4.8 Noise tracks would be reduced to approximately 80 dBA when a train horn blows. However, this noise level would remain in excess of City noise standards as established in Section 18-312 and 18-313 of the Municipal Code by approximately 15 dBA for instantaneous noise. As such, this impact would be considered potentially significant. Implementation of the mitigation measures provided above (MM4.8-5 and MM4.8-6) will reduce potential noise levels at sensitive receptors associated with interior and exterior communal and private spaces but not to levels beneath the standards set in the City's Municipal Code. In addition to the aforementioned mitigation measures, the following mitigation measure would be implemented, MM4.8-8 The City shall provide a written statement to each applicant for projects located within 400 feet of the SCRRA tracks that shall be provided for each residential unit and resident, noting them of potential noise and vibration issues associated with the railroad tracks, including the following: Notice ofDisclosure Each owner's [or renter's] interest is subject to the fact that trains operate at different times of the day and night on the railway tracks immediately adjacent to a prelect site; and that by accepting the conveyance of an interest [or lease agreement] in that project, owner for renter] accepts all impacts generated by the trains. Posting ofNotice ofDisclosure in each residential unit Prior to offering the first residential unit for purchase, lease, or rent, the properly owner or developer shall post a copy of the Notice of Disclosure in every unit in a con picuous location. Also, a copy of the Notice of Disclosure shall be included in all materials distributed for the Preject, including but not limited to: the prospectus, informational literature, and residential lease and rental agreements. Although the above mitigation measure would reduce impacts, it would not serve to fully mitigate the potential impact to nearby residents of the Transit Zoning Code (SD 84A and SD 84B). However, it should also be noted that in accordance with the Final Rule for the Use of Locomotive Horns at Highway -Rail Grade Crossings, as established by the FRA, local jurisdictions have the ability to prevent trains from using their horns at at -grade crossings through the establishment of Quiet Zones. The establishment of a Quiet Zone involves the installation of additional design features that would limit potential vehicle and pedestrian conflicts with moving trains, including four -quadrant gates, advance warning signs, mountable curb medians with channelization devices, programmed enforcement, photo enforcement, and public education and awareness. The City of Santa Ana is currently pursuing the establishment of a Quiet Zone within the City; however, until such time, the use of a train horns would be considered to have a significant and unavoidable impact on sensitive receptors developed as part of the Transit Zoning Code (SD 84A and SD 8413).
