- CONSERVATION DESIGN COMMUNITY9
Editor's note—Ord. No. 2019-O-019, § 1, adopted Dec. 3, 2019, amended Art. 23, in effect deleting Art. 23 and enacting a new Art. 23 to read as set out herein. Former Art. 23 pertained to similar subject matter and derived from Ord. No. 2005-Z-001, adopted Apr. 19, 2005; Ord. No. 2009-Z-001, adopted Sept. 15, 2009; and Ord. No. 2014-O-001, Exh. A, adopted Aug. 19, 2014.
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:
1.
Preserve significant areas of land for ecological, recreational, and agricultural purposes in perpetuity;
2.
Encourage more efficient development of land consistent with public health, safety, and general welfare;
3.
Afford greater flexibility of design and placement of buildings and structures;
4.
Preserve and protect exceptional terrain, natural beauty, and sites of historic interest from inconsequential placement of homes, roadways, utilities, and appurtenances;
5.
Preserve the Etowah River and its streams and tributaries as natural resources;
6.
Prevent flooding, erosion, and water pollution, and protect the quality and quantity of drinking water;
7.
Preserve wetlands, aquifers, topographical, or soil features, marine and wildlife habitat; and other features having conservation values, including views, vistas, and indigenous vegetation; and
8.
Promote a less sprawling form of development (within the site of development).
(Ord. No. 2019-O-019, § 1, 12-3-19)
A.
Applicability of regulations. In order to achieve the purposes described in section 23.1, the conservation design community is available as a use in the single-family residential and agricultural (AG, R-80, R-60, R-40, R-30, R-20) zoning districts. Any property rezoned after December 3, 2019 upon which the property owner proposes a conservation design community, said plan must be approved by the board of commissioners. However, if the zoning of the property was established prior to December 3, 2019 a property owner may prepare a conservation design community plan according to the provisions of this article to be approved administratively. Applicants utilizing the conservation design community regulations shall comply with all other provisions of the Cherokee County Zoning Ordinance and all other applicable laws, except those that are incompatible with the provisions contained herein.
1.
Conservation design community plan approval in AG and R-80: The board of commissioners shall approve a site plan for a conservation design community on property zoned AG or R-80 in accordance with the following:
i.
Prior to submitting a complete application to the county for review, the applicant shall host a community information and input meeting and provide a meeting summary and sign-in sheet, as outlined in article 18.3-5 of the Cherokee County Zoning Ordinance, and a list of participants to such meeting shall be submitted to the county.
ii.
Once a community input and information meeting has been conducted, a complete application shall be submitted to the county. A complete application shall follow all requirements outlined in this article.
iii.
The applicant shall post notice on the subject property announcing an application for a conservation design community has been received by the county for consideration. the sign shall be posted no less than 30 calendar days prior to the site plan review by the board of commissioners.
iv.
A 30 day "public comment" period shall be required after receipt by the county of the complete application and notice has been posted on the property. All parties wishing to comment shall submit their comments to the county.
v.
Upon the expiration of the public comment period, the county shall place the application for a conservation design community on the next available agenda of the board of commissioners. At their meeting, the board of commissioners shall consider approval of the site plan. The board of commissioners shall approve a site plan upon finding the proposed subdivision meets the purpose of a conservation design community per section 23.1 of the zoning ordinance.
B.
Ownership of development site. The tract of land to be designed as a conservation design community may be held in single ownership or in multiple ownership. However, when a tract is held in multiple ownership, it shall be planned as a single development, and developed according to a single plan.
1.
Phased development: Unless approved under a concept/preliminary plan as outlined herein, each phase of a conservation design community must meet the density criteria established herein and may not exceed the density for the zoning district.
2.
Proof of ownership: The developer of a conservation design community must provide documentation of ownership of all land to be developed as a conservation design community prior to approval of a land disturbance permit for the development. Only lands that may be considered for development as a conservation design community are those lands owned by the applicant for the land disturbance permit.
C.
Site suitability. As evidenced by the existing resources/site analysis map, the conservation design community concept/preliminary plan, and the final plat, the tract incorporating the conservation design community shall be suitable for supporting development in terms of environmental conditions, size, and configuration as determined herein.
D.
