Briefing Document: Community Discussion on Wildfire Preparedness
and Water Infrastructure
Subject: Analysis of Community Forum Regarding Recent
Southern California Wildfires and Implications
for Marin County
Sources: "Water needs
Next Door chat"
Overview:
This document analyzes an online community forum discussion sparked by the
recent devastating wildfires in Southern California, specifically Los Angeles.
The conversation revolves around the adequacy of water infrastructure and
emergency preparedness in the face of extreme fire events, with a focus on the
potential implications for Marin County.
Key concerns include insufficient water systems for large-scale fires, the
importance of proactive planning, and the need for community education and
individual responsibility.
The discussion is heavily influenced by the unfolding disaster in LA, and this
context is important in reading the various reactions.
Key Themes & Ideas:
Inadequacy of Urban Water Systems for Wildfires:
The initial post cites a Washington Post
article highlighting that Los Angeles' water system was "never designed to
combat wildfire". The article states: "There’s no urban water system
engineered and constructed to combat wildfire... The system was intended to
supply water to homes and businesses, he said, and to help fire crews defend
a large structure or several homes, not multiple neighborhoods at once."
This introduces the core issue that existing infrastructure is primarily for
regular water needs, not extreme firefighting demands.
The discussion emphasizes that
tanks are not designed to refill fast enough to meet the demands of a
large fire, leading to water shortages when needed the most. A commenter
remarks, "The
tanks were not able to refill fast enough to meet the overwhelming
demand from the enormous firefighting response."
The Importance of Planning and Infrastructure Investment:
Several participants stressed the need for proper
planning to prevent poor outcomes, with one user stating, "Proper planning
prevents poor performance." This highlights the urgency of addressing
vulnerabilities before a crisis occurs.
Marin County's Fire Flow Improvement Plan, funded by
a $75 annual parcel fee, is referenced. This plan aims to increase water
flow for fire fighting, replace inadequate pipes, and seismically stabilize
pump stations. One commenter wrote: "A first-ever master plan for making
fire-flow improvements in central and southern Marin was begun following
voter approval in 1996... In 2012 the Marin Water Board of Directors
approved extending the $75 annual fire flow fee...". The user noted,
"I will no longer complain about that 75$ fee which I never understood
as a new resident here." This suggests that residents were unaware of
the significance of this dedicated funding, but that is now being realized.
Concerns about Accountability and Transparency:
The discussion reveals a distrust of government
management of resources, with some questioning if past funding for
infrastructure improvements was properly used: "where’s the money gone
collected from tax payers? this state is so corrupt."
There are also questions about the timing of a
reservoir being out of service for repairs right before major fires and
whether this was an example of poor planning: “Critical reservoir left
empty. Unbelievable.” and "When they say that the reservoir was out
of service�� it’s been out of service and empty since February 2024�� that
is an example of incompetence!" These questions demonstrate a desire
for greater transparency regarding public infrastructure management.
The Role of Prevention and Mitigation:
The thread makes it clear that building bigger and
better infrastructure may not be the only answer. Participants emphasize the
need for prevention, highlighting measures such as defensible space,
controlled burns, underground utilities, and addressing climate change. As
one participant states, "The solution is prevention. Defensible space,
controlled burns, underground utilities, and undoing climate change."
Another user noted that climate change was not easy
to undo, "climate change in all likelihood cannot be undone. We need to
adapt as best we can."
Community Education and Individual Responsibility:
The importance of individual preparedness is also
discussed, with some noting the need for evacuation plans, emergency bags
and knowledge of the fire danger in their areas. One user commented, "If
and when an evacuation order is placed don't wait. Calmly grab bags for your
family. Also don't forget your pets and having food, meds packed and ready
to go."
The forum also includes a link to a Fire Safe Marin
video regarding Wildfire Evacuation Tips.
The Debate Over Causes and Responsibility:
While the discussion acknowledges extreme weather conditions and climate
change as major factors, some participants express skepticism about climate
change's role and focus more on government mismanagement and potential
corruption.
One participant said "Blaming climate change is
a way to do nothing."
Another noted: "Everyone is looking for a reason
and who to blame. Sometimes everyone does everything right. The planning is
good. And bad things still happen."
The politicization of the issue is evident, with
accusations of political bias by the media. One comment suggested, "They
are using this catastrophe to score political points." and "It is
impossible for even the best lead, planned and organized states to plan for
every scenario."
Alternate Firefighting Strategies:
There is a discussion on the effectiveness of water
use during large wildfires with an idea that a new strategy is needed that
will be more effective, with a focus on preventing spot fires. One
suggestion was to have "Station one or two Firefighters at each adjacent
and downwind home , armed, simply, with a garden hose! Putting out spot
fires from the flying embers, -- before it ignites the home."
Another user questioned if firefighters were doing
the right thing, stating, "Instead of pouring gallons of water, through
a large diameter hose, on a home that is already burning and unlikely to be
saved. And as a result prematurely emptying
Tanks that feed all hydrants."
