1. Introduction
Figure 1-1
The electromagnetic spectrum includes various forms of electromagnetic energy from extremely low frequency energy, with very long wavelengths, to x-rays and gamma rays, which have very high frequencies and short wavelengths. In between are radio waves, microwaves, infrared, visible light and ultraviolet, for example.

As depicted in Figure 2-1, the frequencies from T-Mobile’s equipment emit non-ionizing energy. The effects of nonionizing energy are non-cumulative. Non-ionizing energy can turn into heat, if absorbed. (By comparison, ionizing energy is generally cumulative and can cause chemical and biological changes.) (FCC OET Bulletin 56, Fourth Ed.)

RF emission levels were assessed through direct measurements at the transmitter site using properly calibrated field probes. Due to the possibility that Electromagnetic Energy (“EME”) fields may exist over a wide frequency range within which the exposure limits vary, field measurements were performed with a meter equipped with a frequency shaped probe that can automatically weigh each field contribution in accordance with its frequency.

Exposure
The FCC guidelines for human exposure to RF emissions were derived from the recommendations of two expert organizations, the National Council on Radiation Protection and Measurements (“NCRP”) and the Institute of Electrical and Electronics Engineers (“IEEE”). The exposure guidelines are based on thresholds for known adverse effects and they incorporate an appropriate margin of safety. The federal health and safety agencies such as the Environmental Protection Agency (“EPA”), the Food and Drug Administration (“FDA”), the National Institute on Occupational Safety and Health (“NIOSH”) and the Occupational Safety and Health Administration (“OSHA”) have also been actively involved in monitoring and investigating issues related to RF exposure.

The FCC’s Maximum Permissible Exposure (“MPE”) limits are based on exposure limits (over a wide range of frequencies) recommended by the NCRP and the exposure limits developed by the IEEE and adopted by the American National Standards Institute (“ANSI”). The limits for localized absorption are based on the recommendations of both the ANSI/IEEE and the NCRP. The potential hazard associated with the RF electromagnetic fields is discussed in OET Bulletin No. 56 “Question and Answer about the Biological Effects and Potential Hazards of Radiofrequency Electromagnetic Fields.” This document can be obtained on the FCC website at www.fcc.gov. The table and the graph below represent the FCC limits for both occupational and general population exposures to different radio frequencies:

7. Discussion of Safety Criteria
Energy levels associated with the RF radiations are not great enough to cause the ionization of atoms and molecules. “Ionization” is a process by which electrons are stripped from atoms and molecules. This process can produce molecular changes that can lead to damage in biological tissue including effects on DNA, the genetic material. This process requires interaction with high levels of electromagnetic energy. Those types of electromagnetic radiation with enough energy to ionize biological material include x-radiation and gamma radiation. Therefore, x-rays and gamma rays are examples of ionizing radiation (see Section 1 for additional information).

RF energy is a type of non-ionizing radiation. Other types of non-ionizing radiation include visible light, infrared radiation and other forms of electromagnetic radiation with relatively low frequencies. Often the term “radiation” is used to apply to ionizing radiation associated with nuclear power plants. Ionizing radiation should not be confused with the lower energy, non-ionizing radiation with respect to possible biological effects.

The RF emissions from antennas used for wireless telecommunications typically result in exposure levels at the site that are well below the limits recommended by the FCC. These limits were adopted by the FCC based on the recommendations of expert organizations and endorsed by agencies of the Federal Government responsible for health and safety. Therefore, there is little reason to believe that such antennas could pose a potential health hazard to the general population.

Other antennas, such as those used for radio and television broadcast transmissions, use power levels that are generally higher than those used for wireless antennas. Therefore, in some cases, there could be a potential for higher levels of exposure on the site. However, all broadcast stations are also required to demonstrate compliance with the FCC guidelines.

8-1 Ground Level Readings
Below is the layout depicting the actual readings (% of the FCC MPE Occupational or General Population Standard limits) at various locations at the site. Various measurements were taken to indicate the RF emissions levels that can be encountered by an individual who gains access to the area of interest involved with the survey.

A RF emissions survey was performed on the wireless telecommunications facility. This survey included walking around the structure and noting the maximum max hold readings encountered. The maximum value of the max hold readings of RF emissions encountered on the ground level was: 0.98% of the occupational standard or (4.9% of general population standard).

A controlled/occupational environment assumes that access to the facility is generally restricted to authorized personnel and facility management and members of the general population will not be able to access the rooftop and/or wireless telecommunications facility.

This report was prepared for T-Mobile and serves as certification for compliance of the existing T-Mobile wireless telecommunications facility. The analysis and computation provided herein is based on applicable FCC regulations concerning RF safety and the control of human exposure to RF emissions. The information and analysis contained in this report is accurate and complete to the best knowledge and belief of the undersigned.

Compliance with the FCC’s rules on human exposure to RF emissions at wireless telecommunications facilities generally is determined by comparing actual measurements taken at the facility to the FCC’s MPE limits.

The results of the instant survey indicate the maximum levels of RF emissions exposure do not exceed applicable FCC MPE limits for occupational and general population exposure.

The highest level of RF emissions measured was 0.98% of the FCC’s MPE limits based on the occupational exposure standard or (4.9% of general population standard).

An uncontrolled/general population environment assumes that access to the facility is not generally restricted to authorized personnel and facility management and members of the general population will be able to access the rooftop and/or wireless telecommunication facility.

