The Democratic governor will be in the capital Thursday and Friday.
Spokesman Richard Carbo says it's the first of several trips Edwards will make to Washington in the next few weeks to discuss flood assistance with Obama administration officials and congressional leaders.
Edwards is asking for $2 billion in federal disaster block grant money from Congress.
The governor says Louisiana had at least $8.7 billion in damage from the catastrophic flooding. The figure is expected to rise.
Carbo says Edwards' focus this week will be to describe the extent of the damage to congressional leaders. He'll testify before a House subcommittee and meet with U.S. Housing and Urban Development Secretary Julian Castro.
