Subject: Request for Council action regarding proposed Horizon detox facility at 101 N El Camino Real
Dear Members of the San Mateo City Council,

I am wriƟng as a concerned consƟtuent regarding the proposed Horizon detox and treatment facility at 101 N El Camino Real, which is being advanced by Horizon and San Mateo County.

Over the past several weeks, the Council has received more than 350 leƩers from residents expressing opposiƟon to this speciﬁc locaƟon. The volume of correspondence reﬂects the seriousness with which the community views this issue.

It appears that the Council in fact received early noƟﬁcaƟon from the County someƟme in 2025 about this proposed project. Despite this early noƟce, no public discussion, community outreach, or noƟﬁcaƟon to residents has taken place.

Why?

Many Councilmembers regularly publish newsleƩers, aƩend neighborhood meeƟngs, and present updates on major developments aﬀecƟng the city. Yet this project - which involves a 69-bed high-acuity detox and residenƟal treatment facility funded almost enƟrely with public funds - was never communicated to the residents of San Mateo unƟl February 2026.

That lack of early transparency by the applicant, the County, and City oﬃcials has contributed signiﬁcantly to the current situaƟon. When a major publicly funded project is advanced without informing the community or engaging local stakeholders, it inevitably erodes public trust. The Council’s inacƟon in this regard represents a serious shortcoming and has contributed to the circumstances we are facing today.

The San Mateo community is compassionate and understands that detox and treatment services are necessary. However, residents will not accept a site selecƟon process that appears to have been driven by secrecy, incomplete informaƟon, no community engageme
nt, and zero visible site analysis that disregards the safety concerns of our children, the elderly, and the general populaƟon.

Given the current situaƟon, I respecƞully ask the Council to take immediate correcƟve steps.

Speciﬁcally, I request that the Council:

1. Agendize a special Council meeƟng
Hold a publicly noƟced special meeƟng dedicated speciﬁcally to discussing the proposed facility at 101 N El Camino Real and act on the proposed items below.

2. Send a formal leƩer to the County and the relevant State grant agency The Council should formally state that no meaningful community engagement occurred prior to mid-February 2026, despite community outreach being a core requirement of the state grant funding that has now been condiƟonally awarded.

5 of 751

2 3. Document the sensiƟve uses surrounding the proposed site The leƩer should include a clear inventory of sensiƟve land uses within at least a 1,000-foot radius, including schools, childcare faciliƟes, residenƟal neighborhoods, and senior- serving faciliƟes, so that the applicant, state, and county oﬃcials fully understand the context of the proposed locaƟon.

4. Request to explore an alternaƟve site The Council should request that the County and the State allow the proposed facility to be relocated to a more appropriate seƫng - such as an industrial or medical zone - where safety concerns for vulnerable populaƟons and residents can be minimized while preserving the available state funding for treatment services.

Taking these steps would demonstrate that the City of San Mateo takes seriously both the need for treatment services and the responsibility to ensure that projects of this magnitude are planned transparently and responsibly.

Finally, it is important to recognize that 2026 is an elecƟon year, and Councilmembers will be seeking reelecƟon. The community is paying close aƩenƟon to how the Council responds to this issue, and the posiƟons taken on this maƩer will inevitably inﬂuence how residents evaluate their leadership.

I urge the Council to act promptly and construcƟvely to address the concerns of the community and help guide this project toward a more appropriate and broadly supported outcome.

I respecƞully request that this correspondence be entered into the public record and included in the City Council’s oﬃcial

correspondence for the next Council meeƟng so that Councilmembers may publicly address whether the City intends to take a posiƟon on the proposed site.

Sincerely,
Chris Chaudoir

Formal Objection to Inclusion of 101 N. El Camino Real in BHSA Plan and Objection to Closing Public Comment Period
Dear Members of the Behavioral Health Commission (BHC),

I am a parent of a student attending the Episcopal Day School of St. Matthew in San Mateo and the Chair of the Episcopal Day School Board of Trustees. I formally object to the BHSA Three-Year Integrated Plan regarding the proposed 69 Bed Horizon facility at 101 N. El Camino Real. I specifically object to Action Item 1 on the March 4th, 2026 agenda to "close the comment period."

The proposed Horizon project is 300% larger than the regional average at 69 beds and sits within 1,000 feet of schools and residential neighborhoods. To date, there has been no robust, location- focused community planning process involving directly impacted residents, schools, and businesses prior to inclusion of this project in the Plan.

I request:

- A 60-day extension of the public comment period.
- Establishment of an Ad Hoc Subcommittee for stakeholder engagement - Decoupling of the Horizon project from the FY 2026-29 Integrated Plan to identify an alternative location not within 1,000 feet of any school
I respectfully request that this email be entered into the public record for the BHC Meeting on March 4, 2026.

Thank you for your careful consideration.

Sincerely,

Chris Chaudoir
City of San Mateo Resident

Dear Members of the San Mateo City Council,

Over the past several weeks, the Council has received more than 350 letters from residents expressing opposition to this specific location. The volume of correspondence reflects the seriousness with which the community views this issue.

Many Councilmembers regularly publish newsletters, attend neighborhood meetings, and present updates on major developments affecting the city. Yet this project - which involves a 69-bed high-acuity detox and residential treatment facility funded almost entirely with public funds - was never communicated to the residents of San Mateo until February 2026.

That lack of early transparency by the applicant, the County, and City officials has contributed significantly to the current situation.

Given the current situation, I respectfully ask the Council to take immediate corrective steps.

Specifically, I request that the Council:

1. Agendize a special Council meeting
Hold a publicly noticed special meeting dedicated specifically to discussing the proposed facility at 101 N El Camino Real and act on the proposed items below.

2. Send a formal letter to the County and the relevant State grant agency

2 The Council should formally state that no meaningful community engagement occurred prior to mid- February 2026, despite community outreach being a core requirement of the state grant funding that has now been conditionally awarded.

3.

Objection to Proposed Horizon Facility at 101 N El Camino Real and Against Closure BHSA 3 Year Plan Public Comment Period
Dear Members of the Behavioral Health Commission,

As a parent at South Hillsborough School, I am wriƟng during the 30- day public comment period to formally object to the
BHSA Three-Year Integrated Plan as it relates to the proposed funding and development of the Horizon Center facility at 101 North El Camino Real.

This email speciﬁcally concerns AcƟon Item 1 on the agenda for the upcoming March 4 meeƟng to "close the comment period" for the BHSA Three-Year Integrated Plan.

I formally object to the Behavioral Health Services Act Integrated Plan for Fiscal Years 2026-29 based on the inclusion of the proposed 69-bed facility at 101 N. El Camino Real, referenced on pages 108 and 125 of the plan as the proposed SUD Campus by BHRS contractor Horizon Services.

This project represents an unprecedented regional outlier in size, reportedly 300 percent larger than the Bay Area average. It is located within 1,000 feet of schools, daycares, senior living faciliƟes, and residenƟal neighborhoods. To date, there has been no meaningful, site-speciﬁc community planning process involving directly impacted community members, stakeholders, or schools.

I respecƞully request the following:

- A 60-day extension of the public comment period, which would require voƟng against closing the comment period - Establishment of an Ad Hoc SubcommiƩee to engage stakeholders and analyze the site seƫng - Decoupling of 101 N. El Camino Real from the BHSA Integrated Plan for FY 2026-29 - IdenƟﬁcaƟon of an alternaƟve site that is not directly adjacent to schools, childcare centers, senior faciliƟes, or dense residenƟal neighborhoods

Pursuant to SecƟon 6.4 of the BHC Bylaws, I formally request that the Behavioral Health Commission establish an Ad Hoc SubcommiƩee for Horizon Center oversight. The current Three-Year Integrated Plan lists Community Program Planning and Data Review as core pillars. A project of this scale warrants a transparent, data-driven and site-speciﬁc review process.

Thank you for your consideraƟon.

Formal Objection to Inclusion of 101 N. El Camino Real in BHSA Plan and Objection to Closing Public Comment Period
Dear Members of the Behavioral Health Commission (BHC),

I am a resident of the City of San Mateo and write to formally object to the proposed Behavioral Health Services Act (BHSA) Three-Year Integrated Plan for Fiscal Years 2026-2029, speciﬁcally as it includes the proposed 69-bed Horizon Services facility at 101 N. El Camino Real.

My objecƟon applies directly to the March 4, 2026 "New Business" acƟon items on the San Mateo County Behavioral Health Commission MeeƟng Agenda, including:

- The proposed vote to close the 30-day public comment period on March 5, 2026; and - The proposed vote to submit the BHSA Integrated Plan to the Board of Supervisors.

The draŌ Plan explicitly references the Horizon project (pp. 108 and 125), describing a campus that includes sobering beds, ASAM 3.2 detox beds with IMS, and ASAM 3.5 residenƟal treatment beds. This represents a comparaƟvely large, high-intensity, 24/7 behavioral health facility proposed in a dense residenƟal corridor within approximately 1,000 feet of schools, daycares, senior living faciliƟes, and established neighborhoods.

The following concerns remain unresolved:

Insuﬃcient Public InformaƟon: To date, there has been minimal disclosure of site designs, operaƟonal details, safety protocols, intake standards, transportaƟon management, or neighborhood miƟgaƟon measures.

