<br />• <br />Visual examination of the ground surface between monuments "F" <br />through "I" indicates no surface tension or compression features. <br />Thompson Ranch Structures <br />Survey data pertaining to the Thompson Ranch Structures for the <br />period of record are shown on Table 3, Subsidence Monitoring Data <br />Summary. No measurable subsidence occurred at the structure <br />monitoring points, consistent with previous subsidence monitoring <br />data. Only minor additional subsidence is anticipated to occur <br />at the ranch structures. <br />Newlin Creek Monument <br />Survey monitoring data for the Newlin Creek Monument are present- <br />ed on Table 3, Subsidence Monitoring Data Summary. No measurable <br />subsidence occurred at the monument for period of record of this <br />report. Total cumulative subsidence is shown as 0.60 feet to the <br />end of the semi-annual monitoring period. Only minor additional <br />subsidence is anticipated to occur at the streambed monument. <br />Conclusions <br />• Southfield's required subsidence monitoring program continues to <br />measure displacement and orientation changes of structures and <br />monuments. To date, no damage has been observed at the monitored <br />structures that may result from subsidence. It is anticipated <br />that only minor additional subsidence will occur at the monitored <br />locations, and the magnitude of subsidence will be within values <br />predicted in the permit application. <br />.e <br />r1 <br />LJ <br />
