Defining custom projection using baseline survey coordinates


I have CAD data that I need to incorporate into a GIS analysis. The CAD data does not have a defined projection, but the drawings include a table of survey baseline points. I need to know if I can build a custom projection based on this table:


Survey baseline coordinates


Is this enough information to construct a custom projection string, or do I need more data?



The documentation references a "Borough of Queens Coordinate System", which turns up nothing in Google. My hope was that it's some obscure projection only used in New York City but that it could be recreated using the above table.
