Development Over Closed Landfills

There are many closed or abandoned landfills in the Austin area. Many operated before landfills were regulated and may pose environmental or safety risks. Their boundaries are often unknown or poorly defined. Structures built over landfills may be at risk from soil subsidence or methane gas.
