Agenda packet — San Mateo City Council, April 15, 2026 (part 2 of 3)

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.

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

300 of 751

2 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.

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,

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 general 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 fund $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.

Thank you,
Yong Kil

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 Elementary, 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.

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

RE: Formal Objection to Inclusion of 101 N. El Camino Real in BHSA Plan and Objection to Closing Public Comment Period
In addition to our community letter. I wanted to share my own thoughts…

While I do recognize the need for such a facility, if I’m being honest, it does not belong where it is proposed. Smack in the middle of single family and multi- family residential, a number of elementary schools, and retirement homes etc…

Because of the nature of operating this facility and its scale at 69 beds…. It belongs adjacent to other public services and away from families that live , work, and pay taxes and elect our officials to protect us
all from the potential harm such a facility brings long term. Sorry if that’s a bit harsh.

Most all want to be compassionate , but also, we need common-sense community planning. This corner and its zoning, when put in place over ½ a century ago or more , did not contemplate this intense, problematic use would ever fall under its scope. The fact they have landed here and have any support at all feels like our community planners are hiding behind outdated zoning and the states mandates for such facilities.

In addition, the intersection of El Cerrito and ECR already exceeds and reasonable persons level of traffic flow, with left hand turn lanes , bus stops, crowing of the street, phone transformers blocking visibility.

The close proximity of the proposed use’s ingress/egress points only add to this issue. The intersections current conditions already creates too many accidents and hazards. The cement Ballards and the number of broker light standards clearly demonstrate the safety issues at hand.

In closing… The County has land, SMC Fair grounds or up by Tunnel Road just to name a few would be appropriate and I would like to believe supported by reasonable community leaders and residents alike.

Thanks for hearing me out..

Dear Members of the Behavioral Health Commission (BHC),

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.

313 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.

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 South Hillsborough Elementary, 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.

I respectfully request the following:

A 60-day extension of the public comment period, which would require voting against closing the comment period

Establishment of an Ad Hoc Subcommittee to engage stakeholders and analyze the site setting

324 of 751

2 Decoupling of 101 N. El Camino Real from the BHSA Integrated Plan for FY 2026-29

Identification of an alternative site that is not directly adjacent to schools, childcare centers, senior facilities, or dense residential neighborhoods

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,
Michelle Knoop

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.

328 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.

Subject: Concerns about proposed Horizon detox and treatment facility 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 mid-February 2026, despite community outreach being a core requirement of the state grant funding that has now been conditionally awarded.

330 of 751

2 3. 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.

Stop the Horizon DETOX Project at 101 N. El Camino Real – Demand Transparency Dear San Mateo City Councilmembers (and/or) 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 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? 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.

Sincerely,
Jennifer Kuo
Hillsborough Resident

Subject: Protesting New Planned Drug Detox Center in San Mateo at the corner of El Camino and El Cerrito

We live in Hillsborough on De Sabla Road. Do NOT locate a Drug Detox Center at 101 N. El Camino Real in San Mateo because it is only blocks away from 3 preschools:

Chai Preschool on Monte Diablo Ave
Little wonders at 225 Tilton Ave
Kidz connection at 137 San Mateo Drive

It is a quarter of a mile from the Hillsborough elementary school and less than 900 feet from St Matthew Catholic elementary school

While it is important to have drug detox centers, they should not be located in residential areas or walking distance from preschools , day care centers or elementary schools for obvious reasons. Patients often try to escape and in a densely populated community such as our area, they could easily hide and be dangerous to residents.

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 to multiple elementary schools, child daycare centers, senior living facilities, and residential neighborhoods, as well as being located at a high traffic volume intersection require heightened transparency and analysis.

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;  Conduct site-specific review;
 Engage directly impacted stakeholders;
 Evaluate alternative sites, including conducting a benefit-cost analysis for each potential site;  Analyze scale, concentration, and compatibility concerns;  Report back with recommendations.

3 The Commission has an opportunity to demonstrate leadership, transparency, and responsiveness, i.e., sound governance. Excluding or pausing this single project does not undermine behavioral health services countywide — it ensures they are implemented responsibly and with community trust.

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.

Many Council members 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:

Finally, it is important to recognize that 2026 is an election year, and Council members will be seeking reelection.

Proposed Horizon Recovery Center at 101 North El Camino Real Dear County Executives-Representatives,

I am a resident of the County (Town of Hillsborough) and an economist with over 35 years of experience in government policy analysis. I have previously communicated my concerns--shared by many County residents--regarding the lack of transparency and community involvement in the process that led to the proposed location of the Horizon Recovery Center at 101 North El Camino Real. Based on what I have heard at the various events to date, I would like to emphasize several points:

 Sound government decision-making requires weighing the costs and benefits of a proposed action.
 The question at issue here is not whether there should be a treatment center, but instead where the treatment center should be located.
 When deciding where to locate a facility such as this, the cost-benefit analysis simplifies to identifying the location that imposes the least costs on the community. This is because the facility's benefits (i.e., treatment for those in need in this case) will be realized regardless of location and therefore do not favor one location over another.  In contrast to the benefits, the costs are not the same across all potential locations. Potential locations differ in their surroundings (proximity of schools and elderly living communities; residential versus commercial makeup; traffic patterns; etc.). A location's surroundings have profound implications for the costs (safety, crime, traffic, noise, etc.) that would be imposed on the community. Some locations clearly would be more costly than others.  A sound decision about location therefore requires (1) identifying potential locations and (2) in- depth analysis and comparison of the costs that each potential location would impose on the community.
 There is no indication that such an analysis has been conducted here, which explains why so many residents are concerned about the lack of transparency and community engagement. Allowing the location of the facility at 101 North El Camino Real without fully considering all potential locations and their associated costs would represent a serious failure of governmental responsibility.
 Horizon's incentives are not aligned with those of the community and therefore you, as representatives of the community, should not delegate the location decision to Horizon.

