Storm Surge Raster datum

The user manual calls for the storm surge raster to be in NAVD88. However, I already have my DEM in MTL, so I am not using a datum correction for the DEM elevation. I assume that the surge should be in the same datum as the DEM, but the manual gives me pause since it calls for NAVD. I just wanted to make sure there isn't some additional behind-the-scenes datum conversion going on for the surge (beyond what you might input in the VDATUM file or MTL-NAVD conversion factor)
