  1. 0:20A digital map introduces six main risk areas between San Luis Obispo and Humboldt Bay.
  2. 1:03Moss Landing, Highway 1 and Santa Cruz face flooding and beach-erosion risks.
  3. 1:34Elevated-water scenarios show exposure around SFO, US 101 and South Bay marshes near Alviso.
  4. 1:57The assessment identifies vulnerable areas around Oakland International Airport and West Oakland.
  5. 2:38The area east of the Petaluma River faces a highlighted risk of levees overtopping.
  6. 3:26The walkthrough reaches Humboldt Bay before directing viewers to the interactive map and full report.

KPIX | CBS NEWS BAY AREA takes a wider view of California's flooding problem: not just where water reaches the road, but which roads, airports and levees could become points of failure.

Using a three-dimensional map, the station's meteorologist walks through a study of infrastructure vulnerable to flooding and high tides. The report drew roughly 100,000 views in its first day, far beyond the station's usual audience for a regular upload.

The most pointed warning concerns a small area immediately east of the Petaluma River, where the report highlights a high chance of river levees overtopping. Nearby Lakeville Highway appears on the map. Elsewhere in the North Bay, the assessment flags Highway 37, the San Rafael Canal area and US 101 through Corte Madera.

The airport sections make the potential disruption especially tangible. The map shows exposure around San Francisco International Airport, Oakland International Airport and the South Bay marshes near Alviso under different elevated-water scenarios. These are mapped risks, not footage of those places already underwater.

As we reported here, KPIX has also followed workers building a wooden flood wall in Mill Valley. This report broadens that local picture, tracing coastal erosion and flooding concerns through Pismo Beach, Moss Landing and Santa Cruz before finishing at Humboldt Bay. The presenter also points viewers toward an interactive map so they can explore the locations themselves.
