Expanded Project for Aquatic Plant Control

EXPANDED PROJECT FOR AQUATIC PLANT CONTROL
CONDITION OF IMPROVEMENT, 30 SEPTEMBER 1987

Project
The River and Harbor Act of 3 July 1958, House Document 37, 85th Congress, lst session as amended by Act of 23 Oct 1962, Public Law 87-874, 87th Congress, 2nd session, and modification of 1965, Act 27 Oct 1965, Public Law 89-293, 89th Congress, 2nd session authorized a comprehensive project for controlling aquatic vegetation in the United States.

Purpose
To provide for control and progressive eradication of obnoxious aquatic plant growths from navigable waters, tributary streams, connecting channels and other allied waters of the United States in the combined interest of navigation, flood control, drainage, agriculture, fish and wildlife conservation, public health and related purposes; also continued research for development of the most effective and economic control measures.

Progress of Work
The State of Louisiana, Louisiana Department of Wildlife and Fisheries, furnished assurance of local cooperation which was approved and accepted on 24 March 1980. Under provisions of a continuing contract for an indefinite period of time, the local agency will perform work-in-kind approximating 50% of the program.

Most principal waterways and major bodies of water in the State of Louisiana have been brought under control so far as surface aquatic vegetation is concerned. Corps and State operations on this type of vegetation now are of a maintenance nature, with schedules being dictated by conditions and necessity. In 1986-1987, a normal winter kill, low water drying, and normal salt water intrusion into coastal areas have produced increased effective maintenance with better control of water hyacinth and allowed more extensive control operations in additional aquatic areas. The submerged aquatic weed, Hydrilla Verticillata continues to spread and efforts have begun to control this species. The floating fern, Salvinia Minimia, is increasing in acreage and will become a problem soon.

The Corps of Engineers performs control operations in the Lafourche drainage basin, Port Allen- Morgan City Waterway area, Teche drainage basin, and the Vermillion-Mermentau drainage basin. Occasionally, Corps crews are called on to supplement State control operations, which are in the Pontchartrain-Maurepas drainage basin, Atchafalaya drainage basin, Calcasieu drainage basin, Red River drainage basin, northern parts of the Teche drainage basin, and isolated lakes and streams in the northern half of the state. The New Orleans District, through work by the State of Louisiana, has accomplished control operations for the Vickburg District and Galveston District on the Pearl River basin and the Toledo Bend Reservoir, respectively.

A program was initiated in 1980 to treat submerged aquatic weeds in waterways of south Louisiana. This program has been expanded through 1987 to increase acres treated, which are mainly infested with hydrilla. Many waters which were previously clogged with submerged aquatics are now open to navigation.
Operations under 1965 River and Harbor Act were initiated in fiscal year 1968.

CONDITION OF IMPROVEMENT, 30 SEPTEMBER 1993

AUTHORIZATION :
The project was authorized by the River and Harbor Act of 1956, the Water Resources Development Act of 1976, and the Water Resources Development Act of 1986.

PROJECT :
The plan of improvement consists of four basic items: (1) a completed channel extending from the Inner Harbor Navigation Canal to the minus 38-foot contour in the Gulf of Mexico; (2) completed jetties and dikes along the channel in Breton Sound; (3) a new lock with connecting channels is pending a decision to initiate construction; however, planning for the new lock is continuing and (4) foreshore protection along the north and south side of the ship channel extending form the Inner Harbor Navigation Canal to the end of the hurricane protection levee.

LOCAL COOPERATION :
Assurances of local cooperation of items 1, 2, and 4 above were furnished by the Board of Commissioners of the Port of New Orleans and were accepted on behalf of the United States on 29 August 1957. The Board of Commissioners executed amended assurances covering the provisions of the Uniform Relocations Assistance and Real Property Acquisition Policies Act of 1970, Public Law 91-646, which were accepted on behalf of the United States on 21 April 1975 for the new lock. Supplemental assurances reflecting the changes made necessary by enactment of the Water Resources Development Act of 1976 were requested on 11 September 1978. By letter of 18 September 1978, local interests stated that they could not respond to our requests because plans for the lock at the Inner Harbor Navigation Canal site were in a very preliminary stage. In November 1983, the Board of Commissioners was informed of the selected plan and its costs, including their share, based on traditional cost sharing. By letter of 17 February 1984, the Board stated that it could not support the plan at that time because of the uncertainty of cost sharing and the financial situation of the State of Louisiana. However, by letter dated 11 February 1985, the Governor of Louisiana provided the necessary assurances to proceed with the coordination of an appropriate course of action for public involvement and to process the Evaluation Report. The public involvement program is being initiated consistent with the Evaluation Report schedule. The Shiplock will be cost shared in accordance with the provisions of Section 844 of the Water Resources Development Act of 1986, PL 99-662.

