<br />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 ([-lock and <br />Bray, 1977) a~td appears applicable to the constructed grading. <br />The stability of slopes can be impacted by poor surface drainage and inadequate <br />revegctation. We assume that the drainage and revege[ation conditions have been <br />addressed by others. <br />Tltis evaluation Itas been conducted according to generally accepted gcoleclmical <br />engineering principles and practices in this area at this time. The conclusions are based on <br />the information provided, our cursory review of the site and experience in the area. <br />Subsurface exploration and testing and measurements of the constructed embankments <br />have not been performed. Vaziations iu 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 />Sincerely, <br />HEPWORTH-PAWLAK GEOTECI~I] <br />1 ~~~,~`yaS e,ee;i/~ `h <br />y ~ / •.~ <br />~.. <br />Steven L.
