RFP #21-017: On -Call Environmental Review Services for the Housing Division City of Santa Ana Community Development Agency Dud ,cy yrp ryet; V''l+r ri-I AICYr..y h'rraj f.�c r, P JCrc_ii 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-IDS model to analyze the offsito roadway noise impacts from the project and utilized the Sound Plan 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. A,rffim,our. V iunringron Be:m h .0 I dirij;ci Pi ojc(t, V ii_rnrirLgr rl G�,ac Cn, CA Prepared an air quality and global climate change impact analysis for the development of four story residential apartment building with S10 units, a central five story parking structure and amenities located on an S.S acres at Edinger Avenue and Gothard Street that is within the Beach and Edinger Corridors Specific Plan (SECSP). I he analysis utilized CalEEMod to analyze the project's regional criteria pollutant and GHG emissions and SCAQMD's Mass Rate LST Look- up Tables Lo analyze Lhe projec Cs local criteria pollul-ani- impacts from construction acLivi Lies. WiLh implementation of the required air quality and GHG mitigation measures provided in the BECSP, no significant construction or operational impacts were found. "JW;a hint tcarr Avenue Lear. Well & Facility Project, Santa lama, 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 CalEEMod model and utilized the SCAQMD Look -Up Tables for the localized analysis. The analysis found that the project would result in less than significant air quality or GHG emissions impacts. The noise report analyzed construction noise levels with the SoundPlon model that utilized reference noise measurements taken during active well construction activities and from the FI IWA'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 Sound Plan model, which showed the mitigation was adequate to reduce construction noise to within City noise standards. 13 13A ur rC str"(r t V nt'S Sr irU)rl ..zr'dal@.� r ;aal"lt7 Aria. d.....-. Prepared an air quality, energy, and GHG emissions analysis and a noise impact analysis for the development of a gas s La Lion wiLh eight fueling positions and a 3,04S square fool- convenience sLore. 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. City Council Est -rofr,_ 7979 15— 139 A-34 vvww L iL i I� , ,,u r, ) i.;.r;orn 7/6/2021
