LANDS OF PURISSD/1A HILLS WATER DISTRICT (APPLICANT: AT&T); 27299 ARASTRADERO ROAD; FILE # 23 -11 -CUP -VAR FROM: Nicole Horvitz, Assistant Planner APPROVED: Debbie Pedro, AICP, Planning Directoy RECOMMENDATION: That the Planning Commission: Forward a recommendation to the City Council to approve the requested Conditional Use Permit renewal, modifications, and variance for the existing/previously approved wireless communications facility, subject to the amended Conditions of Approval in Attachment 1 and Findings of Approval in Attachment 2. BACKGROUND On February 16, 2006, the City Council approved the installation of a new monopine to be constructed by Cingular Wireless (now AT&T) and a setback variance for the monopine and associated ground equipment. The 5,292 square foot (.12 acre) property is located at the intersection of Arastradero and Purissima Roads. The property is currently used as a pump station for Purissima Hills Water District. The existing development on the site consists of a monopine, ground equipment cabinets for AT&T, a fresh water pump station, access driveway, electrical cabinets, and a portable backup generator. DISCUSSION The existing wireless communications facility consists of a 93' tall (87' tall pole with 6' tall branches) monopine at the south end of the Purissima Hills Water District property. Six (6) AT&T panel antennas are currently mounted on the pole at 86' from grade and three (3) new ground equipment cabinets are proposed in addition to existing ground equipment. The three (3) new panel antennas (52" H x 12" W x 8" D) are located 79' from grade, six (6) new RRU's are mounted at 75' from grade and three (3) new ground equipment cabinets on two (2) new concrete pads will be located within the same vicinity as the existing cabinets. Staff Report to the Planning Commission Lands of Purissima Hills Water District November 3, 2011 Page 2 of 7 The proposed modifications to the existing wireless facility are for the new LTE (Long Term Evolution) 4G technology and will increase data speed and the ability to uplink and downlink for cell phones and handheld devices. A radio frequency (RF) analysis for the project was submitted by EBI Consulting dated May 5, 2011. The report concludes that all of the existing and proposed wireless service, will comply with the FCC's current prevailing standard for limiting human exposure to RF energy. Therefore, no significant RF energy impact on the environment or population is expected (Attachment 4). Pursuant to Government Code Section 65964 (b) the duration of time for any permit renewal for a wireless telecommunications facility shall be a minimum of 10 years. Staff has amended condition of approval # 3 in Attachment 1 to comply with State Law. VARIANCE Per Section 10-1.505 of the Los Altos Hills Municipal Code, "no structure, nor portion thereof, other than driveways, including necessary backup areas; walkways; minor ornamental garden structures subject to the height limits specified in Section 10-1.504(f); fences; driveway light fixtures, limited to one fixture on each side of a driveway, for a maximum of two (2) fixtures per lot, subject to the height limits specified in Section 10-1.504(h); or underground utility facilities, shall be constructed, altered, or maintained so as to be located between the property line and any setback line." The applicant's request is to install the three (3) new ground equipment cabinets on a 3'x4' concrete pad and a 7'x 6' concrete pad, which will encroach within the front, side, and rear property line setback. Due the shape and size of the property, there is no feasible way for the applicant to comply with the setback requirements. Two (2) of the ground cabinets ( 29" H x 24" W x 20" D) will be stacked one on top of the other and the third cabinet (72" H x 30" W x 36.1" D) will stand alone. The findings contained in Attachment 2 must be made in the affirmative in order for this application to be approved. Due to the unique shape and size of the parcel and that it is surrounded on three sides by undeveloped non-residential parcels is an exceptional and extraordinary circumstance that warrants the variance request. AESTHETICS The antennas will be subject to the same aesthetic conditions as the approved AT&T monopine and antennas. The materials, colors, and design used to screen the antennas must match the AT&T antenna installation. The antennas will be painted to match the existing antennas and screened with sufficient artificial vegetation to resemble a healthy mature pine tree. Staff Report to the Planning Commission Lands of Purissima Hills Water District November 3, 2011 Page 3 of 7 CONCLUSION The proposed facility is consistent with the Town's Wireless Communications Facilities Policy due to its non-residential site, visual impacts are minimized by the location of the antennas and the landscape screening shields the view of the facility from off site. In addition the applicant has submitted a report demonstrating that the proposed facility will operate within federal RF emissions standards and guidelines. CEQA STATUS The proposed application is exempt from California Environmental Quality Act (CEQA) pursuant to Section 15301(a) of the CEQA Guidelines. ATTACHMENTS 1. Amended Conditions of Approval 2.

Attachment 2 Staff Report to the Planning Commission Lands of Purissima Hills Water District November 3, 2011 Page 7 of 7 ATTACHMENT 2 FINDINGS OF APPROVAL FOR A SETBACK VARIANCE WIRELESS COMMUNICATIONS FACLITY (AT&T) LANDS OF PURISSIMA HILLS WATER DISTRICT 27299 ARASTRADERO ROAD FILE# 23 -11 -CUP -VAR 1. Because of exceptional and extraordinary circumstances applicable to the subject property, including size, shape, topography, location or surroundings, the strict application of the provisions of this Title is found to deprive such property of privileges enjoyed by other properties in the vicinity and under identical zoning classification; The small (0.12 acre), Purissima Hills Water District property is surrounded on three sides by undeveloped Stanford lands and Interstate 280. The size and shape of the property necessitates a setback variance for any development on the site; the entire site is located within the required setbacks. Furthermore, the siting of the existing pump house and site circulation pattern limit the siting options for the proposed ground equipment. The strict application of the provisions of this Title creates a hardship by rendering the site unusable. 2. Upon the granting of the variance, the intent and purpose of the applicable sections of the Zoning Ordinance will still be served and the recipient of the variance will not be granted special privileges not enjoyed by other surrounding property owners. The proposed location of the ground equipment is furthest from neighboring development (residence over 400' away). This would not be a grant of special privilege because the Town has granted a setback Variance for wireless proposals with previous applications and the size lots of this size are very rare in Town. In addition, the property is unique in that the adjoining properties are all nonresidential sites including an interstate highway and undeveloped Stanford University lands that negate the purpose for the Town's normal setback requirements. 3. The granting of such variance will not be materially detrimental to the public welfare or injurious to the property, improvements or uses within the immediate vicinity and within the same zoning district. The granting of the Variance for encroachment into the setback would limit potential impacts to neighbors or property owners because the proposed location of the ground equipment is at the furthest distance when measured from adjacent development. The proposed antennas and ground equipment meet the FCC limits for human exposure and the installations will be completed to Building Code standards. No detriment to public welfare is anticipated.

The Scope of Work would include the following: three new additional antennas mounted at the height of 79% six remote radio units (RRU's) mounted at the height of 75'; one fiber dome unit; one GPS antenna; and two equipment cabinets at the base of the tower. No increase in height, or other substantial modification to the facility would occur which would substantially alter the visual appearance of the facility. The new tower equipment will be for the most part screened by the foliage on the existing monopine and will look similar to the existing antennas installations. The ground mounted equipment will be within the existing fenced area and will .not be visible to the general public. Antenna idlaster Plan: Because "of the rapid pace that the wireless technology is evolving it is difficult to provide an accurate Antenna Master Plan. Furthermore, there are numerous other variables that effect the planning of the ATT wireless network. With that being said ATT Mobility will be proposing to modify the following facilities this year: 26379 Freemont Road and 26451 Arastradero Road. The modifications will be similar in scope of what is being proposed with this application. These modifications will upgrade the network in this area to provide Long Term Evolution (LTE) technology. In simple terms, LTE technology is the next generation of wireless network which will provide significantly faster data to mobile devises.

