Phase I Report
PHASE I REPORT June 2005 Calleguas Creek Watershed Integrated Regional Water Management Plan This Integrated Regional Water Management Plan (IRWMP) is comprised of two volumes: Volume I: Calleguas Creek Watershed Management Plan Phase I Report Volume II: Calleguas Creek Watershed Management Plan Addendum Volume I is provided as a separate document and Volume II is attached. Volume II is intended to bridge the gap between the Calleguas Creek Watershed Management Plan and the requirements for IRWMPs found in the Integrated Regional Water Management (IRWM) Grant Program Guidelines (Guidelines). The two volumes, together, are intended to be a functionally- equivalent IRWMP document. The Guidelines were prepared by the California Department of Water Resources (DWR) and the State Water Resources Control Board (SWRCB) in November 2004 to provide guidance on the process and criteria that DWR and SWRCB will use to evaluate grant applications under the IRWM Grant Program. The Grant program resulted from the passage of Proposition 50, the Water Security, Clean Drinking Water, Coastal and Beach Protection Act of 2002. IRWM is discussed in Chapter 8 of Proposition 50. p:\05\0587108_cmwd_irwmp\attachments\attach3_irwmp\camrosa_only_preface.doc PHASE I REPORT June 2005 Table of Contents Table of Contents........................................................................................................................... i List of Tables............................................................................................................................... -

4.4 Cultural Resources
Trancas Canyon Park EIR Section 4.4 Cultural Resources 4.4 CULTURAL RESOURCES This section analyzes potential impacts to archaeological and historical resources. The discussion summarizes the findings of a Phase I Archaeological Study performed by Historical, Environmental, Archaeological, Research Team (HEART) (HEART, January 2006). The archaeological study included a records search with the South Central Coastal Information Center (SCCIC) and a field survey of the site. The full report is contained in Appendix C. 4.4.1 Archaeological Setting a. Archaeological Overview. At Spanish Contact, the region was occupied by the Native American Indian group known as the Chumash, a diverse population living in settlements along the California coast from Malibu Creek to the southeast, to Estero Bay in the north, including the islands of San Miguel, Santa Rosa, and Santa Cruz, and as far as Tejon Pass, Lake Casitas and the Cuyama River inland (Kroeber 1925, Landberg 1965, Grant 1978, Santa Barbara Museum of Natural History 1986, 1991, Miller 1988 and Gibson 1991). Chumash society became more complex over its last 9,000 years. Regional chronologies were first developed by Wallace (1955) and then Warren (1968). Warren revised Wallace's scheme to include regional variants and traditions enhanced by radiocarbon dates. King (1982) proposed sequences based on changes in ornaments, beads and other artifacts. After A.D. 1000, changes in bead types suggest the development of a highly developed economic system that was observed by early Spanish explorers. Following the 1542 Cabrillo voyage, many small Chumash settlements were abandoned and some of the largest historic towns were founded. -

Roman Stagecoach Inn Museum
NEW AMS DATING SEQUENCES FOR THE CHUMASH VENTURENO EARLY PERIOD: REVISITING THE QUESTION OF ANTIQUITY OF VENTURENO CHUMASH INLAND OCCUPATION DEBORAH V. ROMAN STAGECOACH INN MUSEUM The dating of sites within the Ventureno Chumash interior region has been robust for the Late Period, but less well represented for the Early and Middle Periods. This article presents initial results, including a suite of 20 dates, from three sites (Ven-852, -853, and -1029) in this region that document a well- established occupation sequence including evidence of occupation prior to 9000 cal/bp near the important Late Period ritual site of CA-VEN-632. In the 1980s, amid the boom of housing development in interior Ventura County, a series of academic-affiliated surveys and cultural resource management projects in the Thousand Oaks area revealed a complex of sites that appeared to date to the Early Period, based upon artifact assemblages and bead sequencing evidence (King 1988; Greenwood 1987). Chronologies for the Venura region are partially based upon those created for the nearby Santa Barbara coast, but the two most common chronologies utilized were created by Chester D. King (1990) and Jon Erlandson (2015). King’s (1990) chronology was heavily based upon his bead typology which defined an Early Period from 7000 B.C.-A.D. 300 (1990). Erlandson’s (2015) chronology relied not only on King’s work, but also on more recent radiocarbon dates from the Santa Barbara coastline (1994; 2013). His chronology extended from 8000 RCYBP to 5000 RCYBP. Both chronologies did not utilize calibrated dates; however, in this article, we shall report dates in calibrated form. -
