Provide suitable locations for selected establishments of highway-related functions, which are independent of primarily local use and proximity to other establishments. These are functions which require high mobility characteristics, i.e., prime accessibility conditions, ample off-street parking, desirable transient travel facilities and location within easy view of motorists on the major highway or parkway.

Provide a suitable location for large, planned combination local and regional uses which require high local and regional accessibility and large tracts of land not usually available in the Central Business District. However, where the development of such uses would pervert or subvert the goals of the Town Development Plan, or would promote urban sprawl, it should be discouraged.

Provide for the orderly development of the instant land in a proper use, while maintaining smooth and continuous traffic flow on the interchange and major roadways, without producing congestion on the local roads, thus protecting the proper functioning of the interchange and the local road net.

Promote the uses and types of development suitable to enhance the economic value and visual aspect of the gateway areas of the community without detracting from the neighboring areas.

To avoid cluttered, indiscriminate and mixed uses and to promote development which will visually be in harmony with and relate to the scale and function of the interchange.

Provide ample buffering and separation of these intended interchange uses from the existing or zoned surrounding development (further defined in § 300-154A(6) and (7).)

Minimum lot size and frontage. The site for each planned interchange district use shall be not less than 10 acres in area. Such site shall have a minimum frontage of at least 100 feet on a roadway whereupon entrance may be obtained from the appropriate jurisdictional authority.

The road frontage of 100 feet shall not be required for lots created as above.

Site coverage and floor area ratio. All principal and accessory buildings and structures on such site shall not cover more than 15% of the site. Outdoor swimming pools, outdoor restaurants, cabana areas and outdoor recreation sites, etc., shall be included in the site coverage computation, but not in the floor area ratio computation.

Chimneys and/or fire bulkheads may rise above this height as required by applicable regulations. For other exceptions to this height restriction, see Subsection A(5) below.

The design of the concealment shall be completely integrated with the appearance of the structure.

Building, structure and paved-area setbacks.

Buffering for adjacent properties.

Application of and computation of site coverage and floor area ratio.

However, the Town Board, in approving such site plan, may allow variances to the standards set forth in Article XX.

Exterior lighting shall be appropriate for the illumination levels recommended for the various components of the use. Design of the luminants shall be appropriate to the architectural appearance and landscaping of the installation. Luminants shall be shielded to prevent annoyance and spill over to adjacent properties or to highway users.
