The proposal consists of the installation of a 100’ mono-pine wireless communications facility. Your relevant forms, submittal requirements, and the applicable fees are submitted with this letter. Under the Telecommunications Act of 1996 (“Act”), you are required to take action on Vertical Bridge’s application “within a reasonable period of time.” In a 2009 declaratory ruling, the Federal Communications Commission established a legal presumption that a “reasonable period of time” means 150 days to act on an application for a new wireless facility (the “shot clock”). Because the proposed facility seeks to locate a new personal wireless service facility, the county must take action on Vertical Bridge’s application within 150 days. The shot clock begins to run the day the application is submitted. Here, the county must take final action no later than 150 days from today, or September 8, 2023. Vertical Bridge respectfully requests that this application be approved and any requisite building permit be issued as soon as possible but no later than September 8, 2023. If you have any questions regarding this application, please contact me.

Project Specific Location Address: 1491 Lower Honcut Road, Oroville, CA 95966 APN: 072-0330-009 Zoning: AG-20 Project Representative Maree Hoeger, Project Representative 1499 Huntington Dr. Suite 305, South Pasadena, CA 91030 949-280-2531 mhoeger@assurance-group.com Maree Hoeger Assurance Development obo Vertical Bridge mhoeger@assurance-group.com 949-280-2531 1499 Huntington Dr. Suite 305 South Pasadena, CA 91030 Vertical Bridge Project Name: CA-5437 Project Objectives To provide coverage in this area of the city, any combination or one of the following reasons may apply: • Coverage: No Service in the area (Indoor, Outdoor or Vehicular) and can apply specifically to the type of service provided (Voice or Data – 3G, 4G, 5G). Specifically, this proposed location addresses the following needs – o In-building Commercial – Subscriber anticipated to have accessibility to improved service while indoors within the city's commercially used spaces. o In-building – Subscriber anticipated to have accessibility to service while even indoors (i.e. residential homes) at lower performance levels. o In-vehicle- Subscriber anticipated to have accessibility to service while inside of vehicle. o Outdoor – Subscriber anticipated to have accessibility to improved service while outdoors. • Capacity: Proposed service in surrounding areas would be insufficient to meet anticipated demand by customers in and traversing through the area. Furthermore, proposed facilities servicing the surrounding area will be overloaded, preventing service, dropped calls or complete denial of service during peak usage hours. Below are coverage maps reflecting before and after coverage once the site is installed. SC60554 refers to the subject site.

We investigated two alternative sites within the search ring. At one site, the landlord was interested, however, the land is currently being used as a conservation easement. The allowable location will compromise the intended services in the desired coverage area and fail to support the residential area closer to Lower Honcut Road. At the second site, the location is south of the ring and further away from the intended coverage objective. The property where Vertical Bridge proposes to locate is one of the only spaces available that will meet the footprint requirements of the project. Additionally, Vertical Bridge received the landlord 's permission to pursue this project on their property. The county's setbacks and maximum height requirements are also adequately met on this parcel. It is for these reasons that Vertical Bridge is locating on the subject property and not on any other parcels within the search ring.

The proposed use and development is consistent with the General Plan and any applicable specific plans. A robust wireless network will contribute to the county's ability to respond to natural or man-made disasters and other public safety concerns in a potentially life-saving manner. 2. The site is adequate in size, shape, topography, location, utilities and other factors to accommodate the use and development. The site is of adequate size, shape, topography, location and access to utilities to accommodate the proposed wireless facility. The site is generally flat and has access to power and telephone connections that can be used for the project. The site is disguised as a tree in an effort to blend the tower with its preexisting surroundings. 3. Adequate street access and traffic capacity are or will be available to serve the proposed development as well as existing and anticipated development in the surrounding area. The facility is unmanned and will not contribute to any traffic. 4. Adequate utilities and public services are or will be available to serve the proposed development as well as existing and anticipated development in the surrounding area. The facility only requires power and telephone connections which are present in this area of the city. 5. The use and development will be compatible with the intended character of the area. The facility is designed to blend as much as possible with the surrounding environment that already exists within the vicinity.

Standards have been set based on peer- reviewed scientific studies and recommendations from a variety of oversight organizations, including the National Council on Radiation Protection and Measurements (NCRP), American National Standards Institute (ANSI), Institute of Electrical and Electronics Engineers (IEEE), Environmental Protection Agency (EPA), Federal Drug Administration (FDA), Occupational Safety and Health Administration (OSHA), and National Institute for Occupational Safety and Health (NIOSH). Although the purview of the public safety of RF emissions by the FCC was established by the Telecommunications Act of 1996, these standards remain under constant scrutiny. The typical urban cell site operates hundreds or even thousands of times below the FCC’s limits for safe exposure. All Vertical Bridge cell towers will operate well below these standards as well.

