On Saturday, October 24, TreePeople is giving away 200 coast live oak seedlings at its park on Coldwater Canyon, just over the ridge from the hillside streets south of Ventura. The tree is free. Choosing where it goes is the part that costs something. A coast live oak can grow wider than many hillside side yards, it needs very different watering in year three than in year one, and the City of Los Angeles protects coast live oaks once the trunk reaches 4 cumulative inches in diameter, measured 4.5 feet above the ground. The hole you dig this fall settles part of your yard's layout for longer than most remodel plans run.
So the useful question for a Studio City Hills homeowner is where on a sloped lot a tree can grow for the next quarter century without running into anything you might want to build later. Whether you want an oak at all is the easy part.
Two hundred seedlings, one Saturday morning
Oaktoberfest runs from 10 a.m. to 1 p.m. TreePeople asks attendees to register in advance on its events page to receive a seedling. The giveaway is part of Rooting for LA, the organization's commitment to plant and care for 28,000 trees by 2028. TreePeople lists cooler neighborhoods, restored habitat and greener schoolyards among the goals.
Getting there from the hills comes with one new detail. TreePeople's own parking is limited, and its events page points overflow drivers to Wilacre Park on Laurel Canyon Boulevard, roughly a 35-minute hike up to TreePeople headquarters. Wilacre stopped being free this year. Since May 20, 2026, the Mountains Recreation and Conservation Authority has charged $7 for up to two hours, with a four-hour daily maximum per vehicle. The authority says the County of Los Angeles had covered maintenance there since 2014 and can no longer fund it after budget cuts. Two hours is tight for a 35-minute climb each way plus a pickup line, so it helps to plan the morning around the meter.
The four-inch line
The city's protected tree guide names California live oak, Quercus agrifolia, by name, along with valley oak, Southern California black walnut, western sycamore and California bay laurel. The protection applies on private lots too. The Urban Forestry Division at StreetsLA says it has authority over protected native species on private property as well as trees in the public right-of-way.
The ordinance generally requires a permit before a protected tree is removed or relocated. Its definition of "removal" also covers more than cutting a tree down. It includes actions that kill the tree, such as damaging roots, hitting it with machinery or changing the grade around the trunk inside the dripline. On a hillside lot, regrading is how retaining walls, terraces, pool decks and widened driveways get built. The municipal code sections list their most recent amendment as Ordinance 186,873, effective February 4, 2021.
The same code has an exception that applies directly to a giveaway tree. Its definition of a protected tree leaves out any tree or shrub grown or held for sale by a licensed nursery, and trees or shrubs "planted or grown as a part of a planting program." Oaktoberfest is part of TreePeople's Rooting for LA planting initiative. None of the sources we reviewed say whether a seedling a homeowner takes home from a program like that and plants in their own yard falls under the exception. The Urban Forestry Division is the office that oversees protected species on private property, so it's the place to get that answer for a specific tree. Either way, the four-inch threshold and the dripline grading language are good reasons to place the tree as if protection could apply.
Here is how the seedling's life lines up with what the sources say:
| Stage | What the sources say |
|---|---|
| Planting, late October to November | CNPS calls the cooler weather of late October and November a good time to plant |
| First 2 to 3 years | UC Master Gardeners say newly planted oaks need regular watering until established |
| Trunk reaches 4 inches at 4.5 feet | Coast live oaks of this size are protected, subject to the code's nursery and planting-program exception |
| 20 to 25 years | UC Oaks says the tree may take this long to fill the space you gave it |
| Mature | Roughly 20 to 82 feet tall, depending on the source |
No source we found gives a timeline for when a seedling crosses the four-inch mark. Theodore Payne Foundation describes coast live oak's growth as moderate, and Calscape says moderate to slow. Four inches of trunk is still a young tree next to the canopy sizes below, so the placement decision really happens in the first weeks.
Siting a tree that wants decades of room
Mature-size estimates differ a lot. Theodore Payne Foundation lists coast live oak at about 20 to 75 feet tall and 30 to 60 feet wide. Calscape gives 25 to 82 feet tall and 15 to 35 feet wide. Even the narrower figure is wider than many side yards on the hillside streets between Laurel Canyon and Vineland.
UC Oaks recommends a site with as much room as possible for roots, trunk and canopy. It says the tree may need 20 to 25 years to fill the space. We found no official minimum distance between a coast live oak and a house, foundation or driveway, so be wary of anyone quoting one as a rule.
Because the dripline is where the ordinance's grading language applies to protected trees, and where UC Master Gardeners warn against grade changes around any established oak, it helps to walk the lot with a few questions before digging:
- Where might a future retaining wall, terrace or stair run, and would a 30-foot-wide canopy's dripline cross it?
- Is there a driveway or parking pad you might widen later?
- Does the spot sit at the bottom of a slope where soil could someday be added around the trunk, or at the top where it could be cut away?
- Will the tree be far enough from planted beds that it won't get their summer watering every week?
The last question leads straight into how this tree wants to be watered.
Three summers of care, then mostly hands off
TreePeople's new-tree guidance is to set the root crown level with the surrounding soil and keep mulch pulled back from the trunk. According to UC Master Gardener guidance, a newly planted oak needs regular watering until it is established, usually after two to three years. The same guidance warns against changing the soil grade or compacting soil around established oaks. UC Oaks also says watering a seedling through its first summer or two matters.
After that, the care reverses. UC Oaks and California Oaks both warn against frequent summer watering of established oaks, especially near the trunk. UC Oaks recommends letting the soil dry out between any extra waterings in the dry season. An oak planted in the middle of a lawn or a drip-irrigated bed gets the opposite of what it needs once it matures. That makes the siting question and the watering question the same question.
The timing works in the seedling's favor. The California Native Plant Society's Redbud chapter recommends fall planting and points to late October and November as good months, and UC Master Gardeners note that fall planting lets new plants benefit from winter rain. A seedling that goes into the ground the last week of October lines up with that window.
Making a weekend of it at Coldwater Canyon
Oaktoberfest falls in the middle of three TreePeople events on consecutive days:
- Friday, October 23: Moonlight Hike. Check-in starts around 6:30 p.m., music begins shortly after 7 p.m., and hiking groups head out at 8 p.m. Tickets are sold in advance, and TreePeople encourages carpooling.
- Saturday, October 24: Oaktoberfest Tree Giveaway. From 10 a.m. to 1 p.m., with advance registration for a seedling.
- Sunday, October 25: Community Reading of "Do You Speak Tree?" At 11 a.m., author Josh Oaktree reads his nearly wordless graphic novel outdoors under the coast live oaks, and the audience helps make up the story. It's free, and kids are invited to come dressed as their favorite animal or tree.
More moonlight hikes are on the calendar for November 20 and December 18.
If the 200 seedlings run out, or you'd like a larger container tree, the Theodore Payne Foundation nursery at 10459 Tuxford Street in Sun Valley is open year-round, Tuesday through Saturday, 8:30 a.m. to 4:30 p.m. The foundation's online coast live oak listing has shown stock at Los Nogales Nursery and none at Sun Valley. Inventory changes, so check before you drive over.
Wherever the tree comes from, it will want the same 20 to 25 years of room, the same light hand with summer water, and the same untouched soil inside its dripline.
If you're thinking about where an oak fits alongside a future terrace, wall or addition on your hillside lot, Bryan Abrams has walked a lot of these streets and can talk through how lots like yours have changed over the years. Schedule a Studio City market consultation, and bring a photo of the spot you have in mind.
