Clevelanders love to complain that the city’s lakefront is pathetic in comparison with Chicago’s. With miles of bike trails, marinas, beaches, cultural institutions and attractions such as Millennium Park and Navy Pier, Chicago’s shoreline is one of the world’s great urban wonders. But what counts most in the comparison is that the Chicago lakefront grew out of decades of focused civic willpower. Cleveland has no such record. To be sure, it’s had recent triumphs on the lake and the river, including the Rock and Roll Hall of Fame and Museum, the Jacobs Pavilion concert stage, the new Rivergate Park for recreational rowing and the upcoming Flats East Bank office project. Given this background, it’s big news that the Cleveland-Cuyahoga County Port Authority has come forward with a credible, well-conceived plan to rethink and rebuild critical pieces of infrastructure on the lakefront and along the river.
