The Town of Edgecliff Village Guide to Trampoline Injury Law and Corporate Accountability

A Saturday afternoon at a trampoline park near the Town of Edgecliff Village often begins with a line of excited children and a parent tapping “I Agree” on a flickering iPad kiosk. It ends, far too often, with what Texas mother Kaitlin Hill calls “the worst scream you could ever hear from a child.” When a three-year-old’s femur snaps because a teenager in a branded polyester shirt wasn’t enforcing age-separation rules, the park’s first move isn’t to apologize—it is to point to the waiver you signed twenty minutes earlier.

We are The Manginello Law Firm, known to our clients throughout Texas as Attorney911. We believe you deserves to know a fundamental truth: a trampoline injury in the Town of Edgecliff Village is almost never an accident. It is the predictable output of a business decision. When a national chain chooses to staff its courts at half the ratio required by ASTM F2970 during a birthday party rush to protect its profit margins, they are choosing to accept the risk that your child will be the next one in a body cast.

Our managing partner, Ralph Manginello, has spent more than 25 years fighting for victims of catastrophic injuries in federal and state courts. We have gone toe-to-toe with Fortune 500 corporations like BP, Walmart, and Amazon. We understand how massive corporate parents—like Sky Zone, Inc. and Unleashed Brands—layer their businesses to hide from accountability. We are not just another personal injury firm; we are a dedicated trampoline injury practice built to pierce those corporate shields.

Why the Town of Edgecliff Village Is at the Center of the Trampoline Risk

The Town of Edgecliff Village sits in Tarrant County, the literal headquarters of the American trampoline park industry. Urban Air Adventure Park is based in Grapevine, and Altitude Trampoline Park is headquartered in Fort Worth. This means that families in the Town of Edgecliff Village live in one of the densest markets for these facilities in the world. From the Urban Air locations in Southwest Fort Worth and Mansfield to the Altitude parks in Cityview and Cedar Hill, Town of Edgecliff Village residents are surrounded by attractions that market “safe family fun” while operating under a voluntary safety floor their own industry lobby wrote.

The DFW metroplex has seen a documented pattern of harm. An investigation by the Fort Worth Star-Telegram uncovered approximately 500 injury reports at 21 area trampoline parks over a seven-year span. In the Town of Edgecliff Village, these aren’t just statistics—they are children being transported to Cook Children’s Medical Center in Fort Worth with injuries that will alter the trajectory of their lives.

The Evidence Clock: Why the Next 7 to 30 Days Are Critical

If your child was injured at a park serving the Town of Edgecliff Village, the clock is not just running on your legal rights—it is running on the evidence itself. Most commercial parks in Tarrant County use digital video recording (DVR) systems that are programmed to overwrite footage every 7 to 30 days.

By day 10, the footage of the double-bounce that launched your son may be gone forever. By day 30, the attendant who was on their phone at the moment of impact may have quit or transferred. Even the waiver kiosk database, which tracks the metadata of the version you signed, may purge its history on a 72-hour rolling cycle.

Our first action for every client in the Town of Edgecliff Village is a 24-hour spoliation demand. We send a formal legal notice to the park operator, the franchisor, and their insurance carrier demanding the immediate preservation of all surveillance angles, original incident reports (before they are “finalized” and sanitized), and training records. We don’t wait for a lawsuit to be filed to protect your child’s case.

Breaking the Paper Shield: Why Your Waiver Doesn’t End Your Case

The most common reason parents in the Town of Edgecliff Village don’t call a lawyer is the belief that the waiver they signed means they “gave up their rights.” That is exactly what the insurance adjusters at the massive parent companies want you to believe. They are wrong.

In Texas, a waiver is a speed bump, not a brick wall. Our associate attorney, Lupe Peña, previously worked as an insurance defense lawyer. He spent years defending recreational businesses and writing the very clauses these parks use. He knows how to dismantle them from the inside.

We attack Town of Edgecliff Village trampoline waivers on three primary fronts:

  1. The Minor-Waiver Rule: Under the landmark Texas case Munoz v. II Jaz, Inc., a parent generally cannot sign away a minor child’s independent legal right to sue for personal injuries. While you may have waived your own claims, your child’s claim in the Town of Edgecliff Village typically survives your signature.
  2. The Gross Negligence Carve-Out: Texas law and public policy do not allow a business to waive liability for gross negligence. If we can prove the park had subjective awareness of an extreme risk and proceeded with conscious indifference—such as knowing a trampoline bed was torn or a foam pit was compacted and keeping it open anyway—the waiver fails completely. This was proven in Harris County when a jury awarded $11.485 million against Cosmic Jump despite a signed waiver.
  3. The Fair Notice Doctrine: Under Dresser Industries v. Page Petroleum, a waiver in Texas must be conspicuous and use express language regarding negligence. If the release was buried in 20 screens of fine print on an iPad, a Town of Edgecliff Village judge may find it legally unenforceable.

The Double-Bounce: The Physics of a Preventable Disaster

The “signature” injury we see in the Town of Edgecliff Village involves the double-bounce. This happens when two jumpers occupy the same trampoline bed. When a 200-pound adult lands while an 80-pound child is pushing off, kinetic energy transfers through the mat, multiplying the child’s launch force by up to 4x.

The child isn’t jumping anymore; they have become a projectile. This mechanism is why ASTM F2970 requires parks to enforce strict age and weight separation. When an Urban Air or Altitude park in the Town of Edgecliff Village area ignores these weights for the sake of higher “throughput,” they aren’t just being sloppy. They are violating the safety standards their own peers wrote.

The $10 Million Rhabdomyolysis Bridge

Our firm is currently litigating a $10 million lawsuit against the University of Houston involving rhabdomyolysis and acute kidney failure. “Rhabdo” is a catastrophic condition where muscle tissue breaks down and spills myoglobin into the blood, poisoning the kidneys.

We see this same pathology in Town of Edgecliff Village trampoline park cases. When a child jumps continuously for 90 minutes in a heated indoor warehouse in the Texas summer, without mandatory hydration breaks, they can arrive at the ER two days later in kidney failure. Most pediatricians in the Town of Edgecliff Village area are only beginning to recognize the link between extended trampoline use and exertional rhabdo. Because we are already litigating $10 million cases in this specific medical field, we have the expert network and the medical litigation architecture ready to apply to your child’s case.

Catastrophic Injuries: Looking Past the Emergency Room Bill

A “broken leg” at a Town of Edgecliff Village trampoline park is rarely just a broken leg. In developing children, fractures often involve the Salter-Harris growth plate. These are cartilaginous zones that, if destroyed, can cause a limb to stop growing or to grow at an angle.

A child injured at age nine might not show the full extent of the damage until age fourteen, when one leg is significantly shorter than the other. Our firm builds cases using a Pediatric Life-Care Plan (LCP). We don’t just look at the ER bill; we work with pediatric orthopedic surgeons and lifecare planners to calculate the next 70 years of medical monitoring, corrective osteotomies, and vocational impacts. We have secured multi-million dollar settlements for traumatic brain injury and spinal cord injury victims, and we bring that same valuation discipline to every Town of Edgecliff Village family.

Holding the “Upstream” Pockets Accountable

Trampoline parks use a layered corporate structure to hide the money. The local operator in the Town of Edgecliff Village area might be a single-purpose LLC with a $1 million policy. That won’t cover a lifetime of quadriplegia care.

We go upstream. We look at the franchisor—UATP Management for Urban Air or Altitude Franchise Holdings. We look at the private equity backers, like Palladium Equity Partners or Seidler Equity. We cite the Damion Collins $15.6 million arbitration award against Urban Air, where the franchisor was held responsible for a “systemic failure” to implement safety changes. If a corporate parent controlled the training, the manual, and the marketing that brought you to the park, we will hold them accountable.

Frequently Asked Questions for Town of Edgecliff Village Families

Can I sue if the injury happened at a birthday party?

Yes. In fact, birthday parties often provide a stronger case because the park is typically at maximum capacity, monitor ratios are at their lowest, and age-mixing is most prevalent. If you were a guest at someone else’s party in the Town of Edgecliff Village, you may not even have a valid waiver on file against your child’s claim.

What if the park says it was my child’s fault?

In Texas, children under the age of seven are conclusively presumed incapable of negligence. Children between seven and fourteen are rebuttably presumed incapable. The park cannot shift the blame to a child for failing to follow rules that the park was being paid to supervise and enforce under ASTM F2970.

How much does it cost to hire your firm?

We work on a contingency fee basis. This means you pay nothing upfront, and we advance every expense—from the biomechanical engineers who reconstruct the accident to the pediatric neurologists who evaluate the long-term impact. We only get paid if we win. Your child’s recovery fund stays intact.

How long do I have to file a claim in the Town of Edgecliff Village?

The Texas statute of limitations is two years from the date of injury. For a minor, the clock is “tolled” until they turn eighteen, effectively giving them until their twentieth birthday. However, as we’ve noted, the evidence disappears in weeks. Waiting years to file is the fastest way to lose a winnable case.
