The surveys were performed September <br />25, and November 10, 1993. <br />The slope failures that occurred this spring have been repaired. <br />The survey results indicate that the bench continues to be <br />structurally stable overall. The surveys also show that very <br />little movement has occurred since the monuments were installed in <br />1985 and since the last survey was performed on July 3, 1993. No <br />Division concerns have resulted from review of this data. <br />Please let me know if you have any questions. <br />'ly <br /> <br />Christine E. Jo s on <br />Environmental rot ction Specialist <br />cc: David Berry, DMG <br />BENMON <br />
