Island Building and Habitat Restoration: Utilizing Dredged Material for Environmental Benefits

Posted by Kimberly Walters on October 19, 2023

Island building and habitat restoration have significant environmental benefits, improving aquatic and land-based ecosystems. Working under LS Marine alongside Ramsey County, the U.S. Army Corps of Engineers, Saint Paul District, and the Minnesota Department of Natural Resources, Brennan built up islands at Pigs Eye Lake in Saint Paul, Minnesota.

The project's master plan features seven islands, sand beaches, marsh habitat, and land plantings. We utilized dredged material from the Mississippi River in an environmentally beneficial way to build the islands. Here's how it happened and why it works!

Restoring Habitat in the Great Lakes to Save Endangered Species

Posted by Nick Patterson, Regional Project Manager on November 19, 2020

The Interstate Island Avian Habitat Restoration Project is listed as one of the many Areas of Concern (AOC) projects within the Great Lakes. Interstate Island is a small parcel of land located within the Duluth-Superior Harbor along the St. Louis River Estuary. Due to rising water levels, the island has shrunk in size by half in recent years, and along with-it important wildlife habitat has disappeared. The need to restore the rare avian habitat on Interstate Island has been a priority for years, and it came to fruition in 2020.

Fighting Scour With Articulating Block Mats

Save Money with This Long-term Fix for Scour Problems

Scour poses a large threat to the stability of any structure that is partially or entirely underwater. It may develop slowly over time, or be brought on quickly by an intense rain event or seasonal flooding. In some cases, such as along a shoreline, scour can be very evident. In others, scour can go unnoticed for an extended period of time. Whether it is taking place around the footing of a bridge pier, along the base of a sheet pile wall, or along a tailrace on a dam, scour may not be evident until the structure begins to show signs above the water. At this point, the structure is beginning to fail and repairs must be done soon to avoid a total loss of integrity. Repairing scour and erosion issues that may be going unnoticed in any location is vital as it will save a lot of money in the long run, and extend the life of the structure.

The Significant Value of Replacing America's Railroad Bridges

Posted by Kimberly Walters on June 26, 2018

---Updated July 25, 2022, by Kimberly Walters---

Upgrading infrastructure in the United States of America has long been delayed and is now reaching a critical point. Replacing railroad bridges that are old or have exceeded their useful design life is just as important as any other element of our nation’s infrastructure. Bridges are a small component of an extensive railroad system. However, if taken out of service, a whole line could be shut down. Railroad companies would lose time, expenses would increase, and commodities would be delayed.
