The Notice of Intent indicates that the City proposes the adoption of a Mitigated Negative Declaration for this project. The project area begins at the intersection of Atlantic and District Boulevards, which is adjacent to the north side of Maywood Elementary School, and extends northeast across the Los Angeles River. Based on the location and size of the proposed development, it is our opinion that significant environmental impacts on the surrounding community (traffic, noise, air, pollution, etc.) will occur. Since the project will likely have a significant impact on Maywood Elementary School, mitigation measures designed to help reduce or eliminate such impacts are included with this response.

El Molino Avenue, Suite 310 Pasadena, CA 91101 SUBJECT: Atlantic Blvd. Bridge over the Los Angeles River — Initial Study and Mitigated Negative Declaration —Property at 5122 S. Atlantic Blvd. Dear Ms. Papirian: The City of Vernon has received your letter dated September 20, 2006 and provides the following clarifications that should eliminate the concerns of your client: 1. The City of Vernon will seek a dedication that is only 8 feet deep along the frontage on Atlantic Blvd only. No dedication will be required on District Blvd. The dedication will not reduce the size of the property by a significant amount and will not impact the existing structures or their use. The Building Code regulations will remain unchanged. 2. The existing driveway access to the property from Atlantic Blvd. is accomplished from an eleven foot wide lane and angling across a narrow merge lane. If the proposed widening is constructed the street will be widened to create a fourteen foot wide travel lane that can be used to directly access the property from Atlantic Blvd. The corner curb will remain in the same location and the driveway access will be in approximately the same location but parallel to the Atlantic Blvd. lane lines. This configuration will permit direct access from and to the adjacent lane in Atlantic Blvd. that will have turning movements with larger turning radii for vehicles, higher visibility and increased safety. The City of Vernon will seek the dedication of the 8 feet of frontage along Atlantic Blvd. in the future using the State of California acquisition procedures. The City will appraise the value of the dedication and negotiate to acquire the dedication at fair market value.

Crystal Investments Property Site affected: 5122 So. Atlantic, Venon, CA 90040 Dear Sir or Madam: This letter lists the concern of the property owner, to whom your agency has requested a negative declaration of its property located at the above -referenced address. The property is currently used as a fuel depot and has been so used for over forty years. The proposed negative declaration shall grossly affect the owner's use of said property and constitutes a taking violative of the United States Constitution and of the Constitution of the State of California, by the following ways: Large reduction in lot size; 2. Adverse impact on use of existing structures, such that they cannot be used for their purpose. Adverse effect on Code restrictions on sizing and location of structures because of the proposed displacement of property lines. 4. There currently is a railroad track with and easement running on the opposite side of the property which runs the length of the property for a width of 15 feet. 5. The entrance and exist of the building facing Atlantic Boulevard shall be right on the proposed property line, thus making it unsafe of entrance and exit onto the property.. Page 1 of 2 Tel: 626.796.6258 Fax: 626.795.6138 - • The proposed negative declaration would carve an L shaped area approximately 8 feet wide along the a majority of the affected property, which would in essence render the property unusable for its intended purpose. Attached you will find a copy of an areal photograph of the affected property with a highlighted L shape identifying the proposed negative declaration. Counterproposal: It is requested that the actual negative declaration be made for a lesser width such as 4 feet and that this property be excused from Code restrictions proscribing building restrictions of set backs and other issues as an additional measure to permit the property owners in not being penalized twice because of the proposed negative declaration, in perpetuity. Additionally, that the property owner be compensated the fair market value of the proposed negative declaration, with due consideration given to the impact and diminution in use of the.property. This letter is submitted for consideration to all entities listed on the Initial Study and Mitigated Negative Declaration. Thank you. Very truly, Ani Pa irian, Es .

PROJECT NEED Implementation of the proposed project would improve capacity and operational functions along Atlantic Boulevard. B. PROJECT DESCRIPTION To enhance the safety of Atlantic Blvd. over the Los Angeles River and improve the intersection performance at District Blvd., the City of Vernon proposes to widen Atlantic Blvd. north of the Los Angeles River to 800 feet south of the intersection with District Blvd. The proposed project is located approximately 0.25 miles (mi) southwest of the Long Beach Freeway (1-710) in the City of Vernon. The bridge length is approximately 0.08 mi. The site location map is presented in Figure 1 on page 1-8. The bridge connects the portion of the intensely industrial City of Vernon south of the Los Angeles River with the 1-710 Freeway, a major truck route from the ports of Los Angeles and Long Beach. The route is also used by the mostly residential City of Maywood to connect to the 1-710 and I-5 freeways. The bridge provides a six -lane elevated crossing over the Los Angeles River. At this location, the river is completely channelized with concrete lining and a low flow waterway. Railroad tracks cross the approaches on both river banks. As both railroad tracks are siding tracks with no high speed through trains, the crossings are at grade, and traffic is controlled by crossing lights, not crossing gates. On the north river bank, Los Angeles Department of Water and Power (LADWP) electric transmission towers are parallel to the River. A bike path begins at Atlantic Blvd. and is along the south river bank to the east. The project involves widening Atlantic Boulevard for approximately 1,300 linear feet to provide traffic shoulders, standard sidewalks and a right turn lane over the Atlantic Blvd. Bridge. The proposed roadway configuration includes six 11-foot through traffic lanes, one 11-foot right turn lane, 4-foot minimum shoulders and a median varying from 3 feet to 8 feet at District Blvd. To accomplish the bridge widening, the pier wall supports will be widened approximately 16 feet to the west and 19 feet to the east. In addition, debris nosing walls will be installed upstream of the bridge, extending approximately 30 feet upriver. Construction of the pier widening and debris wall will include drilling piles in the river. PROPOSED ATLANTIC BLVD. BRIDGE WIDENING: INTITIAL STUDY/NEGATIVE DECLARATION The bridge widening will require additional easement right-of-way (ROW) from the Los Angeles County Flood Control District within the Los Angeles River. ROW will also be required from the LA Junction railroad and the Los Angeles Department of Water and Power. The roadway to the south of District Blvd. will be widened to the east in order to match the bridge width. At the south end of the bridge, additional ROW easements will be taken at two properties on the east side of Atlantic at District Blvd. The existing curb line will remain, with no modifications, on the west side of Atlantic Blvd, south of District Blvd, near the existing elementary school. To accomplish this bridge widening, new piles will be drilled in -stream on both sides of the bridge to support the additional lanes. Currently, there are six bents in -stream supporting the bridge. These bents comprise a series of piles and are aligned parallel to the channel flow and at an angle to the centerline of the bridge and roadway spanning the channel. To each of these piers piles will be added to the west and east ends. In addition to the bridge foundation, debris walls will be added on the upstream side with their own foundations. Construction will initially consist of pile installation and excavating and drilling of piles to support the bridge. Small diameter, cast -in -drilled -hole (CIDH) concrete piles will be used for debris walls in -stream and large -diameter CIDH piles will be used at the bridge piers. The CIDH piles, pile caps, and deck widening will require poured concrete in steel or wooden forms. In this manner, no temporary structures will be constructed on the bottom of the channel. Bridge construction will require heavy equipment, such as a drill rig and crane for lifting the deck beams. The Los Angeles Department of Water and Power maintenance roads may be used as staging areas for construction material and equipment. The roadway portion of the bridge will involve typical paving construction equipment. C. CALIFORNIA ENVIRONMENTAL QUALITY ACT (CEQA) Pursuant to the California Environmental Quality Act of 1970 (CEQA), as amended, an Initial Study (IS) for the proposed project has been conducted to identify any significant environmental effects and to determine whether an Environmental Impact Report (EIR) or Negative Declaration (ND) should be prepared. The results of the IS indicate that, with the implementation of mitigation measures for potential effects on cultural resources, geology and soils, hazards and hazardous materials, and hydrology and water quality the project would have no impacts, or less than significant impacts, in all environmental resource areas. Hence, a Mitigated Negative Declaration (MND) is the appropriate CEQA document for this proposed project and further detailed analysis is not required. D. PROPOSED MITIGATION MEASURES The project could have potentially significant adverse impacts on cultural resources, geology and soils, hazards and hazardous materials, hydrology and water quality, public services and transportation/traffic. The following mitigation measures will be implemented to reduce these potential impacts to a less than significant level: 1-2 PROPOSED ATLANTIC BLVD. BRIDGE WIDENING: INTITIAL STUDY/NEGATIVE DECLARATION Cultural Resources: In accordance with Section 106 of the NHPA, an archeological survey was completed for the project site (March 1, 2005) to identify historic properties that may lie within the study area. The survey area included the proposed project construction footprint, easements, and staging areas (see Appendix A: Section 106 Historic Property Survey Report — Attachment II: Archeological Survey Report). The survey found no archeological resources eligible for listing on the National Register of Historic Places (NRHP). And, as defined in Section 15064.5 of CEQA, the Project would result in no impact to cultural resources because under (b) the Project would not cause a substantial adverse change in the significance of an archeological resource. Similarly, the project would have under (c) no impact on human remains: Because no human remains have been reported in the project area, the Project would not likely disturb human remains, including those interred outside of formal cemeteries. Although, the archaeological records search, supplemental archival research, and field survey suggest that no known archeological exist with the project area. However, due to the proximity of the Los Angeles River and former historical built environment features, buried archeological features and deposits may exist within the project area. These could include, but are not limited to, Native American archaeological remains such as stone tool scatters, habitation artifacts of bone and vegetal composition, and isolated burials. Historical archaeological deposits could consist of privy pits, refuse deposits, and subsurface remnants of the earlier built environment. In case buried archeological features and deposits are found within the project area, the following mitigation measure shall be implemented to reduce potential impacts to below the level of significance: CR-1: Ground disturbing activities that take place in native soils outside of the channelized portion of the Project Area (i.e. on the river terrace) shall be monitored at the discretion of a qualified archaeologist. Ground disturbing and excavation activities that necessitate monitoring include the following: a) removal of the built environment directly related to exposing native soils, b) digging of any kind, including footings, and c) soil spreading. Pile driving does not necessitate monitoring as it precludes the discovery of cultural resources. The project archeologist shall attend all preconstruction meetings and shall have the authority to temporarily halt or redirect construction equipment if cultural materials are encountered so that they may be documented and recovered as appropriate. In accordance with the California Health and Safety Code (Public Resources Code 7050.5), and California Environmental Quality Act (regarding human remains); in the event human remains are encountered during the construction activities, all work in that area shall cease. The Los Angeles County Coroner shall be notified immediately of the remains, who shall determine whether they are of historic or recent demise. PRC 7050.5 requires the county coroner to contact the Native American Heritage Commission within 24 hours if the coroner determines that the remains are of Native American origin. Implementation of CEQA, PRC 7050.5 and PRC 5097.98 and coordination with the Native American most likely descendants (MLD) to recover, treat and re -inter human remains and associated grave goods in a respectful manner can mitigate significant impacts of these remains to a less than significant level. Geology and Soils: The project site is within an area of historic occurrence of liquefaction (see Appendix A: Preliminary Geotechnical Memorandum). Due to the generally shallow depth of historically high 1-3 PROPOSED ATLANTIC BLVD. BRIDGE WIDENING: INTITIAL STUDY/NEGATIVE DECLARATION groundwater and the generally unconsolidated nature of the Late Holocene deposits, the potential for soil liquefaction during an earthquake is considered moderate to high at the site. The California Geological Survey (CDMG, 1998) has mapped the site as being within a Liquefaction Hazard Zone. The following mitigation measure shall be implemented to reduce potential liquefaction impacts to below the level of significance: GS -1: Prior to design, a final foundation investigation should be performed to determine the final pile type and depth. The investigation findings will be submitted to the City of Vernon Community Services Department — Public Works Division for review and approval. Hazards and Hazardous Materials: The proposed project involves the relocation of utility lines and minimal demolition of curbs and sidewalks. No habitable structures will be constructed. However, heavy equipment, such as cranes and drilling rigs, will be used that could result in the combustion of flammable fuels. The likelihood of such an occurrence is minimal. Additionally, there is the potential for unforeseen collapse of the piles that could result in inadvertent discharge of concrete into the water. To reduce the risk of such an occurrence, the following mitigation measure is recommended: HHM -1: The final design plans and specifications shall require that the contractor for construction of the improvements prepare and submit to the City of Vernon Environmental Health Department for approval a Hazardous Materials Spill Prevention and Containment Plan. Hydrology and Water Quality: The proposed project involves the installation of piles within the Los Angeles River. Drilling the piles into the River bottom would result in the displacement of soil and increase turbidity in the water. Additionally, the use of pile drivers/drill rig and other diesel powered heavy equipment would result in residual release of hydrocarbons into the water. The project itself does not involve the direct or immediate discharge into the River of any substance, manufacturing byproduct or waste discharge. However, the potential for unforeseen collapse of the piles could result in inadvertent discharge of concrete into the water. To reduce the risk of such an occurrence and the potential of violating water quality standards, the following mitigation measure is recommended: HWQ -1: The final design plans and specifications shall require that the contractor prepare and submit to City of Vernon Environmental Health Department for approval a Hazardous Materials Spill Prevention and Containment Plan. Public Services: The proposed project would not result in the demand for new or altered local school facilities or services. No significant impacts will occur. However, in accordance to comments received from the Los Angeles Unified School District, the following mitigation measures are recommended to provide for public and school safety during construction. PS-1: The final design plans and specifications shall require that the contractor maintain unrestricted access for school buses during construction. PS-2: The final design plans and specifications shall require that the contractor not endanger passenger safety or delay student drop-off or pickup due to changes in traffic patterns, lane adjustments, altered bus stops, or traffic lights. PS-3: The final design plans and specifications shall require that the contractor maintain safe convenient pedestrian routes to LAUSD schools. 1-4 PROPOSED ATLANTIC BLVD. BRIDGE WIDENING: INTITIAL STUDY/NEGATIVE DECLARATION PS-4: The final design plans and specifications shall require that the contractor install appropriate traffic controls to ensure pedestrian safety and vehicular safety during construction. PS-5: The final design plans and specifications shall require that the contractor does not haul construction equipment or materials past affected school sites, during school arrival and dismissal times. PS-6: The final design plans and specifications shall require that the contractor does not stage or park construction -related vehicles, including worker -transport vehicles, adjacent to school sites. PS-7: The final design plans and specifications shall require that the contractor install barriers and/or fencing to secure to secure construction equipment and site to prevent trespassing, vandalism, and short-cut attractions. PS-8: The final design plans and specifications shall require that the contractor provide security patrols to minimize trespassing, vandalism, and short-cut attractions. Transportation/Traffic: The widening of the bridge will require the widening of Atlantic Blvd. and will require the reconstruction of the driveway access to private property at the northeast corner of Atlantic Blvd. and District Blvd. The emergency access will be maintained at all times since this property houses a fuel distribution facility. TT-1: The final design plans and specifications shall provide for reconstruction of the existing driveway access to Atlantic Blvd. for the property at the northeast corner of Atlantic Blvd. and District Blvd. Emergency access will be maintained at all times to the fuel distribution facility on the site. E. CONCLUSIONS Based on the Initial Study, the proposed project and construction activities along with the implementation of mitigation measures would not have a significant effect on the environment. A Mitigated Negative Declaration is the appropriate environmental document per the requirements of CEQA. F. DOCUMENT PREPARATION This Initial Study (IS) and Mitigated Negative Declaration (MND) was prepared by URS Corporation (URS) under contract to the City of Vernon's Public Works Division. Direction was provided by Samuel Kevin Wilson, Director of Community Services and Water for the City. 1-5 PROPOSED ATLANTIC BLVD. BRIDGE WIDENING: INTITIAL STUDY/NEGATIVE DECLARATION 1.0 PURPOSE AND NEED 1.1 INTRODUCTION This environmental document is an Initial Study (IS) and Mitigated Negative Declaration (MND). An MND is a written statement by the Lead Agency briefly describing the reasons that a proposed action which is not otherwise exempt from the California Environmental Quality Act (CEQA) of 1970, as amended, would have a less than significant impact on the environment and, therefore, does not require the preparation of an EIR. The City of Vernon City Council is the Lead Agency for the project under CEQA. Negative Declarations (NDs) which recommend the implementation of mitigation measures to reduce potentially significant environmental impacts to a less than significant level are termed Mitigated Negative Declarations (MNDs). This document has been prepared in accordance with the California CEQA Guidelines, with Title 14 of the California Administrative Code, as revised. 1.2 PROJECT TITLE Proposed Atlantic Boulevard Bridge Widening Over the Los Angeles River. 1.3 LEAD AGENCY City Council City of Vernon 4305 Santa Fe Ave. Vernon, California 90058 1.4 CONTACT PERSON Samuel Kevin Wilson, Director of Community Services and Water City of Vernon 4305 Santa Fe Ave. Vernon, California 90058 1.5 PROJECT LOCATION Atlantic Boulevard between Bandini Blvd. and Slauson Avenue. 1.6 PROJECT SPONSOR'S CONTACT NAME AND ADDRESS Samuel Kevin Wilson, Director of Community Services and Water City of Vernon 4305 Santa Fe Ave. Vernon, California 90058 1-6 PROPOSED ATLANTIC BLVD. BRIDGE WIDENING: INTITIAL STUDY/NEGATIVE DECLARATION 1.7 GENERAL PLAN DESIGNATION General Industrial 1.8 ZONING General Industrial (M) and Heavy Industry/Warehousing Transportation Related (1\4-2) 1.9 PROJECT LOCATION AND DESCRIPTION Location: The proposed project is located within Township 2 South, Range 12 West, Section 18 as depicted on the South Gate, California USGS 7.5 Minute Series Topographic Quadrangle Map. The project area begins north of District Boulevard and extends north-eastward along Atlantic Boulevard, crossing over the Los Angeles River and ends near the railroad tracks on the north side of the river. The site is regionally located south/southwest of the Long Beach Freeway (I710) and the Santa Ana Freeway (1-5) interchange; see Figure 1. Project Location. Project Description: To enhance the safety of Atlantic Blvd. over the Los Angeles River and improve the intersection performance at District Blvd., the City of Vernon proposes to widen Atlantic Blvd. from north of the Los Angeles River to 800 feet south of the intersection with District Blvd. The project involves widening Atlantic Boulevard for approximately 1,300 linear feet to provide traffic shoulders, standard sidewalks and a right turn lane over the Atlantic Blvd. Bridge. The proposed roadway configuration includes six 11-foot through traffic lanes, one 11-foot right turn lane, 4-foot minimum width shoulders and a median varying from 3 feet to 8 feet at District Blvd. To accomplish the bridge widening, the pier wall supports will be widened approximately 16 feet to the west and 19 feet to the east. In addition, debris nosing walls will be installed upstream of the bridge, extending approximately 30 feet upriver. Construction of the pier widening and debris wall will include drilling piles in the River. The bridge widening will require additional easement right-of-way (ROW) from the Los Angeles County Flood Control District within the Los Angeles River. ROW will also be required from the LA Junction railroad and the Los Angeles Department of Water and Power. The roadway to the south of District Blvd. will be widened to the east in order to match the bridge width. At the south end of the bridge, additional ROW easements will be taken at two properties on the east side of Atlantic at District Blvd. The existing curb line will remain, with no modifications, on the west side of Atlantic Blvd, south of District Blvd, near the existing elementary school. • Total Acres of Project Footprint (Bridge Work Only): The total project area is approximately 3.4 acres. Approximately 23,100 square feet (0.53 acres) of net area will be added to the existing bridge, including additions to both the west and east sides of the bridge. 1-7 PROPOSED ATLANTIC BLVD. BRIDGE WIDENING: INTITIAL STUDY/NEGATIVE DECLARATION • Construction Methods: To accomplish this bridge widening, new piles will be drilled in -stream on both sides of the bridge to support the additional lanes. Currently, there are six bents in -stream supporting the bridge. These bents comprise a series of piles and are aligned parallel to the channel flow and at an angle to the centerline of the bridge and roadway spanning the channel. To each of these bents, piles will be added to the west and east ends. In addition to the bridge foundation, debris walls will be added on the upstream side with their own foundations. Construction will initially consist of pile installation and excavating and drilling of piles to support the bridge. Small diameter, cast -in -drilled -hole (CIDH) concrete piles will be used for debris walls in -stream and large -diameter CIDH piles will be used at the bridge piers. The CIDH piles, pile caps, and deck widening will require poured concrete in steel or wooden forms. In this manner, no temporary structures will be constructed on the bottom of the channel. Bridge construction will require heavy equipment, such as a drill rig and crane for lifting the deck beams. The Los Angeles Department of Water and Power maintenance roads may be used as staging areas for construction material and equipment. The roadway portion of the bridge will involve typical paving construction equipment. • Construction Schedule: The overall construction duration is anticipated to be approximately 16 months and be carried out in two phases: 1) Structure construction and roadway construction widening on the east side; and 2) Structure construction widening on the west side. Structure construction will occur within the first and last four months of construction while roadway construction will begin with at the contract start and continue until completed. • Required Permits anti Approvals: 1) U.S. Army Corps of Engineers (ACOE) Nationwide 404 permit; 2) California Department of Fish and Game (CDFG) Section 1601 Streambed Alteration Agreement; 3) Regional Water Quality Control Board (RWQCB) 401 Water Quality Certification; and 4) County of Los Angeles Flood Control District approval for use of maintenance roads along the channel and to work within the channel. 1.10 SURROUNDING LAND USES AND SETTING The project site is surrounded by industrialized land uses to the north, east, south and west. The Los Angeles River crosses the site at Atlantic Boulevard where the proposed improvements are to be constructed. The bridge provides a 6-lane elevated crossing over the Los Angeles River. At this location, the River is completely channelized with concrete lining and provides sufficient flood protection for the typically low -flow waterway. Railroad tracks cross the approaches on both River banks. As both railroad tracks are siding tracks with no high speed through trains, the crossings are at grade, and traffic is controlled by crossing lights, not crossing gates. On the north river bank, Los Angeles Department of Water and Power (LADWP) electrical transmission towers are parallel to the River. A bike path begins at Atlantic Blvd. and is along the south River bank to the east. 1-8 PROPOSED ATLANTIC BLVD. BRIDGE WIDENING: INTITIAL STUDY/NEGATIVE DECLARATION Figure 1.

