RFP #21-017: On -Call Environmental Review Services for the CHAMBERS Housing Division City of Santa Ana Community Development Agency GROUP Dudley Street Multi -Family Residential Project, Pomona, CA Prepared an air quality, energy, and GHG emissions impact analysis and a noise impact analysis for the development of 152 townhomes at 1440 Murchison Avenue. The air quality, energy and GHG report analyzed the regional construction and operational air emissions with the CalEEMod model and utilized the SCAQMD Look -Up Tables for the localized analysis. The analysis found that with adherence to State and SCAQMD regulations that air quality, energy and GHG impacts would be less than significant. The noise report analyzed construction noise levels with the FHWA RCNM, utilized the FHWA-RD-77-108 model to analyze the offsite roadway noise impacts from the project and utilized the SounclPlan model to analyze the Freeway noise impacts to the proposed townhomes. The analysis found through implementation of Project Design Features that included sound walls and upgraded windows and doors that noise and vibration impacts would be less than significant. Archstone Huntington Beach at Edinger Project, Huntington Beach, CA Prepared an air quality and global climate change impact analysis for the development of four story residential apartment building with 510 units, a central five story parking structure and amenities located on an 8.5 acres at Edinger Avenue and Gothard Street that is within the Beach and Edinger Corridors Specific Plan (BECSP). The analysis utilized CalEEMod to analyze the project's regional criteria pollutant and GHG emissions and SCAQMD's Mass Rate LST Look- up Tables to analyze the project's local criteria pollutant impacts from construction activities. With implementation of the required air quality and GHG mitigation measures provided in the BECSP, no significant construction or operational impacts were found. Washington Avenue Lot Well & Facility Project, Santa Ana, CA Prepared an air quality and GHG emissions analysis and a noise impact analysis for the development of a water well, well building and chemical building located on the northwest corner of Penn Way and Washington Avenue. The air quality and GHG report analyzed the regional construction and operational criteria pollutant and GHG emissions with the CaIEEMod model and utilized the SCAQMD Look -Up Tables for the localized analysis. The analysis found that the project would result in lessthan significant air quality or GHG emissions impacts. The noise report analyzed construction noise levels with the SounclPlan model that utilized reference noise measurements taken during active well construction activities and from the FHWA's Road Construction Noise Model (RCNM). The noise modeling found that there would be a significant noise impact during the well drilling phase of construction and the proposed mitigation of a minimum 8-foot high wall around the project site was quantified with the SounclPlan model, which showed the mitigation was adequate to reduce construction noise to within City noise standards. 813 N Euclid Street Gas Station Project, Santa Ana, CA Prepared an air quality, energy, and GHG emissions analysis and a noise impact analysis for the development of a gas station with eight fueling positions and a 3,045 square foot convenience store. The air quality and GHG report analyzed the regional construction and operational criteria pollutant and GHG emissions with the CalEEMod model and utilized the CAPCOA Gas Station Guidelines to calculate the VOC emissions created from the transfer and dispensing of gasoline. The SCAQMD Look -Up Tables were utilized for the localized analysis and the SCAQMD's Risk Tool V1.103 was utilized to calculate the cancer risk from gasoline dispensing activities at the nearby homes. The analysis found that the project would result in less than significant air quality, energy or GHG emissions impacts. The noise report analyzed construction noise levels with the FHWA RCNM, utilized the FHWA-RD-77-108 model to analyze operational vehicular noise and utilized reference noise measurements of similar gas station facilities and typical noise propagation rates to analyze noise impacts from the proposed project to the nearby homes. A significant nighttime noise impact was found to be created by the proposed air/water machine and mitigation was provided that restricted the operation of the Air/Water machine during the nighttime noise sensitive hours of 10 p.m. to 7 a.m. In addition, the noise analysis analyzed construction and operation -related vibration impacts, which found that the proposed pile driving during construction would create a significant vibration impact. Mitigation was provided that required the use of sonic pile drivers. Est t A-34 �ilP 1979 www.chambersgroupinc com
