JC0726-2022-069-Vikek Facility Condition, Design Alternatives and Screening Process 3 3.0 Changes to ZOOM Platform for Presentations The consultant team has developed new meeting security protocol to avoid being “Zoom bombed” as occurred at our last meeting. You will join the meeting as a member of the public, with no ability to turn your microphone or camera on. You will be promoted to be a panelist, which will then allow you to have audio and video access to the meeting. From that point on, everything else will remain the same for you. Meeting observers (community members, staff, etc.) will remain as participants with no ability to interject audio or video unless I give them permission. 4.0. Results of Existing Solid Waste Facility Current State Condition Assessment Assessment of the Existing SWF – A high level condition assessment of the existing Solid Waste Facility at Port Townsend was completed to identify any physical condition and functional performance gaps. The results of this assessment are presented in Figure 1 below. Figure 1 – Current State Condition Assessment Report Card JC0726-2022-069-Vikek Facility Condition, Design Alternatives and Screening Process 4 JC0726-2022-069-Vikek Facility Condition, Design Alternatives and Screening Process 5 5.0 Draft Initial Facility Design Alternatives Definition Four (4) Initial SW Facility (‘facility’) design alternatives were defined based on the SW improvement objectives. These alternatives will be updated where appropriate after feedback is received from the community. The four alternatives identified are described in detail in Table 2 and defined below: • Alternative 1 – Basic Level of Service. The entry level of service for a new facility meeting basic needs. • Alternative 2 – Medium Level of Service. Meets all Alternative 1 Level of Service and adds additional service levels as indicated. • Alternative 3 – High Level of Service. Meets all Alterative 1 and 2 Levels of Service and adds additional service levels as indicated. • Alternative 4 – Current Level of Service + upgrades + operations management changes : The status quo scenario includes only those changes or upgrades to the building structure, site, equipment, and operating procedures that are necessary just to continue current operations for the entire 20-year period of the economic/SW planning period. A status quo scenario would require administrative changes, for example: limiting access to different user groups during certain operating days/hours; mandatory curbside service; eliminating drop off areas for recyclables; and demand pricing. 6.0 Initial Facility Design Alternatives Screening Process This initial facility screening process will be used to identify 2-3 SW facility design alternatives that could meet the SW facility improvement objectives, while eliminating concepts from consideration that had a fatal flaw; that is, they were not reasonable or did not meet the SW facility improvement objectives. SWF Improvement Objectives – are specific statements of a desired condition(s) or targets that shall be achieved in order to address Jefferson County’s statutory goals, stakeholder needs and existing solid waste facility condition and functional Gaps. Facility Alternatives Screening Criteria – are the standards or specific aspect of the effectiveness (quantitative or qualitative) of the facility improvement actions that are evaluated to assess their suitability to achieve the desired objectives. Criteria are not measurable while “Indicators” are. These criteria will be updated at each stage of the alternatives screening process to accommodate the increased level of detail and feedback received from the task force and community. JC0726-2022-069-Vikek Facility Condition, Design Alternatives and Screening Process 6 Facility Alternatives Screening Indicators – Are specific measurements (quantitative or qualitative) used to demonstrate the extent to which the proposed SW facility improvement achieves the desired outcome During this screening process, facility design concepts will be evaluated qualitatively, primarily using the applicable criteria/indicators, and SWFTF members, guided by the judgment of consultant team members with expertise in the applicable evaluation areas and feedback from the community. To pass the initial facility design alternative screening, all facility design alternatives are evaluated using a “three- level rating scale” as outlined in Table 1. Table 1 - Measurement Scale for Each Design Alternative Rating Extent to which Alternative would adequately achieve the indicators Description 5 Good Alternative would adequately achieve all Indicators 3 Fair Alternative would adequately achieve some Indicators 1 Poor Alternative would adequately achieve a very small number of Indicators or none of them ❖ Screening Process Steps 1. Establish Decision Context a. Review Facility Improvement Objectives b. Review Existing Facility Condition Assessment Results c. Review Initial Community Survey Results 2. Review and Understand Facility Design Alternatives to be Screened a. Review and address any questions 3. Identify Screening Criteria /Indicators needed to achieve the Facility Improvement objectives 4. Address any questions about list of Criteria /Indicators 5. Adjust Criteria as needed 6. Evaluate each alternative against each criteria/indicator 7. Rank alternatives and discuss results 8. Decide and Agree on Which Alternative(s) to Move Forward for Detailed Evaluation JC0726-2022-069-Vikek Facility Condition, Design Alternatives and Screening Process 7 Guided by the results of the total scores from the screening process, SWFTF should agree by modified consensus to accept the results and that the alternatives moved forward are those that best meets the project vision and goals...Key Questions to consider during screening and dialogue are; • Which alternatives can efficiently handle the tonnage and vehicle traffic anticipated for the next 20-year planning horizon? • Which alternatives offer the best opportunities for increased recycling and material recovery? • Which alternatives offer the best opportunities to reduce queuing and congestion? • Allow construction to occur with the minimum of disruption to ongoing solid waste operations? • To the extent practical, separate commercial and self-haul vehicle traffic for safety reasons? • Allow future expansion of the transfer, scale facility, recycling, and maintenance buildings, and non-building assets? • Reduce the carbon footprint? 7.0 Detailed Description of Initial Facility Design Alternatives ❖ Initial Facility Design Alternatives’ Level of Service Level of service (LOS) is a key criteria that will be used to guide the evaluation of the different design facility alternatives. Table 2 below provides a range of service levels (LOS) for recycling from High to Basic and shows the current level of service for comparison. The current level of service is considered high and Public Works staff indicate that they found it to be the same or better than King County and Seattle as measured by drive time between facilities and the types of materials accepted at facilities, as shared with the Solid Waste Advisory Committee in an LOS comparison in 2022. Including additional materials to the ones currently diverted requires careful deliberation on the increase to the tipping fee necessary to offset both the revenue loss and the cost of additional material diversion. Balancing the tipping fee with LOS requires considering whether lower-income residents are able to access the core service (garbage disposal) at the price point. Excluding lower-income residents from the core service with a tipping fee that exceeds their financial capacity would indicate that the County has failed to deliver services equitably. The level of service for public facilities associated with each alternative is provided in Table 3, while detailed descriptions of the four facility design alternatives are provided in Table 4.
