§ 6-8. Screening/buffering.
Screening is used to reduce or hide the visual and noise impacts of non-residential uses on nearby residential and institutional land uses by using trees, shrubs, and other plant materials to materially hide the non-residential uses and to muffle the sounds that are generated by them. Buffering is used to reduce conflicts between and impacts on, adjoining land uses by separating them with a buffer yard or strip.
6-8.1. General screening requirements. In all cases where a residential use or district abuts any other use or zoning district, screening shall be provided in accordance with the requirements of section 6-8 and other pertinent provisions of this ordinance when the non-residential property is developed.
A.
When a non-residential use is developed adjacent to a residential or institutional use or district, a vegetative planting area that is at least 10 feet wide must be provided to materially screen, as determined by the Planning Director or designee, the principal and accessory structures and uses within the subject property from the view of abutting residential or institutional properties.
B.
When a non-residential use is developed across the street from a residential or institutional use or district, the vegetative planting area shall not be required in the front yard setback, except for a:
(1)
Parking area or lot with 5 or more parking spaces;
(2)
Side on corner setback of a corner lot (also known as the secondary front yard setback);
(3)
Outdoor storage;
(4)
Junkyard;
(5)
Mini-warehouse (storage units);
(6)
Boat storage area or facility; and
(7)
Salvage yard.
For those exceptions where screening is required in the front yard setback, all screening shall be as close as possible and practical to the non-residential use and extend no more than halfway to the right-of-way, except for any parking area or lot with 5 or more parking spaces. Such parking area or lot screening in the front yard setback shall use only species that generally do not grow to be taller than 3 feet.
C.
Lawns and other grassed areas shall not be included in calculating the width of the vegetative planting area. The vegetative planting area must be installed and be in compliance with the Zoning Ordinance before a Certificate of Occupancy can be granted.
D.
The vegetative planting area shall contain at least 2 groups of planted materials:
(1)
Group One: At least two off-set rows of evergreen shrubs shall be planted whose trunks are spaced not more than four feet apart at planting (measured side-to-side, as well as row-to-row), have a planted height of at least three feet, and are of such type that can be expected to be five feet or more in height after three growing seasons. The row that will be planted nearest to the land use being screened shall usually be planted between three and five feet from the land use.
(2)
Group Two: In addition, the vegetative planting area shall contain at least a separate row of shrubs that are dense, low-lying, continuous, and planted so as to visually fill-in the low-lying gaps between the trunks of the evergreen shrubs. In addition to the required Group One and Group Two plantings, the developer is encouraged to do more than the minimum and to utilize additional groups and rows of shrubs and/or trees, as appropriate for the land use being screened and the surrounding residential and/or institutional uses.
E.
The intent of these screening requirements is that the Planning Director or designee shall have complete flexibility in approving the placement and location of the Group One and Two plantings so as to materially screen the ground floor of the land use or land uses. Such flexibility shall include placement at the property line, near the use, and all points in-between the use and the property line.
Chain-link and other wire fences on non-residential property cannot be used to provide required screening, even when slat inserts are used.
Such screening is not required at access points to the property, such as entrances, exits, driveways and sidewalks. Screening planted near driveways, entrances, and exits intersecting with a roadway shall be planted so that the outside edge of the plantings is no closer than 15 feet to the intersection and shall be kept trimmed so that the outside edge of the plantings is no closer than 10 feet to the intersection. If a DOT driveway permit requires a sight triangle at a driveway, entrance, or exit, the portion of any required 15-foot vegetative planting area that would otherwise overlap the sight triangle shall be omitted.
F.
Maintenance of screening. All screening that is required by this ordinance shall be maintained in a healthy state by the property owner(s) so as to continue its effectiveness. Periodic inspections may be made to determine continued effectiveness of the required screening. Any deficiencies, if not addressed to the satisfaction of the Planning Director or designee, shall be treated as a violation of this ordinance.
Any shrub that is required screening that needs to be replaced due to an unhealthy state or because it has not grown to be five feet tall after three growing seasons shall be replaced within 30 (thirty) days of notification in writing by the Planning Director or designee. Any trees that are required screening that need to be replaced due to an unhealthy state shall be replaced within 180 (one hundred and eighty) days of notification in writing by the Planning Director or designee. If the unhealthy state is caused by a natural disaster (such as a hurricane, extreme drought, forest fire, etc.), the replacement period for shrubs and trees shall be doubled to 60 days and 360 days, respectively.
The replacement screening shall be of the same species or of similar effectiveness for screening, as determined by the Planning Director or designee, and shall be at least as tall as the two nearest plants or plantings in that group, tier, or row, as appropriate.
G.
