The easiest way to get this achievement is to take over the Verona Warehouse (The one north from Corleone Compound) in Little Italy. Doing this immediately when starting the game may prove difficult. You may want to take over some businesses/rackets and maybe do a few missions before attempting this so you can get a feel for the game.
Theoretically, you could get this achievement by destroying an enemy compound, however, this would be far more trouble than its worth if you don't have Little Italy controlled already.
