HistoryA character grade: shown, never part of Mountain Brook’s overall grade.
Alabama towns list about as much on the Register as the country (a typical Alabama town has 2.7 per 10,000 residents, the U.S. 2.4), so Mountain Brook’s 13.2 sits above most of its state (69% of Alabama towns have fewer) while its 29 historic buildings outnumber those of 81% of U.S. towns.
How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share is a Census survey estimate (±5.0 points).

What stands out about Mountain Brook’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The city was originally developed in 1929 by real-estate businessman Robert Jemison Jr., as a suburb of Birmingham 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.
