Economic valuation methodologies used by the Corps as identified from the policy and planning "Planning Guidance."


The most important part of the evaluation process for the Corps is basing their decision on NED, the national economic development. The federal objective that the Corps engages on when dealing in water resource planning is to primarily decide upon a plan that contributes the greatest amount of benefits to national economic development, "...consistent with protecting the Nation's environment, pursuant to national environmental statutes, applicable executive orders, and other federal planning requirements." The Corps and the Federal government define contributions to NED as increases in the net value of the national output of goods and services, expressed in monetary units. The contributions to END include increases in those goods and services that both may be marketed and those that may not be marketed, i.e. natural resources.