This facility's Area of Interest is considered a controlled (occupational population) environment. The site is in compliance with FCC limits and guidelines per MPE standard for the environment. 12/02/2025

Statement of Hammett & Edison, Inc., Consulting Engineers The firm of Hammett & Edison, Inc., Consulting Engineers, has been retained by T-Mobile West LLC, a personal wireless telecommunications carrier, to evaluate proposed modifications to its existing base station (Site No. SF04627A) located at 26140 Duval Way in Los Altos Hills, California, for compliance with appropriate guidelines limiting human exposure to radio frequency (“RF”) electromagnetic fields.

Executive Summary
T-Mobile proposes to replace its directional panel antennas within the steeple above the roof of the church located at 26140 Duval Way in Los Altos Hills. The proposed operation will comply with the FCC guidelines limiting public exposure to RF energy; certain mitigation measures are recommended to comply with FCC occupational guidelines.

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

C-Band 3,700 MHz 1.0 5.0
CBRS (Citizens Broadband Radio) 3,550 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

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 passive 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 T-Mobile, including construction drawings by SureSite Consulting Group, LLC, dated January 20, 2022, that carrier presently has directional panel antennas installed within the steeple above the entrance to the sanctuary at St. Luke’s Chapel in the Hills, located at 26140 Duval Way in Los Altos Hills. T-Mobile proposes to replace those antennas with six directional panel antennas – three each RFS Model APXVAALL24_43-U-NA-20 and Ericsson Model AIR6449 – at the same locations. The RFS antennas would be mounted at an effective height of about 37 feet above ground, 9½ feet above the roof, and would employ 2° downtilt. The Ericsson antennas would be mounted at an effective height of about 44 feet above ground, 16½ feet above the roof, and would employ up to 11° downtilt. The antennas would be oriented in identical pairs toward 100°T, 220°T, and 340°T, to provide service in all directions. The maximum effective radiated power in any direction would be 91,410 watts, representing simultaneous operation at

59,310 watts for BRS,* 13,920 watts for AWS, 9,570 watts for PCS, 3,540 watts for 700 MHz, and 5,070 watts for 600 MHz service. 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 is calculated to be 0.18 mW/cm2, which is 20% of the applicable public exposure limit.

The maximum calculated level at the nearest building† is 16% of the public exposure limit. The maximum calculated level at the second-floor elevation of any nearby residence‡ is 37% 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. Levels may exceed the applicable public exposure limit on the roof of the subject building and at heights above 26 feet above ground on the tree on the west side of the building, and levels are calculated to exceed the applicable occupational exposure limit on the roof of the building entrance, as shown in Figure 3.

Recommended Mitigation Measures
Due to their mounting locations 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. To prevent occupational exposures in excess of the FCC guidelines, it is recommended that appropriate RF safety training, to include review of personal monitor use, review of lockout/tagout procedures, and review of the information in Figure 3, be provided to all authorized personnel who have access to the blue- and yellow-shaded area, including employees and contractors of T-Mobile and of the property owner. No access within 55 feet directly in front of the T-Mobile antennas themselves, such as might occur during certain maintenance activities on the steeple, should be allowed while the base station is in operation, unless other measures can be demonstrated to ensure that occupational protection requirements are met. It is recommended that explanatory signs§ be posted at the base of the steeple, readily visible from any angle of approach to persons who might need to work within that distance. It is recommended that T-Mobile coordinate with the church to arrange for shut-down of the 220°T and 340°T antenna groups if work is needed at height on the adjacent tree. * The manufacturer reports that the antenna transmits 75% of the time in this band; this factor is incorporated into the calculations. † On the church property, about 60 feet away. ‡ Located at least 80 feet away, based on photographs from Google Maps. § Signs should comply with OET-65 color, symbol, and content recommendations. Contact information should be provided (e.g., a telephone number) to arrange for access to restricted areas. The selection of language(s) is not an engineering matter, and guidance from the landlord, local zoning or health authority, or appropriate professionals may be required.

Conclusion
Based on the information and analysis above, it is the undersigned’s professional opinion that the proposed operation of the T-Mobile West LLC base station located at 26140 Duval Way in Los Altos Hills, 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. Training authorized personnel and posting explanatory signs are recommended to establish compliance with FCC guidelines.

The U.S. Congress required (1996 Telecom Act) the Federal Communications Commission (“FCC”) to adopt a nationwide human exposure standard to ensure that its licensees do not, cumulatively, have a significant impact on the environment. 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 and approved as American National Standard ANSI/IEEE C95.1-2006, “Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz,” includes similar limits. These limits apply for continuous exposures from all sources and are intended to provide a prudent margin of safety for all persons, regardless of age, gender, size, or health.

As shown in the table and chart below, separate limits apply for occupational and public exposure conditions, with the latter limits (in italics and/or dashed) up to five times more restrictive:

Hammett & Edison has incorporated the FCC Office of Engineering and Technology Bulletin No. 65 (“OET-65”) formulas (see Figure 1) in a computer program that calculates, at millions of locations on a grid, the total expected power density from any number of individual radio frequency sources. 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 timeaveraging 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:
power density in mW/cm2
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”:
power density in mW/cm2 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.

