Lot averaging

  1. Lot averaging allows certain lot sizes to be reduced below the standard minimum if certain other lots are increased by the same size, as long as the resulting average lot size is not less than the stated minimum for that specific zoning district. The number of per-mitted dwelling units is usually not decreased, and common open space is not created. Lot averaging promotes design flexibility in order to avoid en-croachment into environmentally sensitive areas, or to preserve historic structures on larger lots.
