GENERAL PLAN Low Density Residential (R1) DESIGNATION: ZONING: Planned Development EXISTING LAND USE: Undeveloped with graded building pads PROJECT SUMMARY The proposed project site is located in a low density residential area approximately 3.5 miles east of downtown Novato, 1.3 miles northeast of the Hwy 37 Petaluma River bridge, and 0.84 mile from the Petaluma River. The site consists of Assessor’s Parcel Number 143-272-07 and is located at the end of Misty Road in Novato, California. The proposed project would include the development of nine single-family homes on a vacant 8.7-acre hillside parcel which would begin low on the hillside and rise upward above Topaz Drive and sit below the upper ridgelines of this hillside. The homes would be one or two stories, range from 2,730 to 3,569 square feet, and would be between 21 feet and 27 feet, 2 inches in height. The nine lot areas range from 0.32 acre to 3.59 acre. Four different floor plans would be constructed, including both one- story and two-story designs. Houses would have dedicated two- and three-car garages attached to the units. On-street parallel parking is located on the north side of Misty Road, and 5 on-street parking spaces are located on the south side of Misty Road in two separate parking Bahia Heights Residential Subdivision December 2017 Initial Study Page i bays. The project would include the construction of necessary infrastructure improvements to serve the proposed subdivision, including installation of water and sewer lines, tree removal, the extension of Misty Road including additional sidewalk, drainage improvements, followed by the completion of all required site improvements on individual lots and the construction of the nine residences. There would also be installation of individual lot landscaping in the project development including a four-foot landscaping strip on the northern side of the street between the sidewalk and the street, and six to 14-foot wide landscape strips on the southern side of the street. No sidewalks are proposed for the southern side of the street. The proposed project site is surrounded by single-family residential development and is within the existing Bahia Subdivision. The project is located on an undeveloped hillside which was previously graded with individual building pads. Sixteen and 8/10th percent (16.8%) of the parcel is in the 0-10% slope range, 15.3% in the 10-25% range and 67.9% is greater than 25% slope. The project site is accessible through an existing roadway network. Access to the Bahia Subdivision and to the proposed nine lots would be through Atherton Avenue onto Bugeia Lane to Bahia Drive and Topaz Drive. The subdivision would be served from an extension of Misty Road. The closest highways to the proposed project site are U.S. Route 101 and Highway 37. There are currently no trails for viewshed at the proposed project site. The closest schools are Olive Elementary School, which is approximately 3.2 miles from the proposed site, and Marin Oaks High School, which is approximately 4.5 miles from the proposed project site. San Marin High School is 5.3 miles from the site. Novato High School is 5.2 miles from the project site. Sinaloa Middle School is 5.2 miles from the project site.

  • Introduction San Andreas Fault: an Overview
    Introduction This volume is a general geology field guide to the San Andreas Fault in the San Francisco Bay Area. The first section provides a brief overview of the San Andreas Fault in context to regional California geology, the Bay Area, and earthquake history with emphasis of the section of the fault that ruptured in the Great San Francisco Earthquake of 1906. This first section also contains information useful for discussion and making field observations associated with fault- related landforms, landslides and mass-wasting features, and the plant ecology in the study region. The second section contains field trips and recommended hikes on public lands in the Santa Cruz Mountains, along the San Mateo Coast, and at Point Reyes National Seashore. These trips provide access to the San Andreas Fault and associated faults, and to significant rock exposures and landforms in the vicinity. Note that more stops are provided in each of the sections than might be possible to visit in a day. The extra material is intended to provide optional choices to visit in a region with a wealth of natural resources, and to support discussions and provide information about additional field exploration in the Santa Cruz Mountains region. An early version of the guidebook was used in conjunction with the Pacific SEPM 2004 Fall Field Trip. Selected references provide a more technical and exhaustive overview of the fault system and geology in this field area; for instance, see USGS Professional Paper 1550-E (Wells, 2004). San Andreas Fault: An Overview The catastrophe caused by the 1906 earthquake in the San Francisco region started the study of earthquakes and California geology in earnest.

