What's a permit, easement and property worth?

I am the owner of the property and the new sign permit.The sign is not in the air. Permit is for a 14x48 back to back monopole.Traffic count 22,000 per day. Competition close to me charges $800 per side.Commercial land is worth 100,000 per acre in this area. If i sold the property the sign would sit on and a easement plus the permit how much would it be typically worth??? How much land is needed for sign???

Monopole needs 9SQF of the land.

So what would be the value of the permit and easement???
