(1) For the purpose of this section, small contracting businesses shall be deemed to include businesses engaged in construction and repair of buildings; installation and servicing of heating, cooling and electrical equipment, flooring, painting, plumbing, roofing and tiling; landscaping; and other such uses deemed by the zoning administrator to be similar in terms of type, scale and impact. This section shall not be construed to necessitate a use permit for offices of such businesses as authorized and conducted in accordance with the provisions established in sections 24.1-281 and 24.1-282 nor shall this section be construed to provide opportunities for business operations which involve on-site manufacturing of products or materials utilized in the conduct of such business.

(2) All structures, parking and loading areas, and storage areas associated with such use shall be located at least one hundred feet (100') [30m] from any lot line. Such setback and buffer area shall be landscaped and fenced in order to provide immediately a Type 50 transitional buffer.

(3) Not more than two (2) vehicles and pieces of equipment associated with the operation of a business shall be operated from the site or stored there overnight, unless a greater number is deemed appropriate and is authorized by the board of supervisors in conjunction with consideration of a special use permit application. Small transportable equipment including lawn mowers; chain saws; power hand tools; table, band or radial arm saws; and similar items shall not be included in such a determination.

(4) Unless otherwise stipulated by the board in granting a special use permit, the areas covered by all structures used primarily in connection with such uses shall not exceed a total of one thousand five hundred (1,500) square feet [135m²].

(5) Unless otherwise stipulated by the board in granting a special use permit, the area covered by any outdoor storage associated with such use shall not exceed a total of one thousand (1,000) square feet [90m²].

(6) All parking, loading and storage associated with such use shall be screened effectively from view from adjacent properties by landscaping and appropriate wooden or masonry fencing materials.

(7) The board shall find and determine that the proposed small contracting business is not likely to generate traffic, including commercial delivery vehicles, in greater volume than would normally be expected in the district in which it is located.

(8) The board shall find and determine that the proposed small contracting business is not likely to create noise, dust, vibration, odor, smoke, glare, electrical interference, fire hazard or any other hazard or nuisance to any greater or more frequent extent than would normally be expected in the district in which it is located.

(d) Docking workboats and off-loading seafood in RR and RC districts.

(1) Such uses may be authorized only on property which is classified RC or RR. The docking of workboats and the conduct of a waterman's operation shall be limited to occupants of the premises.

(2) No admission, dockage, or wharfage fees shall be charged.

(3) On-premises wholesale or retail sale of seafood shall be prohibited.

(4) Outdoor storage of goods, equipment, or materials (other than the workboat itself) shall be limited to a total of one thousand (1,000) square feet [90m²] and shall not be located in any front or side yard, or within twenty feet (20') [6m] of any property line. Any equipment or storage located on the property shall be screened from view from all public streets and adjacent properties by a landscaped buffer area supplemented, if determined necessary by the zoning administrator or the board at the time of permit approval, by masonry or wooden fencing material. In its approval of a special use permit, the board may limit outdoor storage to less than one thousand (1,000) square feet [90m²] or may require a setback greater than twenty feet (20') [6m] if deemed necessary based on the characteristics of the subject site or its surroundings.

(5) Repair of workboats shall be limited to routine maintenance, which may include:

a. minor tune-ups;

b. change of oil and filters;

c. washdown and drainage of workboats;

d. winterizing (draining lines, etc.);

e. other customary routine repairs or maintenance.

(6) All federal, state and local requirements for docking facilities shall be met and the necessary permits obtained prior to the issuance of a building permit for docks, piers, or boat houses.

(7) The workboats and seafood unloading operations shall be conducted in such a manner as to prevent potentially offensive odors from being produced. No overnight storage of seafood waste shall be permitted on the property.

(8) Any outdoor or security lighting shall be shielded so that glare is not directed onto adjacent property.

(9) The number of workboats docked at the property shall not exceed the capacity of the pier or boat house. The "rafting" of boats shall not be permitted.

(10) No heavy trucks shall be permitted to operate from the property.

(11) Any demand for parking generated by the conduct of such use shall be accommodated off the street.

(12) No bulk fuel storage in excess of twenty-five (25) gallons [95l] for dispensing into a workboat shall be permitted. The storage and utilization of toxic substances shall be limited to types and quantities that would customarily be utilized or stored for residential use. Any storage or utilization of combustible, toxic, or flammable substances shall be in accordance with the National Fire Prevention Code.

(13) The board shall, on a case-by-case basis, review and impose such other conditions as it deems necessary and appropriate to assure that the use will be compatible with, and will not adversely impact, adjoining properties and the environment of the area. Such conditions and restrictions may include:

a. hours of operation;

b. number of workboats permitted to use the private residential pier or dock;

c. a requirement to prepare a water quality impact assessment;

d. additional screening or landscaping requirements for outdoor storage areas and equipment.

(e) Home occupations with non-resident employees.

The allowable number of non-resident employees shall be specified in the use permit approval.

(2) Evaluation of this allowance shall be based on the general provisions of section 24.1-281 and applicable requirements as set forth in section 24.1-283.

(3) The term of any use permit issued under the provisions of this section shall be for two (2) years or such other specific time period (either lesser or greater) as may be deemed appropriate by the board. Nothing in this section shall be construed to prevent the operator of the home occupation from applying for a new permit prior to or after expiration of the initial permit.

(f) Enlargement or expansion of permitted home occupations.

(1) The board may authorize by special use permit issued in accordance with the procedures stipulated in article I, enlargements or expansion of home occupations permitted in sections 24.1-282 and 24.1-283.

(2) The board shall find that the overall spirit and intent of section 24.1-281 will not be violated by the issuance of a special use permit authorizing an enlargement or expansion and may attach any conditions deemed necessary to ensure such compliance.
