My best guess is that you would want to use directional boring in that case. A 
small hole every couple hundred meters, horizontal bore and duct pullback 
between holes. No personal experience here other than watching it being done 
for new pulls into existing developments. No need for digging up 
yards/sidewalks/parking lots, just a bunch of potholes at the new junction 
box locations and a single horizontal bore down the property line from the 
street, intercepting each of the potholes.
