Derelict Housing Structures

Multiple Locations – Colville Reservation

On the Colville Indian Reservation, a number of abandoned residential and commercial buildings were identified for demolition or redevelopment. Before any demolition could begin, inspections were conducted to identify hazardous materials commonly found in older structures.

These inspections focused on materials like asbestos, lead-based paint, and electrical or lighting components that may contain harmful substances. Additional materials tested included:

• Wood, glass, concrete, and metal

• Fiberglass insulation and flooring

• Roofing, piping, and ducting

• Railings and plumbing

The purpose of these inspections was to determine the presence of hazardous building materials and help guide the safe handling, disposal, or treatment of these items before demolition. This process also supports proper waste characterization, in line with environmental and safety regulations.

By identifying these hazards early, the Colville Tribes ensured that modernization and redevelopment activities could move forward safely, while protecting workers, nearby residents, and the surrounding environment.
