Please describe the project specifications

The purpose of this project was to protect the 600ft of shoreline right in front of the historic Eastpoint Lighthouse. Built in 1849 and originally known as the Maurice River Lighthouse, the two-story brick structure now known as the East Point Lighthouse is the second oldest lighthouse in the state of New Jersey. Over the last decade, the historic building has become vulnerable to storms and flooding due to years of shoreline erosion and today sits just 90 feet from mean high water. The design used to protect the Eastpoint lighthouse consists of eight sections and each section has three elements: The Geotube® unit, the scour apron, and the Sand Filled Mattress (SFM) on top of the scour apron. The SFM is made by a durable composite and was used in this project to provide extra weight to the scour apron.

What is unique or complex about the project?

Due to the historical importance of the building and the great success on protecting it makes this project very unique and rewarding. Many other options were used in the past and none of them provided the proper erosion protection that the Geotube® technology provided.
