The work is expected to begin this week and will cost the city $200,000. The mayor's office said the rest of the City Council was consulted before the decision was made, and no one expressed concerns.

Portland leaders have hired the National Police Foundation to investigate whether there is a bias in how the Portland Police Bureau handles political protesters.

In February, Mayor Ted Wheeler agreed to an independent investigation following reports about text messages between Joey Gibson, the leader of the group Patriot Prayer — a Vancouver-based far-right group that attracts white supremacists and has engaged in violence — and Lt. Jeff Niiya, who headed up the Police Bureau's Rapid Response Team.

Gibson has organized protests in Portland that brought white supremacists to the city. Some of those events turned violent as members of Patriot Prayer clashed with anti-fascist protesters.
