., <br />• Drainaee; The collection and diversion of surface drainage away from the roadway area is extremely <br />important for satisfactory performance of the roadway. The design of surface drainage features should <br />be carefully considered to remove all water from all roadway azeas. In addition, the maintenance of all <br />drainage structures should be conducted periodically to ensure proper performance. We recommend <br />that the new gravel surface be constructed with a crown or super elevation of a[ least 2 percent. <br />Limitations: This report has been prepared in accordance with generally accepted soil and pavement <br />engineering practices in [his area for use by the client for desigo purposes. The conclusions and <br />recommendations submitted in [his report are based upon the assumed traffic loadings and the data <br />obtained from the test holes advanced along the subject roadway. If during construction, soil and <br />ground water conditions appear to be different from those described herein, this office should be <br />advised at once so [h [ r evaluation of the recommendations may be made. We recommend the on- <br />site observation o ~ :nt and compaction by a qualified soils <br />engineer. <br />Sincerely, <br />Brian D. Len, P.E. <br />• <br />• <br />--~ 1~ <br />
