2.1 Conclusion and Recommendations
• The results of the analysis indicate that the power density levels in the generally
accessible areas on the Main Roof Level will exceed the FCC's MPE limit for 1 Ox
the Occupational MPE limit.
• The results of the analysis indicate that the power density levels in the generally
accessible areas on the Parking Level will not exceed the FCC's MPE limit for
General Population.
• The results of the analysis indicate that the power density levels in the generally
accessible areas on the Adjacent Roof 1 Level will not exceed the FCC's MPE
limit for General Population.
• The results of the analysis indicate that the power density levels in the generally
accessible areas on the Adjacent Roof 2 Level will not exceed the FCC's MPE
limit for General Population.
• The results of the analysis indicate that the power density levels in the generally
accessible areas on the Adjacent Roof 3 Level will not exceed the FCC's MPE
limit for General Population.
• The results of the analysis indicate that the power density levels in the generally
accessible areas on the Ground Level will not exceed the FCC's MPE limit for
General Population.
• The maximum theoretical % MPE is 1755% directly in front of antenna at the Main
Roof Level.
• NOC and Guidelines signs need to be posted at the inner side of the Access Hatch
to the Main Roof. All access points to these areas need to remain locked at all times.
• The Verizon's sectors contribute more than 5% to the areas in front of Sprint and
T-Mobile antennas (13, 14, 15, 16, 17, 18, 19, 22, 23 and 24). However, the
proposed mitigation covers this area of concern.
• This site will operate in general compliance with FCC OET Bulletin 65 and
Verizon's signage and barrier policy if the mitigation requirements outlined in the
Executive Summary are implemented.
Note: Modifications to the site; and/or increases in channel counts or power levels exceeding those listed in
this report will require additional evaluation to determine compliance.

3 Introduction
The purpose of this analysis and report is to evaluate the cumulative power density levels
of all non -excluded antennas located on the site and identify any areas of concern that
require mitigation. This report also assesses the site's compliance with FCC OET Bulletin
65; "Guidelines for Human Exposure to Radio -frequency Electromagnetic Fields".
The power density simulation performed for this site utilized RoofMaster® analysis
software. All antennas were assigned an operating frequency and transmit power and were
deemed to be operating at 100% of their rated output power.
3.1 Site Description:
• Site Name: Edmonds
• Street Address: 100 2nd Ave. S.
Seattle, WA 98020
• Latitude: 470 48' 42.7968" N
• Longitude: 1220 22' 51.9996" W
• Structure Type: Rooftop
• Structure Height: 145' AGL
• BTS Equipment Location: The Verizon equipment is located on the Grade below
Parking deck.
• Co -Locators/ Other Antennas: CD shows Co -Locator antennas. Since no co -
locator data was provided, a general antenna configuration was used modeling the
T-Mobile and Sprint carriers. However, until those details can be confirmed in the
Post analysis, (T-Mobile and Sprint) was used as an identifier in the report. C/Ls
were estimated from the CDs.
Page 6 of 31
3.2 Site Configuration Being Modeled
• This is a Rooftop application where Verizon antennas are mounted on pipes on the
Main Roof.
• This is a Three -Sector site supporting LTE at 700, 850, 1900, 2100 MHz, 5GNR at
850 MHz, C-Band at 3700 MHz, and CDMA for all sectors. All LTE assumes 4x4
MIMO.
• The values of the LTE antennas' rad center for all sectors (50.7'), CDMA antennas'
rad center for all sectors (51'), C-Band antennas' rad center for all sectors (51.7'),
Main Roof Height (45'), Parking Height (10'), Adjacent Roof 1 Height (33'),
Adjacent Roof 2 Height (14'), and Adjacent Roof 3 Height (23') are based on the
CDs, RFDS and Google Earth. These values must be verified on the site audit for
the post study.
• All technologies were evaluated assuming the maximum number of channels and
were running at maximum power 100% of the time.

