CHIPPING AWAY AT THE MUSEUM DISTRICT Those little tree topper signs have been up throughout the larger neighborhood for a while now, but the new Boulevard Oaks Historic District was only approved by City Council this week. The designation means you’ll now have to wait 90 days before you can demolish that rambling South Blvd. mansion you just picked up. At the same meeting, council members approved an 8-acre extension to the Midtown TIRZ that takes a bite out of the Museum District. The area includes the new locations of Asia House, the Buffalo Soldiers Museum, and the Museum of African-American Culture. [Houston Chronicle, via Slampo’s Place] Photo: WhisperToMe
