TOWN COUNCIL WORKSHOP AGENDA DOCUMENTATION PREPARATION DATE: March 10, 2009 SUBMITTING DEPARTMENT : Emergency Management MEETING DATE: March 16, 2009 DEPARTMENT DIRECTOR: Jason Biermann PRESENTERS: Jason Biermann and Barb Beck SUBJECT: Teton County/Town of Jackson Multi-Hazard Mitigation Plan (MHMP) Update PURPOSE OF WORKSHOP ITEM 1. Provide the Town Council information regarding the status of the quintennial update to the MHMP, its identified goals and projects; specifically, those pertaining directly to the Town Council and/or TOJ departments. 2. Receive input from the Town Council regarding the identified goals and projects, including additions or deletions. DESIRED OUTCOMES 1. A comprehensive, acceptable document. Ultimately, following approval by both the Wyoming Office of Homeland Security and FEMA, this document will need to be approved and adopted by the Town and County. In order to streamline the entire process, staff would like to implement any changes prior to submitting the plan to WOHS, etc. 2. An understanding of the proposed projects and the provision of preliminary guidance to staff regarding prioritization of the agreed upon tasks, so that implementation can begin as funding becomes available. BACKGROUND/ALTERNATIVES Background: FEMA requires all jurisdictions wishing to participate in its pre-disaster mitigation (PDM) grant program to approve and adopt a multi-hazard mitigation plan, and update the adopted plan every five years. In 2004, the Teton County Board of County Commissioners and the Jackson Town Council adopted the Teton County Hazards Mitigation Plan , a plan that was created internally. In 2008, TCEM contracted Beck Consulting to complete an objective update to the existing plan in accordance with current FEMA guidance with a scheduled adoption date of 2009. Alternatives: Failure to adopt the update within the five-year window can result in the loss of grant funding; however, the jurisdiction could decide to forgo the update and any potential associated revenue. ALIGNMENT WITH COUNCIL’S STRATEGIC INTENT This item directly supports the Council’s stated objective of “Governmental Consolidation”, especially definitions #3 and 4. Locally, our approach to addressing all phases of emergency management has been, and will continue to be, from the perspective that any large incident occurring in Town will affect the County and vice versa, and that in a time of disaster, we will certainly become a “single community”. Therefore, the MHMP, its goals and projects, are both multi-agency and multi-jurisdictional, and will require buy-in and participation from not only the Town and County, but our State and Federal partners as well. STAKEHOLDER ANALYSIS An advisory committee provided input to the consultant. This committee consisted of representatives from emergency management, Fire/EMS, law enforcement (Sheriff and PD), public works, transportation, and the Red Cross, in collaboration with State and Federal entities including the National Park Service and WYDOT. Finally, public participation was encouraged through three public meetings, as well as a seven-week comment period during which the draft MHMP was made available in both hardcopy and on-line. With the exception of a letter from the Geologists of Jackson Hole, public input was very limited. FISCAL IMPACT All projects listed were assigned a priority and cost (High, Medium, or Low) based upon definitions found on page 16.3. The fiscal impact to the Town and County will be subject to the elected officials’ discretion, i.e. which projects staff are directed to pursue. STAFF IMPACT Similar to the fiscal impact, staff impact will be directly related to the projects identified for completion. LEGAL ISSUES N/A ATTACHMENTS 1. Two (2) copies of draft MHMP made available to public dated December 2008. 2. Eight (8) copies of amended goals and projects dated February 27, 2009.
