Part 1: Eco-Charrette Introduction and Purpose The King County Department of Natural Resources and Parks, Solid Waste Division (KCSWD) has goals for the Factoria Recycling and Transfer Station (Factoria RTS) Project that include environmental stewardship, creation of resources from solid waste, and green building principles. To meet these goals, the Factoria RTS project team is using an integrated, sustainable design process. As part of the sustainable design process, the design team conducted an Eco‐Charrette with the project team and KCSWD staff. The Eco‐Charrette consisted of two workshops: Day 1: Sustainable Design Process and Day 2: LEED Scorecard Review. The purpose of this report is to summarize the Eco‐Charrette results and include a summary of environmental site characteristics, a preliminary LEED score, and a LEED strategy to use moving forward. This report presents the sustainable design and LEED strategies evaluated during preliminary site design and layout. As design and coordination with the project team and stakeholders continue to final design, the strategies may change and evolve. The sustainable design and LEED strategies will continue to be updated and tracked through monthly progress reports. The following sections describe the project background and setting, then summarize the Eco‐ Charrette results for Day 1: Sustainable Design Process and Day 2: LEED Scorecard Review. Appendix A contains the current LEED scorecard, which includes minor updates since the Eco‐ Charrette. Appendix B summarizes the team roles and responsibilities for each LEED credit. Appendix C includes the meeting notes and the interactive Strengths, Weaknesses, Opportunities, and Threats (SWOT) summary. Project Background and Setting The Factoria RTS is one of eight County transfer stations where waste is collected, transferred into large tractor‐trailers, and subsequently hauled to the Cedar Hills Regional Landfill (CHRLF) in Maple Valley, Washington. Commercial haulers and business and residential self‐haul customers use the Factoria RTS. The Factoria RTS was constructed in the 1960s and is nearing the end of its useful life. The County intends to maintain operation of the existing transfer station during construction of its replacement on adjacent property. The new Factoria RTS will include the following features: Enclosed solid waste transfer and processing area Employee/administration facility and education center <ul style="display: flex;"><li style="flex:1">Final Eco‐Charrette Report </li><li style="flex:1">1</li></ul>Factoria Recycling and Transfer Station Scalehouse with weigh station plaza Fueling facility Maintenance shop Household hazardous waste (HHW) collection area Recycling facility Vactor truck decant area Construction of the new facilities is planned to occur in two phases to limit disruption to site operations. The first construction phase is expected to include the new Factoria RTS, administration and employee areas, a maintenance shop, fueling facility, vactor truck decant area, and access roads. The second construction phase will include a new facility for HHW and recycling functions, improved onsite and offsite access roads, new truck scales and a scalehouse facility. The Factoria RTS is situated on an approximately 8.7‐acre parcel that is constrained by steep topography, wetlands, streams, and a large utility corridor easement occupied by Olympic Pipeline high‐pressure liquid petroleum lines and Puget Sound Energy (PSE) overhead power lines. The transfer station operation and household hazardous waste (HHW) collection are contained within one large building on the site. Southeast 32nd Street terminates at the Factoria RTS entrance, where a small scalehouse is located to weigh vehicles upon entering and exiting the site. To maintain existing operations, the County purchased adjacent property northwest of the site that contains two warehouse buildings, bringing the total size of the project site to approximately 10.7 acres. The photo below is an aerial image of the site. Appendix D includes full‐page aerial snapshots of the site.

Introduction to the Sustainable Design Process The sustainable design process is an integrated process that must be implemented during planning, design, construction, and operation. The integrated process includes an outward‐in approach: Site opportunities Site constraints KC Department of Natural Resources and Parks Mission: To foster environmental stewardship and strengthen communities by providing regional parks, protecting the region’s water, air, land, and natural habitats, and reducing, safely disposing of, and creating resources from wastewater and solid waste. Energy conservation and renewable energy opportunities LEED structure Framework for cost and schedule Factoria RTS Goals:  Maintain existing operations safely and efficiently while the new facility is constructed. Day 1 of the Eco‐Charrette provided an overview of the sustainable design process, and then focused on site and energy conservation opportunities. During Day 1 of the Eco‐ Charrette the project team discussed the site starting with regional and community levels, then focused on the site itself. This approach allowed the project team to brainstorm in an open forum about opportunities and ideas, experiences, and lessons learned. It was helpful to welcome all ideas before focusing on LEED requirements, because it may be possible to innovate and include ideas that otherwise may not have been brought forth.  Architectural excellence. Design and construct a facility that will enhance the local community, achieve at least a LEED Gold rating, and tie into the overall plans for the area (trails and mass transportation facilities).  Develop the Eastgate property to potentially provide funding for the Factoria RTS project and to secure support for the Factoria RTS project from the City of Bellevue After discussing the KCSWD mission and the Factoria RTS goals, some of the key design criteria were also discussed:  Diversion. Increase waste diversion through improved public recycling opportunities and the transfer facility design. Enclosed solid waste transfer and processing area HHW collection Recycling facility Separate public and commercial users from KCSWD transfer vehicles Minimize customer time onsite Increase vehicle capacity 900 tons/day capacity (by 2042) <ul style="display: flex;"><li style="flex:1">Final Eco‐Charrette Report </li><li style="flex:1">3</li></ul>Factoria Recycling and Transfer Station 3 days’ storage capability Ability to efficiently compact waste Minimum roof clearance for collection trucks Wetland mitigation Traffic flows and site access Retaining walls/grading Trailer parking Stormwater features Sustainable features Flexibility for expansion and additional services Once the sustainable design process, guiding principles, goals, and key design criteria were discussed for the framework, the project team participated in an interactive Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis. The SWOT analysis was framed by a discussion of the built and natural environments in the context of the community and the site. The discussion also focused on energy efficiency and operations and maintenance. The opportunities and concerns resulting from this exercise will serve as a point of reference throughout design, construction, and ideally, operation of the facility, especially the operations and maintenance (O&M) discussions. While some ideas may contribute to the LEED strategies, other ideas might contribute to best management practices or “pilot” ideas where the KCSWD might choose to lead by example and test new strategies. The detailed results of the SWOT analysis are included in Appendix C as meeting notes as well as a reproduction of the flip chart notes that were used throughout the Eco‐Charrette. The Eco‐Charrette results section below includes select ideas from the SWOT analysis that could be considered with a specific LEED credit. Day 2: LEED Scorecard Review Day 2 of the Eco‐Charrette provided an overview of the LEED certification process, and then focused on each of the LEED credits using the information developed from the SWOT analysis and project team experience on LEED projects and other transfer stations in the region. The one‐page LEED scorecard that resulted from Day 2 of the Eco‐Charrette (with minor updates from follow up) is
