Following <br />completion of the project, our staff completed a field inspection of the project area during the summer of 2013 to <br />verify that no corrective or stabilization efforts were needed. The limited brushing required resulted in very <br />localized soil disturbance, but no appreciable soil loss or erosion, so no corrective or stabilization work was <br />necessary. A follow -up inspection in early- summer 2014 confirmed that there was no remaining visible indication <br />of disturbance from the 2012 seismic activities, so we consider this project closed -out and completed, with no <br />further reclamation or management necessary — <br />Best regards, <br />Jerry <br />Jerry M.
