Every council vote in Redondo Beach eventually gets read as a verdict. Last week's 5-0 decision on Seaside Lagoon is already being talked about that way around King Harbor: the city said no to the wave pool, yes to the rehab, and now the aging lagoon at 200 Portofino Way is finally getting fixed. That version fits neatly into a headline. It also skips the part of the story that actually matters if you live near the harbor and plan to use that lagoon again.
What the council did on September 15 was authorize staff to file paperwork. Specifically, a Coastal Development Permit application to the California Coastal Commission, the state body that has final say over anything built on Seaside Lagoon's tidelands. The city cannot approve its own project there. It can only ask permission. Mayor Jim Light was careful about this distinction after the vote, calling it the closest the city has come to construction in the two decades residents have been asking for a fix, while acknowledging the decision was still just a step, not a finish line.
That distinction is the whole story. Here's what's actually settled, what's still open, and why the lagoon you picture in 2027 might not be the one that gets built.
Why the Lap Pool Disappeared
If you've watched the Seaside Lagoon conversation over the past two years, you probably remember an early version of the plan that included both a recreational lagoon and a separate lap pool. That version is gone, and the reason is a regulatory one most residents never heard about: Los Angeles County Public Health determined the two water features would need to be physically separated with their own filtration systems if they operated side by side. That single requirement pushed the combined project's estimated cost past $16 million, which is well beyond what the city's funding could cover.
So the lap pool got cut, and Phase 1 shrank to a single recirculating lagoon.
| Original combined concept | Current Phase 1 design | |
|---|---|---|
| Water features | Recreational lagoon plus separate lap pool | Recreational lagoon only |
| Filtration | Two separate systems required | One recirculating system, roughly 770,000 gallons at 3,000 gallons per minute |
| Depth | Lap pool required standard swim depth | Up to 5 feet, sand-covered zero-depth entry into a concrete-bottom section |
| Estimated cost | Over $16 million | Staff estimates have ranged from roughly $9.47 million to $11 million |
The design that survived keeps the sand entry and the slide people associate with the lagoon today, but trades the flow-through seawater system, the one that pulls water from outside the breakwater, chlorinates it, then de-chlorinates it back into the harbor, for a closed recirculating loop. That system is the actual fix for the money problem: the old intake and discharge model is what has been generating the water-quality fines.
The Numbers Behind Why This Kept Getting Punted
Redondo Beach's own waterfront director, Elizabeth House, laid out the financial case at the September 15 meeting. The lagoon was open 104 days this year and drew more than 67,000 admissions, bringing in close to $780,000 in gate and rental fees. That's real revenue for a city-run amenity. It's also revenue that's been getting eaten by the cost of keeping an 80-plus-year-old delivery system running.
- Water-quality fines over the most recent two-year cycle: $175,000
- Repair cost after a 2025 pump failure that shut the lagoon down for about two weeks: $60,000
- Projected construction start for the Phase 1 rebuild: April 2027
- Projected construction duration: roughly 10 months, targeting completion before the May 2028 BeachLife Festival and the 2028 Olympics
Those dates depend entirely on how quickly the Coastal Commission moves. The council's vote didn't lock in April 2027. It started the clock on the review that has to happen before anyone can promise that date.
The Compliance Question Nobody's Fighting About in Public Yet
There's a second open thread that hasn't made it into most of the coverage: whether the current design actually satisfies Measure C, the voter-approved measure that governs what can happen to Seaside Lagoon. Measure C doesn't just allow renovation. It requires that any replacement function as an equivalent public facility, matching the existing water surface area, beach, and amenities, and it explicitly bars turning the lagoon into open water connected to the harbor.
At least one council member involved in drafting Measure C has already pushed back on an earlier version of the design, pointing out that eliminating a lanai structure from the plans didn't meet the measure's standard. That change has since been restored. It's a small detail, but it's a preview of the kind of scrutiny this project will face again once it reaches the Coastal Commission, which will be reviewing the same equivalence question with legal authority to send the design back.
Where the Wave Pool Idea Actually Came From
The wave pool didn't emerge from a city planning process. It surfaced at a Harbor Commission meeting in late August, pitched by Allen Sanford, co-founder of BeachLife Festival and the California Surf Club, under the name Ocean Park. The concept would have shrunk the public swimming lagoon and added a compact wave-generating facility with surf sessions priced in the range of $100 to $150 an hour, run as a concession with a share of revenue going back to the city.
Mayor Light addressed the confusion directly in a Facebook post before the vote, explaining that the city legally couldn't hand a concession like that to one company without a competitive process, and that ultimate jurisdiction over anything built at Seaside Lagoon belongs to the Coastal Commission regardless of what the city council prefers. City records also show the council had been holding closed-session real estate discussions with Sanford and BeachLife about unrelated harbor property, the marina parking lot among it, months before the wave pool concept ever came up. Those talks predate the current debate and aren't tied to it, but they're a reminder that the city's relationship with BeachLife's organizers runs on more than one track.
The Harbor Commission voted only to receive and file Sanford's presentation, not to endorse it. The council's September 15 vote didn't reject a wave pool either. It simply declined to pause the existing rehab plan while a competing concept got vetted, which is a different thing than saying no forever.
What This Summer Already Told Us About Demand
Whatever gets built, the lagoon's site has already shown this year how much programming pressure the harbor can absorb. BeachLife Festival returned to Seaside Lagoon for three days in May. Then Ride the Tide, an independently produced World Cup viewing event unaffiliated with FIFA, ran for 38 straight days at the same site from June 11 through July 19, overlapping with the pier's Thursday and Saturday summer concert series for a stretch in early July. Residents who tried to park near Fisherman's Wharf on a Thursday evening that month already felt what happens when a match-viewing crowd, a free concert crowd, and normal harbor dinner traffic land on the same structures at once.
That's the backdrop for why this rehab matters beyond just fixing an old pump. Seaside Lagoon isn't a quiet corner of the harbor anymore. It's becoming the anchor for multi-week events, and whatever design comes out of the Coastal Commission process will have to hold up to that kind of use, not just a Tuesday afternoon in July.
What Actually Changes for You
If you live near King Harbor, here's the version worth remembering: nothing gets poured into the ground before spring 2027 at the earliest, and even that date holds only if the Coastal Commission clears the permit without requiring design changes. The lap pool is gone. The wave pool isn't dead, just set aside while the city's own plan moves through a process it doesn't control. And the Measure C question, quiet for now, is exactly the kind of thing that resurfaces once state regulators start reading the fine print the same way a local council member already has.
The lagoon you picture reopening before the next BeachLife Festival might be the sand-entry version with the slide and the fountains. It might also look a little different by the time the Coastal Commission is done with it. Either way, the September 15 vote was the start of that conversation with the state, not the end of the one at home.
