Additional short-term changes that primarily affect the upper sections of 

 the profiles result from the periodic removal of sand from under the Boardwalk 

 (see Figs. 40, 41, and 42) for use as fill elsewhere on the beach (see Fig. 

 43). Although this procedure has been observed, it is not well documented in 

 terms of frequency or quantities of material transferred. The project during 

 the winter and spring of 1979 was done by the City and called for the removal 

 of 36,600 cubic meters of sand from under the Boardwalk near profile line 7 

 (Richmond to Raleigh Avenues) (M. Ingram, City Engineer, personal communica- 

 tion, March 1979). This material was then placed on the foreshore midway 

 between profile lines 4 and 5. Because of the relatively fine size of this 

 well-sorted sand (0.18 millimeter compared with 0.27 millimeter reported by 

 Ramsey and Galvin, 1977, for average foreshore sand size in March), the mate- 

 rial would probably be easily eroded from the beach face.
