Long Range Planning Projects

Samoa Wastewater Planning Project

This project is funded through a planning grant from the State Water Resources Control Board and is intended to evaluate a consolidated wastewater system to serve the Samoa Peninsula.  Humboldt County selected a engineering team comprised of GHD and SHN to lead this project.  The following project documents have been completed:
