Rust-colored stains have marred Texas' tallest building in Austin. Here's why.
Austin residents are accustomed to seeing changes in the city’s skyline, but Texas' tallest tower is drawing attention for an off-color reason.
Large, rust-colored stains running down the white and glass exterior of Waterline, the 74-story mixed-use tower under construction in the Rainey Street District, are drawing speculation from passersby and social media users about what’s happening to the city’s new marquee structure.
It’s nothing to worry about, according to an executive with Lincoln Property Co., which is developing the building.
