2.1 Conclusion and Recommendations
• The results of the analysis indicate that the power density levels in the generally
accessible areas on the Utility Pole Level will not exceed the FCC's MPE limit
for General Population limit.
• The maximum theoretical % MPE is 18.06% directly in front of the antenna
beams at the Utility Pole Level.
• NOC and Guidelines signs need to be posted at the Monopole.
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:
Hickman Park Alt 1
• Street Address:
10014 238th Street SW
Edmonds, WA 98020
• Latitude:
474659.0" N
• Longitude:
122° 22' 0.35" W
• Structure Type:
Monopole
• Structure Height:
± 75' AGL
• Co -Locators/ Other Antennas: N/A
• BTS Equipment Location: The VZW equipment is located on the Ground.
Page 6 of 21
3.2 Site Configuration Being Modeled
• This is a Monopole application where Verizon antennas are mounted to pipes on
the Monopole behind Concealment Shroud for all sectors.
• This is a Three -Sector site supporting LTE at 700, 850, 1900, 2100 MHz, 5GNR
at 850MHz, CBRS at 3.6 GHz, and C-Band at 3700 MHz for all sectors. All LTE
assumes 4x4 MIMO.
• The values of the LTE antennas rad center of all sectors (61.8'), CBRS antennas
(70.4'), C-Band Antennas (73.3'), Adjacent Roof 1 Height (12'), Utility Pole
Height (37'), and Traffic Pole Height (35') are based on the CDs and RFDS.
These values must be verified on the site audit for the post study.
• The Adjacent Roof 2 has the same height as Adjacent Roof 1.
• 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.
4.1 Analysis Locations:
Number of Elevations Analyzed: 1
• Utility Pole Level.
• A study at the Adjacent Roofs and Ground levels was not required as the study at
the Utility Pole level shows that the MPE limit is below the General Population
MPE limit on the Adjacent Roofs and Ground levels.

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 -locator's 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.

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:

"Plane -wave equivalent power density
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 15 of 21
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 ensuring 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 framework 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:
