A Saturday afternoon in the City of Kemah often looks like families gathering for a day of sun at the boardwalk or a birthday celebration at one of the massive adventure parks serving the Galveston County area. You see kids running toward the brightly colored nylon mats of a trampoline court, their eyes wide with excitement. You sign the document on the iPad kiosk because the line is long, your child is eager, and the facility feels like a professional, safely managed environment.

Then, the scream happens. As Kaitlin “Kati” Hill told ABC News after her three-year-old son Colton was injured, it is “the worst scream that you could ever have heard from a child.” In an instant, a fun weekend in the City of Kemah becomes a blur of ambulance lights, emergency room waiting areas, and a pediatric orthopedic surgeon explaining that your child’s femur is shattered or their growth plate is destroyed.

At Attorney911, we know that what happened to your family wasn’t just a “freak accident.” Whether the injury occurred at an indoor park like the Urban Air serving the Bay Area and the City of Kemah or on a backyard trampoline in a neighborhood near the 146 corridor, it was the result of a system. For over 25 years, Ralph Manginello has been making corporate defendants pay for the consequences of their business decisions. Our firm’s managing partner, admitted to the Southern District of Texas, brings federal court experience and a history of litigating against Fortune 500 giants like BP to the fight for your child’s recovery.

When a City of Kemah park decides to staff its courts with a 1:60 monitor-to-jumper ratio instead of the industry-standard 1:32 just to hit a profit target, that is a business decision. When a manufacturer like Jumpking or Skywalker sells a product against 25 years of American Academy of Pediatrics (AAP) warnings because it is profitable to do so, that is a business decision. We are here to hold the people who made those decisions accountable.

The Business of Risk in the City of Kemah

The commercial trampoline industry in Texas is an unregulated frontier. While you might assume the state inspects these facilities, the truth is that Texas has no specific trampoline park safety law. Under Texas Occupations Code Chapter 2151, the state regulates “Class B” inflatable rides—things like bungee trampolines or indoor zip-coasters—but the main trampoline decks themselves are statutorily excluded. This regulatory gap means that parks in the City of Kemah operate only to the standards they choose to follow.

Most personal injury firms handle a trampoline case like a typical slip-and-fall. We don’t. We built our practice around the understanding that these are complex corporate-accountability matters. Our associate attorney, Lupe Peña, used to sit on the other side of the table. He spent years defending insurance companies and recreational businesses against the exact types of claims we now bring. He knows which waiver clauses a Texas judge will throw out and which defense tactics an insurance adjuster will try first. He is also a native Spanish speaker, representing our clients directly without the need for an interpreter.

If your child is currently at a trauma center like UTMB in Galveston or Texas Children’s in Houston, the medical bills are already mounting. But your case is about more than just the hospital bill. It is about a lifetime of care, potentially lost earning capacity, and the emotional trauma of a family’s life changed in one bad landing.

Why Your Child Was Injured: The Physics of Negligence

Trampoline injuries are driven by physics that the industry has understood for decades. The most common mechanism is the double-bounce. When a 200-pound adult lands on a trampoline mat at the same moment a 60-pound child is pushing off, the energy transfer can multiply the child’s launch force by up to 4x. The child isn’t jumping anymore; they have been turned into a projectile.

ASTM F2970 is the safety standard that the trampoline park industry itself drafted to establish a safety floor. It requires parks to operationalize age and weight separation to prevent these very collisions. When a park in the City of Kemah fails to enforce these rules on a crowded Saturday afternoon, they aren’t just being “careless.” They are violating a standard their own peers wrote because they know how dangerous the equipment can be.

The American Academy of Pediatrics has been warning parents since 1999 that trampolines do not belong in a recreational environment. Yet, families in the City of Kemah see marketing for “Toddler Time” and birthday party packages that imply total safety. At Attorney911, we use these standards—ASTM F2970 for commercial courts and ASTM F381 for backyard equipment—as the baseline to prove that the park or manufacturer breached their duty of care to your family.

The Waiver Is Noise, Not a Wall

The first thing an insurance adjuster will tell a City of Kemah family is, “You signed a waiver, so you have no case.” This is a lie designed to make you walk away. In Texas, the waiver is a speed bump, not a wall.

Under the landmark Texas rule in Munoz v. II Jaz, Inc., a parent generally cannot sign away a minor child’s personal injury claim in advance. Even if you signed that iPad kiosk agreement, your child’s right to seek justice for their own injuries remains intact. Furthermore, Texas follows the Dresser Industries v. Page Petroleum “fair notice” doctrine. If the waiver wasn’t conspicuous—meaning the language wasn’t bold, set apart, or clearly stating it released the park’s own negligence—it may be entirely unenforceable under Texas law.

More importantly, no waiver in the United States covers gross negligence. If a park knew about a torn mat and failed to fix it, or if they knowingly understaffed a high-risk area like a foam pit, the waiver stops applying. We point to cases like the $11.485 million verdict against Cosmic Jump in Harris County. In that case, a 16-year-old fell through a torn trampoline slide onto concrete. The jury found gross negligence, and the signed waiver did nothing to protect the park from an 8-figure judgment.

Your child’s case is decided by what gets preserved this week. Call us at 1-888-ATTY-911. Hablamos Español. Our spoliation letter goes out within 24 hours of your retention to freeze the evidence.

Catastrophic Pediatric Injuries and Lifetime Damages

A “broken leg” in a developing child is not the same as a broken leg in an adult. At your child’s age, their bones are still developing through growth plates known as physes. A Salter-Harris Type II fracture at age eight can lead to a limb-length discrepancy that doesn’t fully manifest until age fourteen. By then, without a lawyer who understands pediatric orthopedics, the connection to the City of Kemah trampoline accident might be difficult to prove.

We also see children suffering from SCIWORA—Spinal Cord Injury Without Radiographic Abnormality. Because a child’s spine is more flexible than an adult’s, the cord can be stretched and damaged even when the X-ray or CT scan looks normal. If your child was told they just had a “panic attack” after a foam pit landing, like in the viral Elle Yona case, they may actually have a vertebral artery dissection or a spinal-cord stroke.

Our firm is currently litigating a $10 million university lawsuit involving rhabdomyolysis and acute kidney failure. This is the same muscle breakdown that can occur after a child jumps for ninety minutes straight in a hot, poorly ventilated City of Kemah-area park without proper hydration. We have the medical experts and the trial experience to document these complex injuries and ensure the insurance company pays for the actual lifetime cost of recovery.

Your Job as a Parent: Preservation and Action

If your child was injured in the City of Kemah, you are likely feeling an immense amount of guilt. You think, “I shouldn’t have let them go.” We are here to tell you: none of this was your fault. You were a paying customer who expected the park to follow the safety standards. The park is the party that failed its duty to train attendants and maintain equipment.

Your only job now is to protect your child and their future. This requires moving faster than the park’s risk management team. Surveillance DVR systems at these parks often overwrite footage in as little as 7 to 30 days. The incident report you filled out might be “revised” on the park’s computer system by the time a lawsuit is filed. We send a comprehensive litigation-hold demand to every corporate entity involved—the operator, the franchisee, and the national franchisor like Sky Zone or Urban Air—to ensure that footage, training logs, and digital metadata are protected.

Identifying the Five-Layer Defendant Stack

When we build a case for a City of Kemah family, we look upstream. We identify the operator LLC, the franchisee holding company, the national franchisor (like Urban Air Franchise Holdings), the corporate parent (such as Unleashed Brands), and the private equity sponsor behind the chain. We do this because the local operator often carries a small primary insurance policy that won’t cover a catastrophic injury. The real money is held in the corporate excess towers and umbrella layers that we know how to find.

We’ve gone head-to-head with some of the largest corporations in the world. The fleets of lawyers hired by national trampoline chains don’t intimidate us. We have recovered multi-million dollar results for victims of traumatic brain injuries, amputations, and spinal cord damage by refusing to settle for the “primary policy limit” shell game.

The Evidence Clock Is Ticking in City of Kemah

In Texas, the statute of limitations for personal injury is two years. For a child, that clock is paused until they turn eighteen. But waiting is the most dangerous thing you can do. By the time many parents think about hiring a lawyer, the attendant who saw the accident has quit, the foam pit has been refilled, and the security footage is gone forever.

A case starts with one phone call. We work on a contingency basis, meaning you pay nothing upfront and nothing at all unless we win. We advance the costs for the biomechanical engineers, the pediatric specialists, and the ASTM compliance experts needed to win this fight.

Call 1-888-ATTY-911 today. Whether you are in the City of Kemah, League City, or anywhere in Galveston County, we are ready to take your call 24/7. Hablamos Español. Our Texas offices in Houston, Austin, and Beaumont serve as the base for our national practice. We protect families. We protect children. We make the system pay.

Navigating the Galveston County Legal Landscape

Families in the City of Kemah often find themselves caught between different jurisdictions. An accident might happen at a park in Webster or League City, but the case might need to be filed in the Harris County or Galveston County courts. Knowing where to file can be the difference between a jury that understands the value of a child’s spine and one that is defense-friendly.

Ralph Manginello’s federal court experience and admission to the Southern District of Texas mean we are prepared to handle your case wherever the corporate structure dictates it belongs. We analyze the franchise agreements of chains like DEFY or Altitude to see if they try to force families into arbitration—and we use the 2025 Pennsylvania Supreme Court precedent in Santiago v. Philly Trampoline Park to argue why your child’s right to a jury trial should never be signed away by a parent.

The Hidden Hazards of Backyard Trampolines in Kemah

While the bright lights of the adventure parks are a major source of injury, many City of Kemah families deal with accidents in their own backyards. In a coastal environment like Galveston County, the salt air and high humidity accelerate the degradation of trampoline equipment. A safety net that looks fine may have lost half its tensile strength due to UV exposure and salt corrosion.

If your child was injured on a neighbor’s trampoline, you might be worried about the social consequences of a lawsuit. But these claims are almost always about accessing the homeowner’s liability insurance or pursuing the manufacturer. We know that Jumpking, Skywalker, and the “Bouncepro” brand sold by Walmart have long histories of CPSC recalls for frame weld breakages and netting failures. We hold the manufacturers accountable for selling defective products to City of Kemah families.

