Place 317 <> 000 cubic yards of sand fill, construct 

 2,200 feet of retaining wall and 2,200 feet of 

 submerged bulkhead, to form a beach between 71st 

 Street and 75th Street. 



The Chief of Engineers recommended adoption of projects by the United 

 States authorizing Federal participation in the first cost of protective and 

 improvement measures comprising groin construction and placement of sand 

 fill in Lake Bluff, groin construction in Lake Forest, Winnetka, and 

 Kenilworth, placement of sand fill, construction of jetties and riprap pro- 

 tection in Evans ton, aid the recommended beach construction in Chicago be- 

 tween Grace Street and Belmont Harbor, between 27th and li9th Streets and 

 between 5lst and 55th Streets, all substantially in accordance witii plans 

 outlined by the Beach Erosion Board, The recommended Federal contribution 

 was 1/3 of the first cost of construction of the projects for Lake Bluff, 

 Lake Forest, Winnetka, Kenilworth and Evanston and I/3 of the first cost 

 of the necessEirj. additional protection of the existing shore line in 

 Chicago, The Federal contributions were estimated at #11,300 for Lake Bluff, 

 19,200 for Lake Forest, #U,200 for Winnetka, $6,U00 for Kenilworth, $lU8,300 

 for Evanston, and |693,000 for Chicago. No Federa?. projects were recommended 

 for the shores between North Avenue and Oak Street and between 71st and 75th 

 Streets in Chicago, as the former does not require additional protection 

 and the existing shore in the latter is privately owned and thus not eligible 

 for Federal assistance under existing policy. The recommendation for Federal 

 aid was made subject to the conditions that responsible local authorities 

 will: (1) Adopt the aforementioned plans of protection and improvement, 

 subject to such modification as may be approved by the Chief of Engineersj 

 (2) submit for approval by -the Chief of Engineers detailed plans and 

 specifications and arrangements for prosecuting the work prior to commence- 

 ment of such work; (3) provide at tl-jeir own expense all necessary lands, 

 easements and rights- of -way; and provided further that responsible local 

 authorities give satisfactory assurances that they will; (a) maintain the 

 protective and improvement measures during their useful life, as may be 

 required to serve their intended purpose; (b) hold and save the United 

 States free from all claims for damages that may arise, either before, 

 d\iring, or after prosecution of the work; (c) not permit water pollution 

 that would endanger the health of bathers; (d) maintain continued public 

 ownership of the beaches and their administration for public use only,
