Motorists should expect full closures of Topanga Canyon Blvd (State Route 27) the week of April 8 through April 11 from 10:00pm to 5:00am, said the California Department of Transportation (Caltrans) in an announcement. The closure will take place from the Pacific Coast Highway to Grand View Dr., near Jalan Jalan Imports, for an emergency repair and restoration project of the slopes after a winter of hard rains that have eroded the embankments along SR27 in Topanga.

CalTrans warns traffic will be diverted to Malibu Canyon, the 101 and Las Virgenes as alternate routes. Motorists should expect long delays and are strongly advised to use these alternate routes or avoid Topanga Canyon Blvd altogether. The Town of Topanga is still open for business during the closures. Motorists can access Topanga from the Valley side of Topanga Canyon Blvd to visit the businesses of Topanga.
Drivers can check traffic conditions before they leave by visiting the Caltrans Quickmap

Since the height of the industrial revolution, humans have been emitting pollution at unprecedented rates. Pollutants known as “greenhouse gases” (GHGs) are absorbed by the Earth’s atmosphere and act like a “heating blanket.” The amount of GHGs in the Earth’s atmosphere is directly linked to how much, and how fast, the earth warms—and thus, how much our climate changes.

The world is already witnessing climate change impacts such as record-setting temperatures, catastrophic hurricanes, melting ice sheets and glaciers, flooding, drought, increased forest fires and other extreme weather. Climate change is predicted to bring more intense storms and increased sea levels.1 Our local coastlines are being impacted in several ways:
“The ocean is 30% more acidic than it was in 1750. Drastic changes in ocean chemistry are detrimental to marine life, including the impairment of crustaceans’ abilities to form protective shells.”Stefanie Sekich-Quinn

Shrinking beaches: Scientists predict sea levels could rise up to six feet by 2100.An increase this large will swallow beaches—impacting public access, recreation, healthy ecosystems, and community infrastructure. In addition to sea level rise, increased storms will also chip away at our beaches. 2
Pollution: More rain can result in sewage overflows and urban runoff cascading into the ocean. In addition, sea level rise and coastal inundation can overload and undermine wastewater infrastructure—causing malfunctions that result in more pollution.
Ocean Acidification: Over 25% of carbon dioxide emitted by burning fossil fuels is absorbed by ocean water.3 As a result, high concentrations of carbon dioxide are causing the oceans to acidify at rapid rates. In fact, the ocean is 30% more acidic than it was in 1750.4 Drastic changes in ocean chemistry are detrimental to marine life, including the impairment of crustaceans’ abilities to form protective shells.
Surfing and other recreation: Rising seas will contribute to extreme tides that will impact how waves break. In areas where the seafloor is sandy and flat (a beach break), the wave may break further inshore, thus changing the size and shape of the wave. In areas where the seafloor is uneven and rocky (a point break), higher sea levels will inundate the break, leaving less area for the wave to form and increasing the possibility that the wave might not break at all.5In addition, ocean temperatures and ocean acidification are killing corals around the world; and in places where surfing is formed by coral reefs those surf spots will go away. Of course, diving experiences will certainly be impacted as reefs die and biodiversity is compromised.
Damaged infrastructure: Sea level rise and increased storm activity will damage community infrastructure (homes, roads, municipal buildings, etc.).As communities become more aware of the impacts of climate change on their beaches, they may choose to employ reactionary response measures, such as building seawalls, which can greatly impact beaches, ecosystems and actually exacerbate erosion.
Just last week, the United Nations Intergovernmental Panel on Climate Change released a report concluding that drastic climate change impacts are now expected to occur much faster than previously predicted – as soon as 2040. Even if humans manage to keep the Earth’s temperature from increasing by 2 degrees C (the magic number assigned by scientists to avert dire consequences), major impacts will happen regardless. 6
While predictions about climate change are daunting, there are several actions we can all take to mitigate and adapt to climate change. For example, the Surfrider Foundation is encouraging local communities to support renewable energy efforts such as “Community Choice Energy” where citizens can dictate what type of energy they want to fuel their community—purposefully weaning off fossil fuels.
Other mitigation efforts include installing “Ocean Friendly Gardens” to trap greenhouse gases in the soil. In addition, we encourage local communities to improve coastal resiliency by restoring dunes and wetland—building a stronger buffer against storms and rising seas. However, one of the most effective measures communities can take is to proactively plan for sea level rise and extreme weather events by improving local land use plans, zoning regulations, and rebuilding standards. We no longer have the luxury of continuing to rebuild in areas that have repetitive flood and storm damage at the expense of nature and taxpayers.
