The city's overall park access is a national benchmark. The off-leash system serving one of the country's highest dog populations is a separate — and far more broken — story. This is what happens when a city prices its dogs out of its own parks.
Seattle Parks & Recreation has, accurately, branded itself a national leader on park access. 99% of residents live within a half-mile walk of a park — higher than every U.S. city except Boston and San Francisco. The problem: almost none of those parks allow dogs off-leash. Look closely at the 14 designated OLAs and the story inverts.
Trust for Public Land's access metric uses a half-mile walkshed — the distance most people are willing to walk before getting in a car. By that measure, Seattle's park system is extraordinary — 99% of residents live within a 10-minute walk of a park. Its off-leash system, measured the same way, is among the worst of any major West Coast city.
The 10-minute walk is the standard used by Trust for Public Land, the National Recreation and Park Association, the Urban Land Institute, the National Park Service, and the CDC. It is the standard Seattle Parks cites when celebrating the city's park access generally. For dog parks specifically, SPR switched to a 2.5-mile standard — 5× more permissive.
Apply TPL's 10-min standard to OLAs: 9.6% of Seattle residents covered. Apply SPR's 2.5-mi standard: 79.4%. Same city. Same residents. The only thing that changed is the yardstick.
2.5 miles is approximately the length of the Green Lake loop — walked one way. Or, framed as a daily commute: 50 minutes each way to reach a dog park.
The map below shows Seattle's 14 existing off-leash areas, the two under construction for a fall 2026 opening, the three in longer-term planning, and the circular half-mile walksheds around each. The white space is the gap. Large parts of North Seattle, Central District, West Seattle, and nearly all of Capitol Hill lie outside a 10-minute walk of any OLA.
Counting "14 OLAs" flatters Seattle. Of those 14, half are under one acre. Four pocket OLAs are under a quarter-acre. The three largest — Magnuson, Westcrest, Genesee — hold nearly two-thirds of the city's total off-leash acreage. Everything else is a postage stamp.
The median Seattle OLA is 1.0 acre. The smallest (Kinnear) is about one-tenth of an acre — smaller than two tennis courts. For context: Portland's smallest fenced OLA is larger than Seattle's third-smallest.
Even allowing that some small OLAs are acceptable for neighborhood use, most of Seattle's are missing the basic amenities that make an OLA practically usable. Citizens for Off-Leash Areas (COLA) surveyed OLA users and published an amenity inventory; the headline numbers are bleak.
COLA's user survey also found that 78% of total OLA acreage is in just four parks (Magnuson, Westcrest, Genesee, Dr. Jose Rizal), and that the #1 reason non-OLA users don't use OLAs is that they're not conveniently located. Residents in practice regularly use only four of the 14 sites: Magnuson, Westcrest, Golden Gardens, and Woodland. The rest are too small, too far, or in the case of Kinnear, too unsafe for most users to consider.
"Too small" is often treated as a vibes judgment. It isn't. Three independent authorities publish overlapping standards for what size a functioning neighborhood dog park should be, and what per-dog capacity a park of a given size can support.
Applied to Seattle's 14 OLAs, the implications are specific. Seven of 14 are below the AKC 1-acre floor. Four are below 0.25 acre — the upper end of "pocket dog-run" territory. And the implied peak capacity at the 100 sq ft per dog industry standard is, for the smallest OLAs, painfully small:
| OLA | Area (sq ft) | Cap at 100 sq ft/dog | Cap at 75 sq ft/dog | Below AKC 1-ac min? |
|---|---|---|---|---|
| Kinnear | 4,356 | 43 | 58 | Yes — 0.1 ac |
| Plymouth Pillars | 6,534 | 65 | 87 | Yes — 0.15 ac |
| Regrade | 8,712 | 87 | 116 | Yes — 0.20 ac |
| Magnolia Manor | 17,424 | 174 | 232 | Yes — 0.40 ac |
| Denny Park | 32,670 | 326 | 435 | Yes — 0.75 ac |
| Lower Woodland | 32,670 | 326 | 435 | Yes — 0.75 ac |
| Golden Gardens | 41,382 | 413 | 551 | Yes — 0.95 ac |
| Dr. Jose Rizal | 56,628 | 566 | 755 | No — 1.3 ac |
| Northacres | 60,984 | 609 | 813 | No — 1.4 ac |
| Blue Dog Pond | 74,052 | 740 | 987 | No — 1.7 ac |
| I-5 Colonnade | 78,408 | 784 | 1,045 | No — 1.8 ac |
| Genesee | 117,612 | 1,176 | 1,568 | No — 2.7 ac |
| Westcrest | 239,580 | 2,395 | 3,194 | No — 5.5 ac |
| Magnuson | 392,040 | 3,920 | 5,227 | No — 9.0 ac |
Comparing total OLA acreage across cities is harder than comparing counts, because cities define "off-leash" differently. Portland has 30+ DOLAs but most are unfenced voice-control areas. San Francisco counts 42 dog-friendly sites including small DPAs (Dog Play Areas) carved into larger parks. Vancouver BC counts 36 OLAs including time-restricted areas. Seattle counts only fully-fenced, dedicated OLAs.
