China Camp Road Flooding

car driving through deep water on road at China Camp
Data sets, photos, and design brief to kick-off an investigation of the effects of a road traversing through a tidal salt marsh.

The Situation

  • North San Pedro Road cuts through important tidal salt marshes of China Camp State Park in several places.
  • The scientists and land managers who protect the marshes are concerned that the road is disturbing the function of the marsh as habitat for rare and endangered plants and animals, and limiting the marsh’s natural ability to respond to increased rates of sea level rise.
  • The road already floods each year during extreme high tides, but the flooding isn’t predictable using tide tables because the weather makes a big difference in the actual water level.
  • The communities who live on either side of the State Park are concerned that the flooding may block their use of the road during an emergency. They are also concerned that more frequent flooding associated with sea level rise will cause the road to be closed.
  • Scientists, local politicians, and users of the Park are coming together to find mutually beneficial solutions.

Driving Questions

  • Is the road affecting the marsh?
  • What evidence do you see of the effect?

Investigative Questions

  • Are there differences in plant community on either side of the road?
  • Are there differences in animal communities on either side of the road?
  • Are there difference is water quality (salinity, temperature) on either side of the road?
  • Are there differences in water level on either side of the road?
