(Ord. No. 2014-125, § 2, 9-23-2014; Ord. No. 2015-142, § 12, 10-13-2015)
The requirements of this section have resulted from a contextual study of building height and architectural patterns in the Old City Height District. The requirements of this section reflect the predominant building height trends of the areas to which they are applied, and reinforce the principles cited in the Downtown Plan, adopted in 1999, that higher structures be located along spine streets of the Peninsula, with heights of structures tapering down towards the waters' edges. The requirements of this Section are intended to clarify acceptable heights of buildings in areas of the Old City Height District, subject to the right of the Board of Architectural Review to adjust heights in limited circumstances when based on architectural merit and context.
General requirements:
1.
Heights shall be measured in stories or feet, as specified. Notwithstanding the foregoing, height shall be measured in feet in the following districts: 3X, 85/200, 85/125, 85/30, 100/30, 80/30, 55/30S, 55/30, 56/30V, 120/30, 50W, W and WP.
2.
For maximum height specified in feet, the measurement shall be taken from the highest curb elevation adjacent to the site to the highest point of the structure. Where heights are specified in stories, the measurement shall be taken from finished floor to finished floor.
3.
Notwithstanding Sec. 54-306 (5), new principal buildings within a VE or AE zone on the Flood Insurance Rate Map may have 2 stories over a first-floor structure that exceeds 6' in height, provided the first floor elevation does not exceed the elevation required to meet FEMA and City freeboard requirements.
4.
If a building is required to be raised per FEMA requirements, that same height shall be added to the maximum height allowed, up to a maximum of six (6) feet. This measurement shall be taken from the highest curb elevation.
5.
Existing structures shall be allowed to be elevated to meet FEMA and City freeboard requirements and exceed height limitations of this Chapter.
6.
Any area under a structure in excess of six feet shall be counted as a story.
7.
The BAR is empowered to require a downward adjustment of one-half story in the number of stories from the permitted number of stories in the applicable height district based on the predominate number of stories in the structure's immediate surroundings, as defined in Section 54-231.
8.
Floors shall be measured in the following manner:
Residential:
a.
The maximum height of any residential floor shall be 12 feet The BAR may grant a waiver up to 14 feet on the first or second floor, based on architectural merit and context. Any dimension above this shall constitute two stories.
b.
The minimum height of any residential floor shall not be less than 10 feet; however, there is no minimum height for floors in a one family dwelling , two family dwelling or one family attached dwelling .
c.
The BAR is empowered to require adjustments to floor heights, based on context of the structure with its immediate surroundings, as defined in Section 54-231.
Non-Residential:
d.
The maximum height of any nonresidential story shall be 20 feet. The BAR may grant a waiver up to 25 feet on the main floor based on architectural merit and context. Any dimension above this height shall constitute two stories.
e.
The minimum height of any nonresidential floor shall not be less than 12 feet, unless otherwise specified in Sec. 54.306.X.
f.
The BAR is empowered to require adjustments to floor heights, based on context of the structure with its immediate surroundings, as defined in Section 54-231 H.
9.
Half stories, as the top story of a building, shall be permitted as specified by height district, subject to the following restrictions.
For the purposes of this section, half stories on one-family dwellings, two-family dwellings, one-family attached dwellings, and accessory buildings to these building types within the Old City Height Districts shall be limited the space under a gable or hipped roof where the wall plates, or knee walls, on at least two opposite exterior walls shall not exceed two feet in height. The aggregate width of dormers on a half story shall not exceed 30% of the width of the exterior wall below the dormer(s).
Notwithstanding the definition for half story in Sec. 54-120, for purposes of this section, half stories on all other types of buildings may be either:
a.
A full story with a total floor area, including any covered exterior floor area under a roof, that does not exceed 50% of the conditioned floor area of the story immediately below the half story as illustrated in Figure 1 below, or
b.
A half story under a gable or hipped roof that complies with the restrictions for a half story on a one or two family dwelling described in the previous paragraph
Figure 1
10.
Building height to roof eave shall not exceed twice the building width of the primary façade of habitable space fronting the street as illustrated in Figure 2 below; provided the Board of Architectural Review may waive this provision based on architectural merit and context.
Figure 2
11.
There shall be no minimum building height requirement, unless required by the applicable height district as specified in Sectiohn 54-306.X.
12.
If any portion of a structure subject to the jurisdiction of the BAR is within fifty (50) feet of an existing structure rated "exceptional" (Group 1) or "excellent" (Group 2) on the Historic Architecture Inventory, adopted by Section 54-235, or a structure in the Landmark Overlay district, such portion of that structure shall not exceed the height of such existing structures unless approved by the Board of Architectural Review based on architectural merit and context.
13.
