This document summarizes and compares the international planning approaches of Seattle, WA and Porto Alegre, Brazil. For Seattle, it outlines the goals of protecting the environment, connecting people and places, maintaining a strong economy, and including socially and economically affected groups in decision making. For Porto Alegre, the goals include democratic management with public participation, improving life quality, integrating public and private actions, and protecting the environment. Both cities aim to involve the public, though Porto Alegre provides less accessible language and Seattle takes a more marketing approach. The key lesson is the importance of environmental sustainability and public participation in planning.