BRIDGE WIDENING: INTITIAL STUDY/NEGATIVE DECLARATION 2.1 ENVIRONMENTAL CHECKLIST AND ANALYSIS EVALUATION OF ENVIRONMENTAL IMPACTS: 1) A brief explanation is required for all answers except "No Impact" answers that are adequately supported by the information sources a lead agency cites in the parentheses following each question. A "No Impact" answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved (e.g. the project falls outside a fault rupture zone). A "No Impact" answer should be explained where it is based on project -specific factors as well as general standards (e.g. the project will not expose sensitive receptors to pollutants, based on a project -specific screening analysis). 2) All answers must take account of the whole action involved, including off -site as well as on -site, cumulative as well as project -level, indirect as well as direct, and construction as well as operational impacts. 3) 'Potentially Significant Impact' is appropriate if there is substantial evidence that an effect is significant. If there are one or more 'Potentially Significant Impact" entries when the determination is made, an EIR is required. 4) 'Potentially Significant Unless Mitigation Incorporated" applies where the incorporation of mitigation measures has reduced an effect from 'Potentially Significant Impact" to a "Less than Significant Impact." The lead agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level (mitigation measures from Section 17, "Earlier Analysis," may be cross-referenced). 5) Earlier analysis may be used where, pursuant to the tiering, program EIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration. Section 15063 (c) (3) (D). Earlier analyzes are discussed in Section 17 at the end of the checklist. 6) Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impacts (e.g. general plans, zoning ordinances). Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated. A source list should be attached, and other sources used or individuals contacted should be cited in the discussion. The following is a checklist used to address the different environmental disciplines that could be potentially impacted by the proposed project. -12 PROPOSED ATLANTIC BLVD.

(a) There are no known designated scenic vistas located in or near the project site that provide views of the project site. Since there are no designated scenic vistas, no impacts are anticipated. (b) The proposed project site is not located within a state scenic highway corridor and would not remove or damage any natural resource. The site is characteristic of an industrially developed area with an absence of scenic resources, including historic buildings. (c) The proposed project is consistent with existing and surrounding land uses. The existing use will continue upon project completion. No impacts to visual character will occur. (d) The proposed project does not involve the installation of new or additional light standards. There are no sensitive land use receptors in the area. No impacts to day or nighttime views are expected. -13 PROPOSED ATLANTIC BLVD. BRIDGE WIDENING: INTITIAL STUDY/NEGATIVE DECLARATION 2.1.2 Agricultural Resources In determining whether impacts to agricultural resources are significant environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model (1997) Prepared by the California Dept. of Conservation as an optional Model to use in assessing impacts on agriculture and farmland. Would the project a) Convert Prime Farmland, Unique Farmland, or ❑ ❑ ❑ 0 Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use? b) Conflict with existing zoning for agricultural use, or a ❑ ❑ ❑ 0 Williamson Act contract? c) Involve other changes in the existing environment, ❑ ❑ ❑ 0 which, due to their location or nature, could result in conversion of Farmland, to non-agricultural use? Explanation (a) According to Appendix G of the State CEQA Guidelines and the California Department of Conservation, a project will have a significant impact on agricultural resources if it falls into any of the following state and federal farmland designations: Prime Farmland; Farmland of Statewide Importance; or Unique Farmland (US Department of Conservation). Since the proposed project would take place within an area designated as General Industrial (General Industrial [M] zone district) by the City of Vernon General Plan and which is not being used for agricultural purposes, no agricultural impacts would result. (b) The proposed project is located in an area that is not zoned for agriculture (see 3.3.2(a)). The project would not result in direct or indirect impacts to agricultural resources. The project would not affect an agricultural preserve under a Williamson Act contract because no such contract exists. (c) The project area is not located on agricultural land or farmlands. The project would neither directly nor indirectly result in the conversion of Prime, Unique, or other Farmland of Statewide Importance to a non-agricultural use. -14 PROPOSED ATLANTIC BLVD. BRIDGE WIDENING: INTITIAL STUDY/NEGATIVE DECLARATION 2.1.3 Air Quality Where available, the significance criteria established by the applicable air quality management or air pollution control district may be relied upon to make the following determinations. Would the project: a) Conflict with or obstruct implementation of the ❑ ❑ 0 ❑ applicable air quality plan? b) Violate any air quality standards or contribute ❑ ❑ 0 ❑ substantially to an existing or projected air quality standard? c) Result in a cumulatively considerable net increase of ❑ ❑ ❑ 0 any criteria pollutant for which the project region is non -attainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)? d) Expose sensitive receptors to substantial pollutant ❑ ❑ 0 ❑ concentrations? e) Create objectionable odors affecting a substantial ❑ ❑ 0 ❑ number of people? Explanation (a) The South Coast Air Quality Management District (SCAQMD) Governing Board adopted the 2003 Air Quality Management Plan (AQMP) on August 1, 2003 to achieve compliance with State and federal air quality standards. The 2003 AQMP updates the attainment demonstration for the federal standards for ozone and particulate matter (PMio); replaces the 1997 attainment demonstration for the federal carbon monoxide (CO) standard and provides a basis for a maintenance plan for CO for the future; and updates the maintenance plan for the federal nitrogen dioxide (NO2) standard that the South Coast Air Basin (Basin) has met since 1992. The 2003 AQMP is consistent with and builds upon the approaches taken in the 1997 AQMP and the 1999 Amendments to the Ozone SIP for the South Coast Air Basin for the attainment of the federal ozone air quality standard. The AQMP provides the framework for air quality planning within the South Coast Air Basin, and lay out the SCAQMD's strategy to reduce emissions of non -attainment pollutants. Potential sources of air pollutant emissions (PMto, CO, 03, NOx, ROCs, SOx) include heavy equipment such as cranes, drilling rigs, concrete trucks and mixers, and other equipment used during construction. The proposed project would not generate any increase in vehicle trips to the site upon implementation of the project. Rather, the proposed project would allow for more even traffic flow along Atlantic Boulevard, ultimately improving traffic congestion reducing air pollutant emissions. There will be fewer stop/start occurrences and less idle time. Due to the short duration of construction, as well as the size and scope of the project, the temporary nature of air emission, and the minimal amount of construction equipment used, the proposed project would not obstruct the implementation of the AQMP. -15 PROPOSED ATLANTIC BLVD. BRIDGE WIDENING: INTITIAL STUDY/NEGATIVE DECLARATION (b) State and federal agencies have set ambient air quality standards for certain air pollutants. National Ambient Air Quality Standards (NAAQS) have been established for carbon monoxide (CO), Ozone (03), Sulfur Dioxide (S02), Nitrogen Dioxide (NO2), inhalable particulate matter (PMio), and lead (Pb). The state's ambient air quality standards for these and other pollutants are more stringent than the corresponding federal standards. Areas are classified under the federal Clean Air Act as either "attainment" or "non -attainment" areas for each criteria pollutant, based on whether the NAAQS have been achieved or not. The SCAB has not attained the state and federal standards for 03, CO, PM2.5, and PM10 and is a maintenance area for NO2 of the six pollutants, and thus is designated as a non -attainment area. Because of the short duration of construction and the size and scope of the project, air pollutant emissions are not considered substantial or significant. Therefore, the proposed project would not violate any air quality standard. (c) Since the proposed project is not expected to generate an increase in criteria air pollutants, cumulatively considerable net increases in such pollutants in which the region is in non - attainment is not expected. (d) There are no residences immediately adjacent or in close proximity to the project site. Exposure to increases in air pollutant emissions would be intermittent and not considered significant as explained in the previous responses. (e) The proposed project would involve paint striping, and the mixing of asphalt and concrete for paving the newly widened lanes on the bridge. Odors emitted from these activities are considered nominal in that they are short term in nature and there are no sensitive land use receptors in the vicinity. The area is primarily industrial development. Less than significant impacts will occur.

