The Service announces the availability of engineering evaluation and cost analysis (EE/CA) reports and Administrative Records for Paradise Marsh (Operable Unit 1), Gunpowder Point (Operable Unit 2), and the F&G Street Marsh (Operable Unit 3) on Sweetwater Marsh. The public comment period ended on January 31, 2018. There is no estimated start date yet for the project construction, and a potentially responsible party has not yet been identified. All the appropriate documents for the project are here on our website, and can also be viewed in person at the Refuge Complex headquarters.
