BACKGROUND <br /> The adopted Staples Ranch EIR identifies a number of roadway improvements required <br /> to mitigate the impacts of the Staples Ranch development, including the opening of <br /> Stoneridge Drive to El Charro Road. The most significant of these, which are included in <br /> the City's approved CIP, are as follows: <br /> 1. Installation of Stoneridge Drive traffic signals at Newton Way, Guzman Parkway, <br /> and Trevor Parkway (CIP 115036). <br /> Status —Construction nearing completion. <br /> 2. Construction of intersection improvements at Stoneridge Drive arid Santa Rita <br /> Road (CIP 115034). <br /> Status — Construction underway with completion anticipated in early September <br /> 2013. <br /> 3. Installation of noise attenuating pavement on Stoneridge Drive from Trevor <br /> Parkway to Santa Rita Road (CIP 125024). <br /> Status— Subject of this report. <br /> Installation of noise attenuation pavement consists of resurfacing approximately <br /> 528,000 square feet of roadway pavement on Stoneridge Drive from Santa Rita Road <br /> east to Trevor Parkway with Rubberized Hot Mix Asphalt (RHMA). <br /> Funds for part of the project are programmed in CIP 125024 and are provided by <br /> Alameda County Surplus Property Authority. The objective of this project is to reduce <br /> the traffic noise using Rubberized Hot Mix Asphalt (RHMA). In the past, the City has <br /> utilized Open-Graded Hot Mix Asphalt for noise attenuating purposes because of its <br /> lower cost. However, the cost of RHMA has decreased significantly so staff is <br /> recommending its use on this project because it very effectively reduces traffic noise <br /> and has longer service life. In addition, this product uses crumb rubber from used <br /> automobile tires that would otherwise end up in a landfill. In total this project will divert <br /> approximately 12,225 used tires from the landfill. <br /> This construction method involves grinding/milling the edges of the existing pavement, <br /> and placing a new surface course (RHMA) of 1.5" thickness of rubberized asphalt on <br /> top of the existing pavement. The overlay on Stoneridge Drive will be complete and <br /> ready for the opening of Stoneridge Drive Extension in fall of 2013. <br /> The other component of this project includes the overlay of approximately 150,000 <br /> square feet of roadway on Vineyard Avenue between First Street and Bernal Avenue <br /> with conventional Hot Mix The construction method is very similar in that it involves <br /> milling the old surface before the new overlay is installed. But in the case of Vineyard <br /> Avenue, the milling will not be limited to the edges of the street. Instead, the milling on <br /> this street will be variable thickness designed to re-profile the street to reduce the <br /> Page 2 of 3 <br />