Lack of Meaningful Site-Speciﬁc Community Engagement: There has been no robust, locaƟon-focused community planning process involving directly impacted residents, schools, and businesses prior to inclusion of this project in the Plan.

Unprecedented Scale: At 69 beds, this facility is reportedly far larger than comparable Bay Area faciliƟes and represents a regional outlier in size and service concentraƟon.

Site SensiƟvity: The immediate proximity - less than 1,000 feet - to an elementary school and other vulnerable populaƟons, including daycares, senior living faciliƟes, and residenƟal neighborhoods, requires heightened transparency and analysis.

Closing the public comment period under these condiƟons would be premature and inconsistent with the spirit of transparent stakeholder engagement required under the Behavioral Health Services Act. AddiƟonally, moving forward with the proposed BHSA Plan for 2026-2029 without separaƟng and excluding the Horizon project at 101 N. El Camino Real places the broader Plan at potenƟal risk of legal challenge.

12 of 751

2 Accordingly, I respecƞully urge the Commission to consider one or both of the following acƟons:

ALTERNATIVE ACTION 1: Vote against closing the public comment period and instead extend it for 180 days to allow for meaningful, site-speciﬁc review and community engagement before submiƫng the Plan to the Board of Supervisors.

ALTERNATIVE ACTION 2: Proceed with submission of the broader BHSA Integrated Plan for Fiscal Years 2026-2029 only if the Commission votes to decouple and exclude the 101 N. El Camino Real Horizon project from the Plan.

In addiƟon, I strongly encourage the Commission to establish an Ad Hoc SubcommiƩee to assemble and disseminate all project plans and details, conduct a site-speciﬁc review, engage directly impacted stakeholders, evaluate alternaƟve sites, analyze scale, concentraƟon, and compaƟbility concerns, and report back with recommendaƟons.

SecƟon 6.4 of the BHC Bylaws empowers the Commission to form such subcommiƩees where appropriate. A project of this magnitude warrants separate, transparent review.

I respecƞully request that this email be entered into the public record for the BHC MeeƟng on March 4, 2026.

Thank you for your careful consideraƟon.

Sincerely,
Zoe Chen

Formal Objection to Inclusion of 101 N. El Camino Real in BHSA Plan and Objection to Closing Public Comment Period
Dear Members of the Behavioral Health Commission (BHC),

My name is Kathryn Collins and I am a parent of a student attending the Episcopal Day School of St.

Matthew in San Mateo, where I also serve as Vice Chair of the school's Board of Trustees.

I formally object to the BHSA Three-
Year Integrated Plan regarding the proposed 69 Bed Horizon facility at 101 N. El Camino Real. I specifically object to Action Item 1 on the March 4th, 2026 agenda to "close the comment period."

The proposed Horizon project is 300% larger than the regional average at 69 beds and sits within 1,000 feet of schools and residential neighborhoods. To date, there has been no robust, location-focused community planning process involving directly impacted residents, schools, and businesses prior to inclusion of this project in the Plan.

I request:

- A 60-day extension of the public comment period.
- Establishment of an Ad Hoc Subcommittee for stakeholder engagement - Decoupling of the Horizon project from the FY 2026-
29 Integrated Plan to identify an alternative location
not within 1,000 feet of any school
- the completion of a full Site Compatibility & Alternative Site Analysis that will be shared transparently with San Mateo residents

I respectfully request that this email be entered into the public record for the BHC Meeting on March 4, 2026.

Thank you for your careful consideration.

Subject: Request for Council action regarding proposed Horizon detox facility at 101 N El Camino Real
Dear Members of the San Mateo City Council,

I am writing as a concerned constituent to address the proposed Horizon detox and treatment facility at 101 N El Camino Real. While the community recognizes the necessity of such services in our county, the current site is inappropriate given its proximity to an elementary school, multiple senior living facilities, its adjacency to residential neighborhoods, and its distance from a hospital with 24/7/365 emergency services and from law enforcement. Despite the Council receiving notification of this project in 2025, there was no public outreach or resident notification until February 2026. These factors, combined with the egregious lack of transparency and community engagement about this project, have caused significant public concern.

The San Mateo community expects a transparent planning process that includes thorough site analysis and considers the safety of children, the elderly, and the general population. Given the scale of this facility, which would be the largest of its kind acro
ss all nine Bay Area counties, and its reliance on public funding, I respectfully request that the Council take the following immediate actions:

1. Agendize a Special Council Meeting: Hold a publicly noticed special Council meeting dedicated to a discussion
of the proposed facility at 101 N El Camino Real that would include both Horizon as well as all San Mateo County Supervisors.

2. Formal Communication with County and State Agencies: Send a formal letter to San Mateo County and the relevant state grant agency clarifying that no meaningful community engagement occurred prior to mid-February 2026, which is a core requirement for the conditionally awarded state grant that would find $25.5M to this specific project.

3. Document Sensitive Land Uses: Provide a clear inventory of sensitive land uses within a 1,000-foot radius of the site, including schools, childcare facilities, and senior-serving institutions.

4. Explore Alternative Sites: Request that the County and State relocate the facility to a more appropriate setting in San Mateo County to minimize impact on vulnerable populations while preserving funding for these essential services.

The community is closely monitoring how the Council responds to these concerns. I urge you to act promptly to guide this project toward a more appropriate and broadly supported location.

I respectfully request that this correspondence be entered into the public record and included in the official correspondence for the next Council meeting so that the City’s position may be publicly addressed.

Subject: Proposed Horizon detox and treatment facility at 101 N El Camino Real Dear Members of the San Mateo City Council,
I am writing as a concerned neighbor regarding the proposed Horizon detox and treatment facility at 101 N El Camino Real, which is being advanced by Horizon and San Mateo County.

It appears that the Council in fact received early notification from the County sometime in 2025 about this proposed project. Despite this early notice, no public discussion, community outreach, or notification to residents has taken place. Why?
Many Councilmembers regularly publish newsletters, attend neighborhood meetings, and present updates on major developments affecting the city. Yet this project - which involves a 69-bed high- acuity detox and residential treatment facility funded almost entirely with public funds - was never communicated to the residents of San Mateo until February 2026.

Given the current situation, I respectfully ask the Council to take immediate corrective steps.

Specifically, I request that the Council:

1. Agendize a special Council meeting
Hold a publicly noticed special meeting dedicated specifically to discussing the proposed facility at 101 N El Camino Real and act on the proposed items below.

Document the sensitive uses surrounding the proposed site The letter should include a clear inventory of sensitive land uses within at least a 1,000-foot radius, including schools, childcare facilities, residential neighborhoods, and senior-serving facilities, so that the applicant, state, and county officials fully understand the context of the proposed location.

I urge the Council to act promptly and constructively to address the concerns of the community and help guide this project toward a more appropriate and broadly supported outcome.

Formal Objection to Inclusion of 101 N. El Camino Real in BHSA Plan and Objection to Closing Public Comment Period
Follow Up Flag:

Follow up
Flag Status: Flagged
Dear Members of the Behavioral Health Commission (BHC),

I am a resident of the City of Hillsborough and write to formally object to the proposed Behavioral Health Services Act (BHSA) Three-Year Integrated Plan for Fiscal Years 2026–2029, specifically as it includes the proposed 69-bed Horizon Services facility at 101 N. El Camino Real.

My objection applies directly to the March 4, 2026 “New Business” action items on your agenda SMC BHS Commission Meeting Agenda, including:
 The proposed vote to close the 30-day public comment period on March 5, 2026; and  The proposed vote to submit the BHSA Integrated Plan to the Board of Supervisors.

The draft Plan explicitly references (but only simply) the Horizon project (pp. 108 and 125), describing a campus including sobering beds, ASAM 3.2 detox beds with IMS, and ASAM 3.5 residential treatment beds. This is a comparatively large, high-intensity, 24/7 behavioral health facility proposed in a dense residential corridor within approximately 1,000 feet of schools, daycares, senior living facilities, and established neighborhoods. The following concerns remain unresolved:

1. Insufficient Public Information: To date, there has been minimal disclosure of site designs, operational details, safety protocols, intake standards, transportation management, or neighborhood mitigation measures.

2. Lack of Meaningful Site-Specific Community Engagement: There has been no robust, location-focused community planning process involving directly impacted residents, schools, and businesses prior to inclusion of this project in the Plan.

40 of 751

2 3. Unprecedented Scale: At 69 beds, this facility is reportedly far larger than comparable Bay Area facilities and represents a regional outlier in size and service concentration.

4. Site Sensitivity: The immediate proximity of less than 1,000 feet to an elementary school and that of vulnerable populations such as daycares, senior living facilities, and residential neighborhoods require heightened transparency and analysis.

Closing the public comment period under these conditions would be premature and inconsistent with the spirit of transparent stakeholder engagement required under the Behavioral Health Services Act. Additionally, moving forward with the as-is proposed BHSA plan for 2026-29 without separating out and excluding just the Horizon 101 N. ECR project puts the entire BHSA plan in collective jeopardy of legal challenge.

Accordingly, I respectfully urge the Commission to consider one or all of the following actions:

ALTERNATIVE ACTION 1: Vote against closing the public comment period and instead vote to extend it for 180 days to allow for meaningful, site-specific review and community engagement before submitting the Plan to the Board of Supervisors. This would also include voting against submitting this plan to the Board of Supervisors.

