9. ENVIRONMENTAL REPORT TABLE 9.4.8-1 Specifications of Vehicles and Equipment Used During Typical Project Construction Activities MWMC Facilities Plan, Eugene-Springfield Vehicle/ Approximate Equipment Use/Location GVW (pounds) Capacity Nature of Trips Backhoe Digging trenches -- N/A Brought once to site; at site for duration of construction Hydraulic Loading and 80,000 + N/A Brought once to site; at site for forklifts unloading equipment duration of construction Note: Materials will be transported to the site on a schedule that will be determined at a later date based on construction contracts and project needs. As the primary access route to the site, Beltline Highway and River Avenue will likely experience the greatest traffic impacts from construction vehicles and workforce transport. As previously noted, most construction traffic is expected to enter and leave the site via the Beltline/River Avenue on and off ramps. Construction traffic could also enter the site via the Beltline/River Road/River Avenue interchange. Therefore, the Beltline/River Road/River Avenue area could also experience traffic impacts from the construction vehicles and workforce transport. As noted above, trucks will be used to deliver construction equipment and materials. Some of these trucks will have a GVW of the legal load limit of 80,000 pounds. Heavy equipment will be transported to the project site using a semi-truck and lowboy transporter designed for heavy loads (i.e., multiple axles). The largest vehicles would likely be D8 and D9 bulldozers weighing approximately 100,000 and 400,000 pounds, respectively. These vehicles exceed the legal load limit and would require a permit. Cranes would be required to install new equipment at the WPCF. Cranes would be within the legal load limit of 80,000 GVW. They would be brought in on six axles with rubber tires and would drive on the highway. Movement of the heavy equipment transporters will have a short-term impact on traffic along the Beltline Highway and other roadways used along the transporter route. Construction Accidents Although the additional vehicular and construction traffic attributable to the project could increase the risk of accidents, it is anticipated that the overall accident rate or pattern would be similar to existing conditions. Mitigation Traffic control would be written into contract specifications, which would address traffic safety. Flaggers would be used for equipment transporter access and turn-around on an as- needed basis. 9.4.9 Cultural Resources According to the Eugene Cultural Resource Inventory Program (Eugene Planning and Development Department, 2003), the River Road area in Eugene has not been surveyed for historical resources. However, the MWMC project site is highly disturbed from previous MWMC_9.0_REV14.DOC 9-17
