Regional Plan of New York and Environs (1922 - present)

Regional Plan of New York and Environs (1922 - present), or Regional Plan Association (abbreviated as RPA), is a nonprofit advisory organization founded by urban planners and civic leaders to develop comprehensive plans for infrastructure, transportation, zoning, and other aspects of urban planning in the New York City metropolitan area. Publishing its first regional plan in 1929, three subsequent plans followed in the 1960s, 1990s, and 2010s. Although the organization's focus has changed somewhat as the city has (adding, for example, a focus on preparing for climate change in recent years), it has consistently advocated for more affordable housing, greenspace, playgrounds, and mass transit, to improve the lives of residents of the city and its surrounding region. Despite not being a government body, the organization has had an influence on multiple projects in the New York City area, including the George Washington Bridge and the revitalization of both neighborhoods and greenspace in the city.
