In the late 1960s the land was annexed to the city of Halifax, but a proposed high-rise apartment met with protest from the Northwest Arm Community Planning Association. Though a counterproposal to rezone the site as parkland was rejected, development on Deadman's Island itself did not proceed. However, by the 1990s the land was "effectively the last piece of undeveloped waterfront land on the Northwest Arm." Condominium units were proposed in 1998, and were again met with protest from community associations. The Northwest Arm Heritage Association began a project to catalogue the prisoners buried on the site and was joined in their efforts by related societies throughout the Maritimes and
New England, culminating in a request that the municipality recognize Deadman's Island as a heritage property. The issue was broadcast internationally, receiving mention in
The Globe and Mail,
The New York Times and the
Boston Globe, among others. The city hired historian
Brian Cuthbertson to evaluate the heritage claim, and his report concluded that the site could hold as many as 400 bodies (in contrast with the 35 suggested by the developer's preliminary survey). The city also saw the site as a potential attraction for American tourists, much like the nearby memorials to victims of the
Titanic disaster. The development application was withdrawn in late 1998, and in February 2000
Deadman's Island Park was established by the
Halifax Regional Municipality to protect the site and commemorate its historic significance. A memorial service for the American Prisoners of War buried there was held 23 June of that year by members of the U S 164th Civil Engineering Sqn, Tennessee Air National Guard, Memphis, TN. They being the first U S Service Members to Honor those buried in unmarked graves there. A large plaque was installed on 30 May 2005 to memorialize the unmarked graves of the American servicemen. The plaque dedication was attended by an Honor Guard from USS Constitution in Boston. ==Deadman's Island Park==