Sensitive area disturbance. The proposed design shall minimize disturbance of environmentally sensitive areas, as shown on the existing resources/site analysis map. Lands within the 100-year floodplain, designated as wetlands, having slopes in excess of 35 percent, and riparian buffers adjacent to streams constitute such environmentally sensitive areas. Demonstration by the applicant that these features shall be protected by the proposed application shall be prerequisite to consideration and approval of the conservation design community concept/preliminary plan and subsequent final plat.
E.
Minor subdivisions prohibited. Minor subdivisions, whereby an original tract of land may be divided into not more than five individual tracts, are not eligible to be developed per the conservation regulations contained herein. Only major subdivisions, those subdivisions of land resulting in the creation of six or more lots, are permissible to be developed according to the Conservation Design Community regulations outlined in this article.
F.
Effect of concept/preliminary plan. Approval of the concept/preliminary plan shall bind all land within the plan to the requirements and conditions of the conservation design community regulations. Should the developer or land owner subsequently sell or otherwise transfer their interest in the property, all heirs and assigns shall be bound to the approved concept/preliminary plan, unless amended by and/or approved by the board of commissioners.
G.
Size of a conservation design community. A tract of land to be developed as a conservation design community shall contain not less than 30 contiguous acres and be of a configuration that is conducive to a conservation design community. The simultaneous planning of larger and adjacent parcels is encouraged.
Notwithstanding the provisions noted above, a conservation design community may have land that is less than 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:
1.
The property is adjacent to or across a street from property that has been developed as a conservation design community, and a conservation design community will contribute to the maintenance of the character, amenities, and conservation values of the neighboring conservation design community; or
2.
The property immediately adjoins and proposes to extend the greenspace from an adjoining conservation design community through the subject property and create a larger area of greenspace; or
3.
The property immediately adjoins a publicly designated "greenway" and proposes to extend the "greenway" through the subject property; or
4.
At the discretion of the board of commissioners, the development of a property as a conservation design community on less than 30 contiguous acres would be in the public interest.
(Ord. No. 2019-O-019, § 1, 12-3-19; Res. No. 2023-R-049, Exh. A, 6-20-23)

(Ord. No. 2019-O-019, § 1, 12-3-19)
23.4-1. 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.
1.
Method 1 - Yield Plan. Prepare a plan that demonstrates the maximum number of lots for a conventional subdivision on the site. The conventional plan does not have to meet formal requirements for a site design plan, but must address the site features and all applicable regulations, including storm water and development regulations. The conventional subdivision plan must be reviewed by county staff, prior to submitting a preliminary plan for a conservation design community to assess whether such plan meets the requirements for a conventional design.
i.
Yield plans must be prepared in accordance with subdivision regulations, and show proposed lots, streets, rights-of-way, and other pertinent features. The plan must reflect federal, state or local restrictions on building within and/or disturbance of wetlands, floodplains, steep slopes, existing easements or encumbrances, and if using septic, the suitability of soils for sewage disposal.
ii.
Yield plans shall reflect the dimensional standards for lots based on zoning district requirements, ie. Lot area, lot width, building setbacks, etc.
iii.
Where site is not served by sewer, the density shall be determined by evaluating the number of homes that could be served by individual on-site sewage management systems on conventional lots.
iv.
Yield plan must identify the primary and secondary site resources, and demonstrate that such primary resources can remain undisturbed, by allocating these areas to proposed lots.
v.
No more than 25 percent of the lot area of any individual lot may be within the 100-year floodplain or any body of water.
vi.
Road right-of-way on a yield plan shall use a minimum of a 50 foot width. Lot lines shall begin at edge of 50 foot ROW.
2.
Method 2-Adjusted tract acreage. Determine the area of constrained lands as defined in section 23.4-2, make adjustments in accordance with section 23.4-2.1 and subtract the net constrained land acreage from the gross tract acreage. The resulting adjusted tract acreage is then multiplied by the zoning district DUA (dwelling units per acre). (see Table 23-1)
3.
The greater number of lots calculated by either method (1) or method (2) is the "maximum allowed lots" in the conservation design community.
23.4-2. Calculating adjusted tract acreage.
1.
Determine the area of constrained lands.
Net Constrained Lands = Area of land in items a-e multiplied by 0.50, plus 100 percent of area of land in items f—g below.
a.
Slopes steeper than 35 percent that have an extent of at least 5,000 square feet of contiguous area.
b.
The 100-year floodplain.
c.
