3.5 Geology/Soils
3.5 GEOLOGY/SOILS 3.5.1 INTRODUCTION This section describes the project’s impacts related to geology and soils, including such factors as seismology, soils, topography, and erosion. It also includes an examination of potential hazards associated with potential damage to proposed structures and infrastructure from ground shaking, potential liquefaction hazards and soils and soils stability. Applicable laws, regulations and relevant local planning policies that pertain to geology are also discussed. Much of the information contained in this subsection was based upon the following geotechnical reports submitted by consultants under contract to the Chandler’s Palos Verdes Sand and Gravel Company and the peer review of those technical studies by Arroyo/Willdan Geotechnical: Geologic Constraints Investigation of the Chandler’s Inert Solid Land Fill Quarry and Surrounding Properties, Rolling Hills Estates, California, Earth Consultants International, June 15, 2000.

The Volume of the Complete Palos Verdes Anticlinorium: Stratigraphic Horizons for the Community Fault Model Christopher Sorlien, Leonardo Seeber, Kris Broderick, Doug Wilson Figure 1: Faults, earthquakes, and locations. Lower hemisphere earthquake focal mechanisms, labeled by year, are from USGS and SCEC (1994), with location of 1930 earthquake (open circle) from Hauksson and Saldivar (1986). The surface or seafloor traces, or upper edges of blind faults are from the Southern California Earthquake Center Community Fault Model (Plesch and Shaw, 2002); other faults are from Sorlien et al. (2006). Figure 2 is located by red dashed polygon. L.A.=Los Angeles (downtown); LB=Long Beach (city and harbor); PVA=Palos Verdes anticlinorium, Peninsula and Hills, PVF=Palos Verdes fault; SPBF=San Pedro Basin fault; SMM=Santa Monica Mountains; SPS=San Pedro Shelf. Structural Setting If the water and post-Miocene sedimentary rocks were removed, the Los Angeles (L.A.) area would have huge relief, most of which was generated in the Plio-Pleistocene (Fig. 1; Wright, 1991). The five km-deep L.A. basin would be isolated from other basins to the SW by a major anticline-ridge, the Palos Verdes Anticlinorium (PVA), parallel to the current NW-SE coastline (Davis et al., 1989; Figures 2, 3). The Palos Verdes Hills have been long recognized as a contractional structure, but of dimensions similar to the peninsula (e.g., Woodring et al., 1946). This prominent topographic feature is instead only the exposed portion of the much larger PVA (Fig 2). Submerged parts of the PVA had previously been interpreted as separate anticlines (Nardin and Henyey, 1978; Legg et al., 2004) related in part to bends in strike-slip faults (Ward and Valensise, 1994), rather than a single complex structure above low-angle (oblique) thrust faults. -

Changes are shown as follows: bold underline text for new text proposed to be added, strikethrough text for existing text proposed to be removed, and normal text for existing text to remain. 1 Palos Verdes Peninsula The City of Rancho Palos Verdes s located on the Palos Verdes Peninsula in the southwest tip of Los Angeles County. The City includes 12.3 square miles of land and 7-1/2 miles of coastline. One-third of the total land is vacant, with more than three-fourths of the immediate coastline land vacant. The Peninsula has a unique physiography, formed over millions of years of submerging and lifting from the Pacific Ocean. The residents of the Palos Verdes Peninsula are the beneficiaries of a unique geography, formed from millions of years of volcanic activity, plate tectonics and terracing from changing sea levels. The nine-mile wide Peninsula, once an island, the Peninsula, none miles wide by four miles deep, now rises above the Los Angeles Basin with a highest elevation at to a maximum of 1,480 feet, with uniquely terraced configurations and steep, rocky cliffs jutting upward 50 to 300 feet from the ocean. The forming of the Peninsula has resulted in the unique terrace configurations readily observable today and the steep, rocky cliffs at the ocean’s edge which rise from fifty to three hundred feet. Erosion has created contributed to the creation of numerous steep-walled canyons. -

1.1 Geography 486/586 Splansky and Laris 2005 PALOS VERDES PENINSULA I. HISTORY
1.1 Geography 486/586 Splansky and Laris 2005 PALOS VERDES PENINSULA I. HISTORY: DATES AND PLACE NAMES In 1602 Sebastian Vizcaino, sailing northward from Acapulco, re-named the bay east of the peninsula San Pedro Bay (viewed on the Feast Day of Saint Peter). Earlier, it had been named the "Bay of Smokes" by Juan Cabrillo. Vizcaino also referred to and charted the existence of the Palos Verdes (green stalks) observed to the west of the bay. In 1784, Rancho San Pedro was granted to Juan Jose Dominguez. This change in land ownership status represented the first private land grant in Alta California and it included the Palos Verdes peninsula. Subsequent carving up of the Rancho San Pedro created one portion named Rancho de Los Palos Verdes which was acquired by the son of Juan Jose Sepulveda. In 1792, George Vancouver, on his return voyage from the Canadian Pacific coast, met and liked Father Fermin Francisco de Lasuen while visiting the Carmel Mission. Vancouver also met and liked Friar Vicente Santa Maria while visiting the San Buenaventura Mission. In 1793, while rounding the Palos Verdes peninsula, he named and charted Points Vicente and Fermin after the two clerics. II. PALOS VERDES: GENERAL TERMINOLOGY AND INFORMATION The Palos Verdes Peninsula is a northwest trending dome-like ridge, 9 miles long and up to 5 miles wide. Its crest has gentling rolling topography at elevations ranging from 1480 to 1100 feet above sea level. Below this upland, remnants of a flight of Pleistocene marine terraces ring the peninsula and demonstrate it was an island during most of its geomorphic evolution. -

5-1 SECTION 5.1 INTRODUCTION the Conservation Element of The
SECTION 5.1 INTRODUCTION The Conservation Element of the Rolling Hills Estates General Plan is concerned with the management of natural and cultural resources in the planning area. The Element identifies significant resources within the City and establishes a plan for their conservation, management, or preservation. The Conservation Element is a state-mandated element as required by regulations in Section 65302(d) of the California Government Code and the State Mining and Reclamation Act (SMARA). The Element is intended to increase public awareness concerning the presence and condition of natural and cultural resources and to promote their conservation and management. The earth's resources are limited and often non-renewable. Ignorance, indifference and misuse could easily lead to their exploitation, destruction or neglect. As such, it is the City's responsibility to inform residents of the importance of local resources in relation to regional concerns. The City is empowered to regulate the use of certain local resources to prevent their destruction and exploitation and to ensure that conservation efforts are constant and equitable. Conservation includes the regulation of the extent of resource utilization, of the appropriate preservation techniques and of the conduct of activities which affect or preclude the use of resources. Natural resources in the planning area include water, air, and biotic resources. Cultural resources include historical , archeological and paleontological sites and structures. The City's conservation plan will consist of independent programs for the managed use of mineral resources, the maintenance of good air quality, the protection of native plant and animal life and the preservation of cultural resources. -
The Phylogenetic Relationships and Biogeography of True Porpoises (Mammalia: Phocoenidae) Based on Morphological Data

This study evaluates a comprehensive set of cranial, postcranial, and soft anatomical characters to infer interrelationships among extant species and several well-known fossil phocoenids, using two different methods to analyze polymorphic data: polymorphic coding and frequency step matrix. Our phylogenetic results con- firmed phocoenid monophyly. The division of Phocoenidae into two subfamilies previously proposed was rejected, as well as the alliance of the two extinct genera Salumiphocaena and Piscolithax with Phocoena dioptrica and Phocoenoides dalli. Extinct phocoenids are basal to all extant species. We also examined the origin and distri- bution of porpoises within the context of this phylogenetic framework. Phocoenid phylogeny together with available geologic evidence suggests that the early history of phocoenids was centered in the North Pacific during the middle Miocene, with 1 Current address: East Carolina University, Brody School of Medicine, Department of Anatomy and Cell Biology, 600 Moye Boulevard, Greenville, North Carolina 27834, U.S.A.
