A smaller section should simply be cut off for pedestrian-use only uses, 24/7. That way, there wouldn't be scary "no parking" signs, cars being towed away, uncertainty about the longevity of the district, etc.

Portland has plenty of great examples as precedents. Several portions of NW Kearny street in the Pearl are pedestrian-only; the alley by Voodoo Doughnuts, since being walled off, has become a vibrant eating plaza; and the streets around SW 3rd and Harrison are surrounded by pedestrian walkways, cutting off "streets" that would otherwise have been carved through.

The "entertainment zone" is a good idea, but it needs to be permanently adopted - even if that has to happen on a smaller scale.

I'm sure the OLCC is going out of its way to be accommodating to this plan and to businesses who now want to have outdoor seating where there was none before.
