Except as permitted in this chapter, at the time of the erection of any main building or structure, at the time any main building or structure is enlarged or increased in capacity, or at the time a main building or structure is put to a different use, there shall be provided and maintained in all districts, off-street parking spaces for automobiles in accordance with the schedule set forth in Section 18.60.110.

(Ord. 1967-80 § 1 (6210), 1967)

A. Required parking for dwellings. Each parking space in a garage or carport shall be at least ten feet by twenty feet. Guest parking spaces shall meet the requirements set forth in subsection B. of this section. There shall be adequate provision for ingress and egress to all parking spaces.

TABLE 4—PARKING LOT DIMENSIONS

Width of stall .....9'

Length of stall .....18'*

Width of aisle .....25'

*Up to two feet of overhang may be deducted from required stall length if the overhang does not interfere with planting, walks or other site features and is approved by the architectural and site control commission.

The foregoing standards are for ninety-degree parking and an aisle for two-way traffic. Parking at other angles shall provide for similar geometric standards as approved by the town engineer.

(Ord. 1987-223 § 1, 1987; Ord. 1979-166 § 16 (part), 1979; Ord. 1967-80 § 1 (6210.1 (A)), 1967)

Off-street parking facilities shall be located as specified in this section. Where a distance is specified, the distance shall be the walking distance measured from the nearest point of the parking facility to the nearest entrance of the building that the facility is required to serve.

A.

In residential districts, required parking facilities, except required guest parking spaces, shall be in a carport or garage and all spaces shall be located on the same parcel or building site as the buildings they are required to serve unless otherwise authorized by conditional use permit, or otherwise regulated by the opt-in housing diversification program established by the Portola Valley Housing Element. This requirement does not apply to the R-MF-23 zoning district.

B.

For uses in other districts, parking spaces may be located on separate sites provided they are not over two hundred fifty feet from the buildings they are required to serve.

C.

When the required off-street parking facilities are not situated on the same parcel as the use they are required to serve, there shall be recorded a covenant as required for joint use under paragraph D.3 of Section 18.60.070.

D.

In R-1/7.5M, 15M and 20M zoning districts, where the ASCC finds there is no reasonable location for a second required covered parking space that would have direct unobstructed vehicular access, such required parking space may be uncovered and/or in tandem, provided that in the case of an uncovered space, two hundred square feet shall be considered as floor area for purposes of determining compliance with the floor area limitations on a parcel. On parcels of twenty thousand square feet or less, an uncovered parking space may occupy required yard areas upon approval by the ASCC and after notification to affected neighbors.

(Ord. 2024-451 § 1 (Att. A), 2024; Ord. 2024-450 § 1 (Att. A), 2024; Ord. 1967-80 § 1 (6210.1 (B)), 1967; Ord. 2001-338 § 7 (part), 2001)

A. For the purpose of this section, "floor area" shall mean the gross floor area in the building other than floor space designated and used exclusively for parking and loading spaces, building service and maintenance, or storage of equipment and furnishings belonging to the occupants of the building but not in current use.

B.

When units of measurements determining number of required parking spaces result in requirement of a fractional space, any fraction up to and including one-half shall be disregarded and fractions over one-half shall require one parking space.

(Ord. 2024-451 § 1 (Att. A), 2024; Ord. 2024-450 § 1 (Att. A), 2024; Ord. 1967-80 § 1 (6210.1 (C)), 1967)

Whenever on any parcel there is a change in use, or increase in floor area, or in the number of employees or other unit of measurement specified in this chapter to indicate the number of required off-street parking spaces and such change or increase creates a need for an increase of more than ten percent in the number of off-street parking spaces, as determined by the tables in this chapter, additional off-street parking spaces shall be provided on the basis of the increased requirements of the new use, or on the basis of the total increase in floor area, or in the number of employees, or in other unit of measurement. The effects of additions, enlargements, and changes in use subsequent to July 18, 1967, shall be cumulative in regard to off-street parking requirements.

(Ord. 1967-80 § 1 (6210.1 (D)), 1967)

In the case of a use not specifically mentioned in Section 18.60.110, the requirements for off-street parking facilities for a use which is so mentioned and to which the use is similar, shall apply as determined by the planning commission. In the case of mixed uses, the total requirements for off-street parking facilities shall be the sum of the requirements for the various uses computed separately. Off-street parking facilities for one use shall not be considered as providing required parking facilities for any other use except as specified in Section 18.60.070 for joint use.

(Ord. 1967-80 § 1 (6210.1 (E)), 1967)

The planning commission may, upon application by the owner or lessee of any property, authorize the joint use of parking facilities by the following uses or activities under the conditions specified in this section:

A.

