Some of the key progress includes: - Continued monitoring shows no impacts to biological activity and stormwater/ground surface is protected - Salvaging of up to 25 corrugated windows for historic mitigation - Scaffolding has been installed and mansard panels, redwood siding, and windows have begun being removed - Coating inspections and touch-ups are ongoing - The schedule calls for completing fieldwork and confirmation sampling in Spring 2012 and submitting the final report in Summer 2012.
