  • 25.1 Purpose: Provide basic access and fire protection for older subdivided lands, and insure geological stability by the establishment of regulations setting minimum public health and safety standards and procedures for implementation and reimbursement. The implementation of this Ordinance will help insure the continued development of these substandard older subdivisions in a manner that will not result in increased health and safety hazards to persons and property from fire, traffic accidents, landslides and other earth movements. Improved access will help emergency responses by public safety agencies such as police, fire and ambulance services. Within the “SOS” combining district, all uses of land shall comply with the regulations of the base zoning district and with the additional regulations of the “SOS” combining district.

  • 25.2 Applicability: This district shall be applied to predominantly undeveloped older subdivided properties of urban or suburban densities, known as “paper subdivisions”, which are substandard in relationship to existing zoning and subdivision regulations with design, size, or physical improvements not meeting County standards. Such lots should be characterized by steep slopes and lack of adequate public services and facilities such as streets, fire, sewer or water services.

  • 25.3 Uses permitted: All uses permitted by the base zoning district, subject to the regulations of this Article and performance standards of Section 25.10.

  • 25.4 Uses permitted subject to first obtaining a Minor Use Permit in each case:

    • (a) Uses permitted in Section 25.3 when not in compliance with the performance standards of Section 25.10, as provided for in Section 41.3(a).

    • (b) Any development on or off-site, within the “SOS” district, when existing off-site improvements are not in compliance with the performance standards of Section 25.10. For the purposes of this Section, “improvements” include, but are not limited to, public streets, fire facilities and public water or sewer systems; “onsite” shall mean any development on a lot of record, and “off-site” shall mean all other areas within the “SOS” district.

    • (c) This section shall not apply to individual connections of dwellings or structures to pre-existing sewer lateral or water distribution lines, to reconstruction, replacement, additions or alterations to residences or residential uses existing prior to the effective date of being zoned “SOS”; or to uses authorized by any use permit granted pursuant to this Section or Section 25.5.

  • 25.5 Uses permitted subject to first obtaining a Major Use Permit in each case: Uses permitted in Sections 25.3 and 25.4 when not in compliance with the performance standards of Section 25.10 as provided for in Section 41.3(a).
