Project Information

Construction specifications typically require contractors to seed slopes and provide means for the growing vegetation to stabilize the ground, through the use of blankets, mats, grids or similar devices. The challenge in Alaska and similar remote regions is that such solutions often work well only in the short term. After a year or two, the vegetation dies due to a combination of extreme climate and lack of periodic upkeep and is thus ineffective in preventing erosion. This long-term lack of sustainability leads to environmental damage to the slopes and any water bodies and other areas into which the silt-laden erosion flows.

The objectives of this project are two-fold. First, we intend to identify, and develop anew if so indicated, physical methods, products, and procedures that are practical and can be used to improve long-term erosion control of disturbed slopes resulting from construction operations in remote cold climates. Second, the project will develop suggested contractual means, including specification language, by which a public agency, such as a state department of transportation, can assure long-term upkeep of such slopes.