Explanation (a) The proposed project involves pile drilling within the Los Angeles River that is influenced by tidal flows. It is, hence, considered "waters of the U.S." under the jurisdiction of the U.S. Army Corps of Engineers. The channel itself at Atlantic Boulevard is concrete -lined and devoid of vegetation. Although, the channel provides a water source for shorebirds and migratory birds, an emergent or submerged vegetative community does not exist at the construction site. Construction activities would temporarily disturb the existing benthic habitat and discourage wildlife use of the area. Implementation of the proposed project would result in the loss of approximately 6,600 square feet of benthic habitat from the placement of the 184 piles within the channel. It would also result in indirect loss of productivity on phytoplankton and periphyton (algae, fungi, and bacteria living on submerged surfaces) below the bridge and within the channel during high flow periods from increases in shade below the bridge. No sensitive species are known to permanently inhabit the Los Angeles River at this location, although sensitive marine birds species may, on occasion, stop to forage in the area. These effects are biologically less than significant considering the extent of existing benthic habitat, regular tidal flow of water, and the small amount of the change from existing conditions. (b) The proposed project involves construction along the banks of, and within the water column of the Los Angeles River, considered to be jurisdictional habitat under the California Department of Fish and Game and the US Army Corps of Engineers. Construction activities would temporarily disturb the riparian and aquatic habitat within and along the banks of the channel. The project would not block tidal flows, but would be staged and constructed from the ground surface banks, or from the existing bridge. In no case would the tidal flows be impeded by the project. Implementation of the proposed project would result in the permanent loss of 6,600 square feet of riparian habitat within the channel and bank. The effects of construction are biologically less than significant considering that the channel would neither be de -watered, nor the daily fluctuations in water level affected during construction. (c) The proposed project requires the placement of 184 piles within the Los Angeles River, considered "waters of the U.S." According to the U.S. Army Corps of Engineers, the agency which regulates such resources, the amount lost is not of sufficient size to constitute substantial adverse impacts. Less than significant impacts will occur. -17 PROPOSED ATLANTIC BLVD. BRIDGE WIDENING: INTITIAL STUDY/NEGATIVE DECLARATION (d) The surrounding area is heavily built out and industrial activities are predominant. Development of the site would not permanently inhibit wildlife movement. Construction activities, however, may inhibit short-term use of the immediate area by birds and fish, but this impact would be temporary and not significant. Construction activities would involve pile driving and drilling, which are sources of increased noise, vibration, and dust. These impacts would be temporary. Native resident or migratory fish or wildlife within the area affected by the project would likely continue to utilize other portions of the channel during construction. These are less than significant impacts. (e) The proposed project does not involve the removal or encroachment of any tree. The removal of vegetation would affect only ruderal (weedy) species; therefore, the impacts would be less than significant. The proposed project would not conflict with locally adopted conservation plans and policies. The City is not enrolled in a Natural Community Conservation Program, nor has there been a 2.1.5 Cultural Resources a) Cause a substantial adverse change in the ❑ ❑ ❑ 0 significance of a historical resource as defined in § 15064.5? b) Cause a substantial adverse change in the ❑ 0 ❑ ❑ significance of an archaeological resource pursuant to § 15064.5? c) Directly or indirectly destroy a unique paleontological ❑ ❑ ❑ 0 resource or site or unique geologic feature? d) Disturb any human remains, including those interred ❑ ❑ ❑ 0 outside of formal cemeteries? Explanation (a) The proposed project site involves widening of an existing bridge crossing. In accordance with Section 106 of the National Historic Preservation Act (NHPA), a historical architectural survey was completed for the project site (March 1, 2005) to identify historic properties that may lie within the study area (see Appendix A: Section 106 Historic Property Survey Report — Attachment I: Historic Resources Evaluation Report). The Area of Potential Effect (APE) boundaries were delineated in conjunction with the Caltrans PQS from CAD drawings for the proposed right-of-way as the basis for most of the affected area plus 2-feet along new sidewalks/curbs and 10-feet along the bridge span. Delineation has been included for two affected parcels: southeast corner of Atlantic and District Boulevard and northeast corner of Atlantic and District Boulevard. An evaluation of the built environment for historic resources included the Atlantic Boulevard Bridge over Los Angeles River and one row of parcels abutting the east and west edges of Atlantic Boulevard, covering an area from one block south of District Boulevard northward to the 710 Freeway southbound onramp. -18 PROPOSED ATLANTIC BLVD. BRIDGE WIDENING: INTITIAL STUDY/NEGATIVE DECLARATION URS identified three properties in the study area that required further evaluation. These include Service Oil, Inc. (formerly Seaside Oil Company, established 1932), and Atlantic Boulevard Bridge over Los Angeles River (erected 1931) and International Paper (1960), abutting the northeast quadrant of the project APE. A fourth property, Thermador Electric Manufacturing Company (1930s to 1943) is also located within the APE, but will be demolished and the utilities realigned as a separate project in agreement with the City of Vernon; this property was formerly owned by the Woolwine Metal products Company (1927-1930s). The building will be demolished prior to beginning construction for the street widening task of the bridge widening project. This property has been evaluated and determined ineligible for listing in the CRHR or NRHP. The survey determined that none of the properties are eligible for listing on the National Register of Historic Places (NRHP). Similarly, for the purposes of CEQA, the properties identified in the project area that were constructed before 1960 were determined not eligible for listing on the California Register of Historical Resources. Also, as defined in Section 15064.5 of CEQA, the Project would result in no impact to cultural resources (the industrial buildings and associated outbuildings) because the Project would not cause a substantial adverse change in the significance of a historical resource. No significant impacts will occur. (b) In accordance with Section 106 of the NHPA, an archeological survey was completed for the project site (March 1, 2005) to identify historic properties that may lie within the study area. The survey area included the proposed project construction footprint, easements, and staging areas (see Appendix A: Section 106 Historic Property Survey Report — Attachment II: Archeological Survey Report). The survey found no archeological resources eligible for listing on the National Register of Historic Places (NRHP). And, as defined in Section 15064.5 of CEQA, the Project would result in no impact to cultural resources because under (b) the Project would not cause a substantial adverse change in the significance of an archeological resource. Similarly, the project would have under (c) not impact on human remains: Because no human remains have been reported in the project area, the Project would not likely disturb human remains, including those interred outside of formal cemeteries. Although, the archaeological records search, supplemental archival research, and field survey suggest that no known archeological exist with the project area. However, due to the proximity of the Los Angeles River and former historical built environment features, buried archeological features and deposits may exist within the project area. These could include, but are not limited to, Native American archaeological remains such as stone tool scatters, habitation artifacts of bone and vegetal composition, and isolated burials. Historical archaeological deposits could consist of privy pits, refuse deposits, and subsurface remnants of the earlier built environment. In case buried archeological features and deposits are found within the project area, the following mitigation measure shall be implemented to reduce potential impacts to below the level of significance: CR-1: Ground disturbing activities that take place in native soils outside of the channelized portion of the Project Area (i.e. on the river terrace) shall be monitored at the discretion of a qualified archaeologist. Ground disturbing and excavation activities that necessitate monitoring include the following: a) removal of the built environment directly related to exposing native soils, b) digging of any kind, including footings, and c) soil spreading. Pile driving does not necessitate monitoring as it precludes the discovery of cultural resources. -19 PROPOSED ATLANTIC BLVD. BRIDGE WIDENING: INTITIAL STUDY/NEGATIVE DECLARATION The project archeologist shall attend all preconstruction meetings and shall have the authority to temporarily halt or redirect construction equipment if cultural materials are encountered so that they may be documented and recovered as appropriate. In accordance with the California Health and Safety Code (Public Resources Code 7050.5), and California Environmental Quality Act (regarding human remains); in the event human remains are encountered during the construction activities, all work in that area shall cease. The Los Angeles County Coroner shall be notified immediately of the remains, who shall determine whether they are of historic or recent demise. PRC 7050.5 requires the county coroner to contact the Native American Heritage Commission within 24 hours if the coroner determines that the remains are of Native American origin. Implementation of CEQA, PRC 7050.5 and PRC 5097.98 and coordination with the Native American most likely descendants (ULD) to recover, treat and re -inter human remains and associated grave goods in a respectful manner can mitigate significant impacts of these remains to a less than significant level.

Explanation (a) Rupture and Seismic Ground Shaking: As part of the southern California region, the project site is located within an earthquake -prone region. There are no known active faults that traverse the project site, although significant damage would result from ground shaking caused by a major earthquake from nearby faults. The nearest known active fault is the Elysian Park Seismic Zone, approximately four miles to the north of the project site. In the event of an earthquake, strong seismic groundshaking would result (see Appendix 13: Preliminary Geotechnical Memorandum). Liquefaction: The project site does exist within an area of historic occurrence of liquefaction (see Appendix 13: Preliminary Geotechnical Memorandum). Due to the generally shallow depth of historically high groundwater and the generally unconsolidated nature of the Late Holocene deposits, the potential for soil liquefaction during an earthquake is considered moderate to high at the site. The California Geological Survey (CDMG, 1998) has mapped the site as being within a Liquefaction Hazard Zone. The following mitigation measure shall be implemented to reduce potential impacts to below the level of significance: GS-1: Prior to design, a final foundation investigation should be performed to determine the final pile type and depth. The investigation findings will be submitted to the City of Vernon Community Services Department — Public Works Division for review and approval. Landslide: The site is flat with no apparent hillsides or slopes which would otherwise result in the potential for landslides. Less than significant impacts will occur. (b) The proposed project does not involve re -grading of the surface nor is the project site characterized by prominent slopes or hillsides which would precipitate erosion or loss of topsoil. No impacts are anticipated. (c) As described in preceding explanation 3.3.6(a), the site may be subject to liquefaction. Mitigation measure GS-1 would be employed to reduce potential impacts to below the level of significance. Therefore, less than significant impacts are anticipated. Minimal ground disturbance or topographical changes are anticipated, therefore, no impacts relating to on- or off -site landslide, lateral spreading, or subsidence would occur. (d) The proposed project involves minimal ground disturbance during the placement of the piles. However, the potential for risk to life or property from the expansion of soils does not exist. No significant impacts will occur. -21 PROPOSED ATLANTIC BLVD. BRIDGE WIDENING: INTITIAL STUDY/NEGATIVE DECLARATION (e) The proposed project does not involve the installation of septic tanks.

Explanation (a) The proposed project does not require the transport, use, or disposal of hazardous materials such as asbestos, lead based paints and PCBs. No significant project -related impacts will occur. (b) The proposed project involves the relocation of utility lines and minimal demolition of curbs and sidewalks. No habitable structures will be constructed. However, heavy equipment, such as cranes and drilling rigs, will be used that could result in the combustion of flammable fuels. The likelihood of such an occurrence is minimal. Additionally, there is the potential for unforeseen -22 PROPOSED ATLANTIC BLVD. BRIDGE WIDENING: INTITIAL STUDY/NEGATIVE DECLARATION collapse of the piles that could result in inadvertent discharge of concrete into the water. To reduce the risk of such an occurrence, the following mitigation measure is recommended: H])E M-1: The final design plans and specifications shall require that the contractor for construction of the improvements prepare and submit to the City of Vernon Environmental Health Department for approval a Hazardous Materials Spill Prevention and Containment Plan. (c) The proposed project would not result in the use or emission of hazardous or actively hazardous materials, substances, or waste. No significant impacts will occur. (d) The site is not located on a list of hazardous materials site. The nearest CERLCIS Hazardous Waste Site is approximately 1 mile to the north of the project site (EPA, 2005). No significant impacts will occur. (e,f) The project is not located within an airport land use plan or where such a plan has been adopted. The project site is not located near or within a public airport or public use airport, and would not result in safety hazards to people residing or working in the project area. No new health hazards would be created. (g) The proposed project involves the partial closure of Atlantic Boulevard during the project's construction. Through traffic would be maintained, though constricted, in the event of an emergency at any of the nearby industrial facilities. Less than significant impacts will occur. (h) The proposed project site is located within a heavily industrialized area with little to no vegetation or brush material. Fire hazards and risks are associated with human induced or industrial induced fires. Activities associated with the proposed project are consistent with existing activities and are not expected to increase the fire hazard.

Drilling the piles into the River bottom would result in the displacement of soil and increase turbidity in the water. Additionally, the use of drill rig and other diesel powered heavy equipment would result in residual release of hydrocarbons into the water below. The project itself does not involve the direct or immediate discharge of any substance, manufacturing byproduct or waste discharge. However, the potential for unforeseen collapse of the piles could result in inadvertent discharge of concrete into the water (see Appendix C: Water Quality Report). To reduce the risk of such an occurrence PROPOSED ATLANTIC BLVD. BRIDGE WIDENING: INTITIAL STUDY/NEGATIVE DECLARATION and the potential of violating water quality standards, the following mitigation measure is recommended: HWQ-1: The final design plans and specifications shall require that the contractor prepare and submit to City of Vernon Environmental Health Department for approval a Hazardous Materials Spill Prevention and Containment Plan. b) The proposed project does not involve direct conversion of pervious to impervious surface given that the impervious surface to be constructed is to occur above grade. Additionally, the proposed project does not require any water so as to significantly deplete water supplies. No significant impacts will occur. c) The proposed project would not alter the existing drainage patterns; rather, existing drainage patterns would be maintained. All surface water flows would be directed back into the Los Angeles River, the main watercourse. Construction of the piles within the banks of the channel may result in minor soil erosion or siltation within the channel due to disturbance of the soil by heavy equipment and the potential for loose soil to migrate down the banks and into the water. Less than significant impacts will occur. d) See preceding explanation 3.3.8 (c). e) The proposed project does not involve the conversion of pervious to impervious surface, although impervious surface area above the channel will increase. Any increase in surface water flows would be immediately directed back into the flood control channel. Additionally, the overall amount of run-off is not expected to exceed the capacity of the existing storm drain system. Less than significant impacts will occur. f) The City of Vernon does not include any floodplain area as identified by the Federal Emergency Management Agency.' No significant impacts will occur. g) See preceding explanation 3.3.8 (f).