Additional buildings and additions to buildings that are subject to the jurisdiction of the BAR shall be subordinate in height, scale and mass to the primary building; provided this provision may be waived by the Board of Architectural Review when it deems such appropriate based on architectural merit and context or existing lot conditions. This provision does not apply to vertical additions to existing buildings. When appropriate, vertical additions must strive to be minimally visible with minimal impact on the character of the historic building and its context.
14.
Parking garages shall not exceed the height of the principal building on the site. Parking garages shall not be constrained by floor to floor height requirements, but stand-alone parking garages shall appear from the street to conform to the number of stories permitted in the height district in which it is located.
15.
In the height districts where additional height may be awarded on the basis of architectural merit and context, if the property is not subject to the jurisdiction of the Board of Architectural Review, the owner requesting the additional height must submit the plans to the Board of Architectural Review for review and approval. The property will not remain subject to the Board of Architectural Review purview after the request for additional height is reviewed. Any further request for additional height will trigger review by the Board of Architectural Review.
16.
An applicant seeking a height rezoning shall only be able to request a rezoning to the next higher height district, except for applicants seeking a rezoning to the Upper Peninsula Zoning district. Requests to rezone to a higher height district shall be evaluated, in part, on the context of the property, the character of the immediate area, street widths around the property, and whether the requested rezoning will be compatible with surrounding properties.
17.
Standalone Communication towers shall not exceed the maximum building height limits of districts that include a maximum height limit in feet, or a height limit equal to 14 feet per story for districts that are specified in stories.
18.
"Architectural merit" means a project that reflects exemplary architectural and urban design, utilizes the highest level of materials and finishes and contributes to the public realm, as outlined in the Board of Architectural Review Principles.
19.
Additional height for ornamental appurtenances and utilitarian appurtenances related to mechanical equipment or structural systems (such as elevator and stair towers, exhaust fans, HVAC and communication equipment) that exceed the maximum allowable height may be permitted by the Board of Architectural Review, based on architectural merit and context.
20.
Appurtenances shall not exceed nine (9) feet and shall be placed to the rear of side of a building where possible in order to minimize visibility from the public right of way.
21.
Mechanical equipment on a roof shall be visually screened from the street with parapets or other types of visual screens of the minimum height necessary to conceal the same. Density of screening should be adequate to sufficiently screen mechanical equipment.

In this district:
1.
FEMA Velocity Zone regulations impose significant restrictions on the developable volume of properties that fall within its influence, and are particularly restrictive regarding street-level development. The success of the traditional urban fabric of Charleston is highly dependent upon the activation of the public realm, and street-level uses are a key element of this activity. The 56/30V Height District is intended to encourage a continuation of Charleston's urban traditions by providing incentive for development of street-level activity within FEMA Velocity Zones.
2.
No part of a structure shall exceed the height of fifty-six (56) feet unless permitted as a result of the following clauses, nor shall any principal structure be lower than thirty (30) feet.
3.
Allowances for additional enclosed habitable space above fifty-six (56) feet but not to exceed a height of seventy (70) feet shall be permitted when the development in question provides for contributory occupation of the ground floor at the street frontage(s) of the property. Such contributory occupation must be designed to abide by FEMA requirements for development in Velocity Zones as approved by the city's Floodplain Administrator. For every square foot of approved contributory occupation of the ground floor, the development will be permitted an equivalent square foot of habitable space above fifty-six (56) feet, up to a limit of 25 percent of the total rooftop area. Contributory occupation is defined as any activity that is deemed by the Zoning Administrator to be consistent with and supportive of the goal of street-level activation within the FEMA V-Zone. Such activity might include, but is not limited to: outdoor dining (covered or open-air), temporary shops or merchant stands; manned vending carts; green spaces (physically open to the sky); building access stairs or lobbies, storefront displays, etc. In addition, the areas dedicated to contributory occupation must be located with a majority of its frontage on the street or public sidewalk, and must be specifically designed to support contributory occupation. Under no circumstances will parking, mechanical or storage areas be considered contributory occupation.

The shared parking analysis shall be based on the Urban Land Institute's (ULI) Shared Parking Model (latest edition). The analysis must be prepared and sealed by a registered engineer in the State of South Carolina with transportation expertise;
ii.
The shared parking analysis shall address the size and type of activities, the composition of tenants or, uses, the rate of turnover for proposed shared spaces, and the anticipated peak parking and traffic demands;
iii.
The shared parking analysis shall provide for no reduction in the number of handicapped spaces;
iv.
The shared parking analysis shall provide a plan to convert reserved space to required spaces;
v.
The shared parking analysis shall be approved by TRC prior to submittal, based on the feasibility and observations of the uses to share the parking due to their particular peak parking and trip generation characteristics;
vi.
Shared use parking approval shall only be valid for those uses as indicated in the study; and
vii.
If a parking reduction is approved under the provisions of this section, such approval shall be evidenced by the issuance of an order in the manner prescribed in Section 54-319.1., 54-319.2.
b.
