City officials appeared to favor the “Portland Loo” public bathroom design for a permanent facility in Lewiston. City of Portland, Ore. LEWISTON — The city could install a permanent public restroom in a downtown location later this year if funding is approved by the Lewiston City Council. During a workshop this week, a majority of the council appeared in favor of an option to pursue a permanent public bathroom structure, known as the “Portland Loo,” or a similar style, which have become popular with municipalities. As of now, $131,000 toward the project is included in next year’s Capital Improvement Plan, which is on course to be approved by the council later this month.
