Justification.-Several areas in the Saginaw Basin have experienced serious flooding on numerous occasions. Floods are of two types, those which are general through the whole basin and those which are limited to one or two of the main tributaries without serious rises on the others. General floods have a frequency of about once in every 6 or 7 years, whereas on any given tributary the frequency is about once in every two or three years. The most notable recent floods of a general nature occurred in April 1947 and March 1948, with damage to all the problem areas. Damages were about $4,280,000 for the 1947 flood and about $1,425,000 for the 1948 flood. A recurrence of these floods under present conditions would cause damages estimated at $8,165,000 and $2,825,000 respectively. The project plan will essentially eliminate these damages. Breakdown of average annual benefits Flood control___ Total $1, 122, 700 599,000 $1,721, 700 Fiscal year 1968.-The requested amount of $1,200,000 will be applied as follows: Funds requested for FY 1968 are required for orderly construction progress with completion as scheduled on the Flint Unit in June 1969. Non-Federal cost.-The cost to local interests in connection with construction of the authorized project is estimated at $4,760,000 broken down as follows: Local interests are required to maintain and operate the flood control improvements at an estimated cost of $107,000 annually. In addition, the City of Frankenmuth has constructed a pumping plant and levees at a cost of about $72,000. Extensive drainage and flood control improvements have been made in Shiawassee Flats and Flint, the costs of which are not available. STATUS OF LOCAL COOPERATION Flint.-Formal assurances of local cooperation from the Flint City Commission were accepted on 23 November 1962. The cash contribution was received on 20 February 1963. Rights-of-way are being furnished as required. Frankenmuth.-The City of Frankenmuth has complied with all requirements. Shiawassee Flats.-Local interests have held public meetings to determine ways and means of establishing a local governing body capable of furnishing the items of local cooperation. COMPARISON OF FEDERAL COST ESTIMATES The current Federal (Corps of Engineers) cost estimate of $20,000,000 is an increase of $600,000 over the latest estimate ($19,400,000) submitted to Congress. This increase is due primarily to higher price levels. Summary construction program (PB-1), fiscal years 1967 and 1968 Location. The project is located at St. Paul and South St. Paul, Minn., on right bank of the Mississippi River. Authorization.-1958 Flood Control Act. In addition, local interests at South St. Paul have expended approximately $1,000,000 to provide partial flood protection in the project area, and local interests at St. Paul have expended about $2,500,000 to provide flood protection in other areas. Interceptor sewers and outfalls (feet) 2 Total length of flood barrier, including levees, flood walls, closure structures, and high ground (feet). Justification.-The Mississippi River flood plain area to be protected by the project totals about 1,200 acres. In St. Paul, it contains numerous manufacturing industries, bulk oil storage depots, and retail business and residential districts. Damages at St. Paul at time of flooding amounted to $315,400 and $2,067,000 for the 1951 and 1952 floods, respectively. At present prices, under current conditions of development, damages from floods similar to these would amount to about $515,000 and $3,307,000, respectively, all of which would be prevented by the project. It is estimated that damages of about $10,000,000 were prevented by the completed project during the 1965 flood. These damages prevented by operation of the project under present conditions and at present prices would amount to $10,400,000. In South St. Paul, the flood plain area contains meat packing plants, stockyards, and sewage treatment plant. Damages at South St. Paul at time of flooding amounted to $1,802,000 and $874,000 for the 1951 and 1952 floods, respectively, damages in 1952 having been reduced because of locally constructed levee improvements. Under current conditions of development and at current prices, damages from a recurrence of the 1951 flood, including protection provided by an existing levee constructed immediately following the 1951 flood, would amount to $79,000. A recurrence of the 1952 flood, assuming failure of the existing levee and the sewage plant walls would amount to $10,477,000. During the 1965 flood, damages estimated at $14,600,000 would have occurred at South St. Paul except for flood-fighting efforts which under present conditions at present prices would amount to about $15,180,000. Emergency flood fighting costs were estimated at $900,000. These damages would be prevented if the project were in operation. Damaging floods occur on an average about every 4 years. The average annual flood control benefits for the two units are estimated at $255,200 for St. Paul and $477,800 for South St. Paul for a total of $733,000 for the project. Fiscal year 1968.—The requested amount of $1,754,000 will complete the project and will be applied as follows: Complete construction of levees, flood wall and pumping plants at Engineering and design. Supervision and administration_ Total $1,625, 000 18, 000 111, 000 1,754, 000 Non-Federal costs.-The initial investment required of local interests in construction of the authorized project is estimated at $1,572,000 broken down as follows: At South St. Paul, local interests constructed levees before the 1951 flood and during and following this flood they raised and strengthened them at a total cost of about $1,000,000. At St. Paul, the City has constructed flood protection works on the left bank of the river at a cost in excess of $2,500,000. Local interests are required to maintain and operate the project in both cities upon completion. It is estimated that the average annual expenditure for maintenance, operation, and replacement will total $15,900 for St. Paul and $20,800 for South St. Paul. Status of local cooperation.-Local interests in both St. Paul and South St. Paul have furnished assurances, land, and the cash contribution. Comparison of Federal cost estimates.-The current Federal cost estimate of $8,580,000 is the same as the latest estimate submitted to Congress. However, minor adjustments have been made in feature estimates. |
