BACKGROUND <br /> In 2012, the Metropolitan Transportation Commission (MTC) began a coordinated call <br /> for projects under the One Bay Area Grant Program, which consists of two Federal <br /> Grant Programs: the Surface Transportation Program (STP) and the Congestion <br /> Management Air Quality (CMAQ). The City received $832,000 from OBAG (Cycle I) <br /> funds to rehabilitate Valley Avenue and Hopyard Road under project CIP No. 155026. <br /> Construction of this project was completed in 2017. <br /> On November 18, 2015, MTC adopted the funding and policy for the second round of <br /> the One Bay Area Grant Program, known as OBAG 2 or OBAG (Cycle II). OBAG 2 <br /> funding is projected to total $916 million to fund projects from 2017-18 through 2021- <br /> 2022. The OBAG 2 program is divided into a regional program ($530 million) managed <br /> by MTC and a county program ($386 million) managed by the nine Bay Area <br /> Congestion Management Agencies (CMAs). <br /> In order to secure the funding, it was required that City Council adopt a resolution <br /> authorizing the filing of an application for OBAG-LSR program funding, committing the <br /> necessary non-federal fund match, with a statement assuring completion of the project. <br /> On June 20, 2017, City Council adopted Resolution No.17-950, authorizing the filing of <br /> an application for federal OBAG-LSR. On March 20, 2020, staff received approval from <br /> the CA Department of Transportation to proceed with the construction of this project <br /> with $1,095,000 available in grant funds, which is an increase from the original amount <br /> of$720,000 in grant funds. <br /> DISCUSSION <br /> This project consists of resurfacing approximately 930,000 square feet of roadway <br /> surface on the streets listed in the table below. Depending on the condition of the street, <br /> one of the four following pavement rehabilitation methods is used. (The column on the <br /> right of the table indicates the treatment that will be used on each street section.) See <br /> Attachment 2 for a map of the locations. <br /> Overlay (OL): This construction method involves cold-plane milling (grinding) the edges <br /> of the existing pavement and placing a new surface course of 1.75 inches of new hot <br /> mix asphalt (HMA) over the top of the existing pavement. <br /> Overlay with Fabric (OL/F): This construction method involves grinding the edges of the <br /> existing pavement and placing a layer of paving fabric on the pavement prior to applying <br /> a new surface course of 1.75 inches of new asphalt concrete over the top of the existing <br /> pavement. The paving fabric is needed when the existing pavement has cracking <br /> caused by heating and cool cycles. The paving fabric "bridges" these cracks that are <br /> only in the surface layer. Without the fabric, the cracks would quickly propagate to the <br /> surface of the new pavement, known as "reflective" cracking. <br /> Pavement Milling and Overlay (Mill/OL): This construction method involves the removal <br /> of the existing asphalt concrete surface layer of the entire street surface by cold-plane <br /> milling, then applying of 1.75 inches HMA over the street surface. The milling or grinding <br /> of the entire street surface is necessary on streets where performing an OL would raise <br /> the crown and increase the cross slopes, particularly along the parking lane, to an <br /> unsatisfactory level. <br /> Page 2 of 4 <br />
