Stormwater runoff has emerged as a primary water quality issue.
In urban areas, after long dry periods rainwater runoff can
contain accumulations of pollutants. Stormwater does not go into
the sewer. Instead, pollutants can be flushed into waterways with
detrimental effects on the environment and water quality.
In response, water quality regulators use a range of programs to
reduce stormwater pollution including limiting the amount of
excess runoff and in some cases recapturing freshwater as well.
The California Department of Toxic Substances Control (DTSC)
put tire manufacturers on notice that California wants them to
explore alternatives to using zinc, a toxic chemical that harms
aquatic life and burdens waterways. Zinc helps make rubber
stronger, but also wears off tire tread and washes into storm
drains, streams, rivers and lakes, threatening California fish
and other aquatic organisms.
In 2016 the City of San Jose became the first Bay Area
municipality to get credit for homeless encampment cleanups
under its stormwater permit. So far, the city has exceeded
the permit’s annual requirements, most recently removing 446
tons of rubbish—more than double its goal—from encampments
along waterways. But Covid-19 has complicated this effort.
The Port of San Diego has approved a pilot project to develop a
portable five-in-one field-testing sensor device to provide
real-time metals analysis for stormwater monitoring. The

Scientists in the Pacific Northwest say they’ve solved a
long-running mystery behind the region’s dying salmon, a
discovery that may explain what’s harming fish elsewhere around
the globe, including California.
By burning and brushing, nurturing important plants and
keeping lands around their homes clear of dead brush and
debris, Native peoples carefully stewarded the lands to sustain
the biodiverse ecologies California is known for. Their
work resulted in a richly productive landscape that provided
food and habitat for not only humans but many land, air and
water animals. That included the salmon, a staple of tribes in
the West for millennia. All that changed when California became
a U.S. state in 1850.
The North Yuba Forest Partnership has entered into an agreement
to receive $1.13 million to plan future forest health and
wildfire resilience treatments within the North Yuba River

Communities across the United States and the globe rely on
clean water flowing from forested watersheds. But these water
source areas are impacted by the effects of wildfire. To help
water providers and land managers prepare for impacts from
wildfire on water supplies, the U.S. Geological Survey is
working to measure and predict post-fire water quality and
Just weeks after the Bobcat fire ravaged the San Gabriel
Mountains, state and federal biologists are racing to salvage
as many federally endangered species as possible before storms
could inundate the animals’ last outposts with mud and debris.
… “This may be the last time in my life that I see wild
mountain yellow-legged frogs in the last best place for them,”

Wildlife in the upper Putah Creek watershed was devastated by
the LNU Complex Fire, which started on Aug. 17, was finally
extinguished on Oct. 2, and grew to be the fourth largest in
California history. However, the oak woodlands in this region
have evolved with fire, and with natural resiliency and a
little support from local agencies, recovery is expected.
With California’s worst wildfire season on record still raging,
experts from across the state are calling for a $2 billion
investment in the next year on prevention tactics like
prescribed burns and more year-round forest management
The [Butte] county’s Forest Health Watershed Coordinator Wolfy
Rougle said there is indeed reason to worry about preventing
toxic runoff quickly, particularly with the magnitude of the
North Complex fires’ destruction, and the county’s resources
are stretched thin…So small nonprofit organizations typically
have boots on the ground to do the work with concerned
residents, like the Camp Fire Restoration Project.
All of Santa Barbara’s beaches and creeks are designated as
“impaired” under the federal Clean Water Act. … The council
voted 7-0 to send its proposed changes to stormwater runoff to
the Central Coast Regional Water Quality Control Board… The
list of changes are extensive, and are proposed over four tiers
based on various types and levels of new construction
development. They involve landscape changes and stormwater
treatment for new impervious construction.
Results from the model showed potential increases in large flow
events and sediment transport over the next century. While

