The opening of the Barclays Center hasn't been without its challenges. Even after most of the ideological debate—lawsuits over eminent domain stalled the project for years, affordable housing advocates vociferously protested the development—dissipated in the wake of the arena's opening, structural issues remained. The designers stipulated that the arena be built with Cor-Ten, a weathered steel that may be too unstable to coat a sports arena. Those rusty brown panels have already "dripped orange blossoms onto the sidewalk." Recently, 8% of the bolts that join the panels to the stadium needed to be replaced only three months after the arena opened; it was not a sure thing that the panels could withstand Hurricane Sandy.
