Page 2 of - Revised November 2008 ---PAGE BREAK--- ENVIRONMENTAL REEVALUATION Gene Autry Way (West) Ilighway Improvement Project 2009 State ofCahfornia Deparhent of Transportation District 12 3347 Michelson Drive, Suite 100 Irvine, CA 91612 ---PAGE BREAK--- The purpose of this Reevaluation is to determine whether there has been substantial change in the social, economic, and environmental effects of the proposed prqiect. This could occur by changes in the project itself or with respect to the circumstances under which the project is to be undertaken. I. EXISTING FACILITY The Gene Autry Way (West) extension between Haster Street and Interstate 5 (I-5) does not currently exist. Existing land uses along the proposed Gene Autry Way (West) extension include multifamily residences, three mobile home parks, a hotel, and light industrial land uses. Currently, there are existing property walls that range from 6 feet (ft) to 8 ft for the multifamily residences, mobile home parks, and hotel. All land uses within the project area are similar in elevation to I-5, Manchester Avenue, and Haster Street. I-5 is currently an eight-lane interstat€ highway (four mixed-flow lanes in each direction), with one high-occupancy vehicle (HOV) lane and one auxiliary lane in each direction. The posted speed limit on I-5 is 65 miles per hour (mph). Manchester Avenue is a two-lane arterial roadway with a posted speed limit of 35 mph. Haster Street is also a four-lane arterial roadway with a posted speed limit of 40 mph (Figue II. PROJECT DESCRIPTION The City of Anaheim, in cooperation with the Califomia Department of Transportation District l2 (Caltrans), proposes to construct Gene Autry Way (West) between Haster Street and I-5. The project includes constructing a new east/west roadway (Gene Autry Way [West]) and widening an existing north./south roadway (Haster Street) within the City of Anaheim in Orange County, Califomia. Gene Autry Way (West) (proposed project) would be constructed as a sixJane (three lanes in each direction) arterial highway extending from Haster Street to a point approximately 2,400 ft to the east. In order to accommodate the additional traffic from the new roadway, the proposed project also includes widening Haster Street from four to six through lanes, with a center tum lane from approximately 520 ft south of Katella Avenue to approximately 600 ft north of Orangewood Avenue. The purpose of the proposed improvements is to provide efficient and effective transportation operations along I-5 and improve acc€ss across I-5 between the westerl and eastem portions of the City of Anaheim and provide westerly access to the I-5 HOV lanes. In particular, this project would reduce traffic volumes along Katella Avenue to the north and facilitate overall mobility within the City of Anaheim. III. PREVIOUS ENVIRONMENTAL APPROVALS A Final Environmental Impact Report (FEIR) for the Gene Autry Way (West) Highway Improvement Project was certified by the City of Anaheim in August 2003. An Environmental Assessment/Finding of No Significant Impact (EA,/FONSI) for the proposed project was approved by the Federal Highway Administration @HWA) onMay 22,2003. Altemative 7 (Haster Street [East]/Gene Autry Way [North]) was identified as the Preferred Alternative by the City of Anaheim because it would displace the fewest number of multifamily residential units and result in less extensive noise impacts and the lowest right-of-way (ROW) costs of any of the nine build alternatives. For the purposes of this Reevaluation, Altemative 7 (the Preferred Altemative) is referred to as the proposed project. This Reevaluation specifically addresses the Gene Autry Way (West) extension project, which includes the widening of Haster Street. ---PAGE BREAK--- iH:- d FF UE *32 l€e ;9 E i^ -.Js= 6S P ---PAGE BREAK--- IV. PROJECT CHANGES The reevaluation is required for the project since there have been changes in existing setting and implementation of new laws and regulations. IV.A Changes in Project Design The design and scope of the proposed project remains the same as evaluated in the FEIR/FONSI. IV.B Changes in Environmental Setting or Circumstances Since approval of the FEIR/FONSI, additional changes in development have occurred near the study area. The City of Anaheim has approved the Platinum Triangle Master Land Use Plan (MLUP) and Platinum Triangle Mixed Use (PTMtI) Overlay Zone, east of I-5, which provides for redevelopment of 820 acres with residential, commercial, retail, and recreational uses. The Platinum Triangle is generally located east ofl-5, west ofthe Santa Ana River channel and State Route 57 (SR-57), south of the Southem California Edison easement and north of the City limit. The project study area is located to the west of the designated Platinum Triangle limits. The adopted Platinum Triangle MLUP/PTMU Overlay Zone provides for 10,266 residential units, approximately 2.26 million square feet (sf) of commercial uses, and approximately 5.1 million sf of office. As of November 19, 2008, a total of 390 dwelling units and24,844 sf of new commercial space have been constructed within the Platinum Triangle, and 1,530 new dwelling units and 13,739 sf of commercial space are under construction. Another 6,445 dwelling units, 413,871sf of commercial uses, and 899,419 sf of office are approved but not under construction. The City of Anaheim is currently preparing Draft Subsequent Environmental Impact Report No. 339 (DSEIR No. 339) to analyze the impacts of increased development intensities in the Platinum Triangle. Approval of the proposed amendments would result in maximum development intensities of I 8,909 dwelling units, 14,340,522 sf of offrce use s, 4,909,682 sf of commercial uses, and 1,500,000 sf of institutional uses within the Platinum Triangle. IV.C Change in Environmental Circumstances The following new regulations have been implemented subsequent to approval of the FEIR"/ FONSI and are addressed in this Reevaluation: Fine Particulate Matter/Coarse Particulate Matter (PM2 5/PM16), per the Final Transportation Conformity Rule (71 FR 12468) (EPA, March 10, 2006) and Transportation Conformity Guidance for Qualitative Hot-Spot Analyses in PM2.5 and PM16 Nonattainment and Maintenance Areas (EPA 420-8-06-902, March 2006). Mobile Source Air Toxics, using EMFAC2007. Water Quality Permitting, per the most recent County municipal permit and statewide construction permit. Native American Consultation ---PAGE BREAK--- V.I NVIRONMENTAL IMPACTS AI\D MEASUREI TO MINIMIZE HARM The ' nformation provided below utilizes the direction outlined wi irin the Caltrans Standard Envi, onmental Reference (SER) Annotated Outline (August 200f t and the Preliminary Envilonmental Study (PES) form (May 30, 2008) to evaluate qtr6r,gos to the project scope, regu iations and requirements, and environmental setting that ntay affect the conclusions ofthe FEIR,/FONSI. V.A Geology/Soils/Seismic/Topography FEIR/FONSI Analysis. According to the FEIR/FONSI, due to the relatively flat topography of the proposed project, project construction would require minimal amounts of grading for the roadway; however, construction of sound walls would require some excavation. The proposed project could be subject to strong ground shaking, as the project would be located within the seismically active Southem Califomia region. Also, given the urban nature of the project area, the proposed project would be located within a built-out area and would not result in a substantial increase in impervious surfaces. Additionally, construction activities would expose soils that could be eroded due to wind or