RE: Expert Environmental Opinion Regarding the Validity of the CEQA Notice of Exemption (NOE) – HBCSD Maintenance & Operations Building Project (8750 Dorsett Drive) – CUP No. 23- 014; Planning Commission File No. 24-485; Design Review Board Application No. 24-005; and City Planning Record No. PA-2023-0067
Honorable Mayor and Members of the City Council,
Pacific Rim EcoSystemic Strategy Advisors, LLC (Pacific Rim Eco) has been retained by Robert Granger and the concerned residents of Breton Lane to perform an independent professional review of the Huntington Beach City School District’s (HBCSD) California Environmental Quality Act (CEQA) determination for the proposed 7,525-square-foot Maintenance & Operations (M&O) Building.

Accompanying this letter is our formal Expert Environmental Opinion & Analysis. Our investigation concludes that the District’s Notice of Exemption (NOE) is factually and procedurally invalid. We identified five compounding, disqualifying problems that necessitate a full environmental review:
• Procedural and Baseline Violations: The District relies on an unlawful baseline of unpermitted M&O operations and filed its NOE prematurely—prior to a project decision or permit submission— violating CEQA Guidelines Section 15062(a).
• Misapplication of Class 3 Exemption: This industrial facility, intended to house heavy machinery and hazardous substances, does not meet the "similar structure" criteria of Class 3 (small stores or offices).
• Extraordinary "Unusual Circumstances": The project’s 22.5-foot proximity to residences, adjacency to a public park, and location within a cluster of significant environmental sites—including

the Ascon Superfund Site, the Cannery Street Landfill, and the protected Huntington Beach Wetlands—create a "reasonable possibility" of significant effect. • Regulatory Vacuum: The District’s incorrect claim of zoning exemption under Government Code §53094 bypasses essential local vetting for noise, traffic, and hazardous materials. • Public Health Risks: Our analysis highlights scientifically evidenced risks to community physical and mental health, exacerbated by the site’s shallow seasonal water table and poorly drained soils, which facilitate contaminant migration.

Intent to Present
Please be advised that Pacific Rim Eco will be present at the City Council meeting on May 5, 2026, alongside our clients. We intend to provide expert testimony summarizing these findings for the administrative record with the bounds of whatever times is allocated for this purpose.

Upholding CEQA safeguards now is the responsible path to protecting the health of Huntington Beach residents.

Subject: File #: 26-279 Appeal of Planning Commission"s Action on Conditional Use Permit No. 23-014 (HBCSD Maintenance and Operations Building)
Date: Friday, May 1, 2026 4:19:59 PM
Attachments: Invalid Claim that M&O is for classroom educational use .pdf You don't often get email from [email protected]. Learn why this is important RE: The Invalid claim by district that this is to be used for educational purposes and is considered classroom use
The argument that the Maintenance and Operations (M&O) building will be used by students for classroom use is entirely invalid because it directly contradicts the District's own published project descriptions, architectural plans, hearing testimonies, and legal building strategies.

If the District attempts to make this argument, you can easily defeat it using their own record:

1. The District Explicitly Admitted It Will Not House Students. The District's own website, FAQs, and Development Guides explicitly state that "The M&O facility will not host students". Furthermore, during the Planning Commission hearing, the District’s architect, Brian Whitmore, testified on the record that "this particular project does not house students".

2. The Project is Evading the Field Act. The District has publicly admitted that the new M&O building will be built using "local building standards in lieu of Field Act compliance." The Field Act is the stringent California safety code that is legally required for any facility attended by students and teaching staff. Under California law, if a building is not subject to the Field Act, it is officially classified as a non-classroom facility. If the District were to suddenly argue the building is for classroom use, they would be legally forced to comply with the Field Act and submit to a full structural and fire/life safety review by the Division of the State Architect (DSA), a process they intentionally avoided.

3. The State Architect Confirmed It Is Not for School Purposes In an email dated August 22, 2024, the DSA Regional Manager, Ron LaPlante, confirmed in writing that the DSA will not oversee the project's structural safety specifically because "this site is not used for school purposes".

4. The Floor Plans Prove Industrial and Storage Use The official project narrative and architectural plans submitted to the City designate the 7,510 to 7,525-square-foot building strictly for industrial maintenance and storage. The space is explicitly partitioned for woodworking, metalworking, groundskeeping, light mechanic work, a centralized warehouse for maintenance materials, and office space for the 14 M&O staff members . There are no classrooms in the blueprints.

5. It Triggers Mandatory Local Zoning Compliance Because the building is legally and functionally a non-classroom facility, it is subject to the limitations of California Government Code §53094(b). This state code explicitly dictates that a school board cannot exempt itself from city zoning laws when the proposed use is for "nonclassroom facilities, including, but not limited to, warehouses, administrative buildings, and automotive storage and repair buildings".

In summary, the District cannot legally argue the building is for student use without invalidating their entire permitting strategy, triggering mandatory state safety oversight under the Field Act, and contradicting their own blueprints and public testimonies. photo Robert Granger

Subject: Agenda Item #14 - Appeal of Planning Commission Action Conditional Use Permit No. 23-014 (HBCSD Maintenance and Operations Building
Date: Sunday, May 3, 2026 3:39:04 PM
I am a long-time resident of Huntington Beach. I urge you not to support an appeal of the conditional use permit No. 23-014 allowing the Huntington Beach City School District to build a maintenance building on its property at Dorsett Drive. None of the objections to the project are based in fact. The HBCSD has complied with all requirements and already operates from this site but in an outdoor parking lot. Moving the activity indoors will reduce noise, and there will be no increase in traffic, since the activity is already occurring at that location.

Alternative locations have been explored, the project has completed its CEQA review and been approved at every level in the City, meeting all city requirements, including zoning. Sound insulation and a block wall will separate the structure from neighboring properties.

Again, I urge you to allow this project to go forward.

