Remediation work began in late September, 1995 and was completed with <br />the installation of diversion ditches on October 27, 1995. The following remediation steps were <br />accomplished: <br />- Topsoil was stripped and salvaged from the remediation disturbance area. <br />- The berm was removed at the norther tce of the slide. <br />- French drains were installed in the manner and at the locations described in TR-69. <br />- The azea was recontoured as described in TR-69. <br />- The azea disturbed was retopsoiled and seeded with the appropriate seed mixture. <br />- Diversion ditches were installed as described in TR-69. <br />Monitoring of the landslide area was initiated on October 30, 1995 with groundwater levels, flow from the <br />French drain, slide stability, and required flow capacity of diversion ditches all examined. Thus far, the <br />French drain is flowing at approximately .75 GPM and installed piezometers show standing groundwater <br />still existing. The shde area and diversion ditches are stable. <br />Please contact me should you have any questions or concerns. <br />FVUjsb <br />[95-NOVOIJ <br />c File 109.2.4 <br />7Rfi9 Filc <br />Jim Pendleton, CDMG <br />Ric Fmyo, Dufford & Brown <br />P.0.
