(Amended by Ordinance No. 175158, effective January 15, 2001.)  It is the policy of the City of Portland to eliminate discrimination based on race, religion, color, sex, marital status, familial status, national origin, age, mental or physical disability, sexual orientation, gender identity or source of income.  Such discrimination poses a threat to the health, safety and general welfare of the citizens of Portland and menaces the institutions and foundation of our community.
