It covers a total of 1,174 square miles; approximately 1,017 square miles of land and 157 square miles of water. The three incorporated communities in Santa Rosa County are Milton, which is the county seat, Gulf Breeze and Jay. Unincorporated communities in the County include Chumuckla, Midway, Navarre, Navarre Beach, Oriole Beach, Bagdad and Pace. The County shares its western border with Escambia County, Florida across the Escambia River. Escambia County, Alabama borders on the north while Okaloosa County, Florida borders on the east. The southern border is the shoreline of the Gulf of Mexico. Santa Rosa County was established in 1842. Industry in the county is located in the greater Milton area. Incorporated in 1844, Milton is among the oldest cities in Florida. At that time the Blackwater River provided transportation for the timber, brick and shipbuilding industries that supported the area. Milton’s commercial opportunities were greatly expanded by the Arcadia mill and the L&N Railroad. As World War II approached, Milton was chosen as the site for NAS Whiting Field, and the community continues to embrace the service members and their families today. Milton is a progressive city that balances small town charm and modern urban life. The terrain of Santa Rosa County is varied. The southern portion is characterized mostly by sand hills and pine flatwoods with swampy areas along the rivers. The northern portion is almost exclusively rolling, forested hills with elevations reaching 300 feet. Eglin Air Force Base, in the southeastern corner of the county, is composed mostly of sand hills with swamp along the Yellow River. The five member Board of County Commissioners serves as the legislative and policy setting body for Santa Rosa County. As such, the Board enacts all legislation and authorizes programs and expenditures for the County. The Board appoints a professionally trained County Administrator, who is responsible for policy and budget development and implementation. CRS MAX CONSULTANTS, INC. November 2009; updated by SRC November 2015 Section 1 Page 1 Santa Rosa County Flood Mitigation Plan Section Two BACKGROUND AND PURPOSE Flood mitigation plans form the foundation for a community's long-term strategy to reduce flood losses and break the cycle of flood damage, followed by reconstruction, and repeated damage. It creates a framework for risk-based decision making to reduce damages to lives, property, and the economy from future floods. Flood mitigation is sustained action taken to reduce or eliminate long-term risk to people and their property from flooding. Local governments are required to develop a flood mitigation plan as a condition for receiving certain types of non-emergency disaster assistance. Santa Rosa County has developed a Flood Mitigation Plan that provides a comprehensive set of strategies for flood mitigation and includes a list of activities that can further mitigation goals. The purpose of this Flood Mitigation Plan is to: help reduce flood losses improve local flood hazard mitigation capability increase public and private sector awareness by educating about the hazards, loss reduction measures, and the natural and beneficial functions of floodplains address and protect cultural, economic and natural resources This Flood Mitigation Plan (FMP) is intended to accomplish this purpose and to promote a sustainable and flood-resistant community. The County’s efforts have demonstrated a strong commitment to flood mitigation and have served to minimize the impacts of flooding. There is an ongoing commitment to improvement that is further demonstrated by this plan. This Flood Mitigation Plan is intended to provide direction and to identify the actions necessary to advance the numerous facets of Santa Rosa County’s overall flood mitigation efforts. This Flood Mitigation Plan has been purposefully developed to be consistent with: the Santa Rosa County Local Mitigation Strategy 2005 – 2010 (LMS), the National Flood Insurance Program’s Community Rating System Floodplain Management Planning Process, and the Disaster Mitigation Act of 2000 Santa Rosa County Flood Mitigation Plan Section Two, Background and Purpose 2.1 Consistency with the Santa Rosa County Local Mitigation Strategy This Plan is consistent with the Santa Rosa County Local Mitigation Strategy 2005 – 2010 (LMS), and is intended to become an appendix to the Santa Rosa County 2010- 2015 LMS (as updated November 2015). Although the 2005 – 2010 LMS included a flood mitigation section, the County determined there was a need for strengthening this component of the strategy and incorporating increased public input as part of the plan development process. 2.2 Consistency with the Community Rating System Floodplain Management Planning Process In addition to serving as a guide recommending mitigation solutions to flooding, this document has also been prepared to qualify as a “floodplain management plan” under the Community Rating System (CRS). The National Flood Insurance Program's (NFIP) CRS was implemented in 1990 as a program for recognizing and encouraging community floodplain management activities that exceed the minimum NFIP standards. Under the CRS, flood insurance premium rates are discounted to reflect the reduced flood risk resulting from community activities that meet the three goals of the CRS: 1.
