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.
UC Berkeley engineers have developed a mineral-coated sand that
can soak up toxic metals like lead and cadmium from water.
Along with its ability to destroy organic pollutants like
bisphenol A, this material could help cities tap into
stormwater, an abundant but underused water source.
A state inspection found 12 flaws in Poway’s drinking water
delivery system less than three months before the city’s
precautionary boil water advisory. City officials remain
adamant that the issues raised by the inspection had nothing to
do with the nearly week-long advisory that ended Dec. 6.
With a low rumble from a large pipe, water began flowing into a
dirt basin at 25th Street West and Elizabeth Lake Road Thursday
morning, christening the Upper Amargosa Creek Recharge Project
and marking the debut of a new water storage endeavor in the
Valley. Inside the basin, water flowed from holes in a round
structure to begin flooding the bottom, where it will begin to
percolate through the soil to the aquifer beneath.
Two wildlife advocacy groups Wednesday announced their intent
to sue the Riverside County Flood Control & Water Conservation
District, as well as other regional and federal government

heavy metals and other contaminants regularly flow from Tijuana
to San Diego.
Urban flooding is increasing in the Bay Area for four main
reasons: California’s naturally variable precipitation
patterns, climate change increasing precipitation extremes,
population growth, and aging and insufficient infrastructure.
Researchers combed through six years of data, from 2012 to
2018, to examine how L.A. County has mitigated the issue, most
visible in the 72-hour aftermath of rainfall but persists
during dry weather in the form of runoff from driveways and
sidewalks. As it turns out, not much has been done, largely
because of a lack of transparent requirements when it comes to
the monitoring of stormwater pollution by various
The City Council will certify the Water Quality and Flood
Protection Initiative at its Dec. 17 meeting after Alameda
property owners voted in favor of a fee hike. … The increased
fee will fund repairs and new pump stations, which is vital to
combat potential flooding as sea levels rise; improve lagoon
systems, enhance street sweeping procedures and maintain and
install new trash capture devices. These devices are key to
keeping the shoreline free of trash and other debris.
A state official said Wednesday he intends to notify the city
of Poway that its water storage reservoir is out of compliance,
a situation he said directly contributed to last week’s storm
water overflow that has left the entire community under a
boil-water advisory and temporarily shuttered nearly 200
Rains caused storm drains to back up into Poway’s water
treatment facility, officials said. Crews are working around
the clock to clean and flush the system, which may take two to
five days before the water is declared safe. The county health
department ordered the closing of all restaurants in the city
and residents are being advised to boil their tap water before
drinking it or using it for cooking, city officials said.
Called Bending the River Back Into the City, the project will
churn with water from the river, siphoning a fraction of it out

The Environmental Protection Agency fanned the flames of an
ongoing dispute with San Francisco on Thursday, reaffirming its
stance that the city’s water agency improperly discharges
wastewater into the ocean. In a letter to the San Francisco
Public Utilities Commission, EPA officials reiterated their
assessment that the city was out of step with its wastewater
discharge permit, which regulates water quality standards.
An unlikely coalition in California — including
environmentalists, law enforcement agents, politicians,

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

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.
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.
In case you’ve noticed some of the storm drains in the City of

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 blue ocean has turned a rusty red in Manhattan Beach — but
what is causing this change in color? The red tide, as it’s

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

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

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

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.
Two days of above-average spring rainfall in the North Bay have

