CHAPTER 7 | FORM-BASED ZONING DISTRICT

Sec. 7.1.1 Authority

The South Carolina Local Government Comprehensive Planning Enabling Act of 1994, as amended (Planning Act) authorizes local governments to utilize zoning and planning techniques (not limited to those found in the Planning Act) for implementation of the goals specified in S.C. Code Ann. Sec. 6-29-720 (2007). Charleston County Council hereby establishes a zoning and planning technique called a Form-Based Zoning District (FBZD). A FBZD is a zoning district which allows development of lands containing mixed residential, civic, institutional, commercial, and/or industrial uses in development patterns similar to those present in Charleston County and the Lowcountry. Use of the FBZD requires the applicant to submit form-based zoning regulations in the form of a Form District Master Plan that is structured on a Rural to Urban Transect.

Effective on: 1/1/1901, as amended

Sec. 7.1.2 Applicability

Land may be zoned FBZD only if the definition and requirements of Article 3.17, Developments of County Significance, are met. Developments of County Significance (DCS) allow for the submittal of FBZD applications when such applications are accompanied by applications for Comprehensive Plan Amendments (pursuant to Article 3.2 of this Ordinance) and Development Agreements (pursuant to Article 3.16 of this Ordinance).

With its unique transect patterns, the FBZD facilitates the development of compact communities and at the same time allows the preservation of agricultural patterns and activities, and the maintenance of the character of the Rural Area.

Effective on: 1/1/1901, as amended

Sec. 7.1.3 Purpose and Intent

The Charleston County Comprehensive Plan contains six overarching themes that serve as the primary guidance for the implementation of recommended strategies. One such theme is the creation of Sustainable Communities through a balancing of social, economic, and environmental considerations such as provision of affordable housing, mixing of uses, and preservation of natural resources. The Comprehensive Plan also emphasizes the form and quality of development in the County and includes guidelines for the character of development in both the Rural Area and the Urban/Suburban Area.

The purpose and intent of this Chapter is to implement the Comprehensive Plan’s emphasis on Sustainable Development and development form and quality through the FBZD. As described in Sec. 3.1.7(D) of the Comprehensive Plan (2008, as amended), the FBZD is a zoning district category and a planning tool that guides form and character to create development patterns that coordinate the location of a variety of land uses with a connected transportation network in a manner that accommodates pedestrian mobility and controls sprawl.

The FBZD enables the development of communities in rural areas in a manner that emphasizes their form and development pattern rather than emphasizing a discrete set of land uses. It facilitates planned, sustainable growth patterns, and enables the coordination of transportation, housing, employment, and services to provide communities and neighborhoods where people can live and work.

The Comprehensive Plan recognizes that the projected build-out of any parcel zoned FBZD may far exceed the time frame of the current Comprehensive Plan and that any long-term community planning process may require the consideration of land use planning strategies not currently envisioned. The FBZD enables predictability in the planning process by directing the intended form and character of a place, while allowing it to naturally grow and evolve over time in response to market conditions.

More specifically, the FBZD addresses a variety of planning and development scales, including Sectors, Settlements, Communities, Blocks, Lots and Buildings, as described below:

