Rim of the Valley Corridor Preservation Act

(Opening excerpt from a press release on Senator Adam Schiff’s website. Bold highlights are our own)

Washington, D.C. — Today, U.S. Senator Adam Schiff (D-Calif.) and U.S. Representative Laura Friedman (D-Calif.-30) introduced the bicameral reintroduction of the Rim of the Valley Corridor Preservation Act, landmark legislation that would protect some of the last wild and open spaces in the Los Angeles area and allow the National Park Service (NPS) to work with local communities to better protect natural resources and improve access to nature. This bill would add over 118,000 acres to the Santa Monica Mountains National Recreation Area (SMMNRA) and is based on an NPS study that was reported to Congress in 2016.  

The Rim of the Valley stretches from the Simi Hills and Santa Susanas to the Verdugos and the San Gabriel Mountains, making a “green belt” that encircles the San Fernando, La Crescenta, Santa Clarita, Simi, and Conejo Valleys.

UCLA researchers conducting visitor counts, need volunteers to help

A team of student researchers from the Institute of the Environment and Sustainability (IoES) at UCLA is conducting visitor counts and surveys at trails in the Santa Monica Mountains this spring.

Their work is a collaboration between UCLA IoES, the Anthony Pritzker Family Foundation, the Mountains Recreation and Conservation Authority (MRCA), and the Grateful Bench Project.

The visitor counts will provide a better understanding of trail use since the last SMMNRA trail survey conducted in 2018. The data collected will help the Grateful Bench Project improve visitor access to trails, inform their efforts to educate visitors about the trails, and deepen visitor appreciation of natural resources in the park.

The UCLA IoES team is recruiting volunteers to help with the visitor counts.

Volunteers will be stationed at one of 20 trailheads (see map below) and will count visitors for four-hour shifts on Saturdays, April 26th or May 3rd.

If you would be interested in volunteering with this team of UCLA researchers to perform visitor counts at certain Santa Monica Mountains trailheads, please RSVP using their Volunteer Registration Form

Trailheads where visitor counts will be conducted on Saturday, April 26th and May 3rd, 2025.

In addition, the team will be installing fliers on newly installed benches with QR codes linking to a short visitor survey. These surveys will gather data on trail usage and visitor experience, helping Grateful Bench design outreach and educational material for park visitors.

The goal is to eventually install permanent QR codes on benches that will bring visitors to location-specific information about park natural history and ecology. While benches throughout the park provide a place for hikers to rest and enjoy the mountain scenery, equipping them with these electronic “plaques” transforms the otherwise simple amenities into educational tools. Their goal is to offer visitors a wealth of information about the habitats and ecosystems in front of them, fostering a deeper appreciation for the nature that surrounds them.

Trail Days 2025: that’s a wrap!

In the post-dawn chill, the caravan grew, car after car, along the unassuming dirt strip leading to a service road. With a beckon, it began to move, this serpentine line of vehicles full of people eager to join those already camped under soft oak shade in the beautiful, rain-greened depths of Point Mugu State Park…

Welcome to Santa Monica Mountains Trail Days 2025! For those who participated in this year’s event, thank you so much! We hope that you had as much fun as we did.

By all accounts it was a huge turnout. Cars packed what spaces tents didn’t. At Danielson Ranch, people caffeinated, breakfasted and mingled across many different groups and organizations, including California State Parks, National Park Service, Santa Monica Mountains Trails Council (SMMTC), Concerned Off Road Bicyclists Association (CORBA) and your trusty Sierra Club Santa Monica Mountains Task Force (SMMTF).

Sierra Club crew leaders oversaw about 60 volunteers in our group alone on Saturday, who, after a brief orientation from our own Bill Vanderberg, trekked a mile further into the brush to work on the Coyote Trail.

Others took their McLeods, loppers and saws to trails such as the Upper Sycamore Canyon, Two Foxes, Blue Canyon and more.

After a thoroughly gratifying, sweat-beaded day of trail work, everyone reconvened at camp for some much-deserved refreshments, appetites further whetted by the BBQ smoke twisting through the air.

Sponsors of Trail Days 2025

Now forty-plus years old, Trail Days has been integral in elevating awareness of — and engagement with — the welfare of the Santa Monica Mountains. It happens every April.

State Parks interview on the Palisades Fire, April 8th

Join Parks California for an Instagram Live interview on Tuesday, April 8th, at noon, and an in-depth look at resilience in the aftermath of the Palisades Fire.

The chat will feature colleagues from the Wildfire and Forest Resilience program, and CA State Parks staff members including Senior Environmental Scientists Lisa Andreano and Brooke Sheridan, and Forester I Azalie (Oz) Welsh.

These team members had to tap into their training quickly as they faced the destructive Palisades Fire in January. We’ll hear how they took action to help firefighters minimize the effects of fire on archaeological sites, rare plants, endangered species, tribal assets and wilderness areas.

Santa Monica Mountains Trail Days, April 4-6

Join our annual celebration of local trails and parkland!

There’s an important task for everyone at Santa Monica Mountains Trail Days, from seasoned trail builders to first-time volunteers, as well as age-appropriate activities for children.

Registration is required. Sign up here.

There will be trail projects on Saturday and Sunday, a complimentary BBQ dinner on Saturday evening, a jumbo thank-you gift drawing on both days (generously sponsored by our organizers and community members), and much more.

Come out for a day to help clean up trails — or perhaps stay for the weekend, and enjoy a night or two of free camping at Danielson Group Campground.

Organizing partners are the Santa Monica Mountains Trails Council, the Concerned Off-Road Bicyclists Association, and ourselves, with support from California State Parks and the National Park Service.

We hope to see you there!

Trail work | Saturday, March 22nd, 2025

This Saturday, 3/22/2025, our trail crew will be working on TWO trails on the north side of Topanga SP (via Reseda Blvd). Registration is required.

As well as making repairs to the fire-damaged Gizmo Trail, we’ll carry out routine brush maintenance on the nearby Rita Walters Trail, which is closer to the trailhead and outside the burn perimeter.

We will split into several work parties, jointly-led by Sierra Club and Santa Monica Mountains Trails Council crew leaders. No experience is necessary to participate in trail work with us. Volunteers will receive one-to-one training and support from our seasoned crew leaders. We also provide the tools.

Below, you can read about each project/site: the nature of the work, tools we might be using, what to bring, etc. There will be tasks suited to most levels of physical ability, so whether you’d prefer lighter tasks like clipping overgrown vegetation, or working with picks, shovels and big rocks, there will be plenty for everyone to do!

Spaces are limited. This will be our first trail repair event following the Palisades Fire, and many more opportunities to volunteer will be posted in the coming weeks.

If you have any questions, please email the Volunteer Coordinator, or reach out to any of the leaders listed below.

Event schedule

We will meet at the Top of Reseda at 8:30 am. The park is currently closed to the public and a security guard will be posted at the entrance gate, but they are expecting us. Watch out for the stop sign camera near the top of the hill to avoid getting a ticket.

On arrival, please visit the sign-in station first!

Participants will sign two liability waivers: one for Sierra Club and the other for CA State Parks. Then we will verify your preferences for tools/tasks, and assign you a work site and crew leader. There will be hot coffee and snacks when you get there, and the bathrooms at our meeting location should be open.

Please stay close by, as there will be some very important announcements made before we move out to the work sites in groups.

By 12:30 pm, all crews will have wrapped up work and returned to the meeting spot, where ice-cold refreshments will be waiting for us.

About the work

Rita Walters Trail:

The better choice if you would prefer lighter tasks, access to the amenities, or want to stay out of the burn area. This trail begins right at our meeting spot, and is just 0.3 miles long with a very gentle climb, making for a pleasant bypass to the steep fire road that leads into the park.

Light to moderate work. The predominant task will be brushing: ie. removal of overgrown vegetation from the travel way. We’ll also clear any accumulated silt and vegetation from drains, and remove plant debris that was pushed onto the trail from the roadway above during the fire response. Some commonly used tools are loppers, shears, small saws, McLeod hoes, and rakes.

Gizmo Trail:

This is specifically post-fire restoration work. Moderate to heavy labor. Our goal is to reestablish the trail’s original construction standards. The absence of vegetation gives us a rare opportunity to fix known problem spots and improve drainage. Tools used might include McLeods, picks, shovels, buckets, rock bars, rock slings.

The EPA’s Toxic Pileup

Many concerns have been voiced about the news of the EPA setting up a three-month “hazardous waste” site to consolidate and manage the materials from the Palisades Fire. In fact, there was a protest about it: yesterday’s March to Save the Sea, which took place on the Santa Monica Pier. The RCDSMM, or, the Resource Conservation District of the Santa Monica Mountains, issued a statement which, in part, reads:

As a local agency facilitating resource protection and public connections with the environment in the Santa Monica Mountains, the RCDSMM has concerns regarding the chosen site and would have preferred a different location. Critical habitat for the endangered steelhead trout and tidewater goby is located directly adjacent to the motel site within Topanga Creek and Lagoon and is at risk if contaminated materials are inadvertently spread into these areas. Adjacent beaches and near-shore areas located just downstream could also be harmed, degrading recreation uses and unique fish and wildlife habitats.

Located at the mouth of Topanga Canyon near Topanga Lagoon, the site is one of ecological sensitivity and cultural significance. The lagoon itself is slated to undergo restoration in the near future.

Debate presses on, with organizations such as Heal the Bay decrying the project, arguing they were not consulted, and that such toxic materials, left exposed, could well seep into the soil and the ocean. Others counter that the waste pile had to go somewhere, and any decision would necessarily be controversial. See the bullet points of Heal the Bay’s meeting with the EPA. Somewhat unsettlingly, the EPA’s own FAQ for this issue returns a “Cannot Find The Page You’re Looking For.”

The EPA has also announced it will use the parking lot of Will Rogers State Beach as a staging area for removal of fire debris. Councilwoman Traci Park is against this proposal.

