§ 23.04.026. Residential Rural Category.
The minimum parcel size for new lots in the Residential Rural category is based upon site features including: Remoteness, fire hazard, fire response time, access and slope. Minimum parcel size is determined by applying the following tests to the site features as described in subsections a through d of this section. The allowable minimum size is the largest area obtained from any of the tests, except as provided for cluster divisions by Section 23.04.036.
a.
Remoteness test: The minimum parcel size is to be based upon the distance of the parcel proposed for division from the nearest urban or village reserve line, measured on the shortest public road route between the reserve line and the site. Private roads are to be included in the measurement only when they provide the only access to the site from a public road. When a lot proposed for division is within the distances given from more than one reserve line, the smallest parcel size is to be used as the result of this test.

Fire hazard/response time test. The minimum parcel size is to be based on the degree of fire hazard in the site vicinity, and the response time. Response time is the time necessary for fire protection agency to receive the call, prepare personnel and fire equipment for response, dispatch appropriate equipment, and deliver the equipment and personnel to each proposed parcel from the nearest non-seasonal fire station. Fire hazard is defined by the Safety Element of the general plan; response time is determined by the fire protection agency having jurisdiction.

More than 15 Minutes 10 acres

c.
Access test:
(1)
General access test rules. The minimum parcel size is based upon the type of road access to the parcel proposed for division, provided that the proposed parcels will use the road considered in this test for access, either by way of individual or common driveways. Where access to a parcel is over roadways with differing quality of improvement, the minimum size is as required for the road with the least improvement.
(2)
Timing of improvements and right-of-way availability. If the improvements do not exist at the time of the subdivision application, the conditions of approval for the tentative map shall require the construction of access improvements which meet the minimum requirements specified by this section. Additional right-of-way width may be required to allow for the construction of required improvements. The right-of-way required by the table in subsection c(4) of this section shall exist as either: (1) an offer to dedicate to the public or (2) as a private easement prior to acceptance of the tentative map application for processing. If the access is a private easement, it may be required to be offered for dedication to the public as a condition of approval of the tentative map.
(3)
Conditions of approval for improvements and maintenance. In the event that a land division application is approved, the extent of on-site and off-site road improvements required as a condition of approval, and acceptance of the new road for maintenance by the county may vary. This will depend on the parcel size proposed and the requirements of county standards and specifications in effect at the time the tentative map is approved. Paved roads will be required when:
(i)
Parcels of less than 5 acres are proposed; the access road is identified as a collector or arterial by the Circulation or Land Use Element; or
(ii)
The road will have the potential to serve 20 or more lots or the road will have the potential to experience a traffic volume of 100 or more average daily trips (ADT), based on the capability for future land divisions and development in the site vicinity as determined by the Land Use Element. In the event it is determined by staff that a road will serve 20 or more lots, or will experience 100 ADT or more, the basis for such a determination shall be explained in the staff report on the subdivision.
(4)
Parcel size criteria. Minimum parcel size based on the access test shall be determined as shown in the following table (an existing road which is improved to higher standards than those specified in the table will also satisfy the following criteria).

Notes:
1.
A County Standard Gravel Road is a road that satisfies or has been constructed to meet the specifications for a gravel road set forth in the county's "Standard Specifications and Drawings." Public maintenance means that the road is maintained by the state, county, or special district.
2.
Organized maintenance is by an organized group of property owners through an association which collects fees and contracts for repairs.
d.
Slope test: Site slope shall be measured as defined in Chapter 23.11 (Definitions - Slope).
