Do I need to fill out a waiver?

You can come after 9 am but you might be sad that you didn’t get to pick up as much trash as everyone else. We also may run out of swag before you get there.

Absolutely! Group registration is open to any group of ten or more volunteers and is available at www.folar.org/cleanup-2018. Group organizers should instruct teammates to register, fill out their waiver online, and add their group name to the “Organization” field of the waiver. Make sure you tell everyone on your team to use the same name when noting your group!

I want to organize a group and help get the word out – do you have any fliers or graphics I can download?

We do! You can get everything you need by downloading the CleanUp Organizer Kit, which contains information, graphics, fliers, and suggested social media captions.

Do I need to bring my own gloves?

Join us and spread the word by bringing your friends and family so that we can make just as much of an impact this year!

If you would like to help out even more, you can make a donation online here to support FoLAR as we organize the Great LA River CleanUp – the largest urban river cleanup in the nation. We are also seeking sponsors who share our vision of a clean and vibrant LA River. If your company or organization might be interested in being a CleanUp sponsor, you can contact Development Director Ivana Gomez del Campo at ivana@folar.org or 323.223.0585 for more information about sponsorship opportunities and benefits.

I want to do more! Can I help with setup or operations?

FoLAR is in need of paid event help for the Great LA River CleanUp. This is not glamour work but those who like to be paid to do gratifying labor in the great outdoors and who love FoLAR’s mission of protecting and restoring the LA River are encouraged to apply. 2018 CleanUp dates are 4/14, 4/21, and 4/28. Candidates who can work all of those dates, as well as some dates before and after each CleanUp day, will gain priority. Requirements of the position include having an automobile, valid driver’s license, auto liability insurance, and an ability/desire to drive to event locations as well as (potentially) drive other vehicles; the ability to lift up to 50 lbs repeatedly for extended periods of time; and the ability to multitask. Please send an email introducing yourself to resumes@folar.org with the title: CleanUp Help. Include a paragraph about any similar experience you may have had and indicate your availability for the dates in question. Experience is not required but showing that you’ve successfully worked in such conditions before is helpful.

What will the weather be like?

It’s spring in LA so it can get hot! Make sure to stay hydrated and wear lots of sunscreen.

What should I bring to the CleanUp and what should I wear?

Please wear rugged, outdoor, clothes (including a hat) and shoes. Don’t forget to bring water bottles to stay hydrated and put on plenty of sunscreen.

Will you provide water, snacks, and sunscreen?

We will provide water, snacks, and sunscreen but we encourage you to bring your own – especially water bottles and sunscreen.

Will there be any entertainment?

Of course! Throughout the CleanUp there will be live bands, visiting VIPs, and select sites will host the Los Angeles River Rover!

Is there any cost or ticket price for participating?

No! We welcome everyone to come and participate in the Great LA River CleanUp.

Can I bring my dog?

Yes – the CleanUp is a pet friendly event – some volunteers even bring their lizards! Some sites may have specific rules and regulations, please make sure to observe any that apply to your CleanUp site.

Is it safe to go into the River channel?

There are of course inherent risks to cleaning an urban river, but we make sure all of our volunteers are informed and prepared by giving a Safety Talk before volunteers enter the channel and start cleaning. Because of this preparation and our expertise, FoLAR has been conducting the river cleanup with few incidents for 28 years.

Does anyone spray herbicides or pesticides in the LA River?

US Army Corps of Engineers (USACE) contractors spot-apply herbicide, by hand-held sprayer, on a monthly basis, to non-native vegetation in LA River channel areas only where vegetation cutting/removal has occurred. The herbicide is Roundup Custom, which is an EPA- and DOD- approved aquatic herbicide. The USACE states that the U.S. EPA, based on long-term toxicological tests, has classified glyphosate as Category E for evidence of non-carcinogenicity in humans – the most favorable cancer rating for pesticide active ingredients and one that few other products meet. They have determined the risk is sufficiently low that there is no significant risk of unreasonable adverse effects to humans or aquatic organisms under normal use conditions (including the Corps’ application technique). Studies on mammals, fish and birds indicate that these chemicals do not bio-accumulate in the food chain.

However, due to continued concerns that FoLAR and others have about the use of these chemicals, FoLAR is currently working with community groups, elected officials, and the US Army Corps of Engineers to advocate for improved methods of combatting excess vegetation and invasive species growth. For the past two years, FoLAR has requested that the US Army Corps of Engineers temporarily halt vegetation maintenance and invasive species removal to provide a window for our CleanUp activities to safely take place. In 2017, the USACE provided a window starting March 15, a month before the start of the CleanUp. FoLAR also communicated its concerns with this chemical spraying to Congressman Schiff’s office, which has joined us and community advocates in pressuring the USACE to examine its practice of using a carcinogen recognized in the State of California under Prop 65. This year, FoLAR has requested a two-month window. FoLAR will update our information once an agreement has been reached.

