NOISE Also See HM-2 and HM-3 N-1 To reduce potentially significant temporary noise resulting from blasting activities the following is required: 1. construction, a noise and vibration monitoring plan (NVMP) shall be prepared, showing the locations where monitoring shall occur over the duration of the blasting and/or removal of rock debris and outlining vibration monitoring methodology, equipment, duration, report process, vibration limits, exceedance protocol and complaint resolution process. 2. The operator shall design the blasting charge such that the overpressure noise level does not exceed 135dB and the vibration level does not exceed 0.5 PPV in/sec at the nearest sensitive receptor and ensure that blasts DO NOT occur closer than 50 feet from a sensitive receptor. 3. Sound Barriers should be used and best practices methodologies for rock removal shall be employed. Sound Barriers shall be at least 16ft. tall and should block any line of sight between the blasting areas and second story residences. 4. In locations where rock removal is required closer than 100ft. to Page 6

7 residential homes, the project shall use a non-explosive option, such as an excavator or non-explosive agent for removal of large rock as outlined in the Blasting Noise Study. N-2: To reduce potential of temporary noise and air quality nuisances that result from construction, the following items shall be listed as "General Notes" on the construction drawings: 1. Construction activity and equipment maintenance is limited to the hours between 7:00 a.m. and 7:00 p.m. Per Zoning Ordinance, Noise Control, Section , it is unlawful for any persons between the hours of 7:00 p.m. of any day and 7:00 a.m. of the following day, or on a legal holiday, or on Sundays to erect, construct, demolish, excavate, alter or repair any building or structure in a manner as to create disturbing excessive or offensive noise. If any deviation from the construction hours are deemed necessary, a formal request to the building inspector identifying why this must occur and the time frame needed along with necessary provision to mitigate noise impact. The approval of this request is subject to the approval of the Official. 2. construction noise shall not exceed 80 dba in residential zones in the City. 3. Construction routes are limited to City of Perris designated truck routes or otherwise approved by the City Engineer. 4. Water trucks or sprinkler systems shall be used during clearing, grading, earth moving, excavation, transportation of cut or fill materials and construction phases to prevent issuance of any.

Alternative materials and methods of construction may be permitted provided such alternatives are demonstrated to the satisfaction of the city's building official to be equivalent to those described in this chapter. CULTURAL RESOURCES CR-1: In accordance with Section of the California Health and Safety Code, if human remains are found during ground-disturbing activities, no further excavation or disturbance of the site or any nearby area reasonably suspected to overlie adjacent remains shall occur until the County Coroner has determined, within two working days of notification of the discovery, the appropriate treatment and disposition of the human remains. The County Coroner shall be notified within 24 hours of the discovery. If the County Coroner determines that the remains are or believed to be Native American, s/he shall notify the Native American Heritage Commission (NAHC) in Sacramento within 24 hours. In accordance with Section of the California Public Resources Code, the NAHC must immediately notify those persons it believes to be the most likely descended from the deceased Native American. The descendants shall complete their inspection within 48 hours of being granted access to the site. The property owner will then determine, in consultation with a designated Native American representative, the final disposition of the human remains (California Code of Regulations, Title 14, Section [e]). CR-2: The Project developer shall retain a professional archaeologist that meets the Secretary of the Interior's Professional During groundwork phase of construction During groundwork phase of Page 9 Planning Division Planning Division

10 Qualification Standards for Archaeology (U.S. Department of lnterior, 2012) including an advanced degree in anthropology, archaeology, or a related field, and the local experience necessary to evaluate the specific Project, and as approved by the City of Perris prior to the issuance of grading permits. The professional archaeologist must also meet the minimum criteria for recognition by the Register for Professional Archaeologists (RPA) although membership is not required. The task of the archaeologist shall be to monitor the initial ground-altering activities at the subject site and off-site Project improvement areas for the unearthing of previously unknown archaeological and/or cultural resources. Selection of the archaeologist shall be subject to the approval of the City of Perris Director of Development Services and no grading activities shall occur at the site or within the off-site Project improvement areas until the archaeologist has been approved by the City. The archaeological monitor shall be responsible for maintaining daily field notes and a photographic record, and for reporting all finds to the developer and the City of Perris in a timely manner. The archaeologist shall be equipped to record and when necessary, recover cultural resources that may be unearthed during grading activities. construction The archaeologist shall be empowered to temporarily halt or divert grading equipment to allow recording and removal of the unearthed resources. In the event that archaeological resources are discovered at the Project site or within the off-site project improvement areas, the handling of the discovered resources will differ. However, it is understood that all artifacts with the exception of human remains and related grave goods or sacred/ceremonial objects belong to the property owner. All artifacts discovered at the development site shall be inventoried and Page 10

