Wal-Mart director of communications William Wertz confirmed the store’s location in a July 1 email. Construction is already underway at the site and there is no official opening date yet, but the store will be approximately 40,000-square-feet, Wertz said. Houston-based Warwick Construction is managing construction. The company is also building two retail buildings, each 10,000-square-feet, adjacent to the future Wal-Mart Neighborhood Market, said Bill Chenel, senior project manager for Warwick Construction. The retail sites are not fully designed yet and the company is still waiting on final renderings of the project, Chenel said. No construction timeline has been released, but Chenel said the store could open as early as November.
