Erosion Control

At the Iowa Department of Transportation, the preservation of limited natural resources is one element considered when planning construction projects. When Iowa DOT is constructing or moving a road, it often needs to move earth. As good stewards of the land, precautions are taken to assure that the disturbed ground does not erode, or the sediment wash away only to end up in another area.

While the $3 million, 2-mile-long beautification project now underway along Interstate 515, also known as U.S. Highway 95, near Henderson, Nev., may seem small in comparison to what the Nevada Department of Transportation typically undertakes – look no further than price tag for the completion in Late August for the "first phase" of Interstate 11 – the I-515 project illustrates a key aspect of the agency's highway construction philosophy, said Tony Illia, a public information officer with the Nevada DOT.

As sea levels rise in Hawaii, the beaches—and roads—are taking a hit. In 2016, the waters on Oahu's Windward Coast ripped off two big pieces of the Kamehameha Highway. Crews performed repairs, and while Hawaii's transportation officials said the repairs would help to deter future erosion, they said the fix wasn't permanent, the Honolulu Civil Beat reported.

The Army Corps of Engineers is moving forward with plans to begin construction on an erosion mitigation project in southcentral Alaska that's been in the works for nearly 20 years. The city of Kenai has been working with the Army Corps since 1999 on plans to halt erosion and prevent the loss of valuable residential and commercial property atop the bluff along the Kenai River, The Peninsula Clarion reported (http://bit.ly/2ldO6F1).

A large road project is progressing as planned in southern New Castle County, Delaware. The new U.S. 301 will reportedly improve safety, manage truck traffic and reduce congestion; support approved and proposed economic development in a key Delaware growth area; enhance the region's ability to compete for economic development; create needed jobs; improve local access to the Northeast Corridor Rail (Amtrak), commuter rail (SEPTA) and bus (DART) services; improve livability in the region; and reduce fuel consumption and greenhouse gas emissions.

Case Construction Equipment, the National Wildlife Refuge Association, the U.S. Fish & Wildlife Service and Team Rubicon teamed up for an equipment operator training and erosion abatement project at the Laguna Atascosa National Wildlife Refuge in Los Fresnos, Texas.

CORNISH, N.H. (AP) The New Hampshire Department of Transportation hopes to start work next year on a project to eliminate erosion around supports of a historic covered bridge connecting the state to Vermont. The Eagle Times reports state officials met with the Cornish Selectboard and residents during a public hearing on the $2 million project.

ATLANTIC CITY, N.J. (AP) Erosion from Hurricane Sandy will delay the rebuilding of the Atlantic City Boardwalk along Absecon Inlet and likely increase the original $10 million project cost estimate, officials said Jan. 25. After Sandy’s floodwaters receded, officials said the storm actually saved money because it swept away a portion of the dilapidated section of boardwalk along the inlet that had been inaccessible for years and already was slated for demolition.

Finn Corporation’s TRU-Mulch line consists of six mulches specially designed to meet the demands of various erosion control and hydroseeding projects. The wood fibers used throughout the line originate from virgin poplar and pine wood chips from forests of the eastern United States.

For Southern California counties the periodic, yet unpredictable, arrival of the El Niño climate pattern equates to winter and spring rainfall totals that are significantly higher than historical averages for that region. This year’s rainfall — coupled with numerous post-fire erosion areas — is capable of causing mudslides and debris flows that can wash out sections of roadway and clog and break underground drainage pipes.

Hunter Industries was the general contractor for the recently completed I-35 improvements to the Texas Department of Transportation (TXDOT) on-system interstate reconstruction through New Braunfels, Texas. Noteworthy to the project were the environmental controls, particularly with respect to storm drainage and water quality.