Explanation (a) Construction of the proposed project would result in the increase of noise levels during the daytime hours. However, the anticipated increase is not expected to be substantial or exceed established standards given that the primary noise source is from heavy truck traffic along Atlantic Boulevard associated with the industrial activities within the vicinity. There is a school located in the vicinity of the project site on Atlantic Boulevard south of District Boulevard at a distance of approximately 450 feet. The increased noise level from construction activities is not expected to double and would be temporary and short-term in nature and duration. Operation of the proposed project would not introduce a new noise source. Less than significant impacts will occur.

The project would not result in the need for new or altered facilities or services related to fire protection. During construction activities, the bridge will be narrowed to 2-lanes northbound at Atlantic and District which would degrade AM peak hour LOS E to LOS F while the PM peak hour LOS will remain at LOS C (see Appendix D: Traffic Analysis Memorandum). This may affect the response time for fire protection services. However, through traffic would continue and emergency access would be maintained. Such an increase is considered less than significant because of the temporary duration of construction activities. Less than significant impacts will occur. Police Protection: The proposed project would not increase the demand for police protection services. The proposed project is roadway expansion project and is not a likely target for vandals or criminal activity. The City of Vernon Police Department would continue their protection services to the site and surrounding area. During construction activities, the bridge will be narrowed to 2-lanes northbound at Atlantic and District which would degrade AM peak hour LOS E to LOS F while the PM peak hour LOS will remain at LOS C (see Appendix D: Traffic Analysis Memorandum).

Explanation (a) During construction activities, traffic would nominally increase primarily from trips made by trucks and construction workers to the site. During narrowing the bridge to 2-lanes northbound at Atlantic and District would degrade AM peak hour LOS E to LOS F while the PM peak hour LOS will remain at LOS C (see Appendix D: Traffic Analysis Memorandum). However, such an increase is considered less than significant because of the temporary duration of construction activities. Additionally, the proposed project would not result in new vehicle trips to the site. The proposed project would actually alleviate and improve traffic along Atlantic Boulevard (see Appendix D: Traffic Analysis Memorandum). Less than significant impacts will occur. (b) As stated in response 3.3.15(a), no new trips would be generated upon implementation of the proposed project. The implementation of the proposed project will provide operational and safety improvements to the intersection of Atlantic Boulevard with District Boulevard in all future year scenarios by adding a dedicated SBR turn lane across the bridge. The overall LOS with project implementation will be LOS D. For future condition (2020 AM and PM and 2030 AM and PM) as well, the overall LOS with project implementation will be LOS D (see Appendix D: Traffic Analysis Memorandum). There would be no long- term operational traffic impacts. (c) The project would not have direct access to or use of any air transportation facilities, and would not affect air traffic patterns. No significant impacts will occur. (d) The proposed project would alter the design of existing traffic circulation systems, however, the alterations would be designed in compliance with the safety standards and would result in improvements in the flow of traffic. The proposed project would not introduce any use incompatible with the local land uses. Less than significant impacts will occur.

The facility's permitted maximum disposal capacity is 13,200 tons/day and has approximately 19 percent of the capacity remaining.3 The facility would be able to accommodate such waste. Less than significant impacts will occur. (g) The proposed project would comply with all federal, state, and local statutes and regulations related to solid wastes. Less than significant impacts will occur. a) Does the project have the potential to degrade the quality ❑ 0 ❑ ❑ of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? b) Does the project have impacts that are individually ❑ ❑ p ❑ limited, but cumulatively considerable? ("Cumulatively considerable" means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects)? c) Does the project have environmental effects which will ❑ ❑ 0 ❑ cause substantial adverse effects on human beings, either directly or indirectly? Explanation (a) The proposed project would potentially affect geology and soils, and water quality within the project area. Compliance with the recommended mitigation measures would ensure proper protection and minimization of such impacts. The proposed project would not affect fish or wildlife species, or cause a fish or wildlife population to drop below self-sustaining levels.

BRIDGE WIDENING: INTITIAL STUDY/NEGATIVE DECLARATION would not threaten to eliminate a plant or animal community or reduce a number of a rare or endangered plant or animal. There are no structures or properties within the project area that are eligible for listing on the National Register for Historic Places (NRHP) or California Register of Historical Resources. Thus, the proposed project will not impact any historic structures or areas associated with major periods of California history or prehistory. The proposed project would not degrade the quality of these aspects of the environment. (b) The proposed project would occur over a period of 16 months and have potentially significant impacts on geology and soils, hazards and hazardous materials, and hydrology and water quality. Compliance with the recommended mitigation measures would ensure that such impacts are not individually limiting. Should any other project be implemented on the Los Angeles River either upstream or downstream from the project site, cumulatively considerable impacts could occur. However, at this time, no such projects are planned and, therefore, cumulative impacts are considered less than significant. (c) Implementation of the proposed project and associated mitigation measures would not result in significant adverse environmental impacts. The project would not cause substantial adverse impacts on human beings, either directly or indirectly. -35 PROPOSED ATLANTIC BLVD. BRIDGE WIDENING: INTITIAL STUDY/NEGATIVE DECLARATION 3.0 SUMMARY OF MITIGATION MEASURES The following mitigation measures are proposed to mitigate the potentially significant environmental impact of the proposed project to less than significant levels: Cultural Resources: In accordance with Section 106 of the NHPA, an archeological survey was completed for the project site (March 1, 2005) to identify historic properties that may lie within the study area. The survey area included the proposed project construction footprint, easements, and staging areas (see Appendix A: Section 106 Historic Property Survey Report — Attachment II: Archeological Survey Report). The survey found no archeological resources eligible for listing on the National Register of Historic Places (NRHP). And, as defined in Section 15064.5 of CEQA, the Project would result in no impact to cultural resources because under (b) the Project would not cause a substantial adverse change in the significance of an archeological resource. Similarly, the project would have under (c) not impact on human remains: Because no human remains have been reported in the project area, the Project would not likely disturb human remains, including those interred outside of formal cemeteries. Although, the archaeological records search, supplemental archival research, and field survey suggest that no known archeological exist with the project area. However, due to the proximity of the Los Angeles River and former historical built environment features, buried archeological features and deposits may exist within the project area. These could include, but are not limited to, Native American archaeological remains such as stone tool scatters, habitation artifacts of bone and vegetal composition, and isolated burials. Historical archaeological deposits could consist of privy pits, refuse deposits, and subsurface remnants of the earlier built environment. In case buried archeological features and deposits are found within the project area, the following mitigation measure shall be implemented to reduce potential impacts to below the level of significance: CR-1: Ground disturbing activities that take place in native soils outside of the channelized portion of the Project Area (i.e. on the river terrace) shall be monitored at the discretion of a qualified archaeologist. Ground disturbing and excavation activities that necessitate monitoring include the following: a) removal of the built environment directly related to exposing native soils, b) digging of any kind, including footings, and c) soil spreading. Pile driving does not necessitate monitoring as it precludes the discovery of cultural resources. The project archeologist shall attend all preconstruction meetings and shall have the authority to temporarily halt or redirect construction equipment if cultural materials are encountered so that they may be documented and recovered as appropriate. In accordance with the California Health and Safety Code (Public Resources Code 7050.5), and California Environmental Quality Act (regarding human remains); in the event human remains are encountered during the construction activities, all work in that area shall cease. The Los Angeles County Coroner shall be notified immediately of the remains, who shall determine whether they -36 PROPOSED ATLANTIC BLVD. BRIDGE WIDENING: INTI TIAL STUDY/NEGATIVE DECLARATION are of historic or recent demise. PRC 7050.5 requires the county coroner to contact the Native American Heritage Commission within 24 hours if the coroner determines that the remains are of Native American origin. Implementation of CEQA, PRC 7050.5 and PRC 5097.98 and coordination with the Native American most likely descendants (MLD) to recover, treat and re -inter human remains and associated grave goods in a respectful manner can mitigate significant impacts of these remains to a less than significant level. Geology and Soils: The project site does exist within an area of historic occurrence of liquefaction (see Appendix A: Preliminary Geotechnical Memorandum). Because of the generally shallow depth of historically high groundwater and the generally unconsolidated nature of the Late Holocene deposits, the potential for soil liquefaction during an earthquake is considered moderate to high at the site. The California Geological Survey (CDMG, 1998) has mapped the site as being within a Liquefaction Hazard Zone. The following mitigation measure shall be implemented to reduce potential impacts to below the level of significance: GS-1: Prior to design, a final foundation investigation should be performed to determine the final pile type and depth. The investigation findings will be submitted to the City of Vernon Community Services Department — Public Works Division for review and approval. Hazards and Hazardous Materials: The proposed project involves the relocation of utility lines and minimal demolition of curbs and sidewalks. No habitable structures will be constructed. However, heavy equipment such as cranes and drilling rigs would be used that could result in the combustion of flammable fuels. The likelihood of such an occurrence is minimal. Additionally, there is the potential for unforeseen collapse of the piles that could result in inadvertent discharge of concrete into the water. To reduce the risk of such an occurrence, the following mitigation measure is recommended: HHM-1: The final design plans and specifications shall require that the contractor for construction of the improvements prepare and submit to the City of Vernon Environmental Health Department for approval a Hazardous Materials Spill Prevention and Containment Plan. Hydrology and Water Quality: The proposed project involves the installation of piles within the Los Angeles River. Drilling the piles into the river bottom would result in the displacement of soil and increase turbidity in the water. Additionally, the use of pile drivers/drill rig and other diesel powered heavy equipment would result in residual release of hydrocarbons into the water below. The project itself does not involve the direct or immediate discharge of any substance, manufacturing byproduct or waste discharge. However, the potential for unforeseen collapse of the piles could result in inadvertent discharge of concrete into the water. To reduce the risk of such an occurrence and the potential of violating water quality standards, the following mitigation measure is recommended: HWQ-1: The final design plans and specifications shall require that the contractor for construction of the improvements prepare and submit to the City of Vernon Environmental Health Department for approval a Hazardous Materials Spill Prevention and Containment Plan. -37 PROPOSED ATLANTIC BLVD. BRIDGE WIDENING: INTITIAL STUDY/NEGATIVE DECLARATION Public Services: The proposed project will not create any permanent structures that will require the addition or alteration of school facilities. The construction of the bridge widening will require the use of construction equipment in the channel of the Los Angeles River and vehicle traffic on Atlantic Blvd. and District Blvd. Most if not all of the construction traffic will access the freeway to the north of the bridge or District Blvd. in the east/west direction. The contractor will be required to minimize the construction traffic to the south and thus minimize the impact on the school located south of District Blvd. However, in accordance to comments received from the Los Angeles Unified School District, the following mitigation measures are recommended to provide for public and school safety during construction. PS-1: The final design plans and specifications shall require that the contractor maintain unrestricted access for school buses during construction. PS-2: The final design plans and specifications shall require that the contractor not endanger passenger safety or delay student drop-off or pickup due to changes in traffic patterns, lane adjustments, altered bus stops, or traffic lights. PS-3: The final design plans and specifications shall require that the contractor maintain safe convenient pedestrian routes to LAUSD schools. PS-4: The final design plans and specifications shall require that the contractor install appropriate traffic controls to ensure pedestrian safety and vehicular safety during construction. PS-5: The final design plans and specifications shall require that the contractor does not haul construction equipment or materials past affected school sites, during school arrival and dismissal times. PS-6: The final design plans and specifications shall require that the contractor does not stage or park construction -related vehicles, including worker -transport vehicles, adjacent to school sites. PS-7: The final design plans and specifications shall require that the contractor install barriers and/or fencing to secure to secure construction equipment and site to prevent trespassing, vandalism, and short-cut attractions. PS-8: The final design plans and specifications shall require that the contractor provide security patrols to minimize trespassing, vandalism, and short-cut attractions. Transportation/Traffic: The widening of the bridge will require the widening of Atlantic Blvd. and will require the reconstruction of the driveway access to private property at the northeast corner of Atlantic Blvd. and District Blvd. The emergency access will be maintained at all times since this property houses a fuel distribution facility. TT-1: The final design plans and specifications shall provide for reconstruction of the existing driveway access to Atlantic Blvd. for the property at the northeast corner of Atlantic Blvd. and District Blvd. Emergency access will be maintained at all times to the fuel distribution facility on the site. -38 PROPOSED ATLANTIC BLVD.

The bridge will be widened to accommodate six 11 foot wide lanes, traffic shoulders, a median, sidewalks and a southbound right turn lane. In order to widen the bridge the pier wall supports will be extended on both sides of the bridge. Atlantic Blvd. will be widened from 52' Place to District Blvd. to increase the width of the northbound lanes and dedication of right of way will be required from the private property along this section of Atlantic Blvd. In order to proceed with the design of these improvements, the City Council must adopt a Mitigated Negative Declaration for the project. An Initial Study was prepared in accordance with California Environmental Quality Act (CEQA) and a Notice of Intent to adopt the Mitigated Negative Declaration was circulated. The Notice of Intent, Initial Study, Mitigated Negative Declaration, Historical Property Survey and Notice of Completion were also sent to the State of California Clearing House to notice appropriate State Agencies. Herewith for your consideration are the following additional supporting documents: 1. Staff Report; 2.

