Latest version.

527.1. Landscape, Buffer, and Tree Preservation Ordinance Preface.

Purpose. The purpose of provisions is to preserve the county's natural environment, and to enhance the county's built environment. The Horry County Council hereby finds that the preservation of existing trees, the planting of new trees and other plant materials, and the provision of buffers between dissimilar uses as part of the land development process is a public purpose and provides for the public health and general welfare. Specifically, proper site design and management is widely recognized for its importance in the reduction of soil erosion, storm water runoff, noise, high wind speeds, and glare; providing shading and cooling; and contributing to the aesthetic and economic value of real property.

Applicability. The buffer and landscape sections of these provisions shall apply to parcels that are developing or redeveloping, in accordance with this subsection, within the unincorporated portion of Horry County. With the noted exception of live oak protections, the Tree Preservation section of these provisions shall apply to parcels within the unincorporated portion of Horry County which front along a roadway identified in Table 1. In addition, the Tree Preservation section of these provisions shall also apply to parcels within the unincorporated portion of Horry County which are separated from a roadway identified in Table 1 by an easement or right-of-way, or an amenity, utility, or common area parcel. The live oak protections stipulated in the Tree Preservation section shall apply to all parcels in unincorporated Horry County. Exemptions to these provisions are listed in section 527.1.D., exemptions.

Newly constructed development, buildings, structures, and vehicle use areas shall comply with the landscaping, buffering, and tree preservation provisions contained herein.

Renovation work which modifies or expands a structure or business whereby the improvements are equal to or greater than twenty-five (25) percent of the properties County's assessed value, or the value of the property as determined by an certified independent appraisal, shall comply with the Horry County landscape, buffer, and tree preservation provisions contained herein. The general maintenance and repair of existing structures or buildings are exempt from the standards established herein.

If an existing business is damaged or destroyed due to an act of nature (flood, hurricane, tornado, etc.), or catastrophic event and is reconstructed within twelve (12) months of such damage or destruction, the standards contained herein shall not apply. This exemption, however, shall not relieve the property owner of having to meet applicable building or zoning regulations that may be in place at the time of reconstruction.

Dumpsters and other similar waste receptacles shall be screened from the surrounding environs in accordance with section 515 of the Horry County Zoning Ordinance if any change to the building footprint (addition or deletion) of the existing buildings on the property is to be made.

Refer to specific overlay district (i.e. Socastee Overlay District, Hwy. 501 Overlay District) site design requirements as they apply to the land development process.

Planning Commission Review. In accordance with the Horry County Land Development Regulations, the Planning Commission shall review proposed landscape treatments for the following project types:

Major developments involving the creation of ten (10) or more lots/units (including the parent tract);

Group developments such as apartment, condominium, and townhouse complexes;

Any commercial, industrial, or office land development on a single tract or parcel of land that will produce an estimated five thousand (5,000) average daily trips (ADT's) according to trip generation rates established by the Institute of Transportation Engineers and established in the current issue of the ITE Trip Generation Manual.

Exemptions. The following land use activities shall be exempt from the provisions of landscape, buffer, and tree preservation provisions as described below.

Agricultural activities involving the continuous production of field crop, livestock, and evergreen and deciduous nursery stock commodities for profit. Refer to section 527.4C. concerning land disturbance permitting;

This exemption does not include applications for Major or Minor Subdivisions for which landscape buffers may be required.

Reserved.

Tee, green, and fairways associated with regulation golf courses and Par 3 golf courses, except where specimen trees, as identified in Table 3 abut a roadway identified in Table 1.

NOTES:

Buffers are not required between parcels where they are separated by platted road right-of-way.

Where developing/redeveloping nonresidential and multi-family vehicle use areas abut a residential zoning district not separated by a buffer strip at least twelve (12) feet in width, one (1) of the following buffer treatments shall be constructed and maintained between such parcels in accordance with section 527.3.

Contain a decorative privacy fence or wall, or a planted and stabilized earthen berm at least four (4) feet in height above the adjacent finished elevation of the subject vehicle use area. Side slopes on earthen berms not to exceed 1.5:1 ratio.

FOOTNOTES:

⁽¹⁾ Buffer Strip required except along platted road rights-of-way where landscape strip instead is required. Refer to section 527.2.

⁽²⁾ Buffer strip required to screen parking only. Refer to section 527.3

⁽³⁾ Landscape strip required. Refer to section 527.2

⁽⁴⁾ Landscape strip, not buffer strip required where multi-family (apartments/townhouses/condominiums) and associated vehicle use areas abut. Refer to section 527.1
