Solar New York

Governor Cuomo has set the goal that in less than a decade and a half, 50% of New York State’s energy will come from renewable resources. To some, that goal seems to be a stretch, but the chatter I’m starting to hear indicates we might even do better. As Kaya Laterman wrote in the New York Times real estate section last week: Solar power in New York City may finally be having its moment. The number of residential projects across the five boroughs has risen to more than 5,300 this year from 186 in 2011, according to state officials, and there are another 1,900 in the pipeline. […]

A New Park Rises From an Old Garbage Dump: Parks as Critical Elements of Urban Infrastructure

Yesterday was a historic day for parks in New York City. While most tourists do not get to see much of Staten Island beyond the ferry terminal, a new urban park is taking shape in that borough on the site of the city’s last garbage dump (I mean “landfill”). Sunday, May 15th was “Discovery Day” at the Freshkills Park. According to the website of the New York City Department of Parks and Recreation, people were invited to: Discover Freshkills Park and explore 700 acres of the otherwise closed site with free tours and recreation. At 2,200 acres, Freshkills Park is almost three times the size of Central Park and the largest park to be developed in New York City in over 100 years. It also has a significant history as the site of the former Fresh Kills Landfill, which was the largest landfill in the world before closing in 2001. Since then, the landfill has been covered with layers of soil and infrastructure, and the site has become a place for wildlife, recreation, science, education, and art. As the park is built in phases, free tours and events provide early access for learning and exploration opportunities. On Discovery Day, eight miles of trails and paths will offer views of the park’s hills, creeks, and wildlife. A 5K course will be mapped out for runners and walkers. While this park will probably never have the glamor of the High Line Park in Manhattan, it will become increasingly important as Staten Island continues to develop and become more densely settled and more like New York City’s other outer boroughs. Like Prospect Park in Brooklyn, Van Cortlandt Park in the Bronx and Flushing Meadows Park in Queens, the Freshkills Park will be the site of large scale, borough and citywide events and day trips. The gradual opening of this park, and the importance of urban parks in general, is a quiet part of making our urbanized world a place more fit for human habitation. In fact, as the weather starts to warm up here in the northeast, people are emerging from their indoor spaces and spending more of their time enjoying the outdoors. In a world that is increasingly urban, we often overlook the importance of city parks as critical pieces of urban infrastructure. When hard-pressed city officials are balancing the demands of public safety, education, transportation, water, sanitation and homeless services with parks, it is easy to see why parks are often seen as a residual budget category. Nevertheless, day in and day out our urban parks are among the most important, utilized and even loved services of city governments. In PlaNYC 2030’s original 2007 urban sustainability plan, the Bloomberg administration set a goal that every city resident would live within a ten minute walk of a city park. This was a clear, operational and measurable indication of the importance of parks to urban life. There are a great many different types of urban parks and uses of parks. One use is for recreation- ball fields, tennis and basketball courts, pools, skating rinks, boating and sailing. Another use is ecological. Green space absorbs heat and carbon dioxide, assists in controlling storm water runoff, and can help preserve biodiversity. There is also the visual amenity offered by a park. In many cities, homes with a view of a park are more highly valued than identical homes without a park view. Parks can also provide a commerce-free zone for families. Most public spaces in America feature commercial venues of one sort or another: amusement parks, shopping malls, professional sports facilities, movie theatres and so on. This adds to the financial pressure on a family. Parks are often free of commerce or if there is a restaurant or ice cream vendor in the park, they do not dominate the environment. A family can bring their own food, sports equipment and games, and folks can relax knowing their wallets aren’t being emptied by the hour. Parks are also a place where friends and families can gather and where neighbors can informally and casually interact with neighbors. They are also a democratizing feature of urban life. There is no VIP line, charge, or special place for the elite in the typical public park. Rich and poor share the same space and facility. In this sense parks can contribute to social understanding and political stability. Park design can vary by topography, climate, culture, public demand and capital investment. Demand for new or redesigned park space will relate to the capacities provided by existing parks. Some parks are focused on active recreation, while others are simply quiet places to sit outside. Parks can include spaces for apartment dwellers to garden, run their dogs, or take a nap in the sun. Parks are an essential piece of urban infrastructure that enables high density living without diminishing quality of life. In rural areas people have a great deal of outdoor space that they own. Most of the time there are very few humans in those spaces but they provide an outlet for people to enjoy the natural world. There is little social engagement in these rural open spaces. Rural open spaces are critical resources as well, but they are different than urban parks. In cities most of us depend on public space to enjoy the outdoors. While most people in cities spend most of their time indoors, parks provide actual and implicit outdoor space. The fact is that if everyone indoors suddenly decided to go to their local park, they would be so crowded that it would serve no purpose. But people visit parks for relatively short periods of time and most people do not visit their local park on any given day. But the experience of the park provides a pleasant memory and the potential access may well be more important than actual park use. This means that a relatively small amount of land can meet the outside space needs of a relatively large amount of people. Skilled landscape design can enable a large number of people to use outdoor park space without being aware of the number of people present. Sound effects from waterfalls can mask the sounds of people. Trees, hills, ponds and other design features as well as public plazas surrounded by wooded areas without recreation facilities can be used to concentrate people but also leave natural areas less trafficked. In addition to publicly owned and operated parks, we see examples like New York’s Central Park which is owned by the City of New York, but operated by the nonprofit Central Park Conservancy under contract to the City. It is also possible for private developers to build and operate public spaces for public use or to build and operate private spaces for the use of their own customers or residents. In some cities a private developer may be given permission to build more densely than the rules allow, in return for the “community benefit” of open space or a public plaza or facility. In some cities, institutions such as museums, botanical gardens, universities and zoos maintain both restricted spaces and spaces that are typically open to the public for events. Columbia University has a stunning central plaza that is open to the public and is a popular stop for tour buses and tourists. These public-private partnerships can help extend the reach of public spaces. New York’s Freshkills Park may be a tough sell for those of us who remember the huge landfill that used to be there. But anyone born in the 21st century will not associate that space with garbage, and over the next half century it will become of increasing importance to the development of Staten Island and New York City. New York has a long history of park development with an eye toward the future. When Central Park was designed, the land surrounding it was not yet developed. Imagine Manhattan without Central Park. Imagine the Upper West Side of Manhattan without Riverside Park. Someday people will have a hard time imaging Staten Island without Freshkills Park. And parents will say to their children, “Can you believe that long ago there was a garbage dump underneath this park?” And the kids will ask, “What is a garbage dump?” — This feed and its contents are the property of The Huffington Post, and use is subject to our terms.

