Known Errors/Qualifications: Orthophoto washes are more detailed and are not edgematched to DLG washes. In the current regulatory scheme all washes between 2,000 CFS and 10,000 CFS are stored in the 5,000 to 10,000 category pending review.
Lineage: Future plans to merge this layer with layer Wash_02K and the City's layer wash_ci, then rectify.
