Demolition of 8787 Georgia Ave., the former home of the county’s Planning Department, is slated to begin by the end of the year in preparation for a 2021 groundbreaking of the redevelopment of the property. The county chose partners Bozzuto and StonebridgeCarras in 2013 for a two-part redevelopment effort, according to Devon Hastie, development manager for Bozzuto. The first part, construction of a new office building for the county in Wheaton, has been completed.