The last time Mt. Tamalpais had a major wildfire was in 1929.
In 1930, Marin’s population was 41,648. Today it’s more than
258,000. … As with many other utilities, the Marin Municipal
Water District is updating its treatment plants. It is unclear,
from a technology and science perspective, whether our
community treatment plant could handle sediment runoff from a
big rainstorm after a catastrophic, climate-driven wildfire.
When fires burn up vegetation, the charred remains become
hydrophobic—meaning they repel away any water. The soil is also
very dry, which counterintuitively makes it harder for water to
infiltrate. … Fires can also destroy the natural clumps in
soil, increasing their erodibility. Altogether, this means that
water is hitting the ground with more force and the soil is
unable to suck it up.
For years, a stretch of Chorro Creek near Hollister Peak ran
through active farmland, where its flow was diverted for
irrigation and its banks were shored up by levees, blocking the
water’s natural access to its floodplain. … After nearly two

The main stormwater issue associated with solar arrays is the
concentrated discharge of stormwater runoff at the solar panel
drip line, which can act like un-guttered roofs that channelize
and accelerate stormwater flow. Instead of traveling as sheet
flow across a fallow field, capped landfill, or macadamized
parking area, stormwater now lands on the surface in
channelized sheets that must be carefully managed to prevent
soil scouring, erosion, and contamination…
Scientists at Salo Sciences, a startup that works on technology

EPA Administrator Andrew Wheeler said Wednesday the agency
would pay for more water treatment south of the border, and
work with San Diego to control trash coming into the United
States from Mexico by way of the Tijuana River. Wheeler made
the announcement during a visit to Southern California, a
region long plagued by sewage, water, trash, and other
contaminants flowing from Mexico.
In burning to the edge of Lake Sonoma, the Walbridge fire has
posed an unprecedented threat to the water supply for 600,000
North Bay residents and scorched Sonoma County streams critical

report from the California State Legislative Analyst’s office.
After timber harvest or fuel reduction thinning operations,
sediment delivery to nearby streams and waterways can increase,
potentially affecting water quality, drinking water supplies,
habitat, and recreational opportunities. To effectively reduce
these adverse effects of harvest, foresters first need to know
the precise causes of sediment increases.
As part of Valley Water’s mission to provide flood protection
for our communities, we are continuously preparing for the

Both United States and Mexican officials announced separate
plans Tuesday to upgrade Tijuana River wastewater facilities.
The international river has been a longtime problem for
residents of Imperial Beach and Tijuana, as sewage and trash
from the river have spilled into the Pacific Ocean for decades,
often closing beaches near the border and damaging natural
habitats along the river.
Hundreds of studies on nature-based solutions to extreme events
show that “green infrastructure” is often cheaper and more
effective than engineered projects like dams, levees and sea
walls, according to a new analysis. Experts say federal and
state governments should heed those findings and increase
funding for natural landscapes and systems to reduce climate
disaster risk. Solutions include floodplain restoration and
“living shorelines” along vulnerable coasts and rivers.
In May, Cyclone Amphan made landfall in Bangladesh and eastern
India. The category 5 storm forced around 3 million people to
flee their homes. With this scenario in mind, a group of

emergency managers so that they can prepare before the storms
The U.S. Environmental Protection Agency (EPA) announced a $196
million Water Infrastructure Finance and Innovation Act (WIFIA)
loan to the Inland Empire Utilities Agency in San Bernardino
County, California. The loan will help finance expanded
wastewater treatment capacity to support public health and the
environment in this growing community.
The term “crisis on the border” typically refers to immigration
issues or drugs being smuggled into the country. But it has one
more meaning, as we discovered, when we went to the border in
early February: tens of millions of gallons of raw sewage that
spill every year into the Tijuana River on the Mexican side and
flow across the border right into Southern California,
polluting the land, air, and sea.
Outbreaks of E. coli illness that sickened 188 people who ate
romaine lettuce grown in California probably came from cattle
grazing near the farms, the U.S. Food and Drug Administration

