The residential suburban zoning district is established to provide small (one acre or less) residential estates on municipal sewage treatment facilities and/or water systems, or larger lot development where sewer effluent and water systems can be provided. The RS district is located on the boundaries of the county's cities where municipal services are expected to be extended, and usually within a city's area of impact.

(Ord. 1998-1 § 331)

The residential suburban designation is to be applied to existing smaller lot neighborhoods which are currently developed for residential use and are designated to remain so by the comprehensive plan, and for areas of undeveloped land which are deemed suitable and appropriate for development of residential uses according to criteria set forth in the comprehensive plan. Factors to be considered in designating land for residential suburban districts should include, but not be limited to, availability of county services and roads, surrounding land uses, the suitability of the land for extension of municipal services.

(Ord. 1998-1 § 332)

(Ord. 1998-1 § 335)

The following methods of subdividing are permitted in the RS zone:

A.

Open space designed subdivision (Section 16.28.010 of subdivision ordinance, Title 16 of this code) with density of one dwelling per acre.

B.

Conventional Subdivision.

1.

Within a city's area of impact, a minimum lot size of five acres is required where septic tank and drainfield sewage disposal systems are proposed. Such lots may not be further subdivided, and the plat and deeds must so indicate. Lots of less than five acres must employ municipal treatment of sewage or private sewage treatment systems which treat sewage such that the effluent is equal to or less contaminated than that of the City of Pocatello sewage treatment facility. Such treatment facilities shall be built to the design standards of the city whose impact area it is within.

2.

Outside a city's area of impact, the usual lot size of one acre may be proposed for on-site sewage disposal where soil type, distance to ground water and other factors are adequate to prevent ground or surface water contamination.

C.

Planned unit development provided that municipal water and sewer is provided and limited to locations within area of city impact (ACI); density may be up to one dwelling per one-third acre; for residential uses or for mixed-use developments which include neighborhood commercial uses subordinate to residential uses in the same development.

1.

Developments for uses other than residential and neighborhood commercial shall not be permitted in the RS district.

2.

The increased density allowed in a PUD shall be offset by provision of common open space equal to at least ten percent of the net developed area of the project. The open space shall be usable ground.

3.

Minimum size for a planned unit development in the RS district shall be ten acres and the maximum size is one hundred (100) lots or dwelling units and one hundred (100) acres.

D.

All subdivisions on a city boundary must be annexed into that city which has designated that land to be within its area of city impact; in the event the city declines, in writing, to annex the development, the county shall hear the application in accordance with its area of impact agreement with the city, or Idaho Code shall apply if none exists.
