Date: March 6, 2018
Subject: Director’s Minor Modification, DIR-2018-05, to allow the installation of a
personal wireless service facility consisting of twelve panel antennas mounted on
a building rooftop behind an equipment screen and the construction of a
concealed base equipment station at 10335 North Tantau Avenue, APN 316-06-
064.
Chapter 19.164 of the Cupertino Municipal Code allows for administrative
approval of minor changes in a project. The Director reports his decision to the
City Council and Planning Commission in time to allow an appeal of the
decision within fourteen calendar days.
BACKGROUND
On behalf of the property owner, Apple, Inc., the applicant David Haddock of Ridge
Communications, representing Verizon Wireless, is requesting to install a personal wireless
service facility consisting of twelve panel antennas and associated equipment at 10335 North
Tantau Avenue. This is one of four proposed personal wireless service facilities proposed by
four different wireless carriers, coordinated by Apple, Inc. and located on the rooftop of one of
Apple’s four-story, office buildings. The property is zoned Planned Industrial Park, P(MP), and
is located just north of Highway 280. To the west is Calabazas Creek and a parking structure,
and to the north and east, other office/industrial buildings.
DISCUSSION
The proposed base equipment station is located entirely within the building basement and/or in
rooftop electrical room. Sections of the screen that cover the antennas will be replaced with a
radio-transparent material that matches the screen in color and design.
The purpose of the wireless facility is to primarily provide wireless coverage in the Apple
parking structure and implement its self-parking management program, but will have the
added benefit of providing coverage along Highway 280, adjacent Apple buildings and the
nearby residential neighborhood in the City of Santa Clara.

A joint radio frequency (RF) energy emissions exposure report was prepared by Hammett &
Edison, Inc., to analyze the cumulative RF energy exposure of all four wireless carriers
(Attachment B). The calculated RF exposures at the exposure points of concern are as follows:
Cumulative Maximum RF Energy Exposures
RF Exposure Location % of Cumulative Public Maximum Permissible
Exposure (MPE) Limit
Anywhere on ground level. 6.6%
Office floor just below the antennas 1.8%
Elevated parking structure 0.1%
nd
2 floor of nearest residence* 1.9%
*located at least 480 feet away from wireless antennas.
The RF consultant notes that RF exposure can be significant on certain portions of the rooftop in
front and around the antennas. The rooftop is inaccessible to the general public, but the
consultant recommends mitigation for wireless carrier technicians and maintenance staff who
service other rooftop equipment to prevent occupational exposures above Federal standards.
The consultant recommends explanatory signage at all roof-access doors/hatches and on the
roof screens in front of the antennas. The consultant also recommends appropriate RF safety
training to include personal monitor use and lockout/tagout procedures for all personnel and
contractors with rooftop access.
The proposed wireless facility complies with the City’s Wireless Communications Facilities
Ordinance (CMC 19.136) and conforms with the City’s Wireless Facilities Master Plan by
locating wireless facilities on existing non-residential buildings.
ACTION
The Director of Community Development deems the project categorically exempt from
environmental review under CEQA Guidelines, Article 19, Section 15301: Existing Facilities and
further deems the modification minor and approves the project with the following conditions of
approval:
