You don't need someone local to figure this out. 
Step 1: Look at all of the available imagery for clues, no driveway is visible but there are vehicles on the north side of the building in one of them
Step 2: Check the USGS 3D elevation data (or LIDAR if it's available, to see if there is a sign of a road in the landscape, it turns out that there is a road like structure visible here north of the building that connects to Stump Lane
Step 3: turn on the Bing Streetside overlay, click where the road like structure intersects Stump Lane to see if there's a driveway there. Turns out that there's a driveway visible on streetside. Problem solved and it only took a minute or so.
