103-2.05 Limited Exceptions

  1. Where multi-family residential, commercial, or industrial development is proposed in conjunction with a subdivision which would otherwise qualify for a type other than Type "A,” limited exceptions may be approved by the Director with respect to Type "A" subdivision street improvement requirements, including but not limited to industrial or commercial street cross-section (Plate R-13).
  2. Where commercial or industrial development is proposed in conjunction with a Type "A" subdivision which also includes residential development, limited exceptions may be approved by the Director with respect to street improvements shown on industrial or commercial street cross-section (Plate R-13) and alleys.

Sec. 103-3 Private Streets

The use of private streets within a subdivision requires a Development Variation as specified by the Land Division Ordinance. When private streets are approved for use, an acceptable entity shall be formed for street and drainage maintenance prior to recording. 

The following notes shall be placed on the street improvement plans before the Director signs them:

  1. The Subdivider's engineer shall be responsible for inspection of all improvements outside of County road right-of-ways and certify such to the County. No changes shall be made to these plans without the approval of the Director.
  2. Subdivider shall obtain the necessary building, grading, and encroachment permits prior to starting any work required by these plans.

Sec. 103-4 Pedestrian Accessibility Guidelines

Federal and state regulations require that each facility or part thereof shall be designed 11 and constructed in such a manner that the facility is readily accessible to and usable by individuals with disabilities.

Every project, including encroachment permit projects, within the R/W that proposes to construct sidewalk/pedestrian walkway must be designed in compliance with the accessibility requirements of ADA, ADAAG, and Title 24 requirements. If it is found that an accessibility design standard can not be fully incorporated in a design, an accessibility design exception will be required, subject to the Director’s approval. For an exception to be approved, it will be necessary to document that it is technically infeasible to do so because existing physical structural conditions or because other existing physical or site constraints prohibit modification or when a unique characteristic of terrain prevents the incorporation of the accessibility standard.
