Step 2 - Concept Development

Before you begin to invest significant engineering and technical resources into the design of your project, the City requires that you meet with public works staff to review and refine your development concept based on your development goals, the conditions of your development site, and the required public works and infrastructure improvements to serve your development.

During this step in the permitting process, the City requires detailed information about your development site, planned land uses, topography, soils, adjacent public rights-of-way, encroachments, intended connections to City water and sewer infrastructure, and detailed calculations for preliminary stormwater and sanitary sewer designs. 

NOTE: If your project is on an Oregon Department of Transportation (ODOT) state route within the City limits of Portland (click here for map), your project may be subject to additional review and approval through ODOT’s engineering group prior to the issuance of City’s Public Works Permit. ODOT’s review can run concurrently with City review phases.  ODOT’s review needs may add a significant time to your project schedule.  Please ask City of Portland Transportation staff if you have questions about state routes within city limits.

Concept Development Meeting and Fee - After the initial Concept Development submittal is accepted for review, a concept review fee (based upon permit type) is invoiced. Payment of the invoice must be made prior to the Concept Development meeting--scheduled approximately 2 weeks after the submittal is accepted and processed by city staff. Your project team meets with city review staff at the concept meeting to discuss the development, review redline comments, and identify next steps in the public works project and plan development.  When corrections are requested, an 'interim review' submittal is required.

Once Concept Development plans are approved, Public Works will provide a fee invoice for the next phase of review, Design Development. Invoiced fees must be paid prior to submitting Design plans. If there is a related building permit, site development permit, or land use final plat checksheet with approval conditions tied to the public improvements under review, Public Works also will provide guidance for satisfying those conditions, including: an applicant signed Public Works Permit, payment of invoiced fees, and City approved performance guarantee (i.e. performance bond, letter of credit, cash in lieu of a bond, etc.).
