Table 18 <br />Demolition Noise Levels <br />Location <br />Leg <br />Lmax <br />Playfields at school adjacent to the northern <br />property line <br />88.8 <br />92.1 <br />Residential adjacent to the eastern property line <br />72.2 <br />74.2 <br />Residential property line 140 feet to the south <br />66 <br />69 <br />Residential property line 145 feet to the west <br />72.6 <br />75.6 <br />Residential property line 225 feet to the southwest <br />67.9 <br />71 <br />Grading <br />The noise levels that would be generated to the adjacent land uses during project grading are shown in <br />Table 19. <br />Table 19 <br />Grading Noise Levels <br />Location <br />Leg <br />Lmax <br />Playfields at school adjacent to the northern property line <br />87.3 <br />91 <br />Residential adjacent to the eastern property line <br />82.3 <br />86 <br />Residential property line 140 feet to the south <br />67.8 <br />69.6 <br />Residential property line 145 feet to the west <br />72.6 <br />74.4 <br />Residential property line 225 feet to the southwest <br />69.7 <br />71 <br />Although construction noise activities would have a temporary or periodic increase in the ambient noise <br />levels above the existing noise levels within the vicinity of the project vicinity, all construction activities <br />would be restricted to the hours allowed by Santa Ana Municipal Code Section 18-314. Therefore, <br />construction -related noise impacts are considered less than significant. However, to be conservative <br />and reduce construction noise levels at the nearest sensitive receptors, mitigation measures 2-9 listed <br />in section "XIII. a)" above would further reduce construction noise impacts to area residents. <br />Taft Elementary school to the north and multi -family residences to the east, south (south of Sunflower <br />Avenue), west (west of Flower Street), and southwest (across the Sunflower Avenue and Sakioka Drive <br />intersection) may be temporarily impacted by short-term construction noise on the site. The short-term <br />noise impacts would be associated with construction workers commuting to the site, the delivery of <br />construction materials to and from the site, ground clearing and demolition, excavation, grading, and <br />building activities. However, the construction noise would be acoustically dispersed throughout the site <br />and not concentrated in one area near adjacent surrounding sensitive land uses. Santa Ana Municipal <br />Code section 18-314 exempts noise associated with construction, repair, remodeling, or grading of any <br />real property from the noise limitations of the Municipal Code, provided that construction activities do <br />not occur between the hours of 8:00 PM and 7:00 AM on weekdays, including Saturdays, or any time <br />on Sundays or federal holidays. Because the project would be required to comply with the hours of <br />construction as defined by Santa Ana Municipal Code section 18-314 the noise levels that are <br />generated during construction would not have any significant noise impacts to area residents. <br />Legacy Sunflower Apartments Page 78 <br />Mitigated Negative Declaration — March 14, 2019 <br />751-164 <br />
