A nice heavy rainy day in B'game is the perfect time to reflect on Not Forgetting about our wildfire risk. Almost three years ago we covered the Emerald Hills fire here. Then came Pacific Palisades and Altadena which has pushed FAIR into the red and will cost all of us a pretty penny in insurance increases. It's one thing to write State Farm or Farmer's a bigger check, it's quite another to lose your home.
The risks are multi-dimensional. How good is our fuel management, particularly up the hill with our neighbors? The state is updating the high-risk maps as part of Newsom's latest revelation that the 5 foot "Zone 0" area next to dwellings needs to be clear of fuel. One has to wonder where he's been for the last five or ten years? You can get a sense of the Hillsborough high-risk area here. Swapping email with the CCFD Chief, I learned
In Hillsborough, the town conducts fuel management on town owned parcels and we have an extensive Wildland Urban Interface inspection program. Inspections are conducted annually and education and enforcement is applied according to the situation.
I know from friends that there have been non-renewals and big increases in insurance rates up there. The insurers have reportedly also used drones to find private parcels that are at high-risk from lack of fuel maintenance and some of that information may even be informing their rates for the neighbors. "It takes a village".
Our water supply is another aspect of preparation. Swapping email with Public Works, I learned
We tap SFPUC system near Magnolia/Trousdale and use its static head to a point near BIS on Trousdale, and from there it is pumped to the Mills Reservoir. From there, it gets gravity fed to Sky View Reservoir, which then serves the hillside area below. On the south side of the City, we pump the water to the Hillside Reservoir located next to the Fire Station 35, which then serves the water to the zone that is above and outside of the SFPUC aqueduct zone. We have four other SFPUC turnouts that we tap into to serve the remaining parts of the City primarily by gravity. Hillsborough has a separate system outside of Burlingame, much of their water supply is pumped to their hills and then served to the residents unlike Burlingame.
A bit more research is in order for the layperson to follow the plumbing described above. It's also a fair question to wonder how up to date the various parts are right now. I asked about how we go about flushing the hydrants? It was a pretty common thing to see when I was a kid, but I can't recall seeing it in B'game. I've must have missed it since Public Works states
Burlingame has proactively invested in a robust capital improvement program to modernize its aging water infrastructure over the past few decades. This includes replacing several miles of water mains and upgrading older fire hydrants with newer models and adding new fire hydrants if needed. These efforts have not only enhanced the City’s water capacity but have also significantly improved fire protection. The hydrant flushing program is active and we rotate the program throughout the City based on water quality parameters. The public may see more at some times than others as needed based on our water quality requirements.
The bottom line is B'game is not one of the eight cities in San Mateo County at the highest risk as shown here. We have a lot of infrastructure. We have maintenance plans. My discussions with a concerned H'borough resident lead me to continue to believe our biggest risk stems from big private parcels up there that may not be on top of fuel management. With all of the eucs up there, the effort described in the Merc about the work at East Bay Parks is something to aspire to here.
East Bay Parks has nearly quadrupled its fuel reduction staff in the past five years to take on the Herculean task of bringing the forest back into order, including the addition of Fuels Reduction Coordinator Givonne Law.
“Eucalyptus is notorious for being a very difficult-to-handle tree. Not only is it very heavy, but there’s generally huge accumulations,” Law said. “A lot of machinery operators out there will see a project like this and will just walk away.”
Law’s task was to thin the forest from more than 750 eucalyptus stems per acre to 150 stems per acre. Her aim, she said, was not to eliminate eucalyptus — despite their oily, flammable properties — but to reconstitute the balance of the forest to allow less dangerous trees such as bay and oak to reestablish themselves.
That works out to about one stem per 300 square feet–a 17 x 17 foot area. A drive through H'borough will easily show areas with more density than that.
