BREAKING GROUND AT JEFFERSON TEST PLOT

FOLLOW ALONG: Maintenance journal

Over 100 plants were planted this past month at the Jefferson Test Plot, a former oil drilling site between the Adams-Normandie and Exposition Park neighborhoods. Thanks to the efforts of Redeemer Community Partnership (RCP), the RCP Youth Fellows, Los Angeles Neighborhood Land (LANLT), Theodore Payne Foundation (TPF) and dedicated volunteers, we were able to gather and plant part of this block for the first time in over 60 years.

The following log is a history and reflection written by the cohort of youth fellows who were instrumental in starting and stewarding this plot.

Redeemer Community Partnership, Los Angeles Neighborhood Land Trust, and the Test Plot Youth Fellows

Redeemer Community Partnership (RCP) is a non-profit supporting children and young adults in South Los Angeles by creating a network of programs that advocate for public health and safety, environmental justice, and career development. RCP and Test Plot have created a cohort of 11 local high school students, youth fellows, to steward the Jefferson Test Plot. The youth fellows meet weekly at Greenhouse South LA, a community gathering space in Exposition Park that also promotes sustainable home electrification and youth workforce development. South Los Angeles is an overlooked community where many youth feel they don't have a voice, and this space allows them to express themselves creatively and explore different career paths.

LANLT and RCP partnered to purchase the site with a $10 million state budget allocation secured by Assemblymember Reggie Jones-Sawyer. Together,  RCP and LANLT steward the site, now known as the Jefferson Park and Affordable Housing Project.

LANLT is currently in the process of remediating underground pollution (though the site is currently safe to gather and work on) and finalizing the design of the future park and housing. Test Plot was brought on in this interim period to create a temporary native plant garden that would inform the final plant palette while also giving the community a chance to engage and build a relationship with native plants and the site itself.

The Jefferson Test Plot is generously supported by EJ Ready, a partnership by Liberty Hill Foundation and Resources Legacy Fund.





Jefferson Drill Site History (Slideshow)






2026 — Where we are now

Now that the Jefferson Drill site is fully closed, as of January 2026 RCP and LA Neighborhood Land Trust have been meeting at the Jefferson site regularly with community members to discuss remediation and the futre park and housing design concepts. In November of 2025, Test Plot was brought on to lead a temporary restoration garden in the interim years before the final housing and park project can be built.

Process 

In January of 2026, the youth fellows met on site to brainstorm and sketch possible layouts. The initial designs consisted of symbolic images such as flowers, spirals, suns, bugs, smiley faces, and more. We wanted to make the plot an icon that people looking down from their apartments and second stories could recognize. We wanted to incorporate features like a central gathering area and log stumps that would give people to walk, rest in the shade, or run and play. This test plot will be accessible to all ages.




We ultimately decided to use the shape of the flower as it symbolized turning something negative and harmful, into something beautiful for our community. For the location, we wanted the plot to be highly visible to the community, where people could walk by and see all of the beautiful native plants. This area was also teeming with lush spontaneous vegetation, mostly mallow and Stork’s bill, which was a good sign that things could grow in our future garden.

We first cleared the space by weeding and picking out rocks. Jen led us through a design exercise, where we calculated the length of our steps as a way to figure out an appropriate scale of the plot. Using rope and flags, we walked out each petal, making sure they were large enough to work and plant in.





Before we planted, we sampled the soil and learned of its high pH and low nitrogen and organic matter content. Much of the soil appears to be backfill, full of rocks, concrete, bricks, and asphalt rubble, remnants of its industrial use and demolition, potentially contributing to its high 8.0 pH.

The soil was highly compacted and difficult to dig by hand. Facing this challenge we had to use water to soften it up for digging, weeding, and installing the fence posts. Because the soil is so compacted, we drilled several vertical mulch holes to help water infiltrate deeper into the site. Plants were organized around each of these holes. With time, as these plants grow, the soil will soften and reach proper nutrient levels.



