Prairie Village skate park concrete deterioration ‘rapidly getting worse’

Cracks in the concrete at the Prairie Village skate park are consistent with the alkali-silica reaction.

The skate park completed in the Harmon Park space next to the Prairie Village Police Department is showing significant signs of deterioration and will likely need to be reconstructed soon, say city Public Works officials.

Public Works director Keith Bredehoeft told the city council in the course of its ongoing 2015 budget deliberations that they might need to consider funding major repairs or reconstruction of the facility in the next few years.

The department has been tracking growing cracks in the skate park concrete for some time, but the deterioration has accelerated rapidly in the past months. Bredehoeft said the deterioration is consistent with a problem known as the alkali-silica reaction (ASR).

“This cracking is not isolated as it is showing of pretty much everywhere at the skate park,” Bredehoeft said. “It is a problem with concrete that was placed 10 to 15 plus years ago. ASR is always a concern with concrete but, unknown at the time, the limestone ledge being supplied by the quarries back then apparently made the problem worse.”

The Prairie Village skate park was completed in 2005 at a total cost of approximately $230,000. Bredehoeft said the city does not have a sense at this time how much it would cost to reconstruct the facility.

The cracks are visible throughout the park.