Staff Report to the City Council
SUBJECT: DISCUSSION AND DIRECTION REGARDING A POTENTIAL

WESTWIND COMMUNITY BARN MAINTENANCE AND

IMPROVEMENT MASTER PLAN
FROM: Joram Parcutilo, Management Analyst
APPROVED: Cody Einfalt, City Manager
RECOMMENDATION: That the City Council should provide direction to staff regarding whether to:

1. Continue the existing case-by-case maintenance and capital improvement approach for Westwind Community Barn; or

2. Direct staff to explore development of a long-term Westwind Community Barn Master Plan and return to City Council with a proposed scope of work, project schedule, and funding strategy.

No formal action or resolution is required at this meeting.

BACKGROUND:

Westwind Community Barn is one of the Town's most unique and recognizable community assets.

Located on approximately 15 acres, the facility serves as a longstanding equestrian resource for residents and visitors and represents an important part of the Town's rural character, equestrian heritage, and community identity.

The facility is currently operated by Victoria Dye Equestrian (VDE) pursuant to an operating agreement approved by the City Council. As an aging facility, many of its buildings, paddocks, retaining walls, fencing, and supporting infrastructure require ongoing maintenance and periodic capital investment to remain safe, functional, and attractive for users.

Historically, improvements and maintenance at Westwind Community Barn have been addressed on a case-by-case basis. Under the current approach, VDE identifies maintenance concerns or facility needs and submits requests to Town staff. Staff then evaluates the request, coordinates with the Public Works Maintenance Division, and determines whether the issue can be addressed through routine maintenance operations, available capital funding, or future budget requests.

As part of the recently approved renewal agreement with Victoria Dye Equestrian (VDE), the Town and VDE discussed the long-term maintenance and capital needs of the facility. Recognizing the age of the facility and the importance of preserving the Barn for future generations, the renewed agreement formally established a dedicated annual Capital Improvement Program (CIP) funding target of approximately $50,000 to $100,000 for Westwind Community Barn improvements. The purpose of this funding commitment is to provide a mechanism for addressing larger facility ITEM 8A

improvements and capital needs that extend beyond routine maintenance activities. Town Staff and Torie also did a walkthrough of the facility to see the current status of the facility and prioritize a list that determines the immediate and future needs of Westwind Barn.

The resulting list identified a variety of needs throughout the facility, including replacement of deteriorated barn doors, repairs to retaining walls within multiple paddocks, fencing improvements, safety upgrades, structural concerns around portions of the barn, shelter improvements, and enhancements to tack-up and cross-tie areas. These discussions highlighted the need to consider whether future investments should continue to be addressed individually or through a more comprehensive long-term planning framework.

Staff reviewed the list of identified maintenance and capital improvement needs. As part of this review, staff conducted an initial assessment to distinguish between projects that may be addressed through existing Public Works maintenance resources and projects that would likely require future Capital Improvement Program (CIP) funding. This exercise was intended to provide a preliminary framework for prioritizing repairs and understanding the magnitude of future investment needs at the facility.

Maintaining Westwind Community Barn in the best condition possible remains an important objective for the Town. In addition to preserving a valuable public asset, continued investment in the facility helps support one of the Town's keystone community resources and preserves an important component of Los Altos Hills' equestrian heritage.

DISCUSSION:

Existing Approach
The Town currently addresses Westwind Community Barn improvements on an as-needed basis.

Under this approach:
• Torie identifies facility needs and maintenance concerns; • Town staff evaluates requests and priorities;
• Public Works Maintenance staff addresses repairs when feasible; and • Larger capital projects are considered through the annual budget and Capital Improvement Program (CIP) process.

This approach has provided flexibility and allows staff to address immediate concerns as they arise. However, it does not establish a long-term vision for the facility or provide a framework for prioritizing future improvements.

While the current process has generally been successful in maintaining operations at the Barn, projects are often evaluated independently rather than as part of a broader strategy for preserving and improving the facility over time.

3 Staff Report to City Council
Westwind Barn Masterplan Discussion
June 18, 2026
Preliminary Maintenance and Capital Improvement Assessment As part of the ongoing evaluation of Westwind Community Barn, staff reviewed the list of facility needs identified during the site walkthrough. Staff's preliminary assessment categorized projects into two groups: (1) items that may be completed utilizing existing Public Works maintenance resources and available contract maintenance hours, and (2) items that would likely require future CIP funding due to their scope, complexity, or cost.

Potential Maintenance Projects (Existing Resources)
The following items were identified as projects that may be completed through existing maintenance resources:
• Removal of an abandoned shed with rodent activity;
• Repair and grading of erosion near the shed at the bottom of the hill; and • General pasture cleanup and maintenance.

Potential Capital Improvement Projects (Future CIP Funding) The following items were identified as projects that would likely require future capital funding:
• Rehabilitation of approximately ten paddocks (estimated at approximately $250,000); • Replacement of four deteriorated barn doors;
• Replacement of seventeen stall doors;
• Concrete repair and weatherproofing beneath barn windows (estimated at approximately $12,000);
• Construction of an expanded feeding pasture shelter;
• Installation of a more substantial handrail within the hay loft; • Removal of obsolete security wiring within the hay loft; and • Replacement of fencing surrounding the grass area (materials estimated between $15,000 and $20,000, with installation potentially performed by Town staff).

Based upon current budget projections, staff estimates that the approximately $75,000 currently identified for Westwind Community Barn improvements in the upcoming fiscal year would only be sufficient to address a limited number of these capital projects.

This preliminary assessment illustrates the growing list of maintenance and capital improvement needs throughout the facility and highlights the challenge of prioritizing investments under the current case-by-case approach.

