The goal of this petition to the Governor of New Jersey, to the
> Mayor of Holmdel, and to the new owners, is to secure the
> preservation of this site and its public access in the future.
Neither the Governor nor mayor would have anything to do with this. It's basically up to the new owners and perhaps the sellers. Who are the sellers? (Lucent?)
It may be rather expensive for the new owners to revise their plans to preserve the monument; that would be after all wasted space and possibly interfere with the design of buildings for the site. Providing public access to the site will definitely be expensive since in today's world there are significant security and liability considerations. In the end, you may be asking too much from the new developers.
In cases like this, sometimes monuments have to be relocated. It may be better for all to move the monument to the nearest public park.