BRIDGE OVER THE LOS ANGELES RIVER BRIDGE WIDENING AND IMPROVEMENT INITIAL STUDY AND MITIGATED NEGATIVE DECLARATION OCTOBER 2006 The City of Vernon is considering the widening and improvement of the Atlantic Blvd. Bridge over the Los Angeles River to enhance vehicle safety. The project involves the widening of the Atlantic Blvd. Bridge to provide six 11 foot wide traffic lanes, one 11 foot wide south bound right turn lane, 4 foot wide road shoulders, a median that varies from 3 foot to 8 foot wide and standard sidewalks. The northbound lanes from 52"a Place to District Blvd. will also be widened. The construction will require the installation of cast -in -place in drilled hole piles into the Los Angeles River riverbed, the construction of pile caps, new bridge decking and the extension of the debris nosing walls in the riverbed using pre -cast driven piles. The widening will be from 500 feet north of the Los Angeles River to 800 feet south of the intersection of District Blvd. The widening will require additional easement right-of-way from the Los Angeles Flood Control District, City of Los Angeles Department of Water and Power and the Los Angeles Junction Railway. Right-of-way easements will also be required from two private properties on the east side of Atlantic Blvd. north and south of District Blvd. In order to proceed to the design phase of this project, an environmental evaluation was conducted by the City of Vernon's consultant, W. Koo and Associates. The Preliminary Environmental Study was submitted to Caltrans and the required environmental reports were completed and submitted for approval. Caltrans has evaluated the environmental reports and has determined that they satisfy the National Environmental Protection Act and has issued a Programmatic Categorical Exclusion. The City of Vernon must now determine if the California Environmental Quality Act (CEQA) is satisfied. W. Koo has prepared an Initial Study and determined that a Mitigated Negative Declaration is the appropriate document for CEQA evaluation. BACKGROUND The Atlantic Blvd. Bridge over the Los Angeles River was constructed in 1931 to serve the Central Manufacturing District (CMD) which had grown from 1923 to 1929 into a 2,800 acre industrial complex composed of stock yards, warehouses, and manufacturing facilities. The CMD was patterned after an industrial/warehousing plan used in Chicago, Illinois and by 1929 had a combined output of goods and freight annually of $30,000,000 making it one of the most valuable industrial districts in the western United States according to reports of that time. Soon after 1931 the U. S. Army Corp of Engineers began the realignment, widening and concrete channelization of the Los Angeles River. By 1941 the river at Atlantic Blvd. had been concrete lined and the bridge was lengthened and improved to accommodate the widening and concrete lining. The bridge is an earth filled arch bridge and has been found to be seismically adequate by the analysis of the consultant, W. Koo and Associates. The existing Atlantic Blvd. Bridge serves as a vital conduit for the 60,000 vehicles a day that traverse this artery to and from the City of Vernon industrial facilities and the cities north and south of this bridge. RIGHT OF WAY The new bridge will require the acquisition of new street easements. Street easements from the Los Angeles County Flood Control District, Los Angeles Junction Railroad, the City of Los Angeles Department of Water and Power and the private properties at the northeast corner and southeast corner of the intersection of Atlantic Blvd. and District Blvd. will be secured prior to the construction of the bridge widening. UTILITIES The Atlantic Blvd. Bridge will incorporate in its design the relocation of the existing water line and gas line to new locations on the bridge. The existing overhead electrical lines will be relocated prior to the construction of the bridge. The two railroad crossings will be improved with new signal devices to permit the safe crossing of rail cars. The traffic signal at the intersection of Atlantic Blvd. and District Blvd. will be pre- empted during the crossing of the rail cars. TRAFFIC Atlantic Blvd. is shown on the City's master plan as an arterial that carries north/south traffic through the eastern portion of the City of Vernon. The Atlantic Blvd. Bridge over the Los Angeles River is a vital link along this arterial and carries almost 60,000 vehicles a day. The bridge has 6lanes with no parking allowed but the lanes are narrow and obsolete with no shoulders or median. The proposed widening will enhance the movement of the vehicles by creating 11 foot wide lanes with a median and standard sidewalks. The existing right turn lane nouthbound will be extended on to the bridge to permit free flow of traffic to District Blvd. The northbound traffic will be facilitated with a new right turn only lane that will require the widening of the street and the securing of a street easement from the property at the southeast corner of this intersection. PARKING The Atlantic Blvd. Bridge has no parking at this time and parking will not be provided when the widening is completed. AESTHETICS The widening of the bridge will incorporate architectural arches similar to the existing arches in the exterior girder of the bridge widening. The exterior barrier will be designed with an arch shaped relief similar to the existing barrier shape. RECOMMENDATION The Initial Study for the proposed project, the design and construction of the widening of the Atlantic Blvd. Bridge over the Los Angeles River, indicates that the project will not have significant environmental effects if the mitigation measures recommended are implemented. Therefore, it is recommended that a Mitigated Negative Declaration be adopted by the City Council. NOTICE OF A SCHEDULED PUBLIC HEARING REGARDING THE PROPOSED IMPROVEMENT OF THE ATLANTIC BLVD.

For Local Assistance projects off the highway system, use headers in italics) To enhance the safety of Atlantic Boulevard Bridge over the Los Angeles River (Br. No. 53C-0252) and improve intersection performance at District Boulevard, the City of Vernon proposes to widen Atlantic Boulevard from a point immediately north of the Los Angeles River to 800 feet south of the intersection of Atlantic Boulevard and District Boulevard The project involves widening Atlantic Boulevard Bridge, and to provide lane widening, traffic shoulders, standaid sidewalks, and a right -turn lane associated with roadway located at the intersection of Atlantic Boulevard and District Boulevard. To accomplish bridge -widening, the existing pier wall supports will be extended. In addition, debris nosing walls will be installed upstream of the bridge. Construction of the pier -widening and debris walls will include driving Cast -in -place drilled hole (CIDH) piles into the riverbed. The City of Vernon contracted URS Corporation (URS) to conduct a cultural resources survey of the proposed Project site. Project Location and Vicinity Maps are found in the HPSR and Attachment 1: Historical Resources Evaluation Report (HRER) Maps l and 2, and Attachment 11: Archaeological Survey Report _(ASR), Maps 1 and 2. 2. AREA OF POTENTIAL EFFECTS The Area of Potential Effects (APE) for the project was established in consultation with Claudia Harbert, Caltrans PQS Principal Architectural Historian, and Rajesh Jha, local assistance engineer, on January 19, 2006 The APE maps are located in the HPSR and Attachments I & II (HRER and ASR, respectively, Map 3 in each report) found in this Historic Property Survey Report. The Area of Potential Effect (APE) boundaries were delineated in conjunction with the Caltrans PQS from CAD drawings for the proposed right-of-way as the basis for most of the affected area plus 2-feet along new sidewalks/curbs and 10-feet along the bridge span. Delineation has been included for two affected parcels: southeast corner of Atlantic and District Boulevard and northeast corner of Atlantic and District Boulevard. The former has a building on the site, which will be demolished and the utilities realigned as a separate project in agreement with the City of Vernon prior to beginning construction for the street widening task of the bridge widening project. There will be a required partial permanent taking in order to accommodate a right -turn pocket on the northbound side of Atlantic Boulevard at the southern approach to the Atlantic/District Boulevard intersection. There will also be a required partial permanent taking of the parcel located at the northeast corner of Atlantic and District Boulevard to accommodate street widening on northbound Atlantic Boulevard approaching the widened bridge. Structures on this parcel will be left in -situ. Additional delineation has been included for the following: 1. Staging Area - A fenced area for equipment used for construction. 2. Railway right-of-way - only the section that is coincident with the proposed Atlantic Boulevard right-of-way plus an additional 10-feet where railroad/street traffic control devices must be relocated. 3. The entire right-of-way area for the intersection of Atlantic and District Boulevard demarcated by the fillet curves for the corners of the intersection.

Historical Resources Evaluation Report for Atlantic Boulevard Bridge over Los Angeles River i SUMMARY OF FINDINGS To enhance the safety of Atlantic Boulevard Bridge over the Los Angeles River (Br. No. 53C-0252) and improve intersection performance at District Boulevard, the City of Vernon proposes to widen Atlantic Boulevard from a point immediately north of the Los Angeles River to 800-feet south of the intersection of Atlantic Boulevard and District Boulevard. The project involves widening Atlantic Boulevard Bridge, and to provide lane widening, traffic shoulders, standard sidewalks, and a right turn lane associated with roadway located at the intersection of Atlantic Boulevard and District Boulevard. To accomplish bridge widening, the existing pier wall supports will be widened. In addition, debris nosing walls will be installed upstream of the bridge. Construction of the pier. widening and debris walls will include driving cast -in -place drilled hole (CIDH) piles into the riverbed. The improvement project will use federal funds and may affect historic properties (i.e., any prehistoric or historic site included on or considered eligible for inclusion on the National Register of Historic Places [NRHP]); therefore, it is considered a federal undertaking per 36 CFR 800.16(y) and subject to the authority of federal historic preservation law. Section 106 of the National Historic Preservation Act (NHPA) requires that federal agencies take. into account the effects of their actions on properties that are listed on, or eligible for listing on the NRHP. Additionally, a Programmatic Agreement was signed among the Federal Highway Administration, the Advisory Council on Historic Preservation, the California State Historic Preservation Officer, and the California Department. of Transportation, regarding compliance with Section 106, as it pertains to the Administration of the Federal -Aid Highway Program in California. This agreement supersedes the Section 106 regulations. The City of Vernon contracted URS Corporation (URS) to, conduct a cultural resources survey of the proposed Project site. In accordance with Section 106 of the NHPA, a historical architectural survey was completed for the project site on March 1, 2005 to identify historic properties that may lie within the study area. An evaluation of the built environment included the Atlantic Boulevard Bridge over Los Angeles River and one row of parcels abutting the east and west edges of Atlantic Boulevard, covering an area from one block south of District Boulevard northward to the 710 Freeway southbound onramp. URS identified two properties in the APE that required evaluation. These include, Seaside Oil Company (formerly Seaside Oil Company, established 1932), and Atlantic Boulevard Bridge over Los Angeles River (erected 1931). URS determined that neither of the properties appears to be eligible for listing on the National Register of Historic Places (NRHP). Similarly for the purposes of CEQA, the properties identified in the project area that were constructed before 1960 were determined not eligible for listing on the California Register of Historical Resources Historical Resources Evaluation Report for Atlantic Boulevard Bridge over Los Angeles River (CRHP). Also, as defined in Section 15064.5 of CEQA, the Project would result in no impact to cultural resources (the industrial buildings and associated outbuildings) because (a) the Project would not cause a substantial adverse change in the significance of a historical resource. M Historical Resources Evaluation Report for Atlantic Boulevard Bridge over Los Angeles River 2 PROJECT DESCRIPTION The Atlantic Boulevard Bridge Rehabilitation Project (Project) is located at the junction of the Atlantic Boulevard Bridge and Los Angeles River channel, approximately 0.25- miles south of the Interstate 710 Freeway, in the City of Vernon. The Project site includes the Atlantic Boulevard Bridge over the Los Angeles River, portions of Atlantic Boulevard north and south of District Boulevard, and easements and staging areas situated along the north and south banks of the river channel. The bridge is maintained by the City of Vernon. Refer to Map 1 for the Project Vicinity and Map 2 for the Project Location. The City of Vernon proposes to widen Atlantic Boulevard for approximately 1,300 linear feet to provide traffic shoulders, standard sidewalks, and a right turn lane over the Atlantic Boulevard Bridge over the Los Angeles River. The proposed roadway configuration includes six 11-foot through -traffic lanes, one 11-foot. right -turn lane, 4- foot minimum shoulders, and a median varying from 3-feet to-8 feet at District Boulevard... To accomplish the bridge widening, the pier wall supports will be widened approximately 16=feet to the west and 19-feet to the east. In addition, debris nosing walls will be installed upstream of the bridge, extending approximately 24-30 feet upriver. Construction of the pier widening and debris wall will include driving piles into the riverbed. The bridge widening will require additional easement right-of-way (ROW) from the Los Angeles County Flood Control District with the Los Angeles River. ROW will also be required from the Los Angeles Junction Railway (LAJRR) and the Los Angeles Department of Water and Power (LADWP). At the south end of the bridge, ROW easements will be taken at two properties on the east side of Atlantic Boulevard,. north and south of District Boulevard. The completed project will consist of a roadway and bridge that will provide a total of three northbound lanes, and three southbound through lanes and a right turn lane.. Sidewalks that are 5-feet in width (with subsurface excavations and base preparation approximately 18-inches below current grade) will also be constructed on each side of the bridge. The completed roadway and bridge will be in operation 24 hours -per -day, 7 days - .a -week. Total acres of project footprint (bridge work only) are estimated at 423-feet by 22.5-feet on the west side and 423-feet by 30-feet on the east side. Six debris walls will extend up to 24-30 feet upstream. Construction Methods To accomplish bridge widening, new piles will be drilled in -stream at both sides of the bridge to support the added lanes. Currently, there is a. total of six bents in -stream Historical Resources Evaluation Report for Atlantic Boulevard Bridge over Los Angeles River 1 supporting the bridge. These bents include a series of piles and are aligned parallel to the channel flow and at an angle to the centerline of the bridge and roadway spanning the Los Angeles River channel. Piles will be added to the west and east ends of each bent. In addition to the bridge foundation, debris walls with new foundations will be added on the upstream side. Construction will initially consist of pile installation and excavating and drilling of piles to support the bridge. Pre -cast, pre -stressed concrete piles will be used for debris walls in - stream and CIDH piles will be used at the bridge piers. The pre -cast piles will be brought to the site and driven into place without the need.to dewater at each location. The CIDH piles, pile caps, and deck widening will require concrete to be poured in steel or wooden forms. In this manner, no temporary structures will be constructed on the bottom of the channel. Bridge construction will require heavy equipment, such as a pile driver and crane for lifting deck beams. It is proposed that the nearby LADWP maintenance roads located on the northeast side of the Atlantic Boulevard Bridge over Los Angeles River be used as staging areas for construction material and equipment. The roadway portion of the bridge will involve typical -paving construction equipment. Historical Architectural APE The Area of Potential Effect (APE) boundaries were delineated in conjunction with the Caltrans PQS from CAD drawings for the proposed right-of-way as the basis for most of the affected area plus 2-feet along new sidewalks/curbs and 10-feet along the bridge span. Delineation has been included for two affected parcels: southeast corner of Atlantic and District Boulevard and northeast corner of Atlantic and District Boulevard. The former has a building on the site which will be and the utilities realigned as a separate project in agreement with the City of Vernon. The building will be demolished prior to beginning construction for the street widening task of the bridge widening project. There will be a required partial permanent taking in order to accommodate a right -turn pocket on the northbound side of Atlantic. Boulevard at the southern approach to the Atlantic/District Boulevard intersection. ,There will also be a required partial permanent taking of the parcel located at the northeast corner of Atlantic and District Boulevard to accommodate street widening on northbound Atlantic Boulevard approaching the widened bridge. Structures on this parcel will be left in -situ. Additional delineation has been included for the following: l . Staging Area- A fenced area for equipment used for construction. 2. Railway right-of-way - Only the section that is coincident with the proposed Atlantic Boulevard right-of-way plus additional 10-feet where railroad/street traffic control devices must be relocated. 3. The entire right-of-way area for the intersection of Atlantic and District Boulevard demarcated by the fillet curves for the corners of the intersection. Land uses within the historical architectural APE consist of industrial and commercial properties. Review of Los Angeles County Assessor's records and an intensive pedestrian Historical Resources Evaluation Report for Atlantic Boulevard ,Bridge over Los Angeles River survey by an architectural historian determined that there were two parcels within the APE requiring examination for potential historical significance. Upon further investigation URS identified two properties constructed before 1960. Table 1 lists the two properties identified in the architectural history APE that will be affected by the project. These properties were evaluated and determined ineligible for listing in the NRHP or CRHR.