Left to
its own devices, Horizon has no incentive to choose the location that minimizes the costs to the community because Horizon would not bear those costs. In fact, Horizon would not even voluntarily engage in the task of analyzing the costs to the community because that would require time and expenditures that Horizon would prefer to avoid. This is the case despite Horizon's "non-profit" status.

374 of 751

2 In sum, I urge you not to delegate this location decision to Horizon, but instead to thoroughly analyze potential locations and their associated costs—including by seeking community engagement—and to locate the facility where it will minimize costs to the community.

Sincerely,

Gregory K. Leonard

Dear Members of the Behavioral Health Commission,

As a current parent at Episcopal Day 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.

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:

Thank you very much for your consideraƟon.

Sincerely,
Theresa Liu

Do Not Advance the BHSA Plan With 101 N. El Camino Real Included Dear Members of the Behavioral Health Commission,
I am a San Mateo resident, former Belmont Planning Commissioner, and board member of a nearby neighborhood association writing to formally object to advancing the BHSA Three- Year Integrated Plan as long as it includes the proposed 69-bed Horizon facility at 101 N. El Camino Real.

This is not a minor program addition. It is a large-scale, 24/7 campus including sobering beds, detox (ASAM 3.2 with IMS), and residential treatment (ASAM 3.5) — proposed in a dense residential corridor within roughly 1,000 feet of an elementary school, daycares, senior living, and established neighborhoods.

Before closing public comment and forwarding this Plan to the Board of Supervisors, several issues remain unresolved:
 Insufficient public disclosure of site design, operations, safety protocols, intake standards, transportation management, and neighborhood mitigation.  No meaningful, site-specific community engagement with directly impacted residents, schools, and businesses.
 Unusual scale and intensity relative to comparable regional facilities.  Highly sensitive location requiring heightened transparency and review.

Closing the comment period under these conditions would be premature and inconsistent with the spirit of the BHSA.

I urge the Commission to take one of the following actions:

1. Extend the public comment period to allow for meaningful, location-specific review; or

2. Decouple and exclude the 101 N. El Camino Real project from the BHSA Plan before forwarding
it to the Board.

A project of this magnitude warrants separate, transparent evaluation — potentially through an Ad Hoc Subcommittee under Section 6.4 of your bylaws.

Please enter this letter into the public record for the March 4, 2026 meeting.

Lower-Risk, Faster Alternatives Deserve Your Support - Not 101 El Camino Dear Supervisor Corzo,
I share your desire for a much-needed sobering center for San Mateo County. I fully support the goal of expanding access to behavioral health and recovery services.

I’m writing to respectfully urge reconsideration of the proposed location at 101 N. El Camino Real in favor of alternatives that can achieve the same public health outcomes with lower community impact, reduced risk, and a higher likelihood of timely implementation.

I understand the concern that state funding (approximately $22M) has been tied to the current site and may be diƯicult to redirect. However, proceeding with a location that is already generating signiﬁcant opposition introduces a diƯerent - and potentially greater - risk: delay, reputational strain, and possible project disruption. In that context, it is worth engaging the state proactively to explore whether ﬂexibility exists, particularly if the County can present a clearly superior site from an implementation standpoint.

Two such alternatives stand out:
 The San Mateo County Youth Services Center oƯers a large, underutilized (less than 20% utilized), controlled campus already designed for supervised care. Its physical separation and existing infrastructure make it well-suited for this type of program with signiﬁcantly less neighborhood impact.
 StarVista presents an opportunity for faster deployment. As an established behavioral health provider, reopening and expanding this site (adjoining properties are available) could deliver near- term capacity with far less controversy and a more straightforward operational model.

This is not a question of whether to move forward - it is about ensuring that the County selects a site that minimizes risk and maximizes the likelihood of success. A centrally located, highly visible corridor like El Camino Real may appear advantageous on paper, but in practice it increases the probability of ongoing conﬂict and delay. A more suitable site can better serve both clients and the broader community.

If the concern is timing, one potential approach would be to pursue a near-term solution through StarVista while continuing to evaluate longer-term capacity options such as YSC. This allows the County to act quickly without committing to a path that may prove more diƯicult to execute. This can also allow for increased bed count if the County determines additional need.

I respectfully ask that you and your colleagues take a second look at these alternatives before ﬁnalizing the current site. Evaluating lower-risk options could ultimately save time, reduce friction, and lead to a more successful outcome for everyone involved.

Thank you for your time and consideration.

Sincerely,

Subject: 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 I am writing 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 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 references the Horizon project (pp. 108 and 125) and describes a campus that includes sobering beds, ASAM 3.2 detox beds with IMS, and ASAM 3.5 residential treatment beds. This is a large, high-intensity, 24/7 behavioral health facility proposed in a dense residential corridor, located approximately 1,000 feet from an elementary school, daycares, senior living facilities, and established neighborhoods.

The following concerns remain unresolved:

Insufficient Public Information
There has been minimal disclosure of detailed site plans, operational protocols, security measures, intake criteria, discharge procedures, transportation management, staffing ratios, or neighborhood mitigation strategies. The community has not been provided with enough information to fully understand the day-to-day impact of this facility.

Lack of Meaningful, Site-Specific Community Engagement
There has been no comprehensive, location-focused engagement process with directly impacted residents, schools, childcare providers, senior communities, and local businesses prior to inclusion of this project in the Plan.

