Description

The original source was the inundated areas as drawn by the National Geospatial Agency, which only covered major flooding along Boulder Creek and St Vrain Creek. This was supplemented by Boulder County Land Use and Parks and Open Space using imagery from the Digital Globe First Look product. Multiple images, taken on different days were used to determine the high water mark due to cloud cover. The high water mark has not been field verified. Inundated areas in the mountains were particularlly difficult to draw due to cloud and tree cover. Areas within the City of Longmont and Boulder were not drawn as it is assumed these cities will be creating their own layer. Areas within the other incorporated areas were drawn: Jamestown, Lyons, Louisville, Lafayette, and Erie. This dataset has further been refined by using Pictometry imagery flown October 2013 after the flood and using damage assessment data points. This dataset is updated as of 8/6/2014.
