The purpose of the following requirements is to enhance the health, safety, and welfare of McClellanville citizens by: protecting the integrity of existing properties from changes wrought by more intense development; ameliorating negative impacts of land uses on adjacent properties such as excessive noise, glare, and visual intrusion; and enhancing the natural drainage of storm water through provision of additional pervious natural buffer areas.
It is the intent of the Town, through these requirements, to promote quality development by enabling flexibility in site design, as well as to encourage the provision of imaginative and attractive vegetative screening that softens the transition between incompatible land uses. The provisions of this section are further intended to complement the requirements of Article VI (Tree Preservation) of this Ordinance
§7.1.1 Screening and Buffers
Screening and buffers shall be provided wherever the following are established within the Town of McClellanville:
(a) VC, HC or MD uses abutting, adjacent to, or separated by a right-of-way of sixty (60) or fewer feet in width from an existing property zoned for residential purposes ;
(b) Utility substations, not including electrical transmission and distribution lines and their right-of-ways
(c) Dumpsters; and
(d) Loading and outdoor storage areas.
§7.1.2 Accessory Uses
The Zoning Administrator or designee may require the provision of buffer areas and screening, including the installation of fences, for proposed accessory uses where deemed necessary to protect an abutting or adjacent principal or accessory use, upon a finding that the proposed accessory use is incompatible due to the potential for noise, glare, odor or visual impact to the existing and abutting principal or accessory use.
Where buffers or screening are required, either pursuant to the terms of this ordinance, or by virtue of such a finding by the Zoning Administrator, the developer shall provide such in accord with the following requirements:
§7.2.1 Requirements by Type
§7.2.2 Buffer Standards
(a) Buffers shall be measured from the property line, inward.
(b) Small and large trees shall be planted no more than ten (10) feet and twenty (20) feet, respectively, from the buffer yard perimeter.
(c) Driveways may traverse required buffers, but no parking or other structures shall be sited in the buffer area.
(d) A buffer width may be reduced five (5) feet with the installation of a substantially opaque wall or fence, at least six (6) feet in height.
It is not the intent of this section to create buffer areas where these requirements are shown to be inappropriate or excessive with reference to the overall depth of an existing parcel or where there exists an opaque and continuous buffer of natural vegetation proposed for retention, where fencing is provided no less than four (4) feet in height, or where the property is adjacent to undevelopable land area a minimum of 300¢ in depth, the Zoning Administrator may allow reduction of the average buffer depth by as much as thirty percent (30%), provided such reduction does not result in the proposed development providing a buffer which is substantially less in depth than that of adjacent or facing developments.
§7.4.1 Tree Preservation
(a) Nothing herein shall be deemed to preclude or be substituted for compliance with Article VI of this Ordinance.
(b) Trees retained in accordance with Article VI may be utilized in full or partial fulfillment of the requirements of this Article, upon approval by the Zoning Administrator. Such use, however, shall not alone constitute compliance with provisions of this section unless approved by the Zoning Administrator.
(c) Whether the requirements of this Article conflict with those or Article VI, the more restrictive of the two shall apply.
§7.4.2 Utility Easements
(a) In cases where drainage or other utility easements are provided along property lines and prevent location of screening elements and buffer areas, the minimum width of the buffer area shall be measured from the innermost edge of that easement inward.
(b) Upon approval of the entity owning the easement and the Zoning Administrator, all or a portion of the drainage easement maybe utilized as a buffer area and/or contain screening elements.
(c) Where all or part of such drainage easements are authorized as buffer area, the owner of such easement shall not be held in any responsible for removal of or damage to screening elements occurring with periodic maintenance operations.
(d) Use of private or public utility easements or public drainage easements for buffer areas and screening elements will require written authorization of the easement holder, with copies thereof being submitted to the Zoning Administrator prior to review of any screening plan.
When screening or buffering is required, a plan shall accompany any application for a zoning or building permit. Such plan, drawn to scale in conjunction with the required site development plan, shall include the following:
(a) Names and types of proposed land uses, with addresses and tax reference numbers;
(b) Existing land uses abutting the subject property;
(c) Location of existing buildings, parking areas, and other improvements on site;
(d) Location of buffer areas, indicating widths;
(e) Location, species and circumferences of existing trees to be retained in the screening or buffer areas;
(f) Schedule of screening proposed to be planted, including location, species caliper, and height quantities of trees, shrubs and other landscape materials;
(g) Location, height, design and construction details for fences or walls;
(h) Tree protection plan, where applicable;
(i) Tree and landscape planting details;
(j) Location and width of existing or required drainage easements, along with points of access for maintenance, as approved by the applicable agency responsible for such easements;
(k) Approval letters or encroachment permits from the easement holder, where buffer areas or landscape elements are to be located in drainage or utility or other easements.
The following standards apply to the selection, installation and maintenance of all screening and buffer materials required by the provisions of this Article:
