Future Of 2 Large Riverside County Waterparks In Question After 'Permanent Closure' Announced

PERRIS, CA — Operators of DropZone Waterpark in Perris announced that the facility is permanently closing after a decade of operation, sharing the news in a weekend post across the venue's official social media accounts.

It's not the only closure.

"After 10 incredible years of proudly managing DropZone Waterpark for Riverside County, it is with heavy hearts that we share the news that DropZone Waterpark will be permanently closing," the statement read.

"Over the past decade, we have had the privilege of welcoming countless families, celebrating birthdays, watching children grow up, and creating unforgettable summer memories.

"To our amazing staff, loyal guests, and the Riverside County community — THANK YOU! Your support, dedication, and enthusiasm made every summer special.

"While we are saddened to see this chapter come to an end, we are incredibly grateful for the friendships, laughter, and memories that will last a lifetime.

"The gates may be closing, but the memories will live on forever."

The message was signed, "With heartfelt gratitude, The StandGuard Aquatics Team."

The 12-acre park at 2165 Trumble Road, just off Interstate 215, is owned by Riverside County and has been managed by StandGuard Aquatics Inc. under a 10-year agreement signed in April 2017. StandGuard has also overseen operations at the county-owned Cove Waterpark in Jurupa Valley, according to that contract.

On the official Cove Waterpark Facebook page, a Sept. 8 post noted that the facility had closed for the summer 2026 season. "See you in 2027," the post stated.

Patch reached out to county officials for comment Tuesday. In an emailed response, Riverside County spokesperson Yaoska Machado said the two waterparks have historically operated seasonally for approximately four summer months a year and are mostly closed for the remainder of the year.

There is no renewal in 2027 on the 10-year agreement with StandGuard Aquatics for operation and maintenance of the two parks, Machado said.

"Due to the rising costs of operations, the County is currently looking at alternative options for future use and transfer of all or part of these seasonal facilities," Machado's statement continued. "At the same time, the County is considering the highest and best use and transfer to other local and public agencies or districts that are better positioned to operate waterparks and community pools while generating revenue to offset costs."

The county is expected to announce future plans for the waterparks over the next few months, Machado said.

The $24 million DropZone Waterpark was originally known as the Perris-Menifee Valley Aquatic Center when it opened to the public on May 24, 2014, according to the city of Perris website.

"It was the realization of a dream for Riverside County officials and a much-needed recreational opportunity for residents of all ages," the city's website states.

The complex features a 50-meter competition pool equipped with an integrated timing system, electronic scoreboard, and spectator grandstands, alongside public deck space. Other park amenities include two large water slides, the Lil’ Jumpers splash area, the Meridian Springs shallow play area, a lazy river, a FlowRider wave simulator, beach volleyball courts, a snack bar, covered dining spaces, banquet rooms, and cabana rentals.
