  • Portland’s d-overlay gets an update with the Design Overlay Zone Amendments package.

  • The DOZA proposal creates a new purpose statement, updates the thresholds that trigger land use reviews, and creates new design standards and design guidelines.

  • The project also makes some administrative changes that impact design review and the Design Commission.

  • The Design Overlay zone will encourage development that builds on context, contributes to the public realm, and encourages quality and long-term resilience.

Portland has received national and international acclaim for supporting a high-quality built environment through planning and urban design. In part, this is due to its long-standing tradition of design review, which occurs within the design overlay zone (or d-overlay). 

By 2035, the City is expected to grow by 123,000 households. Most of this growth will occur within the Central City and Portland’s neighborhood centers and corridors. The d-overlay aims to support the city’s evolution within these urbanizing areas.

Together, the Bureau of Planning and Sustainability (BPS) and Bureau of Development Services (BDS) are working on a Design Overlay Zone Amendments (DOZA) package of proposals to update and improve both the process and the tools used in design review. 

For information on ongoing process improvements, visit BDS’ DOZA project page.
