Pflugerville's Hawaiian Falls Water and Adventure Park is unlikely to open in its entirety by Memorial Day weekend as originally hoped.

At a public dedication ceremony May 8, Hawaiian Falls CEO David Busch said only parts of the park are likely to be open on schedule. A full opening could be delayed until the first week of June.

In addition it is likely that only season pass holders will be admitted to the park for its first few days of operation. Busch said that is a gesture to the customers he said will form the backbone of the park's clientele.

Hawaiian Falls has sold roughly 2,400 reduced-price season passes to Pflugerville residents since early December. The park has roughly 600 left to sell for the 2014 season.

The park is located on the southbound SH 130 service road just south of the intersection of FM 685 and SH 130.

Park officials cannot guarantee an exact date for Hawaiian Falls' full or partial opening because construction is ongoing. Poor weather could also extend the delay.

"We're really waiting got see what happens over the next week to 10 days," Hawaiian Falls spokesman David Alvey said.

The park's wave pool and lazy river should be ready by the proposed partial opening on Memorial Day weekend, Busch said. Several water slides could also be open if construction goes as planned.

Busch said all the park's water features will be "in full swing" by the first week of June—the start of many area schools' summer vacation seasons. The opening of the Hawaiian Falls Adventure Park, the facility's dry play area, is likely to trail the opening of the water park by at least a day, Busch said.

Plans for the park were finalized last summer, but construction did not begin until December because of financing delays. In addition, construction crews have lost 28 working days to inclement weather since December.
