Federal Emergency Management Agency/Provisionally Accredited Levee website

Provisionally Accredited Levee (PAL) websites support FEMA's implementation of the Guidelines for Identifying Provisionally Accredited Levees. They provide a collaborative environment where federal, state and local governments and private citizens may organize and share information related to the PAL process.

The PAL websites are built using the same open source wiki software that powers the Internet's popular Wikipedia encyclopedia and the Department of Defense's Intelipedia systems. The wiki software, plus suitable extensions and custom configuration, provides an editable website for PAL community members to record and track PAL status across the region.
