Due to an $11.6 million budget deficit, Rosedale Elementary School was closed in May of 2005. At the time of its closing, it was Denver's smallest elementary school with 131 students at 57% capacity. Two other school closings coincided with the Rosedale closing, Baker and Gove middle schools. The closure of Rosedale was projected to save $300,000 annually for the district.
In 2008, there was a public proposal that Denver Public Schools sell off 8 abandoned school properties including Rosedale, a combined to an estimated property value of $50 to $75 million, to developers in order to earn revenue for the district but DPS did not act on the advisement.
Most of this information I dug up in Denver Post and Rocky Mountain News.
The building was built in 1923 or 1924, and was built in Victorian Gothic Style. It was designed by Jules Jacques Benois Benedict who also designed the Gart Brothers Sports Castle (formerly Cullen-Thompson Motor Co) on Broadway.