A.
Within Developments of County Significance in the Rural Area, the FBZD:
1. 1.
  Encourages the Development of Settlements and Communities which provide a range of complementary land uses, including but not limited to residential, non-residential, and mixed uses.
2. 2.
  Promotes flexibility in site planning and structure location that facilitates the provision and use of efficient circulation and utility systems, and preservation of natural and scenic features, resulting in diversity of scale, style, and details that foster a strong sense of community.
3. 3.
  Encourages a framework of transit, pedestrian, and bicycle systems that provide alternatives to the automobile.
4. 4.
  Promotes growth patterns that accommodate various types of protected open space, rural development, and planned growth, and that provide a tool to proactively manage long-term, planned growth while encouraging long-term land use planning by facilitating predictability and flexibility in the approvals process.
5. 5.
  Promotes connectivity of preserved/protected land and Civic Space.
B.
Within Town, Village, Corner, and Crossroad Settlements, the FBZD:
1. 1.
  Promotes, preserves, and enhances community design that reflects the distinct character of Charleston County and supports a range of vibrant human habitats.
2. 2.
  Promotes compact development patterns that consolidate open space, preserve natural and scenic features, and provide access to trails and natural areas.
3. 3.
  Promotes development patterns that support safe, walkable, pedestrianoriented, mixed-use places.
4. 4.
  Promotes development patterns that support safe, effective, and multimodal transportation options, including but not limited to auto, pedestrian, and bicycle, minimizing vehicle traffic by providing a mix of land uses, walkability, and compact community form.
5. 5.
  Promotes development patterns that facilitate the provision and use of efficient circulation and utility systems.
6. 6.
  Promotes the health benefits of pedestrian-oriented places, including safe routes for walking, bicycling and other exercise.
C.
Within New Communities, the FBZD:
1. 1.
  Encourages walkable neighborhoods through networks of well-designed streets that are safe and secure for pedestrians and bicycles.
2. 2.
  Encourages appropriately scaled development that places services within a safe, comfortable walking distance of homes.
3. 3.
  Encourages and incubates local business activity and economic sustainability through community design.
4. 4.
  Promotes neighborhoods with quality housing that encourage a diversity of housing choices and accommodate diverse ages and incomes.
5. 5.
  Promotes neighborhood form that facilitates the provision and use of efficient circulation and utility systems.
6. 6.
  Integrates civic, institutional, and other services into the fabric of communities. In areas designated for the location of schools, schools should be encouraged to be of size and location to enable children to walk or bicycle to them.
D.
Within Blocks and Buildings:
1. 1.
  Encourages that each building plays a role in creating a better whole, not just a good building.
2. 2.
  Encourages buildings and environments that can adapt to changing economics and demographics.
3. 3.
  Encourages that architecture and landscape grow from local climate, history, and building practice.
4. 4.
  Promote the placement of civic buildings in important locations and promote a form that reflects their civic stature.
5. 5.
  Promote building form that facilitates the provision and use of efficient utility systems.

The FBZD enables the applicant to propose a Form-Based Code unique to the development. Form-Based Codes are an alternative approach to zoning that reinforces walkable, sustainable, mixed-use environments and development, and builds upon the character of a place. The Form-Based Codes Institute defines Form-Based Codes as follows:

“Form-Based Codes foster predictable built results and a high-quality public realm by using physical form (rather than the separation of uses) as the organizing principle for the code. These codes are adopted into city or county law as regulations, not mere guidelines. Form-Based Codes are an alternative to conventional zoning.”

The FBZD enables property owners to designate a set of zones utilizing the Rural-to-Urban Transect. The Transect is a tool that considers development character, scale, and intensity, rather than a Euclidean zoning framework in which use, rather than form, is the primary focus. The Form-Based Codes Institute describes the Rural to Urban Transect as follows:

“The Rural-to-Urban Transect is a means for considering and organizing the human habitat in a continuum of intensity that ranges from the most rural condition to the most urban. It provides a standardized method for differentiating between the intentions for urban form in various areas using gradual transitions rather than harsh distinctions. The zones are primarily classified by the physical intensity of the built form, the relationship between nature and the built environment, and the complexity of uses within the zone.”

The model transect for American cities is divided into six transect zones or T-Zones: Natural (T1), Rural (T2), Sub-urban (T3), General Urban (T4), Urban Center (T5), and Urban Core (T6), together with a Special District (SD) designation for areas with specialized purpose (e.g., heavy industrial, transportation, entertainment, or university districts, among other possibilities).

Because the Charleston County FBZD only applies to rural areas of the County, this Ordinance allows the use of T-Zones T1 through T5 as well as Special Districts.

FIGURE 7.1.A: Rural-to-Urban Transect.
The transect is a geological cross-section which reveals a sequence of environments. This range of human environments, from rural to urban, provides a rational basis for organizing the components of the built environment including buildings, lots, land use, civic space, streets, and other elements.

FIGURE 7.3.C: Settlement Type Diagram Examples
The following illustrative images describe the Charleston County Settlement Types that display a Community Unit or a group of Community Units located in general proximity with each other.
Crossroads. The smallest rural settlement type located at the intersection of two local roads. A crossroad is comprised of a compact cluster of homes about an intersection that is surrounded by countryside or agricultural lands. A corner store or civic use may mark the corner.	Corner. A rural settlement type that is larger than a crossroads and located at a significant crossroads or open space. A Corner is comprised of a compact cluster of homes organized in a walkable community with limited commercial services or civic uses, surrounded by countryside or agriculture.
Village. An urban settlement type organized into multiple walkable neighborhoods of compact clusters of various dwelling types, including mixed-use buildings, surrounded by countryside. A range of commercial services and civic activities provide for the daily needs of its residents. The population of a village is larger than in a corner but smaller than a town.	Towns. The most urban settlement type is an aggregation of walkable neighborhoods that mix residential, commercial, and civic uses. Located along or at the intersection of a major thoroughfare, the center provides for the daily need of its residents as well as those of visitors from around the region and thus accommodates the parking needs of local and transient users.

