Yes, but only on your side of it. A survey protects against accidental encroachment.
What if my neighbor built on my side?
This is a civil trespass matter. The city does not enforce private boundary disputes.
Can utilities remove my fence?
Yes, if it crosses an easement. They are not required to replace or compensate.
Herndon FAQ

Not recommended. Install inside your line to avoid encroachment disputes and difficult maintenance access.
