South Coast Water District wants to put four desalination slant wells under Doheny State Beach's North Day Use Area. If the plan is approved, at least 121 of that lot's 694 parking spaces close for about two years, starting as early as next month. In the summer of 2027, the number of closed spaces goes up to 225. The California Coastal Commission takes up the change at its October 7 hearing, and staff are recommending approval with conditions.
For years, the Doheny Ocean Desalination Project was mostly a campground story. The latest plan moves the heavy work to the other side of San Juan Creek, into the lot with the main lifeguard tower, the visitor center, the aquarium, the showers and the grassy picnic areas. The Coastal Commission staff report calls this the most heavily used part of the park. It also says surfers are the most frequent visitors there.
Why the wells crossed the creek
Under the original permit, the wells were going in the campground. That was on purpose. An earlier version of the plan put wells in both places, and the Commission staff report says consolidating them in the campground "avoided coastal recreation and access impacts to the highly visited and heavily used NDUA."
Then the ground under the campground didn't cooperate. Newer geotechnical work showed that the wells there wouldn't hit sediments deep enough, wide enough or permeable enough to pull the roughly 10 million gallons of seawater a day the plant needs to produce 5 million gallons of drinking water. The better alluvial sediments turned out to sit farther west. The district looked at ways to keep the wellheads in the campground, but each one would have meant crossing under the existing SOCWA ocean outfall and putting it at risk.
So the wellheads go into below-grade concrete vaults at the east end of the North Day Use Area picnic area. From there, each well angles about 1,000 feet out to sea and ends 75 to 130 feet below the seafloor. The pipes to the treatment plant will be tunneled diagonally from the parking lot, under Pacific Coast Highway and San Juan Creek, so no open trench gets cut across the park. The water district says the stakes are local. Its service area imports roughly 90% of its water today.
The squeeze has a calendar
The staff report shows construction inside the state beach running from November 2026 through November 2028. The water district's own project page still says North Day Use Area work begins in October 2026, so the exact start depends on the hearing and the permit that follows. The fenced work area will grow and shrink as the job moves through its phases.
| Phase | Approximate window | Spaces unavailable out of 694 | ADA spaces affected |
|---|---|---|---|
| Baseline construction footprint | Full build, Nov 2026 to Nov 2028 | 121 | 7 |
| Microtunneling the conveyance pipelines | Feb to Sep 2027 | 208 | 7 |
| Peak pipeline installation | Jul to Sep 2027 | 225 | 7 |
The table only tells half the story. You also need to know how full the lot already gets. State Parks estimates the North Day Use Area runs 50% to 80% full from October to May. Holiday weekends and special events push it higher. Losing 121 spaces in November cuts into that cushion but leaves some room. Losing 225 spaces in July, August and September 2027 lands in the stretch when, by the Commission's own account, the lot "routinely reaches capacity." State Parks expects the lot to fill about twice as often during peak periods while construction is underway.
That makes summer 2027 the season to plan around. The first winter of construction should feel tighter than usual but workable. The second summer is when the lot will fill more often.
Events feel it too. About 12 of the 20 events planned at Doheny during 2026 and 2027 fall inside the construction window. For each one, the district has to either move the event or provide enough off-site parking and shuttle service to make up for every displaced space. This year's Ohana Festival ran September 25 through 27, before either start date. The Surf Queenie of Doheny contest is on Saturday, October 17, ahead of the staff report's November start, but within the October start on the district's page.
What stays open, and what comes back
The staff report says most of the North Day Use Area and its parking lot stay open to the public for the whole build. Pedestrian and bike routes will be signed and kept separate from equipment lanes. No beach areas are directly affected. The bike path will be restored after construction.
The space you'll lose besides parking is the grassy picnic area next to the main lifeguard tower. The staging area on the east side of the lot near San Juan Creek limits access to it. Under the district's proposal, once the wells are in it would restore that lawn with new landscaping, replace every pavilion it removed with new picnic tables and barbecue areas, and build a new restroom. Only one structure stays above ground for good, an electrical control building about 12 feet wide, 25 feet long and 10 feet tall, next to that new restroom.
