I am currently researching the change that was made sometime in the 1920's. Currently, all E-W streets north of Sheridan are NE or NW, while streets south of Sheridan are SE or SW. N-S streets east of Santa Fe are NE or SE and streets west of Santa Fe are NW or SW. Numbered streets are E-W only. There is an occassional named street running E-W (Sheridan and Reno come to mind), but they are rare.
