In the R-A zone every lot shall have a minimum lot width as follows:
B.
The official or decision-making body with the authority to otherwise approve the subdivision may approve panhandle or flag-shaped lots where the lot width and yards shall be measured in accord with this section if the following circumstances are found to exist:
1.
The property cannot be served adequately with a public street without panhandle lots due to unfavorable conditions resulting from unusual topography, surrounding land development, or lot configuration; and

Subdivision with panhandle lots will not preclude or adversely affect the ability to provide full public street access to other properties within the same block of the subject property.
C.
In approving a panhandle lot a determination shall be made as to what portion of such lot shall be the buildable lot; for purposes of this chapter, the buildable portion shall be the entire lot exclusive of any portion of the lot less than thirty-five feet in width that is used for access to the lot.

Any panhandle lot approved pursuant to this section shall meet the following requirements:
1.
The area of the buildable portion of the lot shall be a minimum ten thousand square feet or the minimum required by the zone, whichever is greater. In zone districts permitting less than ten thousand square-foot lots, the buildable portion of the lot may be less than ten thousand square feet provided the official or decision-making body with the authority to otherwise approve the subdivision finds from evidence submitted on a site plan that all requirements of this section will be met; however, in no case shall the buildable portion of the lot be less than eight thousand square feet in area. If a site plan for a subdivision with panhandle lots, with a buildable portion of less than ten thousand square feet, is approved, development within such subdivision shall conform to the plan as approved;

The minimum width for such access portion shall be twenty feet except where the access portion is adjacent to the same portion of another such lot, in which case the required minimum frontage shall be fifteen feet, provided a joint easement, ensuring common access to both such portions, is recorded;
5.
An improved driveway shall be provided within the access portion of the lot from the public street or public easement to the parking area on the buildable lot at least fourteen feet wide for single lots and twenty feet wide when serving more than one lot. The minimum overhead clearance shall be ten feet. The driveway shall be constructed to accommodate public service vehicles with a minimum of two-inch thick asphalt concrete paving on proper base with rolled edges;
6.
Drainage from the lot shall be channeled down the private access to a public street or special drainage means must be provided to the satisfaction of the City Engineer;
7.
Each lot shall have three nontandem parking spaces with an approach not less than twenty-four feet in length with proper turnaround space to permit complete turnaround for forward access to the street. This parking and access arrangement shall be designed to the satisfaction of the City Engineer;
8.
Structures permitted in the access portion of the lot shall be limited to mailboxes, fences, trash enclosures, landscape containers and nameplates. Except for mailboxes, these structures shall not be greater than forty-two inches in height if located within twenty feet of the street property line or greater than six feet in height beyond this point;
9.
The property owner of such a lot shall agree to hold the city or any other public service agency harmless from liability for any damage to the driveway when being used to perform a public service;
10.
Any other condition the official or decision-making body with the authority to otherwise approve the subdivision may determine to be necessary to properly develop such property.

§ 21.08.100 Development standards.
A.
No one-family dwelling unit, whether it be conventionally built, modular or a mobile home, shall be located on a lot in this zone unless such dwelling unit complies with the following development standards:
1.
Garage(s), which are provided to meet the parking requirements for dwellings pursuant to Section 21.44.020 of this title, shall be architecturally integrated with and have an exterior similar to the dwelling unit.
2.
All dwelling units shall have a permanent foundation. For mobile homes a foundation system installed pursuant to Section 18551 of the State Health and Safety Code shall satisfy the requirements of this section.
3.
Exterior siding material shall be stucco, masonry, wood or brick unless an alternative exterior material is approved by the City Planner. The City Planner may approve a siding material other than those listed in this section only if he or she finds that use of such materials is in harmony with other dwelling units in the neighborhood.
4.
All roofs shall have a pitch of at least three inches in twenty inches unless another pitch is approved by the City Planner. No roof shall be made of corrugated, extruded or stamped metal.
5.