ALTERNATIVE ACTION 2: Proceed with submission of the current as-is proposed broader BHSA Integrated Plan for Fiscal Years 2026-29 but only if the Commission votes to decouple and exclude the 101 N. El Camino Real Horizon project from the Plan.

In addition to the BHC adopting either Alternative Action 1 or 2, I highly encourage the BHC to establish an Ad Hoc Subcommittee to:
 Assemble and disseminate all project plans and details;  Conduct site-specific review;
 Engage directly impacted stakeholders;
 Evaluate alternative sites;
 Analyze scale, concentration, and compatibility concerns;  Report back with recommendations.

Section 6.4 of the BHC Bylaws empowers the Commission to form such subcommittees where appropriate. A project of this magnitude warrants separate, transparent review — not inclusion within a comprehensive countywide plan without focused scrutiny.

41 of 751

3 The Commission has an opportunity to demonstrate leadership, transparency, and responsiveness.

Excluding or pausing this single project does not undermine behavioral health services countywide — it ensures they are implemented responsibly and with community trust.

I respectfully request that this email be entered into the public record for the BHC Meeting on March 4, 2026.

Thank you for your careful consideration.

Sincerely,
Eric Abrahamson
City of Hillsborough Resident

Formal Objection to Inclusion of 101 N. El Camino Real in BHSA Plan and Objection to Closing Public Comment Period
Dear Members of the Behavioral Health Commission (BHC),

I am a resident of the City of San Mateo and write to formally object to the proposed Behavioral Health Services Act (BHSA) Three-Year Integrated Plan for Fiscal Years 2026-2029, specifically as it includes the proposed 69-bed Horizon Services facility at 101 N. El Camino Real.

My objection applies directly to the March 4, 2026 "New Business" action items on the San Mateo County Behavioral Health Commission Meeting Agenda, including:

- The proposed vote to close the 30-day public comment period on March 5, 2026; and - The proposed vote to submit the BHSA Integrated Plan to the Board of Supervisors.

The draft Plan explicitly references the Horizon project (pp. 108 and 125), describing a campus that includes sobering beds, ASAM 3.2 detox beds with IMS, and ASAM 3.5 residential treatment beds. This represents a comparatively large, high-intensity, 24/7 behavioral health facility proposed in a dense residential corridor within approximately 1,000 feet of schools, daycares, senior living facilities, and established neighborhoods.

The following concerns remain unresolved:

Insufficient Public Information: To date, there has been minimal disclosure of site designs, operational details, safety protocols, intake standards, transportation management, or neighborhood mitigation measures.

Lack of Meaningful Site-Specific Community Engagement: There has been no robust, location-focused community planning process involving directly impacted residents, schools, and businesses prior to inclusion of this project in the Plan.

Unprecedented Scale: At 69 beds, this facility is reportedly far larger than comparable Bay Area facilities and represents a regional outlier in size and service concentration.

Site Sensitivity: The immediate proximity - less than 1,000 feet - to an elementary school and other vulnerable populations, including daycares, senior living facilities, and residential neighborhoods, requires heightened transparency and analysis.

57 of 751

2 Closing the public comment period under these conditions would be premature and inconsistent with the spirit of transparent stakeholder engagement required under the Behavioral Health Services Act.

Additionally, moving forward with the proposed BHSA Plan for 2026-2029 without separating and excluding the Horizon project at 101 N. El Camino Real places the broader Plan at potential risk of legal challenge.

Accordingly, I respectfully urge the Commission to consider one or both of the following actions:

ALTERNATIVE ACTION 1: Vote against closing the public comment period and instead extend it for 180 days to allow for meaningful, site-
specific review and community engagement before submitting the Plan to the Board of Supervisors.

In addition, I strongly encourage the Commission to establish a n Ad Hoc Subcommittee to assemble and
disseminate all project plans and details, conduct a site-specific review, engage directly impacted stakeholders, evaluate alternative sites, analyze scale, concentration, and compatibility concerns, and report back with recommendations.

Section 6.4 of the BHC Bylaws empowers the Commission to form such subcommittees where appropriate. A project of this magnitude warrants separate, transparent review.

I respectfully request that this email be entered into the public record for the BHC Meeting on March 4, 2026.

Thank you for your careful consideration.

Sincerely,

Patrick Aitken

Many Councilmembers regularly publish newsletters, attend neighborhood meetings, and present updates on major developments affecting the city. Yet this project - which involves a 69- bed high-acuity detox and residential treatment facility funded almost entirely with public funds - was never communicated to the residents of San Mateo until February 2026.

City Council (San Mateo); City Mgr; City Attorney's Office; Clerk Subject: Stop the Horizon Project at 101 N. El Camino Real Immediately - Find a new location for it
Dear San Mateo City Councilmembers and San Mateo County Supervisors,

I am writing as a concerned resident to express my deep disappointment regarding the lack of transparency and community engagement surrounding the Horizon facility project. Although this project has progressed through County processes for months, many in our community have only recently become aware of it.

I urge you to prioritize the interests of your constituents and ensure a transparent decision-making process moving forward. We have previously expressed our opposition to placing this facility at 101 N El Camino Real, as we believe it will cause irreversible damage to our community.

We request that an alternative location be identified. Specifically, we believe the facility should be situated away from schools, senior communities, and dense residential areas, and instead be located closer to a police station and an emergency room.

I respectfully request that the County and City pause this project until the community receives full disclosure and answers to the following questions:

- How and when did this project originate, and who initiated it? - What roles did County and City officials play in advancing the proposal? - What analyses were conducted regarding traffic, neighborhood safety, and land-use compatibility? - What alternative locations were evaluated, and why were they rejected? - Why was the project only referenced in two brief paragraphs within the County’s 252-page BHSA plan?

Before a project of this magnitude moves forward—particularly one located less than 1,000 feet from an elementary school—residents deserve a clear explanation of the process. I urge you to halt this project until these matters are discussed publicly.

Thank you for your attention to this matter.

We respectfully request that the County and City pause and reconsider this project until the community receives full disclosure and answers to several fundamental questions:
• How and when did this project originate, and who initiated it? • What role did County and City officials play in supporting or advancing the proposal? • What analyses were conducted regarding traffic, neighborhood safety, and land-use compatibility?

Subject: Concerns About Horizon's Planned Sobering Center To the Honorable Jackie Speier, Lisa Diaz Nash, and Noelia Corzo:

My husband and I live at in Hillsborough. While we recognize the importance of having an alternative to incarceration for people under the influence of drugs or alcohol, we think that the location of the Center is harmful to the residential community. In our neighborhood we have both vulnerable young children (St. Matthews and South Hillsborough Schools are very close to the proposed location), as well as many senior citizens.

As a senior citizen myself, I know that I would not be able to fend off an attack from a person who has had too much to drink or who has aggressive behaviors.

A more appropriate location would be in an area of warehouses or office buildings, such as on the east side of Highway 101.

Even more problematic is the size of the proposed facility in a residential neighborhood. For example, the Horizon detox center on Palm Avenue in San Mateo has needed police response 33 times in 2025 -- and that facility only has 17 beds. The proposed El Camino facility would have 69 beds, and it is frightening to imagine driving or walking anywhere near 101 El Camino Real. In addition, people could wander from the facility and interfere with normal life in our neighborhood.

We --and our neighbors -- are so concerned about this project. We would greatly appreciate public officials finding a more appropriate location for the Center.

Thank you for your attention.

Best regards,
Susan J. Bardet

I am writing to voice my concerns regarding the proposed building of a two-story Sobering Center at the intersection of El Camino Real and El Cerrito Avenue in San Mateo.

This intersection is notorious for traffic accidents; a 69-unit, 2 story building would contribute to additional congestion and accidents.The comings and goings of drop-offs and pick-ups from this sobering center would be highly disruptive for both the safety of drivers and the residents in this neighborhood. Although there is a need for facilities of this nature, these facilities do not belong in the middle of a residential neighborhood that also includes elementary schools and senior living homes.

There are many other potential locations in the county more appropriate than this very congested intersection within this residential area. I disagree with Jaimie Campos, CEO of Horizon Treatment Services, that the center is justified "so that the drunk tank in the jail is not overflowing."

Thank you for your attention, I assume this matter is still open for discussion.

Subject: The Proposed Horizon Treatment Services Center in San Mateo

Dear Council Member Diaz Nash,

As a forty-year resident of San Mateo, including thirty years on De Sabla Road, I want to voice my opposition to the proposed location for the Horizon Treatment Services drug and alcohol recovery center at 101 North El Camino Real. I support the mission of this organization and understand the need for more services in San Mateo County, but have many concerns about this particular location.

This proposed use is incompatible with the composition of our largely residential neighborhood of single-family homes, condominiums and apartments (San Mateo Park, El Cerrito Park, Hillsborough Heights and Hillsborough Brewer subdivision) and the many schools and child-care centers close by.

It is my understanding that the recovery center would be a two-story building able to accommodate 69 beds including drop-off services for people under the influence of drugs or alcohol. As a 24-hour facility, this would have a much greater impact to our community than the private practice medical offices at that location today. The Horizon Treatment Center on Palm Avenue, which is in a largely industrial area of San Mateo, has just 17 beds. Apparently, they still had 33 reported police/sheriff department responses to escalation issues there in the past year. If the experience at the proposed site is similar (with 400% greater capacity) there will be a police/sheriff response in our neighborhood every three days. Perhaps the patients would be better served and supported by co-locating with other supportive services that already exist in the county.