Change in use. Should any of the approved uses as indicated in the approved shared parking analysis change, or should the Zoning Director or Department of Traffic and Transportation, or its successor, find that any of the conditions described in the approved shared parking analysis or parking reduction order no longer exist, the owner of record shall have the option of submitting a revised shared parking analysis in accordance with the standards of this section or of providing the number of spaces required for each use as if computed separately.
2.
Parking reduction order. If an application for shared parking is approved, such approval shall be evidenced in an order executed by the department and a consent to order executed by the applicant. The order shall state the number of parking spaces required to be provided, a legal description of the property where the parking is to be provided and the property served by the parking area and the conditions upon which the shared parking is approved. The parking reduction order shall only take effect upon the recordation of the order in the County Register of Deeds office at the expense of the applicant and filed with the department by applicant.
a.
The parking reduction order shall act as a restrictive covenant running with the land and be binding on any successors in interest or assigns of the property owner.
3.
If there is a failure of any condition contained in the parking reduction order, the owner of the property or agent shall:
a.
Apply for an amended parking reduction order. The application shall show that although the condition has failed, it does not adversely impact the character and integrity of surrounding properties or that additional conditions will be substituted for any failed condition. The department may require a new parking study as provided in subsection 1.a. to support the application.
b.
In the event the department agrees with the application, the department may approve the amendment to shared parking.
c.
When final, the amended order shall be prepared for execution and recording in the County Register of Deeds office at applicant's expense by the applicant.
d.
If the department determines that failure of the condition adversely impacts the character and integrity of surrounding properties, the owner will be required to comply with the condition or obtain a new parking reduction order in accordance with this section. Failure of a condition of a parking reduction order without approval of an amended or new parking reduction order as provided herein shall be a violation of the Zoning Ordinance.
4.
If a shared parking application includes the use of an off-site parcel owned by other than the applicant for parking or purposes related to parking, an off-site parking agreement in accordance with Section 54-319.2 will be required.
5.
A parking reduction order may be terminated by application of the owner of the property affected by the order to the department if it is shown that parking has been provided which meets the requirements of Article 3, Part 4 Off-street parking requirements, and the use no longer needs a parking reduction. A termination of the parking reduction order shall be executed by the department and recorded in the public records of the county at the applicant's expense. A copy of the recorded order shall be filed with the department by the applicant.

c.
All roots outside the protective barricade to be removed during development shall be severed clean and a two inch (2″) layer of mulch shall be applied over the surface of exposed roots during development.
d.
All pruning of protected trees and grand trees shall be done by a qualified tree service during development according to the National Arborists Association, Pruning Standards for Shade Trees.
(Ord. No. 2002-19, §§ 6, 7, 2-12-02)
a.
Tree Replacement Required.
1.
For existing trees, the Board of Zoning Appeals-Site Design is authorized to grant variances or special exceptions to allow their removal as specified in Section 54-327 and 54-329, and to require the planting of replacement trees of at least two and one-half inches (2½″) caliper measured at six inches (6″) above grade with the total caliper inches per removed tree not to exceed the amount specified in Section 54-331.b.
2.
For trees removed unlawfully, without approval, the Board of Zoning Appeals-Site Design is authorized to grant after-the-fact approval, and require mitigation for trees removed with replacement trees of at least two and one-half inches (2½″) caliper measured at six inches (6″) above grade. The total caliper inches, type and size of replacement trees required by the Board shall be based on the health and specimen quality of the tree(s) removed, the site specific conditions, and the factual circumstances under which the tree was removed. For trees removed unlawfully from a single-family zoned lot or a lot used exclusively for a single-family home, the Board is authorized to require up to three (3) times the total D.B.H. of the tree(s) removed in caliper inches of replacement trees and the minimum size of the replacement trees to be planted on-site shall be four inches (4″) caliper. For trees removed unlawfully from all other properties, the Board is authorized to require up to ten (10) times the total D.B.H. of the tree(s) removed in caliper inches of replacement trees and the minimum size of the replacement trees to be planted on-site shall be four inches (4″) caliper.
3.
In all cases, the Board is authorized to require up to fifty (50) percent of the total caliper inches of replacement trees to be planted off-site at a location in the general area of where the tree removal(s) occurred, and to allow off-site replacement to be accomplished through a contribution to the City of Charleston Street Tree Planting Program in an amount equivalent to the City's cost for the type, size and number of trees to be planted off-site.
4.
In certain circumstances, the Board may require mitigation for trees removed in the form of specific arboricultural services to be rendered to remaining trees on the site.
b.
Mitigation Requirements. The Board is authorized, upon the granting of a variance or special exception for removal of a grand tree, to require mitigation with replacement trees. The total caliper inches per removed tree shall not exceed the amount specified below for the tree species being removed. Tree species are categorized by ratings taken from the Tree Species Rating Guide (March 2001), developed by the Southern Chapter of the International Society of Arboriculture. The categories below list tree species by their lowest rating in the range for hardiness zone 8. The category for species not listed below will be determined by using the Tree Species Rating Guide.
c.