Although it is clear that river discharge is the major source
of plastic pollution entering the oceans, there remains
uncertainty around how plastic pollution is transported through
rivers and coastal marine waters. How important is stormflow
for delivering plastic pollution from rivers to the coastal
ocean? How are microplastics transported through coastal
environments? How much is eventually sinking and settling on
Stormwater is the rain and other water that runs off of streets
and sidewalks into nearby gutters or waterways. Communities
throughout the western U.S. are expanding efforts to collect
this valuable water resource. These projects range from
capturing water from a single rooftop or driveway to developing
large infiltration basins that recharge billions of gallons of
water each year in groundwater basins.
In a time when many people in the world are inside their houses
to stop the spread of covid-19, it is easy to forget that good

Nobody seems to know why a rope that caused a nearly weeklong
boil-water advisory in Poway was there in the first place. The
rope had been hanging on a wall in a vault adjacent to the
clearwell drinking water reservoir and a stormwater drain. When

yesterday may not be adequate for the new wildfire reality of
The Groundwater Resources Association’s 2019 Western
Groundwater Congress featured David Sandino, Senior Staff
Counsel at the Department of Water Resources, who spoke about
the disconnect between legal groundwater systems and how the
system actually works; and Maurice Hall, Associate Vice
President of Ecosystems-Water at the Environmental Defense
Fund, who spoke of how more holistic and inclusive groundwater
management can increase the resilience of our water supply…
The Metropolitan Water District of Southern California is
expanding its effort to learn more about the water supply
potential of local stormwater capture with a new $7.5 million
pilot programapproved today by its board of directors.
San Marcos will start construction of its Creek District this
year, with a $100 million plan to reduce flooding and improve
habitat and traffic flow, officials said at a public forum
earlier this week.
In order to take care of environmental concerns and maintain
our facilities in a safe and effective manner, we have
identified about 900 encroachments on public lands managed by
Valley Water that require resolution. … Valley Water has
implemented a new process to resolve these encroachments by
working with our community.
Santa Fe Dam is an element of the Los Angeles County Drainage
Area (LACDA) flood control system. Watersheds are more than
just drainage areas in and around our communities. They are
necessary to support habitat for plants and animals, and they
provide drinking water for people and wildlife.
The Trump Administration’s EPA takeover, with its race to the
bottom rollbacks of the environmental and public health
protections that Americans have relied upon for decades, is
low; so low that even some of the industries the Administration
seeks to support are pushing back. But what the Trump
Administration has been up to lately in California–
weaponizing the Clean Water Act to serve a political
vendetta…well, can it get any lower than that?
Alameda property owners are being asked whether they are
willing to pay more to maintain and upgrade the city’s aging
stormwater system. … The reason? The city’s stormwater fund
is running a $1 million annual deficit and the system needs
about $30 million in upgrades, including at its pipe stations,
some of which date to the 1940s…
Elizabeth Castillo looks on as her daughter Reynata plays with
children at a playground near the Los Angeles River in Long
Beach, California, in mid-October, hoping one day the river
will be clean enough to kayak on. … In the last half-century,
the LA River served primarily as flood control infrastructure,
but open space and wildlife advocates fomented a movement to
make it wild and accessible to all.
When nitrogen-based fertiliser runs into water systems it can
result in toxic algae blooms, leading to oxygen depletion and
vast oceanic ‘dead zones’. Evidence suggests their use also
contributes to air pollution, increased rates of cancer and
reduced biodiversity, as well as emitting nitrous oxide – an
extremely potent greenhouse gas. … A team of scientists, led
by the University of California, Davis, has come up with a
five-step plan to tackle this two-sided problem.
The project includes improvements along more than 3 miles of
dirt roads, repairing culverts and building erosion control
