The District and Division Engineers and the Beach Erosion Board con- 

 cluded that the modified plan of shore protection for Oceanside should 

 provide a protective beach 200 feet wide for about 13,000 feet between 

 Camp Pendleton Harbor and Witherby Street and 100 feet wide for about 4,500 

 feet south of Loma Alta Creek by artificial placement of approximately 

 2,200,000 cubic yards of suitable sand, including 500,000 cubic yards of 

 sand as advance nourishment, and a groin about 800 feet long near the north 

 limit of the fill to prevent future loss by impoundment within the harbor 

 area. Periodic nourishment of the beach fill would be accomplished by 

 artificial placement of sand in connection with maintenance dredging of the 

 navigation channels at Camp Pendleton Harbor and the proposed civilian 

 small-craft harbor, at no cost to the project. They made an economic 

 analysis of the modified plan for Oceanside and concluded that the modified 

 plan is justified by prospective benefits, that the erosion has been caused 

 by construction of Camp Pendleton Harbor by the United States as a wartime 

 measure, without provisions for preventing damage to adjoining shores, and 

 that in equity the restoration of beach conditions existing prior to harbor 

 construction should be a Federal responsibility. They accordingly recom- 

 mended adoption of a project in lieu of the authorized project at Oceanside 

 to provide a protective beach generally 200 feet wide by 13,000 feet long 

 north of Witherby Street and generally 100 feet wide by 4,500 feet long 

 south of Loma Alta Creek, and to provide a stone groin about 800 feet long 

 near the north limit of the fill. They also recommended, subject to certain 

 conditions, that the total first cost of the work be borne by the United 

 States, but that the cost of maintaining the groin be borne by local interests. 



The Chief of Engineers concurred in the views and recommendations of the 

 Beach Erosion Board and further recommended that any material dredged in con- 

 nection with Camp Pendleton Harbor or any subsequently developed civilian 

 harbor in the area be used for nourishment of the Oceanside beach, and subject 

 further to the condition that local interests agree that the cost allocated 

 to this beach protection project shall be adjusted to reflect the savings from 

 multiple-purpose construction of the addition of the contemplated Oceanside 

 harbor improvement to the over-all project, if authorized, and the cost so 

 transferred from the Beach erosion project to the harbor project be shared 

 by local interests and the Federal Government as appropriate for small-boat 

 harbor projects. 



AMELIA ISLAND (FERNANDINA BEACH), FLORIDA 



The purpose of the investigation was to determine the most satisfactory 

 method of restoring and preserving the beach for protection of existing 

 structures and for recreational use. Amelia Island is in Nassau County in 

 the northeast corner of Florida, about 20 miles north of Jacksonville. The 

 island is about 13 miles long between St. Marys River on the north and Nassau 

 Sound on the south. The City of Fernandina Beach is near the north end of 

 Amelia Island. The 1950 populations of Fernandina Beach and Nassau County 

 were respectively about 4,400 and 12,800. Although summer increases in 

 population have been small, the trend is toward more summer resort activity
