3. Build a 15-foot-high electrified fence
Hopefully the zombies that pop up after the uprising will be the slow and shuffling kind, not the fast and jumpy ones. A 15-foot-high electrified fence should just about do the trick for the slower undead, but you still might want to add a few spikes to be safe. You might have some issues with your zoning board getting a 15-foot-high electrified fence installed. As with any home improvement project, just check with your local building inspector's office on that one and don't be afraid to make compromises.