features designed to reduce sediment flow into the creek. The
aim is to protect gravel nests, called redds, where female
salmon and steelhead lay their eggs, suffocating the eggs as
well as clogging the gills of adult fish…
When the Environmental Protection Agency administrator, Andrew
Wheeler, accused California of allowing “piles of human feces”
on city streets to contaminate sewer systems … the
accusations, contained in a Sept. 26 oversight letter, had been
developed without the knowledge of the California-based staff,
which would normally issue such notices. Instead, it was put
together by a small group of political appointees in Washington
assigned specifically to target California, according to three
current E.P.A. officials.
In case you’ve noticed some of the storm drains in the City of
Pasadena covered, the Department of Public Works wants you to
know it’s just following the rules. The covers are “catch
basins” and they are used for gathering trash samples
throughout the City to help in complying with mandated Total
Maximum Daily Load limits.
Nearly 600 former Environmental Protection Agency officials are
calling on Congress to investigate the Trump administration’s
“inappropriate threat of use of EPA authority” against the
state of California over recent environmental policies.
Drainage in Southern California was built around getting storm
water to the ocean quickly, but we now know that slowing down
these flows and encouraging water to soak into the groundwater
basin is preferable.
The Senate approved almost $20 million in funding to address
sewage flows along the border. Sen. Dianne Feinstein, who
secured language in three different appropriations bills for
the 2020 fiscal year, called the spills that send millions of
gallons of raw sewage from Tijuana to San Diego,
The ambitious tree-planting project falls under the purview of
Rachel Malarich, the city’s forest officer—a job that was just
created in August to “oversee the growth of Los Angeles’ urban
forest” as part of Garcetti’s Green New Deal. … The project
will grow what’s already the largest urban forest in the
country, making what happens in Los Angeles an important model
for other cities looking to go green.
California’s senators have asked the Environmental Protection
Agency’s watchdog to investigate whether the agency abused its
enforcement powers when it accused San Francisco of improperly
dumping waste into the ocean.
The U.S. Environmental Protection Agency issued a notice of
violation to San Francisco on Wednesday, accusing the city of
improperly discharging waste into the ocean and bay and
following through on President Trump’s recent pledge to cite
San Francisco for water pollution.
A new “green infrastructure” project under construction along
the western side of the block is designed to slow down that
process by detoxing the water through soil and plants and
pumping a purified product back out to the creek. The project,
a whopping seven years in the making, is part of a $4 million,
A new white paper released today by the Southern California
Water Coalition aims to further the discussion through its
provision of nine case studies of successful stormwater capture
projects from California to New York.
The California Water Boards sent at least 270 letters to
farmers in the Emerald Triangle, warning them to come into
compliance with regulations or face possible fines and even the
loss of their cultivation licenses.
This is supposed to be a beautiful beach, but instead it looks
like a disaster area because a sea wall built about a decade
ago to protect homes has failed. Now property owners are
spending millions to fix it.
Claims by President Donald Trump on Wednesday that discarded
drug needles in San Francisco are making their way through the
city’s sewage system and into San Francisco Bay and the Pacific
Ocean were widely blasted the following day by experts who say
he has no idea what he’s talking about.
“There’s tremendous pollution being put into the ocean because
they’re going through what’s called the storm sewer that’s for
rainwater,” Trump said. “And we have tremendous things that we
don’t have to discuss pouring into the ocean. You know there
are needles, there are other things.”
The Metropolitan Water District of Southern California on
Tuesday, Sept. 10, approved $5 million for a stormwater pilot
project to determine the best and most efficient way to capture
the tens of billions of gallons of rainwater that flow off
roofs and pavement each year.
The blue ocean has turned a rusty red in Manhattan Beach — but
what is causing this change in color? The red tide, as it’s