Jurisdictional wetlands as defined by the Army Corps of Engineers pursuant to the Clean Water Act.
d.
State waters.
e.
Area of land in stream buffers as required by federal, state or local regulations that are beyond the limits of items b. and c. above.
f.
Area of land designated for construction of permanent roads and associated ROW.
g.
Area of all impervious surfaces associated with amenities, including but not limited to parking areas, tennis courts, swimming pools, clubhouses and other similar amenities.
2.
Adjusted tract 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.
3.
Allowed lots by conservation design community:
The number of lots allowed is determined by multiplying adjusted tract acreage by the maximum of dwelling units per acre for the zoning district.
4.
Lot sizes.
In a conservation design community, up to ten percent of the lot total may be platted less than the average lot size but not less than the minimum lot size in Table 23-1. The lot size for all other lots must be at least the average lot size for the corresponding zoning district in accordance with Table 23-1. The average size of all lots within a conservation design community must meet or exceed the average lot size in Table 23-1 for the corresponding zoning district. There is no maximum lot size.
Table 23-1: Conservation Design Community Density and Lot Size Requirements
23.4-3 Area and yard requirements; locations and structures.
23.4-3.1 Placement. The placement of all principal buildings shall provide for safe, quiet, and harmonious grouping as well as adequate privacy by providing adequate front, side, and rear yards as shown in Table 23-2.
a.
There shall be a minimum building separation requirement of 15 feet between structures on adjacent lots. At no time shall any building be constructed where the setback from a side property line is less than the width of the eaves of the structure or five feet whichever is greater.
Table 23-2: Conservation Design Community Setback Requirements
(Ord. No. 2019-O-019, § 1, 12-3-19)
A.
House lots shall not encroach upon primary conservation areas, and their layout shall respect secondary conservation areas, as described herein.
B.
Views of house lots from exterior road and abutting properties shall be minimized by the use of changes in topography, existing vegetation, or additional landscaping that meets landscaping requirements of the zoning ordinance or development regulations of Cherokee County.
C.

D.
All lots shall abut an undisturbed area of greenspace of 50 feet in depth, either primary or secondary, except as otherwise permitted herein.
E.
Common greens may be included in the community design. An individual green should be not less than 5,000 square feet. Greens should be surrounded by streets and dwellings on at least two sides. Dwellings should face the green. Common greens may be designed as terminal vistas within a street system.
F.
Provide pedestrian and maintenance access to greenspace land such that no more than ten lots shall be contiguous to each other without a centrally located greenspace access point meeting the following standards:
1.
The minimum width of the greenspace access strip shall equal the minimum width of the abutting lots, and in no case be less than 50 feet.
2.
The minimum width of the greenspace access strip shall extend the full depth of the adjacent lots
G.
At least two corners of all interior road intersections must have a minimum of 900 square foot landscaped common area outside of the right-of-way.
(Ord. No. 2019-O-019, § 1, 12-3-19)
"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.
23.6-1. Standards to determine greenspace.
A.
The minimum greenspace shall comprise at least 40 percent of the adjusted tract area, in addition to the total area of all natural constrained lands from section 23.4-2(1) a through e.
B.
To the extent practicable, greenspace shall be preserved in larger, contiguous, undisturbed and connected tracts so as to provide uninterrupted habitat. The greenspace should adjoin any neighboring areas of Greenspace, other protected areas, and non-protected natural areas that would be candidates for inclusion as part of a future area of protected greenspace.
23.6-2. Primary conservation areas.
A.
Primary Conservation areas are lands that serve important ecological purposes and possess beneficial environmental qualities contributing to the health of the local community. All land identified as primary conservation areas shall be undisturbed, except as provided herein. Primary conservation areas include:
1.
The 100-year floodplain.
2.
Riparian zones of at least 50 feet width on either side along all perennial and intermittent streams.
3.
Riparian zones of at least 150 feet width on either side of the Etowah River Corridor or the Little River Corridor
4.
Slopes steeper than 35 percent that have an extent of at least 5,000 square feet of contiguous area

Jurisdictional wetlands as defined by the Army Corps of Engineers pursuant to the Clean Water Act.
6.
Populations of endangered or threatened species, or habitat for such species.
7.
Bodies of water with surface area of 5,000 square feet or greater.
B.
