Sea Level Rise Awareness

Sea level rise affects everyone in the City of Arcata!  While significant effects may be seen 50 to 100 years from now, the City Council is considering now the policies they will put in place.  These policies directly affect:

  • Infrastructure - Roads, Electrical Stations, Wastewater Treatment, Water
  • Commercial and Industrial Properties
  • Residential Properties
  • Agricultural Land and Facilities
  • Recreation and Natural Habitat Areas

We encourage all citizens to become informed and to weigh in on the discussion.  Below you will find a draft of Sea Level Rise policies, and slideshow of maps that show what our tidelands looked like in 1870, a FEMA floodplain map, adaptation measures, and two maps showing the proposed protection zone.  Click on any of the maps for a PDF.