PROGRESS :
Work on the channel was initiated 17 March 1958. The construction of the channel is completed and is maintained at a depth of 36 feet. The extension of the Southwest Jetty to mile 14.8 is completed. The foreshore protection along the north side of the Inner Harbor Navigation Canal and the south side of the MRGO from Bayou Bienvenue to the end of the hurricane protection levee is complete. The remaining foreshore protection is on hold until the need arises. The existing lock was completed in 1923, by non-Federal interests, and had been leased by the Federal Government since 1944. On I July 1986, the lock, adjacent land, and facilities were purchased from the Board of Commissioners of the Port of New Orleans for $3,800,000. By purchasing the lock, the Corps received fee title to the lock and appurtenances with operation and maintenance responsibility for the St. Claude and Florida Avenue Bridges transferring to the Board of Commissioners of the Port of New Orleans. A General Re-evaluation Report is presently being prepared for a new lock and connecting channels. The final site and size for the new lock has not been determined. The report is scheduled for completion in 1995.

MISSISSIPPI RIVER OUTLETS, VENICE, LA
CONDITION OF IMPROVEMENT, 30 SEPTERBER 1987

Project
The River and Harbor Art of 1968, approved 13 August 1968 (House Document 361, 90th Congress, 2nd Session), provides for additional navigation outlets from the Mississippi River in the vicinity of Venice, Louisiana, by enlargement of the existing channels of Baptiste Collette Bayou and Grand Tiger Passes to provide channels 14 feet deep (Mean Low Gulf) over a bottom width of 150 feet, with entrance channels in open water 16 feet deep over a bottom width of 250 feet. Jetties, to the 6-foot depth contour, are authorized if and when justified to reduce the cost of maintenance dredging.

Purpose
To provide navigation access between Venice and the adjacent areas of the Gulf of Mexico, and to provide a shorter navigation route between the east and west waters of the Gulf.

Progress of Work
Assurances of local cooperation were furnished by the Plaquemines Parish Commission Council on 28 May 1970 and were accepted by the United States on 18 December 1970. The Council was requested to furnish Supplemental Assurances covering PL 91-646 in August 1973. Amended assurances covering FL 91-646 and FL 91-611 were received 5 August 1977.

The GDM was approved on May 29, 1975 subject to comments. The availability of the Environmental Impact Statement was published in the Federal Register September 30, 1976.

The enlargement of Baptiste Collette Bayou began in November 1977 and was completed in May 1978 and the jetty construction was completed in May 1979. The enlargement of Grand and Tiger Passes began in March 1978 and was completed in October 1978 and construction of the jetty was completed in March 1979.

Mississippi River Ship Channel Gulf to Baton Rouge, LA

MISSISSIPPI RIVER SHIP CHANNEL, GULF TO BATON ROUGE, LOUISIANA
CONDITION OF IMPROVEMENT, 30 SEPTEMBER 1997

AUTHORIZATION :
The project was authorized by the Supplement Appropriation Act of 1985, (Public Law 99-88 dated 15 August 1985). The Water Resources Development Act (WRDA) of 1986, (Public Law 99-662) provides for innovative cost sharing between the Federal Government and non-Federal interests for construction and maintenance of the project.

Project :
The Mississippi River Ship Channel, Gulf to Baton Rouge, La., project will provide more efficient deep draft navigation access to the New Orleans and Baton Rouge reaches of the Mississippi River via Southwest Pass by enlarging the existing channel to a project depth of 55 feet, enlarging the adjacent channel along the left descending bank in New Orleans Harbor to a 40 foot depth, constructing a turning basin at Baton Rouge, constructing training works in the passes to reduce maintenance dredging and constructing saltwater intrusion mitigation features which are required as a result of deepening the channel.

LOCAL COOPERATION :
A Local Cooperation Agreement (LCA) between the Government and the State of Louisiana was signed on 30 June 1986. The first supplement to the LCA was signed on 15 June 1987 to comply with the cost sharing and financing concepts ref lected in the WRDA of 1986. A second supplement to the LCA was signed on 25 June 1990 to incorporate language allowing relocation costs to be credited towards the 10% non-Federal repayment as per WRDA of 1988 and language disallowing the State to use any Federal funds for their cash contributions. The LCA and first supplement provide for cost sharing (75% Federal, 25% non- Federal) for dredging of a 45 foot channel from the Gulf of Mexico to mile 181.0 and the construction of saltwater mitigation features. This work is defined as Phase I. A third supplement to the LCA addresses construction of the saltwater mitigation features and was executed 28 May 1993. A Project Cooperation Agreement (PAC) for Phase II was executed on 3 September 1993. Phase II provides for the Dredging of a 45-foot channel from mile 181.0 to Baton Rouge.

Progress :
Phase I dredging construction was initiated on 1 July 1987. A 45 foot channel from the Gulf to mile 181.0 was complete in December 1988. An underwater sill at mile 64.0 was constructed in July 1988 as a mitigation measure to reduce saltwater intrusion during the drought conditions that year. Freshwater was also barged to three municipal water plants during 1988. Phase I mitigation construction (upgrades to the Plaquemines Parish water supply and distribution system on the west bank) was initiated after executing with the State of Louisiana on 28 May 1993 the third supplement to the LCA. When complete, barging freshwater will not be required.
Phase II dredging construction was initiated in July 1994. Construction involved deepening seven river crossings to 45 feet. Phase II was completed 9 December 1994.
The State of Louisiana has requested that Phase III investigation proceed on the remaining authorized project features. We are preparing a Federal Design Memorandum documenting the results of our investigations into deepening the river 50 to 55 feet.