Unprecedented Scale
At 69 beds, this facility is significantly larger than many comparable behavioral health facilities in the Bay Area and represents an unusual concentration of high-acuity services in a single neighborhood setting.

402 of 751

2 Site Sensitivity
The immediate proximity — less than 1,000 feet — to an elementary school and other vulnerable populations warrants heightened transparency, careful planning, and detailed impact analysis.

Environmental Impacts and Risks
In addition to operational and safety concerns, the environmental implications of this project have not been adequately addressed. A 24/7, high-intensity treatment facility of this size may result in:
 Increased traffic congestion, vehicle emissions, and noise in a residential corridor;  Greater demand for water, sewer, and waste management systems;  Medical and hazardous waste generation requires strict handling protocols.  Potential air quality impacts from emergency transport activity and service vehicles;  Light and noise pollution are affecting nearby homes, schools, and senior living facilities.

Without a thorough environmental review and transparent disclosure of mitigation measures, advancing this project raises legitimate concerns about long-term neighborhood compatibility and environmental sustainability.

Closing the public comment period under these circumstances would be premature and inconsistent with the principles of transparency and meaningful stakeholder engagement envisioned under the Behavioral Health Services Act.

Furthermore, moving forward with the BHSA Plan for 2026–2029 in its current form — without separating and excluding the Horizon project at 101 N. El Camino Real — places the broader Plan at risk of legal challenge. A single controversial and insufficiently vetted project should not jeopardize critical countywide behavioral health funding and initiatives.

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 genuine community engagement prior to submitting the Plan to the Board of Supervisors. This would include voting against submission of the Plan at this time.

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 pursuant to Section 6.4 of the BHC Bylaws to:
 Assemble and publicly disseminate all project plans and operational details;  Conduct a site-specific review;
 Engage directly impacted stakeholders;
 Evaluate alternative sites;
 Analyze scale, service concentration, environmental impacts, and neighborhood compatibility;  Report back with formal recommendations.

403 of 751

3 A project of this magnitude warrants a separate, transparent review rather than being embedded within a comprehensive countywide plan without focused scrutiny.

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

Pausing or excluding this single project does not undermine countywide behavioral health services — it ensures they are implemented responsibly, sustainably, 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,
Yulia Lopatyuk

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 Episcopal Day School, I am submitting this formal objection to the BHSA Three-Year Integrated Plan during the public comment period, ahead of the March 4 meeting where Action Item 1 would close that period.

My concern centers on the proposed 69-bed Horizon Services facility at 101 N. El Camino Real (referenced on pages 108 and 125 of the plan). A substance use campus roughly 3x the Bay Area average in size, with around-the-clock operations, should not be sited within 1,000 feet of an elementary school, daycare facilities, senior living communities, and family neighborhoods — particularly when no site- specific community engagement process has taken place with the people who would be most directly affected.

I understand and support the need for behavioral health infrastructure in our community. But the scale and intensity of this project demand a process that matches. I'd ask the Commission to consider the following:

1. Vote against closing the comment period on March 4 and instead grant a 60-day extension so affected community members have adequate time to review and respond.

2. Establish an Ad Hoc Subcommittee — as provided for under Section 6.4 of the BHC Bylaws — to conduct a thorough, site-specific stakeholder review of the Horizon Center proposal.

3. Decouple the 101 N. El Camino Real project from the FY 2026–29 Integrated Plan until that review is complete.

4. Explore alternative locations that do not place a facility of this intensity directly adjacent to schools, childcare centers, senior housing, and dense residential areas.

The Commission's own Integrated Plan identifies Community Program Planning and Data Review as core pillars. A project of this magnitude deserves a process that lives up to those principles — one that is transparent, data-informed, and inclusive of the community it would impact most. The stakes for our kids and our neighborhood are too high to rush this through.

Thank you for your time and 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 regarding the proposed Horizon detox and treatment facility at 101 N El Camino Real, which is being advanced by Horizon and San Mateo County.

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.

The San Mateo community is compassionate and understands that detox and treatment services are necessary.

However, residents will not accept a site selection process that appears to have been driven by secrecy, incomplete information, no community engagement, and zero visible site analysis that disregards the safety concerns of our children, the elderly, and the general population.

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.

3. 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.

4. Request to explore an alternative site
The Council should request that the County and the State allow the proposed facility to be relocated to a more appropriate

411 of 751

2 setting - such as an industrial or medical zone - where safety concerns for vulnerable populations and residents can be minimized while preserving the available state funding for treatment services.

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,
Joanne Lue

Subject: Stop the Horizon DETOX Project at 101 N. El Camino Real – Demand Transparency Dear San Mateo City Councilmembers and San Mateo County Supervisors,

Thank you for your ongoing service to our community. I am writing as a concerned San Mateo resident regarding the proposed Horizon DETOX facility at 101 North El Camino Real. My main concern is the lack of transparency and meaningful community engagement surrounding this project, particularly given its proximity—less than 1,000 feet— to an elementary school, senior living facility, childcare facility and the Child and Family Counseling Center located directly across the street at 120 N El Camino Real..

I appreciate your attention to community voices and recognize the many factors and complexities you must weigh in city and county decision-making. Like many in our community, I only became aware of the Horizon DETOX proposal within the past few weeks, although it has evidently been progressing through County processes for several months. This communication gap has left residents without critical information about how and why the project advanced to this stage and what precautions will be taken to ensure public safety for the neighborhood in general and specifically at the site itself.

