DOCUMENTARY HISTORY OF THE FLORIDA CANAL of the enormous cost of building and maintaining additional highway bridges at the cost of the people of the State. Such costs, coming after the canal has been completed, will retard the development of the island of Florida. The flooded valley of the Oklawaha will present a serious obstacle to any highway crossing that valley. 5. The engineers now making this joint statement do not believe that the low- est unit construction costs can be reasonably expected for the project, and for argument submit that: (a) Florida does not have within its borders all the necessary skilled and common labor to man the project. The interstate railways of Florida continu- ally bring from without construction and maintenance labor. The labor and mechanics to be employed on the project will necessarily be subject to the work- ing conditions and rates of pay which prevail in the United States, plus trans- port costs A project of such magnitude will involve the costs of sanitary and medical care for the employees. (b) Florida does not have much stone or gravel that will pass the customary specifications for hardness and toughness required for masonry specifications. Much of the coarse aggregate must be brought into the State. Florida has but few deposits of fine aggregate suitable for masonry, although there is much sand and sandy loam throughout the State. Much of the other construction mate- rials must come from beyond the State. (c) Florida does not have large local contracting organizations capable of handling any considerable part of the proposed work, and unit costs reported by the industrial plants in Florida since 1929 will be misleading if literally applied in the estimates of cost for the proposed work. (4) In fixing total construction cost of the work, consideration must be given to the shorter legal hours of service that may govern a project of this magnitude. 6. On the basis of $300,000,000 cost, not including any interest during con- struction or development period, the project must earn annually a sum of money to provide for the following: (a) Interest on construction cost. (b) Taxes and public dues. (c) Credit for necessary additions and betterments, as and when traffic requires such improvements. (d) Maintenance of the property so created and for administration, opera- tion, and sanitation. (e) Reasonable profit on undertaking. (f) Amortization or sinking fund. In regard to these listed items, we can reasonably at this time point to two of them: (a) 5% percent interest on $30,000,000.--------------------$1- 500,000 (b) Taxes and public dues------------------ __--- ----- -- 3,000,000 Sum of above two items---.------.-----.--.-----.- -- 19,500,000 In fixing the 5%-percent rate for interest, we follow the present rates of the Reconstruction Finance Corporation. Discussing the remaining items ((c) to (f) inclusive) we do not suggest what the cost of maintaining the completed project will be other than to point out the cost shown by the report of the Governor of the Panama Canal for the fiscal year 1982. Selecting those items that are applicable for comparative purposes, it appears that, on the Panama Canal basis, the annual operating expenses for the Gulf-Atlantic project as hereinabove described, may be ap- proximately $17,000,000. Neither of the two items ((a) and (b) above) in- clude amortization or depreciation, nor provide a sinking fund. The Panama Canal depreciation for fixed property for 1982 was $1,006,624. It is, there- fore, clear the $19,500,000 above cited is the minimum which this canal must currently earn, omitting consideration of the other listed items ((c) to (f) inclusive). 7. In explanation of item for taxes and public dues (b), $3,000,000, we say that the capital available in the United States all comes now from the United States. When any portion of the capital is invested, that sum is lost as a source of taxation unless provision be made for a tax revenue from the project, hence the above inclusion (b). We do not overlook the requirement of section 16, article 16, Florida Constitution, reading:
