The City of Santa Barbara participated in the County wide Mitigation Advisory Committee (MAC), reviewed all portions of the previous hazard mitigation plan pertaining to the City, and incorporated relevant components into this plan. This plan serves as a complete hazard mitigation planning tool for the City of Santa Barbara. It contains updated capability assessment information, a new vulnerability assessment, and an updated/revised mitigation strategy. The methodology and process for developing this annex is explained throughout the following sections. Across the United States, natural and manmade disasters have led to increasing levels of death, injury, property damage, and interruption of business and government services. The impact on families and individuals can be immense and damages to businesses can result in regional economic consequences. The time, money and effort to respond to and recover from these disasters divert public resources and attention from other important programs and problems. Santa Barbara City, California recognizes the consequences of disasters and the need to reduce the impacts of natural hazards. The elected and appointed officials of the City also know that with careful selection, mitigation actions in the form of projects and programs can become a long-term, cost effective means for reducing the impact of natural hazards. The Santa Barbara City Hazard Mitigation Plan (the Plan), was prepared and formulated with input and coordination from the Mitigation Advisory Committee (MAC), with support from Santa Barbara County, City Office of Emergency Services and City Departments. The process to develop the Plan included nearly a year of coordination with representatives from each City department. The Plan guides the City of Santa Barbara toward greater disaster preparedness and resistance in harmony with the character and needs of its community. The City of Santa Barbara is located on the south coast of Santa Barbara County. Due to the Santa Ynez mountain range that blocks colder air from the north, Santa Barbara enjoys mild and pleasant weather. It sits at an elevation of roughly 50 feet above sea level and has a land area of 19 square miles. The city received its name when the California Mission Santa Barbara was founded there in 1786. The mission was known as the Queen of the Missions due to its beauty and the beauty of its surroundings. Attractions in Santa Barbara include the Waterfront, Downtown retail, entertainment and cultural districts, Santa Barbara Museums of Art and Natural History, the Santa Barbara Zoo, and special events such Old Spanish Days – Fiesta Santa Barbara. Santa Barbara is retail, tourism, government, education, and medical center of the County. It is home to the Santa Barbara Regional Airport, which provides commercial services for Ventura, Santa Barbara and San Luis Obispo Counties. Mitigation is commonly defined as actions taken to reduce or eliminate risks to people and property from hazards and their effects. Hazard mitigation focuses attention and resources on actions that will reduce or eliminate long term risks to persons or property from natural hazards. The impact of expected yet often unpredictable natural and human-caused events can be reduced through planning. History has demonstrated that it is less expensive to mitigate against disaster damage than to repeatedly repair damage in the aftermath. A mitigation plan states the aspirations and specific courses of action jurisdictions intend to follow to reduce vulnerability and exposure to future hazard events. 3 | Page It is the City’s hope the Plan continues to be used as a tool for all stakeholders to increase public awareness of local hazards and risks, while at the same time providing information about options and resources available to reduce those risks. Informing and instructing the public about potential hazards will help the City protect themselves against the effects of the hazards, and will enable informed decision making on where to live, play and locate homes and businesses. The emphasis of the Plan is on the assessment and avoidance of identified risks, implementing loss reduction measures for existing exposures and ensuring critical services and facilities survive a disaster. Hazard mitigation strategies and measures avoid losses by limiting new exposures in identified hazard areas, alter the hazard by eliminating or reducing the frequency of occurrence, divert the hazard by redirecting the impact by means of a structure or adapt to the hazard by modifying structures or standards. Federal legislation has historically provided funding for disaster
