measured six (6) inches above the proper planting level;
(2)
Shrubs shall be one (1) foot tall or taller when planted; and
(3)
All specifications for the measurement, quality, and installation of trees and shrubs shall be in accordance with the American Standards for Nursery Stock published by the American Association of Nurserymen, free of disease, and in otherwise sound and healthy condition.
(e)
Modification of planting types. If it is demonstrated that existing vegetation meets the intent of this section, the zoning administrator may waive the requirements for the plant material.
(f)
Maintenance of buffer. The owner of the property where the buffer or screening is shall be responsible for maintaining the buffer and all required plantings in good condition.
(g)
Buffering of expanded uses. Expansion of a use existing prior to the effective date of this chapter shall require the expanded portion of the facility to come into conformance with these requirements.
(h)
Watershed buffer areas required. A minimum 30-foot vegetative buffer for low density and 100-foot buffer for high density and SNIA development activities is required along all perennial waters indicated on the most recent versions of U.S.G.S. 1:24,000 (7.5 minute) scale topographic maps.
(i)
Development in required watershed overlay buffer areas. Development in the buffer area shall be limited to the following exceptions in conjunction with minimizing built-upon surface area, directing runoff away from surface waters and maximizing the utilization of stormwater best management practices:
(1)
Artificial streambank or shoreline stabilization;
(2)
Water dependent structures such as piers, docks, etc.;
(3)
Other structures such as flag poles, signs, and security lights which result in only minimal increases in impervious area;
(4)
Public projects such as road crossings and greenways where no practical alternative exists.

When it is impractical to plant required screening during optimal planting seasons, the owner of the property upon which the required screening is to be located may submit a letter of compliance to the zoning administrator. The letter will acknowledge that the owner of the subject property is aware of the applicable screening and buffering requirements and will meet these requirements within a specific date, but in no case more than one (1) year. Failure to comply with the provisions of this article by the time stated in the letter of compliance shall constitute a violation of the zoning ordinance.
(Ord. of 1-19-98, § X)
Screening shall be required along the side and rear property boundaries of the zoning lot.
