The King County region is facing competing demands for water as the population increases, the climate changes, land is developed, and habitat is altered. Because water flows across socio-political boundaries and water law involves a range of responsible entities, some form of cooperative regional planning among multiple jurisdictions is needed to address these issues.
In July 2005, King County Executive Ron Sims convened a broad set of stakeholders to discuss how to tackle regional water planning. After several meetings, this group agreed to first cooperate on defining and collecting data on specified technical issues. The resulting planning-level technical information was expected to be useful to state agencies, water utilities, cities, counties, other governments, and other parties interested in internal and broader regional water planning activities. Successful collaboration could also encourage participation in future coordinated planning efforts. Seven technical committees were convened and have produced reports on their respective topics.
King County has prepared a Synthesis of the Regional Water Supply Planning Process, which summarizes the contents, recommendations, and conclusions from each technical committee report and offers possible next steps for each topic. Included is a matrix of tools and methodologies developed or reviewed by the technical committees that may be useful to water utilities in either their own planning and management activities or in other regional processes. The report closes with broad conclusions and possible next steps for King County, noting that King County anticipates using information, data, and tools developed through this process where appropriate in its own various planning and management activities and in partnerships with others.
Synthesis of the Regional Water Supply Planning Process is provided in Adobe Acrobat format for compatibility with a wide variety of browsers and computer systems. For help with Acrobat, please visit the Adobe Reader (external link) page from Adobe Systems.
