The first phase of the long-awaited $25 million Portland Harbor dredging project — construction of a 9-acre confined aquatic disposal pit, or CAD cell — was completed early this month, wrapping up after 40 days despite bad winter weather, said Bill Needelman, Portland’s waterfront director.“It went exactly as planned,” Needelman said. “Now we can move on to the kind of routine dredging that should be normal for an urban harbor like ours.” The CAD was dug in a shallow, little-used South Portland cove.