Relocation of a Protected Tree. Relocation is accomplished by relocating the protected tree on land under the same ownership which is to be developed pursuant to the same development order.
d.
Replacement. Replacement is accomplished by planting the number, size and species of a recommended tree in accordance with the conditions at the Board of Zoning Appeals—Site Design, on land under the same ownership which is to be developed pursuant to the same development permit, within the right-of-way adjacent to the property subject to the approval of the appropriate government agency, or off-site within the general area of the trees being replaced.
e.
Tree Planting Requirements. In the relocation of a protected tree, or the replacement of a protected tree or grand tree with a recommended tree, the following planting criteria shall be met:
1.

4.
Seventy-five percent (75%) of the recommended trees shall be of those species which will provide similar or better wildlife habitat, shade, erosion control or water purification as the existing species.
f.
Inspection of Protected, Relocated or Replaced Trees. All relocated or replaced trees shall be inspected by the Zoning Administrator one (1) year after their planting to insure they are surviving in a healthy condition. Trees planted pursuant to this section that are found to be in declining condition shall be replaced by the owner of the parcel within thirty (30) days of notification from the Zoning Administrator. If replacement is necessary, there shall be a re-inspection six (6) months after the replacement planting.
g.
Maintenance of Protected, Relocated or Replaced Trees. The owner of the parcel shall be responsible for the maintenance of all protected, grand, relocated or replaced trees.

(Ord. No. 2014-125, § 2, 9-23-2014; Ord. No. 2015-142, § 12, 10-13-2015)
The requirements of this section have resulted from a contextual study of building height and architectural patterns in the Old City Height District. The requirements of this section reflect the predominant building height trends of the areas to which they are applied, and reinforce the principles cited in the Downtown Plan, adopted in 1999, that higher structures be located along spine streets of the Peninsula, with heights of structures tapering down towards the waters' edges. The requirements of this Section are intended to clarify acceptable heights of buildings in areas of the Old City Height District, subject to the right of the Board of Architectural Review to adjust heights in limited circumstances when based on architectural merit and context.
General requirements:
1.
Heights shall be measured in stories or feet, as specified. Notwithstanding the foregoing, height shall be measured in feet in the following districts: 3X, 85/200, 85/125, 85/30, 100/30, 80/30, 55/30S, 55/30, 56/30V, 120/30, 50W, W and WP.
2.
For maximum height specified in feet, the measurement shall be taken from the highest curb elevation adjacent to the site to the highest point of the structure. Where heights are specified in stories, the measurement shall be taken from finished floor to finished floor.
3.
Notwithstanding Sec. 54-306 (5), new principal buildings within a VE or AE zone on the Flood Insurance Rate Map may have 2 stories over a first-floor structure that exceeds 6' in height, provided the first floor elevation does not exceed the elevation required to meet FEMA and City freeboard requirements.
4.
If a building is required to be raised per FEMA requirements, that same height shall be added to the maximum height allowed, up to a maximum of six (6) feet. This measurement shall be taken from the highest curb elevation.
5.
Existing structures shall be allowed to be elevated to meet FEMA and City freeboard requirements and exceed height limitations of this Chapter.
6.
Any area under a structure in excess of six feet shall be counted as a story.
7.
The BAR is empowered to require a downward adjustment of one-half story in the number of stories from the permitted number of stories in the applicable height district based on the predominate number of stories in the structure's immediate surroundings, as defined in Section 54-231.
8.
Floors shall be measured in the following manner:
Residential:
a.
The maximum height of any residential floor shall be 12 feet The BAR may grant a waiver up to 14 feet on the first or second floor, based on architectural merit and context. Any dimension above this shall constitute two stories.
b.
The minimum height of any residential floor shall not be less than 10 feet; however, there is no minimum height for floors in a one family dwelling , two family dwelling or one family attached dwelling .
c.
The BAR is empowered to require adjustments to floor heights, based on context of the structure with its immediate surroundings, as defined in Section 54-231.
Non-Residential:
d.
The maximum height of any nonresidential story shall be 20 feet. The BAR may grant a waiver up to 25 feet on the main floor based on architectural merit and context. Any dimension above this height shall constitute two stories.
e.
The minimum height of any nonresidential floor shall not be less than 12 feet, unless otherwise specified in Sec. 54.306.X.
f.
The BAR is empowered to require adjustments to floor heights, based on context of the structure with its immediate surroundings, as defined in Section 54-231 H.
9.
Half stories, as the top story of a building, shall be permitted as specified by height district, subject to the following restrictions.
