The city was originally developed in 1929 by real-estate businessman Robert Jemison, Jr., as an extensive residential subdivision along the ridges known as Red Mountain and Shades Mountain. It was incorporated on May 24, 1942. The plans, by Boston-based landscape architect Warren H. Manning, called for estate-sized lots along winding scenic roads and denser commercial development centering on three picturesque "villages": English Village, Mountain Brook Village and Crestline Village. Most of Mountain Brook's development preserved the existing trees: 92.03% is under tree cover, one of the highest ratios in the nation. Residential sections such as Cherokee Bend, Brookwood Forest, Overton, and Crestline have houses in a forest setting, with a recreational network of bridle paths. This has protected the area from urban encroachment.