U.S. Army Corps of Engineers Expands Hazardous Tree Marking System, Clarifies Waiver Process

PRESS RELEASE
U.S. Army Corps of Engineers
March 6, 2025

In response to community feedback and a comprehensive review of hazardous tree removal procedures, the U.S. Army Corps of Engineers (USACE) has implemented updates to its tree marking system and clarified details regarding the newly available hazardous tree removal waiver.

To enhance transparency and improve processes, USACE has added two new color markings in addition to the existing blue dot, which signifies a tree that has been assessed and determined to be hazardous.

Blue Dot – Trees marked with a blue dot at the base and a barcode have been determined to be hazardous and are scheduled for removal.

Yellow Dot with Yellow Ribbon – Trees where a property owner has submitted a hazardous tree removal waiver will be marked with a yellow dot at the base and a yellow ribbon wrapped around the tree. The barcode will be removed, and this update will be cataloged in the contractor’s system to ensure the tree remains in place.

Brown Dot – If a tree is reassessed and determined to be non-hazardous by a higher-level ISA-certified arborist, it will be marked with a brown dot over the existing blue dot. The barcode will be removed, and this update will be recorded in the contractor’s tracking system, confirming the tree will not be removed.

The Waiver of Hazardous Tree Removal form is linked here and also available at recovery.lacounty.gov. Owners are encouraged to express their intent to waive tree removal during the 72-hour and 24-hour notification calls.

In response to community concerns, USACE has amended its waiver submission process. Property owners may now submit the Waiver of Hazardous Tree Removal via email or to the contractor during the 360-degree walkthrough, which is the last step before debris removal operations begin. Completed forms must be emailed to Eatoncallcenter@ecc.net for Altadena properties or Palisadescallcenter@ecc.net for Palisades properties. USACE contractors are making every effort to accept supporting information in a variety of formats—including photos, emails, and other documentation—to meet property owners’ requests and properly record their decisions.

“We are committed to listening to the community and improving our processes,” said U.S. Army Col. Eric Swenson, commander of the USACE Los Angeles Wildfires Recovery Field Office. “Our goal is to provide a clear, fair, and transparent system that respects property owners’ choices while prioritizing safety. The new tree markings and flexibility in how information is received reflect our commitment to making this process as accessible and efficient as possible.”

To expedite the waiver process, property owners are encouraged to assess the trees on their property as early as possible. This will ensure they have the necessary information ready when contacted by the USACE contractor for their scheduled walkthrough.

Important Reminder: Do Not Self-Mark Trees Community members have been self-marking trees in an effort to preserve them. USACE urges members of the community not to paint trees. Some paints contain toxic substances that can harm trees and the surrounding environment. Property owners should follow the official waiver process to document their decision to retain a tree.

USACE is committed to transparency, continuous improvement, and supporting the recovery of wildfire-affected communities. By listening to community concerns and optimizing our processes, we are working to ensure that property owners have clear information and meaningful choices as they navigate the recovery process.

For more information and updates on the wildfire debris removal effort, please visit recovery.lacounty.gov.

Next Meeting: May 13th, 2025

Thank you to everyone who attended the March meeting. For those who Zoomed in, we apologize for the difficulties with the audio. Rest assured, we’re in the process of upgrading our tech, rendering such issues a thing of the past come the next meeting on May 13th. (We meet every 2 months, on the first Tuesday—occasionally the second Tuesday, or skipping a month, if needed for a quorum).

We’re considering the need for a Zoom meeting facilitator. If this happens to be your area of expertise, let us know!

Also: several people had not received the Zoom link, which was an oversight. Please join the mailing list and choose “Task Force meetings” under Mail Preferences. To update your mailing list subscription at any time, simply sign up again using the same email address, and your profile will update automatically.

While we don’t keep recordings, we’re working on a series of updates for the news blog which will cover all the salient points from Tuesday’s meeting, the most important of which will also be emailed to you as a mailing list subscriber. Thanks for staying engaged!

Since this recent past meeting, we’ve been giving a lot of thought to one particular question which came up: What are the bottlenecks? The biggest problem seems to be getting information out efficiently, and providing a clear resource for information such as when the parks and trails will be reopened, when and how people will be able volunteer in the restoration effort, fast-developing news such as the Topanga toxic waste site, the health and safety of the affected areas and other concerns.

Right now, what we need most urgently is to expand our Communications Team. As the Task Force continues its multi-pronged effort to protect and maintain the Santa Monica Mountains, across several domains, we need volunteers to take on a “pet” issue and keep track of its progress, attend key meetings elsewhere, write about it for the blog, report on it at our meetings, help coordinate action campaigns, and so on. Interested? Email us!

We’ve always been a small group of 8 or 10 people, discussing a small agenda. Carrying the torch. (Our predecessors were instrumental in the decades-long effort to establish a Santa Monica Mountains National Recreation Area.) But it looks like we’re encountering a significant growth in engagement. Our founders, Ron and Mary Ann Webster, would be proud.

We’ll be sharing many more updates over the coming days and weeks, especially details for March 15th and other upcoming trail work events. Feel free to contact us with any specific questions that come up.

Thank you for your interest! We look forward to meeting you!
