Cucamonga Creek and Tributaries, San Bernardino and Riverside Counties, California
STATEMENT OF FINDINGS CUCAMONGA CREEK AND TRIBUTARIES SAN BERNARDINO AND RIVERSIDE COUNTIES CALIFORNIA 1. ' As District Engineer, Los Angeles District, U. S. Army Corps of Engineers, I have reviewed and evaluated, in what I believe to be the public interest, the project Tor Cucamonga Creek, West Cucamonga Creek, and Deer Creek channel improvements, from the Sari Gabriel Mountains to Prado Reservoir, San Bernardino and Riverside Counties, California, which is outlined in the project description section of this environmental statement. In evaluating this project, I have considered all project documents, comments by concerned agencies and individuals, and possible alternatives. 2. My staff has (a) compiled an environmental statement that covers the fundamental and basic environmental impacts; (b) computed the cost and economic impacts of the proposed project; (c) considered the project effects on the surrounding community; (d) considered alternatives; and (e) prepared engineering plans for the project. I have reviewed their findings and the comments of Federal, State, local agencies, and interested parties. \ 3. In my evaluation the following points were considered: a. ' Economic considerations. The proposed project will provide flood damage reduction for floods up to standard-project-fiood magnitude to developed areas consisting of valuable residential, commercial, agricultural, and industrial property, important -r-utilities, arterial and interstate highways, an international airport, and transcontinental railroad lines serving the area. b. ‘ Engineering considerations. The project is designed to provide flood protection by providing debris basins and increased channel capacity. The channel is also designed to divert runoff into spreading basins for ground water recharge. c. ' Social well-being considerations. The well-being of the people in the project area will be improved because of flood protection that will reduce the possibility of loss of life, injury', disease, and inconvenience. -

United States Department of Native and Introduced Earthwormsfrom Agriculture Forest Service Selected Chaparral, Woodland, and Pacific Southwest Research Station Riparian Zones in Southern California General Technical Report PSW-GTR-142 Hulton B. Wood Samuel W. James Wood, Hulton B.; James, Samuel W. 1993. Native and introduced earthworms from selected chaparral, woodland, and riparian zones in southern California. Gen. Tech. Rep. PSW-GTR142. Albany, CA: Pacific Southwest Research Station, Forest Service, U.S. Department of Agriculture; 20 p. Relatively little is known about the earthworm fauna of southern California. Some 20 different species of earthworms were collected and identified in a survey of various southern California wildland habitats. The ecology and biology of earthworms are outlined, and the results of the survey are documented. Introduced species belonging to the Lumbricidae family were encountered most often; however, native species, primarily of genera Argilophilus and Diplocardia, are widely, distributed. Several of the natives collected are believed to be new species. Habitats for both the native and introduced species ranged from riparian zones to relatively dry chaparral sites. Preference of earthworms for certain types of plant communities began to emerge even in this somewhat limited survey: oak and grass being the most preferred, and conifers the least. Geographical separation of the two principal native genera occurs at about 34°N. Further research is needed relative to earthworm ecology, impacts on soils, ecosystem dynamics, and fire. An appendix includes all collection records by location, and vegetation and soil type. Retrieval terms: earthworms, Mediterranean ecosystems, southern California, new species, Lumbricidae, Megascolecidae, Acanthodrilinae, Ocnerodrilinae, Sparganophilidae, soil, habitat, chaparral, grassland, woodland, riparian, aquatic The Authors: Hulton B. -
Natural Disasters, Past and Impending, in the Eastern San Gabriel
April 18, 2009 Field Trip #4: Natural Hazards, Past and Impending, in the Eastern San Gabriel Mountains Jonathan A. Nourse Department of Geological Sciences California State Polytechnic University 3801 West Temple Avenue Pomona, CA 91768 Introduction The eastern San Gabriel Mountains present a spectacular outdoor laboratory for studying the causes and consequences of natural hazards that include earthquakes, floods, landslides, and fires. Since 1991 I have utilized the San Antonio Canyon region as a convenient place to educate Cal Poly Pomona students enrolled in my Natural Disasters, Engineering Geology, Structural Geology, Tectonics, Groundwater Geology and Optical Mineralogy courses. The area has also provided world-class field trip sites for the Geological Society of America, the Thomas W. Dibblee Foundation and NAGT. This guidebook includes excerpts from several previous field trip guides for which I have been principle or contributing author (Nourse, et al., 1998; Trent and Nourse, 2001; Trent et al., 2001, Nourse, 2003). The oblique aerial view of Figure 1 highlights the San Gabriel Mountains block, uplifted along the Sierra Madre-Cucamonga frontal thrust system and dissected by left-lateral and right-lateral strike slip faults. Our plan for today is to begin the trip at San Antonio Dam near the intersection of the Cucamonga, San Jose and San Antonio Canyon faults. Working our way up the Mt. Baldy Road, we shall view field evidence of floods, landslides and debris flows that have resulted from interplay between steep topography, severe weather conditions, and major earthquakes. Effects of the devastating fire of 2003 are also prominent. We will discuss impacts of the floods of 1938, 1969, and 2005 on human structures such as dams, roads and buildings. -

