    the California Desert CONSERVATION AREA PLAN 1980 as amended U.S. DEPARTMENT OF THE INTERIOR BUREAU OF LAND MANAGEMENT U.S. Department of the Interior Bureau of Land Management Desert District Riverside, California the California Desert CONSERVATION AREA PLAN 1980 as Amended IN REPLY REFER TO United States Department of the Interior BUREAU OF LAND MANAGEMENT STATE OFFICE Federal Office Building 2800 Cottage Way Sacramento, California 95825 Dear Reader: Thank you.You and many other interested citizens like you have made this California Desert Conservation Area Plan. It was conceived of your interests and concerns, born into law through your elected representatives, molded by your direct personal involvement, matured and refined through public conflict, interaction, and compromise, and completed as a result of your review, comment and advice. It is a good plan. You have reason to be proud. Perhaps, as individuals, we may say, “This is not exactly the plan I would like,” but together we can say, “This is a plan we can agree on, it is fair, and it is possible.” This is the most important part of all, because this Plan is only a beginning. A plan is a piece of paper-what counts is what happens on the ground. The California Desert Plan encompasses a tremendous area and many different resources and uses. The decisions in the Plan are major and important, but they are only general guides to site—specific actions. The job ahead of us now involves three tasks: —Site-specific plans, such as grazing allotment management plans or vehicle route designation; —On-the-ground actions, such as granting mineral leases, developing water sources for wildlife, building fences for livestock pastures or for protecting petroglyphs; and —Keeping people informed of and involved in putting the Plan to work on the ground, and in changing the Plan to meet future needs.

  • Section 3.11 Aesthetics Jan 11 02 SM Rev 4
    3.11 Aesthetics 3.11.1 Introduction and Summary This section presents the environmental setting and impacts related to aesthetic resources in the four geographic subregions. The aesthetic characteristics of an area are determined by the manner in which the resources contained in that area are perceived. Baseline aesthetic conditions are primarily described in terms of existing visual resources. Aesthetics discussions related to the Salton Sea also include a description of the olfactory character (odors) of that specific geographic subregion, which are briefly described below. Visual resources along the LCR include volcanic mountain ranges and hills; distinctive sand dunes; broad areas of the Joshua tree, alkali scrub, and cholla communities; and elevated river terraces (California Department of Water Resources [DWR] 1994). Views of the LCR occur at various locations along I-95. The IID water service area is characterized visually by substantial agricultural production and associated heavy machinery. Beyond the IID water service area, deserts, sand dunes, mountains, and the Salton Sea characterize the visual resources. Visual resources in the area of the Salton Sea geographic subregion include various landforms, vegetation, man-made structures, and the Sea itself. The Salton Sea covers approximately 211,000 acres (330 square miles) and is immediately surrounded by a sparsely vegetated desert landscape, which gives way to rocky, sandy hills (SSA and Reclamation 2000). The presence of odors at the Salton Sea currently affects both visitor numbers and resident populations in the area. Factors contributing to odors at the Salton Sea include water quality, high nutrient levels, and biological factors, such as fish and bird die-offs.

The views and conclusions contained in this document are those of the authors, and should not be interpreted as necessarily representing the official policies, either expressed or implied, of the U.S. Government. 1 Mapping the 3D Geometry of Active Faults in Southern California Abstract Accurate assessment of the seismic hazard in southern California requires an accurate and complete description of the active faults in three dimensions. Dynamic rupture behavior, realistic rupture scenarios, fault segmentation, and the accurate prediction of fault interactions and strong ground motion all strongly depend on the location, sense of slip, and 3D geometry of these active fault surfaces. Comprehensive and improved catalogs of relocated earthquakes for southern California are now available for detailed analysis. These catalogs comprise over 500,000 revised earthquake hypocenters, and nearly 200,000 well-determined earthquake focal mechanisms since 1981. These extensive catalogs need to be carefully examined and analyzed, not only for the accuracy and resolution of the earthquake hypocenters, but also for kinematic consistency of the spatial pattern of fault slip and the orientation of 3D fault surfaces at seismogenic depths.
