project under which the United States would pay 59.7 percent of the first 

 costs thereof and 11.6 percent of the annual costs for periodic nourishment 

 for a period of 10 years. 



The Beach Erosion Board concurred generally in the features of both 

 the single-purpose and dual-purpose plans of protection for the shores of 

 Carolina Beach and vicinity. The Board concluded that while it would be 

 possible to provide effective erosion control independently of hurricane 

 protection, provision of the latter by means of constructing and maintain- 

 ing a berm and dune of adequate height and width necessitates effective 

 supplemental measures for beach erosion control. It was the opinion of the 

 Board that the dual-purpose plan is a technically practicable partial pro- 

 tection plan for the Carolina Beach and adjacent areas. Although it would 

 provide reasonable protection under design storm conditions as contemplated 

 by the reporting officers, it would provide little protection under condi- 

 tions of the maximum hurricane that could reasonably be expected to occur 

 in this area. The Board therefore considered that an adequate warning 

 system, as well as plans and routes for rapid evacuation of the coastal 

 region, would be essential supplements to the plan of protection recommended 

 by the District and Division Engineers in order to prevent loss of life. 

 Regarding the dual-purpose plan, the Board also pointed out that the berm 

 elevation of 12 feet above mean low water is higher than the natural berms 

 formed by wave action in this area, and that part of this high berm may be 

 removed during storm profile adjustments. Such berm restoration as would 

 occur during subsequent wave action would no doubt be at the lower natural 

 level associated with the wave and tidal characteristics of the region. 

 As the effectiveness of the hurricane protection is dependent on the high 

 berm, the Board emphasized the importance of the program to reform the high 

 berm annually before the hurricane season, as contemplated in the District 

 Engineer's plan. Accordingly, subject to determination by the Chief of 

 Engineers after review by the Board of Engineers for Rivers and Harbors 

 that the dual-purpose plan for the entire area is suitable and economically 

 justified, the Beach Erosion Board recommended adoption of a project for 

 about 25,800 feet of the shores of Carolina Beach and vicinity to authorize 

 Federal participation in the costs of a plan for protection of the shores 

 from hurricane and erosion damage comprising for the latter feature alone 

 artificail placement of fill to provide a beach berm 100 feet wide at an 

 elevation of 8 feet above mean low water, a feeder beach, and periodic 

 nourishment of the beach, the Federal aid for the latter to apply for a 

 period of 10 years from the year of completion of the initial placement, 

 substantially in accordance with the plan developed by the District and 

 Division Engineers, with such modifications thereof as in the discretion 

 of the Chief of Engineers may be advisable. The Board of Engineers for 

 Rivers and Harbors and the Chief of Engineers concurred in the conclusions 

 and recommendations of the Beach Erosion Board.