1. 2.
  Sectors Defined. Sectors are geographical areas that are comprised of 75% Acreage and growth areas. Growth areas are intended for the development of new settlements and communities in the form of Settlement Types and Community Types, which in turn are comprised of Transect Zones and Special Districts.

    (2).
    The Reserved Open Sector (O-2) shall consist of rural development patterns and activities and may include a mix of Separate Rural Development and open space.
    (3).
    The Restricted Growth Sector (G-1) shall be assigned to areas that have value as open space but are appropriate for development of restricted or limited intensity that is clustered.
    (4).
    The Controlled Growth Sector (G-2) shall be assigned to areas that can support a variety of mixed-use development patterns by virtue of proximity to existing infrastructure, including clustered land development and traditional neighborhood developments.
    (5).
    The Intended Growth Sector (G-3) shall be assigned to areas that can support substantial mixed-use development patterns by virtue of proximity to existing infrastructure, including traditional neighborhood developments and regional center developments.
2. 3.
  Special Districts. Special Districts may only be proposed when Sectors are utilized and the Planning Director determines the following:
  1. a.
    That proposed Special Districts comply with the requirements of Sec. 7.4.7; and
  2. b.
    That development patterns in their intrinsic size, function, or configuration cannot conform to the requirements of Settlements or their corresponding Community Types.

Range of uses include corner stores, single family detached residences, and farms.
4. Rural Development. Rural areas may be composed of Separate Rural Development. Separate Rural Developments shall maintain rural densities and activities in a sparsely developed pattern.

Clustered Growth/Urban Places.

Villages. Villages are compact clusters of dwellings of mixed type, including mixed-use buildings, surrounded by undeveloped land, countryside or agricultural lands, organized into walkable neighborhoods, with a range of commercial services and civic activities that provide for the daily needs of its residents. The population of a village is larger than in a corner but smaller than a town.
Towns. Towns are larger than a village, an aggregation of walkable neighborhoods that mix residential, commercial, and civic uses, typically located along or at the intersection of a major thoroughfare. The town’s center provides for the daily need of its residents as well as those of visitors from around the region and thus accommodates the parking needs of local and transient users.
Towns provide adequate densities in support of frequent transit.

Settlements may be organized by Sector as described in Table 7.3.3.

	SECTION Lot > \| < R.O.W. Frontage \| Frontage	PLAN Lot > \| < R.O.W. Private > \| < Public Frontage Frontage
a. Common Yard: a planted Frontage wherein the Facade is set back substantially from the Frontage Line. The front yard created remains unfenced and is visually continuous with adjacent yards, supporting a common landscape. The deep Setback provides a buffer from the higher speed Thoroughfares.
b. Porch & Fence: a planted Frontage wherein the Facade is set back from the Frontage Line with an attached porch permitted to Encroach. A fence at the Frontage Line maintains street spatial definition. Porches shall be no less than 8 feet deep.
c. Terrace or Lightwell: a Frontage wherein the Facade is set back from the Frontage line by an elevated terrace or a sunken Lightwell. This type buffers Residential use from urban Sidewalks and removes the private yard from public Encroachment. Terraces are suitable for conversion to outdoor cafes. Syn: Dooryard.
d. Forecourt: a Frontage wherein a portion of the Facade is close to the Frontage Line and the central portion is set back. The Forecourt created is suitable for vehicular drop-offs. This type should be allocated in conjunction with other Frontage types. Large trees within the Forecourts may overhang the Sidewalks.
e. Stoop: a Frontage wherein the Facade is aligned close to the Frontage Line with the first Story elevated from the Sidewalk sufficiently to secure privacy for the windows. The entrance is usually an exterior stair and landing. This type is recommended for ground-floor Residential use.
f. Shopfront: a Frontage wherein the Facade is aligned close to the Frontage Line with the building entrance at Sidewalk grade. This type is conventional for Retail use. It has a substantial glazing on the Sidewalk level and an awning that may overlap the Sidewalk to within 2 feet of the Curb. Syn: Retail Frontage.
g. Gallery: a Frontage wherein the Facade is aligned close to the Frontage line with an attached cantilevered shed or a lightweight colonnade overlapping the Sidewalk. This type is conventional for Retail use. The Gallery shall be no less than 10 feet wide and should overlap the Sidewalk to within 2 feet of the Curb.
h. Arcade: a colonnade supporting habitable space that overlaps the Sidewalk, while the Facade at Sidewalk level remains at or behind the Frontage Line. This type is conventional for Retail use. The Arcade shall be no less than 12 feet wide and should overlap the Sidewalk to within 2 feet of the Curb.

