Clark begins the article by examining the case of Broad Branch, a stream in Washington Creek, buried over a century ago in the name of malaria abatement. As problems, like pollution dumping into the Chesapeake Bay, have emerged as a result, " many cities have been undoing the past century's drainage projects, uncovering or 'daylighting' buried streams."

The article includes a guided tour provided by Keith Underwood, an Annapolis-based landscape architect hired by Washington D.C. to restore the Rock Creek drainage (of which Board Branch is a tributary). Underwood describes his work as "regenerative design," or a process of mimicking natural systems in a blend of art and engineering.
