This work is being perfcmned <br />as authorized by you on September 8, 1994. Our authorized scope of work includes the <br />following: <br />• One standard penetration test boring, which was ext»ided to a depth of 36'. <br />• Water content testing in the laboratory. <br />• Geotechnical engineering review of the effects of a 2' grade raise, and preparation of this <br />report. <br />#Il*J L-vH MfflDBMltfQB <br />A segment of Kelly Avenue west of Lydiard Avenue extends through a low swanq>y area. <br />Because the road has settled with time, the lower surface elevation of the road results in periodic <br />flooding. Therefore, you plan to study the effects of adding 2' of fill to the currait road <br />embankment to reduce the potential for flooding. We undentand watermain and sanitary sewer <br />utilities lie below the existing street It is believed the watermain is supported by the existing <br />road embankment, although the sanitary sewer has more recendy been reconstructed and is <br />reportedly supported on piling. <br />Subsurface Exploration <br />The subsurface exploration program consisted of one standard penetration test boring on <br />September 16, 1994. Originally, we had planned a boring depth on the order of 20', although <br />because of conditions, the boring was extended to 36' to penetrate organic and very loose soils. <br />• AN AFFIRMATIVE ACTION EMPLOYER ' <br />2102 Unlnnlty Avt.