water conditions. The FEIR/FONSI acknowledged that construction activities would be subject to the conditions of the National Pollutant Discharge Elimination System (MDES) Permit, which is administered by the Regional Water Quality Control Bomd Best Management Practices (BMPs) would be implemented to control soil erosion during project construction as part of the permit conditions and the proposed project would be constructed in compliance with all applicable seismic safety standards and guidelines. The FEIR/FONSI determined that there would be no significant geology/soils/seismic/topography impacts associated with the proposed project. Conclusion. There have been no changes to land uses or the project scope within the study area that would have affected geolory, soils, seismicity, or topography. The proposed project would be required to comply with the most recent NPDES requirements as further discussed in Section V.C, Hydrology and Water Quality, below. V.B Air Quality FEIR/FONSI Analysis. The FEIR/FONSI concluded that the proposed project is in conformance with the State Implementation Plan (SIP) and is consistent with the requirements of the federal Transportation Conformity Rule. To make this finding, it was determined that the proposed project was consistent with the Regional Transportation Plan (RTP) and Regional Transportation knprovement Program (RTIP) and would not exacerbate an exceedance of federal or State carbon monoxide (CO) standards. Although temporary air quality impacts associated with the construction of the proposed project would occuq compliance with South Coast Air Quality Management District (SCAQMD) regulations, including Rule 402, the Nuisance Rule, and Rule 403, Fugitive Dust, would minimize potential temporary air quality impacts and were not considered substantial. Conclusion. ln general, regional air quality has improved since approval of the FEIRiFONSI. There have been changes to the existing and projected future traffic volumes. In particular, adoption of the Platinum Triangle MLUMP/PTMU Overlay Zone, to the east of I-5, increases the allowable development between the I-5lSR-57/State Route 91 (SR-91) area, with the majority of ---PAGE BREAK--- the Platinum Triangle located south of East Cerritos Avenue. An assessment of the effect of changes in existing and forecast traffic volumes has been included in the Air Quality Technical Report (LSA 2009). The results of the air quality analysis confirmed the prior fmdings of the FEIR/FONSI. The project is listed in the 2008 RTP, which was found to be conforming by the FHWA.rFederal Transit Administration (FTA) on June 5, 2008. The project is also listed in the 2008 RTIP, which was found to be conforming by the FHWAffTA on November 17, 2008. The proposed project is consistent with the scope of design concept of the RTIP. Since the project is not expected to result in any concentrations exceeding the 1-hour or 8-hour CO standards, a detailed CALINE4 CO hot-spot analysis was not required. Therefore, the proposed project is in conformance with th€ SIP and the conclusions of the FEIR /FONSI remain valid. Similar to the conclusions within the FEIR/FONSI, temporary impacts result from construction activities that produce combustion emissions from various sources such as site grading, utility engines, on-site heavy-duty construction vehicles, equipment hauling materials to and from the site, and motor vehicles transporting the construction crew. In order to reduce the amount of emissions during the construction ofthe proposed project, the Department Standard Specifications for construction (Sections l0 and l8 for dust control and Section 39-3.06 for asphalt concrete plants) will be adhered to. Additionally, SCAQMD Rule 403 for reducing fugitive dust emissions (PM1s) will also be adhered to. The best available control measures (BACM), as specified in SCAQMD Rules 402 and 403, shall be incorporated into the project commitments. With the implementation of standard construction measures, fugitive dust emissions from construction activities would not result in adverse air quality impacts. The project will also comply with all SCAQMD requirements. Therefore, with the incorporation of the measures identified in the FEIR/FONSI, the proposed project would not result in adverse construction air quality impacts and the conclusions of the FEIR/FONSI remain valid. PMro and PM2.5, The proposed project is within a nonattainment area for federal PIvl2 5 and PMls standards. Therefore, per 40 Code ofFederal Regulations (CFR) Part 93, analyses are required for conformity purposes. However, the Environmental Protection Agency (EPA) does not require hot-spot analyses, qualitative or quantitative, for projects not listed in Section 93.123(bXl) as an air quality concem. The proposed project does not qualify as a project of air quality concem (POAQC) because the proposed project is not a new or expanded highway project that would have a substantial number ofor increase in diesel vehicles, the future traffic volumes along this segment of Gene Autry Way are not projected to exceed 125,000 average daily vehicles or 10,000 daily truck trips, the proposed project would reduce the traffic volumes along Haster Street and Katella Avenue, and the average daily truck volumes were calculated using the 3.5 percent diesel truck traffic on I-5 within the project area. Based on the Traffic Report, the proposed project would not worsen the level of service (LOS) at any of the intersections within the project area that are currently operating at a LOS of D, E, or F. The proposed project would improve the traffic flow and LOS at several intersections within the project area. tn addition, the proposed project does not include the construction ofa new bus or rail terminal, does not expand an existing bus or rail terminal, and is not in or affecting locations or areas, or categories of sites that are identified in the PM2.5 and PMq6 applicable implementation plan or implementation plan submissiorq as appropriate, as sites of violation or possible violation. Therefore, the proposed project meets the Clean Air Act (CAA) requirements and 40 CFR 93.1l6 without any explicit hot-spot analysis and would not create a new, or worsen an existing, PMz.s or PM16 violation, and the findings of the FEIR/FONSI remain valid. The project-level particulate matter hot spot analysis was presented to SCAG's Transportation Conformity Working Group (TCWG) for discussion and review on June 23,2009. Per Caltrans ---PAGE BREAK--- Headquarters policy, all nonex ;mpt projects need to go through review by the TCWG. This project was approved and conc,rrred upon by Interagency Consultation at the TCWG meeting as a project not having adverse impacts on air quality and meets the requirements of Clean Air Act and 40 CFR 93.116. Mobile Source Air Toxics. Subsequent to the FEIRffONSI, the Department has adopted guidance regarding assessment of Mobile Source Air Toxics (MSAT). Under the proposed project, it is expected that there would be similar or lower MSAT emissions in the study area relative to the No Build scenario due to the level of service (LOS) improvements, identified in the Traffic Report. On a regional basis, the EPA's vehicle and fuel regulations, coupled with fleet turnover, would cause substantial reductiors over time that in almost all cases wili cause regionwide MSAT levels to become substantially lower than current conditions, and the conclusions of the FEIR/FONSI regarding regional air quality remain valid. Climate Change. The proposed project would reduce the number of vehicle hours traveled (VHT) within