To ensure trust and transparency, I respectfully request that the County and City pause and reconsider this project until the community receives full disclosure addressing several fundamental questions:
• How and when did the Horizon DETOX project originate, and who initiated it? • What roles 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 was this site selected? • Why was the project referenced only in two brief paragraphs within the County’s 252-page BHSA plan?

Given the significance of this proposal and its impact on our residential neighborhood, I respectfully urge the County and City to schedule a public meeting at the earliest opportunity—ideally within the next month— to address
these questions and engage directly with residents. I am eager to participate in such a forum and support a transparent, collaborative process.

Until this information is fully disclosed and discussed publicly, I respectfully request that the project be paused and reconsidered. Thank you for your time and attention to this matter. I look forward to your response and to participating in future discussions to ensure our community’s voice is heard.

Sincerely,

Amy MacDonald

Halt and Re-evaluate Horizon DETOX at 101 N. El Camino Real Dear San Mateo City Council members and San Mateo County Supervisors, I am a San Mateo resident writing to express serious concern about the proposed Horizon DETOX facility at 101 North El Camino Real.

Like many neighbors, I was only notified of this project recently, even though it appears to have been moving through County channels for months. Our community deserves a clear understanding of how this project reached this stage without robust public notice, meaningful outreach, or transparency.

I urgently ask that the City and County stop and reconsider this project’s location as residents have not receive full disclosure, adequate information and few to no answers to important questions, including:
 When and how did this proposal begin, and who brought it forward?  What involvement did City and County staff or elected officials have in endorsing or advancing it?

 What evaluations have been completed regarding traffic impacts, neighborhood safety, and land- use compatibility?
 What other potential sites were considered, and why was this location selected over alternatives as there are many locations currently on the market in non-residential areas and closer to hospitals and key transportation hubs (such as right across from Peninsula Hospital)? This building was never even on the market, how did Horizon and the county even get this location on their radar!
 Why does the County’s 252-page BHSA plan mention this project only briefly, in two short paragraphs?
 What security measures will be put into place to ensure no impact to the surrounding residential and educational community
A facility of this scale should not proceed in a residential area—especially within less than 1,000 feet of an elementary school and a quarter mile of other schools — without full transparency, genuine community participation, and a publicly explained decision-making process.

Until these issues are addressed openly and thoroughly, I respectfully request that the Horizon DETOX project be halted and reevaluated.

Dear Members of the Behavioral Health Commission (BHC),

As a co-owner of 15 El Cerrito, San Mateo, I am writing 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.

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.

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.

424 of 751

2 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:

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,

Stop the Horizon DETOX Project at 101 N. El Camino Real – Demand Transparency March 14, 2026
Dear San Mateo City Councilmembers and San Mateo County Supervisors, I am writing to you today as a deeply concerned property owner in San Mateo regarding the proposed Horizon DETOX facility at 101 North El Camino Real. While I recognize and appreciate the County’s ongoing commitment to expanding access to behavioral health and substance use treatment services, I must respectfully but firmly raise a series of critical concerns about the process by which this proposal has advanced, and the manner in which it has been presented — or rather, not presented — to the community most directly affected by it.

Like many community members, I only became aware of this project recently, despite the fact that it has apparently been progressing through County planning and approval processes for several months. This is deeply troubling. A facility of this scope, proposed for placement within a residential neighborhood and in close proximity to an elementary school, warrants robust public engagement from the very outset — not a brief, buried reference in two paragraphs of a 252-page County Behavioral Health Services Act (BHSA) plan. The lack of proactive, transparent communication with the surrounding community is not merely an oversight; it raises fundamental questions about accountability and the integrity of the decision-making process.

I respectfully, but urgently, request that the County and City jointly pause and reconsider this project until the community has received full, meaningful disclosure and satisfactory answers to the following foundational questions:
• How and when did this project originate, and who were the initiating parties? Was this proposal brought forward by County staff, an outside vendor, or a combination of both? What financial arrangements, if any, have already been established?
• What specific role did County and City officials play in supporting, advancing, or approving this proposal? Were elected officials briefed, and if so, at what stage? • What impact analyses have been conducted with respect to traffic, parking, neighborhood safety, and land-use compatibility? Have these analyses been made available for public review, and if not, why not?

427 of 751

2 • What alternative locations were evaluated during the site selection process, and on what basis were they rejected in favor of 101 North El Camino Real? Was proximity to a residential area and an elementary school factored into that evaluation? • Why was this project referenced in only two brief paragraphs within the County’s 252-page BHSA plan, rather than being presented as a discrete agenda item subject to independent public notice and comment?
Of particular concern is the facility’s proposed location less than 1,000 feet from an elementary school. Regardless of one’s views on the merits of detox and treatment facilities in general, the placement of such a facility in such close proximity to a school serving young children demands a heightened standard of scrutiny, community input, and justification. Parents, educators, and residents in the immediate area deserve to understand precisely what operational safeguards will be in place, what the expected patient population will look like, and how the facility will interface with the surrounding neighborhood on a day-to-day basis.

Beyond the specifics of this particular project, this situation reflects a broader concern about how the County and City engage with residents on consequential land-use and public health decisions. Meaningful community engagement is not simply a procedural formality — it is a cornerstone of democratic governance and public trust. When residents learn about significant infrastructure proposals through informal channels rather than official notice, confidence in local government is eroded. I urge you to use this moment as an opportunity to reaffirm your commitment to genuine transparency and participatory decision-making.

Until the above questions have been thoroughly answered, the relevant analyses made publicly available, and a genuine community engagement process conducted — one that allows the affected community adequate time and opportunity to review, respond, and participate — I respectfully request that all further advancement of this project be halted.

The bar for proceeding should be full transparency and demonstrated community support, not the absence of organized opposition.

