Open Space Index

In 2010, NY4P developed the Open Space Index (OSI) methodology, which is based on a set of 15 NYC-specific benchmarks against which we measure open space maintenance, access, variety and environmental sustainability, generating data on the study neighborhood’s strengths and needs.

Mott Haven, the Bronx (2014)

The South Bronx’s Mott Haven neighborhood failed 11 of 15 benchmarks in this comprehensive assessment of both traditional Parks Department properties and New York City Housing Authority open spaces. The report calls for capital investment in parks and playgrounds, more welcoming and accessible Housing Authority spaces, and better access to the waterfront and Randall’s Island Park, among other improvements. Mott Haven is located within the poorest community board district in the city and poorest congressional district in the country. Funding for the report was provided by the Charles H. Revson Foundation, the Local Initiatives Support Corporation, and New York City Council Speaker Melissa Mark-Viverito. Read the report here.

East Side, Manhattan (2013)

New York City Council Districts 4 and 5 fall far short of nearly every one of the 15 New York City-specific benchmarks that comprise NY4P’s Open Space Index (OSI) – even when Central Park and Privately Owned Public Spaces are taken into account. In addition to the findings, our fourth OSI survey offers preliminary recommendations for East Side open-space improvements, including reimagining underutilized public spaces, pairing new development with open space improvements, and realizing the full potential of the East River waterfront. The report is based on hundreds of hours of on-the-ground surveying and analysis of more than 350 blocks of Manhattan, including Roosevelt Island. New York City Council Members Daniel R. Garodnick (District 4) and Jessica A. Lappin (District 5) provided funding for the study after learning that their districts rank near the bottom citywide for open space per capita.

East Harlem, Manhattan (2012)

The East Harlem Open Space Index is based on hundreds of hours of on-the-ground surveying and data analysis, including a field survey of more than 250 blocks of East Harlem. We present current open space measures for the neighborhood, and compare those to citywide standards, finding that East Harlem is rich in play areas, courts, fields, and community gardens, but falls short of standards for the total amount of open space per resident. The report offers preliminary recommendations to guide the future of the area’s open spaces, including maximizing public use of existing open space – the more than 100 acres of inaccessible New York Housing Authority lawns, for example – and better connecting people to parks. This is the first in a series of joint research reports conducted by NY4P and Mount Sinai School of Medicine Children’s Environmental Health Center. The report was made possible in part through funding from the Aetna Foundation Read the report here.

The Open Space Index Report, Including a Pilot Assessment of the Lower East Side, Manhattan (2010)

This report establishes the 15 Index standards and provides a detailed methodology for assessing open space in New York City neighborhoods. We piloted the OSI methodology on the Lower East Side of Manhattan, which was chosen because of its variety of open spaces, rich residential diversity and vibrant history of park and garden advocacy.   The pilot found that the Lower East Side performs very well with regard to community gardens, acres of active recreation, and access to parks. It also found, however, that the neighborhood has an urban tree canopy cover of only 14%, far below the US Forest Service’s 44% recommendation for that community. And the assessment found that the Lower East Side parks have very little green, natural ground surfacing within its parks. Read the report here.

Jackson Heights, Queens (2010)

Our second OSI  survey focused on the Jackson Heights neighborhood in Queens. The assessment found that Jackson Heights is severely lacking in open space compared to citywide standards. Local groups and elected officials have since used the findings, along with our 2009 City Council District 25 Profile, to advocate for park and open space improvements in the district.
