Walk the Interurban Trail south from Fairhaven Park this week and you will cross a bridge that spent the better part of a year as a working construction site, a spill zone, and finally a fish passage that the city says is doing exactly what it was built to do. Water moves under two new arch culverts at 12th and 14th Streets. Salmon have been spotted upstream of the project, which the city takes as proof the fish can get past the new structures. The trail is open end to end for the first time since last year.
That is the version of the story most people in South Bellingham already know in outline. What's easy to miss, because the closures and reopenings happened in pieces over more than a year, is that the fix and the failure happened on top of each other. The same project meant to protect Padden Creek's fish run is the one that put diesel into it.
What actually reopened in February
The city's project page for Padden Creek at 12th and 14th Streets lays out the technical win plainly: in-water work finished in the fall, both new fish-friendly arch culverts are flowing freely, and crews added large woody debris to the creek to stabilize the banks and create habitat. Salmon have already been seen upstream of the site, which the city treats as confirmation that the culverts do their job.
For residents, the visible version of that milestone came earlier, in late February, when the section of the Interurban Trail that had been closed for nearly eight months finally reopened. That closure had displaced the ordinary rhythm of the corridor for anyone who uses it to get from Fairhaven to Larrabee State Park, or just to walk a dog on a Tuesday. The city marked the reopening with a guided tour in late April, timed to let people see the finished culverts up close rather than just read a press release about them.
So the trail has been open since February. The culverts have been validated by an actual salmon run since roughly the same window. Two different kinds of "done," landing close enough together that most people experienced them as one event.
The spill that almost undid the point of the project
Here is the part that gets lost in a simple reopening story. In August of last year, a faulty pump powering a bypass system at the 12th Street construction site leaked diesel into Padden Creek twice in the same week, four days apart. The Washington Department of Ecology estimated 344 gallons in the first release and 332 gallons in the second, a combined total of roughly 676 gallons, in a creek the project existed to protect.
A Unified Command formed to handle it: the Department of Ecology as lead agency, the City of Bellingham, the Lummi Nation, the Nooksack Indian Tribe, and Faber Construction, the contractor building the culverts. Crews deployed twenty to thirty sets of floating boom near the mouth of the creek to keep the diesel out of Padden Estuary and Bellingham Bay, and by most accounts it worked. No fuel reached the bay. The city's early count of fish deaths, seven, was later revised down to two, though responders noted that public reports of dead fish don't always match what crews are actually able to recover.
By late August, sediment sampling had come back below detection levels and a Shoreline Cleanup and Assessment Technique team walked the site one final time to confirm no recoverable fuel remained. Work shifted from emergency response to restoration and long-term monitoring, and Faber Construction got the green light to resume the original culvert project it had been hired to finish in the first place.
That is a fast, well-documented recovery by any standard. What hasn't closed out, at least not as of the city's most recent public update, is who pays for it. The Department of Ecology's own project notes still describe an open investigation to determine which party or parties are responsible for the cleanup costs. The trail reopened. The salmon came back. The bill is still being sorted out.
That loose thread matters less for what it changes about your Tuesday walk and more for what it tells you about how these projects actually run in this neighborhood. A creek restoration meant to make Padden Creek more passable for Chinook and other salmon runs came within one bad pump seal of setting that goal back, and the paperwork on who's accountable for that near-miss is still open, months after the spill itself. Good outcomes here take longer to fully settle than the ribbon-cutting suggests.
The detour that stuck
While the main trail was closed, the practical question for anyone who walks this corridor daily wasn't abstract. It was: where do you go instead. For a lot of South Bellingham residents, the answer turned out to be Hoag's Pond and the surrounding forest known locally as Hundred Acre Wood, tucked just east of the Interurban Trail near 24th Street.
It's a small piece of ground with an outsized history. The city assembled the roughly 112 acres that now make up Fairhaven Park and its surrounding forest over decades, starting with an 82-acre purchase from Washington Federal Bank in 2011 after two separate proposals to build more than a thousand homes on the land failed to clear the city's planning review. Hoag's Pond itself, a small forested pond fed by runoff from the higher ground around it, was added to that footprint in 1999. The loop trail around it runs about four-tenths of a mile, easily walkable, and connects into the same Chuckanut Community Forest network as the main Interurban corridor.
None of that is new information to longtime residents who already knew the pond was there. What's changed is how many people now treat it as a real alternative rather than a side trip. A closure that displaced foot traffic for eight months gave a lot of walkers and dog owners a reason to try the quieter loop, and there's no obvious reason that habit reverses itself now that the main trail is open again. If you found Hoag's Pond for the first time last year because the Interurban was blocked at 12th Street, you're not alone, and you don't need the detour excuse anymore to justify going back.
Before the spray park closes
There's a practical reason to get out on this stretch of trail this particular week rather than sometime next month. Fairhaven Park's spray park, the splash area next to the playground that families lean on all summer, runs on a fixed seasonal schedule set by the city: open June 15 through September 15, 11 a.m. to 7 p.m. daily. That window closes tomorrow.
It's a small detail, but it's the kind of thing that only matters if you already live close enough to Fairhaven Park to plan a Monday around it. If a walk down the reconnected Interurban Trail, a loop past Hoag's Pond, and a last afternoon at the spray park sounds like a reasonable way to spend the last day before the fall shift sets in, this is the day.
The larger point underneath all of it: a fish passage project, a diesel spill, a Unified Command response involving two tribal governments and a state agency, and an unresolved question about who covers the cost. That's not a minor maintenance story. It's a fair measure of how carefully this particular stretch of South Bellingham gets watched, by the city, by the tribes with fishing rights on this water, and by the neighbors who noticed when their regular walk disappeared for the better part of a year.
If you're the kind of person who tracks these details because you already live along this creek, you already know why they matter. If you're new to the neighborhood, or thinking about it, it's worth understanding that South Bellingham runs on this kind of close local attention long before it shows up in a listing description.
Julian & Company is a Bellingham team that pays attention to these details because we live among them too. If you're weighing a move to South Bellingham, or wondering what a home near this stretch of Padden Creek is actually worth once you factor in what makes the neighborhood work day to day, reach out to Julian & Company and start the conversation.
