Abstract: Harbor Point in Baltimore, Maryland has undergone a transformation from industrial hub to environmental cleanup site to a commercial office space hub over the span of the last 40 years from 1985 to present day. This evolution has spanned a myriad of advancements in deep foundations, waterfront revetment, underground barrier technology, groundwater modeling and maintenance, and re-development. Site development included stabilization of the shoreline with an engineered embankment, dismantlement of the industrial plant, early use of MODFLOW to assess various environmental remedies, application of geosynthetics and hydraulic barriers to contain contaminants and control groundwater flow, and design and approval of driven piles through geosynthetics to meet environmental controls and support high-rise structures. Together, these evolutionary achievements in groundwater control and deep foundation design have maintained efficacy of the in-place environmental remedy and facilitated revitalization of the waterfront and development of an entirely new neighborhood for the city. With one parcel remaining for re-development, current plans contemplate the re-use of existing abandoned foundations to act as improved ground, developing piles to support cantilevered floors, and pile compatibility with aggressive groundwater chemistry.
