Construction Materials and Equipment. If the project uses aboveground mounting methods with ballasted (concrete) blocks, the amount of concrete required is subject to wind loading and engineering analysis. An estimated 33,000 cubic yards of concrete could be used to create the ballasted footings, equivalent to approximately 3,500 truckloads of concrete. The concrete is expected to be premixed. If a concrete batch plant is necessary for the site, it will only be used for onsite purposes and will be removed when construction is completed. The structural supports and other mounting materials will require an estimated 800 trucks to deliver materials to the site based on vendor estimates. Thus, a total number of truck deliveries to the site will be in the range of 4,300 for deliveries of goods and materials. The 75 MWdc anticipated to be generated from this project equates to 75,000,000 xxxxx-dc, or 347,222 solar modules of 216 xxxxx-dc each. It is estimated that the project will require up to 450 shipping containers of solar modules. Gravel and concrete for the project will be sourced in the Cle Elum area to the extent possible. Construction equipment such as backhoes, loaders, concrete trucks, and graders will likely be used. A crane may be necessary, but is typically not required. Transportation and Traffic Materials for the project (e.g., solar modules, supporting racks, foundation materials, electrical gear) will be brought to the site by truck. The trucks will travel on Interstate 90 (I- 90) and access Highway 970 by way of County roads such as Red Bridge Road (see Figure 3), and private roads such as Loping Lane and Xxxxx Road. Road service within the project area will be provided by an existing network of maintenance roads, although new maintenance roads or segments may be necessary. Road improvements will be conducted as required by the County. Road improvements are further addressed in the DA with Kittitas County. For further discussion of traffic impacts, see the Transportation section of this checklist.
