Project Description & Details

An ambitious and highly acclaimed urban reclamation project created in three phases over a period of eight years, the award-winning High Line is noted for its innovative design and sustainability. Located in New York City’s Meatpacking District and Chelsea neighborhood of Manhattan, the length of the High Line traverses 23 uninterrupted city blocks, 30 feet in the air, with expansive views of New York City and the Hudson River. At a total of 1.45 miles the High Line is considered the “longest greenroof” in the world to date.

The former abandoned elevated railway was championed by the non-profit group “Friends of the High Line” and designed by the landscape architecture firm of James Corner Field Operations and architects Diller Scofidio + Renfro with planting design from Piet Oudolf and engineering design by Buro Happold. ZinCo USA provided the technical basis for all the green roof design concepts in terms of plants, walkways, and leisure areas with Floradrain® drainage elements and ZinCoblend M growing medium.

One of the most expensive parks ever constructed, the High Line is also one of Manhattan’s most popular destinations and receives 5 million visitors per year. From an overgrown abandoned railroad trestle to a delightful changing panorama of self-seeded landscape and re-introduced indigenous vegetation, original and restored rails, and contemporary artwork to a wide variety of places for relaxation and enjoyment, the iconic High Line is dearly loved as a remarkable landscaped city park in the air.

Project Description & Details

The Hotchkiss School is an independent boarding school; founded in 1891, it provides an education of unsurpassed quality to 598 students in grades 9 through 12, and to a small number of postgraduates. Installed in July, 2012, the green roof on the School’s newest Biomass Treatment Center is an exciting addition to an already beautiful campus. LEED Gold certified, currently it is one of only three such power plants in the country. Designed by Centerbrook Architects, the facility is part of Hotchkiss’ commitment to becoming a carbon-neutral campus by 2020.

Merging into the landscape, the Biomass Treatment Facility has a low profile and an undulating, sloped green roof. Installed by Apex Green Roofs, the sedum carpet green roof system was provided by ZinCo USA on top of a Sika Sarnafil waterproofing membrane. The Floradrain FD25-E drainage element – the proverbial “heart” of the green roof system – lies on top of the protection mat, hugging the waves of the roof, ensuring proper drainage while retaining a specific amount of water for the roof’s vegetation.

The Hotchkiss School Biomass Treatment Facility is featured in the month of September in the 2013 Greenroofs & Walls of the World™ Calendar.
