Civil/Grading Sheet(s): N/A Ref. Detail(s): N/A Inspection(s) Performed: 0 Grading Report Observations: Arrived on site to find pool sides had been excavated and dimensions widened and the deep end of the pool filled in with native materiel. The contractor informed the inspector that they had not covered the fill placed the previous day from rain, and that the materiel had turned to mud due to after hours rain. They stated that they had removed the mud and replaced and backfilled the deep end using native cuttings from their excavation activities, then compacted the materiel using a tracked front end loader with a full bucket. Probing of this placed filled using a steel soil probe indicated that this fill had not been adequately compacted, and in the deepest part penetrated over a foot, with water and mud visible on the bottom few inches of the probe. Contractor was advised and elected to remove this wet materiel and replace it with dryer native materiel. This was done in a single lift and compacted using the same method. Testing with the nuclear gauge produced consistently low values for both dry density and moisture. This materiel was then re -worked using a jumping jack, and while numbers were improved, still returned consistently low. Contractor elected to scarify the top 6" of the lift, mixing and wetting this material, while wetting and recompacting the lower 6" using the frontend loader. This mixed materiel was then replaced and compacted using both the loader and the jumping jack. This 12" of materiel was then tested using the nuclear gauge, and while slight improvement was measured, the density was likely still short of 95%. The top 6" was then tested, and found to have improved dry densities that would likely meet compaction requirements. The contractor then once again removed the upper 6", and compacted the lower 6 inches with the jumping jack. This materiel was then tested, and found to have likely adequate compaction values. This test result has been attached, and at the time of issue of this report, proctor results show this test as passing. The contractor was within 1' of FSG for the remaining of the pool, and was advised that they could continue placing the remaining fill and that it could be tested upon completion, but to keep lifts no greater than 6" in order to achieve adequate compaction levels.

The pool equipment is located approximately 18 inches from the nearest property line to the north. The property to the north is also a single-family residence. The properties are separated by a 7-foot concrete masonry wall and a 22-foot open space. The City of Newport Beach requires a sound test by an acoustical engineer is required to demonstrate that the noise level from the pool or spa pump is less than 55 dBA at the property line. NBMC10.26. 025. YANCHAR DESIGN & CONSULTING GROUP 2 2720 Pebble Dr. July 14, 2022 2.0 Field Measurements Measurements were made at the site on July 14, 2022 to determine the sound level of the pool equipment. The ambient noise level at the property was dominated by aircraft overflights and local traffic. The sound level measured at the CMU wall was 54.8 dBA. Inverse square law attenuation would decrease the sound level by 13 dBA at the property line. Therefore the equipment is in compliance with the requirements of the City of Newport Beach Municipal Code. A Soft dB Piccolo -II Integrating Sound Level Meter, Serial Number P0219050803 and CEL Instruments Model CEL-284/2 Calibrator, Serial Number 4/09023134, were used for the measurements.
