Officials are urging residents throughout the San Diego region’s most fire-prone areas to prepare for this year’s peak wildfire season. The county is slated to mail out its “personal disaster plan” to roughly 200,000 homes and businesses starting next week. The recently updated 16-page document will be sent to those living in areas designated by the California Department of Forestry and Fire Protection as “very-high fire severity zones.” The plans — which will be provided in both English and Spanish — will also be available starting in November up at any one of San Diego County Library’s 33 branches. The document can also be downloaded at readysandiego.org. “This is the most dangerous time of the year. This is when some of our biggest wildfires have happened,” Supervisor Dianne Jacob said in a news release.