the project area by improving access across I-5 between the Anaheim Resort Area on the west and the Platinum Triangle Area on the east. The Gene Autry Way (West) extension is identifred in the Transportation Element of the City of Anaheim General Plan and is included in the RTP and RTIP. The extension of Gene Autry Way would provide an additional opportunity for existing and forecast traJfic to cross the I-5 within this portion of the City of Anaheim (including vehicles, trucks, buses run by the Orange County Transportation Authority and the City's local shuttle within the Resort and Platinum Triangle areas), thus reducing congestion on the adjacent arterial crossings at Katella Avenue and Batl Road and improving the overall operation of the arterial network in this area. As discussed in the traffic analysis, the proposed project would not worsen the LOS at any of the intersections within the project area that are currently operating at a LOS of D, E, or F and would improve the traffic flow and LOS at several intersections within the project area. The COz emissions associated with vehicles on the local roadway system would be reduced due to the reduction in VHT and the improved traffic flow. V.C Water Resources/Waterways and Hydrolory FEIRVFONSI Analysis. As discussed in the FEIR/FONSI, there are no surface water resources or open drainage channels in the immediate vicinity ofthe project site, and the closest water body to the project site is the Santa Ana River, which is located approximately 1.5 kilometers (1 mile) to the east of the project site. Stormwater runoff in the project area is collected in local underground storm drains. Impacts included the potential for temporary effect on water quality or local surface water resources due to the wind or water erosion of exposed soils dwing the construction process. Impacts to water quality or local surface water resources during construction were not considered substantial, because the proposed project would comply with the NPDES Permit requirements and would include a Stormwater Pollution Prevention Plan. Pollutant levels and impacts to the water bodies from the construction of the proposed project result in runoff associated with vehicular traffic. As described in the FEIR/FONSI, permanent impacts resulting from the proposed project would result from an increased amount of impervious surface in the area through the construction of the new roadway. A substantial portion of the project alignment is already developed with impervious surfaces due to the presence of mobile homes and multifamily apartment buildings, ---PAGE BREAK--- and the increase in impervious area would be limited to any landscaped areas associated with mobile homes and residential structures that are converted to roadway uses. The proposed project would also increase runoff constituents in the immediate area, specihcally particulates, total nitrogen, lead, zinc, and chemical oxygen demand, due to traffic traveling on the new roadway. Runoff from the project site flows into underground storm drains, which connect to drainage channels that ultimately discharge into the Pacific Ocean. The FEIR/FONSI concluded that the increase in impervious area and runoff constituents would not result in substantial impacts to water resources or water quality, pa(icularly given that the project would comply with NPDES requirements. Conclusion. Although there has been no substantial change in land uses that would affect the quality of existing runoff, since approval of the FEIRTFONSI, there have been updated requirements for control of runoff, including the compliance with the most recent County municipal permit and statewide construction permit. The project area ultimately drains to the Santa Ana River, Reach 2 (17s Street in Santa Ana to Prado Dam). Lr general, the quality of surface water and groundwater in the Santa Ana River Basin becomes progressively poorer as water flows Reach 2 of the Santa Ana River is not on the 2006 Clean Water Act Section 303(d) List of Water Quality Limited Segments, approved by the State Water Resources Control Board in October 2006. On March 8,2007,the EPA partially disapproved Califomia's 2004-2006 303(d) list it disapproved the State's omission of impaired waters that met federal listing regulations or guidance). On June 28,2007, the EPA approved the addition of64 waters and 37 associated pollutants to the State's 303(d) list. The Santa Ana River, Reach 2, is not on the list ofwaters being added to the 2006 303(d) list. The Poder-Cologne Act establishes a regulatory program to protect water quality and protect beneficial uses of State waters. It empowers the to formulate and adopt, for all areas within the regions, a Basin Plan that designates beneficial uses and establishes water quality objectives that, in its judgment, will ensure reasonable protection ofbeneficial uses. The following beneficial uses are identified in the Basin Plan for the Santa Ana River, Reach 2: . AGR: Agricultural Water Supply . GWR: Groundwater Recharge . REC-I: Contact Water Recreation (swimming/wading) . REC-2: Noncontact Water Recreation (boating/fishing) . WARM: Warm Freshwater Habitat (for fish amenable to reproduction in warm water) . WILD: Wildlife Habitat (for wild plants and animals) . RARE: Rare, Tbreatened or Endangered Species (habitat for plants or animals) BMPs will be incorporated idto project design to meet the requirements identified in the City's Water Quality Management Plan (WQMP) Procedures and the County's 2003 Drainage Area Management Plan (DAMP). The proposed proj ect would also comply with the requirements listed within the City's Project Review Checklist for WQMP Requirements, which includes a signed statement certifuing that the provisions of the WQMP have been accepted by the applicant and that the applicant will strive to have the plan carried out by all future successors ur accordance with the Crty of Anaheim's "Notice of Transfer of Responsibility'' procedures. With ---PAGE BREAK--- the implementation of this standard measure, the conclusions of the FEIIT trONSI regarding operational water quality impacts remain valid. In addition, water discharge occurring during construction activities will comply with the NPDES General Permit For Storm Water Discharges Associated with Construction Activity (General Permit) Water Quality Order 99-08-DWQ. The Disturbed Soil Area (DSA) for the construction of the proposed project is approximately 10.5 acres. With the implementation of this standard measure, the conclusions of the FEIR/FONSI regarding water quality impacts during construction remain valid. V.D Biological Resources FEIR/FONSI Analysis. According to the FEIR/FONSI, construction of the proposed project would require the removal of ornamental landscaping and some street trees. However, the project would include new landscaping and street trees in accordance with City standards. Additionally, the project site is located in a developed urban area and no sensitive or listed plant or animal species or habitat exists in the project area. Therefore, impacts to biological resources w€re considered not substantial. Conclusion. Based on a recent field review of the project area, the biological setting remains the same. Given there are no changes to the environmental setting and the project scope, the potential effects to biological resources described in the FEIR/FONSI would remain unchanged. There is the potential to remove mature trees during construction activities. Tree removal could affect migratory birds if they are nesting in these trees. With implementation of the standard m€asure