The Parallel Tracks: How Horizon Towers' Leak History and Its Concrete History Never Met Until 2023

Drafted: 2026-05-09 Source: Synthesis of tbeam-citation-backbone.md (61 sourced claims), covid-forward-audit-log.md (11-file Drive minutes audit), the four era audits (era1-era4), fca-summary.md, and minutes-audit-progress.md. Documentary tone per Brad's directive — dates and verbatim quotes carry the argument; the reader draws their own conclusions.

The thesis in one paragraph

For roughly thirty years, Horizon Towers' boards documented two distinct maintenance tracks in their meeting minutes — and the documents do not show them ever being considered together. On one track, water was appearing in places it shouldn't: drips in garage levels, ceiling stains, balcony seepage, basement intrusion. The recorded responses were caulk, tar, paint, sealant, paint over the stain. On the other track, the building's own concrete was visibly deteriorating — cracks in beams, exposed reinforcement at hangers, prior bracket repairs that themselves cracked. The recorded responses were patches on the beams themselves, often by the maintenance person, sometimes with materials the board chose to save money. Both tracks ran for decades. The 2023 Knott Lab Facility Condition Assessment was the first document in the audit corpus to describe them as one connected problem — moisture intrusion driving structural concrete damage. By then the cost had compounded.

The two tracks defined

The leak track. Water findings recorded in board minutes: roof drips, unit ceilings, garage staining, balcony seepage, drains backing up. The recorded response is consistently surface-level — caulk, sealant, tar repair, paint over the stain, replace the failed sealant with another sealant. The pattern starts at least as early as the 1994-95 era ("we tried to fix the leaks in the garage by caulking the entry area") and continues through November 2024, when the board itself recorded that a fire-notifier panel failed because of "a previous tar repair that failed."

The T-beam track. Concrete findings recorded in board minutes, when they are recorded at all: visible cracks in garage ceilings and beams, "spalling" (concrete flaking off in chunks), exposed steel reinforcement, prior bracket repairs that themselves developed cracks. The recorded response is consistently in-house: the maintenance person patches the visible damage with concrete repair products selected for cost. The 2023 Knott Lab FCA described "modified corbel bracket repairs that have themselves cracked," indicating prior owner- side patching of structural members. The minutes located in the audit do not record an outside engineering review of any concrete element prior to the 2023 FCA.

Why the two tracks didn't converge

The disconnection is itself documentary. In the minutes record:

• The 2009 era 2 audit recorded January 2009 minutes flagging "33 units have water heaters 10 years old or older. These are in danger of rupturing. Water damage" — the response was an inventory check, not an envelope review.
• The 2010 minutes record "$30,000 has been spent this year to prevent water leakage into P-1, P-2" — substantial spend on the leak track, but no recorded discussion of what the water might be doing to the concrete it was passing through.
• The August 15, 2022 board agenda lists "Water Leaks" as Old Business and "Drain Issues" as New Business — two separate agenda items rather than facets of one moisture-management problem.
• The April 2024 owner ballot — circulated AFTER the 2023 FCA — is the earliest board-issued document in the audit corpus that explicitly names "Double Tee Beams — Cracks and Corrosion - Grade D" alongside "Exterior Slab Moisture Intrusion." That language came from Knott, not from the board's own diagnostic process.

Without an engineering eye to draw the line from one track to the other, the boards over multiple decades treated each set of findings on its own terms.

Decade-by-decade evidence

1992-94: The in-house policy is articulated from the start

The 1992-94 annual meeting PDFs added to the audit corpus on May 9, 2026 (foundational documents that predate the era 1 audit by 4 years) establish that the in-house DIY maintenance pattern wasn't a drift — it was articulated policy from the building's earliest documented years.

The 1993 annual meeting financial report shows total expenses of roughly $190,000 with a specific line item: "Professional Fees: .00" — zero dollars spent on professional consultations that year, against $48,500 manager salary and $6,962.95 maintenance labor.