level rise, including the Oakland Coliseum and Jones Avenue,
where [UC Berkeley professor Kristina] Hill and her students
now stood, more than a mile from San Leandro Bay. In fact, she
added, rising groundwater menaces nearly the entire band of
low-lying land around San Francisco Bay, as well as many other
coastal parts of the U.S.
By allocating $1 million last week toward a creek restoration
project set to rejuvenate threatened and endangered species and
reduce flooding in Pescadero, county officials locked in
funding needed to begin a dredging effort experts expect will
give the Butano Creek a chance to reset.
But the river remains an unpredictable force, one that could
give rise to even more destructive floods in an era of
increasingly extreme weather, experts say. … County
Supervisor Lynda Hopkins has her sights on the opportunities to
tame floodwaters in the river’s middle reaches, starting near
Windsor and upstream, where it broadens and meanders more
freely in a floodplain less constricted by roads and other
Although Santa Monica may be the most aggressive Southern California water provider to wean itself from imported supplies, it is hardly the only one looking to remake its water portfolio.
In Los Angeles, a city of about 4 million people, efforts are underway to dramatically slash purchases of imported water while boosting the amount from recycling, stormwater capture, groundwater cleanup and conservation. Mayor Eric Garcetti in 2014 announced a plan to reduce the city’s purchase of imported water from Metropolitan Water District by one-half by 2025 and to provide one-half of the city’s supply from local sources by 2035. (The city considers its Eastern Sierra supplies as imported water.)
Imported water from the Sierra
Nevada and the Colorado River built Southern California. Yet as
drought, climate change and environmental concerns render those
supplies increasingly at risk, the Southland’s cities have ramped
up their efforts to rely more on local sources and less on
Far and away the most ambitious goal has been set by the city of
Santa Monica, which in 2014 embarked on a course to be virtually
water independent through local sources by 2023. In the 1990s,
Santa Monica was completely dependent on imported water. Now, it
derives more than 70 percent of its water locally.
Since the rainy season began in earnest in January, County
Flood Control has been operating almost constantly to keep its
debris basins clear and ready for the next onslaught. Much of
the accumulating debris is due to 2017’s Thomas Fire, which
burned more than 280,000 acres in the back- and front-country
behind Montecito, Carpinteria, and the western part of Ventura
This is among the hottest of Napa County’s hot potatoes. That’s
because it strikes such nerves as possible, further constraints
on new vineyard development in local hills and a perceived need
in some quarters to do more to protect water quality in local
Many no longer recall the Great Midwest Flood despite its
record-breaking precipitation, flooding and $13 billion price
tag. Sure, 1993 seems like a long time ago, but I believe the
reason the flood has left most people’s memory is because, over
the last 25 years, the nation has experienced one devastating,
record-breaking flood after another. Our memories are diluted
by the frequency of such events.
A powerful “atmospheric river” storm is expected to pummel
Northern California starting Tuesday night and deliver heavy
rain, gusty winds, downed trees, power outages and rough
driving conditions Wednesday and Thursday. … The storm
should bring up to 5 feet of new snow in the Sierra Nevada,
forecasters said. The National Weather Service announced
flash-flood and high-wind warnings for the Bay Area, along with
Santa Cruz and Monterey counties.
Anyone who has been on Balboa Island during a hard rain knows
the streets can flood. The city of Newport Beach is
considering replacing the island’s 1930s-era drainage system
with several automated below-ground pumps. That would save on
labor and costs associated with manually opening the tide gates
at the end of streets and sending out portable pumps and
slicker-clad city workers to dump excess storm water into the
Early last year, construction started on a $90 million project
to build seven miles of setback levees and floodplains to
protect Hamilton City from floods on the Sacramento River. …
The new barriers are much farther from the riverbanks—as far as
a mile away in places. In some respects, the concept is
absurdly simple: During heavy rains or spring snowmelt, rivers
need room to expand; moving levees back from riverbanks
provides it. Setback levees not only reduce the need for newer
and larger dams and levees, but also restore the natural
State water quality officials cautioned the public not to drink
or cook with untreated surface water from streams throughout
the Camp Fire burn area after bacteria and other contaminants
were detected in water samples. … Laboratory analyses of
surface water samples found concentrations of bacteria
(E.Coli), aluminum, antimony and some polycyclic aromatic
hydrocarbons (PAHs) that exceeded water quality standards for
For decades, the New River has flowed north across the
U.S.-Mexico border carrying toxic pollution and the stench of
sewage. Now lawmakers in Washington and Sacramento are pursuing
legislation and funding to combat the problems. “I feel very
optimistic that we’re going to be able to get some things done
on the New River issue,” said Assemblymember Eduardo
Another Pacific storm was set to hit California on Wednesday,
bringing a threat of mudslides to the site of the deadliest
wildfire in state history and a rare blizzard warning in the
Sierra Nevada. An evacuation warning was in place into Thursday
morning for Pulga, a canyon community in Northern California.
Its neighbor, the town of Paradise, was virtually incinerated
two months ago by the Camp Fire that killed 86 people and
destroyed nearly 15,000 homes.
Arcadis has announced it will partner with Kiewit
Infrastructure West and PERC Water to serve as the progressive
design-build team for the Sustainable Water Infrastructure
Project (SWIP) in the City of Santa Monica, Calif. Currently,
the city partially relies on imported water to meet its
water needs. This project will allow the city to take a major
step toward water independence, supporting existing programs
designed to create a sustainable water supply
The Governor’s Office of Planning and Research has spent
five years drafting a comprehensive update to 30 sections of
the California Environmental Quality Act (CEQA)
guidelines. Several changes to the Guidelines address two
hot button topics: global climate change and statewide
affordable housing shortages. Many of the changes will
significantly alter the application of CEQA to future projects.
A storm will slide into Southern California with soaking rain
by the weekend, putting burn-scar areas at a renewed risk for
life-threatening flooding and mudslides. People living
near or downhill of the Creek, La Tuna, Thomas, Woolsey and
Whittier burn areas should make sure they stay up to date on
the latest forecast and heed all evacuation issues that are
ordered by local officials.