Communities should also call upon their elected officials to implement meaningful climate change policies at the local and federal levels. For example, Surfrider has an action alert asking the Trump Administration to honor the Paris Agreement which aims to curb climate change. We also have an action alert urging elected officials to reform the National Flood Insurance Program so taxpayers are not spending money on rebuilding in harm’s way and communities are incentivized to rebuild in “climate-smart” ways.
Finally, there are many actions people can do on a personal level to curb climate change, such as to carpooling, using mass transit, walking or biking to destinations and buying a low carbon vehicle. In addition, people should limit or stop purchasing plastic—plastics are made from petroleum products (i.e. fossil fuels) and take a tremendous amount of energy to create and dispose of. It is estimated 29 percent of U.S. greenhouse gas emissions result from the manufacturing and final disposal of plastic goods. Upgrade your light bulbs by replacing incandescent light bulbs with more efficient fluorescent or LED lights. Weatherproof your home to reduce drafts and air leaks by caulking, using insulation and weather stripping to save energy.
Another fun way people can help bring awareness to climate change is to ride a Smartfin. The Smartfin is a surfboard fin with sensors that measure multiple ocean parameters including temperature, location, and wave characteristics (and in the future, it will read pH levels related to ocean acidification). Using the data collected with Smartfin will help scientists to better understand trends in ocean warming, acidification and mobilize our communities to act and combat problems caused by climate change.
If we all work together and proactively plan ahead we can help avert climate change impacts and protect our wallets. According to the National Institute of Building Sciences, every dollar invested in preparedness and resiliency saves six dollars in costs down the road.7We owe it to future generations to be proactive with climate change so they don’t suffer our consequences.The time to act is now!

Climate change has a direct impact on Topanga Creek and the waterways it drains into, most notably the Santa Monica Bay. A study published in the Proceedings of the National Academy of Sciences journal projects that sea levels may rise anywhere from 11 to 52 inches by 2100, depending on how much heat-trapping gas we emit. That could be detrimental to Los Angeles’ coastline and Topanga Beach. As the planet warms, seawater levels will rise, ice sheets will melt and water levels will change, flooding beaches in some areas and causing drought in others.
Changes in rainfall may alter when and how much sediment washes down rivers and creeks. Topanga Creek out to the sea may experience changes related to sea level, seawater temperature, and other ocean dynamics, contributing to the erosion of beaches. Studies that model these complicated processes have shown that climate change may alter where “erosion hotspots” occur along the California coastline. For Los Angeles this could also affect coastal infrastructure, including two wastewater treatment plants, two power plants, and the Port of Los Angeles.

A lack of rain and high temperatures are also exacerbating wildfires in our region. The combination of low humidity, sparse precipitation, dense and dry brush, and Santa Ana winds are a huge threat to Topanga and the Santa Monica Mountains. Five of the 20 worst fires in California history have occurred since September, when 245, 000 acres in Northern California burned. Topanga is especially susceptible to this type of threat due to a high density of dry brush within and surrounding the canyon. More wildfires and hot days could lower air quality.
Because preserving water quality is essential to protect both human populations and natural ecosystems, it is imperative to assess these impacts, and to develop strategies to adapt to the upcoming changes and mitigate their effects on our watershed. Topanga Creek used to be an integral part of the Canyon’s landscape and ecosystem, but the drought has led to Topanga Creek remaining unusually dry and inhibiting the birth of endangered steelhead trout and tidewater goby.
The mission of the Topanga Creek Watershed Committee is to refine and develop consensus-based, voluntary watershed-protective measures and strategies that effectively minimize negative impacts to the watershed and all who inhabit it. The Watershed Committee is inclusive of all stakeholders in the watershed and is free and open to all interested community members. Historically organized according to a Coordinated Resource Management Plan (CRMP), our grassroots organization continues to ensure that all participants have an equal voice in the process.
Topanga Creek is the third largest drainage basin into the Santa Monica Bay and manifests the greatest biodiversity. We have not yet lost our Creek, and the goal of the Committee is to see that not only is it protected, but also enhanced so that it can once again support endangered steelhead trout and other important residents of the Canyon. Topanga Creek is classified as an interrupted stream, and the Topanga Watershed covers approximately 12,748 acres (18 square miles). 11,082 acres are undeveloped or held by state and federal park agencies as part of the Santa Monica Mountains National Recreation Area.
Climate change is an all-encompassing global issue. The consequences will not discern between political boundaries or economic class. It is a global problem that has been slowly coming to the forefront of societal considerations. The global temperature has risen significantly each year as humans continue to industrialize without consideration of consequences. Studies have shown that the amount of carbon dioxide in the atmosphere has doubled since the 1960’s. The reason climate change is an inevitable global concern is that there is a prevalence of inaction and skepticism among far too many across the world.
