   A.   These standards shall be followed in all subdivisions regulated by this title. In addition to these standards, all subdivisions shall meet the design standards of the applicable zoning district.
   B.   Any proposed subdivision in areas of the county where topographical slopes are greater than fifteen percent (15%) or where adverse conditions associated with slope stability, erosion, or sedimentation are present, as determined by the county engineer, shall conform with the additional hillside regulations set forth in this title.
   C.   Adequate means for eliminating unsuitable conditions must be approved by the county engineer in order to develop property that has been designated in the applicable comprehensive plan, in the natural features analysis, or elsewhere, as being unsuitable for development because of flood threat, poorly drained areas, high groundwater, steep slopes, rock formation, buried pipelines, or other similar conditions likely to be encountered.
   D.   The limits of the subdivision shall encompass the full extent of the owner's lot or "contiguous parcels", as herein defined.
   E.   The decision making body may require modifications where, in its opinion, site planning has not sufficiently addressed the existing natural features. (Ord. 389, 6-14-2000; amd. Ord. 768, 1-12-2011)
8-6A-2: BLOCKS:
   A.   The length, widths, and shapes of blocks shall be determined with due regard to:
      1.   Provision of adequate building sites suitable to the special needs of the type of use contemplated including the base district requirements as to property sizes and dimensions.
      2.   Avoiding double front lots. If unavoidable, one of the frontages shall be restricted from access.
      3.   Needs for convenient access, circulation, control, and safety of street traffic. The number of intersecting streets with arterials of all classes shall be held to a minimum.
      4.   The limitations and opportunities of topography.
   B.   Residential block lengths should be between four hundred feet (400') and six hundred feet (600').

Corner lots in residential zoning districts shall be increased five percent (5%) above the minimum property size of the applicable base district to permit appropriate front and street side setbacks.
   C.   For a distance of fifty feet (50'), side property lines originating at the front of the lot shall be within twenty degrees (20°) of right angles or radial to the street providing access.
   D.   Through lots shall be avoided except to separate developments from arterial streets or to overcome topographic restrictions.

The arrangement, character, extent, and location of all streets shall conform to the comprehensive plan or portions thereof, and shall be considered in their relation to existing and planned streets, topographic conditions, and in their appropriate relation to the proposed uses of the property to be served by such streets. All required public street improvements and additional design standards are subject to the jurisdiction of the Ada County highway district.
