All lots shown on the subdivision plat must conform to the minimum standards for lots in the district in which the subdivision is planned. The city will generally not approve single-family residential lots larger than one-half (1/2) acre (21,780 square feet). In the event a single-family residential lot greater than one-half (1/2) acre is platted, irrigation shall be restricted to not more than one-half (1/2) acre, pursuant to Idaho Code section 42-111, and such restriction shall be included as a plat note. District regulations are found in the zoning ordinance.
A. If lots are more than double the minimum size required for the zoning district, the developer may be required to arrange lots in anticipation of future resubdivision and provide for future streets where necessary to serve potential lots, unless the plat restricts further subdivision.
B. Double frontage lots shall be prohibited except where unusual topography, a more integrated street plan, or other conditions make it undesirable to meet this requirement. Double frontage lots are those created by either public or private streets, but not by driveways or alleys. Subdivisions providing a platted parcel of twenty five feet (25') or more between any street right of way and any single row of lots shall not be considered to have platted double frontage lots. The twenty five foot (25') wide parcel provided must be landscaped to provide a buffer between the street and the lot(s).
C. No unbuildable lots shall be platted. Platted areas that are not buildable shall be noted as such and designated as "parcels" on the plat. Green space shall be clearly designated as such on the plat.
D. A single flag lot may be permitted at the sole discretion of the hearing examiner or commission and council, in which the "flagpole" projection is serving as a driveway as provided herein, providing connection to and frontage on a public or a private street. Once established, a flag lot may not be further subdivided, but a lot line adjustment of a flag lot is not considered a further subdivision. The "flagpole" portion of the lot shall be included in lot area, but shall not be considered in determining minimum lot width. The "flagpole" shall be of adequate width to accommodate a driveway as required by this title, fire and other applicable codes. Flag lots within the townsite overlay district are not allowed, except where parcels do not have street access, such as parcels adjacent to the ITD right of way.
E. All lots shall have frontage on a public or private street. No frontage width shall be less than the required width of a driveway as provided under subsection 16.04.020M2 of this chapter and subsection D of this section. Townhouse sublots are excluded from this requirement; provided, however, that townhouse developments shall have frontage on a street.
F. In the townsite overlay district, original townsite lots shall be subdivided such that the new platted lots are oriented the same as the original lots, i.e., lots shall be subdivided in such a way as to maintain frontage on both the street and alley. Exceptions may be made for corner properties with historic structures. (Ord. 1191, 2015)