Value of primary conservation areas. Primary conservation areas form the core of the greenspace to be protected. Because primary conservation areas are sensitive environmental areas, Cherokee County requires such areas be permanently protected through the thoughtful design and protection instruments outlined herein. The total area of land identified as primary conservation areas shall be conserved and protected to the maximum amount and extent physically possible.
23.6-3 Secondary conservation areas.
A.
The following are considered secondary conservation areas and should be protected to the maximum extent feasible and shall be undisturbed, except as provided herein:
1.

23.7-5 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.
(Ord. No. 2019-O-019, § 1, 12-3-19)
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.
A.
Step 1: Delineation of greenspace lands.
1.
The minimum percentage and acreage of required greenspace lands shall be calculated by the applicant and delineated as part of the concept/preliminary plan in accordance with this ordinance. Greenspace lands shall include all primary conservation areas and those parts of the secondary conservation areas, as defined herein, to meet the terms of this ordinance.
2.
Proposed greenspace lands shall be designated using the existing resource/site analysis map as a base map.
3.
In delineating secondary conservation areas, the applicant shall consult with planning staff on the prioritization of natural and cultural resources on the tract in terms of their highest to least suitability for inclusion in the proposed greenspace.
4.
Using the priorities and practical considerations given to the tract's configuration, its context in relation to resource areas on adjoining and neighboring properties, and the applicants subdivision objectives, secondary conservation areas shall be delineated to meet at least the minimum area percentage requirements for greenspace lands and in a manner clearly indicating their boundaries as well as the types of resources included within them.
B.
Step 2: Location of house sites.
1.
Potential house sites shall be tentatively located using the proposed greenspace lands as a base map as well as other relevant data on the existing resources map such as topography and soils. House sites should be located not closer than 100 feet from primary conservation areas and 50 feet from secondary conservation areas, taking into consideration the potential negative impacts of residential development on such areas as well as the potential positive benefits of such locations to provide attractive views and visual settings for residences.
2.
The area of a potential house site should be representative of the largest footprint of a house which may be proposed within the conservation design community. The proposed footprint should include areas such as the primary residence, and any driveways, patios, decks, porch, pool, if such are planned to be constructed concurrent with proposed primary residence
C.
Step 3: Alignment of streets and trails.
1.
Upon designating the house sites, a street plan shall be designed to provide vehicular access to each house, complying with the standards for road design in the Cherokee County Development Regulations and bearing a logical relationship to topographic conditions.
D.
Step 4: Drawing in the lot lines.
1.
Upon completion of the preceding three steps, lot lines are drawn as required to delineate the boundaries of individual residential lots. Lot lines are drawn as the last step.
(Ord. No. 2019-O-019, § 1, 12-3-19)
Roads for the conservation design community shall follow road construction guidelines consistent with those set forth in the Cherokee County Development Regulations, chapter 1, Development Ordinance, section 4.05. The design of streets, within the conservation design community, where possible and with the approval of the county engineer, should:
1.
Minimize the number of cul-de-sac streets by providing more than one entrance to the development and interconnect streets as much as possible.
2.
For cul-de-sac streets, use grass and vegetation for the inner circle of turn-arounds, rather than paving the entire area. Declare the HOA responsible for the maintenance of the grassy area in the neighborhood bylaws
3.
Omit curbs wherever appropriate.
4.
As an alternative to curbs and gutters, allow runoff from roofs and pavements to pass immediately through grass swales or infiltration basins. Use plant material that will absorb rainwater and act as a natural filter for oil and pollution.
5.
Provide marked, paved paths for non-vehicular traffic within the development and connecting to neighboring residential and commercial areas.
(Ord. No. 2019-O-019, § 1, 12-3-19)
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.
A.
Trails. Where trails are planned to be provided, such trails may be constructed within the buffer area. The path through the buffer area containing such trail may be no wider than eight feet. All clearing associated with the construction of such path shall be contained within the eight feet. If such trails are planned as a part of the development, the trails must be located within the first 25 percent of the buffer furthest from the exterior boundary line for the subdivision but in no event shall be within 30 feet of said exterior boundary line, unless abutting another greenspace.
23.10-1 Size of buffer. The size of the exterior buffer shall be a minimum of 50 feet 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 feet.
23.10-2 Buffer counts toward greenspace requirement. The area of land designated to the 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.

