4.3.1. Shoreline Change 



Calculation procedures adopted to establish the magnitude of change in shoreline position 

 and sand volume for the Applegate property were applied in quantifying change at the Noro 

 property. The two beach-profile surveys bracketing the purchase date at Monuments R-43 and 

 R-44 are August 28, 1985, and December 1, 1993. After establishing the MHWL (2.06 ft 

 NGVD) associated with R-43 and R-44 (based on tidal datums for that locale), change in 

 shoreline position was calculated at each line. At both R-43 and R-44, the MHWL on 

 September 11, 1996, receded approximately 9 ft since the time of purchase (September 8, 1986). 

 Therefore, the MHWL at the Noro property (which lies between the two monuments) also 

 receded 9 ft during the time of ownership. Given previously discussed uncertainties in estimating 

 shoreline position through interpolation between different seasons, a 9-ft change in shoreline 

 position over a ten-year period cannot be considered a trend (does not signify a change). 



4.3.2. Volume Change 



Configurations of beach profiles at R-43 and R-44 were established for the period of 

 ownership by interpolation between profiles bracketing September 8, 1986, and September 11, 

 1996. Changes in sand volume are 1.4 and 0.0 cy/ft net erosion at R-43 and R-44, respectively 

 (See Figure 4-10 and Figure 4-11). These values produce an average loss in sand-volume per
