The Area Permit Parking Program (APPP) began in the Homestead area in 1987. A primary purpose of the APPP is to prevent commuters from parking in residential areas.
The Homestead area contains three parking zones within its boundaries:
Zone C is in the upper homestead area encompassing OHSU up to Fairmont;
Zone D is a small zone that encompasses 6th Avenue Drive down to Terwilliger Boulevard;
Zone E is below Terwilliger down to Barbur Boulevard.