- CONSERVATION DESIGN COMMUNITY9
Editor's note—Ord. No. 2019-O-019, § 1, adopted Dec. 3, 2019, amended Art. 23, in effect deleting Art. 23 and enacting a new Art. 23 to read as set out herein. Former Art. 23 pertained to similar subject matter and derived from Ord. No. 2005-Z-001, adopted Apr. 19, 2005; Ord. No. 2009-Z-001, adopted Sept. 15, 2009; and Ord. No. 2014-O-001, Exh. A, adopted Aug. 19, 2014.
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:
1.
Preserve significant areas of land for ecological, recreational, and agricultural purposes in perpetuity;
2.
Encourage more efficient development of land consistent with public health, safety, and general welfare;
3.
Afford greater flexibility of design and placement of buildings and structures;
4.
Preserve and protect exceptional terrain, natural beauty, and sites of historic interest from inconsequential placement of homes, roadways, utilities, and appurtenances;
5.
Preserve the Etowah River and its streams and tributaries as natural resources;
6.
Prevent flooding, erosion, and water pollution, and protect the quality and quantity of drinking water;
7.
Preserve wetlands, aquifers, topographical, or soil features, marine and wildlife habitat; and other features having conservation values, including views, vistas, and indigenous vegetation; and
8.
Promote a less sprawling form of development (within the site of development).
(Ord. No. 2019-O-019, § 1, 12-3-19)
A.
Applicability of regulations. In order to achieve the purposes described in section 23.1, the conservation design community is available as a use in the single-family residential and agricultural (AG, R-80, R-60, R-40, R-30, R-20) zoning districts. Any property rezoned after December 3, 2019 upon which the property owner proposes a conservation design community, said plan must be approved by the board of commissioners. However, if the zoning of the property was established prior to December 3, 2019 a property owner may prepare a conservation design community plan according to the provisions of this article to be approved administratively. Applicants utilizing the conservation design community regulations shall comply with all other provisions of the Cherokee County Zoning Ordinance and all other applicable laws, except those that are incompatible with the provisions contained herein.
1.
Conservation design community plan approval in AG and R-80: The board of commissioners shall approve a site plan for a conservation design community on property zoned AG or R-80 in accordance with the following:
i.
Prior to submitting a complete application to the county for review, the applicant shall host a community information and input meeting and provide a meeting summary and sign-in sheet, as outlined in article 18.3-5 of the Cherokee County Zoning Ordinance, and a list of participants to such meeting shall be submitted to the county.
ii.
Once a community input and information meeting has been conducted, a complete application shall be submitted to the county. A complete application shall follow all requirements outlined in this article.
iii.
The applicant shall post notice on the subject property announcing an application for a conservation design community has been received by the county for consideration. the sign shall be posted no less than 30 calendar days prior to the site plan review by the board of commissioners.
iv.
A 30 day "public comment" period shall be required after receipt by the county of the complete application and notice has been posted on the property. All parties wishing to comment shall submit their comments to the county.
v.
Upon the expiration of the public comment period, the county shall place the application for a conservation design community on the next available agenda of the board of commissioners. At their meeting, the board of commissioners shall consider approval of the site plan. The board of commissioners shall approve a site plan upon finding the proposed subdivision meets the purpose of a conservation design community per section 23.1 of the zoning ordinance.
B.
Ownership of development site. The tract of land to be designed as a conservation design community may be held in single ownership or in multiple ownership. However, when a tract is held in multiple ownership, it shall be planned as a single development, and developed according to a single plan.
1.
Phased development: Unless approved under a concept/preliminary plan as outlined herein, each phase of a conservation design community must meet the density criteria established herein and may not exceed the density for the zoning district.
2.
Proof of ownership: The developer of a conservation design community must provide documentation of ownership of all land to be developed as a conservation design community prior to approval of a land disturbance permit for the development. Only lands that may be considered for development as a conservation design community are those lands owned by the applicant for the land disturbance permit.
C.
Site suitability. As evidenced by the existing resources/site analysis map, the conservation design community concept/preliminary plan, and the final plat, the tract incorporating the conservation design community shall be suitable for supporting development in terms of environmental conditions, size, and configuration as determined herein.
D.