called, is from an algal bloom, according to Valerie Hill,
administrative and development director at the Roundhouse
Aquarium off the Manhattan Beach Pier.
Passed by voters in November 2018, Measure W—the Safe, Clean
Water Program—imposed a 2.5 cent/sq. ft. parcel tax on
impermeable surface construction in LA County and is set to
provide upwards of $300 million annually to support stormwater
and clean water infrastructure projects. TPR spoke with Katy
Young Yaroslavsky, on the Board of Supervisors’ recent approval
of the Measure W Implementation Ordinance…
A high-profile series of dog deaths has awakened the public to
the growing problem of toxic algal blooms, spurred by rising
temperatures and pollution. The blooms are emerging as a
national, not just regional, concern, according to preliminary
data reported to the U.S. Environmental Protection Agency
The only bi-national financial institution dedicated to funding
environmental infrastructure projects along the border unveiled
six possible solutions to slowing down the cross-border sewage
spills that routinely shut down southern San Diego’s beaches.
Los Angeles County residents will see a new charge on their
property tax bills this fall. Measure W, which was approved by
county residents last November, will implement a parcel tax
that is intended to increase stormwater capture. The intent is
to increase local water supply, improve water quality and
invest in community projects.
Oxnard Assistant Public Works Director Tien Ng presented the
item and said the city wants to integrate the water, wastewater
recycled water and stormwater while looking for opportunities
to align projects on the same street. They want to do them at
the same time. Doing this enhances the schedule and cost for
A major barrier to using urban stormwater is that it’s dirty.
Rain starts picking up contaminants the moment it hits
rooftops, streets, and other hard surfaces, as well as
landscapes laden with fertilizer and herbicides. … New
research shows that a cost-effective, low-tech approach can go
a long way toward cleaning up urban stormwater.
After a years-long drought and a major wildfire, rainstorms
brought a lot of ash and debris downstream over the past year
or so. … Now, Casitas officials hope to clear a
9-foot-high pile of silt, sand and gravel before the next
rainy season. Plans call for starting work in September, but as
of this week, the district had yet to receive permits required
by regional, state and federal agencies.
Rhys Vineyards LLC, based on the California Central Coast but
with vines in Mendocino County’s prime pinot noir region of
Anderson Valley, has agreed to pay $3.76 million to settle
enforcement actions brought by state wildlife and water
regulators for unpermitted diversion of rainwater runoff on
property of a planned small vineyard in a northern part of the
The California Coastal Commission has encouraged cities to
include a strategy called “managed retreat” in plans to prepare
for sea level rise. But the commission may be retreating from
that position. Del Mar is a prime example of a city where an
entire neighborhood is threatened by rising seas.
Native seaweed has the potential to be cultivated in California
coastal waters and used to alleviate the effects of local ocean
acidification, according to a new study funded by NOAA’s
California Sea Grant.
California’s biggest river—the Sacramento—needs a lot of room
to spread in big water years. A floodplain project called the
Yolo Bypass allows it to flood naturally, while also providing
habitat for waterbirds, fish, and other aquatic species. We
talked to Ted Sommer, lead scientist for the Department of
Water Resources (DWR), about this versatile landscape.
State water officials ordered an investigation this week into
the elusive source of contamination in Richardson Bay, where
water samples collected near Tiburon beaches have shown high
bacteria levels for more than two months.
Blasted by sun and beaten by waves,
plastic bottles and bags shed fibers and tiny flecks of
microplastic debris that litter the San Francisco Bay where they
can choke the marine life that inadvertently consumes it.
Fifty feet below the platform of the Powell Street BART Station
sits the starting point for one of the largest water recycling
projects in San Francisco — one that’s transforming dirty
groundwater into clean steam heat for hundreds of downtown
buildings. In the process, it’s saving tens of millions of
gallons of drinking water annually.
Today, Rep. Juan Vargas (CA-51) along with Reps. Susan Davis

