The Palisades and Eaton fires, two of the deadliest and most destructive wildfires in California history, reached 100 percent containment more than three weeks after they began.

After nearly a month, the Palisades and Eaton fires in Los Angeles County have reached 100% containment, according to the California Department of Forestry and Fire Protection. The two blazes started on Jan.

Those looking to assist residents affected by the Los Angeles County firestorm have a number of options to donate money, materials or their time.

Containment measures the percentage of a fire's perimeter that firefighters have under control. Parts of the fire's interior may still be burning.

The Eaton Fire is almost completely contained in the Altadena area northeast of Los Angeles. On the LA County coast, the Palisades Fire is over three-fourths contained. The Hughes Fire, which broke out in the Lake Castaic area Wednesday north of Los Angeles, is over 50% contained.

As Los Angeles recovers from its devastating wildfires, environmental engineers, urban planners and natural disaster experts are casting forward with visions of what could come next for neighborhoods that have been reduced to ash and rubble.