Plant Selection

With consultation from the Theodore Payne Foundation, we selected a variety of California native grasses and coast sage scrub plants that would be suitable for such a tough site. We tried to prioritize pioneer species like Isocoma menziesii (goldenbush), Artemesia californica (california sagebrush), Encelia californica (bush sunflower), and alkaline tolerant species like Distichlis spicata (salt grass), and Atriplex canescens (saltbush). We also included flowering plants like Diplacus auranticus (sticky monkey flower), Epilobium canum (California fuschia), and Helianthus annuus (common sunflower) to add visual interest to the plot.

The five petals of our flower are broken into two grassland plots, two coastal sage scrub plots, and one desert plot.


With soil tests, plant palettes, and layouts done, we were eager to finally break ground at the plot. We hosted our first community planting day on February 8th with over 40 neighbors and supporters. It was definitely a party with lots of effort and good vibes.  But breaking ground proved harder than we had hoped. Despite the weeks of rain in December thorugh the new year, the ground had quickly returned to its dry, stubborn, impenetrable state. With shovels alone, no one could get past a few inches. By the end of our first planting day, only a handful of plants made it into the ground. Thank you to the volunteers that dug the holes!

Learning from this first session, we diligently prepped the site ahead of our next planting day, our last opportunity to plant this season. We weeded, installed fences, and saturated the ground with water, allowing us to focus all our energy on mulching and planting.

As our March 14th event grew closer, the forecasted temperature continued to rise. We moved our event to the early evening to dodge this unseasonable, unwelcome heat wave. Thankfully, an eager crowd of volunteers returned to help plant the remaining plants. As the sun set, with auger in hand, we were able to get over 100 plants and several vertical mulch holes in the ground. Craig and Erik from the Theodore Payne foundation graciously taught volunteers how to plant and water. Esteban and Mireya from the LANLT installed a shed for tools and hoses. In the end, we planted 3 of the 5 petals with grassland and coastal sage scrub species. We were also happy to see that the handful of plants that we planted in February were not only alive, but thriving. 




Jefferson test plot is our first properly urban site, not situated in or next to an extensive park system. Yet despite the lack of recreational foot traffic, folks have continually stopped, stared, and struck up conversations with us on our workdays. There is an encouraging and clear interest for people to work and contribute to the rehabilitation of this abandoned lot. It’s a promising sign, especially since the road ahead will be tough.

That planting day came late in the season. The days following the event have been brutally hot and dry, not ideal for establishing these plants. From now until the fall, we plan to water weekly, to give the babies a fighting chance. And there is still more to be done, mulching, adding signage, wayfinding, and other features to enhance the garden. The best is yet to come at the Jefferson Test Plot!



GETTING STARTED, SIMI VALLEY TEST PLOT

By Isaac Trejo
Simi Valley Test Plot Lead
DATE: March 08, 2026
TEMP/WEATHER: beautifully sunny, a bit windy
IG @testplot_simi
Maintenance journal

The Simi Valley Test Plot lies at the base of the foothills between Rocky Peak and Chumash Park. Started by local residents concerned about the fire resiliency of their surroundings, the plot collaborates with MRCA and the Rancho Simi Recreation and Park District to address the current, invasive and highly flammable fuel-type and investigate the performance of locally adapted, slower to burn native species.

The project is situated at the intersection of a rich scrub of predominantly Bush Sunflower, California Sagebrush, and Chamise and a primarily invasive grassland featuring mustard, oat, and brome dotted with a mix of native wildflowers such as Blue Dicks, Lupine, Fiddleneck, and Tarweed. The plot mimics the native vegetation found in the surrounding area by creating a combination of scrub and grassland increasing the biodiversity, beauty, and resiliency of the landscape.


VOLUNTEERS:  A great turnout of volunteers from both LA and Simi, the donuts were a big hit.

PLOT + CONTROL PLOT: The goal was to plant and water about 87.5 plants in Plot 1. We planted 85! And would not try to plant a whole lot more in Plot 1. We had such a great turnout some volunteers were able to completely establish the Control Plot. I noticed two plots create quite the visual impact and show how much progress made together with just a little bit of time (and calories, as one said).

Fences were built, water was administered.

PLANTS: Some of the perennial shrubs to be planted looked a little sad, largely due to the wind. Pretty amazing how quickly they dry out in their little pots.

