WALNUT CREEK -- Fire crews worked for over a half hour Friday afternoon to contain a small vegetation fire near Walnut Heights Elementary School.

Crews were called to the fire around 3:10 p.m., according to a Contra Costa Fire dispatcher. Firefighters from CalFire were also alerted, but were called off once local units arrived and determined that they could contain the blaze themselves.

The elementary school was not evacuated, and school had already been dismissed for the weekend when the fire was reported.

The fire was contained at 3:52 p.m.

Officials have not yet determined the cause of the fire.

Fire crews are on high alert all over the state as record low levels of rainfall have created dry conditions that provoked a statewide drought declaration from Gov. Jerry Brown on Friday.
