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.

G:\Planning\PDREPORT\DIRreports\2013\DIR-2013-20.doc 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. . ppp ,� e r� ���.����,._ � � � � .�,. —# .� '� �,_ . ,�... = ti'x � y.. .� "��- � ���� � .�'V� .�'�_ ,:T+�� .��A r � a �' ��, .y� _" ... � �n �k' � ' � .. � ��.��� $ �� ♦� � � � .�{� � �YYi1��� �'...Y� �_� � . ,� T dr t�a•��;� � ���`'� . ��w� �rr�� ��; ���rrw����;'� �� p��� �'� �'.
