Navigation

The District maintains 500 miles of navigation channels across the region. The McFarland, a deep-draft hopper dredge owned and operated by USACE Philadelphia District, serves in a Ready Reserve status, operating on the Delaware River and responds to urgent dredging missions along the East and Gulf coasts.

Dredging and Beneficial Use

When dredged material is clean, USACE looks for opportunities to use the sediment beneficially. Examples include restoring degraded marsh and creating islands, which can provide critical habitat for wildlife and enhance coastal resiliency.