Scott Zylstra: “Late Cretaceous Metamorphic and Plutonic of Proterozoic Metasediments of Ontario Ridge, Eastern San Gabriel
LATE CRETACEOUS PLUTONIC AND METAMORPHIC OVERPRINT OF PROTEROZOIC METASEDIMENTS OF ONTARIO RIDGE, EASTERN SAN GABRIEL MOUNTAINS, CALIFORNIA A Thesis Presented to the Faculty of California State Polytechnic University, Pomona In Partial Fulfillment Of the Requirements for the Degree Master of Science In Geological Sciences By Scott B. Zylstra 2017 ACKNOWLEDGEMENTS Many thanks to Drs. Jonathan Nourse and Nicholas Van Buer for countless hours in research, assistance and editing on this project; to Zhan Peng, Anthony LeBeau and Karissa Vermillion for laboratory assistance; to the MENTORES program and the Cal Poly Geology Department for funding; to Joshua Schwartz and Carl Jacobson for valuable insight; and to Jennifer, Gwendolyn and Lydia Jean Zylstra, without whom this work would not be possible (and with whom sometimes has been scarcely possible). iii ABSTRACT The rifting of Rodinia, particularly in western Laurentia, has been a longstanding geologic problem, as Proterozoic rocks in the western U.S. are few and far between. The eastern San Gabriel Mountains contain a large metasedimentary package that has never been dated or thoroughly mapped. We present U-Pb detrital zircon geochronology results of 439 grains dated at CSUN’s LA-ICPMS; also 24 plutonic grains and 19 metamorphic rims of detrital grains analyzed on Stanford’s SHRIMP-RG, along with a detailed map, cross section and stratigraphic column for these Ontario Ridge metasediments. Probability plots of 206Pb/207Pb ages for five quartzite samples show three distinct peaks at ~1200, 1380-1470 and 1740-1780 Ma. Maximum depositional age is constrained by 3 grains between 906 to 934 Ma, which are 11-28% discordant. -
Appendix D Building Descriptions and Climate Zones
Appendix D Building Descriptions and Climate Zones APPENDIX D: Building Descriptions The purpose of the Building Descriptions is to assist the user in selecting an appropriate type of building when using the Air Conditioning estimating tools. The selected building type should be the one that most closely matches the actual project. These summaries provide the user with the inputs for the typical buildings. Minor variations from these inputs will occur based on differences in building vintage and climate zone. The Building Descriptions are referenced from the 2004-2005 Database for Energy Efficiency Resources (DEER) Update Study. It should be noted that the user is required to provide certain inputs for the user’s specific building (e.g. actual conditioned area, city, operating hours, economy cycle, new AC system and new AC system efficiency). The remaining inputs are approximations of the building and are deemed acceptable to the user. If none of the typical building models are determined to be a fair approximation then the user has the option to use the Custom Building approach. The Custom Building option instructs the user how to initiate the Engage Software. The Engage Software is a stand-alone, DOE2 based modeling program.

It is bounded on the west primarily by the existing Cucamonga Wilderness; on the south by National Forest System Road (NFSR) 1N34 Cucamonga Truck Trail; on the east side by private land in Lytle Creek, NFSR 2N57, and 2N58; and on the north by NFSR 3N06. Cucamonga B is separated from the Cucamonga C Inventoried Roadless Area by Day Canyon. This area is comprised of the upper Lytle Creek and Cucamonga Creek watersheds. It lies west of the rural community of Lytle Creek, with the more larger, more urbanized Rancho Cucamonga and Upland communities located in the valley about one mile south. • Geography, topography and vegetation (including the ecosystem type(s) o Cucamonga B contains steep, heavily dissected ridges with dense chaparral ecosystems and some riparian areas in the lower elevations and mixed conifer in the upper elevations. Elevations range from about 3,000 to 7,800 feet with an aspect that varies. Topography is steep from Lytle Creek west up towards the boundary with the Angeles National Forest. o A few minor, intermittent streams are present along with some of the perennial North, Middle and South Forks of Lytle Creek. -
How Sensitive Are Spatial Estimates of Wilderness Recreation Values to Information About Hiking Destinations? José J
Journal of Forest Economics, 2020, 35: 19–41 How Sensitive are Spatial Estimates of Wilderness Recreation Values to Information about Hiking Destinations? José J. Sánchez1 , Kenneth Baerenklau2 and Armando González-Cabán1* 1USDA Forest Service, Pacifc Southwest Research Station, 4955 Canyon Crest Drive, Riverside, CA 92507, USA 2School of Public Policy, University of California, Riverside, Riverside, CA 92521, USA ABSTRACT This study uses individual survey data to investigate the impact of information about hiking destinations on estimated wilderness values in a spatial context. The data is derived from a revealed preference survey of backcountry visitors who responded to ques- tions about their recreation behavior in the San Jacinto Wilderness of southern California. Two GIS data layers are developed showing spatial representations of non-market values derived from a Kuhn- Tucker demand model, with and without destination information. Each pixel in each data layer contains an estimate of the recreation value at that location. The destination data provides more detailed information on recreation behavior that can be used to more accu- rately allocate the landscape values. Results show that including destination information produces signifcantly greater heterogeneity in parcel value estimates for large areas of the wilderness.
