Last week, the three leading mayoral candidates came to WW's office for a joint endorsement interview. Although the three—State Rep. Jefferson Smith (D-Portland), former City Commissioner Charlie Hales and businesswoman Eileen Brady—agree on many issues, one that provides some useful contrast is the proposed $62 million Oregon Sustainability Center.

That project, a joint venture between the City of Portland and the Oregon University System, is meant to be a "living building" that generates all its own electricity, collects all the water it uses and processes its waste-water on site. A top priority for current mayor Sam Adams, the Sustainability Center fell afoul of skeptical legislators who rejected the university system's request that the state issue $37 million in bonds to pay for a big chunk of the project.
