PART II: FIELD EXPERIENCE 

 Summary of Contacts and Visitations 



4. During the period February 1984 to October 1985, 9 division and 

 21 district offices (Table 1) of the Corps were contacted by telephone in 

 order to determine whether any rubble-mound toe stability problems presently 

 exist or have existed on the coastal structures under the jurisdiction of the 

 various offices. The points of contact at each district office were those 

 recommended by the REM Field Review Group members from the district's 

 division office. Of the 21 districts contacted, 12 responded positively 

 regarding existing or past toe stability problems. 



5. Prior to a district office visit, a copy of the district's project 

 index maps was obtained in order to become familiar with the authorized 

 coastal structures and their current status. During the planning stages for a 

 district visit, it was requested through the district point of contact that 

 upon arrival at the district office a meeting be held so that a detailed 

 explanation of the purposes of the visit could be given and so that an over- 

 view of the district's coastal structures and the various problems and repair 

 histories related to them could be obtained. Notably, the Wave Research 

 Branch (WRB) of CERC is funded for three REMR work units other than the one 

 being addressed herein, namely, (a) "Use of Dissimilar Armor for Repair and 

 Rehabilitation of Rubble-Mound Structures," (b) "Repair of Localized Damage to 

 Rubble-Mound Structures," and (c) "Techniques of Reducing Wave Runup and Over- 

 topping on Coastal Structures." In addition to these, the WRB has been autho- 

 rized under the Coastal Program's Research and Development Work Unit titled 

 "Breakwater Stability" to write case histories on all breakwaters and jetties 

 built and/or maintained by the Corps of Engineers. All of these work units 

 require the gathering of field data; and for this reason when WRB personnel 

 visited a district office, data were gathered, when available, for each of the 

 work units. It was requested that, where possible, the meeting be attended by 

 district representatives from planning, design, engineering, construction, and 

 operations. In this way, it was assumed that the data obtained would reflect 

 all areas of concern relative to a district's coastal structures.
