Task 5 -Geologic Report: Prepaze a brief letter report with accompanying summaries, <br />figures and sketches, as appropriate, to comply with the intent of the County rezoning <br />requirement for submittal of geology information about the site (exclusive of natural <br />radioactivity conditions being handled by Elk Creek as part of a separate rezoning <br />exhibit). <br />Task 6 -Meetings with JeffCo: Attend two approximately one-hour meetings to <br />accommodate supporting you in ongoing discussions with the County about the geologic <br />and engineering aspects of the project <br />BACKGROUND <br />As part of recent County submittals, reviews and requests for additional information, we <br />understand that Ells Creek has been asked to submit a new "Geologic Report" confomring to <br />County guidelines. These guidelines are outlined on pages 27 and 28 of a County guidance <br />document excerpted by you and provided to us for reference. The parameters of the report as <br />outlined therein indicate that the document should include descriptions of, and possible <br />mitigation recommendations for, the following items: <br />1. General site geology; <br />2. General site topography; <br />3. Test borings or core samples; <br />4. Sites of special geologic interest; <br />5. Geologic hazards; and <br />6. Bedrock and surficial geology; <br />In addition, we proposed to perform additional surficial geologic mapping and general <br />stability analyses to evaluate proposed future mining of the hillside quarry to a slope <br />configuration of approximately IH:3V using standard stereonet-based stability evaluations. <br />The present scope of our work excluded performing geotechnical investigations such as test <br />borings because we believe that existing site historic information and exposures can be used to <br />adequately describe the elements of the Geologic Report without drilling, sampling or testing. <br />EVALUATIONS <br />The following sections provide updated narratives on the six geologic items listed above <br />(with parenffietic references to County Geologic Report requirements in bold for <br />reference). <br />A.
