Dore Alley is right around the corner from my office. If you look carefully at the corner of the brick building you will see a steel "bandage" and repairs in the brick walls -- a legacy of the 1989 Loma Prieta Earthquake. Bricks had crashed down denting the cars below leaving gaping cracks in the wall following the mortar pattern between the bricks.
At one time, the "bandage" was black but I guess it was too much of a noticeable reminder of the vulnerability of these unreinforced masonry buildings.
