Why bigger, more destructive wildfires? Oct 2020

Climate in California has changed over the last century and during the last four decades. The changed climate is a fire threat multiplier.

Temperatures have risen especially in summer and autumn such that a new hotter climate regime concentrates precipitation in December and January with decreased amounts in autumn and spring.

Increased drought and drying of fuels have stretched the length of the peak fire season months of September through November (SON) into December and increased the territory burned exponentially.

The autumn and winter in California frequently have dry, strong, downslope, off-shore winds, called Diablo winds in Northern California and Santa Ana winds in Southern California. They can vastly increase the danger by boosting the speed of fire propagation.

Such was the case of two episodes in November, 2018 that Michael Goss, et al. discuss in detail, the oak woodland Camp Fire that wiped out the small city of Paradise in the northern Sierra Nevada foothills that killed 58 people, and the coastal chaparral Woolsey Fire that jumped the 12-lane 10l freeway early in the morning of its second day and rushed six miles over mountains to the sea near Malibu by noon. The Woolsey Fire started with humidity at only five percent and wind gusts of 40-50 mph.

=====================================

In November 2017 a group of neighbors started working to create the first Firewise group in Santa Cruz.

With the help of Fire Chief Jason Hajduk, one active group formed on the East Side of Santa Cruz, and two new ones are forming on the West Side. We have been meeting with our neighbors regularly to learn about wildfire preparedness and have conducted public meetings, yard cleanup events, and home risk assessments.

Recent Events:

May 4, 2019 was national Wildfire Community Preparedness Day. To join in the effort, Santa Cruz Firewise conducted projects in several Santa Cruz neighborhoods to reduce wildfire risk, including yard clean-ups, gutter clearing, creating defensible space around homes, and spreading of wood chips as mulch.

In support of this day, Mayor Martine Watkins issued a proclamationMay 4 Mayor's Proclamation.jpeg

declaring May 4, 2019 Wildfire Community Preparedness day to “encourage all residents to recognize the importance of wildfire prevention efforts and work together to enhance our resilience and readiness.” We thank the Mayor for the proclamation and the City’s support.

April 1, 2019: Fire Battalion Chief Robert Young and Urban Forester Leslie Keedy conducted a demonstration walkthrough around two Prospect Heights homes to assess fire risk and teach us how to create defensible space around our homes. See Defensible Space for details and advice for everyone on how to do this

Things you can do to protect your home: The FireWise homepage has detailed information on what areas and actions you should focus on around your home to reduce wildfire risk and losses.   For additional information on projects you and your neighbors can easily accomplish visit www.wildfireprepday.org

The National Fire Protection Association’s “Firewise USA®” program (nfpa.org) teaches communities how adapt to living with wildfire by encouraging neighbors to work together and take action to protect their homes. It provides information and resources to help neighborhoods understand wildfire risk and engage in risk reduction efforts.