Hello,
It feels very frustrating to have to write this email asking our city council to please move forward with the previously approved Maintenance and Operations Building that would so greatly benefit our community. It is especially frustrating that this is being fought and delayed by someone currently running a campaign on "putting Huntington Beach residents, small businesses, and community values ahead of outside interests." HB residents deserve wellmaintained schools and the safety and wellbeing of our children is certainly integral to our community values. I have children at HBCSD schools and who play soccer with AYSO on the fields that need this building desperately. I know that this project has already undergone multiple City review steps and has already been found to meet all the applicable zoning, building, and City requirements, so PLEASE, for our kids, let it proceed already!
Thanks,

Subject: Supplemental Communication re: Agenda Item 25: Fluoridation Date: Sunday, May 3, 2026 8:51:17 PM
To the Huntington Beach City Council:

I am trying to understand the Council’s new skepticism toward fluoridation. Not because skepticism is bad. Good science depends on skepticism. But science also depends on evidence, measurement, risk comparison and honesty about tradeoffs.

That is what seems to be missing from Council thought.

Science and technology are not abstractions. They are the basis of our prosperity, our health and our safety. They give us clean drinking water, antibiotics, vaccines, streaming sports, weather forecasts, earthquake engineering, cancer treatment, ED drugs, airplanes, smart phones. And dental care.

Take dental X-rays.

Every Council member has almost certainly had dental X-rays. So have your spouses, your parents and your children. Why? Because dentists use them to find cavities, infection, bone loss, impacted teeth and other problems that cannot always be seen with the naked eye.

But X-rays are not magic. They are electromagnetic radiation, the same broad family as visible light and ultraviolet radiation. In a beach city, we understand UV radiation very well. Around here, “SPF” is as common in our beach patois as “dude.” We teach our children to use sunscreen because UV light carries enough energy to damage skin.

And yet X-rays are far more energetic than UV. UV wavelengths are measured in hundreds of nanometers. Dental X-ray wavelengths are often fractions of a nanometer.

That means X-ray photons can carry thousands of times more energy than the UV photons we so passionately block with sunscreen. SPF.

So why do we accept dental X-rays?
Because the benefit-versus-risk question has been studied carefully. Because radiation dose is measured and governmentally regulated. Because dentists do not use X-rays randomly. Because standards exist. Because science has done the hard work of separating fear from evidence.

Guess what? That is also how fluoridation has been evaluated.

Community water fluoridation is supported by the American Dental Association, the nation’s largest dental association, representing about 152,000 dentist members. The ADA states that community water fluoridation at recommended levels is safe, effective and reduces tooth decay. The CDC says fluoridation reduces cavities by about 25% in children and adults. The recommended level is 0.7 milligrams per liter, a level chosen specifically to preserve benefit while limiting risk.

That does not mean there are no questions. High fluoride exposure deserves scrutiny.

Public-health policy should always be reviewed as new evidence develops.

But that is not what this Council appears to be doing.

This Council has already worked to ban masks against contagion. It has worked to ban or lock down library books. Now it wants to block fluoridation to recommended levels, a mainstream public-health measure grounded in decades of science.

So here is the obvious question:

Given the proven penetrating energy of X-rays, is the Council also preparing to ban dental X-rays in Huntington Beach?
If not, why not?
If your answer is that dental X-rays are useful, regulated, measured and supported by scientific evidence, then you have already accepted the principle. Public health does not ask whether something sounds scary in isolation. It asks whether the measured benefit outweighs the measured risk. A business principle and a life principle.

That is the standard for X-rays.

That is the standard for sunscreen.

That is the standard for electric power.

And that should be the standard for fluoridation.

Huntington Beach should not govern by suspicion of science. We are supposedly a modern city. Our health, safety and prosperity depend on scientific literacy, not political theater dressed up as concern.

The Council should follow the evidence, not fear of the word “fluoride.” Or a handful of vocalists.

To: CITY COUNCIL (INCL. CMO STAFF); [email protected] Subject: Support for HBCSD M&O Building
Date: Sunday, May 3, 2026 10:14:06 PM
You don't often get email from [email protected]. Learn why this is important Dear Honorable Mayor Casey McKeon and City Council
Members,
As a long-time advocate and volunteer for our
Huntington Beach City School District and a
taxpayer committed to fiscal accountability, I am
writing to urge the Council to deny the appeal and
uphold the approval of the proposed Maintenance
and Operations (M&O) building.

This project is a common-sense solution to a longstanding need. After years of operating behind the district office and paying nearly $1 million per year in lease costs—a staggering waste of taxpayer funds—the
District has presented a plan that is fiscally responsible and legally sound. There is no increase in traffic or
sound considering they’ve been there already for years.

The District has already committed $1.2 million to OVSD to house our busses and for future maintenance and
operations expenses. This was to alleviate the stress of the Sowers neighborhoods that didn’t want the busses
on the Sowers site. The district is always committed to working with the community and stakeholders. Thank
you OVSD!
In regards to the M&O building, moving it forward 10 feet as the appellant has requested not only negates the
CEQA but creates an unsafe environment behind the
building where undesirables can take refuge and do
drugs. Daily, the maintenance workers clean up needles
and trash behind the appellants house on the
pathway/easement to the softballs fields. The district
maintains the area as good stewards to the community.

As a local Realtor, I can say this will not drop property values or negate the appellants home owners insurance,
like he’s previously stated. He claims the heavy
equipment will negate his insurance. There is no heavy
equipment, large projects are conducted on school sites.

He also backs to the softballs fields where they run
heavy equipment twice a week.

The district site is quiet, unlike the many neighborhood school sites we have that have daily student drop offs
and pick ups, sports and events. This is what creates the culture and community of our HB neighborhoods. The
hustle and bustle; the sounds of our children playing on the playgrounds isn’t a negative thing, it was part of the original design of Huntington Beach. All our
neighborhood school sites actually increase homeowner
values.

The High Cost of Denial If the City denies this
project, it doesn't stop the building; it simply makes it more expensive for the public. The District would likely be forced to move the project through the Division of the State Architect (DSA). This shift would:

Inflate Costs: Force the District to abandon costsaving prefabricated plans for custom builds, costing taxpayers hundreds of thousands of dollars in extra
fees and additional time.

Bypass Local Input: Shift jurisdiction away from the
City to the State, removing local oversight.

Legal and Procedural Consistency: The City has no
valid legal cause to deny this project. It is not an
"industrial" use in a residential zone; it is a support facility for a school district that has operated on this site for years. Most school districts do not require a CUP for such sites because they are permitted uses.

