big city

i making something for my friend this is what he wants me to do (regular city but I do need a fenced off military zone. small but big enough for a few jeeps, tanks and two buildings <one is a small base for solders, the other s supply depo> the fenced zone will have no gate. I also need a small air base, no runway but a helicopter pad 4x the normal size with 4 step stairs up to it.the two military bases must be at opposite sides of the city. lastly near the water. hill land around it) and this is the starting building


update
