There are four primary land allocationcategories applicable to Corps projects: (1) operations (i.e., flood control, hydropower, etc.), (2) recreation, (3)fish and wildlife, and (4) mitigation.Land use classifications All lands are acquired for authorized project purposes and allocated for these uses.The classification process is a further distribution of project lands by management categories, which basedupon resources available and public needs, will provide for full utilization while protecting project resources.(EP 1130-2-550 15 Nov 96 1-4.d.)Market Area The geographic range that people are expected to reasonably travel from to visit the Basin area.Master Plan A conceptual document guiding the Corps responsibilities pursuant to Federal laws andregulations to preserve, conserve, restore, maintain, and manage the project lands, waters, and associatedresources. The plan addresses all resources including but not limited to fish and wildlife, vegetation, cultural,esthetic, interpretive, recreation, mineral, commercial, and outgranted lands, easements and water.

Non-statutory mitigation actions may take the form of actions torestore project value, such as replacing trees, soil stabilization, and providing new, relocated, or replacementamenities.Acronyms and Glossary 7-3
