GENERAL INFORMATION Purpose of 5-Year Reviews: The U.S. Fish and Wildlife Service (Service) is required by section 4(c)(2) of the Endangered Species Act (Act) to conduct a status review of each listed species at least once every 5 years. The purpose of a 5-year review is to evaluate whether or not the species’ status has changed since it was listed. Based on the 5-year review, we recommend whether the species should be removed from the list of endangered and threatened species, be changed in status from endangered to threatened, or be changed in status from threatened to endangered. Our original listing of a species as endangered or threatened is based on the existence of threats attributable to one or more of the five threat factors described in section 4(a)(1) of the Act, and we must consider these same five factors in any subsequent consideration of reclassification or delisting of a species. In the 5-year review, we consider the best available scientific and commercial data on the species, and focus on new information available since the species was listed or last reviewed. If we recommend a change in listing status based on the results of the 5-year review, we must propose to do so through a separate rule-making process defined in the Act that includes public review and comment.

  • Watershed Summaries
    Appendix A: Watershed Summaries Preface California’s watersheds supply water for drinking, recreation, industry, and farming and at the same time provide critical habitat for a wide variety of animal species. Conceptually, a watershed is any sloping surface that sheds water, such as a creek, lake, slough or estuary. In southern California, rapid population growth in watersheds has led to increased conflict between human users of natural resources, dramatic loss of native diversity, and a general decline in the health of ecosystems. California ranks second in the country in the number of listed endangered and threatened aquatic species. This Appendix is a “working” database that can be supplemented in the future. It provides a brief overview of information on the major hydrological units of the South Coast, and draws from the following primary sources: • The California Rivers Assessment (CARA) database (http://www.ice.ucdavis.edu/newcara) provides information on large-scale watershed and river basin statistics; • Information on the creeks and watersheds for the ESU of the endangered southern steelhead trout from the National Marine Fisheries Service (http://swr.ucsd.edu/hcd/SoCalDistrib.htm); • Watershed Plans from the Regional Water Quality Control Boards (RWQCB) that provide summaries of existing hydrological units for each subregion of the south coast (http://www.swrcb.ca.gov/rwqcbs/index.html); • General information on the ecology of the rivers and watersheds of the south coast described in California’s Rivers and Streams: Working

  • Los Angeles County
    Steelhead/rainbow trout resources of Los Angeles County Arroyo Sequit Arroyo Sequit consists of about 3.3 stream miles. The arroyo is formed by the confluence of the East and West forks, from where it flows south to enter the Pacific Ocean east of Sequit Point. As part of a survey of 32 southern coastal watersheds, Arroyo Sequit was surveyed in 1979. The O. mykiss sampled were between about two and 6.5 inches in length. The survey report states, “Historically, small steelhead runs have been reported in this area” (DFG 1980). It also recommends, “…future upstream water demands and construction should be reviewed to insure that riparian and aquatic habitats are maintained” (DFG 1980). Arroyo Sequit was surveyed in 1989-1990 as part of a study of six streams originating in the Santa Monta Mountains. The resulting report indicates the presence of steelhead and states, “Low streamflows are presently limiting fish habitat, particularly adult habitat, and potential fish passage problems exist…” (Keegan 1990a, p. 3-4). Staff from DFG surveyed Arroyo Sequit in 1993 and captured O. mykiss, taking scale and fin samples for analysis. The individuals ranged in length between about 7.7 and 11.6 inches (DFG 1993). As reported in a distribution study, a 15-17 inch trout was observed in March 2000 in Arroyo Sequit (Dagit 2005). Staff from NMFS surveyed Arroyo Sequit in 2002 as part of a study of steelhead distribution. An adult steelhead was observed during sampling (NMFS 2002a). Additional documentation of steelhead using the creek between 2000-2007 was provided by Dagit et al.