Potential Master Plan Approach
During discussions with Torie, both staff and Torie acknowledged that neither party possesses the specialized institutional knowledge necessary to develop a comprehensive equestrian facility plan based upon industry best practices.

4 Staff Report to City Council
Westwind Barn Masterplan Discussion
June 18, 2026
One option for Council consideration would be the development of a Westwind Community Barn Master Plan.

A master plan is a long-range planning document that evaluates the existing condition of a facility, identifies current and future operational needs, prioritizes improvements, and establishes a phased strategy for implementation over time. Rather than addressing projects individually as issues arise, a master plan provides a comprehensive framework for decision-making and helps ensure that future investments are coordinated, strategic, and aligned with the long-term vision for a facility.

A Master Plan could evaluate:
• Existing facility conditions;
• Barn rehabilitation and replacement priorities;
• Arena improvements and maintenance strategies;
• Paddock, retaining wall, and fencing improvements;
• Safety and accessibility enhancements;
• Operational needs;
• Parking improvements;
• Capital improvement prioritization; and
• Long-term implementation strategies and cost estimates.

A Master Plan would provide a roadmap for future maintenance and capital investment decisions and could assist the Town in establishing priorities for future improvements over a multi-year horizon.

The Town recently completed a similar planning effort through the Corporation Yard Master Plan in 2024 (Attachment 1). That study included a comprehensive assessment of existing facilities, evaluation of operational and space needs, identification of deficiencies, and development of prioritized recommendations for future maintenance and capital improvements.

The resulting Master Plan provided the Town with a long-term planning document that helps guide budgeting, maintenance planning, and future capital investments at the Corporation Yard.

Similar planning efforts have been undertaken by other jurisdictions for public equestrian facilities as well as by the Town through the Corporation Yard Master Plan, which evaluated existing conditions, identified operational needs, and established future capital improvement priorities.

ANALYSIS:

Staff's recent review of facility conditions demonstrates that the cumulative cost of identified improvements substantially exceeds currently available funding levels. While certain maintenance items can be addressed through existing Public Works resources, many of the larger facility needs—including paddock rehabilitation, barn improvements, fencing replacement, and safety upgrades—will require significant future capital investment. As these needs continue to grow, the

Town may benefit from a comprehensive planning document that establishes priorities, identifies funding strategies, and provides a phased implementation schedule.

A Westwind Community Barn Master Plan could serve a similar function to the Corporation Yard Master Plan by providing a structured framework for evaluating facility conditions, identifying long-term operational needs, and guiding future capital investment decisions. Such a plan could also assist the Town in determining which projects should be prioritized in the near term versus deferred to future budget cycles.

Westwind Community Barn remains an important community asset and a significant component of the Town's rural and equestrian character. As the facility continues to age, maintenance and capital needs will likely continue to emerge.

Development of a Westwind Community Barn Master Plan is not currently identified within the City Council Work Plan.

Should Council direct staff to pursue a Master Plan, staff would need to evaluate resource impacts and determine how the project would fit within existing departmental priorities and current Work Plan commitments. Moving forward would require a shift in staff resources and prioritization of work efforts to accommodate consultant procurement, stakeholder outreach, project management, and City Council review.

As a result, staff is seeking policy direction from the City Council regarding whether the Town should continue the current case-by-case approach or pursue a comprehensive long-term planning effort.

ENVIRONMENTAL REVIEW:

The proposed project does not qualify as a “Project” as defined in California Government Code Section 15378(b) of the California Environmental Quality Act (CEQA).

FISCAL IMPACT:

While there is no immediate fiscal impact associated with receiving this report and providing direction, staff's preliminary assessment identified several potential capital projects at Westwind Community Barn whose combined costs exceed currently available CIP funding levels.

Additional funding requests may be necessary in future budget cycles depending on Council direction and project prioritization
Should the City Council direct staff to pursue a Westwind Community Barn Master Plan, staff estimates consultant costs could range from approximately $60,000 to $130,000 depending upon the scope of work. In 2024, when staff contracted the KPA Group to put together the Corporation Yard Master Plan, staff budgeted $50,000 for the study.

CORPORATION YARD MASTER PLAN 4
I. Executive Summary

EXECUTIVE SUMMARY
In February 2024, the Town of Los Altos Hills retained the KPA Group to prioritize future improvements to the Corporation Yard as part of the the Corporation Yard Master Plan. KPA developed program requirements for Public Works, prioritized recommended improvements over a 10-year period and analyzed the conditions of the existing Corporation Yard site and building. Proposed improvements to the Corporation Yard address current operational ineffi ciencies and existing site constraints.

General Background
The Town of Los Altos Hills is home to over 8,100 residents among

9.03 square miles. The services provided at Town Hall include administrative functions and services while the Corporation Yard supports maintenance and repair work. Planning eff orts completed as part of this Master Plan focus on recommendations and improvements for the Corporation Yard site only.

The Los Altos Hills Corporation Yard is located at 27400 Purissima Road adjacent to the 280 freeway. The site encompasses
approximately 13,500 square feet of area and contains a two-story facility designed and constructed in 1979. The site is bound by Purissima Road to the Northeast, Purissima Park to the Southeast, the 280 freeway to the Southwest and an adjacent trail parking lot to the Northwest.