People who fish for carp have a love for them, as I learned
when I joined my guides at the middle of the river in Long
Beach. Lauren Mollica, a former pro skateboarder who now works
primarily as a carpenter, has been fishing the L.A. River for
about a year, and she waxes rhapsodic about the scent freshly
caught carp leaves on one’s hands.
There’s a new twist in the California-Trump brawl in the state
Legislature. It’s aimed at overriding the president’s power to
weaken environmental protections. Put simply, any federal
protections President Trump tried to gut would immediately
become state regulations in their original, strong form.
Oscar Meinzer (1942) credits Leonardo da Vinci (1452-1519) with
having advocated the infiltration theory slightly before
Palissy’s time, basing his theories on observations made when
he was in charge of canals in the Milan area. … Such a
scenario might explain why California DWR staff and like-minded
academics and nonprofits have all jumped on the bandwagon of
managed aquifer recharge.
To find out what’s in Southern California’s oceans, Spectrum
News 1 went below the streets of Los Angeles into a storm drain
to track the flow of water. We’re diving into a question
scientists are facing: what is in L.A.’s water?
The experiment to super-energize water recharging efforts at
Fresno’s Leaky Acres appears to be working. … Tommy Esqueda,
then the director of Public Utilities, described the system to

Sixty percent of California’s developed water supply originates high in the Sierra Nevada mountains. Our water supply is largely dependent on the health of our Sierra forests, which are suffering from ecosystem degradation, drought, wildfires and widespread tree mortality.
Participants joined us as we guided them on a virtual journey into the foothills and the mountains to examine water issues that happen upstream but have dramatic impacts downstream and throughout the state.
Plans to capture stormwater runoff by installing rubber dams at
San Juan Creek will move forward… SMWD is working with the
city of San Juan Capistrano and South Coast Water District for
the first phase of the project, which, when completed, is
expected to provide 5.6 billion gallons of reliable drinking
water each year.
The polling firm FM3 Research found that a plurality of

Dan Efseaff, the parks and recreation director for the
devastated town of Paradise, Calif., looks out over Little
Feather River Canyon in Butte County. The Camp Fire raced up
this canyon like a blowtorch in a paper funnel on its way to
Paradise, incinerating most everything in its path, including
scores of homes. Efseaff is floating an idea that some may

Slurries of mud increasingly threaten the water we drink. This
rush of sediment, known as “debris flow,” is a type of erosion
where mud and boulders in steep catchments suddenly tumble down
the stream channel, often traveling at speeds of several meters
per second. … Last year, California saw mudslides that
destroyed more than 100 homes and killed 21 people.
The California Department of Fish and Wildlife (CDFW) today was
awarded $8.5 million in funding over three years by the
Sacramento-San Joaquin Delta Conservancy to expand its nutria
In retrospect, it’s clear: We’ve misunderstood how rivers work.
They don’t follow wishful parameters of the Army Corps of
Engineers’ 100-year flood guidelines, or the routes we’ve
penciled in between levees, or even the climatic expectations
of the past. A national program that presumes we can
choreograph today the floods of tomorrow is fundamentally
flawed. It’s time to recognize that the rivers will have their
way. Therefore we need to get out of the way.
A beach closure that has been in place for months for the
southern part of the Imperial Beach was extended Sunday to
include the city’s entire shoreline. The San Diego County
Department of Environment Health issued the order to close the
coastline to swimmers as a result of sewage-contaminated runoff
in the Tijuana River.
By late spring, the Pacific jet stream is typically rushing
over the Northwest, but this year its trajectory never shifted
to the north and remains over California, hurling storms from
the Pacific Ocean onshore. Jon Gottschalck, chief of the
operational prediction branch at the National Oceanic and
Atmospheric Administration, says the reason for the jet
stream’s wayward activity are complicated, but he and his
colleagues at NOAA think El Niño is definitely at play.
Residents whose homes were flooded will not be eligible for
financial aid from the Federal Emergency Management Agency
because state officials determined the amount of damage was