To deny this project now, the Council would have to
declare that the Zoning Administrator and a 6-1
majority of the Planning Commission were "wrong"
in their interpretation of City Law. Such a reversal,
despite the project meeting every objective City standard and passing CEQA review, would be the definition of an
arbitrary and capricious decision, potentially exposing the City to unnecessary legal risk. Do all our school
districts in the city of Huntington Beach have CUPs for their M&O sites? I doubt that is a rabbit hole we want to go down?
A Commitment to Our Staff and Students: Our
HBCSD M&O staff has waited years for a safe, indoor
place to house their tools and equipment. They deserve
that! Moving their existing operations indoors reduces
noise and improves neighborhood aesthetics.

Every dollar saved on leases and construction
premiums is a dollar that stays in the classroom for
our 4,500+ students. I urge you to stand with our
students, our workers, and our taxpayers. Please
deny this appeal and do what’s right for our children!
I believe you will do the right thing.

Most Sincerely,
Laura Costelloe

To City Council:

Regarding Agenda item 14/ 26-279.

I am writing to encourage you to uphold the Planning Commission’s (6-1)approval of the HBCSD Maintenance and Operations building. I question the reasoning behind this agenda item that has provided a solution to a long-time problem and has the support of the VAST majority of citizens (except one citizen). How is that fiscally responsible? Why would we continue to pay nearly $1 million per year in lease costs? Why is one man stopping this for one citizen in a deal that has taken years to construct and approve?
There will be no impact in traffic or noise because they are already there operating.

The Zoning Administrator and a 6-1 majority of the Planning Commission supports this. Why is one council member giving one citizen this kind of attention and power? It doesn’t add up.

Deny the appeal - and support the approval of the Maintenance and Operations (M&O) building.

This would cause thousands of our school kids to lose because of this wasteful appeal. Support our students, our workers and let’s use our tax dollars wisely and use basic common sense.

Sorensen; Heather Sorensen; [email protected]; Susan Schaben Subject: Zoning Administrator Abuse: File #: 26-279 Appeal of Planning Commission"s Action on Conditional Use Permit No. 23-014 (HBCSD Maintenance and Operations Building)
Date: Monday, May 4, 2026 8:34:51 AM
We agree with you Pat,
“The Zoning Administrator, one person, has the Authority to approve CUP’s and Variances. This is not very common in other cities,” Burns wrote in a memo to his colleagues. “
The planning department should have invalidated the HBCSD CEQA Notice of Exemption from the get-go. By looking the other way at an obvious CEQA violation, it cleared the way for a review process of one. One person, the zoning administrator. Who knew the zoning administrator could look the other way when it comes to an industrial maintenance yard in a residential neighborhood? Let alone the district's CEQA consultants' professional credibility in her false and misleading testimony.

The city council needs to reject the CEQA NOE and start over with an open process that is subject to community involvement and complies with applicable CEQA guidelines.

Secondly, why is the city believing the districts' "experts" that it's too late to invalidate their CEQA Notice of Exemption?
Even though the Huntington Beach City School District (HBCSD) filed their Notice of Exemption (NOE) on November 1, 2023, attempting to run out the 35- day clock, their process was fundamentally flawed both procedurally and factually.

Here is why it is not too late to challenge their CEQA exemption:

1. Procedural Invalidity: The NOE Was Filed Prematurely Under CEQA Guidelines Section 15062(a), a public agency may only file an NOE after it has made a formal decision to carry out or approve a project. Furthermore, CEQA Guideline 15004(c) dictates that the CEQA process must be completed before the agency makes a decision.
• The Flaw: The District filed and recorded the NOE in November 2023, but did not formally resubmit its Conditional Use Permit (CUP) application to the City until April 10, 2024.
• The Legal Argument: By filing the NOE months before formalizing the project decision and submitting permit requests, the District triggered the 35-day window unlawfully. You can argue that an agency cannot "piecemeal" the environmental review by filing an exemption before a defined project action is actually submitted to the City for approval. Because the filing was procedurally invalid, the 35-day statute limit does not legally apply.

2. Inaccurate Project Description Restores the 180-Day Window The 35-day statute of limitations only provides immunity if the NOE honestly and accurately describes the project.

The Precedent: In the 2023 case Committee to Relocate Marilyn v. City of Palm Springs, the Court of Appeal ruled that if an NOE inaccurately describes a project, it deprives the public of a fair chance to evaluate it. The court determined that in such instances, the 35- day limit is invalidated and the standard 180-day statute of limitations is reinstated. • The Legal Argument: The District's NOE claimed the project involved "negligible or no expansion of existing or former use". However, the District established this "existing" baseline on operations that have been unpermitted and illegal since 2018 or 2019. By failing to disclose that the "existing use" was an unpermitted industrial yard, the NOE's project description was factually inaccurate and misleading, legally opening the door to reinstate the 180-day timeline.

3. "Equitable Tolling" Due to a Misleading Baseline Statutes of limitations are designed to protect honest administrative mistakes, not deliberate misrepresentations. • The Legal Argument: Because the District deliberately withheld the fact that its baseline was an unpermitted operation lacking a City CUP, this could be considered a "fraud on the record". When a lead agency achieves a CEQA exemption by misrepresenting the legality of its baseline, the statute of limitations may be subject to "equitable tolling". This means the "clock" can be paused or reset because the public was fundamentally misled by the original notice.

4. Zoning Violations Are Independent of CEQA Deadlines Finally, even if a judge were to uphold the expired CEQA deadline, the statute of limitations on CEQA does not grant the District immunity from ongoing zoning violations. CEQA (environmental review) and zoning (land use permits) are separate regulatory mechanisms. Under California Government Code §53094, the District is in continuous violation of the law by operating a non-classroom industrial facility in a residential zone without a City CUP. This ongoing zoning violation is not subject to a 35-day CEQA window.

From: Robert Granger
To: [email protected]; CITY COUNCIL (INCL. CMO STAFF) Subject: M&O building and operations conflict with Land Use Element Goals Date: Monday, May 4, 2026 2:46:31 PM
The proposed Maintenance & Operations (M&O) yard violates several key goals and policies outlined in the City of Huntington Beach General Plan (Adopted October 2, 2017), Land Use Element.

