(a) This Chapter shall apply to the rural areas of the County outside of the Urban Services Line and the Rural Services Line (USL and RSL), and shall include all Tentative Map approvals for land divisions and all Development Permits issued pursuant to Chapter 18.10. Included in these categories are all applications to create additional parcels, additional housing units, additional visitor accommodations, or additional organized camp facilities on land designated in the General Plan as Suburban Residential, Rural Residential, Mountain Residential, Parks and Recreation, Resource Conservation, or Non-commercial Agriculture. Existing development on a parcel shall be deducted from the intensity of use allowed by this Chapter in determining the amount of additional development (if any) to be allowed on the property. (Ord. 4406, 2/27/96)
(b) This Chapter shall not prevent the development of a single residential unit on an existing legal parcel of record.
(c) This Chapter shall not require the decision-making body to approve the minimum lot sizes or maximum densities of use determined by the matrices of this Chapter if a denial or modification of the project is required by the policies of the General Plan and Local Coastal Program Land Use Plan or by other overriding concerns which are reflected in findings required by State law or County ordinances.
(d) If a Use Permit was issued and exercised prior to December 23, 1980, which allows the construction of 2 to 4 dwelling units on one parcel, and the appropriate findings for a land division can be made, the matrix system shall not be used to limit the division of that parcel into fewer lots than the number of dwelling units which were originally approved. The density of the proposed division may be deemed to comply with the General Plan by virtue of the fact that the approved Use Permit constitutes existing development. (Ord. 3594, 11/6/84)
