a. Ihe adopted program of artificial nourishment has re- 

 stored the beaches east of Santa Efeirbara Harbor to a condition approach- 

 ing stability, but, in some places, on an alignment considerably 

 shoreward of its 1929 position, and that natural processes leave but 

 little sand on many of the beaches for extended periods; 



bo The intermittent pumping of sand to the feeder beach 

 by floating plant in connection with harbor maintenance has been satis- 

 factory and shovild be continued until replaced ty an equally effective 

 means of supplying sand to the beaches. The adopted biennial period 

 for dredging has been satisfactory to prevent depletion of the supply 

 on the feeder beach; 



Co The location of the feeder beach beyond the sheltering 

 effect of the breakwater has been satisfactory for the purpose. The 

 most desirable length of fill is such that the stockpile will not be 

 depleted entirely during the period between filling operations, nor 

 result in excessive widening of the feeder beach; 



do Available data are insufficient for reconsideration of 

 the design for a fixed sand-pumping plant, but that such a plant 

 would provide more advantageous use of the harbor and beaches, and 

 that further general studies should be made of this type of operation; 



Be The beaches east of the harbor are now being maintained 

 in a delicately balanced state of equilibrium, which should not be 

 disturbed in attempting to improve them by building additional struc- 

 tures or by removing any existing structures » 



He recommended continuation of the adopted plan of artificial beach 

 nourishment in connection with harbor maintenance, no additions or 

 other changes in existing protective structures on the beaches, and 

 that this cooperative study be considered complete with the publica- 

 tion of this reporto 



The Division Engineer concurred gaierally in the views and re- 

 commendations of the District Bigineero He believed that the present 

 maintenance procedure should be continued until plans under con- 

 sideration for further development of the harbor are definitely es- 

 tablished and that the existing project for maintenance of the harbor 

 should not be modified at this timeo 



The Board carefully considered the reports of the reporting 

 officers o It concurred in general in their views and recommendations. 

 It noted that although the adopted program has restored the beaches 

 to a condition approaching stability, the present alignment of the 

 beaches is, in some places, considerably shoreward of its 1929 

 position. This is hardly surprising in view of the complete inter- 

 ruption of material supply for the 10-year period prior to 1938 o 

 Recent operations have constituted a resumption of normal sustaining 

 supply, but have not made up for the years of no supply. The material 

 which would normally have reached the beach during that period still 

 lies behind the breakwater and in the offshore mound east of the 

 harbor. The Board's report recommending the adopted program pointed
