'..,.....:-1 .-:(,'-;Y PART IV HAZARD MITIGATION OPPORTUNITIES AND RECOMMENDATIONS The Interagency Flood Hazard Mitigation Team discussed mitigation opportunities for hazards associated with flooding, including: inundation of land, structures, and facilities; damage caused by high ground water levels and salt contamination; sluffing and erosion of the river banks, mosquito infestation; water contamin- ation from sewage and other sources, and the potential for increased damage from tributary flooding in the area. ~r much discussion, the team decided it was not possible to formulate work programs to mitigate all the hazards and, therefore, concen- trated on those issues relating to federal agencies and where opportunities for mitiqation existed. The work programs in, Part V are the recommendations of the Inter- agency Hazard Mitigation Team and were the consensus of the participating members. Each of the eleven work programs consist of a work element followed by a background statement to further describe the issue and intent of the team, additional information on the agencies responsible for the action, financing, and a work schedule. Work programs 9-11 are provided for guidance to the Hazard Mitigation Coordinators, required by Section 406, P.L. 93-288. The federal and state Hazard Mitigation Coordinators will meet with local coordinators to explain the work proqrams and encouraqe implementation. An explanation of Section 406, P.L. 93-288 is included in Appendix A. The Bureau of Indian Affairs (DOl) will assist the federal Hazard Mitigation Coord- inator in working with Tribes. Two hazards, mosquito infestation and potential danoers nf tributary floodinq required immediate action and were addressed by special groups. The Federal Coordinating OfficerlDisaster Recovery Manager (FCO/DRM) tasked, through a mission assignment to the Center for Disease Control, Department of Health and Human Services, to assess the current and potential risk of mosquito- borne encephalitis as a result of flooding along the lower portion of the Colorado River. The results of this assessment are not available at this time. A special Flood Impact Task Force was established by the FCO/DRM to assess the short term impacts of other types of floodinq on the Colorado River. This Task Force was given the following assignments: 1. Determine the potential flash flood impact on the Colorado River by a) Identifying critical areas where people should be alerted to evacuate or take other protective measures; b)Determine what planning is in place for the six declared counties to prepare for potential flash floods; c) Identify deficiencies to these plans and recommend corrective action. These tasks are based on the assumption that the flows on the Colorado River are stablized. 16