One big problem that exists today is that government views immediate economic gain as being more important than the steady increase in global temperature. A majority of big businesses are tied in problematic ways to politicians and governmental organizations. Money has often served to corrupt political systems, including in some of our most vaunted democracies- places that are supposed to consider people over profit. This hard truth has led individuals to take matters into their own hands; both 2017 and 2018 have been remarkable years for profound, yet peaceful, protest. This surge in individuals voicing their concern has occurred in conjunction with Donald Trump’s time in office. Trump has entered office and swiftly set back environmental progress in the United States. He actually announced on his fourth day in office that he intended to expand fossil fuel production and roll back a raft of some of our most important environmental regulations, including the Endangered Species Act.
The truth is that climate change is real. Nine out of ten scientists devoted to studying climate patterns agree; it’s undeniable. Sea glaciers are melting at a tremendous rate. Climate change is causing an increased air temperature, causing moisture levels in air to increase in some places while reducing moisture in others. The effects of these extreme ecological changes have already begun to affect plants and animals in places that are now either too hot or too cold for what they can evolutionarily manage.
The monetary stability that exists in energy production is a direct result of the scalpel taken to regulations intended to protect resources and natural landscapes. The disregard towards ecological protection is a growing concern for the public because, if changes are not made within energy production, society will be faced with major loss. Alternative clean energy is a huge and growing market. Energy alternatives are necessary for humans to shift dependency off non-renewable fossil fuels that worsen climate change.
Local grassroots momentum and lobbying efforts play a necessary role alongside regulation efforts because the reality is that often policy regulation will not be enacted soon enough to solve the problem. That is why the Topanga Creek Watershed Committee was created, to protect our community from these overarching political policies. Local actors require a consensus in order to demand action from the government. Regulations by themselves are not enough to create major change, however. You need people and businesses to want to do the right thing of their own accord.
The facts are irrefutable; global sea levels are rising. Plants and wildlife are dying off with all the stress from heat and drought. Rising temperatures create agricultural fragility and directly affect environmental and public health. Public participation is crucial to spread awareness and initiate change, because politicians manifest change only when the public rises up and demands it.
There is a very real risk of a global catastrophe if global warming is left unchecked. Potential international resource concerns, such as oceanic acidification leading to the mass death of coral and plankton, which is the basis of the Earth’s food chain, along with the collapse of the tropical rainforests, and the melting of ice sheets, could cause a cataclysmic rise in worldwide sea levels. The population is growing steadily; in half a century, the world population has grown from 3 to 7 billion. The industrialization of agriculture and the food system has been one way that many countries have tried to sustain the growing population. But industrial agriculture comes at a steep climate cost.
From an economic standpoint, carbon fees would go back to citizens, meaning that if businesses did not become more energy efficient and start converting to green energy, they would become less competitive and lose market share. The assumption that we must choose between the economy and a safe climate is false. A carbon fee that returns revenue to households could actually stimulate the economy and spur job growth in the clean technology sector because a comforting reality is that consumers dictate the economy. Once these changes are implemented and succeed, more nations would adopt the system and global demand would bring green technologies to mass market faster, driving down costs and making the transition to a green economy easier for everyone.
Climate change presents a direct threat to security through its effect on the infrastructure that stabilizes our nation’s security. A majority of Americans support taking action to address the threat of global warming, but due to great opposition from officials in Congress, legislation to address climate change has yet to be implemented.
Did you circle October 1 on your calendar? It wouldn’t surprise me if you did, given the environmental savviness of the average Topanga resident. For those of you who may have missed its significance, October 1 marks the new water year, that is, the day California re-starts annual precipitation measurements.
What’s harder to miss is the evidence that climate change is real, is accelerating, and that it demands our action now. Catastrophic storms—most recently, Hurricane Michael in the Florida Panhandle—are coming faster and more furious than ever. Paradoxically, dry areas are becoming drier. Just a few weeks ago, the Intergovernmental Panel on Climate Change (IPCC), meeting in South Korea, warned that if greenhouse gas emissions continue at the current rate, the atmosphere will warm up by as much as 1.5 degrees Celsius (2.7 degrees Fahrenheit) above preindustrial levels by 2040, intensifying droughts and poverty.
“One of the key messages that comes out very strongly from this report is that we are already seeing the consequences of 1 degree Celsius of global warming through more extreme weather, rising sea levels and diminishing Arctic sea ice, among other changes,” the IPCC said in its report.
Closer to home, the California Department of Water Resources noted that for the water year just ended, the statewide snowpack was just 58 percent of average by April 1—a steep decline from the previous water year when snowpack reached 159 percent of average. In addition, much of Southern California ended up with half or less than half of average rainfall. The Topanga area (as recorded in Woodland Hills) saw only 5.98 inches of rain, 34 percent of the normal rainfall for the water year. That made it the fourth driest year on record (2006-2007 was the driest, with only 5.14 inches of rain recorded), according to the National Weather Service. Also, as you’re well aware, the state was besieged by record-breaking wildfires during the dry 2017-2018 water year. All of that shows that California is warming.
