Master Plans and Impact Mitigation Plans

Master Plans and Impact Mitigation PlansA conditional use master plan is a plan for the future development of a use that is subject to the conditional use regulations. An approved master plan is intended to ensure that you will be allowed to develop in a manner consistent with the approved plan.

 

The master plan must include proposed uses and possible future uses that might be proposed for at least 3 years and up to 10 years. An approved master plan remains in effect until development allowed by the plan has been completed or the plan is amended or superseded.

 

Master plans may be completed at varying levels of detail. Generally, the more specific the plan, the less review that will be required as the future uses and developments are built.

 

Impact Mitigation Plans: Impact Mitigation Plans are an alternative review to the conditional use master plan process for large institutional uses, often in the IR zone. The regulations are addressed in Chapter 33.848 of the Zoning Code.

 

Central City Master Plans: Central City Master Plans are intended to add development potential and flexibility for projects in specified areas of the Central City plan district. The regulations are addressed in a section within the plan district chapter (33.510.255).

 

Gateway Master Plans: Gateway Master Plans are intended to add development potential and flexibility for projects in specified areas of the Gateway Plan District. The regulations are addressed in a section within the plan district chapter (33.526.330), as well as within the chapter specific to the review (33.833).

 

Portland International Raceway (PIR) Master Plans: PIR Master Plans are required for most development within the Portland International Raceway Plan District. The regulations are addressed in Chapter 33.566 of the zoning code. 

 

Master Plan Procedures

 

All conditional use master plans are processed through a Type III procedure. Amendments to an existing master plan may be processed either through a Type II or Type III procedure.