4 Predictive Analysis Details
For purposes of this analysis, RoofMaster® was configured to provide an output based on
the appropriate MPE limit(s) published in the FCC's guidelines. The antenna information
was loaded into RoofMaster®, an MPE predictive analysis tool by Waterford Consultants,
LLC.

4.2 Antenna Inventory
The following table contains the technical data used to simulate the power density that may
be encountered with all antennas simultaneously operating at full rated power with the
exception of any excluded antennas cited in this document. If co -locators' antennas exist
and specific antenna details could not be secured, generic antennas, frequencies, and
transmit powers were used for modeling. The assumptions used are based on past
experience with communications carriers.

6 Conclusions and Recommendations
• The results of the analysis indicate that the power density levels in the generally
accessible areas on the Main Roof Level will exceed the FCC's MPE limit for 1 Ox
the Occupational MPE limit.
• The results of the analysis indicate that the power density levels in the generally
accessible areas on the Parking Level will not exceed the FCC's MPE limit for
General Population.
• The results of the analysis indicate that the power density levels in the generally
accessible areas on the Adjacent Roof 1 Level will not exceed the FCC's MPE
limit for General Population.
• The results of the analysis indicate that the power density levels in the generally
accessible areas on the Adjacent Roof 2 Level will not exceed the FCC's MPE
limit for General Population.
• The results of the analysis indicate that the power density levels in the generally
accessible areas on the Adjacent Roof 3 Level will not exceed the FCC's MPE
limit for General Population.
• The results of the analysis indicate that the power density levels in the generally
accessible areas on the Ground Level will not exceed the FCC's MPE limit for
General Population.
• The maximum theoretical % MPE is 1755% directly in front of antenna at the Main
Roof Level.
• NOC and Guidelines signs need to be posted at the inner side of the Access Hatch
to the Main Roof. All access points to these areas need to remain locked at all times.
• The Verizon's sectors contribute more than 5% to the areas in front of Sprint and
T-Mobile antennas (13, 14, 15, 16, 17, 18, 19, 22, 23 and 24). However, the
proposed mitigation covers this area of concern.
• This site will operate in general compliance with FCC OET Bulletin 65 and
Verizon's signage and barrier policy if the mitigation requirements outlined in the
Executive Summary are implemented.
Note: Modifications to the site; and/or increases in channel counts or power levels exceeding those listed in
this report will require additional evaluation to determine compliance.

7 Appendix A: FCC Compliance and RF Safety Policies
In August of 1997, the FCC published OET Bulletin 65 Edition 97-01 to regulate methods
for evaluating compliance with FCC guidelines for human exposure to radiofrequency (RF)
electromagnetic fields. The FCC guidelines for human exposure to RF electromagnetic
fields incorporate two categories of limits; namely "Controlled" (a.k.a. Occupational) and
"Uncontrolled" (a.k.a. General Public). The guidelines offer suggested methods for
evaluating fixed RF transmitters to ensure that the controlled and uncontrolled limits
deemed safe by the FC for human exposure are not exceeded.
OET Bulletin 65 recommended guidelines are intended to allow an applicant to "make a
reasonably quick determination as to whether a proposed facility is in compliance with the
limits." In addition, the guidelines offer alternate supplementary considerations and
procedures such as field measurements and more detailed analysis that should be used for
multiple emitter situations.
These guidelines define RF as emissions in the frequency range of 300 kHz to 100 GHz.
The FCC define Maximum Permissible Exposure (MPE) limits within this frequency range
based on limits recommended by the National Council on Radiation Protection and
Measurement, the Institute of Electrical and Electronics Engineers (IEEE), and by the
American National Standards Institute (ANSI).
The specific MPE limits defined by the FCC are as follows:

