What our four tiers actually mean

A binary "ADA-accessible: yes or no" flag is the convention across most directories, and it misses real differences that families plan trips around. A pad with a paved path and a ground-level entry is technically accessible. A pad with a paved path, a line-of-sight companion seat, a quiet zone, a family changing room, Braille signage, and scheduled sensory hours is also technically accessible. To a wheelchair-using caregiver of a non-verbal autistic child, those two pads are not the same trip.

The four-tier system communicates a gradient. Tier 1 says "physically reachable." Tier 4 says "designed for inclusion across mobility, sensory, visual, hearing, and caregiver dimensions." Tiers 2 and 3 mark the meaningful ground in between. The point is not to grade parks departments but to give families a planning vocabulary that matches their actual experience, and to give parks departments a roadmap from "we built a pad and a path" to "we built a pad that any disabled child can use."

The tiers are cumulative. Tier 3 includes everything in Tier 2 and Tier 1; Tier 4 includes everything below it. A pad cannot leapfrog tiers. A pad that has Braille signage but no companion seat with line-of-sight does not qualify for Tier 4, because the foundational physical inclusion is missing. The cumulative structure is what makes the rating a planning tool rather than a feature checklist.

Paved path to the splash zone, ground-level entry, no steps. The minimum bar.

Tier 1 describes a pad that a wheelchair user, a stroller, or a caregiver with a mobility device can physically reach and enter. The defining conditions are a paved or firm-stable approach path that runs end-to-end from the parking access aisle to the spray surface, a ground-level spray entry with no steps or lip, and a path width consistent with ADA Chapter 4 guidance. Many splash pads in the directory meet only Tier 1, and that is meaningful — twenty years ago, even reaching the pad was not a given.

Tier 1 is a floor, not a ceiling. A pad that meets only Tier 1 may still leave a wheelchair-using caregiver without a place to sit, a sensory-sensitive child without a quiet retreat, or a non-verbal child without legible signage. Treating Tier 1 as full accessibility is the binary trap that the four-tier system is designed to avoid. The directory marks Tier 1 honestly, neither inflating it into a higher rating nor dismissing it as inadequate when it is the most a parks department has so far built.

Tier 1 plus companion seat in line-of-sight, slip-resistant surface, accessible restroom within 200 feet, and van-accessible parking.

Tier 2 takes Tier 1 and addresses the rest of the physical visit. The defining conditions are an ADA companion seat with a direct line-of-sight to the central play zone (placement matters as much as presence), a slip-resistant play surface compliant with the relevant state code, an accessible restroom within roughly 200 feet of the pad with a roll-in stall and grab bars, and a parking area with a van-accessible space and an unblocked access aisle. A pad that meets only Tier 1 reaches the spray; a pad that meets Tier 2 supports a full visit.

The line-of-sight requirement on the companion seat is the single most under-appreciated detail in the rubric. The 2026 audit found that 71% of pads had a companion seat present, but only 41% sat with a direct line-of-sight to the play zone. A caregiver who must turn or stand to supervise loses the autonomy benefit that the seat is supposed to provide. Tier 2 captures that distinction explicitly so that placement, not just procurement, is held accountable.

Tier 2 plus a designated quiet or sensory zone or scheduled quiet hours, a low-spray mode option, a gradient of stimulation, and signage with photos and large print.

Tier 3 expands the rubric beyond mobility. The defining conditions are a designated quiet or sensory zone within or adjacent to the pad (or, equivalently, a posted weekly quiet hour with reduced spray volume), a low-spray mode option on the controller, a gradient of stimulation that lets a sensory-sensitive child step in and out of intensity rather than face an all-or-nothing spray, and signage that uses photographs, pictograms, and large print rather than relying on dense text. Tier 3 is where the rubric starts to serve children with autism, sensory processing differences, anxiety, and cognitive disabilities.

The 2026 audit identified the sensory or quiet zone as the weakest dimension across the directory at 12% — and also one of the cheapest to add. A reduced-spray weekly hour costs a sign and a controller adjustment. Photographic signage is a one-time print job. Tier 3 is rated rigorously precisely because it is achievable, low-cost, and meaningfully expands which children can use the pad without a sensory overload event.

Tier 3 plus Braille signage, audio cues for non-visual users, scheduled sensory-friendly hours, family changing room, accessible water bottle filler, and designated shaded quiet seating.

