Don't even need to cross state lines in this case - there's plenty of wilderness and low-density space in Washington (even Western Washington) where development is a fraction of the cost of building and operating a facility in Seattle. Build in a cheap area and shift the surplus into social services and vocational training to help people get off the treadmill.
Relocation should be behavior based (so not "vagrancy", which is a BS charge, but actual public misconduct or documented threat of self-harm). X strikes and you're relocated unless you can fund an appropriate bond.
The rest of the state is probably a healthier place to heal in any event... easier to control access to drugs and alcohol and limit the violence from street predators. The street isn't a very supportive environment....
