The last thing many residents in Napa County want is another devastating tsunami. That’s why they’re hoping for a positive resolution with an upcoming natural hazard mapping board meeting, scheduled for 9:30 a.m. today.

This includes the ability to adjust coastal defenses, coastal safety and tsunami safety awareness. We are currently in process of implementing many of these recommendations.”