Napa County’s latest watershed symposium came at a time when
tensions are high over how to protect trees and reservoirs in
the area’s mountains. Close to 200 people from various
backgrounds came to Copia on Thursday for an A-to-Z look at
what’s happening in the watersheds. Scientists, elected
officials, wine industry members and citizen activists all
A new category of El Niño has become far more prevalent in the
last few decades than at any time in the past four centuries.
Over the same period, traditional El Niño events have become
more intense. This new finding will arguably alter our
understanding of the El Niño phenomenon. Changes to El Niño
will influence patterns of precipitation and temperature
extremes in Australia, Southeast Asia and the Americas.
Reforestation will improve watershed conditions by restoring
severely burned areas to forested conditions, reducing
sedimentation and turbidity, and improving water quality for
downstream users. It will also improve habitat by providing
stabilization that reduces erosion of stream banks and meadows.
There are actions we can take today that will reduce the
pressure on struggling sea life and protect the industries and
communities that rely on a healthy ocean. … The Ocean
Resiliency Act of 2019 (Senate Bill 69) tackles a range of
threats facing our fisheries, from fertilizer runoff that feeds
harmful algae to sediment flowing downstream from logging
operations that violate clean water rules, which can silt up
the spaces between rocks where baby salmon shelter and feed.
Snowpack in every part of Colorado’s high country is sporting
layers of dust, according to a new statewide survey of the
state’s winter accumulation. … Dust is darker than snow. Just
like a black T-shirt on a sunny day, it absorbs more sunlight,

While the state agency responsible for policing Los Angeles
County’s polluted urban and stormwater runoff boasts
significant progress in its monumental task, a National
Resources Defense Council report this week criticizes the
water-quality panel for lackluster enforcement.
A group of Democratic senators and San Diego County-based
congressional representatives sent a letter to multiple federal
agencies Tuesday urging them to address sewage runoff in the
Tijuana River … Local and state officials as well as
environmental activists have decried the condition of the
Tijuana River for years, which regularly causes beach closures
along the county’s coastline, particularly after heavy rain.
Every day, an estimated 100 million gallons of runoff
contaminated with various pollutants flows through L.A.’s
massive storm drain system to foul our rivers, creeks and,
ultimately, our coastal waters. … Today, NRDC urged the

Water Quality Control Board to address this serious public and
environmental health threat.
The development of the Arcata Marsh as an integral part of
wastewater treatment in Arcata was the primary focus of two

discharged into Humboldt Bay. On May 7, Gearheart … will be
honored by the Environmental Law Institute at its annual awards
dinner in Washington, D.C.
Tracy Hall says she’s lucky to have friendly neighbors who
allow her to live in an RV on their property while water laps
at a temporary barrier on the edge of her property. But Hall

Lemmon Valley filled with stormwater runoff and urban effluent.
One of California Gov. Gavin
Newsom’s first actions after taking office was to appoint Wade
Crowfoot as Natural Resources Agency secretary. Then, within
weeks, the governor laid out an ambitious water agenda that
Crowfoot, 45, is now charged with executing.
That agenda includes the governor’s desire for a “fresh approach”
on water, scaling back the conveyance plan in the Sacramento-San
Joaquin Delta and calling for more water recycling, expanded
floodplains in the Central Valley and more groundwater recharge.
In California, the amount of water exiting aquifers under the
state’s most productive farming region far surpasses the amount
of water trickling back in. That rampant overdraft … has
ignited interest in replenishing aquifers in California’s
Central Valley through managed flooding of the ground above
them. But until now there has been no reliable way to know
where this type of remedy will be most effective.
The February storms that swelled the Russian River to its
highest level in more than two decades did $23 million in
damage to Sonoma County roads, including more than 100
landslides and slipouts, leaving county crews and contractors
with a Herculean repair job that will take months to complete.
The National Flood Insurance Program provides coverage to more
than 5 million households and small businesses across the
United States, including more than 229,000 in California. The
program has been hard hit by payouts from major flood disasters
in recent years and is heavily in debt. The Federal Emergency
Management Agency (FEMA), which houses the program, has
recently announced significant changes. We talked to Carolyn
Kousky, a flood insurance expert at the Wharton Risk Center at
the University of Pennsylvania … about the program.
Frustration was evident, whether it was from a flooded
homeowner or a government agency trying to explain its
processes during Wednesday’s “listening session” regarding
flooding in north Chico. … Despite the anger, there seemed to
be some progress, whether it was the cleaning of Rock Creek
west of Highway 99 by the Rock Creek Reclamation District, or
more property owners funding efforts themselves. Lucero
