The 20-minute neighborhoods

Definition:
"20-minute neighborhoods are places where residents have easy, convenient access to many of the places and services they use daily including grocery stores, restaurants, schools and parks, without relying heavily on a car. They are characterized by a vibrant mix of commercial and residential uses all within an easy walk. They have higher concentrations of people and are complete with the sidewalks, bike lanes and bus routes that support a variety of transportation options."

Or comparing a neighbourhood using the three D's method:

• "Distance: how far can you walk in 20 minutes?
• Destinations: is everything you need on a daily basis within that distance?
• Density: are there enough people in the area to support the businesses and facilities you need for daily needs?"

"No one has to give up their car, or walk, bike, or take the bus to anywhere they want to go. Instead, they're aimed at making life easier for those who do want to walk, bike, or use transit -- by strengthening those modes."



"Important, too, the 20-minute neighborhood concept is aimed at meeting the broader strategic goals of Portland being a "high performance city."