Chapter 8 Natural Resources
Chapter 8 Natural Resources Natural Resources 2040 General Plan 8 NATURAL RESOURCES INTRODUCTION This chapter summarizes the natural resources for the County of Ventura. It is organized into the following sections: . Air Quality (Section 8.1) . Biological Resources and Habitat/Wildlife Corridors (Section 8.2) . Recreation and Open Space (Section 8.3) . Scenic Resources (Section 8.4) . Mineral Resources (Section 8.5) . Energy Resources (Section 8.6) . Cultural, Historical, Paleontological, and Archaeological Resources (Section 8.7) . Appendices (Section 8.8) SECTION 8.1 AIR QUALITY Introduction This section summarizes the existing air quality conditions and regulatory framework within Ventura County. Air quality is described as the concentration of various pollutants in the atmosphere for a specific location or area. Air quality conditions at a particular location are a function of the type and amount of air pollutants emitted into the atmosphere, the size and topography of the regional air basin, and the prevailing weather conditions. Air quality is an important natural resource that influences public health and welfare, the economy, and quality of life. Air pollutants have the potential to adversely impact public health, the production and quality of agricultural crops, native vegetation, visibility, buildings, and other structures and materials. Regarding public health impacts from poor air quality, some people are more sensitive to poor air quality than others. These people include children, the elderly, and persons with asthma and other respiratory conditions. Land uses where these people are likely to be located are defined as sensitive receptors. Sensitive receptors include long-term healthcare facilities, hospitals, rehabilitation centers, retirement homes, convalescent homes, residences, schools, childcare centers, and playgrounds. -
Oxnard GDE Techmemo
Technical Memorandum - DRAFT Assessment of Groundwater Dependent Ecosystems for the Oxnard Subbasin Groundwater Sustainability Plan INTRODUCTION The assessment of groundwater dependent ecosystems (GDEs) is one element of Groundwater Sustainability Plans, required by the California Sustainable Groundwater Management Act (SGMA). The Fox Canyon Groundwater Management Agency’s Technical Advisory Group (TAG) for the development of its Groundwater Sustainability Plans formed an ad hoc committee, comprised TAG members from The Nature Conservancy, United Water Conservation District, and Calleguas Municipal Water District, to support this assessment for the Fox Canyon Groundwater Sustainability Plans. The assessment coincided with development of statewide GDE Guidance by The Nature Conservancy to address GDEs under SGMA (Rohde et al., 2017). Thus, this GDE assessment served dual purposes: 1) to both aid in the development of the guidance framework and 2) serve as a case study of the utility of the guidance framework. This technical memorandum follows seven steps laid out in the GDE Guidance as follows: 1. Identify GDEs 2. Determine Potential Effects on GDEs 3. Consider GDEs when Determining the Basin’s Sustainability Goal 4. Establish Minimum Thresholds 5. Set Measureable Objectives and Five-Year Milestones 6. Describe and Improve Monitoring Network 7. Identify Projects and Management Actions I. Identify GDEs Six groundwater dependent ecosystem (GDEs) units were identified in the Oxnard Groundwater Subbasin: the lower Santa Clara River downstream of the Oxnard Forebay and upstream of the estuary, McGrath Lake, Ormond Beach wetlands, Mugu Lagoon, lower Calleguas Creek, and Revolon Slough GDEs (Figure 1). These six GDE units located in the Oxnard Plain are connected to the shallow semi-perched aquifer. -