Click here to view FoLAR’s public letters to both Congressman Adam Schiff in 2017 and the US Army Corps of Engineers this year.

Can I participate if I have mobility limitations?

We hope you do! Each CleanUp site has different accessibility challenges so we advise you to visit www.folar.org/cleanup-2018 and pick a site that you’re comfortable with. There’s a way for everyone to help, from hauling trash bags to the dumpsters to passing out snacks and supplies.

Do I have to go in the water or get wet?

Nope! Please stick to the riverbank and sandbars – it’s safer! If you bring waders or want to get wet it’s up to you.

What if it rains?

The CleanUp will be cancelled if it rains within a 48-hour window of the CleanUp day.

Will we be able to clean the whole River?

We wish! Taking care of the LA River is a year-round effort that takes more than just picking up trash. There are lots of ways to get involved, so make sure you’ve signed up to be on our emailing list to receive our monthly e-newsletters – we do our best to keep our community informed about River news and special events!

Who can I contact for more information?

Please reach out to our office by phone at 323.223.0585 or email contact@folar.org.

Where can I learn more about sponsoring the CleanUp?

FoLAR is dedicated to restoring the LA River for the benefit of people and wildlife, but we can’t do it alone. Every year, FoLAR seeks CleanUp sponsors who share our vision of the River as an urban oasis for both communities and wildlife. Sponsor support is needed to cover the many worthy expenses related to organizing the largest urban river cleanup in the country – trained personnel, equipment rentals, transport services, supplies, permits, event insurance, contract services, and volunteer t-shirts and snacks, among many others!

FoLAR’s robust public marketing and outreach campaigns promote our programs and events, and acknowledge generosity of sponsors throughout the year. Depending on the level of sponsorship, benefits include logo placement on event t-shirts and banners, outreach to FoLAR’s 40,000-person database and a highly engaged social media audience of 20,000 Facebook, Instagram and Twitter followers, and complimentary tickets to our fall fundraiser, just to name a few. The CleanUp is widely promoted by the press, corporate partners, and local government offices. For more information, contact Development Director Ivana Gomez del Campo at ivana@folar.org or 323.223.0585.

I’m concerned about the homeless encampments in the River. Is it safe to participate and is the CleanUp respectful of homeless people and their belongings?

Yes, it is safe to participate, in fact thousands have done so each year for 28 years. This year, FoLAR has partnered with Los Angeles Homeless Services Authority (LAHSA) to provide outreach and services to the homeless prior to and during the events, as well as answer any questions CleanUp volunteers may have on the days of the events.



Marissa Christiansen is the Executive Director of Friends of the LA River (FOLAR). Prior to FOLAR, she held roles in policy, advocacy and development at XPRIZE and the Los Angeles County Bicycle Coalition, among others. Her deep abiding love for LA began at USC where she earned her Master’s in Urban Planning [fight on]. Her inner compass and lifelong passion for counter-culture has magnetized her to the nonprofit world. A proud California native, her primary inspiration is the beauty of our natural landscape – gripped by color and texture, obsessed with the unexpected and overlooked. So to help guide the movement centered on LA’s most diversely textured and inconspicuously beautiful resource is basically her dream come true.

Andrea describes herself as a pragmatic idealist and left her early years in investment banking/consulting to bring appropriate business acumen to the task of social and environmental change. She is excited by bold, scalable solutions to systemic challenges. Andrea fell in love with the L.A. River on a tour of it with FOLAR founder Lewis MacAdams. Since then, she has been annoying everyone at FOLAR with her insistence that Long Beach is the center of the universe. When Andrea is not analyzing spreadsheets and creating policy and budgets for FOLAR, she can usually be found near or in the ocean with her husband and their young son.

One of Shelly’s earliest memories is catching a bird in her bare hands. After a weekend birding trip to Mono she was hooked. It’s just one of the reasons she is so passionate about plans and projects that re-create wetland habitat along the Los Angeles River. Shelly shares this enthusiasm at any opportunity whether it’s leading a tour, running a field trip activity with elementary school children or meeting a community member on the Los Angeles River Rover. If you see Shelly out on the River don’t be surprised to hear her squeal, “Oh, look! There’s an osprey!” and she’ll talk about what it was like being out on the River with biologists during FOLAR’s first fish study. She knows that a swimmable, fishable, boatable Los Angeles River is possible, just ask her about what the time she fell out of a kayak in the Glendale Narrows.

