7 structures, including a home, destroyed in Santa Clara, Calif., wildfire

SANTA CRUZ, Calif., Sept. 29 (UPI) -- At least seven buildings, including a home, were destroyed in a wildfire that has claimed some 4,000 acres in the mountains near Santa Cruz, Calif.

The blaze, which is 22 percent contained, also damaged one single-family home. Firefighters said the blaze is burning in "steep inaccessible terrain covered in dry drought-stressed fuel," adding to the difficulty in dousing the flames.

Mandatory evacuation orders were in effect for Santa Clara County, for the Loma Prieta ridgeline area including Uvas Canyon County Park. Evacuation orders and warnings for Santa Cruz County have been lifted. There have been no life-threatening injuries.

Some 325 structures remain endangered as a total of 1,762 personnel work to contain the fire. So far, the fire has consumed 3,849 acres. The cause of the fire is not known.

Southeasterly winds have also caused smoke to waft into the Bay Area, causing poor air quality. The Bay Area Air Quality Management District is recommending the public limit their time outdoors.