We live in a walking neighborhood with close proximity to downtown, Caltrain, medical services and many churches, schools and childcare centers. Within two to three blocks of the proposed location are the following thriving community resources which could be negatively impacted by close proximity to this proposed treatment center:

The Peninsula Regent - 60 plus Retirement Community
The Versailles - 55 plus Retirement Community
Episcopal Day School of San Mateo - Pre-Kindergarten to 8th Grade Private School Muslim Children’s Garden - Two-year to nine-year old children (pre-school and after school care) Little Wonders: A Parent-Child Center - Three-month to 36-month old children (parent cooperative) The Modern Schoolhouse - Infant, Toddler, Pre-school Learning Center Kids Konnect - Infant Care and Pre-school
Chabad North Chai - Toddlers, Nursery, Pre-K and TK
Hillsborough South School - Public Elementary School

While I recognize the need for these types of facilities and support their mission, I hope that you take a close look at the impact this facility would have on our neighborhood and make every effort to find another more suitable location for this service. Thank you.

Objection to Proposed Horizon Facility at 101 N El Camino Real in San Mateo Dear Members of the Behavioral Health Commission,

As a parent at Hillsbrough schools, I am writing during the 30-day public comment period to formally object to the BHSA Three-Year Integrated Plan as it relates to the proposed funding and development of the Horizon Center facility at 101 North El Camino Real.

This email specifically concerns Action Item 1 on the agenda for the upcoming March 4 meeting to "close the comment period" for the BHSA Three-Year Integrated Plan.

This project represents an unprecedented regional outlier in size, reportedly 300 percent larger than the Bay Area average. It is located within 1,000 feet of schools, daycares, senior living facilities, and residential neighborhoods. To date, there has been no meaningful, site-specific community planning process involving directly impacted community members, stakeholders, or schools.

City Council (San Mateo); City Mgr; City Attorney's Office; Clerk Subject: STOP the Horizon Project at 101 N. El Camino Real Dear San Mateo City Councilmembers and San Mateo County Supervisors,

I am writing as a concerned San Mateo resident regarding the proposed Horizon DETOX facility at 101 North El Camino Real.

Like many in our community, I only recently learned about this project, even though it has been moving through county processes for months. Residents deserve to understand how this proposal advanced this far without meaningful community engagement or transparency. Since the Listening Session at the end of February we were provided conflicted documents with multiple inconsistencies about the proposed facility. We were told more public outreach would be provided, but the County hasn't followed through.

It's is almost a month since a very limited info session that didn't answer any of our questions.

I respectfully request that the city and county pause and reconsider the placement of this project. As a community, we demand full disclosure and answers to the following questions:

- Please provide a timeline of when the county was first approached and proposed this particular site. - What roles did county and city officials play in advancing the proposal? - What steps did our elective representatives take to ensure the proposed site would not harm the community they were elected to represent? i.e., did a county supervisor consult City Planning Department (name, if so and date of such contact), City Council members (who, if so and date of contact), neighborhood association representatives (who, if so?), any of San Mateo District 2 constituents?
- What analyses were conducted regarding traffic, fire, neighborhood safety, and land-use compatibility?

- What alternative locations were evaluated, and why were they rejected? - Why was the project referenced only briefly within the county’s 252-page BHSA plan?

Before a project of this magnitude moves forward in a residential area less than 1,000 feet from an elementary school, the public deserves complete transparency and a clear explanation of the decision- making process. Until this information is disclosed and discussed publicly, I request that the project be halted or an alternative location be found.

Thank you for your attention to this matter.

Best regards,

Formal Objection to Inclusion of 101 N. El Camino Real in BHSA Plan and Objection to Closing Public Comment Period
Dear Members of the Behavioral Health Commission (BHC),

I am a practicing physician and parent of a student attending the Episcopal Day School of St. Matthew in San Mateo. I formally object to the BHSA Three-Year Integrated Plan regarding the proposed 69 Bed Horizon facility at 101 N. El Camino Real. I specifically object to Action Item 1 on the March 4th, 2026 agenda to "close the comment period."

While I am very much in favor of providing incresaed resources to manage SUD in the regional population, the proposed Horizon project is being pushed forward too quickly. The Horizon facility is 300% larger than the regional average at 69 beds and sits within 1,000 feet of schools and residential neighborhoods. To date, there has been no robust, location-focused community planning process involving directly impacted residents, schools, and businesses prior to inclusion of this project in the Plan.

I request:

- A 60-day extension of the public comment period.
- Establishment of an Ad Hoc Subcommittee for stakeholder engagement - Decoupling of the Horizon project from the FY 2026-
29 Integrated Plan to identify an alternative location
not within 1,000 feet of any school

Formal Objection to Inclusion of 101 N. El Camino Real in BHSA Plan and Objection to Closing Public Comment Period
Dear Members of the Behavioral Health Commission (BHC),

I am a parent of a middle school student attending the Episcopal Day School of St. Matthew in San Mateo. I formally object to the BHSA Three-Year Integrated Plan regarding the proposed 69 bed Horizon facility at 101 N. El Camino Real. I specifically object to Action Item 1 on the March 4th, 2026 agenda to "close the comment period."

I request:

I’m very much in favor of programs to help those suffering with Substance Use Disorder, however a 69-bed facility is an unprecedented space of this type anywhere in the Bay Area. The overall neighborhood impact is deeply concerning. As a parent of a middle schooler, I am also particularly concerned about the interactions between school children and patients as they make use of the outdoor space both during recreation, as well as the transit times before and after school. Middle school activities start as early as 7:30 AM and can continue until as late as 8 PM at night. Placement of a facility of this type in a community must be done with great care.

I respectfully request that this email be entered into the public record for the BHC Meeting on March 4, 2026.

Thank you for your careful consideration.

Thank you Aleksander, for your email and support for the entire community. I have voiced my strong support against that project in that particular location!!!

David Canapa, County Supervisor and community leader, has also expressed his concern and support for our community and understands the importance of shutting down that particular location for the project.

There is multiple location options available for a project of this nature and magnitude in different locations on the Peninsula.

One of them can be down by coyote point, land is owned by SM country and there is already several other county operations there, such as a shooting range amongst other things. ( away from residential area )

Another one is down in Redwood City by the woman’s jail facilities, where there is no immediate residential homes close by.

The El Cerrito and El Camino area is located in proximity to some of the most expensive real estate homes in the county and the country. Many politicians also reside in the area and are totally aware of the concern at hand.

Everyone in their right mind knows that this area is not suitable for that type of situation and everyone should get behind this situation and resolve the matter immediately.

The county of SM needs to help these people, we all know people in that situation and some of us have had the nightmare of personally dealing with this exact problem in our own family.

However, as much as this is needed in our county and every other county in the state, we don’t need to punish all our neighbors with this grave problem.

Having previously served on the Sheriff’s Department advisory board, I urge all the bay area politicians to resolve this problem, without delay and appease the people of San Mateo in close proximity to this issue.

Thank You,

While I have previously reached out to some of you regarding this project, the growing concern within our community has reached a tipping point.

We are formally requesting more time for public discussion and a level of transparency that has, for whatever reason, been entirely absent from this process thus far. The community only recently learned of this project, despite the fact that it has been progressing through County processes for months. As residents, we deserve to know how and why this proposal advanced this far without meaningful community engagement. This lack of transparency is not the behavior we expect from our county representatives.

As our elected officials, we expect you to prioritize the safety of our community, our schools, our children, and our property. We are watching these proceedings closely, and the actions taken now will certainly be remembered by the voters when it comes time to express our confidence at the ballot box. This is a pivotal moment for you all to demonstrate whether you prioritize the well-being of your constituents or the interests of a small group. I believe it is a choice for you to make now, and the actions you take (or don't) will be remembered and promoted by residents and voters when it comes time to express our confidence at the ballot box or to support fundraising campaigns. It is time for you all to show if you care about your residents!
One way or another, we are committed to ensuring the truth behind the decisions that allowed this project to advance is made visible to both the public and the media.

While we do not dispute the potential need for such a facility, placing it in the middle of a residential area—flanked by schools, daycares, and retirement communities—is irresponsible, especially when less intrusive locations remain unutilized.

I'm a resident of the City of San Mateo and I write you to formally object to the proposed Behavioral Health Services Act (BHSA) Three-Year Integrated Plan for Fiscal Years 2026–2029, specifically as it includes the proposed 69-bed Horizon Services facility at 101 N. El Camino Real in San Mateo.

My objection applies directly to the March 4, 2026 “New Business” action items on your agenda SMC BHS Commission Meeting Agenda, a) The proposed vote to close the 30-day public comment period on March 5, 2026; and b) The proposed vote to submit the BHSA Integrated Plan to the Board of Supervisors.

Although I fully support rehabilitation efforts for those in need, I believe the proposed Horizon facility at 101 N. El Camino in San Mateo is in the wrong location and of the wrong size. 1) The corner of El Camino Real and El Cerrito Ave has already more than its fair share of traffic issues and accidents.