  • Western States Seismic Policy Council Policy Recommendation 18-3
    WESTERN STATES SEISMIC POLICY COUNCIL POLICY RECOMMENDATION 18-3 Definitions of Recency of Surface Faulting for the Basin and Range Province Policy Recommendation 18-3 WSSPC recommends that each state in the Basin and Range physiographic province (BRP), through consultation with state and federal geological surveys and other earthquake-hazard experts, define scientifically and societally relevant categories for recency of surface faulting (generally earthquake magnitude ≥M 6.5). WSSPC further recommends that in the absence of information to the contrary, all Quaternary faults be considered to have the recency of activity documented in the USGS Quaternary fault and fold database until more adequate data can be developed. Executive Summary Fault recency definitions are limited to the Quaternary because this period of geologic time is considered by the scientific community to be most relevant to paleoseismic studies of earthquake faults (Machette and others, 2004). The recency class of a fault is the youngest class based on the demonstrated age of most recent surface faulting. Latest Pleistocene-Holocene faults are included within the definition of late Quaternary faults, and both latest Pleistocene-Holocene and late Quaternary faults are included in Quaternary faults. Establishment/definition of surface-faulting recency categories are based on the ways that faults are portrayed on geologic maps and on the availability of geologic data in the BRP. Policy makers (owners, regulators, governmental agencies) should consult with state and federal geological surveys and other earthquake-hazard experts in using these recency categories and additional geologic data in developing definitions of hazardous faults to be considered in planning for development or infrastructure projects.

  • Late Quaternary Faulting in the Kaikoura Region, Southeastern Marlborough, New Zealand
    AN ABSTRACT OF THE THESIS OF Russell J. Van Dissen for the degree of Master of Science in Geology presented on February 15, 1989. Title: Late Quaternary Faulting in the Kaikoura Region, Southeastern Marlborough, New Zealand Redacted for privacy Abstract approved: Dr. Robert 8.0eats Active faults in the Kaikoura region include the Hope, Kekerengu, and Fidget Faults, and the newly discovered Jordan Thrust, Fyffe, and Kowhai Faults. Ages of faulted alluvial terraces along the Hope Fault and the Jordan Thrust were estimated using radiocarbon-calibrated weathering-rind measurements on graywacke clasts. Within the study area, the Hope Fault is divided, from west to east, into the Kahutara, Mt. Fyffe, and Seaward segments. The Kahutara segment has a relatively constant Holocene right-lateral slip rate of 20-32 mm/yr, and an earthquake recurrence interval of 86 to 600 yrs: based on single-event displacements of 3 to 12 m. The western portion of the Mt. Fyffe segment has a minimum Holocene lateral slip rate of 16 + 5 mm/yr .(southeast side up); the eastern portion has horizontal and vertical slip rates of 4.8+ 2.7 mm/yr and 1.7 + 0.2 mm/yr, respectively (northwest side up). There is no dated evidence for late Quaternary movementon the Seaward segment, and its topographic expression is much more subdued than that of the two western segments. The Jordan Thrust extends northeast from the Hope Fault, west of the Seaward segment. The thrust has horizontal and vertical slip rates of 2.2 + 1.3 mm/yr and 2.1 + 0.5 mm/yr, respectively (northwest side up), and a maximum recurrence interval of 1200 yrs: based on 3 events within the last 3.5 ka.

  • Surface Rupture Database for Seismic Hazard Assessment
    RAPPORT Surface rupture database for Seismic Hazard Assessment 2015 Report of the Kick-Off Meeting of the “SURE Database” Working Group RT/PRP-DGE/2016-00022 Pôle radioprotection, environnement, déchets et crise Service de caractérisation des sites et des aléas naturels ABSTRACT The goal of the fault displacement hazard assessment is to describe and quantify the permanent displacement that can occur during an earthquake at the ground surface. One of the methods to do so is probabilistic (PFDHA: Probabilistic Fault Displacement Hazard Analysis) and is basically based on empirical approaches which allows predicting the possible displacement on the earthquake fault (« on-fault » displacement) and off this major fault on other fault segments (« off-fault » displacement). Predictive relationships (also called “regressions”) were published in the last 15 years (e.g. Youngs et al., 2003; Petersen et al., 2011; Takao et al., 2013) and they are based on data catalogs limited in case numbers and in magnitude ranges. Because there are practical applications of PFDHA in terms of engineering, there is concern in the geologists and engineers communities, for instance in the INQUA and the IAEA-ISSC groups, to improve the methodology. A first and critical step is to build up a community-sourced, worldwide, unified database of surface rupturing earthquakes to include a large number of earthquake cases in various seismotectonic contexts. This is the core task of the SURE (Surface Rupture Earthquake) Working Group which is growing with the support of INQUA and IAEA-ISSC. During the kick-off meeting held in Paris (October 2015) and sponsored by the Institut de Radioprotection et Sûreté Nucléaire (IRSN), earthquake geology experts from the USA, Europe (France, Italy, UK, Germany), Japan, New Zealand, South America (Argentina) formed this group and exchanged their experience in surface rupturing events during 3 days.
