  • Environmental Report MAY 20, 2019 Prepared by Maury Edwards Environmental Chair
    Environmental Report MAY 20, 2019 Prepared by Maury Edwards Environmental Chair Whittier Narrow Dam Repairs The Army Corps of Engineers has expressed concerns that the flood control dam at Whittier Narrows is likely to fail in the event of a severe storm event. This would cause extensive flooding in downstream communities affecting over one million Southern California residents. Although Hacienda Heights would not be directly affected the adjacent communities of Pico Rivera, Santa Fee Springs and Whittier are at risk. Congresswomen Grace Napolitano is requesting FY 20 funding to repair the dam. The final environmental impact statement is expected to be released in May that would allow for the project design and construction starting in 2019 with completion in 2025. L.A. County Board of Supervisors rejects Quemetco plant Expansion The Los Angeles County Board of Supervisors voted on February 19 to oppose the expansion of the Quemtco battery recycling plant located in the City of Industry. The vote was unanimous and a five signature letter will be sent to state and regional environmental agencies requesting that deny Quemetco permission to expand operation by 25 percent. There are too many unanswered questions regarding toxic emissions and release. Hacienda Heights Improvement Association and the His Lai Temple members voiced concerns at the Council meeting. Those attending were and voicing concerns were Scott Martin, President; Board Members Adriana Quinonis; Jennifer Kelly and Lucy Pedregon. Letters from past present Mike Williams and former environmental chairman Joan Licari were also presented. Gina Ooi represented the His Lai Buddhist Temple. The situation with Quemtco is closely being monitored by Congressman Ian Calderon's office and any decisions in regard to Quemtco's expansion plans will be forwarded to all concerned parties.

  • Long-Term Fault Slip Rates, Distributed Deformation Rates, and Forecast Of
    1 Long-term fault slip rates, distributed deformation rates, and forecast of seismicity 2 in the western United States from joint fitting of community geologic, geodetic, 3 and stress-direction datasets 4 Peter Bird 5 Department of Earth and Space Sciences 6 University of California 7 Los Angeles, CA 90095-1567 8 [email protected] 9 Second revision of 2009.07.08 for J. Geophys. Res. (Solid Earth) 10 ABSTRACT. The long-term-average velocity field of the western United States is computed 11 with a kinematic finite-element code. Community datasets include fault traces, geologic offset 12 rates, geodetic velocities, principal stress directions, and Euler poles. There is an irreducible 13 minimum amount of distributed permanent deformation, which accommodates 1/3 of Pacific- 14 North America relative motion in California. Much of this may be due to slip on faults not 15 included in the model. All datasets are fit at a common RMS level of 1.8 datum standard 16 deviations. Experiments with alternate weights, fault sets, and Euler poles define a suite of 17 acceptable community models. In pseudo-prospective tests, fault offset rates are compared to 18 126 additional published rates not used in the computation: 44% are consistent; another 48% 19 have discrepancies under 1 mm/a, and 8% have larger discrepancies. Updated models are then 20 computed. Novel predictions include: dextral slip at 2~3 mm/a in the Brothers fault zone, two 21 alternative solutions for the Mendocino triple junction, slower slip on some trains of the San 22 Andreas fault than in recent hazard models, and clockwise rotation of some domains in the 23 Eastern California shear zone.

  • Facts About the Malibu Lagoon Restoration and Enhancement Plan
    FACTS ABOUT THE MALIBU LAGOON RESTORATION AND ENHANCEMENT PLAN The project is not intended to “clean up” the water quality for recreation, but it will have water quality benefits for the aquatic ecosystem. The lagoon is not healthy • The lagoon is listed on the federal 303(d) list of impaired water bodies, due to excess nutrients and low oxygen levels. • Data collected continuously since 2006 show oxygen levels are frequently below 5 mg per liter, a level that causes stress to aquatic organisms. • Excess nutrients and bacteria attach to fine sediments that settle on the bottom of the channels. • The excess sedimentation is due to poor circulation. • The poor circulation is caused by the pinch points of fill that support the pedestrian bridges, and by the unnatural alignment of the channels, perpendicular to the main lagoon channel. The only way to correct the poor circulation is to remove old fill and reconfigure the channels to a more natural pattern. • The three channels will be reconfigured into a single branched channel that angles towards the ocean. • A single branched channel will cause the water to move faster and will help prevent excess sedimentation. This is similar to the Venturi effect, where the velocity of a fluid increases as the cross section of the tube carrying it decreases. The work will occur only in the western channels and the Adamson boat house channel, not in the main body of the lagoon. • The sand berm beach will not be changed. • The surf break will not be impacted. • The location of the breach and the timing of breaches will not change.

