subsequent periodic nourishment thereof including operation of the sand- 

 transfer plant at South Lake Worth Inlet 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 Engineer, with such modifications 

 thereof as may be considered advisable by the Chief of Engineers. Federal 

 assistance would entail contribution of funds toward the initial construc- 

 tion costs of the beach restoration and of the costs of periodic nourish- 

 ment for a period of 10 years in amount of 3.2 percent for the Martin 

 County- Jupiter Inlet segment, 7.7 percent for the Jupiter Inlet-Lake Worth 

 Inlet segment and 3.4 percent for the South Lake Worth Inlet-Boca Raton 

 Inlet segment. 



The Chief of Engineers concurred in the views and recommendations of 

 the Beach Erosion Board. 



DELAWARE BAY COAST OF NEW JERSEY 



(Cape May Canal to Maurice River) 



The purpose of the investigation was to develop the most suitable plans 

 for restoration and protection of the problem areas. The study area is in 

 Cape May and Cumberland Counties, New Jersey. It comprises the Delaware Bay 

 shore from the entrance of Cape May Canal to the mouth of Maurice River, a 

 shore length of about 22 miles centered about 70 miles southeast of Phila- 

 delphia, Pennsylvania. A narrow strip of the coast, principally between 

 Cape May Canal and Bidwell Ditch, is developed to a minor extent as a summer 

 resort area. The estimated permanent population of the shore communities is 

 about 3,200 and the summer population is about 23,300. About 10 percent of 

 the shore frontage is publicly owned, but it is not developed for public use. 

 The shore from Bidwell Ditch to Cape May Canal, approximately 11 miles long, 

 is oriented north to south. It is characterized generally by low banks, 

 narrow beaches and offshore mud flats. Accretion of sand has occurred north 

 of the Cape May Canal and south of the Bidwell Ditch jetties at the ends of 

 this section. North of Bidwell Ditch to West Creek, a distance of 4 miles, 

 the shore is concave. It is undeveloped and fronts marsh land. Wes t of 

 West Creek, a frontage of about 7 miles to and including East Point, the 

 shore is oriented generally from east to west. It consists generally of 

 sandy beaches with scattered houses fronting marsh land. Tides in Delaware 

 Bay are semi-diurnal, their mean range being 4.7 feet at Cape May Point and 

 5.7 feet at East Point near the mouth of Maurice River. The maximum tide 

 of recent record was about 10 feet above mean low water at East Point. 

 Storms in Delaware Bay are the sole cause of important wave action. Accretion 

 at the Cape May Canal north jetty and the Bidwell Ditch south jetty indicates 

 littoral transport in both directions along that section of shore, with pos- 

 sibly some northward predominance. From East Point to Dennis Creek, the 

 littoral transport probably has a slight eastward predominance. Rates of 

 movement and loss are apparently low. 



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

 cluded that the most suitable plans of protection for the several problem