Thank you for your time, your service to our community, and your attention to this matter. I trust that you will take these concerns seriously and respond in a manner befitting the public trust you have been elected and appointed to uphold.

Respectfully,
Kathryn MacDonald

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 town 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 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 following concerns remain unresolved:

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.

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.

Dear San Mateo City Council Members,
I am a concerned San Mateo resident regarding the proposed Horizon DETOX facility at 101 North El Camino Real.

I recently learned about this project despite the fact that it has been progressing through the City processes for months. I, and others, deserve to know how and why this proposal advanced without community engagement or transparency.

I am requesting that the City (and County) pause and reconsider this project. The following questions must be answered and the project must be approved by the majority of citizens prior to this project moving forward:
• 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 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.

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 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.

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.

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

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?

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 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.

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 member of the Episcopal Church 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."

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.

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. 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.

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.

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.

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

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

Objection to large drug rehab center proposal at 101 N. El Camino Real

Dear Members of the Behavioral Health Commission (BHC),

I am a long-time resident of San Mateo County. I am just hearing of the proposal to open a large-scale drug rehab center down the street from several preschool and elementary/middle schools. I am strongly opposed to this proposal and ask that a more appropriate location be considered.

If you look at Yelp reviews of the Cherry Hill Detox / Rehabilitation Center in San Leandro, which is a comparable size and management, you will read that they release people from their center into the streets at all hours. This would mean high numbers of drug-addicted people released in a neighborhood of schools and children.

I drove around the proposed location yesterday, and within 3 blocks saw several groups of children. One was a group of 3 girls (approximately 11-13 years old) walking alone, another was two approximately 10- 12 year old boys walking alone. There were also two play areas with larger groups of kids playing outside, and two ~3 year olds playing outside near South preschool while their mothers talked nearby. My own children used to bike alone on El Cerrito near the proposed site regularly when they were younger. This is not an appropriate area for a large drug detox and rehab center.

I ask that you consider the safety and impact to the children of San Mateo County when determining the location of this center.

Best regards,
Laura Miller

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 the manager of the Versailles senior residential community located at 10 Crystal Springs Rd, San Mateo. Our community is comprised of 60 independent senior living condominiums. Very few of our residents seem to be aware of the proposed new Horizon Services facility which is 1 block away from our community. I am writing 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.

479 of 751

2 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.

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.

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

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.

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 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.

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.

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:

493 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 careful consideration.

Sincerely,
Melanie Myers

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 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 following concerns remain unresolved:

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.

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.

495 of 751

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

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.

Re: Update and Invitation for Proposed Horizon Project
Dear Supervisors,

I hope the event tomorrow will a proper Q&A were residents can learn more about this project.

We have simple questions:

-what will it take to move the Detox center to another location? -if you insist on this location how will you ensure safety to residents and nearby schools? Is the county paying for more police/security presence?
-what due diligence went into the site location?

The residents feel the country supervisors have let the resident down by not informing us of this project in a timely manner, and have not provided an opportunity to answer our basic questions.

The issue is transparency, responsible site selection, and a public process that respects the community affected by the decision.

Thank you,

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 in February 2026. 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 this project until the community receives full disclosure and answers to several questions:
• 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? • 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?

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.

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.

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

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.

March 16, 2026
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.

Much has been written and discussed online regarding this project. Clearly, there are strong opinions on both sides. As San Mateo residents for 30+ years we are concerned by this project.

While there is much disagreement regarding location there seems to be common ground regarding the need for drug/alcohol and mental health treatment for those in need. If treatment facilities are to be found in San Mateo County then it is the responsibility of San Mateo County officials to properly evaluate the scope of services to be provided as well as the location of where such services are to be located only after a thorough assessment which weighs seriously the input of its citizenry. The needs of San Mateo residents, particularly those most directly impacted (e.g. neighbors in proximity) should be given the highest priority. Paramount consideration should be given to personal safety for us, our families and others (e.g. school children, seniors etc…) whether perceived or otherwise. In addition, the potential negative impact on one’s real estate should be an important element of the assessment process. If one owns property nearby, are they at risk of a diminished investment value because a treatment center is nearby? One would think a prospective purchaser might be interested in this information. Kindly note the comment on Next Door by one resident of the Gramercy Mounds who stated that they never would have purchased their home had they known this project might come to fruition. We suspect more than a few may share that opinion – particularly current property owners who may one day wish to sell.

The process around this project requires complete transparency and input from concerned San Mateo citizens (on both sides of the issue) before any further steps are taken.

Sincerely,

James & Kathleen Paver

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, within walking distance of the proposed Horizons Services facility, and write to formally object to the proposed Behavioral Health Services Act (BHSA) Three-Year Integrated Plan for Fiscal Years 2026-2029, speci fically 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.

2 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,
Nancy Paynter

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 Grandparent at South Hillsborough 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.

I respectfully request the following:

- A 60-day extension of the public comment period, which would require voting against closing the comment period
- Establishment of an Ad Hoc Subcommittee to engage stakeholders and analyze the site setting
- Decoupling of 101 N. El Camino Real from the BHSA Integrated Plan for FY 2026-29 - Identification of an alternative site that is not directly adjacent to schools, childcare centers, senior facilities, or dense residential neighborhoods

Pursuant to Section 6.4 of the BHC Bylaws, I formally request that the Behavioral Health Commission establish an Ad Hoc Subcommittee 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.

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. El Camino Real.

As a psychologist in the area, I understand the beneﬁts of such a program for rehabilitaƟon, and I also understand the safety concerns that will inevitably bring disrupƟon, danger and exposure to dysregulated and harmful scenes to the children in the residenƟal area, as well as the elementary close by. Many of those children walk to and from school the same street of the proposed locaƟon for this center.

