Event tent water run off, sandbags sold out everywhere because of imminent hurricane fall. Any ideas to control run off coming into the tent?

I was able to add on walls through the event company I'm now just worried about water flowing under the walls.

The size is 75x30 Entrance way/walls stand are about 7 feet Pretty standard white tent style The ground is asphalt

Not directly in the path of it just going to get some serious rain. But I've got an event and the tent is already rented tomorrow.
