David Evans and Associates, Inc./Oregon and Washington State DOTs, Portland, Oregon and Vancouver, Washington

The Columbia River Crossing project is a comprehensive, long-term transportation solution that addresses congestion, safety, and mobility problems on I-5 between Portland, OR and Vancouver, WA. Essential elements of the five-mile project include: replacement of the I-5 bridge, a light rail extension to Vancouver, rebuilding five closely-spaced interchanges, wider pedestrian and bicycle paths, and electronic tolling. Over the five years we have been involved, MM&A has performed traffic, bus and light rail noise analyses. We recommended sound walls in both states; requiring two different reasonability and feasibility analyses. We worked with the project environmental team and met with local residents, the U.S. Forest Service, and bicycle and pedestrian advocates on noise impacts related to the project.

Fern Valley Interchange Project, Phoenix, OR

Oregon Department of Transportation

This new interchange planned for I-5 near Medford has a unique diamond type intersection crossing. The crossing is shown to the right. The traffic drives on the wrong side of the road, making it easier for traffic to access the I-5 ramps and maintaining a smother traffic flow. 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. In the first two studies simultaneous 24-hour measurements were taken at 6 locations and the results were compared to the King County Noise Code. 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.
