The Lofty Castle Skytower by Moduplay has been approved by Yass Valley Council as part of the park's new playground design.

The design will also include a maze, animal puzzle, musical chimes, whirly rope, flowers, voice tubes, shopfront, timber stepping bridge, drum, xylophone and curved mirror.

Members of the public were invited to have their say in May about what they'd like to see incorporated in the park and the pieces of playground equipment with the most votes were selected.

The council signed off on the design as its ordinary meeting on June 26.

All councillors were in favour, except for Cr McManus and Cr Abbey who was absent.

Cr McManus said he couldn't support the installation of the new slide because there was "nothing wrong with the old one."

"Generations of Yass people have loved the existing slide and I don't think there is anything wrong with it," he said.

The council decided in February that the park's iconic spiral slide and other playground equipment would be removed later this year.

The slide has been non-compliant since 2016 and the rest of the equipment recently expired its 15-year life-span, according to the council.

The council will replace the playground equipment with a $130,000 NSW government grant and $130,000 of its own money.

Cr Jones said some residents had expressed the price tag was too high and that the money could be better used elsewhere.

However, the conditions of the government grant were that it was spent on the park and that the council matched it.

One resident said that soft fall should be installed at the playground, but the council's general manager Sharon Hutch said it was too expensive and could possibly cost more than the equipment.

Another resident said they wanted a flying fox installed at Coronation Park, but the council's director of engineering Stan Robb said the park was too small.

"A lot of families go out to the park in Boorowa, which has a flying fox," Cr Jones said.

"Coronation Park isn't right for that but there might be other places," she said.

Mr Robb said there was an intention to look at other areas for larger playground equipment to be installed, such as a flying fox.

"There are a number of other parks that could do with some upgrades," he said.

As for the future of the existing spiral slide, Yass High School students have been set the challenge of turning it into a piece of art so its life in the town can continue.

The current playground will close from October 2019 for the new equipment to be installed and re-open before school holidays in December 2019.
