Department of Environmental Protection and Lenox Hill Neighborhood House Announce Completion of 2,400 Square Foot Green Roof and Garden
Project was Completed with $40,000 Award from DEP’s Green Infrastructure Grant Program;
Green Roof and Garden Will Improve the Health of the East River and Help Clean the Air
New York City Department of Environmental Protection (DEP) Commissioner Carter Strickland today joined Lenox Hill Neighborhood House Chief Planning Officer Laura Lazarus to announce the completion of a 2,400 square foot green roof and garden funded, in part, by DEP’s Green Infrastructure Grant Program. The multi-purpose space located on the roof of the Lenox Hill Neighborhood House on East 70th Street in Manhattan will be used to provide hands on educational, recreational, and therapeutic programming for the non-profit’s clients. In addition, the specially designed gardens and landscaping will absorb and store more than 4,500 gallons of stormwater each time it rains, keeping it out of the combined sewer system and helping to make the East River and New York Harbor healthier. The new green roof will also help clean the air and reduce the building’s heating and cooling costs. The $110,000 project was funded with a $40,000 award from DEP’s Green Infrastructure Grant Program and $70,000 in matching funds provided by the Lenox Hill Neighborhood House.
“Projects like these do not only provide an enjoyable amenity for our Green Infrastructure Grant Program partners, they help improve the health of our waterways – which benefits all New Yorkers,” said Commissioner Strickland. “Rooftop gardens like the one here at Lenox Hill Neighborhood House combined with the thousands of bioswales and stormwater green streets we have started installing are a cost effective way to tackle one of our toughest environmental challenges and beautify our communities in the process.”
“Our new Green Roof and Garden will allow us to offer innovative programming to clients of all ages throughout our programs while also making a positive impact on the environment,” said Lenox Hill Neighborhood House Chief Planning Officer Laura Lazarus. “The space will be used by children in our Early Childhood Center to grow their own vegetables and learn about the plant life-cycle; by members of our Innovative Senior Center, the Center at Lenox Hill Neighborhood House, for horticultural therapy sessions; by the mentally ill homeless women from our Women’s Mental Health Shelter in the Park Avenue Armory and the older adults with dementia in our CARE Program for recreation and respite and much more. We are committed to providing our clients with the highest possible quality of supportive services and are thrilled to offer this tremendous resource to our clients.”
Like many older cities in the United States, New York City is largely serviced by a combined sewer system where stormwater, and wastewater from homes and businesses are carried through a single sewer pipe to treatment plants. During heavy rainfall, stormwater that falls on pavement, rooftops, and other impervious surfaces can exceed the capacity of the sewer system and a combination or stormwater and wastewater – called a combined sewer overflow (CSO) – can be discharged into local waterways. Since 2002, DEP has invested more than $10 billion in upgrades to wastewater treatment plants and related efforts to reduce CSOs and today New York Harbor is cleaner and healthier than it has been in a century. However, CSOs remain the city’s major harbor water quality challenge.
In 2010, the City launched the NYC Green Infrastructure Plan, an alternative approach to reducing CSOs and improving water quality that combines traditional infrastructure upgrades with cost effective green infrastructure installations that capture and retain stormwater runoff before it ever enters the sewer system. Over the next 20 years, DEP is planning for $2.4 billion in public and private funding for targeted green infrastructure installations, as well as $2.9 billion in cost-effective grey infrastructure upgrades, to significantly reduce CSOs. The Green Infrastructure Grant Program is one part of the Green Infrastructure Plan.
The Lenox Hill Neighborhood House is one of 29 different partners DEP has awarded funding to since the Green Infrastructure Grant Program launched in 2011. In total, DEP has awarded over $11 million to its Grant Program partners who, in turn, have contributed $5.3 million in matching funds. Notable projects that have completed construction include a 43,400 square foot rooftop farm at the Brooklyn Navy Yard and permeable pavers and rain gardens at Queens College. The winning projects were selected by an interagency Review Committee made up of representatives from the New York City Departments of Buildings, Design and Construction, DEP, Parks and Recreation, and the NYS Department of Environmental Conservation. Preference for grants was given to proposals that would provide cost-effective stormwater controls, matching funds or other contributions, and other benefits such as increased shade, decreased energy use for cooling buildings, increased awareness about stormwater management, and increased community stewardship.
In addition to funding green infrastructure projects through the Grant Program, DEP has begun an aggressive campaign to install bioswales and stormwater green streets - curbside gardens specially engineered to collect and absorb stormwater – in neighborhoods around the city. The installations resemble standard street tree pits but they are significantly larger, have curb cuts that allow stormwater to enter and exit, and are designed in a way that will allow each one to manage approximately 2,244 gallons of water during a storm. During construction they are excavated to a depth of five feet and are backfilled with layers of broken stone and engineered soil. These layers contain void spaces which store stormwater and promote infiltration. The addition of hardy plants encourages infiltration through root growth and increases the capacity of the bioswales through evapotranspiration. Thus far, DEP has installed 119 bioswales city-wide, hundreds more will be completed by the end of the year, and thousands will be added over the next five years.

To better understand the effectiveness of green infrastructure in managing storm water DEP has constructed three Neighborhood Demonstration Projects – clusters of bioswales in neighborhoods that drain into Newtown Creek, the Hutchinson River, and Jamaica Bay. The Neighborhood Demonstration Areas were developed in order to collect and analyze data on CSO volume reductions from green infrastructure projects, and the other associated benefits of the installations on a multi-block scale. The data collected from each of the three Demonstration Areas will then be extrapolated for calculating and modeling green infrastructure water quality and cost-benefit data on a waterbody and citywide basis. DEP also continues to collect data on a project-level basis to quantify the stormwater reduction from individual green roofs, blue roofs, bioswales, and other decentralized stormwater controls. Taken together, the Demonstration areas are expected to collect more than 7 million gallons of stormwater a year and keep it out of the combined sewer system.
Lenox Hill Neighborhood House, widely recognized as one of New York’s premier nonprofit organizations, is a 119-year-old settlement house that provides an extensive array of effective and integrated human services—social, educational, legal, health, housing, mental health, nutritional and fitness—which significantly improve the lives of 20,000 people in need each year, ages 3 to 103, on the East Side of Manhattan.
DEP manages New York City’s water supply, providing more than one billion gallons of water each day to more than nine million residents, including eight million in New York City. The water is delivered from a watershed that extends more than 125 miles from the city, comprising 19 reservoirs and three controlled lakes. Approximately 7,000 miles of water mains, tunnels and aqueducts bring water to homes and businesses throughout the five boroughs, and 7,500 miles of sewer lines and 96 pump stations take wastewater to 14 in-city treatment plants. DEP has nearly 6,000 employees, including almost 1,000 in the upstate watershed. In addition, DEP has a robust capital program, with a planned $14 billion in investments over the next 10 years that will create up to 3,000 construction-related jobs per year. This capital program is responsible for critical projects like City Water Tunnel No. 3 and the city’s Watershed Protection Program, which protects sensitive lands upstate near the city’s reservoirs in order to maintain their high water quality.
