An amendment to the FEIR has been prepared, dated January 2010, and is attached. The amendment describes and analyzes the potential impacts resulting from minor changes to the project description, environment and setting, and/or new information being received, generally described as follows: Modifications to wind turbine layout option #1 (Siemens). Elimination of PG&E reconductoring project from EIR (project near completion). Slight increased size (0.07 acre) of one of two substation options, and increased main transformer size from 40 MVA to 60 MVA. Increased project area from 1,458 to 1,466 acres. New and/or updated reports: blade throw, shadow flicker, low frequency/infrasound noise, and avian mortality. Update and resolution of Travis AFB radar issue related to the Project. Update to Air Quality section of EIR regarding greenhouse gases and global warming. Update to Biological Resources section of EIR regarding California Tiger Salamander and regulations for Bald and Golden Eagles. Other updates regarding County adoption of 2008 General Plan, plans underway for County adoption of updated development standards for wind turbine generators, and recently completed and planned wind energy projects in the vicinity of Montezuma Wind.

  • Species Richness and Endemism in the Native Flora of California
    RESEARCH ARTICLE AMERICAN JOURNAL OF BOTANY Species richness and endemism in the native f ora of California 1 Bruce G. Baldwin 2 , Andrew H. Thornhill , William A. Freyman , David D. Ackerly , Matthew M. Kling , Naia Morueta-Holme , and Brent D. Mishler PREMISE OF THE STUDY: California’s vascular f ora is the most diverse and threatened in temperate North America. Previous studies of spatial patterns of Californian plant diversity have been limited by traditional metrics, non-uniform geographic units, and distributional data derived from f oristic descrip- tions for only a subset of species. METHODS: We revisited patterns of sampling intensity, species richness, and relative endemism in California based on equal-area spatial units, the full vascular f ora, and specimen-based distributional data. We estimated richness, weighted endemism (inverse range-weighting of species), and corrected weighted endemism (weighted endemism corrected for richness), and performed a randomization test for signif cantly high endemism. KEY RESULTS: Possible biases in herbarium data do not obscure patterns of high richness and endemism at the spatial resolution studied. High species richness was sometimes associated with signif cantly high endemism (e.g., Klamath Ranges) but often not. In Stebbins and Major’s (1965) main endemism hotspot, Southwestern California, species richness is high across much of the Peninsular and Transverse ranges but signif cantly high endemism is mostly localized to the Santa Rosa and San Bernardino mountains. In contrast, species richness is low in the Channel Islands, where endemism is signif cantly high, as also found for much of the Death Valley region. CONCLUSIONS: Measures of taxonomic richness, even with greater weighting of range-restricted taxa, are insuf cient for identifying areas of signif cantly high endemism that warrant conservation attention.

  • O-Hydrology and Water Quality
    13 HYDROLOGY AND WATER QUALITY This page intentionally left blank 13 Hydrology and Water Quality 13 HYDROLOGY AND WATER QUALITY This chapter describes the hydrology and water quality setting, summarizes the applicable regulations, evaluates the potential impacts to these resources from the construction and operation of the proposed Montezuma II Wind Energy Project, and identifies mitigation measures to address the impacts found to be potentially significant. 13.1 HYDROLOGY AND WATER QUALITY SETTING The Montezuma II Wind Energy Project covers approximately 2,539 acres in the Montezuma Hills in southwestern Solano County. The Montezuma Hills is an elevated generally treeless area within the Sacramento and San Joaquin River floodplain that consists of rolling hills and experiences dry summers and rainy winters. Rainfall in the area averages 16 to 20 inches per year and less than 0.3 inches of rain in July and August. The area contains intermittent streams and wetlands, but no navigable waters. The Sacramento River borders the Montezuma Hills to the south and east, and the Suisun Marsh borders the area to the west. The southwestern portion of the project area is adjacent to the Suisun Marsh Secondary Management Area and the Sacramento-San Joaquin Delta Secondary Zone. The project area is located in two different water regions. The San Francisco Bay Regional Water Quality Control Board (SFBRWQCB) has jurisdiction over the western portions of the Project and the Central Valley Regional Water Quality Control Board (CVRWQCB) has jurisdiction over the eastern portions. 13.1.1 Drainages The project area is located within the Suisun Bay watershed (Hydrologic Unit Code 18050001), which is characterized by generally treeless rolling hills with higher elevations ranging between 100 and 272 feet above mean sea level (amsl) and near the Sacramento and San Joaquin river delta to the east.

Today, about 80 percent of the marsh plain is privately owned by duck hunting clubs and managed in accordance with conservation agreements. A complex network of sloughs weaves through the Marsh, providing habitat for numerous aquatic species. Together the waterways and marsh plain support a stunning array of species, provide exurban open space, and are increasingly called upon to meet regional conservation objectives.
