Case History of the Point Roberts Marinaby Jeffrey A. Layton, Layton & Sell, Inc, Redmond, United States,
Abstract: This paper presents a fifteen year history of the design performance of the Point Roberts Marina. The 1,000 berth small craft harbor is located on the Strait of Georgia, immediately north of the Puget Sound Basin. The marina was constructed utilizing several innovative design concepts: (1) narrow entrance channel coupled with curvilinear basin geometry to promote hydraulic circulation; (2) an annual sediment bypass operation to control downdrift shoreline erosion; and (3) the use of various coastal structures to protect the marina entrance channel from severe offshore wave activity. The performance of these design features, as well as other operational characteristics of the marina, are discussed in the paper.
