The project was performed <br />under the guidance of Douglas County Engineering (County). <br /> <br />Multiple tasks were accomplished in order to perform the assessment. A description of <br />these tasks are as follows. Interviews were held in order to obtain an inventory of <br />existing response agencies, flood detection resources, flood prediction resources, flood <br />warning resources, and communications resources involved in flood related actions and <br />activities within the project area. Existing hydrologic/hydraulic information within the <br />project area was obtained and reviewed for the purpose of identification of potential flood <br />hazard areas. A web site was developed that contains weather information that is <br />currently available on the Internet and is applicable to Douglas County. A flood <br />orientation was held for Douglas County agencies/departments that demonstrated the <br />existing weather detection, prediction and warning resources within Douglas County. <br /> <br />This report summarizes all of the tasks, assess existing flood related resources and <br />contains recommendations to enhance existing resources. <br /> <br />2.0 Interviews/Information Gathering <br /> <br />Interviews were held with local towns, county, state and federal agencies/departments <br />that have flood related responsibilities within the project area. Interview questionnaires <br />were prepared by HDR that contained a myriad of questions related to flood prediction, <br />flood detection, flood response, flood preparedness, flood warning, communications, and <br />incident management systems that were posed to the departments/agencies. The vast <br />majority of the interviews were conducted in-person, while the remainder of the <br />interviews were accomplished over the telephone or the questionnaires were filled out <br />and returned to HDR bye-mail, and/or facsimile. These interviews yielded useful <br />information that included, but was not limited to, the following with respect to flooding <br />events: <br /> <br />· Existing policies <br />· Existing procedures <br />. Existing weather/hydrologic detection resources and the flow of the <br />information <br />. Existing weather/hydrologic predictive information resources and the flow <br />of the information <br />. Existing weather warning resources and the flow of the information <br />· Existing communication infrastructure <br />. Existing interagency, interdepartmental, multi agency, and departmental <br />coordination <br />· Existing resource allocations <br />· Existing response actions <br />. Existing evacuation policies and procedures <br /> <br />1 <br />