Ivana was born and raised in Southern California, with a brief stint at a young age in her family’s native northern Mexico. Both regions inspired an early love for all things nature – from the wildlands just a stone’s throw away from either city, to the urban wildlife that calls Los Angeles home. Inspired by this love, she graduated from USC with a degree in environmental studies and was part of a pioneering team that helped launch the Audubon Center at Debs Park, an environmental education center in Northeast LA. Today, you’ll find Ivana connecting donors to FOLAR’s mission, often on a kayak, immersing them in the River’s beauty.

Chris is an LA native who grew up in near the River and developed a passionate love for all things Los Angeles. He’s dedicated to public service and has worked with organizations from his old high school’s Science Bowl Team to the American Red Cross. At FOLAR you can find Chris working to keep the community connected to FOLAR’s work. Whether it’s working up with the Policy team to activate the community in the fight for river restoration or putting out the call to gather for the next big LA River event, Chris in the middle of the action.

Native Angelino, Johanna has lived her entire life in her beloved birth city. In the midst of earning her Psychology degree from Antioch University, Johanna took a course on the Los Angeles River. The course exposed Johanna to a bounty of interesting facets of The River and more importantly, the effects The River has on the lives of Angelenos. She fell head over heels in love with the Los Angeles River and her commitment to the LA River was born. The Frog Spot was inspired and born of Johanna’s desire to marry the Los Angeles River with the community through art, music, local history and native culture. Johanna has also curated Fandango since conception and been on all efforts to grow the Great LA River CleanUp: La Gran Limpieza.

As Policy & Advocacy Manager, Stephen helps support and lead the execution of FOLAR’s policy and advocacy initiatives. As a native Angeleno, Stephen places special emphasis on the inclusion of underserved communities in environmental discourse. For the past 5 years he’s worked throughout LA County building watershed literacy, inspiring local stewardship and empowering community voices of all ages in local watershed planning efforts. He’s pretty stubborn about the connection between social and environmental health, the importance of acknowledging injustice, and the strength of optimism and hope. When he’s not being dramatic, you can find him riding his bike, exploring the city or some hidden park. He’s also a sucker for board games, maps, street art, food, and good company.

For the past decade, Mr. Bowling has been working at FOLAR on various River projects. From managing fish studies to creating the First-Ever catch and release fishing derby on the L.A. River to presentations on river history, you can really ask him anything. William provides support for educators from K to College by bringing a detailed river curriculum followed by a visit from FOLAR’s mobile museum, the Los Angeles River Rover to schools and community events within the watershed. You may also find him hosting several River tours each year; in person and in Virtual Reality.

Galina grew up in Northern California, and developed a reverence for nature among our great state’s rivers, lakes, and ancient forests. Prior to joining FOLAR, Galina worked for the Downtown Women’s Center in LA’s Skid Row. She joined DWC’s development team in the throes of a 35m dollar capital campaign which ultimately provided 71 new units of permanent supportive housing for homeless women. Over three years at DWC, she recognized her passion for nonprofit development and its essential power to enact positive change. She loves the tranquility the River brings amidst the bustling city, and enjoys bird watching along its banks. You can find Galina writing grant proposals and working with donors, in service to a shared vision of a healthy, dignified LA River for generations to come.

Alexandra is an administrative assistant for Friends of the LA River. She was one of many Angelenos who didn’t know a Los Angeles River existed, but as soon as she was introduced she fell in love with the beauty of it. Inspired by all of the dedication and passion from Friends of the LA River, she made her way into the family and now proudly works hand in hand with founder Lewis MacAdams and the rest of the FOLAR to continue the artwork that Lewis began.

Liliana has always had a passion for working with the environment, from teaching SCUBA diving to identifying microalgae in a landfill. When Liliana returned home to Los Angeles, after completing her Masters in Europe, her eyes were widened by the lack of access her fellow Angelenos had to nature. Working as the Programs and Policy Manager at FoLAR, she is given the opportunity to connect her community with the environment and provide a voice for the River. Liliana is excited to be doing work around the River, as it has infinite opportunities to promote community engagement and bring all Angelenos closer to nature.

Lewis MacAdams is an American poet, journalist, political activist and journalist. In 1986, MacAdams created Friends of the LA River, a “forty-year artwork” to bring the Los Angeles River back to life. In the years since, FOLAR has become the River’s most important and influential advocate, with an E- newsletter and social media that reaches over 60,000 people. Among FOLAR’s many projects are “La Gran Limpieza,” the Great Los Angeles River Clean-Up, the largest urban river clean-up in the United States; a summer length riverfront cabaret, The Frog Spot, that has welcomed nearly 40,000 visitors; a collaboration with the Aquarium of the Pacific, a K-12 “River School” outdoor education curriculum; the “Los Angeles River Rover,” a 38-foot recreational vehicle designed as a mobile classroom; and the first reports on legal access to fishing on the L.A.River. His pamphlet, D-Town Visions: Building A City The River Can Be Proud Of, was published at the beginning of 2008 by The Natural Resources Defense Council. Friends of the LA River was able to organize and lead multi-ethnic, multi-racial, multi-class coalitions that stopped major riverfront industrial developments leading to the creation of a pair of State parks in the Cornfield and the Taylor railroad yards.

