borings drilled at the site, the property contains approximately four <br />million (4,000,000) cubic yards of sand and gravel. Approxirnately two <br />hundred seventy thousand (270,000) cubic yards of overburden will have to <br />be removed to obtain the sand and gravel. The majority of the gravel en- <br />countered is below groundwater. The area being quarried will have to be <br />dewatered or the gravel will have to be excavated by use of a dragline <br />and /or dredge. Based on a visual inspection of the sand and gravel in <br />the test borings, it is our opinion that material is good quality <br />aggregate. The majority of the aggregate appears to have a maximum size_ <br />of one and one -half (1 -1/2) inch with only minor amounts of cobbles <br />ranging in size to four (4) to six (6) inches. It is felt that this <br />material would be suitable for use as pit -run gravel and /or structural <br />fill and with extensive screening may be used in concrete or asphaltic <br />concrete or as a base course material or for other construction uses. <br />However, additional expense may be required to meet these more rigid <br />specifications due to the lack of coarse material in the granular layer. <br />GENERAL C(NIMENTS <br />Variations in soil and groundwater conditions may exist between <br />test borings. These variations may not become evident until quarrying <br />operations take place. It should be noted that the quantities presented <br />in this report are based on an average thickness of overburden and sand <br />and gravel interpolated between test borings at the site. Additional <br />test borings, test pits. and laboratory analysis may be required prior <br />to any proposed quarrying operations to more accurately determine the <br />quantity and quality of the granular materials encountered at the site. <br />-4- <br />M <br />