Additional Site Elements and Structures Include:
• Two-story facility of approximately 5,000 SF housing
maintenance equipment, vehicles, tools, storage and offi ce spaces
• Entrance gates provided at Purissima Road – One powered gate, one manual gate
• Exterior covered unenclosed structure providing
approximately 1,400 SF of protected storage
• Fueling station for diesel refueling
• Material lay down and containment areas
• Perimeter fencing
• Bioswale areas
• Asphalt pavement throughout site
No signifi cant future program changes to Public Works or the Corporation Yard site are anticipated in the foreseeable future.

Recommendations and analysis contained within this master plan shall be revisited and adjusted to align with future Town and Corporation Yard goals.

Existing Conditions
The Corporation Yard has had minor updates to the facility and site occuring since original construction. In 2012, a seismic retrofi t of the facility was performed. Noted site changes include new asphalt pavement, perimeter fencing and material laydown areas. Critical defi ciencies are as follows:
• Garage doors are damaged/non-functional
• Wood windows are deteriorating and exhibiting rot
• Wood siding is rotting at base
• Interior restrooms require accessibility improements
• Lack of locker room
• No centralized HVAC system in place
• Lack of exit signage
Capital Improvement Plan (CIP)
The underlying goals of the Corporation Yard Master Plan are to assess existing site and building defi ciencies, confi rm Public Works space requirements and prepare viable capital improvement projects to plan for future changes to the Corporation Yard.

This report provides various Capital Improvement projects recommended to be completed by the Town over the future 10 years and beyond. Construction of recommended improvement projects will provide the Corporation Yard with modernized work spaces and site attributes to address some of the current work ineffi ciencies observed as part of the master planning process.

Also included in recommendations are Asset Management projects, which are specifi c projects identifi ed to maintain and improve existing conditions without performing extensive building or site modifi cations. These projects may be supplemental Capital Improvement projects during construction or be considered as seperate maintenance items.

The location of the current Corporation Yard facility as a self-suffi cient facility and separate from Town Hall is preferred by Public Works Department maintenance staff .

KPA proposes Capital Improvement and Maintenance Projects to be completed over the course of 10 years. Proposed projects are categorized and prioritized as Years 1-2 projects, Years 3-5 projects, Years 6-10 projects and Proposed Future Projects (beyond 10 years). Proposed improvement years take into account current planned improvements projects at the interior of the facility and defi ne recommendations for other necessary improvements that would benefi t the overall Corporation Yard within the next 10 years.

Proposed future projects include considerations that, if funded, may provide the Town and facility with additional improvements to continue to meet the Town’s maintenance needs beyond the next 10 years. Sign Storage

I. Executive Summary
Capital Expenditure
The Corporation Yard Master Plan provides estimated costs for projects to maintain existing assets (Asset Maintenance Projects) and for new construction projects (Capital Improvement Projects). Asset Maintenance Projects are defi ned as projects working to maintain or replace existing building and site assets. Capital Improvement Projects are defi ned as projects working to improve existing conditions with new construction changes.

Total capital expenditure in 2024 dollars recommended within the future 10 years was estimated for Asset Maintenance Projects and for Capital Improvement Projects.

Asset Maintenance Projects are estimated at $839,500 in 2024 construction dollars. Estimated costs are either related to replacing existing assets beyond their useful service life or for continuing to maintain specifi c aspects of the Corporation Yard site.

Capital Improvement Project costs for all proposed projects are estimated at $2,929,625 in 2024 construction dollars including potential future projects. Costs for projects recommended to be completed within the future 10 years make up approximately 70% of total estimated capital expenditure ($2,067,125 in 2024 construction dollars).

Additional costs will be realized due to infl ation in the economy. Utilizing an estimated infl ation rate of 3.8% per year, total Capital Expenditure costs of $2,929,625 in 2024 construction dollars are predicted to be equivalent to $4,098,153 after 10 years, should no work be completed during this time. The reality of increased construction costs due to infl ation will place additional fi nancial burden on the Town should funding of recommended improvements be postponed.

CONDITION SUMMARY
Facility Condition
Site 3.3
A large stormwater drain leads from the adjacent Interstate 280 freeway and runs under the Corporation Yard site. This drain connects to other stormwater drainage from either side of Purissima Road and to a single drain going underneath the roadway and leading to Purissima creek. Grass plantings between the front of the site and Purissima road creates spillover of mud and debris during rainy events.

A small area on the site adjacent to the southwest side of the building currently provides uncovered storage for street signage, cones and other materials. A small storage container is located in this area but does not provide enough space for all items stored at this part of the site.

Perimeter fencing is generally in good condition but some areas are wrapped around site asphalt and are bent in
these locations, especially at the west side of the site near trail lot and large material laydown bays. Most perimeter fencing is black vinyl clad with privacy slats. A portion of chain link fencing next to main entrance is standard chain link without privacy slats. This fencing is visibly in good condition. Two gates exist along Purissima road for entrance to the Corporation Yard site. The main gate is powered
with LiftMaster system and in good operable condition and the secondary gate is manually operated. Light buildup of debris is present along gate tracks and gate surface fi nish is noticeably weathered and worn and could benefi t from refi nishing. Light surface rusting is present at components of gate track system including at bolt connecting sliding track wheel to gate.

Bollards are positioned to protect Liftmaster gate operator and fl ag pole from possible collisions with Corporation Yard vehicles.

Overall Rating 2.7
Large concrete blocks were recently installed to create material lay down area at the northwest portion of the site. This space provides separate bays to store large amounts of raw material and has been reported to function well for the Town.

Bioswale areas were recently installed at the yard and provides onsite stormwater treatment. Bioswale areas connect to the drainage system underneath Purissima road and treated water is directed to fl ow into Purissima Creek.