outlined in Section VI, potential impacts to migratory birds are not substantial. V.E Noise FEIRUFONSI Analysis. As discussed in the FEIR/FONSI, local traffic is the dominant noise source at those locations along or within the immediate vicinity of Haster Street. Noise levels at receptor locations along Haster Street were reported between 69 and 72 decibels acoustic (dBA). The dominant noise sources along Wakefield Avenue were associated with residential activities as traffic volumes were relatively low. As a result, noise levels were quieter in this area compared to thos€ sites along Haster Street. Long-term impacts associated with the operation of the proposed project could result in exterior noise levels at sensitive receptors that are within I dBA or exceed the FIIWA exterior noise criteria for noise abatement. Project operation could also result in increases in ambient noise levels. As a result, the FEIRTFONSI recommended that sound walls be located alofig either side of the proposed Gene Autry Way (West) and along the east side of Haster Street, as necessary. At those locations where sound walls are not feasible, altemative off-site mitigation would be incorporated such as the installation of double-pane windows and air-conditioning. With the implementation of these measures, operational noise impacts were not considered substantial. Conclusion. Given the changes in existing and forecast traffic volumes, an updated Noise Analysis (LSA, 2008) was completed that follows the August 2006 Noise Protocol and uses the October 1998 Technical Noise Supplement (TENS) noise model. The traffic noise level results for the existing pealg future no build, and future build 2035 scenarios were evaluated as part of the Noise Analysis. Results indicated that out of the 103 modeled receptor locations, 4 receptors ---PAGE BREAK--- currently approach or exceed the 67 dBA L* Noise Abatement Criteria (NAC) under the existing peak traffic noise condition. Under the future build conditions, of the 103 modeled receptor locations, 3l receptors would "approach or exceed" the NAC under Activity Category B, which has an exterior NAC of 67 dBA L"q. Also, of the 103 modeled receptor locations, 23 receptors would experience a substantia.l noise increase of 12 dBA or more over their corresponding modeled existing peak noise level. Noise abatement measures were evaluated for receptors located within the project limits that would be or would continue to be exposed to traffic noise levels approaching or exceeding the NAC or would experience a substantial noise increase of 12 dBA or more over their corresponding modeled existing peak noise level. All properties requiring abatement consideration are within Category B (67 dBA L"qNAC). Three sound barriers (SB Nos. l, la, and 2) were evaluated along the ROW for the futwe 2035 build condition to reduce noise levels at receptor locations within the project limits. SB No. 1a is similar to SB No. I , but with the east end wrapped around the residential property line to compare the effectiveness of the sound barrier. SB No. 1 was evaluated at two locations to compaf,e its ability to reduce traffic noise levels. Under the first scenario, SB No. I was evaluated along the north side of the proposed Gene Autry Way (West) ROW. Under the second scenario, SB No. la was evaluated along the portions of Gene Autry Way (West) ROW and the property line of the Plantation Mobile Estates. The sound barrier modeling results indicate that SB No. 1a located along the Plantation Mobile Estates property line performs better by benefiting more residences than SB No. I located only along the proposed Gene Autry Way ROW line. SB No. la was determined feasible and reasonable at a height of 8 feet is recommended. SB No. 2 was evaluated on the south side of the proposed Gene Autry Way (West) extension, from Haster Street to just east of the mobile home park, and an 8 foot sound barrier was determined feasible and reasonable and is recomrnended. The western end of SB No. 2 wraps around the property at the Gene Autry Way (West)/Haster intersection to shield traffic noise from South Haster Street and the proposed Gene Autry Way (West). The eastem end of SB No. 2 wraps around the end of the last multifamily structure on Gene Autry Way (West). The conclusions made within the FEIR TFONSI remain the same and potential effects associated with noise impacts are not considered substantial with the implementation of SB Nos. la and 2. V.F Land Use/?lanning FEIR/T'ONSI Analysis. Although project construction would introduce a new roadway in place ofan existing residential land use, the proposed improvements are consistent with the Circulation Element of the City of Anaheim General Plan (General Plan) and the Master PIan of Arterial Streets (I\4aster Plan). As identifred in the FEIR/FONSI, both Haster Street and the proposed Gene Autry Way (West) are identified as primary arterials by the General Plan and have been listed as such since at least 1984. The proposed project would not conflict with any other local plans or policies. The proposed project would be constructed through a residential neighborhood. As the adjacent neighborhoods would remain relatively intact, and as the multifamily residential units to the south and mobile homes to the north are separated by a private wall with no through access provided, the proposed project would not divide an established community. Therefore, the implementation ---PAGE BREAK--- of the plannecl uses within the study area would not be adversely affected by the construction of the proposed projecl The proposed project would not result in the conversion of prime farmland to nonagricultwal use, nor would it conflict with agricultural zoning designations or a Williamson Act contract. Conclusion. Within the project study area, no new development has occurred. Removal of some of the mobile homes in the Plantation Mobile Estates has occurred, and several multifamily units on Haster Street have been removed or modified by the City as part of the right-of-way acquisition process for this project. Since approval of the FEIR/FONSI, the City of Anaheim has adopted the Platinum Triangle MLUPiPTMU Overlay Zone located to the east of I-5 from the project area. As discussed in Section IV.B above, the City of Anaheim approved the Platinum Triangle MLIIP/PTMU Overlay Zone, located east of I-5, which provides for redevelopment with residential, commercial, retail, and recreational uses. As discussed previously, the Platinum Triangle is composed of an area within Anaheim east of the project area that generally surrounds and includes Angel Stadium, Honda Center, and The Grove of Anaheim. The Platinum Triangle is anticipated to bring high density, mixed-use, office, restaurant, and residential projects to replace older industrial developments within the area. The proposed project is designed to accommodate existing and future traffic in order to improve mobility within the City of Anaheim, and will be constructed within an urbanized area that has a well-developed infrastructure system already in place. The proposed project would help accommodate planned growth consistent with the City's General Plan and regional land use - plans. Since there are no changes to the land use setting in the direct vicinity of the project study area since approval of the FEIR/FONSI, the conclusions of the FEIR/FONSI remain valid. V.G Hazardous Waste FEIRUFONSI Analysis. An Initial Site Assessment (ISA) was conducted for the FEIR/FONSI and concluded that general grading and excavation activities associated with the proj ect construction would