He is currently on the Board of Directors of Friends of the LA River and centers his time on his book Poetry and Politics, a clear depiction of his lifelong work.

Charles has spent his career as an environmental and natural resources attorney, as a manager of businesses in those fields, and in the development of nonprofit organizations. Coming to Los Angeles and a neighborhood abutting the Los Angeles River in 1980, he became interested in the river and its potential while exploring and using adjacent roadways for biking and hiking. Before moving to Los Angeles, his career was spent in public service in Washington D.C., holding policy positions in the Department of the Interior and the Council on Environmental Quality, and working with nonprofit organizations. His work since has spanned businesses in environmental and alternative and conventional energy technology and energy conservation. He graduated from Cornell University Law School in 1970, holds a degree in international relations from the University of Colorado, and served as a U.S. Navy officer.

After graduating in 2015, Lily immediately moved to NY to try her hand at working in television, but soon found the city and the TV industry wasn’t where her heart lied. She missed Los Angeles’ vastness, the easy access to nature, and was looking for work more involved with her community. With that realization, Lily moved back to LA to soon begin her internship at the educational nonprofit, 826LA, where she spent a year teaching creative writing and tutoring students ages 6-18. Lily has long loved California’s bountiful nature and is happy to now be apart of an organization that advocates for our city’s largest natural landmark. In her spare time, Lily enjoys buying too many books at Skylight Bookstore, hiking local trails, and heading to the Sierra Nevada to camp and be in nature.

“What river?!?!” This was Zoe’s response when, in a writing class in her junior year of college, her professor announced that the Los Angeles River would be the focus of much of the class. Born and raised 30 miles east of LA, Zoe was dumbfounded to learn that LA was home to a river that she had never known about. Intrigued, Zoe set out to learn more about the River, making it the subject of her senior thesis. She became passionate about the River—fascinated by its rich ecological history, saddened by its unfortunate channelization, but hopeful and excited for what the future holds for its revitalization. After graduating in May 2016, Zoe decided to pursue her River passions and sought out an internship with FoLAR. After interning in the Development Department for 6 months, Zoe joined the FoLAR team as the Development Assistant and later transitioned to the Operations Department. She loves FoLAR and is incredibly grateful to be a part of this organization, where she gets to experience what goes on behind the scenes to re-connect Angelenos to their River.

Mareshah “MJ” Jackson has built a career expanding community networks with local nonprofits through outreach and public activation. She’s passionate about the connection between community wellbeing and access to nature, physical recreation, and open community space. When she’s not cultivating the relationships that enable FoLAR to increase every Angeleno’s access to green space, she’s looking for ways to stay active. You can find MJ practicing samba, training for long-distance runs, and learning about LA by taking Metro to new destinations.

Mike understands the intersection of nature and cities from an unusual perspective – he grew up on a farm in rural Missouri with nature stretching for countless miles in every direction, but since graduating from university he has lived either years or months in Los Angeles, Chicago, New York City, Seattle, Moscow, Sydney and Florence. Seeking out the best examples of overlapping nature and urban landscape has been a pleasure for many years now.

Living in Los Feliz with his wife, a native Angelina, three young sons and giant Bernese Mountain Dog, on weekends he can be found hiking Griffith Park with his family, chasing his kids in the surf, or showing off his backyard grilling skills for friends. He has also been known to drag his family down to the LA River for an impromptu cleanup and discussion about the importance of community service.

Mike has spent his career in finance – in his role as Senior Vice President for Cascadia Capital, he leads the aerospace and defense investment banking practice for the firm, advising executives and business owners in mergers and acquisitions. Mike holds a masters in business from Stanford University where he was a Sloan Fellow and a bachelors in finance from the University of Missouri.

Reymundo, or Rey, grew up right by the Los Angeles River in Compton, California. He attended the University of California – Irvine where he experienced a culture clash that inspired him to find a way to give back to communities like his hometown. Prior to working at FoLAR, he worked throughout Los Angeles in marketing and education based jobs that grew his love for the greater Los Angeles Area. His work with FoLAR began at The Frog Spot where he got to see the river be lit up in the morning by the sun and framed beautifully by the moon at night. This experience made Rey want to join in the work towards a more inclusive and natural river for his beloved city of Los Angeles.