Tier 4 is the gold-standard rating and is given sparingly. The defining conditions are Braille and tactile signage on rules and wayfinding, audio cues or announcements for non-visual users, regularly scheduled sensory-friendly hours promoted on the operator's website, a family or companion changing room (not just a single accessible stall) sized for an older disabled child and a caregiver, a water bottle filler at a reachable height for a seated user, and designated quiet seating with shade and a clear sight line to play. Tier 4 reflects a pad that has been designed across mobility, sensory, visual, hearing, and caregiver-ergonomic dimensions in concert.

Tier 4 is rare. The 2026 audit found that fewer than one in ten audited pads carried Braille or tactile signage, and audio cues were the lowest-scoring single dimension at 9%. A Tier 4 rating typically requires a parks department that has embedded an accessibility consultant in design review, retrofitted older pads alongside new construction, and treated multi-disability inclusion as a budgeted line rather than a discretionary add. The directory rates Tier 4 conservatively because the rating is a planning signal, not a marketing badge.

Every tier rating is sourced and dated. The tier appears on the pad page next to a last-verified timestamp, the editor handle that signed the record, and a link to the documentary basis: an operator-published accessibility statement, a city open-data feature attribute, photographed evidence, or a combination. Where the operator publishes a formal accessibility statement, the pad page links to it directly. Where photographs are the basis, the photographs are captioned with the date and the source.

Owner confirmation is solicited wherever possible. Parks departments are emailed when a pad is being rated for the first time and asked to confirm or correct the proposed tier; a parks-department confirmation is recorded as the strongest single source of truth. Where a department does not respond, the rating is published with the available evidence and the field is marked as desk-verified rather than owner-confirmed.

Re-verification follows the directory's standard cadence. Every pad is re-checked at least twice a year against the season-change pulse described in the editorial methodology, and any community report through the corrections channel triggers an immediate re-verification of the tier. The full process — source priority, three-pass verification, conflict resolution, and errata — is documented at /methodology.

The tier rating describes the built environment and the operator's published policies. It does not describe staffing, on-site behavior support, communication boards, AAC support, weather-event accommodations, lifeguard-style assistance, or the willingness of any individual staff member on any given day to adjust spray volume on request. Those vary by visit and are outside the scope of a directory listing.

A Tier 4 pad is not a guarantee that a particular visit will be sensory-friendly. The rating is a structural promise, not an operational one. Families with specific clinical needs — for example, a child requiring an AAC device, a service animal accommodation, or a medical-device-friendly changing space — should call the parks department before a first visit to confirm that the operational details match the household's needs.

The directory also does not promise compliance with any specific standard beyond what each tier defines. The four-tier system draws on the ADA 2010 Standards and the federal Outdoor Developed Areas guidelines as inputs but is its own framework. Parks departments evaluating their pads against formal Title II self-evaluation should treat the tiers as a complementary planning tool, not as a substitute for legal compliance review.

The four tiers map onto practical pre-visit decisions. Tier 1 is a check-and-go: confirm the path is clear of construction or seasonal damage and proceed. Tier 2 is worth a phone call about the restroom — accessible restrooms within 200 feet are the most-cited mid-visit failure point in parent reports, and a quick confirmation that the restroom is open and unlocked saves a long detour mid-meltdown.

Tier 3 warrants checking the parks-department site or calling for the current sensory-friendly schedule, because quiet hours move with summer programming and the directory captures the most recent published schedule rather than the daily one. Tier 4 should be treated as a gold-standard match for households with multi-disability needs but still verified pre-visit on the specific dimensions that matter to that household — Braille signage, family changing room dimensions, AAC accommodations, and scheduled hours.

Across all tiers, the directory's commitment is that the rating reflects the most recent verified evidence. A pad's tier can change between visits if the operator removes a feature, retires a quiet hour, or rebuilds a section; the changelog logs every tier change with a date and a source. Families relying on a tier for a planned visit are encouraged to check the pad page within a week of the trip rather than relying on a months-old screenshot.

Tier ratings are a public record and they are correctable. If a family's lived experience does not match the published tier — a Tier 3 pad whose quiet hour is not actually posted, a Tier 2 companion seat that no longer faces the play zone after a refurbishment, a Tier 4 family changing room that has been converted to storage — the correction can be filed at /submit. No account or signup is required, and the submitter's identity is never published.

Confirmed corrections are reflected in the directory within 48 hours of verification, and the change is logged in the public changelog with the prior tier, the new tier, the source that triggered the change, and the date. Where a parks department contests a correction, the disagreement and its resolution are both recorded so readers can audit how the tier was established. The tier is a living rating, not a frozen one.
