<br />The results of this study were reviewed at a final community <br />coordination meeting held on July 18, 1978. Attending the meeting <br />were representatives of the FIA, the study contractor, and the <br />city. This study incorporates all appropriate comments, and all <br />problems have been resolved. <br /> <br />. <br /> <br />The City of Longmont Engineeri.ng Department supplied zoning and <br />corporate boundary maps for use in the initial study for the City <br />of Longmont, as well as various detailed drawings for channel <br />improvements, such as final construction plans for the Spring Gulch <br />Linear Park and storm drainage facilities, dated January 1973, and <br />the structural plans for the Pratt Street bridge, over the St. <br />Vrain Creek. The City of Longmont Planning Department has supplied <br />a copy of the St. Vrain Comprehensive Plan (Reference 5), which <br />describes the comprehensive plan for what is called the Prime <br />Urbanized Area (PMA) of Longmont. The Planning Department also <br />provided a copy of the floodplain and floodway zoning ordinance, <br />and various historical aspects of flooding and community <br />development. Meetings were held with the City Planning and <br />Engineering Department's staff on July 23, 1974; May l4, 1975; and <br />December 30, 1975, to discuss detailed aspects regarding the <br />streams studied. <br /> <br />The USACE, Omaha District, provided mapping of the St. Vrain Creek <br />and parts of Lefthand Creek, Dry Creek No.1, and Spring Gulch <br />(Reference 6). Computer input regarding the hydrology and <br />hydraulic analyses for the St. Vrain Creek and Lefthand Creek were <br />also provided by the USACE. The floodplain information reports <br />completed by the USACE in January 1969 for Lefthand Creek <br />(Reference 7) and in June 1972 for Lower St. Vrain Creek (Reference <br />8) served as an important basis for comparison in this study. On <br />October l6, 1974, a conference was held with the USACE to gather <br />additional information on Longmont and to review potential <br />problems. <br /> <br />The USGS was contacted to obtain historic floodflow data <br />(References 9, 10, and 11). Maps of floodprone areas, prepared by <br />the USGS, showing approximate fLoodplain delineations at a scale of <br />1:2,400 were also reviewed (Reference 12). <br /> <br />At a meeting on August 27, 1974, attended by representatives of the <br />UDFCD, FEMA, and Gingery Associates, Inc., study reaches and <br />methods for the initial study were decided. An additional meeting <br />was held on January 24, 1975, in Washington, D.C., to further <br />clarify the purpose of the study and the methods used for <br />floodplain delineations. <br /> <br />Other agencies and individuals contacted for background information <br />included the CWCB, the Colorado Highway Department, and the <br />Longmont Dailv Times-Call newspaper. Private citizens of Longmont <br />were also interviewed regarding past floods, high-water marks, and <br />flood damage. <br /> <br />t <br /> <br />. <br /> <br />4 <br />
