On August 9, the transient docks in downtown Petaluma's Turning Basin reopened to boaters after a short closure. The city had shut them down August 5 through 8 to install a fire suppression system, the last item on a punch list that had been open, in one form or another, since 2022. Boats could tie up again in front of the Yacht Club. Paddlers could launch from Weller Street without dodging construction equipment. For a lot of people who live near the water, that felt like the river was finally done being a project.
It isn't. The docks are a different job from the riverbed underneath them, and the harder of the two hasn't been finished.
Two Different Finish Lines
The dock replacement and the dredging are separate contracts with separate timelines, and it's easy to mix them up because they've been running on parallel tracks through the same stretch of water. The docks were pulled out in 2022 to clear the way for dredging equipment. New concrete floats were fabricated by the end of 2023 and installed during 2024's approved construction window. What closed the loop this August was the fire suppression system, a code requirement that had nothing to do with silt.
The dredging is a different animal entirely, run by the U.S. Army Corps of Engineers rather than the city, and it started later. Crews mobilized on October 8, 2025, and by mid-November they had pulled somewhere between 77,000 and 89,000 cubic yards of sediment out of the channel, a pace of roughly 3,000 cubic yards a day. That's real progress. It's also short of what the 2020 dredge removed in about six weeks: more than 200,000 cubic yards, at a cost of $9.7 million, ending a stretch when the river hadn't been properly dredged since 2003. This year's project carries a budget in the neighborhood of $7 million or more. Measured against the last full-scale effort, the fall 2025 season did less work for a comparable price tag, and the reason has to do with where the crews started.
Why the Busiest Stretch Got Saved for Last
Dredging crews don't start at the Turning Basin. They start at the southern end near San Pablo Bay and work their way north, because that's the order that lets them dredge up to the more impacted stretches, including the Turning Basin itself, once the rest of the channel is clear. It's a sensible sequence for the contractor. It also means the part of the river that Petalumans actually see every day, the water in front of River Plaza and the Yacht Club and the restaurants along the basin, is the last thing to get touched.
By the time the federally regulated work window closed on November 30, 2025, that sequence hadn't finished. The city's own project update from that November said as much: the Turning Basin might not get dredged this season, and crews would look at a return the following fall to close it out. That's this fall. As of Labor Day, the city hadn't posted a firm start date for that return, which means the busiest, most visible, most silted stretch of the Petaluma River is currently sitting exactly where it was left in November, waiting for a work window that hasn't been announced yet.
There's a reason dredging happens on this schedule at all. Fall is when salmon and other migratory fish have finished their spawning runs, so a cutter-suction dredge working around the clock does less damage to the ecosystem than it would in spring or summer. The same environmental logic that governed the pile driving for the new docks, which also had to work around marine life protection windows in the tidal slough, governs when the Corps can be out there with a dredge. The river doesn't get fixed on a construction schedule. It gets fixed on a fish schedule, and that's part of why patience with this particular project has always been the more reasonable position.
A History That Makes the Wait Familiar
None of this is new for people who've watched the river for a while. The Army Corps stopped dredging the Turning Basin after 2003 because the economics stopped working: the cost per cubic yard climbed from around a dollar to somewhere between $25 and $30, and the Corps downgraded the river's priority relative to other waterways. That left Petaluma without a proper dredge for 17 years, until the 2020 project finally cleared it out. Local boaters still remember the years of running aground twice a day and joking about the mudflat locals called Duck Island.
The pattern since then has been progress in stages rather than one clean resolution. Docks removed. Docks rebuilt in pieces. A dredging contract that got most of the channel but not the basin. A second season now on the calendar without a confirmed date. If you're used to thinking about infrastructure projects as things that either happen or don't, the Turning Basin is a better example of something that happens in layers, and the layer that matters most to downtown, the part right in front of the businesses that depend on foot traffic and boat traffic, is consistently the one still in progress.
What's Actually Open Right Now
The practical answer, as of this September: the docks are open to all users including motorized vessels, day use and overnight berthing are available first come first served, and the D Street Bridge is back to its normal opening request process rather than the "go up, go down" schedule the Corps used during active dredging last fall. What isn't resolved is whether boats will see another round of bridge disruption once dredging equipment returns for the Turning Basin, and there's no public timeline yet for when that starts.
The Fall Calendar On the Water
A few dates on the water this season are worth having on hand. The 2026 Petaluma River Craft Beer Festival runs September 12. Santa's Riverboat Arrival is set for November 28, one of the events the city specifically said would go on as scheduled regardless of how the dredging shakes out, alongside the Lighted Boat Parade later in the season. Both are the kind of river tradition that survives construction delays because they don't depend on the channel being fully clear, just navigable enough for a boat with lights on it.
The Wharf Changed While No One Was Watching
A few blocks from the basin, on the west side of downtown, Foundry Wharf has quietly turned over one of its longest-running tenants. The 1908 engine works building has housed Sonoma Portworks since 2003, when founder Bill Reading expanded his fortified wine operation there and added a tasting room in 2007. Bill and his wife Caryn recently retired and sold the business to Heringer Family Estates, third-generation grape growers out of Clarksburg who had long supplied Portworks with fruit. The space is now Portworks Wine Lounge, and it still pours the same ports, made by longtime winemaker Deneice Knotts, who turns out up to 1,000 cases a year across ten fortified wines plus a hazelnut sherry and a fig liqueur. What's new is Heringer's own organically farmed table wine from Clarksburg, added to the lineup alongside the ports. The tasting room itself hasn't changed much: the corrugated bar, the barrel-hoop artwork Bill Reading made himself, the solera system for the Maduro tawny port still visible behind the curtain if you look. Aqus Cafe and Petaluma Coffee & Tea remain the anchors for anyone using the wharf as a coffee stop before or after a walk along the river.
It's a small piece of the same larger pattern. The building didn't get demolished and rebuilt. It got handed to someone new who kept most of what worked and layered something else on top, which is a decent description of how most of downtown Petaluma's waterfront has evolved for the last few years, one incomplete project and one quiet handoff at a time.
If you're the kind of person who tracks projects like the Turning Basin dredge because you live close enough to the water to care when the bridge goes up, or because you're weighing whether that closeness to the river is worth it for wherever you land next in Petaluma, that's exactly the kind of local detail Cozza Team pays attention to on behalf of clients throughout Sonoma County.
