Minimum lot areas for such uses in each district shall be as set forth in Table 2, Summary of Dimensional Requirements, which is hereby made part of this Bylaw.

7.1.1 Contiguous Buildable Area (CBA)

As of April 28, 1986, the area of any new lot created, exclusive of area in a street or recorded way open to public use, at least seventy five (75) percent of the minimum lot area required for zoning shall be contiguous land other than land located within a line identified as wetland resource areas in accordance with the Wetlands Protection Act, Massachusetts General Laws, Chapter 131, Section 40 and the Town of North Andover Wetland Protection Bylaw, Chapter 178 of the Code of North Andover. The proposed structure must be constructed on said designated contiguous land area.

7.1.2 Lot Width

For any lot created after May 1, 1995, the minimum width of the lot shall be a distance of one hundred (100) feet between the street frontage and the front building line The width shall be measured in a line parallel to the street. This requirement shall apply in all zones except Residence 4 (R4) and Village Residential (VR); for zone R4, said minimum width of the lot shall be a distance of (eighty) 80 feet and for zone VR, said minimum width of the lot shall be a distance of (eighty) 80 feet.

7.1.3 Restrictions

1. When a fifty (50) foot straight line is drawn to divide a lot in two, and the perimeter of the smaller piece is greater than two hundred (200) feet, then such smaller piece shall not be included in the calculations when determining: lot area contiguous buildable area (CBA), or street frontage as required by the Summary of Dimensional Requirements (Table 2) of this bylaw. This restriction applies only to lots created after May 1, 1995.

2. Any lot created after May 1, 1995 shall have a lot depth of thirty (30) feet or more for at least eighty (80)percent of the minimum length of its frontage as required by the Summary of Dimensional Requirements (Table 2) of this bylaw. The lot depth shall be measured as a line drawn perpendicular to the street.

3. No lot, upon which is then located any buildings or with respect to which a permit has been issued and is then outstanding for the erection of any building, shall be subdivided or reduced in area in any manner unless said lot shall thereafter fulfill the lot area, street frontage and yard space requirements of this Bylaw except as may be permitted otherwise by the provisions of a variance granted by the Board of Appeals. If land be subdivided, conveyed, devised or otherwise transferred in violation hereof, no building permit or other permit shall be issued with reference to any of the land so transferred or to the lot(s) retained until all of such land and lots meet the requirements of this Zoning Bylaw. Any land taken by eminent domain or conveyed for a public purpose for which the land could have been taken shall not be deemed to be transferred in violation of the provisions hereof.

Minimum street frontage shall be as set forth in Summary of Dimensional Requirements (Table 2) and the lot line meeting these requirements shall constitute the "street frontage" for the lot. In no case shall actual street frontage at the street line be less than seventy five (75) feet; except as allowed by Section 7.2.2. Corner lots shall be required to have the required frontage only on one street. In determining the fulfillment of the minimum area and minimum street frontage of a lot required in any zoning district, there shall not be included any land within the limits of a street upon which such lot abuts, even if the fee to such street is in the owner of the lot; except that if a corner lot at its street corner is bounded in part by a segment of curved line not more than seventy five (75) feet in length connecting other lines bounding such lot which if extended would intersect, the area and frontage required in such lot shall be computed as if such potentially intersecting lines were so extended; but if a curved line more than seventy five (75) feet in length is the whole of any one boundary line of a lot, the minimum area and minimum frontage required shall be determined entirely within the lines bounding such lot, including such curved line.

7.2.1. Access across street frontage

Access to each lot, except for corner lots, must be provided across the street frontage. If access to a lot is not across the street frontage as of the date of the adoption of this Section 7.2.1, the lot will not be considered nonconforming as to use or as to an existing structure on that lot. (1994/39)

Exceptions to this requirement may be granted by the issuance of a Special Permit from the Planning Board. A street frontage access Special permit may be granted for a lot in any residential district provided that:

a) The specific site is an appropriate location for access to the lot given the current and projected traffic on the roadway, and the site distance to adjacent driveways and roadways, and/or

b) Special environmental conditions exit such as wetlands and/or steep slopes such that access across the street frontage would require wetland filling or extreme cutting and/or filling of slopes or would be otherwise detrimental to the environment,