not €ncounter substantial amounts of hazardous materials or contaminated groundwater. According to the Phase I Environmental Site Assessment (ESA) @hase I) (Ninyo and Moore, 2000), there were two former gasoline stations identified, operated by Mobil and Texaco, that were located just outside the project limits on the southwest and southeast comers of Katella Avenue and Haster Street. Both facilities were noted to have affected groundwater. At the time of the Phase I ESA, both facilities were undergoing soil and groundwater remediation. However, the Mobil station was issued a closure letter by the lead regulatory agency and groundwater monitoring occurring at the Texaco gasoline station did not yield detectable concentrations of petroleum hydrocarbons. Therefore, the Phase I ESA did not consider these sites a potential concern during the construction of the proposed project. ln addition, the Phase I ESA also indicated that potentially displaced multi-family residential units may include asbestos-containing materials (ACMs), which would require removal prior to demolition. However, these materials would be removed prior to demolition in accordance with the applicable environmental health and safety hazards and regulations. 10 ---PAGE BREAK--- Project operation could increase the potential for release of hazardous materials due to truck traffic along the proposed Gene Autry Way (West) roadway. However, given the relatively low truck volumes and the fact that the transport and cleanup of hazardous materials is strictly regulated, no adverse impacts are anticipated. Conclusion. Based on the age ofthe records review and field survey in the ISA, a supplemental ISA (LSA 2008) was conducted to assess whether there were any changes to hazardous waste/materials setting since the approval of the FEIR/FONSI. The updated database search within the ISA indicated l6 leaking underground storage tank (LUST) incidents, three California Hazardous Material Incident Reporting System (CHMIRS) incidents, one clandestine drug lab (CDL), and one Comprehensive Environmental Response, Compensation, and Liability Information System (CERCLIS) No Further Remedial Action Planned (CERC-NFRAP) incident within 0.50 mile of the project limits. However, based on the regulatory status and/or known extent of impact, it does not appear that any of the off-site incidents have the potential to impact the site. In addition, groundwater is relatively deep [110 ft below ground surface (bgs)] and dewatering is not anticipated for the project. Therefore, it is unlikely that any off-site subsurface contaminants have or will migrate to the project area. As part of the acquisition of two properties within the study area, subsurface impacts associated with the importation of off-site fill, a former septic system, a former underground storage tank (UST), and soils impacted with petroleum hydrocarbons and arsenic were identified. A previous subsurface investigation recommended that a qualified environmental consultant be used to monitor for and remove impacted soils. Based on conversations with AMEC, the consultant that prepared the previous reports, it appears that adequate monitoring and removal of impacted soils was conducted during the demolition of the properties. In addition, surveys for ACMs, lead-based paints (LBPs) and chromium paints may be present on existing multi-family residential structures that may be acquired as part of the proposed project. However, similar to the recommendations made within the original ISA, these materials would be removed, if present, prior to the demolition any structure that may be required as part of the proposed project. Based on the governrnent records search, site survey, and aerial photograph review, the areas of concern continue to be ACMs in properties to be acquired and demolished. However, since the approval of the FEIR/FONSI, new requirements and regulations have been instituted by the federaUState regulatory agencies for the testing and handling of hazardous materials. These new or updated requirements include the testing and removal of LBPs and/or chromium-based paint on existing structures, testing for aerially deposited lead and the removal of themroplastic paint and traffic in roadways, and testing in the event that potentially leaking aboveground electrical transformers containing biphenyls (PCBs) are to be disturbed. These standard measures outlined in Section VI to address these potential environmental concerns during construction. The conclusions in the FEIRTFONSI related to hazardous materials remain valid. V.H Cultural Resources FEIR/T'ONSI Analysis. According to the FEIRffONSI, project construction could reveal previously unidentified archaeological resources. Only one historical resource, located at 2040 Haster Street, was identified as a locally significant historical resource in the Historic Property Survey Report for the Gene Autry Way (West) Extension Project (December 2000). However, based on National Register of Historic Places (National Register) criteria, this property is not l1 ---PAGE BREAK--- eligible for the National Register. Although this historical resource would be subject to noise and visual impacts during construction, such impacts are considered temporary and would not substantially affect the resource. The FEIR {FONSI recommended monitoring by a qualified archaeologist during construction activities of the proposed project. Standard measures to protect unknown finds of buried cultural resources or human remains during construction were also included as avoidance measures within the FEIR/FONSI. Conclusion. A supplemental Cultural Resources Study (CRS) was conducted for the proposed project (LSA 2009). The CRS included a new records search and also included a review of all recorded historic and prehistoric archaeological sites within a 0.25-mile radius of the project area, as well as a review of known cultural resource suwey and excavation reports. ln addition, LSA examined the Califomia State Historic Resources Inventory, which includes the National Register, California Historical Landmarks, Califomia Points of Historical Interest, and various local historic registers. The entire project area has been surveyed. The CRS concluded that there are no previously recorded archaeological sites within the project area. Architectural properties were also examined as part of the CRS to determine whether they were eligible for listing in the National Register. It was concluded that all properties within the project area can be addressed per the Programmatic Agreement Among the Federal Highway Administration, the Advisory Council on Historic Preservation, the Califomia State Historic Preservation Officer, and the Califomia Department of Transportation Regarding Compliance with Section 106 of the National Historic Preservation Act, as it Pertains to the Administration of the Federal-Aid Highway Program in Califonia (2004), Attacbment 4, Property Type 4. No buildings within the project area are eligible for listing in the National Register. A Native American Consultation was also conducted as part of the CRS. On July 10, 2008, a letter was sent to the Native American Heritage Commission (NAHC) requesting a search of the Sacred Lands File to identif areas of religious or cultural significance to Native Americans. The Sacred Lands File search did not identify any Native American cultural resources in or near the project area; however, the NAHC recommended that l6 Native American individuals/groups be contacted. Several Native Americans identified the project area as sensitive for cultural resources