Zoning

LD-3

Residential District

Development of the areas designated for the lowest density development is limited by the type of existing road access to the area, the unavailability of utilities and municipal services, and, most importantly, the lack of sewage disposal facilities. Experience has demonstrated that the soil and underground strata conditions have not supported individual sewage disposal systems on smaller lots. Residential development in these areas, as hereinafter set forth, is planned at a gross density of one unit per three acres, (unless specified means of sewage disposal and of public water supply are provided) with the recognition that, even at a density of one unit per three acres the ability to build must be considered and proved by the applicant on a lot by, lot basis.
