Arcata city officials say they want to use the wetlands for wastewater treatment for as long as possible
The treatment plant isn’t only at risk from rising sea levels … but also from rising groundwater and tectonic forces causing the land to sink, according to the 2018 assessment compiled by local sea level rise expert Alderon Laird. Laird has said to expect .9 feet of sea level rising by 2030, 1.9 feet by 2050 and 3.2 feet by 2070. … Arcata city officials are discussing moving the treatment … but that’s too expensive to do right now.
