Build the network on sequential /24's in the 192.168.x.x range. Makes
routing easier. Using 10.x.x.x addresses leads to people messing up
netmasks and broadcasting all over the network. I've done two city wide
networks this way and it looks good in theory but sucks in practical
applications. 

Then, as you need 'public' IP's you can route smaller subnets of public
addresses throughout this network. This also keeps your public servers
limited to  ones you know about.. (at least some).

DHCP? You have got to be kidding for a MAN. 

Networking philosophy opinions are like bellybuttons, we all have them, we
all like our own, other peoples look funny, and most of them smell bad.
