~ i <br />Routt County Commissioners <br />June 4, 2001 <br />Page 6 of 8 <br />Delineation report that a new study of the Yampa River floodplain in the vicinity for the project site <br />is merited. AES recommends that independent consultant perform the study. If its determined that <br />the subject property is within the 100-year floodplain, the Applicant would then be required to file <br />for the appropriate federal and state permits. <br />Late Response <br />On the morning of June 4, 2001, 10:00 am Mr. R.C. Moon (Skidge) called AES and apologized <br />for not having returned our earlier telephone calls. We explained to Skidge that our response to <br />the Applicant's application was completed and that at such a late date we would not be able to <br />incorporate any additional information he may have. However, we did ask Skidge about the field <br />crass sections he surveyed across the subject property. Our questions were (1) did he get survey <br />shots in the center of the Yampa River and in the center of Trout Creek, and (2) did he know how <br />deep the channel sections aze in Yampa River and Trout Creek where the HEC-RAS model cross <br />sections are shown? <br />Skidge's response was (1) his responsibilities for the river cross sectional survey was only to <br />collect data where his rodman (Mr. Paul Currier) dictated they betaken; (2) he did not think there <br />were any field survey points taken in the center of the Yampa River. When the survey was <br />performed there was ice on the river and he recalled there were some survey shots that broke <br />through the ice at the edge of bank; (3) he did not recall if any survey shots were taken in the <br />center of Trout Creek; and (4) he did not review cr :vor k-up the data collected, instead he sent an <br />ASCII file of the data to Mr. Cumer. <br />Based this late response from Skidge, AES believes it is certainly the responsibility ofRoutt <br />County to now make a competent review of all survey mapping and compare it to the HEC-RAS <br />cross-sections submitted by the Applicant. <br />Sincerely, <br />Aquatic EServices, Inc. <br />~' <br />o~.~ , ~/ <br />' ~Q=n/ <br />P.L.S. <br />President <br />Copy: Loretta Van Norstand <br />
