<br /> <br />Topograpi~y and Drainage <br />The study area is in the floodpluin of the South Platte <br />River. Elevations range from 5077 feet at the southo-aest corner <br />to 499II feet in the northeast adjacent to the river, Total <br />relief in the area studied east of the 6rantner Ditch is about <br />20'. <br />There are no well defined dr-ainayeways eastward from the <br />Brantner Ditch to the river. ~latural slope toerard the river <br />would carry excess surface water; however, an artificial levee <br />would preveirt surface runoff from taking its natural course to <br />the river. Excess 'water trauped by file levee either evaporates <br />or passes dorm card to the ground era ter table. <br />Methods and Procedures <br />Data gathered from well logs obtained from the State Engi- <br />neer's Office was used to co~npile depth-to-bedrock and over- <br />burden t;rickness maps. The available information eras not suffi- <br />cient to determine the quantity and quality of aggregate under- <br />lying the property, and an exploratory dri]ling project .vas re- <br />commended and approved. Becker Drills, Inc, was contracted to <br />drill a series of test holes in the period January 12-16, 1974. <br />Laboratory analysis of san;ples recovered in the drillino prooram <br />was made by Robert 1•!. Thompson, Inc., and our personnel visually <br />examined the samples for deleteriuus material. A series of six <br />erork maps was prepared and volumetric calculations were made from <br />these. Final maps accnrnpanyinq this report are: <br />7356a-1 Depth to Bedrock <br />7356a-2 Thickness of IiA <br />~25Z~ <br />I - 2 <br />
