The histogram for Seattle looks unconvincing for me, because the entire downtown-pike-denny area is slanted to align with the coastline ( https://www.google.com/maps/@47.6090857,-122.3407184,15z ). Possibly due to weighting?

North of Lake Union and most of West Seattle are responsible for that plain look N-S grid. Zoomed in, it seems to better reflect the petty feuds.