El
Cerrito Ave carries a large amount of traffic from our neighbors in Hillsborough. 2) This area has restricted street parking. Unless the proposed facility is designed to accommodate parking for all its staff and guests, this development will make street parking even worst. 3) I understand, at 69 beds, the proposed Horizon center will be among the largest in the whole Bay Area. I understand the typical size of these facilities in the Bay Area is around 21 beds. So if the county sticks to that average and break down the 69 proposed facility in 3 locations not only it will be easier to locate suitable parcels but will spread those facilities over different cities within the county and hopefully closer to those folks in need of such services. 4) There are already several facilities that provide similar services that are located in the City of San Mateo. Horizon has a facility on 2251 Palm Avenue. Healthright360 has residential facilities at 900 Laurel Ave and 202 E Bellevue Ave. Project Ninety has a location on 416 2nd Ave. I'm not aware of any other city within the county that has more facilities. So why to add another one on the same city? Not only one more but one of the largest in the whole Bay Area? This is not only unfair to us residents of city of San Mateo hosting these facilities but to those patients that need and use those services and are located in other cities within the county. 5) There are several childcare centers and an elementary school near the proposed location. The fact that there is current statutory barriers for location of dispensaries and there is proposed legislation (SB1060) to prevent this type of facilities within 1000 feet from schools and day care centers speaks about the sensitivity of this matter.

Unfortunately as a Resident that lives very close to the proposed Facility, and therefore a clear stakeholder on this project ,
the first time I learned about this project was a few weeks ago when Horizon notified me about a “Listening Session” they were going to have on February 19, 2026 This is well AFTER they had already submitted their application to a grant to finance this project and secured a resolution from SM Board of Supervisors with a 10% match..

Accordingly, I respectfully urge the Commission to consider one or all of the following actions:

ALTERNATIVE ACTION 1: Vote against closing the public comment period and instead vote to extend it for 60 days to allow for meaningful, site-specific review and community engagement before submitting the Plan to the Board of Supervisors. This would also include voting against submitting this plan to the Board of Supervisors.

118 of 751

2 In addition to the BHC adopting either Alternative Action 1 or 2, I highly encourage the BHC to establish an Ad Hoc Subcommittee to:
- Assemble and disseminate all project plans and details; - Conduct site-specific review;
- Engage directly impacted stakeholders;
- Evaluate alternative sites;
- Analyze scale, concentration, and compatibility concerns; - Report back with recommendations.

I respectfully request that this email be entered into the public record for the BHC Meeting on March 4, 2026.

Thank you for your consideration.

Sincerely,

Mario Caceres

Formal Objection to Inclusion of 101 N. El Camino Real in BHSA Plan and Objection to Closing Public Comment Period
Dear Members of the Behavioral Health Commission,

As a parent at South Hillsborough Elementary School, I am writing during the 30- day public comment period to
formally object to the BHSA Three-Year Integrated Plan as it relates to the proposed funding and development of the Horizon Center facility at 101 North El Camino Real.

This email specifically concerns Action Item 1 on the agenda for the upcoming March 4 meeting to “close the comment period” for the BHSA Three-Year Integrated Plan.

131 of 751

2 Additionally, my opposition is grounded in the following core concerns:
 Immediate Threat to Child and Pedestrian Safety: South Elementary School is a mere 0.5 miles away, and the surrounding streets are heavily utilized by families and children walking to school, the library, and Central Park. Because this is a voluntary facility, individuals brought in for sobering or detox can leave after a short 18-to-24-hour period. Discharging individuals who have recently experienced a substance crisis directly onto our neighborhood sidewalks introduces an unpredictable and unacceptable safety risk to our children.
 Lack of Integration with County Emergency Infrastructure: While this site is near the Sutter Health Mills campus, it is important to note that Mills is a private facility that no longer operates an Emergency Room. A high-intensity, county-run detox and sobering facility should be co-located with the County’s own acute emergency and psychiatric resources—specifically at the San Mateo Medical Center on 37th Avenue. Isolating a county crisis center in a standalone building, completely disconnected from the county's emergency safety-net hospital, is an inefficient and unsafe planning decision.
 Drastic and Incompatible Shift in Land Use: The proposed location currently serves as quiet, appointment-based medical and professional offices. Converting this tight lot into an intensive, 69-bed facility that requires constant police drop-offs, ambulance traffic, and 24/7 operations is entirely incompatible with the surrounding environment. It borders premium, single-family neighborhoods and a bustling commercial corridor that is simply not equipped to manage the ingress, egress, and loitering associated with a crisis center.

The safety of our children and the integrity of our neighborhoods must be the priority. This facility will undoubtedly alter the character of this corridor, depress local property values, and create public safety challenges that our neighborhood should not be forced to absorb.

I respectfully request that this email be entered into the public record for the BHC Meeting on March 4, 2026.

Thank you for your careful consideration.

Dear Members of the San Mateo City Council and San Mateo County Board of Supervisors, I am writing to you as a deeply concerned San Mateo County homeowner and parent regarding the proposed 69-bed Horizon Treatment Center at 101 North El Camino Real. Like many in our community, I only recently learned about this project despite the fact that it has been quietly progressing through the city and county processes for months.

While we absolutely support the need for addiction treatment, placing a high-turnover crisis center at this specific location is a reckless planning decision. Before allowing this to move forward, the County and City must address the glaring logistical and safety flaws of this site:
 Unacceptable Safety Risks to Children: Because sobering stations operate on short-term, voluntary holds (often 18 to 24 hours), individuals will be discharged directly into a dense pedestrian zone. My seven-year-old daughter is in second grade in elementary school within walking distance, less than half a mile from this site. Introducing unpredictable foot traffic from a crisis center into a corridor where families and children walk daily is an unacceptable risk.  Disconnected from County Infrastructure: The county has a 18.7-acre San Mateo Medical Center campus on 37th Avenue, which includes a 13-bed crisis center (Serenity House) on the campus, which has hospital-grade security and deep buffers. In contrast, 101 N. El Camino has zero buffer, and the nearby private Mills Health Center has no Emergency Room. Forcing a facility five times the size of Serenity House onto an isolated commercial lot surrounded by the community is dangerous and inefficient.
 County-Wide Traffic on Local Streets: This facility is intended to serve the entire county, meaning individuals in acute crisis will be transported here from Daly City to East Palo Alto. Yet, this site is not immediately accessible from major thoroughfares like US-101 or I-280, requiring police and ambulances to navigate heavily trafficked, local residential streets. Furthermore, it is miles away from the San Mateo Police Department headquarters. Routing county-wide crisis traffic into a residential bottleneck far from law enforcement hubs is a logistical failure.  Massive Scale on a Tiny Lot: This lot is less than half an acre—roughly the size of three single-family homes lot. Cramming a 69-bed facility requiring 24/7 operations, police drop-offs, and ambulance staging onto this tiny footprint at the immediate gateway into residential neighborhoods is a drastic and incompatible shift in land use. I drive by this intersection daily, and Tilton Road / El Cerrito as single lane roads with tight intersections, creating a logistical and safety nightmare at that intersection.

136 of 751

3 Residents deserve to know how and why this flawed proposal advanced this far without meaningful community engagement. I respectfully request that the County and City immediately pause and reconsider this project until the community receives full disclosure and answers to these fundamental questions:
 How and when did this project originate, and who initiated it?  What role did County and City officials play in supporting or advancing the proposal?  What analyses were conducted regarding traffic, neighborhood safety, and land-use compatibility?  What alternative locations were evaluated, and why were they rejected in favor of this site?  Why was the project referenced only in two brief paragraphs within the County’s 252-page BHSA plan?

Before a massive crisis center moves forward directly adjacent to family homes and a short walk from a elementary school classrooms, residents deserve complete transparency, meaningful engagement, and a clear explanation of the decision-making process.

Until that information is fully disclosed and discussed publicly, I urge you to stop this project and advocate for relocating this facility to a proper, integrated medical campus where it belongs.

Thank you for your attention to this critical matter.

Sincerely,
Gene Chan

Subject: Concern regarding proposed detox facility at 101 N El Camino Real Dear Members of the San Mateo City Council,
I’m writing as a parent of children who attend school near the proposed Horizon detox and treatment facility at 101 N El Camino Real.

I want to acknowledge upfront that substance abuse treatment and detox services are important and necessary in our county. My concern is not the need for these services, but the specific location selected for a facility of this size.

The proposed site is close to an elementary school community, several senior living facilities and residential neighborhoods. From a parent’s perspective, it is difficult to understand why a large detox facility would be placed so close to a school environment where hundreds of children are present every day. It also appears the site is not particularly close to a hospital with 24/7 emergency services.

Equally concerning is how recently many families and neighbors learned about the project. From what I understand, the City was notified in 2025, but many in the immediate school and neighborhood community only became aware of the proposal in February. For a project that would become the largest detox facility across the nine Bay Area counties and is receiving significant public funding, the level of early community engagement appears to have been limited.

Given these concerns, I respectfully ask the Council to consider the following steps:

1. Schedule a publicly noticed Council meeting dedicated specifically to the proposed facility at 101 N El Camino Real, with participation from Horizon and representatives from San Mateo County.

2. Communicate formally with the County and relevant state agencies noting that community outreach began very recently relative to the timeline of the project.

