Walk North Coast Highway 101 between Jupiter Street and La Costa Avenue this month and you will pass concrete barriers, staging equipment, and a stretch where crews tunneled beneath the La Costa Avenue intersection just to keep pipe installation moving without closing the road outright. Curbside parking on the west side has been restricted on and off for months. Buyers touring listings a block off the highway have learned to time their visits around lane shifts.
What those buyers usually don't expect is what the sale data actually shows along that same corridor: no discount for any of it. If you're comparing Leucadia against Cardiff-by-the-Sea, Old Encinitas, or a quieter stretch of Carlsbad, the six years of dust and detours on Coast Highway 101 are worth understanding, but not for the reason most buyers assume.
The active work is called Segment C West and the North Coast Highway 101 Drainage Improvements. It runs from Jupiter Street to La Costa Avenue, broke ground in March 2024, and the city's own project page currently targets completion in late summer or fall of 2026. Crews have finished installing 60-inch, 66-inch, and 36-inch storm drain pipe along that stretch and are now finishing cleanout boxes, with work near Moorgate Road, while the water main gets extended toward La Costa Avenue.
This isn't cosmetic paving. Leucadia has a documented flooding problem that predates the streetscape project by decades, one severe enough that the city has, at times, pumped untreated stormwater over the bluff onto Beacon's Beach during heavy storms. That history is part of why Mayor Tony Kranz has been blunt about the stakes.
"There's been historic flooding in Leucadia that has been exacerbated by growth."
The drainage work has to go in before the roadway and mobility upgrades, which is why residents are living through pipe trenches before they get to see new sidewalks, bike lanes, or the roundabout planned for Grandview Street.
The idea for this corridor overhaul dates to 2008. The first construction contract wasn't awarded until 2020. Since then, the project has moved in pieces, and where your target property sits relative to those pieces matters more than most buyers realize.
| Segment | Span | Status as of August 2026 | Funding |
|---|---|---|---|
| Segment A | Marcheta St to Basil St | Complete, summer 2022 | Fully funded and built |
| Safety & Mobility interim project | Basil St to La Costa Ave | Complete, fall 2022 | Fully funded and built |
| Segment C West + Hwy 101 Drainage | Jupiter St to La Costa Ave | Under construction since March 2024, targeting late summer/fall 2026 | $20M California iBank loan (must be spent by December 2026) plus a $4M HUD grant, against an estimated $32M cost |
| Segment B (ultimate improvements) | Basil St to Jupiter St | Design complete, construction not scheduled | $25M, entirely unfunded |
| Segment A South + drainage | A St to Marcheta St | Not started | $10M, entirely unfunded |
Two of the five pieces have no construction date and no funding source. That's not a footnote. If your prospective home sits between Basil Street and Jupiter Street, or between A Street and Marcheta Street, the "streetscape is almost done" story a listing agent might tell you applies to a different stretch of the highway than the one you're buying on. The segment currently underway is on a real clock, because the state loan behind it has a December 2026 spending deadline. The other two segments have no comparable pressure forcing them forward, and both were still described as unfunded in the city's most recent public updates.
Even the funded segment hasn't moved in a straight line. The completion estimate has already slipped from a flat "summer 2026" to "late summer or fall 2026," and the city amended its construction management contract with Psomas in March 2026 and its engineering agreement with Michael Baker International in April 2026 to cover the extra time. Six years in, "nearly finished" has needed to be qualified more than once on this corridor.
Here's where the obvious assumption breaks down. A buyer looking at a home near an active trench line, with a construction hotline number posted on utility poles, tends to expect a price break for the inconvenience. Encinitas data doesn't show one.
Redfin's read on the market over the three months ending in May 2026 put the citywide median sale price at $2.2 million, up 8.1 percent from the same period a year earlier, with homes averaging 19 days on market and multiple offers typical. A separate read using February 2026 figures put the median closer to $1.8 million, down modestly year over year, with days on market stretching toward 61. Those two snapshots disagree on direction, which says something on its own: even locally-focused analysts can't agree on whether Encinitas cooled or heated up this year, and neither dataset attributes any of that movement to the Leucadia corridor specifically.
What both sources agree on is the sub-market pattern. Coastal pockets, Leucadia included, continue to command premiums tied to surf access and ocean proximity, while detached condos and townhomes in New Encinitas, away from the beach and away from the construction zone, trade in the $800,000 to $1.2 million range. If eighteen years of intermittent trenching were suppressing value, you'd expect that gap to have narrowed. It hasn't shown up in the pricing.
The likely explanation isn't complicated once you frame it correctly. Buyers on this corridor aren't pricing the orange cones in front of the house today. They're pricing the finished corridor: flood relief that ends a decades-old drainage problem, new sidewalks and bike lanes, a restored tree canopy, and a roundabout at Grandview Street that's already been rendered and approved. The disruption is temporary and priced accordingly. The infrastructure is permanent and gets capitalized into the number on day one, well before the paving crews leave.
If you're comparing a Leucadia listing against something in Cardiff or Carlsbad, the useful diligence question isn't whether construction will eventually wrap. It's which segment your address falls into and whether that segment has a funding source with a deadline attached to it.
A property between Jupiter Street and La Costa Avenue is inside a segment with a hard December 2026 spending deadline behind it, which means the disruption has a real end date even if it slips by a season. A property between Basil Street and Jupiter Street, or between A Street and Marcheta Street, sits inside a segment with no funding at all as of this writing, which means there's no honest answer to "when" beyond "whenever the city secures another loan or grant."
Before writing an offer on this corridor, it's worth asking your agent to walk through a short list:
None of that changes what the home is worth today. It does change what kind of neighbor you'll have on your street for the next one to three years, and whether that neighbor is a paving crew finishing a funded job or an empty design file waiting on a grant.
Does living near active construction actually lower what I'd pay in Leucadia? Not based on the sub-market data available. Coastal pockets along this corridor, including Leucadia, continue to trade at a premium over inland and non-coastal Encinitas segments, and neither major pricing snapshot from 2026 shows construction proximity depressing values.
When will the Leucadia Streetscape actually be done? The currently funded segment, Jupiter Street to La Costa Avenue, is targeting late summer or fall 2026 completion per the city's project page. Two other segments, covering Basil Street to Jupiter Street and A Street to Marcheta Street, have no funding and no construction start date.
Why does the drainage work have to happen before the sidewalks and bike lanes? The storm drain and water main installation has to go in first because the roadway paving and mobility improvements sit on top of that infrastructure. The city has stated the sequence explicitly in its own project updates.
Is there a way to track construction status before I make an offer? The city maintains a Leucadia Streetscape hotline and a dedicated project dashboard with segment-by-segment updates. Checking that against the specific block you're considering takes ten minutes and tells you more than a general "the highway is under construction" caveat ever will.
Corridor projects like this one reward buyers who ask block-specific questions instead of neighborhood-wide ones.
