Oak Harbor City Council adopted the architectural concept favored by the most citizens for the new sewage treatment plant Tuesday.

The adopted proposal, Concept B, was described by citizens as indicative of both modern and Northwest architecture, according to a city report.

City Engineer Joe Stowell explained that the concept was developed over the last few months after the city’s architect incorporated the ideas from a “charrette” group of local citizens and stakeholders. He said many citizens felt the original idea, Concept A, “didn’t hit the mark” and that more input was needed.

As a result, the city staff made a big push to gather feedback from the community, resulting in Concept B being the favored option.

Nevertheless, a small group of residents expressed concerns about the aesthetics of the concept Tuesday night. They spoke at the meeting about the importance of getting it right because of the long-term effect it will have on the look of the city.

“I really encourage you all to just reject both of them,” resident Hal Hovey said.

Several council members pointed out that the proposal was only a concept — at 60 percent — and that the design will be refined in the months to come. The failure to move forward with a concept would delay the project and cost the city hundreds of thousands of dollars, they said.

The council unanimously adopted Concept B.
