Little Harbor Breakwaters 



Little Harbor, N.H. 



Date(s) Construction and Rehabilitation History 



1894- Two rubble-mound breakwaters were constructed to lengths of 550 and 

 1903 900 ft on the north and south sides of the entrance to Little Harbor 

 (Figure 16). 



1905 Minor repairs were made using 476 tons of stone. 



1959- Based on several visual inspections, the jetties were considered to 



1974 be in poor condition. 



1975 Seaward sections of the north and south jetties, 350 and 850 ft long, 

 respectively, were repaired using 4 to 7-ton stone. The design cross 

 section (Figure 16, inset) had a +12 ft mlw crown elevation, a 12- or 

 14-ft top width, and 1V:1.5H side slopes. The side slope on the sea- 

 ward facing quadrant of the breakwater heads was 1V:2H. The cost for 

 placing 7,800 tons of stone was $159,500. 



1983 An inspection showed that the north jetty had a few small areas of 



displaced stone, and the south jetty had substantial damage which was 

 subsequently repaired along the seawardmost 150 ft. 



1985 Visual inspection indicated the breakwaters were in good condition.
