Teams of workers wielding chainsaws cleared downed power lines and other obstacles from the streets, while forensics teams mobilized to resume their search for human remains in the charred wreckage of the Butte County town of 27,000, which was almost completely consumed by fire last Thursday, just hours after the blaze erupted.
The "Camp Fire" continued to rage in Butte County, about 175 miles (280 km) north of San Francisco, and expanded to 125,000 acres (50,500 hectares), more than four times the area of the city, the California Department of Forestry and Fire Protection (Cal Fire) said.
The death toll stood at 42 people, the most on record from a California wildfire. More than 7,600 homes and other structures burned down, also an all-time high.
Some 228 people are still unaccounted for and listed as missing. Officials asked relatives and friends to keep checking with evacuation shelters and call centers in the hope many of them could be located.
The fire was 30 percent contained, suggesting a "big chunk" was under control, but full containment was not expected until the end of November and the progress would depend largely on the wind and the weather, Cal Fire spokeswoman Erica Bain said.
"Thirty percent is kind of where we're getting close to rounding the corner. When we're the 30s and 40s, they're getting a good handle on it. By the end of this week I'd like to see that number up to 40, maybe 45," Bain said.
A Cal Fire spokesman said firefighters were more optimistic than in previous days, although he warned some populated areas were still at risk because of steep terrain and unpredictable gusts.
"Things look much better than yesterday, due to weather conditions," Scott McLean told a briefing.
One hundred fifty search-and-recovery personnel were due to arrive in the area on Tuesday, bolstering 13 coroner-led recovery teams in the fire zone, said Butte County Sheriff Kory Honea.
The sheriff has requested three portable morgue teams from the U.S. military, a "disaster mortuary" crew, cadaver dog units to locate human remains and three groups of forensic anthropologists.
Some 52,000 people remained under evacuation orders and 8,700 firefighters from 17 states have been battling the wildfires.
In Southern California, two people died in the separate "Woolsey Fire," which has destroyed 435 structures and displaced about 200,000 people in the mountains and foothills near Southern California's Malibu coast, west of Los Angeles.
Authorities were probing the cause of the fires. A spokeswoman for the California Public Utilities Commission said on Tuesday the regulator has launched investigations that may include an inspection of the fire sites once Cal Fire allows access.
PG&E Corp, which operates in northern California, and Edison International, the owner of Southern California Edison Co, have reported to regulators that they experienced problems with transmission lines or substations in areas where fires were reported around the time they started.
President Donald Trump on Monday night declared a major disaster exists from the fires, making federal funds available to people and local government agencies in Butte, Los Angeles and Ventura counties.
The pledge came two days after Trump blamed the brush fires on forest mismanagement, tweeting "Remedy now, or no more Fed payments!"
