H. 
BC Business Corridor Overlay District.
(1) 
Purpose. The Town of Marlborough is bisected along a north-to-south axis comprising New York State Route 9W, which parallels the Hudson River. Historically, the Route 9W corridor has served the Town of Marlborough as both a significant transportation facility and the location of mixed residential, commercial, and light industrial land uses. There are various zoning district designations along the Route 9W corridor, including the HD, R, C-1, R-1, and R-Ag-1 districts. Within the areas of the Route 9W corridor which are zoned R-1 or R-Ag-1, there exist various improved or unimproved parcels with frontage on the state highway and which are currently, or previously have been, devoted to use for commercial or light industrial activities of the type which are currently allowable within the HD Zoning District. Some of the existing structures are devoted to commercial or light industrial activities as nonconforming uses in the R-1 or R-Ag-1 Zones. Some of these existing structures are not currently put to commercial or light industrial uses, and may be devoted to residential uses which, nonetheless, exist as meaningful opportunities for readaptation to commercial or light industrial uses for the benefit of public commerce and the generation of municipal revenues for the community, depending upon the content and nature of a specific concept plan of development. The Town Board concludes that a Business Corridor Overlay District, in the nature of a floating zone, is an appropriate device to encourage readaptation of existing structures, business use of unimproved parcels, or to eliminate nonconformities of active uses, within eligible properties within the Route 9W corridor.
(2) 
The Business Corridor Overlay District is a floating zone which may be established through the exercise by the Town Board of the procedures stated herein with respect to properties located within eligible areas along the transportation corridor of Route 9W in the Town of Marlborough, as such areas of eligibility are more particularly defined within Subsection H(3).
(3) 
Eligible areas. Parcels located within the R-1 or R-Ag-1 Zoning Districts within the Town of Marlborough are eligible locations for establishment of a Business Corridor Overlay District if they a) enjoy highway frontage useable for access to and from Route 9W, and b) are within 250 feet of the right of way line of New York State Route 9W and are currently devoted to, or were previously devoted to, residential, commercial or light industrial use and which are deemed an acceptable site for corridor overlay districting by the Town Board in order to implement a specific concept plan of development for commercial or light industrial activity.
(4) 
Permitted uses. In the event that the Town Board establishes a Business Corridor Overlay District designation, the principal permitted uses, the permitted accessory uses, and the permitted special uses of the property shall be those uses which are allowable within the HD Highway Development District. In the exercise of legislative discretion, the Town Board shall be entitled to establish such lot, height, yard, bulk, and area requirements as the Town Board finds to be appropriate to the circumstances of each particular development proposal. In the exercise of legislative discretion, the Town Board may authorize mixed uses on lands to be rezoned to BC in order to allow for the continuation of preexisting uses which might otherwise become nonconforming as a result of the zoning change. Notwithstanding the foregoing, new and used car sales, and adult entertainment uses, shall be prohibited in a BC District.
(5) 
Procedure for establishment.
(a) 
Petitions for the establishment of a Business Corridor Overlay District by amendment of the Zoning Map shall be made in writing to the Town Board. Applications shall be made by the owner or owners of the land proposed to be included in such district or by a person or persons possessing written contract or option rights to purchase such lands. In the event that an application is made by a person or persons holding contract or option rights to purchase the lands, the application shall be accompanied by a statement signed by the owner or owners granting authority on the part of such applicant to make the application. Upon submission of a complete application, the Town Board shall refer the application to the Planning Board for recommendation.

[1] 
In its review of the application, the Town Board may suggest such changes in the conceptual development plan as are found to be necessary or desirable by the Town Board in order to meet the standards of this § 155-12H. The Town Board may notify the applicant of such changes and may discuss such changes with the applicant. The suggestion of changes by the Town Board shall not constitute a waiver of its legislative discretion to reject or deny the rezoning application.
[2] 
The Town Board may reject the application at any time.
(d) 
Planning Board review.
[1] 
Upon the Town Board's satisfaction with the conceptual development plan, and upon the receipt of a request from the Town Board, the Planning Board shall review the project for purposes of site plan or special permit approvals, as such approvals may be required for the particular project under the regulations pertaining to the HD Highway Development district. Upon the filing of complete application documents for site plan or special permit approval as otherwise set forth in this chapter, the Planning Board shall schedule and hold a public hearing. It is anticipated that, as between the Planning Board and the Town Board, the Planning Board may serve as lead agency pursuant to the New York State Environmental Quality Review Act.
[2] 
In the event that the Planning Board approves the application for site plan approval or special permit, as the case may be, the Planning Board shall condition the approval upon the Town Board's amendment of the Zoning Map[1] by local law to establish a Business Corridor Overlay Zone designation for the subject property.
[1]
Editor's Note: The Zoning Map is included in a pocket at the end of this volume.

Editor's Note: The Zoning Map is included in a pocket at the end of this volume.
(f) 
Criteria for rezoning by the Town Board to Business Corridor Overlay District. In determining whether or not to amend the Zoning Map to establish a BC District, the Town Board shall consider, together with the intent and objectives of this section, whether the proposed district and development plan meet the following criteria:
[1] 
How the site shall be served by potable water and sanitary sewer facilities, and whether such facilities will be adequate to accommodate any additional demand placed upon them by the proposed development or readaptation;
[2] 
Whether the site is well drained, and stormwater generated by development of the site shall not place an undue burden on existing facilities or contribute to downstream flooding;
[3] 
Whether the site is located in an area suitable for the proposed elimination of nonconformity or readaptation of buildings and site development so as to be reasonably free of objectionable conditions such as odors, noise, dust, air pollution, traffic volumes beyond the capacity of the existing road system or proposed road improvements, and other environmental constraints;
[4] 
The site shall be located in a manner that allows access to the site from a public street with adequate site distances and that meets current engineering standards of the Town;
[5] 
The architectural style of any proposed readaptation or modification of development and exterior materials, finish and color shall be consistent with the character of nearby properties;
[6] 
The readaptation or modification of the site shall not produce undue adverse effects on the surrounding neighborhood;
[7] 
The extent to which the scope and design of the project will establish a worthwhile asset for this segment of the community and the community as a whole.
(g) 
Time limit on validity of rezoning. Any zoning permitted by this section shall be null and void and the zoning of the parcel shall revert back to its original zoning classification by a ministerial designation on the Zoning Map[3] by the Town Clerk, when directed by the Town Board, unless actual construction, pursuant to an approved site plan and a valid building permit is commenced within two years from the date of adoption by the Planning Board of a resolution of site plan approval following the rezoning.

A. 
Purpose. The purpose of allowing mixed uses is to encourage the establishment of commercial and business entities that are compatible in nature and allowed in the designated zone without the necessity of creating smaller individual lots.
B. 
Mixed uses allowed. Mixed uses on a single parcel of land shall be allowed in all zones. Uses may be mixed among those uses considered compatible according to the following list.
C. 
Applicability, uses must be allowed by current zoning. Mixed uses must meet all density requirements as if individual uses and must be either principal permitted or special uses within the designated zone. The applicability of these uses does not supersede restrictions placed on uses within the zones, i.e., a combination of uses may be allowed only if those uses are allowed as separate entities within the zone as described in § 155-12 (Use regulations).
D. 
Special use. Mixed uses shall be considered a special use and subject to Planning Board approval.

(1) 
For lots having both on-site water supply and waste disposal systems, a minimum usable area of 12,500 square feet.
(2) 
For lots having on-site waste disposal systems but public water supply, a minimum usable area of 4,000 square feet.
B.