The 1994 annual meeting captures the same policy in words:

"we contain inflationary costs by accomplishing many of our repairs and maintenance 'in house' rather than with outside contract labor, and by a myriad of other efforts attributable primarily to Buzz and Donna's expertise."

This is the in-house track stated as policy in 1994. The era 1 and era 2 audits document its consequences: caulk on leaks in 1994-95, patches on garage drainage in 1996, repeated reactive moisture work through the 2000s. The policy succeeded at containing line-item costs. What it didn't have, in either of the foundational years or the decades that followed, was an engineering perspective that could connect findings across the two tracks.

1996-2003: Awareness without integration

The earliest minutes located in the era 1 audit document leaks at the building. By 1996 the board was already responding to specific leaks (Units 803 and 101) and a P-1 garage water-intrusion finding. A 1996 minutes reference establishes the pattern: "We tried to fix the leaks in the garage by caulking the entry area."¹ The remediation method named is caulking; the diagnostic method is not named.

The board documented a systemic recognition: "We've discovered many deficiencies typified by the LEAKING IN THE GARAGE LEVELS."² Reserves were increased 10% specifically for aging-building work.³ The 1998 minutes record that an Odyssey Roofing contract for $8,803 covered only the east side of the roof, ten feet back.⁴ "Because the cost is $3,000 the board decided" garage cleaning would be deferred.⁵ A 1999 8th-floor roof leak triggered a $1,600 insurance claim.⁶ Across these 1994-1999 entries the patching pattern repeats: a leak is found, caulking or sealant is applied, the cleaning is deferred, the roof contract is sized to a fraction of the roof, an insurance deductible is paid for water that reached an interior ceiling. The minutes located do not record a comprehensive remediation in this period.

A 1996 work-order presentation by board member Patsy Endner documented the original construction's drainage gap directly: "Water in garage areas. A 3" drain pipe has been found on P-1. This was a part of the system that was never finished. The pipe to complete this drain will cost $750.00. A professional will repair the corner of the membrane and a slope toward the drain will be established. A core drill will be rented and 4 holes will be drilled. Total cost should be $874.00, plus the roofer."¹⁸ The phrase "the system that was never finished" refers to the 1984 original construction. The board documented an unfinished construction-era drainage component twelve years after the building opened.

The era 1 audit notes that Mike Krueger was contracted in 2003 to "remove and replace the garage roof" — the first comprehensive envelope action, roughly 9 years after the 1994-95 caulk attempt.⁷ The 2003 minutes do not record an engineering inspection of the concrete elements above which the roof would sit. The contractor selected was a roofer; what he installed was a roof.

T-beam track during this period: the era 1 audit did not surface explicit "T-beam" or "double-tee" terminology. Concrete-specific findings recorded include "exterior wall structural holes" (2002), addressed reactively rather than as part of any engineering review.

2004-2011: The patches intensify

The era 2 audit located 284 individual moisture-or-leak findings across this period. Patches accumulated; professional consultations occurred but were event-driven, not strategic.

A representative entry from June 30, 2005: "Michelle Smith will charge $500 to just reseal the red concrete. Perry said he could buy sealer for $50/$100 and he and Jack could do it."⁸ The minutes show the cheaper in-house option being chosen. The era audits record similar choices throughout this stretch.

In June 2007, the same roofer who had handled the 2003 garage roof contract reported during a leak repair that "dry rot exists in most of the corners and parapets" and recommended action before further damage. The recommendation was from a roofing contractor, not an engineering firm.¹¹

In August 2009, the board explored engaging an engineer for the P-3 garage planter leaks. One engineer's quote was $1,100 to come out plus $2,400 for solution help plus $70 per hour, with the note that those fees did not include any actual work. The board did not engage that engineer. A college-engineer referral toward a water-specialist engineer was discussed; no subsequent contract with a water specialist appears in the extracts read.¹⁷

In August 2010, with leaks accelerating, the board recorded that "$30,000 has been spent this year to prevent water leakage into P-1, P-2, P-3, and under the foundation." The sealants installed were noted in the same period as "not installed correctly" — Rod (the in-house maintenance person) re-applying after the prior application failed. Water catch troughs were installed in P-3 as a workaround. The same Aug 11, 2010 entry recorded: "At this time there is not any significant structural damage identified."¹⁰

