About the hub
The Oregon Design Criteria Hub is an interactive mapping tool that provides site-specific climatic and geographic design criteria for construction projects governed by the Oregon Residential Specialty Code (ORSC) and the Oregon Structural Specialty Code (OSSC).
For the
ORSC, all of the following criteria is shown:
- Ground snow load
- Basic design wind speed
- Seismic Design Category
- Weathering potential
- Frost line depth
- Decay potential
- Air freezing index
The hub also indicates if the entered location is within the jurisdiction of a municipality that has adopted the ORSC Section R327 Wildfire Hazard Mitigation Standards.

For the
OSSC, all of the following criteria is shown:
- Ground snow load
- Basic design wind speed
- Seismic ground motion values
- Frost line depth
The tool was developed by Oregon State University’s (OSU) Oregon Explorer Program, which is a collaboration among OSU Libraries and Press (OSULP) and the Institute for Natural Resources (INR) at OSU.
