The map below shows the boundaries of the Prospect Heights Historic District as proposed by PHNDC and The Municipal Art Society of New York.
The red line is the proposed New York City historic district. The purple line shows the existing National Register District.

A PDF of the proposed district is available here.

Please note that on April 9, 2008 the New York City Landmarks Preservation Commission released draft boundaries for a study area of a Prospect Heights historic district. The LPC's boundaries, which are subject to change, are different than those proposed by PHNDC and MAS, and can be viewed here.