Saving California Parks – With New Ideas and Tech

SAN FRANCISCO – Standing on the corner of Mission and 16th Street, a mixed neighborhood of yuppies and Latino working class, Carlos Lopez, 19, said he’s heard of Mount Tamalpais State Park. But he thinks it’s far away and isn’t sure how to get there. When told it is only about 10 miles north of where he was standing, he was a little surprised. The images of rolling hills and rocky shores shown on an iPhone stoke his imagination. “Man, this is nice,” he said. “Now I want to go.” The fact that Lopez, who grew up in San Francisco, doesn’t know where Mt. Tam is has become a major concern for those who care about the future of California’s state parks. In recent years the parks have suffered some serious setbacks, from cuts in funding to charges of mismanagement of those funds. […]

Ready for My Close-Up!: Parks in the Movies

With the Academy Awards coming up Feb. 22, people around the world are thinking about their favorite movies, actors, directors and even sound tracks. For some of us in the world of city parks, we watch movies through a narrower lens: scenes shot in parks (“How about those Cossack-like park rangers on horses chasing down poor Santa in Central Park in Elf?”). And some of those movie scenes we all watch raise questions about how location shooting affects the parks and their use, and we wonder if the park will be a star, or an extra. In almost four decades working in and around New York City’s parks, I have seen their rebirth and improvements documented in movies, as the city’s parks they have gone from graffiti-strewn, menacing and dark backdrops to glamorous ambassadors for the city and its now record levels of tourism. As a teenager in the 1970s, I worked picking up garbage in parks on Manhattan’s Lower East Side; it was a low point in the city’s history, echoed in the movies of the era. From neo-realistic dark dramas like The Panic in Needle Park(1971) to the violent revenge fantasies of Death Wish (1974, with its climactic scene in Riverside Park) and the summit meeting of street gangs in Riverside Park of The Warriors (1979), Hollywood both chronicled and exaggerated the dangerous and seamy side of the city.

Park Equity and Park Reality in NYC

While most of the land in New York City sits beneath single family homes, like the one I grew up in on East 59th Street in Brooklyn, most of the people in New York live in apartments. I’ve lived in Manhattan apartments for a long time and I’ve been fortunate to live in the same apartment on Morningside Drive since 1990. Across the street from my home is the beautiful Olmstead-Vaux-designed Morningside Park. When I first moved into my apartment, gunshots were a too frequent sound from that park. Today, it is a wonderfully restored space with new playgrounds, picnic tables, gardens and ball fields. The drug dealers are long gone, replaced by families, picnickers, dogs and lots of kids. New York City’s revival can be seen in the restoration of the city’s parks. For New Yorkers, the parks are everyone’s backyard. […]
