Inside Cleveland's plan to become an 18-hour city

• The site is part of Cleveland's $3.5 billion vision for the future. The project would connect the Cuyahoga Riverfront to downtown's core with new residential units, office space, retail and entertainment venues.

Why it matters: Eighteen-hour cities — a designation created by the Urban Land Institute and PricewaterhouseCoopers (PwC) in 2015 — are considered the most attractive midsize markets for real estate investment and population growth because of their amenities, job growth and development opportunities that come at a lower cost than cities such as New York or Chicago.

• The most recent list of 18-hour cities includes Portland, Charlotte, Denver, Minneapolis, Salt Lake City, San Diego and Fort Lauderdale, all ranking among the nation's fastest-growing economies.

State of play: PwC considers Cleveland a "backbone" market with slower growth than 18-hour cities but with the potential to develop due to moderate housing and business costs.

• Other "backbone" cities include Detroit, Louisville, Indianapolis and Cincinnati.

What they're saying: City Council president Blaine Griffin sees Cleveland making strides with things like the Bedrock project and legalized sports betting.

• "Cleveland has the casino, sports teams, nightlife and museums," Griffin tells Axios. "The next step is providing access to the lake and riverfront, which would make the city more walkable and bikeable, and more desirable."

The bottom line: Cleveland's population growth numbers lag those of markets like Charlotte and Denver. However, that could change if the city's ambitious projects prove successful.
