The proposed sprayground at Virginia Highlands Park is behind schedule and likely will not open until next year.

County officials say the project schedule has been extended while they take “some additional measures to ensure cleaner water enters the storm sewer from the sprayground.” That may be a disappointment to residents who were hoping to have a new place for their kids to cool off this summer.

We reported in 2010 that the sprayground — the county’s most elaborate water park yet — was originally scheduled to open by Memorial Day 2012. Now, we’re told, the county hopes to begin construction late this summer, which will allow the sprayground to open on Memorial Day weekend 2013.