Frequently Asked Questions for City of Kemah Families

Can I sue if I signed the waiver at a park near the City of Kemah?

Yes. As we discussed, Texas law is very protective of children. Under Munoz v. II Jaz, a parent’s signature generally cannot waive a minor’s right to sue for their own injuries. Furthermore, if the park was grossly negligent—such as ignoring a known equipment defect—the waiver is essentially useless as a defense. We have successfully navigated these waivers for over two decades.

How much is my child’s trampoline injury case worth?

The value depends on the permanent nature of the injury. A Salter-Harris growth plate fracture that leads to a decade of monitoring and corrective surgery can anchor a settlement in the $500,000 to $2 million range. Catastrophic spinal cord injuries resulting in paralysis often see awards or settlements of $5 million to $15 million or more, because they require a lifetime of attendant care and medical management. We work with life-care planners to calculate every dollar your child will need for the rest of their life.

What should I do if the park manager tells me not to call 911?

Call 911 yourself immediately. Multiple public reviews of parks like Urban Air in Southlake and other Texas locations allege that staff are instructed to downplay injuries and discourage emergency calls. This is a tactic used to buy time while witnesses leave and video is overwritten. Never let a park employee dictate your child’s medical care.

The insurance company offered to pay my medical bills. Should I take it?

No. This is likely “Med-Pay” coverage, which is often tied to a full release of all future claims. If your child’s injury turns out to be a lifelong condition—like a growth plate arrest or a TBI—you will have signed away your right to recover the millions of dollars they actually need. Always have a lawyer review any document before you sign it.

How long do we have to file a claim in Texas?

While you have until age 20 to file for a minor’s injuries in Texas, the evidence vanishes in weeks. You should contact us within the first seven days to ensure we can freeze the surveillance video and secure witness statements while memories are fresh.

Proving Liability in Multi-Attraction Parks

Modern parks in the Galveston County area are no longer just trampolines. They are family entertainment centers with go-karts, ziplines, and climbing walls. The 2025 fatality of Emma Riddle at an Urban Air in Port St. Lucie involved a go-kart mechanical failure, proving that these bolted-on attractions can be even more dangerous than the courts themselves.

Whether your child was hurt on a Sky Rider indoor coaster or fell thirty feet from a climbing wall because an attendant didn’t attach the harness—like the Lakhani case in Sugar Land—we treat these as separate counts of negligence. We identify the manufacturer of the specific attraction, such as Ropes Courses, Inc., and include them as a defendant alongside the park operator. This comprehensive approach is how we ensure that no matter who holds the primary responsibility, there is an insurance policy that will respond.

The Cost of Waiting Is Too High

Every minute you wait to hire an attorney is a minute the park’s corporate lawyers spend building their defense. They are already analyzing the waiver you signed and checking to see if their DVR has already “recycled” the footage of your child’s fall.

We are ready to start building your case today. I have spent my career making sure that families in the City of Kemah don’t have to face these corporate giants alone. We provide the technical expertise, the medical specificity, and the aggressive trial preparation that forces insurers to take your child’s case seriously.

Call us at 1-888-ATTY-911 or visit our Houston, Austin, or Beaumont offices. The consultation is free, and we advance every cost. Your child’s future is worth more than a piece of paper they signed at a front desk. Let us prove it to you.

A Systemic Failure, A Path to Justice

What happened to your child wasn’t an accident—it was the predictable output of a system. The AAP has been warning about trampolines since 1999. ASTM F2970 was written by the trampoline park industry itself to establish a safety floor. The park operated below that floor to hit a margin target. The waiver was drafted by corporate counsel who knew it wouldn’t hold in a Texas courtroom. The surveillance is engineered to overwrite before most families have a lawyer.

Attorney911 was built for exactly this fight. Ralph Manginello brings 25+ years of catastrophic injury and federal-court experience, including litigation against BP and the University of Houston. Lupe Peña used to defend recreational businesses and insurance carriers from the inside—he knows which waiver clauses hold and which ones break. Our 50-state database tracks exactly how Texas treats parental pre-injury waivers, comparative negligence, and statutes of limitations. Our UH rhabdomyolysis case uses the same medical experts and the same institutional-accountability framework applicable to trampoline crush and extended-exertion injuries.

Your child’s case is decided by what gets preserved this week. Surveillance DVRs overwrite in 7 to 30 days. Waiver databases purge on cycles as short as 72 hours. Attendants transfer. Foam pits refill. Incident reports get “revised.” In Texas, the statute of limitations on your child’s personal injury claim runs two years from the date of injury, tolled to age 20 for minors. We file fast. We don’t wait.

Call 1-888-ATTY-911. Hablamos Español. No fee unless we win. We advance every expense—biomechanist, pediatric orthopedic surgeon, ASTM compliance expert, life-care planner. Your child’s recovery fund stays untouched. Our spoliation letter goes out within 24 hours of your retention. The case starts today.