11 analyzed by the professional archaeologist. If any artifacts of Native American origin are discovered, all activities in the immediate vicinity of the find (within a 100-foot radius) shall stop and the project proponent and project archaeologist shall notify the City of Perris Planning Division, the Pechanga Band of Luiseno Indians, the Soboba Band of Luiseno Indians, and any other tribes identified by the Native American Heritage Commission (NAHC) as being affiliated with the area tribes. A designated Native American observer from one of the tribes identified by the NAHC as being affiliated with the area shall be retained to help analyze the Native American artifacts for identification as everyday life and/or religious or sacred items, cultural affiliation, temporal placement, and function, as deemed possible. The significance of Native American resources shall be evaluated in accordance with the provisions of CEQA and shall consider the religious beliefs, customs, and practices of the Luiseno tribes. All items found in association with Native American human remains shall be considered grave goods or sacred in origin and subject to special handling. If the Project developer, Project archaeologist, and Native American observer cannot agree on the significance of, avoidance of, or mitigation for such resources, these issues shall be presented to the Planning Manager for determination. The Planning Manager shall make the determination based on the information submitted by the Native American observer, the religious beliefs, customs and practices of the Native American observer s tribe, and the provisions of the California Environmental Quality Act regarding tribal cultural and archaeological resources. Notwithstanding any other rights available under law, the decision of the Planning Manager shall be appealable to the Planning Commission and/or City Council. Consistent Page 11

12 with California Public Records Code Section (b) and Assembly Bill 52 (Chapter 532, Status of 2014) avoidance shall be the preferred method of preservation for tribal cultural resources and archaeological resources. Native American artifacts that are relocated/reburied at the Project site would be subject to a fully executed relocation/reburial agreement with the tribe or band of the Native American observer. This shall include measures and provisions to protect the reburial area from any future impacts. Relocation/reburial shall not occur until all cataloging and basic recordation have been completed. Native American artifacts that cannot be avoided or relocated at the Project site shall be prepared in a manner for curation at an accredited curation facility in Riverside County that meets federal standards per 36 CFR Part 79 and makes the artifacts available to other archaeologists/researchers for further study such as University of California, Riverside Archaeological Research Unit (UCR-ARU) or the Western Center for Archaeology and Paleontology. The archaeological consultant shall deliver the Native American artifacts, including title, to the accredited curation facility within a reasonable amount of time along with the fees necessary for permanent curation. Non-Native American artifacts shall be inventoried, assessed, and analyzed for cultural affiliation, personal affiliation (prior ownership), function, and temporal placement. Subsequent to analysis and reporting, these artifacts will be subjected to curation or returned to the property owner, as deemed appropriate. Once grading activities have ceased or the archaeologist, in consultation with the designated Native American observer, determines that monitoring is no longer necessary, monitoring activities can be discontinued following notification to the City of Perris Planning Division. A report of findings, including an Page 12

13 itemized inventory of recovered artifacts, shall be prepared upon completion of the steps outlined above. The Project archaeologist shall prepare a final archaeological report within sixty (60) days of completion of the Project. The report shall follow Archeological Resource Management Reports (ARMR) Guidelines and City of Perris requirements, and shall include at a minimum: a discussion of the monitoring methods and techniques used: the results of the monitoring program, including any artifacts recovered: an inventory of any resources recovered: final disposition of the resources: and, any additional recommendations. A final copy of the report shall be submitted to the City of Perris, Project Applicant, the Eastern Information Center (EIC), and the Pechanga Band of Luiseno Indians, the Soboba Band of Luiseno Indians, and the tribe or band of the Native American observer. CR-3: Should paleontological resources be found during ground-disturbing activities for the Project, a qualified Paleontologist shall be retained by the Project Developer to evaluate the discovery. If a fossil discovery occurs, grading shall be diverted around the area until the Paleontologist can survey the area, evaluate, and remove the discovery. Any fossils recovered during the development, along with their contextual stratigraphic data, shall be donated to the City or other appropriate institution with an educational and research interest in the materials. The Paleontologist shall prepare a report of the results of any findings as part of a testing or mitigation plan following accepted professional practice. Any paleontological work at the site shall be conducted under the direction of a qualified Paleontologist. During groundwork phase of construction Planning Division Page 13