3. Provide a clear inventory of sensitive uses within roughly 1,000 feet of the site, including schools, childcare providers, and senior-serving facilities.

4. Work with the County and State to evaluate whether a more appropriate site within San Mateo County could be identified that would still support these essential services while reducing the impact on nearby schools and vulnerable populations.

Many parents in the school community are only now learning about this proposal and trying to better understand its implications. A transparent process and thoughtful consideration of location would significantly address those concerns.

Thank you for your time and attention. I would appreciate including this correspondence in the public record for the next Council meeting.

Subject: Request for Council action regarding proposed Horizon detox facility at 101 N El Camino Real
Dear Members of the San Mateo City Council,

I am following up as a concerned constituent to address the proposed Horizon detox and treatment facility at 101 N El Camino Real. While the community recognizes the necessity of such services in our county, the current site is inappropriate given its proximity to an elementary and middle school, multiple senior living facilities, its adjacency to residential neighborhoods, and its distance from a hospital with 24/7/365 emergency services and from law enforcement. Despite the Council receiving notification of this project in 2025, there was no public outreach or resident notification until February 2026. These factors, combined with the general lack of transparency and community engagement about this project, have caused significant public concern.

1. Agendize a Special Council Meeting: Hold a publicly noticed special Council meeting dedicated to a discussion of the proposed facility at 101 N El Camino Real that would include both Horizon as well as all

3. Document Sensitive Land Uses: Provide a clear inventory of sensitive land uses within a 1,000-foot radius of the site, including schools, childcare facilities, and senior-serving institutions.

The community is closely monitoring how the Council responds to these concerns. I urge you to act promptly to guide this project toward a more appropriate and broadly supported location.

Objection to Proposed Horizon Facility at 101 N El Camino Real and Against Closure BHSA 3 Year Plan Public Comment Period
Dear Members of the Behavioral Health Commission,

This email specifically concerns Action Item 1 on the agenda for the upcoming March 4 meeting to "close the comment period" for the BHSA Three-Year Integrated Plan.

This project represents an unprecedented regional outlier in size, reportedly 300 percent larger than the Bay Area average. It is located within 1,000 feet of schools, daycares, senior living facilities, and residential neighborhoods. To date, there has been no meaningful, site-specific community planning process involving directly impacted community members, stakeholders, or schools.

I respectfully request the following:

Objection to Inclusion of 101 N. El Camino Real in BHSA Plan and Objection to Closing Public Comment Period

Dear Members of the Behavioral Health Commission (BHC),

I am a resident of the City of San Mateo and write to formally object to the proposed Behavioral Health Services Act (BHSA) Three-Year Integrated Plan for Fiscal Years 2026-2029, specifically as it includes the proposed 69-bed Horizon Services facility at 101 N. El Camino Real.

My objection applies directly to the March 4, 2026 "New Business" action items on the San Mateo County Behavioral Health Commission Meeting Agenda, including:

- The proposed vote to close the 30-day public comment period on March 5, 2026; and - The proposed vote to submit the BHSA Integrated Plan to the Board of Supervisors.

The following concerns remain unresolved:

Unprecedented Scale: At 69 beds, this facility is reportedly far larger than comparable Bay Area facilities and represents a regional outlier in size and service concentration.

Closing the public comment period under these conditions would be premature and inconsistent with the spirit of transparent stakeholder engagement required under the Behavioral Health Services Act. Additionally, moving forward with the proposed BHSA Plan for 2026-2029 without separating and excluding the Horizon project at 101 N. El Camino Real places the broader Plan at potential risk of legal challenge.

Accordingly, I respectfully urge the Commission to consider one or both of the following actions:

ALTERNATIVE ACTION 1: Vote against closing the public comment period and instead extend it for 180 days to allow for meaningful, site-specific review and community engagement before submitting the Plan to the Board of Supervisors.

166 of 751

2 ALTERNATIVE ACTION 2: Proceed with submission of the broader BHSA Integrated Plan for Fiscal Years 2026-2029 only if the Commission votes to decouple and exclude the 101 N. El Camino Real Horizon project from the Plan.

In addition, I strongly encourage the Commission to establish an Ad Hoc Subcommittee to assemble and disseminate all project plans and details, conduct a site-
specific review, engage directly impacted stakeholders, evaluate alternative sites, analyze scale, concentration, and compatibility concerns, and report back with recommendations.

Section 6.4 of the BHC Bylaws empowers the Commission to form such subcommittees where appropriate. A project of this magnitude warrants separate, transparent review.

I respectfully request that this email be entered into the public record for the BHC Meeting on March 4, 2026.

Thank you for your careful consideration.

I am writing as a concerned San Mateo resident regarding the proposed Horizon DETOX facility at 101 North El Camino Real.

Like many in our community, I only recently learned about this project despite the fact that it has been progressing through County processes for months. Residents deserve to know how and why this proposal advanced this far without meaningful community engagement or transparency.

I respectfully request that the County and City pause and reconsider this project until the community receives full disclosure and answers to several fundamental questions:
• How and when did this project originate, and who initiated it? • What role did County and City officials play in supporting or advancing the proposal? • What analyses were conducted regarding traffic, neighborhood safety, and land-use compatibility? • What alternative locations were evaluated, and why were they rejected in favor of this site? • Why was the project referenced only in two brief paragraphs within the County’s 252-page BHSA plan? • Why was there no impact report shared with impacted community members and organizations, or any request for feedback / perspective from community members and organizations? Before a project of this magnitude moves forward in a residential community and just less than 1,000 feet from an elementary school, residents deserve complete transparency, meaningful engagement, and a clear explanation of the decision-making process.

Until that information is fully disclosed and discussed publicly, I respectfully request that the project be stopped and reconsidered.

Thank you for your attention to this matter.

It appears that the Council in fact received early notification from the County sometime in 2025 about this proposed project. Despite this early notice, no public discussion, community outreach, or notification to residents has taken place. Why?
Many Councilmembers regularly publish newsletters, attend neighborhood meetings, and present updates on major developments affecting the city.

I am writing as a concerned neighbor regarding the proposed Horizon detox and treatment facility at 101 N El Camino Real, which is being advanced by Horizon and San Mateo County.

It appears that the Council in fact received early notification from the County sometime in 2025 about this proposed project. Despite this early notice, no public discussion, community outreach, or notification to residents has taken place. Why?
Many Councilmembers regularly publish newsletters, attend neighborhood meetings, and present updates on major developments affecting the city. Yet this project - which involves a 69-bed high-acuity detox and residential treatment facility funded almost entirely with public funds - was never communicated to the residents of San Mateo until February 2026.

Given the current situation, I respectfully ask the Council to take immediate corrective steps.

Specifically, I request that the Council:

1. Agendize a special Council meeting
Hold a publicly noticed special meeting dedicated specifically to discussing the proposed facility at 101 N El Camino Real and act on the proposed items below.

188 of 751

2 Finally, it is important to recognize that 2026 is an election year, and Councilmembers will be seeking reelection. The community is paying close attention to how the Council responds to this issue, and the positions taken on this matter will inevitably influence how residents evaluate their leadership.

I urge the Council to act promptly and constructively to address the concerns of the community and help guide this project toward a more appropriate and broadly supported outcome.

Sincerely,
Jay Goldstein

Dear Members of the San Mateo City Council,

I am writing as a concerned constituent regarding the proposed Horizon detox and treatment facility at 101 N El Camino Real, which is being advanced by Horizon and San Mateo County.

That lack of early transparency by the applicant, the County, and City officials has contributed significantly to the current situation.

When a major publicly funded project is advanced without informing the community or engaging local stakeholders, it inevitably erodes public trust. The Council’s inaction in this regard represents a serious shortcoming and has contributed to the circumstances we are facing today.

Given the current situation, I respectfully ask the Council to take immediate corrective steps.

1. Agendize a special Council meeting

Formal Objection to Inclusion of 101 N. El Camino Real in BHSA Plan and Objection to Closing Public Comment Period
Dear Members of the Behavioral Health Commission (BHC),

I am a resident of the City of San Mateo and live on De Sabla Road. I wanted to write to formally object to the proposed Behavioral Health Services Act (BHSA) Three-Year Integrated Plan for Fiscal Years 2026– 2029, specifically as it includes
the proposed 69-bed Horizon Services facility at 101 N. El Camino Real.

My objection applies directly to the March 4, 2026 “New Business” action items on your agenda SMC BHS Commission Meeting Agenda, including:
• The proposed vote to close the 30-day public comment period on March 5, 2026; and • The proposed vote to submit the BHSA Integrated Plan to the Board of Supervisors.

planning process involving directly impacted residents, schools, and businesses prior to inclusion of this project in the Plan.

3. Unprecedented Scale: At 69 beds, this facility is reportedly far larger than comparable Bay Area facilities and represents a regional outlier in size and service concentration.

Accordingly, I respectfully urge the Commission to consider one or all of the following actions:

In addition to the BHC adopting either Alternative Action 1 or 2, I highly encourage the BHC to establish an Ad Hoc Subcommittee to:
• Assemble and disseminate all project plans and details;

Formal Objection to Inclusion of 101 N. El Camino Real in BHSA Plan and Objection to Closing Public Comment Period
Dear Members of the Behavioral Health Commission (BHC), I am a resident of the City of Hillsborough and write to formally object to the proposed Behavioral Health Services Act (BHSA) Three-Year Integrated Plan for Fiscal Years 2026-2029, specifically as it includes the proposed 69-bed Horizon Services facility at 101 N.

