Seabrook Island City Zoning Code

ARTICLE 12

PARKING AND LOADING

Section 12.1 - Purpose.

The purpose of this article is to prescribe regulations for off-street parking of motor vehicles in residential and non-residential zoning districts; to ensure by the provision of these regulations that adequate parking and access are provided in a safe and convenient manner; and to afford reasonable protection to adjacent land uses from light, noise, air/water pollution and other effects of PARKING LOT proximity.

Section 12.2 - General Requirements.

A.

Applicability of Parking Requirements. For all BUILDINGs and uses established after the effective date of this ordinance, off-street parking shall be provided as required by this article. In addition, the following shall apply:

1.

Whenever use of a BUILDING or LOT is changed to another classification of use, off-street parking facilities shall be provided, as required for that use.

2.

If the intensity of use of any BUILDING or LOT is increased, through the addition of floor area, increase in seating capacity, or other means, additional off-street parking shall be provided, as required by this article.

3.

Off-street parking facilities in existence on the effective date of this ordinance shall not be reduced below the requirements of this article, nor shall NONCONFORMING parking facilities be further reduced or made more NONCONFORMING.

4.

An area designated as required off-street parking shall not be changed to another use, unless equal facilities are provided elsewhere in accordance with the provisions of this article.

B.

Location. Off-street parking facilities required for dwellings shall be located on the same LOT or plot of ground as the dwelling they are intended to serve and shall consist of at least a driveway, parking strip, parking apron, or PARKING LOT. Off-street parking facilities required for all uses other than dwellings shall be located on the LOT or within 300 feet of the BUILDING(s) or use they are intended to serve, as measured from the nearest point of the parking facility to the nearest public entry of the BUILDING(s) or use served. Driveways shall not be located closer than six (6) feet to an adjacent property line, unless otherwise provided by this ordinance.

C.

Shared/Common Parking. Parking requirements may be modified where it can be shown that the hours of operation of two (2) or more businesses are such that they can share the same PARKING SPACEs (e.g., a RETAIL store or office that closes before a RESTAURANT in the same location opens.) The periods of peak use must not overlap and there must exist a written agreement between the parties involved providing for joint use of the spaces. A copy of such agreement shall be kept on file with the ZONING ADMINISTRATOR.

1.

A request for shared parking that will result in fewer than the total number of spaces required for all uses separately may be approved as part of SITE DEVELOPMENT PLAN review. The following documentation shall be provided in conjunction with such a request:

a.

A shared parking analysis, in a form established by or acceptable to the ZONING ADMINISTRATOR, shall be submitted to the ZONING ADMINISTRATOR demonstrating the feasibility of shared parking. It must address, at a minimum, the size and type of the proposed DEVELOPMENT or combination of uses, the composition of tenants, the hours of operation of the uses, and the peak hours of use if the hours of operation overlap.

b.

A shared parking plan shall be enforced through written agreement among all owners of record and included in the DEVELOPMENT agreements filed with the TOWN. The owner of the shared parking area shall enter into a written agreement with the TOWN with enforcement running to the TOWN. The agreement shall state that:

i.

The land comprising the parking area shall never be disposed of, except in conjunction with the sale of the BUILDING which the parking area serves so long as the facilities are required; and

ii.

The owner agrees to bear the expense of recording the agreement which shall bind his or her heirs, successors, and assigns.

2.

An attested copy of the shared parking agreement between the owners of record shall be submitted to the ZONING ADMINISTRATOR to be recorded in a form established by the TOWN attorney. The agreement must be recorded before issuance of a BUILDING permit or certificate of occupancy for any use to be served by the shared parking area. A shared parking agreement may only be revoked if all required off-street PARKING SPACEs will be otherwise provided on-site for all BUILDINGs or uses which are party to the agreement. The TOWN shall void the written agreement if other off-street facilities are provided in accordance with the provisions of this ordinance.

D.

Modification of Parking Requirements. The PLANNING COMMISSION may reduce the PARKING SPACE requirements of this article for any use, based upon a finding that one (1) or more of the following conditions shall be met. A parking study may be required, at the sole discretion of the PLANNING COMMISSION, to document conformance with one (1) or more of the following criteria:

1.

Bicycle or pedestrian travel is likely to be used and the site design will incorporate both bicycle parking facilities and pedestrian connections.

2.

Boat or other marine travel is likely to be used the site design will incorporate wet slips or dry dock storage with associated dock facilities and pedestrian connections.

3.

Shared parking is available to multiple uses where there will be a high proportion of multipurpose visits or where uses have peak parking demands during differing times of the day or days of the week and meeting the following requirements:

a.

Pedestrian connections shall be maintained between the uses.

b.

Unless the multiple uses are all within a unified BUSINESS CENTER or mixed-use DEVELOPMENT all under the same ownership, shared parking agreements shall be filed by the ZONING ADMINISTRATOR with the TOWN clerk after approval and recording.

4.

Available shared off-street parking or on-street spaces are located within 300 feet of the subject property.

5.

Expectation of walk-in trade is reasonable due to sidewalk connections to adjacent residential neighborhoods. To allow for a PARKING SPACE reduction, the site design shall incorporate pedestrian connections to the site and on-site pedestrian circulation, providing safe and convenient access to the BUILDING entrance.

6.

Where the applicant has provided a parking study, conducted by a qualified transportation engineer, demonstrating that another standard would be more appropriate based on actual number of employees, expected level of customer traffic, or actual counts at a similar establishment.

E.

Temporary Parking. It is recognized that there may be temporary events or situations that occur infrequently which would result in a temporary reduction in the availability of required PARKING SPACEs. Such events may include, but are not limited to, outdoor vehicle sales, festivals or fairs, charity car washes, or sporting events. In those instances, the ZONING ADMINISTRATOR may authorize the use of a portion of the required parking area for other purposes on a temporary basis or permit temporary parking, upon a demonstration by the applicant that:

1.

The loss of the required PARKING SPACEs may be offset by requiring employees or customers to park elsewhere or that due to the time of year or nature of the on-site business, the required spaces are not needed;

2.

All or part of the displaced parking may be accommodated on unpaved areas of the site;

3.

Neighboring property owners or operators have granted permission to use their parking facilities;

4.

The duration of the temporary event is so short or of such a nature as to not create any appreciable parking shortage for the normal operation of the existing on-site use;

5.

Temporary off-site parking is located and designed to ensure safe and efficient circulation for both pedestrians and vehicles (a SITE DEVELOPMENT PLAN may be required to demonstrate this); and

6.

The proposed temporary event satisfies all other applicable TOWN regulations.

Section 12.3 - Required Off-Street Parking.

The minimum number of required off-street PARKING SPACEs shall be provided and maintained on the premises or as otherwise allowed by this article, as specified in Table 12-3.

A.

When the calculation of required PARKING SPACEs result in a fraction over one-half (½),the number of required PARKING SPACEs shall be rounded up to the next full number.

B.

In the case of a use not specifically mentioned, the requirement for off-street parking facilities for a specified use which is most similar, as determined by the ZONING ADMINISTRATOR, shall apply.

C.

Each 24 inches of bench, pew, or similar seating facilities shall be counted as one (1) seat, except if specifications and plans filed in conjunction with a BUILDING permit application specify a maximum seating capacity, that number may be used as the basis for required PARKING SPACEs.

D.

Where parking requirements are based upon maximum seating or occupancy capacity, the capacity shall be as determined by the applicable fire and BUILDING CODES.

E.

Unless otherwise indicated, floor area shall be USABLE FLOOR AREA (UFA).
