The following estimate of cost of dredging a channel 16 feet deep at mean low water and 400 feet wide through Fort Hale Bar-about 7,000 feet longis based upon the survey of 1886: Dredging 450,000 cubic yards of mud, at 9 cents..... $40,500 6,500 The total required for completion of the dike and for dredging on Fort Hale Bar is $93,000; to this should be added an estimate of $5,000 annually for maintenance of channels and for repair of dike. Appropriations for the improvement of New Haven Harbor have been made as follows, viz: New Haven, the port of entry for the collection district of New Haven, is situated at the head of New Haven Harbor, about 3 miles from Long Island Sound. There is a light-house on Southwest Ledge at the mouth of the harbor. Fort Hale, 2 miles below the city, commands the channel.

The importance of a harbor of refuge at the entrance to New Haven Harbor had been urged by memorials to Congress, and set forth in annual reports to the Chief of Engineers, when, March 3, 1879, the first appropriation was made for the construction of a breakwater. The subject was referred to the Board of Engineers for Fortifications and for River and Harbor Improvements, who presented to the Chief of Engineers their views upon the matter in a letter dated November 24, 1879, which is printed in full in the Annual Report of the Chief of Engineers for 1880, Part I, pages 448-156. This letter presents estimates for two breakwaters to form a harbor of refuge for vessels of 20 feet draught; the easterly break water, 3,300 feet long, to extend from the light-house on Southwest Ledge to Quixe's Ledge; the westerly one, about 4,200 feet long, to extend in a general northwesterly direction from Luddington Rock, its precise location and length not being determined. Both were to be of rip-rap granite, reaching 6 feet above mean high water, 12 feet wide on top, with outer slope of 1 in 3, and inner slope of 2 in 3; the average height of the east breakwater was estimated at 32 feet, of the west one, 28 feet, and their cost was estimated at: The letter of the Board of Engineers was submitted by the Chief of Engineers to the Secretary of War, with the suggestion that the appropriation' then available "be applied toward the construction of a breakwater from Light-House Ledge" (the east breakwater), which was approved by him January 31, 1880. A modification of the cross-section, making the outer slope 1 on 2 and the inner slope 1 on 1, was proposed by the officer in charge and approved by the Chief of Engineers, February 14, 1880, before work was begun. This would reduce the estimate for the east breakwater to $480,000, but as the location and length of the west breakwater are not yet fixed, its cost may be greater than was estimated, and it seems advisable to retain the total estimate first given, $1,311,134. Under this project up to July 1, 1886, 2,147 linear feet of the east breakwater were built, using 189,898 tons of granite and costing (supervision, etc., included) about $100 per linear foot. OPERATIONS DURING THE FISCAL YEAR ENDING JUNE 30, 1887. Under the appropriation of $75,000 made by act of Congress approved August 5, 1886, proposals were received and a contract, dated October 22, 1886, was entered into with T. J. Allen, of New York City, to deliver 57,000 tons of granite in the east breakwater at the rate of $1.12 per ton. Work was begun December 21, 1886, and up to July 1, 1887, 22,643 tons had been delivered, building 265 linear feet of the breakwater. Work is still in progress under this contract, which expires August 31, 1887. PRESENT CONDITION OF WORK. The east breakwater is now 2.412 feet long, being about three-quarters of its projected length of 3,300 feet. It contains 212,541 tons of granite and has cost (supervision, etc., included) about $100 per linear foot. PROPOSED OPERATIONS. In their report of November 24, 1879, submitting plans and estimates, the Board of Engineers expressed "the opinion that after the completion of a certain portion of the easterly breakwater the westerly one should be promptly commenced." About $65,000 will be required to finish the east breakwater. With future appropriations it is proposed, first, to complete the east breakwater and then to begin upon the west one. Should sufficient appropriation be made, work on both could be readily prosecuted at the same time. During the ensuing year $500,000 could be profitably expended in completing the east breakwater and beginning work upon the west one. Appropriations for the New Haven Breakwater have been made as follows, viz: New Haven, the port of entry for the collection district of New Haven, is situated at the head of New Haven Harbor, about 4 miles north of the breakwater. There is a light-house on Southwest Ledge, at the west terminus of the east breakwater. Fort Hale, 2 miles north from the breakwater, commands New Haven Harbor. Money statement.

The value of the cargoes of the vessels can not be ascertained; it is undoubtedly very great. D 7. IMPROVEMENT OF MILFORD HARBOR, CONNECTICUT. This harbor is on the north shore of Long Island Sound, about 9 miles southwest of New Haven, Conn. It consists of a broad, open bay, from the head of which a small tidal stream extends three-quarters of a mile inland to the Milford wharves. The original depth on the bar at the mouth of the river was 2 feet at mean low water, and in some places between there and the upper wharves low tide left the channel nearly bare. PROJECTS FOR IMPROVEMENT. In 1872 a "survey of breakwater at Milford, Conn.," was ordered. There being no break water, a survey of the harbor for a break water was made, and in the report, dated December 24, 1872, the following plan of improvement was submitted: 1. A rip-rap breakwater from Welch's Point, on the east side of the mouth of the harbor............. Superintendence. Total..... 4. A jetty on the east side of the channel to prevent the dredged area filling and to confine the action of the tide... 3. Dredging 4 feet deep and 100 feet wide across the bar at the mouth of the river 2. Protecting the bluffs on the east shore from erosion, by means of small stone jetties.. $67,000 5,500 6,250 5,000 1,250 85,000 |
