MOSS LANDING HEIGHTS, Monterey County — October 29, 2026. The transportation route connecting north Monterey County communities, the Moss Landing area and the rest of the Monterey Bay coast is the focus of a long-term resilience study. Residents of Moss Landing Heights and surrounding communities are being invited to help identify potential flooding trouble spots and transportation needs along the Highway 1–Elkhorn Slough corridor.
The Transportation Agency for Monterey County (TAMC), working with The Nature Conservancy and the Elkhorn Slough National Estuarine Research Reserve, is conducting a Planning and Environmental Linkages study. This is an early planning process, not a construction approval or a declaration that Highway 1 will be moved. It will assess possible responses to sea-level rise, tidal flooding and the vulnerability of an important coastal route.
What the proposed study means for Moss Landing Heights
For households in the broader Moss Landing area, Highway 1 is more than a tourist road. It links homes, employment, services and surrounding communities. A disruption at the Elkhorn Slough crossing can affect the practical choices people have for travel around the coast. The study therefore asks not only how the highway might be protected, but also how alternatives could affect safety, walking, biking, traffic and the neighboring wetlands.
TAMC’s official project information identifies several priorities: reducing tidal flooding, protecting habitat, maintaining road reliability, improving mobility for drivers and other travelers, and identifying potential projects that could compete for future state or federal funding. At this stage the agency is evaluating possible alternatives rather than announcing one selected design or a construction schedule.
How residents can participate
The official Highway 1 Elkhorn Slough Corridor public participation page offers a short survey in English or Spanish and an interactive project-area map where residents can share observations. The agency also offers a sign-up for project updates.
Useful comments can describe routinely flooded or congested locations, pedestrian and bicycle conflicts, trips affected by closures, access to businesses and services, and the needs of people who rely on the roadway. Comments should distinguish personal experience from confirmed engineering findings.
Earlier community outreach information circulated by local transportation advocates listed a December 3, 2026 open house from 5 to 7 p.m., but its venue was still marked to be determined. Anyone planning to attend should verify the time, location and final scheduling on the agency’s current project page before traveling.
Why the Elkhorn wetlands matter
The agency says the estuary faces both ecological damage and physical exposure to higher tides. It is studying ways of addressing the transportation corridor and coastal environment together. Those are related objectives, but a possible engineering solution that helps one part of the corridor may have costs or tradeoffs elsewhere. That is a reason to participate while alternatives are being developed rather than assume that a route has already been chosen.
