Workers for Renner Sports Surfaces apply the surface coat at the Apple Valley Park tennis courts in Paonia Monday morning. Lisa Cook, president of the North Fork Pool, Park and Recreation District, said that several factors, including weather, will determine the opening day, but that it will just be a matter of days. Construction was originally scheduled to be completed by mid-July. The opening will be posted on the district’s website, northforkrecreation.com, and on the Paonia Facebook message board “as soon as we know for sure,” said Cook. A grand opening will be held in the near future.