Every development project which requires a discretionary governmental approval will require at least some environmental review pursuant to CEQA, unless an exemption applies. The environmental review required imposes both procedural and substantive requirements. At a minimum, an initial review of the project and its environmental effects must be conducted. Depending upon the potential effects, a further and more substantial review may be conducted in the form of an environmental impact report (EIR). A project may not be approved if feasible alternatives or mitigation measures cannot substantially lessen the significant environmental effects of the project. At the state level, CEQA requires that public agencies consider the effects of their actions on historical resources eligible for listing on the California Register of Historical Resources. “Historical resource” refers to buildings, structures, sites (prehistoric and historic), objects, districts, and all manner of properties containing material remains of past human life or activity. The Department of Development Services utilizes the Northeast Information Center (NEIC) of the California Historical Resources Information System (CHRIS) to identify projects that may have archaeological significance. The CHRIS is a statewide system for managing information on the full range of historical resources identified in California. This system is under the authority and direction of the Office of Historic Preservation (OHP), the State Historic Preservation Officer (SHPO), and the State Historical Resources Commission (SHRC). The Northeast Center of the CHRIS system, located at California State University, Chico, manages the historical resource records for 11 counties, including Butte County. The Northeast Information Center will furnish a Record Search to Development Services indicating the archaeological/historical significance and sensitivity of the applicant’s project area and additionally providing a recommendation as to whether further archaeological survey is warranted. If further archaeological survey is required, the application would be considered incomplete until the appropriate archaeological survey is completed and reviewed.

Executive Summary T-Mobile proposes to install directional panel antennas on a tall pole, configured to resemble a pine tree, to be sited at 1491 Lower Honcut Road near Oroville. The proposed operation will comply with the FCC guidelines limiting public exposure to RF energy. Prevailing Exposure Standard The U.S. Congress requires that the Federal Communications Commission (“FCC”) evaluate its actions for possible significant impact on the environment. A summary of the FCC’s exposure limits is shown in Figure 1. These limits apply for continuous exposures and are intended to provide a prudent margin of safety for all persons, regardless of age, gender, size, or health. The most restrictive limit for exposures of unlimited duration at several wireless service bands are as follows: Transmit “Uncontrolled” Occupational Limit Wireless Service Band Frequency Public Limit (5 times Public) Microwave (point-to-point) 1–80 GHz 1.0 mW/cm2 5.0 mW/cm2 Millimeter-wave 24–47 1.0 5.0 Part 15 (WiFi & other unlicensed) 2–6 1.0 5.0 C-Band 3,700 MHz 1.0 5.0 BRS (Broadband Radio) 2,490 1.0 5.0 WCS (Wireless Communication) 2,305 1.0 5.0 AWS (Advanced Wireless) 2,110 1.0 5.0 PCS (Personal Communication) 1,930 1.0 5.0 Cellular 869 0.58 2.9 SMR (Specialized Mobile Radio) 854 0.57 2.85 700 MHz 716 0.48 2.4 600 MHz 617 0.41 2.05 [most restrictive frequency range] 30–300 0.20 1.0 Vertical Bridge • Site No. US-CA-5437 T-Mobile West LLC • Proposed Base Station No. SC60554A 1491 Lower Honcut Road • Oroville, California E9XE Page 2 of 4 ©2023 General Facility Requirements Base stations typically consist of two distinct parts: the electronic transceivers (also called “radios”) that are connected to the traditional wired telephone lines, and the antennas that send the wireless signals created by the radios out to be received by individual subscriber units. The transceivers are often located at ground level and are connected to the antennas by coaxial cables. Because of the short wavelength of the frequencies assigned by the FCC for wireless services, the antennas require line-of- sight paths for their signals to propagate well and so are installed at some height above ground. The antennas are designed to concentrate their energy toward the horizon, with very little energy wasted toward the sky or the ground. This means that it is generally not possible for exposure conditions to approach the maximum permissible exposure limits without being physically very near the antennas. Computer Modeling Method The FCC provides direction for determining compliance in its Office of Engineering and Technology Bulletin No. 65, “Evaluating Compliance with FCC-Specified Guidelines for Human Exposure to Radio Frequency Radiation,” dated August 1997. Figure 2 describes the calculation