Each link you setup between 2 nodes in the mesh needs a /30. You can get 64 /30's in a /24. These will be depleted faster then you think, especially in a mesh configuration where you build links as you go depending on what you can see with decent quality values, which is not always as logical as it might seem on a map. Sometimes a building or a mountain is in between 2 nodes only 5km apart, while you can see nodes 20km away, and ofcourse you want it all to be redundant.

However, we have exactly 0 active users in NJ and so this is all moot for now. I gotta start somewhere.
I've seen nor been told anything that says AMPR must use mesh routing. Please, do tell?
And why would a ham microwave network need 16K addresses? are they offering service to the general public? As it happens I have plenty of space left over for just such a scenario - but more by luck than judgement :)

It's a work in progress but the following link should provide a link to the IP 44/8 address allocation document for NJ. http://mrprosser.g7ltt.com
We have very little AX.25 traffic in NJ but we do have a growing Mesh community which would benefit from this space.
Hands up if you want some!

I'm not sure I understand how breaking up subnets to counties like this is helpful. Is your routing actually hub-and-spoke like you say in the document, with a central router in each county? Do hams in that county connect directly to the central router for routing? Whether BGP, OSPF, or IPIP, I thought the plan for AMPR was do use mesh routing.
I've seen a case in AMPR where addresses were pre-allocated geographically instead of by network. Despite only having 3 registered hosts in the state, the coordinator did not have enough "free" space to allocate a large /19 subnet to a multi-county microwave network.
