Article 23 — Conservation Design Community
Purpose
It is the purpose of this ordinance to provide flexibility in ensuring preservation of greenspace within a master-planned residential development. A Conservation Design Community design preserves greenspace while maintaining the prorated density of residential units for the overall site area. Neutral density is achieved by allowing smaller individual-owned residential lots in neighborhoods that include or are adjacent to aesthetically and ecologically important areas. The goal of the design process is to identify and set aside conservation areas prior to the delineation of transportation and residential pod layouts. Greenspace areas include wetlands, stream buffer zones, woodlands, playing fields, and meadows, depending on the resources of the land.
The intent of the Conservation Design Community regulations is to:
and other features having conservation values, including views, vistas, and indigenous vegetation; and
General Regulations
Applicants utilizing the Conservation Design Community regulations shall comply with June 20, 2023 all other provisions of the Cherokee County Zoning Ordinance and all other applicable laws, except those that are incompatible with the provisions contained herein.
However, when a tract is held in multiple ownership, it shall be planned as a single development, and developed according to a single plan.
June 20, 2023
Notwithstanding the provisions noted above, a Conservation Design Community may have land that is less than thirty (30) acres if the Board of Commissioners, through a public hearing process in accordance with Section 18.3-3 and 18.3-5(A)(7) and upon showing by the applicant, is convinced that a Conservation Design Community is in the public interest because one or more of the following conditions exist:
Use Regulations
Land planned as a Conservation Design Community may be used for the following purposes:
Techniques to determine number of lots permitted.
Density Neutral.
The number of lots allowed shall be density neutral. “Density Neutral” is defined as follows.
The number of lots in a Conservation Design Community will not exceed the number of lots that can be reasonably created within a conventional subdivision at the same site location. The following techniques are provided for insuring comparability between a conventional development and conservation design community.
The resulting Adjusted Tract Acreage is then multiplied by the zoning district DUA (dwelling units per acre). (see Table 23-1)
Calculating Adjusted Tract Acreage
Net Constrained Land Acreage
Once the area of Constrained Lands has been calculated, the Adjusted Tract Acreage is calculated by subtracting the area of Net Constrained Lands from the Gross Tract Acreage of the property to be developed as a Conservation Design Community.
Gross Tract Acreage Net Constrained Land Acreage -Adjusted Tract Acreage
The number of lots allowed is determined by multiplying Adjusted Tract Acreage by the maximum of Dwelling Units per Acre. for the zoning district.

Conservation Community Design Standards
Greenspace.
"Greenspace" is defined as that portion of a tract set aside for the permanent protection of sensitive natural features, farmland, scenic views, and other unique features which may be accessible to the residents of the development and/ or the County.
Standards to Determine Greenspace.
Adjusted Tract Acreage
Primary Conservation Areas.
June 20, 2023
Secondary Conservation Areas.
Secondary Conservation areas are those areas within a property which contain other intrinsic qualities of value to the community. Secondary Conservation areas are valued as supplemental area to the total conservation area of a Conservation Design Community. To that end, Cherokee County requires Secondary Conservation Areas to be protected to the maximum extent possible after all identified Primary Conservation Areas have been protected.
RESERVED

