A Look Back

On August 19th, 1974, the Columbia County Planning Department was born into existence by Resolution 74-17. In 1990, Washington State passed the Growth Management Act, mandating Washington counties to craft development regulations, including the Comprehensive Plan.

Columbia County last completed a full comprehensive plan update with the adoption of the Columbia County 2008 Comprehensive Plan. That plan has been amended regularly over the years to address specific issues, but the complete review process now being undertaken allows for addressing new priorities and broader policy issues.

As with the current update, earlier plans relied heavily on public input. It is both fun and enlightening to look back at the results of past surveys, such as this one, taken in 1973.

Looking Forward

The Columbia County Comprehensive Plan is the long-range guiding policy document for all land use and development regulations in unincorporated Columbia County, and for regional serviced throughout the County including transit, sewers, parks, trails and open space.
