of the remaining first costs of the three projects. In addition Federal 

 aid of one-third of the costs of periodic nourishment for an initial period 

 of ten years from the year of completion of the initial work was recommended 

 for Town Neck Beach. 



The Chief of Engineers concurred in the views and recommendations of 

 the Beach Erosion Board. 



SOUTH SHORE OF LONG ISLAND FROM FIRE ISLAND INLET TO MONTAUK POINT, NEW YORK 



The purpose of the investigation was to determine the most practicable 

 and economical method of restoring adequate recreational and protective 

 beaches and providing continued stability to the shore. In addition to a 

 single-purpose shore protection plan developed under the foregoing authority, 

 the report submitted by the District and Division Engineers included study of 

 the needs and methods for protection against damages caused by hurricanes 

 under the provisions of Public Law 71, 8Uth Congress, resulting in a dual- 

 purpose plan which would provide both hurricane and shore protection. In 

 its review of the report the Beach Erosion Board gave consideration to the 

 technical adequacy of both plans but limited its consideration of project 

 justification and Federal participation to the single-purpose shore protection 

 plan in accordance with its statutory functions as prescribed in section 

 3 of Public Law 166, 79th Congress. 



The study area, lying entirely in Suffolk County, comprised the 

 83-mile length of shore on the south coast of Long Island between Fire 

 Island Inlet and Montauk Point. The western end of that area is about 

 50 miles by water south and east of New York City. This shore is an 

 important summer recreational area with development ranging from colonies 

 of small bungalows to villages of large summer homes. Suffolk County had 

 a permanent population of over 528,000, with over 368,000 living in towns 

 adjacent to the study area, according to 19!?7 estimates. The summer 

 population is increased by thousands of vacationists. At the time of 

 reporting about 18. h percent of the shore in the study area was publicly 

 owned. The principal publicly owned sections were Fire Island and Hither 

 Hills State Parks, and Smith Point Park owned by Suffolk County. Additional 

 shore areas on each side of Moriches and Shinnecock Inlets are being 

 acquired by Suffolk County for park purposes but were not included as 

 publicly owned shore in the present report for computations of the extent 

 of Federal assistance in proposed protective measures. The coastal area 

 under study is divided into two distinct natural sections. The westerly 

 5>0-mile section consists of barrier beach islands generally less than 

 1/2 mile in width. The easterly 33-mile section of the shore consists of 

 the mainland of Long Island, the 10-mile reach west from Montauk Point 

 being characterized by headlands of glacial deposits. The shore of the 

 study area is exposed to waves of the Atlantic Ocean. To the east and 

 southeast the fetch is unlimited, but to the west and southwest the fetch 

 is limited by the shore of New Jersey. The predominance of energy 

 components is thus such as to produce a dominant westward littoral 

 transport of beach material. The estimated annual rate of littoral transport 

 at Fire Island Inlet is Uf>0,000 cubic yards. The importance of reversals