For the purposes of this section, half stories on one-family dwellings, two-family dwellings, one-family attached dwellings, and accessory buildings to these building types within the Old City Height Districts shall be limited the space under a gable or hipped roof where the wall plates, or knee walls, on at least two opposite exterior walls shall not exceed two feet in height. The aggregate width of dormers on a half story shall not exceed 30% of the width of the exterior wall below the dormer(s).
Notwithstanding the definition for half story in Sec. 54-120, for purposes of this section, half stories on all other types of buildings may be either:
a.
A full story with a total floor area, including any covered exterior floor area under a roof, that does not exceed 50% of the conditioned floor area of the story immediately below the half story as illustrated in Figure 1 below, or
b.
A half story under a gable or hipped roof that complies with the restrictions for a half story on a one or two family dwelling described in the previous paragraph
Figure 1
10.
Building height to roof eave shall not exceed twice the building width of the primary façade of habitable space fronting the street as illustrated in Figure 2 below; provided the Board of Architectural Review may waive this provision based on architectural merit and context.
Figure 2
11.
There shall be no minimum building height requirement, unless required by the applicable height district as specified in Sectiohn 54-306.X.
12.
If any portion of a structure subject to the jurisdiction of the BAR is within fifty (50) feet of an existing structure rated "exceptional" (Group 1) or "excellent" (Group 2) on the Historic Architecture Inventory, adopted by Section 54-235, or a structure in the Landmark Overlay district, such portion of that structure shall not exceed the height of such existing structures unless approved by the Board of Architectural Review based on architectural merit and context.
13.
Additional buildings and additions to buildings that are subject to the jurisdiction of the BAR shall be subordinate in height, scale and mass to the primary building; provided this provision may be waived by the Board of Architectural Review when it deems such appropriate based on architectural merit and context or existing lot conditions. This provision does not apply to vertical additions to existing buildings. When appropriate, vertical additions must strive to be minimally visible with minimal impact on the character of the historic building and its context.
14.
Parking garages shall not exceed the height of the principal building on the site. Parking garages shall not be constrained by floor to floor height requirements, but stand-alone parking garages shall appear from the street to conform to the number of stories permitted in the height district in which it is located.
15.
In the height districts where additional height may be awarded on the basis of architectural merit and context, if the property is not subject to the jurisdiction of the Board of Architectural Review, the owner requesting the additional height must submit the plans to the Board of Architectural Review for review and approval. The property will not remain subject to the Board of Architectural Review purview after the request for additional height is reviewed. Any further request for additional height will trigger review by the Board of Architectural Review.
16.
An applicant seeking a height rezoning shall only be able to request a rezoning to the next higher height district, except for applicants seeking a rezoning to the Upper Peninsula Zoning district. Requests to rezone to a higher height district shall be evaluated, in part, on the context of the property, the character of the immediate area, street widths around the property, and whether the requested rezoning will be compatible with surrounding properties.
17.
Standalone Communication towers shall not exceed the maximum building height limits of districts that include a maximum height limit in feet, or a height limit equal to 14 feet per story for districts that are specified in stories.
18.
"Architectural merit" means a project that reflects exemplary architectural and urban design, utilizes the highest level of materials and finishes and contributes to the public realm, as outlined in the Board of Architectural Review Principles.
19.
Additional height for ornamental appurtenances and utilitarian appurtenances related to mechanical equipment or structural systems (such as elevator and stair towers, exhaust fans, HVAC and communication equipment) that exceed the maximum allowable height may be permitted by the Board of Architectural Review, based on architectural merit and context.
20.
Appurtenances shall not exceed nine (9) feet and shall be placed to the rear of side of a building where possible in order to minimize visibility from the public right of way.
21.
Mechanical equipment on a roof shall be visually screened from the street with parapets or other types of visual screens of the minimum height necessary to conceal the same. Density of screening should be adequate to sufficiently screen mechanical equipment.

In this district:
1.
FEMA Velocity Zone regulations impose significant restrictions on the developable volume of properties that fall within its influence, and are particularly restrictive regarding street-level development. The success of the traditional urban fabric of Charleston is highly dependent upon the activation of the public realm, and street-level uses are a key element of this activity. The 56/30V Height District is intended to encourage a continuation of Charleston's urban traditions by providing incentive for development of street-level activity within FEMA Velocity Zones.
2.
No part of a structure shall exceed the height of fifty-six (56) feet unless permitted as a result of the following clauses, nor shall any principal structure be lower than thirty (30) feet.
3.
Allowances for additional enclosed habitable space above fifty-six (56) feet but not to exceed a height of seventy (70) feet shall be permitted when the development in question provides for contributory occupation of the ground floor at the street frontage(s) of the property. Such contributory occupation must be designed to abide by FEMA requirements for development in Velocity Zones as approved by the city's Floodplain Administrator. For every square foot of approved contributory occupation of the ground floor, the development will be permitted an equivalent square foot of habitable space above fifty-six (56) feet, up to a limit of 25 percent of the total rooftop area.

