It's not unusual for developers to clash with preservationists when trying to get projects completed. But in the case of the River Oaks Shopping Center in Houston, the protest this time has been to save the 68-year-old center. A number ofin the city have posts arguing to preserve a portion of the center and the nearby Alabama Theater, an example of Art Deco design. Some Houston blogs are even giving frequent updates of the property's demolition. There's also an online petition with 25,770 signatures. According to owner Weingarten Realty's site, the property is being redeveloped to include a new Barnes & Noble and 23,000 square feet of new restaurant and retail space.