This report summarizes the results of RF-EME monitoring and modeling in relation to relevant FCC RF-EME compliance standards for limiting human exposure to RF-EME fields. rp ' !gyp .This report contains a detailed summary of the RF EME analysis for the site, including the following: ■ Antenna Inventory ■ Site Plan with antenna locations ■ Antenna inventory with relevant parameters for theoretical modeling ■ Graphical representation of theoretical MPE fields based on modeling • Graphical representation of recommended signage and/or barriers • Site Photographs ■ Site Plan with Monitoring Locations ■ Site Survey Data This document addresses the compliance of AT&T's transmitting facilities independently and in relation to all collocated facilities at the site. Statement of Compliance A site is considered out of compliance with FCC regulations if there are areas that exceed the FCC exposure limits and there are no RF hazard mitigation measures in place. Any carrier which has an installation that contributes more than 5% of the applicable MPE must participate in mitigating these RF hazards.: As presented in the sections below, based on worst-case predictive modeling and an RF EME monitoring survey, there are no modeled or measured exposures on any accessible ground -level walking/working surface related to proposed or existing antennas that exceed the FCC's occupational or general public exposure limits at this site. The composite exposure level from all carriers on this site is approximately 12.56 percent of the FCC's general public limit (2.51 percent of the FCC's occupational limit) at the nearest walking/working surface to each antenna (i.e., the ground). AT&T Recommended Signage/Compliance Plan AT&T's RF Exposure Policy guidance, dated March 31, 2009, requires that: 1. All sites must be analyzed for RF exposure compliance; 2. All sites must have that analysis documented; and 3. All sites must have any necessary signage and barriers installed. ga-51 21 B Street 4 Burlington, MA 01803 + 1.800.786.2346 RF-EME Compliance Report USID No. 85230 Site No. CNU3657 ESI Project No. 62102044 Arastradero Rd E of 1-280, Los Altos Hills, California Site compliance recommendations have been developed based upon protocols presented in AT&T's RF Exposure Policy guidance document, dated March 31, 2009, additional guidance provided by AT&T, EBI's understanding of FCC and OSHA requirements, and common industry practice. Barrier locations have been identified (when required) based on guidance presented in AT&T's RF Exposure Policy guidance document, dated March 31, 2009. The following signage is recommended at this site: ■ Green INFO I sign posted at the base of the monotree ■ Yellow CAUTION sign posted on or next to the access gate(s) The signage proposed for installation at this site complies with AT&T's RF Exposure Policy and therefore complies with FCC and OSHA requirements. No barriers are recommended for this site. More detailed information concerning site compliance recommendations is presented in Section 5.0 and Appendix E of this report. _----_--,_a_:=.

There are three Sectors (A, B, and C) at the site, with one (1) antenna proposed to be installed per sector, bringing the total number of AT&T antennas to three (3) per sector. For modeling purposes, it is assumed that there will be one (1) UMTS antenna in each sector transmitting in the 850 and 1900 MHz frequency ranges, one (1) GSM antenna in each sector transmitting in the 850 and 1900 MHz frequency ranges and one (1) LTE antenna in each sector transmitting in the 700 and 1710 MHz frequency ranges. Both existing and proposed antennas were included in the modeling analysis. The Sector A GSM and UMTS antennas will be oriented 40° from true north and the LTE antenna will be oriented 45° from true north. The Sector B antennas will be oriented 290° from true north. The Sector C GSM and UMTS antennas will be oriented 190° from true north and the LTE antenna will be oriented 180° from true north. The bottoms of the GSM and UMTS antennas will be 76.85 feet above ground leveland the bottoms of the LTE antennas will be 70.85 feet above ground level. Appendix B presents an antenna inventory for the site. Access to this site is accomplished. via a gate in the fence surrounding the monotree . Workers must be elevated to antenna level to access them, so these antennas are not accessible to the general public. EBI conducted a site visit on April 24, 201 1 . At the time of the site visit there were no other carriers observed on the monotree. Measurements were taken at ground level to record ambient RF-EME levels of other potential antennas that might be present, though unobserved, in the vicinity. These results were added to the predictive modeling results for the AT&T antennas to calculate the cumulative .worst- case MPE levels for the site after installation of the proposed AT&T equipment, as reported in Section 4.0. Appendix F contains site photos taken on April 24, 2011 during the on-site. survey. Appendix G presents a site plan indicating monitoring and antenna locations. Appendix H contains climate and site observations recorded during the site visit. 