Facility Permits/Public Improvements

What are facility permits?

Facility permits are needed when subdivisions, partitions and other development projects are conditioned to build public improvements on County roads. Improvements include sidewalks, curbs, gutters, streetlights, paving, traffic signals and more.

The permits are not issued until plans are approved by our Engineering Plan Review team. The process includes:

  • A Public Improvement Contract (surety bond or cash surety) and final construction inspections to assure improvements are built to County standards
  • A one-year (minimum) maintenance period 
  • Final maintenance inspections
  • Release of contract and closure of permit

Apply for a facility permit

  1. Submit a completed Design Option Form, wet signed and stamped original, and a Facility Permit Information Form (mailed or delivered in office). 
  2. Pay the administrative deposit paid by credit card (call 503-846-3843 or in person) or check (by mail or in person). The amount is listed in the County Land Use Notice of Decision or the City Comment Letter (projects within a city.) 

Public Permitting and Services PortalThe facility permit record will then be available in the Public Permitting and Services Portal, and our Electronic Plan Review/ProjectDox system will notify the engineer to upload plans.