When a vegetative planting area is deemed inappropriate by the Planning Director or designee due to site, neighborhood, or other conditions, the Planning Director or designee may allow either a durable masonry wall or privacy fence or any combination of walls, fences, and vegetation that are designed to be compatible with the character of adjacent properties, as determined by the Planning Director or designee.
H.
Walls and fences. For residential uses, walls and fences that are required by this ordinance must be at least five feet in height but shall not be greater than eight feet in height, measured from the ground along the common lot line of adjoining properties. For non-residential uses, walls and fences that are required by this ordinance must be at least five feet in height but shall not be greater than ten feet high. Walls and fences must be constructed and maintained in a safe and sound condition. Walls and fences near driveways and entrances and exits intersecting with a roadway shall be no closer than 10' to the intersection.
No fence or wall taller than 3 feet (whether required or not) may be located in the front yard setback or the side yard on street right-of-way setback.
When chain-link and other wire fences are installed on a non-residential property, they shall be screened by Group One plantings. Screening of other types of walls and fences on non-residential property is not required but plantings along them are encouraged, particularly along taller sections and longer stretches.
I.
Screening outdoor storage. Outdoor storage of any material, stocks, or equipment (other than junkyards and salvage yards), whether the outdoor storage is a principal use or an accessory use, on any lot within any district (other than a residential district or use) must be screened from any abutting residential use or district, in accordance with the requirements of this ordinance.
J.
Screening junkyards and salvage yards. Junkyards and salvage yards must be screened from public view from any public or private street and from any abutting lots in accordance with the requirements of section 1601.1 and other pertinent provisions of this ordinance.
K.
Waiver of screening requirements when screening is already provided. There may be cases where the unusual topography or elevation of a site, the size of the parcel involved, existing vegetation on the site, or the presence of screening on abutting property would make the strict adherence to the ordinance serve no useful purpose. In those cases, the Planning Director or designee is empowered to waive the requirements for some or all of the screening, as long as the spirit and intent of the ordinance and the general provisions of this ordinance pertaining to screening are adhered to.
L.
Vegetative requirements along shorelines of sounds, rivers, canals and other water bodies. Except when accessory structures are allowed in rear or side yards under other provisions of this ordinance, the minimum rear and side yards shall remain vegetated on waterfront lots. The vegetation shall consist of grass, trees, other planted ground cover, or remain in a natural state. Only the sides of the lot abutting the sound, river, canal or other water body shall comply with this requirement.
M.
Screening and trash receptacles. Dumpsters, trash compactors, and similar trash receptacles, whether located in a residential or non-residential development (other than a receptacle that serves just one single-family or two-family residence on the same premises), shall be enclosed on all four (4) sides, except that one of the four sides may have a 3-foot wide pass-through opening for persons to access the dumpster without having to open the dumpster gate. The trash receptacle shall be oriented so that the opening is visible to the fewest number of residences, whether the residences are on-site or off-site. Three (3) of the sides must be constructed of durable materials that match or complement the principal building. The fourth side shall be an opaque gate that latches securely to prevent it from inadvertently opening. The wall and gate shall have a minimum height of 8 (eight) feet. A chain link fence shall not be permitted for the wall or the gate.
6-8.2. General buffering requirements. Buffering is used to reduce conflicts between and impacts on, adjoining land uses by separating them with a grassed buffer yard or strip. The developer may substitute a landscaped buffer for the grassed one.
A.
When a non-residential property is developed adjacent to a:
(1)
Residential or institutional use or district, at least a 5-foot wide buffer yard or strip must be provided along all side property lines and at least a 15-foot wide buffer yard or strip must be provided along all rear property lines that abut that residential or institutional use or district.
The developer may elect to use a durable masonry wall or privacy fence that is at least 8 feet tall and is designed to be compatible with the character of adjacent properties. If the materials, height, and design are approved by the Planning Director or designee, the approved wall or fence may be used to substitute for up to 8 feet of the required 15-foot buffer yard or strip.
(2)
Public or private street, at least a 20-foot wide grassed buffer yard or strip must be provided along all property lines that abut or are a part of a public or private street.
B.
No fence or wall taller than 3 feet (whether required or not) may be located in the front yard setback or the side yard on street right-of-way setback. The required buffer yard or strip must be installed and be in compliance with the Zoning Ordinance before a Certificate of Occupancy can be granted.
C.
Maintenance of buffering. Any buffer yard or strip that is required by this ordinance shall be maintained in a healthy state by the property owner(s) so as to continue its effectiveness. Periodic inspections may be made to determine continued effectiveness of the required buffering. Any deficiencies, if not addressed to the satisfaction of the Planning Director or designee within 30 (thirty) days of notification in writing by the Planning Director or designee, shall be treated as a violation of this ordinance.
