The 2007 Water System Plan for Water District 19 provides a long-range planning document to assess the adequacy of its water system and meet future needs on Vashon Island. It addresses regulatory concerns, identifies existing system characteristics, and outlines strategies for water conservation, resource protection, operations, maintenance, and capital improvements. The plan also details financial alternatives to implement these recommendations within a twenty-year planning horizon.

This document outlines Section 2, 'Basic Planning Data,' of Water District 19's Comprehensive Plan. It provides an overview of the District's service area, including physical and demographic characteristics, land use, and water consumption trends. The plan analyzes past and projected population, employment, and water demands, with a focus on addressing the existing moratorium on new connections due to capacity limitations. It evaluates the system's ability to meet the needs of current and future residents, presenting projected water demands both with and without conservation strategies. This section serves as foundational data for future land use planning and potential revisions to the Vashon Town Plan in collaboration with King County and the Vashon community.

This section of the Comprehensive Plan for Water District 19 provides a detailed analysis of the existing water system and outlines recommendations for its future maintenance and improvement through 2030.
