Geotechnical Aspects of Waterfront Parks: Case Historiesby James S. Dransfield, Rittenhouse-Zeman & Associates, Inc, Bellevue, WA,

Abstract: This paper presents several case histories of waterfront developments, and describes the general approach that the geotechnical consultant should take in the design of these projects. The case histories show how geotechnical engineering knowledge was able to improve and stabilize park sites while working with the onsite soils. This approach saved costly removal and replacement. All these projects required experienced inspectors who could work with the contractor to achieve the end result. Such projects include: Protection of waterfront fill soils with armor stone, riprap and filter rock layers; Construction of an embankment by filling above and lateral displacement of soft dredging spoils in a controlled mud wave; Floating trails in soft organic-rich soils by utilizing geotextile fabric and light weight wood structures; Construction of a timber crib seawall designed to stabilize actively eroding waterfront bluffs in permafrost terrain.
