How to convert a tired pool deck into a splash pad: a parks director's playbook

Why parks directors are looking at this

Across the US, hundreds of municipal pools built between the 1950s and 1980s are reaching end of life simultaneously. Liners are failing, mechanical systems need full replacement, and lifeguard hiring has gotten harder every year since 2020. The combined annual cost of running a small municipal pool now routinely exceeds $200K with attendance that has not recovered to pre-pandemic levels.

A splash pad on the same footprint can deliver more visits at a fraction of the operating cost, with no lifeguard requirement and a far simpler maintenance schedule. The math is increasingly hard to argue with, even for cities that loved their pools.

This is the playbook for doing it right, drawn from recent retrofits in three midsized US cities.

Phase 1: the honest pool assessment (months 1-3)

Before you commit to conversion, get a structural and mechanical assessment from an independent aquatic engineering firm. Three questions matter:

1. Is the existing pool shell salvageable as a recirculation surge tank? If yes, you save $80K to $200K.

2. Is the deck structurally sound for new feature anchors and slope adjustments? If not, full deck replacement is required.

3. What does the existing service utility (water, sanitary, electrical) need to support a modern splash pad?

The answers shape budget more than any other decision. Expect to spend $15K to $30K on the assessment alone. Worth every dollar.

Phase 2: public consultation (months 3-7)

Skip this phase and the project dies. Communities form deep emotional attachments to their pools, even when the pool barely runs anymore. Three meetings minimum:

• Listening session. No designs. No conclusions. Just the assessment results and an open mic. Expect anger.
• Options workshop. Present three to five paths: full pool replacement (most expensive), pool-to-pad conversion, hybrid splash-and-shallow-pool, or close and consolidate.
• Preferred-option review. The preferred option, refined with community feedback, with renderings.

Recurring objections you will hear and need to answer:

• "Older kids and adults will lose their swimming spot." (True, partly. Address with regional pool access plans.)
• "Splash pads are just for toddlers." (Less true with modern themed designs. Show examples.)
• "We are giving up on the pool." (Reframe: you are giving the park back to the community at a lower operating cost.)
• "What about competitive swimming?" (Refer to nearest competitive pool. Be specific.)

The cities that get conversion right invest heavily in this phase. The cities that fail tried to skip it.

Phase 3: design and procurement (months 7-12)

Two procurement paths:

Design-bid-build: Traditional. The city hires an aquatic design firm, develops 100 percent construction documents, and bids construction separately. Slower but more competitive on price.

Design-build: A single vendor delivers design and construction. Faster (saves three to five months) but tends to come in higher and locks you into one vendor's feature catalog.

For a first-time conversion, design-bid-build is usually the safer route. For a city with a known good vendor and tight timeline, design-build can save a full season.

Critical design decisions in this phase:

• Recirculating vs single-pass (pick recirculating in 2026 unless rural with abundant water)
• Surface material (poured-in-place rubber for accessibility and cushion)
• Shade strategy (trees take years; sails or pavilions for immediate impact)
• Feature mix (split between toddler ground sprays and dump-bucket / arch features for older kids)
• Future expansion stub-outs (always cheaper to install during the original build)

Phase 4: construction (months 12-18)

A typical pool-to-pad conversion takes six to nine months on the ground. Sequence:

1. Demolition and selective salvage of existing pool elements

2. Mechanical and electrical rough-in for new pad systems

3. Surge tank conversion (if reusing pool shell) or new tank install

4. Deck reconstruction with appropriate slope to drains

5. Feature installation and plumbing connections

6. Surfacing application (poured-in-place rubber needs warm dry weather)

7. Commissioning, water-quality testing, and health-department sign-off

A spring construction start aimed at a Memorial Day ribbon-cutting the following year is the standard target.

Phase 5: budget reality

For a typical 3,000 to 5,000 square foot pool footprint conversion:

• Assessment and design: $50K to $120K
• Demolition and site prep: $80K to $180K
• Mechanical and surge tank: $150K to $350K
• Deck and surfacing: $100K to $250K
• Features and theming: $80K to $300K
• Permits, testing, contingency: $50K to $120K

Total range: roughly $510K to $1.32M for a mid-sized site, with the median project landing near $750K to $850K.

Funding stacks worth pursuing:

• General obligation parks bonds
• State conservation or recreation grants (varies by state)
• Land and Water Conservation Fund (federal)
• Joint funding from public health for cooling-center designation
• Private foundation grants for accessibility-focused builds
• Revenue diversion from the closed pool's operating budget

Phase 6: ribbon-cutting and the first season

A few things that consistently go right and wrong in opening seasons:

What goes right:

• Daily attendance two to four times higher than the closed pool's last season
• Operating cost roughly 60 to 80 percent below pool operations
• Stronger weekend programming partnerships with libraries and parks
• Real social media and word-of-mouth gravity that pulls families from neighboring jurisdictions

What needs attention:

• Crowd management on opening weekends (plan for double the design capacity)
• Sunscreen and water-safety messaging (bigger crowds, more first-timers)
• Restroom capacity (this is almost always the bottleneck)
• Shade gaps that did not show up in renderings (be ready to add temporary canopies)

What to tell the council before vote night

The successful pitch is not "splash pads are cheaper." It is "we can give this park back to the community as a year-of-life asset at a sustainable operating cost, accessible to more families than the pool ever was, with a faster path to ribbon-cutting than a full pool replacement."

Frame it that way and the conversion vote tends to land.