3. 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.

563 of 751

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

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

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 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,

Cc: City Council (San Mateo); [email protected]; Alex Khojikian Subject: RE: Questions Regarding Proposed Sobering Facility at 101 N El Camino Real Hello Christina,

Thank you for your prompt response.

My main concerns are less about the overnight sobering component and more about the long-term addiction rehabilitation component and overall scale. This proposal is for a 69-bed facility with a significantly expanded scope, not simply a replacement for the prior 14-bed sobering center.

I also struggle with the site-selection rationale that has been shared by you. If proximity to emergency services is a key criterion, Mills-Peninsula is in Burlingame, and the San Mateo campus does not appear to offer the same level of emergency services.

The San Mateo PD is on the opposite end of the city, which may make rapid responses more challenging. In addition, the proposed site at 101 N El Camino Real is more than 4 miles from Mills-Peninsula. A radius of that size would likely have allowed the County and provider to identify a more suitable location that is not immediately adjacent to so many sensitive uses and high-traffic community assets, including:
 Schools, including pre-K and kindergarten programs
 Multiple daycares
 Senior and elder-care facilities
 The main San Mateo library
 The Mickelson Center
 A tremendous number of residential neighborhoods that families choose specifically for safety and quality of life
 Downtown San Mateo
 The El Camino Real corridor, where the City is planning for additional multi-family housing over time
San Mateo is already working to catch up to peer cities on housing production and thoughtful redevelopment. Siting a large facility of this nature in such a central and sensitive location, without clear and enforceable operational safeguards, risks undermining that progress and creating avoidable concerns for families, seniors, and the broader community.

Finally, the outreach to date feels minimal and late in the process - “meeting the minimum legal requirement” is not the same as meaningful community engagement. For a county-sponsored, taxpayer- funded project, residents deserve transparency on the site search process, the alternatives considered, and the concrete operational protections that will be in place. Many in the community feel they are being looped in only after key decisions are effectively made.

We can acknowledge that sobering and treatment capacity are needed while still insisting that site selection and operating conditions be handled with care, transparency, and in conjunction with the desires of the local community.

Are alternative locations still being considered?

Best,
Kolja

Hi Kolja,

Thank you for reaching out and for sharing your questions regarding the proposed sobering and addiction treatment facility at 101 N. El Camino Real. On behalf of Supervisor Corzo, I want to thank you for your engagement and share additional context ahead of Thursday’s meeting.

581 of 751

2 San Mateo County lost its 14-bed sobering center in May 2025, creating a significant gap in care. In response, the County has partnered with Horizon Services to restore these services through the proposed Horizon Recovery Center—an integrated, 24/7 campus offering sobering, withdrawal support, and residential treatment.

The site was identified in part due to its proximity to healthcare partners, including Mills Hospital, and its ability to support a continuum of care in one location. The model includes 24/7 clinical staffing, on-site security, structured intake and discharge to support both patient and neighborhood safety.

The County’s $2 million contribution comes from opioid settlement funds and helps leverage more than $20 million in state funding to rebuild critical behavioral health infrastructure. Once operational, the program will include oversight, performance monitoring, and a process for community feedback.

We recognize the importance of community input and look forward to continuing the conversation at Thursday’s Zoom.

Sincerely,

CAUTION: This email originated from outside of San Mateo County. Unless you recognize the sender's email address and know the content is safe, do not click links, open attachments or reply.

Hello Noelia,

I hope you are well.

I am writing regarding the county-sponsored sobering and long-term addiction treatment facility proposed by Horizon at 101 N El Camino Real in San Mateo. I understand the County is playing a key role in this effort, and I would appreciate clarity on how this site was selected and what safeguards are being required.

Specifically, could you please share:
 What was the County’s role in identifying and selecting 101 N El Camino Real for this use (site search process, criteria, alternatives considered)?
 What operational model is being proposed (hours, capacity, services provided, expected length of stay, intake/discharge process)?
 What security and supervision requirements will be in place (on-site staffing levels, 24/7 coverage, coordination protocols with SMPD/EMS)?
 What neighborhood-impact mitigations are planned (loitering prevention, patient transportation plans, behavioral standards, escalation procedures)?
 What oversight and accountability mechanisms will apply once the facility is operating (performance metrics, complaint process, corrective actions, renewal/review triggers)? The location is in close proximity to multiple schools and childcare providers, senior-serving facilities, the main library, downtown, and several surrounding residential neighborhoods. Even for residents who support expanded treatment capacity in principle, the location and operational details here raise serious community-safety and compatibility concerns.

3 The applicant’s outreach appears to have begun only recently, and many neighbors feel they are being brought into the process late - especially when the County was actively involved. Any information you can share ahead of Thursday’s community Zoom would be greatly appreciated.

Subject: Request for Agenda Item & Summary of the Addicition Rehabilitation Community Meeting
Attachments: meeting_saved_new_chat.txt

Good morning City Council,

As you may be aware, the applicant for the proposed sobering and long-term addiction rehabilitation facility at 101 N El Camino Real held its first legally required community meeting yesterday evening.

Alex and Lisa were both in attendance.

I respectfully request that the Council consider agendizing this item for discussion at an upcoming meeting. I understand that the City’s jurisdiction over this project may be limited due to state law.

However, there is significant value in providing a public forum where the project can be discussed in a local setting, City staff and the City Attorney can clearly outline the legal constraints involved, and community members have an opportunity to be heard.

