A LIFEBOAT FOR THE ROYALTON’S CORRODING CROWN? Judging from court filings, there appears to have been some sort of resolution to the lawsuit filed more than 2 years ago by the condominium association of the 253-unit Royalton at River Oaks highrise over the design of the steel grid at the top of the building at 3333 Allen Pkwy. The lawsuit claimed the structure was corroding and was designed in such away that made maintaining it or recoating it impossible — and sought damages from the building’s contractor, architect, and other parties. The condo association dropped its claims against many of those parties late last month. And a reader wonders if the attachment seen hanging below the structure in the recent photo at left, which “almost looks like a hot tub,” is part of some newly devised cleaning solution.
