The land where Hilltop sits was originally an unincorporated part of the former Fridley Township, a civil township next to the city of Fridley. The land had a dairy farm and was later the Oak Grove Riding Academy and Stables. The first trailer park, Trailer City, opened on the land in the 1940s; another park, Sunnyside, soon opened next door. Residents of two trailer parks became concerned that the township was planning to remove the mobile homes. In 1956, led by Trailer City Park owner Les Johnson, they approached Columbia Heights and requested to be annexed by the city. Columbia Heights turned down their request, so Johnson circulated a petition to have the residents vote on incorporation. The petition for incorporation passed, 137 to 34, and Hilltop was created. The city was named after a nearby drive-in cinema.
