  The 
  estimated 
  cost 
  for 
  a 
  30-foot 
  channel 
  is 
  $208,448,000,

  the 
  mouth 
  of 
  the 
  

   Normans 
  kill 
  to 
  tidewater 
  at 
  New 
  York 
  would 
  require 
  some 
  work 
  

   to 
  be 
  done, 
  although 
  for 
  a 
  21-foot 
  channel 
  the 
  river 
  is 
  mostly 
  deep 
  

   enough.