Overall we planted ~85 plants and 11 different species in our little 20’-wide blob, with about half of them being purple needle grass, the historic vegetation series found on the site. The purple needle grass was planted in groups of 5-6 somewhat per Bert Wilson’s recommendation and infilled with some of the scrub species that mirror the hills nearby, a way of hedging our bets. I personally have a lot of faith that there is a wealth of native species waiting to pop up, whether by seed or bulb (or maybe even scat).

WEEDS: The Control Plot is another 20’-wide blob that has been weeded and nothing else. As opposed to the “pull-and-drop” approach of weed management on Plot 1 (where annual weeds were pulled and dropped to create a thatchy mulch), this Control Plot will have none. The Control Plot will also not be watered (though my over zealous self gave it a spray down, I will show restraint in the future). Again, my intuition says that there will be lots of natives popping up in this one as well.

Weed management will be tricky but key, in establishing our hybrid little grassland. I am thankful that the weeds on site are easily pullable (largely mustard, oat, and brome) and nothing tedious like oxalis or nutgrass. Work for the majority of the year will just be to weed.

WILDLIFE: While the site has LOTS of wildlife, being located right on the WUI Interface (residents regularly see coyotes, quail, hummingbirds, owls, deer, and even mountain lions) there was not much to be seen this morning. One volunteer reported seeing a tiny mouse run for cover while weeding the Control Plot, so insofar we are at a net loss for wildlife habitat :/

STEWARDSHIP: We are still looking for local and long-term stewards aside from myself. The site receives lots of foot traffic and loads of recreation and is in and of itself great promotion.

TO DO: Lots to do. I want there to be a large focus on how the project faces the public, providing appropriate signage and communication about the project to anyone who walks by. The site gets so much attention from everyone who passes by it, I never realized how popular the park and trails around here were.

While there is not much more planting to be done (aside from replacing any losses) I would like to have programs that engage people with the site, a plant walk comes to mind but am open to ideas!








RAINY DAYS AND RECOVERY

Rainbow Canyon Test Plot
By Andre Grospe
Test Plot Landscape Designer
Date: Jan 15 2026

If you returned to Rainbow Canyon after these winter storms you may have noticed some changes. There are several new washes of sand, new patches of litter and debris, extra ruts in the ground, traces that something powerful came through. It can feel like forensics, seeing what’s left after a big rain and deducing what might have caused these changes. They are subtle reminders of how dynamic Rainbow Canyon can be.


Obviously this is not a unique event and heavy rains can be more a nuisance and hazard than a wondrous experience, especially to those living downstream. Previous documentation clearly shows more severe debris flows than I had seen. But these gentle and moderate rains gave me a chance to document and appreciate the nuances of a stream and what they offered to the overall experience of the lower canyon (as opposed to just focusing on the awesome and terrifying high flow events).  What kind of aesthetic experiences do we gain if we implemented best management practices (BMPs) and other channel modifications?



I would suspect that most who wander in and out of Rainbow Canyon see its heavily eroded channel as an ugly scar, an obstacle to jump across, or a problem to be solved. While it is these things, it is also the product and home of an ephemeral stream that has shaped the way we design and work with the lower canyon plots.The entrance trails into the lower canyon are defined and continually eroded by stream diversions and have stymied and frustrated our mulch truck drivers and resulted in more than one twisted ankle. During heavy rain events sediment, logs, and other debris wash out directly onto Ave 45. Suffice it to say, this stream is a blessing and a curse and currently, with the help of a grant from the Water Foundation and Rose Foundation, we have been trying to understand and mitigate these problems. These storms have been an amazing opportunity to rigorously document these stream dynamics, testing out new methods and technologies along the way.


During the November 15th rain event, we ended up getting 1.65” of rain.2  When I arrived to document, the canyon wasn’t the raging river I had expected, with no water actively running through the channel. Not too long after I had arrived however, I heard a light gurgling sound and saw the fresh grasses growing in the channel begin to fold over. The smell of fresh soil filled the air. Excitedly, I was able to capture the first flush through the canyon. The water was a dark, opaque brown (think hot chocolate) but was relatively relaxed, tumbling over the roots and rocks. I followed the water out to the entrance and watched it pour over the stone steps you pass when you enter the canyon, creating a lovely set of waterfalls before emptying out onto the street.




