Abstract: Construction of the Presque Isle Shoreline Erosion Control Project in Lake Erie at Erie, PA began October 1989 and consists of fifty-eight offshore segmented breakwaters with beachfill. The breakwaters are 45.7 meters (150 feet) long each with a crest elevation of 2.4m (8.0 ft) above Low Water Datum (LWD = 173.31m (568.6 ft) International Great Lakes Datum) and are separated by a gap of 106.7m (350 ft). Construction is scheduled to be completed no later than November 1992. Littoral processes, construction sequence and initial shoreline response due to the completed breakwaters with a comparison to existing empirical methods are presented.
