N.Y.C. Admin. Code § 5-338: § 5-338 Title acquired for streets; subject to certain easements.

If any individual or corporation, before the entry of the order granting the application to condemn, has acquired any easement for the purpose of laying or maintaining in the real property to be acquired for street purposes in a proceeding pursuant to this subchapter, underground pipes or conduits for the distribution of water, gas, steam or electricity, or for pneumatic service, such easement shall not be extinguished, but the title to the real property so to be acquired for the purposes authorized shall be taken subject to such easement; provided, however, that nothing herein contained shall be so construed as to limit the power of the city to acquire by purchase or by condemnation proceedings the entire plant or service of such individual or corporation, or to acquire such easement in such street in any other appropriate proceedings.