Elsewhere in the site, small springs and pipes burbled out water. I wondered if these were some of the bits of infrastructure we had found digging through city datasets or just gopher holes being flushed out. Either way, they were cute curiosities closer to the entrance of the canyon.



I left before the rains got heavy, but when I returned the following week, more changes than I had witnessed had obviously occurred. Over the course of the storm, water had carved a third diversion whose path left a trail of bent grass and new sand. This was a particularly useful and reassuring confirmation of our numerical modelling, which, while rough, had similar flow patterns during lower and higher flow events.


The water had also left an array of beautifully complex depositional forms, some sinuous and fan-like, showing where water crossed and flowed around different obstacles. Others were soft, dramatic, pillowy ripples, particularly in the stone steps at the entrance, where the waterfalls created stirring eddies that caused sediment to slowly accrete in the pool. Some parts of the channel seemed to fill up with sand.



The next rain event of 2025, on Christmas Eve, was a much larger one, almost 2.6 inches in the area. Following the LA County Hydrology Manual, that would make this an almost exact 2-year rain event in the Mount Washington area.3

With November’s fieldwork in the back of my mind, I returned with a better camera (a mistake) and a focus to try to capture the nuances of the flow. I had a goal to connect the flow of water to some of the depositional forms I saw in November. I also wanted to try a new monitoring technique, using an iPad’s lidar scanner and Polycam to stitch together a plan of the flow path which worked well even despite some of the tall grass and standing waves confusing the software a bit.

 
 
Christmas Eve’s storms were intense and unpredictable. The channel was nearly full to the brim with water whipping around rocks and logs. The stone steps at the entrance were overflowing, spilling out onto either side of its walls. Large flashes of water came in pulses, signaled first by sound, then by color as the stream darkened with new sediment.

When I returned after the storms, on our first workday of 2026, the canyon had again been noticeably rearranged. A tire lodged itself in front of the riparian plot, causing an extreme buildup of sediment, creating a new sand bridge to cross the channel. But the tire had also diverted water onto the trail between the riparian and fire buffer plots, further degrading it.


Upstream of the riparian plot, the channel continued to transform into a gulley with a defined headcut that continues to erode and deepen the channel. Left unchecked, this section will continue to deepen and retreat upstream.



Further downstream past the riparian plot was a new deposit of sand. Logs and debris seemed to have blocked the typical flow path, redirecting the water further away from the trails. Formerly this tributary would only flow during higher storm events, but with the current debris blocking the way this could be the start of a new flow direction. It will be something to keep an eye on during the next rains. How will water interact with this loose material? It will be an unpredictable and exciting experiment. Will we remove the newfound debris or leave it in place to train a new flow path? To be determined.


In the meantime, volunteers at the 1/10 event, mostly returning visitors, got right back to work mulching and weeding the switchback plots. Alex and Isaac installed logs and drainage to reinforce the switchbacks. Alex sprinkled wildflower seed in trail spoil. The elderberries are sprouting new leaves and flowers are beginning to bloom. I look forward to tracking their progress through the spring. After our work session finished, a family came down to the new sand wash and started to make sand castles. The next few sessions will focus on recovering and repairing from these storms and preparing for the next, whether they be next month or next year.

Storm flows in Rainbow Canyon are no joke with flash floods being fast, unpredictable, and dangerous. But in a moderate rain event canyons like Rainbow Canyon activate in surprising ways. I hope some of you get a chance to swing through and maybe even linger (the dense branches of the elderberry and palm tree make good site umbrellas). Open spaces like these give us Angelinos a way to observe rain and flowing water in a different way, not just rushing past curbs and concrete lined channels, but as dynamic natural features that continue to alter the landscape. Fingers crossed for more rains in 2026. When they come you know where I will be!



1 From the EPA, “An ephemeral stream has flowing water only during, and for a short duration after, precipitation events in a typical year. Ephemeral stream beds are located above the water table year-round. Groundwater is not a source of water for the stream. Runoff from rainfall is the primary source of water for stream flow.” This is opposed to an intermittent stream which relies on groundwater and is only supplemented by rain.

