TU16 - Lessons Learned from the Detwiler Fire, Mariposa County, California

Aug 28, 2018 2:00pm ‐ Aug 28, 2018 2:50pm


Mariposa County, California, was still recovering from storm damages to bridges and roads that occurred in February 2017, when the Detwiler Fire occurred in July. The fire lasted 22 days, consumed just under 82,000 acres and 68 homes, and damaged or destroyed another 138 structures. Over 90% of county residents were evacuated for up to 16 days. County Public Works and Transportation Department staff will describe what they learned about emergency operations center activities, recovery operations, and re-population needs. In short, when is recovery over? For many, never.

Learning Objectives: At the conclusion of this session, you will be better able to:

  • Review your own operations and ask if your team really knows all that it needs to know to be ready when a disaster hits.
  • Determine if your community is prepared for post-disaster consequences; not only the impacts on infrastructure, put the impacts on economic health and the needs of a suffering population.
  • Think on your feet and find creative solutions to emergency situations.