The Importance of Alternative Water Sources:
The conversation explores alternative water supplies
for fighting fires. One participant shared a reference to the Auxiliary
Water Supply System (AWSS) in San Francisco that was built after the 1906
earthquake. One user noted, "We need an AWSS system - very sensible. And
it can run off salt water too." However, there is also the recognition
that Marin County is significantly larger than the city of San Francisco and
that such a system would require significant funding. "AWSS is a
wonderful system, but remember SF is only 7 square miles. Marin is a LOT
bigger than 7 square miles. If that is what you want, be prepared for much
higher taxes."
Generator Reliability:
There is some discussion on the need for back up generators for water
pumps and concerns about the reliability of the generators and their
maintenance. One user notes that "One of the problems with generators is
that they sit and decay unless you have a full time maintenance ,when you
really need it wont start."
Others defended the maintenance of generators at the government level
and discussed that this was a known issue, "as a person who was in
charge of maintaining generators for a city it’s your job if they don’t
start."
Specific Facts & Figures:
Marin Water Fire Flow Improvement Plan: A $77 million
capital project funded by a $75 annual parcel fee, extended through 2031,
for water system improvements.
San Francisco's AWSS: A 135-mile pipeline network, separate
from the regular water supply, designed for firefighting, including
saltwater capabilities.
Tank Capacities: Various capacities of
water tanks in Marin County are listed.
Quotes Highlighting Key Points:
"There’s no urban water system engineered and constructed to combat
wildfire." - Michael McNutt, spokesman for the Las Virgenes Municipal
Water District
"The tanks were not able to
refill fast enough to meet the overwhelming demand from the enormous
firefighting response." -
"Proper planning prevents poor performance." -
"We need an AWSS system - very
sensible. And it can run off salt water too" -
"AWSS is a wonderful system, but
remember SF is only 7 square miles. Marin is a LOT bigger than 7 square
miles. If that is what you want, be prepared for much higher taxes." -
"climate change in all likelihood cannot be undone. We need to adapt
as best we can." -
"The solution is prevention. Defensible space, controlled burns,
underground utilities, and undoing climate change." -
Conclusion:
The online discussion highlights the deep concerns about water
infrastructure, emergency preparedness, and response strategies in Marin
County in light of the devastation in Southern California. While the LA
experience has raised awareness, there is a lack of consensus on the
underlying causes of the problems. There is a shared sense that current
systems may be inadequate for extreme fire events. The conversation emphasizes
the critical need for proactive planning, community education, and a holistic
approach that includes prevention, mitigation, and adaptation. There is also a
desire for more transparency and accountability regarding water and
infrastructure management, with an emphasis on community responsibility. The
group seems split, with some believing that climate change is the main factor,
others believing that poor government planning and corruption are the reason
for the fires, while some see it as a perfect storm of the two factors.

FAQ: Wildfire Preparedness and Water Infrastructure
Why was the water system in Los Angeles unable to cope
with the recent wildfires?
The water infrastructure in Los Angeles, like many urban
areas, was primarily designed to supply water to homes and
businesses, and to assist with fire suppression for individual
structures or small areas, rather than to fight multiple
large-scale fires simultaneously. Storage tanks and pumping
systems were overwhelmed by the enormous firefighting demand, and
they simply couldn’t refill fast enough. Additionally, the use of
residential sprinklers in burning buildings exacerbated the
problem, draining water supplies further. A reservoir was also out
of service due to repairs and a torn cover that made it unsafe for
consumption. This confluence of events highlighted that existing
urban water systems are not engineered to combat widespread
wildfires, especially under extreme conditions like high winds.
What steps has Marin County taken to improve its water
infrastructure for firefighting, and how are these efforts funded?
Marin Water initiated a fire flow improvement plan in 1996,
prompted by voter approval, and funded by an annual $75 parcel
fee. This effort, initially slated for 15 years, was later
extended an additional 19 years (2012-2031). The collected funds
are being used to replace approximately 52 miles of inadequate
pipe and for seismic stabilization/retrofits at pump stations and
pipe bridges. This aims to increase water flow for firefighting
and ensure the integrity of the water transmission system.
What are some of the critical vulnerabilities in water
systems during wildfires as highlighted by this event?
Several critical vulnerabilities were exposed. First, the
inability of water storage tanks to refill quickly enough to keep
up with demand was a major issue. Secondly, power outages affected
pump houses, leaving tanks to run dry. Thirdly, residential
sprinkler systems in burning buildings continue to drain water
resources, compounding supply issues. Finally, the concurrent use
of hydrants and home services off the same pipes was a clear
problem. These challenges illustrate the need for more robust,
resilient systems that can withstand extreme events.
Beyond water infrastructure, what other strategies are
necessary to better prepare for wildfires?
Several strategies were discussed, including a focus on
prevention, which is viewed as critical since infrastructure can't
practically be built to handle every 'doomsday' scenario.
Defensible space creation around homes, controlled burns to reduce
fuel loads, and burying utilities are important. In the context of
large fires, strategies like using garden hoses at adjacent
properties to extinguish spot fires while professional
firefighters focus on active flame fronts, utilizing
fire-resistant suits, having readily available emergency supplies,
and ensuring community awareness of evacuation procedures are
critical. Also, residents should evaluate home insurance policies
and actively implement home protection strategies.
