<br /> <br />After action reports and hazard analysis information are good <br />sources of information for the flood emergency planner. Specific <br />materials that fall into this category include: <br /> <br />-.j Historic Flood Information <br /> <br />-.j After Action Reports <br /> <br />-.j Flood Studies (Public & Private) <br /> <br />-.j Hazard Analysis Information <br /> <br />Notes <br /> <br />Record high water events are usually a once-in-a-lifetime <br />occurrence. Therefore, the flood emergency planner may have to <br />review historic documents and archives to learn about record or <br />near worst case events. At a minimum, information on the last <br />100-year flood should be gathered and reviewed. A good source <br />for historic information is the local newspaper archive. Other <br />sources can include historical societies and universities. This <br />information must be interpreted allowing for any changes, such as <br />the addition of water control systems, that have been added since <br />the last occurrence. <br /> <br />Information on 500-year flood events may have to be extrapo- <br />lated from geologic data and information. Universities and zoning <br />departments can help in obtaining and interpreting this informa- <br />tion. The Corps of Engineers may also be a good source for this <br />data. <br /> <br />After action reports provide extremely valuable information on <br />past high water events. Ideally, following a high water event, these <br />reports are gathered and compiled by one agency, but that is not <br />--. '..- - --~. --always the case. IndIvIdual agencIes and llepartrnems may havelO <br />be polled to find and obtain reports and information. But any time <br />spent in collecting this data is usually well worth the effort. <br /> <br />Flood studies may have been undertaken by planning agencies <br />or private development interests. These studies can range from <br />general overviews to highly scientific research reports. Informa- <br />tion on flood threats may be contained in other studies too. These <br />sources include: insurance reports, hazardous waste site investiga- <br />tions, subdivision reports, industrial development studies, bank and <br />underwriting reports, community development studies, and <br />renewal documents. The Federal Agricultural Natural Resource <br />Conservation.se~vice (ANRCS) may have detailed flood studies on <br />agricultural watersheds in and surrounding the community. <br /> <br />Page 2 - 7 <br />
