Assessing the Cost of Coastal Land Creation Using Dredged Material

This report looks at the number of factors that influence the cost of building coastal land using dredged material and recommends cost-saving measures. For Louisiana’s 2012 Coastal Master Plan, marsh creation made up the largest budget percentage of all Master Plan projects at more than $22 billion of which about 85 percent was in construction costs. Recommendations for cost improvements include minimizing the distance sediment needs to be transported which includes adjustments to borrow sites and working on innovations to make the process of conveying sediment more efficient.
