Neither the threat of rain nor the likelihood of a delayed park opening was enough to dampen the spirits of Pflugerville residents who attended a May 8 dedication ceremony for the soon-to-be-open Hawaiian Falls water park.

Hundreds of guests turned out for the park's dedication ceremony and pool signing, in which the public was invited to write or draw on the bottom of the park's 18,000-square-foot wave pool before its concrete is sealed.

The park's construction has been delayed repeatedly by winter weather, and Hawaiian Falls CEO David Busch said opening day could be pushed to early June.

The dedication ceremony included speeches by officials from the City of Pflugerville and the Pflugerville Community Development Corporation, which both played significant roles in developing and financing the park. Pflugerville City Manager Brandon Wade said the park will be the "anchor of family entertainment" in the city.

The $21.5 million, 25-acre facility is expected to attract more than 300,000 guests in its first year of operation and create 300 seasonal jobs.

Park employees also led attendees in a group prayer to bless the facility. The stated mission of Hawaiian Falls, which runs several water parks in Texas, is "serving the lord by bringing families closer together."