Sensitive area disturbance. The proposed design shall minimize disturbance of environmentally sensitive areas, as shown on the existing resources/site analysis map. Lands within the 100-year floodplain, designated as wetlands, having slopes in excess of 35 percent, and riparian buffers adjacent to streams constitute such environmentally sensitive areas. Demonstration by the applicant that these features shall be protected by the proposed application shall be prerequisite to consideration and approval of the conservation design community concept/preliminary plan and subsequent final plat.
E.
Minor subdivisions prohibited. Minor subdivisions, whereby an original tract of land may be divided into not more than five individual tracts, are not eligible to be developed per the conservation regulations contained herein. Only major subdivisions, those subdivisions of land resulting in the creation of six or more lots, are permissible to be developed according to the Conservation Design Community regulations outlined in this article.
F.
Effect of concept/preliminary plan. Approval of the concept/preliminary plan shall bind all land within the plan to the requirements and conditions of the conservation design community regulations. Should the developer or land owner subsequently sell or otherwise transfer their interest in the property, all heirs and assigns shall be bound to the approved concept/preliminary plan, unless amended by and/or approved by the board of commissioners.
G.
Size of a conservation design community. A tract of land to be developed as a conservation design community shall contain not less than 30 contiguous acres and be of a configuration that is conducive to a conservation design community. The simultaneous planning of larger and adjacent parcels is encouraged.
Notwithstanding the provisions noted above, a conservation design community may have land that is less than 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:
1.
The property is adjacent to or across a street from property that has been developed as a conservation design community, and a conservation design community will contribute to the maintenance of the character, amenities, and conservation values of the neighboring conservation design community; or
2.
The property immediately adjoins and proposes to extend the greenspace from an adjoining conservation design community through the subject property and create a larger area of greenspace; or
3.
The property immediately adjoins a publicly designated "greenway" and proposes to extend the "greenway" through the subject property; or
4.
At the discretion of the board of commissioners, the development of a property as a conservation design community on less than 30 contiguous acres would be in the public interest.
(Ord. No. 2019-O-019, § 1, 12-3-19; Res. No. 2023-R-049, Exh. A, 6-20-23)

(Ord. No. 2019-O-019, § 1, 12-3-19)
23.4-1. 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.
1.
Method 1 - Yield Plan. Prepare a plan that demonstrates the maximum number of lots for a conventional subdivision on the site. The conventional plan does not have to meet formal requirements for a site design plan, but must address the site features and all applicable regulations, including storm water and development regulations. The conventional subdivision plan must be reviewed by county staff, prior to submitting a preliminary plan for a conservation design community to assess whether such plan meets the requirements for a conventional design.
i.
Yield plans must be prepared in accordance with subdivision regulations, and show proposed lots, streets, rights-of-way, and other pertinent features. The plan must reflect federal, state or local restrictions on building within and/or disturbance of wetlands, floodplains, steep slopes, existing easements or encumbrances, and if using septic, the suitability of soils for sewage disposal.
ii.
Yield plans shall reflect the dimensional standards for lots based on zoning district requirements, ie. Lot area, lot width, building setbacks, etc.
iii.
Where site is not served by sewer, the density shall be determined by evaluating the number of homes that could be served by individual on-site sewage management systems on conventional lots.
iv.
Yield plan must identify the primary and secondary site resources, and demonstrate that such primary resources can remain undisturbed, by allocating these areas to proposed lots.
v.
No more than 25 percent of the lot area of any individual lot may be within the 100-year floodplain or any body of water.
vi.
Road right-of-way on a yield plan shall use a minimum of a 50 foot width. Lot lines shall begin at edge of 50 foot ROW.
2.
Method 2-Adjusted tract acreage. Determine the area of constrained lands as defined in section 23.4-2, make adjustments in accordance with section 23.4-2.1 and subtract the net constrained land acreage from the gross tract acreage. The resulting adjusted tract acreage is then multiplied by the zoning district DUA (dwelling units per acre). (see Table 23-1)
3.
The greater number of lots calculated by either method (1) or method (2) is the "maximum allowed lots" in the conservation design community.
23.4-2. Calculating adjusted tract acreage.
1.
Determine the area of constrained lands.
Net Constrained Lands = Area of land in items a-e multiplied by 0.50, plus 100 percent of area of land in items f—g below.
a.
Slopes steeper than 35 percent that have an extent of at least 5,000 square feet of contiguous area.
b.
The 100-year floodplain.
c.
Jurisdictional wetlands as defined by the Army Corps of Engineers pursuant to the Clean Water Act.
d.
