community. Subsequently, a 12 member Street Repair Review Panel (SRRP) was formed to <br />document the use of the bond proceeds. In2011, City Council approved the addition of 22 streets <br />selected in the same manner and recommended by the citizen review panel to be repaired. <br />In 2012, a second five-year bond measure was approved by Eugene voters with a prioritized list <br />of 76 street repair projects (Exhibit A) and additional funding to support bicycle and pedestrian <br />improvement projects.The list was developed using the same criteria as above and approved by <br />City Council. <br />In 2017, a third five-year bond measure for street preservation, bicycle and pedestrian <br />improvements was approved by Eugene voters. Of the $51.2 million bond, 91 road projects will <br />be completed with $5 million going towards pedestrian and bicycle infrastructure, andsafety <br />improvements. <br />Sustainable Construction <br />Since 2008, Eugene has been inthe forefront of sustainable construction and paving practices, <br />some of which include paving with warm mix asphalt (WMA), using reclaimed asphalt <br />pavement (RAP), and full depth reclamation (FDR). Production of warm mix asphalt <br />solution for the environment with noticeable reduced energy consumption and greenhouse gas <br />emissions. Exposure to fuel emissions, fumes, and odors are reduced for asphalt producers, <br />construction workers and the public. Benefits of paving with WMA are the ability to extend the <br />paving season in colder weather, longer haul distances, and better road performance. Warm mix <br />asphalt is identical to conventional hot mix asphalt, except that through a special mixing process <br />itis produced at a temperature approximately 50 to 100 degrees cooler than conventional hot mix <br />asphalt. This mixing process for asphalt aids in compaction during paving, assists in preventing <br />premature aging andslowsthe aging process of asphalt. In Eugene, all asphalt producers have <br />retrofitted their plants to produce warm mix asphalt. <br />Council set goals in 2011 for waste reduction byrequiring that the quantity of materials placed in <br />landfills be reduced. In addition to using WMA, Public Works conducted twopilot projects <br />specifying that reclaimed asphalt shingles (RAS) be used as a binder in the asphalt mix, thereby <br />keeping this material from entering the waste stream. The City continues to use warm mix <br />asphalt and in-place recycling techniques to improve the quality, environmental footprint, and <br />cost efficiency of the street bond projects. Key terms in sustainable construction practices: <br />In-Place Recycling: A process in which a large piece of equipment called a reclaimer <br />pulverizes and mixes the existing base rock and a portion of subgrade soils with dry cement <br />and water to create a cement-treated base. This process greatly reduces the use of virgin <br />materials and trucking that are needed using conventional remove-and-replace construction <br />techniques. <br />Full Depth Reclamation: When applicable, partial or full-depth reclamation (FDR) is used as <br />a cost and time-saving alternative to traditional reconstruction. Associated costs include <br />replacement of striping and pavement markings, adjustment of manholes, and other work <br />needed to return the street to normal operation. <br />13 <br /> <br />