and requested both Native American and archaeological monitors while construction occurs within undisturbed native soil. The CRS determined that although several Native Americans have identified the project area as being sensitive for cultural resotuces (in general) and have reqwested Native American monitors while construction occurs within the undisturbed native soil, no known cultural resources were identified; thus, no specific reasons were identified for recommending montoring. Therefore, the conclusions of the FEIR/FONSI relative to cultural resources remain valid. V.I Paleontological Resources FEIRiFONSI Analysis. Paleontological resources were not evaluated in the FEIR/FONSI. Conclusion. A Paleontological Identification and Evaluation Report was completed for the proposed project (LSA 2008). To ensure that research was comprehensive, the paleontological resources "study area" was expanded to a 328 ft radius beyond the project area of direct impact. Prior to the field survey, t2 ---PAGE BREAK--- research was conducted to locate fossil localities both within the project area and in an area much larger than the study area. The proposed project is located within an area that contains sediments with potential to contain significant noruenewable paleontological resources. However, the potentially fossiliferous sediments will only be encountered if excavation extends deeper than 8-10 ft below the natural surface. According to current design, this is not likely to occur except in areas where driven piles or cast-in-drilled-hole (CIDH) piles will be installed. Both driven piles and CIDH piles are almost impossible to monitor and safely recover resources from. In addition, because of their small footprint, they are unlikely to impact any fossils. No special paleontological situatiors that would require project redesign to avoid critical localities or strata were identified. ln addition, as it is unlikely that excavation would extend to depths where fossils will be encountered, a Paleontological Mitigation Plan @MP) would not need to be prepared and impacts to paleontological resources are not considered substantial. However if project plans change and excavation will extend deeper than 8-10 ft below the natural surface, a PMP would be developed as outlined in Section VI. V.J VisuaUAesthetics FEIR/FONSI Analysis. The visual analysis conducted for the FEIR/FONSI evaluated the project's potential visual effects both from and looking toward the roadway. According to the FEIR/FONSI, the proposed project was evaluated for its potential effects on the existing visual environment associated with both project construction and operation. The potential visual impacts that would occur as a result of construction of the proposed project would include the removal of structures and vegetation within the ROW, construction of the roadway, and vacation of th€ sit€s after construction is completed. Visible construction activities would include demolition" grading, truck trips (debris hauling), paving, and other roadway-related construction activities. Project construction could represent a visual nuisance to local residents; however, this impact is considered temporary and limited in scope. Under the proposed project, partial acquisitions with displacements would be required at the southern end of the Satellite Mobile Home Park and Plantation Mobile Estates. These property acquisitions would include the removal of mature trees, a concrete block private security/sound wall, and landscaping. The proposed project would partially or fully obstruct views to the south from the mobile home parks due to the existing private concrete block wall. However, the visual quality and character of the views under the existing location is low because the vegetation removed as part of the proposed project is not considered unique, is discontinuous, and does not provide visual harmony. Existing walls that would be part of the proposed project would be replaced with new sound walls where feasible and reasonable, which would buffer adjacent residences from the noise and visual effects of traffic on Haster Street. The remainder of the apartments located within the proj ect limits on both sides of Haster Street have unobstructed views of Haster Street. However, the quality of the view is also considered low due to common varieties of vegetation, presence of the existing four-lane street, and the lack of vividness. The proposed project would alter the view from the residences to the project by removing vegetation and moving traffic lanes closer to the residences. However, vegetation or streetscape that is removed by the proposed project would be replaced in accordance with established City of Anaheim policies. As a result, the FEIR/FONSI concluded that with the l3 ---PAGE BREAK--- implementation of City landscape policies, impacts to the existing visual quality of the surrounding area of the project limits would not be substantial. Concfusion. The project area is located within an existing urbanized area. Since there are no changes to the visual quality ofthe project study area and no substantial changes in project design since approval of the FEIR/FONSI, the conclusions of the FEIR/FONSI remain valid. V.K Public Services and Utilities FEIR/FONSI Analysis. a. Public Utilities. Numerous public utilities within the study area were identified in the FEIR/ FONSI, and preservation in place and./or relocation of utilities within the project area were required. As discussed in the FEIR /FONSI, the proposed project does not include new residential, commercial, or industrial development that could increase the need for public services, such as fire protection, police protection, schools, or other public facilities. Utilities impacted by the proposed project would either be protected in place or moved. No new or upgraded storm water drainage facilities would be required to accommodate runoff from the proposed project. Potential impacts to public utilities were not considered substantial. Conclusion. Since the proposed project does not include new residential, commercial, or industrial development, the conclusions made in the FEIR/FONSI remain unchanged. b. Transit. As discussed within the FEIR/FONSI, bus service in the project area is currently provided by the Orange County Transportation Authority (OCTA). OCTA operates bus routes in the immediate project area, along Haster Street, and along Katella and Orangewood Avenues. Bus stops are located along Haster Street, directly opposite of Wakefreld Avenue, in the southbound direction and just north of Leatrice Lane in the northbound direction. The bus route may be impacted during construction activities. However, these impacts are considered temporary, and with the implementation of a Traffic Management Plan described in the FEIR/FONSI, these impacts were not considered substantial. Conclusion. Since no new bus routes have been established in the project area since the approval of the FEIR/FONSI, the conclusions of the FEIR/FONSI remain unchanged. c. Bicycle Facilities. No bicycle facilities are located within the project area. Therefore, no impacts to bicycle facilities were anticipated in the FEIR/FONSI. Conclusion, Because no new bicycle facilities have been or planned in the project area since the approval of the FEIRtrONSI, the conclusions made in the FEIR/FONSI remain unchansed. l4 ---PAGE BREAK--- V.L Park and Recreational Facilities FEIR/T'ONSI Analysis, There were no parks or recreational facilities located within the project limits at the time of the FEIR/FONSI was approved. Conclusion, No additional