(G&O). A revised hydraulic <br />analysis for South Boulder Creek was completed in July 1986 by G&O, <br />and was incorporated into this study. <br /> <br />The hydrologic and hydraulic analyses for the City of Lafayette and <br />the Towns of Jamestown, Lyons, Nederland, and Superior were <br />performed by Howard, Needles, Tammen & Bergendorff, for FBMA, under <br />Contract No. H-40l6. This work, which was completed in February <br />1978, covered all significant flooding sources affecting Lafayette, <br />Jamestown, Lyons, Nederland, and. Superior. <br /> <br />The hydrologic and hydraulic analyses for the initial study for the <br />City of Longmont were performed by Gingery Associates, Inc., for <br />FBMA, under Contract No. H-37l6. That work was completed in March <br />1976. <br /> <br />The additional hydrologic and hydraulic analyses for the City of <br />Longmont for the revised study were performed by Gingery <br />Associates, Inc., Simons, Lee IInd Associates, and Water Resources <br />Consultants, Inc., for the Colorado Water Conservation Board <br />(CWCB), as reported in floodplain information reports for Lefthand <br />Creek (References 1 and 2), and for Dry Creek No. 1 and St. Vrain <br />Creek (References 3 and 4, respectively). <br /> <br />f <br /> <br />2 <br />