Why were some reservoirs inoperative during the Los
Angeles wildfires, and how does that impact firefighting?
The Pacific Palisades reservoir was out of service for repairs
after its covering was damaged making it unsuitable for drinking
water. The timing of the repairs (during fire season) became a
major problem when a massive fire broke out, resulting in the
reservoir being unavailable. This illustrates the challenges of
balancing infrastructure maintenance with the need for readiness,
particularly in high-risk areas. While necessary for public
health, the timing of the repair left the community vulnerable.
There are differing opinions on whether the timing was "poor
planning" or just poor luck.
How does the concept of a "dedicated firefighting water
system," like San Francisco's Auxiliary Water Supply System (AWSS),
apply to other communities?
San Francisco's AWSS is a high-pressure system, separate from
the city's regular water supply, with a dedicated network of
pipelines, reservoirs, tanks, pumping stations, and fire boats. It
even can pump salt water from the bay. This system was designed
specifically for firefighting after the 1906 earthquake and fire.
However, replicating it in larger areas like Marin County would
likely be significantly more costly and logistically challenging.
While the idea of a dedicated system is appealing, it is very
expensive and may be a difficult to implement in a larger
geographical area.
What role does climate change and high winds play in
exacerbating wildfires, and what can be done?
Climate change contributes to prolonged droughts and hotter
temperatures, creating more dry vegetation to act as fuel for
wildfires. Extreme wind events, like the Santa Ana winds, also
significantly intensify the severity and spread of wildfires,
making them virtually unstoppable in their initial stages. While
it's recognized that climate change cannot simply be "undone,"
adaptation is crucial, and must involve proactive measures such as
defensible space, controlled burns, and infrastructure
improvements. The impact of high winds, which propel embers great
distances, can rapidly overwhelm even the best prepared
communities. Some say "blaming climate change is a way to do
nothing" though the majority of climate scientists agree human
activity is the primary cause.
Besides infrastructure upgrades, what changes to fire
response and evacuation strategies might be needed to better address
wildfires?
Several changes could be beneficial such as:
More localized response: Firefighters
focusing on protecting homes adjacent to fires, armed with
smaller garden hoses to extinguish spot fires instead of pouring
water on already burning structures.
Pre-emptive measures: Distributing
fireproof suits to fit and prepared homeowners who are willing
to help protect homes during a fire.
Strategic water use: Recognizing the
limitations of current systems, with the need to conserve water
in extreme events. This may involve deploying mobile water
tanker trucks to areas most at risk.
Improved community preparedness:
Emphasizing evacuation planning, with a clear understanding of
safe zones, and the best method of transportation.
More strategic evacuation planning: A
recognition that some evacuation plans might not be feasible,
such as encouraging evacuation by bicycle, scooter or foot.

Answer Key
stated that LA's water system was intended to supply water to
homes and businesses, as well as aid in defending individual
structures or a few homes. The system was not designed for a
large-scale wildfire event, which overwhelmed its capacity to
provide adequate water for multiple neighborhoods at once.
The $75 annual fire flow fee in Marin was created to raise funds
for water system improvements that would increase water flow for
fighting fires and ensure the integrity of water transmission. It
was initially approved for 15 years, and later extended for an
additional 19 years to fund necessary upgrades.
Beyond infrastructure, suggested solutions such as
prevention, including creating defensible space, implementing
controlled burns, developing underground utilities, and addressing
climate change as ways to mitigate future fire risk.
A key system failure was the fact that the Santa Ynez Reservoir
in the Pacific Palisades was out of service for repairs. This meant
a significant water source was unavailable when it was needed for
fighting fires in the region.
After the 1906 earthquake and fire, San Francisco created the
Auxiliary Water Supply System (AWSS), a high-pressure system
separate from the regular water supply, including a pipeline
network, reservoirs, tanks, pumping stations, fire boats, and
cisterns. The system can use both freshwater and saltwater for
firefighting.
The discussion suggests that high winds significantly intensify
wildfires. Strong winds spread flames and embers rapidly, making it
harder for firefighters to control the fire and increasing the
likelihood of homes catching fire. It is suggested that above 45mph,
firefighters will no longer try to extinguish the fire.
The Pacific Palisades reservoir was out of service for repairs
because a covering designed to preserve water quality had torn and
was contaminating the drinking water. While this was necessary, it
coincided with an extreme fire event, leaving the area without a key
water supply.
Some people argue that residential sprinkler systems, especially
when homes are burned, drain the water supply further. It is also
argued that some systems should shut off when the building burns
down. Others believe they can provide some protection.
believes that the focus should be on supporting the victims of
the fire and that it is not productive to dissect every aspect of
the tragedy. ., on the other hand, wants accountability for what
went wrong and to explore what could have been done better to
prepare for this event.
Lisa S. believes that assigning blame and politics has been
dominating the discussion of the fires instead of concentrating on
support, recovery, and an unemotional analysis of lessons learned
once things have calmed down.