The 2011 EPDM roof replacement was the era's largest envelope project. The contractor was TL Roofing (also written T&L Roofing in some entries). The 2011 reserve-fund ledger records the main scope in two line items: "Replace - Main & 2nd Floor Roofs — $70,475.00 (Completed)" and "Replace/Insulate Roof Parapets — $17,612.00 (Completed)" — combined main scope $88,087. Adjacent reserve-fund lines for the same season pushed total 2011 reconstruction-related reserve outflow to $136,266.07 by year-end.¹⁹ During the work the board recorded a discovery: insulation in the parapet walls was missing — not a known condition before the project began. The May 2011 Annual Meeting President's report characterized the project as "completed and turned out to be a much bigger job than originally anticipated."

The 2023 Knott FCA later found, without ambiguity, that this 2011 replacement was installed over the original membrane (an incorrect detailing choice), with the EPDM placed in front of the stucco rather than behind it, and that the installed membrane had shrunk and pulled away from the parapet by 2023. The era 2 audit does not record an engineering review of the 2011 work as it was being designed or performed.

T-beam track during this period: in November 2012 the board recorded that "An engineering firm has been hired" for "Twin-T deterioration" — meaning structural concrete in balcony framing. A verbal report was received; the minutes record the board "aggressively seeking a written report." The era audits do not surface a follow-up written report in subsequent minutes, nor do they record connection of this finding to the leak track.⁹

2012-2014

The era 3 third-party audit, compiled from a partial set of minutes, characterized 2012-2014 as a "deceptive quiet." Direct extraction of the 2013 HTCA Board Minutes PDF in 2026 supplies items the era 3 source set did not include.

The 2013 President's year-end report contains the following items.

Twin T reinforcement. "Previously water damage and efforts to prevent water draining into the P-3 Garage had caused damage to concrete support beams on the P-3 and P-2 garage floor structure. These beams were reinforced with steel brackets." This is the first appearance in the 2001-2015 minutes corpus of the leak track to structural track causation stated in one sentence. "Twin T" is the building's term for the double-tee precast concrete beams that Knott Lab in 2023 evaluated. The 2013 board-minutes "Projects Active" recap pins the contract date for this work: "Twin T Support Repair, Contract let Jan 21, 2013, and work to begin April 2013." The contractor's name is not present in the 2013 minutes. The minutes do not record an engineering review of the bracket design or of the underlying concrete condition. No structural engineer or engineering firm is named in connection with this work.¹²

Soffit failure. The 2013 report acknowledges: "Last year I reported on the completion of the Building Soffit repair. This year I have to report we have experienced water damage on one soffit. It is our current intent to evaluate through this fall/winter weather cycle before we initiate any activity to repair the damage."

Garage drainage maintenance. The same report describes the 2012-2013 actions as raising the canopy poles, finding and filling holes, and applying concrete sealant. No engineering firm is named in connection with these actions.

The 2011 EPDM installation that the 2023 FCA later identified as installed incorrectly was failing silently during this period. Membrane shrinkage and detachment do not produce visible damage until the gap is large enough to admit water in volume. The 2013 soffit reappearance is consistent with this pattern.

2015-2021: Symptoms return; no FCA, no reserve study

Between 2015 and 2018 the era 4 audit found no reserve study and no FCA in the minutes. Maintenance was reactive, symptom by symptom.

2019-2021 brought the first documented post-2011 moisture event in P-1: condensation collecting in the garage sprinkler drain lines, causing a valve failure. The recorded remediation was heat tape — a patch.¹³

2021 actual repair spend reached $121,618 against a $76,000 budget, a 60% overrun.¹⁴ More than $50,000 was transferred from reserves during the year to cover operational shortfalls.¹⁵ Despite the overrun, the era 4 audit did not surface a comprehensive engineering study commission in the 2021 minutes.