5 MONTHS WITH TEST PLOT

By Kaitlyn Ray
Cal Poly SLO landscape architecture intern
DATE: Dec 01 2025

ON ART + CARE....

There is art in stewardship, in smallness, in care, in recognizing how that art becomes inscribed on a place. In short, this is what I saw at Test Plot: art inscribed upon a landscape as a result of many hands who care about their common home and about each other. The soul in the land’s caretakers, the sweetness in their interactions, and the buzzing life that springs forth from it all. These, surely, are all metrics of an artful place.

Interventions need not be immediately impressive or very large to make a difference. Small, piecemeal interventions done with Great Care mean infinitely more in the scheme of social landscapes to be loved rather than simply admired. Such interventions reach success on account of their radical outpourings of care: investment in a place paired with a desire for it to be excellent. The land needs people who care about it, listen to it, and who can form a kinship with it. This idea of small kinship is actually very big and very meaningful; this, I have understood more than ever during these last five months at Test Plot.

ON A PRACTICAL NOTE....

I became intimately familiar with the plants on our plots, refining my understanding of their character beyond identification. I was involved in cataloging and mapping existing plants, setting up iNaturalist profiles, designing ethnobotanical plant tags, and creating a huge Test Plot plant list with useful attributes for stewards. These, among other tasks, allowed me to better understand the nuance and character of ecological interconnectedness, as well as where people + care fit into it all.

This interconnectedness, the relationality of plants with humans, with each other, and with the rest of the environment, became most evident during the plant list creation. Plant-human relationships revealed themselves through a study of naming, propagation, care, and ethnobotany. A study of plant communities, ecosystems, and reproduction became a lesson in plants’ relationships with each other. A late addition, what species the plant hosts, revealed how specific plants and animals interact with and rely upon each other. Each, in some way, informed the way I see how environmental relationships develop and sustain themselves. Plant-human, plant-plant, and plant-environment: each an ecotone, representative of immense richness and diversity that can only be found in their intersections.

Understanding this made the work of land restoration so much richer; rather than simply knowing and designing for the end result, I can know and design for the interconnectedness + relationality that precedes and produces that result. It is a necessary step back; in a way, it is a way to see the bigger picture. Though, paradoxically, this “bigger picture” exists in knowing the nuance of the smaller pieces that make up that picture. Maybe “smaller picture” is better vocabulary.

Naturally, this idea also plays out in the necessity of care and the respect for labor that goes into land restoration, a manifestation of the human-land (or terrapersonal as my dear friend Ruth puts it) relationality. This, too, is something that the good folks of Test Plot uniquely practice.

ON ANOTHER PRACTICAL NOTE....

I unexpectedly became familiar with web design, (a tiny bit of) coding, marketing, social media, volunteer management, spreadsheets, procreate animation, and laser cutting. Being in such a tiny company was incredible, as it afforded me a ton of unexpected problem-solving opportunities. Did I know how to do everything that Jen asked me to do? No! Did I eventually figure them out though? Most of the time, yes! This proved to be rather empowering; while I may not have known exactly how to accomplish some tasks, I felt increasingly confident in my ability to problem solve my way through them. I am certain that, even later in my career, I will never know how to do everything; for that reason, I am extremely grateful to have had the opportunity to leverage my inexperience as a way to learn and to grow in confidence.

ACADEMIC APPLICATIONS....

Working here was the first time I had really come to understand what a seed bank entails. The concept was fascinating enough to inspire a term research project comparing passive revegetation strategies using native seed banks and active revegetation strategies using calculated seed mixes.

The internship also sparked a newfound interest in ethnobotany (which is good, because I spent good, quality time with the La Esquinita tags) Our Fall studio project was located on Chumash land in Santa Ynez, and, after speaking with some tribal members at the local museum, I decided to explore ethnobotany as it relates to the Chumash culture. My proposal of an ethnobotanical “mother plant” garden responded to the joint tribal desires to revitalize pathways of TEK transmission and restore ecological integrity. That idea would not have been possible without having first learned how Tongva and Kizh peoples understood their community’s kinship with their environment.

