Demolition and Clean-up Activities:
Demolition starts on November 29, 2012.
Work will occur from 8 a.m. - 5 p.m.,
Monday - Friday for about 2 weeks and
should be completed by December 19, 2012.
What are the demolition details and how will
4825 Glenbrook Road be cleaned up?
The U.S. Army Corps of Engineers will remove the
house in accordance with the approved Demolition and Disposal Plan. Details of the plan include
using an excavator to systematically dismantle the interior and exterior of the house from top to
bottom. Dust suppression and noise controls will be implemented. Access to 4825 Glenbrook Road
will be restricted by a safety fence. All access points will remain secured after hours and on
weekends. All debris will be either recycled or disposed of off-site in accordance with local, state,
and federal guidelines.
During removal activities, people can safely walk down the street, and site personnel will direct
traffic on the 4800 block of Glenbrook Road to ensure the safety of all vehicles and passersby.
Construction traffic will be minimal, 1-3 truck loads with construction debris per day. No traffic
detour or lane closures are anticipated, except on the morning of November 29 from 8 a.m. noon.
To ensure the safety of the workers and the community, any part of the house that comes into
contact with subsurface soils, including the basement slab and exterior basement walls, will remain
in place and will be removed as part of the follow-on environmental cleanup action.
The Corps of Engineers will remove the house, cleanup, and restore the property to residential
standards, providing for unrestricted future use of the property. This approach is the most effective
and protective of human health and the environment. This provides the best long-term solution by
minimizing future risk at 4825 Glenbrook Road and providing maximum flexibility in future land use.