It has a substantial glazing on the Sidewalk level and an awning that may overlap the Sidewalk to within 2 feet of the Curb. Syn: Retail Frontage.
g. Gallery: a Frontage wherein the Facade is aligned close to the Frontage line with an attached cantilevered shed or a lightweight colonnade overlapping the Sidewalk. This type is conventional for Retail use. The Gallery shall be no less than 10 feet wide and should overlap the Sidewalk to within 2 feet of the Curb.
h. Arcade: a colonnade supporting habitable space that overlaps the Sidewalk, while the Facade at Sidewalk level remains at or behind the Frontage Line. This type is conventional for Retail use. The Arcade shall be no less than 12 feet wide and should overlap the Sidewalk to within 2 feet of the Curb.

TABLE 7.4.5-5: Building Disposition
This table approximates the location of the structure relative to the boundaries of each individual Lot, establishing suitable basic building types for each Transect Zone. (Table not subject to change by applicant)
a. Edgeyard: A building that occupies the center of its Lot with Setbacks on all sides. This is the least urban of types as the front yard sets it back from the Frontage, while the side yards weaken the spatial definition of the public Thoroughfare space. The front yard is intended to be visually continuous with the yards of adjacent buildings. The rear yard can be secured for privacy by fences and a well-placed Backbuilding and/or Outbuilding.
b. Sideyard: A building that occupies one side of the Lot with the Setback to the other side. A shallow Frontage Setback defines a more urban condition. If the adjacent building is similar with a blank side wall, the yard can be quite private. This type permits systematic climatic orientation in response to the sun or the breeze. If a Sideyard House abuts a neighboring Sideyard House, the type is known as a twin or double House. Energy costs, and sometimes noise, are reduced by sharing a party wall in this Disposition.
c. Rearyard: A building that occupies the full Frontage, leaving the rear of the Lot as the sole yard. This is a very urban type as the continuous Facade steadily defines the public Thoroughfare. The rear Elevations may be articulated for functional purposes. In its Residential form, this type is the Rowhouse. For its Commercial form, the rear yard can accommodate substantial parking.
d. Courtyard: A building that occupies the boundaries of its Lot while internally defining one or more private patios. This is the most urban of types, as it is able to shield the private realm from all sides while strongly defining the public Thoroughfare. Because of its ability to accommodate incompatible activities, masking them from all sides, it is recommended for workshops, Lodging and schools. The high security provided by the continuous enclosure is useful for crime-prone areas.
e. Specialized: A building that is not subject to categorization. Buildings dedicated to manufacturing and transportation are often distorted by the trajectories of machinery. Civic buildings, which may express the aspirations of institutions, may be included.

Community Plan Submittals - Standards. Subsequent Community Plan applications shall designate Transect Zones on a Regulating Plan, in accordance with the procedures for Community Plans in Sec. 7.2.3.B, Community Plans, and the following standards:
1. 1.
  Transition between Transect Zones. When applying Transect Zones, transitions between the T5, T4, and T3 Transect Zones are encouraged to occur within the block or across alleys but may occur across a street.
2. 2.
  Transect Organization. Transects shall be organized in a manner that responds appropriately to a site’s context. More intense Transect Zones shall be organized around neighborhood centers and neighborhood main streets in visible and accessible locations suitable for greater intensities, typically at or near the center of a Pedestrian Shed. Less intense Transect Zones shall generally be organized farther from the center and serve as a transition to natural and open space, and 75% Acreage.
3. 3.
  Transect Allocation. Community Plans for Community Units shall assign and map Transect Zones to each Pedestrian Shed according to the percentages allocated in Table 7.3.B, Sector/Settlement/Community Allocation.

Sec. 7.4.6 Density Calculations

FBZD Application - Standards. At the time of initial FBZD Application, the applicant shall establish a minimum and maximum anticipated density for each proposed Settlement.

