Crews removed the house (Nov. 29 - 30, 2012) systematically from top to bottom using an excavator. After the demolition, crews began preparing the site for the high probability operations. Historical and field data indicate the high probability areas of the property have a greater likelihood of containing AUES debris and/or glassware items.
Site preparation included low probability test pitting in several areas in the backyard, utility relocation, general site preparations, and installation of the engineering controls needed to safely perform the high probability work. The engineering controls include an Engineering Control Structure (a 60’x80’x27’ tent) that fully encloses the high probability excavation areas,a chemical agent filtration system that will filter the air leaving the control structure, and a continuous air monitoring system. All of the materials removed during the high probability phase will be safely disposed.
Additionally, the Corps of Engineers has developed a Shelter-in-Place program as an added layer of protection to the public.
High probability operations began Sept. 23 and will wrap-up in spring 2015, depending on the types and amounts of debris encountered. The goal is to completely remove any remaining AUES debris and restore the property to residential standards by summer 2015.