Here is how the project conflicts with the specific guidelines:

1. Incompatible Architecture and "Surf City" Identity (Goal LU-2 & Policy LU-2B) The Guideline: Goal LU-2 and Policy LU-2(B) require that new development preserves and enhances a "distinct Surf City identity" and that building architecture must be "contextsensitive, creative, complementary of the city’s beach culture, and compatible with surrounding development and public spaces."
The Conflict: During the Planning Commission hearing, now council member Don Kennedy pointed out the absurdity of the City claiming the project meets this standard, stating that "nothing speaks Surf City identity more than a prefab manufactured steel metal building in a coastal zone... it's ridiculous."

2. Disproportionate Scale and Elevation (Policy LU-1D & Goal LU-2B) The Guideline: Policy LU-1(D) dictates that new projects must be of "compatible proportion, scale, and character to complement adjoining uses."
The Conflict: Residents argue the building's scale is highly incompatible with the adjacent homes on Breton Lane. Because those residential properties sit at an elevation approximately 7 to 10 feet lower than the proposed building pad, the 17.5-foot-tall M&O building will actually tower 25 to 30 feet higher than the ground level of the neighboring homes

3. Encroachment of Incompatible Land Uses (Policy LU-2D) The Guideline: Policy LU-2(D) strictly directs the City to "maintain and protect residential neighborhoods by avoiding encroachment of incompatible land uses." The Conflict: Opponents argue that placing an industrial maintenance yard—which inherently involves early morning noise, heavy machinery, diesel trucks, and hazardous materials—just

22.5 feet from single-family residential property lines is a textbook example of an incompatible land use encroaching on a quiet neighborhood

4. Inconsistency with Community Park Integration (Goal LU-1) The Guideline: Goal LU-1 requires that new development be coordinated to ensure the land use pattern is "consistent with the overall goals and needs of the community." The Conflict: Neighbors note in their formal opposition letters that the project is inconsistent with the neighboring city park development plan. Rather than fostering community connectivity, the District's plan to build a continuous block wall along the western perimeter will wall off the city-owned corridor and walkway that connects the neighborhood to Edison Park, failing to integrate pedestrian and micro-mobility access Furthermore, residents argue that this very tight 10-foot-wide hidden corridor will create an attractive nuisance for criminal activity out of the view of police. And last of all, the higher fire risk associated with the building, chemicals, and fuels being stored so close to neighboring single-family homes. Are the insurance policy cancellations coming for these residents? Robert Granger

RE: Municipal Liability and Homeowner Insurance Cancellation Risks Stemming from CUP No. 23-014 (HBCSD M&O Building)
Dear Mr. Vigliotta,
Thank you for confirming that the items brought to your attention about CEQA will be vetted during the public hearing process during the appeal of this matter.

One more thing to advise the city council.

I am writing to formally alert your office to a severe and unmitigated financial risk facing the residents of the Kettler community should the City Council uphold the Planning Commission’s approval of Conditional Use Permit No. 23-014 for the Huntington Beach City School District (HBCSD) Maintenance & Operations (M&O) Building.

Beyond the existing California Environmental Quality Act (CEQA) and zoning violations previously brought to the City's attention, placing an industrial maintenance yard a mere 22.5 feet from single-family residential property lines exposes these homeowners to an immediate threat of severe property insurance rate hikes and policy cancellations due to modern, algorithm-driven insurance underwriting practices. The home insurance industry is currently undergoing a "Geospatial Revolution," shifting away from static annual contracts to a model of "Continuous Underwriting" driven by orbital data and scalable computer vision AI. Because of this, premium pricing and risk exposure adjust dynamically in real-time, responding instantly to environmental changes and property modifications detected from orbit. In this new landscape, "to be insurable is to be visible," and an AI algorithm is constantly scoring properties from the sky.

If the City allows the HBCSD to construct a 7,525-square-foot industrial facility—which will house diesel trucks, heavy machinery, wood and metal shops, and hazardous materials—just 22.5 feet from residential backyards, the City will be directly responsible for introducing a massive, algorithmic "Exposure" risk to the adjacent homes.

Modern insurance AI constantly evaluates a property's "Hazard Proximity" by quantifying external threats, such as encroaching fire risks or hazards near the parcel boundary. When the orbital telemetry scans Breton Lane and identifies a newly constructed industrial structure housing combustible materials and industrial operations abutting the residential fence line, the AI will automatically flag the residential properties as high-risk.

Consequently, the residents of Huntington Beach will be subjected to the "Consumer Shock" currently disrupting the insurance market: surprise non-renewal notices or massive premium hikes based on aerial imagery.

By illegally bypassing a formal CEQA Initial Study under a flawed "Small Structures" exemption and failing to evaluate the true environmental and hazard impacts of this project, the City is allowing a dangerous condition to be built that will directly trigger insurance cancellations for its citizens. We urge you to advise the City Council of the significant municipal liability the City assumes by forcing this unvetted industrial proximity onto residents. The City must overturn the approval of CUP No. 23-014 and mandate a full Environmental Impact Report (EIR) to properly evaluate the external hazards and resulting financial damages (diminution of value and loss of insurability) this project will inflict on the neighborhood.

I have a very short PowerPoint presentation on this new era of microinsurance underwriting. As an insurance professional for the last 33 years, I've seen a thing or two. Insurance companies are using AI to eliminate as many California risks as fast as they can. I receive frantic calls several times per week, "I've been canceled, and I don't know why".

Please advise the council that this increase in financial exposure/risk is being placed on our neighborhood. This is not an unpredictable natural disaster; it's just a disaster waiting to happen.

RE: Request for Legal Clarification on CEQA Responsible Agency Duties – HBCSD Maintenance & Operations Building (CUP No. 23-014)
Set for City Council Hearing on May 5, 2026
Dear Mr. Vigliotta,
We need your help! On behalf of the neighbors surrounding the Kettler Education Center to request your formal legal advice and clarification regarding the position taken by the Huntington Beach Planning Department on Conditional Use Permit (CUP) No. 23-014. Specifically, we are seeking an explanation of the City’s legal obligations as a "Responsible Agency" under the California Environmental Quality Act (CEQA) and why the Planning Department accepted the Huntington Beach City School District’s (HBCSD) Notice of Exemption (NOE) as valid without conducting its own separate, independent CEQA determination.

Please read the environmental report prepared by Dr. Daneil Barbara that is attached to this email.