Density shall be expressed in terms of Density Units as described in Table 7.4.6, Density Equivalency Calculations.

Community Plan Submittals - Standards.

Community Plans shall designate Transect Zones that establish maximum densities in accordance with Sec. 7.4.5, Transect Zones.
All areas of a Community Plan site (outside of the P-1 Preserved Sector, if applicable) shall be cumulatively considered the Community Unit Net Site Area. The Community Unit Net Site Area shall be allocated to the various
Transect Zones according to the standards established in the applicable Form District Master Plan in accordance with Table 7.3.B, Sector/Settlement/Community Allocation.
1. OCRM Critical Line Areas shall be excluded from the Net Site Area.
The Density for each Transect Zone of a Community Unit shall be expressed in terms of Density Units per acre of Transect Zone Net Site Area. The Transect Zone Net Site Area shall include Thoroughfare rightof-ways but exclude OCRM Critical Line Areas and Civic Space from this calculation.
Density within any Special District shall be provided on Table 7.4.Y, Special District Development Standards. Density calculations shall utilize the functions in Table 7.4.6, Density Calculations, in calculating Special District density.
There shall be no maximum density per Transect Zone applicable to Transect Zone T-1 as that Transect Zone does not contemplate any Uses or Functions creating density.
Lot, Block, and Building Plans shall establish a fixed number of units and related nonresidential program, where applicable.
The total aggregate density of Community Units making up a Settlement shall remain within the minimum and maximum anticipated density ranges established at time of initial FBZD Application.

Table 7.4.6, Density Equivalency Calculations, summarizes the number of density units utilized when making density calculations:

Sec. 7.5.1 Function and Use

Purpose and Intent. This Chapter provides for a variety of mixed-use environments of varying intensity and type within Community Units organized by Transect Zone.

FBZD Application - Standards. Table 7.5.1-1, Specific Function and Use, establishes principal use categories and allowable land use types for Lots and Structures by Transect Zone. At time of initial FBZD application the applicant shall establish uses allowed by right and Uses Subject to Conditions for each Transect Zone and any Special District(s), in accordance with the Purpose and Intent of each Zone, as stated in Table 7.4.R, Transect Zone Descriptions.

One or more Principal Functions may be located on any Lot or in any Building.
Uses Allowed by Right shall be subject to compliance with all other regulations of this Chapter and those in the approved Form District Master Plan.
1. Such regulations may include Conditions specific to a use as may be included by the applicant in the Form District Master Plan.
2. Use conditions set forth in ZLDR Chapter 6, Use Regulations, shall not apply to any use except when expressly adopted in the Form District Master Plan.
Uses Subject to Conditions shall be reviewed according to the procedures in Sec. 7.2.5.B, Uses Subject to Conditions.
New or Unlisted Uses and Use Interpretation. In accordance with Sec. 6.3.5, New or Unlisted Uses and Use Interpretation, the Planning Director shall be authorized to make use determinations whenever there is a question regarding the category of use based on the definitions contained in CHAPTER 12 of the ZLDR. New/unlisted uses may require FBZD amendments if they are not included in the Form District Master Plan or the definitions of Chapter 12, as determined by the Planning Director.
1. Nothing contained herein shall be construed as restricting, limiting or prohibiting a mix of Principal Functions on a Lot or within a Structure. In no event shall a Principal Function be deemed to be an Accessory Use.

Accessory Uses.

Any accessory use or accessory structure that is incidental and customarily subordinate to principal uses shall be treated as a permitted use so long as such uses are located on the same site at the principal use or on a contiguous lot under the same ownership, and so long as they comply with the following standards:
1. Be customarily accessory and clearly incidental and subordinate to the Principal Function or Building;
2. Be subordinate in area, extent, and purpose to the Principal Function or Building;
3. Be owned or operated by the same person as the Principal Function or Building;
4. Together with the Principal Function or Building, not violate the standards of this Chapter or those in the approved Form District Master Plan;
5. Not be constructed or established prior to the time the Principal Function or Structure is constructed or established; and
6. Not constitute a combination use, which is the combination of two principal uses (combination uses will not meet the above standards in terms of being subordinate or providing service to the principal use).
FBZD Application - Standards. At time of initial FBZD application the applicant shall establish the Accessory Uses allowed by right for each Transect Zone.
1. Table 7.5.B establishes a range of typical accessory uses, structures, and activities calibrated to the Transect Zones. The applicant may identify additional accessory uses not listed here. If the accessory use or structure is not allowed in a zone, the column is left blank.
2. The restrictions enumerated for Accessory Uses and Structures in ZLDR CHAPTER 6, Use Regulations, shall not apply to any Accessory Use of Structures except when expressly adopted in the Form District Master Plan.

