Supplemental Information: A combination of remote sensing (orthoimagery) as well as field collection, utilizing GPS technology was used to create this feature class. Sites were first generated using orthoimagery and King County assessor data. Any sites that were not found on the orthoimagery were collected using vehicles equipped with DGPS units. This layer is updated regularly, with primary source of updates coming from the addressing authorities for each community within the county. Explanation of CTYNAME: This is the city name that most likely represents the jurisdictional city in which the address resides from the USPS Zip Plus 4 data tables. Note: In order to ensure the right zipcode is selected from the Zip Plus 4 tables , a comparison is made with this city name and a city name derived from an overlay w/ city_area. Explanation of POSTALCTYNAME: This is the city name that most likely represents the postal city in which the address resides from the USPS Zip Plus 4 data tables. In most cases the CTYNAME and the POSTALSCTYNAME are the same. NOTE: If the FIELDS are NULL, That is an indication that the address point did not have a record in the USPS Zip Plus 4 data.
