A lot of abbreviations this week. Cal Fire release their fire map of three levels of FHSZ (Fire Hazard Severity Zone). ROE must be turned in by March 30, 2025 for either opt-in or opt-out or the City will clean your site up starting on July 1st on your dime. The recommendation is that opt-in before March 30th, you can always opt-out later. FEMA & SBA assistance deadline extended to March 31, 2025. And Mayor Bass issued another Executive Order EO#5 on March 21st. Lastly, AIA CA hosted an very informative meeting on home hardening techniques that I’ll share once it’s online.
What does the FHSZ zones mean?
According to Cal Fire, these maps are required by law. They are mapping hazard, NOT risk. It identify levels of fire hazard. There are 3 levels: Moderate, High, & Very High, hence the VHFHSZ designation for the Palisades and Altadena. Essentially, all of the the hillsides are designated as VHFHSZ. Palisades has been designated as VHFHSZ for a while now. HERE is a link to how these zones are set up. Most of the new constructions were also built to the VHFHSZ standards, which means interior fire sprinklers, class-A roofing, 1 hour exterior walls, and dual glazed windows with tempered glass. What is new is that new structures will be required to create an ember-resistant zone within the first five feet around habitable structure in the SRA (State Responsibility Areas) and VHFHSZ (Very High Fire Hazard Severity Zone) LRAs (Local Responsibility Areas) upon the Board of Forestry and Fire Protection approval of AB 3074. This means no vegetation within the first five feet of the structure. This will probably take effect for all of the new structures that are being submitted and take effect for existing structure in three years. Currently, Pacific Palisades is in the LRA area. The local fire department may also be considering other regulations to be incorporated, so please check with the fire department when you submit your drawings.
HERE is the map where you can find your FHSZ zone. HERE is a link to the FAQ about the zones and HERE is the link for the LRA rollouts. If you are really interested, HERE is the link to the proposed rule packages for the LRA.

What does this all mean for insurance? This is part of the Mayor’s EO#5, there is supposed to be a report within 60 days to explore expanded insurance options and provide guidance to homeowners on insurance availability and pricing for wildfire-resilient homes.
EO#5
This EO focuses on the rebuilding and home hardening. I’ve already published the link to the EO on March 19th, if you look back on the blog. The main points are that the city departments will develop paths forward to:
Streamline permitting for owners who rebuild all-electric, more fire-resistant homes. Please note, this is on top of rebuilding like-for like.
Promote the use of fire-resistant construction materials.
Further strengthen the resilience of utilities.

Home Hardening Techniques
Creating a continuous layer that envelope the home best protects the home. Most home burned in a wildfire scenario are from embers, not the vegetation itself. With that said, it’s still important to create a fire resistant perimeter around the structure. AIA CA hosted a very informative webinar on both how to harden the home in new construction and retrofit with Q&A afterwards. Cal Poly San Luis Obispo has a WUI (Wildland Urban Interface) Fire Institute that studies this. The director Frank L. Frievalt had a great point that none of this works unless we have the local government buy-in on all aspects. Meanwhile, here are few takeaways from the seminar.

Final Thought
As we rebuild, let’s not forget about the older survivors. Those older residents that have lived in the Palisades for decades, who thought they were spending their golden years living in a paid off home and enjoying the fruits of their decades of labor, have just lost everything. Try and reach out and give them support. “We Lost Everything”: Older Wildfire Survivors Face an Uncertain Future — Department of Angels
