In addition this project also had several residential areas near the project corridor, requiring the inclusion of I-5 in the traffic noise model. There is also a substantial level of heavy truck traffic in this area, further increasing noise levels. Finally, the community was very active on this project and reviewed all aspects of the proposed interchange. The final report recommended noise walls for a large manufactured home park located along the I-5 corridor, just south of the interchange.

Fred Hill Materials, Shine Washington

Three studies of the noise impacts of a large sand and gravel operation. The first was an extensive study of the noise impacts of an existing 1 million TPY sand and gravel operation, the second study was an analysis of the effects of the excavation activities moving to a new nearby area. The third determined the noise impacts of building a ship-loading facility on Hood Canal.

To determine future noise levels when the mine’s working face is moved the 1/3 octave band noise signatures of the mining machinery were measured and input in the Environmental Noise Model. The third study (Pit-to-Pier Project) used the CADNA A noise model. All the studies indicated that the existing operations did not exceed State or County noise standards during periods of normal meteorology. In the second study, the Proposal to relocate the working face was found to generate less noise than the current operations.