Normalizing for these definitional differences is imperfect. Below is a best-effort comparison of OLA acreage per capita, with caveats noted inline.
| City | OLA count (methodology) | Est. total OLA acres | OLA acres per 10K residents | Largest single OLA | Median OLA size |
|---|---|---|---|---|---|
| Seattle, WA | 14 (all fenced) | ~26 | 0.32 | 9.0 (Magnuson) | 1.0 |
| Portland, OR | 33 (most unfenced) | ~85 | 1.29 | 1,400 (Thousand Acres)* | 1.3 |
| San Francisco, CA | 42 (mix fenced/unfenced) | ~120 | 1.38 | 14 (Fort Funston) | 1.5 |
| Vancouver, BC | 36 (mostly time-restricted) | ~168 | 2.54 | 40 (New Brighton) | 2.3 |
| Austin, TX | 13 (mix) | ~680* | 6.63* | 293 (Red Bud Isle, on-leash optional) | 2.0 |
* Austin and Portland's "largest" entries are off-leash hiking/nature areas, not traditional fenced dog parks. Excluding these outliers brings Austin's total acreage to ~80 and Portland's to ~60, but the per-capita count still substantially exceeds Seattle. Vancouver BC's large-acreage number (168 acres) is from its own 2017 People, Parks & Dogs Strategy and reflects time-restricted shared-use areas on beaches and fields.
When a city provides insufficient legal space for an activity its residents are going to do anyway, the activity moves underground. In Seattle, this means tens of thousands of dogs using regular parks, playfields, and trails off-leash every day — documented by SPR itself, and acknowledged in the department's own planning documents.
In 2016, as part of the research that became the People, Dogs and Parks Strategic Plan, SPR surveyed Seattle dog owners about their compliance with leash laws. The results have never been the centerpiece of any SPR communication, but they're damning.
"Park rangers routinely encounter dogs off-leash in parks and on trails. These encounters have a direct impact on park users who feel unsafe, and on native wildlife in Seattle's natural areas." — Seattle Parks & Recreation, People Dogs and Parks Strategic Plan (2017)
This is not a situation of a few irresponsible owners. Two out of every five dog owners admit to illegally off-leashing in parks — to a survey run by the agency that enforces leash laws. The actual rate is almost certainly higher. SPR has acknowledged this is a product of insufficient supply: the department's stated goal in the 2023 OLA Expansion Study is "to advance [the] goal of creating OLAs that are increasingly within walking distance of residents and allow SPR to fill in geographic gaps where neighborhoods lack access to an OLA."
The data also suggests the problem is worsening, not improving. Find It Fix It complaints about off-leash dogs in parks have been rising year-over-year as the city's population has grown while the OLA count has remained frozen.
Roughly two-thirds of Seattle residents don't have a 10-minute walk to an OLA. The alternative to a 25-minute drive with a 70-pound dog is a local park. Most of the 39% are in this category.
A 0.1-acre OLA (Kinnear, Denny) or 0.2-acre OLA (Regrade, Plymouth Pillars) is unusable for any dog that actually needs to run. Owners with high-energy dogs rationally choose a larger illegal space over a tiny legal one.
This is the least-discussed driver but increasingly salient. Several of Seattle's OLAs — most notably Kinnear and Plymouth Pillars — sit adjacent to or are accessed through areas with chronic homeless encampments and associated safety concerns. The detailed Kinnear case is below.
Seattle has created a system where compliance is a minority behavior, and is punishing the 61% who do comply by continuing to underbuild for the 39% who don't. The enforcement arm (Animal Control, Park Rangers) is effectively treating a supply problem as a behavior problem.
Kinnear is an object lesson in how an undersized OLA in a safety-compromised park becomes a driver of illegal off-leash use at nearby parks, rather than a solution. It's Seattle's smallest OLA at 0.1 acres — a corral about the size of two tennis courts — at the bottom of a hillside greenbelt on the southwest slope of Queen Anne Hill. For the roughly 33,000 residents of Queen Anne and Magnolia (Seattle's most heavily dog-owning neighborhoods by some surveys), Kinnear is the only city-designated OLA within walking distance.
The problem with Kinnear isn't the OLA itself. It's that the park it sits in has been a chronic homeless encampment site for over 20 years, and the OLA is on the far side of the encampment from the parking lot and main entrance.
