PROJECT DESCRIPTION <br />Background <br />The purpose of this application is to obtain authorization for Hall-Irwin Construction 'Company (Hall- <br />Irwin) to mine, process and sell sand and gravel, sell landscape materials, and operate concrete, <br />recycling and asphalt batch plants at the Water Resources, LLC property. Hall-Irwin will mine <br />approximately 89 acres of the total 134.21-acre property. Upon completion of ~Ithe mining and <br />reclamation, the site will be used for water storage. Please see the attached map i for the specific <br />location of the azea to be mined. <br />Existing Conditions <br />This site is irrigated agricultural land, presently used to produce corn and oats. Topography of the <br />area to be mined is generally flat, sloping slightly to the east. <br />There is a significant commercial deposit of sand and gravel located in the alluvium of the South <br />Platte River on this property. The South Platte River lies just to the north and west of the site. <br />Portions of the site may flood during periods of high runoff as portions of the area to be mined are in <br />the 100-year floodplain (see Mining Plan Map for location of floodplain). Development of the <br />mining and reclamation plan incorporated measures to mitigate the impact of the operation on <br />floodwater. Hall-Irwin has completed a Floodplain Development Permit for this operation. In <br />addition, the Plumb Ditch borders the site to the south. i <br />Surrounding land uses include residential and agricultural. There aze no existing buildings on the <br />parcel, however there aze several oil and gas wells, tanks and appurtenances that will'not be impacted <br />by the mining operation. A stability analysis was conducted and used in the development of the <br />mining plan. Hall-Irwin is in the process of obtaining development agreements with the oil and gas <br />companies. <br />Hall-Irwin Corporation ~ Page 1 of 35 <br />MLRB 112 Permit Application i <br />