Approximately 80 residents attended last night’s meeting. While many acknowledged the importance of providing services for individuals struggling with addiction, there was broad concern about the specific location selected. To date, I am not aware of any attendees of the community who expressed support for placing a facility of this scale at this particular site. The County run process has left many residents feeling that the project is being advanced without meaningful local engagement.

If the Council does decide to agendize this item, I would strongly encourage inviting representatives from the County and the project applicant to participate in the discussion.

Please see below the summary of the questions posed by the community last night - the full chat transcript of the meeting is attached for reference.

Thank you for your consideration.

Executive Summary of Community Questions and
Concerns

Community feedback focused overwhelmingly on location, safety, process transparency, and scale rather than opposition to treatment services themselves. Participants repeatedly stated they support addiction and mental health services in principle, but strongly object to the proposed siting in a dense residential neighborhood near schools, daycare centers, and senior facilities.

Concerns can be grouped into the following categories:

 Site selection and proximity to schools
 Safety, security, and operational procedures
 Parking, traffic, and infrastructure impacts
 Patient population and program scope

Formal Objection to Horizon Proposal - 101 N El Camino Real in BHSA 2026-2029 Plan Dear Members of the Behavioral Health Commission,

I am a resident of the City of San Mateo and a parent at Episcopal Day School. I write during the 30-day public comment period to formally object to the Behavioral Health Services Act (BHSA) Three-Year Integrated Plan for Fiscal Years 2026-2029 as it relates to the proposed funding and development of the Horizon Services facility at 101 North El Camino Real.

This objection specifically concerns the March 4, 2026 agenda item to close the public comment period and to advance the Integrated Plan to the Board of Supervisors.

The draft Plan explicitly references the proposed 69-bed SUD Campus by Horizon Services (pp. 108 and 125), describing a facility that includes sobering beds, ASAM 3.2 detox beds with IMS, and ASAM 3.5 residential treatment beds. This represents a high-intensity, 24-7 behavioral health facility of a scale that appears to be a regional outlier. The facility would be one of the largest of its kind in Northern California.

While expanding treatment capacity is a legitimate public policy objective, the scale, siting, and process surrounding this project raise serious concerns.

Site Sensitivity and Proximity to Vulnerable Populations

The proposed location sits within less than 1,000 feet of multiple sensitive uses, including elementary schools, childcare centers, senior living facilities, public library facilities, and established residential neighborhoods. The Episcopal Day School is
within roughly 800 feet. Several childcare providers are even closer.

Pending state legislation SB 1060 proposes a 1,000-foot buffer between high-intensity treatment facilities and schools or daycare centers. Whether enacted or not, it reflects a growing statewide recognition that siting standards matter, particularly for facilities operating 24- 7 with sobering intake and
potential law enforcement drop-offs. Advancing a project that would fall within the buffer contemplated by pending legislation creates foreseeable policy conflict and long-term instability.

3 Emergency Services and Public Safety Considerations

The justification for this site has included proximity to emergency services. However, the nearest full- service hospitals capable of handling complex medical emergencies are approximately four miles away in either direction. The San Mateo Police Department is approximately 3.5 miles from the site. For a 24-7 sobering center and detox facility serving acute cases, distance to emergency and law enforcement response capacity should be carefully analyzed and publicly documented.

Questions Regarding Site Selection

Public statements attributed to Horizon leadership suggest that this location was not necessarily their preferred or optimal site. If this was not the operator’s most desired location, the Commission should ask why this specific parcel was selected and whether it was driven primarily by property availability or funding mechanics rather than comprehensive siting criteria.

Was a formal Site Compatibility and Alternative Site Analysis completed? If so:

 On what date was it completed?
 What criteria were used?
 What alternative sites were evaluated?
 Please provide the full analysis for public review.

If no such analysis was conducted, that omission alone warrants delaying advancement of the Plan as it relates to this site.

Lack of Meaningful Community Engagement

Equally troubling is the absence of meaningful community engagement.

The applicant and the County have failed to conduct robust, site-specific outreach. Holding a single informational call less than 2 weeks ago and merely notifying property owners within a 1,000-foot radius is not sufficient for a County-sponsored project of this magnitude. This project is embedded within the County’s Behavioral Health Services planning framework and proposes to use substantial taxpayer funding. Schools, directly impacted families, senior communities, local businesses, and residents beyond an arbitrary radius should have been engaged early and transparently before this project was incorporated into a three-year funding plan.

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

Accordingly, I respectfully request that the Commission consider the following actions:

592 of 751

4 1. Vote against closing the public comment period and extend it by at least 60 days to allow meaningful, site-specific review and community engagement.

2. Establish an Ad Hoc Subcommittee pursuant to Section 6.4 of the BHC Bylaws to assemble and disseminate all project materials, conduct a data-driven site compatibility analysis, engage directly impacted stakeholders, evaluate alternative sites, and report back with recommendations.

3. Decouple and exclude 101 N. El Camino Real from the BHSA Integrated Plan for FY 2026-2029.

4. Identify and evaluate alternative sites that are not directly adjacent to schools, childcare centers, senior living facilities, or dense residential neighborhoods.

5. Publicly release any Site Compatibility and Alternative Site Analysis that has been conducted.

The Integrated Plan lists Community Program Planning and Data Review as core pillars. A project of this magnitude warrants exactly that - a transparent, data-driven, and site-specific review process before public funding is advanced.

I respectfully request that this letter be entered into the public record for the March 4, 2026 meeting.

Thank you for your consideration.

Sincerely,

Kolja Schluetter

A group of residents opposing the proposed Horizon treatment facility at 101 N El Camino Real has received a letter of support for the project issued by San Mateo County Behavioral Health and Recovery Services (BHRS), dated October 22, 2025.

