INTRODUCTION <br />This report presents the Puckett Land Company's Nolte Pit #1 erosion control report. The <br />design and analysis of this site has been performed in accordance with the County of Garfield <br />County Engineer Specifications, latest edition and Urban Drainage and Flood Control District, <br />Urban Storm Drainage Criteria Manual, Volumes 1, 2, & 3, June 2001. Drawings, tables, and <br />design calculations are included in the appendix of this report. <br />Site Location <br />The site is located in Southeast Quarter of Section 19, Township 7 South, Range 96 West of the <br />6 Principal Meridian, County of Garfield, State of Colorado. <br />The site is bounded to the north by a Colorado Department of Transportation (C -DOT) Office <br />and yard; to the west and south by Bureau of Land Management (BLM) property; and to the <br />east by Colorado Department of Transportation's frontage road and Interstate -70. <br />Site Description <br />The site is approximately 22.34 acres in size. The site consists of an existing well pad and <br />native landscaping. The topography for the site generally slopes southeasterly at slopes ranging <br />from 2.0% to 37 %. The soils within the site are clay barns; rock outcrops and fall into Hydrologic <br />soils group Type D. The landscaping on site is native. <br />Proposed Project Description <br />The proposed grading operations are being planned in order to provide earthwork for an <br />adjacent transportation project. A site access drive cut and a temporary gravel haul road will be <br />constructed. <br />EROSION AND SEDIMENT CONTROL PLAN <br />Volumes and Areas Impacted <br />The affected boundary area represents 13.96 acres. The grading operations for this project will <br />disturb approximately 9.86 acres. Cuts and fills ranging from -38 to +2 feet are expected during <br />grading operations. The final grading is expecting to see a net cut of 100,000 cubic yards. These <br />quantities are approximate and do not include over - excavation or shrink/swell factors. The <br />contractor is responsible for performing their own calculations for the earthwork. The Contractor is <br />responsible for hauling and disposing of any excess cut in an appropriate manner. Once the <br />grading is complete, the site will be stabilized with permanent landscaping as well as seeding and <br />mulching. Refer to the plans for location and limits of the grading operations. <br />The site BMPs depicted on the plans is tentative and subject to change based on the condition <br />of the soils, fill requirements, and contractor's needs. Should additional or different BMPs <br />become necessary, the plans are to be revised to reflect the deviances from the approved plan <br />set. <br />The contractor is to communicate all deviations and revisions to CLC Associates, Inc. and the <br />Garfield County Engineering Division. The revisions are to be marked on the plans that are <br />posted in the construction trailer. <br />Page 1 <br />