State waters.
e.
Area of land in stream buffers as required by federal, state or local regulations that are beyond the limits of items b. and c. above.
f.
Area of land designated for construction of permanent roads and associated ROW.
g.
Area of all impervious surfaces associated with amenities, including but not limited to parking areas, tennis courts, swimming pools, clubhouses and other similar amenities.
2.
Adjusted tract 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.
3.
Allowed lots by conservation design community:
The number of lots allowed is determined by multiplying adjusted tract acreage by the maximum of dwelling units per acre for the zoning district.
4.
Lot sizes.
In a conservation design community, up to ten percent of the lot total may be platted less than the average lot size but not less than the minimum lot size in Table 23-1. The lot size for all other lots must be at least the average lot size for the corresponding zoning district in accordance with Table 23-1. The average size of all lots within a conservation design community must meet or exceed the average lot size in Table 23-1 for the corresponding zoning district. There is no maximum lot size.
Table 23-1: Conservation Design Community Density and Lot Size Requirements
23.4-3 Area and yard requirements; locations and structures.
23.4-3.1 Placement. The placement of all principal buildings shall provide for safe, quiet, and harmonious grouping as well as adequate privacy by providing adequate front, side, and rear yards as shown in Table 23-2.
a.
There shall be a minimum building separation requirement of 15 feet between structures on adjacent lots. At no time shall any building be constructed where the setback from a side property line is less than the width of the eaves of the structure or five feet whichever is greater.
Table 23-2: Conservation Design Community Setback Requirements
(Ord. No. 2019-O-019, § 1, 12-3-19)
A.
House lots shall not encroach upon primary conservation areas, and their layout shall respect secondary conservation areas, as described herein.
B.
Views of house lots from exterior road and abutting properties shall be minimized by the use of changes in topography, existing vegetation, or additional landscaping that meets landscaping requirements of the zoning ordinance or development regulations of Cherokee County.
C.

D.
All lots shall abut an undisturbed area of greenspace of 50 feet in depth, either primary or secondary, except as otherwise permitted herein.
E.
Common greens may be included in the community design. An individual green should be not less than 5,000 square feet. Greens should be surrounded by streets and dwellings on at least two sides. Dwellings should face the green. Common greens may be designed as terminal vistas within a street system.
F.
Provide pedestrian and maintenance access to greenspace land such that no more than ten lots shall be contiguous to each other without a centrally located greenspace access point meeting the following standards:
1.
The minimum width of the greenspace access strip shall equal the minimum width of the abutting lots, and in no case be less than 50 feet.
2.
The minimum width of the greenspace access strip shall extend the full depth of the adjacent lots
G.
At least two corners of all interior road intersections must have a minimum of 900 square foot landscaped common area outside of the right-of-way.
(Ord. No. 2019-O-019, § 1, 12-3-19)
"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.
23.6-1. Standards to determine greenspace.
A.
The minimum greenspace shall comprise at least 40 percent of the adjusted tract area, in addition to the total area of all natural constrained lands from section 23.4-2(1) a through e.
B.
To the extent practicable, greenspace shall be preserved in larger, contiguous, undisturbed and connected tracts so as to provide uninterrupted habitat. The greenspace should adjoin any neighboring areas of Greenspace, other protected areas, and non-protected natural areas that would be candidates for inclusion as part of a future area of protected greenspace.
23.6-2. Primary conservation areas.
A.
Primary Conservation areas are lands that serve important ecological purposes and possess beneficial environmental qualities contributing to the health of the local community. All land identified as primary conservation areas shall be undisturbed, except as provided herein. Primary conservation areas include:
1.
The 100-year floodplain.
2.
Riparian zones of at least 50 feet width on either side along all perennial and intermittent streams.
3.
Riparian zones of at least 150 feet width on either side of the Etowah River Corridor or the Little River Corridor
4.
Slopes steeper than 35 percent that have an extent of at least 5,000 square feet of contiguous area

Jurisdictional wetlands as defined by the Army Corps of Engineers pursuant to the Clean Water Act.
6.
Populations of endangered or threatened species, or habitat for such species.
7.
Bodies of water with surface area of 5,000 square feet or greater.
B.
