The Northwest Maritime Center in collaboration with Pacific Northwest National Laboratory funded by NOAA Restoration Center completed design and construction of an experimental low-impact dock and associated eelgrass planting, along the Port Townsend waterfront (Port Townsend Ecosystem).


  • Design raised the dock higher, used concrete pilings, pushed the float into deeper water, narrowed walkways, used grating where possible, and tested reflective material on the underside.
  • Rubble in the eelgrass planting attracted algae which competed with eelgrass.
  • Initial monitoring was completed on eelgrass survival and light levels.
  • Final monitoring was never funded to evaluate the durability of benefits
