  • Fremont Earthquake Exhibit WALKING TOUR of the HAYWARD FAULT (Tule Ponds at Tyson Lagoon to Stivers Lagoon)
    Fremont Earthquake Exhibit WALKING TOUR of the HAYWARD FAULT (Tule Ponds at Tyson Lagoon to Stivers Lagoon) BACKGROUND INFORMATION The Hayward Fault is part of the San Andreas Fault system that dominates the landforms of coastal California. The motion between the North American Plate (southeastern) and the Pacific Plate (northwestern) create stress that releases energy along the San Andreas Fault system. Although the Hayward Fault is not on the boundary of plate motion, the motion is still relative and follows the general relative motion as the San Andreas. The Hayward Fault is 40 miles long and about 8 miles deep and trends along the east side of San Francisco Bay. North to south, it runs from just west of Pinole Point on the south shore of San Pablo Bay and through Berkeley (just under the western rim of the University of California’s football stadium). The Berkeley Hills were probably formed by an upward movement along the fault. In Oakland the Hayward Fault follows Highway 580 and includes Lake Temescal. North of Fremont’s Niles District, the fault runs along the base of the hills that rise abruptly from the valley floor. In Fremont the fault runs within a wide fault zone. Around Tule Ponds at Tyson Lagoon the fault splits into two traces and continues in a downwarped area and turns back into one trace south of Stivers Lagoon. When a fault takes a “side step” it creates pull-apart depressions and compression ridges which can be seen in this area. Southward, the fault lies between the 1 lowest, most westerly ridge of the Diablo Range and the main mountain ridge to the east.

PROPOSALS DUE: JUNE 16, 2021 by 5 PROPOSALS P.M. PACIFIC DAYLIGHT TIME #RFP-2021-10 Request for Proposals Coyote Valley Conservation Areas Master Plan Background Purpose of Request for Proposals (RFPs) The Santa Clara Valley Open Space Authority (“Authority”) is soliciting proposals for professional services for the Coyote Valley Conservation Areas Master Plan (“Master Plan”). The Authority is seeking a consultant team to provide a comprehensive spectrum of skills and expertise needed to create an innovative, integrated, science- based, community-informed plan for the recently conserved lands in Coyote Valley; a unique natural and rural landscape, within an urban setting, located between the cities of San Jose and Morgan Hill, in Santa Clara County, California. The Authority is seeking proposals from an experienced prime firm and their subconsultants that would be responsible for conducting the work outlined in this RFP, culminating in a final Master Plan document and construction documents for the first round of implementation projects identified through the planning process. Consultant work will be authorized and funded on as “as needed” basis over the course of a six-year term through a series of Authority-authorized task orders. The selected firms will be asked to respond to any number of task orders, issued as the planning process progresses and funding is available.

  • DEPARTMENT of the INTERIOR U.S. GEOLOGICAL SURVEY Review of the Great Valley Sequence, Eastern Diablo Range and Northern San
    DEPARTMENT OF THE INTERIOR U.S. GEOLOGICAL SURVEY Review of the Great Valley sequence, eastern Diablo Range and northern San Joaquin Valley, central California by J. Alan Bartow1 and TorH.Nilsen2 Open-File Report 90-226 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards or with the North American Stratigraphic Code. Any use of trade, product, firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. 1990 , Menlo Park, California 2Applied Earth Technologies, Inc, Redwood City, California ABSTRACT The Great Valley sequence of the eastern Diablo Range and northern San Joaquin Valley consists of a thick accumulation of marine and nonmarine clastic rocks of Jurassic to early Paleocene age deposited in a forearc basin that was situated between the Sierran magmatic arc to the east and the Franciscan subduction complex to the west. In the western part of the basin, the sequence rests conformably on the Jurassic Coast Range Ophiolite or is faulted against the structurally underlying Franciscan Complex. Beneath the eastern San Joaquin Valley, the sequence unconformably onlaps igneous and metamorphic rocks of the Sierran magmatic arc. The sequence generally thickens westward to as much as 8-9 km in the Diablo Range, where it is unconformably overlain by late Paleocene and younger strata. The stratigraphy of the Great Valley sequence has been the subject of much work, but problems, particularly nomenclatural, remain. Lithostratigraphic subdivisions of the sequence have not gained widespread acceptance because of the lenticularity of most sandstone bodies, abrupt fades changes in subsurface and outcrops, and the lack of detailed subsurface information from closely spaced or deep wells.

  • Quaternary Geology of Alameda County, and Parts of Contra Costa
    U.S. DEPARTMENT OF THE INTERIOR TO ACCOMPANY MAP OF97-97 U.S. GEOLOGICAL SURVEY QUATERNARY GEOLOGY OF ALAMEDA COUNTY, AND PARTS OF CONTRA COSTA, SANTA CLARA, SAN MATEO, SAN FRANCISCO, STANISLAUS, AND SAN JOAQUIN COUNTIES, CALIFORNIA: A DIGITAL DATABASE By E.J. Helley and R.W. Graymer DISCUSSION INTRODUCTION Alameda County is located at the northern end of the Diablo Range of Central California. It is bounded on the north by the south flank of Mount Diablo, one of the highest peaks in the Bay Area, reaching an elevation of 1173 meters (3,849 ft). San Francisco Bay forms the western boundary, the San Joaquin Valley borders it on the east and an arbitrary line from the Bay into the Diablo Range forms the southern boundary. Alameda is one of the nine Bay Area counties tributary to San Francisco Bay. Most of the country is mountainous with steep rugged topography. Alameda County is covered by twenty-eight 7.5' topographic Quadrangles which are shown on the index map (alq_quad or Sheet 2). The Quaternary deposits in Alameda County comprise three distinct depositional environments. One, forming a transgressive sequence of alluvial fan and fan-delta facies, is mapped in the western one-third of the county. The second, forming only alluvial fan facies, is mapped in the Livermore Valley and San Joaquin Valley in the eastern part of the county. The third, forming a combination of Eolian dune and estuarine facies, is restricted to the Alameda Island area in the northwestern corner of the county. MAPPING METHODS 1 Geological units were mapped on 1:24,000 scale U.S.
