(Ord. 1988-242 § 3 (Exh. B)(part), 1988)

18.64.050 - Review—Guiding principles for external design.

In carrying out the purpose of this title with respect to the external design of structures, the commission shall keep in mind the following principles:

A.

It is not a purpose of this chapter that control of architectural character should be so rigidly enforced that individual initiative is stifled in the design of any particular structure, or substantial additional expense is required; rather, it is the intent of this chapter that any control exercised be the minimum necessary to achieve the overall objectives of this title.

B.

Good architectural character is based upon the suitability of a structure for its purposes; upon the appropriate use of sound materials; and upon the principles of harmony and proportion in the elements of the structure.

C.

Good architectural character is not, in itself, more expensive than poor architectural character, and is not dependent upon the particular style of architecture selected.

D.

The relationship of a structure to its surroundings is of greater importance than the quality of design of the individual structure.

E.

Nonresidential structures shall be compatible with the rural atmosphere of Portola Valley. Small, interesting shapes and groupings are preferred to large, simple, geometric forms of comparable size.

F.

When deemed warranted by the staff or the ASCC, an evaluation shall be made of the compatibility of the proposed project with existing off-site conditions and with potential future off-site conditions to the extent such conditions can reasonably be anticipated. This evaluation should demonstrate compatibility of the proposed height, bulk and mass with conditions in the area, including anticipated future development of adjoining properties, even if such compatibility requires adhering to standards that are more restrictive than the maximums set forth in this title.

(Ord. 1995-285 § 1 Exh. A (part), 1995: Ord. 1986-210 § 3, 1986: Ord. 1979-166 § 25 (part), 1979; Ord. 1967-80 § 1 (6912.7), 1967)

18.64.060 - Review—Site development criteria.

In addition to reviewing the proposed development in relation to specific requirements and conditions of this title, the architectural and site control commission shall consider such of the following as are applicable to the particular case. This may result in the necessity to reduce floor area, impervious surface or height and may require an increase in setbacks from property lines.

A.

Design of the structure so as to minimize disturbance to the natural terrain;

B.

Maximum possible preservation of existing vegetation;

C.

Design and location of the structure in relation to provision of adequate light and air to itself and its neighbors;

D.

Landscaping, screening, and fencing to preserve privacy and mitigate adverse effects on neighboring properties;

E.

Location of entrances and exits and layout of internal circulation in relation to traffic safety and ease and convenience of movement;

F.

Arrangement and intensity of night lighting in relation to public safety and effect on adjoining properties;

G.

Planting and site design as related to problems of drainage and soil erosion;

H.

Materials and colors shall be compatible with the rural setting of the town and the surrounding landscape and structures;

I.

Grading so as to minimize the apparent disturbance to the natural terrain;

J.

With respect to mobile homes certified under the National Mobile Home Construction and Safety Standards Act of 1974, building design may be reviewed only in regard to roof material and color, roof overhang and siding material and color.

18.64.070 - Dedications and improvements required.

Because the establishment or enlargement of activities and facilities will result in other changes, including an increase in vehicular and other traffic, noise, and activities associated with traffic, the following dedications and improvements are deemed to be necessary and the architectural and site control commission may recommend that they be made and installed so as to prevent congestion and the other hazards that are related to the intensified use of the land:

A.

All streets, both thoroughfares and locals, which are on the front, side or rear property lines of the subject property shall be dedicated to the full width required by the town on the side of the street or highway center line bordering the property. The improvements and dedications may include the following, and appurtenant easements: berms, stabilized shoulder, pedestrian paths, trails, street paving, street trees or other planting, street signs, street lights, and all required utilities, and shall conform to the standards established by the town.

(Ord. 1967-80 § 1 (6912.5), 1967)

18.64.080 - Request for reports or recommendations from town officials.

The architectural and site control commission may request reports and recommendations from the fire chief, town engineer, building inspector, health officer or any other officer of the town regarding matters in their fields of competence or under their jurisdiction and which would be affected by the proposed use or structure.

(Ord. 1967-80 § 1 (6912.6), 1967)

18.64.085 - Notification.

The secretary of the planning commission shall notify owners of properties which adjoin the property described in an application and any homeowners associations whose membership area encompasses the property.

Alternatively, such notification can be by telephone at least four days prior to the meeting. Failure to comply with these notification requirements shall not nullify the action of the architectural and site control commission.

(Ord. 1988-242 § 3 Exh. B (part), 1988)

18.64.090 - Action by architectural and site control commission.

The architectural and site control commission shall meet and act on such applications within fifteen days of the time such applications are submitted to the responsible official unless a longer time is agreed to by the applicant. The aforesaid commission shall determine from the reports and data submitted, whether the use and structures will meet the requirements and objectives of this title and shall, upon making a positive finding, recommend approval to the responsible official or body. If from the information submitted, the commission finds that the requirements of this title and the objectives set forth in this title would not be secured, they shall disapprove or recommend approval subject to specified conditions, changes or additions, to the official or body authorized to act on the particular class of permit.

(Ord. 1967-80 § 1 (6912.9), 1967)

18.64.095 - Effective date of action.
