effectiveness because of deterioration o The aggregate length of the 

 bulkheads is about one mile almost all of which is located on Bradenton 

 Bsachj, the critical area„ These bulkheads afford protection against 

 ordinary storms, but portions are inadequate for extreme storms „ 

 There are no protective stinictures on Longboat Keyo 



The purpose of the Board's study was to determine the best method 

 of preventing further erosion and of stabilizing the beacheso The 

 Board reviewed the physical history of the area, and studied the winds, 

 currents, and wave action, changes in hydrographic detail, movement 

 of beach material, and effect of storms on the shore = The Board con- 

 sidered several plans of improvement, particularly for Bradenton 

 feach where protective measures are considered necessary at this timeo 



The Board concluded that the most effective method of accomplish- 

 ing the stated objectives for tiie critical area of Bradenton feach 

 would comprise artificial supply by direct placement of material in 

 position on the beach with periodic replenishment as required, and 

 re.tardation of its rate of erosion by installation of a system of 

 impemeable groins at an estimated first cost of not less than f 350, 000. 

 The Baard is of the view, however, that this method would require ex- 

 penditure of more funds "than local interests would consider Justifi- 

 able o In view of this consideration the Board believed that the most 

 practicable method of accomplishing in part the purpose of the study 

 is by artificial supply of material to the beach by operation of a 

 small hydraulic dredge on a continuing basis at an estimated annual 

 cost of from $15,000 to $25,OOOo The Board recommended that local 

 interests consider the foregoing methods of protection o Should 

 future development of Longboat Key warrant protective measures, 

 similar means of beach stabilization may be employed o 



Public Law 727, 79th Congress, approved 13 August 194-6, declar- 

 ed it to be the policy of the United States to assist in the con- 

 struction, but not the maintenance, up to one-third the cost of 

 works for the improvement and protection of coastal shores of the 

 United States that are owned ty States, municipalities, or other 

 political subdivisions o In the instant case all shore property is 

 in private ownership » 



In accordance with statutory requirements the Bbard reported its 

 opinion that adoption of a Federal project for protection of Anna 

 Maria and Longboat Keys is not advisable, that no public interest is 

 involved in such protection, and that no part of the expense involved 

 should be borne by the United States o