Why this matters for the broader OLA conversation: Kinnear illustrates the system failure in microcosm. The OLA is technically available, so SPR's gap analysis counts Queen Anne as "served." In practice, many Queen Anne dog owners skip Kinnear entirely — either driving to Magnuson or Magnolia Manor, or illegally using Kerry Park, Rodgers Park, Queen Anne Bowl, or the nearby school playfields. The result: a perfectly predictable pattern of illegal off-leash use in a neighborhood the map says is covered.
This is not unique to Queen Anne. Plymouth Pillars in Capitol Hill, Denny Park in South Lake Union, and Regrade in Belltown all sit in or immediately adjacent to areas with chronic encampment and public-safety concerns. The "14 OLAs" number assumes all 14 are functional for their intended neighborhoods. In practice, a measurable share are effectively nominal.
Stacking the Part I, Part II, and Part III findings together produces a system profile that is internally consistent and, honestly, worse than the headline numbers suggest.
The headline version: "Seattle has one of the best park systems in America." The honest version: "Seattle has one of the best park systems in America for people who don't own dogs."
10-minute walkshed methodology. TPL defines the 10-minute walk as a half-mile service area calculated along the public road network, cut by physical barriers (highways, train tracks, rivers without bridges). TPL publishes the "99% of Seattle residents" figure using this methodology for all parks, but does not publish a dog-park-specific version. The OLA walkshed figures on this page (9.6% at 10-min, 79.4% at 2.5-mi, computed April 2026) come from a repo-derived network analysis: scripts/compute_walkshed.py runs osmnx against Seattle's OpenStreetMap walk network (projected to UTM 10N, physical barriers respected) to compute per-OLA isochrones, and scripts/population_coverage.py intersects the union with 2020 Census block-group population clipped to the Seattle city boundary. The isochrone algorithm uses convex hulls of reachable network nodes, which tends to slightly overestimate walkable area at the boundary of each OLA's reach — so the true coverage figure may be a little lower than 9.6%, not higher. Output at data/walkshed/population_coverage.csv; full methodology in METHODOLOGY.md. The older "~33%" straight-line estimate previously on this page has been superseded.
Peer-city OLA counts. The methodological differences between cities are real and material. Portland's 33 "DOLAs" include 20+ unfenced voice-control areas; Seattle counts zero unfenced sites. If Seattle redefined its approach to include unfenced designated off-leash spaces (as several other cities do), the count would be higher — though SPR has publicly stated a preference for fenced sites for liability and environmental-impact reasons. The comparison in this report intentionally uses each city's own count, which is the fairest apples-to-apples approach even with methodology differences.
OLA acreage estimates. SPR publishes per-OLA acreage on its individual park pages, but the numbers are inconsistent — Magnuson is variously stated as 8.6, 9, or 9.6 acres; Westcrest as 3.8, 5, 8.4, or 8.5 acres. Where ranges exist, this report uses the mid-value from the most recent SPR page. Peer-city acreage totals are rougher (±20% is reasonable) because no city publishes a single authoritative inventory in the way Seattle does.
Kinnear Park timeline. The timeline is drawn from contemporaneous reporting: Seattle Weekly (2007), Seattle Times (2008), Aussiedoodle Adventures (2020 — a dog-owner blog), Fix Homelessness (2023), and KOMO News (2025). The Dewey Potter quote from 2008 ("we try to look the other way") is verbatim from the Seattle Times piece and reflects SPR's posture toward the Kinnear encampment at the time; SPR's current stated posture is more active, but the cycle of clearance-and-return documented in the KOMO April 2025 piece suggests operational practice has not fundamentally shifted.
"Dogs per OLA" calculation. Using Seattle's widely-cited 150,000 dog population (Seattle Humane, Cascade PBS) divided by 14 OLAs gives roughly 10,700 dogs per OLA — the same order of magnitude as the residents-per-OLA ratio (58,300). SPR's own 2023 Expansion Study cites higher dog-population estimates (up to 400,000), which would raise the ratio to ~28,500 dogs per OLA. Either way, the density is an outlier relative to peer cities.

On this report's direction. The framing of this report ("a system failure") is not how SPR would describe its own OLA system, and is not how TPL would describe Seattle's park system as a whole. Both organizations have legitimate reasons to foreground positive metrics — SPR because overall park access is genuinely world-class and OLA investment has recently increased, and TPL because its ranking system appropriately weights total park access more heavily than any single amenity. This report is not intended to rebut those framings; both are defensible and true. It is intended to present the specific slice of the data that describes the off-leash system, which by any honest reading is a substantial underperformer relative to Seattle's own standards and peer-city benchmarks.
