40 <br />KELLER, SCHLEICHER & Mac WILLIAM ENGINEERING AND TESTING, INC. <br />P.O. BOX 78-1377, SEBASTIAN, FL 32978-1377 SEBASTIAN (561) 589-0712 <br />MELBOURNE (407) 768.8488 <br />FAX(561)589-6469 <br />Shooting <br />Range <br />-2- <br />June 16, 1998 <br />C. The <br />scope of our <br />study consisted of <br />the following:. <br />1. Performed two (2) constant head permeability tests in <br />the field along with a 7' deep test boring at each <br />location. Also, obtained a Shelby tube soil sample and <br />performed a constant head horizontal permeability test in <br />our laboratory on the samples for each boring location. <br />Calculated the permeability coefficient 'K' value and <br />also estimated the normal wet -season water table and <br />projected wet season water table at each location. <br />2. Performed sixteen (16) soil borings in the locations <br />given to K.S.M. by your office, fourteen (14) to a depth <br />of ten (10) feet and two (2) to a depth of twenty (20) <br />feet to evaluate the soil suitability for on-site fill. <br />A. Engineering Evaluation: <br />Based on the information obtained from this site investigation we <br />are pleased to offer the following evaluation: <br />1. Groundwater 6 Soil Permeability: <br />The cRisting yLaus,dwaLer table was measured in the test holes at <br />depths of 38" to 40" below existing grade. This water table will <br />rise throughout the year, primarily due to seasonal variation in <br />rainfall. <br />Yearly rainfall is generally from 50 to 55 inches, with almost two- <br />thirds of this value occurring during the summer and early fall. <br />September generally has the most rainfall followed by June, October <br />and August. The period of least rainfall occurs from November to <br />April. <br />W <br />W <br />