  • 4.9 Utilities
    LSA ASSOCIATES, INC. DRAFT ENVIRONMENTAL IMPACT REPORT SEPTEMBER 2 0 1 6 GENERAL PLAN LAND US E AND URBAN DESIGN E LEMENTS CITY OF LONG BEACH, CALIFORNIA 4.9 UTILITIES 4.9.1 Introduction This section describes the utility providers currently serving the planning area and evaluates the potential impacts of the City of Long Beach (City) General Plan Land Use Element and Urban Design Element (LUE/UDE) project (proposed project) on utility providers. This section is based on multiple data sources, including the Conservation Element (1973) of the City of Long Beach (City) General Plan and the proposed General Plan Land Use and Urban Design Elements (February 2016) (Appendix F), as well as coordination with potentially affected utility providers. Specific references are identified within the subsection for each respective issue. This section addresses the following utility service systems (service providers are noted in parenthesis): Solid Waste (Los Angeles County Sanitation Districts [LACSD]) Wastewater (Los Angeles County Sanitation Districts [LACSD]) Water (Long Beach Water Department [LBWD]) 4.9.2 Methodology After the Notice of Preparation (NOP) was issued, water, wastewater, and solid waste demands were modeled for build out of the proposed project. These calculations were modeled on a citywide basis. Generation rates obtained from applicable service providers were applied to both the existing (2012) land uses and the 2040 land uses proposed as part of the project. The net difference between the 2040 demand for utilities was then compared with the existing demand to generate the project-related increase in demand for water, wastewater treatment, and solid waste facilities.

  • Fire Risk on the Centennial Specific Plan Project Site
    December 6, 2018 Los Angeles County Board of Supervisors 856 Kenneth Hahn Hall of Administration 500 W. Temple Street Los Angeles CA, 90012 Submitted electronically to: [email protected], [email protected], [email protected], [email protected], [email protected], [email protected] CC: [email protected], [email protected] Clarification of Fire Risk on the Centennial Specific Plan Project Site Dear Los Angeles County Board of Supervisors, Thank you very much for the continued opportunity to provide input on the Centennial Specific Plan (“Centennial”). As an organization, the California Native Plant Society (“CNPS”) is very concerned with the potential impacts of Centennial. CNPS has detailed the reasons why we oppose Centennial in numerous comment letters that focus on the project’s unacceptable impacts to irreplaceable grassland habitats, lack of appropriate mitigation, inappropriate use of Cap-and-Trade, and other issues. One issue that continues to be a major concern to CNPS members and the general public is that the Centennial project site is a dangerous place to build a new city for nearly 60,000 people. Chief among our concerns are the facts that project site is designated by CalFire as a High or Very High Fire Severity Zone (see Attachment 1), and that Centennial would be built on/adjacent to California’s two largest earthquake faults, the Garlock and San Andreas (see Attachment 2). The issue of greenlighting large development projects in areas with high fire danger should be a primary concern to decision-makers. The Los Angeles County Board of Supervisors should regard wildfire as a major liability in their pending decision on Centennial.

  • 3.7 Hydrology and Water Quality
    3.7 – HYDROLOGY AND WATER QUALITY 3.7 HYDROLOGY AND WATER QUALITY This section describes the existing setting of the project site and vicinity, identifies associated regulatory requirements, and evaluates potential impacts related to construction and operation of the proposed project. Documents reviewed and incorporated as part of this analysis include the Civil Engineering Initial Study Data (KPFF Consulting Engineers, August 2016, Appendix G), the Sewer Capacity Study (KPFF Consulting Engineers, June 2016, Appendix G), the Geotechnical Engineering Investigation – Proposed Robertson Lane Hotel and Retail Structures, and Subterranean Parking Structure Extension below West Hollywood Park (Geotechnologies Inc, Appendix E). 3.7.1 Environmental Setting Surface Hydrology The City of West Hollywood discharges stormwater via regional underground storm drains into the upper reach of Ballona Creek, a subwatershed of Santa Monica Bay. The Ballona Creek Watershed is approximately 128 square miles in size and is bounded by the Santa Monica Mountains to the north and the Baldwin Hills to the south. The Santa Monica Bay monitoring site for West Hollywood and the other Ballona Creek cities discharging into Santa Monica Bay is at Dockweiler Beach, a site located over 10 miles downstream from the City of West Hollywood. Of the Ballona Creek watershed tributary to this site, 81% is under the jurisdiction of the City of Los Angeles. The other 19% of the watershed area is within the jurisdiction of the cities of Beverly Hills, Culver City, Inglewood, Santa Monica, and West Hollywood; the County of Los Angeles; and Caltrans (City of West Hollywood 2010). Existing stormwater runoff from the project site is conveyed via sheet flow and curb drains to the adjacent streets.
