It seems to me that the use of alleys could be expanded in certain circumstances. For example, in higher density areas where there are wider and accessible alley ways, uses could be expanded to include markets, mobility paths and depending upon site specifics, storefronts and restaurants could be opened up and an entire pedestrian walkway could be developed - great connectivity to the rest of the urban form. Reminincent of the 'canyon' like pedestrian streets of Europe.
Don't know - just a thought.
