shortfall of $652,155. Staff recommends the transfer of$652,155 from various CIP <br /> projects (as outlined in the recommendations above) to complete funding for this <br /> project. The project funding includes Gas Tax, SB-1, Measure B/BB, and Measure F. <br /> The funding and anticipated project expenditures are detailed in Attachment 1. <br /> BACKGROUND <br /> The City has two annual projects designed to maintain roadway infrastructure: the <br /> Annual Street Resurfacing and Preventative Maintenance Project and the Annual Slurry <br /> Seal Project. The first project resurfaces various roadways by overlaying the existing <br /> pavement with a new layer of asphalt concrete, while the other project slurry seals a <br /> different set of roadways. The resurfacing project is considered a street reconstruction <br /> project, while the slurry project is a preventative maintenance project. Together, these <br /> projects are designed to maintain the city's roadway pavement condition. <br /> The Annual Street Resurfacing and Preventative Maintenance Project has two <br /> components: resurfacing/reconstructing work and preventative maintenance work. The <br /> street resurfacing component includes installing a new layer of asphalt concrete over <br /> the existing pavement, repairing distressed pavement areas, crack sealing, adjusting <br /> manholes and water valve boxes to grade, installing pavement markers, striping, and <br /> installing traffic detector loops. The roadway preventative maintenance component <br /> includes preparatory work for the upcoming Annual Street Slurry Seal Project, CIP No. <br /> 22504. The preventative work will include sealing pavement cracks and repairing <br /> pavement in isolated distressed areas. This preparatory work is required prior to the <br /> slurry sealing operation but is included as part of the paving project for both cost <br /> savings and optimal results. The slurry seal project is scheduled to begin construction <br /> immediately after the completion of this project's preventative maintenance component. <br /> DISCUSSION <br /> The first component of the project consists of resurfacing/reconstructing approximately <br /> 1 million square feet of pavement on the streets listed in the table below. The streets <br /> which will be reconstructed are also shown graphically in Attachment 2. The roadway <br /> reconstruction method utilized is dependent on the condition of the existing street <br /> section. The different reconstruction methods are described below. <br /> 1. Overlay (OL): This reconstruction method involves milling the edges of the <br /> existing pavement and placing a new surface course of 1.5 to 1.75 inches of new <br /> asphalt concrete over the top of the existing pavement. Milling the edges is <br /> necessary to conform the new overlay with the existing curb and gutter. <br /> 2. Overlay with Fabric (OUF): This reconstruction method involves milling the <br /> edges of the existing pavement and placing a layer of paving fabric on the <br /> surface of the existing pavement prior to applying a new surface course of 1.75 <br /> inches of new asphalt concrete over the top of the fabric. Paving fabric is needed <br /> when the existing pavement has cracking caused by swelling and shrinking <br /> associated with heat and cool cycles. The paving fabric "bridges" these cracks <br /> that are only in the surface layer. Without the fabric, the cracks would quickly <br /> propagate to the surface of the new pavement. This is known as "reflective" <br /> cracking. <br /> Page 2 of 5 <br />