Parking spaces required for one use shall not be used to satisfy the parking requirement for another use with the exception of churches, synagogues or other places of worship. Additional parking for bicycles shall be required for certain land uses pursuant to Section 54-320. For the purposes of this Section, "peninsula" shall mean the area of the City of Charleston bounded by the Cooper River to the east, the Ashley River to the west and south, and the Charleston City Limits to the north.
b.
Maximum area of paved parking spaces and aisles allowed for surface parking lots. The maximum number of hard surfaced parking spaces allowed for a shopping center development, as defined in Table 3.3, shall not exceed the total number of spaces required pursuant to this section, increased by 20 percent. All spaces and appurtenant aisles in excess of this 20 percent cap, or areas within the parking lot equivalent in size to the number of excess parking spaces multiplied by 450 square feet, shall be non-hard surfaced utilizing slag, gravel, ROC, grasscrete, or similar porous material or simply a grass field.

The Technical Review Committee (TRC) may authorize a parking reduction for a new development site or redevelopment site zoned General Business (GB) with multiple uses upon the review of a shared parking analysis that demonstrates that the uses are in close proximity to one another and have different peak parking demands and operating hours. For the purposes of this section, development site shall mean a lot or parcel of land or combination of lots or parcels of land proposed for development. If a development site has more than one (1) parcel or lot with different owners, all property owners will be required to sign the application for shared parking, and shall be required to execute and record in the public records a declaration on a form provided by the Department of Planning and Preservation, hereinafter department, stating that the parcels have been developed as a single unit for purposes of meeting the zoning ordinance requirements. The declaration shall include a legal description of each parcel and shall state that no parcel may be developed separate from the other parcel unless each parcel standing alone meets the requirements of the shared parking approval.
a.
Shared parking study. The shared parking analysis shall clearly identify the uses that will use the shared spaces at different times of the day, week, month or year subject to the following:
i.
The shared parking analysis shall be based on the Urban Land Institute's (ULI) Shared Parking Model (latest edition). The analysis must be prepared and sealed by a registered engineer in the State of South Carolina with transportation expertise;
ii.
The shared parking analysis shall address the size and type of activities, the composition of tenants or, uses, the rate of turnover for proposed shared spaces, and the anticipated peak parking and traffic demands;
iii.
The shared parking analysis shall provide for no reduction in the number of handicapped spaces;
iv.
The shared parking analysis shall provide a plan to convert reserved space to required spaces;
v.
The shared parking analysis shall be approved by TRC prior to submittal, based on the feasibility and observations of the uses to share the parking due to their particular peak parking and trip generation characteristics;
vi.
Shared use parking approval shall only be valid for those uses as indicated in the study; and
vii.
If a parking reduction is approved under the provisions of this section, such approval shall be evidenced by the issuance of an order in the manner prescribed in Section 54-319.1., 54-319.2.
b.
Change in use. Should any of the approved uses as indicated in the approved shared parking analysis change, or should the Zoning Director or Department of Traffic and Transportation, or its successor, find that any of the conditions described in the approved shared parking analysis or parking reduction order no longer exist, the owner of record shall have the option of submitting a revised shared parking analysis in accordance with the standards of this section or of providing the number of spaces required for each use as if computed separately.
2.
Parking reduction order. If an application for shared parking is approved, such approval shall be evidenced in an order executed by the department and a consent to order executed by the applicant. The order shall state the number of parking spaces required to be provided, a legal description of the property where the parking is to be provided and the property served by the parking area and the conditions upon which the shared parking is approved. The parking reduction order shall only take effect upon the recordation of the order in the County Register of Deeds office at the expense of the applicant and filed with the department by applicant.

The parking reduction order shall act as a restrictive covenant running with the land and be binding on any successors in interest or assigns of the property owner.
3.
If there is a failure of any condition contained in the parking reduction order, the owner of the property or agent shall:
a.
Apply for an amended parking reduction order. The application shall show that although the condition has failed, it does not adversely impact the character and integrity of surrounding properties or that additional conditions will be substituted for any failed condition. The department may require a new parking study as provided in subsection 1.a. to support the application.
b.
In the event the department agrees with the application, the department may approve the amendment to shared parking.
c.
When final, the amended order shall be prepared for execution and recording in the County Register of Deeds office at applicant's expense by the applicant.
d.
If the department determines that failure of the condition adversely impacts the character and integrity of surrounding properties, the owner will be required to comply with the condition or obtain a new parking reduction order in accordance with this section. Failure of a condition of a parking reduction order without approval of an amended or new parking reduction order as provided herein shall be a violation of the Zoning Ordinance.
4.
If a shared parking application includes the use of an off-site parcel owned by other than the applicant for parking or purposes related to parking, an off-site parking agreement in accordance with Section 54-319.2 will be required.
5.
