they needed the parking on Vineyard Avenue when large events occur on the property, citing the lack of parking on-site. Therefore, plans include the installation of signage, which will impose a 4-hour parking limit. The 4-hour parking limit will be brought back to City Council for approval prior to establishment of the parking restriction. Sauterne Way Landscaping At the November 1, 2005 City Council meeting, Mr. Mark Posson, a resident of Chardonnay Drive, requested City Council consider including Sauterne Way in the landscaping design for the Vineyard Avenue paving project. Staff developed a series of solutions to mitigate these concerns. Sauterne Way is currently striped for one-way traffic, and the request was to replace the striping with landscaping. Based on a variety of factors, including the Fire Department's concern with removing ingress and egress during an emergency, City Council on May 2, 2006, directed staff to not include landscaping improvements on Sauterne as part of the project. Sound Attenuating Pavement Alternative Previously, local residents requested that City staff research and include a bid alternative item for "rubberized asphalt concrete" as a means for reducing traffic noise in the area. Rubberized asphalt absorbs road noise and can reduce noise levels from 3-7 decibels, dependent on traffic speeds and the surrounding topography. Another sound attenuating pavement is an Open Graded Mix Design. The Open Graded Mix Design uses a lower percentage of smaller size aggregates in favor of the more uniform sized large aggregates, which promotes air voids in the pavement. The sound attenuating property of both rubberized asphalt and open graded mix is attributed to its void content. The voids in the pavement capture vehicle tire sound and muffle it, as compared to densely-graded asphalt mixes that have fewer voids and a flatter surface that reflects sound rather than absorbs sound from passing vehicles. In researching this subject matter, the Arizona Department of Transportation has had an ongoing program to study noise reduction mitigation measures for transportation corridors. Such noise reducing measures included the use of noise barriers (sound walls), sound attenuating pavements, and traffic management. One finding of the Arizona study was: Clearly, air-void composition (of asphalt pavement) is a significant factor in reducing noise. Studies are currently inconclusive about whether significant acoustical benefit accrues due to the rubber content of the surface, laid according to current hot-mix specifications. This finding was corroborated by a California study of Highway 80. The sound attenuating properties of rubberized asphalt pavement are due to the "open-graded" characteristics of the pavement, not the inclusion of rubber in the asphalt mix. In comparing open graded mix with rubberized asphalt, there are additional challenges with using rubberized asphalt. Rubberized asphalt has stricter quality control issues with regard to temperature and placement. Because of its rubber content, raking, moving, and shaping the rubberized asphalt, once it is laid on the roadway surface, becomes difficult, often affecting the pavement surface and finish qualities. This is further complicated on local streets where pavement has to be moved and placed in and around irregular features such as curb returns, median islands, left turn pockets, Page 3 of 5
