The move violates the city's own code. Are they going to fail to follow their own laws that they impose on the rest of us? The property is zoned EX. Whether R2D2 is called a rest area, a campground, or temporary housing, it is not a permitted or conditional use in an EX zone. To change the zoning and potentially get a conditional use permit requires public notice, letters sent to surrounding property owners, a statutorily required waiting period for public testimony and comments, and a public hearing. This can't legally be done in 30 days - and it should never be a forgone conclusion without first getting public feedback. Shame on Fritz for trying to exercise dictatorial powers and violate the city's development code. The end does not justify the means.
Looks like grounds for another lawsuit against the City, but by some other faction, which will probably just result in another out of court, settlement.
Why don't they just move to Portland State University and pitch their tents in the public park blocks, there? "The City is Your Campus". It's more than just a convenient place to take a shit, whenever you happen to find yourself downtown!
