The average overburden thickness is nine and one-half <br />' (9-1/2) feet along the northern edge of the site and five (5) feet over <br /> the majority of the property. Based on the test borings drilled at the <br /> site, The property contains approximately four million three hundred and <br /> fifty thousand (4,350,000) cubic yards of gravel. Two million cubic <br />' yards of overburden will have to be removed to obtain the sand and <br /> gravel. This gives a ratio of gravel to overburden of approximately <br /> 2.2:1. Since the majority of the sand and gravel encountered is below <br />ill h <br />th <br />h <br />i <br />i <br />d <br /> or <br />e <br />ground water, t <br />e area be <br />ng quarr <br />ed w <br />ave to be dewatere <br /> gravel will have to be excavated by use of drag line. <br />' Based on a visual inspection of the sand, gravel and cobbles <br /> encountered in the test borings, it is our opinion that this material is <br />' good quality aggregate suitable for use in and as construction materials. <br />GENERAL COMMENTS <br />' Variations in soil <br />test b <br />i <br />Th and groundwater conditions may exist between <br />i <br />til <br />i <br />ti <br />t b <br />id <br />t <br /> or <br />ngs. <br />ese va a <br />ons may no <br />r <br />ecome ev <br />en <br />un quarry <br />ng <br /> operations take place. It should be noted that the quantities presented <br />t 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 needed prior to <br /> proposed quarryin g operations to more accurately evaluate the quantity <br /> and quality of the granular materials encountered at the site. <br /> <br />1 <br />1 , <br /> <br /> <br />• -4- <br />
