Living on top of the volcanic bench
The Westside is one of the most geologically distinct parts of the Albuquerque metro. It sits on the West Mesa — a broad volcanic bench that rises sharply above the Rio Grande valley, capped in places by basalt flows from the Albuquerque Volcanoes and finished with layers of wind-blown sand, gravel and caliche. Subdivisions like Ventana Ranch, Paradise Hills, Volterra, Taylor Ranch and The Trails were built by cutting into this mesa and finishing lots on engineered fill so pads could sit at a workable grade. What most Westside homeowners are watching move under their driveways and patios today is that fill, not the native mesa underneath it. Native ground is dense and stable; the compacted top layer keeps consolidating for a decade or more after the home is built, which is why so many Westside repair calls come from homes 10 to 25 years into their life.
