Design Overlay Zone Assessment Project

  • The DOZA Final Report was published in April 2017.

  • Portland’s (d) overlay gets a closer look with the Design Overlay Zone Assessment project.

  • The Design Overlay zone is applied within areas of the city with special scenic, architectural or cultural value as well as areas of rapid growth near transit stations.

  • The project will evaluate what’s working and what’s not in the Design Overlay zone.

  • Project Timeline Implementation of recommendations will begin in 2017.

The Bureau of Planning and Sustainability (BPS), in collaboration with the Bureau of Development Services (BDS), initiated a consultant-led assessment of Portland’s Design Overlay zone. The project, called Design Overlay Zone Assessment (DOZA), documented and assessed how the tools that carry out the (d) overlay affect the outcomes for discretionary and nondiscretionary reviews. The final deliverable is a set of recommendations for practically and effectively improving the system.
