The minimum lot size in any area shall be in accordance with the following:
Public water and sewer. Residential lots served by both public water and public sewer systems shall be 80 feet or more in width and 12,000 square feet or more in area.
Public water or sewer. Residential lots served by only one of public water or public sewer systems shall be 100 feet or more in width and 20,000 square feet or more in area.
No public water or sewer. Residential lots served by neither public water nor public sewer systems shall be 100 feet or more in width and 25,000 square feet or more in area.
Exceptions. Greater lot areas may be required where individual septic tanks or individual wells are used if the health officer determines that there are factors of drainage, soil condition or other conditions to cause potential health problems. The agent shall require that data from percolation tests are submitted as a basis for passing upon subdivisions dependent upon septic tanks as a means of sewage disposal.
In addition to the lot area and width requirements specified in § 171-29, lots shall be arranged in order that the following considerations are satisfied:
Shape. The lot arrangement, design and shape shall be such that lots will provide satisfactory and desirable sites for buildings, be properly related to topography and conform to the requirements of this chapter. Lots shall not contain peculiarly shaped elongations solely to provide necessary square footage of area which would be unusable for normal purposes.
Location. Each lot shall abut on a street dedicated by the subdivision plat, or on an existing publicly dedicated street, or on a street which has become public by right of use. If the existing streets are not 50 feet in width, the subdivider shall make provisions in the deeds to the lots for all buildings to be so constructed as to permit the widening by dedication of such roads or streets to a width of 50 feet.
Corner lots. Corner lots shall have extra width sufficient for maintenance of any required building lines on both streets as determined by the agent.
Side lines. Side lines of lots shall be approximately at right angles or radial to the street line.
Remnants. All remnants of lots below minimum size left over after subdividing of a tract must be added to adjacent lots or otherwise disposed of rather than allowed to remain as unusable parcels.
Separate ownership. Where the land covered by a subdivision includes two or more parcels in separate ownership and lot arrangement is such that a property ownership line divides one or more lots, the land in each lot so divided shall be transferred by deed to single ownership, simultaneously with the recording of the final plat. Such deed is to be deposited with the clerk of the court and held with the final plat until the subdivider is ready to record same, and they both shall be recorded together.
Business or industrial uses. Lots intended for business or industrial use shall be designed specifically for such purposes with adequate space set aside for off-street parking and delivery facilities.
Where created by the subdivision of land, all new blocks shall be of modern design and shall comply with the following general requirements:
Length. Generally, the maximum length of blocks shall be 1,200 feet and the minimum length of blocks upon which lots have frontage shall be 500 feet.
Width. Blocks shall be wide enough to allow two tiers of lots of minimum depth, except where fronting on major streets, unless prevented by topographical conditions or size of the property, in which case the agent may approve a single tier of lots of minimum depth.
Orientation. Where a proposed subdivision will adjoin a major road, the agent may require that the greater dimension of the block shall front or back upon such major thoroughfare to avoid unnecessary ingress or egress.