There’s every reason to expect that 2019 will be far better,
largely because of Measure W, which was passed by voters in

Cross-border water pollution between Tijuana and South San
Diego is not new, but in recent years, the problem has grown
worse. The reasons are complicated: There is Tijuana’s
topography, with its steep hillsides and canyons that drain
towards the border; the factories that get away with illegal
dumping; the city’s rapid population growth, aging wastewater
infrastructure and inadequate garbage collection. In the U.S.,
funding cuts to the Environmental Protection Agency have
prevented improvements to the Borderlands’ sewage system.
Pacific Gas and Electric Co. has agreed to protect San
Francisco and Humboldt bays from runoff of dangerous chemicals
on utility poles in a settlement with an environmental group.
… The suit said oil and wood waste from poles stored at the
yards washed into the bays, damaging the environment and
endangering human health and wildlife.
Farmers in the Central Valley are broiling about California’s plan to increase flows in the Sacramento and San Joaquin river systems to help struggling salmon runs avoid extinction. But in one corner of the fertile breadbasket, River Garden Farms is taking part in some extraordinary efforts to provide the embattled fish with refuge from predators and enough food to eat.
And while there is no direct benefit to one farm’s voluntary actions, the belief is what’s good for the fish is good for the farmers.
Los Angeles County supervisors voted Tuesday to place a
property tax before voters in November to raise money for
projects to capture and clean storm water. The measure would
allow the county to levy a tax of 2.5 cents per square foot of
“impermeable space” on private property.
Sixty percent of California’s developed water supply
originates high in the Sierra Nevada mountains. Our water

As we continue forging ahead in 2018
with our online version of Western Water after 40 years
as a print magazine, we turned our attention to a topic that also
got its start this year: recreational marijuana as a legal use.
State regulators, in the last few years, already had been beefing
up their workforce to tackle the glut in marijuana crops and
combat their impacts to water quality and supply for people, fish
and farming downstream. Thus, even if these impacts were perhaps
unbeknownst to the majority of Californians who approved
Proposition 64 in 2016, we thought it important to see if
anything new had evolved from a water perspective now that
marijuana was legal.
California voters may experience a sense of déjà vu this year when they are asked twice in the same year to consider water bonds — one in June, the other headed to the November ballot.
Both tackle a variety of water issues, from helping disadvantaged communities get clean drinking water to making flood management improvements. But they avoid more controversial proposals, such as new surface storage, and they propose to do some very different things to appeal to different constituencies.
Taxpayers may not realize it, but they foot the bill as their

