Sidewalk damaged by roots.
Roots removed and slab re-poured.
NOTE: In some areas of Los Angeles there area actually two sidewalks. This particular one had an old sidewalk from the 1920's 8 inches below the damaged one from the 1950's. It was once a common practice for "public works" to elevate streets and sidewalks by simply pouring one on top of another. The space between the sidewalks was filled with dirt in time roots began to make their way in and grow. With no way for the roots to grow downward, because of the old concrete side walk blocking it's way, the roots simply grew upward severely damaging the top sidewalk.
