Supplement to JARPA - Kittitas Waste Transfer Stag®n Ellensburg, Kittitas County, WA PART 6 - PROJECT DESCRIPTION 6a. Briefly summarize the overall project. You can provide more detail in 6b. The proposed project includes construction of a new Waste Transfer Station and a new Maintenance Facility for the city of Ellensburg. The conceptual design for the Transfer Station covers an approximate 25 -acre area with 4,000 feet of roadway, 51,000 square feet of stormwater ponds, 13,000 square feet of containment contact water ponds in the composting area, and six stand-alone buildings. The Maintenance Facility would be constructed on approximately 11 acres and will accommodate County road maintenance equipment and personnel. Storage of winter sand and aggregate materials would occur on site. Routine equipment maintenance would be performed at this location. The County has future plans for a fueling facility, but construction of an underground storage tank is not planned at this time. The proposed project will also include construction of a minor collector road to serve the new facilities and improvements to U.S. Highway 97. Approximately 46 percent of the site (23 acres of 50.58 -acre parcel) will be covered with impervious surfaces after project construction. The impervious surfaces will consist of approximately 21.5 acres of asphalt and approximately 1.6 acres of facility buildings. 6b. Describe the purpose of the project and why you want or need to perform it. Transfer Station. The purpose of the new Transfer Station is to replace the existing Transfer Station in Ellensburg to address existing facility limitations and support a growing community. The relocated transfer station would serve both county residents and commercial haulers. The existing facility handles solid waste, recyclables, moderate risk waste, and makes compost from yard waste. The existing transfer station and composting site is located adjacent to Wilson Creek within the 100 -year floodplain. Due to its low elevation relative to the surrounding floodplain, the existing facility floods during spring thaw and heavy rain events impacting access roads, unloading areas, and operational areas. In addition to the customer access and operational challenges associated with frequent seasonal flooding, the existing facility is also space constrained. The small size of the facility results in Long customer queuing times and potentially unsafe conditions within the small unloading and processing areas. The projected population growth and solid waste management needs of Kittitas County, combined with existing facility challenges and limitations, requires construction of a new solid waste transfer station at a new Location. A new location was chosen by an extensive site screening and selection process. The new transfer station will be designed to address existing facility limitations and support a growing community. Maintenance Facility. The Maintenance Facility would replace the existing Lower County Public Works Maintenance Facility. That facility is regularly flooded and has become too small to serve
