Parcels of Thurston County, Washington. Thurston County's data set for use in determining issues related to property ownership based on tabular information stored in the ASCEND and SIGMA databases maintained by the Thurston County Assessor's Department.

The fields SEWER_TYPE and WATER_SRC come from a variety of different sources and jurisdictions which the Assessor’s Office has no control of or the ability to audit. The Assessor’s Office appraisers are not experts in determining the exact type of water/sewer system available to a site, and do not make any official determination. These legacy fields are not updated. Local utility providers should be contacted for better information for specific parcels.

Thurston County, WA, US Post Office assigned zip code areas. The purpose of this data is as a general reference only and actual mailing zip codes should be obtained from the US Postal Service. This layer was originally created using USPS TIGER Zip File 2007 tied to 2000 Census Data. It was updated in 2016 using a zip code layer created by TCOMM 911 based off of addressing points. Generally the boundaries between zip code areas have been moved to be coincidental with Thurston County Assessor’s Parcel boundaries. As parcels shift, due to correction, or are changed by subdivision, merge, BLA, etc. the boundaries may become disconnected. Periodically adjustments may be made to realign these boundaries with parcels however there is no regular maintenance plan in place. This layer should be used in conjunction with the Zip Code Points layer which is used to show zip codes associated with US Post Office Box Locations. For example in smaller jurisdictions, like Bucoda, that rely on a post office box rather than rural delivery, the zip code area will reflect the greater rural zip code boundaries and not the localized PO Box zip code.
