Description: Base flood elevation lines indicate the rounded whole foot water-surface elevation of the 1 percent annual chance flood. Definition source: FEMA Guidelines and Specifications for Flood Hazard Mapping Partners, Appendix L: Guidance for Preparing Draft Digital Data and DFIRM Databases.The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual- chance flood event, and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA). In addition to the preceding, required text, the Abstract should also describe the projection and coordinate system as well as a general statement about horizontal accuracy.
Description: These lines represent the locations of channel surveys performed for input into the hydraulic model used to calculate flood elevations. These can be used to cross reference the flood profiles to the planimetric depiction of the flood hazards.

Description: The minor flowing water courses in St. Charles County, MO. Specifically minor water course areas include any flowing water bodies that there is an apparent visible width from 1ft resolution aerial photography. Does not include the Missouri and Mississippi Rivers. The water boundary extents to the water's edge at the time of the last aerial photo acquired by St. Charles County Government. The next scheduled update is early 2016. The datum is State Plane - Missouri East NAD 1983.