Background: The HBCSD is seeking a CUP to construct a 7,525-square-foot industrial Maintenance and Operations (M&O) Building 22.5 feet from residential property lines at the Kettler site. Acting as the Lead Agency, the District filed a CEQA NOE on November 1, 2023, claiming a Class 3 (Small Structures) Categorical Exemption.The District’s exemption rests on the premise that the project merely moves "existing" operations indoors. However, the District relocated its M&O operations to this site around 2018 or 2019 and has operated this maintenance yard ever since without the required City Conditional Use Permit.

Questionable Procedural Tactics and Evasion of Public Scrutiny The District appears to have employed a highly questionable procedural tactic to intentionally evade public scrutiny and legal challenges by manipulating the CEQA statute of limitations. Specifically, the District officially recorded its Notice of Exemption (NOE) with the County of Orange on November 1, 2023. By filing this NOE, the District triggered a very brief 35-day statute of limitations for anyone seeking to file a legal challenge to its environmental determination. The District then deliberately let this 35-day window quietly expire before advancing the project with the City. The Conditional Use Permit (CUP) application and plans were not resubmitted to the City of Huntington Beach Planning Department until April 10, 2024, and the application was not deemed complete by the City until May 7, 2024. Furthermore, the District did not hold a Community Input Meeting to actually notify the public and neighboring residents about the project's design and impacts until May 6, 2024—more than six months after the NOE was recorded.

This calculated timeline demonstrates that the District intentionally let the legal window to challenge the NOE expire long before they formally notified the affected neighbors that the project was moving forward.

The City’s Duty as a Responsible Agency:

Because the City of Huntington Beach holds discretionary authority over the approval of the Conditional Use Permit, the City acts as a "Responsible Agency" under CEQA. Under CEQA guidelines, a Responsible Agency is required to comply with CEQA and "must independently review and approve the CEQA document, and not rely automatically on the Lead Agency’s judgments". The guidelines further state that a Responsible Agency complies with CEQA "by considering the EIR or negative declaration prepared by the Lead Agency and by reaching its own conclusions on whether and how to approve the project involved".

Furthermore, during the July 23, 2024, Planning Commission hearing regarding the appeal of this project, a City official explicitly stated on the record that the Commission "has to make its own CEQA determination... before it acts on the project".

Here is the pertinent part from the planning commission video of that meeting.

Here is the link to the exact point of this testimony
"Madalyn Welch: That's correct. The school district served as the lead agency.

Madalyn Welch: The agency prepared the notice of exemption document.

Ian Adam: And with what's the city's role to review that? If it does, the city review it to confirm those findings or at least weigh in, or would if they had a disagreement with that process?
HB Employee: Yes. The Commission has to make its own CEQA determination before it approves, but before it acts on the project."
Questions for the City Attorney:

Given this clear legal framework, we respectfully request your legal opinion on the following questions:

1. Why did the Planning Department accept the District's NOE at face value? If a Responsible Agency must not "rely automatically on the Lead Agency's judgments", why did the City Planning Department fail to question the District’s use of an unpermitted, illegal operation as a valid CEQA "baseline" to claim there is no expansion of use?

2. Did the City fail to conduct an independent CEQA evaluation? CEQA guidelines stipulate that if a Responsible Agency believes the Lead Agency's document is inadequate, it has the option to bring a legal challenge against the document, assume the role of Lead Agency, or waive its objections .

3. Did the City explicitly waive its objections to the NOE, or did the Planning Department simply fail to conduct the independent review required by law before the Zoning Administrator approved the CUP on June 19, 2024?

4. How does the City justify ignoring "Unusual Circumstances"? Under CEQA Guidelines Section 15300.2(c), a categorical exemption cannot be used if there is a reasonable possibility of a significant environmental effect due to "unusual circumstances". Placing an industrial maintenance yard that houses heavy machinery and hazardous materials just 22.5 feet from single-family homes is clearly an unusual circumstance .

5. Why did the City not conduct its own initial study to evaluate these unmitigated noise and hazard impacts before approving the CUP? The community relies on the City of Huntington Beach to protect our neighborhoods through proper zoning and environmental oversight. By accepting a flawed NOE for an unpermitted industrial facility, we believe the City has sidestepped its legal duties as a Responsible Agency under CEQA.

The city council needs your guidance on this issue. It is our position that the HBCSD is not exempt from an environmental review, wherever they decide to build this non-classroom facility.

We look forward to your timely legal clarification on this matter as we prepare for the final appeal before the City Council.

Subject: HBCSD M&O Building Project Vote
Dear City Council Members,
As a parent, a member of our community, and a voter who supported this Council, I am writing to you today regarding the upcoming City Council meeting on Tuesday, May 5, 2026, concerning the appeal of the Huntington Beach City School District’s Maintenance & Operations (M&O) Building project.

I am writing to respectfully urge the City Council to uphold the Planning Commission’s 6-1 approval of this project.

The District has spent over five years working with the City, OCTA, local realtors, and private landowners to find an alternative site, and this project has already completed CEQA review and has been approved at every level of City review. The district has proven itself to have done everything as it should to have this project approved.

This facility is essential for maintaining the schools that serve our 4,500+ students. Our M&O team is the backbone of our campus functionality, and they require a permanent, indoor home base to store tools and coordinate the work necessary to keep our schools safe and well-maintained. It is only fair that the council continues to uphold the vote to approve this building.

I understand there has been concern regarding this facility from a few (one) disgruntled community member(s), but the facts demonstrate that this project is a responsible and necessary solution for our district. The M&O team currently operates out of this site outdoors, and moving them into a 7,500 sq. ft. structure will actually reduce noise for the neighborhood. This building, which adheres to existing zoning, includes enhanced features like sound insulation, a block wall, and landscaping to ensure it fits the area appropriately.

Those that live near the area, willingly purchased a home that backed to a site that was owned by the district. Thousands of students and some of our most valuable district employees should not have to pay the price because they don’t like what their home has backed to since it was purchased.The facts demonstrate that this project is a responsible and necessary solution for our district.

Further delays in this approval process only serve to drain resources that should be going toward our students' education. I appreciate your time and your service to our community, and I ask that you please support this project by upholding the Planning Commission's vote.

