Replacing Grape Vines With Fruit and Nut Trees?

We are going to be moving to the country next month. The property has a vineyard and one corner the vines were damaged by a fire. The whole thing is watered by drip irrigation. I really don't plan to just have a vineyard and would like a farm with all types of nut and fruit trees.

Could I just clear out where the dead/burned vine was and plant something new in it's place? I figured it would also get watered when the vines do. The ground is sandy so I know I would have to add something to the ground before we plant but I don't know what. We live in the California's central valley.

Our zone is 9 I believe.
