Civil Engineering in Oregon: what governs your project
Construction stormwater in Oregon is covered by the Department of Environmental Quality's NPDES 1200-C general permit for sites disturbing one acre or more. The Oregon Department of Transportation (ODOT) requires approach permits for access to state highways. Erosion control is a major focus during the long wet season west of the Cascades. Floodplain regulation is significant along the Willamette River and coastal estuaries.
Permitting & plan check
Portland's Bureau of Development Services runs a well-established electronic plan review process; other large cities like Eugene, Salem, and Bend operate their own portals. Many smaller cities and counties rely on third-party review agencies. Land-use approvals often run on a separate track from building permits in Oregon jurisdictions.
Good to know
- Western Oregon is in Seismic Design Category D due to the Cascadia subduction zone.