As I embark on my senior thesis project, (eek, scary!) I am more influenced by the Test Plot framework than ever, particularly as it relates to the social dimensions of land care. My time at Test Plot made it clear to me that I want to work closely with local organizations + nonprofits + charities. I absolutely adored the social aspect of my work, and I found so much joy and purpose in attending events and workdays where people can come together for a purpose larger than the individual. Going forward, I want to continue practicing “human care through land care,” building upon it to include themes of interpersonal relationships and social + environmental justice. 

TO CLOSE...

I want to express my gratitude for the entire Test Plot family. From graciously moving my first interview while I was in Nepal to not be at 2am, to letting me hold onto the internship for three months longer than agreed upon, and every micro-lesson in between, they have truly been a blessing. I am exceptionally thankful for the last five months, for every lesson and wise bit of knowledge that Jen has gifted to me, and for the groundedness + care which I look forward to taking into my career. Thank you Test Plot, I love ya!






STORMWATER WORKSHOP #1

Rainbow Canyon Test Plot 

DATE: December 07 2025

An Oral History by USC Students in Arch546

“This event felt genuinely healing and grounding for me. The mix of tired muscles, dirt on our hands from pulling weeds, and easy conversations with people who’d been strangers a few minutes earlier made being outside feel quietly joyful in a way I didn’t expect. It was really lovely to see Rainbow Canyon so alive. I also got to put my architecture school education to use by building a birdhouse with friends. It took all three of us, which felt both grounding and humbling, and I really hope the birds end up loving its slightly crooked, handmade charm.”




“Presenting our check dam proposal at the Test Plot community event on Sunday was one of the highlights of my semester. After weeks of finals and studio deadlines, it felt refreshing to step outside the classroom and talk with people who actually live near Rainbow Canyon. I enjoyed explaining our ideas and hearing how residents experience flooding, erosion, and changes in the landscape firsthand. Their reactions were thoughtful and encouraging, and it was exciting to see that people were genuinely interested in how design could improve the canyon. The experience reminded me why architecture and landscape design matter beyond drawings and models̶they can become part of real conversations and real places. It was also a nice break from academic pressure to engage with the community in a relaxed, open setting and see our work spark curiosity and discussion.”





“What a long and fruitful day. I had such a great experience not only being able to see our map sign-in board with the diversity of visitors from areas around LA, SoCal, and internationally, but to get my hands dirty and meet new people. The best moments were when I’d see an untouched pile of dirt and a plant besides it, signifying it needed to be planted. Someone else would be planting nearby, and I asked how they heard about the event. I learned about people who were friends with my classmates, people who attended last December’s workshop and kept up to date with the Testplot instagram, and people who came because their friend lived in the neighborhood and also came to volunteer. These were just beginnings of conversations until I got to meet two costume designers who appreciated spending time with people passionate about the outdoors and a recent grad in the California Climate Action Corps. The event was an opportunity to connect with people over a shared process of planting. For fun, if the day was named after a Spotify playlist, it’d be Beaming Grind Community Sunday Afternoon.”


“During the activities, the flood simulation felt really meaningful, and the mapping exercise was just as important. Marking where everyone came from helped me see how different perspectives shape the way we understand the site. Over the semester I watched Rainbow Canyon slowly grow from barren land into an ecosystem. and it added another layer of meaning to the work we did throughout the day. The tree-planting activity was also memorable—especially having to wrap the plant bases with netting to keep the roots from getting damaged. Building the birdhouses was probably the most fun, and it helped me understand structure in a very hands-on way. And since I worked in digital modeling and integrating information, seeing water move through the physical model made me realize how valuable real, tactile experience is for understanding flood patterns and the site itself.”




“I loved expanding the existing plots with new plants. We’ve been learning what’s growing well and what hs taken longer to etablish. We currently have 7 mini plots that focus on different microclimates and purposes: Two fire buffer plots alongside the homes that border the lower plots contain evergreen species and species that have a low leaf burn rate (see Las Pilitas for data), a riparian plot, two walnut woodland understory plots and two hillside plots that will stabilize the steep access point that connects to Ave 44. In total we planted over 240 native plants donated from Community Nature Connection and Chaminaude Nursery. I’m particularly excited to see how the Canyon Sunflower (Venegasia carpoides) does in the woodland plots as it seems like it should be right at home in this shady, protected canyon. It will add much needed color and brightness.”