The thousands of miles of concrete channels diverting street
water from the San Gabriel and Los Angeles rivers represent the
last major water project in Los Angeles County, built almost
100 years ago. On Thursday, Dave Sorem, owner and vice
president of Mike Bubalo Construction Co., showed off the first
of a second wave of street-water projects that elevate what is
essentially water pollution into a drinkable water source.
Precipitation carrying tainted water through the Tijuana River
into the Pacific Ocean triggered beach closures Tuesday evening
from the international border to Seacoast Drive in Imperial
Beach. … The pollution from stormwater runoff adds to
spills from aging pipes and potentially hazardous discharges
from the deteriorating San Antonio de Los Buenos sewage
treatment plant in Punta Bandera, located about six miles south
of the border.
It’s been thought for decades that stormwater runoff is the
major source of bacterial pollution in the county’s rivers,
bays and beaches — triggering swimming advisories up and down
the region’s shoreline for 72 hours after it rains. However,
the greatest source of dangerous pathogens flowing from these
urban waterways into the ocean may actually be coming from
Bioswale projects on medians and other surfaces along a handful
of the east San Fernando Valley’s major roadways could be

Despite spending millions of dollars over the years on garbage
cleanup, Oakland has the Bay Area’s worst record for limiting
the rubbish that pollutes creeks, lakes and the bay, according
to the San Francisco Bay Regional Water Quality Control Board.
The flow of waste violates mandates set by the board to reduce
storm drain litter this year by 70 percent compared with 2009,
a goal that Oakland is far from meeting.
Looking to tap property owners, the Los Angeles County Board of
Supervisors Tuesday approved moving forward with a plan to

apparently has been a concern for more than a decade.
Of the roughly 300,000 acres in the city of Los Angeles, more
than 2,000 are alleyways that cut through city blocks. And
because they’re mostly paved, they do little to capture one of
the city’s most prized resources: water.
With this year’s storms helping to refill the Sacramento
region’s lakes and reservoirs, local water district officials
and state regulators are diverting and percolating stormwater
from Cache Creek into the Yolo County canal system to recharge

contaminated with harmful bacteria.
For nearly four years, cities in Los Angeles County have voiced
complaints that permits required to rid toxic chemicals and
bacteria from storm water imposed staggering costs that could
bankrupt smaller cities. On Tuesday, two state senators from
Sacramento heard their cries.

After a year in which Californians cut water use by 25 percent,
storm water has become the next front in what amounts to a
fundamental restructuring of Southern California’s relationship
with its intricate water network.
A long arm across Rainbow Harbor prevented piles of detritus
from landing on local shores and floating into the sea earlier
this month, when heavy rains soaked the region and sent tons of
trash and debris downstream from cities along the Los Angeles
River and into Long Beach.
In an effort to restore California’s desperately depleted
ancient aquifers, scientists are testing an approach that
seizes surplus winter rain and delivers it to where it’s most
useful: idle farms and fields.
The State Water Resources Control Board approved a broad plan
Wednesday for capturing more rain. The regulator is launching a
road show this month to explain how it will dole out $200
million for projects to collect rain, part of a $7.5-billion
water bond voters approved in November 2014.
At a meeting that lasted all day, the San Diego Regional Water
Quality Control Board adopted a new program focused on
incentivizing jurisdictions to create innovative plans for
cleaning up local watersheds.
Among the devastating effects of the low pressure storm system
that pummeled South Carolina over the weekend was the heavy
damage the record-breaking rains caused to water transport and
treatment infrastructure, and the release of a tide of
By some estimates, hanging onto more stormwater—as opposed to
just cleaning it so it doesn’t wash pollutants into rivers,
aquifers and the ocean—could supply a city such as Los Angeles
with a third to half of the water it needs annually – and
reduce demand for water from up here.
You might have seen them around new buildings and roadways:
little basins and ditches, planted with various small growing
things. They’re designed to stop crud from washing into the
gutters and down the storm drains.
It may not rain much in Los Angeles County, but when it does, a
single storm can send up to 10 billion gallons of water surging
into a vast network of storm channels with a single
destination: the Pacific Ocean.
Amid a worsening drought, California water officials adopted
new rules Tuesday aimed at capturing and reusing huge amounts
of stormwater that have until now flowed down sewers and
concrete rivers into the sea.
California is at a critical moment in deciding how we’ll deal
with stormwater in Los Angeles … and beyond. Next Tuesday,
June 16, the State Water Resources Control Board (State Board)
will consider whether or not it will uphold the current