Sincerely,
Lillian Altamirano

Subject: HBCSD proposed Maintenance and Operations Building Dear Huntington Beach City Council Members,
Our names are Pete and Linda Minko and we are residents that live at 21361 Breton Lane. We also vote every election. I am writing to express my strong opposition to the Huntington Beach City School District's (HBCSD) proposed Maintenance & Operations (M&O) Building. Adding a 7,500-square-foot, 17.5-foot-tall industrial building in the heart of our residential neighborhood is completely unacceptable.

South Huntington Beach has already suffered the cumulative health impacts of remediation at the Ascon site, the power plant,( STILL waiting for the old plant to be taken down, but we can now see the new one at the end of my street where we used to see sky) and the Cannery Street Landfill (currently Edison Park). We cannot add industrial solvents, heavy trucks, and noise pollution to this list of health and environmental scars.

We live in the neighborhood right by the park and we can't understand why the HBCSD should get special treatment. They need to find an industrial site and put this facility there, not in our neighborhood. My husband works on his cars in our tract but that doesn't give him the ability to open a repair garage on our property. We have worked hard to afford a home in this neighborhood. This will affect our property values and be an eyesore. It also allows for a blind spot on the path we take to the park which could add a dangerous element for our neighborhood.

Beyond the severe impact on our daily lives, I am deeply concerned that the District is attempting to push this project through using highly questionable and potentially illegal tactics. At the upcoming May 5th hearing, we urge the City Council to address these severe procedural overreaches:
● Illegal Baseline & Lack of Permits: The District is attempting to establish a "baseline" based on unpermitted, de facto industrial use that began around 2018/2019, despite lacking a City Conditional Use Permit (CUP). ● Misapplied Environmental Exemptions: The District is claiming a Class 3 "Small Structures" exemption. This is a massive overreach, as this exemption was never intended for an industrial yard containing heavy machinery and hazardous materials. ● Evasion of Oversight: The District claims an exemption from local zoning, but the Division of the State Architect (DSA) has confirmed that it lacks authority to issue conditional use permits or enforce local zoning. This leaves a non-classroom industrial facility completely unchecked in a regulatory gap. ● Safety & Park Conflicts: The proximity of this structure to residential property lines (only 22.5 feet) and its interference with the Edison Park walkway pose a significant public safety conflict and increase the likelihood of noise ordinance violations.

We cannot let the District bypass environmental and city oversight at the expense of our neighborhood's safety, peace, and property values. I urge the City Council to reject the District's Notice of Exemption (NOE) and demand that a formal Initial Study (IS) or Mitigated Negative Declaration (MND) be legally required before any further action is taken.

Pleas do not let this measure go through!

For the record.

The Cannery Street Landfill is also part of the Kettler Elementary School property. It has several wells to let off the methane gas, but there is no history of soil testing that was done similar to the testing done at the Edison Community Center Park for the city by Geosyntec Consultants. A copy of their report is attached but it does not include any boring tests on the Kettler Elementary side of the Cannery Street Landfill.

Subject: Focused Area Waste Limit/Depth Evaluation
Edison Park, Huntington Beach, California

INTRODUCTION
At the request of City of Huntington Beach, Community Services Department (City), Geosyntec Consultants Inc. (Geosyntec) has prepared this letter report documenting the results of limited subsurface investigations to evaluate the approximate lateral limit(s) and depth(s) of existing waste along a selected portion of the eastern edge of the former Canary Street Refuse Disposal Station (Landfill) at Edison Park (hereafter Site). The requested area for waste delineation at the Site is shown on Figure 1 as it was provided to Geosyntec by the City in January 2019. The objective of the scope of work performed by Geosyntec was to collect field data to support the City in its evaluation of potential locations/types of proposed facilities/amenities at the Site.

BACKGROUND
Edison Park was constructed over the Cannery Street Former Refuse Disposal Station, also previously known as Cannery Street Landfill (CSL) in early 1970s. The CSL is approximately 27.5 acres, located in the City of Huntington Beach at the northwest corner of the intersection of Magnolia Street and Hamilton Avenue. The site’s formal address is 21379 Magnolia Street, Huntington Beach, California 92647.

Some of the existing facilities/amenities at the Site are constructed on top of waste material deposited at the former CSL. Settlement, differential settlement, and potential sinkholes are typically expected to occur at facilities constructed on top of waste. The effect of settlement, differential settlement and/or a combination of both are observed at the existing tennis courts, sidewalks, open park areas and other hardscape/amenities at the Site. However, the surface expression of settlement/differential settlement is more pronounced in the vicinity of the Tennis courts potentially limiting the functionality and aesthetics of the Tennis courts.

HL1685B\Edison Park Waste Delineation Final Report
In 2018, the City retained Geosyntec to prepare a feasibility study to evaluate several alternatives for repairing or reconstructing settlement related damage to the existing park and recreational areas at the Site [Geosyntec, 2018].

Geosyntec performed two site investigations for this project – the first investigation was performed between in November 2020 in the landscaped areas within the requested focus area and the second investigation was conducted on March 2021 in the areas of the park within the focus area currently under concrete slab.

PRE-FIELD INVESTIGATION ACTIVITIES
Geosyntec prepared a Site-specific Task Hazard Analysis (THA) that identified Site conditions, potential hazards, hazard control, monitoring procedures, personal protective equipment, and emergency procedures. Prior to field investigations, Geosyntec notified Underground Service Alert (USA) of southern California to mark and clear utilities in, and near to, the investigation focus area to reduce the potential for accidentally encountering buried utility lines. In addition, Geosyntec utilized the services of GEOVision, Inc. to perform a limited geophysical survey of the investigation focus area (and other potential boring/test pit locations) to evaluate potential buried underground utilities/features prior to performing field investigations. Geosyntec also obtained permits to advance soil borings from the Orange County Health Care Agency, Environmental Health Division, required under Orange County Well Ordinance (County Ordinance No. 2607) [Permit No. 20-08-22 and Permit No. 21-03-07]. The DigAlert ticket confirmations, field sketches provided by GEOVision and the soil boring permits are included here in Appendix A.

Geosyntec had, under a previous authorization from the City, prepared and submitted to the South Coast Air Quality Management District (SCAQMD) the required permit application package in general compliance with Rule 1150 which included an Excavation Management Plan. The permit application, was submitted on April 30, 2019 and deemed complete on May 03, 2019 [Application Number: 612262]. The SCAQMD issued the permit on September 11, 2020. An SCAQMD permit was not required for the second investigation. The permit issued by the SCAQMD for the first investigation and a copy of the Excavation Management Plan is included here in Appendix B.