Up to fifty percent of the parking facilities required by this section for a use considered to be primarily a daytime use may be provided by the parking facilities of a church or any auditorium incidental to a public or parochial school or of a use considered to be primarily a nighttime use; up to fifty percent of the parking facilities required by this section for a use considered to be primarily a nighttime use may be provided by the parking facilities of a use considered to be primarily a daytime use, provided such reciprocal parking area shall be subject to conditions set forth in subsection D of this section.

B.

Up to one hundred percent of the parking facilities required by this section for a church or for an auditorium incidental to a public or parochial school may be supplied by parking facilities of a use considered to be primarily a daytime use, provided such reciprocal parking area shall be subject to conditions set forth in subsection D of this section.

C.

The following uses are typical daytime uses: banks, business offices, retail stores, personal service shops, clothing or shoe repair or service shops, and similar uses. The following uses are typical of nighttime uses: bars, and auditoriums other than those incidental to a public or parochial school or churches.

D.

Conditions required for joint use shall be as follows:

1.

The structure or use for which application is being made for authority to utilize the existing off-street parking facilities provided by another structure or use shall be located within two hundred fifty feet of such parking facility.

2.

The applicant shall show that there is no substantial conflict in the principal operating hours of the building or uses for which the joint use of off-street parking facilities is proposed.

3.

If the building, structure, or improvement requiring parking space is in one ownership and the required parking space provided in another ownership, partially or wholly, there shall be a recording in the office of the county recorder, of a covenant by such owner or owners for the benefit of the town in the form first approved by said town that such owner or owners will continue to maintain such parking space so long as the building, structure, or improvement is maintained within the town. The covenant required in this paragraph shall stipulate that the title to and right to use the parcel or parcels upon which the parking space is to be provided will be subservient to the title to the premises upon which the building is to be erected, and that it is warranted that the parcel or parcels are not and will not be made subject to any other covenant or contract for use without prior written consent of the town.

(Ord. 1967-80 § 1 (6210.1 (F)), 1967)

Common parking facilities may be provided in lieu of the individual requirements contained in this chapter, but such facilities shall be approved by the planning commission as to size, shape, and relationship to sites to be served, provided the total of such off-street parking spaces, when used together, shall not be less than the sum of the various uses computed separately, taking into consideration allowable reductions for joint use as set forth in Section 18.60.070. When any such common facility is to occupy a site of five thousand square feet or more, then the parking requirements as specified in this chapter for each of two or more participating buildings or uses may be reduced not more than fifteen percent upon approval of development plans by the planning commission in the manner prescribed for a conditional use permit as set forth in Chapter 18.72, provided such area saved be preserved as open space in addition to other open spaces required by this title. In any case, where common parking facilities are to be provided, there shall be a covenant recorded in a form first approved by the town covering the matters set forth under paragraph D (3) of Section 18.60.070.

(Ord. 1979-166 § 16 (part), 1979: Ord. 1967-80 § 1 (6210.1 (G)), 1967)

The plan of the proposed parking area shall be submitted to the building inspector at the time of the application for the building permit for the structure to which the parking area is accessory. The plans shall clearly indicate the proposed development, including location, size, shape, design, curb, cuts, lighting, landscaping, and other features and appurtenances of the proposed parking lot. All plans shall be reviewed by the town planner prior to approval.

(Ord. 1967-80 § 1 (6210.1 (H)), 1967)

A. Nothing in this title shall be construed as requiring the provision of additional parking spaces for any structure legally existing August 17, 1967, except as provided in Section 18.60.050 or as may be required in the authorization of any conditional use permit or variance.

B.

The provisions of this title which require the provision of off-street parking spaces in connection with the use of property for commercial purposes may be reduced or eliminated by resolution of the council for any parcel of property which is located within any parking district hereafter formed and existing under the provisions of any parking district act approved by the council.

(Ord. 1967-80 § 1 (6210.2), 1967)

Except as otherwise provided in this chapter, the minimum number of off-street parking spaces required shall be as set forth in Table 5. More parking spaces may be required as a condition of any conditional use permit when the planning commission finds that the characteristics of the particular use require more parking. For uses not listed, the number of spaces required shall be stipulated by the planning commission.

TABLE 5

When demonstrated to the satisfaction of the planning commission that not all required parking spaces will be needed for a conditionally permitted use during initial phases of a development, the commission may permit temporary landscaping of such extra spaces provided:

1.

The applicant will be bound to develop such spaces for parking when deemed necessary by the planning commission; and,

2.

That such spaces shall not be counted as satisfying required open space or landscaping provisions of this title.

(Ord. 2024-451 § 1 (Att. A), 2024; Ord. 2024-450 § 1 (Att. A), 2024; Ord. 1979-166 § 16 (part), 1979; Ord. 1976-149 § 1, 1976: Ord. 1967-80 § 1 (6210.5), 1967)
