The bonds may be issued in an amount not to exceed $4,000,000, and the proceeds appropriated to be used by the seaway port authority for any or all of the purposes specified in section 469.062, subdivision 2, if the county board by resolution determines that the conservation, development, reclamation, protection, and improvement of lands under the jurisdiction of the port authority and the construction of port facilities thereon will promote the public welfare of the county at large and the economic well-being of its people, industries, and commerce, and is an essential governmental function of the county, and can best be performed through the medium of the port authority.
