DIR-2013-20b CITY OF CUPERTINO
10300 Torre Avenue, Cupertino, California 95014 (408) 777-3308
To: Mayor and City Council Members
Chairperson and Planning Commissioners .,
_ ,�'� �.� .
From: Aarti Shrivastava, Director of Community Development .-��%
Prepared by: George Schroeder, Associate Planner -
Date: July 18, 2013
Subject: Director's Minor Modification, DIR-2013-20, to an existing Use Permit (U-1984-18) to
allow the installation of a 13" x 13" microwave antenna and associated equipment on
the rooftop of an existing office building (Seagate) as part of a point-to-point wireless
network located at 20450 Stevens Creek Boulevard.
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.
DISCUSSION
The applicant, Heinz Werle, representing Seagate Technology and the property owner,
Prometheus, is requesting approval to allow the installation of a 13 inch x 13 inch microwave
antenna and an associated small-diameter mast on the rooftop of an existing office building
located at 20450 Stevens Creek Boulevard as part of a 5GHz (low power), non-Federal
Communications Commission (FCC) regulated, point-to-point wireless network between the
project site and the Seagate headquarters building located at 10200 South De Anza Boulevard.
The Director of Community Development previously approved the existing microwave
antenna and small-diameter mast atop the Seagate headquarters building in October 2012
(DIR-2012-34). The applicant proposes an additional antenna at the existing Seagate
headquarters site which does not require a separate planning approval.
The applicant proposes an antenna to be mounted onto a 5 foot tall, 2-inch diameter mast on
the rooftop of 20450 Stevens Creek Boulevard. The total height of the installation will be
approximately 115 feet above finish grade. Surrounding buildings and the building parapet
will obstruct public views to the new installation. The total setbacks from the adjacent
condominium at 20488 Stevens Creek Boulevard and adjacent apartments at 20380 and 20350
DIR-2013-20
20450 Stevens Creek Boulevard Page 2
Stevens Creek Boulevard will be greater than the ordinance-required 75 feet. Based on its
height and 20 foot minimum setback from the edge of the roof, it is within the height and
setback requirements of the City's Wireless Communications Facilities Ordinance.
An RF study was previously completed for the Seagate headquarters wireless site, 20400
Stevens Creek Boulevard, and 10001 North De Anza Boulevard in 2012, which assessed the
same equipment as proposed at 20450 Stevens Creek Boulevard The RF study demonstrated
that the maximum radio frequency exposure level in a worst case situation for a person
anywhere at the ground is 0.00012 mW/cm2, which is 0.012% of the applicable federal public
exposure limit and well within federal safety standards. The public exposure limit is reached
only within 2.5 inches in front of the antennas, so RF exposures to occupants on floors below
the antenna and nearest residents are also well within the federal safety standards.
ACTION
The Director of Community Development deems the modification minor and approves the
project with the following conditions of approval:
1. APPROVED EXHIBITS
Approval is based on exhibits titled: "Seagate Technology, Point-to-Point Wireless
Network Proposal, 20450 Stevens Creek Boulevard," prepared by Seagate Technology and
consisting of 5 sheets; except as may be amended by the conditions contained in this
resolution.
2. CAMOUFLAGING OF EQUIPMENT
The aerials and associated equipment shall be painted a flat gray or similar color in order to
minimize visibility. All cables shall be enclosed in a conduit painted to match the building
wall or roof color.
3. BUILDING PERMITS
The applicant shall consult with the City Building Division to obtain the necessary building
permits for the installation of the aerials and associated equipment.
4. ABANDONMENT
If after installation, the aerials and associated equipment are not used for its permitted
purpose for a continuous period of 18 months, said antennae and associated facilities shall
be removed. The applicant shall bear the entire cost of demolition and removal.
5. EXPIRATION DATE
DIR-2013-20
20450 Stevens Creek Boulevard Page 3
This Director's Minor Modification shall expire ten (10) years after the effective date of the
permit. The applicant may apply for a renewal of the minor modification at which time the
Director of Community Development may review the state of wireless communication and
camouflage technologies to determine if the visual impact of the personal wireless facility
can be reduced.
6. NOTICE OF FEES, DEDICATIONS, RESERVATIONS OR OTHER EXACTIONS
The Conditions of Project Approval set forth herein may include certain fees, dedication
requirements, reservation requirements, and other exactions. Pursuant to Government
Code Section 66020(d) (1), these Conditions constitute written notice of a statement of the
amount of such fees, and a description of the dedications, reservations, and other exactions.
You are hereby further notified that the 90-day approval period in which you may protest
these fees, dedications, reservations, and other exactions, pursuant to Government Code
Section 66020(a), has begun. If you fail to file a protest within this 90-day period complying
with all of the requirements of Section 66020, you will be legally barred from later
challenging such exactions.
This approval of the modification is effective July 18, 2013. The fourteen calendar day appeal
period will expire on August 1, 2013.

Seagate Technology
Point-to-Point Wireless Network Proposal
20450 Stevens Creek Boulevard
This document describes the proposed wireless network installation at one existing and one
new Seagate sites, located near the intersection of De Anza Boulevard and Stevens Creek Boulevard.
The affected locations are:
• 10200 South De Anza Blvd,Seagate location, "HQ" building, has existing installation
• 20450 Stevens Creek Blvd, new Seagate location, "Tower" building, new installation
The existing Cupertino site does have proper line of sight to the new location. Seagate intends
to install a SGHz, non-FCC regulated wireless system for use as a data connection between the locations.
The installation at each location consists of a 13x13-inch flat, grey antenna located on masts to provide
sufficient elevation for direct line of sight to provide the data link. The system currently has one
antenna deployed at the HQ location, and this proposal is to add one antenna to the existing location
and install another mast and antenna at the Tower location. Height and setback will be considered to
minimize visibility of the antennas from the street while maintaining the required line of sight. Existing
roof penetrations are another consideration for choosing the locations. New antenna location will be
approximately 140 horizontal feet from the Park Center Apartments (south), 200 feet from Montebello
condos(north), and 300 feet from City Center Apartments (east).
20450 Stevens Creek Blvd
The Tower location will have a single antenna installed on a new non-penetrating roof platform
set back from the north and west roofline. The setback of the new antenna is approximately 20 feet
from the west roof line, and 65 feet from the north roof line. The mast has a height of approximately 5
feet, and the roof height where the antenna is installed is approximately 115 feet. Extension above the
building parapet is approximately 3 feet.
