Reminds me of this article I read recently:
Is Portland ready to start building streets for smaller trucks?

The Federal Highway Administration suggests having traditional 30-foot trucks in mind when designing residential and local city streets and intersections. But in its latest design guide, the National Association of City Transportation Officials recommended preparing for a 23-foot vehicle in such situations. The City of Chicago has followed suit; its latest street guide (with Nelson\Nygaard as lead consultant) also introduced a 23-foot delivery van for neighborhood streets.

It goes on about various sized delivery trucks, although I don't think they were related to grocery store deliveries, which normally require larger trucks due to the amount of stuff they get delivered. Still, there is room for improvement.
There are other buildings in downtown Portland where semi truck trailers backup into the loading zone and end up blocking traffic. It seems like a fairly common thing, actually.
