The future of Portland's West Hayden Island is set to be decided before the end of the year.
The Port of Portland has wanted to develop West Hayden Island for decades. The latest plan would split the land between port development and natural areas that the public could use.
A recent health impact analysis by Multnomah County found the development would degrade air quality. Port officials say the problems are overestimated.
The port is still in discussions over how to mitigate possible harm to the environment.
Mayoral candidates Charlie Hales and Jefferson Smith say the annexation is moving too quickly.
Current mayor, Sam Adams, says he hasn't taken a position on the plan. But he says the city council will be ready to vote on it in December.
Adams explained, "What council will be looking at are: what are the facts, what is the proposal, and what do we want to do? But a decision one way or another needs to be made."
Annexation will first go before the city’s planning and sustainability commission in the next few weeks.
