before, during, or after a disaster to permanently eliminate or reduce the long‐term risk to human life and property from natural and man‐made hazards. Alger County has experienced various natural and man‐made hazards such as severe whiteout conditions along M‐28 and numerous ice and sleet storms that have closed schools and curtailed business activities. Hazard mitigation planning is a process that assesses risks and evaluates the community vulnerability from potential hazards. Deficiencies are identified and strategies are developed that help mitigate problem areas. By developing an effective hazard mitigation plan a community can potentially reduce the affects of a future disaster. Potential effects of a disaster include loss of lives and property, environmental and economical concerns, and reduced essential services and quality of life. The result of this plan process is an Action Plan that identifies the appropriate steps to help mitigate present and future hazards. Alger County’s Board of Commissioners adopted a hazard mitigation plan in 2007. This document serves as the five‐year mandatory review and update of the Alger County Hazard Mitigation Plan. 1.1 Background The Federal Emergency Management Agency (FEMA) provides hazard mitigation assistance to state and local governments and to individuals through programs under the Robert T. Stafford Act, Section 404 (Disaster Relief and Emergency Assistance). The Disaster Mitigation Act of 2000 (DMA2K) amended the Stafford Act, to require communities to have an approved Hazard Mitigation Plan in order to receive FEMA funding assistance. FEMA established project funding to develop local hazard mitigation plans. Part of these federal funds were allocated to the Michigan State Police/Emergency Management Division (MSP/EMD), which then re‐granted funding to Michigan counties and major municipalities to develop local hazard mitigation plans. A hazard mitigation plan must be approved by FEMA for disasters declared after November 1, 2004. Programs that provide federal assistance are: the Hazard Mitigation Grant Program (HMGP), Flood Mitigation Assistance Program (FMAP), and Pre‐Disaster Mitigation Program (PDMP). FEMA’s Hazard Mitigation Grant Handbook describes these three grant programs in detail. Alger County Hazard Mitigation Plan | Chapter 1 – INTRODUCTION ‐ Page 1 Alger County Hazard Mitigation Plan August 31, 2015- Approved by FEMA 1.2 Plan Process The Alger County Hazard Mitigation Plan process was given guidance by FEMA requirements and the Michigan Department of State Police‐Emergency Management Division (MSP/EMD) document – Pub 207, Local Hazard Mitigation Plan Workbook. The plan process is outlined below: Public Input is essential to the plan process in order to accurately understand the hazards faced by communities. Input into the plan was achieved through regular meetings and discussions with the County LEPC, Emergency Management Coordinator, local officials, and various agency personnel. Public participation takes place throughout the entire plan process and is described in more detail in Section 1.3. Public Input (Obtained throughout the process) Identify Hazards and Risks Define Goals Identify Strategies Select Evaluation Criteria Select Mitigation Strategies Draft Plan Adopt Final Plan and Begin Implementation The hazards and risks were identified through extensive research, meetings, surveys, and mapping. A community profile was first compiled to summarize the main components of the county and is explained in Section 2.0. Risks in the local units of government were described under three hazard categories: natural, technological, and social. A workgroup then rated the individual hazards to determine a high, moderate or low level of risk. Section 3.0: Hazards explains what went into the process and Table 3.1 shows the results. The goals and strategies focus on the higher‐risk hazards determined in part by the hazard identification process. The

Figure 1: Location of the Lake Copper shown in context with the generalized bedrock geology along the flank of the Midcontinent rift system (after Bornhorst and Lankton, 2009). 1 It was discovered in July of 1991 by local divers Bob Barron and Don Kauppi on the bottomlands of Lake Superior in about 30 feet of water northwest of Jacob’s Creek, Great Sand Bay between Eagle River and Eagle Harbor (Figure 1 and 2). The tabular Lake Copper was horizontal when discovered rather than vertical in the vein as it had fallen over.

  • Geology of Michigan and the Great Lakes
    35133_Geo_Michigan_Cover.qxd 11/13/07 10:26 AM Page 1 “The Geology of Michigan and the Great Lakes” is written to augment any introductory earth science, environmental geology, geologic, or geographic course offering, and is designed to introduce students in Michigan and the Great Lakes to important regional geologic concepts and events. Although Michigan’s geologic past spans the Precambrian through the Holocene, much of the rock record, Pennsylvanian through Pliocene, is miss- ing. Glacial events during the Pleistocene removed these rocks. However, these same glacial events left behind a rich legacy of surficial deposits, various landscape features, lakes, and rivers. Michigan is one of the most scenic states in the nation, providing numerous recre- ational opportunities to inhabitants and visitors alike. Geology of the region has also played an important, and often controlling, role in the pattern of settlement and ongoing economic development of the state. Vital resources such as iron ore, copper, gypsum, salt, oil, and gas have greatly contributed to Michigan’s growth and industrial might. Ample supplies of high-quality water support a vibrant population and strong industrial base throughout the Great Lakes region. These water supplies are now becoming increasingly important in light of modern economic growth and population demands. This text introduces the student to the geology of Michigan and the Great Lakes region. It begins with the Precambrian basement terrains as they relate to plate tectonic events. It describes Paleozoic clastic and carbonate rocks, restricted basin salts, and Niagaran pinnacle reefs. Quaternary glacial events and the development of today’s modern landscapes are also discussed.

  • Chronology of Michigan History 1618-1701
    CHRONOLOGY OF MICHIGAN HISTORY 1618-1701 1618 Etienne Brulé passes through North Channel at the neck of Lake Huron; that same year (or during two following years) he lands at Sault Ste. Marie, probably the first European to look upon the Sault. The Michigan Native American population is approximately 15,000. 1621 Brulé returns, explores the Lake Superior coast, and notes copper deposits. 1634 Jean Nicolet passes through the Straits of Mackinac and travels along Lake Michigan’s northern shore, seeking a route to the Orient. 1641 Fathers Isaac Jogues and Charles Raymbault conduct religious services at the Sault. 1660 Father René Mesnard establishes the first regular mission, held throughout winter at Keweenaw Bay. 1668 Father Jacques Marquette takes over the Sault mission and founds the first permanent settlement on Michigan soil at Sault Ste. Marie. 1669 Louis Jolliet is guided east by way of the Detroit River, Lake Erie, and Lake Ontario. 1671 Simon François, Sieur de St. Lusson, lands at the Sault, claims vast Great Lakes region, comprising most of western America, for Louis XIV. St. Ignace is founded when Father Marquette builds a mission chapel. First of the military outposts, Fort de Buade (later known as Fort Michilimackinac), is established at St. Ignace. 1673 Jolliet and Marquette travel down the Mississippi River. 1675 Father Marquette dies at Ludington. 1679 The Griffon, the first sailing vessel on the Great Lakes, is built by René Robert Cavelier, Sieur de La Salle, and lost in a storm on Lake Michigan. ➤ La Salle erects Fort Miami at the mouth of the St.
