Metropolitan Waterfront Alliance

The Metropolitan Waterfront Alliance, a project of the MAS since 1999, is a network of more than 300 organizations dedicated to helping our region reclaim and reconnect with our greatest natural resource — the harbor, rivers and estuaries of the New York-New Jersey metropolitan area.

Streetscapes

Understanding that the streets and sidewalks of New York represent the city’s single largest public space, the MAS works closely with community groups, like-minded organizations and elected officials to make the city government recognize that our streetscapes are important and valued public amenities, and that they should be approached with the same passion applied to the planning of any public space.

The Planning Center

Helping community organizations and neighborhood advocates confront the planning, land use and economic development issues facing their neighborhoods is the core goal of the MAS Planning Center. Through public forums, workshops, publications and one-on-one assistance, the Planning Center tackles neighborhood issues at grassroots and citywide levels.

Urban Planning

Aggressively championing excellence in urban design, the MAS believes that the physical city — its light, air, land and open spaces — and its sensible development are critical to New York’s continued economic health and the well-being of its inhabitants.
