Reducing Potential New Development in Areas with Natural Hazards and Drainage Constraints

Proposed changes to Portland’s Comprehensive Plan Map are designed to scale back development potential in certain areas of Southwest and East Portland. These places are generally hilly, with steep slopes, drainage problems and higher risks of natural hazards like landslides, wildfires flooding and/or earthquake damage. Steep narrow roads can make emergency vehicle response and evacuation more difficult during emergencies. And the amount of new development allowed under the current zoning, would strain limited infrastructure and increase risks to public safety and property. The proposed Comprehensive Plan Map changes are meant to help keep existing risks and problems from getting much worse over time.

Watch this video to learn more about changes in the Comprehensive Plan to address these problems, and check out the Map App’s “Risks and Service Gaps” layer to see where the proposed changes will occur. You can also use the Map App to submit testimony on the proposed changes to the Planning and Sustainability Commission as they consider the draft 2035 plan.
