Description:
The popularity of Southern California's most destructive curbside shade tree is starting to bounce back--thanks to rubber sidewalks.
Leafy ficus trees have helped cool neighborhood roadsides for decades. As they have grown, though, their stubborn roots have created safety hazards by pushing concrete sidewalk slabs out of the ground.
That has prompted repair crews throughout the region to chop down rows of the dense, green-canopied trees. Replacement trees have generally been slower-growing and scrawnier-looking.
But street maintenance workers in Southern California will soon be stretching the life expectancy of the ficus by using flexible sidewalks made from recycled automobile tires.
