<br />.. <br /> <br />The City indicated that it is willing to provide updated survey information where needed. <br />The City's photogrammetry contractor was present at the meeting and indicated that he <br />still had the ground control information from previous work. New aerial photography for <br />the whole study reach would cost about $4,000. <br /> <br />It was decided that the City would obtain new photogrammetric cross sections for the <br />reach of the Cache La Poudre between Ash Avenue and 25th Avenue along alignments <br />delineated by the Corps. The cross sections downstream of Ash Avenue and upstream of <br />25th Ave are believed to be okay, but these reaches will be included in the photography to <br />be obtained in case there have been significant changes anywhere in these reaches. City <br />survey crews will develop channel invert data and also obtain the bridge geometry. It <br />was recommended that horizontal coordinates for the top of bank locations on the cross <br />sections be obtained from the photogrammetry. The coordinates can then be used with <br />GPS receivers to locate the cross sections for the ground surveys. The aerial photography <br />would probably be taken in December. All surveys will be to NGVD29 datum. <br /> <br />I mentioned that there was a potential that the floodway delineated with the new cross <br />sections could be different and possibly wider than the floodway delineated in the FPMS <br />study. Because the revisions to the FPMS study are outside the scope of work ofthe CTP <br />study, a revised scope and cost estimate will be developed by the Corps. The CWCB <br />would then have to approach FEMA for funding the changes. <br /> <br />The following action items resulted from the meeting: <br /> <br />· City will have the aerial photography of the study reach flown as soon as <br />practicable, probably in December. <br /> <br />· Corps will provide the City with the cross section alignments for the new cross <br />sections between Ash Avenue and 25th Street. <br /> <br />· City will contract for photogrammetric delineation of new cross sections and <br />arrange for city crew to obtain channel bed and bridge surveys. <br /> <br />· Corps will provide CWCB with revised scope of work and cost estimate for the <br />additional analyses. <br /> <br />· CWCB will report to FEMA about the study problems and request additional <br />funds to complete the study. <br /> <br />
