1940s, post the Depression/ New Deal growth wasn’t the beginning of Cleveland Park now was it?

The data I’m using is from the late 1800s when the Rock Creek Railway line via the Chevy Chase Land Company built the infrastructure for Connecticut Ave, as well as the failure of the Cleveland Park Company, and the eventual success of the Miller brothers - ultimately, none of these entities were trying to compete with the longtime established villages of Georgetown and Tenallytown (Tenleytown) when they finalized the designs & built out Lower Cleveland Park.

The movie theater, the park & shop, and the automobile literally drove people to the area, and helped redefine the streetcar suburb in the 1940s (and post war 50s) — places to eat/ buy groceries, and be entertained, as well as the ability to get one’s car serviced were the primary draws for that neighborhood, relegating retail shopping to being secondary ~ which it still is to this day.
