I have to say that this is one of the stupidest things I have ever seen. This author does not take into account emergency situations including emergency vehicle access. How are fire trucks and personnel suppose to maneuver in a narrow 15 foot wide space. Also if I am not mistaken, San Francisco is in an area that has potential for earthquakes. Those 15 foot alleys will be death traps for people should an earthquake cause a building collapse. Furthermore fire can jump building to building and 15 feet is not a lot of separation. You solve one problem and create many others. Not realistic at all. Jay

While those are all things to take in to account, they're not insurmountable problems. Japan and Italy both have similar streets and suffer earthquakes. Many cities worldwide have similar streets and all have to deal with emergency services access. And this ignores that in many apartment complexes there are areas between buildings that do not have adjacent vehicle access. Just because our large American emergency and delivery vehicles aren't compatible doesn't mean the whole idea is bunk.

I want to highlight the total space we’re setting aside for cars in the current setup. When we multiply the width of the lanes (38′ 9″) by the length of the block (425′), the result is more than 15,000 square feet of space for cars, just on a single block of McAllister Street.
The space set aside for cars may be excessive, but don't forget about all the single-family housing
that consumes most of the land in SF. When people think of San Francisco they think of tall buildings
and skyscrapers, but don't realize that about three-quarters of the city looks like this:

San Francisco Sunset District

Remember that San Francisco is suffering through an affordability crisis caused in large part by a massive housing deficit. We need space for a lot more units than we have, and no one wants to build up...
...because they were too busy building outward?

There are probably a number of streets in San Francisco already 15 feet wide. These:

Town law here is there must be 12 feet of room left after street parking for street parking to be legal to allow emergency vehicles to pass through. So 15 feet should be sufficient. And as mentioned afterward, narrow streets are common in earthquake prone areas of other developed countries. Though in both Japan and Italy, I'd guess fire trucks are narrower to deal with narrower streets. A Tokyo street:

Yes, that's building to building, just like the original McAllister proposal that started the thread.

That's also a 20 foot wide right of way, 5 feet wider than the original proposal.
