According to NYC Parks 5 Borough Citywide Operations and Technical Services Sustainable Facilities Division:
In the spring of 2007, the Five Borough Technical Services Division of the New York City Department of Parks and Recreation installed its first green roof system atop their headquarters, the Five Borough Complex on Randall‟s Island. Since then, the Technical Services division, in cooperation with the Parks‟ GreenApple Corps, has expanded the green roof program to encompass over 30 unique growing systems covering 30,000 square feet of our roof. As the fifth largest green roof in New York City, the 5-Borough project is not only a key component of the Parks‟ commitment to reducing its carbon footprint, but it also serves as a way to educate and inspire park staff and patrons, as well as supply a resource for peers in the field.
The 5-Borough green roof distinguishes itself from others, as it is the only known green roof in the country to feature distinct systems side by side. These systems vary by type of growing medium, depth of growing medium, and plant selection. By using a variety of planting systems and monitoring their progress, we are identifying the types of green roof systems that will thrive in the NYC urban environment.

A green roof is a thin layer of vegetation installed on a traditional flat or pitched roof. Although the specifics of green roof design may vary, all green roofs have the same basic components (Fig. 1 from the bottom up): waterproofing layer(s), a root barrier (to prevent the plantings‟ roots from growing through the roof), water retention/water drainage layer, growing medium, and plants.

There are two types of green roofs: intensive and extensive. Intensive green roofs are greater than 6" deep and allow for a greater variety of plants including shrubs and even trees to be considered. They are similar to traditional rooftop gardens and often provide social and recreational uses. Intensive roofs can require more maintenance than extensive roofs and may also be more costly to install. By contrast, extensive green roofs are much shallower; their growing media are typically less than 6". They are lighter weight systems that provide primarily ecological and economic benefits. Plants likely to flourish on extensive green roofs are more specific and include sedums, succulents, alpine type plants, and some grasses. Extensive green roofs contain fewer layers than those of intensive roofs and tend to require less maintenance....

Roosevelt Island PS/IS 217 teacher Ursula Fokine, PS/IS 217 PTA's Olga Shchuchinov and Erin Olavesen, and iDig2Learn's Christina Delfico joined Borough President Brewer and her staff on the August 12 tour of the NYC Parks Department Randall's Island Green Roof.

Ms Fokine said the purpose of the tour was:
... to be inspired by the work being done by the Parks Department. We are looking to design our roof, that we have now received such generous funding for, and we are looking to make our roof a combination of a space for our students and also to be environmentally exciting and sustainable.

We came today to see see the kind of plants and planting systems that are available and choices we have to now make to get our roof off the ground....

Manhattan Borough President Brewer added:
...I've never seen a roof like the school on Roosevelt Island in terms of size...

... Today is inspiring. What we learned is that we can do different things on the roof...  this roof is so large it could be a learning laboratory, you could have all the cultural/artistic but you can also have the real green roof stuff....
