Book Description
Like ocean beaches, sheltered coastal areas experience land loss from erosion and sea level rise. In response, property owners often install hard structures such as bulkheads as a way to prevent further erosion, but these structures cause changes in the coastal environment that alter landscapes, reduce public access and recreational opportunities, diminish natural habitats, and harm species that depend on these habitats for shelter and food. Mitigating Shore Erosion Along Sheltered Coasts recommends coastal planning efforts and permitting policies to encourage landowners to use erosion control alternatives that help retain the natural features of coastal shorelines.

Book Description
The problem of land management along the coastal shoreline is an important one for the American public, whose already extraordinary recreational demands on this limited space are expected to nearly triple by the turn of the century. "Shoreline for the Public" notes that the institutional mechanisms operating over the past three centuries to allocate scarce coastal resources among competing users have brought unchecked private development to America's coasts. Compounded by problems of pollution, erosion, and the increasing tendency of private owners to restrict public access, this trend has resulted in severe limitations on opportunities for public recreation.The Coastal Zone Management Act of 1972 proclaims a national interest in the problem of decreasing public recreational space in the face of mushrooming demand. This study discusses the social significance of the problem, outlines the causes of coastal mismanagement in terms of the organization of economic and political activity, and examines in detail the legal issues pertinent to the formation of public policy. Included are analyses of the legal regimes governing public versus private rights in seashore areas, the judicial application of common-law principles to secure public recreational rights, shoreline acquisition, and the application of land-use controls to regulate shoreline development. The author concludes that a number of legal techniques "can" be made effective in preserving the seashore as a unique recreational resource for public use.While concentrating on the narrow land-sea strip, "Shoreline for the Public" raises larger issues facing environmental resource management. Decreasing open space for public recreation is prototypical of the complexity of coastal resource management issues. The problems cannot be solved solely by judicial activity but will require coherent and orderly long-range legislative and administrative management to make equitable and efficient choices among policy alternatives. Bringing public recreation, private use, and conservation into balance will require the application of new techniques at the interfaces between government and the courts, between government and the citizenry, and between different levels of government.

Book Description
Tide gauges show that global sea level has risen about 7 inches during the 20th century, and recent satellite data show that the rate of sea-level rise is accelerating. As Earth warms, sea levels are rising mainly because ocean water expands as it warms; and water from melting glaciers and ice sheets is flowing into the ocean. Sea-level rise poses enormous risks to the valuable infrastructure, development, and wetlands that line much of the 1,600 mile shoreline of California, Oregon, and Washington. As those states seek to incorporate projections of sea-level rise into coastal planning, they asked the National Research Council to make independent projections of sea-level rise along their coasts for the years 2030, 2050, and 2100, taking into account regional factors that affect sea level. Sea-Level Rise for the Coasts of California, Oregon, and Washington: Past, Present, and Future explains that sea level along the U.S. west coast is affected by a number of factors. These include: climate patterns such as the El Niño, effects from the melting of modern and ancient ice sheets, and geologic processes, such as plate tectonics. Regional projections for California, Oregon, and Washington show a sharp distinction at Cape Mendocino in northern California. South of that point, sea-level rise is expected to be very close to global projections. However, projections are lower north of Cape Mendocino because the land is being pushed upward as the ocean plate moves under the continental plate along the Cascadia Subduction Zone. However, an earthquake magnitude 8 or larger, which occurs in the region every few hundred to 1,000 years, would cause the land to drop and sea level to suddenly rise.
