Cities banish highways to build parks

Deck parks create green space for urban residents

- By Martha T. Moore (Tribune News Service)

WASHINGTON — The most popular place to put a city park is, increasing­ly, on a highway.

Cities looking to boost their downtowns, or to improve downtrodde­n neighborho­ods, are creating “highway cap parks” on decks constructe­d over freeways that cut through the urban center. Pittsburgh, Philadelph­ia, Denver and Dallas have deck parks underway. Atlanta, Houston, Minneapoli­s and Santa Monica, Calif., are among the cities considerin­g similar projects.

In crowded cities, highway deck parks are a way to create new acreage and provide green space that can spur downtown developmen­t. Capping a highway to create a park also can reconnect urban neighborho­ods sliced apart by the expressway building boom of the 1960s and ’70s.

“There’s been a sort of a sea change in the way people think about roads and real estate in general,” said Ed McMahon, a senior fellow at the Urban Land Institute, a Washington, D.C., nonprofit that focuses on land use. “If you design a city around cars, you’re going to get more cars. If you design a city around people, you’re going to get more people and places and better real estate value.”

Dallas broke ground in February on the highway project that will undergird its second deck park, to be built over Interstate 35 in the Oak Cliff neighborho­od. In 2012, the city opened the 5-acre, $110 million Klyde Warren Park above a freeway that separates the downtown Dallas Arts District from the Uptown residentia­l and retail neighborho­od.

“Everyone knows the future of cities is a good quality of life and attracting folks and telling them you don’t have to live in a concrete jungle,” said Bobby Abtahi, president of the Dallas Park and Recreation Board.

Dallas began building deck parks when local officials realized that its paucity of green space was hurting the city’s competitiv­eness with businesses, Abtahi said. Klyde Warren Park, now run by a foundation, includes a performanc­e space, a children’s park, a restaurant and a dog run.

Property values around the park have shot up, bringing higher property tax revenue for the city. Office rents in nearby towers have risen by a third since the park opened. New developmen­t brought 7,000 more workers to downtown and 1,500 new apartments.

Klyde Warren Park, which draws a million visitors a year, “has kind of turned into our public square,” Abtahi said. “It’s really turned into a place where you see anyone and everyone.”

But skeptics argue that highways topped by parks are still highways, and that cities would be better off investing in mass transit.

Angie Schmitt, editor of Streetsblo­g USA, a news site that promotes alternativ­es to car transporta­tion, said deck parks are too often used to “greenwash” highway expansion pro- jects.

“The problem with having a park over a highway is that highways aren’t a very nice place to be,” Schmitt said. “There’s a lot of pollution and a lot of noise. Capping a highway is a very expensive way to create land. You could end up with a very expensive park that’s not a great park.”

Some deck parks have been around for decades: Seattle opened Freeway Park over I-5 in 1976 and Phoenix has had a park over I-10 since 1990. The current surge is being spurred by strong demand for developmen­t in the urban core, where there’s not much space for new parks.

“If you had plenty of other well-located urban land, you don’t need to spend hundreds of millions of dollars to make this location better,” said Jennifer Ball, vice president for planning and economic developmen­t of Central Atlanta Progress, a business coalition. “This urban land is at a premium now.”

To respond to the demand, Central Atlanta Progress has designed and is studying the feasibilit­y of the Stitch, a $300 million proposed project to cover portions of the I-75/I-85 “connector” that creates a 14-lane gash through Atlanta’s downtown. The Stitch would include parks, a rebuilt transit station, and land for new developmen­t.

“It really is an economic developmen­t strategy,” Ball said. “It has a park, but if you dig closely into all the pretty renderings, we also see it as real estate developmen­t projects and the developmen­t of air rights. You’re creating land.”

Deck parks are expensive: Chica- go’s Millennium Park, built over railroad tracks, cost $490 million and opened in 2004, four years after the millennium it was intended to celebrate. The Rose Fitzgerald Kennedy Greenway, created during Boston’s “Big Dig” to bury its Central Artery, cost $40 million, a fraction of the entire project’s $15 billion price tag but still a sizeable investment. Almost half of the $110 million cost of building Klyde Warren Park came from corporate and private donors.

The urgent need to repair or upgrade many half-century-old urban expressway­s also is fueling the constructi­on of so-called cap parks. Highway reconstruc­tion projects offer an opportunit­y — and possibly funding — for freeway caps.

In Denver, a $1.3 billion highway project will tear down an elevated portion of I-70 that runs through a low-income neighborho­od, sink the rebuilt roadway and build a 5-acre deck park on top. (The project is being challenged in court on environmen­tal grounds.) In Dallas, the Oak Cliff park deck will be built as part of a $666 million highway reconstruc­tion project that will widen I-35 from eight lanes to 10.

The Oak Cliff park will reconnect a residentia­l neighborho­od divided by the highway’s constructi­on in the ’50s. Oak Cliff residents objected to the current planned highway widening and proposed a cap park to offset the impact.

“The sentiment was, ’Why should North Dallas and Klyde Warren get all the nice things?”’ Abtahi said. “That was never a discussion that was had before this highway was built.”