A parking reduction order may be terminated by application of the owner of the property affected by the order to the department if it is shown that parking has been provided which meets the requirements of Article 3, Part 4 Off-street parking requirements, and the use no longer needs a parking reduction. A termination of the parking reduction order shall be executed by the department and recorded in the public records of the county at the applicant's expense. A copy of the recorded order shall be filed with the department by the applicant.

a.
Protection of Grand Trees. The removal, relocation, destruction or abuse in any manner of any grand tree (24″ or greater D.B.H., excluding pine trees and sweetgum trees) is prohibited on any parcel of non-exempt land unless a variance, special exception, or staff approval has been obtained pursuant to Section 54-329. For subdivisions, the siting of a lot so as to place a grand tree at or near the center of a lot in a location that will require the removal of the grand tree for construction of a dwelling unit, shall be prohibited.
b.
Protected Trees Prior to Development. Where a building permit or subdivision approval has not been issued, the removal, relocation, destruction or abuse in any manner of more than twenty-five percent (25%) of the protected trees (8″ or greater D.B.H.) on any one (1) parcel of non-exempt land within any five (5) year period shall be prohibited. The total number of protected trees existing on any one parcel shall not be reduced below a total number equal to fifteen (15) protected trees per acre.
c.
Protected trees during or after development. The removal, relocation, destruction or abuse in any manner of protected trees required to be saved by this Chapter is prohibited. For parcels of land proposed for development, a minimum number of protected trees on the entire parcel equal to fifteen (15) protected trees per acre shall be saved. For parcels containing less than fifteen (15) protected trees per acre, the total number of protected trees required to be saved shall equal the total number of protected trees existing on the parcel. Grand trees to be saved may be used to calculate the total number of protected trees to be saved.
d.
Protection of Tree Colonnades and Allees. The removal, relocation, destruction or abuse in any manner of any protected tree within a colonnade or allee is prohibited on any parcel of non-exempt land. For the purpose of this ordinance, a colonnade or allee is defined as any two (2) or more parallel rows of trees of the same species with a minimum of four (4) trees total and a minimum of two (2) trees measuring twenty inches (20″) or greater D.B.H., except for pine trees and parallel rows of trees with a public right-of-way in the center which are exempt from this definition.
e.
This Ordinance shall not restrict the ability of the City of Charleston, public utilities, and electric suppliers from maintaining safe clearance around utility lines.
f.
The area of existing utility and drainage easements may be subtracted from the total site area for the purpose of calculating the number of protected trees required to be saved.
g.

a.
Tree Replacement Required.
1.
For existing trees, the Board of Zoning Appeals-Site Design is authorized to grant variances or special exceptions to allow their removal as specified in Section 54-327 and 54-329, and to require the planting of replacement trees of at least two and one-half inches (2½″) caliper measured at six inches (6″) above grade with the total caliper inches per removed tree not to exceed the amount specified in Section 54-331.b.
2.
For trees removed unlawfully, without approval, the Board of Zoning Appeals-Site Design is authorized to grant after-the-fact approval, and require mitigation for trees removed with replacement trees of at least two and one-half inches (2½″) caliper measured at six inches (6″) above grade. The total caliper inches, type and size of replacement trees required by the Board shall be based on the health and specimen quality of the tree(s) removed, the site specific conditions, and the factual circumstances under which the tree was removed. For trees removed unlawfully from a single-family zoned lot or a lot used exclusively for a single-family home, the Board is authorized to require up to three (3) times the total D.B.H. of the tree(s) removed in caliper inches of replacement trees and the minimum size of the replacement trees to be planted on-site shall be four inches (4″) caliper. For trees removed unlawfully from all other properties, the Board is authorized to require up to ten (10) times the total D.B.H. of the tree(s) removed in caliper inches of replacement trees and the minimum size of the replacement trees to be planted on-site shall be four inches (4″) caliper.
3.
In all cases, the Board is authorized to require up to fifty (50) percent of the total caliper inches of replacement trees to be planted off-site at a location in the general area of where the tree removal(s) occurred, and to allow off-site replacement to be accomplished through a contribution to the City of Charleston Street Tree Planting Program in an amount equivalent to the City's cost for the type, size and number of trees to be planted off-site.
4.
In certain circumstances, the Board may require mitigation for trees removed in the form of specific arboricultural services to be rendered to remaining trees on the site.
b.
Mitigation Requirements. The Board is authorized, upon the granting of a variance or special exception for removal of a grand tree, to require mitigation with replacement trees. The total caliper inches per removed tree shall not exceed the amount specified below for the tree species being removed. Tree species are categorized by ratings taken from the Tree Species Rating Guide (March 2001), developed by the Southern Chapter of the International Society of Arboriculture. The categories below list tree species by their lowest rating in the range for hardiness zone 8. The category for species not listed below will be determined by using the Tree Species Rating Guide.
c.
