Welcome to the Mobile Planning Community Toolbox

Planning plays a vital role in supporting the Corps of Engineers Civil Works water resources development mission. Through planning activities, including feasibility studies, Continuing Authorities Program studies, watershed studies, comprehensive/large scale studies, general reevaluation studies, validation studies and other post-authorization change studies - and more, Corps planners help decision-makers identify water resources problems, conceive solutions to them, and compare the importance of the inevitable conflicting values inherent in any solution.

The Planning Community Toolbox includes a wealth of information for planners and project delivery teams, including the policy, guidance, processes, and tools that are used every day in planning.
