1996 Portland Maintenance Plans
• Oregon land use laws encourage compact growth, discourage sprawl
• Maintenance Plan Transportation Control Measures include land use measures
• Portland Metro-area 2040 Growth Management Plan encourages more density and planned growth in “centers”
• Metro-area funding priorities support transit, bicycle and pedestrian improvements
2004 Portland Maintenance Plans
• Metro recently revised transportation control measures; these measures continue to support alternative transportation
• New “Contingent TCMs” in maintenance plan contingency plan are triggered by growth in vehicle miles traveled per capita– 5% increase in VMT/capita triggers further
study; – 10% increase in VMT/capita triggers further
transportation control measures
2040 Plan: Principles
• Encourage efficient use of land
• Protect and restore the natural environment
• Provide a balanced transportation system
• Create vibrant places to work and live
• Encourage a strong local economy
2040 Plan: Transportation
• Street designs fit land use context
• Streets are retrofitted to include sidewalks and bikeways
• Street connectivity requirements allow easier walking and access to transit
• Frequent transit service provided on all major streets
How is it Working?
• Infill is occurring faster than expected, within UGB
• Transit ridership 1990-2001 outpaced population growth and daily VMT
• VMT/person stabilizing
• Mixed use development is occurring across the region
How is it Working? CMAQ/STP funding 1992-2005
How is it Working? Light Rail Transit System 1996-2007
How is it Working? Transit
• 29th largest metro area with 13th largest annual transit ridership
• Transit eliminates 58 million vehicle trips/year
• 72% of riders have the choice of using a car
• 30% of riders are commuters; 22% use transit for recreation
How is it Working? VMT
How is it Working? Air Quality (8-hr ozone)
