DRAFT FOR REVIEW <br />KLElNFELt~ER <br />January 22, 2008 {Revised January 30, 2008) <br />File No. 06501 PROP <br />LJ Development, tnc. <br />256 North Merrill Drive <br />Pueblo West, Colorado 8'1007 <br />Attn: Mr. Joe Gagliano <br />Subject: Draft Proposal <br />Rocky Ford High line Cana! Stability and Seepage Evaluation <br />Pheasant Run Gravel Pit <br />Nepasta Road and US Highway 5Q East <br />Pueblo County, Colorado <br />Dear Mr. Gagliano: <br />As requested, we are providing this proposal to perform an embankment stability and <br />seepage evaluation of the Rocky Ford Highline Canal in regards to potential impacts of <br />proposed mining of the Pheasant Run Gravel Pit to the northern and southern sides of the <br />existing canal. Our original proposal dated January 22, 2008 was revised based on our <br />recent telephone conversations with you. This proposal is based on our site visit, telephone <br />conversations with you, and various maps provided to us induding: <br />• Exhibit Index Map {August 6, 2007) <br />• Exhibit "C" Mining Planning {January 12, 2008) <br />• Exhibit "F° Reclamation Plan Map (January 11, 2008) <br />We understand that the mining operations will occur in three phases, spanning a total of 15 <br />years and approximately 5,000 linear feet along the High Line Canal (indusive of bath <br />sides}. The expected canal no mining "easement" is approximately 50 feet from the ditch <br />banks, symmetrical to the north and south sides. Permanent cut slopes are expected to <br />begin at the edge of the "easement' and slope at approximately 3 (horizontal) to 1 {vertical} <br />for cuts up to about 20 feet below the bottom of the existing canal. <br />PURPOSE <br />Based on our current understanding of the project, the purpose of our services will be ta: <br />• Obtain subsurface soil data and measure existing groundwater depths. We will also <br />provide means for continued groundwater depth monitoring by installing piezometer <br />casings at all borehole locations. <br />• Perform a preliminary evaluation of seepage of the canal for the proposed <br />embankment configurations for use in excavation considerations and global stability <br />analysis. <br />06501 PROP/CSP8P035 <br />Copyright 20pg Kleinfelder <br />Page 1 of 5 <br />January 30, 2008 <br />KLEINFELDER 4815 List Drive, Unit 115, Colorado Springs, CO 80919 (719) 632-3593 (7191 63?-?648 fax <br />