The more useful promise for the next two years is Special Condition 17. It requires the district to write and carry out a Coastal Access Parking and Public Access Mitigation Plan, and the Commission's Executive Director has to approve it before the permit is issued. The plan has to:
- Designate seven ADA-accessible spaces inside the North Day Use Area to replace the seven displaced by construction
- Identify alternative parking for the peak periods when demand exceeds the reduced lot
- Spell out off-site access measures such as shuttles from remote parking, expanded City trolley service and drop-off zones within the North Day Use Area
The plan may also include extras such as discounted equipment rentals, so beachgoers don't have to drive their gear in. State Parks is running a visitation study on visit volume, dwell time and timing patterns to pin down when the shortfalls hit. The final plan hasn't been published yet.
The campground runs on its own clock
Moving the wells means the campground doesn't have to close for the desalination plant. It still has a closure coming for its own upgrade. State Parks says the campground stays open through at least the end of 2026, with a temporary closure expected sometime between 2027 and 2029. Since July 1, the booking window has been three months instead of six, so a night on October 1 opened for reservations on July 1.
The rebuild brings larger RV sites with full hookups, new tent-only areas, better pedestrian and bike circulation, new restrooms and a replacement interpretive area. It also raises the campground's grade and improves drainage. The district and State Parks plan to overlap the two construction periods to cut the total time the park is disrupted. South Coast Water District General Manager Rick Shintaku told the Orange County Register in May that pairing the work was a "win-win" because it could keep the campground from closing twice. While the campground is closed, the operating seasons at San Mateo and San Onofre Bluffs campgrounds have to be extended to give campers somewhere else to go.
Where to park when the north lot is full
Doheny's day-use fee is $15 per vehicle most of the year and $20 on weekends and holidays from Memorial Day weekend through Labor Day weekend. If you pay for an annual pass, check which one you have. Doheny accepts the California Explorer Vehicle Day Use Annual Pass, the Golden Bear Pass and the Distinguished Veteran Pass, among others. The Golden Poppy pass isn't valid at high-demand Southern California beaches like this one.
When the north lot fills, these are your fallbacks, roughly from closest to farthest:
- Puerto Place, next to the state beach, has hourly paid parking, though the harbor's parking page doesn't list the rate.
- The new Dana Point Harbor parking structure at 799 Harbor Way, at Golden Lantern and Dana Point Harbor Drive, gives you four free hours, then charges $6 an hour up to a $24 daily maximum. Special event rates may apply.
- Free street parking, which the harbor operator lists along Dana Point Harbor Drive east of Casitas Place, on Golden Lantern north of the harbor, along Dana Way, at Baby Beach and off Cove Road.
- Doheny's South Day Use Area, across the creek past the campground, is part of the same state beach. It has parking, beach access, restrooms and seasonal lifeguard towers.
- Capistrano Beach Park has surfing, bodysurfing, paddleboarding and fishing. OC Parks currently lists a maintenance closure on the southern part of its lot, with the rest of the parking open. County pay-and-display beaches charge $1 an hour, and a one-year pass costs $55, or $35 for seniors.
You can also skip the car. The pedestrian bridge over Coast Highway and the bike paths through the North Day Use Area link to the San Juan Creek Trail. The Park Lantern–Coast Highway bridge over the creek connects to the South Day Use Area and Capistrano Beach Park. An OCTA bus stop sits at the edge of the North Day Use Area at Dana Point Harbor Drive and Pacific Coast Highway. The City's free trolley stops there from Memorial Day to Labor Day, on September weekends and during special events. Expanded trolley service is one of the options the mitigation plan has to consider for the construction years.
For a hands-on way to spend time at the park as the work gets started, the Doheny State Beach Foundation has cleanups on Saturday, November 21, and Saturday, December 19.
