Summary construction program (PB−1), fiscal years 1964 and 1965 Item SAVANNAH HARBOR, GA. (KINGS ISLAND Turning Basin) (Continuing) Location.-Savannah Harbor comprises the lower 21.35 miles of the Savannah River and 9.7 miles of channel across the bar to the Atlantic Ocean. The Kings Island turning basin in Savannah Harbor is located between miles 18 and 19 above the mouth of the river. Authorization.-River and Harbor Act of 1962. Benefit-cost ratio.-1.2 to 1. In addition, local interests have expended $225,000 to provide local cooperation requirements for previous modifications, and the Georgia Ports Authority recently completed expansion of their Garden City terminals, and improvements to the ocean terminals at cost of about $10,000,000. PHYSICAL DATA Turning basin : 34 feet deep, 900 feet wide, and 1,000 feet long. JUSTIFICATION Traffic in Savannah Harbor has increased steadily from 2,784,000 tons in 1949 to 4,558,411 tons in 1962. This trend is expected to continue throughout the life of the project. In the past, vessels have been turned away from the port due to limited berthing areas. However, the Georgia Ports Authority recently acquired additional waterfront property, and during 1963 completed expansion of its docking facilities. It is therefore reasonable to assume that the present volume of commerce will continue to increase as expanded facilities are utilized and additional commercial sites are developed. Benefits are based on reduction in delays to vessels awaiting favorable tides for turning. The existing turning basin is inadequate for present traffic and large vessels cannot navigate except under favorable tidal conditions. Principal items of commerce moved during calendar year 1962 were petroleum products, gypsum rock, sugar, naval stores, wood pulp, paper, and fertilizer materials. Petroleum products amounted to 2,408,982 tons, gypsum rock 313,866 tons, and sugar 225,564 tons. A considerable quantity of fuel for military aircraft is brought into the harbor where storage facilities are available at the State port. Completion of Kings Island turning basin in Savannah Harbor is essential to eliminate costly delays experienced by the present traffic and for future growth of the harbor. Fiscal year 1965.-The requested amount of $340,000 will be used as follows: Complete dredging of turning basin. Supervision and administration___ Total $316, 000 24, 000 340, 000 Requested funds are required for completion of a continuing-type dredging contract which is to be awarded during fiscal year 1964 and will permit completion of the project about September 30, 1964. Completed modifications.-The existing project consists of channels 36 by 500 feet across the ocean bar and 34 by 400 feet and 30 by 200 feet in the rivers and four turning basins. The dimensions of the existing Kings Island Basin are 34 by 600 by 700 feet. Construction cost of completed work is $16,298,000. Remaining modifications.-None. Non-Federal costs.-The cost to local interests of complying with the requirements of local cooperation as set forth in the authorizing legislation for the Kings Island turning basin is estimated to be $79,000. This cost to local interests will be to: (a) Provide, free of cost to the United States, all lands, easements, and rights-of-way, including spoil disposal areas and necessary retaining dikes, bulkheads, and embankments therefor, required for the construction of the project and for subsequent maintenance when and as required. (b) Agree to hold and save the United States free from damages due to the construction and maintenance of the project. (c) Provide and maintain at local expense adequate public terminal and transfer facilities open to all on equal terms in accordance with plans approved by the Chief of Engineers where appropriate. Local interests also incurred cost of $225,000 in complying with the requirements of local cooperation for previous work accomplished on the project. A terminal facilities expansion program was initiated in 1960 by the Georgia Ports Authority. The improvements to the Garden City terminals and improvements to ocean terminals were recently completed at cost of about $10 million. Status of local cooperation.-The commissioners of Chatham County, Ga., on July 21, 1961, resolved to act as local assurer and secure necessary spoilage ease ments and construct spoil dikes in Savannah Harbor for the Kings Island turning basin. Local assurers have obtained necessary easements and construction of spoil dikes will be commenced about January 1, 1964. Comparison of Federal cost estimates.-No change from the latest estimate submitted to Congress. Summary construction program (PB-1), fiscal years 1964 and 1965 Location.-Pascagoula Harbor is located on Mississippi Sound, an arm of the Gulf of Mexico, 32 miles west of the entrance to Mobile Bay, Ala. Authorization.