<br />r <br /> <br />and land cover information from the U.S. Forest Service was most <br />helpful. The Colorado Water Conservation Board was also contacted. <br /> <br />A general information search was made at the State Historical <br />Society, the Denver Public Library, the Boulder County Courthouse, <br />and the Boulder Daily Camera for historical background information, <br />available publications, and photographs of past floods. <br /> <br />~ <br /> <br />~ <br /> <br />The final coordination meeting was held on August 7, 1978, and <br />was attended by representatives of the Federal Emergency Management <br />Agency, the study contractor and the town. All problems raised <br />at the meeting have been solved. <br /> <br />p <br /> <br />~ <br /> <br />2.0 AREA STUDIED <br /> <br />2.1 Scope of Study <br /> <br />This Flood Insurance Study covers the incorporated areas of the <br />Town of Jamestown, Boulder County, Colorado. The area of study <br />is shown on the Vicinity Map (Figure 1). <br /> <br />Floods caused by overflow of James Creek, Little James Creek, and <br />Unnamed Tributary to Little James Creek were studied by detailed <br />methods. <br /> <br />Those areas studied by detailed methods were chosen with consider- <br />ation given to all proposed construction and forecasted development <br />through 1983. <br /> <br />~ <br /> <br />o <br /> <br />2.2 Community Description <br /> <br />Jamestown is a small mountain community located in the central <br />northwest section of Boulder County, in the north-central portion <br />of Colorado, approximately 10 miles northwest of the City of <br />Boulder. The 1970 population was 185, and is currently estimated <br />at 240. Communities near Jamestown are Lyons, approximately <br />11 miles to the northeast, and Longmont, approximately 16 miles <br />to the east. <br /> <br />Historically a mlnlng town, Jamestown is now a residential community. <br />Most of its residents are commuters to either Boulder, Denver, <br />or Longmont. <br /> <br />~ <br /> <br />Little James Creek, draining an area of approximately 3 square <br />miles, joins James Creek at Jamestown. James Creek, with a drain- <br />age area of 14.5 square miles at the downstream study limit, <br />is a tributary to Lefthand Creek, which flows eastward to join <br />St. Vrain Creek near Longmont. Rainfall in the basin averages <br />nearly 24 inches annually. <br /> <br />i <br /> <br />s <br /> <br />~ <br /> <br />2 <br />
