New York's Hudson River Greenway and the West Side waterfront benefit from prevailing westerly winds drawing relatively clean air off the Hudson River, providing better conditions than the dense street grid one block east. The open riverfront geometry prevents the pollutant accumulation typical of Manhattan's enclosed avenues.