Sec. 7.1.3 Purpose and Intent

More specifically, the FBZD addresses a variety of planning and development scales, including Sectors, Settlements, Communities, Blocks, Lots and Buildings, as described below:

A.
Within Developments of County Significance in the Rural Area, the FBZD:
1. 1.
  Encourages the Development of Settlements and Communities which provide a range of complementary land uses, including but not limited to residential, non-residential, and mixed uses.
2. 2.
  Promotes flexibility in site planning and structure location that facilitates the provision and use of efficient circulation and utility systems, and preservation of natural and scenic features, resulting in diversity of scale, style, and details that foster a strong sense of community.
3. 3.
  Encourages a framework of transit, pedestrian, and bicycle systems that provide alternatives to the automobile.
4. 4.
  Promotes growth patterns that accommodate various types of protected open space, rural development, and planned growth, and that provide a tool to proactively manage long-term, planned growth while encouraging long-term land use planning by facilitating predictability and flexibility in the approvals process.
5. 5.
  Promotes connectivity of preserved/protected land and Civic Space.
B.
Within Town, Village, Corner, and Crossroad Settlements, the FBZD:
1. 1.
  Promotes, preserves, and enhances community design that reflects the distinct character of Charleston County and supports a range of vibrant human habitats.
2. 2.
  Promotes compact development patterns that consolidate open space, preserve natural and scenic features, and provide access to trails and natural areas.
3. 3.
  Promotes development patterns that support safe, walkable, pedestrianoriented, mixed-use places.
4. 4.
  Promotes development patterns that support safe, effective, and multimodal transportation options, including but not limited to auto, pedestrian, and bicycle, minimizing vehicle traffic by providing a mix of land uses, walkability, and compact community form.
5. 5.
  Promotes development patterns that facilitate the provision and use of efficient circulation and utility systems.
6. 6.
  Promotes the health benefits of pedestrian-oriented places, including safe routes for walking, bicycling and other exercise.
C.
Within New Communities, the FBZD:
1. 1.
  Encourages walkable neighborhoods through networks of well-designed streets that are safe and secure for pedestrians and bicycles.
2. 2.
  Encourages appropriately scaled development that places services within a safe, comfortable walking distance of homes.
3. 3.
  Encourages and incubates local business activity and economic sustainability through community design.
4. 4.
  Promotes neighborhoods with quality housing that encourage a diversity of housing choices and accommodate diverse ages and incomes.
5. 5.
  Promotes neighborhood form that facilitates the provision and use of efficient circulation and utility systems.
6. 6.
  Integrates civic, institutional, and other services into the fabric of communities. In areas designated for the location of schools, schools should be encouraged to be of size and location to enable children to walk or bicycle to them.
D.
Within Blocks and Buildings:
1. 1.
  Encourages that each building plays a role in creating a better whole, not just a good building.
2. 2.
  Encourages buildings and environments that can adapt to changing economics and demographics.
3. 3.
  Encourages that architecture and landscape grow from local climate, history, and building practice.
4. 4.
  Promote the placement of civic buildings in important locations and promote a form that reflects their civic stature.
5. 5.
  Promote building form that facilitates the provision and use of efficient utility systems.

Because the Charleston County FBZD only applies to rural areas of the County, this Ordinance allows the use of T-Zones T1 through T5 as well as Special Districts.

FIGURE 7.3.C: Settlement Type Diagram Examples
The following illustrative images describe the Charleston County Settlement Types that display a Community Unit or a group of Community Units located in general proximity with each other.
Crossroads. The smallest rural settlement type located at the intersection of two local roads. A crossroad is comprised of a compact cluster of homes about an intersection that is surrounded by countryside or agricultural lands. A corner store or civic use may mark the corner.	Corner. A rural settlement type that is larger than a crossroads and located at a significant crossroads or open space. A Corner is comprised of a compact cluster of homes organized in a walkable community with limited commercial services or civic uses, surrounded by countryside or agriculture.
Village. An urban settlement type organized into multiple walkable neighborhoods of compact clusters of various dwelling types, including mixed-use buildings, surrounded by countryside. A range of commercial services and civic activities provide for the daily needs of its residents. The population of a village is larger than in a corner but smaller than a town.	Towns. The most urban settlement type is an aggregation of walkable neighborhoods that mix residential, commercial, and civic uses. Located along or at the intersection of a major thoroughfare, the center provides for the daily need of its residents as well as those of visitors from around the region and thus accommodates the parking needs of local and transient users.