Procedure
Pre-Application Meeting
A Pre-application meeting is required between the applicant, the site designer and the planning staff. The purpose of the Pre-Application Meeting is to introduce the applicant to the County’s zoning and subdivision regulations and procedures, to discuss the applicant’s objectives and to schedule site inspections, additional meetings, and plan submissions. Applicants must present the Existing Resources / Site Analysis Map at this meeting.
Existing Resource / Site Analysis Map
The purpose of the Existing Resources / Site Analysis Map is to familiarize County staff and officials with existing site conditions This map shall be provided prior to any site inspection and shall form the basis for the development design as shown on the Conceptual Preliminary plan.
The applicant shall prepare the Existing Resource / Site Analysis map, to ensure that the important site features have been adequately identified prior to the creation of the site design, and that the proposed Greenspace will meet the requirements of this article. The Existing Resource / Site Analysis map shall include the following features:
to and reviewed by the Director of Planning and Zoning or his/her designee prior to the submission of either a Sketch plan or a Concept / Preliminary Plan as described herein. If found inadequate by the reviewer, the reviewer shall provide in writing the reasons for its inadequacy, and the existing resources map shall not be accepted until adequate changes are made.
Site Inspection
After preparing the Existing Resources Map, applicants must arrange for a site inspection of the property by the Planning staff and other County officials and shall distribute copies of such site analysis plan at this on-site meeting. The purpose of the site visit is to familiarize staff with the property’s existing conditions and special features, to identify potential site design issues, and to provide an informal opportunity to discuss site design concepts, including the general layout of the designated Greenspace lands and potential locations for proposed buildings and street alignments. Comments made by staff shall be interpreted as being only suggestive. It shall be understood by all parties that no formal recommendations can be offered, and no official decisions can be made at the site inspection.
Sketch Plan Submission
A Purpose. A sketch plan shall be submitted as a diagrammatic basis for informal discussion with staff regarding the design of a proposed subdivision or land development. The purpose of a sketch plan submission is to provide a mechanism to help applicants and staff develop a better understanding of the property and to help establish an overall design approach that respects its special or noteworthy features while providing for the density permitted under the zoning ordinance.
B Sketch Plan information. To provide a full understanding of the site’s potential and to facilitate the most effective exchange with the planning staff and other officials, the sketch plan should include the information listed below. Many of these items can be taken from the Existing Resources / Site Analysis Map. The diagrammatic Sketch Plan may be prepared as a simple overlay sheet placed on top of the Existing Resources / Site Analysis Map.
June 20, 2023
Concept / Preliminary Plan
Preparation and submission of the Concept / Preliminary Plan shall follow the process and procedure outlined in Article 5.5-3 of the Cherokee County Zoning Ordinance. The Existing Resource / Site Analysis Map and Sketch Plat produced prior to the preparation of the Concept / Preliminary Plan shall be submitted with the Concept / Preliminary Plan.
Four Step Design Process
All Concept / Preliminary plans for Conservation design communities shall include documentation of a four step design process in determining the layout of proposed Greenspace lands, house sites, streets, and lot lines as described below. Each step shall be plainly demonstrated where combined together in one plan sheet. Step 1 below shall be demonstrated as a separate plan sheet within any Concept / Preliminary Plan.

Buffer requirement.
Where property to be developed as a Conservation Design Community abuts property not a part of the Conservation Design Community, the Conservation Design Community shall have a buffer along the exterior property boundary. The buffer shall be undisturbed except as specifically allowed herein, and of sufficient volume to provide a year round opaque screening. Where no vegetation exists within the required buffer area, or where existing vegetation does not provide a sufficient screen, and where planting of native vegetation will provide a screening meeting the requirements of this section, the buffer will be planted with such vegetation to meet the intent of this section.
All clearing associated with the construction of such path shall be contained within the 8 feet. If such trails are planned as a part of the development, the trails must be located within the first 25 % of the buffer furthest from the exterior boundary line for the subdivision but in no event shall be within 30 ft. of said exterior boundary line, unless abutting another greenspace.
Size of Buffer.
The size of the exterior buffer shall be a minimum of 50 ft. except, where the property planned as a Conservation Design Community is zoned R-20 or R-30 and is immediately adjacent to property zoned AG or R-80, the buffer shall be 75 ft.
Buffer counts toward Greenspace requirement.
exterior boundary buffer may be used to satisfy the minimum required Greenspace for the development. The buffer area shall not be included as a part of any platted residential lot within the subdivision. This buffer shall be considered a secondary conservation area unless a feature of the buffer qualifies as Primary Conservation area as defined herein. Such buffer shall be designated as part of the Greenspace for the subdivision and be permanently protected in accordance with the requirements contained herein.