2.0 FEDERAL COMMUNICATIONS COMMISSION (FCC) REQUIREMENTS The FCC has established Maximum Permissible Exposure (MPE) limits for human exposure to Radiofrequency Electromagnetic (RF-EME) energy fields, based on exposure limits recommended by the National Council on Radiation Protection and Measurements (NCRP) and, over a wide range of frequencies,'the exposure limits developed by the Institute of Electrical and Electronics Engineers, Inc. (IEEE) and adopted by the American National Standards Institute (ANSI) to replace the 1982 ANSI guidelines. Limits for localized absorption are based on recommendations of both ANSI/IEEE and NCRP. The FCC guidelines incorporate two separate tiers of exposure limits that are based upon occupational/controlled exposure limits (for workers) and general public/uncontrolled exposure limits for members of the general public. Occupation allcontrolled exposure limits apply to situations in which persons are exposed as a consequence of their employment and in which those persons who are exposed have been made fully aware of the potential for exposure and can exercise control over their exposure. Occupational/ controlled exposure limits also apply where exposure is of a transient nature as a result of incidental passage through a location where exposure levels may be above general public/uncontrolled limits (see EBI 21 B Street 4 Burlington, MA 01803 a 1.800.786.2346 3 RF-EME Compliance Report USID No. 85230 Site No. CNU3657 EBI Project No. 62102044 Arastradero Rd E of 1-280, Los Altos Hills, California below), as long as the exposed person has been made fully aware of the potential for exposure and can exercise control over his or her exposure by leaving the area or by some other appropriate means. General public/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. Table I and Figure I (below), which are included within the FCC's OET Bulletin 65, summarize the MPE limits for RF emissions. These limits are designed to provide a substantial margin of safety. They vary by frequency to take into account the different types of equipment that may be in operation at a particular facility and are "time -averaged" limits to reflect different durations resulting from controlled and uncontrolled exposures. The FCC's MPEs are measured in terms of power (mW) over a unit surface area (cm2). Known as the power density, the FCC has established an occupational MPE of 5 milliwatts per square centimeter (mW/cm2) and an uncontrolled MPE of I mW/cm2 for equipment operating in the 1900 MHz frequency range. For the AT&T equipment operating at 850 MHz, the FCC's occupational MPE is 2.83 mW/cm2 and an uncontrolled MPE of 0.57 mW/cm2. These limits are considered protective of these populations.

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. Personal Communication (PCS) facilities used by AT&T in this area operate within a frequency range of 850-1900 MHz. Facilities typically consist of. 1) electronic transceivers (the radios or cabinets) connected to wired telephone lines; and 2) antennas that send the wireless signals created by the transceivers to be received by individual subscriber units (PCS telephones). Transceivers are typically connected to antennas by coaxial cables. Because of the short wavelength: of PCS services, the antennas require line -of -site paths for good propagation, and are typically installed above ground level. Antennas are constructed to concentrate energy towards the horizon, with as little energy as possible scattered towards the ground or the sky. This design, combined with the low power of PCS facilities, generally results in no possibility for exposure to approach Maximum Permissible Exposure (MPE) levels, with the exception of areas directly in front of the antennas. 3.0 AT&T RF EXPOSURE POLICY REQUIREMENTS AT&T's RF Exposure Policy guidance, dated March 31, 2009, requires that: I. All sites must be -analyzed for RF exposure compliance; 2. All sites must have that analysis documented; and EBI 21 B Street 4 Burlington, MA 01803 m 1.800.786.2340 5 RF-EME Compliance Report USiD No. 85230 Site No. CNU3657 EBI Project No. 62102044 Arastradero Rd E of 1-280, Los Altos Hills, California 3. All sites must have any necessary signage and barriers installed. Pursuant to this guidance, an RF site survey has been completed for this site. The results of the site survey are summarized below in Section 6.0 and in Appendices B, F, G, and H. Worst-case predictive modeling was also performed for the site: This modeling is described below in Section 4.0. Lastly, based on the modeling and survey data, EBI has produced a Compliance Plan for this site that outlines the recommended signage and barriers. The recommended Compliance Plan for this site is described in Section 5.0. 