The Philadelphia District maintains more than 550 miles of navigable waterways in the Delaware River Valley. We own and maintain the Chesapeake & Delaware Canal and the 5 high span bridges that cross it. The District nourishes beaches in New Jersey and Delaware to reduce the risk of storm damages to infrastructure. We operate 5 dams in eastern Pennsylvania that have prevented hundreds of millions of dollars in floods damages. We execute a number of smaller projects under the Continuing Authorities Program and Environmental Infrastructure authorities. And we provide technical assistance to other federal, state, and local agencies.
