(A) All subdivisions shall result in the creation of lots which are developable and capable of being built upon. A subdivision shall not create lots which would make improvement unfeasible due to size, shape, steepness of terrain, location of watercourses, problems of sewerage, driveway grades or other physical conditions.
(B) Where required by this chapter, all lots or parcels created by the subdivision shall have frontage on a street, improved to standards hereinafter required, equal to at least the street’s minimum required width from top back of curb on one side of the street to the back of sidewalk on the abutting side. Lots and parcels created by the subdivision with frontage along a previously established public street shall only be required to install a half street as defined in § 155.008 of this code. This frontage standard shall not apply to commercial subdivision lots where adequate executed cross-access agreements are provided between any and all affected developments and/or properties. Land designated as public right-of-way shall be separate and distinct from lots adjoining such right-of-way and not be included in the area of such lots.
(C) Flag lots are not allowed in subdivisions.
(D) The minimum area and dimensions of all lots shall conform to the requirements of this code for the zoning district in which the subdivision is located.
(E) The interior side lot lines of all lots shall be within 30 degrees of perpendicular to the street which the lot faces, or within 30 degrees of perpendicular to the center of curves, if such street is curved. Side lines of lots shall be within 30 degrees of perpendicular to the center of a cul-de-sac on which the lot faces. All interior side lot lines shall extend at the minimum of 30 degrees perpendicular, a minimum distance of 50 feet.
(F) Corner lots for residential use shall be platted ten feet wider than interior lots in order to facilitate conformance with the required street setback requirements of this code.
(G) A lot shall not be divided by a city limit line or county boundary line.
(H) Remnants of property shall not be left in the subdivision which do not conform to lot requirements or are not required or suitable for common open space, private utility or public purpose.
(I) Double frontage lots are not permitted unless approved by the County Commission after receiving a recommendation from county staff and the Planning Commission. The street frontage adjacent to the rear of any approved double frontage lots shall be improved by the subdivider in accordance with the standards set forth in the county’s subdivision standards. Unless specifically approved by the county, no double frontage lot shall have vehicular access from the street frontage adjacent to the rear of the lot.
(J) All portions of all parcels from which a subdivision is created shall be included within the mapped boundary description of the subdivision plat, unless a portion of land qualifies for, and is approved as, an agricultural land or other approved exemption from platting requirements, pursuant to § 155.393 of this code and applicable state law.
(K) Building envelopes shall be required to be shown on all final plats designating the buildable area on each lot. Building envelopes shall take into account minimum setback requirements, utility and access easements, physical constraints such as steep or unbuildable slopes, waterways, wetlands, faults, geologic hazards, water source protection areas and any other features necessary and which are in accordance with this chapter. The accurate identification of the building envelope in the field is the responsibility of the developer. A certificate of survey, prepared by a state-licensed professional land surveyor, may be required by the county. Building envelopes for single-family dwellings shall not be less than 5,000 square feet of contiguous area.
(L) Areas of lots which are 25% slope or greater are considered unbuildable and shall not be included within the building envelope. Lots which contain a building envelope with slopes greater than 15%, but less than 25% shall submit a geotechnical investigation and slope stability analysis, along with a site plan with the preliminary plat application, which has been prepared by a state-licensed professional engineer. The site plan shall include the driveway location, driveway grade, existing and proposed contour lines, location of and engineering design for all retaining walls in excess of four feet, a grading and drainage plan (including slope stability analysis) for all cut and fill areas and the finished floor elevation of the home. Slope stability analyses shall demonstrate that the proposed structure is stable on the slope to a minimum factor of safety of one and one-half under static conditions and one and one-tenth under pseudostatic conditions in conformance with the provisions in §§ 155.220 through 155.237 of this code (geologic hazards). The County Engineer shall review the analysis and site plan and may require peer review of any submitted engineering report by the County Geologist or other state-licensed professional engineer. The Building Official may require the developer to provide special inspections and written verification from a state-licensed professional engineer regarding construction compliance with the engineered site plan and recommendations of the geotechnical report.
(M) Shape of lots: lot lines shall generally be perpendicular with the street and run radically away from the street.
