Washington State Parcel Database

Digital parcel data stored in a geographic information system has become a critical source of information for resource land managers, community development, infrastructure maintenance, homeland security and business development. Washington State leaders, managers, researchers and business continually use GIS parcel data for decison making, science and resource management.

Redundant Efforts are Costly

It is recognized by various city, county, state and other government entities that having timely access to GIS based parcel data is critical. Currently no single source of parcel information exists in Washington State. Each public or private entity must request data directly from the counties which comes in myriad data formats and utilizes differing attribute coding schemes. Many counties have data license agreements which prohibit or severly restrict the ability of one user to share parcel data with another making cross-agency or interdisciplinary research difficult, expensive and variable since no two groups are using the same data. Redundant efforts to collect, store and manage county parcel data are occuring at all levels of government.

A Statewide Dataset is Needed

The Rural Technology Initiave, The Family Forest Foundation, The Washington Farm Forestry Association, The USDA Forest Service, Washington State Government Agencies and various other organizations are working together to create a signle source for Washington State county parcel data. The primary purpose of this effort is to develop a consolidated, consistent and documented parcel GIS dataset for use by public entities and other interested parties. Using the seamless statewide parcel database as a foundation the Rural Technology Initiative, the Family Forest Foundation and the Washington Farm Forestry Association are producing a Family Forest Database to assess, better understand and document the geography of family forests in Washington State.

Goals of the Washington State Parcel Database

  • Establish relationships with Washington's 39 counties to uderstand their parcel data needs
  • Collect parcel data from Washington's 39 counties
  • Survey current and potential parcel data users to identify what components of parcel data are important to their business needs
  • Develop a common statewide parcel data format that meets the needs of identified users
  • Work with each county to develop a protocol for transformation of individual county data into a common statewide format
  • Transform Washington State county data into common statewide format, documenting proceedures and protocols for future updates
  • Implement a collaborative parcel data distribution and update service
  • Identify long-term funding sources for support personnel, updates to the database and maintenance of hardware

Goals of the Washington State Forestland Database project

  • Leverage the Washington State Parcel Database to produce a dataset which facilitates an understanding of the geography of family forests and their ecological, economic and social contributions to the state
  • Create a historical record of the distribution of family forests around the state to better understand trends on these lands

Anticipated Benefits

  • Spatial distribution and numbers of forest lands by ownership types
  • Land use planning, zoning, and forest land relationships analysis
  • Framework for quantification of environmental services
  • Effectiveness monitoring for Endangered Species Act
  • Watershed analysis
  • Fire risk distribution

Parcel data from individual counties, combined with forest cover data, will form the base for distinguishing family forests throughout the state.