Because the Project is also subject to the provisions of the California Environmental Quality Act of 1970 (CEQA), potential historic properties were identified and evaluated per the implementing regulations of the California Register of Historical Resources (CRHR) (CCR, Title 14, Chapter 11.5, Section 4852) Also, on behalf of the City of Vernon, URS requested a record search of the California Historical Resources Information System (CHRIS) be conducted by the South Coast Central Information Center (SCCIC), Cal State University Fullerton to determine previous cultural resources surveys, evaluations, and recordings within a 0.5-mile radius of the current Project. As part of the record search, the SCCIC reviewed the most current listings on the National Register of Historic Places (NRHP), the California Register of Historic Resources (CRHR), California Points of Interest, California Inventory of Historic Resources, and California State Historic Landmarks. Table 2 shows a Summary of Identification Efforts. In an effort to carry -out appropriate identification of potential archaeological resources, and facilitate public participation, URS contacted the Native American Heritage Commission (NAHC) to inform the commission of the proposed archeological survey, request information that might be listed in the Sacred Sites Index, and obtain a list of Native American organizations and individuals to be contacted regarding project plans and location. The record search undertaken by the NAHC failed to indicate the presence of Native American cultural resources in the immediate project area. The NAHC provided . a list of Native American organizations and individuals which may have knowledge of cultural resources within the project area. URS contacted these organizations and individuals by U.S. Mail (Appendix A). No responses were received in response to the mailing. URS reviewed parcel maps on file with the Los Angeles County Office of the Assessor, as well as historical maps (Sanborn Fire Insurance maps, USGS topographical maps, and Mexican Land Grant records) on file at the Los Angeles Public Library. Interviews with local property owners and reviews of historical narratives helped establish themes for a historical context of this study. Early 20th century industrialization and transportation were determined to be important contextual guides for the current City of Vernon study.

Pre -field research indicated that three parcels and the Atlantic Boulevard Bridge over Los Angeles River were situated within the APE for architectural history. Delineation has been included for two affected parcels: southeast corner of Atlantic and District Boulevard and northeast corner of Atlantic and District Boulevard. The former has a building on the site which will be demolished and the utilities realigned as a separate project in agreement with the City of Vernon prior to beginning construction for the street widening task of the bridge widening project. There will be a required partial permanent taking in order to accommodate a right -turn pocket on the northbound side of Atlantic Boulevard at the southern approach to the Atlantic/District Boulevard intersection. There will also be a required partial permanent taking of the parcel located. at the northeast corner of Atlantic and District Boulevard to accommodate street widening on northbound Atlantic Boulevard, approaching the widened bridge. Structures on this parcel will be left in -situ. Additional delineation has been included for the following: 1. Staging Area — A fenced area. for equipment used for construction. 2. Railway right-of-way — Only the section that is coincident with the proposed Atlantic Boulevard right-of-way plus an additional 10-feet where railroad/street traffic -control devices must be relocated. 3. The entire right-of-way area for the intersection of Atlantic and District Boulevard demarcated by the fillet curves for the corners of the intersection. On March 1, 2005, a senior scientist meeting the Secretary of the Interior's Qualification Standards (36 CFR 61) for architectural history, conducted an intensive pedestrian survey of the APE. Two buildings or structures constructed prior to 1960 were found within the APE; each was evaluated for historical significance. Evaluations of these properties were documented on DPR 523A and DPR 523B record forms. Each property was photographically recorded with a 35mm single lens reflex camera (Canon Elan 7) mounted with a 28mm wide-angle lens and using Kodak Gold 100 ASA color negative film. Photographs are included in the DPR 523 record forms found in Appendix A. Historical Resources Evaluation Report for Atlantic Boulevard Bridge over Los Angeles River 4 HISTORICAL OVERVIEW The study area is situated on former Mexican land grants known as the San Antonio Rancho and Rancho Laguna. In 1905, ranchers John B. Leonis, and James J. and Thomas J. Furlong purchased a 300-acre portion of the rancho lands and founded Vernon as an "exclusively industrial" city (Moruzzi 1997; Gumprecht 1997: 123). By the 1920s, major railroad companies such as the Santa Fe, Union Pacific, Southern Pacific, and Pacific Electric had built a network of transportation systems that connected the nation's major markets to southern California and thereby contributed greatly to the development of Vernon and neighboring Los Angeles communities. Beginning in 1923, investors working in partnership with the Santa Fe Railway Company developed the Central Manufacturing District, an area located in Vernon and bounded by Downey Avenue to the west, Atlantic Boulevard to the east, the Los Angeles River to the north, and Fruitland Avenue to the south. Until 1923, the area primarily consisted of agricultural lands and small truck farms. The Central Manufacturing District was patterned after a similar industrial/warehousing plan used in Chicago, which was at the time the largest, such district in the world. By 1929, Vernon's Central Manufacturing District had been transformed into a 2,800-acre industrial complex composed of stock yards, warehouses, and hundreds of manufacturing facilities. All combined, the district produced $30,000,000 in goods and freight annually, making it one of the most valuable industrial districts in the western U.S. (Gumprecht 1999: 122-123; Santa Fe 1929:21). By 1931 and the construction of the Atlantic Boulevard Bridge over Los Angeles River, the Central Manufacturing District had expanded along the southern banks of the Los Angeles River and eastward across Atlantic Boulevard. This expansion brought rise to properties that are subjects of this report, including the Seaside Oil Company (Los Angeles County Assessor 1991a; Sanborn Map Company: 1929-1949). The Central Manufacturing District was (and continues to be) serviced by the Los. Angeles Junction Railway, a Santa Fe -owned "short -line" rail system incorporated in 1923 to connect Vernon's manufacturing district to the freight transportation systems of the Pacific Electric, the Southern Pacific, as well as the shipping facilities located at the Port of Los Angeles (Santa Fe 1929:23-25). The Los Angeles Junction Railway today operates 64 miles of track, serving almost exclusively the City of Vernon's industrial and commercial zones. Sections of the railroad's main track and two spurs are visible in the study area. These consist of two sets of tracks that parallel the Los Angeles River, one set running on the river's north bank, and a second on the south bank; both are located in Vernon. Spurs (also known as service lines) lead from the main tracks and lead into properties situated within the study area (personal observation during field survey March 2005). As mentioned above, Atlantic Boulevard Bridge over Los Angeles River was constructed in 1931. Soon afterwards, under authorization of the Flood Control Act of 1936, the U.S. Army Corps of Engineers (USACE)' began channelizing (re -aligning, widening, and Historical Resources Evaluation Report for Atlantic Boulevard Bridge over Los Angeles River 7 lining with concrete) sections of the Los Angeles River, including the area next to the Atlantic Boulevard Bridge. By 1939, the river had been channelized from the San Fernando Valley to Olympic Boulevard (and the Olympic Boulevard Bridge, located about one mile north of our study area), and by about 1941, to Atlantic Boulevard and the study area. Because channelization required increasing the width and depth of the riverbed, the concrete piers of the Atlantic Boulevard Bridge were likely lengthened during this time to accommodate the resulting increase in distance from bridge deck to riverbed (Gumprecht 1999:115; 226-227). Today, Atlantic Boulevard Bridge over Los Angeles River serves as a conduit for approximately 60,000 trucks and automobiles that daily traverse Vernon's industrial district en route to or coming from the 710 Freeway. Over the decades, businesses in proximity to the bridge have come and gone, but traffic flowing through the area continues to grow. The City of Vernon hopes to facilitate the increases in traffic volume. Historical Resources Evaluation Report for Atlantic Boulevard Bridge over Los Angeles River S L 5 DESCRIPTION OF CULTURAL RESOURCES The study area is located in the City of Vernon, at the junction of Atlantic Boulevard and the Los Angeles River, approximately 0.25 miles south of the Interstate - 710 Freeway (I- 710). The study area is composed primarily of urban industrial and commercial properties, including operational and abandoned manufacturing facilities, a bulk oil transfer facility, wholesale warehouses, and active railroad tracks. Vacant lands belonging, to the Los ,Angeles Department of Water and Power abut the study area's northeast edge under a high -voltage transmission line corridor. A bike path runs parallel to the south bank of the Los Angeles River, traversing the southern portion of the study area. Residential units border the southeastern edge of the study area, and include single and multiple family dwellings. Units lying within the study area date to 1971, with neighboring dwellings (situated outside the study area) having construction dates as early as 1907 (Los Angeles County: 1991a, 1991b, 2000b, 2000c, 2004, & 2005). An evaluation of the built environment included the Atlantic Boulevard Bridge. over the Los Angeles River, and .parcels situated on Atlantic Boulevard between District Boulevard and the I-710 freeway, and one parcel on District Boulevard, south of Atlantic Boulevard. URS identified two properties in the study area that required further evaluation. These include Seaside Oil Company, established 1932, and the Atlantic Boulevard Bridge over Los Angeles River (erected 1931). The properties do not appear to be eligible for listing on the National Register of Historic Places (NRHP), and none qualify for listing on the California Register of Historic Resources (CRHR). Historical Resources Evaluation Report for Atlantic Boulevard Bridge over Los Angeles River 6 FINDINGS AND CONCLUSIONS On March 8, 2005, the South Central Coastal Information Center at Cal State University Fullerton reported that no historic resources have been identified within a 0.5-mile radius of the project site. On March 1 and March 7, 2005, URS conducted field evaluations of the built environment. URS identified two properties in the study area that required further evaluation. These include Seaside Oil Company established 1932, and the Atlantic Boulevard Bridge over Los Angeles River (erected 1931). Table 3 provides a list of these properties. Narrative descriptions follow below. Neither of the evaluated properties appears to be eligible for listing on the National Register of Historic Places: In 1986, Caltrans evaluated the Atlantic Boulevard Bridge over Los Angeles River and listed it as a category "5," "not eligible for the NRHP. The bridge was re-evaluated for this study and found to be lacking in some of its original design and material elements (including light standards). This bridge was found to be less exceptional architecturally than other nearby Los Angeles River bridges (such as those at Washington and Olympic Boulevards) and therefore does not appear to be eligible. 2. The former Seaside Oil Company building lacks integrity of design, materials, and setting and therefore does not appear to be eligible. Similarly, for the purposes of CEQA, the properties identified in the project area that were constructed before 1960 do not appear to be eligible for listing on the CRHR. Also, as defined in. Section 15064.5 of CEQA, the Project would result in no impact to cultural resources (the industrial buildings. and associated outbuildings) because (a) the Project would not cause a substantial adverse change in the significance of a historical resource.

Include design, materials, condition, alterations, size, setting, and boundaries) The subject structure is a concrete multiple arch bridge 422 ft. long by 66 ft. wide, constructed in 1931 by the County of Los Angeles Road Department. Known today as the Atlantic Boulevard Bridge over Los Angeles River, the structure consists of a Neo- Classical design, with seven, closed -spandrel arches supported by six concrete piers and two concrete abutments. Pier footings are approximately 27 ft. by 70 ft. in plan dimension, and supported by approximately 115 driven piles per footing. Each abutment rests on 138 piles. Abutment footings are approximately 16 ft. by 70 ft. in plan, and the bottoms are inclined. The piles depicted in the 1931 as-builts indicate that they are 16-in. square driven concrete piles. The pile lengths for the piers ranges from 24 to 27 ft., and the pile lengths for the abutments are 24.5 ft. Deck is reinforced concrete. Rails and panels are reinforced concrete. Original light standards have been replaced by steel pole, mercury vapor lamps. Setting is the northeast edge of the former City of Vernon Central Manufacturing District which is today zoned Industrial. South end of bridge lies adjacent to intersection of S. Atlantic Boulevard and District Boulevard; north end of bridge leads to 710 Freeway located 0.25 miles north. The tracks of the Los Angeles Junction Railway cross approximately 20 ft. north and south of bridge ends. Channelized Los Angeles River crosses under the bridge. *P3b.

Also address integrity.) By the 1920s, major railroad companies such as the Santa Fe, Union Pacific, Southern Pacific, and Pacific Electric had built a network of transportation systems that connected the nation's major markets to Vernon and neighboring Los Angeles communities. Beginning in 1923, investors working in partnership with the Santa Fe Railway Company developed the Central Manufacturing District, an area located in Vernon and bounded by Downey Avenue to the west, Atlantic Boulevard to the east, the Los Angeles River to the north, and Fruitland Avenue to the south. Until 1923, the area primarily consisted of agricultural lands and small truck farms. The Central Manufacturing District was patterned after a similar industrial/warehousing plan used in Chicago, which was at the time the largest such district in the world. By 1929, Vernon's Central Manufacturing District had been transformed into a 2,800- acre industrial complex composed of stock yards, warehouses, and hundreds of manufacturing facilities. All combined, the district produced $30,000,000 in goods and freight annually, making it one of the most valuable industrial districts in the western U.S. (Gumprecht 1999: 122-123; Santa Fe 1929:21). The construction of the Atlantic Avenue Bridge over Los Angeles River facilitated the eastward expansion of the Central Manufacturing District by providing access to vicinity industry and markets elsewhere in California and the nation. The subject structure was evaluated by Caltrans in 1986 and listed on the Historic Bridge Inventory as a category "5" not eligible for listing on the NRHP. The status remains unchanged. The subject has lost some integrity of design and materials with the replacement of original light standards. More importantly, the subject was designed more as. a utilitarian structure, without embellishment, and more or less of common design, for industrial L.A. than as part of the Bridge Beautiful structures constructed with more detail and aesthetic on the L.A. River at such locations as Olympic and Washington Boulevards. The Atlantic Boulevard Bridge over Los Angeles River does not appear eligible for listing on the NRHP. B11.

By providing oil and gasoline to the area industries, bulk oil storage and transfer facilities such as the subject property (former Seaside Oil Co.) both contributed to the industrialization of southern California and profited from the growth of manufacturing which occurred in the Central Manufacturing District.

ATLANTIC BOULEVARD VERNON CA The subject property was erected in 1931-1932 as a bulk plant known as Seaside Oil Company. Seaside Oil Co. incorporated in 1898, founded by John B. Cook and five San Francisco area investors. Seaside operated until 1943, when J. Paul Getty's Tidewater Associated Oil Company bought controlling shares of Seaside. In 1966, Seaside Oil Co. (then a subsidiary of Tidewater) was along with Tidewater Associated bought out by Phillips Petroleum Company. In 1983, current owner P. Gorzman bought the property and incorporated under the name Oil Service, Inc. The Oil Service, Inc. compay has operated continuously to current time (March 2005). The subject property was formerly serviced by the Los Angeles Junction Railway spur running along the oil company's north boundary. Today, tanker trucks haul oil to the location from the Port of Los Angeles. The former Seaside Oil Co. bulk oil plant is not eligible for listing on the NRHP because much of its historic fabric has been compromised: Original storage tanks have been replaced, the current loading rack replaced original, the office building has lost integrity of materials (stucco has replaced original wood siding, fenestrations have been removed and boarded -up), and a shed addition have changed original design of garage.

