Splash pad coverage, every state, compared

The 2026 benchmarks count only verified, publicly accessible splash pads. A pad is verified when at least one Tier 1 source (the operating municipal parks-and-recreation department, county park district, or state parks system) and at least one corroborating secondary source confirm its existence, location, and operating status. Pads on HOA-only spray decks, country-club kid pools, paid resort water features without public day passes, and indoor recreation-center facilities are excluded categorically; commercial water parks are tracked in a separate vertical and not counted here.

Decommissioned and defunct pads are excluded from the live count and logged in the public changelog rather than silently removed. Per-capita normalization uses US Census 2020-2024 population estimates, expressed as verified pads per million residents and then converted to a 1-51 ordinal rank across all 50 states plus the District of Columbia. The directory captures an estimated 12-17% of the true national installed base, so absolute counts are reported as ranges rather than precise figures, and per-capita rankings should be read as relative ordering rather than saturation estimates.

Data freshness is the April 2026 snapshot. The same source-priority and three-pass-verification rules described in our editorial methodology apply to every record counted here. Parks departments and researchers can request the underlying state extracts via the open-data feed; corrections are processed within 24-48 hours through the submit channel.

By raw verified count, the top 10 states are Texas, California, Florida, Ohio, New York, Illinois, Georgia, North Carolina, Arizona, and Pennsylvania. Texas leads with an estimated 650-760 verified pads, California follows in the 620-720 range, and Florida lands at 500-580. Ohio is the most under-reported state in this group: cross-referencing parks-department capital plans for Cleveland, Columbus, Cincinnati, Toledo, Akron, and Dayton produces a 420-480 range that places it solidly in the national top four despite rarely being framed that way in national press.

The top-10 list maps closely to population-weighted heat exposure. Eight of the ten sit in the Sun Belt or in dense legacy industrial corridors with active parks departments and recurring summer heat events. The two outliers — New York and Pennsylvania — reflect Northeast metro density and decades of municipal pool-to-pad conversions rather than a long operating season. Counted in absolute terms, these ten states hold roughly 55-60% of all verified pads in the directory, a concentration that shapes both press coverage and capital-planning benchmarks.

• 1. Texas — 650 – 760
• 2. California — 620 – 720
• 3. Florida — 500 – 580
• 4. Ohio — 420 – 480
• 5. New York — 320 – 360
• 6. Illinois — 260 – 290
• 7. Georgia — 210 – 240
• 8. North Carolina — 190 – 210
• 9. Arizona — 290 – 320
• 10. Pennsylvania — 250 – 280

Normalize for population and the leaderboard flips. The top 10 by pads per million residents — Wisconsin, Iowa, Nebraska, Kansas, Minnesota, Oklahoma, Indiana, Ohio, North Dakota, and South Dakota — is dominated by heartland states with strong municipal park traditions. Most never appear in national coverage of splash-pad infrastructure. Three of the ten have populations under three million; two have populations under one million. Per-capita coverage tracks civic intent and parks-department maturity more than population scale.

Several of these states fall outside the absolute top-10 entirely, which is the point of normalizing. Wisconsin has fewer than a fifth as many verified pads as Texas, but Wisconsin families on average live closer to a pad. The same logic applies up and down the rankings: the District of Columbia leads the entire country on per-capita coverage despite a small absolute count, while California and New York rank below average on per-capita because their populations dwarf their pad networks even at strong absolute counts.

• 1. Wisconsin — rank 9
• 2. Iowa — rank 10
• 3. Nebraska — rank 6
• 4. Kansas — rank 7
• 5. Minnesota — rank 15
• 6. Oklahoma — rank 12
• 7. Indiana — rank 11
• 8. Ohio — rank 8
• 9. North Dakota — rank 2
• 10. South Dakota — rank 3

Eight states sit below 50 verified splash pads in the April 2026 snapshot: West Virginia, Mississippi, Arkansas, Alaska, Wyoming, Montana, Idaho, and New Mexico. This is not necessarily a story of municipal under-investment. Population density and settlement patterns explain a meaningful share of the gap — Wyoming and Alaska have the lowest population densities in the country, and pads tend to follow population. Mississippi and West Virginia have a different pattern: comparable density to several mid-tier states, but historically lower per-capita parks-department capital budgets.