Brad's testimony (May 8, 2026) adds context not present in the minutes themselves: "Since COVID HT went through board members like fodder. We are supposed to have 5; we never got through a term." The 2021 board (Elliott, Arguello, Reece, Murray) was new. Boards facing a deferred-maintenance backlog were also facing structural turnover that limited any one board's ability to commission long-horizon work.¹⁶

2022-2023: The boiler crisis and the unfindable leak

The 2022 file (2021 - 2022 Annual Meeting and mixed scans.pdf) records two unbudgeted events that drove reactive spending: the January 2022 boiler catastrophic failure ($63,834, half from reserves and half from a $384.54-per-unit special assessment) and the July 2022 unfindable sewer-stack leak in Unit #304. The Bray property manager's July 5, 2022 email captures the response pattern:

"Plumbers of Elite Plumbing, Raven Plumbing and Rooter Roter have also been on-site looking for the leak. ALL plumbers have indicated that there is probably a hairline crack in a pipe or a fitting that has failed somewhere in the vertical sewer stack which runs down the 04 units somewhere from the roof to the 1 floor. BUT NO ONE has been able to see the actual leak."

The proposed next step was to call another plumber. The records located do not show an engineering review proposed for an active leak running through the building's vertical infrastructure.

The boiler that failed in January 2022 had been flagged in 2006-2009 minutes as 16-20 years old. No replacement was scheduled. The era 2 audit notes the minutes recording its age, then nothing. The catastrophic failure was the next entry in the board record.

The August 15, 2022 board agenda treats "Water Leaks" (old business) and "Drain Issues" (new business) as separate agenda items.

In late 2022 the 2023 budget was prepared. The proposed budget documents added a "Maintenance person" line at $5,200/month ($62,400/year). Bray Property Management had been terminated in August 2022; HTCA self-managed from September 2022 onward. Charlie Garner was hired as Office Manager and Ryan Coven (also of Coven's Plumbing per the standing-vendor list) as in-house maintenance. The board chose plumbing capability. The records located do not show structural or engineering capability brought in.

October 25, 2023: The convergence

Knott Laboratory delivered the Facility Condition Assessment for project number 20849 on October 25, 2023. The report described both tracks as one connected problem:

"The American Concrete Institute states that all progressive concrete deterioration mechanisms involve water. In general, Knott observed deterioration of the pre-cast double tees has been largely caused by moisture intrusion. There is a significant degree of moisture intrusion along all joints surrounding the concrete double tees."

Four conditions were graded D ("Unsatisfactory: Repairs and Maintenance Required — structural condition is of genuine concern"), all moisture-related: Double Tee Beams, Exterior Slab Moisture Intrusion, Grading and Drainage, and the Lower EPDM Roof. The report also documented:

"Notably, the most severe web cracks all occur where the modified corbel brackets have been installed as a repair for the severe cracks that originally relied only on Cazaly hangers for end connections... Severe cracks were observed where these modified corbel brackets have been installed on parking garage levels P3 and P2."

That sentence is the audit's clearest record of the in-house T-beam track: someone had installed corbel-bracket repairs on the structural double-tees, and those repairs had themselves cracked. The 2013 board-minutes "Projects Active" recap pins the contract-let date for the Twin T support repair to January 21, 2013, with work beginning April 2013; the contractor name is not present in those minutes. The Knott FCA itself attributes installation of the modified corbel design to Pinnacle Construction "approximately 8 years ago" (October 2023 minus 8 years = approximately 2015), a less-specific date than the 2013 minutes record.

At the November 6, 2023 annual meeting, the treasurer's report referenced "the anticipated bill from Knott Engineering had not yet been received." That is the earliest dated board-meeting reference to Knott Engineering in the audit corpus, twelve days after the FCA delivery. The annual-meeting minutes for that day do not record a substantive briefing on the four Grade D findings. The 2023 P&L records the Knott engagement on the books at $23,980.84, booked unbudgeted ($0 budget vs. $23,980.84 actual).²⁰

2024-2026: The catch-up payment

At the March 11, 2024 board meeting (Brad attended as a director), President Spath reported:

"Due to the work not having been scheduled or a plan put in place the lenders have now put HT on a list which will stop any future loans until the work is completed."

