SECTION 6: MINIMUM LOT SIZE (3/10/1987)
6.1 The minimum lot size for all Subdivisions shall be based upon the following specifications and the "Minimum Lot Size By Soil Type" Table contained in the Appendix. The minimum lot sizes contained in the Table have been determined by soil characteristics of drainage, slope, parent material and specific restrictive features.
6.1.1 For the determination of the actual soil type(s) present, High Intensity Soil Maps shall be provided by the applicant for all Subdivisions. A High Intensity Soil Map is a map of a parcel of land being considered for development, on a perimeter survey, with a scale of one inch not to exceed one hundred (100) feet and contour intervals of two (2) feet or less, where soils are identified and mapped in accordance with “High Intensity Soil Maps for New Hampshire,” SSSNNE Special Publication Number 1 (as amended). High Intensity Soil Maps shall be prepared by field examination and stamped by a soil scientist certified by the State of New Hampshire Board of Natural Scientists (RSA 310-A).
6.1.2 Under special circumstances (including a Minor Subdivision), the Planning Board may allow the soils information contained in the Soil Conservation Service "Soil Survey of Carroll County" to be used, instead of a High Intensity Soil Map, for determining the soils present in the parcel proposed for some or all of the lots created by a Subdivision.
6.1.3 When more than one soil type is present in a parcel proposed for Subdivision, the maximum number of lots or Dwelling Units to be permitted on that parcel will be determined by summing the number of units permitted for each type of soil present in the parcel. The number of units permitted for a single type of soil is determined by dividing the area (in square feet) covered by the soil type by its minimum lot size obtained from the Minimum Lot Size By Soil Type Table in the Appendix.
This formula also applies to Cluster Single-Family Development and Multi-Family Residential Developments.
6.1.4 For residential developments with more than four bedrooms per unit, the minimum lot size shall be proportionately larger than the lot size indicated in the Minimum Lot Size By Soil Type Table, as determined by the formula:
Lot Size (in sq. ft.) = # of bedrooms/4 x Lot Size from Table
6.1.5 For Commercial Uses and/or industrial uses, the lot size shall be determined by the formula:
(Formula is based on loading rates listed in the N.H. Water Supply and Pollution Control Commission "Guide for the Design and Maintenance of Small Sewage Disposal Systems," January 1978, as amended.)
Lot sizes for Commercial and/or industrial uses shall not be less than the minimum stipulated by the Minimum Lot Size By Soil Type Table.
