PERHAPS no open space project in recent memory has been as hyped as New York City’s brand new High Line Park. Phase One of the project opened in June to a unanimous response of Ooo’s and Ahh’s from an eagerly awaiting public. Haven’t heard of it? Here’s what you need to know: It’s a park…perched atop a hulking, thirty-foot high, eighty-year old, decommissioned railroad. And everybody loves it.

In the mid-eighties, a group of neighborhood residents, enamored by the High Line’s post-industrial beauty and second-act potential, formed the Friends of the High Line public advocacy group, countered efforts from local business owners intent on demolishing the rusting structure, and sponsored an international design competition, from which came the proposal for High Line Park. Now one-third realized, High Line Park is a one-two punch of wabi sabi urban design so potent every big city wants one of their own.

So what is it that’s drawing droves of New Yorkers and foreign tourists alike? How could it be that when I visited one sunny Saturday, I actually had to wait in line to be ushered in? There must be something special below the High Line’s thin surface profile of engineered soils and crafted concrete pavers.

LONG before the High Line Park design proposal inspired the collective efforts of Chelsea locals, the money-granting pens of New York City officials, and the imaginative designs of an impressive roster of starchitects, there was the flâneur. In the mid-nineteenth century, civic planner Baron Haussmann was commissioned to modernize Paris. His idea: bisect the city’s dingy, medieval street network with wide boulevards, and displace one third of all Parisians in doing so. More than creating additional breathing room or speeding the city’s traffic, Haussmann’s interconnected, linear boulevards reshaped Paris’s public culture. For the first time, the city’s amenities and spectacles could be engaged in orderly, predictable fashion. The sidewalk became a stage for a new urban archetype, what poet and critic Charles Baudelaire coined “the flâneur.” Beneath the shade of newly planted street trees, and in the light of modern, gas-powered street lamps, these members of an elite, developing bourgeois class embraced a newfound sense of leisure and walked the city in order to experience it. What was once a gritty, working-class environment became for the flâneur something of an outdoor shopping mall, an environment to be consumed, if only through the senses.

Sound familiar? The upscale shopping district of Fifth Avenue, tourist-overrun St. Mark’s Place, and Williamsburg’s Bedford Avenue all are relatives to Haussman’s boulevard model. These urban spaces go beyond their original intent as functioning streets to become hybrid environments for shopping, dining, socializing, and voyeurism. By some just-right recipe of commercial, residential, and transit conditions they became generators of a culture of leisure and delight.

High Line Park is a novel upgrade of this sort. More than a chic strolling promenade, it is a captivating, one-of-a-kind amalgamation incorporating some of the most articulated culture New York City has to offer. Along their stroll, High Line Park flâneurs take in the sights of Chelsea’s fashionable restaurants, contemporary galleries, and high-end boutique stores. Using the sidewalk to engage Chelsea’s street culture is so last year. Being elevated above the action, visitors are one more step removed from the city, effectively squaring the flâneur experience. Not just neighborhood amenities but now street culture itself is an object to be admired. In this way, High Line Park is an urban theme ride, a slow speed tram made from a masterfully fashioned landscape which quietly weaves its way through museum neighborhoods.

CHELSEA has as rich and diverse a history as any neighborhood in New York. From High Line Park’s thirty-foot vantage, this history is uniquely on display. In fact, many of the park’s most rewarding views incorporate the neighborhood’s structures of yesteryear. To learn from its local history and make our High Line Park experience all the richer, I’d like to introduce my friend and field guide, Alan Kleinberg.

Alan is a true New Yorker, born and raised. He was a prolific photographer on the scene during New York’s legendary art boom. As we began our walk of the southernmost section of High Line Park’s Phase One, he recreated for me the old Chelsea he remembers. For him, it was a low-key neighborhood prized by adventurous creatives for its quiet streets, ethnic storefronts, and low rents. (Low rents. Seriously, believe it.). It was something of a playground. Just southeast, the city’s art galleries were being priced out of Soho because of rising rents, and word spread that the overlooked neighborhood north of Greenwich Village was fast becoming a new destination for cutting-edge artists. One by one, New York’s galleries fatefully packed their bags for westbound settlement. What greeted them was a canvas of urban proportions blank for culture-making. Through the charged creative energies of artistic visionaries, what was once a looming manufacturing corridor was transformed into an international visual arts hot spot.

Then, but increasingly less so, Chelsea’s architectural palette was primarily a mix of warehouses and production facilities. These warm brick facades reflect the bustling conditions of an old-world, developing urban economy. Today, they appear against the Hudson River as nostalgic stars setting the stage for some of High Line Park’s most rewarding views. We can thank generations past for bequeathing us this robust city fabric that develops richer character with age.

Seasoned New Yorkers like Alan recognize the city’s dynamic culture feeds off contrast. This is what gives the city its notorious grit. Bankers and musicians; students and homeless; cabbies and bicyclists, all sharing the same streets. Contrast is strongly at play in High Line Park, but it’s more than the city versus nature dialectic evoked in Central Park. It’s also deeper than the informed, culturally critical eye of the flâneur against the working city. Alan reminds me that the creative energy that once characterized the neighborhood has been replaced by an atmosphere of consumption. In the High Line structure, risk and curiosity has been replaced with safety and predictability. What once lured graffiti artists as a hidden gem has now had its subversiveness uprooted to allow for paths wide enough to fit passing strollers. I imagine it may feel somewhat similar to having your favorite under-the-radar, local café reviewed by Rachel Ray. The taming of the High Line signals the end of Chelsea’s golden era.
