How does a tree bond work?

[SteamMIA]

We are in the process of building a home on a lot with three large oaks. We are doing everything we can to minimize the damage to the canopy and roots during construction but the city has required us to put up a tree bond on the oaks. How do these work? I understand that we need to get an estimate of replacement value but do we have to put up that whole amount in escrow somewhere? That sounds like a huge financial outlay (~$100k) for something that hopefully will never be used. I'm going to call a local place that issues tree bonds but I wanted to be somewhat knowledgeable about the process before I pick up the phone. Thanks.