Value of primary conservation areas. Primary conservation areas form the core of the greenspace to be protected. Because primary conservation areas are sensitive environmental areas, Cherokee County requires such areas be permanently protected through the thoughtful design and protection instruments outlined herein. The total area of land identified as primary conservation areas shall be conserved and protected to the maximum amount and extent physically possible.
23.6-3 Secondary conservation areas.
A.
The following are considered secondary conservation areas and should be protected to the maximum extent feasible and shall be undisturbed, except as provided herein:
1.
Important historic sites subject to approval indicating that these structures are compatible with the Cherokee Zoning Regulations.
2.
Existing healthy, native forests of at least one acre contiguous area
3.

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.
(Ord. No. 2019-O-019, § 1, 12-3-19)
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.
A.
Step 1: Delineation of greenspace lands.
1.
The minimum percentage and acreage of required greenspace lands shall be calculated by the applicant and delineated as part of the concept/preliminary plan in accordance with this ordinance. Greenspace lands shall include all primary conservation areas and those parts of the secondary conservation areas, as defined herein, to meet the terms of this ordinance.
2.
Proposed greenspace lands shall be designated using the existing resource/site analysis map as a base map.
3.
In delineating secondary conservation areas, the applicant shall consult with planning staff on the prioritization of natural and cultural resources on the tract in terms of their highest to least suitability for inclusion in the proposed greenspace.
4.
Using the priorities and practical considerations given to the tract's configuration, its context in relation to resource areas on adjoining and neighboring properties, and the applicants subdivision objectives, secondary conservation areas shall be delineated to meet at least the minimum area percentage requirements for greenspace lands and in a manner clearly indicating their boundaries as well as the types of resources included within them.
B.
Step 2: Location of house sites.
1.
Potential house sites shall be tentatively located using the proposed greenspace lands as a base map as well as other relevant data on the existing resources map such as topography and soils. House sites should be located not closer than 100 feet from primary conservation areas and 50 feet from secondary conservation areas, taking into consideration the potential negative impacts of residential development on such areas as well as the potential positive benefits of such locations to provide attractive views and visual settings for residences.
2.
The area of a potential house site should be representative of the largest footprint of a house which may be proposed within the conservation design community. The proposed footprint should include areas such as the primary residence, and any driveways, patios, decks, porch, pool, if such are planned to be constructed concurrent with proposed primary residence
C.
Step 3: Alignment of streets and trails.
1.
Upon designating the house sites, a street plan shall be designed to provide vehicular access to each house, complying with the standards for road design in the Cherokee County Development Regulations and bearing a logical relationship to topographic conditions.
D.
Step 4: Drawing in the lot lines.
1.
Upon completion of the preceding three steps, lot lines are drawn as required to delineate the boundaries of individual residential lots. Lot lines are drawn as the last step.
(Ord. No. 2019-O-019, § 1, 12-3-19)
Roads for the conservation design community shall follow road construction guidelines consistent with those set forth in the Cherokee County Development Regulations, chapter 1, Development Ordinance, section 4.05. The design of streets, within the conservation design community, where possible and with the approval of the county engineer, should:
1.
Minimize the number of cul-de-sac streets by providing more than one entrance to the development and interconnect streets as much as possible.
2.
For cul-de-sac streets, use grass and vegetation for the inner circle of turn-arounds, rather than paving the entire area. Declare the HOA responsible for the maintenance of the grassy area in the neighborhood bylaws
3.
Omit curbs wherever appropriate.
4.
As an alternative to curbs and gutters, allow runoff from roofs and pavements to pass immediately through grass swales or infiltration basins. Use plant material that will absorb rainwater and act as a natural filter for oil and pollution.
5.
Provide marked, paved paths for non-vehicular traffic within the development and connecting to neighboring residential and commercial areas.
(Ord. No. 2019-O-019, § 1, 12-3-19)
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.
A.
Trails. Where trails are planned to be provided, such trails may be constructed within the buffer area. The path through the buffer area containing such trail may be no wider than eight feet. All clearing associated with the construction of such path shall be contained within the eight feet. If such trails are planned as a part of the development, the trails must be located within the first 25 percent of the buffer furthest from the exterior boundary line for the subdivision but in no event shall be within 30 feet of said exterior boundary line, unless abutting another greenspace.
23.10-1 Size of buffer. The size of the exterior buffer shall be a minimum of 50 feet 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 feet.
23.10-2 Buffer counts toward greenspace requirement. The area of land designated to the 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.