4.0 WORST-CASE', PREDOCTIVE MODELING In accordance with AT&T's RF Exposure policy, EBI performed theoretical modeling using RoofView® software to estimate the worst-case power density at the site ground -level resulting from operation of the antennas. RoofView® is a widely -used predictive modeling program that has been developed by Richard Tell Associates to predict both near field and far field RF power density values for roof -top and tower telecommunications sites produced by vertical collinear antennas that are typically used in the cellular, PCS, paging and other communications services. The models utilize several operational specifications for different types of antennas to produce a plot of spatially -averaged power densities that can be expressed as a percentage of the applicable exposure limit. For this report, EBI utilized antenna and power data provided by AT&T, and compared the resultant worst-case MPE levels to the FCC's occupational/controlled exposure limits outlined in OET Bulletin 65. The assumptions used in the modeling are based upon collected during the site survey andinformation provided by AT&T, and information gathered from other sources. At the time of the site visit there were no other carriers observed on the monotree. Measurements were taken at ground level to record ambient RF-EME levels of other potential antennas that might be present, though unobserved, in the vicinity. These results were added to the predictive modeling results for the AT&T antennas to calculate the cumulative worst-case MPE levels for the site after installation of the proposed AT&T equipment. Based on worst-case predictive modeling, there are no modeled or monitored areas on any accessible ground -level walking/working surface related to the proposed AT&T antennas that exceed the FCC's occupational or general public exposure limits at this site. At the nearest walking/working surfaces to the AT&T antennas, the maximum power density generated bytherY�rase""It�'i'e'd � ao> cam;a? tltkirit (0.62 percent of the FCC's occupational limit). The composite exposure level from all carriers on this site is approximately 12.56 percent of the FCC's general public limit (2.51 percent of the FCC's occupational limit) at the nearest walking/working surface to each antenna (i.e., the ground). This composite level was calculated by adding the maximum spatially, averaged reading from the site survey to the maximum predicted power density at ground level from the predictive modeling. This is an overestimation because both the modeling and monitoring include AT&T's existing antennas. The inputs used in the modeling are summarized in the RoofView® export file presented in Appendix C. A graphical representation of the RoofView® modeling results is presented in Appendix D. It should be noted that RoofView is not suitable for modeling microwave dish antennas; however, these units are designed for point-to-point operations at the elevations of the installed equipment rather than ground level coverage.

Plan presented in Appendix E. 6.0 SITE AND VICINITY SURVEY EBI performed a ground level RF -ENE survey on April 24, 2011 . The antenna inventory (based upon the site survey) and site photos taken from ground level are presented in Appendices F and G, respectively. Monitoring was performed using a Narda NBM550 Electromagnetic Radiation Survey Meter, Serial #B- 1124 with a Narda EA5091 Shaped Probe with a frequency range of 300kHz-50 GHz. The meter was last calibrated on September 3, 2010. This meter was programmed to measure the total power density for all electromagnetic radiation within the 300kHz-50GHz frequency range and report the power density as a percent of the FCC's controlled MPE. During this survey, no spatially averaged readings above 1.8920% of the FCC's occupational MPE (9.4600% of the general public MPE).were encountered on any ground surface. A site plan depicting monitoring locations and measurements of power density can be found in Appendix G. Appendix H contains notes from the site survey. At the time of the site survey, it was noted that there were three yellow "Caution" signs located on the access gate, the equipment and the base of the tower; and a green "INFO I" sign on the access gate indicating the presence of RF emitting equipment at the site. As described in Section 5.0, additional signage is recommended in order to comply with AT&T guidance. 7.0 SUMMARY AND CONCLUSIONS EBI has prepared this Radiofrequency Emissions Compliance Report for the proposed AT&T telecommunications equipment at the site located at Arastradero Rd E of 1-280 in Los Altos Hills, California.- EBI alifornia: EBI has conducted theoretical modeling to estimate the worst-case power density from AT&T antennas to document potential.MPE levels at this location and ensure that site control measures are adequate to meet FCC and OSHA requirements, as well as AT&T's corporate RF safety policies.

