GIS Access Introduction
The New York State Historic Preservation Office (SHPO) is a bureau of the New York State Office of Parks, Recreation and
Historic Preservation. The SHPO houses and maintains a broad range of information relating to historic properties in New York
State including historic buildings, structures, sites, districts, and objects. The SHPO includes in its mission a responsibility to
provide this information to municipalities, state and federal agencies, and the general public for the purposes of planning and
Two categories of information are available from the SHPO via the Internet in Geographic Information Systems (GIS) format.
These include 1) locational information on State and National Registers of Historic Places in New York State, and 2) Archeological
Sensitivity Zones for New York State. Both of these GIS resources are based on current records, databases, and file information
retained at the New York State Historic Preservation Office.
The State and National Registers of Historic Places GIS Database
The New York State and National Registers of Historic Places are the official lists of properties significant in the history,
architecture and archeology of the state and the nation. The database includes generalized boundary information for nearly 4500
individual properties and historic districts in New York State. Please note that Archeological Sites listed in the Registers are
protected under state and federal law and as such are not depicted on this site.
This site is updated on a quarterly basis, as such the information depicted may not include the most current information
regarding properties presently in the process of being nominated to the registers.
For legal purposes, the precise locations and boundaries are defined in the National Register of Historic Places Nomination
documentation on file at the SHPO or with the National Register of Historic Places office within the National Park Service,
Washington, D. C.
Archeological Sensitivity GIS Database
The Archeological Sensitivity Maps for New York State define areas within the state where the discovery of archeological
sites is predicted. These areas also contain the locations of all known sites that are included in the SHPO Archeological Site files
and the New York State Museum Archeological Site files. The exact locations are not displayed on this site since they are
protected from disclosure by Section 304 (16 USC 4702-3) of the National Historic Preservation Act of 1966 and Section 427.8 of
the implementing regulations for the State Historic Preservation Act of 1980. This information can only be accessed at the SHPO
in accordance with the SHPO's Policy on Access to Files, Data, and Information.
The site information depicted in this overlay reflects known sites protected by randomly placed buffer zones. These defined
sites with their buffer zones are used by the SHPO to provide recommendations to state and federal agencies regarding the need
for archeological surveys. This site is updated on a regular basis as a result the maps displayed may not be up to date and should
only be used as a reference tool. The depictions displayed on this site supercede all earlier versions of the Archeological
Sensitivity Maps for New York State.
The Appropriate use of SHPO GIS Database in Environmental Review
The information contained in the National Register and Archeological Sensitivity web pages can be useful to state and federal
agencies, municipalities, planning and engineering firms in the early planning stages of a project. The general information
contained in the State and National Registers of Historic Places web page can provide an early indication of the presence or
absence of Listed historic properties in or near a project area. The likely need for an archeological survey of a project area can
be ascertained by determining if the project is within a sensitive area on the Archeological Sensitivity Maps.
Accessing these GIS web pages cannot serve as a substitute for consultation with the SHPO for projects reviewed under
Section 106 of the National Historic Preservation Act of 1966 or Section 14.09 of the State Historic Preservation Act of 1980.