  • Reservoir Sedimentation and Water Supply Reliability By: Aubrey Mescher, MESM Ms
    Reservoir Sedimentation and Water Supply Reliability By: Aubrey Mescher, MESM Ms. Mescher is a water resources specialist at Aspen’s Agoura Hills headquarters office. Our reservoirs are filling with sediment. That’s the same as dirt. Mud, muck, silt. Rocks, gravel, even boulders. All of this stuff where there’s supposed to be just water. Water for drinking, irrigation, recreation, commercial and industrial uses, flood control, and groundwater recharge. This isn’t a new issue. Actually, reservoirs are assumed to have a finite lifetime, limited by loss of function due to sedimentation. But reservoirs are filling with sediment far more quickly than anticipated, and important water supply and flood control facilities are not only being rendered useless before their time, but in doing so they are simultaneously introducing new issues with public safety and water supply reliability. What is sedimentation? Sedimentation is a natural process that occurs when soil particles suspended in water settle out of the main water column to the bottom. Sediment content in a waterway is higher during and after storm events, when rates of flow and erosion are higher, and lower during dry months, when these rates tend to be lower. Under natural conditions, unconstrained by a dam, the quantity of water and sediment in a waterway is generally balanced, as the ground surface and riverbed erode into the waterway, and sediment is deposited in downstream areas, where it provides habitat and replenishes riverbanks and beaches. But when a dam is constructed in a waterway, it traps the flow of both water and sediment. The sediment gradually accumulates behind the dam, larger particles such as rocks and gravel settling to the reservoir floor while the spaces in between fill with finer material such as silt and mud.

The new law, commonly referred to as AB162, mandates that the Land Use Element identify flood-prone areas as mapped by either the Federal Emergency Management Agency (FEMA) or the State Department of Water Resources. To prepare and mitigate hazards from flooding, the City of Azusa participates in the National Flood Insurance Program. Flood Insurance Rate Maps, which are prepared by FEMA, identify potential flood zones. The Community Safety Element addresses this issue in detail.

  • 6.0 Other Ceqa Discussions 6.1 Growth
    Target Store Redevelopment Project 6.0 Other CEQA Discussions Draft EIR 6.0 OTHER CEQA DISCUSSIONS 6.1 GROWTH-INDUCING IMPACTS Section 15126.2(d) of the CEQA Guidelines states that the assessment of growth-inducing impacts in the EIR must describe the “ways in which the proposed project could foster economic or population growth, or the construction of additional housing, either directly or indirectly, in the surrounding environment.” The project site is within a redevelopment area, which seeks to attract private investment into an economically depressed community. The proposed project would not induce growth, but would seek to stimulate the economy of downtown Azusa. The proposed project would bring growth to the area by providing 129 net new jobs. The new jobs would be available to the local community and the project applicant would be encouraged to hire locally. With the addition of jobs, the proposed project would foster economic growth in the project area. The proposed project would not create more jobs than the adopted Southern California Association of Government (SCAG) forecast for the San Gabriel Valley Cities Council of Government (SGVCCG) Subregion. The new jobs and retail use would help to revitalize the downtown Azusa area. Thus, the proposed project would meet the goals of the Merged Project Area Redevelopment Plan by stimulating economic growth in the area. The proposed project does not include the construction of housing. In addition, the operation of the proposed project is not expected to induce population growth in the project area because similar uses currently exist on the project site. Therefore, the proposed project is not anticipated to increase population growth either directly or indirectly.

  • City of Azusa Local Hazard Mitigation Plan October 2018
    City of Azusa Local Hazard Mitigation Plan October 2018 Executive Summary The City of Azusa prepared this Local Hazard Mitigation Plan (LHMP) to guide hazard mitigation planning to better protect the people and property of the City from the effects of natural disasters and hazard events. This plan demonstrates the community’s commitment to reducing risks from hazards and serves as a tool to help decision makers direct mitigation activities and resources. This plan was also developed in order for the City to be eligible for certain federal disaster assistance, specifically, the Federal Emergency Management Agency’s (FEMA) Hazard Mitigation Grant Program (HMGP), Pre-Disaster Mitigation (PDM) Program, and the Flood Mitigation Assistance (FMA) Program. Each year in the United States, natural disasters take the lives of hundreds of people and injure thousands more. Nationwide, taxpayers pay billions of dollars annually to help communities, organizations, businesses, and individuals recover from disasters. These monies only partially reflect the true cost of disasters, because additional expenses to insurance companies and nongovernmental organizations are not reimbursed by tax dollars. Many natural disasters are predictable, and much of the damage caused by these events can be alleviated or even eliminated. The purpose of hazard mitigation is to reduce or eliminate long- term risk to people and property from hazards LHMP Plan Development Process Hazard mitigation planning is the process through which hazards that threaten communities are identified, likely impacts determined, mitigation goals set, and appropriate mitigation strategies determined, prioritized, and implemented. This plan documents the hazard mitigation planning process and identifies relevant hazards and vulnerabilities and strategies the City will use to decrease vulnerability and increase resiliency and sustainability in the community.
