Las Vegas (KTNV)-After 13 investigators asked him to inspect the holes, turf, and exposed substratum that we found, artificial turf experts said that parts of the four urban football stadiums were very dangerous.

After our investigation was broadcast, the city of Las Vegas installed a big patch to replace the goal frame.

Patches are fresh, and these areas are better and safer than before, but experts will tell you...this is far from enough.

"When it becomes so thin, the product will be beaten to death, now is the time to replace it," Joe Wardkins said after inspecting the relevant fields.

Wadkins is JW and is considered one of the world's leading synthetic turf experts.

He helped us inspect the City Stadium in Ed Fountain Park on Decatur Avenue and Vegas Avenue, and the Kellogg Zach Football Stadium on Washington Avenue and Buffalo Avenue.

"This material has no more strength. It is less than half an inch thick, and you have lost all of the filler, which allows you to simulate natural grass," JW said.

The goal frame and penalty points were severely damaged, where compacted rock and soil as hard as concrete were exposed.

After our story aired, local athlete Sasha Pina sent an email to share her story.

In 2010, 16-year-old Sasha was a rising college star, but her football career came to an abrupt end on the grass of Kellogg Zaher.

She suffered a traumatic brain injury after falling head-on on the court.

Sasha wrote: "I saw your story about a turf football field. I have played football in Las Vegas since I was 7 years old. I grew up playing football here, and I participated in many games while playing club football. Championship. In September 2010, Labor Day weekend, I played a game on the grass of Kellogg Zaher. In that game, I went up to the goal with a header, and when I came down, I fell head-down to the ground. , Unconscious. In the hospital, they told my mother that I had a skull fracture, a concussion of level 3, and a brain swelling. Because of that game, I could no longer participate in the game. At the time I was 16 years old and the college coach looked at me. We believe that even though At that time, the turf field also had the problem of lack of fillers, rocks and concrete below, which made it very dangerous.

This is something I hope Manchester City will pay more attention to. I hope that no other athlete will be seriously injured because of the lack of care for the venue we love. "

As reported by 13 Investigates in October, Kellogg Zaher's venues 6 and 7 were installed in the summer of 2013. This means that they are officially beyond the warranty period. In the field of artificial turf, the end of the warranty period is equivalent to the end of the service life.

New York City does not plan to replace the Kellogg Zaher oil field or the two Ed Fountain oil fields (with warranty starting this winter) before September 2023, but choose a cheaper patch.

"When they install an oil field for the first time, they should keep a monthly reserve, so that at the end of the oil field’s cycle, they will have the money to replace it at the bank without having to continue repairs. The service life of the patch is related to the The turf is just as good," JW said.

The city government stated that the cost of replacing each oil field is approximately US$375,000.

Leaders have eight years to budget for this, plus the recent influx of US$130 million from the US rescue plan.

Some of these funds can be used to fund new areas.