And while it’s true that most California reservoirs currently have near- or above-average levels of water, the well-established shift toward a warmer climate with diminished snowpack means that we cannot rely on such abundant reservoirs.
That’s why it was encouraging to see Governor Jerry Brown earlier this year sign into law legislation establishing statewide water efficiency standards. Senate Bill 606 and Assembly Bill 1668 strengthen the state’s water resiliency in the face of future droughts with provisions that establish lower per-person water use goals, incentives for water suppliers to recycle water, and requires both urban and agricultural water suppliers to set annual water budgets and prepare for drought.
It’s hard to legislate considerate behavior, I know. And it can be frustrating when you, as a thoughtful Topangan, have embraced the muted greens and browns of your xeriscape garden only to see folks in neighboring communities drowning their fescue lawns with potable water.
Still, I implore you to try. As we encounter the effects of climate change and growing, economically developing populations, we must advance a more diversified approach to water supply reliability that takes into account regional natural assets, such as groundwater basins and seawater desalination, and supplemental systems that include reservoirs, stormwater capture and recycled water. The costs of inadequate water supplies are steep for today’s highly condensed urban areas and are simply not an option.
California is working to adapt to changing conditions and rapidly becoming a model for the kind of balanced water storage and conveyance systems that other cities, states and nations need.
As you may know, about two-thirds of our state’s precipitation falls in the north while roughly two-thirds of our population resides in the south. That means California must rely on an intricately plumbed network of reservoirs, aqueducts, pipelines and pumps as well as out-of-state imports to supply water to major urban centers, agriculture and industry. A major earthquake or failure of a dam or levee could have a profound impact on the water supply to regions hundreds of miles away. In addition, the two major sources that feed the aqueduct systems, the Colorado River and Northern Sierras, are themselves strained by climate change, causing swings in their annual reliability.
Faced with these vulnerabilities, California has set out on an urgent path toward ensuring water security not only for today’s users and conditions, but for future users and conditions as well. Agencies across the state are implementing new techniques and technologies in an effort to diversify supply portfolios to include not just traditional reservoir surface storage, but also underground aquifer storage, stormwater capture, recycled wastewater, and brackish and ocean water desalination where viable. None of these prescriptions alone is a silver bullet. But combined they offer reliable and flexible sources of supply to meet long-term needs. The focus is on resilience and sustainability, and we are looking to other countries, such as Israel and Australia, that have faced similar challenges for lessons learned.
One area in particular in which California and local agencies such as the West Basin Municipal Water District, where I have served on the board of directors since 2014, have made great strides is water reuse—recycling treated wastewater for irrigation, industrial use and groundwater recharge. The drought of the late 1980s and early 1990s led to the development of West Basin’s world-renowned Edward C. Little Water Recycling Facility in Los Angeles County. The facility recycles some 40 million gallons of water per day and distributes it through a network of more than 100 miles of distinctive purple pipes.
Where West Basin is unique is that it produces five types of recycled water that are specific to the needs of our customers. They include:
•Irrigation water: sewer water that has been filtered and disinfected for industrial and irrigation use, such as golf courses, street medians, and office and shopping centers
•Cooling tower water: sewer water that has been processed to remove ammonia for water to run boilers and convey heat to cooling towers
•Seawater barrier and groundwater replenishment water: sewer water filtered by microfiltration and reverse osmosis membranes and disinfected for use in maintaining a barrier against seawater intrusion and augmenting local well water supplies
•Low-pressure boiler feed water: sewer water filtered by microfiltration and reverse osmosis membranes for use as low pressure boiler feed water
•High-pressure boiler feed water: sewer water filtered by microfiltration membranes and passed through reverse osmosis membranes twice for use as feed water for high pressure boilers.
The use of recycled water during the 2012–2017 historical drought helped insulate West Basin from mandated conservation cuts by the state and allowed our customers to continue normal operations in the midst of severe drought. Today, working with our contract operator SUEZ North America, we continue testing new recycled water technology that will benefit the entire water industry and are in the process of expanding the plant’s capacity to produce additional recycled water, further improving drought resilience and lowering dependence on imported potable water.
None of us can fully predict how much precipitation the new water year will bring. But computer modeling suggests that while there’s a 33 percent chance of above average rainfall for parts of Topanga Canyon this winter, Southern California—as well as vast swatches of the Southwest—will see a lingering drought. Regardless, there literally will be no sea change that will make Southern California lush and green anytime soon.
Where does that leave us? Like it or not, it leaves us where we were before—only now it’s more critical than ever. So we must all do our part to confront the challenges of climate change that includes continued water conservation and efficiency, as well as water reuse methods that provide secure water supplies while countering the erratic precipitation patterns we now face.
