Portland's Urban Growth Boundary

Portland's Urban Growth Boundary (UGB) is a designated line that separates urban areas from rural land to manage city expansion. Established in the 1970s, its purpose is to contain development within the boundary, preserving farmland and natural spaces outside of it. By controlling sprawl, the UGB encourages more sustainable growth, efficient public services, and a focus on building dense, walkable neighborhoods. This approach aims to balance housing needs with environmental protection, fostering a livable city while maintaining its surrounding landscapes.
