What works, and what Seattle hasn't tried.
Parts I and II document the supply gap and the access gap. Part III looks forward through three questions: which of Seattle's existing off-leash areas (OLAs) function well and why, what shared-use looks like in cities that have run it for decades, and what public land outside Seattle Parks' portfolio could host off-leash space without new Park District dollars.
What works
Three Seattle OLAs that draw sustained community support, and what they share.
Section 3bShared-use
The off-leash-hours model: what New York's record shows, and what it doesn't.
Section 3cNon-SPR land
WSDOT, Seattle City Light, Port of Seattle: public land SPR does not manage but Seattle hosts.
What works: three OLAs with a steward, a structure, and room.
The Enforcement data shows where the system is failing. Three of Seattle's 14 OLAs show what holds up, and all three have organizational structure behind them: a site-specific nonprofit at Magnuson (now dormant), system-wide stewardship by COLA at Genesee, and a recent Park District-funded renovation at Westcrest. Each has enough physical area to absorb demand (9.0, 2.7 and 8.4 acres against Kinnear's 0.124). Part II measured distance. What separates these three is size and stewardship.
Magnuson — the site-specific steward model, now dormant
Magnuson is a structural outlier on land area, physical features (shoreline, gravel paths, woods), and governance. For roughly two decades it was stewarded by the Magnuson Off-Leash Group (MOLG), an all-volunteer 501(c)(3) that raised donations, ran volunteer maintenance days, and partnered formally with Seattle Parks, the closest Seattle parallel to the Portland or San Francisco "dog park friends" model. MOLG's website and public presence have since gone dark (last visible activity late 2023), so the site-specific model it represented is, for now, dormant.
The 367 citations logged at Magnuson 2014–2026 (Enforcement top-20) count the whole park. Magnuson is the biggest park with the biggest footprint and draws traffic from across the region, and the enforcement records name the park, not the fence, so they cannot say how many contacts were inside the OLA versus on the athletic fields and shoreline outside it.
Genesee — the COLA-steward model
COLA is the system-wide advocacy and stewardship group for Seattle's OLAs, and Genesee is one of the sites where its volunteer stewardship is most visible. SPR's 2017 plan credits COLA with the initial list of pilot sites for the 1996–97 program and records a standing umbrella agreement with the group dating from the late 1990s; steward volunteers continue to show up at Genesee, Westcrest, and other OLAs. Where MOLG was site-specific, COLA works across the whole system.
Genesee's physical design has held up: a separated small-dog area, multiple gates, drainage that handles Seattle winters. The 152 citations logged there 2014–2026 name Genesee Park & Playfield as a whole, athletic fields included, not the OLA.
Westcrest — the recent-investment model
The 2021–2022 Park District renovation at Westcrest addressed drainage, erosion control, access and parking, and accessibility, reopening June 10, 2022. Scope was maintenance-driven, not a rebuild: rock-lined swales, piping and outfalls, sediment traps, regraded high-use areas, accessible pathways. Community input came through the Highland Park Action Committee; ongoing stewardship is credited to COLA. Its 122 enforcement-data citations 2014–2026 are lower than the four biggest host parks'.
SPR's own 2016 capital-priority list (PRR C266465, Bates 00168) priced $1.15M–$2.22M of deferred work across the 14 OLAs in 2016 dollars, against Park District OLA maintenance of $103,000–$117,000 a year. In its February 2024 Expansion Study deck (Bates 00416), SPR named Capitol Hill, Ballard and Northgate as unaddressed gaps and listed East Queen Anne Playfield as a recommended future site, pending field-scheduling discussions with the community. Those are SPR's words, not this site's.
Shared-use: the off-leash-hours model.
Several U.S. cities designate time-windowed off-leash access in existing parks rather than building new fenced OLAs. New York has run it formally since 2007 and informally since roughly 1986. Adopting it in Seattle would change the coverage figure without new capital.
New York City: formal since 2007, functional longer
NYC Parks codified its Off-Leash Hours policy on April 10, 2007. In designated areas of participating parks, licensed and vaccinated dogs may be off-leash from park opening until 9:00 AM and from 9:00 PM until park closing; normal leash rules apply otherwise (NYC Parks). It runs alongside NYC's fenced dog runs, not instead of them, and the off-leash footprint, sections of Central, Prospect, Riverside and Van Cortlandt plus dozens of neighborhood parks across all five boroughs (directory), dwarfs Seattle's 14 fenced OLAs.
NYC publishes no longitudinal evaluation of the policy: no official citation, complaint, or injury tracking. What stands in for it is longevity, nineteen years of formal operation renewed through administrations with different parks politics, and no reversal. The National Recreation and Park Association treated it as the mature U.S. example in a November 2018 Parks & Recreation law review; Boston and Chicago run parallel time-based systems, and Chicago's fenced Dog-Friendly Areas sit alongside them. None of this proves clean transfer to Seattle, with its different density, topography, rainfall, enforcement institutions, and parks-homelessness dynamics. What it shows is that a city of eight million has run time-zoned shared-use for nearly twenty years without catastrophic failure.
Seattle's 14 OLAs cover 11.7% of residents within a 10-minute walk (Part II). Time-windowed access to existing large parks such as Green Lake, Volunteer Park, Lincoln Park, Seward Park and Discovery Park would change that figure without the multi-year capital timelines of new dedicated OLAs.

Non-SPR land: public space SPR does not manage.
Seattle's OLA supply is bounded by SPR's real-estate portfolio, but two existing OLAs already sit on other agencies' land: I-5 Colonnade on WSDOT right-of-way and Magnolia Manor on a Seattle Public Utilities reservoir site, and SPR's 2017 plan records two City Light sites considered in the 1996–97 pilot (pp. 11–12). The precedent exists; what's missing is an inventory. COLA raised this in its comments on SPR's 2023 Off-Leash Area Expansion Study, which did not consider non-SPR public land.
WSDOT: state highway right-of-way
WSDOT manages land adjacent to every state-numbered road in the city. Some is unusable (active lanes, on-ramps), but a portion is landscaped setback, substantially fenced, and distant from traffic. I-5 Colonnade, under I-5 on WSDOT land, is the functioning precedent.
Seattle City Light and SPU: corridors and utility property
City Light owns transmission corridors across the city, several already hosting informal recreation (walking trails, community gardens); they are typically fenced, signed, and maintained on a schedule. SPU's Magnolia Manor site shows a utility parcel can host an OLA outright.
Port of Seattle: waterfront and industrial-adjacent
The Port owns substantial waterfront property. Most is industrial and security-restricted, but edge parcels (landscape buffer, parking, unused waterfront) may be compatible with off-leash use within the Port's operational constraints.
Framed as "where can SPR build a new OLA on SPR land?" the answer is a multi-decade capital cycle. Framed as "where inside city limits is there public land where dogs could be off-leash without a new capital project?" the answer involves agencies SPR has partnered with before, on two of the existing 14.
