Summary

The plan analyzes restoration project design alternatives for two projects that are components of larger marsh restoration strategies, and were approved for engineering and design in a previous restoration plan. We have selected and approved a design alternative for construction of each, with a combined construction cost of approximately $214,932,290. The primary goal of the Spanish Pass increment in this plan is to create and nourish approximately 132 acres of historical ridge and 1,683 acres of marsh. This plan approves an estimated cost of approximately $100.3 million. This increment will create an estimated 2,816 acres of restored marsh habitat at an estimated cost of approximately $114.7 million.
