The bayside hills between Rosecrans Street and Chatsworth Boulevard north of Nimitz Boulevard are known as Loma Portal. A distinctive feature of this neighborhood is the location of street lights in the middle of several street intersections instead of on the sidewalk. Loma Portal lies directly in the takeoff pattern for planes from Lindbergh Field, making it the home of the "Point Loma Pause" where all conversation ceases temporarily due to airplane noise. The east-west streets in Roseville and Loma Portal are known as the "alphabetical author streets". The streets are named for authors in alphabetical order from Addison to Zola, with a second partial cycle from Alcott to Lytton.