-1962 River and Harbor Act. 1 In addition, local interests have expended an estimated $10,000,000 for public terminal and transfer facilities. Planning is underway for additional public terminal facilities estimated to cost $3,000,000. PHYSICAL DATA Channels: Across bar at Horn Island Pass 40 feet deep, 350 feet wide. Across Mississippi Sound and up Pascagoula River to Louisville & Nashville Railroad bridge 38 fet deep, 350 feet wide. From main channel in Mississippi Sound to Bayou Casotte 38 feet deep, 225 feet wide. In Bayou Casotte 38 feet deep, 300 feet wide. Turning basins: West side of channel below Louisville & Nashville Railroad bridge 38 feet deep, 950 feet wide, 2,000 feet long. Head of channel in Bayou Casotte 38 feet deep, 1,000 feet wide, 1,750 feet long. A significant increase in deep-draft commerce is expected at Pascagoula Harbor due to operation of the Jackson County terminal elevator which was completed in September 1961. Over 900,000 tons of soybeans and grains were exported from this elevator in 1962 and 1963 shipments totaled about 2,053,700 tons. Most of this grain is shipped to Western Europe and, due to limitations imposed by the existing channel, moves in relatively small general cargo vessels and tankers. In view of the trend toward the use of supertankers and bulk carriers in the export grain trade, however, and the lower transportation costs resulting therefrom, it is expected that at least 60 percent of the future grain exports from Pascogoula will move in these larger vessels if adequate channel depths are made available. At loaded drafts of about 34 feet, these vessels would require a channel depth of about 38 feet to insure adequate clearances from trim squat and maneuverability. The enlarged channel also will permit the local shipyard to construct and repair the POLARIS class of nuclear-powered submarines. Chrome ore and phosphate rock are shipped to fertilizer and refractory manufacturers, located on Bayou Casotte, in deep-draft vessels. In addition to this, the Standard Oil Co. has constructed a large oil refinery in the Bayou Casotte industrial area which went into operation in September 1963. This refinery will use deep-draft vessels for the movement of about 450,000 tons of inbound crude oil annually, and for the coastwise shipment of about 2,918,000 tons refined products. It is expected that all of this crude oil, and about 50 percent of the refined products, will move in supertankers of 33,000 to 35,000 deadweight tonnage because of the significant savings in transportation costs that results from use of these large vessels. These large tankers have a loaded draft of 34 feet 6 inches and therefore require channel depths of at least 38 feet in order to operate safely at full loads. Under existing conditions at Pascagoula Harbor and Bayou Casotte, only the smaller tankers could be used safely in the movement of petroleum and petroleum products. Fiscal year 1965.-The requested amount of $620,000 will be utilized as follows: Initiate and complete outer bar dredging- $550,000 70, 000 620,000 Total____ Funds requested will complete the project. COMPLETED MODIFICATIONS Completed modifications were authorized by the 1913, 1915, 1954, 1958, and 1960 River and Harbor Acts. The existing project was completed in June 1962 and provides for a channel 38 by 325 feet across the outer bar at Horn Island Pass; thence 33 by 275 feet across Mississippi Sound to the Pascagoula River: thence 33 by 275 feet to the railroad bridge at Pascagoula; a turning basin 33 by 950 by 2,000 feet below the railroad bridge. A channel from the railroad bridge 22 by 150 feet up the Pascagoula and Dog Rivers to State Highway 63 bridge over Dog River; thence 12 by 125 feet through Roberston and Bounds Lakes to mile 6.0 on Dog River. A channel 30 by 225 feet from Mississippi Sound to Bayou Casotte; thence 30 by 300 feet in Bayou Casotte terminating at a turning basin 30 by 1,000 by 1,750 feet. The total Federal cost of the completed work is $2,549,000. Non-Federal cost.-The cost to local interests of complying with the requirements of local cooperation as set forth in the authorizing legislation for the 38foot channel is $45,000. This cost to local interests consists of dredging slips in berthing areas and retaining dikes. In addition, local interests have expended an estimated $10 million for public terminal and transfer facilities. Planning is underway for additional public terminal facilities estimated to cost $3 million. Status of local cooperation.-The Jackson County Port Authority and Jackson County Board of Supervisors are the responsible cooperating agencies. Satisfactory assurances have been furnished. Required spoil disposal areas and retaining dikes have been provided. Depths in berthing areas commensurate with depths being provided in the related project areas will be available prior to completion of the channels. Comparison of Federal cost estimates.-The Federal cost estimate of $3.520.000 is a decrease of $1,380,000 from the latest estimate ($4,900,000) submitted to Congress. Decrease in dredging cost of $1,220,000 was due to reduction in yardage based on recent survey and favorable bid on pipeline dredging. Engineering and design and supervision and administration costs were also reduced. Summary construction program (PB-1), fiscal years 1964 and 1965 PALM BEACH COUNTY, FLA. (LAKE WORTH INLET TO SOUTH LAKE WORTH INLET) (Reimbursement-Continuing) Location.-Palm Beach, Fla., is on the coastal barrier island by that name on the east coast of Florida, about 300 miles south of Jacksonville and 70 miles north of Miami.
