This is an alley and not usable for delivery or thru-traffic. The alley speed limit is 10mph, is intended for homeowners to access their garages. All deliveries should be done to front of homes on Memorial Dr or Arboretum Ave.
The alley has stop signs at each of three intersections - so it is much slower/inefficient for drivers. 
The alley also has children playing, riding bikes, playing ball, running from house to housem, etc.
