  12. Title: Potential Aquifer Recharge Areas: Monterey County, California, 2001

    Contributors:

    Summary: This polygon shapefile contains areas for potential recharge of high to moderate infiltration capacity and low to moderate water holding capacity soils that overlie proven alluvial aquifers. These areas include Fort Ord/Seaside, parts of northern Monterey County, Carmel Valley, and the alluvial deposits along the Salinas River. Other areas include the alluvial fan deposits near Arroyo Seco. The alluvial fill in the San Antonio Valley area was also identified as highly favorable for recharge. Overlain on recharge areas are isohyetals (rainfall contours) of average annual precipitation. Blaney (1933) suggested threshold rainfall amounts that must occur to result in meaningful amounts of recharge for semi-arid climates similar to Monterey County. Blaney suggested a value of 17 inches per year of rainfall on native soils and 11 inches per year on irrigated fields. However, Blaney's analysis does not account for the anomalous distributions of annual rainfall (for example, a year where the rainfall total was 9 inches but it all fell in January), modeling efforts have shown the generalization relatively accurate. With the exception of the northern portion of North County and the San Antonio area, most of the identified recharge areas in Monterey County receive less than 17 inches of rainfall. In consideration of Blaney's generalizations, in these areas, even if soils are favorable, recharge from rainfall must be considered a rare occurrence and the importance of these areas as recharge areas is therefore limited. This layer is part of a collection describing Geology resources and constraints Monterey County, California. This map depicts areas of potential aquifer recharge for Monterey County, California. The intended use of this map is to provide a guide for use in regional planning studies of areas that provide recharge to aquifers. Rosenberg, Lewis, I. (2001).

  13. Title: Erosion Hazards of Monterey County, California, 2001

    Contributors:

    Summary: This polygon shapefile depicts hazardous areas of relative soil erosion for Monterey County, California. Erosion can be defined as the wearing away of the land surface by flowing water, waves, or wind, or by such process as mass wasting and corrosion. Water and wind erosion are important in assessing the health of the soil and in assessing the soil's potential for different uses. Removal of increasing amounts of soil increasingly alters various properties and capabilities of the soil. Properties and qualities affected include bulk density, permeability, organic matter content, tilth, and can degrade surface water quality. In Monterey County, farming is a major source of employment and revenue; hence, protecting the county's soil resources is important. This layer is part of a collection describing Geology resources and constraints Monterey County, California. The purpose of this map is to provide a comparison of relative soil erosion hazards for regional planning studies. County of Monterey, Environmental Resource Policy Department and Rosenberg, Lewis I. (2001). Erosion Hazards of Monterey County, California, 2001. Monterey County (Calif.) Planning Department. Available at: http://purl.stanford.edu/mv036hh3549.

  15. Title: Relative Seismic Shaking Hazards of Monterey County, California, 1999

    Contributors:

    Summary: This polygon shapefile depicts the seismic shaking level (peak ground acceleration) with a 10% probability of being exceeded in 50 years for Monterey County, California. Probabilistic seismic shaking maps are prepared using consensus information on historical earthquakes, faults, and geologic materials. A probabilistic seismic hazard map is a map that shows the hazard from earthquakes that geologists and seismologists agree could occur in California. It is probabilistic in the sense that the analysis takes into consideration the uncertainties in the size and location of earthquakes and the resulting ground motions that can affect a particular site. Historic earthquakes, areas damaged, the slip rates of major faults, and geologic materials were combined to calculate the shaking hazard for the peak ground acceleration. The shaking hazard maps show the level of ground motion that has 1 chance in 475 of being exceeded each year, which is equal to a 10% probability of being exceeded in 50 years. These levels of ground shaking are used primarily for formulating building codes and for designing buildings. Information used in preparing the data set was developed in cooperation with the U. S. Geological Survey. This layer is part of a collection describing Geology resources and constraints Monterey County, California. This purpose of this data set is to provide a regional perspective of earthquake ground shaking hazards in Monterey County. It is no tintended for site-specific hazard analysis, Rosenberg, Lewis, I.

  16. Title: Mineral Resource Zones of Monterey County, California, 1999

    Contributors:

    Summary: This polygon shapefile contains the distribution of Mineral Resource Zones for Monterey County, California. Construction minerals such as sand, gravel, and stone are classified by the State Geologist into four mineral resource zones based on the likelihood of the presence of mineral deposits and their economic value. The areas that contain minerals that can be economically extracted are classified as MRZ 2 and are essential for supplying aggregate used in residential, commercial, and industrial building projects, as well as in public-works projects such as roads, bridges, and pipelines. This layer is part of a collection describing Geology resources and constraints Monterey County, California. The intended use of this map is to provide a mineral resource zonation for regional planning studies. Rosenberg, Lewis I. (2001). Mineral Resource Zones of Monterey County, California, 1999.

  20. Title: Paleontological Resources of Monterey County, California, 2001

    Contributors:

    Summary: This point shapefile depicts paleontological resources within Monterey County, California. Fossils provide important evidence to help determine what happened in Earth history and when it happened. Today the animals and plants that live in the ocean are very different from those that live on land, and the animals and plants that live in one part of the ocean or on one part of the land are very different from those in other parts. Similarly, fossil animals and plants from different environments are different. It becomes a challenge to recognize rocks of the same age when one rock was deposited on land and another was deposited in the deep ocean. Scientists must study the fossils from a variety of environments to build a complete picture of the animals and plants that were living at a particular time in the past (Edwards and Pojeta, 1999). Because fossils are so useful to science, they need to be considered a resource and properly managed. The purpose of this database is to provide information on the type of fossil and the location so that these fossils may be preserved for science. Rosenberg, Lewis, I. and Clark, Joseph C. (2001).
