Sec. 26C-50A. - Purpose.

To implement the provisions of the resources and rural development land use category (Section 2.8.1) of the general plan, namely to provide protection of lands needed for commercial timber production, geothermal production, aggregate resources production; lands needed for protection of watershed, fish and wildlife habitat, biotic resources, and for agricultural production activities that are not subject to all of the policies contained in the agricultural resources element of the general plan.

Sec. 26C-52. - Permitted residential density and development criteria.

The use of land and structures within this district is subject to this article, the general regulations of this ordinance, and the provisions of any district which is combined herewith. Policies and criteria of the general plan and coastal plan shall supersede the standards herein. Development shall comply with coastal plan policies.

(a)
Density: Residential density shall be between twenty (20) and three hundred twenty (320) acres per dwelling unit as shown in the general plan land use element or permitted by a B combining district, whichever is more restrictive, provided that no more than four residential units shall be approved per parcel.
(b)
Minimum lot size shall be six hundred forty (640) acres, unless a different area is permitted by a B combining district.
(c)
Minimum lot width: The minimum average lot width within each lot is one hundred twenty-five feet (125′).
(d)
Height limits: Height for all structures is measured as the vertical distance from the average level of the highest and lowest point of that portion of the lot covered by the building to the topmost point of the roof.

An increase in height for structures east of Highway 1 up to a maximum of thirty-five feet (35′) may be considered if the appropriate review body finds that the structure is no higher than twenty-four feet (24′) feet above the corridor route grade directly across from the building site, will not block coast views from the corridor route or neighboring properties and is compatible with community character.

Where these requirements conflict with the height, site, and bulk criteria in Appendix B (Bane Bill) of the coastal plan, for those properties listed, the requirements of Appendix B shall be followed.

Expansions of such structures which do not comply with the revised height restrictions shall comply with the new definition of height measurement as stated above, except that the expansion, up to ten percent (10%) of floor area and not to exceed four hundred (400) square feet, shall be allowed, provided that the height does not exceed the height of the structure prior to the expansion, or the building height allowed by this chapter, whichever is greater.

(1)
West of Highway 1: Residential height limits are sixteen feet (16′). Commercial height limits are twenty-four feet (24′).
(2)
Bodega Bay Core Area residential: Sixteen foot (16′) height limit except that in major developments up to fifteen percent (15%) of the units may exceed the height limit.
(3)
East of Highway 1 in the Sereno Del Mar Subdivision: Residential height limits are sixteen feet (16′). The Sereno Del Mar Architectural Review Committee may grant a higher structure to a maximum of twenty-four (24′) feet in accordance with subsection (7) below.
(4)
East of Highway 1 and visible from designated scenic roads: Residential and commercial height limits are twenty-four feet (24′).
(5)
East of Highway 1 and are not visible from designated scenic roads: Fifty feet (50′).
(6)
Agricultural structures: Fifty feet (50′); however, structures shall not obstruct views of the shoreline from coastal roads, vista points, recreation areas, and beaches; and structures shall be sited to minimize visual impacts.
(7)
Maximum height for telecommunication facilities is subject to the provisions of this article and Section 26C-325.7.
(8)
An increase in height for residential structures west of Highway 1, up to a maximum of twenty-four feet (24′) feet, may be approved if the appropriate review body finds that the structure is no higher than sixteen feet (16′) above the corridor route grade directly across from the building site, will not block coast views from the corridor route or neighboring properties and is compatible with community character.
(9)
A legal single family dwelling or appurtenant structures for which a building permit was issued after December 1, 1980, shall be considered to be conforming with regard to the height measurement. Repair, and remodeling of such structures shall be allowed provided that the height does not exceed the height of the structure prior to the remodel or repair, or the building height allowed by this chapter, whichever is greater.

However, in no case shall the front yards be reduced to less than ten feet (10′). Further the director of the permit and resource management department may require a use permit if the reduction might result in a traffic hazard.
(6)
Cornices, eaves, canopies, bay windows, fireplaces, other cantilevered portions of structures, and similar architectural features may extend two feet (2′) into any required yard.

(2)
All development shall be subject to site development and erosion control standards. These standards are to be used as the minimum standards for development in the coastal zone. Where both these standards and the policies of the coastal plan apply to a development, the policies of the coastal plan shall take precedence over these standards. Where the policies and standards of the general plan are more restrictive than those of the coastal plan or any of the standards below, the general plan standards and policies shall apply.

Each permit must conform to Chapter V access provisions of the coastal plan. An offer of dedication is required if an access way is shown on the property in the access plan. Consult Chapter V in the coastal plan for a description of each access way and procedural requirements for dedication. In addition, existing prescriptive rights must be protected even if no access way is shown in the access plan.

Two types of access may be required: Lateral and/or vertical.
a.
Lateral access refers to access paralleling the water's edge, either on the beach or the bluff. For all new development between the first public road and the ocean, granting of lateral easements to allow for public access along the shoreline shall be mandatory, unless the project has no direct or cumulative impact on the availability of public access to the coast. When there is a bluff, beach access to the toe of the bluff should be dedicated. If not, a twenty-five feet (25′) wide access way should be dedicated. If a bluff top trail is shown in the access plan, a bluff top easement dedication shall be required to be described as an area beginning at the bluff edge extending approximately twenty-five feet (25′) inland. In no case shall the dedicated easement be required to be closer than ten feet (10′) to a residential structure.
b.
Vertical access dedications are necessary to provide access from the public roadway to the shoreline. A corridor easement should be a minimum of fifteen feet (15′) in width with slope easements plus the additional area necessary for the placements of improvements.
