18.60.070 Joint use.
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)
18.60.080 Common facilities.
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.

RE: SFO Roundtable Report/Increased Perception of Air Traffic Noise I followed up with our contact at the SFO Roundtable to check on the possible bases for Portola Valley residents’ reports of increased air traffic noise.
My contact reported two possible bases for increased air traffic noise in Portola Valley: Possible changes in noise from local airports (San Carlos, Palo Alto), which is outside the purview of the SFO Roundtable, and repairs being made to one arrival runway for SFO.
1. I have received information to enable me to reach out to local airports regarding Portola Valley noise complaints. I will follow up with the contacts to ask whether there are any changes to traffic patterns or other bases for smaller planes flying over Portola Valley. Note that training sessions out of local airports may be flying over to the coast in good weather, selecting paths closer to Portola Valley and generating increased noise given the altitude at which they fly. A local airport noise report will be published in late June, which should provide useful data.
2. SFO has shut down one arrival runway for maintenance. It will reopen in July and the work appears to be on schedule. However, given the inability to use the runway temporarily, traffic issues have increased, particularly in bad weather. Air traffic controllers must “vector off” incoming flights to circle while spacing between flights that are landing is managed. The closure of the runway, in addition to the rainy weather we had last year, seems to have caused more flights to re-route to the hills and over our town, particularly flights from LA. In addition, this traffic congestion makes it more likely delayed flights eventually land very late at night. In July some of these congestion pressures should be relieved.
3. There is one additional reason to expect some improvement in the noise problems being reported. The FAA is testing out software that will optimize communication between air traffic controllers at hand-off points. Ideally this will increase the ability to understand what flights are likely to be stacking and to enable some additional coordination to prevent the need to vector off incoming planes. The implementation of this system will take some time.
4. The bottom line is that there has been an unfortunate conflagration of factors to increase air traffic, and air traffic noise, over our town. Some improvement should come in mid-summer,

and I will report back on any feedback I get on local airport traffic that may impact air traffic noise in town.
