ENVIRONMENTAL DETERMINATION:

This proposal is categorically exempt from the provisions of the California Environmental Quality Act (CEQA) as specified in Section 15303(e).

PROPOSAL:

The applicant has submitted a request for a new single-family dwelling on a property located at 4795 Paradise Drive. The property is currently developed with a single-family dwelling, which is proposed to be demolished. The property slopes steeply from Paradise Drive, but the proposed building area is very flat. The proposed home is a two level design in a "U" shape, forming a courtyard in the middle. There is an existing swimming pool that would remain between the road and the proposed structure.

The ground level of the new home would be comprised of the family room, kitchen, living room, dining room, one bedroom/bathroom, laundry room, and a three-car garage. The upper level would be located above the rear half of the ground floor, and the large retaining wall would be integrated into the wall of the new structure. The upper level would consist of the master bedroom and bathroom, two additional bedrooms, and two bathrooms.

The proposed structure would cover approximately 2,950 square feet (15 % lot coverage), which is the maximum allowable lot coverage for the zoning district. The floor area of the proposed home is 3,800 square feet, which meets the floor area limits for the property. The proposed home would encroach on the side-yard setback on the north (right) by approximately six feet; therefore a variance is requested for reduced side-yard setback.

The proposed materials for the home would be stucco siding with a tile mansard roof. A color and materials board will be available at the Design Review Board meeting.

ANALYSIS:

Zoning

As previously stated, the applicant is requesting a variance for reduced side-yard setback (9 feet in lieu of the required 15 foot setback). The project appears to be in conformance with the remaining development regulations of the RO-1 zoning district.

Design Issues

The existing ranch style home is built with stucco siding and a typical pitched roof with wood shingles. The architectural style of the new home would be significantly different. There would be large arched windows on the interior of the "U" shape, and the roof would be a mansard style roof. The upper level element would increase the structure’s appearance of size and bulk.

The most affected properties would be on the left and right sides of the of the subject property. The properties across Paradise Drive are significantly downhill from, and out of view of, most of the proposed structure. Although the appearance of size and bulk would increase, there are no apparent view blockage issues caused by the proposed structure.

The applicant has submitted a minimal landscaping plan with the application. Most of the lot is currently un-landscaped, and there appears to be much opportunity to increase the amount of landscaping on the property. Between the stepped retaining walls in the rear of the property, and below the swimming pool near the front of the property are two distinct locations where additional landscaping could be incorporated. It is recommended that the Design Review Board review the possibility of adding more landscaping to the property (see condition #7).

Variance

In order to grant the requested variance, the Board must make the following findings as required by Section 4.03.05 of the Tiburon Zoning Ordinance:

1. Because of special circumstances applicable to the property, including size, shape, topography, location, or surroundings, the strict application of this Ordinance will deprive the applicant of privileges enjoyed by other properties in the vicinity and in the same or similar zones.

The applicant has indicated that he would like to make use of the elements of the existing structure as much as possible when building the new home to help limit the impact of the project on the adjacent neighbors. However, upon review of the submitted plans, it is apparent that the project would call for the demolition of more than 50 percent of the existing structure, which requires the project to be reviewed as new construction. The portion of the building that is currently within the side-yard setback is not proposed to be demolished. Since the project as a whole is considered new construction, the existing non-conformity is a special circumstance to the property that reduces the applicant’s ability to construct a home that meets all aspects of the zoning ordinance.

2. The variance will not constitute a grant of special privileges, inconsistent with the limitation upon other properties in the vicinity and in the same or similar zones.

The applicant has suggested that the granting the variance would not constitute a special privilege because the placement of the new home would be consistent with the existing conditions and relationships of other properties in the vicinity.

3. The strict application of this Ordinance would result in practical difficulty or unnecessary hardship.

The applicant has suggested that it would be an unnecessary hardship to be required to reconfigure the existing foundation more than necessary in order to resolve an existing non-conforming issue on the property.

4. The granting of the variance will not be detrimental to the public welfare or injurious to other properties in the vicinity.

The new home would not be increasing the non-conformity of the existing structure. It can be concluded that since the existing home has not resulted in significant privacy or other impacts detrimental to the public welfare or injurious to other properties in the vicinity, than neither will the new structure.

Public Comment

A letter has been submitted by Hayden and Donna Ames, 4785 Paradise drive, received 9/12/02. The letter states that there are no significant design concerns, although additional support for the variance should be given by the applicant. Mr. and Mrs. Ames also want to ensure that the appropriate measures for under-grounding utilities be taken by the Town.

RECOMMENDATION:

It is recommended that the Board review this project with respect to Zoning Ordinance Sections 4.02.07 and 4.03.05 (Guiding Principles and Variance Findings by Acting Body). If the Board finds that the design of the project is consistent with the Guiding Principles for Site Plan and Architectural Review, and all necessary findings can be made for the variance for reduced side-yard setback, then it is recommended that the project be approved with the attached Conditions of Approval.
