The funds requested for fiscal year 1965 are required for orderly construction progress to meet scheduled completion dates. Comparison of Federal cost estimates.-The current Federal cost estimate of $9,400,000 is an increase of $100,000 over the last estimate presented to Congress. This change includes an increase of $83,400 for higher price levels and $16,600 in engineering and design and supervision and administration based on a recent reanalysis of requirements. Summary construction program (PB-1), fiscal years 1964 and 1965 Location and description.-Located on the Oregon coast about 50 miles south of the mouth of Columbia River. The rehabilitation project consists of rebuilding the north jetty, a rubble stone structure, 5,700 feet long, which protects the 18-foot bar and entrance channel. The existing structure was completed in 1917 with a top elevation of 14 feet above mean lower low water and a length of 5,400 feet. Subsequently, during the period 1931 to 1933 the jetty was rehabilitated and lengthened to 5,700 feet. Latest maintenance on the jetty was repair of a small break near the shore line in September 1955. Authorization.-Rivers and Harbors Acts of 1912 and 1913. Present condition.-About two-thirds of the jetty has subsided below the top elevation of 14 feet above mean lower low water. The outer 2,300 feet have subsided to below high tide level including about 700 feet that are below mean lower low water. Storm waves overtop the existing structure and cause additional damage to the rubblemound. Status (January 1, 1964).—North jetty, 19 percent completed. Completion schedule.-October 1964. Justification.-A number of commercial fishermen have their vessels based at Garibaldi and Bay City. Adjacent offshore fisheries also attract other fishermen who obtain fuel and supplies in the Tillamook area. All are dependent upon the project channels for safe navigation. The small boat basin completed at Garibaldi in August 1958 accommodates up to 150 fishing and pleasure craft during the peak of the fishing season. The subsidence of the north jetty creates a navigational hazard for small craft and subjects these vessels to extended attack by dangerous ocean waves. Barging of timber products existed when the jetty was in good repair. Commerce has declined as the jetty deteriorated until no timber products have been shipped since 1959. Restoration of the north jetty would help to stabilize the entrance channel and permit barging of an estimated 150,000 tons of timber products processed in the area annually. Fiscal year 1965.-The requested appropriation of $500,000 will complete the project and will be applied as follows: Comparison of Federal cost estimates.-The current estimate of $2,030,000 is a decrease of $110,000 from the latest estimate ($2,140,000). The decrease is due principally to favorable bidding. Summary construction program (PB-1), fiscal years 1964 and 1965 GRAYS HARBOR AND CHEHALIS RIVER, WASH.-SOUTH JETTY (Initiation of rehabilitation) Location and description.-At the entrance to Grays Harbor on the Washington coast, 45 miles north of the Columbia River. The rehabilitation consists of restoring the south jetty from about station 110 to station 150. The south jetty was originally constructed from station 72 to station 209 (13,700 feet) during the period 1898 to 1902. The jetty was reconstructed during the period 1935-39 to a top elevation of 20 feet above mean lower low water. Authorization.-1896, 1910, and 1935 River and Harbor Acts. Present condition.-From the landward end, at about station 80 to station 110, the jetty is in good condition. The outer 9,900 feet of jetty is in various stages of deterioration as follows: Station 110 to 150 (4,000 feet): Top elevation generally above mean lower low water but with foundation severely undercut. Station 150 to 198 (4,800 feet): Top elevation varying from mean lower low water to 5 feet below mean lower low water. Station 198 to 209 (1,100 feet): Severely damaged with little of the rock remaining in position. Status (January 1, 1964).-Construction not started. Completion schedule.-South jetty (stations 110 to 150), June 1966. JUSTIFICATION Repairs to south jetty between stations 110 and 150 should be initiated at an early date to preserve the existing undisturbed portion of the jetty landward of station 110, and to prevent further destruction in the portion of the jetty between stations 110 and 150 where the present rate of progressive deterioration is greatest. The jetty is essential to the retention of the self-maintaining deepdraft navigation channel through the entrance bar. Jetty deterioration results, in part, from a movement of the entrance channel, through natural causes, from a central location between the jetties to one adjacent to the south jetty. Swift ebb currents are undercutting and eroding the foundation material beneath the channel toe of the south jetty. Unless this undercutting is stopped soon, it will cause material loss of this portion of the jetty and require excessive reconstruction expenditure, rather than the rehabilitation costs now proposed. Early rehabilitation will permit salvage of most of the existing rock landward of station 150. (Rehabilitation of the submerged outer portion of the south jetty between stations 150 and 209 is deferred for further study.) Traffic through the entrance channel during the calendar year 1962 totaled 517,380 tons, as compared to the 10-year average tonnage of 498,386 tons. The tonnage consists primarily of petroleum products inbound and forest products outbound. During 1962, outbound cargo totaled 288,831 tons, and inbound cargo 228,549 tons. The commercial fishing fleet operates through the channel on a daily basis whenever weather permits. During the summer, thousands of recreation and charter craft also utilize the protection afforded by the facilities. Fiscal year 1965.—The requested appropriation of $500,000 will be applied as follows: Initiate rehabilitation of south jetty between stations 110 and 150---- Supervision and administration___. $380,000 80, 000 40,000 500, 000 Comparison of Federal cost estimates.-The current Federal cost estimate of $4,770,000 is the same as the latest estimate submitted to Congress.

Turning now to Operation and maintenance, General, we shall insert the justifications in the record at this point. (The justifications follow :) 1. Navigation JUSTIFICATION OF ESTIMATE (a) Channels and harbors.-The budget estimate of $6,540,000 provides for essential maintenance work on 23 channel and harbor projects named in the list which follows. The work to be accomplished under this activity consists of maintaining the navigation channels and harbors of costal harbors by means of dredging, removal of navigation obstructions, and repair of navigation structures, as authorized in the laws adopting river and harbor projects. (b) Locks and dams.-The budget estimate of $685,000 provides the amount for operational requirements of two projects. Annual requirements are for operation and ordinary maintenance of project facilities; labor, supplies, materials, and parts required for the day-by-day functioning of projects; and periodic maintenance, repairs, and replacements.