A unit-sale process had triggered lender review of the Knott report. External market pressure was now applied to the deferred items. The records located do not show internal urgency before that lender event.

The April 2024 Reconstruction Assessment ballot — circulated to all 83 owners — proposed a $325,000 special assessment ($4.1805 per heated square foot) to fund Summit Sealants on the T-beam and exterior slab moisture work ($220,000), garage roof membrane replacement ($85,000), and Knott engineering oversight ($20,000). The ballot text named "Double Tee Beams — Cracks and Corrosion - Grade D" verbatim — the earliest board-issued document in the audit corpus to use that phrasing.

The ballot also recorded that of six Knott-recommended Colorado contractors, only Summit Sealants returned a proposal; the others were either booked through 2024 or declined.

Two owner ballot comments captured contemporaneous owner sentiment:

"This is a vote of No Confidence in the immediate past Revolving Board of Directors... I have little faith that the current laundry list of repairs will be completed On Time or On Budget." — Bill Carter, Unit 505

"I will vote yes on this assessment, and will make my payments in the 5 month increments offered. However my payments will be contingent on the progress the board makes on this massive project." — Linda Scheve

President Spath responded to both in writing. The assessment passed.

The May 13, 2024 board meeting approved the CRW Roofing contract (work to begin May 14) and authorized Spath to pursue the final Summit Sealants contract. The same meeting documented Treasurer Hatfield's removal mid-meeting after distributing an "unauthorized printed report and comments document of 8 pages" to the board and owners present. Hatfield refused to approve the minutes.

The November 20, 2024 minutes recorded the Summit Sealants project halt for winter (down-payment paid, work to restart in spring) and, separately, the failed-tar-repair fire-panel incident:

"The 2nd floor patio leak to the office was due to wind driven rain that Grand Junction had in June 2024 which caused damage to the fire-notifier panel. The source of the leak was a previous tar repair that failed."

Tar repair, on a high-rise concrete patio, decades after the industry had established that tar was not the appropriate material — failing in 2024 to the point that a fire-safety panel was water- damaged.

The January 27, 2025 minutes recorded a follow-up Knott report dated December 17, 2024, the board's plan to hire a project manager by February, and an anticipated March 2025 restart of the Summit work. By the February 16, 2026 board meeting, the board was back to soliciting fresh bids — $1.27M (Summit) to $3.69M (an elastomeric coating contractor) — for what the audit log identifies as the FCA's Grade C scope (façade joint sealants, balconies, exterior repaint), not the original Grade D work.

The Grade D work — including the T-beam concrete repairs Knott called out — entered an unclear status after the November 2024 winter halt. The 2025 minutes available on htca81506.net (Wix-hosted, sandbox- blocked from this audit corpus) would be needed to fill the gap.

The cost of the connection-never-made

Cost figures sourced from the corpus extraction May 9, 2026 (the May 9 corpus pass extracted dollar amounts that earlier era audits flagged as not yet found):

• 1996-2002 era of caulk, partial roof repairs, deferred cleanings: on the order of $20,000-$40,000 of reactive moisture work per the era 1 audit conclusion. The 1996 board minutes specifically record $71,637 in reserves with ~$12,600 going to "stucco, concrete, roof repairs."
• 2002-2003 first comprehensive garage roof replacement (Mike Krueger / Kruger Roofing, Inc): proposal accepted October 2002 for "approximately $20,000"; actual paid $20,111 per the May 29, 2003 Quarterly Meeting Financial Update.
• 2007 reserve drain event: $98,000 of projects mid-year drained reserves; special assessment (exact amount not itemized) followed, estimated $30,000-$40,000.
• 2009 elevator project contingency: $36,000 set aside, later returned to reserves.
• 2010 single-year moisture spend: $30,000 per the August 2010 minutes ("estimated $30,000 has been spent this year to prevent water leakage into P-1, P-2"). Plus a $60,280 special assessment collected in 2010 for "roof & water damage" (per the Reserve Assessments Chronology).
• 2011 roof / patios / soffits / water damage project: total spending >$124,000 per the Reserve Fund Timeline 1992-2018. This was the "comprehensive" reconstruction that included the EPDM replacement the 2023 Knott FCA later found had been installed incorrectly (over the original 2011 membrane). The dollar amount is the all-in figure; the EPDM-only line is not broken out in the minutes located. By year-end 2011 reserves had been depleted to ~$40,000.
• 2013 reserve crisis low: $11,906 in the reserve account in November 2013 — the lowest since 1992. The board's leak/T-beam remediation capacity at this point was effectively zero.
• 2017 pool boiler replacement: $44,000 total, of which $24,900 was a special assessment (member-vote approved). Reserves jumped back to ~$108,000 by early 2017.
• 2018 HOA fee increase: +$39/unit/month (~$29,952/year additional revenue).
• 2021 actual repair spend: $121,618 against a $76,000 budget per the era 4 audit; $50,130 transferred from reserves during the year to cover operational shortfalls.
• January 2022 boiler catastrophic failure: $63,834 reactive replacement; $31,917 from reserves + $31,917 owner special assessment ($384.54/unit).
• April 2024 Reconstruction Assessment: $325,000 special assessment ($220K Summit Sealants on T-beams + Exterior Slab, $85K membrane roof replacement, $20K Knott engineering oversight).
• February 2026 bid range for the next phase (Grade C scope — façade joint sealants + balconies + exterior repaint, NOT the Grade D items): $1.27M-$3.69M.

The trajectory makes the connection-never-made legible. The 2003 Kruger garage roof was $20,111 — what the building spent for its first comprehensive envelope action after roughly nine years of patches. The 2011 follow-up package, intended to address the deterioration that had compounded, ran more than $124,000 — six times the 2003 figure. By the time the 2023 Knott FCA finally specified the work the building actually needed, the price had risen to $325,000 for the funded portion alone, with another $1.27M-$3.69M of related work still being bid. Each comprehensive action arrived roughly a decade later than the diagnostic evidence in the minutes warranted, and each was followed by a cycle of patches that compounded the next round of damage.

The 2011 case is particularly instructive. The building spent

$124,000 on a "comprehensive" roof + patio + soffit + water- damage package; the 2023 Knott FCA found that the EPDM portion of that package had been installed over the original membrane (an incorrect detailing choice) with the EPDM in front of the stucco rather than behind it, and that the membrane had shrunk and pulled away from the parapet by 2023. Twelve years after the >$124K "comprehensive" project, the same roof needed to be replaced again. The April 2024 ballot funded $85,000 toward that replacement. The 2024-26 governance turbulence and lender pressure that followed are the next chapter of the same trajectory.

Knott's central observation, in the FCA's narrative passages, is that water and structural concrete cannot be considered separately: "all progressive concrete deterioration mechanisms involve water." The board record, going back to 1996, does not show a board treating them together until the engineer wrote the sentence in 2023.

What this narrative is and is not

This is a documentary synthesis of the minutes record located in Brad's Drive corpus, plus a small set of primary-source correspondence (the July 2022 Bray email, the April 2024 owner ballot, the 2024 board meeting minutes I read directly). It is not an exhaustive accounting — the minutes located cover roughly 1996 forward, with notable gaps at 2000, 2010, 2017-2019, 2020 (COVID), and 2025 (Wix-hosted). The 1992-94 annual meeting PDFs newly added to HT Records Scans on May 9, 2026 will fill in some of the earliest period when re-audited.

This is also not an account of why the boards across thirty years did not connect the two tracks. The minutes record what was said and decided, not why something was not said. Possible explanations range from the absence of in-house engineering capability, to the practical pressure of small annual budgets that made decade-scale horizons hard to commit to, to the documented governance turbulence (three resignations and one removal vote between November 2022 and October 2024 alone). The audit corpus does not adjudicate among those.

What the corpus does establish is that the two tracks, read side by side from 1996 forward, run in parallel and do not visibly meet until October 25, 2023.
