(Portland, OR) -- Portland Mayor Ted Wheeler is proposing a ban on camping in most parts of the city between 8 a.m. and 8 p.m. Wheeler says they've invested millions of dollars in shelters, Safe Rest Villages and new temporary City-sanctioned camp sites. The ordinance would also ban garbage, gas heaters, and parts operations for bikes and vehicles. It would be enforced with two warnings and then potential criminal penalties. Public comment will be taken next week. If it's approved, the ordinance would take effect July 1st.
