In recent months, Cal OES hired contractors and consultants to backfill some over-excavated lots and to assess and repair damaged properties.
According to the letter, in Sonoma County alone they found:
- 600 reports of overscraping
- 80 additional properties that are so over-excavated a major engineering fix will be required
- 260 properties with other damage to septic systems, wells, driveways, and retaining walls
- 12-plus sites cleared by USACE still contaminated by ash and fire debris
Mike Peterson, Chief of Public Affairs for the Army Corps' South Pacific Division, said Colloton would need to coordinate with FEMA before responding formally to Ghilarducci's letter.
Peterson said while he understands that some homeowners have outstanding issues, the size and scope of the cleanup project was massive, and that Army Corps' personnel worked 12-hour days, seven days a week to complete the removal of 1.7 million tons of debris from Sonoma, Lake, Mendocino and Napa Counties.
"We're looking at houses being rebuilt right now," Peterson said. "So we're seeing mission accomplished."
Peterson also said that this was the first time the Army Corps had done a wildfire debris removal job, and that it learned lessons along the way.
In the letter, Ghilarducci called on the Army Corps to re-engage with the state to fix some of the costly issues that remain for homeowners. He wrote the state has already spent millions of dollars on repair.
Peterson said the Corps wishes to resolve issues that are within its authority to fix.
"But understand," he added, "our missions and our resources to address those missions in a disaster come from FEMA."
The Stafford Act indemnifies the federal government from all claims arising from damage done during disaster debris removal projects.
FEMA did not immediately respond to KQED's request for comment.
The letter also said that the Army Corps failed to provide Cal OES with key documents that would have helped the state respond to hundreds of complaints from wildfire survivors.
Peterson said the cleanup project was completed in cooperation with Cal OES, and that communication was ongoing.
"I guarantee you they've got our phone number," he said.
The Governor’s Office of Emergency Services spokesman Brad Alexander said that his office did not wish to comment.
"The letter speaks for itself," Alexander said.
