Background: Hazard Mitigation Planning for the Ada County Planning Area: In June 2021,a coalition of Ada County planning partners embarked on a planning process to prepare for and lessen the impacts of specified natural hazards. Responding to federal mandates in the Disaster Mitigation Act of 2000,the partnership was formed to pool resources and create a uniform hazard mitigation strategy that can be consistently applied to the defined planning area and used to ensure eligibility for specified grant funding sources. The 21-member planning partnership that completed this plan update process includes • Ada County • Eagle Fire District • Meridian (Unincorporated) . Eagle Sewer District Development • City of Boise • Eagle Urban Renewal Agency Corporation • City of Eagle • Flood Control District#10 • North Ada Co. Fire • City of Garden City • Greater Boise Auditorium and Rescue • City of Kuna District • Star Joint Fire • City of Meridian • Independent School District of Protection District • City of Star Boise • Star Sewer District • Ada County • Joint School District#2 • Whitney Fire Highway District • Kuna Rural Fire Protection Protection District District The planning area for the hazard mitigation plan encompasses all of Ada County.The result of the organizational efforts has been to produce a Federal Emergency Management Agency (FEMA) and the Idaho Office of Emergency Management(IOEM) approved multi-agency multi-hazard mitigation plan. Page 1 of 2 The hazard identification and profiling in the hazard mitigation plan addresses the following natural hazards considered to be of significant importance within the Ada County planning area: • Dam/canal failure • Flood • Drought • Landslide • Earthquake • Volcano (ash fall) • Extreme Weather • Wildfire Ada County Emergency Management&Community Resilience (EMCR) secured funding for developing the hazard mitigation plan and was the lead coordinating agency for this multi- jurisdictional effort. All participating local jurisdictions have been responsible for assisting in the development of the hazard and vulnerability assessments and the mitigation action strategies for their respective jurisdictions and organizations. Meridian's hazard mitigation planning team consists of members from Fire, Planning and Public Works. The overall plan update process was overseen by a 19-member,stakeholder Steering Committee with Meridian represented by Jason Korn. In addition, residents were asked to contribute by sharing local knowledge of their individual area's vulnerability to natural hazards based on past occurrences. Public involvement has been solicited via a multi-media campaign that included public meetings,web-based information, questionnaires,and progress updates via the news media. NEXT STEPS Why adopt this Plan? Once the hazard mitigation plan has been approved by IOEM and FEMA and adopted by all of the jurisdictional partners,the partnership will collectively and individually become eligible to apply for hazard mitigation project funding from the suite of grant programs under FEMA's Hazard Mitigation Assistance (HMA) program.The Plan needs to be adopted as the final step in the process. Where do we go from here? Meridian will need to adopt Volume 1 and respective annex by resolution to be eligible to apply for funding sources including grants. Grant funds are made available to local governments and states and can be used to implement the various hazard mitigation measures specified in the respective annexes. Meridian currently has a grant application under review for Ninemile Creek Mitigation. Due to the previous plan being expired,the Ninemile Creek application received an extraordinary circumstances extension to remain eligible as long as the new plan is adopted according to schedule. The Hazard Mitigation Plan is considered a living document, such that as awareness of additional hazards develop and new strategies and projects are conceived to offset or prevent loss due to natural hazards,the Plan will be evaluated and revised on an annual basis during the 5 year plan timeframe.