APPENDIX B Memorandum Atlantic Boulevard Bridge Over The Los Angeles River (Bridge No. 53C-252) Vernon, CA 29401915.00001 TO: Dan Weddell (WKA) by Email FROM: Michael Smith, GE, Farid Motamed, P.E., Chris Goetz, C.E.G. _V DATE: June 4, 2004 SUBJECT:, Draft Preliminary Foundation Report Site Location 2020 East First Street Suite 400 Santa Ana, CA 92705 Tel - (714) 835-6886 Fax - (714) 667-7147 farid—motamed@urscorp.com orp.com The site is located at Atlantic Boulevard and the Los Angeles River in Vernon, California as shown on Figure 1. The site's coordinates are 118.1820 W, 33.995° N. According to the "as -built" drawings (County of Los Angeles Road Department, 1930-31), the original ground elevation at the site was approximately 150 ft. Site Geology and Subsurface Conditions The project site is located in the southwestern portion of the Los Angeles basin. This area is located within the Peninsular Ranges Geomorphic Province, which is characterized by generally northwest trending ridges and intervening basins. The Los Angeles basin is a structural depression in which a thick sequence of marine sediments f and alluvium has accumulated since latest Miocene time. In the near surface, the site is underlain by upper Pleistocene to Holocene alluvial deposits associated with the flood plain of the Los Angeles River. The California Geological Survey (CDMG, 1998), formerly known as the California Division of Mines and Geology, mapped the alluvium beneath the site as younger Quaternary alluvium consisting predominantly of loose to medium dense coarse to very fine grained sand, gravel and silt. Historically highest groundwater, as reported by the California Geological Survey (CDMG, 1998) is about 17 feet below the street level surface. The "as -built" drawings (County of Los Angeles Road Department, 1930-31) do.not have logs of test borings. The drawings do, however, have an interpretive geologic profile that indicates the site is underlain by alternating layers r of sand and clay from the ground surface at that time (approximately El. 151 feet) to the depth of the interpreted profile (about El. 100 feet). The interpretive geologic profile indicates a water table between Elevation 135 and 150 feet which corresponds to about 10 feet above to 5 feet below the current LA river channel bottom. The consistency i of the soils is not indicated other than a layer below Elevation 120 feet is described as "hard pan". As it will be Preliminary Geotechnical Memorandum Atlantic Blvd Bridge Over the Los Angeles River Vernon, California 29401915.00001 June 4, 2004 discussed in this memo, we have assumed properties of the soils in our analyses that are consistent with young alluvial deposits that would be typically encountered in this area and are consistent with the information available. As Built Data The as -built data indicate the existing bridge is supported on six piers (Pier 1 through 6) and two abutments (North and South Abutment). The bottom of the pier footings is approximately elevation 134 feet. The pier footings are approximately 27 feet by 70 feet in plan dimension and supported by approximately 115 driven piles per footing. The abutments footings are also at about elevation 134 feet and supported by approximately 138 piles per footing. The abutment footings are approximately 16 by 70 feet in plan and the bottoms are inclined. The piles for both the piers and abutments are depicted on the plans as 16-inch square driven concrete piles. The pile tip elevations for the piers ranges from 107 to 110 feet and the pile tip elevations for the abutments is 109.5 feet. The pile lengths for the piers ranges from 24 to 27 feet and the pile lengths for the abutments are 24.5 feet. It is our understanding that the bridge structure is concrete with soil in fill. The river channel is lined in the area of the bridge. Seismicity and Faulting Based on the California Seismic Hazard Map (Caltrans, 1996) as shown on Figure 2, several significant faults surround the subject site. These include the Elysian Park Seismic Zone (EPK), Newport -Inglewood (NIE), Whittier -Elsinore (WEE), Malibu Coast -Santa Monica -Hollywood -Raymond (MMR), Chamock (CNK), Eagle Rock (ERK), Los Alamitos (LAO), San Femando-Sierra Madre -Duarte (SSD), Palos Verdes (PVS), San Jose (SJE), San Gabriel (SGL), El Modeno-Peralta Hills (EMP), Simi -Santa Rosa -Northridge (SSD) and San Andreas/C (SAC). Fault parameters and distances are presented in the following table. Elysian Park Seismic Zone 7 4 Reverse Newport -Inglewood 7 12 Strike -Slip Whittier -Elsinore 7 1/2 13 Strike Slip Malibu Coast -Santa Monica -Hollywood -Raymond 7 1/2 14 Reverse - Oblique Chamock 6 1/2 17 Strike -Slip Eagle Rock 6 17 Unknown Los Alamitos 6 17 Unknown San Fernando -Sierra Madre -Duarte 7 1/2 23 Reverse Palos Verdes 7 26 Strike-Slip San Jose 6 3/4 25 Reverse San Gabriel 7 1/2 31 Reverse -Oblique El Modeno-Peralta Hills 6 1/2 33 Unknown Simi -Santa Rosa -Northridge Hills 7.5 38 Reverse -Oblique San Andreas SAC 8.0 59 Strike-Sli 'Obtained from California Seismic Hazard Map (Caltrans, 1996) Seismic Parameters and ARS Curve e Based on the California Seismic Hazard Map, the controlling earthquake is a magnitude of 7.0 on the Elysian Park Seismic Zone, resulting in peak horizontal bedrock. acceleration (PBA) of 0.5 g (units of gravity) at this site. For developing seismic spectra using Caltrans Seismic Design Criteria Version 1.2 (December 2001) (Caltrans SDC 1.2), the seismic parameters below may be used: Preliminary Geotechnical Memorandum Atlantic Blvd Bridge Over. the Los Angeles River Vernon, California 29401915.00001 June 4, 2004 Peak Rock Acceleration (g) 0.5g Soil Profile Type (As per SDC 1.2) D Maximum Credible Event Magnitude 7.0 (t 0.25) This curve is presented in the Caltrans SDC 1.2 in Figure B-8. Since the structure is within 15 kilometers of active faults, the spectral acceleration should be modified as per Caltrans SDC 1.2. The resulting response spectrum is presented in Figure 3 and Table 1. Caltrans Guidelines for Foundation Investigations and Reports Version 1.2 (June 2002) recommends that the acceleration from the Caltrans California Seismic Hazard Map and Report 1996 (Caltrans, 1996) be verified with a well -established attenuation relationship. To do this, we calculated the peak horizontal acceleration and acceleration response spectra for the site using the attenuation relationships from Sadigh et al (1997) for soil sites. The Sadigh relationship also includes style of faulting. The response spectrum was also modified for distance to fault in the same manner as the Caltrans spectra. The results of this are presented on Figure 3 and in Table 2. We recommend the Sadigh Spectra be used to perform preliminary analysis of the structure. Liquefaction Because of the generally shallow depth of historically high groundwater (— the current channel bottom) and the generally unconsolidated nature of the Late Holocene deposits, the potential for soil liquefaction during an earthquake is considered moderate to high at the site. The California Geological Survey (CDMG, 1998) has mapped the site as being within a Liquefaction Hazard Zone. That is, the site is within an area where there has been an historic occurrence of liquefaction or where local geologic, geotechnical, and groundwater conditions indicate a potential for liquefaction. The precise depth and extent of liquefaction potential will need to be evaluated during the final geotechnical investigation for the project. Scour The Los Angeles River channel is lined in the area of the bridge and therefore the potential for scour is considered very low. Corrosion There is no corrosion data available at this time on the subsurface soils at the site. Samples should be collected during the final design geotechnical investigation and tested in accordance with the Caltrans Corrosion Guidelines latest version. Preliminary Evaluation of Stiffness and Capacity of Existing Foundations Soil Parameters We assumed the following parameters in our analyses based on the limited information available and our judgment: Soil Type: Sand Friction Angle: 33 to 38 degrees Cohesion: zero Unit Weight: I IS tol20 pcf Poisson's Ratio: 0.45 Shear Modulus:13 ksi Young's Modulus: 38 ksi We also assumed that the groundwater was at the channel bottom. Preliminary Geotechnical Memorandum Atlantic Blvd Bridge Over the Los Angeles River Vernon, California 29401915.00001 June 4, 2004 These parameters were used to develop foundation stiffness parameters (Foundation Springs) and to evaluate the lateral and axial capacity of the exiting piles. Foundation Springs We developed foundation springs using the soil parameters described above. The soil stiffness coefficients (spring constants) for vertical and lateral translation and the capping displacement for each are presented in Table 3. Capacity of Existing Foundations We have performed axial pile capacity analysis for the existing piles. We estimate that the existing piles have an axial capacity in compression of 45 tons (Service State) and 90 tons (Nominal Compression). One half these values may be assumed for uplift capacity. We have also performed a. lateral analysis of the existing pile foundations using the p-y analysis methodology. We performed the analysis assuming the following: 16 inch square concrete piles 27 foot long piles I mcked = 0.6 I grm Bottom of footing 134.0 feet Pile tip elevation 107.0 feet Pile spacing 2.75 feet Pile Group Effect was included in analysis.

The maximum moments were -34 and +10.5 k-feet for the fixed head case. 1 Lateral Earth Pressures for Analysis of Bridge For design purposes, a triangular distribution of lateral earth pressures with an equivalent fluid pressure of 55. pounds per cubic foot (pcf) should be used in design of walls for a restrained condition where walls are fixed against rotation at the top and bottom. For design of cantilever walls where rotation about the bottom of the walls below grade is permitted, a triangular distribution of lateral earth pressures with an equivalent fluid pressure of 35 pcf should be used in design of walls below grade. Surcharge pressures (dead or live) should be added to the above lateral earth pressures where surcharge loads may be located adjacent to the wall. Surcharge pressures should be applied as a uniform (rectangular) pressure . distribution by using a lateral earth pressure coefficient of 0.45 for restrained walls and 0.3 for walls permitted to rotate. Vertical surcharges setback behind the wall a horizontal distance greater than the wall height need not be added the design pressure. The above coefficients assume a uniform surcharge load. Specific recommendations can be provided for point, line or other loading conditions. Total lateral earth pressures acting on the wall during a seismic event will likely include the static force and the dynamic increment. Using the Mononobe-Okabe procedure, a dynamic lateral earth pressure increment (for a 0.58g PGA condition) of 20H (in unit of psf) may be assumed for design purposes for restrained walls and 13H for walls permitted to rotate, where H (in unit of feet) is the height of the wall. This dynamic increment should be applied to the wall as a uniform pressure over the entire wall height. The lateral earth pressures recommended above are based upon the assumption that the backfill is granular, the ground surface behind the wall is level, and the wall backfill is well drained. Preliminary Discussion of Foundation Type for Widening It is our opinion that the bridge widening can be supported on either precast driven concrete piles for concrete filled steel pipe piles, depending on the extent and impact of liquefaction potential. For 70 to 100 ton axial capacity piles = (service state) the piles would be on the order of 50 to 70 feet long. A final foundation investigation should be performed to determine the final pile type and depth. References California Department of Conservation Division of Mines and Geology (1998).