Closing the public comment period under these conditions would be premature and inconsistent with the spirit of transparent stakeholder engagement required under the Behavioral Health Services Act. Additionally, moving forward with the as-is proposed BHSA plan for 2026-
29 without separating out and excluding just the Horizon 101 N.

Accordingly, I respectfully urge the Commission to consider one or all of the following actions:

2 ALTERNATIVE ACTION 2: Proceed with submission of the current as-is proposed broader BHSA Integrated Plan for Fiscal Years 2026-29 but only if the Commission votes to decouple and exclude the 101 N. El Camino Real Horizon project from the Plan.

Section 6.4 of the BHC Bylaws empowers the Commission to form such subcommittees where appropriate. A project of this magnitude warrants separate, transparent review, not inclusion within a comprehensive countywide plan without focused scrutiny.

Concerns About the Horizon DETOX Project at 101 N. El Camino Real Dear Councilmembers and Supervisors,

I'm writing as a San Mateo resident and physician who has significant concerns about the proposed Horizon DETOX facility at 101 North El Camino Real.

I only learned about this project recently, despite it having moved through County processes for months.

That alone troubles me. A proposal of this scale, in a residential neighborhood less than 1,000 feet from an elementary school, should not advance this far without the community having a genuine seat at the table.

I'd ask our elected officials here:
 How did this project originate, and who drove it forward?  What role did County and City officials play in advancing it?  Were traffic, safety, and land-
use impacts actually studied? What about the distance from several elderly care facilities and elementary schools?
 What alternative sites were considered, and why was this one chosen?  Why did a 252-page County BHSA plan reference this project in just two paragraphs?

I'm not opposed to thoughtful solutions for our community's health needs. But good intentions don't excuse a flawed process or an outcome clearly dangerous for our children. Residents deserve full transparency, real engagement, and a clear accounting of how this decision was made.

I'm asking that the project be paused until those answers are provided publicly and completely.

Thank you for taking this seriously.

To date, there has been no meaningful, site-specific community planning process involving directly impacted community members, stakeholders, or schools.

I respectfully request the following:

Formal Objection to Inclusion of 101 N. El Camino Real in BHSA Plan and Objection to Closing Public Comment Period

Dear Members of the Behavioral Health Commission (BHC),

I am member of the congregation of The Episcopal Church of St. Matthew, located at 1 S. El Camino Real, San Mateo. I formally object to the BHSA Three-
Year Integrated Plan regarding the proposed 69 Bed
Horizon facility at 101 N. El Camino Real. I specifically object to Action Item 1 on the March 4th, 2026 agenda to "close the comment period."

The proposed Horizon project is 300% larger than the regional average at 69 beds and sits within 1,000 feet of schools including the Episcopal Day School of St Matthew’s, and is surrounded by residential neighborhoods. To date, there has been no robust, location-focused community planning process involving directly impacted residents, schools, and businesses prior to inclusion of this project in the Plan.

I request:

I respectfully request that this email be entered into the public record for the BHC Meeting on March 4, 2026.

Thank you for your careful consideration.

Sincerely,

Formal Objection to Inclusion of 101 N. El Camino Real in BHSA Plan and Objection to Closing Public Comment Period
Dear Members of the Behavioral Health Commission (BHC),

I am a resident of the City of San Mateo and write to formally object to the proposed Behavioral Health Services Act (BHSA) Three- Year Integrated Plan for Fiscal Years 2026-2029, specifically as it includes the proposed 69-bed Horizon Services facility at 101 N. El Camino Real.

My objection applies directly to the March 4, 2026 "New Business" action items on the San Mateo County Behavioral Health Commission Meeting Agenda, including:

- The proposed vote to close the 30-day public comment period on March 5, 2026; and - The proposed vote to submit the BHSA Integrated Plan to the Board of Supervisors.

The following concerns remain unresolved:

Unprecedented Scale: At 69 beds, this facility is reportedly far larger than comparable Bay Area facilities and represents a regional outlier in size and service concentration.

Closing the public comment period under these conditions would be premature and inconsistent with the spirit of transparent stakeholder engagement required under the Behavioral Health Services Act. Additionally, moving forward with the proposed BHSA Plan
for 2026-2029 without separating and excluding the Horizon project at 101 N. El Camino Real places the broader Plan at potential risk of legal challenge.

Accordingly, I respectfully urge the Commission to consider one or both of the following actions:

ALTERNATIVE ACTION 1: Vote against closing the public comment period and instead extend it for 180 days to allow for meaningful, site-specific review and community engagement before submitting the Plan to the Board of Supervisors.

In addition, I strongly encourage the Commission to establish an Ad Hoc Subcommittee to assemble and disseminate all project plans and details, conduct a site-specific review, engage directly impacted stakeholders, evaluate alternative sites, analyze scale, concentration, and compatibility concerns, and report back with recommendations.

Section 6.4 of the BHC Bylaws empowers the Commission to form such subcommittees where appropriate. A project of this magnitude warrants separate, transparent review.

Re: Proposed Horizon Recovery Center, 101 N. El Camino Real, San Mateo — Demand for Accountability, Transparency, and Immediate Review

Dear Governor Newsom, Senator Becker, Members of the Board of Supervisors, and County Executive Callagy,

We are writing on behalf of the concerned residents of San Mateo and Hillsborough to express our outrage — and we will not mince words — at the manner in which $25.5 million in Proposition 1 taxpayer funds have been committed to Horizon Services, Inc. for a 69-bed behavioral health facility at 101 N. El Camino Real, without meaningful community notification, without public process, and without any credible analysis of location.

This letter is not about opposition to behavioral health treatment. We are not against treatment. We are vehemently, unequivocally against this location — and we demand to know how this decision was made, by whom, and why the community was deliberately excluded from that process.

The State of California announced on March 11, 2026 that $25.5 million in Proposition 1 bond funds have been awarded to Horizon. The residents most directly impacted by this facility learned about this project not from their elected officials, not from a public hearing, and not from any required community engagement process — they learned about it from a newspaper article and a neighborhood email chain.

That is a failure of governance so fundamental that it demands an immediate and formal response.

Let us be direct about what Proposition 1 requires. The very mandate of these bond funds includes

261 of 751

2 community notification and community buy-in. That did not happen here. The San Mateo County Board of Supervisors approved a $2 million opioid settlement fund commitment as a local match — burying it in a Consent Agenda item on October 21, 2025, passed without question, without discussion, and without a single word of public comment. That is not transparency. That is a deliberate end- run around the public
process.

When Supervisor Corzo convened a virtual "listening session" on February 19, 2026, she led and managed that meeting in her official capacity as a County Supervisor — controlling the flow of questions,
determining which concerns would be addressed, and presenting the project as effectively decided.

Residents left that meeting with the clear and reasonable understanding that this was a County- sponsored proceeding. And yet the County now appears poised to characterize it as a private Horizon corporate event. That characterization is not credible.

We also demand answers to the following questions, which have not been addressed by anyone in a position of authority:

Where is the traffic analysis? The proposed facility sits at what is widely regarded as one of the most dangerous and congested intersections on the peninsula — El Cerrito Avenue and El Camino Real. A 69- bed, 24-hour facility will generate significant traffic, parking demand, emergency service calls, and pedestrian activity at a corner that already poses serious safety risks. Where is the CEQA review? Where is the environmental analysis? Where is any analysis at all?

Where is the site selection process? San Mateo County is geographically large. It has significant commercial and office vacancy. There are locations near existing health infrastructure, law enforcement, and County facilities that would be far more appropriate for this use. The County/Horizon paid above asking price for a premium medical property in a dense residential corridor. No public accounting of alternative sites has ever been provided. Why not?

Where is the consideration of proximity? This facility is proposed less than 800 feet from two elementary schools and two nursery schools. It is surrounded by senior housing, churches, residential neighborhoods, and one of the busiest intersections in the region. The community deserves a rigorous, transparent analysis of these impacts — not a Consent Agenda item passed in silence.

We want to ask each of you something directly.

Governor Newsom: you have announced this award as a success story for Proposition 1. Would you consider it equally successful if this facility were located down the street from one of your homes? The residents of El Cerrito Avenue, West Santa Inez, Bridge Street, and Ericson Avenue did not choose to become a test case for state behavioral health policy. They chose their neighborhood for its schools, its community, its safety and peaceful existence. They deserve the same consideration you would expect for yours.

Senator Becker: your constituents are asking how you would feel if this facility were proposed at the corner of Valparaiso and El Camino Real in Menlo Park. We suspect the answer would involve a great deal more process, a great deal more community engagement, and a great deal more scrutiny of the site selection. Your district includes this community. We are asking you to act like it.

County Executive Callagy: the County committed $2 million in public funds to this project without

262 of 751

3 community input. We ask you to consider how you would respond if this facility were proposed on your street in Foster City. The residents of San Mateo deserve the same standard of care.

Members of the Board of Supervisors: you passed this item without discussion, without public comment, and without any apparent consideration of the community impact. That is not what public service looks like. We are asking you to answer for it.

