American residential developments of the period, included a racial covenant, stating: “No person of any race or nationality other than the White or Caucasian Race, shall use or occupy any building plot or lot or any portion thereof, except that this covenant shall not prevent occupancy by domestics of a different race employed by the owner or tenant.” ("Domestics" refers to domestic servants.) After World War II, population and growth in the area increased as vacant plots were bought up and homes built. Like the early residents of Murray, many were non-Mormon, blue-collar workers, although Rose Park's residents often worked for major railroad companies, such as Union Pacific, Southern Pacific, and the Los Angeles-Salt Lake Railroad companies, rather than smelters, common in Murray. More recently, one can find accountants, electricians, business managers, engineers, real estate agents and brokers, architects, and police officers among Rose Park residents. Many homes are now being renovated by young families who have moved into the area. The homes are small by today's standards (averaging 1,600 to 1,800 square feet) and are generally constructed of brick though some early stick framed homes are present in the area. Trees (including many varieties of fruit trees) were planted in the neighborhood by young WWII era families. Rose Park now boasts some of the city's largest and most densely spaced trees. On 8 September 2020, a wind storm with category 3 hurricane force winds swept through the area. The winds toppled many of Rose Park's oldest & largest trees, causing property damage and widespread power outages. Super Fund Site In the early 1980s a hazardous site existed near Rose Park near Rosewood Park and east of the Rose Park Golf Course. The state of Utah petitioned the United States Environmental Protection Agency to add it to their list of Superfund cleanup sites. The agency agreed and in 1982 it was added to the Superfund list as "Rose Park Sludge Pit." Local refineries dumped waste products in the sludge pit from 1930 until 1957. The acidic sludge contained carcinogenic polycyclic aromatic hydrocarbons and sulfur dioxide posing a threat to groundwater and surrounding organisms. This was particularly unnerving because much of the municipal water in Rose Park comes from scattered wells. Though no contaminants were ever detected, the threat of contamination was enough cause for action. Amoco oil company was potentially liable for the site and agreed to clean it up