methodologies, reflecting the facts that a directional antenna’s radiation pattern is not fully formed at locations very close by (the “near-field” effect) and that at greater distances the power level from an energy source decreases with the square of the distance from it (the “inverse square law”). This methodology is an industry standard for evaluating RF exposure conditions and has been demonstrated through numerous field tests to be a conservative prediction of exposure levels. Site and Facility Description Based upon information provided by Vertical Bridge, including drawings by Assurance Development, dated February 21, 2023, T-Mobile proposes to install twelve directional panel antennas – three CommScope Model FFVV-65C-R3-V1, three Ericsson Model AIR6419, and six* antennas for future operation – on a 95-foot steel pole, configured to resemble a pine tree,† to be sited on the west side of a farm parcel to the east of Ahart Road, about 1,400 feet to the north of its intersection with School Street, in unincorporated Butte County, about 8 miles south of Oroville. The CommScope and Ericsson antennas would employ 2° and up to 19° downtilt, respectively, would be mounted at an effective height of about 91 feet above ground, and would be oriented in identical groups of four at about 120° spacing, to provide service in all directions. The maximum effective radiated power in any * It is recommended that the RF exposure conditions be re-evaluated for compliance with FCC limits at such time as these antennas are to be put into service. † Foliage atop the pole puts the overall height at about 100 feet. Vertical Bridge • Site No. US-CA-5437 T-Mobile West LLC • Proposed Base Station No. SC60554A 1491 Lower Honcut Road • Oroville, California E9XE Page 3 of 4 ©2023 direction would be 76,380 watts, representing simultaneous operation at 59,310 watts for BRS,‡ 6,200 watts for AWS, 5,430 watts for PCS, 1,900 watts for 700 MHz, and 3,540 watts for 600 MHz service. Also proposed to be located on the pole, at an effective height of about 86 feet above ground, is a microwave “dish” antenna, for interconnection of this site with others in the T-Mobile network. There are reported no other wireless telecommunications base stations at the site or nearby. Study Results For a person anywhere at ground, the maximum RF exposure level due to the proposed T-Mobile operation, including the contribution of the microwave dish, is calculated to be 0.020 mW/cm2, which is 2.4% of the applicable public exposure limit. The maximum calculated level at the second-floor elevation of any nearby residence§ is 2.0% of the public exposure limit. It should be noted that these results include several “worst-case” assumptions and therefore are expected to overstate actual power density levels from the proposed operation. No Recommended Mitigation Measures Due to their mounting location and height, the T-Mobile antennas would not be accessible to unauthorized persons, and so no measures are necessary to comply with the FCC public exposure guidelines. It is presumed that T-Mobile will, as an FCC licensee, take adequate steps to ensure that its employees or contractors receive appropriate training and comply with FCC occupational exposure guidelines whenever work is required near the antennas themselves. Conclusion Based on the information and analysis above, it is the undersigned’s professional opinion that operation of the base station proposed by T-Mobile West LLC at 1491 Lower Honcut Road near Oroville, California, will comply with the prevailing standards for limiting public exposure to radio frequency energy and, therefore, will not for this reason cause a significant impact on the environment. The highest calculated level in publicly accessible areas is much less than the prevailing standards allow for exposures of unlimited duration. This finding is consistent with measurements of actual exposure conditions taken at other operating base stations. ‡ The manufacturer reports that the antenna transmits 75% of the time in this band; this factor is incorporated into the calculations. A statistical factor of 32% is also included, to account for spatial distribution of served users, based on the United Nations International Telecommunication Union ITU-T Series K, Supplement 16, dated May 20, 2019. § Located about 280 feet to the southwest.

The FCC adopted the limits from Report No. 86, “Biological Effects and Exposure Criteria for Radiofrequency Electromagnetic Fields,” published in 1986 by the Congressionally chartered National Council on Radiation Protection and Measurements (“NCRP”). Separate limits apply for occupational and public exposure conditions, with the latter limits generally five times more restrictive. The more recent standard, developed by the Institute of Electrical and Electronics Engineers IEEE C95.1-, “SafetyLevels with Respect to Human Exposure to &MFDUSJD .BHOFUJD BOE Electromagnetic Fields, )[ to300 GHz,” includes similar limits.