FIELD INVESTIGATION
Test Pits
Five (5) exploratory test pits were logged between November 24 and November 25, 2020 by a Geosyntec engineer under the direction of a Professional Engineer licensed in the State of California to evaluate the approximate lateral limit(s) of the existing waste in the approximate areas shown on Figure 2A. The logs were prepared based on visual field observations of the exploratory test pits’ exposed side-wall and retrieved soil cuttings.

The logs include a general description of the encountered soils in accordance with the Unified Soil Classification System (USCS) and Standard Practice for Description and Identification of Soils (ASTM D2488) as well as a field sketch of the exploratory test pit wall showing interfaces of encountered materials. Geosyntec subcontracted with American Integrated Services, Inc. (AIS) to excavate and backfill the exploratory test pits using a standard backhoe.

The proposed exploratory test pits commenced at the approximate waste limit estimated by TRC [2001] as shown on Figure 1. The exploratory test pits were advanced to an approximate depth of 5 feet vertically and horizontally until existing waste limits are visually observed. Once waste was encountered in the exploratory test pit, efforts were made to reduce the excavation of additional material. Waste materials were not, to the extent practical, removed from the excavation. The exploratory test pits were generally advanced until waste material was encountered or until an obstruction such as surface concrete or other infrastructure was reached. Plastic tarps were placed with plywood sheeting to temporarily stage the test pit spoils during the excavation. Additionally, approximately 10 ft by 20 ft fence panels with windscreen attached were used to serve as a work exclusion area and visual barrier on three sides. Existing grass and topsoil were segregated from the exploratory test pits and replaced after backfilling the test pits directly with the materials excavated from the test pits. Backfill material was compacted in place to help provide unyielding condition using a roller attached to the end of the backhoe, however, density or moisture testing was not performed and/or required. Test pit logs are provided here in Appendix C.

Test pits were first advanced vertically until the waste material was encountered, and then advanced horizontally in an eastward direction to determine the lateral limit of the waste.

The thickness of the soil overlying the waste were generally observed to range between 2 ft to 3.5 ft below the ground surface (bgs). Waste material was encountered at the five exploratory test pits (TP-1 through TP-5). Lateral limit of waste was delineated at test pits TP-1 and TP-2; however, the lateral limit of waste could not be identified at test pits Edison Park Waste Delineation

TP-3, TP-4, and TP-5. The approximate lateral limits of the waste as observed by the exploratory test pits are indicated in Figures 2A and 2B. A summary of test pit dimensions, thickness of the soil layer/depth to the top of waste is presented in Table 1.

Hollow-Stem Auger Borings
ABC Livion Drilling, Inc, working as a drilling subcontractor to Geosyntec advanced five (5) hollow-stem auger (HSA) borings on October 28, 2020 in the landscape areas and seven (7) HSA borings on March 12, 2021 in the concrete covered areas. The purpose of the HSA borings was to estimate the thickness of the existing waste layer at the approximate locations shown on Figures 2A and 2B. The HSA borings advanced near the estimated lateral limits of waste (i.e., HSA-1 through HSA-3) started approximately 5 to 10 feet to the west of waste limit as observed by the exploratory test pits. The purpose of these HSA borings (i.e., HSA-1 through HSA-3) was to evaluate the depth of waste at or near the lateral limits of waste as observed by field measurements from the exploratory test pits. The objective of the HSA borings advanced near the Tennis Court (i.e., HSA-4 and HSA-5) was to estimate the depth of existing waste in the vicinity of the Tennis Court area. The objective of HSA-2A through HSA-8A was to confirm if waste is present under the existing concrete slab and determine its depth, if present. Borehole logs for the HSA borings are provided in Appendix D.

Each boring was logged by Geosyntec field engineer and includes a description of the encountered soils performed in general accordance with the USCS and Standard Practice for Description and Identification of Soils (ASTM D2488). Soil samples were collected from the HSA borings for logging and visual identification purposes, but no samples were retained for laboratory testing. Split-spoon samples were performed generally on the soil Edison Park Waste Delineation

HL1685B\Edison Park Waste Delineation Final Report
material encountered at the bottom of the boreholes to estimate the depth of waste. Each boring was advanced to a minimum of 1 foot below the bottom of the waste material, or until refusal, to visually assess that bottom of waste was reached. The HSA borings were backfilled with hydrated bentonite chips and the upper six inches with topsoil. The cuttings were containerized in 55-gallon drums, stored on-Site pending waste profiling, and disposed off-Site by AIS under waste manifest. Groundwater levels encountered in the HSA borings were recorded using a water level indicator. The depths to encountered groundwater at each of the HSA are listed in Table 2.

The thickness of the soil overlying the waste material, as observed from the HSA borings were found to range between 2 ft to 3.5 ft bgs. Borings HSA-4 and HSA-5 were advanced to depths of 34 ft and 41.5 ft bgs, respectively. Borings HSA-1, HSA-2, and HSA-3 were advanced to depths of 11.5 ft, 16.5 ft, and 21.5 ft bgs, respectively. HSA-2A through HSA-8A were advanced to depths that ranged from about 16.5 to 18 feet. The depths of groundwater encountered in the landscape HSA borings (HSA-1 through HSA-5 performed) were observed to range between 8 and 12 ft bgs. The depths of groundwater encountered in borings (HSA-3A through HSA-5A, HSA-7A and HSA-8A) were observed to range between 12.5 and 16.5 ft bgs. Groundwater was not encountered at borings HSA-2A and HSA-6A. The depth of waste was identified in the HSA borings where waste was encountered except HSA-4, which hit refusal at a depth of 34 ft bgs before reaching the bottom of the waste. A summary of the HSA borings including the depth/thickness of the soil layer and waste, and the depth to groundwater is presented in Table 2.

The approximate locations of the exploratory test pits and HSA borings were recorded using a hand-held global positioning system (GPS) unit.

Daily field reports with photo logs for the field investigation activities are included in Appendix E.

Air Monitoring
Geosyntec provided air monitoring services during the first field investigation phase of the project. The air monitoring was performed by Geosyntec in general accordance with the requirements of the SCAQMD Rule 1150. The general prevailing wind direction at the site was typically onshore from the west-southwest to east-northeast. The upwind and downwind monitoring locations are shown on Figure 1.

