Due to the foresight of many individuals, this process became a partnership in which jurisdictional politics were set aside so that true land use planning based on the ecosystem rather than political boundaries could take place. We are grateful to the Environmental Protection Agency (EPA), Department of Ecology (DOE) and Puget Sound Water Quality Authority for funding this planning effort, and to Linda Storm of the EPA and Lynn Beaton (formerly of DOE) for their guidance and encouragement during the grant application process and development of the Wetland Integration Plan. In addition, we wish to thank the many dedicated professionals who contributed their time and talents to this plan, including: Tom Hruby of the DOE Shorelines division who has been invaluable to the development and application of the habitat assessment model, analysis of data and formulation of the plan; Rick Huey and Joanne Polayes Wien of DOE's Toxic Cleanup Program, whose efforts made it possible to complete the habitat inventory, assessment, review of data, and the editing and writing of the plan; Gail Colburn of DOE's Toxic Regulatory Program who carefully edited the plan and prepared the extensive "funding sources and technical assistance" appendix, technical glossary and references; Erik Stockdale, Richard Gersib, Jane Rubey Frost and Elizabeth Babcock who made many important contributions during the Technical Committee meetings and field surveys; Linda Storm of the EPA whose assistance as both the grant officer and Technical Committee member ensured a complete and competent document through her careful examination and thorough analysis of all scientific issues; Duane Karna of the EPA whose field experience and scientific knowledge were critical to the completion of both the habitat assessment model and the habitat assessment; Fred Weinmann of the EPA for his important contributions to the development of the habitat assessment model and whose thoughtful review and analysis of early drafts led to substantial improvements in the quality of the plan; Tom Mueller of the Corps of Engineers for his assistance and guidance to the City on Corps regulations regarding the future implementation of this plan; Debbie Knaub of the Corps of Engineers for her careful review of drafts, important contributions on the Technical Committee and patience in explaining the intricacies of the Corps of Engineers regulatory process; Evan Lewis of the Corps of Engineers for his scientific expertise on fisheries issues during the development of the habitat assessment model and for his valuable and insightful input to the Technical Committee during formulation of the plan; Colleen Stinson of the Natural Resource Conservation Service for her valuable input at the Technical Committee meetings and careful review of the final drafts of the plan; Brian Williams of Washington's Fish and Wildlife Department, whose knowledge of and experience with protecting fisheries and marine resources were critical to the development of the habitat assessment model and plan; Bob Zeigler of the Washington’s Fish and Wildlife Department whose generous assistance to both the staff and Technical Committee, including his valuable Estuary field Snohomish Estuary Wetland Integration Plan Acknowledgments Page 1 observations and knowledge of its ecology, provision of other Estuary wildlife data sources, and careful scientific scrutiny of all issues, resulted in a significantly better plan; Ted Muller of Washington’s Fish and Wildlife Department, whose wildlife expertise and knowledge of Estuary wildlife and ecology were of great assistance to the development of the habitat model and plan; Tony Opperman of the Washington Department of Fish and Wildlife for his contributions to the development of the habitat assessment model; Sky Miller of Snohomish County Surface Water Management who has been instrumental in coordinating County participation in development of this Plan and whose hydrological knowledge of the Estuary has been very important to the development of the management plan; Janet Carol of Snohomish County Surface Water Management whose extensive knowledge of bird usage within the Estuary and in-depth review of the wildlife analysis made important improvements to the plan; Paul Meehan Martin of Snohomish County Public Works whose field assistance, broad knowledge of Estuary wildlife, significant contributions to the Technical Committee discussion of wildlife issues, and review of several drafts resulted in a greatly improved final product; Darrell Smith whose comprehensive knowledge of Estuary wildlife and contributions to the Technical Committee were helpful to development of the habitat assessment model; Jon Houghton of Pentec for his in-depth scientific knowledge and expertise on fishery resources and biology within the Snohomish Estuary and for his detailed and helpful comments on the drafts; Dyanne Sheldon for her keen insights and contributions to the Technical Committee which were very helpful to the development of the model; Jane Zimmerman of the City of Everett Public Works Department for her important technical and scientific contributions on water quality issues during development of the model and for providing valuable direction during Technical Committee debate over difficult issues; Dan Thompson of the City of Everett Public Works Department for his scientific and technical input at the Technical Committee meetings and during the development of the final plan; Becky Herbig for her many innovative contributions during the formulation of the plan and her wildlife expertise which was invaluable to completion of the field work and the plan's extensive wildlife analysis. We are also very grateful to the citizens, property owners and environmental and industrial experts who sat on the User Group Committee. We thank Monty and Shirley Holmes, Bob Johnston, Everett Alexander, Barney Bagwell, Dave Buse, Barry Margolese, Joanne Bryant, Myra Williams, Karen Williams, Daryl Williams, Chris Mann, Stuart Triolo, Laura Zalesky, Rob Ryan, Werner Furrer, Herb Carpenter, Sally Van Niel, Anne Robison, Kathie Joyner, Sky Miller, Debbie Terwilliger and Dennis Gregoire for their patience with and participation in this complicated process and the respectful manner in which they reviewed all members’ points of view, as well as their contribution of many important observations and ideas regarding the Estuary Management Plan. Their contributions resulted in a Management Plan that represents a cooperative balancing of interests and objectives yet protects and maintains overall the resource values of the Snohomish Estuary.
