(Beaverton, OR) -- The Washington County Sheriff's Office is keeping a close eye on a sinkhole that's appeared in a Beaverton neighborhood. The opening was reported yesterday on Southwest 123rd Avenue at Southwest Denfield Street. Deputies say on the surface, the sinkhole is about the size of a manhole, but below, it's actually about six-feet wide and three to six-feet deep. Crews blocked off the area surrounding the sinkhole and tell Fox-12 it will be repaired at a later date.
