littoral movement was then southward. Local interests again raised 

 money to dredge the impounding area. Between January l5-2lj, 1953 a 

 12-inch pipe line dredge removed about 1*0,000 cubic yards of sand 

 from the impounding area and discharged it on the south shore. The 

 impounding area was dredged to about 20 feet below mean low water. 

 When the work was completed the inlet mouth was wide, had scoured to 

 rock and was in excellent condition for navigation. 



By the fall of 195U the impounding area had about filled to 

 capacity and the shore south of the inlet needed nourishment. In 

 January 195$, 60,000 cubic yards were dredged from the impounding 

 area and placed on the south shore. Experience to date indicates 

 that for best results for both navigation and beach r estoration, 

 maintenance dredging in amount of about 75 * 000 cubic yards should be 

 performed during the fall of each year. 



Concluding Remarks 



Consideration is now being given to a permanent pumping in- 

 stallation with special features but of simple design, mounted on a 

 barge, for regular maintenance at this inlet. A single fixed spud 

 mooring will be left in place at the settling basin, from which the 

 pump barge will operate. When not in use, and especially during 

 adverse weather, the pump barge will be berthed elsewhere for safety. 



It is believed that for better beach protection the south jetty 

 built by local interests, should be extended to the original re- 

 commended length of 700 feet. It was shortened to U50 feet in order 

 to obtain steel piling to reinforce its present seaward end. 



This plan appears to offer control of the inlet from a navigation 

 standpoint and to provide sand nourishment to the shore south of the 

 inlet, both features being accomplished at an annual cost within the 

 means of local interests. The success of this plan at Hillsboro 

 Inlet suggests that similar approaches, with sand "spillways" con- 

 structed on a wholly artificial basis, might be considered at other 

 inlets.