parks or recreational facilities have been acquired and/or constructed since the approval of the FEIR/FONSI. Therefore, the conclusions made within the FEIR/FONSI are still valid. V.M Growth FEIRyFONSI Analysis. As discussed within the FEIR/FONSI, the proposed project would be located within an urbanized area that has a well-developed infrastructure system already in place. The proposed project is designed to accommodate existing and future traffic in order to improve mobility within the City of Anaheim. Therefore, the project operation would not result in significant local or regional population growth. Rather the proposed project would accommodate planned growth consistent with local and regional Land Use Plans. Conclusion. As discussed previously, since the approval of the FEIR/FONSI, the approval of the Platinum Triangle MLUP/PTMU Overlay Zone has occurred. The introduction of mixed-use development, which includes high-density urban residential housing, office, and commercial uses, has initiated growth within the immediate area of the project site. However, the proposed project is located within an urbanized area that has a well-developed infrastructure system already in place and is designed to accommodate existing and future traffic in order to improve mobility within the City of Anaheim, consistent with the Circulation Element of the General Plan. The extension of Gene Autry Way (West) has been identified within Figure C-1, Planned Roadway Map, located within the Circulation Element of the May 2004 General Plan. The extension of Gene Autry Way (West) was planned in order to provide additional east/west vehicular/pedestrian movement across I-5 and provide for growth consistent with the General Plan. Development within the Platinum Triangle anticipated implementation of the City's arterial network, as outlined in the Circulation Element. Construction of Gene Autry Way (West) was not required to implement the Platinum Triangle MLUPfTMU Overlay Zone.r Therefore, the project operation would not result in unplanned local or regional population growth. The proposed project would help accommodate planned growth, consistent with local and regional Land Use Plans, and the conclusions of the FEIR/TONSI remain valid. V.N Community Character and Cohesion FEIRUFONSI Analysis. As discussed within the FEIR/FONSI, the residential property acquisitions and displacements associated with the proposed project could adversely affect the established community. Although eligible residents would be entitled to relocation assistance, it is likely that they would be physically separated from their neighbors in the immediate area and relocate to homes elsewhere. Although adequate replacement is expected to be available in the greater Orange Corurty area, residents who have come to rely on neighbors or have otherwise t The Platinum Triangle Master Land Use Plan, City of Anaheim Planning Services Division, April S, 2008. IJ ---PAGE BREAK--- formed relationships in the project area would be adversely impacted through the disruption of their present residential community. Although residential displacements and construction activities would be disruptive and have an adverse effect on the community, the proposed project would not divide an established neighborhood. The proposed highway alignment is the approximate location ofan existing alley and privacy wall that separates the multi-family residential neighborhood to the south from the mobile homes to the north. There is no tbrough access connecting the mobile home parks with the multi-family residential neighborhood to the south. Furthermore, under the proposed altematives, the overwhelming majority of multi-family residences in the neighborhood bounded by Haster Street on the west, Orangewood Avenue on the south, and Mountain Avenue on the east, as well as the mobile home parks on the north, would remain intact and their sense of community would be maintained. Similarly, the proposed project would not divide the mobile home park communities to the north, since the large majority of mobile homes in these parks located north of the proposed improvements would remain. As discussed in the FEIR/FONSI, the proposed highway improvements would result in two fuIl acquisitions and four partial acquisitions of residential properties (totaling 18 units), and the displacement of 67 mobile homes for Altemative 7 (the Preferred Alternative). At an average of four persons per household in the proposed project area (source: 2000 United States Census), the total number ofpeople displaced would range from about 340 persons within the project area. Considering the relatively small proportion ofpersons likely to be displaced, the proposed project would not result in a substantial change in the distribution of the population in the project area or the City of Anaheim. Conclusion. Only I full residential property acquisition, 3 partiat residential acquisitions, and acquisition of 66 mobile home spaces would result from the proposed project. The current total number of acquisitionVrelocations is similar to but less than the total number of acquisitions stated the FEIR/FONSI. Therefore, the potential community character and cohesion effects ofthe proposed project are less adverse than described in the FEIR/FONSI. V.O Environmental Justice FEIRVFONSI Analysis. As discussed within the FEIR/FONSI, the population of the two census tracts in the project area is characterized by substantial proportions of both minority and low- income persons based on 2000 Census data. The proportions ofthes€ groups in the project area are much greater than in either the City of Anaheim or Orange County. It has been documented that the proposed project would have some adverse effects on all segments of the population, including minority and low-income population groups. These effects would include air emissions, residential property acquisitions and displacements, temporary construction-related impacts, and traffic noise impacts once the highway improvements are completed. Project planning and development efforts have also been undertaken to avoid or minimize potential adverse effects of the proposed highway improvements on the community. The proposed project had the least number of potential impacts of all the altematives analyzed in the FEIR/FONSI, including fewer residential partial acquisitions and displacements than the other altematives evaluated. l6 ---PAGE BREAK--- The proposed proj ect would likely result in some direct and indirect benefits to all project area residents, including minority and low-income populations, by improving transportation access, mobility, and safety. The entire community would be afforded a transportation facility that operates more efficiently and safely. Conclusion. The census data remains valid and the community is stable, in tJrat there are no changes to the demographic characteristics of the study or the project scope, and the potential environmental justice effects described in the FEIR/FONSI would remain unchanged. V.P Traffic and Transportation/Pedestrian and Bicycle Facilities FEIR/FONSI Analysis. According to the FEIR/FONSI, the construction of the proposed project would result in temporary impacts. Construction of the proposed project could directly affect traffic along Haster Street due to construction activities and lane closure. Temporary relocation of existing bus stops along Haster Street would be required. In additioru traffic delays associated with project construction could also indirectly affect nearby roadways and intersections. Although there are no existing or planned bike paths