On Tuesday JPMorgan Chase & Co. announced that it will rebrand Washington Mutual's California branches with the Chase name on March 30.

The change is expected to cost $300 million as 708 bank branches are renamed. A further $75 million will be spent on opening 20 more Chase branches in California this year.

The efforts will be extensive, given the deferred maintenance at many of WaMu's urban locations and the lack of vaults and teller windows at several of WaMu's newly designed branches.