In accordance with the requirements of the SCAQMD Rule 1150, the following air quality parameters were monitored:
• Particulate matter (dust) as PM10 – PM10 monitoring will be performed using a DustTRAK DRX Handheld Aerosol monitor. Dust monitoring was conducted approximately every 60 minutes throughout the workday at the upwind and downwind monitoring locations. Action levels for dust at the monitoring locations was set in accordance with the SCAQMD Rule 1150 requirements at 0.05 mg/m3 above background. The recorded PM10 levels were below the action level of

0.05 mg/m3
above background.
• Total Organic Compounds (TOCs) as methane – Continuous monitoring of TOC was conducted using an QRAE III monitoring equipment at the working face of Edison Park Waste Delineation

the excavation and at the downwind property monitoring location. The maximum sustained readings (greater than 15 seconds) were recorded at approximately every 15 minutes. Action levels for TOC readings at the excavation face and downwind property monitoring location was set at 500 ppmv and 200 ppmv, respectively, in accordance with the SCAQMD Rule 1150 requirements. The recorded TOC level were below the action levels at the monitoring locations. • Odor – Unusual odor or increase in odor was not detected by Geosyntec personnel during the test pit excavation or HSA drilling.
• Local Weather – Local weather parameters were monitored at approximately every 15 minutes throughout the workday. Ambient Temperature (℉), and Wind Direction were monitored digitally from the KCAHUNT143 weather station located in close proximity to the Site. Wind Speed (miles/hour) was measured using a handheld Kestrel 4000 monitoring device.

Daily air monitoring logs are provided in Appendix E.

FINDINGS
Waste Delineated
Lateral limits of waste was delineated at two test pit locations (TP-1 and TP-2). Figure 2 shows an approximate limit of waste as identified from the test pits. The approximate depths to the encountered waste layer at TP-1 and TP-2 were 3.5 ft bgs and 3 ft bgs, respectively.

Waste Not-Delineated
Waste was identified at three test pit locations (TP-3, TP-4, and TP-5); however, the lateral limit of waste was not identified. It is likely that the lateral limits of waste at these locations may extend eastward past the obstruction such as the concrete slab at TP-3 and TP-4, and concrete sidewalk at TP-5. The approximate depths to waste from existing surface at TP-3, TP-4, and TP-5 ranged between 2 to 3 ft bgs.

Waste Depth
The depths of waste at HSA borings near the estimated lateral limits of waste (HSA-1 through HSA-3) were found to range between 10.5 ft and 20.5 ft bgs. The depth of waste at HSA-5 near the northern edge of tennis court was observed to be approximately

40.5 ft bgs. The depth of waste at HSA-4 near the southern edge of the tennis court could not be identified due to refusal, however waste was still observed up to 34 ft bgs. The Edison Park Waste Delineation

HL1685B\Edison Park Waste Delineation Final Report
depths of waste at the borings under concrete slab (HSA-2A through HSA-8A) were found to range between 5 ft and 15 ft bgs.

Waste and Soil Layer Characteristics
The soil layer at the Site was visually classified as silty sand (SM) in general accordance with ASTM D2488. The thickness of the soil layer generally ranged between 2 to 3.5 ft bgs. The waste material encountered at the site generally composed of dark gray asphalt concrete debris and decayed wood pieces within the landscape areas and dark gray, medium to high plasticity clay soils, with trace debris and slight organic odor within the concrete slab areas. The waste materials did not have any unusual odor. The above characteristics of the waste material was consistent throughout the investigation locations.

Groundwater
Groundwater was encountered at all five HSA boring locations in the landscape areas and all but two HSA borings in the concrete slab areas. The depth to groundwater in the landscape borings generally ranged between 8 to 12 ft bgs. The depth to groundwater in the concrete slab borings generally ranged between 12.5 to 16.5 ft bgs except at HSA-2A and HSA-6A where groundwater was not encountered.

SUMMARY AND RECOMMENDATIONS
In general, existing waste limit was delineated along the Eastern limit of the CSL as identified by Test Pits (TP-1 and TP-2). However, the existing waste limit along the Southern Section of the Eastern limit of CSL was not delineated due the existing structures and/or concrete lined areas. Test Pits (TP-3, TP-4 and TP-5) were advanced until the test pit encountered a structure and/or lined areas. Based on borings HSA-2A through HSA-8A, traces of waste material impeded within soil layer is present under the concrete slab within the focus area as shown in Figure 2B. However, the exact waste amount that maybe impeded in the soil layer located in areas under the concrete slab of the site is not known. Geosyntec recommends that field observations and monitoring services are performed by an experienced landfill engineer during the construction and/or excavation phase of the project to help further identify the limit of potential waste materials. Geosyntec also recommends that excavation and/construction activities in the areas described in this letter report are performed by a licensed Contractor with extensive experience in working in landfill environments. Proposed design features, amenities and structures should take into consideration the potential presence of waste materials in the areas described in this letter report. Furthermore, Geosyntec recommends that the design team for proposed structures and park amenities work closely with an experience landfill Edison Park Waste Delineation

DFR-001 - GEOPHYSICAL UTILITY CLEARANCE - 9.23.2020 1 of 4 Time Field Work Activities
0700 Arrived on site and met with GEOVision field crew Martin Garcia and Christopher Collins. 0705 Held a brief tailgate safety meeting. GEOVision crew acknowledged the THA. 0710 Performed a site walk with GEOVision crew to observe the proposed investigation locations (HSA-1 through HSA-5; TP-1 through TP-5).
0730 GEOVision started utility clearance survey at location of TP-1 test pit. Some utilities (likely irrigation and main water line) were encountered within 5 ft of TP-1. GEOVision marked a new location 14 ft north of the existing TP-1 location. 0800 GEOVision performed utility clearance survey at location of HSA-1 boring. No conflicts were found at HSA-1 location. 0810 GEOVision performed utility clearance survey at location of TP-2. Electrical and irrigation utility lines were located within 3 ft of TP-2 location. GEOVision marked a new TP-2 location 10 ft south of the existing location. 0820 GEOVision performed utility clearance survey at location of HSA-5 boring. No conflicts were found at HSA-5 location. 0835 GEOVision performed utility clearance survey at locations of TP-3 and HSA-2.
