On October 24, families in costumes will gather at the shelters at Maple Leaf Reservoir Park at 2:00 PM, then walk a parade route past storefronts most of them shop at every week. It is the kind of afternoon that feels entirely aboveground: candy, dog costumes, a few hundred neighbors on the same lawn they were on in August for outdoor movies and will be on again in October for a community meeting.
None of them are standing on solid ground. They are standing on a lid.
The Park That Isn't Actually a Park
Maple Leaf Reservoir Park looks like a normal 16-acre neighborhood park, with sport courts, a children's play area, and a plaza that looks out toward Mount Rainier and Lake Washington. What it actually is sits underneath: two sealed concrete cells holding 60 million gallons of the city's drinking water, built by Ferguson Construction with structural engineering by MWH Americas. The cells are separated by an interior wall so Seattle Public Utilities can drain and clean one half while the other stays in service, and the whole structure is held up by 768 cast-in-place concrete columns inside walls 22 inches thick and 21 feet high.
The city began planning to bury the reservoir in 2009, part of a citywide program that eventually replaced six open drinking-water reservoirs with underground structures and put parks on top of the lids, including Cal Anderson Park over the old Lincoln Reservoir and Jefferson Park over Beacon. Maple Leaf's version opened in October 2013. The park expanded the existing 5-acre Maple Leaf Playground into a 21-acre combined space, and the project's roughly $55 million budget included about $5 million specifically for the park amenities, paid for through the Parks and Green Spaces Levy along with a Department of Neighborhoods grant and a private donation from the Bishop family.
There is one visible clue to what's underneath. Near the upper viewpoint sits Confluent Boulders, a sculpture by artist Patrick Marold made from two glacial boulders, one pulled from the Tolt River watershed and one from the Cedar River watershed, the neighborhood's two actual water sources. It was funded through Seattle Public Utilities' 1% for Art program.
The Fall Calendar Sitting on Top of It
Every recurring Maple Leaf tradition runs through this same lawn, and the fall lineup is already moving. Here's what's on the books:
| Event | Date | Time | Location |
|---|---|---|---|
| September Silent Book Club | September 20, 2026 | Evening | Maple Leaf Reservoir Park |
| Fall Community Meeting | October 14, 2026 | TBD | Maple Leaf Reservoir Park |
| Halloween Parade | October 24, 2026 | 2:00 PM | Maple Leaf Reservoir Park |
Movies by the Tower, the neighborhood's summer outdoor film series, already wrapped its fifth season on August 8 with a screening of Superman under the water tower's silhouette. That means by the time the Halloween Parade steps off, this single patch of grass will have hosted a movie night, a book club, a community meeting, and a costume parade in the space of about eleven weeks.
None of it happens by accident or by city budget. The Maple Leaf Community Council, the all-volunteer group behind every one of these events, has run the neighborhood's civic life since 1983, when Puni Hokea and Peter Orser founded it partly to fight upzoning along Roosevelt Way NE. The council isn't affiliated with city government. It runs on membership dues, with tiers for households, individuals, seniors 65 and up, and students, plus occasional grants and sponsorship from local businesses. In 1986, Seattle Mayor Charles Royer nominated Maple Leaf for the national "Neighborhood of the Year" award from Neighborhoods USA, and the neighborhood won it.
The Same Names Keep Showing Up
August's Movies by the Tower gives a clear look at who actually funds these traditions. Seattle Credit Union presented the series, Scarecrow Video curated and hosted it alongside the council's Events Committee, and the supporting cast was almost entirely small, local, and specific:
- Fresh & Clean Garment Care
- Aegis Living Ravenna
- Moonlight Tattoo Seattle
- Rain City Dentistry
- Billings Middle School
- RUG Little League
- The Watershed Pub & Kitchen
- Project 9
- ReAnimated Music
- Cafe Javasti
- Math 'n Stuff
That's a dry cleaner, a senior living community, a tattoo shop, a dental practice, a middle school, a youth baseball league, a neighborhood pub, and a coffee shop, all putting money into the same lawn. Aegis Living Ravenna sits on the former site of Waldo Sanitarium, an osteopathic hospital that operated near the reservoir starting in 1924 before relocating toward Northgate in the 1960s and closing in 1985. The building changed use, but the address stayed part of the neighborhood's civic footprint.
Why There's No Dog Park (and Why the Wind Is So Good)
The reservoir underneath doesn't just sit there quietly. It shapes what the park can and can't be.
Below the sport courts and picnic tables, 768 concrete columns hold up two sealed cells that together store 60 million gallons of drinking water still in active service.
When neighbors pushed for a fenced dog park on the upper lawn during planning, Seattle Public Utilities said no. The lid is sealed and waterproof, but digging in or adding heavy fixtures near the reservoir cover wasn't something the utility was willing to risk, even on the surface layer built specifically to hold a park. What residents got instead is a hitting wall for solo pickleball practice, sport courts, and a wide, treeless upper lawn that has become known among local kite flyers for catching brisk southwesterly wind with nothing in the way. That same open sky comes from elevation. The high point of Maple Leaf, at 92nd and Roosevelt, sits 466 feet above sea level, the third-highest point in the city, which is part of why the park's viewpoint clears fir trees to show downtown Seattle and the Space Needle beyond.
What's Changing Just Outside the Gate
The park itself isn't the only piece of Maple Leaf infrastructure in motion this year. In August 2026, the Seattle Department of Transportation finished the design for a paving and safety overhaul of Roosevelt Way NE and Pinehurst Way NE, the two streets most families use to actually reach the park. The corridor, stretching from NE 92nd Street to 15th Ave NE, has seen 93 crashes over the past five years involving people walking, biking, and driving. The redesign adds protected bike lanes, new pedestrian refuge islands, upgraded curb ramps, and a rapid flashing beacon crossing at NE 113th Street, funded partly by an $8.7 million Federal Highway Administration grant alongside the Seattle Transportation Levy. Construction is scheduled to begin in 2027.
Two schools sit directly along this route: more than 650 students attend Hazel Wolf K-8 near Pinehurst Way, and more than 350 attend Olympic View Elementary near Roosevelt Way. The project also connects to the Maple Leaf Neighborhood Greenway at NE 103rd Street, a route that already links the park toward Roosevelt, Green Lake, and the University District. You can see the full design boards on Seattle's project page for the Roosevelt and Pinehurst Way NE Paving & Safety Project.
One Lid, One Council, One Small Network
Take the reservoir, the volunteer council founded in 1983, and the same dozen small businesses writing sponsorship checks year after year, and what you get isn't really a park calendar. It's a neighborhood that has quietly organized its entire social life around one piece of buried city infrastructure and kept it running on membership dues and goodwill for over four decades.
If you want to see it in person, the Halloween Parade steps off at 2:00 PM on October 24 at the park shelters, and the council's Fall Community Meeting on October 14 is open to anyone curious about what else is coming. Details for both are on the Maple Leaf Community Council's events page.
Chris Haynes and the team at Seattle Home Guide keep a running local eye on what's changing across Shoreline and North Seattle neighborhoods like Maple Leaf, from community traditions to the infrastructure projects reshaping how people get around. If you're ever curious what your own home might be worth in this market, that conversation is only a click away too.