in the project area, pedestrian access in the area could also be limited during construction activities during the construction of the new sidewalks and street widening. However, such impacts would be considered temporary, as access to local residences will be maintained throughout the project construction, and alternative routes for both vehicles and pedestrians would be provided. As a result, the FEIR/FONSI has determined that these temporary traffic impacts were not considered substantial with the implementation of a traffic management plan. Longterm impacts would result in reduced existing forecast vehicle congestion on streets within the area and would result in a beneficial effect on public transit service due to street improvements that would include new bus pads and bus stop facilities on Haster Street. Implementation of the proposed build altematives would result in improved traffic conditions over the background conditions, with all local intersections operating at acceptable LOS. lmplementation of the proposed project would result in improved traffic conditions over the background conditions, with all local intersections operating at acceptable LOS. Conclusion. Due to the passage of time and the approval of the Platinum Triangle MLLIP/PTMU Overlay Zone, existing and future forecast volumes were evaluated in a Final Technical Memorandum (Parsons Brinckerhoff 2009). The Technical Memo evaluated peak-how LOS analysis at eight intersections and link analysis for four roadway segments and was based on 2007 peak-hour counts, while the future 2035 analysis was based on the City of Anaheim General Plan build-out model for 2025. Based on the comparison of intersection LOS data, the updated Traffic Memo did not indicate greater impacts or the need for more improvements and mitigations compared to the previous analysis completed as part of the FEIR/FONSL Therefore, the conclusions made within the approved FEIR/FONSI remain unchanged and no additional mitigation measures are necessary. 17 ---PAGE BREAK--- V.Q Section 4(f) FEIR/FONSI Analysis. The approved FEIR/FONSI indicated that there was no land use in the project area that qualified as a Section 4(f) property. Conclusion. Updated land use information for the surrounding area did not identifo any new parks or recreational uses. Therefore, there are no impacts to Section 4(f) properties, and the conclusions within the approved FEIR/FONSI remain the same. VI. NEWREVISED MITIGATION MEASI.JRES The following new avoidance and minimization measures have been identified to address new regulations since approval of the FONSI. Biological Resources. The following measures have been identified to avoid or minimize potential impacts associated with migratory birds during construction. B-1 To comply with the Migratory Bird Treat Ac! monitoring of existing trees to be removed within the study must be conducted between February I and September I by a qualified biologist. This monitoring shall be conducted prior to and during construction to determine if active bird nests are present within the work area. If active nests are present, construction activities within the vicinity of the tree shall be halted until the birds (adults and juveniles) have left the nest. Hazardous Materials. The following measures have been identifred to avoid or minimize potential impacts associated with hazardous materials potentially encountered in the project area. HW-t Prior to construction, conduct LBP and chromium-based paint suweys utilizing a cedified consultant prior to demolition of any remaining mobile home structures within the project limits. According to the City of Anaheim, lead-basted paint surveys and abatement plans already exist for each structure that remains to be acquired. Test yellow traffic striping and pavement-marking for LBP and CBP prior to removal during construction. Removal and disposal of yellow traffic striping and pavement- marking material will be in accordance with SSP XE 15-300. Any leaking transformers observed during the course of the project should be considered a potential PCB hazard unless tested and should be handled accordingly. Notifu and ensure that the utility owners mark the locations of underground transmission lines and facilities, call the Underground Service alert of Southern Califomia by calling 8l l at least two working days prior to subsurface excavation. HW-2 Paleontological Resources. The following measure minimized potential effects to unknown paleontological resources where excavation extends greater than 10 feet below ground surface. HW-3 HW-4 l8 ---PAGE BREAK--- PAL-1 Prior to the completion of the PS&E, in accordance with the guidelines on the Califomia Department of Transportation (Department's) SER" Volume I, Chapter a Paleontological Mitigation Plan (PMP) will be prepared by a qualified paleontologist for inclusion in the PS&E and implemented during the excavation phase of the project for areas where excavation is required greater than 10 feet below ground surface. The PMP should generally discuss the level of sensitivity of formations encountered along the project alignment; monitoring methods for areas identified as likely to contain paleontological resources (High A- and High B-rated sediments); salvage methods and procedures; and resource collection, processing, identification, documentation, and curation activities and procedures; and make a recommendation for the preparation of a Paleontological Mitigation Report (PMR), at the conclusion of the project, that follows the Department SER Volume I, Chapter 8 guidelines. The PMP will include, but not be limited to, the following steps: A qualified paleontological monitor, working under the direction ofa qualified professional paleontologist, shall be present at the pregrade meeting to explain mitigation methods and procedures to the grading crew. The paleontological monitor shall also be present on site on a full-time basis during ground-disturbing/excavation activities in sediments with a high potential for containing paleontological resources. The monitor shall inspect cuts for fossils at all times, and shall be empowered to temporarily halt or redirect construction activities to ensure avoidance of adverse impacts to paleontological resources. The monitor shall be equipped to rapidly remove any fossil specimens encountered during excavation. During monitoring, samples shall be collected and processed to recover microvertebrate fossils. Processing shall include wet screen washing and microscopic examination of the residual materials to identiff small vertebrate remains. On encountering a large deposit ofbone, the monitor shall salvage all bone in the area using additional field staff, if necessary, and in accordance with modem paleontological techniques. All fossils collected shall be prepared to a reasonable point of identification. Excess sediment or matrix shall be removed from the specimens to reduce the bulk of the material and the storage cost. Itemized catalogs of atl materials collected and identified will be provided to a museum repository along with the specimens. A PMR signi$ing completion of the PMP shall be prepared and submitted to the Lead Agencies and the institutional repository. The PMR shall discuss monitoring methods, the results of the monitoring effort, and the significance of any recovered resources, and shall include the fossil catalog. All fossils collected during this work, along with the itemized inventory of these specimens and the PMR, shall be deposited in an established institutional repository, such as a museum, for permanent curation and storage.
