The Flood Control Act of 22 June 1936, as amended 28 June 1938, authoriaed a flood-control plan of improvement for protection of rnstropolitan areas in Los Angeles County; Santa Fe Ilam and Flood-Control Rewrvoir is part of this authorized plan; it was constructed by the Corps of Engineers, Los Angeles Mstrict, between August 194l and January 1949. 1.02. Project location. me Santa Fe flood control basin is located on the outwash area of the San Gabriel Mver in the eastern part of Los Angeles County, Cabifornia, about 5 miles downstream from the mouth of San Gabriel canyon, about 15 miles northeasterly from Los Angeles and 3 miles southwesterly from the town of Armsa. It is bounded on the north by the Atchison, Topelm and Santa Fe Raflway, on the west by the suburban development of Duarte, and on the east by the industrial plants, homes, highways and orchards of the area between Azuser. and Baldwin Park. The location of the project is shown in exhibit B and drawing file, No. 483/2, exhibit F. 1.03. Foundation of Santa Fe Dam site. The formation at this site is Recent alluvium consisting primarily of gravel and boulders up to-4 feet in diameter, together with considerable quantities of loose sand and very little clay or silt. The records of deep water wells drilled in the vicinity indfcate that this gravel and boulder type of materid. extends from the surface to depths

  • Chapter 3.10 Water Quality and Hydrology
    CHAPTER 3.10 WATER QUALITY AND HYDROLOGY 3.10 WATER QUALITY AND HYDROLOGY This section presents a discussion of the existing hydrology, hydrological conditions, and drainage patterns in the project area and vicinity as well as a discussion of potential impacts of the Proposed Project on hydrology and drainage. The section begins with a description of the existing environment, followed by a discussion of relevant federal, State and local laws and regulations. Where potential environmental impacts are identified, a mitigation program is developed to reduce these impacts to the extent feasible. Finally, residual impacts and cumulative impacts are discussed. Information in this section of the EIR evaluates written comments on the NOP received by the Los Angeles Regional Water Quality Control Board (April 4, 2014); Los Angeles County Department of Public Works (April 15, 2014); and the Main San Gabriel Basin Watermaster (April 7, 2014). A copy of each letter can be found in Appendix B of this EIR. 3.10.1 EXISTING ENVIRONMENT Surface Water The City of Irwindale is located in the Los Angeles-San Gabriel Hydrologic Unit. The San Gabriel River watershed is the main surface water body in this Unit, covering approximately 689 square miles. The San Gabriel River flows from northeast to southwest through the City, generally flowing parallel to Interstate 605 (I-605). The San Gabriel River headwaters are located in the San Gabriel Mountains to the north. Most of the stormwater runoff in the region is directed to the San Gabriel River. The upper two reaches of the San Gabriel River watershed consist largely of undisturbed riparian and woodland habitats.

    California Partners in Flight Coastal Shrub and Chaparral Bird Conservation Plan Coastal Cactus Wren ( Campylorhynchus brunneicapillus ) Photo by James Gallagher, Sea and Sage Audubon Prepared by: Christopher W. Solek ([email protected]) University of California, Berkeley Berkeley, CA 94720 Dr. Laszlo J. Szijj ([email protected]) Biological Sciences Department California State Polytechnic University, Pomona RECOMMENDED CITATION: Solek, C. and L. Szijj. 2004. Cactus Wren ( Campylorhynchus brunneicapillus ). In The Coastal Scrub and Chaparral Bird Conservation Plan: a strategy for protecting and managing coastal scrub and chaparral habitats and associated birds in California. California Partners in Flight. http://www.prbo.org/calpif/htmldocs/scrub.html Range Map: ACTION PLAN SUMMARY Species: Coastal Cactus Wren ( Campylorhynchus brunneicapillus) Status: A coastal population from San Diego County was nominated for subspecies status as C. b. sandiegensis in 1990 and subsequently proposed for Federal Threatened status in 1991. Since this subspecies designation was not recognized by the American Ornithologists’ Union Committee on Classification and Nomenclature, the San Diego population was declined for Federal Threatened listing by the U.S. Fish and Wildlife Service in 1994. Habitat Needs: Coastal sage scrub with patches of tall Opuntia cacti for nesting and breeding. This coastal population appears to nest almost exclusively in Opuntia cacti of at least 1 m in height. Protection of habitat areas with this vegetation type and structure should be a high priority. Concerns: Habitat loss, degradation, and fragmentation are the most critical management issues facing this species. Although the species appears capable of sustaining breeding populations in small, fragmented areas containing suitable habitat, isolation of coastal populations due to urban fragmentation may be promoting loss of genetic variation within these smaller populations and compromise long-term metapopulation viability.

  • Santa Fe Dam Park Lake Tmdls
    U.S. Environmental Protection Agency Los Angeles Area Lakes TMDLs March 2012 Section 11 Santa Fe Dam Park Lake TMDLs Santa Fe Dam Park Lake TMDLs March 2012 11 Santa Fe Dam Park Lake TMDLs Santa Fe Dam Park Lake (#CAL4053100020000303202907) is listed as impaired by copper, lead, and pH SWRCB, 2010). This section of the TMDL report describes the pH impairment and the TMDLs developed to maintain existing water quality (Section 11.2). Nutrient TMDLs are identified here based on existing conditions since nitrogen and phosphorus levels are achieving the chlorophyll a target level. Comparison of metals data to their associated hardness-dependent water quality objectives indicates that copper and lead are currently achieving numeric targets at Santa Fe Dam Park Lake; therefore, TMDLs are not included for these pollutants. Analyses are presented below for lead (Section 11.3) and copper (Section 11.4). 11.1 ENVIRONMENTAL SETTING Santa Fe Dam Park Lake is located in the San Gabriel River Basin (HUC 18070106) in the Santa Fe Flood Control Basin (Figure 11-1; Figure 11-2). This waterbody was constructed in 1978 by the US Army Corps of Engineers. According to the Los Angeles County Department of Public Works (personal communication Arthur Gotingco, July 13, 2009, County of Los Angeles Dept. of Public Works) and the superintendent of Santa Fe Dam Park Lake, no flood waters are diverted to the park lake (flood water that is diverted from the San Gabriel River enters the spreading grounds and does not reach the lake). In addition, there is no outlet from the lake (personal communication, Chris Graham, County of Los Angeles, March 31, 2010).