Attachment A is a map of all existing sites in the Town of Los Altos Hills. The existing sites are identified by yellow pincushicns. The nearest new proposed sites is south of the City in the general vicinity of the intersection of Highway 280 at Mora Drive and Highway 280 at Magdalena Avenue. In addition, because of the rapid pace that the wireless technology is evolving it is difficult to provide an accurate Antenna Master Plan. Furthermore, there are numerous other variables that effect the planning of the ATT wireless network. With that being said ATT Mobility will be proposing to modify the following facilities this year 27299 Ascension Drive and 26379 West Freemont Blvd. The modifications will be similar in scope of what is being proposed with this application. These modifications will upgrade the network in this area to provide Long Term Evolution (LTE) technology. In simple terms, LTE technology is the next generation of wireless network which will provide significantly faster data to mobile devises. 3140 Gold Camp Drive, Suite 30 Rancho Cordova, CA 95670 GSM ID I U51D I FA CODE I Description - ; 'Address Line 1 ' Town Or City Zip . lat/long '; „ Status Structure type 10095849', LOS ALTOS 280 SECOND STREET 1-280/CROOKED 94022 LONG -122.11694 on air LAT 37.3419 LONG - 1721 WHITHAM CN4019 10147301 CREEK TBD LOS ALTOS 94022 122.092 proposed site 94024 37.3475/-122.09944 ion air 1-280/LOS ALTOS 1416 CRISTO REY LOS ALTOS LAT 37.35 LONG - SF0416 13268 CN4023 DRIVE 10147303.GOLF CLUB TBD HILLS 94022 122.104 proposed site 12345 EL MONTE LAT 37.36306 LONG - PURISSIMA HILLS 13283 10095825' COLLEGE ROAD LOS ALTOS 94022122.125 on air CN3657 85230 100674751WATER ARASTRADERO ROAD LOS ALTOS 94022 37.3871/-122.15303 on air MONOPOLE 10095736,280 2350 PAGE MILL ROAD I-280 & ROBLEDA 94022 37.39/-122.1625 :on air LAT: 37.365556 LONG:' !AWE - FOOTHILL 26451 ASCENSION CN3659 51771 10067476 ROAD 26410 DUVAL WAY LOS ALTOS 94022 -122.135556 on air MONO PINE AWE - LOS ALTOS 27400 PURISSIMA LAT 37.37556 SF1820 24186 SF0095 13246 10095750 HILLS ROAD LOS ALTOS 94022 LONG -122.14528 on air MONOPOLE COLOCATE MONOPOLE COLOCATE BLDG COLOCATE MONOPOLE MONOPOLE MONOPOLE COLOCATE BLDG UTILITY POLE UTILITY POLE AWE - DOWNTOWN LAT 37.3775 SF0131 13254 10095849', LOS ALTOS 280 SECOND STREET LOS ALTOS 94022 LONG -122.11694 on air 1721 WHITHAM 'SF0410 13265 10095751!AWE - LOS ALTOS II AVENUE LOS ALTOS 94024 37.3475/-122.09944 ion air 1416 CRISTO REY SF0416 13268 10095752 AWE - LOS ALTOS III DRIVE LOS ALTOS 94024 37.3325/-122.07389 !on air AWE - FOOTHILL 12345 EL MONTE LAT 37.36306 LONG - SF0479 13283 10095825' COLLEGE ROAD LOS ALTOS 94022122.125 on air 'AWE - PAGE MILL SF0525 13291 10095736,280 2350 PAGE MILL ROAD LOS ALTOS 94022 37.39/-122.1625 :on air !AWE - FOOTHILL 26451 ASCENSION LAT 37.38028 LONG - SF1811 24152 10095826' EXPRESSWAY DRIVE LOS ALTOS 94022 122.13111 on air AWE -1280 / 380 MAGDALENA LAT 37.51083 LONG - ' SF1820 24186 10093975 MAGDALENA AVENUE LOS ALTOS 94024 121.97389 on air LOS ALTOS HILLS 26379 WEST FREMONT SF2365 80685 10100717 TOWN HALL BOULEVARD LOS ALTOS 94022 37.38432 /-122.13887 on air FOOTHILL AWE -FOOTHILL AND EXPRESSWAY AND LAT 37.35944 LONG SFE012 13350 10097002 SPRINGER MAGDALENA AVENUE LOS ALTOS 94024 122.09472 on air 'AWE - FOOTHILL AND SFE016 13351 10097003 GRANT 2055 GRANT ROAD LOS ALTOS 94024 37.34194/-122.07194 on air INTERSECTION OF GRANTAND CN3707 85283 10067430 PG&E PORTLAND ROAD LOS ALTOS 9402437.36007 / -122.07773 on air EL MONTE ROAD & LAT: 37.3644 LONG: - CN3665 109695 10067434 SUMMERHILL 1040 BORDER ROAD LOS ALTOS 94024 122.10443 proposed site AT&T Proprietary (Internal Use Only) Not for use or disclosure outside the AT&T companies except under written agreement COLOCATE MONOPOLE COLOCATE BLDG COLOCATE MONOPOLE MONOPOLE MONOPOLE COLOCATE BLDG UTILITY POLE UTILITY POLE Attachment 7 TOWN OF LOS ALTOS HILLSI,osALTosll�W_ 26379 Fremont Road Los Altos Hills, CA 94022 Phone: (650) 941-7222 a www.losaltoshills.ca.gov CAL I FO Rei IA Wireless Communications Facilities Policy Amended 10/12/2006 Code Sections Section 10-1.703 (h)(2) of the Zoning Ordinance allows service uses, including "communications facilities", to be permitted in the Town if a Conditional Use Permit is granted by the Planning Commission and City Council. Section 10-1.1007 (1) of the Code outlines findings which must be made to approve a use permit, including the proper location of the use or facility relative to others in the vicinity, the adequacy of the site to accommodate the use, and that the facility or use will not have