1. 2.
  Sectors Defined. Sectors are geographical areas that are comprised of 75% Acreage and growth areas. Growth areas are intended for the development of new settlements and communities in the form of Settlement Types and Community Types, which in turn are comprised of Transect Zones and Special Districts.

    (2).
    The Reserved Open Sector (O-2) shall consist of rural development patterns and activities and may include a mix of Separate Rural Development and open space.
    (3).
    The Restricted Growth Sector (G-1) shall be assigned to areas that have value as open space but are appropriate for development of restricted or limited intensity that is clustered.
    (4).
    The Controlled Growth Sector (G-2) shall be assigned to areas that can support a variety of mixed-use development patterns by virtue of proximity to existing infrastructure, including clustered land development and traditional neighborhood developments.
    (5).
    The Intended Growth Sector (G-3) shall be assigned to areas that can support substantial mixed-use development patterns by virtue of proximity to existing infrastructure, including traditional neighborhood developments and regional center developments.
2. 3.

This requirement shall not apply to Corner Settlements in the G-2 Sector.
2. Corners. Corners are larger settlement types than crossroads and are comprised of a compact cluster of up to 360 dwellings about a significant crossroads or open space, typically organized as a walkable district, surrounded by countryside or agricultural lands, with limited commercial services or civic activities. Historical patterns in the Lowcountry include the organization of corners associated with agricultural production, a religious group, or a family settlement. Corners in the G-2 Sector are comprised of a compact cluster of up to 500 dwellings.
3. Crossroads. Crossroads are the smallest settlement type and are comprised of a compact cluster of between 15 and 80 dwellings about a crossroads or intersection surrounded by countryside or agricultural lands, with limited commercial services or civic activities. Range of uses include corner stores, single family detached residences, and farms.
4. Rural Development. Rural areas may be composed of Separate Rural Development. Separate Rural Developments shall maintain rural densities and activities in a sparsely developed pattern.

Clustered Growth/Urban Places.

Villages. Villages are compact clusters of dwellings of mixed type, including mixed-use buildings, surrounded by undeveloped land, countryside or agricultural lands, organized into walkable neighborhoods, with a range of commercial services and civic activities that provide for the daily needs of its residents. The population of a village is larger than in a corner but smaller than a town.
Towns. Towns are larger than a village, an aggregation of walkable neighborhoods that mix residential, commercial, and civic uses, typically located along or at the intersection of a major thoroughfare. The town’s center provides for the daily need of its residents as well as those of visitors from around the region and thus accommodates the parking needs of local and transient users.
Towns provide adequate densities in support of frequent transit.

Settlements may be organized by Sector as described in Table 7.3.3.

TABLE 7.4.5-4: Private Frontages
The Private Frontage is the area between the building Facades and the Lot lines. (Table not subject to change by applicant)
	SECTION Lot > \| < R.O.W. Frontage \| Frontage	PLAN Lot > \| < R.O.W. Private > \| < Public Frontage Frontage
a. Common Yard: a planted Frontage wherein the Facade is set back substantially from the Frontage Line. The front yard created remains unfenced and is visually continuous with adjacent yards, supporting a common landscape. The deep Setback provides a buffer from the higher speed Thoroughfares.
b. Porch & Fence: a planted Frontage wherein the Facade is set back from the Frontage Line with an attached porch permitted to Encroach. A fence at the Frontage Line maintains street spatial definition. Porches shall be no less than 8 feet deep.
c. Terrace or Lightwell: a Frontage wherein the Facade is set back from the Frontage line by an elevated terrace or a sunken Lightwell. This type buffers Residential use from urban Sidewalks and removes the private yard from public Encroachment. Terraces are suitable for conversion to outdoor cafes. Syn: Dooryard.
d. Forecourt: a Frontage wherein a portion of the Facade is close to the Frontage Line and the central portion is set back. The Forecourt created is suitable for vehicular drop-offs. This type should be allocated in conjunction with other Frontage types. Large trees within the Forecourts may overhang the Sidewalks.
e. Stoop: a Frontage wherein the Facade is aligned close to the Frontage Line with the first Story elevated from the Sidewalk sufficiently to secure privacy for the windows. The entrance is usually an exterior stair and landing. This type is recommended for ground-floor Residential use.
f. Shopfront: a Frontage wherein the Facade is aligned close to the Frontage Line with the building entrance at Sidewalk grade. This type is conventional for Retail use. It has a substantial glazing on the Sidewalk level and an awning that may overlap the Sidewalk to within 2 feet of the Curb. Syn: Retail Frontage.
g. Gallery: a Frontage wherein the Facade is aligned close to the Frontage line with an attached cantilevered shed or a lightweight colonnade overlapping the Sidewalk. This type is conventional for Retail use. The Gallery shall be no less than 10 feet wide and should overlap the Sidewalk to within 2 feet of the Curb.
h. Arcade: a colonnade supporting habitable space that overlaps the Sidewalk, while the Facade at Sidewalk level remains at or behind the Frontage Line. This type is conventional for Retail use. The Arcade shall be no less than 12 feet wide and should overlap the Sidewalk to within 2 feet of the Curb.

