Starting young finding section corners!
It's very fun watching him find the references to get started!

When your "surveyor in training" asks for his own sledge hammer.....maybe when you are taller than the handle bud!

Why a property or boundary survey?
-If you are installing a fence.
-If you are having a building addition or improvement (pool, shed, deck, etc.)
- If you are not sure where your property lines are.
These are just a few examples of uses for boundary surveys.