The gap also reflects documentation, not just capital. Several of the listed states have rural municipal pads that do not appear on operator-published web pages, which keeps them out of the verified count even when local journalism confirms their existence. We treat this as a research backlog rather than a coverage verdict, and the gap states are prioritized for proactive partnership outreach in the 2027 cycle. A pad confirmed by phone with a municipal recreation office and corroborated against a secondary source can clear verification within a single editor cycle.

• West Virginia — 30 – 40
• Mississippi — 55 – 65
• Arkansas — 60 – 75
• Alaska — 15 – 22
• Wyoming — 15 – 20
• Montana — 25 – 35
• Idaho — 45 – 55
• New Mexico — 65 – 75

Climate predicts coverage scale more cleanly than wealth or population alone. Heat-driven states — Texas, Arizona, Florida, Georgia, Nevada — operate the longest seasons (220 to 320+ days) and run the largest summer-only pad networks in absolute terms. The operating-day curve gives Sun Belt pads roughly 2x to 3x the annual run hours of their New England counterparts and improves the cost-per-visit math that drives municipal capital approval.

Northern states tell a different story. Wisconsin, Minnesota, and Maine run shorter seasons (110 to 145 days) but invest in higher per-pad capital budgets, which shows up in the accessibility, shade-structure, and rest-seating dimensions of the 2026 audit. The cooler-climate top tier — Madison, Minneapolis, Portland OR, Pittsburgh — produces the strongest accessibility scores in the country despite a fraction of the operating calendar. Hot-climate metros tend to optimize for raw pad count and seasonal throughput; cold-climate metros tend to optimize for per-pad depth.

The pattern is a tendency rather than a verdict. Several Sun Belt metros operate individual flagship pads that match anything in the cool-climate top tier, and several cool-climate states sit near the bottom of the per-capita ranks despite strong per-pad quality. Climate explains the shape of the curve; civic intent explains where each state actually lands on it.

Roughly 78% of verified splash pads in the April 2026 snapshot are free to the public. The free share clears 90% in much of the heartland and Northeast — Wisconsin, Iowa, Maine, Vermont, the Dakotas, New Hampshire, and Rhode Island all post free shares above 90%. This is the single most underreported fact in national coverage of public water amenities: a splash pad is, in practice, the most universally free water-play option in America.

Paid concentration sits in two clusters. The first is vacation states where shore counties or destination parks fold a small admission fee into a regional park entry — New Jersey leads here at roughly 38% paid, driven by shore-county districts. Florida and California come next, with paid shares around 26-29% concentrated in tourism-corridor regional parks rather than neighborhood pads. The second cluster is private-resort tie-ins, which we exclude from the directory entirely; a hotel-side spray feature sold to non-guests for a day-pass fee is the only resort case that meets our public-access definition, and even those are a tiny share of the paid total.

Regionally, the Northeast and the Midwest run the highest free shares, the Southeast and Sun Belt run mid-range shares, and the Mid-Atlantic shore counties pull the national average down. A family searching for free water play has a roughly four-in-five chance of finding it at any verified pad in the directory.

The 2026 100-pad accessibility audit surfaced clear regional patterns that map onto the state-level benchmarks here. The Northeast leads on documented accessibility coverage, anchored by Massachusetts, New York, Pennsylvania, and the New England states that consistently publish per-pad accessibility statements. The Mid-Atlantic and Pacific Northwest follow close behind, with Maryland, Virginia, Washington, and Oregon scoring above the national average on companion-seat presence and approach-path quality.

The Southeast and Southwest cluster at the lagging end. Several of the Sun Belt metros with the largest absolute pad counts post the weakest accessibility coverage, particularly on companion-seat placement, family changing rooms, and access-aisle paint. The gap is rarely a budget story — most of the audit's high-impact accessibility additions cost under $2,000 per pad — and more often a documentation and design-review story. States with embedded accessibility consultants in capital planning consistently outperform states with comparable budgets that lack the same review discipline.

The accessibility tier in the full state table below summarizes each state's audit cluster and known parks-department documentation practice. "Limited data" indicates fewer than five audited or desk-verified pads in the underlying audit sample — primarily the rural, low-density states already flagged in the coverage-gaps section.

Per-state coverage totals, free-versus-paid splits, and accessibility tiers are published as open data alongside the daily directory snapshot. The state-stats endpoint is regenerated every 24 hours from the live directory, and the underlying pad-level data flows from the same source-priority pipeline described in the editorial methodology.