The proposed project is located within Township 2 South, Range 12 West, Section 18 as depicted on the South Gate, California USGS 7.5 Minute Series Topographic Quadrangle Map. The project area begins north of District Boulevard and extends north-eastward along Atlantic Boulevard, crossing over the Los Angeles River and ends near the railroad tracks on the north side of the river.. Regionally, the site lies south/southwest of the Long Beach Freeway (1-710) and the Santa Ana Freeway (I-5) interchange, and is completely surrounded by industrialized land uses. 1.1 Physical Features The project involves widening and rehabilitating the Atlantic Boulevard Bridge (Bridge No. 53C-0252). The purpose is to upgrade the safety of the bridge and enhance its use to the public by widening the bridge on both sides. To accomplish this widening, new piles will need to be added to both sides of the bridge in support of the widened lanes. Currently, there are a total of six piers in -stream supporting the bridge. These piers comprise a series of piles and are aligned parallel to the channel flow and at an angle to the centerline of the bridge and roadway spanning the channel. To each of these piers, Class 100 driven steel pipe piles filled with concrete will be added on both sides of each pier. New Class 40 concrete piles _ will be added on the upstream side to support the debris walls. The widening and bridge expansion will remain within the existing local jurisdictional right-of-way. The Los Angeles County Flood Control District also maintains a right-of-way of the Los Angeles River across which the project will be constructed. The width of the channel from bank to bank is approximately 423-feet. 1.2 Operational Features The completed project will consist of a roadway and bridge that will provide a total of three northbound lanes and four southbound lanes that include a southbound right -turn lane. Four -feet wide shoulders and a five-foot wide sidewalk will also be constructed on both sides of the roadway. The completed roadway and bridge will be in operation 24 hours a day, seven days a week. 1.3 Construction Operations To accomplish this bridge widening, new piles will be driven in -stream at both sides of the bridge to support the added lanes. Currently,. there is a total of six piers in -stream supporting the bridge. These piers comprise a series of piles and are aligned parallel to the channel flow and at an angle to the centerline of the bridge and roadway spanning the channel. To each of these ` piers, additional Class 100 driven steel Pe i piles filled with concrete will be added on both sides P of each pier. Construction will initially consist of pile driving and excavating and drilling of k 2 piles to support the bridge. The piles will be brought to the site and driven into place without the need to de -water at each location. The piles, pile caps, and deck widening will require poured concrete in steel or wooden forms. In this manner, no temporary structures will be constructed on the bottom of the channel. Bridge construction will require heavy equipment, such as a pile driver and crane for lifting the deck beams. Pile driving within the channel will occur from the existing bridge and from work barges or platforms. It is possible that the Los Angeles County Flood Control District (LACFCD) maintenance roads may be used as staging areas for construction material and equipment. A 14 months construction duration .is anticipated. 2.0 Description of Watershed Characteristics 2.1 Los Angeles River, Tributaries, Groundwater Basins The Los Angeles River is located within the north -central portion of the Los Angeles Basin. The Los Angeles and Long Beach Harbors are located approximately 15 miles downstream along the Los Angeles River. Physiographic features of the greater Los Angeles Basin area include numerous washes to the west of the project site and the eastern edge of the Rosecrans Hills to the southwest. Historically, the area consisted of the flood plain of the Los Angeles River. Flow from the San Fernando Groundwater Basin enters the Los Angeles Central Basin through the Los Angeles Narrows, located northwest of the project site. The Los Angeles Narrows is a small valley at the eastern edge of the Santa Monica Mountains bounded by the Elysian Hills and Repetto Hills. The Los Angeles River was channeled and concrete lined in the 1950s and 1960s. The Los Angeles River is an approximately 50-mile long channelized concrete drain serving a watershed that includes parts of the San Fernando Valley, and the cities of Los Angeles, Vernon, _> Maywood, Bell, Bell, Gardens, Cudahy, Downey, South Gate, Huntington Park, Lynwood, Paramount, Compton, and Long Beach, California. It lies within the West Coast Groundwater Basin and has no tributaries. Other channelized drains send storm water runoff into the Los b Angeles River, including the Bell Creek, Verdugo Wash, Tujunga Wash, Arroyo Seco and Compton Creek. 2.2 Climate, Rainfall The Los Angeles Basin enjoys a Mediterranean -style climate. The climate is warm and dry throughout much of the year with rainfall generally occurring in the months of December through March. Average rainfall is 12 to 14 inches annually. 2.3 Hydrology, Drainage The Los Angeles River is an approximately 50 mile long channelized drain serving a watershed that includes the San Fernando Valley and parts of the cities of Los Angeles, Vernon, Maywood, Bell, Bell Gardens, Cudahy, Downey, South Gate, Huntington Park, Lynwood, Paramount, Compton, and Long Beach. It lies within the West Coast Groundwater Basin and has no tributaries. It lies within the West Coast Groundwater Basin and has no tributaries. Other 9 channelized drains send stone water runoff into the Los Angeles River, including the Bell Creek, Verdugo Wash, Tujunga Wash, Arroyo Seco and Compton Creek, California. Runoff/drainage generally occurs during the winter months. However, there are. many industries upstream that discharge polluted wastewater into the channel. All water flowing in to the channel is discharged into the Long Beach Harbor. 3.0 Applicable Water Quality Plans and Policies 3.1 Federal Plans and Policies The U.S. Army Corps of Engineers (ACOE) regulates the discharge of dredge or fill material to "Waters of the U.S." under Section 404 of the Clean Water Act. Los Angeles River has a defined bed and bank, and a defined "ordinary high water mark." The portions of this stream within the, ordinary high water marks are considered "Waters of the U.S." Any discharge of.fill material within the ordinary high water marks of these streams will require a permit from the ACOE. The bridge widening of Atlantic Boulevard over Los Angeles River may require a Section 404 permit from the Army Corps of Engineers (nationwide permit). 3.2 State Plans and Policies A Section 401 Certification from the Regional Water Quality Control Board (RWQCB) will be required. This certification states that the project will meet applicable water quality objectives set forth in the Water Quality Control Plan, Los Angeles Region (1994) and applicable provisions of the Clean Water Act. Under section 1601 of the Fish and Game Code, before any State or local governmental agency or public utility begins a construction project that will: 1) divert, obstruct, or change the natural flow or the bed, channel, or bank of any river, stream, or lake; 2) use materials from a streambed; or 3) result in the disposal or deposition of debris, waste, or other material containing crumbled, flaked, or ground pavement where it can pass into any river, stream, or lake, it must first notify the California Department of Fish and Game of the proposed project. Notification is generally required for any project that will take place in or in the vicinity of a river, stream, lake, or their tributaries. This includes rivers or streams that flow at least periodically or permanently thr ough a bed or channel with banks that support fish or other aquatic life and watercourses having a surface or subsurface flow that support or have supported riparian vegetation. In order to notify the Department of a project described above, the person, governmental agency, or public utility (applicant) needs to complete the Notification of Lake or Streambed Alteration form (FG 2023) and Project Questionnaire form (FG 2024) and submit these forms, along with any other required documents and applicable fees to the Department. Based on the notification materials submitted to the Department and, if necessary, an investigation of the project site by the Department, the Department will determine if the proposed project may impact fish or wildlife resources. If the Department determines that the proposed project may substantially adversely affect existing fish or wildlife resources, the City will need to obtain a Streambed Alteration Agreement from the Department and the proposed project, unless it is otherwise exempt,, will have to be reviewed in accordance with the California s 4 Environmental Quality Act (CEQA) (Pub. Resources Code, § 21000 et seq.) before any work may begin. The State's general permit for discharges of storm water from construction activities requires the site owner to apply with the State, to prepare and implement a Storm Water Pollution Prevention Plan, and to monitor the effectiveness of the plan. The plan does not have to be submitted to the Regional Board, but must be on site and available to inspectors. The plan must also address post - construction control of pollutants in storm water. 3.3 Local Plans and Policies The proposed project will be required to be in compliance with applicable City of Vernon grading and stormwater management requirements. 4.0 Beneficial Uses and Water Quality Objectives of Los Angeles River and Tributaries The portion of Los Angeles River at the project site is a concrete channel in nature and has been designated for.the following existing or potential beneficial uses: • Contact and noncontact water recreation ' • Preservation of rare and P endangered species g • Industrial water supply • Navigation Commercial and sport fishing p rt slung • Marine habitat • Estuarine habitat • Wildlife habitat • Migratory and spawning habitat 5.0 Existing Water Quality of Los Angeles River 5.1 Summary of Available Water Quality Data The available water quality data indicates that due to the location within a highly industrialized area, discharge of secondary treated effluent from a POTW, discharge from generating stations, discharge from refineries, and discharge from smaller, non -process waste discharges, the Los t Angeles River has very poor water quality. The data indicate that the water and/or sediment is impaired by PCBs, PAHs, historic pesticides, coliform bacteria, trash, elevated nitrogen, historic deposits of DDT and PCBs in sediment. Other factors affecting water quality include discharges s, and spills from refineries and ships, stormwater runoff, contaminated groundwater, POTW discharges, and construction runoff. 5 5.2 Water Quality Impairments and the Status of TMDLs Pollutants listed on the 303(d) list for the Los Angeles River include: chlordane, DDT, PCBs, aldrin, dieldrin, PAHs, copper, lead, chromium, zinc, nitrogen, ammonia. The benthic communities are listed as impaired. The Regional Water Quality Control Board, Los Angeles z Region is in the process of determining TMDLs. 6.0 Storm Water Runoff from the Project 6.1 Project Drainage Features Current project drainage consists of runoff from the existing bridge structure, existing roadway, existing bicycle path, and existing sidewalk. During the project phase, nuisance runoff will need to be prevented. 6.2 Potential Storm Water Pollutants (Construction and Operational Phase) Potential storm water pollutants deriving from the construction phase may consist of: earth and other construction -related materials, construction materials such as concrete, trash, and equipment fluids. Potential storm water pollutants during the operational phase may consist of street runoff, trash, and upgradient pollution sources. 6 7.0 Potential Impacts on Water Quality and Beneficial Uses of Los Angeles River and Tributaries 7.1 Threshold of Significance Water quality impacts are expected to be temporary. Sediments impacted by the pollutants listed above are likely to be disturbed during the pile driving phase of the project. 7.2 Impact Discussion Water quality impacts during construction will be temporary and will primarily consist of disturbance of already -contaminated Los Angeles River sediments during in -channel pile driving. These disturbed sediments are expected to have a less than significant impact on water, quality for the following reasons: Sediments will only be disturbed in the immediate vicinity of the entry point for each pile; and Due to the normally sluggish nature of currents in this portion of Los Angeles River, the disturbed sediments are expected to settle back to the bottom of the channel only a short distance from where the disturbance took place. Other potential impacts include releases of minor potential storm water pollutants deriving from the construction phase consisting of: earth and other construction -related materials, construction materials such as concrete, trash, and equipment fluids. Potential storm water pollutants during the operational phase may consist of street runoff, trash, and upgradient pollution sources.' Application of the following Mitigation Measures/Best Management Practices will reduce these impacts to less than significant levels. 8.0 Mitigation Measures/Best Management Practices The project should implement several Best Management Practices, including, but not limited to, the following: • Pile driving operations will take place during seasons of low flow. • Construction equipment shall be properly maintained to prevent pollution from entering the channel. • Sandbags placed at an appropriate distance downstream from the construction site to create a retention basin for collecting any possible discharge water and construction materials. This measure is particularly applicable to the areas of the bridge abutments. Anything collected should be properly disposed at the end of each day. • Stockpiles of earth and other construction related materials should be protected from being transported from the site by wind or water. • Excess or. waste concrete will not be washed into the channel or any drainage system. L- 7 • Excess or waste concrete will be retained onsite and disposed of properly or recycled. • Trash and construction -related wastes shall be deposited into a covered receptacle to prevent contamination of rainwater and dispersal by wind. • Good housekeeping practices at the construction site such as dust control, site perimeter control and clean-up at the site on a daily basis is required. • Erosion control techniques such as silt fences, hay bales, and sand bags will be used. 0 APPENDIX.D ■ Z M r I' 1-4 l� To: From: Date: Subject: Dan Weddell, Wei Koo Associates David Madera, EIT Keith Rand, P.E.

The traffic analysis was performed to support the Project Report (PR) and the associated environmental assessments required for the project. Existing 2004, future Year 2020, and future Year 2030 with and without improvements were analyzed for the AM and PM peak hours. Existing traffic count data was collected in May 2004 by Southland Car Counters. The data collection efforts included both Average Daily Traffic (ADT) tube counts and peak hour turning movement counts within the study area surrounding the intersection of Atlantic Boulevard at District Boulevard. The peak hour turning movements counts were collected with truck classification by axle (2, 3, 4, and 5+). Table 1 summarizes the raw data collected during the AM (7:00 — 9:00 a.m.), Midday (11:00 a.m. — 1:00 p.m.), and PM (4:00 — 6:00 p.m.) counts. The truck classifications were then utilized to calculate passenger car equivalent volumes for both the turning movement counts and the ADT volumes. A growth rate of one (1) percent per year was applied to the modified existing volumes to calculate the future year demand projections. The percentage of trucks was assumed to be the same.

The measures of effectiveness (MOEs) are queue lengths, overall intersection delay (seconds per vehicle) and the intersection level of service (LOS), were used to help identify potential improvements within the study area and for the intersection of Atlantic Boulevard. with District Boulevard. Field investigations indicated that the heavy truck movements, particularly the WB-40 type (5 axle trucks), were constrained by the current geometry of the roadway. For example, the trucks making the southbound right (SBR) onto District Boulevard from Atlantic Boulevard start their turn in the outer most southbound through (SBT) lane in the southbound direction and then travel across the outside lane of District Boulevard to the second lane from the right. Thus, the "free" SBR movement is actually restricted by the SBT and westbound through (WBT) movements. Based on this field review and the initial traffic analysis using the existing geometric conditions, it was determined that the traffic model with existing geometrics needed to be modified to mimic the real world conditions. The analysis reflects field conditions with heavy truck movements, which is more restrictive than conventional input of the geometry. For instance, the SBR pocket was reduced from 140' to 30', which is the clearance of the "pork -chop island" on the northeast side of the intersection. Further, the movement was restricted during the westbound split phasing versus being modeled as a "free" right turn movement. In consultation with City staff, it was recommended that a cycle length of 90 seconds be used in the traffic analysis. The 90-second cycle length was applied to Existing and Year 2020 conditions.

The existing and future base conditions assumed existing geometries remained the same, with 3 lanes in each direction g with a short dedicated SBL and. SBR lanes at the intersection. Existing Mitigation for SB Atlantic Boulevard at District Boulevard Existing mitigated scenario proposes the conversion of the outermost southbound through (SBT) lane to extend and widen the existing southbound right..(SBR) turn lane at the intersection of Atlantic Boulevard and District Boulevard, with no bridge improvements. This reconfiguration will enhance the southbound right (SBR) turn movement and in particular, facilitate the turning of longer trucks. This mitigation also provides an opportunity to modify the existing operations of the eastbound right (EBR) turn movement from stop controlled to "free," where the vehicles turning right onto southbound Atlantic Boulevard are provided an unrestricted lane and are not required to stop ' prior to turning right. However, this will require the existing "pork -chop islands" to be redesigned. Alternative 1 Future year 2020 and .2030 with project Alternative 1 assumed the widening the Atlantic Boulevard Bridge across the Los Angeles River to standard lane width. At the intersection of Atlantic Boulevard with District Boulevard, Alternative 1 proposes the conversion of the outermost southbound through (SBT) lane to extend and widen the existing SBR turn lane. This reconfiguration will enhance the southbound right (SBR) turn movements and in particular, facilitate the turning of longer trucks. Alternative 1 also provides an opportunity to modify the future operations of the eastbound right .h (EBR) turn movement from stop controlled to "free," where the vehicles turning right onto southbound Atlantic Boulevard are provided an unrestricted lane and are not required to stop prior to turning right. However, this will require the existing "pork -chop islands" to be redesigned. Alternatives 2 Project Alternatives 2 assume the widening of the Atlantic Boulevard Bridge across the Los Angeles River to standard widths for six through lanes plus the addition of one dedicated southbound right (SBR) turn lane leading to the existing southbound right (SBR) turn lane at the intersection of Atlantic Boulevard with District Boulevard. It is assumed that there will be no lane reductions at the intersection, as the existing lane configuration of the southbound Atlantic Boulevard approach will be maintained at its current configuration of one left turn lane, three through lanes and one dedicated right turn lane. 1 Table 2 below illustrates the queue lengths of each movement based on the Synchro analysis. The analysis also assumed the southbound right (SBR) turn movement was "free" except during GAPLANNING MISIOMVERNOMMEMORANDUM-trafc 03-29-2005.doc lob No. 29401915 Atlantic Blvd. Bridge Improvements Traffic Findings Page 4 the westbound split phase, when all westbound traffic movements go at the same time. The southbound right (SBR) movement was analyzed as permissive with overlap (PM-OV) phasing, a which means. southbound right turns are allowed during the eastbound left turn phase of the cross street allowing for "overlap" in addition to the southbound green signal indication.

The "pork -chop islands" on the west side of p P the roadway would both be pushed out into the outer most southbound lane. The resulting widened. SBR pocket and outer most southbound lane would need to be re -striped in order to channel the long trucks smoothlyaround the northwest comer, with the remainder of the pocket � hatched to minimize driver confusion. G:tPLANNINGDIVISIOMVERNOMMEMORANDUM-traffic 03-29-2005.doc Job No. 29401915 Atlantic Blvd. Bridge Improvements Traffic Findings Page 5 Mitigated project Alternative 1 would provide both operational and safety improvements to the intersection, especially for long trucks turning right onto District Boulevard from southbound Atlantic Boulevard. Mitigated project Alternatives 2 also. provide operational and safety improvements to the intersection of Atlantic Boulevard with District Boulevard in all future year scenarios by adding a dedicated SBR turn lane across the bridge.. In addition, mitigated project Alternatives 2 provides improved LOS. as compared to both the base and mitigated Alternative 1 scenarios. It is recommended that the mitigated project Alternatives 2 be implemented based on the traffic operational performance. The overall LOS for'all project Alternatives 2 scenarios is LOS D, whereas the base and mitigated project Alternative 1 scenarios become oversaturated resulting in LOS E or F conditions.. Further, it is recommended that an advanced pedestrian safety device be provided for pedestrians crossing the free SBR movement at Atlantic Boulevard at District Boulevard. Project Construction Analysis During project construction, the eastside of the bridge will be narrowed to two northbound through lanes. Currently the bridge provides for 3-lanes each for both northbound and southbound direction. While the east half of bridge is under construction and narrowed to 2- lanes, it is necessary that one of the three northbound through lanes at the intersection of Atlantic Boulevard need to be temporarily terminated and converted to an exclusive right turn to eastbound District Boulevard. Table 3 below summarizes the traffic analysis conducted for both pre -construction and with construction conditions. For analysis purposes it was assumed that pre -construction conditions would be largely similar to existing conditions..

Conclusion Narrowing the bridge to 2.lanes northbound at Atlantic and District would degrade AM peak hour LOS E to LOS F while the PM peak hour LOS will remain at LOS C. cc: Frank Wein, URS.