We are organized. We are engaged. We are not going away. The concerned residents of San Mateo and Hillsborough are actively pursuing every legal, procedural, and civic avenue available to us, including mandating proper site evaluations, engagement with state legislators, and the creation of a legal fund to support this fight. We are also prepared to raise funds to purchase this property outright.

The money has been committed. But this project is not built. There is still time to do this right — to conduct a genuine site analysis, to engage the community as Proposition 1 requires, and to find a location that serves the mission of behavioral health treatment without imposing avoidable harm on a residential neighborhood full of children, seniors, and families attending to daily life.

We are asking you to stop, to look, and to listen. That is not too much to ask of the people we elected and appointed to represent us.

Respectfully and without reservation,

The Concerned Residents of San Mateo and Hillsborough
El Cerrito Avenue, West Santa Inez, Bridge Street, Ericson Avenue, Tilton, and surrounding neighborhoods

Subject: Notice from a concerned citizen - Horizon detox and treatment center Dear Members of the San Mateo City Council,
I am writing as a concerned neighbor regarding the proposed Horizon detox and treatment facility at 101 N El Camino Real, which is being advanced by Horizon and San Mateo County.

It appears that the Council in fact received early notification from the County sometime in 2025 about this proposed project. Despite this early notice, no public discussion, community outreach, or notification to residents has taken place. Why?
Many Councilmembers regularly publish newsletters, attend neighborhood meetings, and present updates on major developments affecting the city. Yet this project - which involves a 69-bed high-acuity detox and residential treatment facility funded almost entirely with public funds - was never communicated to the residents of San Mateo until February 2026.

Given the current situation, I respectfully ask the Council to take immediate corrective steps.

Specifically, I request that the Council:

1. Agendize a special Council meeting
Hold a publicly noticed special meeting dedicated specifically to discussing the proposed facility at 101 N El Camino Real and act on the proposed items below.

2. Send a formal letter to the County and the relevant State grant agency The Council should formally state that no meaningful community engagement occurred prior to

2 mid-February 2026, despite community outreach being a core requirement of the state grant funding that has now been conditionally awarded.

Formal Objection to Inclusion of 101 N. El Camino Real in BHSA Plan and Objection to Closing Public Comment Period
March 2, 2026

Members of the Behavioral Health Commission (BHC)
San Mateo County

Re: Formal Objection to Inclusion of 101 N. El Camino Real in BHSA Plan and Objection to Closing Public Comment Period

Dear Members of the Behavioral Health Commission,

My name is Eric Isero, DC, QME. I am a longtime resident of San Mateo and write to formally — and with considerable frustration — object to the proposed Behavioral Health Services Act (BHSA) Three- Year Integrated Plan for Fiscal Years 2026–2029, specifically as it includes the proposed 69-bed Horizon Services facility at 101 N. El Camino Real.

I do not raise this objection as an outsider or someone opposed to behavioral health services. I raise it as someone who has lived less than one block from this intersection for over 30 years. I pass by 101 N. El Camino Real four times daily. I know this corner intimately. And I can tell you with confidence: it is the wrong location for a facility of this size and intensity.

The intersection itself presents serious logistical challenges. There is virtually no parking. The surrounding corridor is dense with residences, schools, daycares, and senior living facilities. These are not minor inconveniences to be managed away with a traffic study — they are fundamental incompatibilities that should have triggered serious site scrutiny long before this project was embedded in a countywide plan.

My objection applies directly to the March 4, 2026 “New Business” action items on your agenda, including:

266 of 751

2 • The proposed vote to close the 30-day public comment period on March 5, 2026; and • The proposed vote to submit the BHSA Integrated Plan to the Board of Supervisors.

The draft Plan references the Horizon project (pp. 108 and 125), describing a campus including sobering beds, ASAM 3.2 detox beds with IMS, and ASAM 3.5 residential treatment beds — a comparatively large, high-intensity, 24/7 behavioral health facility proposed within approximately 1,000 feet of schools, daycares, senior living facilities, and established neighborhoods. The following concerns remain wholly unresolved:

3. Unprecedented Scale: At 69 beds, this facility is reportedly far larger than comparable Bay Area facilities and represents a regional outlier in size and service concentration. This demands explanation, not assumption.

4. Site Sensitivity: The immediate proximity to an elementary school and vulnerable populations including daycares, senior living facilities, and high-density residential neighborhoods requires heightened transparency and rigorous analysis — neither of which has been provided.

Closing the public comment period under these conditions would be premature and inconsistent with the spirit of transparent stakeholder engagement required under the Behavioral Health Services Act.

Moreover, moving forward with the Horizon project as currently proposed puts the entire BHSA plan at collective risk of legal challenge. This is not a hypothetical concern — it is a foreseeable consequence of procedural shortcuts on a project of this magnitude.

Accordingly, I respectfully but firmly urge the Commission to consider one or all of the following actions:

ALTERNATIVE ACTION 1:

Vote against closing the public comment period and instead extend it for 180 days to allow for meaningful, site-specific review and community engagement before submitting the Plan to the Board of Supervisors.

ALTERNATIVE ACTION 2:

Proceed with submission of the broader BHSA Integrated Plan for Fiscal Years 2026–29, but only after voting to decouple and exclude the 101 N. El Camino Real Horizon project from the Plan.

In addition to either of the above, I strongly encourage the BHC to establish an Ad Hoc Subcommittee to:
• Assemble and disseminate all project plans and details; • Conduct site-specific review;
• Engage directly impacted stakeholders;
• Evaluate alternative sites;

Subject: Horizon Drug Treatment in San Mteo 101 N. El Camino Real Dear Members of the San Mateo City Council,
I am writing as a neighbor regarding the proposed Horizon detox and treatment facility at 101 N. El Camino Real, being advanced by Horizon and San Mateo County.

Over the past several weeks, the Council has received more than 350 letters from residents expressing concern about this specific location. The volume of correspondence alone shows how seriously the community views this issue.

It appears the Council received early notice from the County sometime in 2025 regarding this proposed project. Despite that early notice, there was no public discussion, community outreach, or notification to residents. I would like to understand why.

Many Councilmembers regularly publish newsletters, attend neighborhood meetings, and provide updates about major developments in the city. Yet this project, which involves a 69-bed high-acuity detox and residential treatment facility funded almost entirely with public funds, was not communicated to residents until February 2026.

The lack of early transparency from the applicant, the County, and City leadership has clearly contributed to the current situation. When a large publicly funded project moves forward without informing the community or engaging local stakeholders, it inevitably undermines public trust. The absence of earlier communication from the City has been a significant shortcoming.

The San Mateo community is compassionate and understands that detox and treatment services are needed. However, residents will not support a site selection process that appears to have occurred without meaningful community engagement, without visible site analysis, and without addressing safety concerns for nearby residents, children, and seniors.

Given the current situation, I respectfully ask the Council to take several immediate steps.

First, agendize a special Council meeting dedicated specifically to the proposed facility at 101 N. El Camino Real so that the issue can be discussed publicly.

Second, send a formal letter to the County and the relevant State grant agency noting that meaningful community engagement did not occur prior to mid-February 2026, despite community outreach being a core expectation of the state grant funding that has been conditionally awarded.

Third, document the sensitive uses surrounding the proposed site. The City should provide a clear inventory of schools, childcare facilities, residential neighborhoods, and senior-serving facilities within at least a 1,000-foot radius so that state and county officials fully understand the context of this location.

269 of 751

2 Finally, request that the County and the State explore an alternative site. A location in a more appropriate setting, such as an industrial or medical zone, would better address safety concerns while still preserving the available funding for treatment services.

Taking these steps would demonstrate that the City of San Mateo takes seriously both the need for treatment services and the responsibility to ensure that projects of this scale are planned transparently and responsibly.

It is also worth noting that 2026 is an election year. Residents are paying close attention to how the Council responds to this issue, and the positions taken here will inevitably influence how the community evaluates its leadership.

I encourage the Council to address these concerns promptly and help guide this project toward a solution that better reflects both community input and responsible planning.

Sincerely,

Eric Isero,

Proposed Horizon Drug Center
My husband and I live at .

We are opposed to the proposed facility at El Camino and El Cerrito for the following reasons.

This facility would be in a very close proximity to Episcopal Day School and several other schools as well as high density apartments, single family homes and retirement communities.

The corner of El Camino and El Cerrito is often congested with traƯic and there are frequent auto accidents.

The safety of individuals walking in the area as well as additional cars parking on DeSabla, Baytree Way would be compromised. It would also attract individuals with alcohol , drug or behavior problems to the area.

WHY, when other facilities are located in non- residential areas and are of a much smaller size, was this location chosen and at a substantial higher cost and size to other facilities.? It is obvious that those involved in this decision gave no thought to the residents, the increased traƯic, cars, police and ambulance activity 24/7 as well as safety issues.

The Palm Avenue facility has only 17 beds and needed police response 33 times in a year. With 69 beds one can only imagine the number of calls that could take place in this proposed location.

The County has not been forthright in their communication with those directly impacted this facility.

There are too many unanswered questions that make one wonder who are the beneﬁciaries of this decision.

We hope that common sense will prevail with regards to this project and a suitable area (non-residential) at less cost to the tax payers will be found.

Thank you,