The FCC states that "Occupational/ Controlled limits apply in situations in which persons
are exposed as a consequence of their employment provided those persons are fully aware
of the potential for exposure and can exercise control over their exposure. Limits for
Occupational/ Controlled exposure also apply in situations when an individual is transient
through a location where Occupational/ Controlled limits apply provided he or she is made
aware of the potential for exposure."
Page 25 of 31
For General Population/ Uncontrolled limits, the FCC states that "General Population/
Uncontrolled exposures apply in situations in which the general public may be exposed, or
in which persons that are exposed as a consequence of their employment may not fully be
aware of the potential for exposure or cannot exercise control over their exposure."
For purposes of this analysis, all limits are evaluated against the Power Density limits.
Typical guidelines for determining whether Occupational/ Controlled limits can be applied
include insuring the environment (such as a rooftop) as limited/controlled access via locked
doors or physical barrier that are preferably controlled by a landlord that is aware of the
situation and can inform anyone going through the locked door of the existence of the RF
emissions. Such notification/awareness is typically accomplished by means of signage on
the door, or other access to the area of concern, as well as signage on or near the antennas.
Examples of such signs include the following:

8 Appendix B: Overview of RoofMaster® Functions and
Assumptions
RoofMaster® is a RF Compliance software package designed to enable the analysis,
assessment and mitigation of communications sites with respect to human exposure to
radiofrequency electromagnetic fields.
RoofMaster® was developed in 2008 by Waterford Consultants to support compliance
assessments performed at single and multi -operator wireless locations throughout North
America and has been in service since 2008. Real -world experience in evaluating
thousands of base station installations is reflected in the RoofMaster® design approach.
This document provides a guide for creating simulations of RF hazard conditions through
the characterization of antenna systems and site features and through FCC -specified
computational analysis.
On any structure, one may encounter antennas installed by wireless service providers,
public safety and other FCC -licensed and unlicensed operators. Siting constraints have
resulted in diverse and complex environments accessible to people performing a variety
of activities around these antennas. RoofMaster® supports the characterization of these
locations to convey important information regarding RF sources and accessible areas
necessary to evaluate the potential for human exposure to hazardous levels of RF
energy.
RoofMaster® supports the depiction of communications sites through the display of
construction drawing or aerial photography image files as well as providing line drawing
tools. These representations are scalable to enable the modeling of any location.
RoofMaster® utilizes a three-dimensional spatial ftamework consisting of a 1000 x 1000
grid with unlimited vertical dimensions necessary for the positioning of antennas and
modeling of RF conditions at each grid point throughout the space. Predictive analysis is
performed on a study plane at a specified elevation. The subsequent sections of this guide
provide the steps necessary to create a site representation and conduct these studies.
RoofMaster® employs several power density prediction models based on the
computational approaches set forth in the Federal Communications Commission's
Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency
Electromagnetic Fields, OET Bulletin 65. This guideline utilizes several antenna and
operational parameters in calculating the power density contributions from each emitter
at specified points throughout the study space. RoofMaster® enables antennas to be fully
defined in site specific aspects as well as through the use of a library of manufacturer
data. The parameters include:

In OET-65, the Cylindrical Model is presented as an approach to determine the spatially
averaged power density in the near field directly in front of an antenna. In order to
implement this model in all directions, RoofMaster® utilizes the antenna manufacturer
horizontal pattern data. Additionally, RoofMaster® incorporates factors that reduce the
power density by the inverse square of horizontal and vertical distance beyond the near
field region.
Power density is calculated as follows:
= ((360 -1 P!nGHH,V -) 11W
Beannvidth I 2;rRh Cn?'
• S is the spatially averaged power density value
• R is the horizontal distance meters to the study point
• h is the aperture length in meters
• Pin is power into the antenna input port in Watts
RoofMaster® Implementation:
• Gx is gain offset to study point as specified in manufacturer horizontal pattern
• Pin is adjusted by the portion of the antenna aperture in the 0-6 ft. vertical study
zone
• Hr accounts for 1/R2 Far Field roll off which starts at 2*h
• Vr accounts for 1/ (vertical distance)2 roll off from antenna bottom to the top of the
0-6 ft. study zone (or antenna top to bottom of 0-6 ft. study zone)
