The US Government Accountability Office (GAO) Report on Addresses and Orthoimagery was made public and Washington was one of five states interviewed for this report.
Along with the Geospatial Program Office's interview, visits and presentations were made by the Department of Revenue and Transportation.
Specific recommendations were made on pages 72 and 73. It is relatively unusual for GAO to make specific recommendations to Congress, but they heard the states message on Titles 13 & 39 and the message about Imagery for the Nation.
