• NCIG Financial, Inc. <br />December 2, 1994 <br />Page 2 <br />overall failure is greater than 1.3. The analysis is based on chart solutions (Hoek and <br />Bray, 1977) and appeazs applicable to the constructed grading. <br />The stability of slopes can be impacted by poor surface drainage and inadequate <br />revegetation. We assume that the drainage and revegetation conditions have been <br />addressed by others. <br />This evaluation has been conducted according to generally accepted geotechnical <br />engineering principles and practices in [his azea at this time. The conclusions aze based on <br />the information provided, our cursory review of the site and experience in the azea. <br />Subsurface exploration and testing and measurements of the constructed embankments <br />have no[ been performed. Variations in the assumed slope conditions could change the <br />conclusions made in this report. <br />If you have any questions or if we can be of further assistance, please let us know. <br />• <br />Sincerely, <br />HEPWORTH-PAWLAK GEOTECHNI <br />,.~. <br />p <br />t<,.~ ~v~~s e9co-vf <br />e <br />S~ji"~, 15222 0 <br />Steven L.