Please see the attached letter. This document is part of the grant application process and is intended to certify community and stakeholder support and engagement.

In the letter, BHRS Director Jei Africa states:
“This project has broad support from behavioral health and law enforcement stakeholders, as well as City and County officials, because of the low-barrier, open-access model[…]”

We are seeking clarification on this statement.

Specifically, on what basis is the City of San Mateo being represented as a supporting stakeholder? To our knowledge, there has been no public outreach, formal discussion, or official action by the City indicating support for this project neither now nor at any point before the issuance of the letter on October 22nd 2025.

Given the significance of this representation in a state funding application process, we respectfully request clarification as to whether the City has formally or informally communicated support for this project, and if so, through what process.

If this statement does not accurately reflect the City’s official position, we would respectfully request that the City take appropriate steps to correct the record with all relevant parties, including the County, BHRS, and the applicable state funding agency.

Thank you for your prompt attention to this matter.

Best regards, Kolja Schluetter

Subject: March 24 Meeting Format, Operator Concerns, and Grant Compliance - 101 N. El Camino Real
Dear Supervisors and Mr. Callagy,

I am a San Mateo resident writing regarding the upcoming March 24 “community meeting” on the proposed detox facility at 101 N. El Camino Real.

I understand that the meeting is being structured around small breakout groups of 8–10 people, each led by a Horizon/County-appointed facilitator. That is not what was communicated to the community, and frankly, it falls short of what this situation requires. This type of format would have been acceptable in summer of 2025 when this project was first picked up.

This meeting format fragments the discussion, limits transparency, and prevents a shared understanding of the facts. It restricts the ability for residents to hear each other’s concerns or arguments for the project, ask follow-up questions in real time, and hold project sponsors accountable in an open setting.

For a project of this scale, sensitivity, and public impact, anything short of a full-room, open Q&A is inadequate.

The community deserves a transparent, collective dialogue where everyone has access to the same information and where difficult questions can be addressed publicly, not filtered through small-group facilitation.

It is equally important that you, as Supervisors, hear these concerns firsthand and without mediation. I would appreciate confirmation that you will attend the meeting on the 24th and participate in an observatory role - while Horizon and Supervisor Corzo owe answers to the community.

Separately, I remain deeply concerned about Horizon as the proposed operator.

Horizon has, to date, been highly opaque about its plans for this project. There has been no meaningful community and local stakeholder engagement, and very limited transparency around the actual operational model, patient profiles, or site selection and management approach. This lack of openness is deeply concerning given the scale and sensitivity of the proposed facility.

Horizon currently operates a 22-bed detox facility in an industrial tract of San Mateo at 2251 Palm Avenue (License #410003AN). That license was placed under a Temporary Suspension Order (TSO) by the California Department of Health Care Services on May 22, 2024, and is still to date operating under probationary status. In addition, public records indicate that the license expiration date has passed as of February 28, 2026.

596 of 751

2 597 of 751

3 Given this track record, it is difficult to understand how Horizon is being considered to operate a significantly larger and more complex facility - roughly three times the size - particularly when their existing operation has already faced serious regulatory action.

This raises fundamental questions about operational capability, regulatory compliance, and overall project integrity. Before moving forward, the community deserves clear and transparent answers from both the Supervisor Corzo and Horizon as to why this operator is considered qualified and whether the current project structure is even compliant with state funding requirements.

I look forward to your response and to engaging directly on these issues on March 24th.

Sincerely,
Kolja Schluetter

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 children currently attend 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. Specifically, I object to Action Item 1 on the March 4th, 2026 agenda to "close the comment period."

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.

Please consider:
- 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

Dear San Mateo City Council Members,

I am writing as a concerned constituent, San Mateo County resident and daughter of a resident of , 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 general 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

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 . 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 greatly concerned about this project. We would appreciate public officials finding a more appropriate location for the Center.

Thank you for your attention.

Best regards,
Carol Sexton and Paul George

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

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:

Subject: Opposition to Proposed Drug Rehab Facility at 101 N. El Camino Real, San Mateo Dear County Executive Officer, Members of the Board of Supervisors, and Relevant County Officials, and Others To Whom It May Concern,
I am writing as a concerned San Mateo resident to formally express my opposition to the proposed Horizon drug rehabilitation facility at 101 North El Camino Real.

While I support access to treatment and recovery services, I strongly believe this location is inappropriate and incompatible with the surrounding neighborhood.

This site is located approximately 850 feet from an elementary school and sits within a mixed residential and commercial corridor heavily used by families, children, seniors, and small businesses. Placing a high-intensity treatment facility in such close proximity to a school and established neighborhood raises serious concerns regarding:
• Public safety and neighborhood security
• Compatibility with existing residential uses
• Impacts to nearby schools and families
• Increased traffic and parking congestion
• Lack of meaningful, transparent community engagement
Additionally, many residents were not properly notified prior to the recent “listening session,” and questions raised by attendees were not fully addressed. The process to date has left many in the community feeling excluded and unheard.

Treatment services are important. However, the County has an obligation to carefully evaluate appropriate siting, ensure transparent public process, and prioritize community safety and compatibility.

For these reasons, I respectfully request that the County:

1. Pause all advancement of this proposal at 101 N. El Camino Real.

2. Conduct a fully transparent public process with proper notice to all affected residents.

3. Evaluate alternative locations that are more appropriate and less disruptive to families and nearby schools.

I urge you to reconsider this location and ensure that any decisions made reflect both compassion for those seeking treatment and responsibility to the surrounding community.

Thank you for your consideration.