Site asphalt contains light dirt buildup from transfer of materials but is otherwise in good condition. Asphalt was recently replaced during installation of bioswale areas.

Site curbing is in good condition and a large extent of curbing was recently installed during construction of bioswale areas.

Minimal surface deterioration is present at site curbing.

Site landscaping includes large trees present at area between Interstate 280 and the corporation yard. Additionally, there are a variety of plantings along Purissima Road at entrance gate.

Exterior Envelope 2.8
Exterior wood siding is in fair condition with minimal splits and warpage. Worse conditions occur at base of building perimeter where signs of water damage is present. This
damage is visible along southeast portion of building adjacent to Purissima Park ballfi eld. Paint is weathered and faded.

Main man door entrance contains lower quality door hardware and surface damage. Paint chipping at door edges and frame.

Roll up garage doors are dented at bottom sections and do not seal properly against the concrete fl oors which creates daylighting at threshold and allows water intrusion during rain events. Torsion springs appear to be in good condition. Doors present with heavy dirt buildup at interior horizontal portions of door surface.

Roof surface is in good general condition. Sections of roof shingles appear to have been recently replaced and some shingles are slightly out of plumb with remainder of roof surface. Moss buildup is present at certain sections of the roof, especially at northwest side of roof facing yard adjacent to the tall trees. Eaves are in good condition with minimal wood surface cracking and no visible deterioration of paint surface. Wire mesh between exterior siding and wood eave is continuous and no breakage in wire mesh were observed.

Gutter and downspout system is in good overall condition but some downspouts drain directly onto asphalt surface of site.

At southeast side of building, downspouts draining onto dirt pathway are slightly damaged and dented at bottom ends of pipes. At northwest side of building, downspout adjacent to man door entrance is also damaged. Portions of gutter system are leaking at seams where two gutter sections are connected.

Building vents at exterior siding of attic are in good condition with slats that appear to be plumb and undamaged.

Windows are dual-pane glazing but residential grade and contain heavy grime buildup on tracks and at exterior and interior sills. Some window locking mechanisms were not functioning properly and generally diffi cult to slide along tracks. Rubber gaskets surrounding glazing at windows are separating from housings at certain locations. Exterior wood window sills at second level show visible signs of heavy paint chipping. A small round skylight exists at the second level and appears to be clean and in good condition.

Site furniture includes a vinyl-clad picnic table near main entrance man door. Picnic table is in poor condition with surface staining at table top and benches and presents with heavy paint deterioration at frame components.

This is an open stairwell to second fl oor which is not compliant with the current fi re code. Stair handrails do not contain fl at elements at base or top of stair. Rubber mat at stair base has surface bubbling at edges which creates a tripping hazard.

A number of door hinges at interior doors are resuted. The non-ADA compliant shower contains grime buildup and
is undersized. Exhaust fan in restroom has excessive dust buildup. Vinyl fl oor surface is in poor condition around toilet and presents with stains and cracks.

Ceiling surface is in fair to good condition throughout the facility. Some surface paint anomalies exist and minimal surface cracking in drywall ceiling are visible in certain areas.

This occurs at second level in storage area and sign shop and is a result of light level changes throughout the building.

Walls throughout the facility appear to be deteriorating including scuffi ng at corner edges and grime buildup at baseboards.

Overall building structure is in fair condition. Foundation appears to be in good condition with no visible cracking at exposed extents. Interior cracks can be found at drywall surfaces caused by basic foundation settlement over time of the building structure. Cracks appear to have occured after the 2012 seismic retrofi t due to overall condition of the interior drywall.

Attic access is provided by ceiling hatch on second level.

Lighting fi xtures in break area do not contain lenses. Portable air conditioning units are used throughout the building including at break area. Exposed cable wiring is present at ceiling surface and at superintendents offi ce.

The majority of lighting throughout the facility consists of ceiling mounted or hanging fl uorescent tube-style fi xtures.

Most fi xtures do not contain lenses. Emergency supplies room at fi rst level contains the only light unit lens observed in the building.

Utility sink at second fl oor restroom has a cracked plastic surface in bowl leading to possible water leakage onto fl oor when in use.

The building does not have code required lighted exit signage.

Currently, paper exit signage mounted on walls throughout the facility.

The building contains electrical panels from diff erent eras including some panels thought to be original to building construction. Electrical panels are in good visual condition but some panels are blocked by equipment or tools stored in front of panels which impede access. Circuits are identifi ed at individual panels. Main 200A electrical service is housed at exterior shed adjacent to main entrance and street-facing garage doors.

Site utilities include PG&E service handhole located just east of the main entrance gate. An AT&T communications handhole exists approximately 15 feet further east from the PG&E handhole. Water service for daily use is provided at hose bib near main entrance adjacent to garage doors facing Purissima Road.

Ethernet cable runs to security cameras present under eaves and cable is exposed along underside of eaves.

Security cameras exist at building interior and site. Site security cameras are mounted adjacent to second-level sliding barn door leading directly to storage area at second level and under roof eaves at sides of building.

Water heater is located at break area and was manufactured in April 2022. Counter top surface at break area was cut to provide plumbing for water heater. Data communications
cabinet is located centrally at second level in open work area adjacent to sign storage area.

Central HVAC controls provide control for attic heater system only with controls for portable AC units provided at individual units.

A wide variety of equipment is present throughout the facility.

