The first of two open house meetings is tonight for residents to voice their opinions about the rezoning process for Kalahari Resorts & Conventions in Round Rock. The meetings will be 6-8 p.m. tonight and on May 18, at Ridgeview Middle School, 2000 Via Sonoma Trail, Round Rock. City and Kalahari officials will attend both meetings to answer questions and listen to comments from residents. Kalahari plans to invest at least $350 million in building a 975-room hotel with an indoor-outdoor water park, multiple restaurants and a day spa. The property will have a 200,000-square-foot convention center. The 351-acre tract is on the south side of Hwy. 79 east of Kenney Fort Boulevard, across from Old Settlers Park and Dell Diamond. The resort is expected to employ 700 people. City of Round Rock spokesperson Will Hampton said the meetings are informal, come-and-go style. The target opening date for Kalahari is May 2020.
