the latter only if loss of fill is excessive, in lieu of the seven groins 

 proposed by the Beach Erosion Board, The Beach Erosion Board did not 

 consider the modification as effective as the recommended plan. However, 

 the Board considered the alternative a permissible substitute provided 

 satisfactory methods for maintaining the beach are adopted. 



The Board recommended that a project be adopted by the United 

 States authorizing Federal participation by the contribution of Federal 

 funds in an amount equal to one-third of the cost of the following pro- 

 posed works for shore protection and improvement: 



a. At Narragansett Pier, widening the beach between Upper 

 Pier and Narrow River an avera^je of about 125 feet by direct placement 

 of sand and constructing seven impermeable groins and a barrier to 

 landward sand movement; 



b. It Point Judith Harbor, widening the beach for a length 

 of about one mile west from the east limit of the State beach an 

 average of about 65 feet by direct placement of sand, constructing a 

 barrier to landward sand movement, and if experience indicates the 

 necessity, construction of ten impermeable groins; 



c. At Napa tree feach, constructing a barrier to landward 

 sand movement, and, if experience indicates the necessity, construction 

 of three impermeable groins. The proposed artificial replenishment of 

 Napatree ftach has been accomplished in connection with the disposal 



of dredged material from a navigation project. 



The Board recommended contribution of Federal funds subject to 

 the conditions that responsible local interest will: (1) adopt the 

 recommended projects, or in the case of Narragansett Pier, adopt the 

 plan for artificial beach building with such maintenance methods as 

 they desire in lieu of the groin system, subject to approval thereof 

 by the Chief of Engineers; (2) assure maintenance of the improvement 

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

 to serve their intended purpose; (3) provide at their own expense, all 

 necessary lands, easements, and rights-of-way; (4-) hold and save the 

 United States free from all claims for damages that may arise either 

 before, during or after prosecution of work; (5) assure that water 

 pollution that would endanger the health of bathers will not be ^per- 

 mitted; (6) assure continued public ownership of the beach and its 

 administration for public use only. 



In addition the Board recommended that the adequacy of work pro- 

 posed by local authorities, detailed plans, specifications, assurances 

 that the requirements of local cooperation will be met and arrange- 

 ments for prosecuting the entire project be approved by the Chief of 

 Engineers prior to commencement of work. 



The estimated costs of the work recommended by the ^ach Erosion 

 Baard for the publicly owned shores are as follows: Narragansett
