El Porto is located north of 38th Street between the ocean and the City of El Segundo. Formerly this area was an unincorporated portion of Los Angeles County. It is developed with a mix of commercial and multi-family properties and has the highest residential development density within Manhattan Beach. Many of the 30-by-90 foot lots have two residential units. This area slopes steeply toward the beach. El Porto was annexed by Manhattan Beach in November 1980 and is now referred to as "North Manhattan Beach."
