Morningside/East side
Defined by its quiet neighborhoods and vibrant retail sector, Morningside is a bustling hive of activity on the city's southeast corner. Morningside is somewhat demarcated by old U.S. Highway 75 at the western end and old U.S. Highway 20 on the northern end. It was originally a streetcar suburb in the late 19th century. Morningside was originally promoted by the entrepreneur and settler Edwin Peters, who made his home near the original commercial center of the suburb, known as "Peters Park." Today, Morningside is a large sprawling area of Sioux City containing numerous distinctive neighborhoods and is home to East Middle and East High schools, Morningside College and Western Iowa Tech Community College. As a whole, the region is a mix of older residential neighborhoods and commercial corridors, as well as home to most of the city's retail and residential growth in the Southern Hills, Commons, Sunnybrook and Whispering Creek areas.
