This document summarizes an Oak Harbor Facilities Plan workshop regarding options for upgrading the city's wastewater treatment plant. It discusses the project goals, schedule, and planning process to date including public and stakeholder input. Eight preliminary treatment alternatives are presented combining potential treatment technologies, sites, and outfall locations. The alternatives will be evaluated against criteria such as costs, environmental and neighborhood impacts, and water quality. The next steps are to refine the alternatives matrix and select a proposed alternative.
12. Summary of U.S. Navy FeedbackKickoff Meeting, S1 Workshop Candidate sites exist on Seaplane Base Areas South of Train Wreck, North of Lagoon, and near Capehart Housing were proposed “Train Wreck” site not favored by NAS Whidbey staff Stepwise process starts with local offices and continues through US Sec. of Navy Cultural resources are a potential issue, particularly near the shoreline Close coordination with local/regional planning and real estate staff is required

40. Collection System Considerations 100% of City flow currently reaches RBC plant Sites near RBC are most efficient Reduce/eliminate pump station and forcemain ± 50% of City flow passes by Old City Shops site Sites further from the RBC site will require extensive (expensive) conveyance improvements Treating flow from Navy Housing with a small, satellite facility may reduce conveyance costs
41. Outfall/Discharge Considerations Existing outfall to Oak Harbor no longer useable Existing outfall to Crescent Harbor requires improvements for long-term use Oak Harbor, Crescent Harbor, West Beach are options (depending on treatment plant location) All locations provide adequate mixing Shellfish harvesting evaluated by Dept. of Health and Dept. of Natural Resources Several agencies have moved outfall to avoid mitigation payments for lost resources
43. Opportunities for Beneficial Reuse In addition to these outfall locations, team will evaluate beneficial reuse opportunities, including: Landscape/open space irrigation Groundwater recharge Habitat creation/improvement
