Liberty Island, a 186-acre habitat restoration project in Yolo County, California, featured the development of a mosaic of tidal aquatic habitats beneficial to Delta native fish species such as Delta smelt, longfin smelt and salmon.
  • With limited access to the island, heavy construction equipment was barged to the project one piece at a time.
  • Construction included creating open water channels, tidal emergent marsh, seasonally inundated floodplain habitats and removing levees which impeded tidal and flood flow.
  • State of the art GPS-enabled equipment was used to ensure proper grading elevation down to the inch.
  • In all over 190,000 cubic yards of material was moved to complete the project.
  • The project is critically important to the continued survival of listed fish species like salmon, longfin smelt and Delta smelt.
  • Liberty Island is protected with a permanent conservation easement and a non-wasting long-term endowment to manage the property in perpetuity.
