This analysis assumes that the existing structures, structure modifications and associated components have been properly constructed per original design and have been well maintained. The loads considered in this analysis were determined in accordance with the requirements of the California Building Code, 2019 Edition, and the ANSI/TIA-222-H (Structural Standard for Antenna Supporting Structures and Antennas) for an ultimate design wind speed of 96 mph for San Diego County, California. Ss=0.941g, S,=0.345g, Site Class D, Risk Category II. Our findings show that the existing mounts will be adequate to support AT&T's equipment installation. The new antennas will be installed on the mounts inside the existing FRP enclosure. The analysis is based solely on information available to us as listed on the following page. This report is considered void if any of the listed information is incorrect. We trust that this report is satisfactory. If you have any questions regarding the analysis, please contact our office.

FCC OET Bulletin 65 -Edition 97-01 recommends that theoretical calculations should be done to yield a worst-case scenario. This theoretical analysis will provide a worst-case assessment of potential emissions and will assume all transmitters are operating at highest capacity and power. This will provide AT&T with a guideline of how to proceed with mitigating the site to ensure the site will be compliant with FCC regulations at any instance. Most licensed wireless system operators are required to perform periodic assessments of potential impacts to humans due to radio frequency emissions from active transmitters at the site. The Federal Communications Commission ("FCC") considers two levels of standards based on access controls to the site and the level of knowledge of the effects of radio frequency to humans. A controlled/occupational environment assumes that anyone accessing the site is fully trained in RF safety and is aware of the effects of the exposure to radio frequency emissions to humans. An uncontrolled/general population environment assumes that access is not restricted to RF trained individuals and other members of the general population may be able to access the site for any reason, occupation or otherwise. 2.0 Results Snapshot and Mitigation Measures Based on the theoretical modeling analysis performed, there are areas that exceed the FCC's General Population and/or Occupational limits at this site. AT&T must ensure proper mitigation is installed at the site in order to bring the site into compliance. Signage and barriers are the primary means of mitigating access to accessible areas of exposure. A site scaled map can be found in section 3.0 which details the locations where mitigation should be installed to bring the site into compliance with FCC regulations. To reduce the risk of exposure, Fox Hill Telecom recommends that access to areas associated with the active antenna installation be restricted and secured where possible. CAL00509_5D0509 / Bressi Ranch Boys and Girls Club/ 12854532 Below is a summary of recommended mitigation at this AT&T facility.

Page 15 CAL00509_SD0S09 / Bressi Ranch Boys and Girls Club/ 12854532 4.0 Results and Compliance Recommendations Based on the t heoretical modeling analysis performed, there are areas accessible to the General Population t hat exceed the FCC's General Population and/or Occupational limits at this site. AT&T must ensure proper mitigation is inst alled at the site in order to bring the site into compliance for areas near the ant ennas that may exceed the FCC's General Population and/or Occupational. At the main roof level (31.67' AGL), the maximum power density value(% MPE) calculated for AT&T's antennas is 1,613.23 % of the FCC's allowable limit for General Population exposure to radio frequency emissions (322.65 % of the FCC's allowable Occupational limit). At the ground level (O' AGL), t he maximum power density value(% M PE) calculated for AT&T's antennas is 4.14 % of the FCC's allowable limit for General Popu lation exposure to radio frequency emissions (0.83 % of the FCC's allowable Occupational limit). The FCC mandates that if a site is found to be out of compliance with regard to emissions that any system operator contributing 5% or more to areas exceeding t he FCC's allowable limits, as outlined in this report, w ill be responsible for bringing the site into compliance. There are no antennas from other carriers located at this site.

The FCC regulates Maximum Permissible Exposure in units of microwatts per square centimeter (µW/cm2). The number of µW/cm2 ca lculated at each sample point is called the power density. The exposure limit for power density varies depending upon the frequencies being utilized. Wireless Carriers and Paging Services use different frequency bands each with different exposure limits, therefore it is necessary to report results and limits in terms of percent MPE rather t han power density. All results were compared to the FCC (Federal Communications Commission) radio frequency exposure rules, 47 CFR l.1307(b)(l) -(b)(3), to determine compliance with the Maximum Permissible Exposure (MPE) limits for General Population/Uncontrolled environment s as defined below. General Population/Uncontrolled exposure limits apply to situations in which the general public may be exposed or in which persons who are exposed as a consequence of their employment may not be made fully aware of the potential for exposure or cannot exercise control over their exposure. Therefore, members of the general public would always be considered under this category when exposure is not employment related, for example, in the case of a telecommunications tower that exposes persons in a nearby residential area. Public exposure to radio frequencies is regulated and enforced in units of microwatts pe r square centimeter (µW/cm2). The general population exposure limit for the 700 and 800 MHz Bands is approximately 467 µW/cm2 and 567 µW/cm2 respectively, and the general population exposure limit for the 1900 MHz PCS and 2100 MHz AWS bands is 1000 µW/cm2. Because each carrier will be using different frequency bands, and each frequency band has different exposure limits, it is necessary to report percent of MPE rather than power density. Occupational/Controlled exposure limits apply to situations in which persons are exposed as a conseq uence of their employment and in which those persons who are exposed have been made fully aware of the potential for exposure, have been properly trained in RF safety and can exercise control over their exposure. Occupational/Controlled exposure limits also apply where exposure is of a transient nature as a result of incident al passage through a location where exposure levels may be above general population/uncontrolled limits (see below), as long as the exposed person has been made fully aware of the potential for exposure, have been trained in RF safety and can exercise control over his or her exposure by leaving the area or by some other appropriate means. The Occupational/Controlled exposure limits all utilized frequency bands is five (5) times the FCC's General Public/ Uncontrolled exposure limit.

All calculations have been performed using Waterford Consultants' RoofMaster™ 2015 Version 19.9.7.19. RoofMaster™ employs several power density prediction models based on the computational approaches set forth in the Federal Communications Commission's Eva luating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields, OET Bulletin 65 utilizing both cylindrical and far-field modelling (calculated using antenna manufacturers pattern data). For this analysis, power density calculations were performed by Fox Hill Telecom on two antenna models including a stat ic beam antenna used for the UMTS and 4G radios and a dynamic beam-forming antenna for the 5G radio broadcast. The static beam results in a fixed coverage area based upon the electrical characteristics of the antenna as specified by the antenna man ufacturer. The dynamic beam-forming antenna functions by allowing the carrier to shift a narrow "talk channel" beam to each user in the antennas service area for the provision of service to the user's device by varying the phase of transmission by each active element in the element array inside the antenna to produce the desired resulting vector for the narrow beam. This allows greater gain in a given direction while producing intentional nulls in non-service areas to produce greater signal quality. For the power density calculations for the UMTS / 4G static beam antennas the Cylindrical (Sula9) model was used to allow for a more pessimistic approach resulting from the transmission power being captured within the 3dB power roll off points of the antennas horizontal pattern. Calculations performed for the narrow beam 5G Traffic Beams were performed using a Far Field model based upon the antenna manufacturers antenna pattern data for both horizontal and vertical gain values. The selection of the Far Field model was done to prevent large overprediction areas of power density values close in to the antenna resulting from the extremely narrow window produced by the 3db power roll off points which define the power spreading area with a Cylindrical Model. Both models are discussed in further detail below. A statistical factor which reduces the transmit power of the SG beam forming antennas identified in this report to 32% of maximum theoretical transmit power for this antenna was used in the outlined calculations. This factor was utilized to account for t he spatial distribution of users, network utilization, time division duplexing, and scheduling time typically experienced in these dynamic radio environments. This power factor more accurately predicts the emitted radio frequency energy in any given direction based upon test results from the antenna system manufacturers and AT&T recommends the use of this factor based on this guidance from its antenna system manufacturers as well as supporting international industry standards, industry publications, and its extensive experience. Pa g c I 10 CAL00509_SD0509 / Bressi Ranch Boys and Girls Club/ 12854532 The Cylindrical Model Implementation (Sula9) 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: • Sis 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: • GH 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 • H, accounts for 1/R2 Far Field roll off which starts at 2xh • V, accounts for 1/ (vertical distance)2 roll off from antenna bottom to the top of the 0-6ft study zone (or antenna top to bottom of 0-6ft study zone) z I ! .......... .

Page 111 CAL00509_SD0509 / Bressi Ranch Boys and Girls Club/ 12854532 The Far Field Model In OET-65, a far field model is presented to calculate the spatial peak power density. The RoofMaster™ implementation of this model incorporates antenna manufacturer's horizontal and vertical pattern data to determine the power density in all directions. Power density is calculated as follows: S= 13.0SP,,,G pTV R 2 C/112 • Does not include 100% reflection factor • P;n is Watts • R is meters to study point • G is gain to study point as specified in manufacturer horizontal and vertical patterns A worst-case prediction is described in OET-65 where field strength may double due to 100% reflection of the incoming radiation. Considering an EPA recommendation that a multiplier of 1.6 is a more realistically representation of this effect is rewritten as follow: This model yields the power density at a single point in space. In order to determine t he spat ial power density for comparison to the FCC limits, the average of several points calculated within the human profile (Oto 6 feet) must be conducted. RoofMaster™ calculates seven power density values between 0 and 6 feet above the specified study plane and performs a linear spatial average. far Field ·································•······································································•··611 ...... .
