A bug has been logged for the 403 error which is generated when trying to download large datasets through the Download menu. As a workaround, the zipped file geodatabase is available here:https://www.arcgis.com/sharing/rest/content/items/d04a50e44fbd4497bb57830b52fe5a2b/dataThe Washington State Land Use coverage was produced from digital county tax parcel layers using Department of Revenue (DOR) two digit land use codes (see; WAC 458-53-030, Stratification of assessment rolls - real property). Land use attribute data has been normalized for all county parcel data to conform to the two digit DOR codes. All county parcel layers are dissolved using the normalized land use code. No county parcel information remains in this data other that what geometry remains from the dissolve process.
