In addition, we concur with your determination <br />that sites /isolated finds 5RT406, 5RT410, 5RT3070, 5RT3071 and 5RT3072 are not eligible for the <br />National Register of Historic Places (NRHP). Finally, we find that linear segment 5RT2749.2 <br />(incorrectly noted, at times, on the site form and report as 5RT2947.2) does not support the <br />eligibility of the entire linear resource. Assuming these sites will be avoided by the proposed project as <br />described in the report and that ground disturbing activities will stay within previously reclaimed areas <br />and /or within existing road right -of -way, we concur that a finding of no adverse effect is appropriate. <br />We would also like to offer the following project specific comments: <br />• As a number of these sites (specifically 5RT145, 5RT406, 5RT410 and 5RT487) were last <br />recorded 15 years ago (or more) we recommend that these sites be fully re- recorded to current <br />documentation standards, rather than simply discussed in the report. Having site information <br />that meets current documentation standards greatly facilitates our ability to comment on the <br />recommended determinations of eligibility. <br />• Please be sure to show all survey areas on the report maps even if they fall within portions of <br />the project area that were previously inventoried. Ideally the survey of both sides of Fish Creek <br />"200 to 300m in length depending on topography" should be documented so we may include <br />this information in our survey database. <br />.IVIC CENTER PLAZA 1560 BROADWAY SUITE 400 DENVER COLORADO 80202 www.historycolorado.org <br />