The program uses the specific antenna patterns from the manufacturers and allows for the inclusion of uneven terrain in the vicinity, as well as any number of nearby buildings of varying heights, to obtain accurate projections of RF exposure levels. The program can account for spatial-averaging when antenna patterns are sufficiently narrow, and time- averaging is typically considered when operation is in single-frequency bands, which require time-sharing between the base station and the subscriber devices. OET-65 provides this formula for calculating power density in the far-field from an individual RF source: in mW/cm2power density where ERP = total Effective Radiated Power (all polarizations), in kilowatts, RFF = three-dimensional relative field factor toward point of calculation, and D = distance from antenna effective height to point of calculation, in meters. The factor of 2.56 accounts for the increase in power density due to reflections, assuming a reflection coefficient of 1.6 (1.6 x 1.6 = 2.56). This factor is typically used for all sources unless specific information from FCC filings by the manufacturer indicate that a different reflection coefficient would apply. The factor of 1.64 is the gain of a half-wave dipole relative to an isotropic radiator. The factor of 100 in the numerator converts to the desired units of power density. Because antennas are not true “point sources,” their signal patterns may not be fully formed at close distances and so exposure levels may be lower than otherwise calculated by the formula above. OET-65 recommends the cylindrical model formula below to account for this “near-field effect”: in mW/cm2 power density S = where Pnet = net power input to antenna, in watts, = half-power beamwidth of antenna, in degrees, D = distance from antenna effective height to point of calculation, in meters, and h = aperture height of antenna, in meters. The factor of 0.1 in the numerator converts to the desired units of power density. OET-65 confirms that the “crossover” point between the near- and far-field regions is best determined by finding where the calculations coincide from the two different formulas, and the program uses both formulas to calculate power density. 180 θBW × 0.1× Pnet π × D × h 0.1 x 16 x n x P x h2 0.1× 16 × η × Pnet π × h2 net BW 180 0.1 x Pnetx θ 180 θBW × 0.1× Pnet π × D × hx D x h 2.56 x 1.64 x 100 x RFF2 x ERP 4 x x D2 180 θBW × 0.1× Pnet π × D × hS = qBW 180 θBW × 0.1× Pnet π × D ×h 0.1 x 16 x n x P x h2 0.1× 16 × η × Pnet π × h2 net BW 180 0.1 x Pnetx0 180 θBW × 0.1× Pnet π × D × hx D x h 2.56 x 1.64 x 100 x RFF2 x ERP 4 x x D2 180 θBW × 0.1× Pnet π × D × hS = LOWER HONCUT RD PROJECT SITE AHART RDNO.DATE REVISIONS 0 3/20/23 JFYISSUED FOR SUBMITTAL BY CONTACT : JOYCE YU EMAIL : SIMS@DRAFTLINK.COM PHONE : 949-232-5045 WWW.DRAFTLINK.COM 1 04/10/23 JFYISSUED FOR SUBMITTAL US-CA-5437 NORTH HONCUT 1491 LOWER HONCUT ROAD OROVILLE, CA 95966 PROPOSED EXISTING AERIAL MAP COPYRIGHT: GOOGLE MAPS, 2023 PANEL ANTENNAS AND RRU'S PAINTED TO MATCH MONOPINE FOLIAGE VIEW SHEET A A 1 /3 DISCLAIMER: THIS IS A RENDERING REPRESENTATION OF THE PROPOSED PROJECT ONLY PHOTO PROVIDED BY: ASSURANCE DEVELOPMENT 