Colonial Beach, Virginia 



Baltimore District 



Date(s) Construction and Rehabilitation History 



1982 Seven offshore breakwaters were constructed as part of a beach 



restoration project for approximately $447,000, using over 9,000 tons 

 of stone (Figure 63). One 300-ft breakwater and two 200-ft break- 

 waters were placed at Castlewood Beach, and four 200-ft breakwaters 

 were placed at Central Beach. All were placed parallel to the shore- 

 line and approximately 100 ft offshore, and they were separated by 

 150-ft gaps. Crest elevations were +3.0 ft mlw but allowed for set- 

 tlement to +2.0 ft mlw. Crown widths were 6.0 ft, and side slopes 

 were 1V:1.5H. One layer of 2,000-lb cover stone was placed over one 

 layer of 500-lb underlayer resting on a core and 1 ft bedding layer. 

 Design wave height was 6.0 ft. 



1985 The breakwaters are in excellent condition and serving their intended 

 function.
