Grinding Asphalt Tonight, Quieter Trains Next Year: What's Actually Ending on Leucadia's 101

Tonight, crews are out on North Coast Highway 101 between Grandview Street and Jupiter Street, grinding and milling the westbound lane from roughly 8 p.m. to 11:30 p.m. The median lane stays open for southbound traffic. If you live anywhere near that stretch, you already know the drill: cones, a flagger, maybe a text alert from the Leucadia Streetscape Hotline. What you might not know is that this particular round of night work is closer to the end of a story than the middle of one, and a second, unrelated story just started its clock a few blocks away.

Most coverage of Leucadia's infrastructure treats these as two separate items. One is a drainage and sidewalk project that has been grinding through construction since 2024. The other is a federal rail safety grant that landed on August 19. Read separately, they're both mildly useful updates. Read together, they explain something more specific: after nearly two decades of parallel planning, the projects that will define daily life on this corridor are finally hitting real deadlines, and those deadlines happen to fall in the same twelve-month window.

Two Plans Born the Same Year, Funded Eighteen Years Apart

The Leucadia Streetscape project and the Verdi Avenue undercrossing share an origin story. Both trace back to 2008, when the city first sketched out a vision for the 2.5-mile stretch of Coast Highway 101 running through Leucadia, and separately identified Verdi as a spot where pedestrians and cyclists needed a safer way to cross the tracks. From there, their paths diverged for most of two decades.

The Streetscape project got its first construction contract in the fall of 2020. Earlier segments, from Marcheta Street to Basil Street and again from Basil Street to La Costa Avenue, brought new striping, pedestrian crossings, and dedicated bike lanes that are already in daily use. The current phase, Segment C West, combined with the North Coast Highway 101 Drainage Improvements, began construction in March 2024 and is now targeting completion in late summer to fall 2026, according to the city's most recent update to council on August 26.

The Verdi undercrossing sat on a wish list for most of that same period. Two other undercrossings, at Santa Fe Drive and El Portal Street, were built in 2013 and 2022. Verdi kept getting identified, designed, and shelved for lack of a funding source. That changed on August 19, when the Federal Railroad Administration awarded Encinitas up to $33.6 million through its Federal-State Partnership for Intercity Passenger Rail Program, the same national funding round that sent $124.4 million to SANDAG for improvements across the county's Pacific Surfliner corridor.

What the Federal Money Actually Buys

The grant covers more than the undercrossing. It funds a package of crossings and gates along roughly six miles of the LOSSAN rail corridor that runs through the city.

Deputy Mayor Jim O'Hara, who lobbied for the grant, called it a win for public safety and mobility. Mayor Bruce Ehlers described it as a major step forward for the community. Neither statement is surprising on its own, but the design timeline underneath it is worth sitting with. The quiet zone piece, which stops trains from sounding their horns at every crossing, is the closest to being ready to build. The Verdi undercrossing already has Planning Commission approval. The two newer at-grade crossings at Grandview and Phoebe are the furthest behind, at roughly a third of the way through design work. That means the corridor is heading into a period where some rail-adjacent noise could ease before the construction needed to build the rest of the crossings even starts.

Encinitas will cover 20 percent of the cost as a local match, standard for this kind of federal partnership program.

The Streetscape's Own Deadline Problem

While the rail grant is brand new, the Streetscape project has been racing a different kind of clock all year. In May 2022, the city borrowed $20 million from the California Infrastructure and Economic Development Bank to help fund Segment C West, and that loan comes with a spending deadline of December 2026. That deadline is likely why the city has spent 2026 amending its consultant contracts rather than letting the project drift. On March 19, council approved an amendment to the Psomas construction management agreement, and on April 22 it approved a similar amendment for Michael Baker International's civil engineering support, both explicitly framed as extending services to match the construction duration that grew longer than originally planned.

The construction team itself is a small roster of names residents will start recognizing if they don't already. Blue Pacific Engineering & Construction holds the main $20.25 million construction contract. Psomas handles inspection and public outreach. Michael Baker International does the roadway design. Peltz and Associates handles landscape design, which matters here because part of the plan is restoring Leucadia's tree canopy with 101 new trees along the corridor.

The drainage work exists because Leucadia has a flooding problem that predates most of the businesses currently open on 101. Mayor Tony Kranz has pointed out that as more of the neighborhood was built out with impervious surfaces, the old stormwater system fell further behind, to the point where the city was pumping untreated runoff over the bluff and onto Beacon's Beach during storms. The 60-inch, 66-inch and 36-inch storm drain pipe now installed between Jupiter Street and La Costa Avenue is a direct response to that history, not a cosmetic upgrade.

Why the Overlap Is the Actual Story

Neither project alone changes much about how Leucadia sounds or moves. Together, they set up a specific and fairly narrow window. The Streetscape's underground drainage work, the loudest and most disruptive phase, is largely finished. What remains is surface work, curbs, sidewalks and driveways, which is why you're seeing lane grinding at night rather than pipe trenching during the day. That phase is supposed to close out by fall, ahead of the December loan deadline. The quiet zone gates, meanwhile, are the rail project's most design-ready piece, which means they're plausibly the first thing built once funding clears the federal-to-local handoff.

That creates a rough sequence: sidewalk and lane disruption tapering off this fall, followed by a stretch where the loudest daily irritant on this stretch of 101, train horns at E Street, D Street and Leucadia Boulevard, has a real funded path to going quiet, even if the timeline for actual construction on the gates isn't public yet. The two new at-grade crossings and the Verdi undercrossing will take longer, since design work on the former is still well short of complete.

None of this means the corridor goes silent by New Year's. It means the two forces that have shaped daily friction on 101 for the better part of six years, ripped-up sidewalks and horn noise, are on tracks that both point toward relief rather than more of the same, on a timeline the city has now put real numbers behind.

Life on the corridor hasn't paused for any of this. Encinitas 101 MainStreet Association has kept its Courtyard Rhythms concert series going on Friday evenings at 937 South Coast Highway 101 through September, and the city's Weds@Noon series is still drawing a lunchtime crowd to the Encinitas Library. The construction and the community calendar are running in parallel, which is probably the most honest way to describe how a project this long actually feels from the sidewalk.

What to Actually Watch For

• Night paving work between Grandview and Jupiter is active this week. Check the Leucadia Streetscape Hotline at 760-512-3800 before planning an evening walk or bike ride through that stretch.
• The city's next informational update to council on the drainage project is worth tracking if you want a firm completion date rather than a seasonal estimate.
• Quiet zone design work at E Street, D Street and Leucadia Boulevard was tracking toward 90 percent completion by the end of this past summer. A construction timeline for the gates hasn't been published yet.
• The Verdi Avenue undercrossing has design and Planning Commission approval already in hand. Of the four rail pieces in the grant, it's the closest to shovel-ready.

You can follow the city's own project pages for the Streetscape and drainage work and read the full breakdown of the rail grant from The Coast News, which has covered both projects since their earliest hearings.
