Winter Storm Damage Survey

As we recover from the recent severe storms that caused damage across the Bay Area, the Contra Costa County Office of Emergency Services is trying to expand the available assistance, but we need your help. 

In order to qualify for Federal Disaster assistance for private residents, the County must demonstrate exceptional private property and business losses due to the recent severe Winter storms. If you experienced damage to your property or business, you are invited to fill out the brief County Winter Storm Damage Survey by clicking here.

The survey results will help us qualify for State and Federal disaster funds for individual residents. This survey is not an application for assistance but is the first step in the disaster recovery process.