Relocation of a Protected Tree. Relocation is accomplished by relocating the protected tree on land under the same ownership which is to be developed pursuant to the same development order.
d.
Replacement. Replacement is accomplished by planting the number, size and species of a recommended tree in accordance with the conditions at the Board of Zoning Appeals—Site Design, on land under the same ownership which is to be developed pursuant to the same development permit, within the right-of-way adjacent to the property subject to the approval of the appropriate government agency, or off-site within the general area of the trees being replaced.
e.
Tree Planting Requirements. In the relocation of a protected tree, or the replacement of a protected tree or grand tree with a recommended tree, the following planting criteria shall be met:
1.
Each tree must be a minimum of two and one-half inches (2½″) caliper measured six inches (6″) above grade.
2.
All trees used shall be vigorous, well shaped, branched and foliated;
3.
All trees shall be planted in accordance with the specifications described in Section 1.94 of Erosion and Sediment Control Practices for Developing Areas by the South Carolina Land Resources Conservation Commission, Erosion and Sediment Control Division; and
4.
Seventy-five percent (75%) of the recommended trees shall be of those species which will provide similar or better wildlife habitat, shade, erosion control or water purification as the existing species.
f.
Inspection of Protected, Relocated or Replaced Trees. All relocated or replaced trees shall be inspected by the Zoning Administrator one (1) year after their planting to insure they are surviving in a healthy condition. Trees planted pursuant to this section that are found to be in declining condition shall be replaced by the owner of the parcel within thirty (30) days of notification from the Zoning Administrator. If replacement is necessary, there shall be a re-inspection six (6) months after the replacement planting.
g.
Maintenance of Protected, Relocated or Replaced Trees. The owner of the parcel shall be responsible for the maintenance of all protected, grand, relocated or replaced trees.

Buffers are landscaped areas of varying depths intended to separate and screen incompatible land uses from one another or provide green areas along major roadways and rivers, and in some instances, screen development entirely from roadways or rivers.
a.
Generally
1.
Buffers shall vary in depth and in landscaping requirements according to the zone district of the adjoining property or the classification of the adjacent road or river. (See attached road and river classification chart).
2.
Buffers shall be located along the perimeter of a lot or parcel and shall extend to the boundary line of the lot or parcel. Buffers shall not be located on any portion of an existing public or private street right-of-way. Where utility or drainage easements exist along property lines, the buffer shall be located adjacent to the easement and may be reduced by the width of the easement on the property where the buffer is required or twenty-five percent (25%) of the required buffer width, whichever is smaller.
3.
Buffers which are required pursuant to this Article shall be indicated as such on all plats of new and expanded developments.
4.
With the exception of the improvements as listed below in subsection 5., no new structures, impervious surfaces, unpaved vehicular use areas or other improvements shall hereafter be constructed within designated buffer areas.
5.
Sidewalks pursuant to Section 54-361, fences, gates, mailboxes, community boat ramps, necessary driveways, and permitted signs may be installed in designated buffer areas, subject to applicable permits.
b.
Non-conforming buffers. All developed lots and all undeveloped but recorded single-family house lots on (effective date) which do not comply with the buffer requirement of this section shall be grandfathered as legal non-conforming lots, except that existing landscaping on these legal non-conforming lots which satisfies, either partially or wholly, the buffer requirements of this Article, shall be required to be maintained.
c.
Schedule of required buffers. Table 3.5 shows the required buffers. Compliance of planted buffers will be evaluated on the basis of "Required Plantings per one Hundred Feet" as specified on buffer diagram text.
Existing vegetation may be combined with or substituted for new plant material in order to satisfy "Required Plantings per One Hundred Feet."
Where deemed appropriate by the Zoning Administrator, non-vegetative screening devices, including fences, walls and earthen berms may be substituted for a portion of the "Required Plantings per one Hundred Feet" in buffer types B, D, F, J and K.
d.
Exceptions.
1.
All properties located within the City limits on the peninsula of Charleston shall not require installation of landscape buffers along street frontages; and landscape buffers required pursuant to Table 3.5: Schedule of Required Buffers, to separate and screen incompatible uses, shall only be required to consist of a landscaping area with a minimum width of five (5) feet in which a wall of at least six (6) feet in height is placed and one (1) recommended non-deciduous tree is planted for each twenty-five (25) feet linear feet of landscaping area. For the purposes of this Section, "peninsula" shall mean the area of the City of Charleston bounded by the Cooper River to the east, the Ashley River to the west and south, and the Charleston City Limits to the north.
2.
Design Review District. In order to allow for new buildings to relate harmoniously with the streetscape and to other structures in the vicinity, when deemed appropriate by the Design Review Board, buildings may encroach into Class I Road Buffers (Buffer Type A), Class II Road Buffers (Buffer Type C), and Class VI Road Buffers (Buffer Type H).
