Mudslide on Los Altos Road


A large mudslide left a portion of Los Altos Road between Highway 41 and San Marcos Road in Atascadero covered in mud on Friday.

Even though a portion of the road is impassable to through traffic,  all residents have access to their properties. Because the slide is active, the city is assessing the damage and future plans for debris removal and repair.

City staff is asking motorists to use the following detours:

  • San Gabriel Road – Monita Road – Sierra Vista Road – San Marcos Road
  • Santa Lucia Road – Laurel Road – Cenegal Road – San Marcos Road