'VERTICAL BRIDGE' 100'H CO-LOCATABLE MONOPINE 'VERTICAL BRIDGE' 40' X 40' LEASE AREA WITH 8'-0"H CHAIN LINK FENCED COMPOUND 'VERTICAL BRIDGE' 20'-0" WIDE BEHLEN COUNTRY GATE NO.DATE REVISIONS 0 3/20/23 JFYISSUED FOR SUBMITTAL BY CONTACT : JOYCE YU EMAIL : SIMS@DRAFTLINK.COM PHONE : 949-232-5045 WWW.DRAFTLINK.COM 1 04/10/23 JFYISSUED FOR SUBMITTAL US-CA-5437 NORTH HONCUT 1491 LOWER HONCUT ROAD OROVILLE, CA 95966 LOWER HONCUT RD PROJECT SITE AHART RDPROPOSED EXISTING AERIAL MAP COPYRIGHT: GOOGLE MAPS, 2023 VIEW 2 / 3 SHEET B B DISCLAIMER: THIS IS A RENDERING REPRESENTATION OF THE PROPOSED PROJECT ONLY PHOTO PROVIDED BY: ASSURANCE DEVELOPMENT PANEL ANTENNAS AND RRU'S PAINTED TO MATCH MONOPINE FOLIAGE 'VERTICAL BRIDGE' 100'H CO-LOCATABLE MONOPINE 'VERTICAL BRIDGE' 40' X 40' LEASE AREA WITH 8'-0"H CHAIN LINK FENCED COMPOUND 'VERTICAL BRIDGE' 20'-0" WIDE BEHLEN COUNTRY GATE LOWER HONCUT RD PROJECT SITE AHART RDNO.DATE REVISIONS 0 3/20/23 JFYISSUED FOR SUBMITTAL BY CONTACT : JOYCE YU EMAIL : SIMS@DRAFTLINK.COM PHONE : 949-232-5045 WWW.DRAFTLINK.COM 1 04/10/23 JFYISSUED FOR SUBMITTAL US-CA-5437 NORTH HONCUT 1491 LOWER HONCUT ROAD OROVILLE, CA 95966 PROPOSED EXISTING AERIAL MAP COPYRIGHT: GOOGLE MAPS, 2023 VIEW 3 / 3 SHEET C C DISCLAIMER: THIS IS A RENDERING REPRESENTATION OF THE PROPOSED PROJECT ONLY PHOTO PROVIDED BY: ASSURANCE DEVELOPMENT 'VERTICAL BRIDGE' 100'H CO-LOCATABLE MONOPINE 23072 LAKE CENTER DR., SUITE 211LAKE FOREST, CA 92630714.624.9027LS-1TITLE SHEETNO.SUBMITTAL / REVISIONDRAWN:DESIGNED:CHECKED:LJAJKPROJECT NUMBER:US-CA-5437PROJECT TITLE:US-CA-5437SC60554MATERSON WAY1491 LOWER HONCUT RD.,OROVILLE, CA 95966ENGINEER STAMP:DATEDRAWING TITLE:DRAWING SCALE:AS NOTEDDATE:03/02/2023DRAWING NUMBER:BYUNAUTHORIZED ALTERATION OR ADDITION TOTHIS DOCUMENT IS A VIOLATION OFAPPLICABLE STATE AND / OR LOCAL LAWS750 PARK OF COMMERCE DR.SUITE 200 | BOCA RATON, FL | 33487561.948.6367SITE ACQUISITION1499 HUNTINGTON DR. | SUITE 305SOUTH PASADENA, CA | 91030626.765.5079SURVEY PREPARED FOR:ENGINEERVB BTS II, LLC0PRELIMINARY SURVEYLJ2/15/23—(THE EXCEPTION IS A STANDARD EXCEPTION AND NOT THE TYPE TO BE DEPICTED HEREON)(THE EXCEPTION IS A STANDARD EXCEPTION AND NOT THE TYPE TO BE DEPICTED HEREON)(THE EXCEPTION IS A STANDARD EXCEPTION AND NOT THE TYPE TO BE DEPICTED HEREON)(THE EXCEPTION IS A STANDARD EXCEPTION AND NOT THE TYPE TO BE DEPICTED HEREON)(THE EXCEPTION IS A STANDARD EXCEPTION AND NOT THE TYPE TO BE DEPICTED HEREON)1FINAL SURVEYLJ03/02/23 23072 LAKE CENTER DR., SUITE 211LAKE FOREST, CA 92630714.624.9027LS-2TOPOGRAPHIC SURVEYNO.SUBMITTAL / REVISIONDRAWN:DESIGNED:CHECKED:LJAJKPROJECT NUMBER:US-CA-5437PROJECT TITLE:US-CA-5437SC60554MATERSON WAY1491 LOWER HONCUT RD.,OROVILLE, CA 95966ENGINEER STAMP:DATEDRAWING TITLE:DRAWING SCALE:AS NOTEDDATE:03/02/2023DRAWING NUMBER:BYUNAUTHORIZED ALTERATION OR ADDITION TOTHIS DOCUMENT IS A VIOLATION OFAPPLICABLE STATE AND / OR LOCAL LAWS750 PARK OF COMMERCE DR.SUITE 200 | BOCA RATON, FL | 33487561.948.6367SITE ACQUISITION1499 HUNTINGTON DR. | SUITE 305SOUTH PASADENA, CA | 91030626.765.5079SURVEY PREPARED FOR:ENGINEERVB BTS II, LLC0PRELIMINARY SURVEYLJ2/15/23LEASE AREAACCESS AND UTILITY EASEMENT1FINAL SURVEYLJ03/02/23