Most equipment is arranged in logical manner with many tools stored on wall hooks and larger equipment and vehicles stored at the fl oor areas. Wall storage system is in good condition with minimal deterioration of plywood surface and minimal damage to tool hanging holes. The Town’s maintenance
equipment and vehicles are stored at the fi rst level and take up the majority of fl oor space at the fi rst level. Some equipment is diffi cult to access because they are stored behind other large equipment.

Large equipment storage locations do not have surface
protection at concrete fl oor which causes noticeable scuffi ng of concrete surfaces. Dirt and plant material debris fallen from stored equpment is also present at fl oor surface that has fallen from equipment. Some exposed conduit and wiring is present at fi rst level garage.

Fueling is currently provided at shipping container fuel facility which houses 55 gallon diesel drums connected to copper fuel piping that is in turn connected to a fuel pump system.

Suggested Process
for
Alternate Housing Sites
Rajiv Bhateja & George Tyson
Town of Los Altos Hills
Alternate Sites ad hoc Committee
May 29, 2026

Background
● The ad hoc committee has explored several sites in town and contacted owners to gauge their interest in rezoning parcels for multi-family ○ To date the interest level has been very low, so progress has been challenging ● It is in the town’s interest to identify and rezone a few parcels to meet future housing element needs
○ Los Altos Hills will need additional multi-family housing sites for future Housing Element milestones
● A very few homeowners have expressed openness to converting their parcel to multifamily ● However, these homeowners lack the liquidity to pursue the rezoning on their own ● Question: What kind of support (if any) should the town provide in such cases?

Considerations
● If the town expends resources, there needs to be a way to (eventually) recover those costs (or receive an in-kind benefit)
○ The benefit could be that these help meet housing element needs (current or future cycles) ● Due to resource/bandwidth limits, this can be done for only a limited number of sites ● The sites must be vetted for multi-family suitability keeping in mind factors such as:
○ Terrain and size
○ Location
○ Evacuation options
○ Access
○ Fire risk
○ Sewer/utility availability
○ Traffic impact
○ Proximity to various neighborhood features
■ Freeway, school, transit corridors, SB 9s, ADUs, parks ○ [Not an exhaustive list]
● These decisions are the prerogative of the City Council ● Selection via a transparent process with ample opportunities for public input

Proposed Methodology
● Council has appointed an ad hoc committee to evaluate alternate sites ○ Currently: Rajiv Bhateja, George Tyson
● The ad hoc committee evaluates candidate sites for the factors listed previously ● Ad hoc committee shares details with the Housing Element Implementation Committee ● Ad hoc committee presents candidate sites to the full Council at a public meeting ○ Requires property owner’s consent
○ Ad hoc committee’s assessment based on identified criteria ○ Housing Element Implementation Committee provides input ● Council holds public hearings to get feedback on the site as a multi-family location

Proposed Methodology (contd.)
● If Council decides that the site is suitable, Town can proceed with rezoning process ● REZONING COST OPTIONS
● Default process is for the owner to bear costs associated with rezoning ● Council can elect to defer rezoning costs
○ Due to cost and staff bandwidth, this would apply to only a limited number of sites as determined by future housing element cycle needs and budget/resource impact ○ Town would maintain a record of associated rezoning costs ○ Rezoning costs could be recovered as part of any multi-family development or when the property is sold, whichever comes first
○ Owner would agree that if they opt out of the process, Town would recover incurred costs ■ Cost would be capped
■ Recovery could be upon sale or other “qualifying” event (e.g., permit issued) ○ Given that the Town benefits from identifying additional housing sites, Town could subsidize the rezoning - per the decision of the City Council

Guidelines for Proclamations,
Commendations and Commemorations
The basic premise when considering recognitions is that the Mayor provides direction to Staff to initiate recognition. In providing that direction, the Mayor takes into account the following guidelines in determining if the City Council wishes to consider recognition. If a Council member wishes to initiate recognition, he/she should contact the Mayor.

FORMS IN WHICH THE RECOGNITION CAN BE PREPARED:

Proclamations
Proclamations are a form of a Certificate, but with a Proclamation, something is being proclaimed. These are typically used for Fire Prevention Week, United Way Week, etc.

The Mayor should determine, at a meeting of the City Council, if the City Council is in favor of presenting the Proclamation and if they want it presented on the agenda. The Mayor will then provide direction to staff. If the recipient cannot be present at a meeting, the Proclamation will be mailed. In some instances, a Proclamation is presented at an event by the Mayor.

Proclamations are not issued for religious observances, ethnic celebrations or events that are not local or regional in nature.

Resolutions
Many cities use the “Resolution” as a means of recognizing groups or individuals. A Resolution is a formal, written action of the City Council and must be agendized for a vote. All Resolutions adopted by the City Council are numbered and placed in the official book of Resolutions. The Resolution that is presented contains the same basic wording. It will be signed by the Mayor on behalf of the Council. If a Resolution is used to provide recognition, it is only used in the most significant cases.

Adoption of a Resolution requires a staff report with a recommendation and justification for issuing the Resolution.

Certificates
Certificates are prepared in response to the type of recognition desired. These include Certificates of Commendation, Certificates of Recognition and Certificates of Appreciation.

The Mayor should determine if the City Council is in favor of presenting the Certificate and if they want it presented on agenda. The Mayor then provides direction to staff.

Presentations will not be agendized if the recipient cannot be present at the meeting to

Adopted 5/1/03
Revised February 28, 2013
3 receive the Certificate. In some instances, a Certificate is presented at an event by the Mayor.

