GREGG COUNTY AND THE CITIES OF CLARKSVILLE CITY, EASTON, GLADEWATER, KILGORE, LAKEPORT, LONGVIEW, WHITE OAK, AND THE EAST TEXAS COUNCIL OF GOVERNMENTS 2018 HAZARD MITIGATION ACTION PLAN Prepared by: Gregg County Hazard Mitigation Planning Committee Under Authority of: Gregg County Commissioners Court City Council of Clarksville City Easton City Council Gladewater City Council Kilgore City Council Lakeport City Council Longview City Council White Oak City Council East Texas Council of Governments Executive Committee Local Contact: Mark Moore, Gregg County EMC 903-236-8400 [email protected] Date submitted to TDEM: July 7, 2018 Date Submitted to FEMA: __________________________ Date approved by FEMA: ___________________________ Date first adopted: April 8, 2019 EXECUTIVE SUMMARY Natural hazards exist throughout Gregg County which have caused and will continue to cause loss of life and/or property damage. Many of these hazard events are unavoidable. The purpose of this Hazard Mitigation Action Plan is to reduce the potential for damage to the people and assets of our community due to natural hazards. This 2018 HMAP update replaces the 2013 Update which was adopted on September 7, 2013. The first section of the plan explains the purpose of the project and describes the process used to meet the goals, including the legislative authority. The second section gives a brief profile of Gregg County and its cities which are parties to this Plan: Clarksville City, Easton, Gladewater, Kilgore, Lakeport, Longview and White Oak, as well as the East Texas Council of Governments, which is also a party to this Plan. The third section of the plan contains the hazard identification and risk assessment. First, the hazards are identified and described, including the locations that are at risk from each hazard and extent of the hazard’s anticipated effects. Previous occurrences are detailed, and the probability of recurrence is estimated. Vulnerability of our people and their property, as well as the infrastructure and resources of the county, are examined. Development trends are analyzed and potential losses are estimated. Hazards are prioritized. The fourth section presents our Mitigation Strategy: the goals, objectives and actions that will be taken to mitigate the loss of life and property from the identified hazards. Specific mitigation actions focus on five areas: prevention, life safety, property protection, economic stability, and recovery. Mitigation is a sustained action; Gregg County communities are constantly involved in hazard mitigation, although mitigation efforts are not always well-documented. Another goal of this planning process was to recognize and document those mitigation actions. 2018 GREGG COUNTY HAZARD MITIGATION ACTION PLAN 3 The fifth section details how this plan will be maintained in the future, and how it will be integrated into other planning mechanisms. Public involvement throughout the mitigation process is critical, and this section also discusses ways to keep the public involved. The final section of the plan serves to document the planning process. This section details how the plan was prepared, who was involved, and how various local and state agencies worked together with the private sector and the public. The three appendices contain reference material: National Climatic Data Center Weather History, which includes detailed tables of storm data from January 1, 1950 through March 31, 2018; Additional Verification of Participation in the form of sign-in sheets from committee meetings and public meetings at which hazard mitigation topics were discussed during the writing of this updated Plan; and finally, the Adoption Resolutions to be passed by the various jurisdictions which are a party to this Plan. The Resolutions will be added after this revised and updated Plan is FEMA approved. 2018 GREGG COUNTY HAZARD MITIGATION ACTION PLAN 4 GREGG COUNTY LOCATOR MAP Source: http://www.texasfile.com/static/img/counties/Gregg_County_1000px.png 2018 GREGG COUNTY HAZARD MITIGATION ACTION PLAN 5 GREGG COUNTY JURISDICTIONS MAP This Gregg County jurisdictions map shows the locations of all participating cities, rural communities, major water features, airports and transportation hubs, as well as the positions of the four neighboring counties: Harrison, Rusk, Smith and Upshur.