TABLE 7.4.5-4: Private Frontages
The Private Frontage is the area between the building Facades and the Lot lines. (Table not subject to change by applicant)

The Arcade shall be no less than 12 feet wide and should overlap the Sidewalk to within 2 feet of the Curb.

TABLE 7.4.5-5: Building Disposition
This table approximates the location of the structure relative to the boundaries of each individual Lot, establishing suitable basic building types for each Transect Zone. (Table not subject to change by applicant)
a. Edgeyard: A building that occupies the center of its Lot with Setbacks on all sides. This is the least urban of types as the front yard sets it back from the Frontage, while the side yards weaken the spatial definition of the public Thoroughfare space. The front yard is intended to be visually continuous with the yards of adjacent buildings. The rear yard can be secured for privacy by fences and a well-placed Backbuilding and/or Outbuilding.
b. Sideyard: A building that occupies one side of the Lot with the Setback to the other side. A shallow Frontage Setback defines a more urban condition. If the adjacent building is similar with a blank side wall, the yard can be quite private. This type permits systematic climatic orientation in response to the sun or the breeze. If a Sideyard House abuts a neighboring Sideyard House, the type is known as a twin or double House. Energy costs, and sometimes noise, are reduced by sharing a party wall in this Disposition.
c. Rearyard: A building that occupies the full Frontage, leaving the rear of the Lot as the sole yard. This is a very urban type as the continuous Facade steadily defines the public Thoroughfare. The rear Elevations may be articulated for functional purposes. In its Residential form, this type is the Rowhouse. For its Commercial form, the rear yard can accommodate substantial parking.
d. Courtyard: A building that occupies the boundaries of its Lot while internally defining one or more private patios. This is the most urban of types, as it is able to shield the private realm from all sides while strongly defining the public Thoroughfare. Because of its ability to accommodate incompatible activities, masking them from all sides, it is recommended for workshops, Lodging and schools. The high security provided by the continuous enclosure is useful for crime-prone areas.
e. Specialized: A building that is not subject to categorization. Buildings dedicated to manufacturing and transportation are often distorted by the trajectories of machinery. Civic buildings, which may express the aspirations of institutions, may be included.

Community Plan Submittals - Standards. Subsequent Community Plan applications shall designate Transect Zones on a Regulating Plan, in accordance with the procedures for Community Plans in Sec. 7.2.3.B, Community Plans, and the following standards:
1. 1.
  Transition between Transect Zones. When applying Transect Zones, transitions between the T5, T4, and T3 Transect Zones are encouraged to occur within the block or across alleys but may occur across a street.
2. 2.
  Transect Organization. Transects shall be organized in a manner that responds appropriately to a site’s context. More intense Transect Zones shall be organized around neighborhood centers and neighborhood main streets in visible and accessible locations suitable for greater intensities, typically at or near the center of a Pedestrian Shed. Less intense Transect Zones shall generally be organized farther from the center and serve as a transition to natural and open space, and 75% Acreage.
3. 3.
  Transect Allocation. Community Plans for Community Units shall assign and map Transect Zones to each Pedestrian Shed according to the percentages allocated in Table 7.3.B, Sector/Settlement/Community Allocation.