Certificates are not issued for religious observations, ethnic celebrations or recognition that is not local or regional in nature.

Plaques
Plaques are an appropriate means of recognition for significant service to the Town.

Plaques are presented to outgoing Councilmembers and Commissioners who complete their terms of office. If a Commissioner applies and is reappointed, the recognition is given when he/she leaves the Commission. A plaque can be presented as a recognition for the outgoing Mayor.

Meeting Dedication
There are times when a meeting is dedicated to the memory of an individual. The Mayor would initiate this action. When a meeting is dedicated, a notation appears on the agenda and the Mayor announces that the meeting is in memory of an individual.

TYPES OF REQUESTS FOR RECOGNITION
The following are guidelines regarding when recognition should occur.

Community Events
There are many events that may occur in the community. The Mayor, after determining if the City Council is in favor of issuing the Proclamation or Certificate, will provide direction to staff regarding if and how the recognition should occur. In making that determination, the City Council should consider the significance of the event to the entire community.

Athletic/Academic Accomplishments
Recognition may be provided when an individual or a team reaches a significant level of competition. Recognition can be given for a local or regional Championship level. If the competitor continues to compete at the State and/or National level, recognition should be given when the individual or team has completed the highest level of competition.

Athletic accomplishments should be limited to those made by children residing in Los Altos Hills competing in school-related or publicly conducted and sanctioned competitions. Adults residing in the community may also be recognized for their athletic achievements in well-recognized sporting events.

The determination of when recognition is appropriate is the responsibility of the City Council and/or the coaches, teachers, or administrators at the school.

Adopted 5/1/03
Revised February 28, 2013
3 Acts of Heroism
Recognition may be given to those individuals who are residents of Los Altos Hills who perform heroic acts. The significance and frequency of these acts should indicate whether this type of Commendation should be presented at a City Council meeting.

Eagle and Golden Arrow Scouts
Young men and women who are residents of the Town of Los Altos Hills and become Eagle Scouts or Golden Arrow Scouts may be recognized by the Town. A Certificate of Commendation will be prepared and presented by the Mayor to the recipient at a City Council meeting.

Commissioner and Committee Member Resignations
If a Commissioner or Committee Member finds it necessary to resign prior to completion of his/her term, a framed Certificate of Appreciation will be presented at a City Council meeting. If a Commissioner or Committee Member completes the term of office, a plaque will be presented at a City Council meeting.

Regional Events and Recognition for Other Cities
Appropriate Certificates or Proclamations will be prepared for regional events or in response to requests from other cities. The Mayor will determine if the City Council is in favor of preparing the recognition and provide appropriate direction to staff.

Re: Coal Creek Open Space Preserve Wildland Fire Fuels Reduction Project Support Letter
Dear Wildfire Prevention Program Grant Review Committee, On behalf of the Town of Los Altos Hills, I am writing to express strong support for the Coal Creek Open Space Preserve Wildland Fire Fuels Reduction Project, a high‑priority wildfire prevention initiative led by the Midpeninsula Regional Open Space District (Midpen). This project directly advances regional public safety, protects critical infrastructure, and strengthens wildfire resilience for communities throughout the Santa Cruz Mountains and greater Peninsula region.

The project is located within the Coal Creek Open Space Preserve, near the intersection of Page Mill Road and Skyline Boulevard (SR 35)—a strategic ridgeline high-consequence wildfire corridor. The treatment area includes ~17 acres of forested open space and 3 miles of roadway influence zone adjacent to major evacuation routes serving thousands of households in the Wildlife Urban Interface including Los Altos Hills, Portola Valley, the Palo Alto foothills, and Skyline Ridge.

The planned fuels reduction work includes:
• Removal of dead and dying vegetation, French broom, and other invasive species • Thinning of dense understory brush and small trees
• Mastication of hazardous surface and ladder fuels
• Pruning and limbing of larger trees to reduce vertical fuel continuity • Use of both mechanical equipment and hand crews to ensure safe, ecologically sensitive treatment across varied terrain
ITEM 11D

Page Two
These actions will reduce wildfire intensity, slow potential fire spread along the Skyline Ridge corridor, and significantly improve ingress and egress for residents and emergency responders.

The project also protects PG&E transmission and distribution infrastructure that serves a broad region of the Peninsula and South Bay.

Importantly, this project is grounded in robust planning and interagency collaboration. It aligns with the CAL FIRE Strategic Fire Plan, the San Mateo and Santa Clara County Community Wildfire Protection Plans, regional Santa Cruz Mountains wildfire resilience priorities, and Midpen’s Wildland Fire Resilience Program EIR. Midpen is coordinating closely with CAL FIRE, the San Mateo Resource Conservation District, and the San Mateo and Santa Clara County Fire Safe Councils to ensure that treatments are effective, environmentally responsible, and community‑supported.

Given the increasing frequency and severity of wildfires across California, proactive fuel reduction projects such as this are essential to protecting lives, property, and critical infrastructure. The Coal Creek Open Space Preserve Wildland Fire Fuels Reduction Project is a responsible, science‑based, and urgently needed effort that will enhance wildfire resilience for communities across San Mateo and Santa Clara counties.

For these reasons, Los Altos Hills strongly supports this project and encourages full consideration and funding.

Thank you for your attention and for your continued commitment to wildfire prevention and community safety.

Best,
Rajiv Bhateja
Mayor