Downtown Meridian is approximately 10 miles from the heart of Boise. Meridian is favored by a mild, and climate. July is the hottest month,with the average high temperature of 90'F. January is the coldest month with an average low temperature of 22'F. The normal precipitation pattern in the Meridian area shows a winter high of 1.2 inches of precipitation per month and a very pronounced summer low of about 0.1 inches. Typically,there are 12 inches of annual precipitation. 6.2.2 History The City of Meridian was incorporated in August 1903. Meridian has transformed from a sagebrush-filled mail drop located on the Oregon Trail in the 1880s,to a small fruit orchard center after the turn of the century through the 1930s,to a dairy-based farming community in the 1940s. Meridian is named for Idaho's principle meridian TETRA TECH 6-1 2022 Ada County Multi-Hazard Mitigation Plan City of Meridian used for the initial survey of the state which coincides with Meridian Road at the center of the City. Its character as a small farming community continued until approximately 1990,when its population was still about 10,000. 6.2.3 Governing Body Format Meridian uses the Mayor-Council form of local government. In Meridian,the Council,which includes the Mayor, possesses both legislative and executive authority. Departments include: City Clerk, Community Development, Finance,Fire,Human Resources,Legal,Mayor's Office,Parks&Recreation,Police, and Public Works. The City Council is responsible for the adoption of this plan, City Departments are responsible for its implementation. 6.3 CURRENT TRENDS 6.3.1 Population According to COMPASS,the population of the City of Meridian as of April 2022 was 133,470. Since 2017,the population has grown at an average annual rate of 7.2 percent. 6.3.2 Development As of November 2021, single family housing is the predominant development in Meridian, accounting for 82%of all dwelling units. Additionally, at the end of 2021,Meridian provided 21%of available jobs in Ada County, or 53,035. Meridian seeks to offer a diversity of housing products, create strong and sustainable jobs, improve infrastructure, and support diversified modes of transportation. Identifying previous and future development trends is achieved through a comprehensive review of permitting since completion of the previous plan and in anticipation of future development. Tracking previous and future growth in potential hazard areas provides an overview of increased exposure to a hazard within a community. Table 6-2 summarizes development trends in the performance period since the preparation of the previous hazard mitigation plan, as well as expected future development trends. Table 6-2.

This section identifies where such integration is already in place, and where there are opportunities for further integration in the future. Resources listed at the end of this annex were used to provide information on integration. The progress reporting process described in Volume 1 of the hazard TETRA TECH 6-7 2022 Ada County Multi-Hazard Mitigation Plan City of Meridian mitigation plan will document the progress of hazard mitigation actions related to integration and identify new opportunities for integration. 6.5.1 Existing Integration Some level of integration has already been established between local hazard mitigation planning and the following other local plans and programs: • City of Meridian Comprehensive Plan—The Comprehensive Plan for Meridian currently includes mitigation related policies as they related to the protection of human life and property from flood events. Additionally,the Comprehensive plan addresses the need for natural resource protection and the identification of known hazards within the County. • Meridian Flood Damage Prevention Ordinance Ordinance integrates with Ada County Multi-Hazard Mitigation Plan goals and objectives. • COOP—The COOP plan for the City of Meridian was completed in 2012 and adopted by City Council. 6.5.2 Opportunities for Future Integration The capability assessment presented in this annex indicates opportunities to integrate this mitigation plan with other jurisdictional planning/regulatory capabilities. Capabilities were identified as integration opportunities if they can support or enhance the actions identified in this plan or be supported or enhanced by components of this plan. The capability assessment identified the following plans and programs that do not currently integrate hazard mitigation information but provide opportunities to do so in the future: • Comprehensive Plan Existing Conditions Report(ECR)—Integrate mitigation plan risk assessment into hazardous areas section and reference mitigation actions in specific hazard sections. • Comprehensive Financial Plan (CFP)—Mitigation may be funded, in part,through the City CFP plan and if grant funds are awarded for mitigation they need to be programmed into the CFP. Taking action to integrate each of these programs with the hazard mitigation plan was considered as a mitigation action to include in the action plan in this annex. 6.6 RISK ASSESSMENT 6.6.1 Jurisdiction-Specific Natural Hazard Event History Table 6-10 lists past occurrences of natural hazards for which specific damage was recorded in this jurisdiction Other hazard events that broadly affected the entire planning area, including this jurisdiction, are listed in the risk assessments in Volume 1 of this hazard mitigation plan. 6.6.2 Hazard Risk Ranking Table 6-11 presents a local ranking of all hazards of concern for which this hazard mitigation plan provides complete risk assessments. As described in detail in Volume 1,the ranking process involves an assessment of the likelihood of occurrence for each hazard, along with its potential impacts on people,property and the economy. Mitigation actions target hazards with high and medium rankings. 6-8 TETRA TECH 2022 Ada County Multi-Hazard Mitigation Plan City of Meridian Table 6-10.