an adverse effect on adjacent properties. Intent: The purpose of this policy is to outline the desired criteria for siting of wireless communications facilities, generally including monopoles, related antennas, and equipment shelters. As the Town's land use is virtually entirely residential, wireless communications facilities will be most appropriately located on public or institutional sites existing within the Town. Colocation, location on or near existing buildings, and landscape screening will be desired to minimize the visual impacts of the facilities on neighbors and the public. Policv: I. Priorities for siting - Wireless communication facilities shall generally be located on properties with priority as follows: a. Town -owned properties b. Foothill College c. Water tanks d. Other public or quasi -public facilities, such as schools or churches e. Residential properties of at least ten (10) acres 2. Siting on residential parcels - Wireless communication facilities may be permitted on properties used for residential purposes or vacant parcels intended for residential property owner provides written consent and significant visual impacts are mitigated. 3. Colocation — Colocation of wireless communication facilities with other facilities is encouraged to the maximum extend feasible, as long as the colocation is technologically compatible and does not substantially increase visual impacts. The Town will generally require as a condition of approval for any conditional use permit that the applicant permit colocation of other facilities, subject to technological constraints and Town review. Policy: Wireless Communication Facilities Page 2 3a. Applications for colocation on an existing wireless communications facility shall be subject to an administrative review provided that the following requirement is met: The colocated antennas and ground equipment shall be mounted or installed within an existing tower, building, or structure where the physical appearance of the existing facility is not altered to accommodate the additional antennas and equipment. 4. Landscape screening and color - Landscape screening shall be required by the Town to minimize the visual impacts of wireless communication facilities. Poles, antennas, and equipment buildings should be painted to blend with the surrounding environment and/or buildings to further minimize visual impacts. 5. Environmental review - A Negative Declaration will typically be prepared for review of proposed wireless communication facilities, with special attention to the visual impacts of the facilities. Categorical exemptions may be used where facilities are colocated with or would be minimal additions to existing structures, with negligible additional visual impact. 6. Antenna master plans — Any applicant for a wireless communication facility site shall submit applications, to the best of their knowledge, for all sites anticipated to be required by the carrier for a three (3) to five (5) year period, and the request shall be reviewed by the Planning Commission and the City Council as a master plan application. 7. Terms of permits and abandonment of sites — Conditional use permits for wireless communications facilities shall be established for periods not to exceed five (5) years, at which time renewal of the permit must be requested by the applicant. More frequent review of the operation of the permit may be made a condition of approval. Approval will also require a written agreement from the applicant that, should the use be discontinued by the carrier, all facilities will be removed not later then ninety (90) days after discontinuance of the use or abandonment. Such a provision shall also be included in any lease with the Town for use of Town lands for wireless communications facilities. The Town may require bonding or other surety to assure the removal of such facilities. 8. Wireless communication firms shall, at the time of application for permits, demonstrate efforts which have been mad to inform neighboring residents of the proposed facilities, such as conducting meetings, or mailing fact sheets and/or letters, etc...to neighbors. 9. The Planning Director is authorized to reduce or waive permit fees for any wireless communications facility that is proven to expand wireless coverage in the Town and is structurally capable of colocation. 10. The Planning Director is authorized to administratively approve portable wireless communications facilities also known as cell on wheels or COWS on certain properties as specified in Policy 91 on a temporary basis.
